Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to the design of a high-efficiency sedimentation tank overflow trough cleaning device. Background Technology

[0002] High-efficiency sedimentation tanks are a wastewater treatment process that utilizes physical / chemical treatment and a special flocculation and sedimentation system to achieve rapid sedimentation. This process integrates rapid mixing, flocculation reaction, and sedimentation separation. Its core principle is to utilize the sludge accumulated in the tank, which, through external recirculation, comes into contact with and adsorbs particles in the water, accelerating particle flocculation and promoting the rapid separation of impurities. Combined with inclined tube or inclined plate packing, the sedimentation process is further accelerated, achieving highly efficient solid-liquid separation.

[0003] When high-efficiency sedimentation tanks are in use, they are often exposed to direct sunlight, and under conditions of sufficient dissolved oxygen in the circulating water, suitable temperature, and eutrophication, the inner and outer walls of their overflow channels are prone to the growth of moss and algae. If not cleaned promptly, this will lead to water quality deterioration, affecting the sedimentation effect of the high-efficiency sedimentation tank and causing further water quality degradation. Therefore, cleaning the overflow channel is extremely important. Current cleaning methods mainly rely on manual washing. However, because the overflow channel of the high-efficiency sedimentation tank is located below the water level, with a significant drop, manual cleaning is ineffective, severely impacting the sedimentation effect. To address these problems and the shortcomings of existing technologies, we propose a cleaning device for the overflow channel of high-efficiency sedimentation tanks. Summary of the Invention

The first sleeve is movably mounted on the first drive shaft, and the second sleeve is movably mounted on the inner wall cleaning assembly.

[0010] Furthermore, the inner wall cleaning assembly includes a swinging rotating rod, which is independently installed inside the second sleeve. A second power input transmission component that is in transmission cooperation with the first power output transmission component is fitted on the top of the swinging rotating rod, and an inner wall cleaning roller brush is threadedly connected to the bottom of the swinging rotating rod.

[0011] A first threaded sleeve is provided on the swinging rotating rod, and a first limiting ring is formed on the swinging rotating rod below the first threaded sleeve.

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figures 1-9 As shown, a high-efficiency sedimentation tank overflow trough cleaning device 100 includes a control mechanism (not shown), a traveling mechanism 10 for reciprocating along a rectangular tube on the overflow trough 200, a plurality of cleaning mechanisms 20 mounted on the traveling mechanism 10 for cleaning the inner and outer side walls of the overflow trough 200, and a power supply module (not shown) for supplying power to the control mechanism, the traveling mechanism 10, and the cleaning mechanisms 20.

[0035] The control mechanism can set parameters such as the moving speed of the walking mechanism 10 and the cleaning speed of the cleaning mechanism 20 during the cleaning process, and provide corresponding control over the cleaning process. The walking mechanism 10 drives the cleaning equipment 100 to reciprocate along the overflow trough 200, enabling the cleaning mechanism 20 to automatically clean the inner and outer walls of the overflow trough 200. To improve cleaning efficiency, it is preferable that the walking mechanism 10 moves along the length of the overflow trough 200, allowing the cleaning mechanism 20 to simultaneously clean the inner and outer walls of both sides of the overflow trough 200.

[0036] In this embodiment, the walking mechanism 10 includes a horizontally arranged base plate 11, a second drive assembly 12 fixed to the center of the base plate 11, and four sets of wheeled moving assemblies 13 mounted and fixed on the base plate 11 along the moving direction of the walking mechanism 10. The second drive assembly 12 and each set of wheeled moving assemblies 13 are respectively connected by a second transmission assembly 14. Specifically:

[0037] The second drive assembly 12 includes a second drive motor 121 with a reduction mechanism and a second drive member 122 mounted on the output shaft of the second drive motor 121. The output shaft of the second drive motor 121 outputs power and transmits it to the second drive member 122 via the reduction mechanism.

[0038] The second transmission assembly 14 includes a plurality of second mounting seats 141 and a plurality of third mounting seats 142 fixed on the base plate 11. A second transmission shaft 143 is rotatably mounted on the second mounting seat 141. A fourth power input transmission component 145, which is in transmission cooperation with the second drive component 122, is mounted on one end of the second transmission shaft 143. A third power output transmission component 146 is mounted on the other end of the second transmission shaft 143. A third transmission shaft 144 is rotatably mounted on the third mounting seat 142. A fifth power input transmission component 147, which is in transmission cooperation with the third power output transmission component 146, is mounted on one end of the third transmission shaft 144. A fourth power output transmission component 148, which is in transmission connection with the wheeled moving assembly 13, is mounted on the other end of the third transmission shaft 144. The centerline of the third transmission shaft 144 is perpendicular to the centerline of the second transmission shaft 143.

