[0002] Sludge dewatering and pressing equipment is a type of equipment used to treat sludge. Its main function is to reduce the moisture content of sludge through physical methods, thereby reducing the volume and weight of the sludge and facilitating subsequent processing or disposal. The pressing equipment usually uses mechanical pressure to squeeze out the water from the sludge, making the sludge drier. This equipment is widely used in sewage treatment plants, sludge treatment plants and other environments, helping to reduce the cost of waste treatment and disposal, while also reducing the impact on the environment.

[0003] Existing pressing devices tend to leave a large amount of sludge residue adhering to the inner wall of the container after pressing. Users need to spend a lot of time cleaning the inside of the container after each pressing, otherwise it will affect the subsequent pressing effect and seriously reduce work efficiency. Utility Model Content

[0004] This utility model aims to provide a sludge dewatering and pressing device with anti-sticking function to solve the problems mentioned in the background art. In this solution, a movable bottom plate is set inside the pressing box. By moving the bottom plate, the sludge in the pressing box can be pushed to the upper side of the pressing box for centralized processing after sludge dewatering. During the process, the bottom plate can scrape off the sludge adhering to the inner wall of the pressing box. Subsequently, the sludge on the bottom plate is discharged by the push plate, thereby avoiding the residue of sludge on the surface of the bottom plate and the inner wall of the pressing box, effectively reducing the time for users to clean the pressing box and improving work efficiency.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0019] like Figure 1-3The sludge dewatering and pressing equipment with anti-sticking function shown includes a support 1, a pressing box 2 fixedly connected to the support 1, and a first hydraulic rod 5 connected to the support 1. The output end of the first hydraulic rod 5 is connected to a pressure plate 6. The pressure plate 6 matches the inner cavity shape of the pressing box 2 and is set directly above the pressing box 2. Both the upper and lower ends of the pressing box 2 are set as open, and a bottom plate 3 matching the inner cavity shape is slidably connected to the inner wall of the pressing box 2. Multiple water filtering holes 4 are opened on the bottom plate 3. A second hydraulic rod 7 is connected to the support 1, and a top plate 8 is connected to the output end of the second hydraulic rod 7. The top plate 8 is set directly below the bottom plate 3. A feeding plate 12 is fixedly connected to the top of the outer end of the pressing box 2. The feeding plate 12 is set at an inclination. A third hydraulic rod 10 is installed on the support 1. A push plate 11 is set on the side of the top of the pressing box 2 away from the feeding plate 12. The push plate 11 is connected to the output end of the third hydraulic rod 10.

[0020] Sludge dewatering and pressing equipment is a type of equipment used to treat sludge. Its main function is to reduce the moisture content of sludge through physical methods, thereby reducing the volume and weight of the sludge and facilitating subsequent processing or disposal. Pressing equipment typically uses mechanical pressure to squeeze out the water from the sludge, making it drier. This equipment is widely used in wastewater treatment plants, sludge treatment plants, and other environments, helping to reduce waste treatment and disposal costs while minimizing environmental impact. However, with existing pressing devices, a large amount of sludge residue easily adheres to the inner wall of the container after pressing. Users need to spend a lot of time cleaning the inside of the container after each pressing, otherwise it will affect the subsequent pressing effect and seriously reduce work efficiency.

[0021] In this design, the user inputs sludge into the pressing chamber 2, where it accumulates on the surface of the bottom plate 3. The user then activates the first hydraulic rod 5 to move the pressure plate 6 downwards, allowing it to enter the inner cavity of the pressing chamber 2 and compress the accumulated sludge. Because the pressure plate 6 is in close contact with the inner wall of the pressing chamber 2, the water in the sludge is squeezed out and can only be discharged downwards through multiple filter holes 4 on the bottom plate 3. After the water is drained, the user activates the first hydraulic rod 5 again to reset the pressure plate 6. Then, the user activates the second hydraulic rod 7 to move the top plate 8 upwards, connecting the top plate 8 with the bottom plate 3. After contact, the base plate 3 will be pushed upward until the upper surface of the base plate 3 is flush with the top of the support 1. Since the outer end of the base plate 3 is in close contact with the inner wall of the pressing box 2, the sludge adhering to the inner wall of the pressing box 2 can be pushed upward, so that all the sludge inside the pressing box 2 is concentrated at the top of the base plate 3 and comes to the upper side of the pressing box 2. Then the user starts the third hydraulic rod 10 to drive the push plate 11 to move. The push plate 11 pushes all the sludge accumulated on the base plate 3 onto the discharge plate 12 to achieve the discharge of sludge. Then the third hydraulic rod 10 and the second hydraulic rod 7 are reset.

[0022] The top of the feeding plate 12 is flush with the top of the pressing box 2, the bottom of the push plate 11 abuts against the top of the pressing box 2, multiple water filtering holes 4 are arranged in a matrix, and multiple ejector pins 9 that cooperate with the water filtering holes 4 are fixedly connected on the top plate 8. After the bottom plate 3 slides upward to the limit distance, its upper surface is flush with the top of the pressing box 2.

[0023] In this solution, when the top plate 8 pushes the bottom plate 3, multiple pins 9 on the top plate 8 will be inserted into multiple filter holes 4 on the bottom plate 3. The length of the pins 9 is consistent with the depth of the filter holes 4. Through the insertion of the pins 9, the residual sludge in the filter holes 4 can be pushed out to the upper side of the bottom plate 3, thus avoiding the clogging of the filter holes 4.

[0024] Both sides of the top of the pressing box 2 are fixedly connected to baffles 13. The pair of baffles 13 are symmetrical to each other. The two ends of the push plate 11 abut against the pair of baffles 13 respectively. The baffles 13 extend from the top of the pressing box 2 to the feeding plate 12.

[0025] In this design, the baffle 13 can prevent sludge from falling from the side of the top of the support 1 and can help push all the sludge onto the discharge plate 12 for discharge.

[0026] The specific implementation process is as follows:

[0027] In use, the user puts sludge into the pressing chamber 2, where it accumulates on the surface of the bottom plate 3. The user then activates the first hydraulic rod 5, causing the pressure plate 6 to move downwards, entering the inner cavity of the pressing chamber 2 and squeezing the accumulated sludge. The water in the sludge is squeezed out and discharged downwards through multiple filter holes 4 on the bottom plate 3. After the water is drained, the user activates the first hydraulic rod 5 again, causing the pressure plate 6 to return to its original position. Then, the user activates the second hydraulic rod 7, causing the top plate 8 to move upwards. After the top plate 8 comes into contact with the bottom plate 3, multiple ejector pins 9 on the top plate 8 insert into the multiple filter holes 4 on the bottom plate 3. The top plate 8 can push the sludge remaining in the filter hole 4 to the upper side of the bottom plate 3. Then, the top plate 8 will push the bottom plate 3 upward until the upper surface of the bottom plate 3 is flush with the top of the support 1. During the process, the top plate 8 will push the sludge sticking to the inner wall of the pressing box 2 upward, so that all the sludge inside the pressing box 2 is concentrated at the top of the bottom plate 3 and comes to the upper side of the pressing box 2. Then, the user will activate the third hydraulic rod 10 to drive the push plate 11 to move. The push plate 11 will push all the sludge accumulated on the bottom plate 3 onto the discharge plate 12 to realize the discharge of sludge. Then, the user will control the third hydraulic rod 10 and the second hydraulic rod 7 to reset.
