Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater sludge removal treatment device. Background Technology

[0002] Wastewater treatment refers to the process of removing pollutants from wastewater through physical, chemical, and biological methods to ensure that the water quality meets discharge standards or reuse requirements. It is a core link in protecting the water environment and preventing water pollution, and is widely used in domestic sewage, industrial wastewater, agricultural wastewater, and other fields. In the wastewater treatment process, it is usually necessary to filter the sludge in the wastewater through filter press equipment. Existing filter press equipment consists of multiple filter plates and a pressing mechanism. By activating the pressing mechanism, the pressing plate is pushed to squeeze the filter plate group, so that the sealing surfaces of adjacent filter plates are tightly fitted to form multiple independent, sealed filter chambers. Then, the sludge pump sends the wastewater containing sludge into the filter chamber, filters out the water, and forms a sludge cake between the filter plates. After the sludge cake is unloaded, the next round of filtration cycle can be prepared.

[0003] However, during the unloading of the mud cake, the mud cake between the filter plates is removed by operating a long shovel, which is a time-consuming and labor-intensive operation. Utility Model Content

[0008] Preferably, the bottom end of the strut frame is provided with an arc-shaped structure.

[0009] Preferably, the side plate is provided with a mud-cutting assembly located above the mud scraper. The mud-cutting assembly includes a mounting frame, which is horizontally fixed between the two side plates.

The scraper rod then descends along the opposite side of the filter plate to scrape off the mud cake on the surface of the filter plate. Furthermore, when cleaning different filter plates, the position of the scraper rod can be adaptively adjusted by moving the adjustment component.

[0013] This invention uses the elastic force of a spring to stably open the adjacent filter press plates with a support frame, so that the scraper rod can scrape the mud cake.

[0014] This invention utilizes the reciprocating extension and retraction motion of a telescopic cylinder to cause the cutting plate to repeatedly cut and break the scraped mud cake into smaller segments, so that the mud cake can fall between the filter plates, further improving the efficiency of mud cake scraping and cleaning.

Detailed Implementation

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4 This utility model provides a wastewater sludge dewatering treatment device, including a filter press body 1. Multiple filter plates 2 that can slide on the filter press body 1 are provided on the filter press body 1. A pressing mechanism 3 for pressing the filter plates 2 together is provided on the filter press body 1. Slide rails 4 are provided on both the front and rear sides of the filter press body 1. A plate spreading carriage 5 that can separate the filter plates 2 is provided on the slide rails 4. A movable adjustment component 6 that can adjust the position of a lifting cylinder 7 is provided on the top of the filter press body 1. A top plate 8 is fixedly connected to the output end of the lifting cylinder 7. Side plates 9 are fixedly installed on both the front and rear sides of the top plate 8. Symmetrical scraper rods 10 are fixedly connected to the bottom of the side plates 9. A spreading component 11 is provided on the side plates 9.

[0023] The pressing mechanism 3 can squeeze multiple filter plates 2 together to facilitate the sludge removal and filtration of muddy wastewater. After filtration, the pressing mechanism 3 releases the pressure on the filter plates 2, and the plate spreading cart 5 slides along the slide rail 4 to move the filter plates 2 one by one, so that adjacent filter plates 2 can be separated and opened to unload the mud cake between the filter plates 2. The filter press body 1 has a controller, and through the controller and the corresponding program, the relevant drive mechanisms in the equipment can be controlled with corresponding instructions. The above are all technical means of existing filter presses.

[0024] Specifically, after the filter press plate 2 is moved by the plate spreading vehicle 5, the lifting cylinder 7 extends, so that the sliding hole 111 stably opens the adjacent filter press plate 2, and the mud scraper 10 is lowered to the opposite side of the filter press plate 2 to scrape off the mud cake on the surface of the filter press plate 2. When cleaning different filter press plates 2, the position of the mud scraper 10 can be adaptively adjusted by the moving adjustment component 6.

[0025] Preferably, the movable adjustment component 6 includes a support frame 61, which is fixedly installed on the left and right sides of the filter press body 1. A movable frame 62 is fixedly installed on the top of the support frame 61. An adjusting screw 63 is rotatably connected to the middle of the movable frame 62. A motor 64 is fixedly installed on the movable frame 62. The output end of the motor 64 is fixedly connected to one end of the adjusting screw 63. Symmetrical slide rails 65 are provided on the front and rear sides of the movable frame 62. A sliding plate 66 is slidably installed on the slide rails 65. The middle of the sliding plate 66 is threadedly connected to the adjusting screw 63. A lifting cylinder 7 is fixedly installed on the sliding plate 66.

[0026] The adjustment screw 63 is driven to rotate by the motor 64, and the sliding plate 66 can be linearly slid along the slide rail 65 by the screw drive of the adjustment screw 63, thereby realizing the adjustment of the position of the scraper 10. The adjustment distance is controlled by the controller and program of the filter press body 1.

[0027] Preferably, the spreading assembly 11 includes a sliding hole 111 opened on the side plate 9, a spring 112 is provided in the sliding hole 111, and symmetrical support rods 113 are slidably installed on the side plate 9 through the sliding hole 111, and the two ends of the spring 112 are fixedly connected to the side plate 9 and the support rods 113 respectively.

[0028] Specifically, during the descent of the side plate 9, the bottom end of the support frame 113 first contacts the filter press plate 2, the spring 112 is compressed, and at the same time the support frame 113 squeezes the filter press plates 2 on both sides, stably opening the adjacent filter press plates 2 so that the scraper rod 10 can scrape the mud cake.

[0029] Preferably, the bottom end of the support frame 113 is provided with an arc-shaped structure to facilitate the compression between the support frame 113 and the filter press plate 2.

[0030] Furthermore, a mud-cutting assembly 12 is provided on the side plate 9 above the scraper rod 10. The mud-cutting assembly 12 includes a mounting frame 121, which is horizontally fixed between the two side plates 9. Symmetrical sliding grooves 122 are provided on the side plates 9. Symmetrical slides 123 are slidably installed between the two side plates 9 through the sliding grooves 122. A cutting plate 124 is fixedly connected to the bottom of the slides 123. A telescopic cylinder 125 is fixedly installed on the mounting frame 121. A connecting plate 126 is fixedly connected to the output end of the telescopic cylinder 125. Symmetrical transmission plates 127 are rotatably connected to the left and right sides of the connecting plate 126. The side of the two transmission plates 127 away from the connecting plate 126 is rotatably connected to the two slides 123 respectively.

[0031] Specifically, for sludge cakes with a certain moisture content after filtration, the integrity of the sludge cake is maintained during removal. After the sludge cake is removed, under the action of friction, there may be a situation where the sludge cake tilts and gets stuck between the filter plates 2. Therefore, during the process of scraping the sludge cake by the scraper rod 10, the reciprocating extension and retraction of the telescopic cylinder 125 causes the connecting plate 126 to drive the slide frame 123 to slide back and forth in the slide groove 122 through the transmission plate 127. The cutting plate 124 reciprocates to cut and break the scraped sludge cake into small segments so that the sludge cake can fall between the filter plates 2, further improving the efficiency of sludge cake scraping and cleaning.

[0032] Preferably, the slide 123 and the cutting plate 124 are hollowed out to facilitate the shredded mud cake falling between the filter plates 2.
