Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a spray cleaning device for a secondary sedimentation tank. Background Technology

[0002] Secondary sedimentation tanks, also known as settling tanks, are an important component of activated sludge systems. Their primary function is to separate sludge, clarify and concentrate the mixed liquor, and return the activated sludge. Their performance directly impacts the effluent quality and the concentration of returned sludge. Large and medium-sized wastewater treatment plants often use circular radial flow sedimentation tanks with mechanical sludge suction; medium-sized plants may use multi-hopper horizontal flow sedimentation tanks; and small plants typically use vertical flow tanks. Secondary sedimentation tanks require cleaning after prolonged use to prevent residual substances from affecting the sedimentation of subsequent batches. However, current cleaning equipment still has the following drawbacks in practical use:

[0003] Firstly, the cleaning operation of secondary sedimentation tanks mainly involves cleaning the bottom and walls of the tank. However, the size of conventional secondary sedimentation tanks is relatively large, and cleaning is mostly carried out by splashing cleaning agents and rinsing. This method is irregular, has low cleaning efficiency, and requires a lot of time and effort, especially the cleaning effect on the tank walls is far from sufficient.

[0004] Secondly, for cleaning the large area of ​​the pool bottom, a larger and more uniform spray area is needed. In contrast, cleaning the pool walls only requires water to be sprayed from one side. Therefore, a cleaning device that can meet both functions is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a secondary sedimentation tank spray cleaning device. By setting up a base plate, vertical plate, ring pipe, cleaning pipe, lifting motor, and rotating motor, it solves the problems of lacking a more efficient method for cleaning the walls of secondary sedimentation tanks and the need for the cleaning device to add a function for large-area uniform cleaning of the tank bottom on the basis of satisfying the cleaning of the tank walls.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a secondary sedimentation tank spray cleaning device, comprising a vertical plate, a base plate, a rotating shaft, an annular pipe, and a cleaning pipe. A base plate is movably mounted on one side of the vertical plate. A rotary motor is fixed at the center of the upper end of the base plate, and a central rotating shell is fixed through the base plate outside the rotary motor. The output shaft of the rotary motor passes downward through the base plate and is fixed to the rotating shaft. A first-generation connecting rod arranged in a circular array is fixed on the lower outer circumference of the rotating shaft, and the outer ends of all first-generation connecting rods are jointly fixed to the annular pipe. A first-generation nozzle arranged in a circular array and pointing downwards is fixed through the outer curved surface of the annular pipe. A second-generation cleaning pipe arranged in a circular array is also provided below the annular pipe, and a second-generation nozzle arranged at equal intervals and pointing downwards is fixed through the outer circumference of the cleaning pipe. A second-generation connecting rod is also fixed on the outer circumference of the cleaning pipe, and the end of the second-generation connecting rod away from the cleaning pipe is fixed to the outer circumference of the rotating shaft.

[0008] Furthermore, a support platform is fixed to the lower part of the vertical plate away from the base plate, and a storage tank is fixed inside the support platform. The top of the storage tank extends out of the top surface of the support platform and is connected to a water supply pipe. The end of the water supply pipe away from the storage tank is connected to the upper end of the transfer shell and fixed.

[0009] Furthermore, the vertical plate has three equidistantly distributed lifting slots on the side near the base plate, and a screw is rotatably connected in the lifting slot at the center, while sliding rods are fixed in the lifting slots on both sides. A lifting motor is fixed at the top of the vertical plate, and the output shaft of the lifting motor is fixedly connected to the top of the screw.

[0010] Furthermore, the substrate has three equally spaced sliders fixed on the side near the vertical plate, and all three sliders slide within the lifting groove. The slider at the center is threaded to the outside of the screw rod, and the sliders on both sides are sleeved on the outside of the sliding rod.

[0011] Furthermore, a cleaning agent bottle is fixed on the side of the substrate adjacent to the vertical plate, and a branch pipe is fixed through the upper end of the cleaning agent bottle. The end of the branch pipe away from the cleaning agent bottle is fixed through the periphery of the ring pipe.

[0012] Furthermore, a conveying pipe is also fixedly connected to the outer periphery of the cleaning pipe, the top end of the conveying pipe is fixedly connected to the bottom of the transfer shell, and a valve is also fixed on the conveying pipe.

