Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning, in particular to a circulating filtering device in a cleaning and sewage suction vehicle. Background Art

[0002] In urban sewage treatment, sewage suction trucks are an important part of sewage treatment. Their main function is to suck, transport and discharge sludge, feces, etc. from sewers, rainwater wells, inspection wells, septic tanks and various ditches.

[0003] When using a sewage suction truck, first suck the sewage into the sewage tank, stop the operation, and then use a high-pressure water pump to clean the sewage. When using a sewage suction truck to suck sewage, the sewage entering the sewage tank will be filtered through multiple filters. At the same time, because the sewage suction truck has to filter the stains in the sewage for a long time, the stains in the sewage will be filtered out during the filtration process. Part of it will be filtered down, and part will be attached to the filter. As the amount of filtered sewage increases, more and more stains will be attached to the filter. The filter efficiency will be reduced due to the attachment of stains. Therefore, we provide a cleaning and internal circulation filter device in the sewage suction truck. Utility Model Content

[0035] A specific application of this embodiment is: when a sewage suction truck is used for sewage treatment, the sewage is discharged into the sewage tank 11 through the water inlet pipe 14, and the sewage first passes through the filter screen 17 for the first filtration, wherein the filter screen 17 filters out the larger stains in the sewage. When there are too many stains in the filter screen 17, the filter screen 17 can be taken out through the handle 16 for cleaning, and then put back for continued use after cleaning. The sewage passes through the first filtration of the filter screen 17, and then passes through the second filtration of the filter screen 21, and then passes through the filter screen 2. The stains on the filter 21 will remain at the bottom of the sewage tank 11. The sewage that passes through the second filter 21 will pass through the third filter 22 for a third filtration. The stains that cannot pass through the third filter 22 will remain at the bottom of the sewage tank 11 between the second filter 21 and the third filter 22.

When the filter 21 and the third filter 22 need to be sieved, the water in the upper layer will be clear and drawn out through the outlet pipe 15. When the filter screen 3 22 is cleaned, the motor 25 is started to drive the rotating rod 1 335 to rotate, and the rotating rod 1 335 rotates to drive the connecting block 334 to rotate. When the connecting block 334 rotates, the fixed block 2 333 rotates together, and the fixed block 2 333 rotates to drive the coupling rod 332 to rotate.

The dirt in the filter screen 21 and the filter screen 3 22 is vibrated to the bottom of the sewage tank 11. At the same time, a plurality of holes are designed at the bottom of the sewage tank 11 for cleaning the dirt at the bottom of the sewage tank 11. When sewage filtering is performed, the hexagonal head 41 can be rotated to rotate the valve stem 42, and the butterfly plate 43 further blocks the holes. When it is not in use and the bottom of the sewage tank 11 needs to be cleaned, the hexagonal head 41 is rotated to open the butterfly plate 43, and the inside of the sewage tank 11 is flushed and cleaned through the water inlet pipe 14, thereby achieving the effect of cleaning the inside of the sewage tank 11.
