Technical Field

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

[0002] Currently, in air conditioning water systems, various chemicals such as rust inhibitors and scale inhibitors are typically added periodically to ensure the water flow in cooling towers or heat exchangers remains clean. The effective use of these chemicals plays a crucial role in extending the service life of the equipment.

[0003] In existing technologies, chemical agents are added and then mixed using a stirring structure to achieve water treatment for air conditioning. However, existing stirring structures are relatively simple, resulting in poor stirring effect and low stirring efficiency. Manually adding agents is inefficient and the dosage is not accurate. Furthermore, some agent adding devices are fixed on the mixing tank, making maintenance inconvenient. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing air conditioning water treatment systems have poor stirring effects and the dosing device is not easy to disassemble and maintain.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A dosing device for air conditioning water treatment includes a housing, a plurality of support legs fixedly connected to the lower end of the housing, an inlet pipe fixedly connected to one side of the housing and communicating with it, the inlet pipe being connected to a water supply pipe, an outlet pipe fixedly connected to the lower end of the housing and communicating with it, a first control valve and a second control valve respectively connected to the inlet pipe and the outlet pipe, and further includes a stirring mechanism and a dosing mechanism, both of which are connected to the housing;

[0007] The dosing mechanism includes a storage tank, a metering pump, and a locking assembly. The storage tank is installed on the upper part of the tank body via the locking assembly, and the metering pump is fixed to the upper part of the tank body to control the quantitative input of the drug from the storage tank into the tank body.

[0008] The stirring mechanism includes a motor, which is fixed to the upper end of the housing. A connecting shaft is fixed to the output end of the motor. The lower end of the connecting shaft is rotatably connected to the bottom of the inner wall of the housing. A spiral stirring plate, stirring fan blades, and a scraper are connected sequentially from top to bottom on the connecting shaft. The stirring and mixing of water and medicine in the housing is achieved by driving the motor.

[0009] Furthermore, a slide rail is fixedly connected to the upper end of the tank, and the slide rail is designed as an inverted trapezoidal linear slide rail. A mounting base is fixedly connected to the lower end of the liquid storage tank. The mounting base has a groove at its lower end that passes through only one side of the mounting base. The mounting base is slidably adapted to the slide rail through the groove.

[0010] Furthermore, the locking assembly includes a slide rod, a spring, and a latching plate. A first mounting block and a second mounting block are fixedly connected to the upper end of the housing. The slide rod is fixed between the first mounting block and the second mounting block. One end of the latching plate is slidably connected to the slide rod. The spring is sleeved on the slide rod, and the two ends of the spring are respectively fixed to the second mounting block and the latching plate. The latching plate is L-shaped and slides at the upper end of the housing to limit the position of the mounting seat.

[0011] Furthermore, a T-shaped limiting block is fixed to the bottom surface of one end of the buckle plate, and a limiting groove is provided at the upper end of the box body, in which the limiting block slides adaptably.

[0013] Furthermore, the stirring fan blades are provided with several through holes, and the stirring fan blades are fixed to the connecting shaft in a ring array. The scraper frame is designed with a U-shaped structure and is symmetrically fixed to the connecting shaft. Only the lower end of the scraper frame slides against the bottom surface of the inner wall of the box. The lower end of the scraper frame is provided with a ceramic wear-resistant strip.

[0014] Furthermore, the inlet pipe and the outlet pipe are connected by a flange and a filter screen is clamped and fixed between them.

Detailed Implementation

[0026] like Figure 1-6 As shown, an air conditioning water treatment dosing device includes a housing 1. Several support legs 101 are fixedly connected to the lower end of the housing 1. An inlet pipe 102 connected to and communicating with the housing 1 is fixedly connected to one side of the housing 1. The inlet pipe 102 is connected to a water supply pipe 2. The inlet pipe 102 and the water supply pipe 2 are connected by a flange and a filter screen 104 is clamped and fixed between them to perform preliminary filtration of the input air conditioning water. An outlet pipe 105 connected to and communicating with the housing 1 is fixedly connected to the lower end of the housing 1. A first control valve 103 and a second control valve 106 are respectively connected to the inlet pipe 102 and the outlet pipe 105. The device also includes a stirring mechanism 4 and a dosing mechanism 3. Both the stirring mechanism 4 and the dosing mechanism 3 are connected to the housing 1. Chemical agents are added to the housing 1 through the dosing mechanism 3. The air conditioning water is introduced into the housing 1 through the water supply pipe 2 and the inlet pipe 102. Then, the stirring mechanism 4 is used to mix the chemical agents and the air conditioning water evenly. The mixed water is discharged from the outlet pipe 105.

[0027] It is worth noting that the various sensors (such as temperature sensors, pH sensors, liquid level sensors, etc.) in the tank 1 (with coating) used for mixing air conditioning water and chemical agents are all existing and common technologies, and the controller for controlling the electronic components such as sensors is also existing technology, which will not be described in detail.

