Description
Technical Field
[0001] This utility model relates to the field of chemical dosing equipment technology, and in particular to chemical dosing equipment for treating washing wastewater. Background Technology
[0002] In the field of wastewater treatment, washing wastewater, due to its complex composition and high pollutant content, requires precise addition of chemicals using dosing equipment to achieve effective purification. The performance of the dosing equipment directly affects the efficiency and quality of wastewater treatment and is a key piece of equipment to ensure the stable operation of the wastewater treatment system.
[0003] Currently, wastewater treatment dosing equipment is widely used in various treatment scenarios. Existing dosing equipment mostly employs traditional stirring and dosing methods, with the coordination of chemical dosing and stirring relying on manual control. In actual operation, this method struggles to accurately match the optimal ratio of wastewater to chemicals under different operating conditions in real time, resulting in room for improvement in chemical utilization efficiency. Furthermore, most chemical tank structures are designed primarily for chemical storage and transport, with insufficient consideration given to the prevention and treatment of chemical residues and adhesion to the inner walls during long-term use. When chemicals adhere and dry on the inner wall of the tank, it increases the difficulty of cleaning and maintenance, affecting the continuous and stable operation of the equipment. To address this technical problem, this application proposes a dosing device for wastewater treatment. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dosing device for wastewater treatment. This invention integrates stirring and quantitative dosing through a motor-linked structure, accurately controlling the reagent ratio. The built-in linkage cleaning device in the tank automatically cleans the dried reagent on the inner wall, reducing maintenance and ensuring stable and efficient wastewater treatment.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A dosing device for wastewater treatment includes a tank and a panel. The tank is fixedly connected to the lower side of the panel. An inlet pipe is fixedly connected to the right side of the tank, and an outlet pipe is fixedly connected to the left side of the tank. A valve is fixedly connected to the outer wall of the outlet pipe. A filter screen is fixedly connected inside the tank. A rotating assembly is installed inside the panel, and a rotating shaft is rotatably connected inside the panel. An agitator is fixedly connected to the lower side of the rotating shaft. A motor is fixedly connected to the upper side of the panel, and a medicine tank is fixedly connected to the upper side of the panel. A cover plate is threadedly connected to the upper side of the medicine tank, and a cleaning assembly is installed inside the cover plate. A feed inlet is fixedly connected to the lower side of the medicine tank.
[0007] Furthermore, the cleaning component includes a rubber sleeve fixedly connected to the upper side of the cover plate, a baffle fixedly connected to the upper side of the rubber sleeve, a rotating rod disposed inside the baffle, and a scraper fixedly connected to the lower side of the rotating rod.
[0008] Furthermore, the rotating assembly includes a circular plate fixedly connected to the rotating end of the motor, an auxiliary plate rotatably connected inside the box plate, a second bevel gear fixedly connected to the lower side of the auxiliary plate, a first bevel gear meshing with the left side of the second bevel gear, and an auger fixedly connected to the left side of the first bevel gear.
[0009] Furthermore, a sleeve is fixedly connected to the lower side of the cover plate, the sleeve is sleeved on the outside of the rotating rod, and a fixed ball is fixedly connected to the lower side inside the sleeve.
[0010] Furthermore, a push plate is rotatably connected to the upper side of the rotating rod, and a spring is sleeved on the outer wall of the rotating rod.

[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the built-in linkage cleaning device of the medicine tank allows the scraper under the cover to effectively peel off and collect the dried medicine adhering to the inner wall of the medicine tank when the operator presses the actuating plate, solving the problem of medicine residue remaining on the inner wall of traditional equipment. After the auxiliary plate is released, the device automatically resets, which does not affect the subsequent dosing process, ensures that the inside of the medicine tank remains clean at all times, reduces the frequency of manual maintenance, extends the service life of the equipment, and provides a strong guarantee for the continuity and reliability of sewage treatment.
