Description

Technical Field

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

[0002] A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners, this system centrally processes air to achieve comfort requirements. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity to offset the heat load of the indoor environment. When the central air conditioning unit is running, the circulating water circulates from the refrigeration unit, circulating pipes, and cooling tower. In order to prevent the circulating water quality from exceeding the standard, the circulating water system needs to be treated with chemicals.

[0003] The utility model with publication number CN222872050U proposes an automatic dosing device for central air conditioning water treatment, including an automatic dosing installation box. The automatic dosing installation box contains a mixing detection moving component. This utility model improves upon existing technologies, solving the problems of existing energy-saving and environmentally friendly central air conditioning water treatment dosing devices, which are inconvenient for automatic dosing inside the central air conditioning system, requiring manual dosing, increasing workload, reducing maintenance efficiency, and hindering cleaning. Furthermore, in practical use, through mixing detection and moving, a single drive source simultaneously achieves the functions of mixing materials, detecting at different locations, and cleaning the inner wall. This solves the problem in existing technologies where there is a certain difference in the concentration of the agent between the upper and lower layers during mixing, resulting in inaccurate detection data and inaccurate agent dosage, thus affecting the purification efficiency of circulating water.

[0004] However, the above-mentioned existing technology still has shortcomings in practical use: a liftable circular plate is set in the tank, and various sensors for detecting water quality are set on the circular plate. The lifting of the circular plate is controlled by a reciprocating screw. Since the operation of the reciprocating screw has high requirements for environmental conditions, and the reciprocating screw in the existing technology runs in water, it is difficult to lubricate the reciprocating screw effectively. Therefore, it is easy to cause the problem of operation jamming and accelerated wear, which has the defect of insufficient practicality.

[0005] Therefore, this utility model provides an air conditioning water treatment dosing device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an air conditioning water treatment dosing device to solve the problems mentioned in the background technology. This utility model has the advantage of extending the service life of the reciprocating screw, and while satisfying the function of fully stirring the liquid in the mixing tank, it also has the advantage of making the internal cleaning more convenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning water treatment dosing device includes a mixing chamber, an annular plate located within the mixing chamber, a detection component, and a reciprocating screw. A portal frame is fixedly mounted on the top of the annular plate, and a vertical shaft near one end is fixedly connected to the top wall of the portal frame. The vertical shaft penetrates the top wall of the mixing chamber and the two slide vertically together. A base plate is fixedly connected to the outer wall of the mixing chamber. The bottom of the lead screw on the reciprocating screw is rotatably connected to the base plate. An arm plate with one end fixedly connected to the top of the vertical shaft is fixedly connected to the outer wall of the lead sleeve on the reciprocating screw. An impeller is disposed inside the annular plate, and the impeller is connected to the annular plate via a connecting plate. The detection component is fixedly mounted on the inner circumferential wall of the annular plate.

[0008] Furthermore, the number of impellers is three, and they are evenly distributed around the circumference of the annular plate.

[0009] Furthermore, one end of the connecting plate is fixedly connected to the top of the annular plate, and the other end of the connecting plate is fixedly connected to a positioning sleeve. The wheel shaft in the middle of the impeller is sleeved in the positioning sleeve and the two are rotatably connected.

[0010] Furthermore, a servo motor is fixedly connected to the bottom of the base plate, and the output shaft of the servo motor is fixedly connected to the bottom of the lead screw.

[0011] Furthermore, a guide shaft is fixedly connected to the middle of the top of the mixing chamber, a guide sleeve is fixedly connected to the middle of the top of the gantry frame and sleeved outside the guide shaft, a guide shaft is fixedly connected to the top wall of the mixing chamber, and a guide sleeve is fixedly connected to the arm plate and sleeved on the guide shaft.

[0012] Furthermore, a mounting platform is fixedly connected to the inner peripheral wall of the annular plate, and the detection assembly includes a pH sensor, an ORP sensor, and a conductivity sensor, which are fixedly mounted on one side of the mounting platform.

