Description

Technical Field

[0001] This utility model relates to the field of sewage tank cleaning technology, and more specifically, to a cleaning device for liquid sewage tanks with high sealing performance. Background Technology

[0002] During engineering construction, it is often necessary to discharge sewage into sewage tanks for cleaning. If the sludge on the bottom surface of the sewage tank is not cleaned for a long time, it will accumulate and mix together. Its own weight increases, and it cannot be displaced by the impact of water flow, making it difficult to clean the sludge. If the sludge is not cleaned for a long time, it will affect the normal use of the sewage tank.

[0003] A search revealed that Chinese patent application CN 109432834 A discloses a sewage tank cleaning device, including a support frame with a sewage tank mounted on it; a rectangular sewage trough on one side of the bottom of the sewage tank, with a sludge crushing component at the bottom of the rectangular sewage trough; vertical frames on both sides of the sewage tank, with a lifting component inside the vertical frames; the lifting component is connected to a horizontal frame located between the two vertical frames; and a translation component is located inside the horizontal frame, connected to a scraper. However, this device still has the following drawbacks:

[0004] (1) In the above patent documents, a sludge scraper is used to clean the sludge attached to the inner wall of the sewage tank. During the cleaning process, some sludge will adhere to the outer wall of the sludge scraper, which will reduce the cleaning effect. After the cleaning work is completed, the sludge scraper still needs to be cleaned, which increases the labor intensity of the staff.

[0005] In the aforementioned patent document, water is discharged to the next treatment unit through an outlet pipe, and then the sludge is further cleaned. However, since the amount of sludge deposited in the sewage is uncontrollable and the height of the outlet pipe is fixed and cannot be adjusted, the sludge may be discharged along with the sewage or too much water may remain in the sewage tank during drainage, which reduces the cleaning quality.

[0006] Therefore, we have made improvements to this and proposed a cleaning device for liquid sewage tanks with high sealing performance. Utility Model Content

[0007] The purpose of this invention is to use a scraper to clean the sludge adhering to the inner wall of the sewage tank. During the cleaning process, some sludge will adhere to the outer wall of the scraper, which will reduce the cleaning effect. After the cleaning work is completed, the scraper still needs to be cleaned, which increases the labor intensity of the workers. Water is discharged to the next treatment unit through the outlet pipe for further cleaning of sludge. Since the amount of sludge deposited in the sewage is uncontrollable and the height of the outlet pipe is fixed and cannot be adjusted, sludge may be discharged along with the sewage or too much water may remain in the sewage tank, which reduces the cleaning quality.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A cleaning device for a highly airtight liquid sewage tank includes a support frame, a mounting bracket fixedly connected to the top wall of the support frame, and a sewage tank fixedly connected to the top wall of the support frame, and further includes:

[0010] A drainage assembly is fixedly connected to the top wall of a sewage tank and is used to pump out sewage that has been left to stand in the sewage tank. The drainage assembly includes a lifting hydraulic cylinder fixedly connected to the top wall of the sewage tank, a water pump fixedly connected to the telescopic end of the lifting hydraulic cylinder, a drainage pump fixedly connected to the top of the water pump, and an outlet pipe fixedly connected to the top wall of the drainage pump. The bottom end of the water pump is flush with the telescopic end of the lifting hydraulic cylinder, and the drainage pump is sleeved on the outer wall of the lifting hydraulic cylinder.

[0011] The sludge removal component is slidably connected to the inner wall of the sewage tank and is used to remove sludge adhering to the inner wall of the sewage tank.

[0012] The discharge assembly is rotatably connected to the side wall of the sewage tank and is used to discharge the cleaned sludge.

[0013] A water storage component, fixedly connected to the bottom wall of the sewage tank, is used to store detergent for cleaning.

[0014] The cleaning assembly is fixedly connected to the top wall of the sewage tank and is used for cleaning and sludge removal components.

[0015] As a preferred technical solution of this utility model, the sludge removal component includes a sealing scraper slidably connected to the inner wall of the sewage tank, a motor fixedly connected to the top wall of the mounting frame, a screw fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the outer wall of the screw, and a transmission frame fixedly connected to the bottom wall of the threaded sleeve. The threaded sleeve drives the sealing scraper to move along the inner wall of the sewage tank through the transmission frame. The motor and the transmission frame are symmetrically distributed about the central axis of the sewage tank.

[0016] As a preferred technical solution of this utility model, the excretion assembly includes an excretion hopper fixedly connected to the side wall of the sewage tank, a sealing door plate rotatably connected to the side wall of the sewage tank, a first magnetic block fixedly connected to the outer wall of the sewage tank, a second magnetic block fixedly connected to the outer wall of the sealing door plate, and a locking bolt slidably connected to the outer wall of the sewage tank. After the sealing door plate is rotated open, the excretion hopper is connected to the inside of the sewage tank, and the locking bolts are symmetrically distributed about the central axis of the sewage tank.