[0015] 2. In this invention, the equipment uses a motor to drive a circular plate to rotate, which simultaneously drives the fan blades and auxiliary plate to rotate, creating a linkage mechanism between the stirring rod and the auger. This design allows for precise control of the dosage based on stirring requirements, ensuring that the reagent and wastewater maintain an optimal ratio and are uniformly added under different operating conditions, avoiding the problem of slow dissolution and poor results caused by adding too much reagent at once.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a dosing device for wastewater treatment, comprising a housing 1 and a panel 5. The housing 1 is fixedly connected to the lower side of the panel 5. An inlet pipe 2 is fixedly connected to the right side of the housing 1, and an outlet pipe 4 is fixedly connected to the left side of the housing 1. A valve 3 is fixedly connected to the outer wall of the outlet pipe 4. A filter screen 14 is fixedly connected inside the housing 1. A circular plate 23 is provided inside the panel 5. An auxiliary plate 21 is rotatably connected inside the panel 5. A bevel gear 20 is fixedly connected to the lower side of the auxiliary plate 21. A bevel gear 19 is meshed with the left side of the bevel gear 20. An auger 22 is fixedly connected to the left side of the bevel gear 19. A rotating shaft 12 is rotatably connected inside the box plate 5. A stirring blade 13 is fixedly connected to the lower side of the rotating shaft 12. A motor 6 is fixedly connected to the upper side of the box plate 5. A medicine tank 11 is fixedly connected to the upper side of the medicine tank 11. A cover plate 7 is threadedly connected to the upper side of the medicine tank 11. A rubber sleeve 9 is installed inside the cover plate 7. A baffle 18 is fixedly connected to the upper side of the rubber sleeve 9. A rotating rod 10 is installed inside the baffle 18. A scraper 15 is fixedly connected to the lower side of the rotating rod 10. A feed inlet is fixedly connected to the lower side of the medicine tank 11.
[0024] Specifically, first, rotate the cover plate 7 out and put the cleaning agent into the medicine tank 11. Then rotate the cover plate 7 to fill the medicine tank. When operating the device, the sewage pipe can be connected to the inlet pipe 2, and the treated water pipe can be connected to the outlet pipe 4. When the sewage is discharged into the device, it will enter the filter screen 14. Start the motor 6 to rotate. The motor 6 will drive the circular plate 23 to rotate, and the circular plate 23 will drive the rotating shaft 12 on the lower side to rotate, thereby driving the stirring blade 13 to rotate, so that the sewage and the medicine inside the device can be fully mixed. During the rotation of the circular plate 23, the push rod 24 will be driven to rotate. Because the circular plate 23 and the push rod 24 are in close contact, and the circular plate 23 has a notch, the push rod 24 will rotate when the circular plate 23 rotates. The protrusion at the front of rod 24 enters the strip groove inside auxiliary plate 21, providing rotational power to auxiliary plate 21. After circular plate 23 rotates half a revolution, push rod 24 in strip groove will leave auxiliary plate 21, causing auxiliary plate 21 to lose power. When auxiliary plate 21 rotates, it drives the lower bevel gear 20 to rotate, and bevel gear 20 drives the transverse auger 22 to rotate, allowing the internal agent to be transported to the discharge port inside auger 22 for better mixing with sewage. The powdered agent can be evenly added at a precise and constant ratio according to the stirring rod speed. This precise addition method ensures that sewage and agent can fully contact and react during mixing, greatly improving the efficiency and purification effect of sewage treatment. When cleaning the medicine container 11, press the push plate 8. The rotating rod 10 will move downwards. Because the sleeve 17 has a fixed ball 25 inside, and the inner wall of the rotating rod 10 rotates, the rotating rod 10 will hit the fixed ball 25 during its downward movement. The fixed ball 25 is fixed, so the rotating rod 10 will rotate during its downward movement, and will drive the fixed ball 25 to rotate, thereby cleaning the adhering substances on the inner wall of the medicine container 11. The upper side of the rotating rod 10 is fixed with a baffle 18, and the sleeve 17 has a spring 16 inside. Therefore, during the pressing process, the baffle 18 will compress the spring 16. So after releasing the pressure, the device will rotate upwards along the original path.
