Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

Provided by Fig. 1 to Fig. 7, the utility model comprises vertical main pipeline 1, and the coaxial below main pipeline 1 is provided with branch pipeline 2, and the lower end of branch pipeline 2 is connected with horizontal pipeline 3; There is a retaining ring 4, and two outlets 5 are arranged on the retaining ring 4. After the branch pipe 2 drives the transverse pipe 3 to rotate together, the ports of the transverse pipe 3 can correspond to the two outlets 5 respectively;

The lower end of the main pipeline 1 is provided with a main filter plate 6, and the upper end of the branch pipeline 2 is provided with a secondary filter plate 7, and the main filter plate and the secondary filter plate 7 are provided with a filter mesh 8 connected to each other; the main filter plate 6 and the secondary filter plate 7 are connected. The auxiliary filter plate 7 is clearance fit.

In order to realize that the main pipeline 1 and the branch pipeline 2 are connected together, the main pipeline 1 is provided with an installation ring 9, and a plurality of bolts 10 are fixed on the installation ring 9, and the branch pipeline 2 is covered with a ring gear 14, and the teeth of the gear There are arc-shaped relief grooves corresponding to a plurality of bolts 10 on the surface, and the bolts 10 pass through the relief grooves. A washer 11 and a nut 13 are installed on the lower end of the bolt 10, and a spring is connected between the washer 11 and the nut 13. 12; the ring gear 14 is driven by a motor.

In order to realize the cooperation of the main filter plate 6 and the auxiliary filter plate 7, a plurality of filter mesh holes 8 are evenly distributed on the main filter plate 6 and the auxiliary filter plate 7, and the filter screens on the main filter plate 6 and the auxiliary filter plate 7 When the holes 8 correspond to each other, the port of the transverse duct 3 corresponds to one of the outlets 5; when the filter mesh holes 8 on the main filter plate 6 and the secondary filter plate 7 are misaligned, the port of the transverse duct 3 corresponds to the other outlet 5.

In order to facilitate the discharge of filtered water from the slag receiving box, the two outlets 5 are connected with pipes.

In order to realize the disassembly of the main filter plate 6 and the secondary filter plate 7, and the close fit of the two, the ends of the main pipeline 1 and the branch pipeline 2 are provided with sinking tanks, and the main filter plate 6 and the secondary filter plate 7 They are respectively placed in the sinking tanks of the main pipeline 1 and the branch pipeline 2, between the main filter plate 6 and the sinking tank, and between the auxiliary filter plate 7 and the sinking tank are connected with compression springs, the upper end surface of the main filter plate 6 and the auxiliary filter plate 6 Sleeves are arranged on the lower end surfaces of the filter plates 7 .

When the utility model is in use, at first two outlets 5 of the retaining ring 4 need to be connected with pipelines, one of which is a clean water pipeline, and the other pipeline is a slag discharge pipeline.

The device has two devices of filtration and slag discharge, and can correspond to different states through the rotation of the branch pipe 2; The filter holes 8 on the auxiliary filter plate 7 are misaligned with each other, and because the upper and lower filter plates are stacked up and down, when the sewage passes through, the filter aperture will become smaller due to the misalignment of the two filter plates. Small, so that the particles in the sewage are blocked by the two filter plates.

At this time, the port of the horizontal pipe 3 just corresponds to the water purification pipe, that is, the filtered sewage can be smoothly discharged from the water purification pipe.

When slag removal is needed, turn the branch pipeline 2 at this time, so that the filter mesh holes 8 on the secondary filter plate 7 on the branch pipeline 2 are completely corresponding to the filter mesh holes 8 on the main filter plate 6 on the main pipeline 1; The filter mesh holes 8 between the two filter screens completely overlap, and then compared with the time of filtration, the aperture of the filter becomes larger at this time, and the previously blocked particles will pass through the two filter plates, and pass through the branch pipe 2 and the horizontal pipe. 3 discharge. At this time, through the rotation of the branch pipe 2, the outlet 5 of the horizontal pipe 3 just corresponds to the slag discharge pipe, so the sewage containing large particles can be discharged into the slag discharge pipe, and the self-cleaning of the filter plate is also realized.

When the self-cleaning of the slag discharge is completed, the branch pipe 2 can be reset again; in summary, the rapid self-cleaning of the filter plate can be realized by intermittently reciprocating the branch pipe 2; on the one hand, it can save energy , on the other hand, the whole device can also be easily maintained and not easily damaged.

After running for a long time, the main pipeline 1 and the branch pipeline 2 can be cleaned to avoid internal blockage caused by large debris.
