Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a stirring device in a pretreatment system based on greywater reuse. Background Technology

[0002] Reclaimed water reuse refers to the treatment of urban sewage or industrial wastewater to meet certain water quality standards, and its reuse in urban non-potable water. In the reclaimed water reuse process, the pretreatment system is one of the key links. It is mainly used to remove large particulate impurities, suspended solids, some organic matter and colloids from the raw water to reduce the burden on subsequent treatment processes.

[0003] A search revealed a utility model patent with Chinese patent publication number CN207887014U, which discloses a stirring device in a pretreatment system for recycled water. Fixed platforms are installed on both sides of the outer wall of the stirring drum. An electric telescopic rod is mounted on the upper side of the fixed platform, and the upper side of the electric telescopic rod is assembled with a lifting plate. A stirring motor is installed in the middle of the lower end face of the lifting plate, and the stirring motor is installed with the stirring paddle. The height of the stirring paddle is adjusted by adding the lifting plate, thus facilitating adjustment of the stirring paddle height according to the liquid inside the stirring drum.

[0004] When the above-mentioned device is in use, impurities in the water will inevitably adhere to the cylinder wall and the stirring rack. As the impurities accumulate, the internal space of the stirring cylinder will decrease, and the effect of the stirring rack in driving the water flow will also decrease. Therefore, it is necessary to clean it regularly. The cleaning process is inconvenient and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device in a pretreatment system for recycled water to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stirring device in a pretreatment system for recycled water, comprising a support frame and a stirring drum. The stirring drum is rotatably connected to the inside of the support frame via bearings. A cleaning assembly is installed on the top of the support frame. The cleaning assembly includes a mounting frame 1 fixedly connected to the outer wall of the top of the support frame. Four equally spaced mounting rods are rotatably connected inside the mounting frame 1. A nozzle is fixedly connected to the middle of each of the four mounting rods. A bevel gear is coaxially fixed at both ends of each of the four mounting rods. Adjacent bevel gears mesh with each other. A gear ring 1 is coaxially fixed to the outside of one of the mounting rods. A first transmission assembly adapted to the gear ring 1 is installed on the top of the mounting frame 1. The first transmission assembly includes a gear 1 and a stepper motor. A second transmission assembly is installed outside the stirring drum. The second transmission assembly includes a gear ring 2, a motor 1, and a gear 2.

[0007] It can perform comprehensive cleaning of the inner wall of the mixing drum and the mixing structure. The cleaning process is quick and convenient, ensuring that the device can be put into operation more quickly. Moreover, the staff does not need to directly contact the dirt. The stepper motor drives the first gear to rotate forward at a certain angle and then in the opposite direction. The rotation angle is adjusted according to the diameter of the mixing drum to ensure that the inner wall of the mixing drum can be thoroughly cleaned. The first gear drives the first gear ring and the mounting rod connected to it to rotate through meshing. The mounting rod drives the nozzle to rotate synchronously. The water sprayed from the nozzle outlet will spray the inner wall of the mixing drum and the outer wall of the mixing frame. The cooperation of multiple nozzles can greatly improve the cleaning efficiency. At the same time, the first motor drives the second gear to rotate. The second gear drives the second gear ring and the mixing drum to rotate through meshing, thereby achieving comprehensive cleaning of impurities.

[0008] As a further preferred embodiment of this technical solution, the stepper motor is fixedly installed inside the mounting bracket, the stepper motor is horizontally arranged, the gear is coaxially fixed to the output end of the stepper motor, and the gear meshes with the gear ring.

[0009] As a further preferred embodiment of this technical solution, the second gear ring is coaxially fixed outside the stirring drum, the first motor is fixedly connected inside the support frame, the second gear is coaxially fixed at the output end of the first motor, and the second gear meshes with the second gear ring.

[0010] As a further preferred embodiment of this technical solution, a stirring assembly is installed on the top of the support frame, and the lower half of the stirring assembly extends into the interior of the stirring drum.

