Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example (b): a drum filter, as shown in figures 1-3, comprises a box 1, a water pump 2, a drum 3, a brush 4, a water absorbing device 5 and a water spraying pipe 6. Wherein, the box body 1 is provided with a sewage inlet, and sewage in the fabric cleaning equipment enters the box body 1 from the sewage inlet; the water pump 2 is provided with a water inlet and a water outlet.

Meshes are uniformly arranged on the surface of the rotary drum 3 to form a cylindrical filter screen, sewage is arranged on the outer side of the rotary drum 3, and filtered clean water is arranged on the inner side of the rotary drum 3; brush 4 is cylindrical, and the setting of next-door neighbour rotary drum 3 passes through chain drive between the pivot of rotary drum 3 and brush 4 to the rotation of the two is by same motor drive, and the direction of rotation is the same, is used for increasing the relative rotational speed between brush 4 and the rotary drum 3, promotes brush hair efficiency.

In this embodiment, brush 4 sets up in the oblique top of rotary drum 3, and the contact point department of brush 4 and rotary drum 3 is provided with flock collection board 7, and flock collection board 7 sets up along the 3 tangential direction slope of rotary drum, and its one side of keeping away from brush 4 extends to the outside of box 1 to be provided with cover plate 8 above flock collection board 7, form flock discharge passage between cover plate 8 and the flock collection board 7, its one side for being provided with flock collection board 7 with the moving direction of the contact point of rotary drum 3 when brush 4 rotates. When the brush 4 and the rotary drum 3 rotate relatively, the brush 4 brushes down the flock on the outer surface of the rotary drum 3 and collects the flock on the flock collecting plate 7, and then the flock is discharged out of the box body 1 through a channel between the cover plate 8 and the flock collecting plate 7.

The water absorption device 5 is arranged on the inner side of the rotary drum 3 and comprises a water absorption pipe 51 and two side plates 52, the water absorption pipe 51 is arranged along the length direction of the rotary drum 3, a strip-shaped notch is arranged on the lower portion of the water absorption pipe 51 along the axial direction, the two side plates 52 are respectively arranged on two sides of the notch and extend downwards to the position close to the inner surface of the lower portion of the rotary drum 3 to form a strip-shaped water absorption port, one side of the two side plates 52 far away from the water absorption pipe 51 inclines outwards slightly to form a horn shape, and the. The water suction pipe 51 is communicated with a water inlet of the water pump 2, when the water pump 2 works, clean water on the inner side of the rotary drum 3 is pumped out through the water pump 2 through a strip-shaped water suction port formed by the two side plates 52, and the clean water is circularly conveyed to the cleaning equipment through a water outlet of the water pump 2 for cyclic utilization. The bar-shaped water suction port increases the adsorption force of the flocks in the water suction process, so that the flocks in the sewage can be adsorbed on the surface of the rotary drum 3 in a large amount, and the flock yield is improved. The water sucking port is arranged downwards so as to enable the water sucking position to be as low as possible, the water level in the box body 1 is prevented from influencing the normal work of the water pump 2, and the circulation of the washing liquid can be realized when the water level in the box body 1 is lower.
