The utility model provides a pollution prevention and control desludging machine, as shown in Figures 1 to 3, including a material bin 1, a material conveying pipe 4 is obliquely arranged inside the material bin 1, a feed pipe 11 is vertically connected to the upper part of the material conveying pipe 4, a sludge bin 2 is connected to one side of the top of the material conveying pipe 4, a water collecting bin 3 is installed at the bottom of the sludge bin 2, a first screw rod 21 is installed inside the sludge bin 2, one end of the first screw rod 21 is driven to rotate by a first motor 22, a pressing plate 23 is installed on the first screw rod 21, a plurality of small holes are arranged on the surface of the pressing plate 23, the sludge is squeezed by the pressing plate 23 to realize water discharge, a drain port 24 is arranged at the bottom of one end of the sludge bin 2, the bottom of the drain port 24 is connected to the water collecting bin 3, a water supply is installed on one side of the bottom of the water collecting bin 3, and an overflow pipe 12 is connected to the outer wall of one side of the material bin 1 for overflowing and discharging water in the sludge.

In this embodiment, a mud inlet 25 is provided at one end of the mud bin 2 , a mud outlet 45 is provided at the top end of the feed pipe 4 , and the mud inlet 25 is connected to the mud outlet 45 .

Specifically, a material taking port 26 is provided at the top of one end of the sludge bin 2, and a sealing plug is installed at the material taking port 26 to facilitate taking out the squeezed sludge.

Furthermore, a threaded hole is provided in the middle of the pressing plate 23, and the first screw rod 21 is threadedly connected to the threaded hole, so that the first screw rod 21 can drive the pressing plate 23 to move, squeeze the sludge, squeeze out water, and form a mud cake structure.

Furthermore, a second screw rod 41 is provided inside the feed pipe 4, a spiral push piece 42 is installed outside the second screw rod 41, one end of the second screw rod 41 is driven to rotate by a second motor 43, an overflow port 44 is provided on one side of the upper part of the feed pipe 4, and a feed port 46 is also provided on the upper part of the feed pipe 4, and the feed port 46 is connected to the bottom end of the feed pipe 11.

Furthermore, the height of the overflow port 44 is flush with the height of the overflow pipe 12 , and the height of the feed port 46 is higher than the height of the overflow port 44 .

Furthermore, a sand outlet 47 is provided on the bottom lower surface of the feed pipe 4 , and a mesh plate is installed on the inner side of the sand outlet 47 to facilitate the discharge of sand. The height of the sand outlet 47 is higher than that of the feed port 46 to prevent water from overflowing from the sand outlet 47 .

Furthermore, a water-blocking baffle is installed between the second screw rod 41 and the second motor 43 to prevent water from entering the second motor 43 .

When the pollution prevention and control desludging machine of the utility model is used, the sludge to be treated is first introduced into the conveying pipe 4 through the feeding pipe 11. Inside the conveying pipe 4, the second motor 43 drives the second screw 41 to rotate, thereby driving the spiral push piece 42 to rotate, and the sludge is evenly pushed toward the sludge bin 2. When the sludge is pushed to the sludge bin 2, the first motor 22 is started to drive the first screw 21 to rotate. Since the pressing plate 23 is threadedly connected to the first screw 21, the pressing plate 23 will move along the axial direction of the first screw 21 to squeeze the sludge. During the squeezing process, the moisture in the sludge is squeezed out through the small holes on the surface of the pressing plate 23, and flows into the water collection bin 3 through the drain port 24, and is finally discharged through the water delivery pipe. At the same time, an overflow port 44 is provided at the upper part of the conveying pipe 4. When there is too much moisture in the sludge, it will overflow through the overflow port 44 and be discharged through the overflow pipe 12, thereby ensuring the stable operation of the equipment. In addition, a sand outlet 47 is provided at the bottom of the feed pipe 4, and a mesh plate is installed inside so as to discharge impurities such as sand during the sludge treatment process. After the sludge is fully squeezed, a mud cake structure with low water content is formed. At this time, the mud cake can be taken out through the material taking port 26 for subsequent treatment or disposal. During the entire treatment process, the equipment realizes efficient and environmentally friendly treatment of sludge and avoids the generation of secondary pollution.
