Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to a chemical dosing device for rural wastewater treatment facilities. Background Technology

[0002] Rural sewage treatment involves removing and degrading harmful substances and pollutants from sewage to render it harmless. Rural sewage treatment should prioritize the selection of mature, reliable technologies suitable for rural characteristics and practical sewage treatment practices. Depending on the actual situation, rural sewage treatment can neutralize water for agricultural use, thereby achieving reuse and environmentally friendly degradation before discharge. Rural sewage is the most typical source of pollutants in rural areas.

[0003] In existing technologies, wastewater purification typically uses flocculants. Flocculants can aggregate fine particles and natural colloids in water into large flocs, thereby purifying wastewater. However, the high-speed rotating blades cause polymer shear degradation of the flocculant, altering its properties and rendering it ineffective. If the flocculant is not stirred, it is difficult to fully mix it with the wastewater. Excessive flocculant aggregation prevents it from fully exerting its effects, resulting in waste.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 7 As shown, the present invention provides a dosing device for rural sewage treatment facilities, including a cylinder 1. The inside of the cylinder 1 is arranged from top to bottom as follows: funnel 25, a material distribution mechanism, a peristaltic drive device, a peristaltic execution component, and funnel 4.

[0035] The top of the cylinder 1 is provided with a feeding port 28, the top of the funnel 25 is connected to the feeding port 28, and the bottom of the funnel 25 is connected to the material distribution mechanism.

[0036] The dispensing mechanism is used to control the amount of medicine added;

[0037] The peristaltic actuator is located inside the funnel 4. The peristaltic actuator is used to mix the agent and the sewage. The peristaltic actuator is driven by a peristaltic drive device.

[0038] The top of the funnel 4 is fixedly connected to the inner wall of the cylinder 1, and the bottom of the funnel 4 penetrates the bottom wall of the cylinder 1 and is fixedly connected to the drain outlet 3.

[0039] A water inlet 30 is fixedly installed on the side wall of the cylinder 1, and the water inlet 30 is connected to the upper part of the funnel 4.

[0040] The feeding mechanism allows for precise control of the dosage and quantitative addition of chemicals to wastewater, thereby improving the accuracy of the mixing ratio and the wastewater treatment effect. Simultaneously, the peristaltic drive device drives the peristaltic actuator to agitate the water body, allowing the chemicals to be evenly mixed into the wastewater along with the agitated water flow. This avoids the problem of chemical property damage caused by the traditional method of forcibly stirring with an impeller.

[0041] This invention allows the medicine to be evenly mixed into the sewage, ensuring the efficacy of the medicine.

[0042] Furthermore, the material distribution mechanism includes a guide cylinder 24 fixedly connected to the bottom end of the funnel 25. An annular partition 23 is fixedly sleeved at the bottom end of the guide cylinder 24. The outer edge of the annular partition 23 is fixedly connected to the inner wall of the cylinder 1. A motor 29 is installed at the middle of the top end of the cylinder 1. A rotating rod 19 is fixedly connected to the output shaft of the motor 29. The rotating rod 19 is coaxially arranged with the guide cylinder 24. A spiral blade 20 is fixedly sleeved on the rotating rod 19. The spiral blade 20 slides in contact with the inner wall of the guide cylinder 24. A uniform distribution component is provided inside the top end of the guide cylinder 24. The uniform distribution component is located above the spiral blade 20.

[0043] The motor 29 drives the rotating rod 19 to rotate, and the rotating rod 19 drives the spiral blade 20 to rotate inside the guide cylinder 24. This allows the agent in the funnel 25 to be added to the sewage under the conveying of the spiral blade 20. At the same time, it can prevent the agent from clumping on the inner wall of the guide cylinder 24 and avoid the problem of affecting the sewage treatment effect due to the deviation of the dosage of the agent added to the sewage.

[0044] Furthermore, the equalizing component includes a partition plate 33 slidably sleeved on the rotating rod 19. The outer edge of the partition plate 33 is fixedly connected to the inner wall of the top of the guide cylinder 24. A second discharge port 34 is opened on the partition plate 33. A distribution plate 31 is fixedly sleeved on the rotating rod 19. The side wall of the distribution plate 31 is slidably engaged with the inner wall of the guide cylinder 24. A first discharge port 32 is opened on the distribution plate 31. The first discharge port 32 is correspondingly arranged with the second discharge port 34. The top of the distribution plate 31 is in sliding contact with the bottom of the partition plate 33. A pusher plate 35 is fixedly connected to the rotating rod 19. The bottom of the pusher plate 35 is in sliding contact with the top of the partition plate 33. The pusher plate 35 is located directly above the first discharge port 32.

