Description

Technical Field

[0001] The present application relates to the field of temperature control equipment, in particular to a liquid filtering and purifying device used in the field of temperature control equipment, and more particularly to a packing type filtering device. Background Art

[0002] In the field of temperature control equipment, deionized water is often used as a cooling liquid. After a period of use, the anions and cations in the deionized water will increase, resulting in a decrease in the performance of the deionized water. In this case, a deionizer is needed to filter the deionized water after use.

[0003] In the prior art, a plastic filter is usually used and placed in a deionized water cycle. The filter includes a resin tank and a filter tank in sequence according to the water path. The resin tank is used to remove anions and cations in the liquid, and the filter tank is used to filter out resin or impurities in the liquid.

[0004] The filter device in the prior art has a low adaptability to the environment, and generally operates at a temperature between 10 and 60 degrees Celsius. At the same time, the filter element needs to be replaced frequently. The removal process of the resin tank and the filter tank is cumbersome and requires the use of a special removal wrench. Utility Model Content

[0005] In view of this, the present application provides a filler-type filter device for filtering anions and cations in water, and has a high adaptability to the environment and can operate in a larger temperature range. Its specific structure includes: a tank body, which is made of metal, and a accommodating cavity is arranged inside the tank body, and a cylindrical filler is arranged in the accommodating cavity. The top of the tank body is respectively provided with a first opening and a second opening, and a water pipe extends from the first opening toward the bottom of the accommodating cavity, and the water pipe extends to near the bottom of the accommodating cavity, and a first filter screen is arranged at the end of the water pipe; a first joint is arranged at the first opening; a second joint is arranged at the second opening.

[0006] With the above specific structure, the deionized water to be treated enters the water pipe from the first opening, and enters the bottom of the accommodating cavity in the tank body after being filtered by the first filter screen. After filtering by the filler, the anions and cations in the deionized water to be treated are removed. After that, the treated deionized water flows out of the tank body through the second opening. This device plays a role in removing anions and cations in ionized water, and realizes an increase in the resistance value of deionized water. In addition, the metal tank body can adapt to a wider temperature range, which can enhance the environmental adaptability of the filler-type filter device.

[0007] As a possible implementation, the size of the second opening is larger than the diameter of the filler end surface; the size of the second opening is larger than the size of the first opening, and accordingly, the size of the second joint is larger than the size of the first joint.

[0008] With the above possible implementation, the larger second opening facilitates taking out and putting in the filler.

[0009] As a possible implementation, the main body of the first joint is disc-shaped, a connecting pipe extends upward from the upper end of the first joint, a first groove is provided at the lower end of the first joint, a through hole is provided in the first groove, and the through hole is connected to the connecting pipe.

[0010] As a possible implementation, the main body of the second joint is disc-shaped, a connecting pipe extends upward from the center of the second joint, a second groove is provided at the lower end of the second joint, a through hole is provided in the second groove, and the through hole is connected to the connecting pipe.

[0011] As a possible implementation, a limiting platform is sleeved on the bottom end of the connecting pipe.

[0012] With the above possible implementation, the limiting platform is used to limit and fix the filler type filter device in the circulating water circuit.

[0013] As a possible implementation manner, a second filter screen is disposed in the first groove and the second groove.

[0014] By adopting the above possible implementation method, the second filter screen can filter impurities in the deionized water. In addition, the filter screen in the second groove can also filter out fillers in the deionized water to prevent the fillers from entering the water circulation.

[0015] As a possible implementation manner, the first joint is connected to the first opening via a clamp.

[0016] By adopting the above possible implementation method, the clamp connection facilitates the disassembly and installation of the first joint, can achieve a quick connection effect, and is convenient for removing the first joint to maintain and clean the equipment.

[0017] As a possible implementation manner, the second joint is connected to the second opening via a clamp.

[0018] By adopting the above possible implementation method, the clamp connection facilitates the disassembly and installation of the second joint, can achieve a quick connection effect, and is convenient for removing the second joint to maintain and clean the equipment, or replace the packing.

[0019] As a possible implementation, the filler is an anion and cation exchange resin.

[0020] As a possible implementation manner, a tension spring is provided at the lower end of the filler.

[0021] With the above possible implementation, a tension spring is provided at the lower end of the packing, and when the second joint is opened, the tension spring pushes the packing upwards, so as to facilitate the removal of the packing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Below, the specific implementation methods of the present application are described in detail with reference to the accompanying drawings.

[0031] like Figure 1As shown, a packing type filter device for filtering anions and cations used in the prior art is shown. Deionized water in the circulation loop enters the resin tank 1 from the water inlet 3, then enters the filter tank 2 and flows out of the packing type filter device from the water outlet 4. The shell of the packing type filter device is made of plastic and cannot adapt to too high or too low working temperatures. The general working temperature is between 10-60 degrees Celsius. At the same time, the packing type filter device requires frequent replacement of the filter element, and each time the replacement is performed, a specific wrench needs to be used to remove the shell.

