Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to a sludge treatment device and a sludge treatment method. Background Technology

[0002] During sludge filtration, the equipment shafts often come into direct contact with the sludge. Because the sludge contains a large number of solid particles, colloids, and other impurities, these impurities easily adhere to the shafts and the internal surfaces of the equipment, forming stubborn dirt. As the equipment is used over time, this dirt gradually accumulates and thickens, increasing the rotational resistance of the shafts and affecting the normal operation of the equipment. Moreover, this dirt has strong adhesion, making it difficult to completely remove using traditional cleaning methods. For example, some equipment relies solely on simple rinsing methods, which cannot reach the tiny crevices of the shafts and the internal surfaces of the equipment, resulting in severe dirt residue and poor cleaning effectiveness. The dirt remaining on the shafts not only increases rotational resistance but also has various adverse effects on the performance of the equipment.

[0003] Existing sludge treatment equipment typically requires significant time and manpower to clean residual sludge. Some equipment necessitates disassembling parts of the structure for internal cleaning, which is not only cumbersome but also requires specialized technicians, increasing the difficulty and cost of cleaning. Furthermore, the complexity and lengthy cleaning process lead to prolonged equipment downtime, impacting production efficiency. Therefore, a wastewater sludge separation and treatment device is proposed to address these issues. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a sludge treatment device and a sludge treatment method, which has the advantage of facilitating the cleaning of residual dirt in the device after sludge filtration.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A sludge treatment device includes two side frames, with a filter cylinder installed between the two side frames. A frame plate is fixedly connected to the left side frame, and a rotating shaft is rotatably connected to the frame plate. A cross is fixedly connected to the rotating shaft, and multiple scrapers that fit against the inner wall of the filter cylinder are fixedly connected around the cross. Scraper discs and baffles are slidably connected to both sides of the filter cylinder, and the scraper discs are slidably connected to the multiple scrapers. A feed inlet is opened on the baffle, and a cover plate is detachably connected to the feed inlet.

[0007] The rotating shaft is fitted with a bushing, and the scraper and the circular plate are respectively fixed to the left and right sides of the bushing.

[0008] A circular plate larger than the diameter of the filter cartridge is fixed to the outer side of the baffle. A motor III is fixed to the left side frame. The output shaft of motor III is connected to a threaded sleeve through a coupling. A screw is threaded inside the threaded sleeve. A U-shaped plate inserted into the edge of the circular plate is fixed to the screw. Attached Figure Description

Detailed Implementation

[0022] See Figures 1 to 8 A schematic diagram of an embodiment of the present invention is shown, which facilitates the cleaning of residual dirt on the equipment after sludge filtration.

[0023] A sludge treatment device includes two side frames 102, with a filter cylinder 103 installed between the two side frames 102. A frame plate 201 is fixedly connected to the left side frame 102, and a rotating shaft 204 is rotatably connected to the frame plate 201. A cross 206 is fixedly connected to the rotating shaft 204, and multiple scrapers 207 that are attached to the inner wall of the filter cylinder 103 are fixedly connected around the cross 206. A scraper 302 and a baffle 303 are slidably connected to both sides of the filter cylinder 103, and the scraper 302 is slidably connected to the multiple scrapers 207. Multiple filter holes evenly distributed in the filter cylinder 103 are located between the scraper 302 and the baffle 303. A feed inlet is opened on the baffle 303, and a cover plate 305 is detachably connected to the feed inlet.

[0024] Both of the aforementioned frame plates 201 are fixedly connected to the base 101, and a box I 107 is placed on the base 101 below the filter holes on the filter cartridge 103.

[0025] Box II 108 is placed on the base 101 below and to the right of the filter cartridge 103.

[0026] After opening the cover plate 305, the sludge is fed into the filter cylinder 103 through the feed inlet. The sludge in the filter cylinder 103 is located between the scraper 302 and the baffle 303. The cover plate 305 is closed over the feed inlet, and the rotating shaft 204 is controlled to rotate. The rotating shaft 204 drives multiple scrapers 207 to rotate through the cross 206 to turn the sludge, so that the sludge is filtered out from the filter holes on the filter cylinder 103 and collected in the box I 107. The garbage and gravel mixed in the sludge are filtered out by the filter holes on the filter cylinder 103 and remain in the filter cylinder 103. When it is necessary to clean the impurities in the filter cylinder 103, the baffle 303 is opened to the right. As the baffle 303 moves to the right, it can drive the scraper 302 to slide to the right in the bushing 301. As the scraper 302 slides to the right, it pushes the garbage and gravel in the filter cylinder 103 to the right. The impurities fall from the right side of the filter cylinder 103 and are collected in the box II 108.

