Description

Technical Field

[0001] The invention relates to the technical field of sludge cleaning, in particular to sewage treatment sludge cleaning equipment. Background Art

[0002] During the sewage treatment process, thick sludge accumulates at the bottom of the sedimentation tank, necessitating regular cleaning. Some sedimentation tanks are small, making manual cleaning with traditional handheld tools time-consuming and labor-intensive. Existing sludge cleaning equipment often uses a slurry flushing method, making it difficult to directly clean the deposited sludge. This increases the complexity of subsequent sludge treatment processes and can cause sludge splashing, disrupting normal cleaning operations. Therefore, a sewage treatment sludge cleaning device was proposed to address these issues. Summary of the Invention

[0022] See also Figure 1-5 As shown, a sewage treatment sludge cleaning equipment includes an L-shaped intercalating plate 1, a mud surface sliding ring plate 2, a rotary excavation and pushing pipe 3, an outer cone cover 5, a rotating pipe 12 and an inner cone cover 14. The bottom of the outer cone cover 5 is annularly distributed and connected with a group of rotary excavation and pushing pipes 3, and the cover edge of the outer cone cover 5 and the cover edge of the inner cone cover 14 are welded together. A mud storage and extrusion space is formed between the outer cone cover 5 and the inner cone cover 14, and the middle part of the outer cone cover 5 is connected and installed with the rotating pipe 12, and a shoveling and pushing sludge structure space is formed between the mud surface sliding ring plate 2 and the L-shaped intercalating plate 1. The bottom end port of each rotary excavation and pushing pipe 3 is located inside the formed shoveling and pushing sludge structure space, and the top port of the rotating pipe 12 is rotatably installed with one end of a sludge outlet hose 8, and the middle part of the rotating pipe 12 is fixedly connected to the inside of the hollow shaft of the hollow shaft servo motor 7, and the hollow shaft servo motor 7 is fixedly installed in the middle position of the top of the digitimeter plate 6.

[0023] A large-diameter bearing 4 is assembled in the middle of the outer cone cover 5, and the large-diameter bearing 4 is fixedly connected to the corresponding part of the strip block 9. The bottom end of the strip block 9 is fixedly connected to the top of the L-shaped intercalation plate 1, and hand-held rods 10 are installed on both sides of the top of the strip block 9. One side of the strip block 9 is fixedly connected to one side of the middle of the figure plate 6, and a lithium battery module 11 is installed inside the rectangular groove 910 on the other side of the strip block 9.

[0024] The bottom surfaces of both ends of the "X" plate 6 are flush with the surface of the top of the mud surface sliding ring plate 2.

[0025] The rotary extrusion and pushing pipe 3 is a spiral structure, and the bottom end of the rotary extrusion and pushing pipe 3 is inclined inward.

[0026] The top end of the rotating tube 12 is rotatably mounted with one end of a sludge outlet hose 8 , and the middle portion of the rotating tube 12 is fixedly connected to the inside of the hollow shaft of the hollow shaft servo motor 7 , which is fixedly mounted in the middle position of the top of the cross plate 6 .

[0027] The specific steps are as follows: Step 1: The bottom planes at both ends of the cross plate 6 and the mud surface sliding ring plate 2 are in contact with the surface of the sludge layer, and the L-shaped intercalation plate 1 is inserted into the sludge layer. This can not only place the entire support on the sludge layer, but also enable the bottom planes at both ends of the cross plate 6 and the mud surface sliding ring plate 2 to slide on the surface of the sludge layer, thereby solving the problem of moving the sludge cleaning equipment; Step 2: When the lithium battery module 11 supplies power to the hollow shaft servo motor 7, the hollow shaft servo motor 7 drives the connected rotating tube 12 and the interconnected inner cone cover 14 and outer cone cover 5 to rotate synchronously at high speed, so that a group of rotary extrusion and pushing pipes 3 located at the bottom of the outer cone cover 5 rotate at high speed to perform rotary excavation on the sludge in the limited area between the mud surface sliding ring plate 2 and the L-shaped intercalation plate 1; Step 3: Since the sludge is a large amount of sediment, it is not mud when it enters the rotary extrusion and pushing tube 3. Therefore, when the rotary extruded sludge enters the outer cone cover 5 through the rotary extrusion and pushing tube 3, a conical sludge storage and squeezing space is formed between the inner cone cover 14 and the outer cone cover 5. The sludge is continuously shoveled into the sludge storage and squeezing space, so that the sludge entering the sludge storage and squeezing space is pushed and discharged outward along the inside of the rotating tube 12 connected thereto, wherein the rotary extrusion and pushing tube 3 continuously rotates to shovel into the sludge to form a continuous pushing and moving force; Step 4: While the rotary drilling is being performed to clean the sludge, the operator holds the hand-held rod 10 and pushes it to move left and right or forward and backward. The thickness of the sludge-pushing structure space formed between the mud surface sliding ring plate 2 and the L-shaped interlayer plate 1 is used as the layer thickness benchmark, and the sludge is cleaned layer by layer. Compared with the existing technology, the differences are: 1. The sludge is squeezed into the outer cone cover 5 by a set of high-speed rotating rotary extrusion and pushing pipes 3, which can form a continuous squeezing force and form a sludge storage and squeezing space between the outer cone cover 5 and the inner cone cover 14. The sludge excavated by rotary extrusion can be discharged from the rotating pipe 12, realizing the function of integrated rotary excavation and drainage. Second, the rotary extrusion and pushing tube 3 is a spiral structure, and the bottom end of the rotary extrusion and pushing tube 3 is tilted inward, which can effectively avoid being thrown out by the interference of centrifugal force and ensure the effectiveness of the rotary extrusion and pushing tube 3 in continuous rotary excavation; 3. A shoveling and pushing sludge structure space is formed between the mud surface sliding ring plate 2 and the L-shaped intercalating plate 1, which plays a role in limiting the space to be excavated by a group of rotary excavation and pushing pipes 3 distributed in an annular manner, avoiding the splashing of rotary excavation mud, and facilitating the orderly rotary excavation and cleaning of the sludge deposition layer layer by layer.