[0017] As a preferred technical solution of this utility model, the water storage component includes a water tank fixedly connected to the bottom wall of the sewage tank, a one-way valve fixedly connected to the outer wall of the water tank, a water pump fixedly connected to the inner wall of the water tank, and a water delivery pipe fixedly connected to the outer wall of the water tank. The one-way valve, the water pump, and the water delivery pipe are symmetrically distributed about the central axis of the water tank, and the water delivery pipe is internally connected to the water pump.

[0018] As a preferred technical solution of this utility model, the cleaning assembly includes a water spray pipe fixedly connected to the top wall of the sewage tank and an electromagnetic water spray head fixedly connected to the bottom wall of the water spray pipe. The electromagnetic water spray heads are evenly arranged about the bottom wall of the water spray pipe and are connected to the inside of the water spray pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the solution of this utility model:

[0021] 1. A motor drives a screw to rotate, which in turn drives a threaded sleeve, a transmission frame, and a sealing scraper to move along the screw axis. Simultaneously, the sealing scraper scrapes off the sludge from the inner wall of the sewage tank and pushes it towards the discharge hopper, where it falls into a designated loading container. Then, a water pump is activated to draw detergent from the tank into the spray pipe. The detergent is sprayed out through an electromagnetic spray head to form a high-speed water flow. The electromagnetic spray head is controlled to adjust the water flow's thickness and spray range, effectively cleaning the sludge remaining on the surface of the sealing scraper and the inner wall of the sewage tank. This method effectively removes residual sludge from the sealing scraper surface and the inner wall of the sewage tank, solving the problem of existing technologies where scrapers are used to clean sludge adhering to the inner wall of the sewage tank. During the cleaning process, some sludge adheres to the outer wall of the scraper, reducing the cleaning effect. Furthermore, the scraper still needs to be cleaned after the cleaning work is completed, increasing the labor intensity of the workers.

[0022] 2. By using a lifting hydraulic cylinder to raise and lower the pumping pipe to a set height, the bottom of the pumping pipe is always higher than the height of the sludge deposited in the sewage. Then, the drainage pump is started to pump out the sewage and discharge it to the next treatment unit through the extended outlet pipe. This achieves the pumping out of sewage at any liquid level in the sewage tank. It solves the problem in the existing technology that uses an outlet pipe to discharge water to the next treatment unit and then further cleans the sludge. Because the amount of sludge deposited in the sewage is uncontrollable and the height of the outlet pipe is fixed and cannot be adjusted, sludge may be discharged along with the sewage or too much water may remain in the sewage tank, which reduces the quality of cleaning.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 and Figure 3 As shown, this embodiment proposes a cleaning device for a highly airtight liquid sewage tank, including a support bracket 1, a mounting bracket 11 fixedly connected to the top wall of the support bracket 1, and a sewage tank 12 fixedly connected to the top wall of the support bracket 1, and further including:

[0031] A drainage assembly is fixedly connected to the top wall of the sewage tank 12 and is used to pump out the sewage that has been left to stand in the sewage tank 12. The drainage assembly includes a lifting hydraulic cylinder 4 fixedly connected to the top wall of the sewage tank 12, a water pump 41 fixedly connected to the extension end of the lifting hydraulic cylinder 4, a drainage pump 42 fixedly connected to the top of the water pump 41, and an outlet pipe 43 fixedly connected to the top wall of the drainage pump 42. The bottom end of the water pump 41 is flush with the extension end of the lifting hydraulic cylinder 4. The drainage pump 42 is sleeved on the outer wall of the lifting hydraulic cylinder 4. The lifting hydraulic cylinder 4 is controlled to drive the water pump 41 to rise and fall to a set height, so that the bottom opening of the water pump 41 is higher than the height of the sludge deposited in the sewage. The drainage pump 42 is started, and the drainage pump 42 pumps the sewage that has been left to stand out from the sewage tank 12 and discharges it to the next treatment unit through the extended outlet pipe 43, thus completing the pumping out of the sewage in the sewage tank 12.

[0032] The sludge removal component is slidably connected to the inner wall of the sewage tank 12 and is used to remove the sludge adhering to the inner wall of the sewage tank 12.

[0033] The discharge assembly is rotatably connected to the side wall of the sewage tank 12 and is used to discharge the cleaned sludge;

[0034] A water storage component is fixedly connected to the bottom wall of the sewage tank 12 and is used to store detergent for cleaning.

[0035] The cleaning component is fixedly connected to the top wall of the sewage tank 12 and is used for cleaning and sludge removal components.

[0036] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the sludge removal assembly further includes a sealing scraper 2 slidably connected to the inner wall of the sewage tank 12, a motor 21 fixedly connected to the top wall of the mounting frame 11, a screw 22 fixedly connected to the output end of the motor 21, a threaded sleeve 23 threadedly connected to the outer wall of the screw 22, and a transmission frame 24 fixedly connected to the bottom wall of the threaded sleeve 23. The threaded sleeve 23 drives the sealing scraper 2 to move along the inner wall of the sewage tank 12 through the transmission frame 24. The motor 21 and the transmission frame 24 are symmetrically distributed about the central axis of the sewage tank 12. The motor 21 drives the screw 22 to rotate, so that the threaded sleeve 23 drives the transmission frame 24 and the sealing scraper 2 to move along the axial direction of the screw 22. When the sealing scraper 2 moves along the inner wall of the sewage tank 12 towards the discharge hopper 3, it scrapes off the sludge on the inner wall of the sewage tank 12, so that the sludge is discharged from the sewage tank 12 through the discharge hopper 3 and falls into the set carrying container, thus completing the cleaning and discharge of the sludge in the sewage tank 12.

