Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water treatment technology, specifically relating to a demineralized water tank. Background Technology
[0002] Desalinated water refers to water that has undergone a series of water treatment processes (such as reverse osmosis, ion exchange, and electro-desalination) to remove most of the dissolved salts and impurities, thus achieving high purity.
[0003] Demineralized water tanks are used to store demineralized water. To prevent suspended particles, dust, and other substances in the air from entering the demineralized water tank and contaminating it, causing the water quality to exceed standards, the demineralized water tank is usually sealed. However, the actual problem is that when the water in the demineralized water tank is pumped out for use, the pressure inside the sealed demineralized water tank decreases. Under the action of external atmospheric pressure, the tank body is easily crushed and deformed. Utility Model Content
[0004] This application proposes a demineralized water tank, which is used to replenish gas into the demineralized water tank when water is pumped out of the water tank, so as to achieve pressure balance inside and outside the water tank and avoid excessive pressure difference between the inside and outside of the water tank, which would cause the water tank to deform.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A demineralized water tank includes a tank body with a sealing cover on the upper part. A first air pipe is provided on the upper part of the tank body, one end of which is connected to the inside of the tank body, and the other end of which is connected to the upper part of a first cavity. The lower part of the side wall of the first cavity is connected to one end of a second air pipe. A fan is installed on the second air pipe, and a filter screen is provided on the other end of the second air pipe. A first drain pipe is provided on the side wall of the tank body. A pressure sensor is installed on the top wall of the tank body. The pressure sensor is electrically connected to a controller, and the controller is electrically connected to the fan.
[0007] In one embodiment of this application, a fixing frame is provided at the top of the second trachea, and a filter screen is provided in the through hole on the side wall of the fixing frame.
[0008] In one embodiment of this application, the second air pipe is connected to an exhaust pipe in the first cavity, and the exhaust pipe is provided with a plurality of exhaust holes.
[0009] In one embodiment of this application, a liquid exchange port is provided at the upper part of the first cavity.
[0010] In one embodiment of this application, a second drain pipe is provided at the bottom of the box, and a support is provided at the bottom of the box.
[0011] In one embodiment of this application, a drainage ramp is provided on the bottom surface inside the box.
[0012] In one embodiment of this application, a liquid level pipe is provided on the side wall of the tank, and the two ends of the liquid level pipe are connected to the inside of the tank.
[0013] In summary, the technical solution proposed in this application includes the following beneficial technical effects: the fan introduces air into the first cavity through the second air pipe. The air outlet of the second air pipe is located below the liquid surface of the first cavity. When the air comes out from the air outlet, it comes into contact with the solution in the first cavity in the form of bubbles. During the contact between the air and the liquid, the impurity particles are adsorbed and captured by the liquid and remain in the liquid to achieve purification. The purified air is then replenished into the tank through the first air pipe to achieve pressure balance inside and outside the water tank, avoiding excessive pressure difference between the inside and outside of the water tank, which could cause the water tank to deform. Purifying the injected gas can prevent the demineralized water in the water tank from being contaminated by impurities, which is beneficial to improving the purity of the demineralized water in the tank.

[0026] This embodiment provides a demineralized water tank, see reference. Figures 1-5 As shown, the device includes a housing 1, with a sealing cover 11 on the upper part of the housing 1. A first air pipe 12 is provided on the upper part of the housing 1, with one end of the first air pipe 12 connected to the inside of the housing 1 and the other end of the first air pipe 12 connected to the upper part of a first cavity 2. The lower part of the side wall of the first cavity 2 is connected to one end of a second air pipe 21, with a fan 211 installed on the second air pipe 21 and a filter screen provided at the other end of the second air pipe 21. A first drain pipe 13 is provided on the side wall of the housing 1, and a pressure sensor is installed on the top wall inside the housing 1. The pressure sensor is electrically connected to a controller, and the controller is electrically connected to the fan 211.
[0027] In the above embodiment, a sealing cover 11 is provided on the upper part of the box 1. The sealing cover 11 is opened to add demineralized water into the box 1. A first air pipe 12 is provided on the upper part of the box 1. One end of the first air pipe 12 is connected to the inside of the box 1, and the other end of the first air pipe 12 is connected to the upper part of the first cavity 2. Liquid, such as water, is added into the first cavity 2. The liquid level in the first cavity 2 is controlled below the air port of the first air pipe 12. The lower part of the side wall of the first cavity 2 is connected to one end of the second air pipe 21. The second air pipe 21 is vertically arranged, that is, the air port of the second air pipe 21 is located below the liquid level of the first cavity 2. The liquid is in a liquid-sealed state to the air port of the second air pipe 21, so that the second air pipe 21 and the first air pipe 12 are not directly connected, which is beneficial to improving the airtightness of the box 1. Furthermore, a fan 211 is installed on the second air pipe 21, and a filter screen is provided at the other end of the second air pipe 21 for preliminary filtration of the air entering the second air pipe 21. A pressure sensor is installed on the top wall inside the housing 1, and the pressure sensor is electrically connected to the controller. The controller is electrically connected to the fan 211. In the initial state, the air pressure inside the housing 1 is the same as the external air pressure. When the demineralized water in the water tank is discharged through the first drain pipe 13, the air pressure inside the water tank decreases. The pressure sensor is used to convert the air pressure value inside the water tank into an electrical signal and transmit it to the controller. The controller can be an existing microcontroller (MCU) or PLC, etc. When the controller determines that the air pressure value is lower than the external average air pressure value, such as the standard air pressure of 101.325 kPa, the controller... The controller starts the fan 211 and introduces air into the first chamber 2 through the second air pipe 21. The air inlet of the second air pipe 21 is located below the liquid surface in the first chamber 2. When the air comes out of the air inlet, it comes into contact with the solution in the first chamber 2 in the form of bubbles. During the contact between the air and the liquid, the impurity particles are captured and retained in the liquid, thus achieving purification. The purified air is then introduced into the tank 1 through the first air pipe 12. When the air pressure in the tank 1 rises to the average air pressure value, the controller stops the fan 211, thereby achieving pressure balance inside and outside the water tank and avoiding excessive pressure difference that could cause the water tank to deform. In addition, purifying the injected gas can prevent the demineralized water in the water tank from being contaminated by impurities, which is beneficial to improving the purity of the demineralized water in the tank 1.
