Description

Technical Field

[0001] This utility model relates to the field of ultrapure water processing technology, and in particular to a filtration device for ultrapure water filtration. Background Technology

[0002] Ultrapure water filtration equipment is a device used to treat water to an extremely high level of purity. Ultrapure water has very high purity requirements and usually contains very few ions, particles, microorganisms, and organic matter. Ultrapure water filtration equipment removes impurities from the water step by step through a variety of physical and chemical processes to achieve the required pure water standards.

[0003] In the production and processing of ultrapure water, the ultrapure water filtration equipment serves as the core preparation device. Through multi-stage filtration technologies such as reverse osmosis, ion exchange, and ultrafiltration, it removes almost all impurities, microorganisms, and organic matter from the water. The control box installed on the equipment is responsible for real-time monitoring of water quality parameters, adjusting the filtration process, and controlling the operation of water pumps and valves. It is the "nerve center" that ensures the stable and efficient operation of the ultrapure water filtration process. When the control box is in use, the internal electrical equipment generates heat, which accumulates inside the control box. Traditional heat dissipation methods usually involve opening several ventilation holes on both sides of the control box to connect with the outside air for heat dissipation. However, this method cannot automatically expel the hot air inside the control box, resulting in limited heat dissipation and easily causing the internal temperature of the control box to become too high. This can affect the normal operation of the electrical equipment, reduce the equipment's lifespan, and affect the processing of ultrapure water. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for ultrapure water filtration, aiming to solve the problems in the prior art.

[0005] This invention is implemented as follows: a filtration device for ultrapure water filtration includes a support frame on which several coarse filters, reverse osmosis components, ion exchange components, and ultrafiltration components are mounted. Water is initially filtered through the coarse filters and then enters the reverse osmosis component through a pipe. The water treated by the reverse osmosis component enters the ion exchange component through a pipe, and the water treated by the ion exchange component enters the ultrafiltration component through a pipe. The ultrafiltration component discharges ultrapure water. A control box is located on one side of the support frame, and a cooling and heat dissipation device is located on one side of the control box. The cooling and heat dissipation device can reduce the temperature of the air inside the airbox through a semiconductor cooling chip, and then spray it into the interior of the control box through a guide pipe and a nozzle frame to further cool the hot air inside. The hot air inside the control box is then discharged autonomously from the heat dissipation holes, achieving a rapid heat dissipation effect.

[0006] Preferably, the cooling and heat dissipation device includes a wind box, wherein one side of the wind box is fixedly installed on one side of the control box; an air pump, wherein the air pump is fixedly installed on one side of the inlet of the wind box; a thermoelectric cooler, wherein one side of the thermoelectric cooler is fixedly installed on one side of the wind box; two guide pipes, wherein both ends of the two guide pipes are symmetrically installed through one side of the wind box and the control box respectively; and a nozzle frame, wherein the outer surface of the nozzle frame is connected through one end of the two guide pipes.

[0007] Preferably, the cooling and heat dissipation device further includes a plurality of filter screens, wherein the outer surface of the filter screens is fixedly installed in the inner wall of the nozzle frame outlet.

[0008] Preferably, both ends of the nozzle frame are fixedly mounted with round hole frames, and one side of the round hole frame is fixedly mounted on one side of the inner wall of the control box.

[0009] Preferably, reinforcing rods are fixedly installed on both sides of several ends of the bellows, and one side of the reinforcing rod is fixedly installed on one side of the control box.

[0010] Preferably, a plurality of guide plates are fixedly installed on the inner wall of the wind box, wherein the plurality of guide plates are symmetrically and alternately distributed in the inner wall of the wind box.

[0011] Preferably, the cooling and heat dissipation device further includes an auxiliary mechanism, which includes a cooling guide frame, one side of which is fixedly installed on one side of the control box; and two cooling guide plates, one end of which is symmetrically inserted through one side of the control box and fixedly connected to one side of the cooling guide frame, while the other ends are fixedly installed on one side of the air box and one side of the semiconductor cooling plate, respectively.

[0012] Preferably, a plurality of connecting plates are fixedly installed on both sides of one end of the cooling plate, wherein the two sides of the connecting plates are respectively fixedly installed on one side of the air box and one side of the semiconductor cooling plate, and the connecting plates, cooling plates and cooling brackets are all made of copper.

[0013] The beneficial effects of the filtration device for ultrapure water filtration disclosed in this utility model are:

[0014] 1. In the production and processing of ultrapure water, water is first introduced from the input end of the coarse filter. The coarse filter initially filters out large particles of impurities. The water passing through the coarse filter is transported along the pipeline to the reverse osmosis unit. Inside the reverse osmosis unit, the reverse osmosis membrane intercepts larger organic particles, bacteria, and viruses in the water. The water treated by the reverse osmosis unit enters the ion exchange unit. In the ion exchange unit, ions in the water undergo an exchange reaction to remove dissolved salts. The water treated by the ion exchange unit enters the ultrafiltration unit. The ultrafiltration unit uses a membrane to screen out colloids, suspended solids, bacteria, viruses, and large molecular organic matter in the water. The water treated by the ultrafiltration unit meets the ultrapure water standard and is discharged.

