[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 and Figure 2 As shown, a sludge dewatering machine for sewage treatment includes a box body 1, a feed hopper is fixedly installed in the middle of the upper end of the box body 1, a water outlet pipe is fixedly installed at the left bottom of the box body 1, a box door is fixedly installed in the middle of the rear side of the box body 1, a drain squeezing assembly 2 is fixedly installed on the right side of the box body 1, a collecting assembly 3 is fixedly installed at the bottom of the drain squeezing assembly 2, and a sewage cleaning assembly 4 is fixedly installed at the left bottom of the box body 1.

[0028] The draining and squeezing component 2 can first pass the sludge with a high water content through the electric conveyor belt 21, and then drain the sludge through the drain holes opened on the outer surface of the electric conveyor belt 21, and then squeeze the sludge, which can effectively prevent the sludge from entering the box 1 with the water. The collection component 3 can collect the remaining sludge without manual processing, and it is convenient for the staff to clean the collection box 31, thereby improving the practicality of the dehydrator. The sewage cleaning component 4 can purify the water source by adding chemical agents to the sewage to prevent the sewage from being released to the outside and affecting the environment.

[0029] like Figure 4 and Figure 5 As shown, the drain squeezing assembly 2 includes an electric conveyor belt 21, and the front and rear parts of the electric conveyor belt 21 are movably connected to the front and rear parts of the inner wall of the box body 1. The electric conveyor belt 21 is located directly below the feed hopper, and a plurality of drain holes are provided on the outer peripheral surface of the electric conveyor belt 21. A discharge trough is provided on the top right side of the box body 1, and an inclined plate 22 is fixedly installed on the bottom of the inner wall of the discharge trough. The upper end of the inclined plate 22 overlaps the outer peripheral surface of the electric conveyor belt 21, and a drain box 23 is fixedly installed on the middle part of the right side of the box body 1, and the drain box 23 is located below the discharge trough.

[0030] Through the transmission action of the electric conveyor belt 21 , the drainage holes opened on its outer peripheral surface drain the sludge with a high water content, and the sludge enters the drainage box 23 through the cooperation between the electric conveyor belt 21 and the inclined plate 22 .

[0031] like Figure 5 As shown, a filter plate 24 is fixedly mounted on the inner wall of the drain box 23, and three water pipes 25 arranged linearly and passing through the right part of the box body 1 are fixedly mounted on the lower end of the drain box 23.

[0032] The sludge carrying moisture is filtered again through the filter plate 24 , and the moisture enters the interior of the box body 1 through three water pipes 25 .

[0033] like Figure 4 and Figure 5 As shown, a motor 26 is fixedly installed on the front right part of the box body 1, and a gear 27 is fixedly sleeved on the output end of the motor 26. A rack 28 is slidably connected to the front top of the drain box 23, and the outer surface of the gear 27 is meshed with the front side of the rack 28. Slide grooves 29 are provided on the front and rear tops of the drain box 23, and the inner walls of the two slide grooves 29 are slidably connected with connecting blocks 210. The front end of the front connecting block 210 is fixedly connected to the rear right part of the rack 28, and push plates 211 are fixedly installed on the opposite ends of the two connecting blocks 210.

[0034] The output end of the motor 26 drives the gear 27 to rotate, and the rack 28 drives the push plate 211 to move by meshing with the rack 28. The push plate 211 pushes the sludge to approach the squeezing plate 214, so that the sludge is squeezed, thereby separating the water from the sludge.

[0035] like Figure 4 and Figure 5 As shown, a mounting bracket 212 is fixedly installed on the bottom right side of the box body 1, and an adjusting screw 213 that passes through the rear part of the mounting bracket 212 is rotatably connected to the top rear side of the mounting bracket 212, and an extrusion plate 214 is fixedly installed on the left end of the adjusting screw 213, and the lower end of the extrusion plate 214 overlaps with the upper end of the filter plate 24, and the left and right sides of the extrusion plate 214 overlap with the front and rear parts of the inner wall of the drain box 23.

[0036] By rotating the adjusting screw 213, the squeezing plate 214 is moved until the drain box 23 is closed, and the cooperation between the squeezing plate 214 and the pushing plate 211 can squeeze out the residual water in the sludge.