[0025] Reference Figure 2 A sleeve 17 is fixedly connected to the lower side of the cover plate 7. The sleeve 17 is fitted onto the outside of the rotating rod 10, and a fixed ball 25 is fixedly connected to the lower side of the inside of the sleeve 17. A pressing plate 8 is rotatably connected to the upper side of the rotating rod 10, and a spring 16 is fitted onto the outer wall of the rotating rod 10. A push rod 24 is fixedly connected to the front side of the circular plate 23, and a protrusion is fixedly connected to the front side of the push rod 24. A rotating shaft 12 is fixedly connected to the lower side of the circular plate 23.
[0026] Specifically, the sleeve 17 and the rotating rod 10, together with the internal fixed ball 25, provide a rotational basis for cleaning the inner wall of the medicine tank 11. When the pressing and actuating plate 8 moves the rotating rod 10 downward, the inner wall of the rotating rod 10 contacts the fixed ball 25. With the fixed ball 25 stationary, the rotating rod 10 is forced to rotate, thereby driving the scraper 15 to scrape off the deposits on the inner wall of the medicine tank 11. The spring 16 is sleeved on the outer wall of the rotating rod 10. When the pressing and actuating plate 8 is pressed, the baffle 18 compresses the spring 16. After releasing, the elastic potential energy of the spring 16 causes the rotating rod 10 and the scraper 15 to rotate upward along the original path, completing the cleaning operation. The push rod 24 and its protrusion on the front side of the circular plate 23 play a key role when the circular plate 23 rotates. The protrusion can be embedded in the internal slot of the auxiliary plate 21 to provide rotational power to the auxiliary plate 21, thereby driving the auger 22 to rotate intermittently and achieve precise dosing of the medicine. The rotating shaft 12 is fixed to the lower side of the circular plate 23 to ensure that when the motor 6 drives the circular plate 23 to rotate, it can synchronously drive the rotating shaft 12 and the stirring blade 13 to achieve full mixing of sewage and chemicals.
[0027] Working Principle: The motor 6 is started, driving the rotating shaft 12 to rotate. The stirring blade 13 fixed to the lower side of the rotating shaft 12 rotates accordingly, ensuring thorough mixing of wastewater and chemicals within the tank 1. Simultaneously, the motor 6 drives the circular plate 23 to rotate. During the rotation of the circular plate 23, the push rod 24 fixed to its front side also rotates. Due to the special structure of the push rod 24 and the auxiliary plate 21, the protrusion in front of the push rod 24 intermittently enters the strip groove inside the auxiliary plate 21, providing rotational power to the auxiliary plate 21. When the auxiliary plate 21 rotates, it drives the lower bevel gear 20 to rotate. The bevel gear 20 meshes with the left-side bevel gear 19, which in turn drives the auger 22 fixed to the left side of the bevel gear 19 to rotate. The auger 22 transports the chemicals from the tank 11 to the internal discharge port, achieving uniform mixing of chemicals and wastewater. Furthermore, it can precisely and consistently add powdered chemicals according to the rotation speed of the stirring blade 13, ensuring sufficient contact and reaction between wastewater and chemicals, thus improving wastewater treatment efficiency and purification effect.
[0028] When the medicine container 11 needs cleaning, press the actuating plate 8. The rotating rod 10 will move downwards. Because the sleeve 17 has a fixed ball 25 inside, and the inner wall of the rotating rod 10 has a special structure, the rotating rod 10 will hit the fixed ball 25 during its downward movement. Since the fixed ball 25 is fixed, the rotating rod 10 will rotate during its downward movement, simultaneously driving the scraper 15 fixed on the lower side to rotate, cleaning the adhering substances on the inner wall of the medicine container 11. The baffle 18 fixed on the upper side of the rotating rod 10, in conjunction with the spring 16 inside the sleeve 17, compresses the spring 16 during the pressing process. After releasing, the spring 16 returns to its original deformation, and the device will rotate upwards along the original path, completing the cleaning operation and resetting.
[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
