Technical Field

[0001] This utility model relates to the technical field of wastewater treatment tank cleaning, and in particular to a wastewater treatment tank that is easy to clean. Background Technology

[0002] With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. Against this backdrop, the wastewater treatment industry has become an emerging industry, holding an equally important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. The organic matter in wastewater is extremely unstable and easily decomposes, producing foul odors. Bacteria and pathogens multiply rapidly by using organic matter in domestic wastewater as nutrients, which can lead to the spread of infectious diseases. Wastewater treatment ponds that are easy to clean are used in wastewater treatment. However, in practice, users find it inconvenient to clean the bottom of the treatment pond when maintaining it. Therefore, there is a particular need for a wastewater treatment pond that is easy to clean.

[0003] A wastewater treatment tank with easy cleaning, authorized by announcement number CN220328005U, includes a treatment tank with a fixed block fixedly installed on its surface and a cleaning mechanism provided on the surface of the treatment tank. The cleaning mechanism includes a support frame slidably installed on the surface of the treatment tank, and two first motors fixedly installed on the surface of the support frame. Two connecting rods are fixedly installed at the output ends of the first motors. This easy-to-clean wastewater treatment tank allows users to easily clean the bottom of the treatment tank during maintenance, removing impurities and sludge deposited at the bottom without the need for manual cleaning with tools, reducing user workload and lowering the cleaning cost of the treatment tank.

[0004] However, the cleaning range of the aforementioned easy-to-clean wastewater treatment tank is limited by the size of the disc and brush themselves, which affects the cleaning effect of the treatment tank, and the cleaned sludge is prone to clogging the sewage pipe.

[0005] To address the aforementioned problems, a wastewater treatment pond that is easy to clean is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a wastewater treatment tank that is easy to clean, in order to solve the problem of existing wastewater treatment tanks that are easy to clean as mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment tank that is easy to clean, comprising a tank body, wherein a cleaning component is provided on the top of the tank body and a sewage discharge component is provided on the bottom side of the tank body;

[0008] The cleaning assembly includes a top mounting frame welded to the top of the pool body, a movable frame slidably connected to the top of the top mounting frame, a U-shaped plate welded to the bottom of the movable frame, a U-shaped scraper provided on the outer side of the U-shaped plate and the outer side of the U-shaped scraper in contact with the inner wall of the pool body, a U-shaped tube provided on the inner wall of the U-shaped plate, and nozzles uniformly installed on the surface of the U-shaped tube.

[0009] Preferably, the cleaning assembly further includes a mounting box installed on one side of the top mounting frame. Both ends of the top mounting frame are provided with sliding grooves. Threaded rods are threadedly connected to the bottom of both sides of the movable frame. A connecting rod is rotatably connected to the inner wall of the mounting box. A first bevel gear is installed on one side of the threaded rod, and a second bevel gear meshes with one side of the first bevel gear.

[0010] Preferably, the nozzle's ejection end faces the inner wall of the pool, and the nozzle is sealed to the U-shaped plate.

[0011] Preferably, the threaded rod is disposed on the inner wall of the groove, and the connecting end of the threaded rod passes through the top mounting bracket and extends to the outside of the top mounting bracket to connect with the first bevel gear.

[0012] Preferably, the second bevel gear is sleeved on the surface of the connecting rod, and both the first bevel gear and the second bevel gear are installed inside the mounting box.

[0013] Preferably, the sewage discharge assembly includes a first groove in the middle of one side of the bottom wall of the pool, a sewage discharge box welded to one side of the bottom of the pool, a sewage discharge trough in the inner wall of the sewage discharge box, and a spiral conveyor belt in the inner wall of the sewage discharge trough, the size of which is adapted to the diameter of the sewage discharge trough.

[0014] Preferably, the sewage discharge assembly further includes a second groove in the middle of the top of the sewage discharge box, and the second groove corresponds to the position of the first groove.

[0026] 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.

