Description

Technical Field

[0001] This invention relates to the field of septic tank technology, and more specifically to a septic tank cleaning device. Background Technology

[0002] Domestic sewage can be recycled through processes such as fermentation, filtration and sedimentation. However, most septic tanks currently only have two filter layers, which is not thorough and requires multiple filtrations, thus increasing the workload of filtration.

[0003] To address the aforementioned problems, Chinese Patent Publication No. CN218232164U discloses a filtration device for septic tanks, comprising a septic tank, an inlet, a storage chamber, a filtration chamber, a clarification chamber, a drain outlet, a crushing component, and a filtration component. The inlet is located on top of the septic tank, the storage chamber is located inside the septic tank and below the inlet, the filtration chamber is located inside the septic tank and to one side of the storage chamber, the clarification chamber is located inside the septic tank and on the side of the filtration chamber away from the storage chamber, the drain outlet is located on top of the septic tank and to one side of the clarification chamber, the crushing component is located inside the storage chamber, and the filtration component is located inside the septic tank. This device performs multiple stages of filtration of feces through the filtration component, thereby improving the filtration effect of the septic tank, i.e., improving the filtration efficiency and quality of feces.

[0004] The above-mentioned device has the following problems in actual use: the device discharges fecal liquid through the drain outlet, so the feces and liquid water are still mixed together. If it is necessary to achieve the single recycling of feces and liquid water, then the fecal liquid needs to be separated into solid and liquid, which increases the workload and causes unnecessary trouble for the workers. Summary of the Invention

[0005] This invention provides a septic tank cleaning device to solve the problem that existing filtration devices cannot achieve solid-liquid separation when fecal liquid is discharged.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a septic tank cleaning device, comprising a discharge box with an inlet and an outlet, and further comprising a discharge pipe, a guide pipe, a drain pipe, a filter cloth, and a filtration mechanism; the discharge pipe is connected to the inlet; the guide pipe and the drain pipe are both fixedly connected to the discharge box and are in contact with each other; the filter cloth is fixedly connected to the drain pipe, and the free end of the discharge pipe is in contact with the filter cloth; the filtration mechanism comprises a fixed block, a bottom shaft, a bottom plate, a first torsion spring, a moving block, a scraper block, a pusher block, a through hole on the discharge pipe, a rotating hole on the fixed block, a drive assembly for driving the moving block to reciprocate along the length direction of the discharge pipe, and a moving hole on the discharge pipe; the fixed block is fixedly connected to the through hole; the bottom shaft is rotatably connected to the rotating hole; the bottom plate is fixedly connected to the bottom shaft; the two ends of the first torsion spring are respectively connected to the bottom shaft and the rotating hole; the moving block is slidably connected to the moving hole; the scraper block and the pusher block are both fixedly connected to the moving block; the scraper block is in contact with the filter cloth; the bottom plate is located on the movement trajectory of the pusher block.

[0007] The principle and advantages of this scheme are: The liquid feces are introduced into the inlet and outlet pipes through the inlet, allowing the liquid feces to flow through the filter cloth for filtration. This allows the liquid water to flow through the filter cloth into the inlet and outlet pipes, while the solid feces remain on the filter cloth, achieving initial solid-liquid separation and preparing for further separation.

[0008] While solid feces remain on the filter cloth, the moving block, through the scraper, propels the solid feces towards the bottom plate. As the solid feces approach the bottom plate, the pushing block pushes the bottom plate, causing it to rotate and allowing the solid feces to move into the conduit. This process is repeated, ensuring sufficient flow of solid feces through the conduit, thus achieving separate collection of solid feces.

[0009] Through the aforementioned process, liquid water and solid feces were collected separately, ensuring the proper handling of these substances.

[0010] 3. The scraper block's contact with the filter cloth is designed to push all solid feces into the conduit, ensuring more thorough and complete collection. It also cleans the filter cloth, thereby improving its filtration efficiency and quality.

[0011] Furthermore, it also includes a linkage component; the linkage component includes a linkage block, a number of fragments equidistantly arranged along the length direction of the linkage block, a chamber opened in the fixed block, a slide groove opened on the chamber, and a power unit for driving the linkage block to reciprocate along the length direction of the chamber; the linkage block is slidably connected to the chamber; the fragments are fixedly connected to the linkage block and slidably connected to the slide groove.

[0012] During the movement of the liquid feces towards the filter cloth, the reciprocating motion of the fragments cuts and breaks down the liquid feces, reducing the volume of solid feces within the liquid feces and thus facilitating better recycling of solid feces.

[0013] Furthermore, the linkage component also includes a linkage part; the linkage part also includes a number of flexible blocks equidistantly arranged along the length direction of the moving block; the flexible blocks are fixedly connected to the moving block, and the flexible blocks are located between two adjacent fragments.

[0014] By having the fragments reciprocate along the length of the fixed block, and the moving block driving the flexible block to move synchronously, the flexible block can clean up solid feces stuck between adjacent fragments, thereby reducing the amount of solid feces adhering between adjacent fragments. Through this movement, the fragments can more efficiently and thoroughly crush solid feces, thus improving the crushing efficiency and quality.