[0013] Furthermore, a manhole located above the detection component is fixedly connected to the top of the mixing chamber.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the reciprocating lead screw is set on the outside of the mixing box. The lead sleeve on the reciprocating lead screw is connected to the annular plate inside the mixing box through the vertical shaft. When the lead sleeve moves up and down, it can drive the annular plate inside the mixing box to move up and down, thereby driving the detection component to move up and down for real-time monitoring. This setting of placing the reciprocating lead screw externally will not cause the problem of insufficient lubrication and accelerated wear, and is more practical.

[0016] 2. In this utility model, by setting an impeller inside the annular plate, the up-and-down movement of the annular plate can drive the impeller to move synchronously. The interaction between the impeller and the fluid will adaptively rotate. The up-and-down movement of the impeller, combined with the adaptive rotation, can fully stir the liquid in the mixing box. Thus, when the reciprocating screw operates, it can detect the up-and-down movement of the detection component and stir the liquid at the same time. Compared with the prior art, this setting has the advantages of high transmission efficiency and energy saving.

[0017] 3. In this utility model, a manhole is provided on the top of the mixing chamber above the detection component. Combined with the structural feature of the impeller being installed inside the annular plate, the mixing chamber is in an open state. This arrangement makes it easier for maintenance personnel to use tools through the manhole to clean the inner wall of the mixing chamber and to make the maintenance of the detection component more convenient.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 3This utility model provides a technical solution: an air conditioning water treatment dosing device, including a mixing tank 1, an annular plate 2 located inside the mixing tank 1, a detection component, and a reciprocating screw. Multiple dosing tanks are installed on the top of the mixing tank 1, each containing a different ratio of chemical solution. A drain pipe is installed at the bottom of the mixing tank 1 below each dosing tank. A metering pump is connected to the drain pipe below each dosing tank. A drain valve is installed at the bottom of the mixing tank 1 for discharging wastewater. The detection component includes a pH sensor 103, an ORP sensor 104, and a conductivity sensor 105 for detecting water quality. 3. The ORP sensor 104 and conductivity sensor 105 can have a built-in battery and wireless data transmission capability. Before use, the metering pump, drain valve, pH sensor 103, ORP sensor 104, and conductivity sensor 105 can be wirelessly connected to an external controller. The pH sensor 103, ORP sensor 104, and conductivity sensor 105 transmit the monitored water quality information to the controller. The controller then controls the metering pumps below each dosing tank to add the appropriate amount of reagent based on the water quality detected by the pH sensor 103, ORP sensor 104, and conductivity sensor 105. It should be noted that the level sensor and temperature sensor that need to be installed inside the mixing tank 1 are existing technologies and will not be described further in this application.

[0024] In this technical solution, a portal frame 21 is fixedly installed on the top of the annular plate 2. A vertical shaft 4 is fixedly connected to one end of the top wall of the portal frame 21. The vertical shaft 4 penetrates the top wall of the mixing tank 1 and the two slide vertically together. Specifically, a sleeve is welded to the top of the mixing tank 1 and fits around the vertical shaft 4. A linear bearing for guiding the vertical shaft 4 is installed inside the sleeve, and a sealing ring is installed inside the sleeve to improve the sealing. When the vertical shaft 4 moves up and down, it can drive the annular plate 2 to move up and down. The detection component is fixedly installed on the inner circumferential wall of the annular plate 2. The annular plate 2 can drive the detection component to move up and down in the water in the mixing tank 1, thereby enabling accurate detection of the water quality.

