DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a leachate treatment device for hazardous waste disposal, comprising:

[0025] A filter body 1, a water pump 5 is fixedly installed on one side of the filter body 1, a discharge pipe 3 is fixedly connected to the input end of the water pump 5, a connecting pipe 4 is fixedly connected to the output end of the water pump 5, and the connecting pipe 4 is fixedly connected to the filter body 1. The filter body 1 is a prior art and can fully filter the waste liquid. The working principle is similar to the first filter, the second filter and the third filter in a leachate treatment device for hazardous waste disposal with application number CN202221156050.5;

[0026] The filter assembly includes a box body 2, a filter frame 7, a cylinder 9 and a filter screen plate 10. A liquid inlet pipe 6 is provided at the top end of one side of the box body 2, and a liquid discharge pipe 3 is provided at the bottom end of the other side of the box body 2. The filter frame 7 is slidably arranged against the inner wall of the box body 2 and has a certain sealing performance. A support plate 8 is fixedly arranged at the top of the filter frame 7. The cylinder 9 is fixedly installed on the inner top of the box body 2. The output end of the cylinder 9 is fixedly arranged on the top of the support plate 8, so that the cylinder 9 can drive the filter frame 7 to move up and down through the support plate 8;

[0027] The filter screen plate 10 is fixedly arranged on the inner wall of the filter frame 7, and a window 11 is provided on one side of the filter frame 7. The filter screen plate 10 and the window 11 are arranged in cooperation with each other so that the upper surface of the filter screen plate 10 is flush with the inner bottom of the window 11, so that the garbage residue can be discharged. A slag discharge port 12 is provided on one side of the box body 2, and the window 11 and the slag discharge port 12 are arranged in cooperation with each other so that the window 11 can be flush with the slag discharge port 12, and the garbage residue can be discharged from the window 11 and the slag discharge port 12. When the window 11 and the slag discharge port 12 are staggered, the box body 2 and the filter frame 7 can block the window 11 and the slag discharge port 12 respectively. A guide plate 13 is fixedly arranged on one side of the box body 2. The guide plate 13 is inclined. The guide plate 13 and the slag discharge port 12 are arranged in cooperation with each other so that the garbage residue can fall on the guide plate 13 after being discharged from the slag discharge port 12, so as to guide the garbage residue.

[0028] The cleaning component also includes a scraper 14 and a brush 15. The scraper 14 and the brush 15 are both arranged in the filter frame 7. The scraper 14 is slidably arranged against the upper surface of the filter screen plate 10, so that the garbage residue on the filter screen plate 10 can be pushed. The brush 15 is slidably arranged against the lower surface of the filter screen plate 10, so that the garbage residue stuck in the filter screen plate 10 can be swept out. The scraper 14 and the brush 15 are staggered and matched. When discharging the garbage residue, the brush 15 is always located in front of the scraper 14, so that the brush 15 can first sweep out the garbage residue in the filter screen plate 10, and the scraper 14 then pushes out the garbage residue on the filter screen plate 10, so that the garbage residue can be cleaned more fully.

[0029] A guide rod 16 is fixedly provided on one side of the scraper 14 and the brush 15, and the two guide rods 16 are slidably arranged through the filter frame 7. A sliding hole 19 is penetrated on one side of the box body 2, and the two guide rods 16 are movably arranged through the sliding hole 19. A limit plate 17 is fixedly provided on the outer end of the two guide rods 16, and a handle 18 is fixedly provided on the outer side of the limit plate 17. An anti-slip sleeve is fixedly provided on the handle 18 for easy use.

[0030] The detailed working process of the utility model is as follows:

[0031] 1. When in use, the staff first transports the waste liquid from the liquid inlet pipe 6 to the box body 2, and then drops it onto the filter screen plate 10 in the filter frame 7. The filter screen plate 10 filters the garbage residue in the waste liquid, and the filtered waste liquid falls into the inner bottom of the box body 2. The water pump 5 draws the waste liquid in through the discharge pipe 3, and then transports the waste liquid to the filter body 1 through the connecting pipe 4 for sufficient filtering treatment;

[0032] 2. After use, the staff drives the support plate 8 and the filter frame 7 upwards through the cylinder 9 to align the window 11 with the slag discharge port 12, and then pushes the limit plate 17 inwards through the handle 18. The limit plate 17 pushes the scraper 14 and the brush 15 to the other side through the two guide rods 16. The brush 15 sweeps out the garbage residue stuck in the filter screen plate 10, and the scraper 14 pushes the garbage residue on the filter screen plate 10 toward the window 11, so that the garbage residue can be discharged through the slag discharge port 12. Finally, the scraper 14 and the brush 15 are pulled back to their original positions through the handle 18, and the filter frame 7 is driven downward to reset by the cylinder 9, and the filtering operation can be continued.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
