Description

Technical Field

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

[0002] Chemical dosing in urban wastewater treatment refers to the addition of various chemical agents during the wastewater treatment process to accelerate the purification process and improve treatment efficiency. These agents include flocculants, coagulants, conditioning agents, demulsifiers, defoamers, pH adjusters, redox agents, and disinfectants.

[0003] Currently, in the wastewater treatment process, some dosing units directly sprinkle chemicals on the surface of the treatment tank, which causes the chemicals to take a long time to sink into the water. During the sinking process, the chemicals gradually dissolve, resulting in less chemicals falling to the bottom of the wastewater. This prevents the chemicals from mixing fully with the wastewater, thereby reducing the effectiveness of wastewater treatment.

[0004] For example, a wastewater treatment dosing mechanism disclosed in the prior art (CN219526298U) includes a purification tank. A pair of fixed columns are fixedly mounted on the upper surface of the purification tank, and each column has a sliding block inside. A dispensing box is fixedly mounted on the upper end of each sliding block. Although this device can evenly distribute the chemicals on the wastewater surface, it still suffers from the aforementioned problems. Therefore, an improvement is proposed. Utility Model Content

[0005] This invention is a drug dosing device proposed to overcome the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dosing device, including a treatment tank, a transverse moving component installed on the top of the treatment tank, two main pipes symmetrically rotatably connected to the movable end of the transverse moving component, multiple short pipes fixedly penetrating the outer surface of the two main pipes, and multiple water distribution holes penetrating into the interior opened on the outer surface of the multiple short pipes.

[0007] Both of the aforementioned main pipes are connected to the processing pool by an auxiliary transmission assembly.

[0008] Both of the main pipes have a rotary joint fixedly connected to their tops, and the movable ends of the two rotary joints are jointly fixedly connected to a shunt pipe.

[0009] The movable end of the transverse component is fixedly connected to a housing, and a water tank is fixedly installed on one inner wall of the housing. A drug supply component is installed between the water tank and the housing.

[0010] The casing houses an effluent sewage pump body and an influent sewage pump body. A dual-shaft motor is also fixedly installed inside the casing, with its two drive shafts respectively fixedly connected to the input shafts of the adjacent effluent sewage pump body and influent sewage pump body.

The drive end of the single-axis motor is fixedly connected to a screw, which is rotatably connected to the treatment tank. A slide is threaded onto the outer surface of the screw, and the slide is fixedly connected to the housing. The main pipe is rotatably connected to the slide. The screw and the single-axis motor cooperate to drive the slide to move.

[0012] Furthermore, the bottom of the slide is slidably connected to a guide rail, and the guide rail is fixedly installed on the top of the treatment tank. The guide rail has a limiting effect on the slide, which can ensure the stability of its movement.

[0013] Furthermore, both of the auxiliary transmission components include racks, which are fixedly mounted on the inner wall of one side of the treatment tank. A driven gear is meshed with one side of the outer surface of the rack, and the mounting shaft of the driven gear passes through the slide and is rotatably connected to it. When the driven gear moves along the rack, the driven gear will rotate.

[0014] Furthermore, an auxiliary gear is fixedly connected to the top of the mounting shaft of the driven gear, and a ring gear is meshed with one side of the outer surface of the auxiliary gear, and the ring gear is fixedly sleeved on the outer surface of the main tube.

[0015] Furthermore, the agent supply assembly includes a support base, which is fixedly connected to the housing. A micro auger conveyor is fixedly embedded on one side of the top of the support base, and the output end of the micro auger conveyor extends into the interior of the water tank. The micro auger conveyor facilitates continuous delivery of the agent.

[0016] Furthermore, a chemical tank is fixedly connected to the feed end of the micro auger conveyor, and the chemical tank is used to store sewage treatment chemicals.

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

Multiple water distribution holes 17 extending into the interior are opened on the outer surface of each of the multiple short pipes 4. The transverse moving assembly includes a single-axis motor 8, which is fixedly installed on one side of the outer surface of the treatment tank 1. A screw 3 is fixedly connected to the drive end of the single-axis motor 8, and the screw 3 is rotatably connected to the treatment tank 1. The outer surface of the rotatable connection of the screw 3 rotates symmetrically. The connection has two bearing seats, which are fixedly connected to the treatment tank 1. The outer surface of the screw 3 is threaded with a slide 7, which is fixedly connected to the housing 5. The main pipe 18 is rotatably connected to the slide 7. The main pipe 18 and the slide 7 are connected by a bearing. The inner ring of the bearing is fixedly connected to the main pipe 18, and the outer ring of the bearing is fixedly connected to the slide 7. The bearing provides support for the main pipe 18, which is beneficial for the installation of the main pipe 18 and also reduces the rotational resistance of the main pipe 18. The bottom of the slide 7 is slidably connected to a guide rail 9, which is fixedly installed on the top of the treatment tank 1.

