The purpose is that when the sewage enters the end of the large partition 102 away from the small partition 103, the sewage will first submerge the large partition 102, and then enter the sand settling chamber after passing through the large partition 102. Only when the sewage submerges the small partition 103 will it enter the next step. A collection box 214 for storing garbage and debris is fixedly installed on one side of a closing plate 213 on the treatment box 101. A dumping plate 201 is also fixedly installed on the closing plate 213, and the angle between the dumping plate 201 and the closing plate 213 is one hundred and twenty degrees.

[0022] like Figures 2 to 5 As shown, a water outlet frame 203 is also fixedly installed on the closing plate 213, and the water outlet frame 203 is arranged in the processing chamber. The water outlet frame 203 consists of a concave frame and a bottom pipe. The concave frame of the water outlet frame 203 is provided with a plurality of water filtering holes, and the water filtering holes are used to block the debris in the sewage. The outlet of the bottom pipe on the water outlet frame 203 is arranged outside the processing chamber to allow the filtered sewage to flow out of the processing chamber. A float 202 is slidably installed on the inner wall of the water outlet frame 203, and two protruding rods are also arranged on the float 202. The protruding rods are in sliding contact with the inner wall of the water outlet frame 203, and the end of the protruding rod away from the float 202 is arranged outside the water outlet frame 203.

[0023] like Figures 2 to 6As shown, a collecting device 206 is slidably installed on the outer wall of the concave frame of the water outlet frame 203, and a collecting groove is arranged in the collecting device 206. One end of the collecting device 206 contacts the closing plate 213, and a plurality of slide slot plates 104 for limiting are arranged on the outer side of the collecting device 206.

The card block 216 blocks the collecting device 206, and the card block spring 217 is in a stretched state in the initial state, and the protruding rod on the float 202 blocks the protruding card block 216, so that the protruding card block 216 cannot move away from the collecting device 206. After the water filter hole on the water outlet frame 203 is blocked, the sewage in the treatment box 101 will accumulate, and the sewage will drive the float 202 to slide in the water outlet frame 203, and the float 202 will move away from the protruding card block 216. When the float 202 moves, the float 202 will drive the protruding rod to move, so that the protruding rod is out of contact with the protruding card block 216, and then the protruding card block 216 will be pulled by the card block spring 217, so that the protruding card block 216 will be out of contact with the collecting device 206, allowing the collecting device 206 to enter a movable state.

[0024] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a plurality of support shafts 208 are fixedly installed on the outside of the collecting device 206, and a bracket 210 is also fixedly installed in the processing box 101, and the bracket 210 is fixedly connected to the closing plate 213. An arc-shaped support portion is provided at one end of the bracket 210 away from the support shaft 208, and a semicircular groove 215 is also provided at one end of the bracket 210 provided with the arc-shaped support portion, and the semicircular groove 215 can be matched with the support shaft 208. A roller 207 is rotatably installed on the outside of the collecting device 206. When the roller 207 contacts the arc-shaped support portion on the bracket 210, the roller 207 can support the collecting device 206 to rotate, and when the roller 207 contacts the arc-shaped support portion on the bracket 210, the support shaft 208 will also contact the semicircular groove 215, and at this time, the axis center of the support shaft 208 is the rotation axis center of the collecting device 206.

[0025] like Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, a main shaft 212 is rotatably installed on the outer wall of the processing box 101, and a cleaning motor is also fixedly installed on the outer wall of the processing box 101. The output shaft of the cleaning motor is fixedly connected to the main shaft 212, and the cleaning motor is used to drive the main shaft 212 to rotate. A plurality of winches 211 are fixedly installed on the main shaft 212, and an upper steel cable 209 is provided on the winch 211. The other end of the upper steel cable 209 is fixedly connected to the outer wall of the collecting device 206, and the upper steel cable 209 is slidably connected to the arc-shaped supporting portion on the bracket 210. A lower rotating shaft 205 is also rotatably installed in the processing box 101, and a lower steel cable 204 is provided on the lower rotating shaft 205. The other end of the lower steel cable 204 is fixedly connected to the outer wall of the collecting device 206, and a restoring torsion spring is fixedly installed on the lower rotating shaft 205. The other end of the restoring torsion spring is fixedly installed on the processing box 101. On the inner wall, when the cleaning motor starts to drive the main shaft 212 to rotate, the main shaft 212 drives the winch 211 to rotate, and the winch 211 pulls the collecting device 206 to move on the outer wall of the water outlet frame 203 through the upper steel cable 209, so that the collecting device 206 is used to clean the debris blocking the water filter hole on the outer wall of the water outlet frame 203, and then the collecting device 206 moves away from the water surface with these debris. After the support shaft 208 on the collecting device 206 contacts the semicircular groove 215, the collecting device 206 will rotate around the axis of the support shaft 208, and at this time, the roller 207 on the collecting device 206 will support the collecting device 206 when the collecting device 206 rotates, so that the collecting device 206 rotates until the collecting device 206 contacts the dumping plate 201, and the collecting device 206 will pour the debris in the collecting tank into the collection box 214.

[0026] Working principle: This device precipitates large particles of sediment in the sewage through the large partition 102 and the small partition 103 on the treatment box 101, and the sewage then flows out of the device through the water filter holes on the water outlet frame 203. Some debris that do not pass through the water filter holes will stay on the outside of the water outlet frame 203 until the water filter holes on the water outlet frame 203 are gradually blocked by these debris. Then the sewage will accumulate in the treatment box 101, and the water level of the sewage will gradually increase until the sewage drives the float 202 to move. After the float 202 moves, the protruding block 216 will be separated from the collection device 206, and then the cleaning motor will be started to rotate the main shaft 212, and then the collection device 206 will be driven by the upper steel cable 209 to clean the debris on the outer wall of the water outlet frame 203. The debris is collected by the collecting device 206 through the collecting groove, and then the debris is poured into the collecting box 214 by gravity. The restoring torsion spring on the lower rotating shaft 205 will drive the lower steel cable 204, so that the lower steel cable 204 pulls the collecting device 206 back to the initial position. After cleaning the debris outside the water outlet frame 203, the water level in the processing box 101 will gradually drop. If there are a lot of debris, the cleaning motor can be started several times to make the collecting device 206 perform multiple reciprocating motions. It is worth noting here that the water level gradually drops, and the collecting device 206 needs to return to the initial position before the buoy 202, so as to avoid the protruding block 216 from being stuck, resulting in the protruding block 216 being unable to block the collecting device 206.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
