Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to a water-cooled water chiller. Background Art

[0002] A water chiller is a water cooling device that can provide constant temperature, constant flow and constant pressure. The principle of a water chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then inject the low-temperature frozen water into the equipment that needs to be cooled by the water pump inside the machine. The frozen water takes away the heat inside the machine and returns the high-temperature hot water to the water tank for cooling. This cycle of exchange cooling achieves the effect of cooling the equipment.

[0003] A water-cooled chiller with a filtering function is disclosed in a Chinese utility model patent with publication number CN220567614U, comprising a workbench, a hollow tank is fixedly connected to the middle end of the top of the workbench, a long tube is connected to the middle end of the bottom of the hollow tank, a leg is fixedly connected to the bottom of the workbench, the bottom of the long tube passes through the workbench and the leg in sequence, and a support column is fixedly connected to the middle right portion of the inner side of the leg.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned technical means can only filter impurities in the water source, but are not convenient for adjusting the calcium and magnesium ion content in hard water, and it is difficult to convert hard water into soft water. After long-term use, water with excessively high hardness is prone to scale inside the water channel, blocking the water flow, reducing cooling efficiency, and even damaging the cooler. Therefore, improvements are needed. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a water-cooled chiller.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a water-cooled chiller, comprising a chiller body, a water tank is arranged above the chiller body, a water inlet pipe is fixed on one side of the water tank and connected to the water tank, the end of the water inlet pipe away from the water tank is connected to an external water source, a calcium-magnesium hardness detector for detecting the water quality in the water tank is fixed on the side wall of the water tank, a soft water pipe for connecting the water tank and the chiller body is fixed at the bottom of the water tank, a first solenoid valve is arranged at a position of the soft water pipe near the bottom of the water tank, a hard water pipe is fixed at the bottom of the water tank and connected to the water tank, a second solenoid valve is arranged at a position of the hard water pipe near the bottom of the water tank, a hard water softening treatment tank is fixed at the lower end of the hard water pipe and connected to the water softening treatment tank, the liquid outlet of the hard water softening treatment tank is connected to the chiller body through a connecting pipe, a third solenoid valve is arranged on the connecting pipe, and a first controller electrically connected to the calcium-magnesium hardness detector, the first solenoid valve, the second solenoid valve and the third solenoid valve is fixed on the side wall of the water tank.

[0007] By adopting the above technical scheme, in order to reduce the probability of scaling inside the water channel and reducing water flow due to water with too high hardness, the staff first opens the valve of the water inlet pipe connected to the external water source, and the water will flow into the water tank along the water inlet pipe. When the water tank is full of water, the staff closes the valve and then opens the calcium-magnesium hardness detector through the first controller. The detection end of the calcium-magnesium hardness detector extends into the water tank. The calcium-magnesium hardness detector detects the calcium and magnesium content in the water source in the water tank to determine whether the water quality is soft water or hard water. When the calcium and magnesium content in every 1000ppm of water reaches 0-60ppm, it is soft water, and when the calcium and magnesium content in every 1000ppm of water exceeds 60-120ppm, it is hard water. The calcium-magnesium hardness detector transmits the results of water hardness and softness detection to the first controller in real time. When the water quality is detected to be soft water, the first controller controls the first solenoid valve to start, so that the water flows directly into the pipe inside the chiller through the soft water pipe for refrigeration, so as to cool the product. When the water quality is detected to be hard water, the first controller controls the second solenoid valve to start, so that the water flows through the hard water pipe to the hard water softening treatment box for treatment. The treated water then flows into the pipes inside the chiller for refrigeration, which helps to reduce the probability of hard water directly flowing into the pipes and scaling inside the pipes, and extend the service life of the chiller.

[0008] Furthermore, a box cover is hinged on the top of the hard water softening treatment box, and a feeding pipe connected to the inside of the hard water softening treatment box is fixed on the top of the box cover.

