Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a self-cleaning wastewater treatment device. Background Technology

[0002] Wastewater refers to water that has become polluted during use, contains harmful substances, or has undergone changes in quality, rendering it unsuitable for its original purpose or unable to be directly discharged into the natural environment. It originates from various domestic and production activities, such as industrial production, agricultural irrigation, urban life, and medical activities. If wastewater is discharged directly into the environment without treatment, it will pollute water bodies, soil, and air, thereby threatening human health and ecological balance.

[0003] In wastewater treatment, the first step is to use filters to remove suspended solids, silt, and other impurities from the wastewater. However, after prolonged use, the filters become clogged with various impurities, causing a sharp decline in filtration efficiency. As a result, workers need to clean the filters constantly, which is not only labor-intensive but also inefficient, thus reducing the overall wastewater treatment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning wastewater treatment device that effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A self-cleaning wastewater treatment device includes a base. Two water filter tanks and two wastewater tanks are respectively mounted on the upper surface of the base, with the tanks staggered. A turntable is mounted on the top of each of the water filter tanks and wastewater tanks via a first rotating mechanism. The turntable has four slots on its surface, each corresponding to one of the water filter tanks and wastewater tanks. A mounting frame is rotatably mounted inside each slot via a rotating shaft. Filter screens are installed inside the mounting frames. A flipping mechanism capable of simultaneously driving the rotation of all four filter screens is located in the center of the turntable. Water injection pipes are installed above each of the water filter tanks, and a flushing mechanism is installed above each of the wastewater tanks.

[0007] Furthermore, the first rotating mechanism includes a fixed plate installed on the outside of the two water filter tanks and the two sewage tanks. A rotating seat is rotatably mounted on the upper surface of the fixed plate, and a turntable is mounted on the top of the rotating seat. A first driven gear is mounted on the outer surface of the rotating seat, and a first servo motor is mounted on the outer surface of the fixed plate. A first drive gear is mounted on the end of the output shaft of the first servo motor, and the first drive gear meshes with the first driven gear.

[0008] Furthermore, the flipping mechanism includes a mounting groove on the surface of the turntable, the ends of four rotating shafts all passing through the mounting groove and equipped with driven bevel gears, a U-shaped frame is mounted on the top of the turntable, a second servo motor is mounted on the upper surface of the U-shaped frame, and a drive bevel gear is mounted on the end of the output shaft of the second servo motor, which simultaneously meshes with the four driven bevel gears.

[0009] Furthermore, the flushing mechanism includes a cantilever mounted above the wastewater tank. An inlet pipe is rotatably installed through the cantilever. A horizontal pipe is installed at the bottom of the inlet pipe, and multiple nozzles are arranged along its length on the lower surface of the horizontal pipe. A rotary joint is installed at the top of the inlet pipe. A water pump is installed on the upper surface of the base. The suction end of the water pump is connected to the filter tank, and the output end of the water pump is connected to a flexible hose, the end of which is connected to the rotary joint. A second rotating mechanism capable of driving the inlet pipe to rotate is provided on the outer surface of the cantilever.

[0010] Furthermore, the second rotating mechanism includes a third servo motor mounted on the end of the cantilever, a second drive gear mounted on the end of the output shaft of the third servo motor, a second driven gear mounted on the outer surface of the water inlet pipe, and the second driven gear meshing with the second drive gear.

[0011] Furthermore, an electric push rod is installed on the upper surface of the base, and the end of the telescopic end of the electric push rod is connected to the cantilever.

[0012] Furthermore, the upper and lower sides of the mounting frame are equipped with side panels.