[0027] Both main pipes 18 are connected to the treatment tank 1 by auxiliary transmission components. Each auxiliary transmission component includes a rack 2, which is fixedly mounted on the inner wall of one side of the treatment tank 1. A driven gear 16 is meshed on one side of the outer surface of the rack 2. The mounting shaft of the driven gear 16 passes through the slide 7 and is rotatably connected to it. The mounting shaft of the driven gear 16 is connected to the slide 7 by a bearing. The inner ring of the bearing is fixedly connected to the mounting shaft of the driven gear 16, and the outer ring of the bearing is fixedly connected to the slide 7. The bearing provides support for the driven gear 16, which is beneficial for its installation. An auxiliary gear 15 is fixedly connected to the top of the mounting shaft of the driven gear 16. A ring gear 24 is meshed on one side of the outer surface of the auxiliary gear 15 and is fixedly sleeved on the outer surface of the main pipe 18. When the slide 7 moves, it will drive the driven gear 16 to move. The driven gear 16 rotates under the action of the rack 2, and then drives the main pipe 18 to rotate through the cooperation of the auxiliary gear 15 and the ring gear 24.

[0028] Rotary joints 14 are fixedly connected to the top of both main pipes 18, and the movable ends of the two rotary joints 14 are fixedly connected to the branch pipes 23.

[0029] The movable end of the transverse component is fixedly connected to the housing 5. A water tank 10 is fixedly installed on one inner wall of the housing 5. A medicine supply component is installed between the water tank 10 and the housing 5. The medicine supply component includes a support base 12, which is fixedly connected to the housing 5.

The micro auger conveyor 11 is existing technology, and its model and specifications are selected according to actual needs. A medicine tank 6 is fixedly connected to the feed end of the micro auger conveyor 11. The medicine tank 6 temporarily stores the medicine, and its size can be designed according to actual needs.

[0030] The casing 5 houses the effluent sewage pump body 13 and the influent sewage pump body 21. A dual-shaft motor 20 is also fixedly installed inside the casing 5. The two drive shafts of the dual-shaft motor 20 are fixedly connected to the input shafts of the adjacent effluent sewage pump body 13 and influent sewage pump body 21, respectively. The outlet end of the effluent sewage pump body 13 is fixedly connected to the diversion pipe 23, and the influent end of the effluent sewage pump body 13 is fixedly connected to the water tank 10. The outlet end of the influent sewage pump body 21 is fixedly connected to the water tank 10 via a fixed pipe 19. The influent end of the influent sewage pump body 21 is fixedly connected to an influent pipe 22. The sewage pump body is based on existing technology, and its model and specifications are selected according to actual needs. A filter screen can be installed at the bottom of the influent pipe 22 to prevent larger impurities in the sewage from entering the water tank 10.

[0031] Working principle: When chemicals need to be added, the dual-shaft motor 20 starts first, driving the effluent sewage pump body 13 and the influent sewage pump body 21 (the water tank 10 temporarily stores a set amount of water). The influent sewage pump body 21 sends sewage to the water tank 10 through the inlet pipe 22 and the fixed pipe 19. Then, the effluent sewage pump body 13 transports the water in the water tank 10 to the main pipe 18 through the diversion pipe 23 and the rotary joint 14, and then discharges it through the short pipe 4 and the water distribution hole 17. Then, the micro auger conveyor 11 runs, and the micro auger conveys... Machine 11 transports the chemicals from the chemical tank 6 to the water tank 10, and then, along with the output wastewater, into the treatment pool 1. Next, the single-shaft motor 8 runs, driving the screw 3 to rotate. The screw 3 drives the slide 7 to move along the guide rail 9. The slide 7 drives the driven gear 16 and other components mounted on the slide 7 to move. The driven gear 16 rotates under the action of the rack 2. The driven gear 16 drives the ring gear 24 to rotate through the auxiliary gear 15. The ring gear 24 drives the main pipe 18 and the short pipe 4 to rotate, evenly delivering the chemicals into the treatment pool 1.

[0032] It should be noted that, in actual use, an existing controller can be added. The controller is electrically connected to the single-axis motor 8, the dual-axis motor 20, and the micro-auger conveyor 11 to facilitate overall control. The specific data analysis and processing involved in further realizing the control function are methods that can be implemented by those skilled in the art based on common knowledge, and these methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that this hardware structure improvement can achieve, based on common knowledge.
