Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a precision dosing device. Background Technology
[0002] With the acceleration of urbanization and the continuous expansion of industrial production, the amount of wastewater generated is increasing daily. If wastewater is discharged directly without effective treatment, it will cause serious damage to natural water bodies, soil, and the ecological environment, affecting human health and ecological balance. Therefore, treating wastewater before discharge is of paramount importance. Chemical dosing equipment is a key component of wastewater treatment systems, mainly used to precisely add various chemical agents to wastewater, such as coagulants, flocculants, disinfectants, and pH adjusters, to improve wastewater quality, promote the removal and separation of pollutants, and ensure that the treated wastewater meets discharge standards or achieves reuse requirements.
[0003] The patent announcement number CN219079121U discloses a precision dosing mechanism for wastewater treatment equipment. This precision dosing mechanism for wastewater treatment equipment, by setting up a mounting plate, a rotating gear ring, a precision dosing structure and a conveying pipeline, allows the rotating gear ring to cooperate with a drive motor and transmission gears to accurately and evenly add the agent to a designated position in the wastewater, and can also quickly mix the agent with the wastewater, ultimately improving the efficiency of wastewater treatment.
[0004] Although the drive motor of the aforementioned precision dosing mechanism drives the rotating gear ring and precision dosing structure to rotate around the mounting plate via transmission gears, and the reagent flows out from the dosing holes on the precision dosing structure to be precisely and evenly added to the designated location of the wastewater, there are still some shortcomings that warrant further optimization and improvement. For example, the precision dosing structure can only move in a circular motion around the mounting plate, and cannot achieve full coverage of the wastewater treatment equipment. This means that in some cases, it may not be possible to perform precise dosing at any designated location on the wastewater treatment equipment, limiting the application flexibility and treatment effect of the dosing mechanism.
[0005] Therefore, it is necessary to invent a precision dosing device to solve the above problems. Utility Model Content

[0009] Preferably, each of the two longitudinal guide rails is internally connected to a set of rollers, and the two sets of rollers are respectively installed at the bottom of both ends of the transverse load-bearing beam.
[0010] Rollers are rolled inside the longitudinal guide rail and installed at the bottom of both ends of the transverse load-bearing beam, which reduces the frictional resistance when the transverse load-bearing beam moves and improves the smoothness and efficiency of movement.
[0011] Preferably, the dosing mechanism includes a suspension bracket, which is fixedly connected to the bottom of the slide of the transverse linear module. A rotary joint is installed in the middle of the suspension bracket, and a dosing tube is rotatably connected to the bottom output end of the rotary joint.
[0012] The dosing mechanism includes a suspension bracket, a rotary joint, and a dosing rod. This design allows the dosing rod to rotate under the drive of a second motor, which helps to ensure uniform dosing of the chemicals.
[0013] Preferably, a No. 2 motor is installed on one side of the suspension bracket, and a No. 3 gear is fixedly connected to one end of the output shaft of the No. 2 motor. A No. 3 gear is also fixedly connected to the surface of the dosing tube near its top input end, and the two No. 3 gears are meshed together.
[0014] The active rotation of the dosing rod is achieved through the transmission connection of motor No. 2 and gear No. 3.
[0015] Preferably, the surface of the dosing tube is provided with a discharge hole, and a lightweight slurry plate is fixedly connected to the surface of the dosing tube.
[0016] The surface of the dosing tube has discharge holes and is fixedly connected to a lightweight slurry plate. The design of the discharge holes allows the agent to be discharged into the wastewater evenly and continuously, while the lightweight slurry plate can stir the wastewater when the dosing tube rotates, accelerating the mixing of the agent and the wastewater and improving the treatment effect.
[0017] Preferably, a metering pump is installed on the top of the transverse bearing beam, and the No. 1 motor, the No. 2 motor, and the metering pump are all electrically connected to the controller.

