Description

Technical Field

[0001] This application relates to the technical field of dehumidification in cigarette manufacturing workshops, and in particular to a water tank cleaning device and water tank. Background Technology

[0002] Cigarette factories typically install dehumidification and odor removal systems in their power workshops to reduce the temperature, dust, and odor of exhaust gases, thereby lowering air pollution and achieving cleaner production. This not only improves the environment but also enhances the company's image. Currently, during the operation of these systems, tobacco dust and impurities from the flue gas are carried from the cyclone separator into the dehumidification pool. Therefore, the liquid in the dehumidification pool contains a large amount of tobacco dust and impurities. To ensure the proper functioning of the system, it is necessary to clean the tobacco dust and impurities from the dehumidification pool.

[0003] Currently, the main method for cleaning tidal pools is to manually use nets to remove tobacco dust and impurities. This operation is not only time-consuming but also incomplete. Utility Model Content

[0004] This application provides a water tank cleaning device and a water tank that can automatically clean up smoke and impurities in the water tank, thereby saving manpower and improving the cleaning effect.

[0005] This application provides a water tank cleaning device for cleaning liquids within a water tank. The device includes a water supply pipe, a water pump, a filtration mechanism, and a sedimentation tank. The water supply pipe has an inlet end and an outlet end, with the inlet end extending into the interior of the water tank. The water pump is mounted on the water supply pipe and is used to draw liquid from the water tank. The filtration mechanism is located downstream of the water supply pipe and is used to filter impurities from the liquid output from the outlet end. The sedimentation tank is located downstream of the filtration mechanism and is used to collect the liquid output from the filtration mechanism. The sedimentation tank has a liquid drain outlet and a sludge drain outlet. The sludge drain outlet is located near the bottom of the sedimentation tank and is equipped with a sludge drain valve. The height of the liquid drain outlet is higher than that of the sludge drain outlet, allowing the liquid output from the liquid drain outlet to flow back into the water tank.

[0006] When cleaning the water in the pool is required, the water pump is started. The pump draws the liquid from the pool into the water supply pipe, which then flows through the pipe and exits at the outlet to the filtration unit. The filtration unit removes particulate matter from the liquid. The liquid, now free of particulate matter, is then discharged into the sedimentation tank. Small particles not filtered out by the filtration unit settle at the bottom of the tank. The liquid drain port on the sedimentation tank is used to drain the liquid, while the wastewater drain port is used to remove the sediment. During normal operation, the wastewater drain valve is closed. Because the liquid drain port is a certain distance from the bottom of the sedimentation tank and is higher than the wastewater drain port, impurities in the liquid settle below the drain port and are not discharged through it. The settled liquid flows back into the pool through the drain port. When too much impurity accumulates at the bottom of the sedimentation tank, the operator can open the wastewater drain valve to allow the impurities to flow out. The water tank cleaning device provided in this application can automatically clean the water tank, thereby saving manpower and improving the cleaning effect.

[0007] Optionally, the filtration mechanism includes a filter element, which comprises a frame and a filter screen. The area of ​​the filter screen is larger than the area of ​​the frame, and the edge of the filter screen is connected to the frame, forming a mesh bag with an open top. The outlet end of the water supply pipe is located above the filter screen. Water output from the outlet end flows into the mesh bag under gravity. The filter screen traps large particles of smoke in the liquid above the screen, and the liquid after removing the smoke continues to flow downward through the mesh of the filter screen, thus separating the smoke from the liquid. Furthermore, by setting the area of ​​the filter screen to be larger than the area of ​​the frame, a downward-hanging mesh bag can be formed. When liquid comes into contact with the filter screen and splashes, the sidewalls of the mesh bag can also filter the splashed liquid, thereby enhancing the filtration effect.

[0008] Optionally, the filtration mechanism also includes a rotating frame capable of rotating around a rotation axis; the number of filter elements is at least two, each connected to the rotating frame and arranged along the rotation direction of the frame; each filter element passes sequentially below the water outlet during the rotation of the frame. When the filter screen needs to be replaced, the operator can rotate the rotating frame to move the new filter element below the water outlet. Simultaneously, the old filter element moves out from below the water outlet, allowing the operator to replace the old filter screen while the cleaning device is operating. This not only does not interfere with the cleaning device's operation but also prevents the water outlet from occupying the operator's operating space for replacing the old filter screen, making the operation easier for the operator.

[0009] Optionally, the sedimentation tank has an opening at the top, located below the filter element. A support element is provided at the opening, and the support element has a drainage groove. Liquid filtered by the filter element can flow into the sedimentation tank through the drainage groove, and the bottom of the filter screen can contact the support element. By providing the support element, the drooping filter screen can be supported, preventing the filter screen from being torn due to excessive smoke or weight. For example, the support element includes multiple support rods, the ends of which are connected to the sedimentation tank. The support rods are spaced apart in a direction perpendicular to the filter element, and the space between two adjacent support rods forms a drainage groove.