[0013] This utility model has the following beneficial effects:

[0014] This utility model solves the problem of lacking a more efficient method for cleaning the walls of secondary sedimentation tanks by setting up a base plate, vertical plate, ring pipe, cleaning pipe, and lifting motor; when cleaning the tank walls, such as Figure 2As shown in the diagram, the support platform is placed on the ground outside the edge of the secondary sedimentation tank. The lifting motor operates, driving the screw to rotate, causing the slider and base plate to descend. This allows the ring pipe and cleaning pipe to descend along the tank wall. By controlling the forward and reverse rotation of the lifting motor, the lifting and lowering of the ring pipe and cleaning pipe can be controlled. Simultaneously, the cleaning agent in the cleaning agent bottle is delivered to the ring pipe and sprayed onto the tank wall through nozzle one. The cleaning water is then delivered to the transfer tank through the storage tank, and then delivered to the cleaning pipe through the delivery pipe and sprayed onto the tank wall through nozzle two for cleaning. Only the valve on the delivery pipe closest to the tank wall is open. In conjunction with the lifting and lowering of the base plate, a reciprocating lifting and cleaning operation is achieved. Combined with the support platform moving around the edge of the secondary sedimentation tank, a fast and efficient cleaning operation is achieved.

[0015] This invention solves the problem of needing cleaning equipment to perform large-area, uniform cleaning of the pool bottom in addition to cleaning the pool walls, by incorporating a ring pipe, a cleaning pipe, and a rotating motor. When cleaning the pool bottom, it is... Figure 1 As shown, the device is placed at the bottom of the pool. Similarly, the cleaning agent in the cleaning agent bottle is delivered to the ring pipe and sprayed onto the bottom of the pool through nozzle one. The storage tank delivers the cleaning water to the transfer shell, and then delivers it to the cleaning pipe through the delivery pipe, where it is sprayed onto the bottom of the pool through nozzle two. At the same time, the rotary motor drives the rotating shaft to reciprocate at a certain angle (each rotation does not exceed 60 degrees), which will drive nozzle one and nozzle two to perform a periodic reciprocating spray cleaning effect on the bottom of the pool. Then, the device can be moved to achieve a large-area and uniform spray cleaning effect. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 As shown, this utility model is a secondary sedimentation tank spray cleaning device, including a vertical plate 1, a base plate 3, a rotating shaft 4, an annular pipe 5 and a cleaning pipe 6. The base plate 3 is movably arranged on one side of the vertical plate 1. A rotary motor 401 is fixed at the upper center of the base plate 3. A central rotating shell 301 is fixed through the base plate 3 outside the rotary motor 401. The output shaft of the rotary motor 401 passes through the base plate 3 downward and is fixed to the rotating shaft 4. A connecting rod 501 arranged in a ring array is fixed on the lower outer circumferential surface of the rotating shaft 4. The outer ends of all the connecting rods 501 are fixed to the annular pipe 5. An inclined downward nozzle 502 is fixed through the outer curved surface of the annular pipe 5 in a ring array.

[0026] Below the ring pipe 5, there is also a cleaning pipe 6 arranged in a ring array, and nozzles 602 that are evenly distributed and inclined downwards are fixed through the outer circumferential surface of the cleaning pipe 6; a connecting rod 601 is also fixed on the outer circumferential surface of the cleaning pipe 6, and the end of the connecting rod 601 away from the cleaning pipe 6 is fixed to the outer circumference of the rotating shaft 4.

[0027] The vertical plate 1 serves as an important connecting carrier, with the base plate 3 movably mounted on its side. The base plate 3 is equipped with a transfer shell 301 for transferring the injection of cleaning water. In conjunction with the rotary motor 401, it can drive the rotating shaft 4 to perform reciprocating rotation, thereby driving the annular pipe 5 connected to the rotating shaft 4 via the first connecting rod 501 to rotate. At the same time, it also drives the cleaning pipe 6 connected via the second connecting rod 601 to rotate reciprocally. At this time, the cleaning liquid sprayed from the first nozzle 502 and the cleaning water sprayed from the second nozzle 602 will form a scattered and uniform spray cleaning effect.

[0028] A support platform 2 is fixed to the lower part of the side of the vertical plate 1 away from the base plate 3, and a storage tank 201 is fixed inside the support platform 2. The top of the storage tank 201 extends out of the top surface of the support platform 2 and is connected to a water pipe 202. The end of the water pipe 202 away from the storage tank 201 is connected to the upper end of the transfer shell 301 and fixed.