[0013] Furthermore, the outer surface of the water filter tank is connected to an outlet pipe, and the outer surface of the wastewater tank is connected to a wastewater pipe. The height of the outlet pipe is higher than the height of the water pump suction end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model uses a first rotating mechanism to drive a turntable to rotate at a certain angle, moving the filter screen to be cleaned to the top of the sewage tank. Then, a flipping mechanism drives the filter screen to rotate 180 degrees, so that the side with the adhering impurities faces down. Next, a second rotating mechanism drives a rinsing mechanism to rotate, rinsing the filter screen from top to bottom. Thus, the impurities adhering to the lower surface of the filter screen can be washed away and fall into the sewage tank, achieving the purpose of self-cleaning. This not only reduces the labor intensity of workers but also has a good cleaning effect, reducing the interruption time of wastewater treatment, thus significantly improving the wastewater treatment efficiency.

[0016] 2. By raising the water outlet pipe higher than the water pump suction end, this utility model allows the water tank to maintain a certain water level for the rinsing mechanism, eliminating the need for additional water resources and reducing costs. Attached Figure Description

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-6 This utility model provides a self-cleaning wastewater treatment device, including a base 100. Two water filter tanks 101 and two wastewater tanks 102 are respectively mounted on the upper surface of the base 100, and the two water filter tanks 101 and two wastewater tanks 102 are staggered. A turntable 103 is mounted on the top of the two water filter tanks 101 and two wastewater tanks 102 via a first rotating mechanism 200. Four through slots 104 are formed on the surface of the turntable 103, and each of the four through slots 104 corresponds one-to-one with one of the two water filter tanks 101 and two wastewater tanks 102. A mounting frame 106 is rotatably mounted inside the through slots 104 via a rotating shaft 105. Filter screens 107 are disposed inside the mounting frame 106. A flipping mechanism 300 capable of simultaneously driving the rotation of all four filter screens 107 is disposed at the center of the turntable 103. A water injection pipe 108 is disposed above each of the two water filter tanks 101, and a flushing mechanism 400 is disposed above each of the two wastewater tanks 102.

[0028] In use, the wastewater to be treated flows from the water inlet pipe 108 to the filter screen 107. After the filter screen 107 filters out the impurities, the wastewater enters the water filter tank 101. When there are many impurities adhering to the upper surface of the filter screen 107, affecting the flow of water, the flow of wastewater in the water inlet pipe 108 can be stopped first. Then, the first rotating mechanism 200 drives the turntable 103 to rotate at a certain angle, rotating the cleaned filter screen 107 to the top of the water filter tank 101, while the filter screen 107 that needs to be cleaned is rotated to the top of the sewage tank 102. Then, the flipping mechanism 300 drives the four filter screens 107 to rotate 180 degrees at the same time, so that the side of the filter screen 107 with the impurities adhering to it faces down. Then, the valve on the water inlet pipe 108 (not shown in the figure) is opened to allow the wastewater to continue to flow out for filtration.

[0029] The rinsing mechanism 400 rinses the filter screen 107 to be cleaned from top to bottom. Since the side of the filter screen 107 with impurities attached is facing down, the rinsing action can wash away the impurities adhering to the lower surface of the filter screen 107 and let them fall into the sewage tank 102, thus achieving the purpose of self-cleaning. This not only reduces the labor intensity of workers, but also has a good cleaning effect and reduces the interruption time of wastewater treatment, thus significantly improving the wastewater treatment efficiency.

[0030] Preferably, the first rotating mechanism 200 includes a fixed disk 201 mounted on the outside of two water filter tanks 101 and two sewage tanks 102. A rotating seat 202 is rotatably mounted on the upper surface of the fixed disk 201, and a turntable 103 is mounted on the top of the rotating seat 202. A first driven gear 203 is mounted on the outer surface of the rotating seat 202. A first servo motor 204 is mounted on the outer surface of the fixed disk 201. A first drive gear 205 is mounted on the end of the output shaft of the first servo motor 204. The first drive gear 205 is meshed with the first driven gear 203.

[0031] When the first servo motor 204 is started, its output shaft drives the first drive gear 205 to rotate. Since the first drive gear 205 meshes with the first driven gear 203, it can drive the rotating seat 202 to rotate and drive the turntable 103 to rotate.