[0010] Optionally, the sedimentation tank is equipped with a partition plate that divides the internal space into a first chamber and a second chamber. A support member is located at the opening above the first chamber, and the bottom of the partition plate has a notch, through which the first and second chambers are connected. When the operator needs to clean the impurities deposited at the bottom of the sedimentation tank with tools, the tools can be inserted into the sedimentation tank through the opening above the second chamber. Since the support member is only located at the opening of the first chamber, it will not obstruct the operator. Furthermore, because of the notch at the bottom of the partition plate, after inserting the tools into the second chamber, the operator can also insert the tools into the first chamber through the notch, thereby thoroughly cleaning the bottom of the sedimentation tank.

[0011] Optionally, at least one baffle plate is provided on the side wall of the first cavity. The baffle plate is connected to the sedimentation tank via a spring hinge, which provides a force to keep the baffle plate above the opening. The baffle plate can block liquid splashing in all directions, preventing liquid from splashing onto the ground and causing water accumulation. In addition, by connecting the baffle plate to the sedimentation tank via the spring hinge, the operator can fold the baffle plate and lock it with fasteners or buckles when the cleaning device is not in operation, for safekeeping.

[0012] Optionally, the water supply pipeline includes a pipe body and a tee pipe. The tee pipe has a first inlet, a second inlet, and an outlet. The outlet is connected to one end of the pipe body, and the other end of the pipe body is the outlet of the water supply pipeline. Both the first and second inlets are located in the liquid within the pool. The first inlet is near the bottom of the pool, and the second inlet is near the surface of the liquid. Specifically, in actual production, some of the soot and impurities in the liquid in the pool settle at the bottom, while some float on the surface, resulting in a significant amount of soot and impurities at both the bottom and the surface. This application, by setting up a tee pipe, allows water to be drawn from the bottom of the pool through the first inlet and from the surface through the second inlet, thus enabling more comprehensive cleaning of the liquid in the pool.

[0013] Optionally, a cylindrical body is provided on the second water inlet. The cylindrical body is vertically oriented, and its lower end is connected to the second water inlet. Multiple strip-shaped holes are provided on the side wall of the cylindrical body, each extending vertically and spaced apart sequentially along the circumference of the cylindrical body. The surface of the liquid in the pool lies within the length of the strip-shaped holes, and the length of the strip-shaped holes is greater than the change in the liquid level in the pool. By providing the cylindrical body and the strip-shaped holes, even when the liquid level in the pool changes, water on the surface can still enter the second water inlet through the strip-shaped holes, thus preventing soot from the liquid surface from being unable to enter the second water inlet due to changes in the liquid level. For example, the length of the strip-shaped holes is 40-60 cm.

[0014] Optionally, the water pump is a submersible pump, which is located inside the water tank. The external drain outlet of the sedimentation tank is connected to a drain pipe, and the outlet of the drain pipe is located above the water tank or extends into the water tank.

[0015] This application also provides a water tank, including any of the aforementioned cleaning devices.

[0016] Compared with the prior art, this utility model has the following beneficial effects:

[0017] The water tank cleaning device provided by this utility model can automatically draw liquid from the tank into the cleaning device by means of a water pump. A filtration mechanism can filter out large particles of smoke from the liquid. A sedimentation tank allows small particles of impurities in the liquid to settle at the bottom, thus automatically cleaning the smoke and impurities in the liquid, saving manpower and improving cleaning efficiency.

[0030] Currently, most cigarette factories' power workshops are equipped with dehumidification and odor removal systems. During operation, these systems carry tobacco dust and impurities from the flue gas from the cyclone separator into the dehumidification pool, resulting in a large amount of tobacco dust and impurities in the pool. To ensure the proper functioning of the system, the dehumidification pool needs to be cleaned. Currently, the main method for cleaning the pool is manual retrieval of tobacco dust and impurities using a net. This operation is not only time-consuming but also incomplete.

[0031] To address the aforementioned problems, this application provides a water tank cleaning device that can automatically clean up smoke and impurities in the water tank, thereby saving manpower and improving cleaning efficiency.

[0032] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below.

