Description

Technical Field

[0001] The utility model mainly relates to the technical field of purified water, and particularly relates to a temperature-adjustable constant-temperature purified water device. Background Technique

[0002] Purified water equipment is used to produce a kind of water with extremely high purity. It can almost completely remove the conductive medium in the water, and at the same time remove the gases, colloids and organic substances that are not easily dissociated to a very low level. Purified water equipment is used to meet the needs of various industries to produce purified water, and is mostly used in industries such as medicine, biochemistry and chemical engineering, and hospitals. The whole system is composed of all stainless steel materials, and ultraviolet and ozone sterilization devices must be installed before the water use point. In some countries, the use of ozone is not allowed, so the system adopts pasteurization. The core technology of purified water equipment adopts the latest processes such as reverse osmosis, and a complete set of high-purity water treatment processes are designed more specifically to meet the water use requirements for the production of purified water and large infusion in pharmaceutical factories and hospitals.

[0003] For example, Chinese Patent Publication No. CN209412004U discloses a purified water constant-temperature water production device that can be purified at multiple levels, including a water production tank. A reverse osmosis tank is fixedly connected to the top of the inner cavity of the water production tank. A reverse osmosis membrane is fixedly connected to the inner cavity of the reverse osmosis tank, and the reverse osmosis membrane divides the reverse osmosis tank into a stirring tank and a filtering tank. A rotating rod is arranged in the inner cavity of the stirring tank. A swinging leaf is fixedly connected to the outer surface of the rotating rod. One end of the rotating rod is in transmission connection with the output shaft of the driving motor.

[0004] In the above application, a rotating rod is arranged in the inner cavity of the stirring tank. A swinging leaf is fixedly connected to the outer surface of the rotating rod. One end of the rotating rod is in transmission connection with the output shaft of the driving motor. There are two swinging leaves in total, and the two swinging leaves are symmetrically distributed with respect to the horizontal center line of the rotating rod. A plurality of round holes are opened on the outer surface of the rotating rod. During use, the swinging leaves in the stirring tank rotate continuously, and the water in the stirring tank flows through the reverse osmosis membrane into the filtering tank, realizing sufficient stirring and improving the water production efficiency. However, in the prior art, in some environments, low-temperature purified water is required. For example, in some experiments, strict temperature requirements are imposed. Using low-temperature purified water can avoid the influence of temperature fluctuations on the experimental results and improve the accuracy of the experiment. However, in the above application, it is not convenient to adjust the temperature of the purified water, especially to lower the temperature of the purified water. Content of the Utility Model

Embodiment

[0029] Referring to the attached Figures 1 to 5 , a temperature-adjustable constant-temperature purified water device, comprising a frame 1, a water storage tank 2 is arranged on the frame 1, an air-cooling mechanism 3 is arranged above the water storage tank 2, an adjusting mechanism 8 is arranged between the water storage tank 2 and the air-cooling mechanism 3, the adjusting mechanism 8 is used to adjust the air outlet position of the air-cooling mechanism 3, a refrigerant storage tank 4 is further arranged on one side of the frame 1, the refrigerant storage tank 4 is connected to a heat exchanger 5 through a refrigeration water pump 6, and the water storage tank 2 is connected to the heat exchanger 5 through a delivery pump 7.

[0030] The air-cooling mechanism 3 includes a mounting bracket 31 fixed to the frame 1. A number of fans 34 are arranged on the mounting bracket 31. A connecting hose 32 is provided at the lower end of the mounting bracket 31. A air guide opening 33 is provided at the lower end of the connecting hose 32. The air guide opening 33 is connected to the adjustment mechanism 8. An installation groove 36 is provided on the mounting bracket 31. The fan 34 is fixed in the installation groove 36. The refrigeration water pump 6 and the refrigerant storage tank 4 are connected by a refrigerant delivery pipe 35. The refrigerant delivery pipe 35 is arranged inside the mounting bracket 31.

[0031] The adjustment mechanism 8 includes two symmetrically arranged bearing seats 82. A screw rod 84 is rotatably installed in the bearing seat 82 through a bearing 83. A threaded sleeve 86 is installed on the screw rod 84 through a thread. A moving plate 87 is arranged on the threaded sleeve 86. The bearing seat 82 is fixedly installed on a support plate 81. The support plate 81 is fixed to the upper end of the water storage tank 2. A motor 85 is fixedly installed on one of the bearing seats 82. The output end of the motor 85 is connected to the screw rod 84.

