Description

Technical Field

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

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It is mainly water used in daily life. It contains a lot of organic matter and is relatively easy to treat. Among the water pollution caused by human production activities, industrial water pollution is the most serious. For example, industrial wastewater contains many pollutants and has a complex composition. It is not only difficult to purify in water, but also relatively difficult to treat.

[0003] At present, the treatment method of artificially adding chemicals is more common in sewage treatment. The principle is to use the chemical reaction between the chemical and the chemical components in the sewage to separate heavy metal ions and impurities and adjust the pH value of the water to the normal range.

[0004] Existing technology publication CN216191306U patent document provides an automatic dosing device for medical wastewater. When it is necessary to add chemicals to the wastewater tank, the free end of the electric telescopic rod drives the vertical rod to rise. Under the linkage of the connecting rod, the second sliders on both sides and the sealing plate move away from the dispensing pipe, the dispensing pipe opens, and the chemicals fall naturally into the wastewater tank under the action of gravity. After the dosing is completed, the free end of the electric telescopic rod is controlled to drive the vertical rod to fall, so that the sealing plate abuts the bottom of the dispensing pipe, thus completing one dosing. The structure is simple and the operation is convenient. It saves manual labor in the process of adding chemicals to the wastewater tank and avoids the operator from close contact with the irritating gases produced by the chemical reaction in the wastewater tank, thereby improving the personal safety of the operator.

[0005] The existing dosing devices described above directly pour the chemical solution into the wastewater tank when adding chemicals. If the solution remains in the tank for an extended period, sedimentation may occur, resulting in a concentrated solution that diffuses slowly and unevenly, thus reducing the wastewater purification effect. Furthermore, the lack of a stirring device in the dosing device means that the solution may precipitate out and remain on the inner wall of the tank, leading to uneven concentration and affecting the wastewater treatment effect. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a wastewater dosing treatment device. During wastewater dosing treatment, the device can drive the reaction tank to rotate the internal wastewater, which, in conjunction with the eccentric stirring of the stirring shaft, increases the diffusion rate of the chemical solution. The chemical solution diffuses into the wastewater through the outlet of the stirring shaft, thereby increasing the reaction rate.

[0007] This utility model is achieved through the following technical solution:

[0008] A wastewater dosing treatment device is provided, including a base and a reaction tank. A driving pulley and a driven pulley, parallel to the base plane, are rotatably mounted on the base via a rotating shaft. The driving pulley and the driven pulley are connected by a synchronous belt drive. A drive motor for driving the driving pulley is mounted on the base via a support. The reaction tank, with its upper open portion, is fixed to the driven pulley. A gantry frame is connected to the base and located above the reaction tank. A stirring shaft and a dosing tank are respectively installed on the crossbeam of the gantry frame. The stirring shaft is vertically rotatably mounted on the bottom surface of the crossbeam of the gantry frame. The lower end of the stirring shaft extends into the reaction tank, and the upper end of the stirring shaft passes through the crossbeam and is connected to a stirring motor on the crossbeam. A cavity is provided inside the stirring shaft along its length, and a dosing outlet communicating with the cavity is evenly distributed on the surface of the stirring shaft. A dosing pipe is connected to the upper end of the stirring shaft via a rotating joint. The dosing pipe is connected to the outlet of the dosing tank via a dosing pump.

[0009] Furthermore, the stirring shaft is located between the central axis of the reaction vessel and the peripheral wall of the reaction vessel.

[0010] The stirring shaft is located between the central axis of the reaction tank and the inner peripheral wall of the reaction tank, making it eccentrically positioned within the reaction tank. This allows for eccentric stirring of the wastewater as the reaction tank rotates, which helps improve stirring efficiency.

[0011] Furthermore, the direction of rotation of the stirring shaft is opposite to the direction of rotation of the reaction vessel.

[0012] The stirring shaft rotates in the opposite direction to the reaction vessel, which can improve stirring efficiency.

[0013] Furthermore, the dosing tank is equipped with a stirring scraper assembly, which includes a double-threaded screw that is horizontally rotatably installed on the upper part of the dosing tank, and a lifting motor installed on the outside of the dosing tank and connected to one end of the double-threaded screw. The two ends of the double-threaded screw are respectively rotatably connected to moving blocks, and the bottom of each moving block is hinged to a connecting rod. A lifting plate is hinged between the two connecting rods. A rotary motor is installed on the lifting plate, and the output end of the rotary motor is vertically connected to a fixed shaft. Scrapers that are spaced apart and in contact with the inner wall of the dosing tank are vertically connected to the fixed shaft.

[0014] The dosing tank is equipped with a stirring scraper assembly. During dosing, the lifting motor drives a double-rotating screw to rotate, causing two moving blocks to move closer or further apart. This, in turn, moves the rotary motor and fixed shaft on the lifting plate up and down. The scraper on the fixed shaft scrapes the inner wall of the dosing tank to prevent drug residue from remaining on the tank wall. Simultaneously, the rotary motor driving the fixed shaft to rotate the scraper ensures more uniform mixing of the drug solution within the dosing tank.

[0015] Furthermore, the reaction vessel is equipped with a cover plate at its opening, with a pre-drilled opening for the stirring shaft to pass through. A screw is vertically rotatably connected to the center of the upper surface of the cover plate, and the upper part of the screw passes through the midpoint of the crossbeam and is threadedly connected to the crossbeam. A handwheel is installed on the upper part of the screw on the crossbeam.