[0027] Secondly, since the sludge may contain a large amount of colloids and other impurities, these colloids are easy to adhere to the inner wall of the filter cylinder 103 and the surface of the multiple scrapers 207, forming stubborn dirt. As the equipment is used for a longer period of time, the dirt will gradually accumulate and thicken, resulting in increased rotational resistance of the shaft 204, affecting the normal operation of the equipment. Moreover, the dirt has strong adhesion, and traditional cleaning methods are not convenient to penetrate into the filter cylinder 103 to clean its inner wall and the gaps between the multiple scrapers 207 and their contact. Therefore, in this application, the scraper 302 slides to the right inside the side frame 102 while scraping away the impurities on the inner wall of the filter cylinder 103 and the multiple scrapers 207. This achieves the cleaning of impurities inside the filter cylinder 103 while cleaning the dirt remaining on the multiple scrapers 207 and the dirt remaining on the inner wall of the filter cylinder 103, reducing the difficulty and cost of cleaning.

[0028] See Figure 7 and 8 A schematic diagram of an embodiment of the self-discharging of waste and impurities according to the present invention is shown;

[0029] A bushing 301 is fitted onto the rotating shaft 204, and the scraper 302 and the circular plate 304 are respectively fixed to the left and right sides of the bushing 301.

[0030] When the baffle 303 moves to the right and opens, it will drive the scraper 302 to move to the right synchronously through the bushing 301, thereby cleaning the garbage in the filter cartridge 103 and automatically opening the right side of the filter cartridge 103 so that the garbage and impurities can be discharged by themselves.

[0031] See Figures 7 to 9 A schematic diagram of an embodiment of the invention that facilitates cleaning of the scraper 302 and the baffle 303 is shown.

[0032] A circular plate 304 larger than the diameter of the filter cartridge 103 is fixedly connected to the outer side of the baffle 303. The cover plate 305 is detachably connected to the circular plate 304 by screws. A motor III 306 is fixedly connected to the left side frame 102. The output shaft of the motor III 306 is connected to a threaded sleeve 307 through a coupling. A screw 308 is threadedly connected inside the threaded sleeve 307. A U-shaped plate 309 inserted into the edge of the circular plate 304 is fixedly connected to the screw 308.

[0033] Motor III 306 starts and drives threaded sleeve 307 to rotate. Threaded sleeve 307 drives screw 308 to move to the right through the thread. Screw 308 drives U-shaped plate 309 and circular plate 304 to move to the right. Circular plate 304 drives baffle 303 to move to the right, opening the right side of filter cartridge 103. Then, baffle 303 drives scraper 302 to move to the right through bushing 301 to clean the inner wall of filter cartridge 103 and multiple scrapers 207.

[0034] Because the threads between the threaded sleeve 307 and the screw 308 have a self-locking property, the scraper 302 and the baffle 303 can be locked after moving to the right and stopping. This makes it easy to clean the dirt remaining on the bushing 301 and the inner wall of the baffle 303 that have moved to the outside of the filter cartridge 103, and also makes it easy to clean the dirt on the surface of the scraper 302 that can be exposed on the right side of the filter cartridge 103.

[0035] Furthermore, the bushing 301 can block the rotating shaft 204 located inside the filter cartridge 103, so that dirt will not remain on the rotating shaft 204 and keep the rotating shaft 204 clean. At the same time, the bushing 301 moves to the right and extends to the outside of the filter cartridge 103, which also makes it easier to clean the bushing 301.

[0036] See Figure 10 and 11 This diagram illustrates an embodiment of scraping and cleaning dirt or sludge from the outer surface of the filter cartridge 103 according to the present invention.

[0037] The filter cartridge 103 is rotatably connected between two side frames 102, and a scraper 401 attached to the outer wall of the filter cartridge 103 is fixed between the two side frames 102.

[0038] The intermittently rotating filter cartridge 103 and the stationary scraper 401 create relative motion, allowing the scraper 401 to remove dirt or sludge from the outer surface of the filter cartridge 103, preventing the dirt or sludge from clogging the filter pores. The intermittent rotation of the filter cartridge 103 ensures that the scraper 401 contacts the entire outer surface of the filter cartridge 103, thereby cleaning the entire surface of the filter cartridge 103.

