Described stream film cutting segregation apparatus includes circular horizontal plate, and the inner circle of horizontal plate is provided with columned separating plate downward vertically, and separating plate lower end reaches in centrifugal classification device;
It is the water pump connected by pipeline that described back-flushing feeds device;
Described product collecting device is that ring-type barrel structure is around centrifugal classification device, and by dividing plate, space in cylinder is divided into urceolus and inner core, wherein the height of outer tube wall exceedes dividing plate, and the height of dividing plate exceedes inner tube wall, inner tube wall is connected with the inwall of centrifugal classification device, and dividing plate is connected with horizontal plate.
Position and the degree of depth of the separating plate of described stream film cutting segregation apparatus can regulate as required.Described back-flushing feeds and is respectively equipped with valve and water pressure gauge on the pipeline of device.
Beneficial effect: in the course of the work, centrifugal classification device high speed rotating also drives Bed for Fine Coal granule to do centrifugal motion to the fine centrifugal classification equipment of continuous pulp discharge of the present invention, enhances centrifugal classification effect;Centrifugal classification device is provided with recoil water hole, feeds back-flushing, further enhance granule separating effect, improve the efficiency of separation in sorting district;Centrifugal classification device is provided with stream film cutting segregation apparatus and carries out cutting stream film; make case of low density loads and high density feed separation and be collected separately, cancelling reflex circle, do not have high density material and can be deposited in reflex circle; without shutting down cleaning, it is achieved thereby that continuous pulp discharge.The Bed for Fine Coal centrifugal classification equipment of continuous pulp discharge of the present invention, technique is simple, and energy consumption is low, and equipment is simple, good separation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Bed for Fine Coal centrifugal classification equipment of continuous pulp discharge of the present invention.
In figure: 1-centrifugal classification device, 2-stream film cutting segregation apparatus, 3-back-flushing feeds device, 4-product collecting device, 5-inwall, 6-outer wall, 7-drive link, 8-recoils water hole, and 9-back-flushing is to hand-hole, 10-separating plate, 11-horizontal plate, 12-valve, 13-water pressure gauge, 14-urceolus, 15-inner core, 16-driving belt, 17-motor.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
As shown in Figure 1, the Bed for Fine Coal centrifugal classification equipment of continuous pulp discharge includes motor 17 and driving belt 16, it is characterised in that: it includes that centrifugal classification device 1, stream film cutting segregation apparatus 2, back-flushing feed device 3 and product collecting device 4;
Wherein product collecting device 4 is arranged on the outside of centrifugal classification device 1, and stream film cutting segregation apparatus 2 is arranged between product collecting device 4 and centrifugal classification device 1, and back-flushing feeds device 3 and is arranged on below centrifugal classification device 1.
Described centrifugal classification device 1 includes inwall 5, outer wall 6 and drive link 7, cavity is left between inwall 5 and outer wall 6, being furnished with the multiple recoil water holes 8 communicated with cavity on inwall 5, drive link 7 is hollow structure, and is provided with back-flushing on chamber portion to hand-hole 9 extending into;
Described stream film cutting segregation apparatus 2 is arranged on the top of centrifugal classification device 1, described stream film cutting segregation apparatus 2 includes circular horizontal plate 11, the inner circle of horizontal plate 11 is provided with columned separating plate 10 downward vertically, separating plate 10 lower end reaches in centrifugal classification device 1, and position and the degree of depth of the separating plate 10 of described stream film cutting segregation apparatus 2 can regulate as required;