[0016] The open end of the reaction vessel is equipped with a liftable cover plate, which is raised and lowered by rotating a screw driven by a handwheel. The cover plate can be lowered during chemical addition and stirring to prevent wastewater from splashing out and contaminating the ground.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses a drive motor to rotate the reaction tank and an eccentric stirring shaft to stir the wastewater. At the same time, the chemical solution in the dosing tank is pumped into the inner cavity of the stirring shaft by a dosing pump and discharged into the stirred wastewater through the outlet. Wastewater dosing can be completed during the stirring process. It not only has high stirring efficiency but also fast dosing reaction speed, which can significantly improve the dosing reaction rate and thus improve the wastewater treatment speed.

[0019] The dosing tank is equipped with a reciprocating lifting fixed shaft, on which a scraper is vertically connected. The lifting and lowering of the fixed shaft, combined with the rotation and scraping motion of the scraper, not only accelerates the stirring of the chemical solution to ensure its full dissolution, but also effectively prevents chemical residue from remaining on the inner wall of the dosing tank, thereby improving the uniformity of the chemical solution and ensuring the efficiency of wastewater treatment.

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figures 1 to 5 As shown, a wastewater dosing treatment device includes a base 1 and a reaction tank 2. A drive pulley 6 and a driven pulley 5, parallel to the plane of the base 1, are rotatably mounted on the base 1 via a rotating shaft. The drive pulley 6 and the driven pulley 5 are connected by a synchronous belt 7. A drive motor 4 for driving the drive pulley 6 is mounted on the base 1 via a support 3. The reaction tank 2, with its upper open portion, is fixed to the driven pulley 5. A gantry frame 10, located above the reaction tank 2, is connected to the base 1. A stirring shaft 8 and a dosing tank 11 are respectively installed on the crossbeam 15 of the gantry frame 10. The stirring shaft 8 is vertically rotatably mounted on the bottom surface of the crossbeam 15 of the gantry frame 10. The stirring shaft 8 is located between the central axis of the reaction tank 2 and the peripheral wall of the reaction tank 2, so that when the reaction tank 2 rotates, the stirring shaft 8 can eccentrically stir the wastewater inside the reaction tank 2, improving the stirring efficiency.

[0029] In this embodiment, the rotation direction of the stirring shaft 8 is opposite to the rotation direction of the reaction vessel 2.

[0030] The lower end of the stirring shaft 8 extends into the reaction tank 2, and the upper end of the stirring shaft 8 passes through the crossbeam 15 and is connected to the stirring motor 13 on the crossbeam 15. A cavity 28 is provided inside the stirring shaft 8 along its length direction, and a drug outlet 27 communicating with the cavity 28 is evenly opened on the surface of the stirring shaft 8. The upper end of the stirring shaft 8 is connected to a drug dosing pipe 26 through a rotary joint 12. The drug dosing pipe 26 is connected to the outlet of the drug dosing tank 11 through a drug dosing pump 17.

[0031] The dosing tank 11 is equipped with a stirring scraper assembly, which includes a double-threaded screw 19 that is horizontally rotatably installed on the upper part of the dosing tank 11, and a lifting motor 18 installed on the outside of the dosing tank 11 and connected to one end of the double-threaded screw 19. The two ends of the double-threaded screw 19 are respectively rotatably connected to moving blocks 20. The bottom of each moving block 20 is hinged to a connecting rod 22. A lifting plate 23 is hinged between the two connecting rods 22. A rotary motor 21 is installed on the lifting plate 23. The output end of the rotary motor 21 is vertically connected to a fixed shaft 25. Scrapers 24, which are spaced apart and in contact with the inner wall of the dosing tank 11, are vertically connected to the fixed shaft 25.

[0032] To prevent wastewater from splashing out of the reaction tank 2 during the dosing process, a cover plate 9 is provided at the opening of the reaction tank 2. The cover plate 9 has a pre-reserved opening for the stirring shaft 8 to pass through. A screw 16 is vertically rotatably connected to the center of the upper surface of the cover plate 9. The upper part of the screw 16 passes through the midpoint of the length of the crossbeam 15 and is threadedly connected to the crossbeam 15. A handwheel 14 is installed on the upper part of the screw 16 and the crossbeam 15.

[0033] The working process of this utility model:

[0034] In use, the wastewater to be treated is introduced into the reaction tank 2. The drive motor 4 is started, and the driven pulley 5 is driven by the active pulley 6 and the synchronous belt to rotate the reaction tank 2. At the same time, the lifting motor 18, the stirring motor 13, the rotating motor 21, and the dosing pump 17 are started. The chemical solution in the dosing tank 11 is pumped into the inner cavity 28 of the stirring shaft 8 by the dosing pump 17 and discharged into the wastewater in the reaction tank 2 through the outlet 27. When the reaction tank 2 rotates, the eccentric stirring of the stirring shaft 8 can improve the stirring efficiency. At the same time, the chemical solution is discharged from the outlet 27, which allows the chemical solution to diffuse from the inside of the wastewater. With the stirring action, the contact area between the chemical solution and the wastewater and the reaction speed are greatly increased, which helps to complete the chemical reaction efficiently and improve the wastewater treatment rate.

[0035] The chemical solution in the dosing tank 11 is prone to precipitating residue after prolonged use. By setting a rotary motor 21 to drive the fixed shaft 25 to rotate, the scraper 24 on the fixed shaft 25 rotates continuously to stir the chemical solution to improve solubility and prevent residue precipitation. At the same time, the lifting motor 18 drives the double-rotating screw 19 to rotate forward and backward. The two moving blocks can move closer or further apart to drive the lifting plate below to move up and down, which in turn drives the fixed shaft 25 and the scraper 24 on the fixed shaft 25 to move up and down to scrape the inner wall of the dosing tank 11, remove the residue remaining in the dosing tank 11, prevent the residue from solidifying on the inner wall of the dosing tank 11, improve the uniformity of the chemical solution in the dosing tank 11, and further improve the sewage purification effect.