[0009] By adopting the above technical solution, the staff transports the softening salt to the hard water softening treatment box through the feeding pipe. The softening salt (also known as ion exchange resin regeneration agent) has sodium chloride as its main chemical component. It exchanges with the calcium and magnesium ions in the water through the principle of ion exchange, thereby absorbing the excess calcium and magnesium ions in the water, achieving the purpose of removing scale (calcium carbonate or magnesium carbonate).

[0010] Furthermore, a filter screen is provided in the hard water softening treatment box, and the filter screen is located below the lower end of the hard water pipe. L-shaped connecting rods are symmetrically fixed on both sides of the filter screen. The inner wall of the hard water softening treatment box is symmetrically provided with sliding grooves for the L-shaped connecting rods to slide with, and the horizontal section of the L-shaped connecting rod is located above the filter screen.

[0011] By adopting the above technical solution, the filter net intercepts impurities in the water, removes suspended matter, particulate matter and other impurities in the water body, and the sliding cooperation between the slide groove and the L-shaped connecting rod facilitates the installation and disassembly of the filter net by the staff.

[0012] Furthermore, a stirring assembly is provided on the hard water softening treatment box, and the stirring assembly includes a motor fixed on the box cover, the output shaft of the motor passes through the box cover and is rotatably connected to the box cover, the stirring assembly also includes a central shaft connected to the lower end of the output shaft of the motor through a coupling, and a stirring rod fixed on the side wall of the central shaft, the central shaft passes through the filter screen and cooperates with the filter screen, and the stirring rod is located below the filter screen.

[0013] By adopting the above technical solution, the staff starts the motor, and after the motor starts working, it drives the coupling, the central shaft and the stirring rod to rotate around the axis of the central shaft, which is conducive to the full integration of the soft water salt and the water source, and improves the efficiency of hard water softening.

[0014] Furthermore, the hard water softening treatment box is funnel-shaped, and a filter is provided in the hard water softening treatment box near the water outlet.

[0015] By adopting the above technical solution, the hard water softening treatment box is funnel-shaped, which can guide the softened water source to the liquid outlet more quickly. The filter element can further filter impurities in the softened water source, which is beneficial to reduce the probability of impurities entering the chiller pipeline.

[0016] Furthermore, the filter element is a hemispherical filter mesh body, and the hemispherical filter mesh body is integrally formed with an annular plate body near its edge, and the bottom of the annular plate body is in contact with the inner wall of the hard water softening treatment box near the connecting pipe.

[0017] By adopting the above technical solution, due to gravity and the direction of water flow, impurities can be concentrated at the center of the hemispherical filter body, and the annular plate body is convenient for workers to install or disassemble the hemispherical filter body.

[0018] Furthermore, a second controller electrically connected to the motor is provided on a side wall of one side of the chiller body.

[0019] By adopting the above technical solution, the staff can control the operation of the motor through the second controller.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, in order to reduce the probability of scaling inside the water channel and reducing the water flow caused by water with too high hardness, the staff first opens the valve of the water inlet pipe connected to the external water source, and the water will flow into the water tank along the water inlet pipe. When the water tank is full of water, the staff closes the valve and then turns on the calcium-magnesium hardness detector through the first controller. The detection end of the calcium-magnesium hardness detector extends into the water tank. The calcium-magnesium hardness detector detects the calcium and magnesium content in the water source in the water tank to determine whether the water quality is soft water or hard water. When the calcium and magnesium content in every 1000ppm of water reaches 0-60ppm, it is soft water, and when the calcium and magnesium content in every 1000ppm of water exceeds 60-120ppm, it is hard water. The calcium-magnesium hardness detector transmits the results of the water hardness and softness detection to the first controller in real time. When the water quality is detected to be soft water, the first controller controls the first solenoid valve to start, so that the water flows directly into the pipe inside the chiller through the soft water pipe for refrigeration, so as to cool the product. When the water quality is detected to be hard water, the first controller controls the second solenoid valve to start, so that the water flows through the hard water pipe to the hard water softening treatment box for treatment, and the treated water source then flows into the pipe inside the chiller for refrigeration, which is beneficial to reduce the probability of hard water directly flowing into the pipe and scaling inside the pipe, and prolong the service life of the chiller;