[0045] The motor 29 drives the rotating rod 19 to rotate, which in turn drives the pusher plate 35 and the distributing plate 31 to rotate synchronously. When the discharge port 1 32 and discharge port 2 34 gradually overlap, the pusher plate 35 pushes the medicine to discharge port 2 34 and then through discharge port 1 32 into the sewage. The pusher plate 35 makes it easier for the medicine to enter discharge port 2 34. By controlling the speed of the motor 29, the time interval for adding the medicine can be controlled, and the distance between discharge port 1 32 and discharge port 2 34 can be set. The size of the opening 34 determines the amount of agent added. Furthermore, an arc-shaped spring is fixedly connected to one side of the pusher plate 35. The length of the arc-shaped spring is less than the length of the discharge port 34. The arc-shaped spring abuts against the top of the partition plate 33. When the arc-shaped spring passes through the discharge port 34, one end of the arc-shaped spring loses contact with the partition plate 33. The arc-shaped spring begins to recover and pushes the agent in the discharge port 34, so that the agent in the discharge port 34 passes smoothly through the discharge port 32 and falls into the sewage.

[0046] Furthermore, the peristaltic drive device includes several compression components arranged circumferentially along the cylinder 1. The compression components are fixedly installed on the inner wall of the cylinder 1 at equal intervals, and the compression components are located between the annular partition 23 and the funnel 4. The compression components are connected to the peristaltic actuator through air pipes. The compression components are used to control the total amount of gas in the peristaltic actuator. The bottom end of the rotating rod 19 is fixedly connected to a vertical rod 37. Two supports 21 are vertically connected to the vertical rod 37. A roller 22 is rotatably connected between the two supports 21. The roller 22 is located at the end of the support 21 away from the vertical rod 37. The roller 22 is in contact with the compression components.

[0047] The motor 29 drives the rotating rod 19 to rotate, which in turn drives the bracket 21 and the roller 22 to rotate and compress the compression component. This compresses the gas in the compression component and delivers it to the peristaltic actuator through the air pipe. When the roller 22 disengages from the compression component, the compression component returns to its original position and draws the gas back from the peristaltic actuator. This controls the total amount of gas in the peristaltic actuator, enabling the peristaltic actuator to move and thus causing the water body to undulate.

[0048] Furthermore, the compression assembly includes two supports 14 vertically fixedly connected to the inner wall of the cylinder 1. The two supports 14 are arranged parallel to each other along the vertical direction of the cylinder 1, and grooves 15 are provided on opposite sides of the two supports 14. A pressure plate 16 is provided between the two supports 14. Limiting posts 17 are fixedly connected to both ends of the pressure plate 16. The pressure plate 16 is slidably mounted on the two supports 14 through the limiting posts 17. A spring 18 is provided between the pressure plate 16 and the cylinder 1. One end of the spring 18 is fixedly connected to the inner wall of the cylinder 1, and the other end of the spring 18 is fixedly connected to the pressure plate 16. A flexible sealing bag 13 is fitted on the spring 18. One end of the flexible sealing bag 13 is fixedly connected to the inner wall of the cylinder 1, and the other end of the flexible sealing bag 13 is fixedly connected to the pressure plate 16. One end of an auxiliary plate 36 is rotatably connected to both ends of the pressure plate 16. The other end of the auxiliary plate 36 is slidably connected to the inner wall of the cylinder 1. The flexible sealing bag 13 is connected to the peristaltic actuator through an air pipe.

[0049] An auxiliary plate 36 is rotatably connected to the pressure plate 16 to form a ramp, allowing the roller 22 to roll onto the pressure plate 16. The roller 22 presses the pressure plate 16 against the elastic force of the spring 18, bringing it closer to the inner wall of the cylinder 1. At this time, the spring 18 is compressed, reducing the distance between the pressure plate 16 and the inner wall of the cylinder 1. This allows the gas in the flexible sealing bag 13 to be discharged through the air pipe onto the peristaltic actuator. The increased gas volume within the peristaltic actuator causes it to expand. As the roller 22 moves forward along the pressure plate 16 and disengages from it via the second auxiliary plate 36, the spring 18 pushes the pressure plate 16 back to its original position, drawing the gas back into the flexible sealing bag 13. The peristaltic actuator then contracts, causing it to move in the wastewater, agitating the wastewater and achieving a uniform and thorough mixing of the agent and wastewater. This peristaltic method ensures thorough mixing of the agent and wastewater while preventing shear degradation of the polymer formed by the mixture, thus avoiding issues that could affect the efficacy of the drug.