[0037] like Figure 5 As shown, telescopic rods 215 are fixedly installed at the front and rear positions of the top right side of the mounting frame 212 , and the output ends of the two telescopic rods 215 are fixedly connected to the front and rear parts of the right side of the extrusion plate 214 .

[0038] The two telescopic rods 215 have a limiting effect on the movement of the extrusion plate 214 .

[0039] like Figure 6 and Figure 7 As shown, the collecting assembly 3 includes a collecting box 31, a through slot is provided at the right bottom of the mounting frame 212, the collecting box 31 is located behind the through slot, the lower end of the collecting box 31 is slidably connected to the bottom of the inner wall of the mounting frame 212, and movable slots 32 are provided at the front and rear right parts of the mounting frame 212, the inner walls of the two movable slots 32 are slidably connected with sliders 33, and the sides of the two sliders 33 that are away from each other are fixedly installed with U-shaped fixing plates 34, and the opposite sides of the two U-shaped fixing plates 34 abut against the front and rear sides of the collecting box 31, and the opposite sides of the two sliders 33 are fixedly installed with two return springs 35, and the opposite ends of the four adjacent return springs 35 are fixedly connected to the sides of the inner walls of the two movable slots 32 that are close to each other.

[0040] The collection box 31 can slide through the through slot into the bottom of the drain box 23. The elastic restoring force of the four adjacent return springs 35 can enable the two U-shaped fixing plates 34 to clamp and fix the collection box 31.

[0041] like Figure 3 As shown, the sewage cleaning component 4 includes a liquid storage tank 41, the right side of the liquid storage tank 41 is fixedly installed on the bottom of the left side of the box body 1, a liquid adding pipe is fixedly installed on the upper end of the liquid storage tank 41, a pump body 42 is fixedly installed on the upper front part of the liquid storage tank 41, and the output end of the pump body 42 passes through the left part of the box body 1.

[0042] The pump body 42 pumps the chemical agent in the liquid storage tank 41 into the tank body 1 to purify the water source in the tank body 1 .

[0043] The working principle of the utility model is as follows: the staff pours the sludge to be dehydrated from the feed hopper in turn, and the sludge falls onto the outer peripheral surface of the electric conveyor belt 21. The excess water falls to the bottom of the inner cavity of the box body 1 through a number of drainage holes. The electric conveyor belt 21 cooperates and scrapes through the inclined plate 22, and the drained sludge moves to the drainage box 23. The motor 26 is started, and the output end of the motor 26 drives the gear 27 to rotate. The rack 28 drives the front connecting block 210 to move by meshing with the gear 27, so that the two connecting blocks 210 move at the same time and drive the push plate 211 to gradually approach the extrusion plate 214. The push plate 211 squeezes the sludge between it and the extrusion plate 214, and the remaining water is filtered by the filter plate 24 and then re-enters the box body 1 through the three water pipes 25.

[0044] Then, the adjusting screw 213 is rotated, and the adjusting screw 213 drives the squeezing plate 214 away from the pushing plate 211 by being threadedly connected with the mounting frame 212, driving the pushing plate 211 to push the dehydrated sludge into the collecting box 31. After the collecting box 31 collects to a certain extent, the two U-shaped fixing plates 34 are pulled to make the four return springs 35 elongated and accumulate elastic potential energy, and the collecting box 31 is released from the fixed state. The staff slides the collecting box 31 out, uniformly handles the dehydrated sludge and quickly cleans the collecting box 31. After the cleaning work is completed, the collecting box 31 is slid back from the through slot to its original position, and the two U-shaped fixing plates 34 are loosened. The elastic restoring force of the four return springs 35 corresponds to the U-shaped fixing plate 34 to reset and fix the collecting box 31.

[0045] Among them, the pump body 42 pumps the chemical agents in the liquid storage tank 41 into the interior of the box body 1, so that the sewage and the chemical agents inside the box body 1 react, and the purified water source is discharged to the outside through the outlet pipe. The staff can open the box door to clean the reaction sediment inside the box body 1 when the dehydrator finishes working.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
