Description

Technical Field

[0001] This utility model relates to the field of central air conditioning circulating water processor technology, and in particular to a central air conditioning circulating water processor with automatic dosing control. Background Technology

[0002] During the operation of a central air conditioning system, the circulating water system (including the cooling water system and the chilled water system) is prone to heat exchange efficiency reduction, pipe blockage, and even equipment damage due to water quality problems (such as scaling, corrosion, and microbial growth). Therefore, it is necessary to use a central air conditioning circulating water processor to treat the circulating water regularly.

[0003] Existing central air conditioning circulating water processors require the addition of chemicals to the circulating water during the treatment process. However, the current method of adding chemicals is mostly manual, which leads to large deviations in the dosage. Therefore, a central air conditioning circulating water processor with automatic chemical dosing control is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic dosing and control system for central air conditioning circulating water.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic dosing control central air conditioning circulating water processor, comprising a treatment tank, a feeding pipe installed inside the treatment tank, a first one-way valve installed at the end of the feeding pipe near the treatment tank, a first sliding groove opened inside the feeding pipe, a piston rod slidably connected inside the first sliding groove, a sealing ring installed inside the feeding pipe, and the end of the piston rod away from the piston being movably connected to the inside of the sealing ring, an installation groove opened at the top of the feeding pipe, a second one-way valve installed inside the installation groove, a dosing pipe installed at the top of the feeding pipe, a control valve installed inside the dosing pipe, an output end of a chemical tank fixedly connected at the end of the dosing pipe away from the feeding pipe, and a tank cover installed at the top of the chemical tank, a support frame fixedly connected to the circumference of the treatment tank, and the chemical tank located at the top of the support frame; A fixing plate is fixedly connected to the end of the piston rod, and a connecting rod is fixedly connected to the side surface of the fixing plate. A limit ring is fixedly connected to the end of the connecting rod away from the fixing plate. A T-shaped limit post is movably connected inside the limit ring. A turntable is eccentrically connected to the bottom of the T-shaped limit post. A second rotating post is fixedly connected to the bottom of the turntable. The output end of a second motor is fixedly connected to the bottom of the second rotating post.

[0006] Furthermore: a fixed frame is fixedly connected to the circumferential surface of the processing tank, and the second rotating column passes through the fixed frame and is rotatably connected to the inside of the fixed frame.

[0007] Furthermore: a limiting frame is fixedly connected to the bottom of the fixed frame, and the second motor is located inside the limiting frame.

[0008] Furthermore, the top of the fixing frame is provided with a second sliding groove, and the bottom of the fixing plate is slidably connected to the inside of the second sliding groove.

[0009] Furthermore, the treatment tank is equipped with an inlet pipe and an outlet pipe, with the inlet pipe located below the outlet pipe, and a drain pipe is provided at the bottom of the treatment tank.

[0010] Furthermore: a first motor is fixedly connected to the top of the processing tank, a first rotating column is fixedly connected to the output end of the first motor, and a stirring column is fixedly connected to the circumferential surface of the first rotating column.

[0011] This utility model has the following beneficial effects: Compared with existing technologies, this automatic dosing control central air conditioning circulating water processor, through the installation of a first one-way valve, a second one-way valve, a limit ring, and a T-shaped limit post, operates by activating a second motor. The second rotating column drives a turntable to rotate, which in turn drives the limit ring to reciprocate the connecting rod via the T-shaped limit post. This, in turn, drives a piston rod to reciprocate and reposition within the feeding pipe via a fixed plate. When the piston rod moves towards the second motor, the first one-way valve closes and the second one-way valve opens, drawing the chemical from the feeding pipe. When the piston rod moves from the end closest to the second motor towards the treatment tank, the second one-way valve closes and the first one-way valve opens, pushing the drawn-in chemical into the treatment tank. This completes the dosing operation. Furthermore, the distance the piston rod displaces during each rotation of the turntable is consistent, ensuring that the dosage of chemical drawn in each cycle is approximately the same, thus improving the convenience of chemical dosing.

[0012] Compared with existing technologies, this automatic dosing and control system for central air conditioning circulating water processor, by setting up a first motor, a first rotating column, and a stirring column, allows the cleaning agent to be delivered into the treatment tank through a chemical dosing device during use. The first motor is started, and the first rotating column drives the stirring column to stir the agent inside the treatment tank, thereby fully mixing it with the circulating water, which helps to improve the efficiency of circulating water treatment.

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.