[0015] Furthermore, it also includes a feeding section; the feeding section includes a feeding block, a mesh plate, a feeding hole opened on the fixed block, and a drive unit for driving the feeding block to make vertical reciprocating motion; the feeding block is slidably connected to the feeding hole; the mesh plate is fixedly connected to the feeding block.

[0016] During the flow of liquid feces within the discharge pipe, the vertical reciprocating motion of the mesh plate slows down the discharge speed, thereby enabling the filter cloth to efficiently and systematically separate the liquid water. Furthermore, as the liquid feces flow through the mesh plate, the plate also cuts the solid feces, reducing its volume and preparing it for further crushing.

[0017] Furthermore, it also includes an auxiliary section; the auxiliary section includes a guide rod, a long block, auxiliary units symmetrically arranged on both sides of the conduit along the width direction of the conduit, and a motion unit for driving the long block to perform vertical reciprocating motion; the guide rod is fixedly connected to the discharge box; the long block is slidably connected to the guide rod; the auxiliary unit includes an auxiliary shaft, an auxiliary plate, a second torsion spring, and an auxiliary block; the auxiliary shaft is rotatably connected to the inner wall of the conduit; the auxiliary plate is fixedly connected to the auxiliary shaft; the two ends of the second torsion spring are respectively connected to the auxiliary shaft and the conduit; the auxiliary block is fixedly connected to the long block; the auxiliary plate is located on the motion trajectory of the auxiliary block.

[0018] The auxiliary plate is designed to initially collect the feces that fall into the conduit. Once the amount of feces reaches a certain weight, the feces' own weight pushes the auxiliary plate, causing the feces to fall out of the conduit and complete the final collection.

[0019] The auxiliary block is designed to work in alternating motion with the scraper. After the scraper pushes the feces into the conduit, the auxiliary block assists in pushing the auxiliary plate to rotate, thus ensuring that when a certain amount of feces accumulates, all of it will fall out of the conduit.

[0020] Furthermore, the auxiliary part also includes a cleaning unit; the cleaning unit includes a guide block, a vertical block, a side block, a sleeve symmetrically arranged along the width direction of the guide tube, and a power component for driving the vertical block to perform vertical reciprocating motion; the guide block is fixedly connected to the fixed block; the vertical block is slidably connected to the guide block; the side block is fixedly connected to the vertical block; the sleeve is fixedly connected to the side block, the auxiliary block is attached to the inner wall of the sleeve, and the auxiliary block can slide in and out of the sleeve.

[0021] The sleeve is designed to clean the solid feces adhering to the auxiliary block through its vertical reciprocating motion. This ensures that all solid feces fall out of the conduit and reduces the impact of feces adhesion, thereby enhancing the pushing effect and efficiency of the auxiliary block.

[0022] Furthermore, the drive assembly includes a first screw, a slide bar, a first nut seat, and a drive unit for driving the first screw to rotate; the first screw is rotatably connected to the discharge box; the slide bar is fixedly connected to the discharge box; the first nut seat is threadedly connected to the first screw and slidably connected to the slide bar; and the first nut seat is fixedly connected to the moving block.

[0023] During the rotation of the first screw, the first nut seat reciprocates along the length of the slide rod. During the movement of the first nut seat, the moving block moves synchronously.

[0024] Furthermore, the power unit includes a cam and a spring; the cam is fixedly connected to the first screw; the linkage block is slidably connected to the discharge pipe, and the cam abuts against the linkage block; the two ends of the spring are respectively connected to the linkage block and the chamber.

[0025] During the rotation of the first screw, the cam rotates synchronously. During cam rotation, when the cam's protrusion abuts against the linkage block, the linkage block moves away from the first screw, compressing the spring; when the cam's protrusion no longer abuts against the linkage block, the linkage block resets under the spring's action, moving closer to the first screw. Therefore, the linkage block can reciprocate along the length of the fixed block.

[0026] Furthermore, the driving unit is a connecting block; the two ends of the connecting block are fixedly connected to the feeding block and the vertical block, respectively.

[0027] During the movement of the vertical block, the vertical block drives the material feeding block to move synchronously through the connecting block.

[0028] Furthermore, the motion unit includes a second screw, a second nut seat, and a moving component for driving the second screw to rotate; the second screw is rotatably connected to the discharge box; the second nut seat is threadedly connected to the second screw, and the second nut seat is fixedly connected to the long block.

[0029] During the rotation of the second screw, the second nut seat drives the long block to reciprocate along the length of the guide rod. Attached Figure Description

[0050] The drive unit includes a first bevel gear 36 and a second bevel gear 37; the first bevel gear 36 is fixedly connected to the first screw 26; the second bevel gear 37 is fixedly connected to the second screw 31; the first bevel gear 36 and the second bevel gear 37 mesh.

[0051] The moving part is a servo motor 38; the servo motor 38 is fixedly connected to the discharge pipe 2, and the output shaft of the servo motor 38 is fixedly connected to the second screw 31.