During the dosing process, the dosing tube is driven to rotate by a No. 2 motor. This not only helps to discharge the agent evenly, but also stirs the sewage through the lightweight slurry plate, promoting the rapid mixing of the agent and the sewage. This design effectively shortens the mixing time of the agent and the sewage and improves the sewage treatment efficiency. Attached Figure Description

The two ends of the transverse support beam 3 pass through the two grooves 7 and extend into the two longitudinal guide rails 2. The two ball screws 6 pass through the transverse support beam 3. The beam 3 is connected to the transverse load-bearing beam 3 at both ends. One end of the ball screw 6 extends to the outside of the longitudinal guide rail 2 and is fixedly connected to a first gear 8 and a second gear 9. A first motor 10 and a controller 11 are mounted on the surface of the loading bracket 1. One end of the output shaft of the first motor 10 is also fixedly connected to a first gear 8. The two first gears 8 are connected by a first internal gear belt 12. The other ball screw 6 extends to the outside of the longitudinal guide rail 2 and is also fixedly connected to a second gear 9. The two second gears 9 are connected by a second internal gear belt 13.
[0034] In one aspect of this embodiment, each of the two longitudinal guide rails 2 has a set of rollers 14 rollingly connected inside. The two sets of rollers 14 are respectively installed at the bottom of both ends of the transverse bearing beam 3. The dosing mechanism 5 includes a suspension bracket 15, which is fixedly connected to the bottom of the slide of the transverse linear module 4. A rotary joint 16 is installed in the middle of the suspension bracket 15. A dosing tube 17 is rotatably connected to the bottom output end of the rotary joint 16. A second motor 18 is installed on one side of the suspension bracket 15. A third gear 19 is fixedly connected to one end of the output shaft of the second motor 18. The surface of the dosing tube 17 is close to... A No. 3 gear 19 is also fixedly connected at the top input end. The two No. 3 gears 19 are meshed together. A discharge hole 20 is opened on the surface of the dosing tube rod 17. A lightweight slurry plate 21 is fixedly connected to the surface of the dosing tube rod 17. A metering pump 22 is installed on the top of the transverse bearing beam 3. The No. 1 motor 10, the No. 2 motor 18 and the metering pump 22 are all electrically connected to the controller 11. A pump inlet hose 23 is installed at the input end of the metering pump 22. A pump outlet hose 24 is installed at the output end of the metering pump 22.

[0036] Working principle of this utility model:
[0037] Refer to the instruction manual appendix Figure 1-6When using this utility model, firstly, the loading bracket 1 is securely installed on the top of the sewage treatment equipment, and the input end of the pumping hose 23 of the metering pump 22 is inserted into the inside of the reagent storage tank.
[0038] The controller 11 starts the first motor 10. The output shaft of the first motor 10 drives the first gear 8, which is fixedly connected to one end, to rotate. The first gear 8 drives another first gear 8 and its corresponding ball screw 6 to rotate through the first internal gear belt 12. At the same time, the ball screw 6 rotates through the second gear 9 and the second internal gear belt 13 to drive the other ball screw 6 to rotate together, ensuring that the two ball screws 6 rotate synchronously, so that the transverse bearing beam 3 can move smoothly along the longitudinal guide rail 2.
[0039] A transverse linear module 4 is installed on the transverse bearing beam 3. The slide of the transverse linear module 4 is controlled by the controller 11 to move laterally along the transverse bearing beam 3. The movement of the slide drives the dosing mechanism 5, which is fixedly connected to its bottom, to move laterally, thereby realizing the movement of the dosing mechanism 5 at any position in the two-dimensional plane above the sewage treatment equipment.
[0040] When the dosing unit 5 moves to the designated position, the metering pump 22 is started by the controller 11. The metering pump 22 draws the agent from the inside of the agent storage tank through the pump in hose 23 and delivers the agent to the top input end of the rotary joint 16 through the pump out hose 24. The agent enters the dosing tube 17 through the rotary joint 16 and is evenly discharged into the sewage through the discharge hole 20 opened on the surface of the dosing tube 17.
[0041] During the dosing process, the controller 11 starts the second motor 18, which drives the third gear 19 to rotate, thereby driving the dosing tube rod 17 to rotate. The rotation of the dosing tube rod 17 not only helps to evenly discharge the agent, but also stirs the sewage through the lightweight slurry plate 21 fixedly connected to its surface, promoting the mixing of the agent and the sewage and improving the sewage treatment efficiency.
[0042] The entire dosing process is automated through controller 11. Controller 11 precisely controls the operation of motor 10, horizontal linear module 4, motor 18 and metering pump 22 according to the preset dosing program to achieve precise dosing.
