Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of a filter disc construction;
FIG. 3 is a schematic view of a distribution plate.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, an automatic filter cloth regeneration device for a vertical disc filter comprises: filter disc 1, time relay 2, motorised valve 3, bellows 4, filter disc 1 includes fan-shaped filter plate 5 and hollow shaft 6, and fan-shaped filter plate 5 circumference sets up and forms the filter disc on the hollow shaft, installs the filter cloth on the fan-shaped filter plate, and fan-shaped filter plate 5 is driven through the speed reducer transmission by the motor, rotates with certain rotational speed in the semicircular groove, and every rotatory a week all experiences filtration, washing in order, inhales futilely, blows the pine, unloads the sediment, and every rotatory a week all experiences an operation cycle. The hollow shaft 6 is hollow cylindrical, the hollow shaft is hollow, positive pressure suction drying, blowing and cake discharging and negative pressure filtering functions are formed at different positions through rotation and holes in the distribution disc 14, the hollow shaft 6 is formed by welding steel plates, the hollow shaft not only plays a role in supporting the filter disc, but also is a passage for gas and liquid to enter and exit the filter disc.
The distribution plate 14 comprises a stationary plate 8 and a movable plate 7 rotating with the hollow shaft 6, the movable plate and the stationary plate being arranged in a stacked arrangement with overlapping centre lines. The movable disc of the distribution disc is fixed on the shaft neck of the hollow shaft 6 and synchronously rotates with the vertical disc filter. The end face of the movable disc is provided with a circle of small filter chambers 13. The fixed disc does not rotate, a first arc-shaped groove 9, a second arc-shaped groove 10, a third arc-shaped groove 11 and a fourth arc-shaped groove 12 are formed in the end face of the inner side of the fixed disc and are respectively communicated with the connecting pipe on the outer side, the first arc-shaped groove 9 and the second arc-shaped groove 10 are pore passages connected with a vacuum pipeline, and the third arc-shaped groove 11 and the fourth arc-shaped groove 12 are pore passages connected with compressed air.