[0052] Specific implementation process: The fecal liquid is introduced into the discharge pipe 2 through the inlet, and the servo motor 38 is started. During the rotation of the servo motor 38, the output shaft of the servo motor 38 drives the second screw 31 to rotate. During the rotation of the second screw 31, the second screw 31 drives the first screw 26 to rotate through the meshing of the first bevel gear 36 and the second bevel gear 37. During the rotation of the first screw 26, the cam 29 rotates synchronously.

[0053] During the rotation of cam 29, when the protrusion of cam 29 abuts against the linkage block 12, the linkage block 12 moves away from the position of the first screw 26, and the spring 30 is compressed; when the protrusion of cam 29 no longer abuts against the linkage block 12, the linkage block 12 returns to its original position under the action of the spring 30, and the linkage block 12 moves towards the position of the first screw 26. Therefore, the linkage block 12 can reciprocate along the length direction of the fixed block 6.

[0054] During the movement of the linkage block 12, the first rack 35 moves synchronously. During the movement of the first rack 35, the first gear 33 drives the power shaft to rotate through the meshing of the first rack 35 and the first gear 33. During the rotation of the power shaft, the second rack can perform vertical reciprocating motion along the length direction of the guide block 22 through the meshing of the second gear 34 and the second rack. During the movement of the second rack, the second rack drives the feeding block 15 to move synchronously through the connecting block.

[0055] During the movement of the feed block 15, the screen plate 16 moves synchronously. Therefore, during the flow of liquid feces in the discharge pipe 2, the vertical reciprocating motion of the screen plate 16 slows down the discharge speed of the liquid feces, thereby enabling the filter cloth 5 to efficiently and orderly separate the liquid water. Furthermore, as the liquid feces flow through the screen plate 16, the screen plate 16 can also cut the solid feces, thereby reducing the volume of the solid feces and preparing it for further crushing.

[0056] After the liquid feces are broken down by the mesh plate 16, the liquid feces flow through the filter cloth 5 for filtration, and then the liquid water flows into the inlet and outlet pipe 4 through the filter cloth 5. The solid feces remain on the filter cloth 5 to achieve preliminary solid-liquid separation, thus preparing for further separation.

[0057] During the rotation of the first screw 26, the first nut seat 28 drives the moving block 9 to move synchronously along the length of the slide plate. Therefore, while the solid feces are retained on the filter cloth 5, the moving block 9, through the scraper 10, drives the solid feces towards the position of the bottom plate 8; and when the solid feces are about to approach the bottom plate 8, the pusher 11 pushes the bottom plate 8, thereby causing the bottom plate 8 to rotate, so that the solid feces can move into the conduit 3. Repeating the above process, the solid feces are allowed to flow fully through the conduit 3, thus achieving the separate collection of solid feces.

[0058] Through the aforementioned process, liquid water and solid feces were collected separately, ensuring the proper handling of these substances.

[0059] The scraper 10 is positioned to abut against the filter cloth 5 to push all solid feces into the conduit 3, thus ensuring more thorough and comprehensive collection of feces. It also cleans the filter cloth 5, thereby improving its filtration efficiency and quality.

[0060] As the liquid feces moves toward the location of the filter cloth 5, the linkage block 12 drives the fragments 13 to move synchronously. Through the reciprocating motion of the fragments 13, the fragments 13 can cut and break the liquid feces, thereby reducing the volume of solid feces within the liquid feces, thus facilitating better recycling of solid feces.

[0061] By having the fragments 13 reciprocate along the length of the fixed block 6, and the movable block 9 drive the flexible block 14 to move synchronously, the flexible block 14 can clean up the solid feces stuck between adjacent fragments 13, thereby reducing the amount of solid feces adhering between adjacent fragments 13. Through the above movement, the fragments 13 can more efficiently and thoroughly crush the solid feces, thus improving the crushing efficiency and quality of the fragments 13.

[0062] The auxiliary plate 20 is designed to initially collect the feces that fall into the conduit 3 until the amount of feces reaches a certain weight. Then, the feces themselves push the auxiliary plate 20, causing the feces to fall out of the conduit 3 and complete the final collection.

[0063] During the movement of the second screw 31, the second nut seat 32 drives the long block 18 to move synchronously along the length of the guide rod 17. During the movement of the long block 18, the auxiliary block 21 moves synchronously. The auxiliary block 21 is designed to move alternately with the scraper 10. That is, after the scraper 10 pushes the feces into the inlet pipe 3, the auxiliary block 21 assists in pushing the auxiliary plate 20 to rotate, thereby ensuring that when the feces accumulate to a certain amount, all the feces can fall out of the pipe 3.

[0064] During the movement of the second rack, the second rack drives the sleeve 25 to move synchronously via the side block 24. The sleeve 25 is designed to clean the solid feces adhering to the auxiliary block 21 through its vertical reciprocating motion. This ensures that all solid feces can fall out of the conduit 3, while also reducing the impact of feces adhesion, thereby enhancing the pushing effect of the auxiliary block 21 and improving its pushing efficiency.

[0065] In summary, solid-liquid separation of fecal liquid was achieved, thereby significantly enhancing the treatment effect of fecal liquid and paving the way for further treatment of the separated liquid water and solid feces.