[0037] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the discharge assembly further includes a discharge hopper 3 fixedly connected to the side wall of the sewage tank 12, a sealing door 31 rotatably connected to the side wall of the sewage tank 12, a first magnetic block 32 fixedly connected to the outer wall of the sewage tank 12, a second magnetic block 33 fixedly connected to the outer wall of the sealing door 31, and a locking bolt 34 slidably connected to the outer wall of the sewage tank 12. After the sealing door 31 is rotated open, the discharge hopper 3 is connected to the inside of the sewage tank 12. The locking bolt 34 is symmetrically distributed about the central axis of the sewage tank 12. Pulling out the locking bolt 34 unlocks the sealing door 31. Rotating the sealing door 31 causes the first magnetic block 32 and the second magnetic block 33 to stick together and adhere to each other, completing the preparation work before discharging sludge.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the water storage component further includes a water tank 5 fixedly connected to the bottom wall of the sewage tank 12, a one-way valve 51 fixedly connected to the outer wall of the water tank 5, a water pump 52 fixedly connected to the inner wall of the water tank 5, and a water delivery pipe 53 fixedly connected to the outer wall of the water tank 5. The one-way valve 51, the water pump 52, and the water delivery pipe 53 are symmetrically distributed about the central axis of the water tank 5. The water delivery pipe 53 is internally connected to the water pump 52. Detergent is added to the water tank 5 through the one-way valve 51, and the water pump 52 is started to draw the detergent inside the water tank 5 into the spray pipe 6 through the water delivery pipe 53.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the cleaning assembly further includes a water spray pipe 6 fixedly connected to the top wall of the sewage tank 12 and an electromagnetic water spray head 61 fixedly connected to the bottom wall of the water spray pipe 6. The electromagnetic water spray heads 61 are evenly arranged around the bottom wall of the water spray pipe 6 and are connected to the inside of the water spray pipe 6. The detergent is sprayed out as a high-speed water flow through the electromagnetic water spray head 61. The coarseness and spray range of the high-speed water flow can be adjusted by controlling the electromagnetic water spray head 61. The high-speed water flow cleans the sludge remaining in the sealing scraper 2 and the sewage tank 12. The cleaned sludge residue is discharged from the discharge hopper 3, thus completing the cleaning of the residual sludge on the surface of the sealing scraper 2 and the inner wall of the sewage tank 12.

[0040] Specifically, when using this device: wastewater is discharged into the wastewater tank 12 and left to stand for a period of time. When sludge accumulates on the inner wall and bottom of the wastewater tank 12, the lifting hydraulic cylinder 4 is controlled to raise and lower the pumping pipe 41 to a set height, so that the bottom opening of the pumping pipe 41 is higher than the height of the sludge deposited in the wastewater. The drainage pump 42 is then started, and the drainage pump 42 pumps the settled wastewater out of the wastewater tank 12 and discharges it to the next treatment unit through the extended outlet pipe 43, completing the drainage of wastewater from the wastewater tank 12. The lifting hydraulic cylinder 4 is then controlled to reset the pumping pipe 41, the locking bolt 34 is pulled out to unlock the sealing door plate 31, and the sealing door plate 31 is rotated to make the first magnetic block 32 and the second magnetic block 33 stick together and adhere to each other, completing the preparation work before discharging the sludge. The motor 21 is controlled to drive the screw 22 to rotate, so that the threaded sleeve 23 drives the transmission frame 24. The sealing scraper 2 moves along the axis of the screw 22. When the sealing scraper 2 moves along the inner wall of the sewage tank 12 toward the discharge hopper 3, it scrapes off the sludge on the inner wall of the sewage tank 12, so that the sludge is discharged from the sewage tank 12 through the discharge hopper 3 and falls into the set carrying container, thus completing the cleaning and discharge of the sludge in the sewage tank 12. Detergent is added to the water tank 5 through the one-way valve 51, and the water pump 52 is started to pump the detergent in the water tank 5 into the spray pipe 6 through the water supply pipe 53. The detergent is sprayed out as a high-speed water jet through the electromagnetic spray head 61. The coarseness and spray range of the high-speed water jet can be adjusted by controlling the electromagnetic spray head 61. The high-speed water jet cleans the sludge remaining in the sealing scraper 2 and the sewage tank 12. The cleaned sludge residue is discharged from the discharge hopper 3, thus completing the cleaning of the sludge remaining on the surface of the sealing scraper 2 and the inner wall of the sewage tank 12.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
