Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering, and particularly relates to a sludge hydraulic dewatering and drying mechanism. Background Art

[0002] Sludge hydraulic dewatering technology is an efficient sludge treatment method. By applying high pressure to squeeze out the water in the sludge, the moisture content of the sludge is significantly reduced. For some harmless sludge, after drying treatment, it can be processed into building materials to achieve the recycling of resources, which has environmental and social benefits.

[0003] At present, when the existing sludge hydraulic dewatering equipment is used to dehydrate and dry the sludge, there is a problem of blockage of the dewatering filter holes, resulting in poor dewatering and drying effects of the sludge. And if continuous pressure is applied when the filter holes are blocked, it is easy to cause equipment damage. In addition, after the dehydration is completed, it is not easy to carry out the operation of taking out the mud cake. Therefore, it is necessary to design a sludge hydraulic dewatering and drying mechanism. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a sludge hydraulic dewatering and drying mechanism, which solves the problems raised in the above background art.

[0010] Further, a first hydraulic telescopic rod and two second hydraulic telescopic rods are installed on the machine body. The output end of the first hydraulic telescopic rod is fixedly connected to the pressing plate, and the output ends of the two second hydraulic telescopic rods are fixedly connected to the moving ring.

[0012] Further, the length of the first spiral groove is less than or equal to the difference between the height of the dewatering cylinder and the diameter of the feed pipe. Positioning rings are fixedly installed on both the upper and lower side walls of the connecting gear ring. Annular grooves that rotatably cooperate with the two positioning rings are opened on the side wall of the installation groove.

[0013] Further, a through groove that cooperates with the support plate is opened on the side wall of the machine body. A sewage discharge groove is opened on the side wall of the machine body, and a rotating shaft is rotatably installed in the sewage discharge groove. A sealing door that cooperates with the sewage discharge groove is fixedly installed on the rotating shaft.

[0014] Further, the deflection assembly is composed of a rotating sleeve, a fixed gear, a connecting gear, and a moving rod.

[0033] Referring to Figures 1-11 , a sludge hydraulic dehydration and drying mechanism, includes a machine body 1, a feed pipe 2 is fixedly communicated with the side wall of the machine body 1, a drainage port 3 is opened at the bottom of the machine body 1, and also includes a dehydration cylinder 5 fixedly installed in the machine body 1, and a bottom plate 6 is installed at the bottom of the dehydration cylinder 5. A pressing plate 9 and a moving ring 11 are slidably installed in the machine body 1. The pressing plate 9 is hermetically slidably installed inside the dehydration cylinder 5, and the moving ring 11 is hermetically slidably installed outside the dehydration cylinder 5, and the height difference between the pressing plate 9 and the moving ring 11 is greater than the diameter of the feed pipe 2. Before the dehydration treatment, sludge is input into the dehydration cylinder 5 in the machine body 1 through the feed pipe 2. At this time, the pressing plate 9 is located above the feed pipe 2, and the moving ring 11 is located below the feed pipe 2. Therefore, the sludge can smoothly enter the dehydration cylinder 5 and is located below the pressing plate 9. When a certain amount of sludge is input, the input is stopped, so that the pressing plate 9 moves down, and the water in the sludge can be discharged by the pressure action. The presence of the bottom plate 6 can ensure that the sludge in the dehydration cylinder 5 will not leak from the bottom during the dehydration process, ensuring that the sludge can be effectively squeezed and dehydrated.

[0034] The method for conveying sludge from the feed pipe 2 can adopt an existing pump body, and its working principle and specific structure will not be elaborated here. When discharging the discharged water, a pipeline for guiding the water body can be connected to the bottom of the drainage port 3 to discharge the water discharged from the sludge to a designated position. A plurality of filter holes are opened on the side wall of the dehydration cylinder 5 and the bottom of the bottom plate 6.

