Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a sedimentation tank effluent weir cleaning device and sedimentation tank. Background Technology

[0002] In urban wastewater treatment plants, sedimentation tanks are a crucial part of the wastewater treatment process. The clarified liquid above the sedimentation tank is discharged through the effluent weir at the top of the sedimentation tank. After long-term operation, algae, suspended solids, and other impurities in the clarified liquid can easily adhere to the inner wall of the effluent weir, which may affect the normal operation of the effluent weir and the quality of the effluent. In existing technologies, manual cleaning is mainly relied on periodic cleaning or the use of fixed mechanical scrapers. Manual cleaning is inefficient and labor-intensive. Fixed mechanical scrapers cannot adapt to the uneven inner wall of the effluent weir, which can easily create gaps and affect the cleaning effect.

[0003] Based on this, the applicant is considering designing a highly efficient and adaptable sedimentation tank effluent weir cleaning device and sedimentation tank. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a high-efficiency and highly adaptable sedimentation tank effluent weir cleaning device and sedimentation tank.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A sedimentation tank effluent weir cleaning device includes a fixed mounting base and a cleaning mechanism, wherein the cleaning mechanism includes a connecting part that is detachably connected to the mounting base;

[0007] The cleaning mechanism includes a mounting frame and a scraper for contacting the inner wall of the outlet weir. A fixed shaft is provided on the mounting frame, the scraper is hinged to the fixed shaft, and a torsion spring acting on the scraper is sleeved on the fixed shaft.

[0008] The working principle and advantages of the sedimentation tank effluent weir cleaning device in this technical solution are as follows:

[0009] In use, the mounting base is fixedly installed on the moving mechanism, and the cleaning mechanism is then connected to the mounting base via the connecting part, allowing the scraper on the cleaning mechanism to contact the inner wall of the outlet weir. The scraper is hinged to the mounting frame via a fixed shaft, allowing it to swing around the fixed shaft. Under the initial pressure of the torsion spring, the scraper can tightly contact the inner wall of the outlet weir. Driven by the moving mechanism, the scraper moves. When the scraper encounters protruding attachments or uneven areas on the outlet weir, it will push the scraper in the opposite direction, overcoming part of the torsion spring's force, forcing the scraper to rotate away from the inner wall of the outlet weir, thus avoiding damage to the scraper. After the scraper passes over the protrusion, the elastic potential energy stored in the torsion spring is immediately released, driving the scraper to swing back quickly and re-contact the inner wall of the outlet weir, ensuring the subsequent cleaning effect. When the scraper passes through a depression, the torsion spring will push the scraper to swing inward, maintaining contact with the outlet weir. It has strong adaptability, high cleaning efficiency, and good effect.

[0010] Furthermore, the cleaning mechanism includes a fixed rod fixedly connected to the connecting part and an adjusting rod hinged thereon, the mounting bracket is detachably connected to the adjusting rod, and an adjusting component for adjusting the angle of the adjusting rod is installed on the cleaning mechanism.

[0011] Furthermore, the adjustment assembly includes a first connecting rod, a second connecting rod, and a lifting screw threadedly connected to the connecting part; the bottom end of the lifting screw is rotatably connected to the first connecting rod, and the two ends of the second connecting rod are respectively hinged to the adjusting rod and the first connecting rod.

[0012] Furthermore, a rotating handwheel is detachably connected to the top of the lifting screw.

[0013] Furthermore, the mounting base includes a mounting plate and at least two clamping plates detachably connected thereto.

[0014] Furthermore, at least two mounting screws are fixedly connected to opposite sides of the mounting plate, the connecting part is a connecting plate, and at least two through holes are provided on both the connecting plate and the clamping plate for the mounting screws to pass through, and mounting nuts are threaded onto the mounting screws.

[0015] Furthermore, the mounting plate has multiple mounting slots.

[0032] Refer to together Figures 1 to 7 This embodiment provides a cleaning device for the effluent weir 120 of a sedimentation tank, which includes a fixedly installed mounting base 200 and a cleaning mechanism 300. The cleaning mechanism 300 includes a connecting part that is detachably connected to the mounting base 200.