[0033] This application provides a pool cleaning device for cleaning liquids within a pool 100. (Reference) Figure 1 and Figure 2 The water tank cleaning device provided in this application includes a water supply pipe 1, a water pump 2, a filter mechanism 4, and a sedimentation tank 3. The water supply pipe 1 has an inlet end 11 and an outlet end 12. The inlet end 11 extends into the interior of the water tank 100, and the outlet end is located outside the water tank 100. The water pump 2 is mounted on the water supply pipe 1 and is used to pump liquid from the water tank 100. Along the liquid flow direction, the filter mechanism 4 is located downstream of the water supply pipe 1, and the sedimentation tank 3 is located downstream of the filter mechanism 4. The liquid output from the outlet end 12 can flow into the filter mechanism 4, which filters out particulate matter from the liquid output from the outlet end 12. The liquid discharged from the filter mechanism 4 can flow into the sedimentation tank 3, allowing residual impurities in the liquid to settle in the sedimentation tank 3. The sedimentation tank 3 has a liquid outlet 31 and a sewage outlet 32. The sewage outlet 32 ​​is located near the bottom of the sedimentation tank 3 and is equipped with a sewage valve. The height of the liquid outlet 31 is higher than that of the sewage outlet 32. After sedimentation and impurity removal, the liquid can flow back into the water tank 100 through the drain port 31. When the drain valve is opened, the impurities deposited at the bottom of the sedimentation tank 3 can be discharged from the drain port 32.

[0034] When cleaning is required in the water tank 100, the water pump 2 is started. The water pump 2 draws the liquid from the water tank 100 into the water supply pipe 1. The liquid then flows through the water supply pipe 1 and is discharged from the outlet 12 of the water supply pipe 1 to the filter mechanism 4. The filter mechanism 4 can filter and remove soot from the liquid. The liquid after removing soot is then discharged from the filter mechanism 4 into the sedimentation tank 3. Small particulate impurities in the liquid that were not filtered out by the filter mechanism 4 can settle at the bottom of the sedimentation tank 3. When the cleaning device is working normally, the drain valve on the drain outlet 32 ​​is closed. Since the height of the drain outlet 31 is a certain distance from the bottom of the sedimentation tank 3 and is higher than the drain outlet 32, impurities in the liquid will settle below the drain outlet 31 and will not be discharged from the drain outlet 31. The liquid after sedimentation and impurity removal flows back into the water tank 100 from the drain outlet 31. When too much impurity accumulates at the bottom of the sedimentation tank 3, the operator can open the drain valve to allow the impurities to flow out. The water tank cleaning device provided in this application can automatically clean the water tank 100, thereby saving manpower and improving the cleaning effect.

[0035] Optional, see reference Figure 3 The filtration mechanism 4 includes a filter element 41, which includes a frame 411 and a filter screen 412. The area of ​​the filter screen 412 is larger than the area of ​​the frame 411. The edge of the filter screen 412 is connected to the frame 411, and the filter screen 412 forms a mesh bag with an open top. (Reference) Figure 1 and Figure 2 ( Figure 1 and Figure 2 (Filter screen 412 not shown) The outlet 12 of the water supply pipe 1 is located above the filter element 41. Water output from the outlet 12 flows into the filter element 41 under gravity. The filter screen 412 traps large particles of smoke in the liquid above the filter screen 412. The liquid after removing the smoke continues to flow downward through the mesh of the filter screen 412, thus separating the smoke from the liquid. By setting the area of ​​the filter screen 412 to be larger than the area of ​​the frame 411, a downwardly suspended net bag can be formed. When the liquid comes into contact with the filter screen 412 and splashes, the sidewalls of the net bag can also filter the splashed liquid, thereby enhancing the filtration effect.

[0036] Optional, see reference Figure 4 The filtration mechanism 4 also includes a rotating frame 42, which is rotatable about a rotation axis. The number of filter elements 41 is at least two, each filter element 41 is connected to the rotating frame 42 and arranged along the rotation direction of the rotating frame 42. Each filter element 41 can pass sequentially below the water outlet 12 during the rotation of the rotating frame 42. For example, refer to... Figure 2 and Figure 4The number of filter elements 41 is two. The filter mechanism 4 also includes a fixed rod 43, the lower part of which is connected to the water tank 100, and a rotating frame 42 is rotatably connected to the top of the fixed rod 43, with the rotation axis of the rotating frame 42 being the center line of the fixed rod 43.

[0037] When filter screen 412 needs to be replaced, the operator can rotate the rotating frame 42 to rotate the new filter element 41 to below the water outlet 12. At the same time, the old filter element 41 is moved out from below the water outlet 12. This not only allows the old filter screen 412 to be replaced without affecting the normal operation of the cleaning device, but also prevents the water outlet 12 from occupying the operator's operating space for replacing the old filter screen 412, making the operation easier for the operator.

[0038] Optional, see reference Figure 5 The sedimentation tank 3 has an opening at the top, located below the filter element 41. A support member 34 is provided at the opening, and a drainage groove 35 is provided on the support member 34. Liquid filtered by the filter element 41 can flow into the sedimentation tank 3 through the drainage groove 35. The bottom of the filter screen 412 can contact the support member 34. By providing the support member 34, the bottom of the drooping filter screen 412 can be supported, preventing the filter screen 412 from being torn due to excessive smoke or weight. For example, the support member 34 includes multiple support rods 36, the ends of which are connected to the sedimentation tank 3. The support rods 36 are spaced apart in a direction perpendicular to the support rods 36, and the space between two adjacent support rods 36 forms a drainage groove 35, through which liquid filtered by the filter screen 412 can flow into the sedimentation tank 3.

