[0014] The present invention provides a municipal sewer sludge treatment device, which has the following beneficial effects:

[0015] (1) The invention, through the setting of the feeding device, can push the sludge to flow in the feeding port by rotating the first motor, the first rotating disk, the crank rod, the sliding rod, and the dredging rod to avoid sludge accumulation and blockage. At this time, the sludge will enter the fixed cylinder, and the sludge in the fixed cylinder will be gradually discharged into the tank body by rotating the first disk and the spiral rod. When the sludge enters the tank body, it will be broken up by the rotation of the cutting rod. The breaking up of the sludge can reduce the size of the sludge particles, thereby improving the dewatering performance of the sludge and reducing the water content of the sludge. The sludge will enter the tank through the fixed cylinder, and the knocking rod will contact the outer wall of the fixed cylinder and generate vibration by rotating the second motor, the second rotating disk, the fixed frame, and the sliding frame. This vibration can help the sludge flow better, especially when the sludge fluidity is poor.

[0016] (2) The invention, through the setting of the dosing device, enables the filter plate to move up and down reciprocatingly through the movement of the arc rod. After the sludge is input into the tank body, it will be on the top of the filter plate. The sludge after filtering the water can be discharged through the discharge port. The up and down reciprocating movement of the sludge on the filter plate can increase the contact area between the sludge and the filter plate, thereby improving the filtration efficiency. This method can make the water in the sludge pass through the filter plate faster, reduce the filtration time, and improve the treatment efficiency. By adding the agent to the dosing port, the agent is transported to the medicine box, and the mixing plate is rotated through the filter plate and the screw rod. The rotation of the mixing plate causes the agent in the medicine box to be broken up, thereby preventing the agent from agglomerating and affecting the combination efficiency with the sewage. After the agent is broken up, it is discharged through the medicine box and mixed with the sewage.

[0017] (3) The invention, through the setting of the stirring device, drives the scraper to rotate through the stirring rod, connecting rod, gear, gear block frame and round rod. The rotation of the scraper contacts the inside of the tank body so that the impurities remaining in the tank body are scraped off. The scraper can help remove the dirt and sediment on the inner wall of the tank body. These substances may hinder the water flow and reduce the sewage treatment efficiency. The rotation of the stirring rod drives the stirring blade to rotate. The stirring blade makes the agent and sewage fully mixed, thereby improving the sewage treatment efficiency. The stirring rod, rotating rod and reciprocating spiral groove make the stirring rack move up and down. The movement of the stirring rack makes the solid particles settled at the bottom of the inner wall of the tank body be drained into the working range of the stirring blade. During the stirring process, due to the effect of gravity, the sediment often gathers at the bottom of the inner wall of the tank body. By draining the sediment, the sediment can be better mixed with other materials, improving the uniformity of stirring. The output of the treated sewage is controlled by the liquid outlet valve.

The movement of the knocking rod 114 will contact the outer wall of the fixed cylinder 10 and generate vibration. This vibration can help the sludge flow better, especially when the sludge fluidity is poor. The rotation of the rotating disk 111 drives the disc 19 to rotate, and the rotation of the disc 19 drives the arc rod 115 to move.

One side of the filter plate 20 is slidably mounted on the inner wall of the tank body 2, and the other side of the filter plate 20 is rotatably mounted on the bottom of the arc rod 115. The discharge port 21 is arranged on the front side of the tank body 2, and the cross 22 is fixedly mounted on the inner wall of the tank body 2.

This method can make the moisture in the sludge pass through the filter plate 20 faster, reduce the filtration time, and improve the processing efficiency.

[0031] The dosing device also includes a medicine box 23 and a dosing port 24. The medicine box 23 is fixedly installed on the inner wall of the cross 22.

[0036] When the present embodiment is working, the filter plate 20 is moved up and down reciprocatingly by the movement of the arc rod 115. After the sludge is input into the tank body 2, it will be at the top of the filter plate 20. The sludge after filtering water can be discharged through the discharge port 20. The up and down reciprocating movement of the sludge on the filter plate 20 can increase the contact area between the sludge and the filter plate 20, thereby improving the filtering efficiency. This method can make the water in the sludge pass through the filter plate 20 faster, reduce the filtering time, and improve the processing efficiency. By adding the agent to the dosing port 24, the agent is transported to the medicine box 23, and the filter plate 20 moves downward and the screw rod 25 moves downward.

The rotation of the round rod 36 drives the scraper 37 to rotate. The rotation of the scraper 37 contacts the inside of the tank body 2 so that the impurities remaining in the tank body 2 are scraped off. The scraper 37 can help remove the dirt and sediment on the inner wall of the tank body 2. These substances may hinder the water flow and reduce the sewage treatment efficiency. The rotation of the stirring rod 27 drives the stirring blade 32 to rotate. The stirring blade 32 allows the medicine and the sewage to be fully mixed. The mixing improves the efficiency of sewage treatment. The rotation of the stirring rod 27 drives the rotating rod 33 to rotate, and the rotation of the rotating rod 33 drives the reciprocating spiral groove to rotate. The reciprocating spiral groove rotates to make the stirring rack 34 move up and down. The solid particles settled at the bottom of the inner wall of the tank body 2 are drained into the working range of the stirring blade 32 through the movement of the stirring rack 34. During the stirring process, due to the effect of gravity, the sediment often gathers at the bottom of the inner wall of the tank body 2. By draining the sediment, the sediment can be better mixed with other materials, thereby improving the uniformity of stirring. The output of the treated sewage is controlled by the liquid outlet valve 3.
