If it is not handled properly, it will cause serious secondary pollution, which has become an environmental problem faced by all towns. The core issue of sludge treatment is dehydration. Only when the water content of sludge is reduced to a certain level can the subsequent final disposal, such as incineration, pyrolysis, composting, landfill, etc., be carried out.

[0003] The existing presses for sludge dewatering occupy a large area, consume high energy, have low processing efficiency, and cannot meet the needs of large-scale production and processing. Therefore, it is particularly important to design a press for sludge dewatering to solve the above technical problems. Utility Model Content

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] The utility model provides a sludge dewatering press, comprising a frame 1, a mud pressing mold 2 is slidably connected in the frame 1, a rear pressing head 3 is detachably connected to the inner wall of the left end of the frame 1, a feed inlet 201 is arranged on the top of the mud pressing mold 2, a discharge port 6 is arranged on the bottom of the frame, a front pressing head 4 is slidably arranged on the right end of the mud pressing mold 2, an oil cylinder 5 is fixedly connected to the frame 1, a sliding rod 501 is slidably connected in the oil cylinder 5, the sliding rod 501 and the front pressing head 4 are fixedly connected, the two ends of the mud pressing mold 2 are through openings, and the mud pressing mold 2 is provided with a feed inlet 201. The opening sizes on both sides of the mold 2 are consistent with the diameter sizes of the front pressure head 4 and the rear pressure head 3. The front pressure head 4 and the rear pressure head 3 are evenly distributed with water outlet holes 9. The bottom of the frame is symmetrically distributed with slide rails 7. The bottom of the mud pressing mold 2 is fixedly connected with a pulley 701, and the pulley 701 can be slidably connected in the slide rail 7. Cylinders 8 are fixedly connected on both sides of the frame 1, and a piston rod 801 is slidably connected in the cylinder 8. Connecting plates 802 are fixedly connected on both sides of the mud pressing mold 2, and the connecting plates 802 are fixedly connected to the piston rod 801.

[0019] like Figure 1-3 As shown, when the sludge dewatering press is actually used, in the initial stage of the sludge pressing work, the mud pressing mold 2 is in a stationary state and the rear pressure head 3 is located in the mud pressing mold 2 to block the opening on the left side of the mud pressing mold 2. At this time, the front pressure head 4 and the rear pressure head 3 on the right side both block the openings on both sides of the mud pressing mold 2, so that the mud pressing mold 2 forms a container that can carry sludge; the sludge to be squeezed is transported to the mud pressing mold 2 by an external sludge conveying mechanism, and after the sludge mold is filled with mud, the mold is driven by the cylinders 8 on both sides and the piston rod 801 drives the connecting plate 802 to cooperate, and the mud pressing mold 2 moves to the left as a whole, and the rear pressure head 3 moves to the right relative to the mud pressing mold 2, until the rear pressure head 3 slides relatively through the feed inlet 201 and forms a relatively closed squeezing environment with the front pressure head 4, the right side The oil cylinder 5 drives the front pressure head 4 to move to the left through the sliding rod 501 to start mud pressing. The water formed in the pressing process is discharged through the water outlet 9. After the mud pressing is completed, the main oil cylinder 5 returns to the initial position, and the mud pressing mold 2 continues to move to the left until the mud cake exits from the opening position at the right end of the mud pressing mold 2 and then falls from the discharge port 6. In this way, the mud pressing work is completed and the large-scale pressing work is carried out repeatedly. By setting a mud pressing mold 2 structure that can slide left and right in the frame 1, the amount of mud to be pressed can be flexibly controlled, and the sludge can be unloaded from the mud pressing mold 2 after the pressing is completed. The entire pressing process is semi-automated and processed, which meets the needs of modern production and processing. Compared with the conventional complex pressing structure, the pressing structure adopted by the utility model is compact as a whole, and the space layout is reasonable, which is easy for the staff to install and maintain.

[0020] Working principle: At the initial stage of sludge pressing, the sludge pressing mold is stationary and the rear pressure head is located in the sludge pressing mold to block the opening on the left side of the sludge pressing mold. At this time, the front pressure head and the rear pressure head on the right side both block the openings on both sides of the sludge pressing mold, so that the sludge pressing mold forms a container that can carry sludge; the sludge to be squeezed is transported to the sludge pressing mold by the external sludge conveying mechanism. After the sludge mold is filled with sludge, the mold is driven by the cylinders on both sides and the piston rod drives the connecting plate to cooperate with the sludge pressing mold as a whole. The rear pressure head moves to the left and moves to the right relative to the mud pressing mold until the rear pressure head slides relatively through the feed port and the front pressure head to form a relatively closed pressing environment. The right oil cylinder drives the front pressure head to the left through the sliding rod to start mud pressing. The water formed in the pressing process is discharged through the water outlet. After the mud pressing is completed, the main oil cylinder returns to the initial position, and the mud pressing mold continues to move to the left until the mud cake withdraws from the opening position at the right end of the mud pressing mold and then falls from the discharge port. In this way, a mud pressing work is completed, and large-scale pressing work is carried out in a reciprocating cycle.