[0011] As a further preferred embodiment of this technical solution, the stirring assembly includes a second mounting frame fixedly connected to the top outer wall of the support frame, a stirring paddle rotatably connected to the inner wall of the second mounting frame, a second motor fixedly mounted on the top outer wall of the second mounting frame, the output end of the second motor being coaxially fixed with one end of the top of the stirring paddle, and a stirring frame rotatably sleeved on the outside of the stirring paddle.

[0012] As a further preferred embodiment of this technical solution, a vertically arranged gear rod is rotatably connected inside the mounting frame two, and a gear ring three adapted to the gear rod is coaxially fixed to the top of the outer circumference of the stirring frame. A sprocket is coaxially fixed to the outside of the gear rod and the output end of the motor two, and the two sprockets are fitted with the same chain.

[0013] Start the second motor on the top of the second mounting bracket. The second motor drives the agitator to rotate, which pushes the wastewater at the top downwards. After contacting the bottom wall of the mixing drum, the wastewater returns to the top, thus creating a cycle. The sprocket at the output end of the second motor drives another sprocket to rotate via a chain. The gear rod connected to this sprocket is also driven to rotate. The gear rod meshes and drives the gear ring three and the mixing frame to rotate, so that the wastewater flowing back to the top is stirred again, allowing the wastewater and the agent to mix together more quickly.

[0014] As a further preferred embodiment of this technical solution, the stirring blades on the outside of the stirring frame are provided with several through holes that are evenly distributed.

The rotation angle is adjusted according to the diameter of the mixing drum to ensure that the inner wall of the mixing drum can be thoroughly cleaned. The gear one drives the gear ring one and the mounting rod connected to it to rotate through meshing. The mounting rod drives the nozzle to rotate synchronously. The water sprayed from the nozzle outlet will spray the inner wall of the mixing drum and the outer wall of the mixing frame.

[0023] 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.

[0024] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, a stirring device in a pretreatment system based on greywater reuse includes a support frame 1 and a stirring drum 2. The stirring drum 2 is rotatably connected to the inside of the support frame 1 via bearings. A cleaning component 3 is installed on the top of the support frame 1. The cleaning component 3 includes a mounting bracket 301 fixedly connected to the outer wall of the top of the support frame 1. Four equally spaced mounting rods 302 are rotatably connected inside the mounting bracket 301. A nozzle 303 is fixedly connected to the middle of each of the four mounting rods 302. A bevel gear 304 is coaxially fixed at both ends of each of the four mounting rods 302. Adjacent bevel gears 304 mesh with each other. A gear ring 305 is coaxially fixed to the outside of one of the mounting rods 302. A first transmission component adapted to the gear ring 305 is installed on the top of the mounting bracket 301. The first transmission component includes a gear 306 and a stepper motor 307. A second transmission component is installed on the outside of the stirring drum 2. The second transmission component includes a gear ring 308, a motor 309, and a gear 310.

[0025] Stepper motor 307 is fixedly installed inside mounting bracket 301. Stepper motor 307 is horizontally positioned. Gear 306 is coaxially fixed to the output end of stepper motor 307. Gear 306 meshes with gear ring 305.

[0026] Gear ring 2 308 is coaxially fixed to the outside of the mixing drum 2, motor 1 309 is fixedly connected to the inside of the support frame 1, gear 2 310 is coaxially fixed to the output end of motor 1 309, and gear 2 310 meshes with gear ring 2 308.

[0027] When impurities accumulate to a certain extent on the inner wall of the mixing drum 2, the stepper motor 307 is started. The stepper motor 307 drives the gear 306 to rotate clockwise by a certain angle and then counterclockwise. The rotation angle is adjusted according to the diameter of the mixing drum 2 to ensure that the inner wall of the mixing drum 2 can be thoroughly cleaned. The gear 306 drives the gear ring 305 and the mounting rod 302 connected to it to rotate through meshing. The mounting rod 302 drives the nozzle 303 to rotate synchronously. The water sprayed from the nozzle 303 outlet will spray the inner wall of the mixing drum 2 and the outer wall of the mixing frame 404 (the water pressure must be sufficient to clean the impurities when the water flow reaches the bottom wall of the mixing drum 2). The cooperation of multiple nozzles 303 can greatly improve the cleaning efficiency. At the same time, the motor 309 is started to drive the gear 310 to rotate. The gear 310 drives the gear ring 308 and the mixing drum 2 to rotate through meshing, thereby achieving thorough cleaning of impurities.