[0028] In one embodiment of this application, see reference Figure 1 and Figure 2 As shown, a fixing frame 212 is provided at the top of the second air tube 21, and a filter screen is provided in the through hole on the side wall of the fixing frame 212.
[0029] In the above embodiment, filter screens are respectively provided at the through holes on multiple sides of the fixing frame 212. The fixing frame 212 can be used to support the filter bag, increase the cross-sectional area of air flow filtration, and improve the smoothness of air entering the second air pipe 21.
[0030] In one embodiment of this application, see [reference] Figure 2 As shown, the second air pipe 21 is connected to the exhaust pipe 22 in the first cavity 2, and the exhaust pipe 22 is provided with multiple exhaust holes.
[0031] In the above embodiment, the exhaust pipe 22 is located below the liquid surface in the first cavity 2. The air in the second air pipe 21 is discharged through multiple exhaust holes on the exhaust pipe 22. Compared with the second air pipe 21 directly discharging air below the liquid surface in the first cavity 2, the size of the discharged bubbles can be reduced, allowing the bubbles to fully contact the liquid, which is beneficial to improving the air purification efficiency.
[0032] In one embodiment of this application, see reference Figure 5 As shown, the upper part of the first cavity 2 is provided with a liquid exchange port 23.
[0033] In the above embodiment, when the water tank is being cleaned and maintained, the liquid in the first chamber 2 can be drawn and replaced through the liquid replacement port 23. Regularly replacing the liquid in the first chamber 2 is beneficial to improving the liquid's purification effect on the air. When the water tank is in use, the liquid replacement port 23 is covered with a cover plate to seal the liquid replacement port 23.
[0034] In one embodiment of this application, see reference Figure 4 As shown, a second drain pipe 14 is provided at the bottom of the box body 1, and a support 15 is provided at the bottom of the box body 1.
[0035] In the above embodiment, a second drain pipe 14 is provided at the bottom of the tank 1 to drain the residual water in the tank 1 when cleaning and maintaining the water tank, which is beneficial to improving the cleaning efficiency of the water tank. The support 15 at the bottom of the tank 1 is used to lift the tank 1 off the ground to facilitate the installation and drainage of the second drain pipe 14.
[0036] In one embodiment of this application, see reference Figure 3 As shown, the bottom surface inside the box 1 is provided with a flow-guiding slope 16.
[0037] In the above embodiment, a drain outlet is provided at the center low point of the drainage slope 16. The drain outlet is connected to the second drain pipe 14. The drainage slope 16 is used to drain the residual liquid at the bottom of the tank 1 through the slope to the drain outlet for discharge when draining liquid in the tank 1, so as to prevent liquid residue in the tank 1 from causing pollution inside the tank 1.
[0038] In one embodiment of this application, see reference Figure 4 As shown, a liquid level pipe 17 is provided on the side wall of the box 1, and both ends of the liquid level pipe 17 are connected to the inside of the box 1.
[0039] In the above embodiment, the two ends of the liquid level tube 17 are connected to the inside of the tank 1, so that the water level inside the liquid level tube 17 is consistent with the water level inside the water tank. The liquid level tube 17 is set vertically and is made of a transparent material, such as tempered glass, so as to facilitate observation of the amount of demineralized water used in the water tank and timely replenishment of demineralized water in the water tank.
[0040] In actual use, the following is observed: a sealing cover 11 is provided on the upper part of the tank 1. Opening the sealing cover 11 allows for the addition of demineralized water into the tank 1. A first drain pipe 13 is provided on the side wall of the tank 1 to discharge the demineralized water from the tank 1 for use. A pressure sensor is installed on the top wall inside the tank 1, and the pressure sensor is electrically connected to the controller. The controller is electrically connected to the fan 211. Initially, the pressure inside the tank 1 is the same as the external pressure. When the demineralized water in the tank is discharged through the first drain pipe 13, the pressure inside the tank decreases. The pressure sensor converts the pressure value inside the tank into an electrical signal and transmits it to the controller. Existing microcontrollers (MCUs) or PLCs can be used. When the controller determines that the air pressure is lower than the average external air pressure, such as 101.325 kPa, the controller controls the fan 211 to start and introduce air into the first chamber 2 through the second air pipe 21. The air inlet of the second air pipe 21 is located below the liquid surface in the first chamber 2. When the air comes out of the air inlet, it comes into contact with the solution in the first chamber 2 in the form of bubbles. During the process of contact between the air impurities and the liquid, they will be adsorbed and captured by the liquid and retained in the liquid to achieve purification. The purified air is then replenished into the tank 1 through the first air pipe 12 to achieve pressure balance inside and outside the water tank.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