[0022] 2. In this application, the staff transported the softening salt to the inside of the hard water softening treatment box through the feeding pipe. The main chemical component of the softening salt (also known as the ion exchange resin regeneration agent) is sodium chloride, which exchanges with the calcium and magnesium ions in the water through the principle of ion exchange, thereby absorbing the excess calcium and magnesium ions in the water to achieve the purpose of removing scale (calcium carbonate or magnesium carbonate);

[0023] 3. In this application, the staff starts the motor, and after the motor starts working, it drives the coupling, the central shaft and the stirring rod to rotate around the axis of the central shaft, which is conducive to the full integration of the soft water salt and the water source, and improves the efficiency of hard water softening.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-5 As shown, an embodiment of the present application discloses a water-cooled chiller, including a chiller body 1, a water tank 2, a calcium and magnesium hardness detector 3, a hard water softening treatment tank 4, a stirring assembly 6 and a filter 5.

[0032] The chiller body 1 is arranged horizontally, the water tank 2 is arranged above the chiller body 1, a water inlet pipe 21 is fixed and connected to one side of the water tank 2, and the end of the water inlet pipe 21 away from the water tank 2 is connected to an external water source. A soft water pipe 22 for connecting the water tank 2 and the chiller body 1 is fixed at the bottom of the water tank 2, a first solenoid valve 23 is arranged at the position of the soft water pipe 22 near the bottom of the water tank 2, a hard water pipe 23 is fixed and connected to the bottom of the water tank 2, and a second solenoid valve 25 is arranged at the position of the hard water pipe 23 near the bottom of the water tank 2.

[0033] The calcium and magnesium hardness detector 3 is fixed on the side wall of the water tank 2, and the detection end of the calcium and magnesium hardness detector 3 extends into the water tank 2 to detect the water quality in the water tank 2. When the calcium and magnesium content in every 1000ppm of water reaches 0-60ppm, it is soft water; when the calcium and magnesium content in every 1000ppm exceeds 60-120ppm, it is hard water.

[0034] The hard water softening treatment box 4 is fixed to the lower end of the hard water pipe 23 and communicated with the hard water pipe 23. The liquid outlet of the hard water softening treatment box 4 is communicated with the chiller body 1 through a connecting pipe 26, and a third solenoid valve 27 is provided on the connecting pipe 26. A first controller 28 electrically connected to the calcium-magnesium hardness detector 3, the first solenoid valve 23, the second solenoid valve 25 and the third solenoid valve 27 is fixed on the side wall of the water tank 2. In this embodiment, when the calcium-magnesium content in every 1000ppm of water reaches 0-60ppm, it is soft water, and when the calcium-magnesium content in every 1000ppm of water exceeds 60-120ppm, it is hard water. The results of the water hardness detection by the calcium-magnesium hardness detector 3 are transmitted to the first controller 28 in real time. When the water quality is detected to be soft water, the first controller 28 controls the first solenoid valve 23 to start, so that the water flows directly into the pipe inside the chiller through the soft water pipe 22 for refrigeration, so as to cool the product. When the water quality is detected to be hard water, the first controller 28 controls the second solenoid valve 25 to start, so that the water flows through the hard water pipe 23 to the hard water softening treatment box 4 for treatment. The treated water source then flows into the pipe inside the chiller for refrigeration, which is beneficial to reduce the probability of hard water directly flowing into the pipe and scaling inside the pipe, and prolong the service life of the chiller.

[0035] The stirring assembly 6 is arranged on the hard water softening treatment box 4, and the stirring assembly 6 includes a motor 61, a coupling 62, a central shaft 63 and a stirring rod 64. The motor 61 is fixed on the box cover 41, and the output shaft of the motor 61 passes through the box cover 41 and is rotatably connected with the box cover 41. The coupling 62 is connected to the lower end of the output shaft of the motor 61 by bolts, and the central rod is connected to the lower end of the coupling 62 by bolts. The stirring rod 64 is fixed on the side wall of the central shaft 63, and the stirring rod 64 is provided with a plurality of stirring rods and is evenly distributed about the axis of the central shaft 63. In this embodiment, the staff starts the motor 61, and after the motor 61 works, it drives the coupling 62, the central shaft 63 and the stirring rod 64 to rotate around the axis of the central shaft 63, which is conducive to the full fusion of the soft water salt and the water source, and improves the efficiency of hard water softening.