[0028] like Figure 1 and Figure 3 As shown, a stirring assembly 4 is installed on the top of the support frame 1, and the lower half of the stirring assembly 4 extends into the interior of the stirring drum 2.

[0029] The stirring assembly 4 includes a second mounting frame 401 fixedly connected to the top outer wall of the support frame 1, a stirring paddle 402 rotatably connected to the inner wall of the second mounting frame 401, a second motor 403 fixedly mounted on the top outer wall of the second mounting frame 401, the output end of the second motor 403 being coaxially fixed with one end of the top of the stirring paddle 402, and a stirring frame 404 rotatably sleeved on the outside of the stirring paddle 402.

[0030] The mounting bracket 401 has a vertically arranged gear rod 406 rotatably connected inside. The top of the outer circumference of the stirring rack 404 is coaxially fixed with a gear ring 405 that matches the gear rod 406. A sprocket 407 is coaxially fixed to the outside of the gear rod 406 and the output end of the motor 403. The two sprockets 407 are fitted with the same chain.

[0031] Start the motor 403 on top of the mounting bracket 401. The motor 403 drives the agitator 402 to rotate. The agitator 402 pushes the sewage from the top downwards, and after contacting the bottom wall of the mixing drum 2, it returns to the top, thus creating a cycle. The sprocket 407 at the output end of the motor 403 drives another sprocket 407 to rotate via a chain. The gear rod 406 connected to this sprocket 407 is driven to rotate. The gear rod 406 drives the gear ring 405 and the agitator 404 to rotate through meshing, so that the sewage flowing back to the top will be agitated again, allowing the sewage and the agent to mix together more quickly.

[0032] like Figure 3 As shown, the stirring blades of the stirring frame 404 are provided with several through holes that are evenly distributed inside. These through holes can increase the flow of liquid during stirring and improve the stirring efficiency.

[0033] This utility model provides a stirring device in a pretreatment system based on greywater reuse, and its specific working principle is as follows:

[0034] When the device is working, wastewater enters the support frame 1 through the inlet pipe installed inside the mounting frame 301. As the external reagent enters, the motor 403 on the top of the mounting frame 401 is started. The motor 403 drives the agitator 402 to rotate. The agitator 402 pushes the wastewater on top downwards, and after contacting the bottom wall of the mixing drum 2, it returns to the top, thus circulating. The sprocket 407 at the output end of the motor 403 drives another sprocket 407 to rotate through the chain. The gear rod 406 connected to this sprocket 407 is driven to rotate. The gear rod 406 drives the gear ring 405 and the mixing frame 404 to rotate through meshing, so that the wastewater flowing back to the top will be agitated again, so that the wastewater and reagent can be mixed together more quickly. When impurities accumulate to a certain extent on the inner wall of the mixing drum 2, the stepper motor 307 is started. The stepper motor 307 drives the gear 306 to rotate clockwise by a certain angle and then counterclockwise. The rotation angle is adjusted according to the diameter of the mixing drum 2 to ensure that the inner wall of the mixing drum 2 can be thoroughly cleaned. The gear 306 drives the gear ring 305 and the mounting rod 302 connected to it to rotate through meshing. The mounting rod 302 drives the nozzle 303 to rotate synchronously. The water sprayed from the nozzle 303 outlet will spray the inner wall of the mixing drum 2 and the outer wall of the mixing frame 404 (the water pressure must be sufficient to clean the impurities when the water flow reaches the bottom wall of the mixing drum 2). The cooperation of multiple nozzles 303 can greatly improve the cleaning efficiency. At the same time, the motor 309 is started to drive the gear 310 to rotate. The gear 310 drives the gear ring 308 and the mixing drum 2 to rotate through meshing, thereby achieving thorough cleaning of impurities.

[0035] 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.
