Abstract

Transfer equipment 1 for discrete material includes a cyclone separator housing 2 having a valved solids outlet 6, the valve 8 being operable by means of an interconnection with a filter bag 20 enclosed within a casing 14 to which suction is applied. Upon the application of suction the outlet 6 is closed and air entrained particles of material enter and are deposited in housing 2, the air passing to exhaust through the filter bag 20. The discontinuance of applied suction causes the valve 8 to open thereby occasioning discharge of materials from the housing 2 through outlet 6. <IMAGE>

Description

SPECIFICATION Transfer equipment for discrete material This invention relates to transfer equipment for discrete material.
In particular, the present invention has reference to transfer equipment for dry granular or particulate material by suction. An object of the invention is to provide improved transfer equipment which obviates or reduces the need for vacuum sealing on a main receiver to which the material is to be transferred. According to the invention transfer equipment includes a cyclone separator housing having an inlet for gas and solids, a solids outlet at the base of the housing, a closure member for the solids outlet and operable to close the outlet upon application of suction within the housing, a vortex finder in the housing leading to a gas outlet, a casing enclosing a filter bag having an open mouth communicating with the gas outlet of the cyclone separator housing, and a suction port on the downstream side of the filter bag.The inlet to the cyclone separator housing is preferably arranged tangentially and the vortex finder may conveniently be in the form of an inverted hollow frusto-conical member fixed internally to the housing.
The casing may be mounted on top of the housing such that the gas outlet of the housing registers with the open mouth of the filter bag. In this instance, the filter bag may be provided with an attachment plate carrying a tie-rod for connection to the closure member for the solids outlet. The closure member may be in the form of a cone valve.
In an alternative embodiment the casing and the housing may be positioned side by side, there being provided a suitable flow connection between the gas outlet from the housing and the open mouth of the filter bag. In this embodiment, an outlet for solids material is provided in the casing together with an associated closure number operable in use by means of the suction effect. For example a similar arrangement to that described supra in relation to the housing could be adopted, namely an inter-connection between the filter bag and the associated closure member of the casing. A suction operated diaphragm would then be provided in the cyclone separator housing for operating the closure member of the solids outlet.
As an alternative to cone valves, other closure members may be used, for example hinged flaps or doors.
By way of example only, one form of transfer equipment is described below with reference to the accompanying drawing which is a diagrammatic sectional side view of the equipment.
Referring to the drawing, transfer equipment 1 includes a cyclone separator housing 2 having a tangential inlet 3 in an upper cylindical part 4 which leads to an inverted frusto-conical part 5 provided with a solids outlet 6 and a closure member therefor in the form of a cone valve 8. An inverted hollow frusto cone 10 is secured coaxially within the housing 2 in its upper part 4 and extends downwardly into the part 5 to constitute a vortex finder.
The top of the cone 10 forms a gas outlet 12.
A casing 14 is mounted vertically above the housing 2 and is fixed thereto by means of a flanged connection 16. At the top of the casing 14 is a suction port 18 and secured within the casing 14 is a filter bag 20 the open mouth 22 of which communicates directly with the gas outlet 12 of the housing.
The base of the filter bag 20 has an attachment plate 26 which carries a tie-rod 28 connected to the cone valve 8.
In use, the tangential inlet 3 of the cyclone separator housing 2 is coupled to a supply (not shown) of particulate solids. Suction is applied by suitable means (not shown) to part 18 and as a consequence the filter bag 20 is drawn towards the top of the casing 14. The upward movement of the filter bag 20 causes the tie-rod and thus the cone valve 8 to rise, the latter sealing the solids outlet 6. At the same time gas, e.g. air, and solids are induced through the inlet 3 and vortical flow is generated within the housing 2 around the cone 10, the solids being centrifruged and descending to the base of the part 5 of housing 2. The air together with any entrained fine dust particles ascend through the cone 10 and outlet 12 into the filter bag 20, the air passing through the bag 20 to the port 18 and the particles being captured by bag 20.When a sufficient batch of material 30 is deposited in the housing 2, the application of suction is discontinued. The filter bag 20 collapses upon itself and may be assisted in so doing by the provision of light spring fingers (not shown).
This collapse together with the weight of material causes the valve 8 to open thus discharging the material from housing 2, the downward movement of the valve 8 and tierod 28 being limited by abutment of the attachment plate 26 with a stop 29 within cone 10. The material is discharged into any suitable container (not shown) which may be rigid or flexible and provided with adequate sealing to prevent any dust drift. The downward movement of filter bag 20 also causes any accumulated dust on the bag to discharge into the housing 2 and thence through outlet 6.
The operation of this equipment is repeated dependent upon demand for the discrete material which may in one application be particulate coal or ash. Other material may of course be transferred using the equipment described which effectively functions as a suction operated separator/dump valve.
