Description

Technical Field

[0001] The utility model relates to the technical field of liquid filtration, in particular to a sodium carbonate solution fine filtration device. Background Art

[0002] A sodium carbonate solution fine filtration device is mainly used for fine filtration of sodium carbonate solution to remove impurities and improve the purity of the solution. In the chemical industry, sodium carbonate is an important raw material or intermediate product. The fine filtration device can be used to purify the sodium carbonate solution to meet the requirements of downstream chemical reactions for raw material purity. Sodium carbonate solution is also commonly used as a cleaning agent, especially in the metal processing industry. The fine filtration device can ensure the purity of the cleaning solution and improve the cleaning effect. This fine filtration device can remove impurities such as suspended matter, organic matter, and microorganisms in the solution through a multi-stage filtration system, thereby improving the quality of the sodium carbonate solution and ensuring its performance and effect in various applications;

[0003] When using the existing sodium carbonate solution fine filtration device, the fine filtration device is placed on a stable horizontal surface to pre-treat the sodium carbonate solution and filter out large particles of impurities to reduce clogging and wear of the filter screen. The solution is allowed to pass through the filter screen and the fine filtration membrane through the filtration device to separate solid particles and impurities.

[0004] The disadvantage of the above solution is that: when the above solution is used, since the pore size of the fine filter membrane is usually smaller than that of the filter mesh, it can intercept smaller particles. However, in the absence of external pressure, the flow of the solution mainly depends on gravity and capillary action. In this case, the filtration speed will be relatively slow, and the solid particles in the solution are more likely to deposit on the filter medium, which may lead to technical problems such as reduced filtration efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a sodium carbonate solution fine filtration device to solve the technical problems in the prior art that, in the absence of external pressure, the flow of the solution mainly depends on gravity and capillary action. In this case, the filtration speed will be relatively slow, and the solid particles in the solution are more likely to be deposited on the filter medium, which may lead to a decrease in filtration efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 3 As shown, a sodium carbonate solution fine filtration device includes a filter box 1, a liquid inlet 2 is provided on the top of the filter box 1, a filter screen 3 is provided inside the filter box 1, and a fine filtration mechanism is provided below the filter screen 3;

[0026] The fine filtration mechanism includes an adsorption membrane plate 14 and a filter membrane plate 16, wherein the adsorption membrane plate 14 is an activated carbon membrane and the filter membrane plate 16 is a semipermeable membrane. The adsorption membrane plate 14 and the filter membrane plate 16 are both arranged inside the filter box 1, and a chute 15 is connected to the side wall of the filter box 1. The adsorption membrane plate 14 and the filter membrane plate 16 are connected to a connecting plate 17, and a handle is connected to the connecting plate 17;

[0027] A pulling mechanism is connected between the fine filtering mechanism and the filter screen 3, and the pulling mechanism includes a plug-in board 4 and a plug-in board 2 5. The plug-in board 1 4 and the plug-in board 2 5 are both arranged inside the filter box 1, and the plug-in board 2 5 is plugged into the plug-in board 1 4. A slide bar 1 8 is connected to the plug-in board 1 4, and a slide bar 2 9 is connected to the plug-in board 2 5. A magnetic attraction mechanism is provided between the plug-in board 1 4 and the plug-in board 2 5, and the magnetic attraction mechanism includes a magnet 1 6 and a magnet 2 7. The magnet 1 6 is connected to the end of the plug-in board 2 5, and the magnet 2 7 is connected to the end of the plug-in board 1 4;

[0028] The pulling mechanism is connected to a slider 10, and a sliding groove is provided on the side of the filter box 1. The slide bar 1 8 and the slide bar 2 10 can slide on the sliding groove, and a sealing ring is connected to the side of the sliding groove. The two slide bars 10 are connected to a pressing mechanism, and the pressing mechanism includes two fixed blocks 11 and a slide bar 3 12. The two fixed blocks 11 are connected to the filter box 1, and the two slide bars 3 12 are slidably connected in the fixed block 11. The ends of the two slide bars 3 12 away from the slider 10 are commonly connected to a pressing rod 13 through a rod body;

[0029] A liquid suction pump 18 is connected to the bottom of the filter box 1 , and an end of the liquid suction pump 18 away from the filter box 1 is connected to a liquid collecting box 19 .

[0030] The working principle of the present invention is as follows: first, the sodium carbonate solution enters the filter box 1 through the liquid inlet 2 at the top, and the solution first flows through the filter screen 3. The function of the filter screen 3 is to initially intercept larger particles and suspended matter to prevent them from entering the subsequent fine filtration mechanism. The solution after preliminary filtration continues to flow to the fine filtration mechanism below, and the adsorption membrane plate 14 adsorbs organic pollutants and certain metal ions in the solution through its porous structure and surface active sites, while the semi-permeable membrane filter membrane plate 16 further removes particles and suspended matter in the solution through its semi-permeability. In order to ensure that the solution passes through the adsorption membrane plate 14 and the filter membrane plate 16, the plug-in board 2 5 is plugged into the plug-in board 1 4, and the plug-in board 2 5 and the plug-in board 1 4 are fixed by the attraction of the magnetic attraction mechanism (magnet 1 6 and magnet 2 7). By pressing the pressure rod 13, the pressure rod 13 drives the slide bar 3 12 to slide in the fixed block 11, pushing the slide bar 1 8 and the slide bar 2 9 downward to squeeze the sodium carbonate solution until the sodium carbonate solution passes through the adsorption membrane plate 14 and the filter membrane plate 16.

[0031] The filtered clean solution is pumped out through the suction pump 18 at the bottom of the filter box 1 and then transported to the liquid collection tank 19 for collection or further processing. During the whole process, the design of the fine filter ensures that the solution can effectively remove impurities and pollutants when passing through multiple filter layers, ensuring the continuity of the filtering effect and the convenience of operation.

[0032] The above describes an embodiment of the present invention in detail. However, the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
