Description

Technical Field

[0001] The utility model relates to the field of pressure conveying devices, in particular to a pressure conveying device for a perfluorosulfonic acid resin membrane solution. Background Art

[0002] Since the perfluorosulfonic acid resin membrane solution is highly acidic and corrosive, and the proton exchange membrane strictly controls metal ions, the material of the conveying system is very demanding when storing and conveying the perfluorosulfonic acid resin membrane solution. In the prior art, in order to ensure the thickness stability of the coating, a gear pump is generally used to convey the perfluorosulfonic acid resin membrane solution. The gear pump is generally made of metal, which is easily corroded by the highly corrosive membrane solution, causing the membrane solution itself to be contaminated by metal ions during transportation. Of course, there are also some gear pumps made of PEEK material, but it cannot be ensured that the parts in contact with the membrane solution are all made of PEEK material, which can easily lead to the risk of contamination of the perfluorosulfonic acid resin membrane solution. In addition, the PEEK material itself is also easy to wear and thus contaminate the perfluorosulfonic acid resin membrane solution. The cost of PEEK gear pumps is relatively high, so its maintenance and replacement costs are also high.

[0003] Therefore, it is necessary to focus on how to reduce the risk of contamination of the perfluorosulfonic acid resin membrane solution by metals and other materials during storage and transportation, and ensure the transportation stability of the perfluorosulfonic acid resin membrane solution.

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The perfluorosulfonic acid resin membrane solution pressure delivery device comprises a base 1, and fixing rods 2 are respectively arranged on both sides of the base 1, and limiting grooves 201 are provided on the upper ends of the opposite surfaces of the two fixing rods 2. The two limiting grooves 201 cooperate to accommodate the solution pressure storage tank 3 and limit it. The operator can select the depth of the limiting groove according to actual needs.

[0022] A lifting cylinder 4 is provided below the solution pressure storage tank 3, and the lifting cylinder 4 is used to cooperate with the aforementioned limiting groove 201 to further adjust the position of the solution pressure storage tank 3. Of course, in order to realize the lifting and lowering action of the solution pressure storage tank 3, it is not limited to using the lifting cylinder 4 to drive, and a hydraulic cylinder or a screw lift can also be used to drive the solution pressure storage tank 3 to lift and lower.

[0023] In the utility model, a controller 5 is also provided in the pressure conveying device of the pressure perfluorosulfonic acid resin membrane solution, and the output end of the controller 5 is electrically connected to the input end of the lifting cylinder 4. In actual operation, the controller 5 transmits a lifting signal to the lifting cylinder 4, and the lifting cylinder 4 performs lifting work after receiving the lifting signal.

[0024] A liquid outlet 301 and an air inlet 302 are provided on the top of the tank body of the solution pressure storage tank 3 .

[0025] One end of the liquid outlet 301 is connected to the external liquid collecting mechanism, and the other end is connected to the liquid container 303 in the solution pressure storage tank 3 through the liquid outlet pipe. The liquid outlet pipe is made of Teflon material, and the pipe made of Teflon material has strong corrosion resistance and will not pollute the liquid.

[0026] The air inlet 302 is connected to an external pressure delivery mechanism through a gas delivery pipeline. A stop valve (not shown in the figure) is also provided on the gas delivery pipeline. The input end of the stop valve is connected to the output end of the aforementioned controller 5 for controlling the start and stop of the air intake action.

[0027] An air inlet cavity 304 with a certain space size is arranged above the liquid container 303, and the size of the air inlet cavity 304 can also be determined according to the size of the hydraulic parameters actually required. The air inlet hole 302 introduces the pressure provided by the external pressure delivery mechanism into the air inlet cavity 304, and then transmits it to the liquid container 303, more specifically, to the liquid in the liquid container 303. When the liquid is subjected to the pressure of the external gas, the liquid level will automatically rise, and part of the liquid will be transported to the external liquid collection mechanism along the liquid outlet pipe.

[0028] A concave bushing 305 is also sleeved on the outer periphery of the liquid container 303, and the opening diameter of the concave bushing 305 can be larger than the outer diameter of the liquid container 303, or can be consistent with the outer diameter of the liquid container 303. The provision of the concave bushing 305 can fix the liquid container 303, and prevent the liquid container 303 from tipping over during the operation of the lifting cylinder 4, thereby contaminating the interior of the solution pressure storage tank 3 and affecting the infusion effect.

[0029] At the same time, a liquid level meter 306 is also provided in the liquid container 303. The liquid level meter 306 is used to monitor the real-time liquid level in the container. The output end of the liquid level meter 306 is electrically connected to the input end of the controller 5. As a preferred embodiment, a liquid level alarm can also be provided in the liquid container 303. When the real-time liquid level in the container is lower than the liquid level warning value, the liquid level alarm automatically alarms.

[0030] In addition, when the gas is stopped from being introduced into the solution pressure storage tank 3, the liquid in the liquid container 303 will automatically fall back after a period of time, and the liquid level at this time will be lower than the liquid level before the gas is introduced. The lowered liquid level difference is compensated by the lifting action of the lifting cylinder 4. By inputting the liquid level difference at the controller 5, and then transmitting the difference signal to the lifting cylinder 4, the lifting cylinder 4 will lift a certain liquid level difference height upward. It can be understood that the lifting cylinder 4 will rise by the same height as the liquid level in the liquid container 303 drops, so as to ensure that the liquid outlet pipe can penetrate into the bottom of the liquid container 303, avoid the situation of empty liquid extraction during the transportation process, and avoid the extraction of bubbles.

[0031] In summary, the utility model is a perfluorosulfonic acid resin membrane solution pressure conveying device, which uses compressed air to hydraulically convey the perfluorosulfonic acid resin membrane solution, thereby avoiding contact corrosion between the membrane solution and the conveying components during the conveying process, reducing the risk of the membrane solution being contaminated during the conveying process, and ensuring the stability of the membrane solution during the conveying process.

[0032] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