[0050] Furthermore, the peristaltic actuator includes airbag 5 and airbag 8, which are fixedly installed on the inner wall of funnel 4 from top to bottom. Both airbag 5 and airbag 8 are annular structures, and there is a gap between airbag 5 and airbag 8. The air tube includes a main air tube 12 fixedly connected to the flexible sealing bag 13. Several branch air tubes 10 and several branch air tubes 21 are fixedly connected to the main air tube 12. The ends of several branch air tubes 10 are connected to airbag 5, and the ends of several branch air tubes 21 are connected to airbag 8.

[0051] In this embodiment, the first air distribution tube 10 and the second air distribution tube 11 are connected to the first airbag 5 and the second airbag 8 respectively at equal intervals.

[0052] By using the equally spaced air distribution pipes 10 and 11, the airbags on the corresponding air paths can expand and contract synchronously, preventing the airbag body from collapsing locally and losing its peristaltic properties.

[0053] Furthermore, several disturbance plates 1 6 and several disturbance plates 2 7 are fixedly connected to the inner edge of airbag 1 5. The length of disturbance plate 2 7 is less than the length of disturbance plate 1 6. Disturbance plates 2 7 and disturbance plate 1 6 are alternately arranged at equal intervals on airbag 1 5; several disturbance plates 3 9 are fixedly connected to the inner edge of airbag 2 8 at equal intervals.

[0054] In this embodiment, the end of the disturbance plate 6 away from the airbag 5 is in contact with the outer wall of the airbag 8.

[0055] By alternately compressing and restoring several flexible sealing bags 13, airbag 1 5 and airbag 2 8 repeatedly expand and contract. Airbag 1 5 drives several disturbance plates 1 6 and several disturbance plates 2 7 to swing up and down in the sewage. Airbag 2 8 drives several disturbance plates 3 9 to swing up and down. The end of disturbance plate 1 6 away from airbag 1 5 contacts the outer wall of airbag 2 8. When airbag 2 8 expands, it applies a counter-thrust force to disturbance plate 1 6, further increasing the swing amplitude of disturbance plate 1 6.

[0056] By alternately setting several disturbance plates 6, several disturbance plates 7, and several disturbance plates 9, and by using several disturbance plates 6 and several disturbance plates 7 of different lengths, water bodies at different depths can be disturbed, thereby increasing the disturbance amplitude and thus increasing the mixing speed of the reagent and the wastewater.

[0057] Furthermore, several connecting rods 27 are fixedly connected to the rotating rod 19 along the circumferential direction. The connecting rods 27 are located inside the second funnel 25. A scraper 26 is fixedly connected to the end of the connecting rod 27 away from the rotating rod 19. The scraper 26 is inclined and slides in contact with the inner wall of the second funnel 25.

[0058] Motor 29 drives rotating rod 19 to rotate, and rotating rod 19 drives connecting rod 27 and scraper 26 to rotate, so as to remove the medicine on the inner wall of funnel 25 and prevent the medicine from clumping.

[0059] Furthermore, to improve stability, several support feet 2 are fixedly installed at the bottom of the cylinder 1.

[0060] Furthermore, both the drain outlet 3 and the inlet 30 are equipped with electric valves, a liquid level sensor is installed on the inner wall of the funnel 4, and a controller is installed on the cylinder 1. The liquid level sensor, electric valve, and motor 29 are all electrically connected to the controller.

[0061] By controlling the opening and closing time of the electric valves on the drain outlet 3 and the inlet 30, the dynamic balance of the sewage volume in the cylinder 1 can be controlled. By controlling the speed of the motor 29, the amount of agent added can be controlled, further improving the accuracy of the agent-sewage ratio and ensuring the optimal dosage of the agent.

[0062] The chemical dosing device for rural sewage treatment facilities provided by this invention operates as follows: During use, chemicals are poured into the inlet and sealed with a cap. Sewage is then introduced. The controller closes the electric valve on the drain outlet 3 and simultaneously opens the electric valve on the inlet 30, allowing water to accumulate in the funnel 4. A liquid level sensor monitors the water level and transmits this information to the controller. When a preset value is reached, the controller closes the electric valve on the inlet 30 and rotates the motor 29 to add chemicals. Multiple flexible sealing bags 13 begin to compress and retract, while airbags 5 and 8 intermittently expand and contract, disturbing the sewage and ensuring thorough mixing of the chemicals. After the preset number of rotations of the motor 29 is reached, the controller stops the motor and closes the electric valve on the drain outlet 3 to drain the sewage. This process is repeated to complete the chemical dosing of the sewage. This invention is simple to operate, highly automated, and can prevent the agent from sticking to the wall and clumping by using a single motor 29. It also achieves the technical effects of uniform addition of the agent, disturbance of the water body, and thorough mixing of the agent and sewage. It requires less power source input, reduces the failure rate, improves the operational reliability of the device, and reduces operating costs.