[0027] Example

[0028] like Figure 1 , 3 As shown, the system includes a pool body 1, a cleaning component 2 on the top of the pool body 1, and a sewage discharge component 3 on the bottom side of the pool body 1. The cleaning component 2 includes a top mounting frame 201 welded to the top of the pool body 1. A movable frame 202 is slidably connected to the top of the top mounting frame 201. A U-shaped plate 203 is welded to the bottom of the movable frame 202. A U-shaped scraper 204 is provided on the outer side of the U-shaped plate 203, and the outer side of the U-shaped scraper 204 contacts the inner wall of the pool body 1. A U-shaped tube 205 is provided on the inner wall of the U-shaped plate 203, and nozzles 206 are evenly installed on the surface of the U-shaped tube 205.

[0029] It should be noted that, in this embodiment, when the movable frame 202 moves, it drives the U-shaped plate 203 welded at the bottom and the U-shaped scraper 204 on the outside to move along the inner wall of the pool 1. The outer side of the U-shaped scraper 204 contacts the pool wall and scrapes off the attached sludge and suspended matter. The U-shaped tube 205 on the inner wall of the U-shaped plate 203 sprays water onto the inner wall of the pool 1 through the nozzle 206. The nozzle 206 faces the inner wall of the pool 1 and is sealed to the U-shaped plate 203, which can prevent impurities from entering the interior of the U-shaped plate 203. The water flow washes away the scraped impurities and makes them fall to the bottom of the pool 1, improving the cleaning effect.

[0030] Furthermore, when the device is started, the movable frame 202 first performs an initial cleaning in a unidirectional motion. At this time, the U-shaped scraper 204 scrapes the impurities uniformly to one side of the pool body 1. The nozzle 206 sprays water at a low pressure to reduce the disturbance of the water flow to the just scraped impurities. After the initial cleaning is completed, the movable frame 202 moves in the opposite direction, and at the same time, the nozzle 206 turns on high pressure to flush the remaining impurities to the bottom of the pool, ensuring that the back and forth motions achieve effective cleaning and that impurities do not accumulate during the back and forth motions.

[0031] Optionally, the U-shaped pipe 205 is connected to an external high-pressure water pipe, and the nozzle 206 adopts a fan-shaped nozzle 206, which can ensure that all areas of the inner wall of the pool 1 can be covered by water flow, thereby improving the rinsing effect. To prevent the nozzle 206 from clogging, a Y-type filter can be installed at the inlet of the high-pressure water pipe to filter impurities from the water flow entering the U-shaped pipe 205. The external components and drive components of this device are all existing mature technologies, and will not be further elaborated here.

[0032] Among them, such as Figure 2 As shown, the cleaning assembly 2 also includes a mounting box 207 mounted on one side of the top mounting bracket 201. Both ends of the top mounting bracket 201 have sliding grooves 208. Threaded rods 209 are threadedly connected to the bottom of both sides of the movable bracket 202. A connecting rod 210 is rotatably connected to the inner wall of the mounting box 207. A first bevel gear 211 is mounted on one side of the threaded rod 209, and a second bevel gear 212 meshes with one side of the first bevel gear 211. A servo motor is located outside the mounting box 207, and its output shaft is fixedly connected to one end of the connecting rod 210, providing power to the entire cleaning assembly 2. The power source consists of a first bevel gear 211 and a threaded rod 209 connected by a key, allowing them to rotate synchronously. A second bevel gear 212 is fitted onto the surface of a connecting rod 210 via an interference fit. A servo motor drives the connecting rod 210 to rotate, which in turn drives the second bevel gear 212 fitted onto its surface to rotate. The second bevel gear 212 meshes with the first bevel gear 211, transmitting rotational power to the threaded rod 209. The threaded rod 209 passes through a groove 208 in the top mounting bracket 201, and through threaded transmission, drives the movable bracket 202 to slide left and right on the top of the top mounting bracket 201.

[0033] like Figure 4 , 5As shown, the sewage discharge assembly 3 includes a first groove 301 opened in the middle of one side of the bottom wall of the pool body 1. A sewage discharge box 302 is welded to one side of the bottom of the pool body 1. A sewage discharge trough 303 is opened in the inner wall of the sewage discharge box 302. A spiral conveyor belt 304 is provided in the inner wall of the sewage discharge trough 303. The size of the spiral conveyor belt 304 is adapted to the diameter of the sewage discharge trough 303. The sewage discharge assembly 3 also includes a second groove 305 opened in the middle of the top of the sewage discharge box 302. The second groove 305 corresponds to the position of the first groove 301. A sewage discharge pipe 306 is provided at the bottom end of the sewage discharge box 302. The inlet end of the sewage discharge pipe 306 is located below the spiral conveyor belt 304.