[0025] The mixing chamber 1 has a base plate 5 fixedly connected to its outer wall. The bottom of the lead screw 6 on the reciprocating screw is rotatably connected to the base plate 5. The outer wall of the lead sleeve 7 on the reciprocating screw has an arm plate 102 fixedly connected at one end to the top of the vertical shaft 4. During the rotation of the lead screw 6, the lead sleeve 7 will reciprocate up and down, thereby driving the vertical shaft 4 to move up and down through the arm plate 102. The external design of the reciprocating screw not only facilitates maintenance but also prevents it from being corroded by water. Therefore, while meeting the requirements of the detection component for accurate water quality detection, it extends the service life of the reciprocating screw. In use, a servo motor 101 is fixedly connected to the bottom of the base plate 5. The output shaft of the servo motor 101 is fixedly connected to the bottom of the lead screw 6, and the servo motor 101 is electrically connected to an external controller.

[0026] Furthermore, an impeller 8 is installed inside the annular plate 2. The impeller 8 is connected to the annular plate 2 via a connecting plate 9. Preferably, there are three impellers 8, which are evenly distributed around the annular plate 2. When the annular plate 2 moves up and down, it drives the impellers 8 to move synchronously. When the impellers 8 move, they interact with the water, causing them to rotate. The water around the impellers 8 rotates, thereby agitating the water and chemicals in the mixing tank 1, ensuring thorough mixing of the chemicals and water. Specifically, one end of the connecting plate 9 is fixedly connected to the top of the annular plate 2, and the other end of the connecting plate 9 is fixedly connected to a positioning sleeve 91. The wheel shaft 81 in the middle of the impeller 8 is fitted inside the positioning sleeve 91, and the two are rotatably connected. During use, a bearing is installed between the positioning sleeve 91 and the wheel shaft 81 to make the rotation of the wheel shaft 81 smoother.

[0027] In this embodiment, a guide shaft 11 is fixedly connected to the middle of the top of the mixing tank 1, and a guide sleeve 211 is fixedly connected to the middle of the top of the gantry frame 21, which is sleeved on the outside of the guide shaft 11. A linear bearing sleeved on the outside of the guide shaft 11 is installed inside the guide sleeve 211. A guide shaft 22 is fixedly connected to the top wall outside the mixing tank 1, and a guide sleeve 2021 sleeved on the guide shaft 212 is fixedly connected to the arm plate 102. A linear bearing sleeved on the outside of the guide shaft 212 is installed inside the guide sleeve 2021. The arrangement of the guide shaft 11 and the guide shaft 212 allows the annular plate 2 to move up and down in the water without jamming.

[0028] In this embodiment, an mounting platform 22 is fixedly connected to the inner peripheral wall of the annular plate 2. Threaded holes are provided on the platform surface of the mounting platform 22. The perforated bases of the pH sensor 103, ORP sensor 104 and conductivity sensor 105 are fixedly mounted on the platform surface of the mounting platform 22 by screws and threaded holes.

[0029] In this embodiment, a manhole 106 located above the detection component is fixedly connected to the top of the mixing chamber 1. The manhole 106 adopts a common flange-type sealing structure. The manhole 106 facilitates the maintenance of the detection component. Since the detection component and the impeller 8 are both installed inside the annular plate 2, the mixing chamber 1 is in a more spacious state, which makes it easier for maintenance personnel to use cleaning tools to clean the inner wall of the mixing chamber 1 through the manhole 106.

[0030] Working principle: When adding chemicals is required, the controller activates the metering pumps at the bottom of each dosing tank and adds a measured amount of chemicals. The chemicals enter the mixing tank 1. After the chemicals are added to the mixing tank 1, they mix with the water. At this time, the control screw 6 rotates, and the sleeve 7 moves up and down under the transmission of the screw 6. Driven by the arm plate 102, the vertical shaft 4 moves up and down. At this time, the annular plate 2 drives the detection component to move up and down. During this process, the blades on the impeller 8 impact the water, and the impeller 8 rotates. When the impeller 8 rotates, it agitates the water around it. At the same time, the up and down movement of the impeller 8 can agitate the water at different heights in the mixing tank 1, so that the chemicals and water are fully mixed.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