[0035] A hydraulic telescopic rod I (8) and two hydraulic telescopic rods II (10) are installed on the machine body (1). The output end of the hydraulic telescopic rod I (8) is fixedly connected to a pressing plate (9), and the output ends of the two hydraulic telescopic rods II (10) are fixedly connected to a moving ring (11). A hydraulic system (7) that cooperates with the hydraulic telescopic rod I (8) and the hydraulic telescopic rods II (10) is installed on the machine body (1). The hydraulic system (7) is an existing device used to control and adjust the telescoping of the hydraulic telescopic rod I (8) and the hydraulic telescopic rods II (10). Its working principle and specific structure will not be elaborated here. When the hydraulic system (7) operates, the up-and-down movement amplitude and speed of the pressing plate (9) and the moving ring (11) within the machine body (1) can be controlled through the hydraulic telescopic rod I (8) and the hydraulic telescopic rods II (10), facilitating better hydraulic dehydration treatment of the sludge.

[0036] Rotate the rotating ring (13). An annular groove (12) is formed on the inner wall of the moving ring (11). The rotating ring (13) is rotatably installed in the annular groove (12), and a plurality of anti-blocking bristles (14) are fixedly installed on the inner wall of the rotating ring (13). During the downward movement of the moving ring (11) along the side wall of the dehydration cylinder (5), the moisture adhering to the side wall of the dehydration cylinder (5) can be scraped off, reducing subsequent moisture residue. At the same time, during the downward movement of the moving ring (11), the rotating ring (13) rotates simultaneously, enabling the anti-blocking bristles (14) thereon to clean a plurality of filter holes on the side wall of the dehydration cylinder (5), avoiding the possibility of the filter holes being blocked, greatly improving the dehydration and drying effect of the sludge, and reducing the possibility of equipment damage.

[0037] To improve the cleaning effect on the filter holes of the dehydration cylinder (5) and the removal effect of the sludge, the anti-blocking bristles (14) are arranged to incline downward from the end far away from the dehydration cylinder (5) to the end close to the dehydration cylinder (5), so that during the cleaning process, part of the sludge can be thrown away towards the lower end of the rotating ring (13) by using the inclination angle, thus facilitating better maintaining the cleanliness of the outer wall of the dehydration cylinder (5).

[0038] A driving component that cooperates with the rotating ring (13) is installed between the machine body (1) and the moving ring (11). The driving component is used to drive the rotating ring (13) to rotate when the moving ring (11) moves up and down along the dehydration cylinder (5), so that the anti-blocking bristles (14) can perform anti-blocking cleaning on the dehydration cylinder (5). The driving component is composed of a fixed gear ring (15), an installation groove (16), a connecting gear ring (17), a fixed rod (18), a convex block (19), and a first spiral groove (20);

[0039] The fixed gear ring 15 is fixedly installed on the side wall of the rotating ring 13. The installation groove 16 is opened on the side wall of the annular groove 12. The connecting gear ring 17 is rotatably installed in the installation groove 16. The fixed rod 18 is fixedly installed in the machine body 1 and is slidably connected with the moving ring 11. The convex block 19 is fixedly installed on the inner wall of the connecting gear ring 17. The first spiral groove 20 is opened in the middle section of the fixed rod 18 and is matched with the convex block 19. During the up and down movement of the moving ring 11, the connecting gear ring 17 is driven to move simultaneously. Since the position of the fixed rod 18 remains unchanged, during the movement of the connecting gear ring 17, the convex block 19 thereon will rotate along the first spiral groove 20, so that the connecting gear ring 17 rotates. Furthermore, under the meshing effect of the connecting gear ring 17 and the fixed gear ring 15, the rotating ring 13 rotates while moving up and down along the moving ring 11, realizing the anti-blocking and cleaning treatment of the filter holes on the dewatering cylinder 5;

[0040] The length of the first spiral groove 20 is less than or equal to the difference between the height of the dewatering cylinder 5 and the diameter of the feed pipe 2. The advantage of this dimension design is that it can ensure that when the moving ring 11 moves up and down along the dewatering cylinder 5 and is not separated from the dewatering cylinder 5, the rotating ring 13 can perform a rotating action, ensuring the cleaning effect of the anti-blocking bristles 14 on the dewatering cylinder 5. Positioning rings are fixedly installed on the upper and lower side walls of the connecting gear ring 17, and annular grooves for rotatably cooperating with the two positioning rings are opened on the side wall of the installation groove 16.