[0034] It should be noted that in this embodiment, the servo motor is installed outside the sewage tank 302, and the bottom wall of the pool 1 has an inclined structure on both sides. The scraped impurities and sludge in the wastewater are pushed to the first groove 301 by the U-shaped scraper 204, and then fall to the bottom of the first groove 301 under the action of gravity. Then, they enter the sewage trough 303 in the sewage tank 302 through the second groove 305. The servo motor drives the spiral conveyor belt 304 to rotate. Since the size of the spiral conveyor belt 304 is adapted to the diameter of the sewage trough 303, the spiral conveyor belt 304 transports the impurities in the sewage trough 303 from the inlet end of the second groove 305 to the sewage pipe 306. The impurities are pushed to the inlet of the sewage pipe 306 by the spiral conveyor belt 304 and discharged out of the pool through the sewage pipe 306, realizing the centralized treatment of pollutants.

[0035] Since the bottom walls of the pool body 1 on both sides of the first groove 301 are inclined, the inclined structure utilizes the principle of gravity to allow impurities to converge along the inclined surface to the first groove 301, reducing the time impurities stay at the bottom of the pool body 1. Combined with the conveying of the spiral conveyor belt 304, impurities can be quickly discharged out of the pool, improving the overall sewage discharge efficiency.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual appendix Figure 1-5 The mounting box 207 is equipped with a servo motor on its exterior. The servo motor drives the connecting rod 210 to rotate, which in turn drives the second bevel gear 212 sleeved on its surface to rotate. The second bevel gear 212 meshes with the first bevel gear 211, transmitting the rotational power to the threaded rod 209. The threaded rod 209 passes through the slide groove 208 of the top mounting frame 201, and drives the movable frame 202 to slide left and right on the top of the top mounting frame 201 through threaded transmission.

[0038] When the movable frame 202 moves, it drives the U-shaped plate 203 welded at the bottom and the U-shaped scraper 204 on the outside to move along the inner wall of the pool 1. The outer side of the U-shaped scraper 204 contacts the pool wall and scrapes off the attached sludge and suspended matter. The U-shaped tube 205 on the inner wall of the U-shaped plate 203 sprays water onto the inner wall of the pool 1 through the nozzle 206. The nozzle 206 faces the inner wall of the pool 1 and is sealed to the U-shaped plate 203, which can prevent impurities from entering the interior of the U-shaped plate 203. The water flow washes away the scraped impurities and makes them fall to the bottom of the pool 1, improving the cleaning effect.

[0039] The movable frame 202 first performs the initial cleaning in one direction. At this time, the U-shaped scraper 204 scrapes the impurities to one side of the pool body 1. The nozzle 206 sprays water at a low pressure to reduce the disturbance of the water flow to the scraped impurities. After the initial cleaning is completed, the movable frame 202 moves in the opposite direction. At the same time, the nozzle 206 turns on high pressure to flush the remaining impurities to the bottom of the pool, ensuring that the back and forth movement achieves effective cleaning and that impurities do not accumulate during the back and forth movement.

[0040] The scraped-off impurities and sludge in the wastewater are pushed to the first groove 301 by the U-shaped scraper 204, and then fall to the bottom of the first groove 301 under the action of gravity. They then enter the sewage discharge trough 303 in the sewage discharge tank 302 through the second groove 305. The servo motor drives the spiral conveyor belt 304 to rotate. Since the size of the spiral conveyor belt 304 is adapted to the diameter of the sewage discharge trough 303, the spiral conveyor belt 304 transports the impurities in the sewage discharge trough 303 from the inlet end of the second groove 305 to the sewage discharge pipe 306. The impurities are pushed to the inlet of the sewage discharge pipe 306 by the spiral conveyor belt 304 and discharged out of the tank through the sewage discharge pipe 306, realizing the centralized treatment of pollutants.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