[0015] 2. By installing a cooling and heat dissipation device, when the control box is in use, the semiconductor cooling chip can be connected to the power supply, and then the air pump can be started to draw air into the air box, allowing it to come into contact with the air box interior to exchange heat and lower the temperature. Then, the air flows into the guide pipe and is sprayed into the control box interior through the nozzle frame, where it exchanges heat with the hot air inside the control box. The hot air is then actively discharged from the heat dissipation holes, achieving a rapid cooling effect. This prevents the internal temperature of the control box from becoming too high, which could affect the normal operation of electrical equipment, extend the service life of the equipment inside the control box, and avoid affecting the processing of ultrapure water.

[0023] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] In this embodiment:

[0025] Reference Figure 1 The diagram shows a preferred embodiment of the present invention.

[0026] This embodiment of a filtration device for ultrapure water filtration includes a support 1. The support 1 is equipped with several coarse filters 4, a reverse osmosis component 6, an ion exchange component 7, and an ultrafiltration component 5. Water is initially filtered through the coarse filters 4 and then enters the reverse osmosis component 6 via a pipe. The water treated by the reverse osmosis component 6 enters the ion exchange component 7 via a pipe, and the water treated by the ion exchange component 7 enters the ultrafiltration component 5 via a pipe. The ultrafiltration component 5 discharges the ultrapure water. A control box 3 is located on one side of the support 1, and a cooling and heat dissipation device 2 is located on one side of the control box 3. The cooling and heat dissipation device 2 uses a semiconductor cooling chip 23 to exchange heat with the air inside the airbox 21 to lower its temperature. The air is then sprayed into the control box 3 through a guide pipe 24 and a nozzle frame 25 to exchange heat with and cool the hot air inside, allowing the hot air to be discharged autonomously from the heat dissipation holes, achieving a rapid heat dissipation effect.

[0027] Figure 1-4The cooling and heat dissipation device 2 shown includes a blower box 21, one side of which is fixedly mounted on one side of the control box 3; an air pump 22, which is fixedly mounted on one side of the inlet of the blower box 21; a thermoelectric cooler 23, one side of which is fixedly mounted on one side of the blower box 21; two guide pipes 24, both ends of which are symmetrically installed through one side of the blower box 21 and the control box 3 respectively; and a nozzle frame 25, the outer surface of which is connected through one end of the two guide pipes 24. By installing a cooling and heat dissipation device 2, during the production and processing of ultrapure water, water is first introduced from the input end of the coarse filter 4. The coarse filter 4 initially filters out large particles of impurities. The water passing through the coarse filter 4 is then transported along the pipeline to the reverse osmosis unit 6. Inside the reverse osmosis unit 6, the reverse osmosis membrane removes larger organic particles, bacteria, and viruses from the water. The water treated by the reverse osmosis unit 6 then enters the ion exchange unit 7. In the ion exchange unit 7, ions exchange with the water to remove dissolved salts. The water treated by the ion exchange unit 7 then enters the ultrafiltration unit 5. The ultrafiltration unit 5 uses a membrane to screen out colloids, suspended solids, bacteria, viruses, and large molecular organic matter from the water. The water treated by the ultrafiltration unit 5 reaches ultrapure water quality. The standard discharge of pure water is handled by the control box 3 installed on the equipment, which is responsible for real-time monitoring of water quality parameters, adjustment of the filtration process, and control of the operation of water pumps and valves. When the control box 3 is in use, the semiconductor cooling chip 23 can be connected to the power supply, and then the air pump 22 can be started to draw air into the air box 21, so that it comes into contact with the inside of the air box 21 to exchange heat and reduce the temperature. Then it flows into the guide pipe 24 and is sprayed into the inside of the control box 3 through the nozzle frame 25, so that it exchanges heat with the hot air inside the control box 3. The hot air is actively discharged from the heat dissipation hole to achieve a rapid cooling effect, so as to avoid the internal temperature of the control box 3 being too high and affecting the normal operation of electrical equipment, improve the service life of the internal equipment of the control box 3, and avoid affecting the processing of ultrapure water.

[0028] Figure 1-4 The cooling and heat dissipation device 2 shown also includes several filters 27, the outer surfaces of which are fixedly installed in the inner wall of the nozzle frame 25 at the outlet. By installing the filters 27, the inner wall of the nozzle frame 25 at the outlet can be protected, preventing external dust and impurities from entering the nozzle frame 25 during use and avoiding blockage. Circular hole brackets 28 are fixedly installed on the outer surfaces of both ends of the nozzle frame 25, with one side of the circular hole bracket 28 fixedly installed on one side of the inner wall of the control box 3. By installing the circular hole brackets 28, the two sides of the nozzle frame 25 can be supported and reinforced, preventing it from shaking during use.