[0016] Reference Figure 1-4 The present invention provides an automatic dosing control central air conditioning circulating water processor: including a treatment tank 1, a feeding pipe 11 installed inside the treatment tank 1, a first one-way valve 13 installed at one end of the feeding pipe 11 near the treatment tank 1, a first sliding groove 12 opened inside the feeding pipe 11, a piston rod 15 slidably connected inside the first sliding groove 12, a sealing ring 14 installed inside the feeding pipe 11, and the end of the piston rod 15 away from the piston being movably connected to the inside of the sealing ring 14, an installation groove 16 opened at the top of the feeding pipe 11, a second one-way valve 17 installed inside the installation groove 16, a dosing pipe 18 installed at the top of the feeding pipe 11, a control valve 29 installed inside the dosing pipe 18, an output end of a chemical tank 9 fixedly connected at one end of the dosing pipe 18 away from the feeding pipe 11, and a tank cover 10 installed at the top of the chemical tank 9; a support frame 8 fixedly connected to the circumferential surface of the treatment tank 1, and the chemical tank 9 located at the top of the support frame 8; A fixing plate 27 is fixedly connected to the end of the piston rod 15. A connecting rod 26 is fixedly connected to the side surface of the fixing plate 27. A limit ring 25 is fixedly connected to the end of the connecting rod 26 away from the fixing plate 27. A T-shaped limit post 24 is movably connected inside the limit ring 25. A turntable 23 is eccentrically connected to the bottom of the T-shaped limit post 24. A second rotating post 22 is fixedly connected to the bottom of the turntable 23. The output end of the second motor 21 is fixedly connected to the bottom of the second rotating post 22. When the device is in use, the second motor 21 is started, and the second rotating column 22 drives the turntable 23 to rotate. The T-shaped limiting column 24 drives the limiting ring 25 to reciprocate and push the connecting rod 26. Then, the fixed plate 27 drives the piston rod 15 to reciprocate and move at a fixed point inside the feeding pipe 11. When the piston rod 15 moves towards the second motor 21, the first one-way valve 13 closes and the second one-way valve 17 opens, thereby drawing the medicine from the feeding pipe 18 into the feeding pipe 11. When the piston rod 15 moves from the end closest to the second motor 21 towards the treatment tank 1, the second one-way valve 17 closes and the first one-way valve 13 opens, thereby pushing the drawn medicine into the treatment tank 1, thus realizing the medicine addition operation. The distance that the piston rod 15 moves by rotating the turntable 23 one revolution is the same, thereby ensuring that the dosage of medicine drawn in each time is approximately the same, which helps to improve the convenience of medicine addition.

[0017] A fixing frame 19 is fixedly connected to the circumferential surface of the treatment tank 1. The second rotating column 22 passes through the fixing frame 19 and is rotatably connected to the inside of the fixing frame 19. The fixing frame 19 is used to limit the installation of the second rotating column 22.

[0018] A limiting frame 20 is fixedly connected to the bottom of the fixing frame 19, and the second motor 21 is located inside the limiting frame 20. The limiting frame 20 is used to limit the installation of the second motor 21.

[0019] The top of the fixing frame 19 is provided with a second sliding groove 28, and the bottom of the fixing plate 27 is slidably connected to the inside of the second sliding groove 28. The second sliding groove 28 is used to limit the displacement path of the fixing plate 27.

[0020] The treatment tank 1 is equipped with an inlet pipe 2 and an outlet pipe 3. The inlet pipe 2 is located below the outlet pipe 3, and a drain pipe 7 is installed at the bottom of the treatment tank 1. Circulating water is injected into the treatment tank 1 through the inlet pipe 2, and after being mixed with the reagent, it is discharged from the outlet pipe 3. Impurities inside the treatment tank 1 can be discharged from the drain pipe 7.

[0021] A first motor 4 is fixedly connected to the top of the treatment tank 1. A first rotating column 5 is fixedly connected to the output end of the first motor 4. A stirring column 6 is fixedly connected to the circumference of the first rotating column 5. When the device is in use, the cleaning agent is fed into the treatment tank 1 using the agent addition device. The first motor 4 is started, and the first rotating column 5 drives the stirring column 6 to stir the agent inside the treatment tank 1, thereby fully mixing it with the circulating water and improving the efficiency of circulating water treatment.

[0022] Working principle: When the device is in use, the second motor 21 is started, and the second rotating column 22 drives the turntable 23 to rotate. This, in turn, uses the T-shaped limiting column 24 to drive the limiting ring 25 to reciprocate the connecting rod 26. This, in turn, drives the piston rod 15 to reciprocate and move at a fixed point inside the feeding pipe 11 via the fixing plate 27. When the piston rod 15 moves towards the second motor 21, the first one-way valve 13 closes and the second one-way valve 17 opens, thus drawing the agent from the dosing pipe 18 into the feeding pipe 11. When the piston rod 15 moves from the position closest to the second motor 21... When the end moves towards the treatment tank 1, the second one-way valve 17 closes and the first one-way valve 13 opens, thereby pushing the inhaled agent into the treatment tank 1 to realize the dosing operation. Moreover, the piston rod 15 is displaced by the same distance during each rotation of the turntable 23, thus ensuring that the dosage of the inhaled agent is approximately the same each time, which helps to improve the convenience of agent addition. After the agent is added, the first motor 4 is started and the first rotating column 5 drives the stirring column 6 to stir the agent inside the treatment tank 1, thereby fully mixing it with the circulating water, which helps to improve the efficiency of circulating water treatment.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
