Description

Technical Field

[0001] This application relates to the field of refrigeration equipment, and more particularly to a water chiller unit. Background Technology

[0002] A chiller is a type of refrigeration equipment. In the refrigeration industry, it is divided into air-cooled chillers and water-cooled chillers. Based on the compressor, it is further divided into screw chillers, scroll chillers, etc. Chillers can output refrigerant and are widely used in refrigeration and freezing equipment.

[0003] When existing chiller units are installed, they are connected to the circulating water network. Circulating water enters and exits the chiller unit and undergoes heat exchange, so that the high-temperature circulating water can dissipate heat and cool down in the chiller unit. The chiller unit continuously outputs low-temperature circulating water, enabling equipment such as refrigeration units to work continuously and achieve the purpose of cooling.

[0004] The aforementioned technical solutions have the following drawbacks: during the circulation of water, scale easily forms in the water pipes, causing a decrease in the circulation water flow rate and a lower power output. When scale removal is required, the chiller unit is shut down, making cleaning inconvenient. Utility Model Content

[0005] To facilitate users in cleaning scale without shutting down the system, this application provides a chiller unit.

[0006] The chiller unit provided in this application adopts the following technical solution: A chiller unit includes a unit body and an external pipeline. The unit body is equipped with a water tank. One end of the external pipeline is connected to the water tank, and the other end is equipped with a feeding mechanism. The feeding mechanism includes a feeding pipe and a material box. The feeding pipe is vertically arranged, with its upper end connected to the material box and its lower end connected to the external pipeline. A valve is installed on the feeding pipe, and the opening of the material box is vertically upward.

[0007] By adopting the above technical solution, by setting an external pipe on the unit body and connecting a feeding pipe to the external pipe, the user can pour the scale cleaner into the material box, open the control valve to let the scale cleaner flow into the external pipe and circulate with the circulating water, so that the scale cleaner reacts chemically with the scale in the pipe to achieve the effect of cleaning scale.

[0008] Optionally, a sealing cover is detachably connected to the material box, and the sealing cover is fixed to the material box by bolts.

[0009] By adopting the above technical solution, and by setting a sealing cover on the material box, after the user pours the scale cleaner into the material box, the sealing cover is fixed on the material box, and the valve on the feeding pipe is opened, the circulating water in the water tank can flow into the material box, so that the scale cleaner dissolves and enters the water tank. After the user closes the valve on the feeding pipe, the sealing cover can be opened and the scale cleaner can continue to be added.

[0010] Optionally, the external pipeline is equipped with a detection mechanism, which includes a water outlet pipe. The water outlet pipe is vertically arranged, and its upper end is connected to the external pipeline. A valve is installed on the water outlet pipe.

[0011] By adopting the above technical solution, a detection mechanism is installed on the external pipeline, connecting the outlet pipe to the external pipeline. Users can take a water sample from the water tank by opening the outlet pipe. When the scale cleaner is poured in multiple times, the pH value and other values ​​of the circulating water change, requiring the circulating water to be replaced. Users can take a water sample and test it, thus making it convenient for users to determine whether the circulating water needs to be replaced.

[0012] Optionally, an observation box is connected to the lower end of the water outlet pipe, and the observation box is made of transparent material.

[0013] By adopting the above technical solution, an observation box is installed at the lower end of the water outlet pipe, allowing the circulating water flowing out of the water outlet pipe to enter the observation box. Users can observe the color and impurities contained in the circulating water through the observation box, thus making it convenient for users to check the cleaning quality of the scale cleaner.

[0014] Optionally, a discharge pipe is provided at the bottom of the observation box, and a valve is connected to the discharge pipe.

[0015] By adopting the above technical solution, and by setting a drain pipe at the bottom of the observation box, the user can control the valve on the drain pipe to allow the circulating water in the observation box to flow out, making it convenient for the user to test the water quality of the circulating water.

[0016] Optionally, the water tank is equipped with an exhaust pipe for discharging gas from the water tank.

[0017] By adopting the above technical solution, and by installing an exhaust pipe on the water tank, when the scale cleaner reacts chemically with the scale, it is easy to produce gases such as carbon dioxide. By installing an exhaust pipe on the water tank, the gas in the water tank can be discharged through the exhaust pipe, so that the pressure in the water tank can be kept stable.

[0018] Optionally, the exhaust pipe is vertically arranged, with its lower end connected to the water tank and its upper end positioned above the water tank.

[0019] By adopting the above technical solution and setting the exhaust pipe vertically, when the circulating water is circulating, the gas in the circulating water can accumulate at the top of the exhaust pipe. When the user opens the exhaust pipe and vents the air, the probability of the circulating water flowing out can be reduced.

[0020] Optionally, an overflow valve is provided at the upper end of the exhaust pipe.