[0039] See Figure 11 The diagram shows an embodiment of unclogging filter holes according to the present invention;

[0040] Two electric push rods 402 are symmetrically fixed to the scraper 401. The telescopic ends of the two electric push rods 402 are fixed to the crossbeam 403. Multiple rods 404 inserted into the scraper 401 are fixed to the crossbeam 403. The multiple rods 404 can be inserted into the filter hole at the uppermost position.

[0041] The filter cartridge 103 rotates intermittently, so that after each rotation at a certain angle, a row of filter holes corresponds to multiple columns 404. When the electric push rods 402 on both sides are activated, they drive the crossbeam 403 to move downward. The crossbeam 403 can drive the multiple columns 404 to insert downward into the filter holes, thereby clearing the blocked filter holes and avoiding affecting the discharge of sludge.

[0042] Secondly, the scraper 401 is located above the filter cylinder 103, which does not affect the discharge of sludge from the inside of the filter cylinder 103 through the filter holes downwards, while allowing the impurities scraped off from the surface of the filter cylinder 103 to fall downwards along the surface of the filter cylinder 103 and be collected in the box I 107.

[0043] Furthermore, clearing the filter holes from above the filter cylinder 103 will not affect the internal agitation of the sludge. Under the influence of gravity, the sludge is located at the bottom inside the filter cylinder 103 and is discharged from the filter holes below. At the same time, multiple rods 404 clear the filter holes from above the filter cylinder 103.

[0044] Furthermore, the downward movement of the column rod 404 continues until its bottom surface is coplanar with the inner wall of the filter cylinder 103. Therefore, the bottom surface of the column rod 404 is an arc-shaped structure with the same curvature as the inner wall of the filter cylinder 103. When the column rod 404 moves downward to clear the filter holes, it pushes the impurities in the filter holes toward the inside of the filter cylinder 103. The continuously rotating scraper 207 scrapes away the impurities pushed out of the filter holes, thereby preventing the impurities from sticking to the lower end of the column rod 404 and re-entering the filter holes as the column rod 404 returns to its upward position, thus avoiding ineffective cleaning of the filter holes.

[0045] See Figure 4 and 5 A schematic diagram according to an embodiment of the present invention is shown;

[0046] A gear ring 104 is fixedly connected to the filter cartridge 103, and a motor I 105 is fixedly connected to the left side frame 102. The output shaft of the motor I 105 is fixedly connected to a gear I 106 that meshes and drives with the gear ring 104.

[0047] The motor I105 starts and drives the gear I106 to rotate. The gear I106 meshes with the gear ring 104 and drives the filter cartridge 103 to rotate intermittently. The scraper 401 cleans the sludge on the surface of the filter cartridge 103, and the vertically moving column 404 cleans the filter holes on the filter cartridge 103.

[0048] A motor II 202 is fixedly connected to the frame plate 201, a gear II 203 is fixedly connected to the output shaft of the motor II 202, and a gear III 205 that meshes and drives with the gear II 203 is fixedly connected to the rotating shaft 204.

[0049] Motor II 202 starts and drives gear II 203 to rotate. Gear II 203 meshes with gear III 205 and drives shaft 204 to rotate. Shaft 204 drives multiple scrapers 207, scraper 302, bushing 301, baffle 303 and circular plate 304 to rotate synchronously. Since the circular plate 304 and U-shaped plate 309 are connected by an insertion, there is no interference between the rotating circular plate 304 and the U-shaped plate 309 that can drive the circular plate 304 to move left and right.

[0050] A method for treating sludge using a sludge treatment device includes the following steps:

[0051] A: The sludge is fed into the filter cylinder 103 through the feed inlet, and the rotating shaft 204 is controlled to drive multiple scrapers 207 to rotate and turn the sludge.

[0052] B: The sludge is filtered out from the filter holes on the filter cylinder 103 and collected in the box I 107. The garbage and gravel in the sludge are filtered out and remain in the filter cylinder 103.

[0053] C: The rotation of the threaded sleeve 307 drives the U-shaped plate 309 and the circular plate 304 to move to the right through the screw 308, opening the right side of the filter cylinder 103. The circular plate 304 drives the scraper 302 to slide to the right through the bushing 301. The scraper 302 pushes the garbage and gravel in the filter cylinder 103 to the right and drops them into the box II 108 for collection. At the same time, it scrapes away the impurities on the inner wall of the filter cylinder 103 and the multiple scrapers 207.