[0039] Based on the above structure, the power output by the second drive member 122 is transmitted to the second drive shaft 143 via the fourth power input transmission member 145, and then to the fifth power input transmission member 147 via the third power output transmission member 146 fixed on the second drive shaft 143. After that, it is output to the wheeled moving assembly 13 by the third drive shaft 144 and the fourth power output transmission member 148, thereby driving the wheeled moving assembly 13 to rotate and realize the walking mechanism 10 to move.

[0040] In this example, the second drive component 122, the fourth power input transmission component 145, the third power output transmission component 146, the fifth power input transmission component 147, and the fourth power output transmission component 148 all use bevel gears, thus enabling multi-stage transmission and reversal. The second drive shaft 143 and the third drive shaft 144 synchronously drive the four sets of wheeled moving components 13 to rotate in both directions, thereby allowing the equipment to reciprocate on the rectangular tube of the overflow trough 200.

[0041] In this embodiment, lifting components 15 are provided on any two opposite sides of the base plate 11, so as to facilitate the placement or lifting of the cleaning equipment 100 from the sedimentation tank before and after cleaning; the second drive assembly 12 and the second transmission assembly 14 are both provided on the upper surface of the base plate 11, and a housing 16 is provided on the base plate 11 covering the first drive assembly 21, the second drive assembly 12, and the second transmission assembly 14. A protective cover 17 is also provided on the base plate 11 above the wheeled moving assembly 13. The housing 16 and the protective cover 17 can effectively protect the transmission mechanism and prevent factors such as rust from affecting the life of the equipment.

[0042] In this example, the cleaning mechanism 20 includes a first drive assembly 21, a first transmission assembly 22, an inner wall cleaning assembly 23, and an outer wall cleaning assembly 24. The first drive assembly 21 is fixed to the walking mechanism 10. The power output end of the first drive assembly 21 is connected to the inner wall cleaning assembly 23 and the outer wall cleaning assembly 24 through the first transmission assembly 22, so as to drive the inner wall cleaning assembly 23 and the outer wall cleaning assembly 24 to simultaneously clean the inner and outer side walls of the overflow tank 200. Specifically:

[0043] The first drive assembly 21 includes a first drive motor 211 with a reducer and a first drive member 212. The first drive motor 211 is fixed on the walking mechanism 10. The first drive member 212 is installed on the output shaft of the first drive motor 211 and is connected to the first transmission assembly 22 for transmission, thereby driving the inner wall cleaning assembly 23 and the outer wall cleaning assembly 24 to clean the inner and outer side walls of the overflow tank 200 simultaneously.

[0044] The first mounting base 221 includes a mounting plate 2211 fixedly connected to the lower surface of the base plate 11 in the walking mechanism 10. Two limiting sleeves 2212 containing bearings and a mounting sleeve 2213 containing bearings are fixed on the mounting plate 2211. The first drive shaft 222 passes through the limiting sleeve 2212. The outer wall cleaning assembly 24 is fixed in the mounting sleeve 2213. The center line of the limiting sleeve 2212 is perpendicular to the center line of the mounting sleeve 2213. The mounting sleeve 2213 is located outside the vertical projection of the base plate 11, so that there is a gap between the outer wall cleaning assembly 24 and the base plate 11, thereby ensuring that a gap that matches the overflow groove 200 is formed between the inner wall cleaning assembly 23 and the outer wall cleaning assembly 24.

[0045] The first transmission assembly 22 includes a first mounting base 221, a first transmission shaft 222, a first power input transmission component 223, a first power output transmission component 224, and a second power output transmission component 225. The first transmission shaft 222 is fixed to the lower surface of the base plate 11 in the walking mechanism 10 through the first mounting base 221. The first power input transmission component 223, the first power output transmission component 224, and the second power output transmission component 225 are all mounted on the first transmission shaft 222. The first power input transmission component 223 is in transmission cooperation with the first driving component 212, the first power output transmission component 224 is in transmission connection with the inner wall cleaning assembly 23, and the second power output transmission component 225 is in transmission connection with the outer wall cleaning assembly 24.

[0046] Based on the above structure, the first drive motor 211 with a reducer outputs cleaning power through the first drive member 212. The cleaning power is transmitted to the first drive shaft 222 via the first power input transmission member 223, and then to the inner wall cleaning assembly 23 via the first power output transmission member 224 and to the outer wall cleaning assembly 24 via the second power output transmission member 225. This provides power to the inner wall cleaning assembly 23 and the outer wall cleaning assembly 24 to clean the inner and outer walls of the overflow tank 200.