[0032] The present application provides a filler type filtering device for filtering anions and cations in water. Figure 2 , 3 As shown, the packing type filter device involved in the embodiment of the present application specifically includes:

[0033] like Figure 2 As shown, a metal tank body 100 is provided with a receiving chamber 110 inside the tank body 100, and a cylindrical filler (not shown) for filtering anions and cations is provided in the receiving chamber 110. A first opening 130 and a second opening 140 are provided at the top of the tank body 100, and a water pipe 120 extends from the first opening 130 toward the bottom of the receiving chamber 110, and the water pipe 120 extends to a position close to the bottom of the receiving chamber 110. A first filter screen 121 is provided at the end of the water pipe 120 for filtering impurities carried from the water circulation in the deionized water.

[0034] like Figure 2 , 3 As shown, the first joint 200 is disposed at the first opening 130 ; the second joint 300 is disposed at the second opening 140 .

[0035] In this embodiment, the material of the tank body 100 is metal, so as to achieve the effect of operating in a wider temperature range: -20 to 150 degrees Celsius. In addition, in other embodiments, other temperature-resistant materials can also be used to make the tank body.

[0036] The size of the second opening 140 is larger than the diameter of the end surface of the filler, so that the filler can be easily taken out from the second opening 140 or put into the accommodating cavity 110 .

[0037] In this embodiment, if Figure 2 , 34, the size of the second opening 140 is larger than the size of the first opening 130, and accordingly, the size of the second connector 300 is larger than the size of the first connector 200. As the water inlet of deionized water, the first opening 130 does not need to be made into a large opening, so that the processing difficulty can be reduced while using a smaller first connector 200, which can reduce the cost. In addition, in other embodiments, the size of the first opening 130 can also be the same as or larger than the size of the second opening 140, which should be selected according to specific usage requirements and scenarios.

[0038] Among them, Figure 5 , 6 As shown, the main body of the first joint 200 is disc-shaped, and a connecting pipe 210 extends upward from the upper end of the first joint 200. A first groove 220 is provided at the lower end of the first joint 200, and a through hole is provided in the first groove 220, and the through hole is connected to the connecting pipe 210. The main body of the second joint 300 is disc-shaped, and a connecting pipe 210 extends upward from the center of the second joint 300. A second groove is provided at the lower end of the second joint 300, and a through hole is provided in the second groove, and the through hole is connected to the connecting pipe 210.

[0039] The first connector 200 is connected to the first opening 130 via a clamp, and the second connector 300 is connected to the second opening 140 via a clamp. The clamp facilitates the assembly and disassembly of the first connector 200 and the second connector 300, and compared with the prior art, it eliminates the trouble of using a specific wrench.

[0040] In this embodiment, a second filter is disposed in the first groove 220 and the second groove to filter the residual filler in the deionized water. In addition, in other embodiments, the second filter may also be disposed at the first opening 130 and the second opening 140 .

[0041] Among them, Figure 3 , 5 As shown, the bottom end of the connecting pipe 210 is sleeved with a limiting platform 211. The limiting platform 211 can be connected to other interfaces in the circulating water circuit, while preventing the connecting pipe 210 from directly contacting the pipeline to cause equipment wear and damage.

[0042] In this embodiment, the filler is an anion and cation exchange resin. In addition, in other embodiments, other materials can be selected as fillers according to actual working conditions or needs.

[0043] A compression spring (not shown) is provided at the lower end of the filler. When the filler is placed in the accommodating chamber 110, the compression spring is compressed by the squeeze of the filler and stores the elastic potential energy. At the same time, the filler is stuck in the accommodating chamber 110 by the second joint 300. When the second joint 300 is opened, the compression spring releases the elastic potential energy into kinetic energy, causing the filler on it to pop up out of the second opening 140, thereby avoiding the operator reaching into the accommodating chamber 110 to grab the filler. Therefore, the design of the compression spring makes it easier to remove the filler and reduces the possibility of contamination in the accommodating chamber 110.

[0044] like Figure 1 , 2 As shown, compared with the packing type filter device in the prior art, the packing type filter device involved in the embodiment provided in the present application has a relatively large tank body 100 and a relatively large containing cavity 110, which can accommodate more deionized water while using larger packing, thereby achieving the effect of improving the filtration efficiency and reducing the number of times the packing is replaced.

[0045] To sum up, compared with the prior art, the packed filter device provided in the present application can be quickly and conveniently disassembled and assembled in the deionized water circulation loop; can adapt to an operating temperature of -20 to 150 degrees Celsius; and has a higher filtering efficiency for deionized water, while the packing needs to be replaced less frequently.

[0046] The term "comprising" used throughout the present application should not be interpreted as being limited to what is listed thereafter; it does not exclude other structural elements or steps.

[0047] It can be understood that those skilled in the art can combine the features mentioned in one or more embodiments mentioned in the entire application with the features in other embodiments in any appropriate manner to implement the application.

[0048] Note that the above are only preferred embodiments of the present application and the technical principles used. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present application. Therefore, although the present application is described in more detail through the above embodiments, the present application is not limited to the above embodiments, and may also include more other equivalent embodiments without departing from the technical concept of the present application, all of which belong to the protection scope of the present application.