[0032] Working principle: Set to 5 degrees Celsius in summer. During operation, the purified water enters the heat exchanger 5 through the pipeline and exchanges heat with the refrigerant. After the water is cooled, it is sent out. The refrigeration compressor compresses the refrigerant, dissipates heat in the condenser, and then enters the heat exchanger 5 through the expansion valve to complete the cycle. In other embodiments: A heating device is also provided in the water storage tank 2. Set to 30 degrees Celsius according to requirements in winter. The system electrically heats the water tank, and at the same time uses the heat exchanger 5 to circulate and heat the purified water.

[0033] A three-way regulating valve is provided at the outlet of the heat exchanger 5. One outlet of the three-way regulating valve is connected to the water storage tank 2, and the other outlet is connected to a water receiving container. A temperature sensor is arranged on the pipeline between the water receiving container and the three-way regulating valve. A weighing module is arranged at the lower end of the water receiving container. When the temperature sensor detects the set temperature, the three-way regulating valve starts to work. The accuracy of the three-way regulating valve is one-thousandth, and it can accurately control the temperature of the purified water within plus or minus 0.5 degrees of the set temperature.

[0034] The weighing module is used to measure and weigh the water volume added to the water receiving container. When the added water volume reaches the set value of 55 kilograms, the water addition control valve is closed. Using the precise weighing module and the fast response control valve, the quantitative water addition weight error can be controlled within one-thousandth.

[0035] The air-cooling mechanism 3 is located above the water storage tank 2, and its air outlet position can be adjusted by the adjustment mechanism 8. The cold air generated by the air-cooling mechanism 3 directly blows towards the water storage tank 2 and exchanges heat with the purified water in the water storage tank 2, thereby reducing the temperature of the purified water. The fan 34 is fixed in the installation groove 36 of the mounting bracket 31 and generates wind by rotation. The refrigerant delivery pipe 35 is arranged in the mounting bracket 31 and delivers the refrigerant from the refrigerant storage tank 4 to the refrigeration water pump 6. When the wind passes through the refrigerant delivery pipe 35, it becomes cold air. The cold air is delivered to the air guide port 33 through the connecting hose 32. The air guide port 33 is connected to the adjustment mechanism 8, and the adjustment mechanism 8 can control the position and direction of the air guide port 33, so that the cold air can evenly blow towards the water storage tank 2.

[0036] The air-cooling mechanism 3 uses the fan 34 to generate cold air. Compared with other cooling methods, it has the advantages of simple structure, low cost, and convenient maintenance. The setting of the connecting hose 32 enables the position and direction of the air guide port 33 to be adjusted more flexibly, so that the cold air can blow towards the water storage tank 2 more evenly, improving the cooling effect.

[0037] The motor 85 starts and drives the screw 84 to rotate. Since the screw 84 is threadedly connected to the threaded sleeve 86, the rotation of the screw 84 will cause the threaded sleeve 86 to move along the screw 84. The threaded sleeve 86 is connected to the moving plate 87, and the movement of the threaded sleeve 86 will drive the moving plate 87 to move. The moving plate 87 is connected to the air guide port 33 of the air-cooling mechanism 3, and the movement of the moving plate 87 will change the position of the air guide port 33. By the forward and reverse rotation of the motor 85, the left and right movement of the air guide port 33 can be realized, thereby adjusting the air outlet position of the air-cooling mechanism 3.

[0038] The refrigerant in the refrigerant storage tank 4 is delivered to the shell side of the heat exchanger 5 by the refrigeration water pump 6. The purified water in the water storage tank 2 is also delivered to the tube side of the heat exchanger 5 by the delivery pump 7. In the heat exchanger 5, the refrigerant exchanges heat with the purified water, and the refrigerant absorbs the heat in the purified water, further reducing the temperature of the purified water. Through the synergistic effect of the air-cooling mechanism 3 and the heat exchanger, the device can effectively cool the purified water to the required temperature.

[0039] The above-described embodiments only express certain implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
