Abstract: This invention provides a non-fibrous combustible filter aid for vacuum pre-coat filter units which is effective to maintain a filter bed coating on rotary filter drums just sufficiently porous to pass the liquid of a slurry while retaining the slurry solids thereon and is capable of being scraped off the bed in thin film form with the slurry solids thereon. The filter aid comprises relatively non-compressible non-fibrous granular charcoal or nut shell particles having a dry bulk density from about 0.3 to about 0.6 grams per cubic centimeter, a particle density of about 1.4 to 1.7 grams per cubic centimeter and a particle size range of 30 to 125 microns. The filter aid of this invention is capable of being burned with the solids deposited thereon to recover the heat value thereof or to dispose of the solids, is free from silicates or other non-combustible ingredients, and is devoid of fibers which will interfere with the proper operation of the filter unit.

Abstract: Filter drums of desired diameters and axial lengths are built up from cylindrical modules supported in end-to-end relation on a through axle. Each module has a cylindrical frame composed of end rings connected by and supporting a ring of circumferentially spaced longitudinal bars. A grid formed in the flat by welding spaced parallel transverse ribs to underlying spaced parallel longitudinal rods is rolled into a cylindrical shape and wrapped around bars of the module with the rods of the grid forming hoops which are welded to the bars. The through axle has end heads and intermediate spiders mounted thereon. The outboard rings of the modules forming the end sections of the drum are secured to the heads and the inboard rings of these end modules are secured to the end rings of the intermediate modules with spider legs on the axle secured to one ring of an adjacent pair of rings. One or more filter cloths are then wrapped around the ribs of the resulting drum to form the outer screen filtering periphery for the drum.

Abstract: An apparatus for discharging contents of a bag which includes an enclosure having a pair of pans mounted for pivotable movement therein, a bag spike associated with each pan mounted for movement along the pivot axis of the pan between a position retracted from the pan to a position impaling a bag resting on the pans, an arrangement for cutting a bag resting on the pan and an arrangement for tilting each of the pans on their axes so as to dump the contents of a bag cut by the cutting arrangement into the bottom of the enclosure, which has an arrangement for removing the contents therefrom. An advantage of this device is that all opening of the bag occurs within the enclosure to minimize contact of the contents of the bag with the operator. To remove dust and air from the substantially empty bags, flattening weights are provided above each pan in the cover and are released to flatten the bag to expel dust and air from the empty bag.

Abstract: An apparatus for discharging the contents of bags containing flowable material includes a frame, with a pair of bag spikes mounted generally parallel to, and coplanar with, one another on the frame. A pair of bag pans is movably mounted on the frame so as to be engageable with the bag spikes. Each of the pans is selectively pivotable around a respective axis defined by each of the bag spikes. The bag pans are movable between a first, load/unload position wherein the bag pans are out of engagement with the spikes, and a second, engaged position wherein the bag pans are in engagement with the spikes. A knife assembly is provided that includes a knife arm having a first end pivotably mounted to the frame, and a second end upon which is disposed a knife member. The knife assembly is pivotable between a severing position wherein the knife member extends between the bag pans, and a rest position wherein the knife member is out of the plane defined by the bag pans. A bag pan drive mechanism is mounted on the frame, and is adapted to move the bag pans between their load/unload and engaged positions. A knife actuator mechanism is also mounted on the frame. The knife actuator mechanism is adapted to move the knife assembly between the severing position and the rest position. A bag pan pivot mechanism is also mounted on the frame, and is adapted to selectively pivot the bag pans about the axes defined by the bag spikes.

Abstract: This invention increases the efficiency and flow rate of rotary drum filtration and makes possible the use of such filtration for volatile and high temperature materials. According to the invention a rotary drum filter unit operates continuously in a pressure vessel and solids are intermittently discharged from the vessel. The filtered solids are scraped from the drum periphery and dropped into a trough in the vessel communicating with a discharge passageway. When the passageway is filled with solids, a shroud, driven by a reciprocating ejector traps the solids in the passageway. The ejector compacts the trapped solids forming plugs which are sequentially discharged from the pressure vessel. The filter unit is fixed to a removable end head for the pressure vessel which has a wheeled carriage riding in the vessel and the vessel in turn is carried on wheels so that when the end head is released from the vessel, the filter unit can be exposed for service such as the replacement of filter screens and cloths on the drum.

Abstract: A longitudinally elongated settling tank with a converging longitudinal hopper bottom along the length thereof has a longitudinally elongated travelling bridge reciprocating continuously or intermittently through a relatively short stroke between the inlet and outlet ends of the tank from which depends a plurality of longitudinally spaced sludge pick-up heads each sucking sludge from a zone in the bottom of the tank during a preset cycle. Liquid fed into one end of the tank forms a settling pond from which clarified liquid flows over longitudinal weirs at the opposite end of the tank. Because of the short stroke of the bridge, the tank can be reinforced with internal framework between the paths of the suction heads permitting use of lighter sheet metal for the tank. A skimmer is automatically lowered into the top of the pond as the bridge advances to sweep oil, scum, and other material floating on the pond into an outlet and is retracted above the pond on the return stroke of the bridge.
