Abstract:
Mixing device 1, dosing container and mixing hopper for mixing a synthetic starting material with an additive, in particular a granular additive or additive in powder form, comprising a mixing housing 10 with an inlet 14 for allowing the substances into a mixing chamber 12 bounded by the mixing housing and an outlet 16 for discharging the substances from the mixing chamber in mixed form, wherein a rotor body 11 is provided on a rotatable shaft 17 in the mixing chamber and comprises on a side a number of rotor arms 18 extending parallel to the shaft in the direction of an opposite wall of the mixing housing 10, and wherein the opposite wall of the mixing housing is provided with a number of stator arms 19 extending parallel to the shaft in the direction of the rotor body, and wherein a mixing hopper is provided having an infeed side for receiving a flow of the substances for mixing and an outfeed side which is in open communication with the inlet of the mixing housing 10, and wherein a dividing body is provided between the infeed side and outfeed side in order to divide the flow of the substances for mixing into a number of at least substantially equal part-flows.
Abstract:
This invention relates to a filling apparatus (2) and a process for intermittently receiving and discharging specific quantities of bulk product, in particular for delivering specific quantities of bulk product from a weighing machine to a packaging machine. The filling apparatus (2) comprises two partial vessels (8, 10), with each partial vessel (8, 10) comprising a feed opening (20, 22) and an outlet opening (26, 28). Furthermore, an outlet element (30) is provided which is movable at least into a first and into a second position. In the first position, the outlet element (30) closes the outlet opening (26) of a first partial vessel (8) and releases the outlet opening (28) of the second partial vessel (10). In the second position, the outlet element (30) closes the outlet opening (28) of the second partial vessel (10) and releases the outlet opening (26) of the first partial vessel (8).
Abstract:
A combinatorial weighing system (100) which comprises a plurality of weighing heads (5). Further comprised is a collection unit (120) which is composed of a plurality of collection means arranged below hoppers of the weighing heads (5), respectively. Thus, the articles, which have been selected to an optimum added weight combination and discharged from the hoppers of the weighing heads (5), are conveyed inward by the collection means of the collection unit (120), respectively, until they are discharged to a collection chute connected to the inner end of the collection unit (120).
Abstract:
The present invention provides a method of measuring an amount of a substance depleted from a storage unit (12), including the steps of : supporting the storage unit (12) on a vehicle (10), measuring a first weight of the storage unit and any liquid substance contained in the storage unit (12), allowing a quantity of the liquid substance to be discharged from the storage unit (12), measuring a second weight of the storage unit (12) and any liquid substance contained in the storage unit (12), and determining the amount of liquid substance discharged or allowed to be discharged from the storage unit (12) based on the first weight measurement and the second weight measurement.
Abstract:
A hopper device for a combined weighing apparatus includes a bracket (1), a hopper (2) fixed to the bracket (1), gates for discharging which are arranged on the bracket (1) and located corresponding to the discharging end of the hopper (2), and a drive unit (3) for driving the gates arranged on the bracket (1). The gates includes a front gate (4) and a back gate (5) which are located opposite. A connecting mechanism is installed between the front gate (4) and the back gate (5).
Abstract:
A mass flow metering system 1 according to the invention comprises a metered vessel 2 for receiving a flow of froth via a conduit 11. The metered vessel 2 is suspended from mass measuring means In the form of load cells 8, 9 and 10 within a second outer vessel 14. The metered vessel 2 has discharge opening 13 for discharging the froth from the vessel, and a discharge control valve 3 associated with the opening for controlling the discharge of froth from the metered vessel. The metered vessel 2 has a level sensor 5, located in the metered vessel at a predetermined level and associated with the valve 3 for opening the valve when the predetermined froth level is reached. In use, the system operates periodically and in cycles, which alternates between a measuring cycle and a cleaning cycle. There is further provided a method of measuring the mass flow of continuous flowing slurry in line.
Abstract:
A weighing bucket (17) receives product (13) dumped from an overlying holding bucket (15) and causes an underlying load cell (18) to produce an electrical signal representative of the weight of the product in the weighing bucket. After being weighed, the product is swept out of the weighing bucket by a high volume blast of low pressure air produced by an air entraining nozzle (30). As a result of using air to empty the weighing bucket, the weighing bucket requires no doors or other moving parts and thus may be constructed with high stiffness and with a high natural frequency to reduce low frequency disturbances of the weight signal and to improve the accuracy of such signal as well as to reduce the time required for the weighing cycle.