[0029] Figure 1-4The bellows 21 shown has reinforcing rods 29 fixedly installed on both sides of several ends, with one side of each reinforcing rod 29 fixedly installed on one side of the control box 3. By installing the reinforcing rods 29, the connection area between one side of the bellows 21 and the control box 3 can be increased, making the connection more secure and stable, and less prone to damage. Several guide vanes 210 are fixedly installed on the inner wall of the bellows 21, and these guide vanes 210 are symmetrically and alternately distributed within the inner wall of the bellows 21. By installing the guide vanes 210, the airflow path inside the bellows 21 can be extended, allowing it to fully contact the inner wall of the bellows 21 and accelerating the cooling rate.

[0030] Figure 1-4 As shown, the cooling and heat dissipation device 2 also includes an auxiliary mechanism 26. The auxiliary mechanism 26 includes a cooling guide frame 261, one side of which is fixedly installed on one side of the control box 3; and two cooling plates 262, one end of which symmetrically penetrates one side of the control box 3 and is fixedly connected to one side of the cooling guide frame 261, while the other ends are fixedly installed on one side of the air box 21 and one side of the thermoelectric cooler 23, respectively. By setting up the auxiliary mechanism 26, when the thermoelectric cooler 23 cools the surface of the air box 21, it also cools the temperature of the cooling plates 262, which is then conducted to the cooling guide frame 261. The cooling guide frame 261 contacts the inner wall of the control box 3 to exchange heat and reduce the temperature, thus enhancing the cooling effect and preventing the inside of the control box 3 from overheating and being damaged. Several connecting pieces 263 are fixedly installed on both sides of one end of the cooling plate 262. The two sides of the connecting pieces 263 are respectively fixedly installed on one side of the air box 21 and one side of the thermoelectric cooler 23. The connecting pieces 263, the cooling plate 262, and the cooling bracket 261 are all made of copper. By setting the connecting pieces 263, the connection area between the cooling plate 262 and the thermoelectric cooler 23 can be increased, allowing it to cool quickly and conduct the temperature to the cooling bracket 261, thus accelerating the cooling effect.

[0031] Working Principle: In the production and processing of ultrapure water, water is first introduced through the inlet of coarse filter 4. Coarse filter 4 initially filters out large particles of impurities. The water passing through coarse filter 4 is then transported along the pipeline to reverse osmosis unit 6. Inside reverse osmosis unit 6, the reverse osmosis membrane removes larger organic particles, bacteria, and viruses from the water. The water treated by reverse osmosis unit 6 enters ion exchange unit 7, where it undergoes an ion exchange reaction with the water to remove dissolved salts. The water treated by ion exchange unit 7 then enters ultrafiltration unit 5. Ultrafiltration unit 5 uses a membrane to screen out colloids, suspended solids, bacteria, viruses, and large molecular organic matter from the water. The water treated by ultrafiltration unit 5 meets the ultrapure water standard and is discharged. The equipment is equipped with control... Box 3 is responsible for real-time monitoring of water quality parameters, adjusting the filtration process, and controlling the operation of water pumps and valves. It is the "nerve center" that ensures the stable and efficient operation of the ultrapure water filtration process. When the control box 3 is in use, the semiconductor cooling chip 23 can be connected to the power supply, and then the air pump 22 can be started to draw air into the air box 21, so that it comes into contact with the inside of the air box 21 to exchange heat and reduce the temperature. Then it flows into the guide pipe 24 and is sprayed into the inside of the control box 3 through the nozzle frame 25, so that it exchanges heat with the hot air inside the control box 3. The hot air is actively discharged from the heat dissipation holes to achieve a rapid cooling effect, so as to avoid the internal temperature of the control box 3 being too high and affecting the normal operation of electrical equipment, thus improving the service life of the internal equipment of the control box 3 and avoiding affecting the processing of ultrapure water. When the semiconductor cooling chip 23 cools the surface of the air box 21, it also cools the temperature of the heat-conducting chip 262, which is then conducted to the heat-conducting frame 261. The heat exchange occurs through the contact between the heat-conducting frame 261 and the inner wall of the control box 3, thus reducing the temperature. Therefore, the cooling effect can be enhanced, making it less likely for the inside of the control box 3 to overheat and be damaged.

[0032] It should be noted that:

[0033] Coarse filter 4 can use activated carbon and other materials to adsorb and intercept large particulate impurities in the water;

[0034] Reverse osmosis (RO) units utilize the selective permeability of a semi-permeable membrane (pore size of approximately 0.0001 micrometers) to allow water molecules to pass through under high pressure (1-10 MPa), while retaining all dissolved salts, organic matter, bacteria, and viruses.

[0035] Ion exchange components (IE) remove dissolved salts by exchanging ions with the functional groups of ion exchange resins (such as cation exchange resins and anion exchange resins).

[0036] Ultrafiltration (UF) devices utilize the sieving effect of membrane pores (0.01-0.1 micrometers) to retain colloids, suspended solids, bacteria, viruses, and large organic molecules. These are all existing conventional technologies and will not be elaborated upon here.

[0037] Water in the coarse filter 4, ultrafiltration unit 5, reverse osmosis unit 6, and ion exchange unit 7 can be transported by external pressure or by a water pump; this application does not make specific limitations here.

[0038] All components of the equipment in this application are regularly maintained and inspected by staff, and the replacement of consumables after wear and tear is within the scope of maintenance and inspection.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
