[0002] The mud press is one of the commonly used equipment in sewage treatment projects. It is used to treat sludge. The working principle of the sewage treatment mud press is to squeeze out the water in the sludge through mechanical pressure, thereby reducing the volume of the sludge, increasing the solid content, and making the sludge easier to handle and dispose of.

[0003] The existing technology of sewage treatment mud press generally puts the sludge into the inside of the mud press box, and then uses the squeezing plate to squeeze the sludge so that the water inside the sludge is squeezed out, and the squeezed out water drips through the filter screen or filter cloth. However, since the mesh of the filter screen or filter cloth is designed to be small in order to prevent the soil from falling, the water is easy to adhere to the filter cloth and cannot drip in a short time, resulting in reduced mud pressing efficiency. At the same time, when the mud blocks need to be taken out after the mud pressing process is completed, the sludge is easy to adhere to the inner wall of the mud press box after being squeezed, and the staff needs to use external tools to take it out, which is very troublesome, time-consuming and labor-intensive, which affects the mud pressing progress of the subsequent sludge and further reduces the mud pressing efficiency.

[0024] Specifically, the transmission assembly includes a motor 11 and a transmission unit. The motor 11 is fixedly connected to the outer side of the support frame 2. The inner side of the support frame 2 is rotatably connected to a lead screw 12. The outer sides of the lead screw 12 are provided with threads on both sides close to the push plate 4. The two groups of mud pressing boxes 3 are rotatably connected to the lead screw 12. The two groups of push plates 4 are threadedly connected to the lead screw 12 through threads. The inner side of the support frame 2 away from the lead screw 12 is fixedly connected to a limit rod 13. The two groups of push plates 4 are slidably connected to the limit rod 13. The hammer assembly can hammer the mud pressing box 3 through the transmission unit. The transmission unit includes a rack 14. The rack 14 is fixedly connected to the lower sides of the outer sides of the push plate 4. The lower sides of the outer sides of the mud pressing box 3 are fixedly connected to limit blocks. The rack 14 is slidably connected to the inside of the limit blocks. The outer side of the support frame 2 L-shaped plates 8 are symmetrically fixedly connected on both sides close to the mud press box 3, and a gear 15 is rotatably connected to the top of the L-shaped plate 8 on the side away from the limit plate 9. The gear 15 is meshed with the rack 14, and the hammer assembly includes a turntable 16, which is fixedly connected to the top of the gear 15, and a connecting rod 17 is rotatably connected to one side of the top of the turntable 16.

The two second rotating plates 21 are rotatably connected to the hammer 10 at one end away from the first rotating plate 19, and a spring 20 is arranged between the two first rotating plates 19.

[0025] Through the above technical scheme, the sludge is injected into the mud press box 3 through the feed port, and then the motor 11 is started through the external controller. The output end of the motor 11 drives the lead screw 12 to rotate, so that the lead screw 12 drives the two sets of push plates 4 to move toward the corresponding mud press box 3 through the threaded connection relationship, so that the push plate 4 drives the pressure plate 5 to squeeze the sludge inside the mud press box 3, and squeezes out the water in the sludge. The squeezed water falls into the collection tank 1 through the filter plate 7. During the movement of the push plate 4, the rack 14 can be driven to move, so that the gear 15 is driven to rotate through the meshing relationship between the rack 14 and the gear 15, so that the gear 15 drives the top turntable 16 to rotate, thereby The turntable 16 drives the connecting rod 17 to push the hammer 10, so that the hammer 10 hammers the mud pressing box 3, thereby increasing the speed of water falling and preventing part of the squeezed water from adhering to the bottom of the mud pressing box 3 or the outside of the filter plate 7 during the mud pressing process and failing to drip in a short time, thereby reducing the mud pressing efficiency. During the continuous rotation of the turntable 16, the hammer 10 can be pushed to repeatedly hammer the mud pressing box 3, thereby increasing the vibration frequency of the mud pressing box 3 and ensuring the hammering effect. The hammer 10 can improve the striking effect of the mud pressing box 3 through the cooperation of the two sets of first rotating plates 19 and the second rotating plates 21 and the spring 20. After the water in the sludge is completely squeezed, the push plate 4 is driven The push plate 4 drives the rack 14 to move again, and the mud box 3 can be hammered again by the hammer assembly, and the mud blocks squeezed into blocks inside the mud box 3 can be vibrated, so that a gap is generated between the mud blocks and the inner wall of the mud box 3. Then the box door 6 is opened, and the mud blocks can naturally fall to the top of the screen frame 22, which is convenient for removing the mud blocks and preventing the mud from adhering to the inner wall of the mud box 3 after being squeezed, making it inconvenient to remove the mud blocks. In the process of squeezing the mud by the pressure plate 5, the hammer 10 can perform high-frequency hammering on the mud box 3, causing the mud box 3 to vibrate violently, thereby The speed of water falling during the mud pressing process is increased to prevent part of the pressed water from adhering to the bottom of the mud pressing box 3 or the outside of the filter plate 7 during the mud pressing process, and being unable to drip in a short time, thereby reducing the mud pressing efficiency. At the same time, after the mud pressing is completed, the pressing plate 5 moves toward the outside of the mud pressing box 3, so that the hammer 10 performs high-frequency hammering on the mud pressing box 3, which can vibrate the mud blocks squeezed into blocks inside the mud pressing box 3, so that a gap is generated between the mud blocks and the inner wall of the mud pressing box 3, and then the box door 6 is opened, and the mud blocks can naturally fall to the top of the screen frame 22, which facilitates the removal of the mud blocks and prevents the sludge from adhering to the inner wall of the mud pressing box 3 after being squeezed, making it inconvenient to remove the mud blocks.

[0030] When in use, the sludge is injected into the mud pressing box 3 through the feed port, and then the motor 11 is started through the external controller. The output end of the motor 11 drives the lead screw 12 to rotate, so that the lead screw 12 drives the two sets of push plates 4 to move toward the corresponding mud pressing box 3 through the threaded connection relationship, so that the push plate 4 drives the pressing plate 5 to squeeze the sludge inside the mud pressing box 3, and squeeze out the water in the sludge. The squeezed water falls into the inside of the collection tank 1 through the filter plate 7. During the movement of the push plate 4, the rack 14 can be driven to move, so that the rack 14 and the gear 15 are connected.

After the water in the sludge is completely squeezed, the push plate 4 is driven to move back to the original position, thereby driving the pressing plate 5 to move to the outside of the mud pressing box 3. At the same time, the push plate 4 drives the rack 14 to move again, and the mud pressing box 3 can be hammered again by the hammering assembly, and the mud blocks squeezed into blocks inside the mud pressing box 3 can be vibrated, so that a gap is generated between the mud blocks and the inner wall of the mud pressing box 3, and then the box door 6 is opened, and the mud The mud blocks can naturally fall to the top of the screen frame 22, which is convenient for removing the mud blocks and prevents the sludge from adhering to the inner wall of the mud pressing box 3 after being squeezed, making it inconvenient to remove the mud blocks. The provided buffer pad can prevent the hammer 10 from causing damage to the mud pressing box 3 during the hammering process of the mud pressing box 3.
