[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of an extrusion structure for a sludge treatment production line, including a base plate 13. The base plate 13 provides a stable installation foundation for the entire extrusion structure and bears the weight of all components above it. Side plates 1 are fixedly connected to the side walls of the base plate 13, reinforcing the structure from both sides and providing support for the sliding of components such as the moving plate 7. The moving plate 7 is slidably connected to the inner right wall of the side plate 1, and can slide horizontally along the inner wall of the side plate 1, thereby driving the filter cartridge 4 to move synchronously. The moving plate 7 is used to close the through-hole opening of the base plate 13. A water guide strip is provided on the upper side of the moving plate 7. A connecting block 8 is fixedly connected to the upper side of the moving plate 7, which connects the moving plate 7 and the filter cartridge 4. The filter cartridge 4 is fixedly connected to the left side of the connecting block 8. The filter cartridge 4 is the core container for containing sludge and performing extrusion dewatering. Its cylinder wall allows water to seep out. The filter cartridge 4 is the middle The filter cartridge 4 is equipped with a sliding pressure plate 2, which can slide up and down inside the filter cartridge 4 to directly apply pressure to the internal sludge. A hydraulic rod 3 is fixedly connected to the upper side of the pressure plate 2, which provides a strong driving force to control the lifting and lowering of the pressure plate 2 to achieve the squeezing action. A feeding cylinder 9 is fixedly connected to the lower side of the bottom plate 13. The feeding cylinder 9 is used to collect and discharge the sludge after squeezing and dewatering for convenient subsequent processing. An auxiliary component is provided on the outer wall of the filter cartridge 4 to assist the movement of the filter cartridge 4. An electric telescopic rod 10 is fixedly connected to the right side of the side plate 1. The electric telescopic rod 10 can extend and retract to push the moving plate 7, thereby controlling the horizontal position of the filter cartridge 4. A water filtration component is provided on the inner wall of the bottom plate 13 for water filtration. A limit frame 5 is fixedly connected to the inner wall of the side plate 1 to limit the movement range of the filter cartridge 4 and prevent the filter cartridge 4 from deviating from the working position.

[0032] Reference Figures 2-4The water filtration assembly includes a filter plate 11, which is the main filtration component. The filter plate 11 intercepts solid particles in the sludge while allowing water to pass through. The filter plate 11 is snapped onto the inner wall of the base plate 13. A locking block 15 is elastically connected to the lower inner wall of the filter plate 11 via a spring 16. The spring 16 provides elastic force to the locking block 15, ensuring that the locking block 15 always tends to clamp the filter plate 11. The outer wall of the locking block 15 is slidably connected to the lower inner wall of the base plate 13. The upper side of the locking block 15 is inclined. This inclined design allows the filter plate 11 to automatically compress and retract the locking block 15 during installation. The snapping action secures the filter plate 11 to the base plate 13, preventing the filter plate 11 from... During operation, the right side of the locking block 15 is engaged with the inner wall of the filter plate 11. One end of the spring 16 is fixedly connected to the bottom inner wall of the base plate 13, and the other end of the spring 16 is fixedly connected to the left side of the locking block 15. A baffle 14 is fixedly connected to the left side of the locking block 15. The baffle 14 provides a certain degree of waterproofing and protection for the spring 16. A positioning block 17 is fixedly connected to the upper inner wall of the base plate 13. The positioning block 17 can quickly determine the installation position of the filter plate 11 and ensure that the filter plate 11 is accurately engaged with the base plate 13. There are two symmetrical positioning blocks 17, and the upper side of the positioning block 17 is flush with the upper side of the base plate 13.

[0033] Reference Figure 2 The auxiliary components include pulleys 12, which can convert the sliding friction between the filter cartridge 4 and the side plate 1 into rolling friction, greatly reducing the moving resistance. There are two sets of pulleys 12, with two symmetrical pulleys 12 in each set. The pulleys 12 are slidably connected to the inner wall of the groove 6 and fixedly connected to the outer wall of the filter cartridge 4. The inner wall of the side plate 1 is provided with a groove 6, which provides a precise sliding trajectory for the pulleys 12 and restricts the direction of movement of the pulleys 12.

[0034] Working principle: First, the sludge to be treated is placed into the filter cylinder 4. At this time, the electric telescopic rod 10 is in the retracted state, driving the moving plate 7 and the filter cylinder 4 to the initial working position, and the filter cylinder 4 is limited and fixed by the limiting frame 5. Then, the hydraulic rod 3 starts and extends downward, pushing the pressure plate 2 to slide downward in the filter cylinder 4. The pressure plate 2 applies pressure to the sludge in the filter cylinder 4. Under the pressure, the sludge gradually dewaters, and the seeping water flows out through the cylinder wall of the filter cylinder 4. The wastewater flowing out onto the moving plate 7 is guided to the filter plate 11 in the water filtration assembly through the water guide strip. The water passes through the filter plate 11 to achieve dewatering, while the sludge is intercepted above the filter plate 11. After the dewatering is completed, the hydraulic rod 3 drives the pressure plate 2 to move upward out of the filter cylinder 4. Then, the electric telescopic rod 10 extends, pushing the moving plate 7 to slide horizontally to the right along the inner wall of the side plate 1. The moving plate 7 drives the filter cylinder 4 through the connecting block 8. The filter cylinder 4 moves synchronously, and the pulley 12 on the outer wall of the filter cylinder 4 slides in the groove 6 of the side plate 1, which helps the filter cylinder 4 to move smoothly. At this time, the moving plate 7 no longer closes the through hole opening of the bottom plate 13. After the filter cylinder 4 moves above the feeding cylinder 9, the sludge that has been dewatered in the filter cylinder 4 falls into the feeding cylinder 9 through the through hole opening of the bottom plate 13 under its own gravity and subsequent possible auxiliary pushing action, and is discharged through the feeding cylinder 9, completing one sludge compression treatment process. During the operation of the water filtration assembly, the filter plate 11 is fixed to the bottom plate 13 by the locking block 15. The spring 16 provides a continuous elastic force for the locking block 15 to ensure the stable operation of the filter plate 11. When it is necessary to clean or replace the filter plate 11, pull the baffle 14 to move the locking block 15 to the left and compress the spring 16, so that the locking block 15 is disengaged from the filter plate 11, and the filter plate 11 can be taken out from the bottom plate 13.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