[0033] The cleaning mechanism 300 includes a mounting frame 340 and a scraper 350 for contacting the inner wall of the outlet weir 120. A fixed shaft 341 is provided on the mounting frame 340, and the scraper 350 is hinged to the fixed shaft 341. A torsion spring 360 acting on the scraper 350 is sleeved on the fixed shaft 341.

[0034] In this embodiment, during use, the mounting base 200 is fixedly mounted on the moving mechanism, and the cleaning mechanism 300 is connected to the mounting base 200 through the connecting part, so that the scraper 350 on the cleaning mechanism 300 abuts against the inner wall of the outlet weir 120; the scraper 350 is hinged to the mounting frame 340 through the fixed shaft 341, so that the scraper 350 can swing around the fixed shaft 341 as the axis. Under the initial pressure of the torsion spring 360, the scraper 350 can abut tightly against the inner wall of the outlet weir 120. The scraper 350 moves under the drive of the moving mechanism. When the scraper 350 encounters the outlet weir 120... When encountering protruding attachments or uneven areas, the scraper 350 is pushed in the opposite direction, overcoming part of the force of the torsion spring 360, forcing the scraper 350 to rotate away from the inner wall of the outlet weir 120, thus avoiding damage to the scraper 350. After the scraper 350 passes over the protrusion, the elastic potential energy stored in the torsion spring 360 is immediately released, driving the scraper 350 to swing back quickly and re-engage with the inner wall of the outlet weir 120, ensuring the subsequent cleaning effect. When the scraper 350 passes through a depression, the torsion spring 360 pushes the scraper 350 to swing inward, maintaining contact with the outlet weir 120. It has strong adaptability, high cleaning efficiency, and good effect.

[0035] Preferably, such as Figures 1 to 5As shown, the cleaning mechanism 300 includes a fixed rod 320 fixedly connected to the connecting part and an adjusting rod 330 hinged to it. The mounting bracket 340 is detachably connected to the adjusting rod 330. An adjusting assembly for adjusting the angle of the adjusting rod 330 is installed on the cleaning mechanism 300. The inner contours of the effluent weir 120 of different sedimentation tanks are inconsistent. The inner wall of the effluent weir 120 is set vertically or inclined inward. By operating the adjusting assembly, the inclination angle of the adjusting rod 330 relative to the fixed rod 320 is changed to adapt to the inner contour of the effluent weir 120, further improving the applicability of the device. When cleaning is not required, the scraper 350 of the cleaning mechanism 300 can be adjusted so that it does not contact the inner wall of the effluent weir 120.

[0036] Preferably, such as Figures 1 to 5 As shown, the adjustment assembly includes a first connecting rod 381, a second connecting rod 382, ​​and a lifting screw 380 threadedly connected to the connecting part. The bottom end of the lifting screw 380 is rotatably connected to the first connecting rod 381, and both ends of the second connecting rod 382 are hinged to the adjusting rod 330 and the first connecting rod 381, respectively. When the operator rotates the lifting screw 380, since the lifting screw 380 is threadedly connected to the connecting part, the lifting screw 380 can move up and down on the connecting part. The bottom end of the lifting screw 380 is rotatably connected to the first connecting rod 381. When the lifting screw 380 moves up and down, it will drive the first connecting rod 381 to move up and down together. When the first connecting rod 381 moves up and down, it will be transmitted to the adjusting rod 330 through the second connecting rod 382, ​​which is hinged to it, thereby adjusting the tilt angle of the cleaning mechanism 300 of the adjusting rod 330. Specifically, a threaded tube 370 is fixedly installed on the connecting part, and the lifting screw 380 is threadedly connected to the threaded tube 370.

[0037] Preferably, such as Figures 1 to 5 As shown, a rotating handwheel 383 is detachably connected to the top of the lifting screw 380; the operator can drive the lifting screw 380 to lift or lower by rotating the rotating handwheel 383 clockwise or counterclockwise, which is convenient and quick.