[0036] In this embodiment, the filter element 5 is a hemispherical filter screen 44, and a ring-shaped plate body 52 is integrally formed near the edge of the hemispherical filter screen 44. The bottom of the ring-shaped plate body 52 is in contact with the inner wall of the hard water softening treatment box 4 near the connecting pipe 26. Due to gravity and the direction of water flow, impurities can be concentrated at the center of the hemispherical filter screen 44. The ring-shaped plate body 52 is convenient for workers to install or remove the hemispherical filter screen 44.

[0037] In order to facilitate the staff to transport the soft water salt to the hard water softening treatment box 4, a box cover 41 is hinged on the top of the hard water softening treatment box 4, and a feeding pipe 42 connected to the hard water softening treatment box 4 is fixed on the top of the box cover 41. The main chemical component of the soft water salt (also known as the ion exchange resin regeneration agent) is sodium chloride, which exchanges with calcium and magnesium ions in water through the principle of ion exchange, thereby absorbing excess calcium and magnesium ions in the water to achieve the purpose of removing scale (calcium carbonate or magnesium carbonate).

[0038] In order to facilitate the interception of impurities in the water and the removal of suspended matter, particulate matter and other impurities in the water, a filter screen 44 is arranged in the hard water softening treatment box 4. The filter screen 44 is located below the lower end of the hard water pipe 23. In order to facilitate the installation and removal of the filter screen 44 by the staff, symmetrically arranged L-shaped connecting rods 441 are fixed on both sides of the filter screen 44. The inner wall of the hard water softening treatment box 4 is symmetrically provided with slide grooves 43 for the L-shaped connecting rod 441 to slide with. The horizontal section of the L-shaped connecting rod 441 is located above the filter screen 44.

[0039] In order to facilitate the staff to control the operation of the motor 61 , a second controller 11 electrically connected to the motor 61 is provided on the side wall of one side of the chiller body 1 .

[0040] The operating principle of a water-cooled chiller in this embodiment is as follows: in order to reduce the probability of scaling inside the water channel and reducing the water flow caused by water with too high hardness, the staff first opens the valve of the water inlet pipe 21 connected to the external water source, and the water flows into the water tank 2 along the water inlet pipe 21. When the water tank 2 is full of water, the staff closes the valve and then opens the calcium-magnesium hardness detector 3 through the first controller 28. The detection end of the calcium-magnesium hardness detector 3 extends into the water tank 2, and the calcium-magnesium content in the water source in the water tank 2 is detected by the calcium-magnesium hardness detector 3. To determine whether the water quality is soft water or hard water, when the calcium and magnesium content in every 1000ppm of water reaches 0-60ppm, it is soft water, and when the calcium and magnesium content in every 1000ppm of water exceeds 60-120ppm, it is hard water. The calcium and magnesium hardness detector 3 transmits the results of water softness and hardness detection to the first controller 28 in real time. When the water quality is detected to be soft water, the first controller 28 controls the first solenoid valve 23 to start, so that the water flows directly into the pipe inside the chiller through the soft water pipe 22 for refrigeration, so as to cool the product. When the water quality is detected to be hard water, the first controller 28 controls the second solenoid valve 25 to start, so that the water flows through the hard water pipe 23 to the hard water softening treatment box 4 for treatment. The staff transports the soft water salt to the hard water softening treatment box 4 through the feeding pipe 42. The soft water salt (also known as the ion exchange resin regeneration agent) has sodium chloride as its main chemical component. It exchanges with the calcium and magnesium ions in the water through the principle of ion exchange, thereby absorbing the excess calcium and magnesium ions in the water to achieve the purpose of removing scale (calcium carbonate or magnesium carbonate). The treated water source then flows into the pipe inside the chiller for refrigeration, which is beneficial to reduce the probability of hard water directly flowing into the pipe and scaling inside the pipe, and prolong the service life of the chiller.
