[0027] A sludge discharge device for sewage treatment includes a box body 1, a drain pipe 2 fixedly connected to the bottom end of the side of the box body 1, and a water inlet pipe 5 fixedly connected to the side of the box body 1 away from the drain pipe 2.

[0028] In this implementation: The existing publication (announcement) number: CN218810901 discloses a sludge discharge device for sewage treatment; to solve the technical problems existing in this prior art, such as those disclosed in the background art above, "when treating sludge, the sludge is pushed and cleaned by a push plate, the cleaning effect is poor, some sludge is likely to remain on the surface of the filter screen, affecting the subsequent filtration effect, and at the same time, the treatment of sewage stops during cleaning, which will reduce the efficiency of sewage treatment". In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a filtering component 3 and a cleaning component 4 are added to this application document.

[0029] Furthermore:

[0030] As Figures 1 - 4 shown:

[0031] Combined with the above content, the filtering component 3 includes a conveyor belt 33 installed inside the box body 1 and inclined, a filter screen 34 is fixedly connected to the surface of the conveyor belt 33, a sludge storage tank 31 is fixedly connected to the side of the box body 1, and the upper side of the conveyor belt 33 is located inside the sludge storage tank 31. A motor 35 is installed on the side of the sludge storage tank 31 close to the conveyor belt 33, and the output end of the motor 35 is connected to the drive shaft of the conveyor belt 33. A number of cleaning rollers 36 are rotatably connected to the side of the sludge storage tank 31 close to the filter screen 34.

[0032] In this implementation: When treating sewage, first, the sewage mixed with flocculant is transported to the inside of the box body 1 through the water inlet pipe 5. When the sewage passes through the filter screen 34, the sewage is separated from the sludge. The separated sewage is discharged through the drain pipe 2, and the separated sludge is blocked on the surface of the filter screen 34. Then, the cleaning rollers 36 are started, and the conveyor belt 33 drives the filter screen 34 to transport the sludge, and the sludge is transported to one side of the sludge storage tank 31 and is cleaned by the cleaning rollers 36 and falls into the sludge storage tank 31. The conveyor belt 33 is inclined, so that the sewage inside the box body 1 is not easy to enter one side of the sludge storage tank 31 and will not affect the normal progress of sewage treatment.

[0033] Even further:

[0034] As Figures 1 - 4 shown:

[0035] In an alternative embodiment to improve the cleaning effect of the sludge on the surface of the filter screen 34: The cross-section of the filter screen 34 is wavy; a sludge discharge pipe 32 is fixedly connected to the side of the sludge storage tank 31; a sprocket 37 is fixedly connected to the top of the cleaning roller 36, a chain 38 is meshed with the surface of the sprocket 37, a motor 39 is fixedly connected to the side of the sludge storage tank 31, the output end of the motor 39 is fixedly connected to a sprocket 310, and a number of sprockets 37 are connected to the sprocket 310 through the chain 38

[0036] In this embodiment, when the conveyor belt 33 conveys the sludge, starting the second motor 39 can drive the second sprocket 310 to rotate, and then drive a plurality of first sprockets 37 to rotate synchronously through the chain 38, thereby driving the cleaning roller 36 to rotate, improving the cleaning effect of the cleaning roller 36 on the sludge on the surface of the filter screen 34. The cleaned and fallen sludge will be discharged through the sludge discharge pipe 32.

[0037] It should be noted that: the surface of the cleaning roller 36 is fixedly connected with cleaning brushes arranged in an annular array. The sludge on the surface of the filter screen 34 is cleaned by the rotation of the cleaning roller 36. The first motor 35, the cleaning roller 36, and the water pump 41 are all electrically connected to an external power source through wires.

[0038] Furthermore:

[0039] As Figures 1 - 4 shown:

[0040] Combined with the above content, a cleaning component 4 is arranged inside the box body 1. The cleaning component 4 includes a flow dividing pipe 42 fixedly connected to the top end inside the box body 1 and having a frame structure. A number of washing nozzles 43 are fixedly connected to the surface of the flow dividing pipe 42. A water pump 41 is fixedly connected to the top end of the box body 1, and the output end of the water pump 41 is connected to the washing nozzles 43.

[0041] In this implementation scheme, after the sewage treatment, sludge will adhere to the inner wall of the box body 1. The input end of the water pump 41 is externally connected to a water source, and then the water pump 41 is started to convey the water flow into the flow dividing pipe 42 and spray out from the washing nozzles 43. The residual sludge on the inner wall of the box body 1 is washed by the washing nozzles 43, preventing the sludge from accumulating inside the box body 1 and affecting the normal use of the device.

[0042] Working principle: When performing sewage treatment, first, the sewage mixed with the flocculant is conveyed into the box body 1 through the water inlet pipe 5. When the sewage passes through the filter screen 34, the sewage is separated from the sludge. The separated sewage is discharged through the drain pipe 2, and the separated sludge is blocked on the surface of the filter screen 34. Then, the cleaning roller 36 is started, and the filter screen 34 is driven by the conveyor belt 33 to convey the sludge. The sludge is conveyed to one side of the sludge storage tank 31. Subsequently, starting the second motor 39 can drive the second sprocket 310 to rotate, and then drive a plurality of first sprockets 37 to rotate synchronously through the chain 38, thereby driving the cleaning roller 36 to rotate. The sludge on the surface of the filter screen 34 is cleaned by the cleaning roller 36. The finally cleaned and fallen sludge will be discharged through the sludge discharge pipe 32. After the sewage treatment, sludge will adhere to the inner wall of the box body 1. The input end of the water pump 41 is externally connected to a water source, and then the water pump 41 is started to convey the water flow into the flow dividing pipe 42 and spray out from the washing nozzles 43. The residual sludge on the inner wall of the box body 1 is washed by the washing nozzles 43.