[0028] Example 1:

[0029] like Figure 3, 5 As shown in Figure 6, the dosing mechanism 3 includes a storage tank 301, a metering pump 306, and a locking assembly 5. The storage tank 301 is installed on the upper end of the housing 1 via the locking assembly 5. The metering pump 306 is fixed to the upper end of the housing 1 and is used to control the quantitative input of the drug from the storage tank 301 into the housing 1. A slide rail 108 is fixed to the upper end of the housing 1. The slide rail 108 is an inverted trapezoidal linear slide rail 108. A mounting base 302 is fixed to the lower end of the storage tank 301. The lower end of the mounting base 302 is provided with... A sliding groove 303 extends only through one side of the mounting base 302. The mounting base 302 is slidably connected to the slide rail 108 via the sliding groove 303. The locking assembly 5 includes a sliding rod 503, a spring 504, and a latching plate 505. A first mounting block 501 and a second mounting block 502 are fixedly connected to the upper end of the housing 1. The first mounting block 501 and the second mounting block 502 are not on the moving trajectory of the liquid storage tank 301. The sliding rod 503 is fixedly connected to the first mounting block 501 and the second mounting block 502. Between points 2 and 3, one end of the buckle plate 505 is slidably connected to the slide rod 503. The spring 504 is sleeved on the slide rod 503, and the two ends of the spring 504 are respectively fixed to the second mounting block 502 and the buckle plate 505. The buckle plate 505 is L-shaped and slides on the upper end of the housing 1 to limit the mounting base 302. A T-shaped limiting block 506 is fixed to the bottom surface of one end of the buckle plate 505. The upper end of the housing 1 is provided with a limiting groove 107, and the limiting block 506 slides within the limiting groove 107. The limiting block 506 slides within the limiting groove 107, causing the buckle plate 505 to slide linearly and stably on the housing 1. The liquid storage tank 301 is connected to the slide rail 108 via the mounting base 302 at its lower end. One end of the slide rail 108 abuts against the inner wall of the slide groove 303 without penetrating the outer side of the mounting base 302, and at this time, the other end of the slide rail 108 does not extend out of the outer side of the mounting base 302. Then, the buckle plate 505 is pressed against the outer side of the mounting base 302 by the action of the spring 504 to achieve limiting, thus completing the installation.

[0030] It is worth noting that the liquid storage tank 301 is modularly designed, and multiple liquid storage tanks 301 can store multiple portions of chemical reagents for backup. When the chemical reagents in the tank 1 are insufficient, they can be directly disassembled and replaced.

[0031] Example 2:

[0032] like Figure 4As shown, the stirring mechanism 4 includes a motor 401, which drives the mixing of water and medicine in the tank 1. The metering pump 306 is equipped with an inlet pipe 308 and an outlet pipe 307. The inlet pipe 308 is connected to a delivery pipe 309 via a flange. One end of the delivery pipe 309 is connected to and enters the bottom of the storage tank 301. The upper end of the tank 1 is provided with an inlet 109. The outlet pipe 307 is connected to the upper end of the tank 1 via a flange and is connected to the inlet 109. The upper end of the storage tank 301 is provided with a filling pipe 304, and a connecting cap 305 is threaded onto the filling pipe 304. The motor 401 is fixed to the upper end of the tank 1. The output end of the motor 401 is fixed to a connecting shaft 402. The lower end of the connecting shaft 402 is rotatably connected to the bottom of the inner wall of the tank 1. From top to bottom, a spiral stirring plate 403, stirring blades 404, and a scraper frame 406 are connected sequentially. The stirring blades 404 have several through holes 405, which are used to create local turbulence and promote the mixing of the chemicals. The stirring blades 404 are fixed to the connecting shaft 402 in a ring array. The scraper frame 406 is designed with a U-shaped structure and is symmetrically fixed to the connecting shaft 402. Only the lower end of the scraper frame 406 slides against the bottom surface of the inner wall of the housing 1. The lower end of the scraper frame 406 is provided with a ceramic wear-resistant strip. Driven by the motor 401, the spiral stirring plate 403, stirring blades 404, and scraper frame 406 all provide different vortex trends, thereby effectively improving the mixing effect and mixing efficiency of the chemical agents and the air conditioning water. The scraper frame 406 can also prevent sediment from accumulating on the ground of the housing 1.

[0033] It is worth noting that the sealing between the connecting shaft 402 and the housing 1 can be achieved by existing technology (such as double mechanical seal). The specific sealing method is selected according to the actual use. The specific model, power and speed of the motor are also selected according to the actual use, and will not be elaborated here.

[0034] In use, this utility model introduces air conditioning water into the housing 1 through the water supply pipe 2 and the water inlet pipe 102. The metering pump 306 controls the liquid supply pipe 309 to draw chemical agents from the liquid storage tank 301. Then, the liquid outlet pipe 307 introduces the chemical agents into the housing 1 through the liquid inlet 109. The output end of the motor 401 drives the connecting shaft 402 to rotate, thereby driving the spiral stirring plate 403, stirring fan blades 404 and scraper 406 to rotate, so that the chemical agents and air conditioning water are evenly mixed. The mixed water can be discharged for use by opening the water outlet pipe 105 through the second control valve 106.

[0035] When the liquid storage tank 301 needs to be replaced and cleaned, pull the buckle plate 505 so that one end slides on the slide rod 503 to compress the spring 504. At the same time, the limit block 506 slides in the limit groove 107 to improve the stability of the buckle plate 505. After the buckle plate 505 slides out of the sliding track of the mounting base 302 on the base, the liquid storage tank 301 can be pulled to remove it and the new liquid storage tank 301 can be installed on the guide rail through the mounting base 302. After releasing the buckle plate 505, the buckle plate 505 slides and fits against the outside of the mounting base 302 under the action of the spring 504, thus completing the removal and replacement of the liquid storage tank 301.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