[0039] Optional, see reference Figure 5 and Figure 6 The sedimentation tank 3 is equipped with a partition plate 37, which divides the internal space of the sedimentation tank 3 into a first cavity 38 and a second cavity 39. A support member 34 is provided at the opening 331 above the first cavity 38. The bottom of the partition plate 37 is provided with a notch 371, and the first cavity 38 and the second cavity 39 are connected through the notch 371.

[0040] When the operator needs to clean the impurities deposited at the bottom of the settling tank 3 using tools, the tools can be inserted into the settling tank 3 through the opening 332 above the second cavity 39. Since the support member 34 is only located at the opening 331 of the first cavity 38, it will not obstruct the operator. Furthermore, because the partition plate 37 has a notch 371 at its bottom, after inserting the tools into the second cavity 39, the operator can also insert the tools into the first cavity 38 through the notch 371, thereby thoroughly cleaning the bottom of the settling tank 3.

[0041] Optional, see reference Figure 5 and Figure 6At least one baffle plate 5 is provided on the side wall of the first cavity 38. The baffle plate 5 is connected to the sedimentation tank 3 by a spring hinge 51. The spring hinge 51 provides a force to keep the baffle plate 5 at a position higher than the opening 331. The baffle plate 5 can block liquid splashing in all directions and prevent liquid from splashing onto the ground and causing water accumulation. In addition, the baffle plate 5 is connected to the sedimentation tank 3 by the spring hinge 51. When the cleaning device stops working, the operator can fold the baffle plate 5 and lock it with a fastener or buckle (not shown in the figure) to store the baffle plate 5.

[0042] Optional, see reference Figure 1 The water pump 2 is a submersible pump, which is located at the bottom of the water tank 100. The drain outlet 31 of the sedimentation tank 3 is externally connected to a drain pipe 7, and the outlet of the drain pipe 7 is located above the water tank 100 or extends into the interior of the water tank 100.

[0043] Optional, see reference Figure 1 The water supply pipeline 1 includes a pipe body 13 and a tee pipe 14, and a water pump 2 is located between the pipe body 13 and the tee pipe 14. The tee pipe 14 is connected to the inlet of the water pump 2, the inlet of the pipe body 13 is connected to the outlet of the water pump 2, and the outlet of the pipe body 13 is the outlet end 12 of the water supply pipeline 1.

[0044] refer to Figure 7 The three-way pipe 14 is equipped with a first inlet 141, a second inlet 142, and an outlet 143. The outlet 143 is connected to the inlet of the water pump 2. Both the first inlet 141 and the second inlet 142 are located within the liquid in the water tank 100, and serve as the inlet ends 11 of the water supply pipe 1. The first inlet 141 is near the bottom of the water tank 100, and the second inlet 142 is near the surface of the liquid. In actual production, some of the soot and impurities in the liquid within the water tank 100 settle at the bottom, while some float on the surface, resulting in a significant amount of soot and impurities at both the bottom and surface of the water tank 100. This application, by setting up the three-way pipe 14, allows the first inlet 141 to draw water from the bottom of the water tank 100, and the second inlet 142 to draw water from the surface, thereby more comprehensively and effectively cleaning the liquid within the water tank 100.

[0045] Optional, see reference Figure 7A cylindrical body 6 is provided on the second water inlet 142. The cylindrical body 6 is arranged vertically, and its lower end is connected to the second water inlet 142. Multiple strip-shaped holes 61 are provided on the side wall of the cylindrical body 6, each extending vertically and spaced apart along the circumference of the cylindrical body 6. The surface of the liquid in the water tank 100 lies within the length of the strip-shaped holes 61, and the length of the strip-shaped holes 61 is greater than the change in liquid level in the water tank 100. Specifically, without the cylindrical body 6, when the liquid level in the water tank 100 rises, water and impurities on the liquid surface will not easily enter the second water inlet 142. When the liquid level in the water tank 100 decreases, the liquid level may drop below the second water inlet 142, preventing the second water inlet 142 from drawing water. This embodiment, by providing the cylinder 6 and the strip-shaped hole 61, ensures that even when the liquid level in the water tank 100 changes, water on the liquid surface can still enter the second inlet 142 through the strip-shaped hole 61, thereby preventing soot on the liquid surface from being unable to enter the second inlet 142 due to changes in the liquid level in the water tank 100. For example, the length of the strip-shaped hole 61 is 40-60 cm.

[0046] refer to Figure 1 and Figure 2 This application also provides a water tank with an automatic cleaning function, including a water tank 100 and any of the aforementioned cleaning devices.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