[0038] Preferably, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 7 As shown, the mounting base 200 includes a mounting plate 210 and at least two clamping plates 220 detachably connected thereto. During installation, the mounting base 200 is placed on the moving mechanism, and the two clamping plates 220 are clamped onto the moving mechanism by adjustment, which enables quick and stable installation. Specifically, the clamping plate 220 is an L-shaped plate, and a locking rod 221 is threadedly connected to the clamping plate 220. The locking rod 221 is rotated to assist in locking the installation.

[0039] Preferably, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 as well as Figure 7 As shown, at least two mounting screws 212 are fixedly connected to opposite sides of the mounting plate 210. The connecting part is a connecting plate 310. Both the connecting plate 310 and the clamping plate 220 have at least two through holes for the mounting screws 212 to pass through. The mounting screws 212 are threaded with mounting nuts 230. The mounting screws 212 can pass through the through holes in the connecting plate 310 and the clamping plate 220. The clamping plate 220 and the connecting plate 310 are then fixedly connected to the mounting plate 210 by tightening the mounting nuts 230. Specifically, a washer 240 can be provided between the clamping plate 220 and the connecting plate 310 to prevent mutual interference.

[0040] Preferably, such as Figure 6 as well as Figure 7 As shown, the mounting plate 210 has multiple mounting slots 211; the mounting slots 211 can form an installation space, and screw holes corresponding to the mounting slots 211 can be made on the moving mechanism, so that the mounting plate 210 and the moving mechanism can be fixedly connected together by bolts, thus increasing the installation methods.

[0041] Preferably, such as Figure 1 and Figure 2 As shown, at least one cleaning mechanism 300 is installed at each of the opposite ends of the mounting base 200; the two cleaning mechanisms 300 can respectively correspond to the opposite two side walls of the outlet weir 120, and can simultaneously clean the two inner walls of the outlet weir 120.

[0042] Preferably, such as Figures 1 to 5 As shown, a flexible strip 351 is installed on the side of the scraper 350 that contacts the outlet weir 120. When the scraper 350 is pressed against the weir wall under the action of the torsion spring 360, the flexible strip 351 undergoes elastic deformation and comes into closer contact with the inner wall of the outlet weir 120, further improving the cleaning effect.

[0043] Specifically, such as Figures 1 to 5 As shown, the torsion spring 360 can be a double torsion spring 360 in the prior art. The middle section of the double torsion spring 360 is in contact with or fixedly connected to the scraper 350, and the two ends of the double torsion spring 360 are in contact with or fixedly connected to the mounting bracket 340.

[0044] like Figure 8 As shown, the sedimentation tank includes a sedimentation tank body 100 and the aforementioned sedimentation tank effluent weir 120 cleaning device; the sedimentation tank body 100 includes a peripheral drive sludge scraper 110, the peripheral drive sludge scraper 110 includes a working bridge 111, and the mounting base 200 of the sedimentation tank effluent weir 120 cleaning device is fixedly installed on the working bridge 111.

[0045] In the prior art, the sedimentation tank body 100 is usually equipped with a peripheral drive sludge scraper 110 that can rotate and move. This is a moving mechanism that conforms to the moving trajectory of the cleaning mechanism 300. The mounting base 200 is fixedly installed on the working bridge 111 of the peripheral drive sludge scraper 110. By using the rotation of the peripheral drive sludge scraper 110 during its circular operation, the cleaning mechanism 300 can be driven to rotate, cleaning the effluent weir 120 on the annular sedimentation tank body 100. No additional power source is required, which is energy-saving and environmentally friendly. During installation, the mounting plate 210 of the mounting base 200 is placed above the working bridge 111, and the clamping plate 220 is clamped on the two sides and bottom of the working bridge 111, so that the mounting base 200 can be stably installed on the working bridge 111, thereby allowing the cleaning mechanism 300 to rotate together with the working bridge 111.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
