Description

Technical Field

[0001] This utility model relates to the field of sludge pressing and dewatering technology, and in particular to a sludge pressing and dewatering device. Background Technology

[0002] Sludge with high water content often leaks and pollutes the environment. Therefore, pressing and dewatering is a crucial step in sludge treatment. Generally, pressing and dewatering devices are used to process sludge. By using mechanical pressure to squeeze out the water from the sludge, the volume of sludge can be reduced, saving storage space. The squeezed water can also be filtered and reused.

[0003] Existing equipment typically performs pressing and dewatering of sludge by directly squeezing and pressing it after the sludge is fed in. This one-time pressing and dewatering method results in incomplete pressing and low dewatering efficiency. Furthermore, all materials must be unloaded from the equipment after each pressing before the next material can be fed in, leading to low work efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A sludge pressing and dewatering device includes: two sets of pre-press dewatering machines and a deep press dewatering machine, wherein the two sets of pre-press dewatering machines are symmetrically arranged on both sides of the deep press dewatering machine;

[0006] Tracks are installed inside the pre-compression dewatering machine and the deep-compression dewatering machine;

[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0023] Existing equipment typically performs pressing and dewatering of sludge by directly squeezing and pressing it after the sludge is fed in. This one-time pressing and dewatering method results in incomplete pressing and low dewatering efficiency. Furthermore, all materials must be unloaded from the equipment after each pressing before the next material can be fed in, leading to low work efficiency.

[0024] To resolve this issue, please refer to [link / reference]. Figure 1-3 A sludge pressing and dewatering device includes: two sets of pre-press dewatering machines 1 and deep press dewatering machines 2, with the two sets of pre-press dewatering machines 1 symmetrically arranged on both sides of the deep press dewatering machine 2;

[0025] Track 3 is installed inside the pre-compression dewatering machine 1 and the deep-compression dewatering machine 2;

[0026] The filter press 4, which is installed inside the pre-press dewatering machine 1 via track 3, is used for pressing and dewatering.

[0027] Fixed platform 5 is installed on the side of the pre-compression dewatering machine 1;

[0028] A retractable push-pull rod 6 is installed on the side of the filter press tank 4, and the bottom of the push-pull rod 6 is fixedly connected to the upper surface of the fixed platform 5.

[0029] Both the pre-press dehydrator 1 and the deep press dehydrator 2 are fixedly connected to the bottom of a drain pipe 7.

[0030] In use, sludge is injected into the filter press tank 4. The filter press tank 4 is pre-installed with plate and frame filter plates and other components. The injected sludge enters between the plate and frame and the filter plates. The sludge in the filter press tank 4 is pre-treated by the pre-press dewatering machine 1 to complete the initial pressing. After the pre-treatment is completed, the push rod 6 pushes the filter press tank 4 along the track 3 to the deep press dewatering machine 2 for fine treatment. After the fine treatment is completed, the push rod 6 pulls the filter press tank 4 back. Another set of pre-press dewatering machines 1 can drag the pre-treated filter press tank 4 to the deep press dewatering machine 2 for fine treatment. The two sets of pre-press dewatering machines 1 and one set of deep press dewatering machines 2 can be used in turn to replace each other, which greatly saves working time and improves production efficiency. Moreover, the pressed filtrate can be discharged in time through the drain pipe 7 to avoid environmental pollution and odor generation.

[0031] In one implementation, please refer to Figure 1-2 The pre-compression dewatering machine 1 includes a base 11, a hydraulic press 12, a support 13 and a limiting rod 14. The support 13 is fixedly installed above the base 11, the hydraulic press 12 is installed inside the support 13, and the limiting rod 14 is installed inside the support 13 and fixedly connected to the hydraulic press 12.

[0032] During use, the hydraulic press 12 compresses the filter press tank 4. The hydraulic press 12 can provide 100t of pressure to pre-press the filter press tank 4, which has a pre-treatment effect. When the hydraulic press 12 is pressurizing, the limit rod 14 limits and positions the hydraulic press 12 to prevent the hydraulic press 12 from being affected by positional deviation during the pressurization process.

[0033] In one implementation, please refer to Figure 1-2 The deep-press dewatering machine 2 includes a base 21, a hydraulic press 22, a support 23, and a limiting rod 24. The support 23 is fixedly installed above the base 21. The hydraulic press 22 is installed inside the support 23. The limiting rod 24 is installed inside the support 23 and is fixedly connected to the hydraulic press 22.

[0034] During use, the hydraulic press 22 squeezes the filter press 4. The hydraulic press 22 can provide 800t of pressure to perform deep pressing on the filter press 4, achieving a fine processing effect. When the hydraulic press 22 is pressurizing, the limit rod 24 plays a role in limiting and positioning the hydraulic press 22, so as to prevent the deep pressing work from being affected by the position displacement of the hydraulic press 22 during the pressurization process.

[0035] In one implementation, please refer to Figure 1-3 The push-pull rod 6 is an electric telescopic rod, and the telescopic length of the push-pull rod 6 is greater than the width of the pre-compression dewatering machine 1.

[0036] In use, the push-pull rod 6 can push and pull the filter press 4 to drive the filter press 4 to move, so that the sludge in the filter press 4 can be double-pressed and dewatered. After the pressing and dewatering is completed, the push-pull rod 6 can also pull the filter press 4 out of the pre-press dewatering machine 1, so as to facilitate the replacement or maintenance of the filter press 4, and also to facilitate the cleaning of the inside of the filter press 4.

[0037] In one implementation, please refer to Figure 1-3 The upper surface of the fixed platform 5 is provided with a slide rail 51, and the two sides of the slide rail 51 are symmetrically provided with limit grooves 511. The slide rail 51 is provided with a slide plate 52, and the surface of the slide plate 52 is provided with a telescopic limit rod 521. The end of the telescopic limit rod 521 is inserted into the limit groove 511.

[0038] When in use, when the telescopic limit rod 521 retracts, the limit groove 511 can no longer limit the slide plate 52. At this time, the slide plate 52 can move inside the slide rail 51. When the slide plate 52 slides and the telescopic limit rod 521 is aligned with the second set of limit grooves 511, the telescopic limit rod 521 extends and inserts into the limit groove 511 to perform the limiting work.

[0039] In one implementation, please refer to Figure 1-3 The end of the push-pull rod 6 is rotatably connected to a rotating block 61, and the bottom of the other end of the push-pull rod 6 is fixedly connected to the upper surface of the slide plate 52 by bolts. The end of the rotating block 61 away from the push-pull rod 6 is fixedly connected to the side of the filter press 4.

[0040] In use, the push-pull rod 6 is connected to the side of the filter press tank 4 via the rotating block 61, allowing the push-pull rod 6 to swing freely without being fixed, which facilitates the disassembly of the filter press tank 4 and reduces the storage space after disassembly. The bottom of the push-pull rod 6 is fixed to the slide plate 52. When the telescopic limit rod 521 retracts, the limit groove 511 can no longer limit the slide plate 52. The push-pull rod 6 will move itself, thereby driving the slide plate 52 to move inside the slide rail 51. When the slide plate 52 slides and aligns the telescopic limit rod 521 with the second set of limit grooves 511, the telescopic limit rod 521 extends and inserts into the limit groove 511 to perform the limiting work. At this time, the retraction of the push-pull rod 6 will pull the filter press tank 4 out of the pre-press dewatering machine 1, which facilitates the replacement or maintenance of the filter press tank 4 and the cleaning of the inside of the filter press tank 4.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