[0021] By adopting the above technical solution and installing an overflow valve on the exhaust pipe, when there is a lot of gas in the water tank, the pressure difference between the inside and outside of the exhaust pipe is large. At this time, the overflow valve can automatically operate, so that the gas in the exhaust pipe can be automatically discharged.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By installing a sealing cap on the material tank, after the user pours the scale cleaner into the material tank, by fixing the sealing cap on the material tank and opening the valve on the feeding pipe, the circulating water in the water tank can flow into the material tank, so that the scale cleaner dissolves and enters the water tank. After the user closes the valve on the feeding pipe, the sealing cap can be opened and the scale cleaner can continue to be added. 2. By installing a detection mechanism on the external pipe, the water outlet pipe is connected to the external pipe. Users can take a water sample from the water tank by opening the water outlet pipe. When the scale cleaner is poured in multiple times, the pH value and other values ​​of the circulating water change, and the circulating water needs to be replaced. Users can take a water sample and test it, which makes it convenient for users to determine whether the circulating water needs to be replaced. 3. By installing an exhaust pipe on the water tank, when the scale cleaner reacts chemically with the scale, it easily produces gases such as carbon dioxide. By installing an exhaust pipe on the water tank, the gas inside the water tank can be discharged through the exhaust pipe, thus maintaining a stable pressure inside the water tank.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a chiller unit, referring to... Figure 1 The chiller unit includes a main unit 1 and an external pipe 2. The main unit 1 has multiple water tanks 11 connected to each other. The main unit 1 outputs low-temperature refrigerant to achieve a cooling effect. The external pipe 2 connects to the water tanks 11 and is equipped with a feeding mechanism 21. When the chiller unit has been in use for a long time, scale easily accumulates in the pipes and water tanks 11 of the main unit 1. By adding scale remover into the feeding mechanism 21, the scale remover can enter the main unit 1 and react chemically with the scale, thus cleaning the scale and improving the working efficiency of the main unit 1.

[0028] Reference Figure 1 and Figure 2 The external pipe 2 is horizontally positioned. The feeding mechanism 21 includes a feeding pipe 211 and a feeding box 212. The feeding pipe 211 is vertically positioned, with its lower end connected to the external pipe 2 and its upper end connected to the bottom of the feeding box 212. The opening of the feeding box 212 faces vertically upward. Users pour scale remover into the feeding box 212, allowing the scale remover to enter the water tank 11 through the feeding pipe 211. A valve is installed on the feeding pipe 211 to control the opening and closing of the feeding pipe 211.

[0029] Reference Figure 1 and Figure 2 A sealing cover 213 is detachably connected to the material tank 212. The sealing cover 213 is fixed to the material tank 212 by bolts and is used to seal the opening of the material tank 212. After the user pours the scale cleaner into the material tank 212, the sealing cover 213 is installed on the material tank 212. At this time, the valve is opened so that the water in the water tank 11 can be forced into the feeding pipe 211 and enter the material tank 212, so that the scale cleaner can dissolve in the water and enter the water tank 11. After feeding is completed, the user controls the valve to close. At this time, the user can remove the sealing cover 213 and continue feeding.

[0030] Reference Figure 1An external pipe 2 is equipped with a detection mechanism 22, which includes an outlet pipe 221, an observation box 222, and a discharge pipe 223. The outlet pipe 221 is vertically arranged, with its upper end connected to the external pipe 2 and its lower end connected to the observation box 222. The discharge pipe 223 is vertically connected to the lower side of the observation box 222. Valves are connected to the outlet pipe 221 and the discharge pipe 223 respectively. When the user opens the valve on the outlet pipe 221, the circulating water in the water tank 11 flows into the observation box 222 through the outlet pipe 221. The observation box 222 can be made of transparent material, allowing the user to judge the water quality by observing the color and impurities of the water in the observation box 222, and then pour in different types of scale cleaners through the feeding mechanism 21. When there is circulating water in the observation box 222, the user can open the valve on the discharge pipe 223 to take out a water sample, which facilitates the user to test parameters such as the pH value of the circulating water, and thus helps the user determine whether the circulating water needs to be replaced.

[0031] Reference Figure 1 The water tank 11 is equipped with an exhaust pipe 3, which is vertically installed and connected to the lower end of the water tank 11. The exhaust pipe 3 is used to discharge the gas in the water tank 11. When the scale cleaner reacts chemically with the scale, carbon dioxide and other gases are easily generated in the water tank 11. The exhaust pipe 3 is used to discharge the gas, thereby keeping the pressure in the water tank 11 stable.

[0032] Reference Figure 1 The upper end of the exhaust pipe 3 is positioned higher than that of the water tank 11. When circulating water flows in the water tank 11, gas can accumulate at the upper end of the exhaust pipe 3. An overflow valve 4 is connected to the upper end of the exhaust pipe 3. The overflow valve 4 is used to automatically open and discharge the gas in the exhaust pipe 3. When a large amount of gas is generated in the water tank 11, the pressure inside the water tank 11 is relatively high. At this time, the pressure difference between the inside and outside of the exhaust pipe 3 is large, and the overflow valve 4 can automatically activate and discharge the gas in the exhaust pipe 3.

[0033] The implementation principle of this application embodiment is as follows: by setting an external pipe 2 on the unit body 1, the circulating water in the water tank 11 can be introduced into the material tank 212 and the observation box 222. The user can pour the scale cleaner into the material tank 212, so that the scale cleaner dissolves in the circulating water and enters the water tank 11. There is no need to stop the machine during the process of adding scale cleaner, the probability of circulating water leakage is low, and the user can observe the color and impurities of the circulating water at the observation box 222, so as to conveniently judge the water quality of the circulating water.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