[0032] Preferably, the flipping mechanism 300 includes a mounting groove 301 formed on the surface of the turntable 103, the ends of four rotating shafts 105 all pass through the mounting groove 301 and are equipped with driven bevel gears 302, a U-shaped frame 303 is mounted on the top of the turntable 103, a second servo motor 304 is mounted on the upper surface of the U-shaped frame 303, a drive bevel gear 305 is mounted on the end of the output shaft of the second servo motor 304, and the drive bevel gear 305 is simultaneously meshed with the four driven bevel gears 302.

[0033] When the second servo motor 304 is started, its output shaft drives the drive bevel gear 305 to rotate. Since the drive bevel gear 305 is simultaneously engaged with four driven bevel gears 302, it can simultaneously drive the four rotating shafts 105 to rotate, thereby achieving the purpose of driving the four filters 107 to rotate simultaneously.

[0034] Preferably, the flushing mechanism 400 includes a cantilever 401 disposed above the wastewater tank 102. An inlet pipe 402 is rotatably mounted through the cantilever 401. A horizontal pipe 403 is mounted at the bottom of the inlet pipe 402. Multiple nozzles 404 are arranged along the length of the lower surface of the horizontal pipe 403. A rotary joint 405 is mounted at the top of the inlet pipe 402. A water pump 406 is mounted on the upper surface of the base 100. The suction end of the water pump 406 is connected to the filter tank 101, and the output end of the water pump 406 is connected to a flexible hose 407, the end of which is connected to the rotary joint 405. A second rotating mechanism 500 capable of driving the inlet pipe 402 to rotate is provided on the outer surface of the cantilever 401.

[0035] When the water pump 406 is started, its suction end draws water out of the filter tank 101 and delivers it to the inlet pipe 402 through the hose 407 and the water pump 406. Then, multiple nozzles 404 spray the water evenly downwards. At the same time, the inlet pipe 402 is driven to rotate by the second rotating mechanism 500, so that the nozzles 404 can wash the entire surface of the filter screen 107. Therefore, the impurities adhering to the lower surface of the filter screen 107 can be washed away and fall into the sewage tank 102, thus achieving the purpose of self-cleaning.

[0036] Preferably, the second rotating mechanism 500 includes a third servo motor 501 mounted on the end of the cantilever 401, a second drive gear 502 mounted on the end of the output shaft of the third servo motor 501, and a second driven gear 503 mounted on the outer surface of the water inlet pipe 402, the second driven gear 503 meshing with the second drive gear 502.

[0037] When the third servo motor 501 is started, its output shaft drives the second drive gear 502 to rotate. Since the second drive gear 502 and the second driven gear 503 mesh with each other, the second drive gear 502 can drive the water inlet pipe 402 to rotate, so that the nozzle 404 can evenly rinse the surface of the filter screen 107.

[0038] Preferably, an electric push rod 600 is mounted on the upper surface of the base 100, and the end of the telescopic end of the electric push rod 600 is connected to the cantilever 401.

[0039] When the electric push rod 600 is activated, its telescopic end can drive the cantilever 401 to rise and fall. Therefore, during rinsing, the cantilever 401 can be lowered to a lower position, allowing the nozzle 404 to rinse the filter screen 107 at close range, washing away the attached stubborn impurities and improving the rinsing effect.

[0040] Preferably, the upper and lower sides of the mounting frame 106 are provided with a surrounding plate 700.

[0041] By setting up the enclosure 700, the wastewater above the filter screen 107 can be intercepted, preventing the filter screen 107 from becoming clogged, which would lead to poor flow, a rise in liquid level, and overflow from the top of the mounting frame 106.

[0042] Preferably, the outer surface of the water filter tank 101 is connected to the water outlet pipe 800, the outer surface of the sewage tank 102 is connected to the sewage pipe 801, and the height of the water outlet pipe 800 is higher than the height of the suction end of the water pump 406.

[0043] By raising the outlet pipe 800 higher than the suction end of the water pump 406, the water filter tank 101 can maintain a certain water level for the flushing mechanism 400, eliminating the need for additional water resources and reducing costs.

[0044] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
