Abstract: A sampling apparatus is characterized by a sampler operable to obtain samples of liquid product from a body of product in a vessel. The sampler includes a plunger having a sample receiving recess and a connecting device couples the sampler to the vessel at an aperture to the vessel. The sampler is attached to the connecting device and the connecting device is moveable between a first position placing the sampler into, and a second position taking the sampler out of, communication with the aperture. With the connecting device in the first position, the plunger is reciprocated to extend the plunger and its recess through the connecting device and vessel aperture into product in the vessel to receive a product sample in the recess. The plunger is then retracted from the vessel and through the connecting device to deliver the product sample to a collection point. During reciprocation of the plunger, a liquid seal is maintained between the vessel interior and sample collection point, and when the connecting device is moved to the second position, the sampler can be detached from the connecting device for service or repair, without escape of liquid from the vessel through the connecting device. Advantageously, the sampler remains stationary during movement of the connecting device between the first and second positions, so that additional space in which to accommodate movement of the sampler is not required when attaching the sampler and connecting device to the vessel.

Abstract: A sampling apparatus is characterized by a sampler body having a bore and a forward opening from the bore communicating with the interior of a vessel containing fluidized product in which strands, viscous strings and particles may be entrained. A plunger assembly in the bore is generally cylindrical along a longitudinal axis and has a sample receiver and cutters. The sample receiver is generally tubular and has a plurality of arcuately spaced longitudinal slots extending radially between an outer surface and a hollow interior of the sample receiver, and individual cutters are in facing relationship at opposite ends of the bore. A pneumatic motor reciprocates the plunger in the bore in a forward direction to a sample obtaining position where the sample receiver and cutters are extended at least partly out of the forward bore opening and into the interior of the process line to obtain a sample of fluidized product that flows into and fills the sample receiver passages and hollow interior. The motor then reciprocates the plunger rearward to a sample delivering position where said sample receiver and cutters are retracted into the bore for conveying the sample of fluidized product in the sample receiver to a sample delivery position in the bore. The sample receiver and cutters are a unitary structure and the cutters cooperate with the sampler body in both directions of reciprocation of the plunger assembly to slice through any strands, viscous strings and particles that extend radially outward from the sample receiver slots and would otherwise impede reciprocation of the plunger assembly.

Abstract: A sampling apparatus is characterized by a housing having a bore communicating at one end with the interior of a vessel containing fluidized product. A plunger assembly in the bore has a sample chamber intermediate its ends and is reciprocated to project the sample chamber out of the bore and into the vessel to receive a sample of product therein, and to then retract the sample chamber from the vessel and into the bore to a sample collection point. Forward and rearward seals on the plunger to opposite sides of the sample chamber always maintain a liquid seal between the one end of the bore and the sample collection point. The rearward seal comprises a shear bearing having a circumferential groove that receives and retains fluidized product in sealing relation to the bore to seal the shear beating and thereby the plunger assembly to the bore. The product collection point in the bore includes a plurality of passages in the housing that communicate with the bore and are sized to prevent passage therethrough of relatively large product particles. Upon reciprocation of the plunger assembly to project the sample chamber into the vessel, the shear beating cuts off and conveys back into the vessel any pieces of product that became caught in the passages during the previous sampling cycle and extend into the bore.

Abstract: A sampling apparatus is characterized by a sampler and a sample collection station. The sampler is stationary and periodically delivers discrete product samples to a stationary inlet to the sample collection station. The sample collection station includes a deck having a plurality of passages in linearly aligned spaced relationship, a plurality of sample collection containers, and inlets to the sample collection containers that are in communication with associated ones of the deck passages. The deck is linearly indexed in both directions of movement along the linear alignment of the deck passages to place selected ones of the deck passages into communication with the stationary inlet, so that product samples delivered by the sampler to the sample collection station are directed into selected ones of the sample collection containers. The use of a plurality of sample collection containers at the sample collection station provides an increased product sample collection capacity and extends the time for which product samples may be collected before the station reaches its capacity and requires operator attendance to replace full with empty sample collection containers. A generally side-by-side alignment of the sample collection containers provides an unobstructed view of the containers to allow all of the containers to be simultaneously visually inspected by an operator.

Abstract: A sampling apparatus is characterized by a sampler housing coupled to a movable valve of a connecting device. The housing and the movable valve have bores that are in communication and axial alignment. One end of the valve bore communicates with the interior of a liquid containing vessel. A plunger is in the housing bore and has an annular recess intermediate its ends. The plunger is reciprocated in the housing and valve bores to project the recess into the vessel to receive a sample of liquid therein, and to then retract the recess from the vessel and through the valve and housing bores to a sample collection point in the housing. Plunger seals maintain a liquid seal between the vessel interior and the sample collection point in the housing during reciprocation of the plunger. The valve is movable between an operative position where the one end of its bore communicates with the vessel interior and an inoperative position where the one end of its bore is out of communication with the vessel interior. Movement of the valve to the inoperative position enables the sampler housing to be disconnected from the valve for maintenance, repair or replacement without allowing liquid to escape from the vessel through the valve bore.

Abstract: A sampler for communicating with the interior of a vessel containing dry granular or powder materials extracts a sample of the material and conveys it to a point of collection. The sampler includes a tubular probe having an inlet opening toward an inner end and the probe is reciprocable into and out of the vessel for a flow of material into the inlet and through the probe to an outlet from the probe. To assist the material flow a jet of fluid is introduced into the inner end of the probe to aspirate material into the inlet opening and convey it through the probe, and when the probe is retracted from the vessel the jet purges the same of residual material. One or more valves are provided to control the jet of fluid and enable a momentary flow of fluid outwardly of the inlet opening when the probe is retracted to clear the opening of any material lodged therein.

Abstract: A sampling apparatus for communicating with the interior of a vessel containing a liquid at an elevated temperature extracts a liquid sample of predetermined volumetric displacement from the vessel and maintains the sample at or above the elevated temperature or within a selected temperature range while conveying the same to a point of collection. If desired, an environment control medium may be maintained about the sample while within the sampler. In this manner, the sampler may advantageously be used to obtain samples of liquids which solidify, thicken, change in property and/or become unstable unless temperature controlled, or which must be maintained in a controlled environment during collection.

Abstract: A sampling apparatus is characterized by a housing having a bore extending therethrough, which is supported with one end of the bore communicating with the interior of a liquid containing vessel and with an opposite end of the bore being outside of the vessel. A plunger or cylinder rod is positioned in the bore and has an annular recess intermediate its ends of a length longitudinally of the plunger which is less than the length of the bore. A pneumatic cylinder is connected with the plunger at the opposite end of the bore for reciprocating the plunger in the bore to project the recess into the vessel to receive a sample of liquid therein, and to then move the recess from the vessel and to an intermediate point in the bore whereat a housing outlet port receives the sample. First and second seals on the plunger to opposite sides of the recess maintain a liquid seal between the one end of the bore and the outlet port during reciprocation of the plunger, and a third seal is on the plunger toward the opposite end of the bore. The third seal absolutely blocks passage of any sampled liquid to the pneumatic cylinder, and wipes the bore clean between the opposite end thereof and the outlet port with each reciprocation of the plunger.