[0041] Support plate 22. A rotating rod 21 is rotatably installed in the machine body 1. The support plate 22 is fixedly installed at the top of the rotating rod 21 and supports the bottom of the bottom plate 6. A deflection assembly matched with the rotating rod 21 is installed in the machine body 1. The deflection assembly is used to drive the support plate 22 to deflect and separate from the bottom plate 6 when the moving ring 11 moves to the bottom plate 6. The deflection assembly is composed of a rotating sleeve 23, a fixed gear 24, a connecting gear 25 and a moving rod 26;

[0042] The rotating sleeve 23 is sealed and rotatably installed on the bottom wall of the machine body 1. The fixed gear 24 is fixedly installed on the rotating sleeve 23. The connecting gear 25 is fixedly installed at the bottom of the rotating rod 21, and the connecting gear 25 meshes with the fixed gear 24. The moving rod 26 is slidably installed in the rotating sleeve 23, and a second spiral groove is formed in the middle section of the moving rod 26. A guiding block matching with the second spiral groove is fixedly installed on the inner wall of the rotating sleeve 23. When the moving ring 11 does not move to the bottom plate 6, it does not contact the moving rod 26. At this time, both the rotating rod 21 and the rotating sleeve 23 are in a static state. The support plate 22 is located at the bottom of the bottom plate 6 to support the bottom plate 6, ensuring the support effect of the bottom plate 6 on the bottom of the dehydration cylinder 5 during the hydraulic dehydration process, and ensuring that the sludge can be effectively dehydrated and dried. When the moving ring 11 moves to the bottom and contacts the upper surface of the bottom plate 6, the bottom of the moving ring 11 just contacts the top of the moving rod 26. At this time, when the moving ring 11 continues to move downward, it will drive the moving rod 26 to move downward. Then, under the cooperation of the guiding block and the second spiral groove, the rotating sleeve 23 rotates. Using the meshing effect of the fixed gear 24 and the connecting gear 25, the rotating rod 21 rotates simultaneously, causing the support plate 22 to deflect and separate from the bottom plate 6. After the support plate 22 separates from the bottom plate 6, the moving ring 11 is exactly aligned with the height of the bottom plate 6. At this time, when the moving ring 11 continues to move downward, it drives the bottom plate 6 to move downward, separating it from the dehydration cylinder 5. To improve the connection effect between the moving ring 11 and the bottom plate 6, a rubber ring can be provided on the inner wall of the moving ring 11.

[0043] A positioning disk 28 is fixedly installed at the bottom of the moving rod 26, and a spring 27 is installed between the positioning disk 28 and the bottom wall of the machine body 1. With the cooperation of the positioning disk 28 and the spring 27, when the moving ring 11 moves upward and separates from the moving rod 26, the rotating sleeve 23 can be rotated back to its original position, so that the support plate 22 can effectively support the bottom of the bottom plate 6 again. To ensure that the moving rod 26 can move up and down stably to drive the rotating sleeve 23 to rotate, a sliding hole is formed in the positioning disk 28, and a sliding rod vertically arranged at the bottom of the machine body 1 and slidably matched with the sliding hole is provided. The sliding hole and the sliding rod are not shown in the figure.

[0044] A through groove matching with the support plate 22 is formed on the side wall of the machine body 1. A sewage discharge groove is formed on the side wall of the machine body 1, and a rotating shaft 29 is rotatably installed in the sewage discharge groove. A sealing door 4 matching with the sewage discharge groove is fixedly installed on the rotating shaft 29. A chain drive structure 30 is installed between the rotating rod 21 and the rotating shaft 29. With the design of the chain drive structure 30, when the moving ring 11 moves downward to drive the support plate 22 to separate from the bottom plate 6, the rotating shaft 29 can be rotated to drive the sealing door 4 to open at the same time. Then, the staff can take out the mud cake on the bottom plate 6 through the sewage discharge groove, effectively reducing the difficulty of taking out the mud cake. The chain drive structure 30 is a common technical means using a sprocket and a chain in the prior art, and its working principle and specific structure will not be elaborated here.

[0045] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