[0029] The support platform 2 is used to install the storage tank 201, and the bottom of the support platform 2 is equipped with rollers for rolling movement, which is convenient for moving. The storage tank 201 is equipped with a corresponding pump, which outputs cleaning water through the water supply pipe 202 and injects it into the transfer shell 301.

[0030] Three equidistant lifting slots 102 are provided on the side of the vertical plate 1 near the base plate 3. A screw 103 is rotatably connected in the lifting slot 102 located in the center. Slide rods 104 are fixed in the lifting slots 102 located on both sides. A lifting motor 101 is fixed on the top of the vertical plate 1, and the output shaft of the lifting motor 101 is fixedly connected to the top of the screw 103.

[0031] On the side of the substrate 3 near the vertical plate 1, there are three equally spaced sliders 302, and all three sliders 302 slide in the lifting groove 102. The slider 302 located in the center is threaded to the outside of the screw 103 and forms a threaded connection with the screw 103. The sliders 302 on both sides are sleeved on the outside of the slide rod 104.

[0032] The lifting motor 101 drives the screw 103 to rotate, and the slider 302 outside the screw 103 will rise and fall in the lifting groove 102 (by controlling the forward and reverse rotation of the lifting motor 101 to change the rise or fall). The other two sliders 302 assist in limiting the rise and fall outside the slide bar 104 to ensure stability and avoid excessive force on a single slider 302.

[0033] A cleaning agent bottle 7 is fixed on the side of the substrate 3 adjacent to the vertical plate 1, and a branch pipe 701 is fixed through the upper end of the cleaning agent bottle 7. The end of the branch pipe 701 away from the cleaning agent bottle 7 is fixed through the periphery of the ring pipe 5. The cleaning agent bottle 7 contains cleaning agent, which is input into the ring pipe 5 through the branch pipe 701 and then sprayed out from the nozzle 502.

[0034] A conveying pipe 603 is also fixedly connected to the outer periphery of the cleaning pipe 6. The top end of the conveying pipe 603 is fixedly connected to the bottom of the transfer shell 301, and a valve 604 is also fixed on the conveying pipe 603. The conveying pipe 603 is used to convey the cleaning water in the transfer shell 301 to the cleaning pipe 6. By controlling the corresponding valve 604, the cleaning water can be selected to be conveyed to the corresponding cleaning pipe 6.

[0035] The specific working principle of this utility model is as follows: First, when cleaning the pool wall, if... Figure 2As shown in the diagram, the support platform 2 is placed on the ground outside the edge of the secondary sedimentation tank. The lifting motor 101 operates, driving the screw 103 to rotate, causing the slider 302 and the base plate 3 to descend. This causes the ring pipe 5 and the cleaning pipe 6 to descend along the tank wall. At this time, the cleaning agent in the cleaning agent bottle 7 is delivered to the ring pipe 5 and sprayed onto the tank wall through nozzle 502. The cleaning water is then delivered to the transfer shell 301 through the storage tank 201 and then delivered to the cleaning pipe 6 through the delivery pipe 603, where it is sprayed onto the tank wall through nozzle 602 for cleaning. At this time, only the valve 604 on the delivery pipe 603 near the tank wall is open, while the remaining valves 604 remain closed. Subsequently, in conjunction with the support platform 2 moving around the edge of the secondary sedimentation tank and the cyclic lifting and lowering operation of the base plate 3, the tank wall is cleaned. In this state, the rotary motor 401 does not operate.

[0036] When cleaning the bottom of the pool, it should be handled as follows: Figure 1 As shown, the cleaning agent is placed at the bottom of the pool. Similarly, the cleaning agent in the cleaning agent bottle 7 is delivered to the ring pipe 5 and sprayed onto the bottom of the pool through nozzle 502. The storage tank 201 delivers the cleaning water to the transfer shell 301, and then delivers it to the cleaning pipe 6 through the delivery pipe 603, from which it is sprayed onto the bottom of the pool through nozzle 602. At the same time, the rotary motor 401 drives the rotating shaft 4 to reciprocate at a certain angle, which will drive nozzle 502 and nozzle 602 to perform a periodic reciprocating spray cleaning effect on the bottom of the pool. In this state, the lifting motor 101 does not work.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