[0047] In this example, the first power input transmission component 223, the first power output transmission component 224, and the second power output transmission component 225 all use bevel gears, which cooperate with the first transmission shaft 222 to form a multi-stage transmission structure, realize the reversal of driving force, and thus drive the inner wall cleaning component 23 and the outer wall cleaning component 24 to rotate and clean.

[0048] In the specific implementation process, since there is a horizontal connecting rod on the inner wall of the overflow tank 200, it will obstruct the path of the inner wall cleaning component 23. Therefore, the inner wall cleaning component 23 is set as a swingable rotating mechanism plus a roller brush. During the cleaning process, when the inner wall cleaning component 23 touches the horizontal connecting rod, it can swing freely and automatically cross the horizontal connecting rod to achieve unobstructed reciprocating motion cleaning. Specifically: The inner wall cleaning assembly 23 is connected to the first drive shaft 222 via a movable connector 25. The movable connector 25 includes a first sleeve 251 and a second sleeve 252, which are connected by an L-shaped connecting block 253. After connection, the center line of the first sleeve 251 is perpendicular to the center line of the second sleeve 252, thereby converting the force output by the horizontal first drive shaft 222 to the vertical direction. The first sleeve 251 is movably mounted on the first drive shaft 222 so that the inner wall cleaning assembly 23 can swing around the first drive shaft 222 when subjected to external force. The second sleeve 252 is movably mounted on the inner wall cleaning assembly 23 so that the inner wall cleaning assembly 23 can rotate and clean moss when driven by the first drive assembly 22.

[0049] Based on the above structure, when the inner wall cleaning component 23 touches the transverse connecting rod during the cleaning process, the inner wall cleaning component 23 can swing around the first drive shaft 222, thereby crossing the transverse connecting rod.

[0050] In this example, the inner wall cleaning assembly 23 includes a swinging rotating rod 231, which is independently inserted into the second sleeve 252. A second power input transmission component 232 that is in transmission cooperation with the first power output transmission component 224 is fitted on the top of the swinging rotating rod 231. An inner wall cleaning roller brush 233 is threadedly connected to the bottom of the swinging rotating rod 231.

[0051] A first threaded sleeve 234 is provided on the swinging rotating rod 231, and a first limiting ring 235 is formed on the swinging rotating rod 231 below the first threaded sleeve 234. The upper end of the inner wall cleaning roller brush 233 is threadedly connected to the first threaded sleeve 234, and the upper end face of the inner wall cleaning roller brush 233 abuts against the lower surface of the first limiting ring 235.

[0052] In this example, the outer wall cleaning assembly 24 includes a fixed rotating rod 241, the top of which is rotatably mounted in the mounting sleeve 2213. A third power input transmission component 242, which is in transmission cooperation with the second power output transmission component 225, is fitted on the upper part of the fixed rotating rod 241. An outer wall cleaning roller brush 243 is threadedly connected to the bottom of the fixed rotating rod 241.

[0053] A second threaded sleeve 244 is provided on the fixed rotating rod 241, and a second limiting ring 245 is formed on the fixed rotating rod 241 below the second threaded sleeve 244. The upper end of the outer wall cleaning roller brush 243 is threadedly connected to the second threaded sleeve 244, and the upper end face of the outer wall cleaning roller brush 243 abuts against the lower surface of the second limiting ring 245.

[0054] Based on the above design, with the inner wall cleaning component 23 and the outer wall cleaning component 24 having cleaning functions, a detachable screw sleeve connection for the roller brush is realized, which makes it easy to replace the roller brush and facilitates later maintenance.

[0055] Working principle:

[0056] First, the cleaning device 100 of the present invention is arranged according to... Figure 10 The cleaning device 100 is placed on the rectangular tube of the overflow tank 200 as shown. Then, the control mechanism issues control commands according to the set cleaning parameters. After that, the walking mechanism 10 executes corresponding actions according to the control commands. At this time, the second drive component 12 outputs power and transmits it to the wheeled moving component 13 through the second transmission component 14, thereby driving the cleaning device 100 to move back and forth along the overflow tank 200. Finally, the cleaning mechanism 20 executes corresponding actions according to the control commands. The first drive component 21 outputs power and transmits it to the inner wall cleaning component 23 and the outer wall cleaning component 24 through the first transmission component 22, so as to drive the inner wall cleaning component 23 and the outer wall cleaning component 24 to simultaneously clean the inner and outer walls of the overflow tank 200, realizing the synchronous automatic cleaning of the inner and outer walls of the overflow tank on both sides of the high-efficiency sedimentation tank, effectively improving the cleaning efficiency of the overflow tank, and is safer than traditional technology.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
