[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] This invention provides a precision heavy ion microporous membrane etching processing tank. The etching tank is equipped with screw lifting adjustment devices on both sides. During material replacement and feeding, the screw motors on both sides can be directly activated to quickly pull the entire drive shaft frame out of the liquid surface, enabling rapid material feeding and maintenance, reducing the time spent on material feeding, maintenance, and replacement. A filter device is added to one side, with a pump drawing out impurities and mixtures from the liquid, which are then filtered through a filter screen to completely separate the liquid from the impurities, improving production quality. (See also...) Figs. 1-3It includes: etching tank 1, sodium hydroxide solution 2, drive shaft frame 3, membrane material 4, drive shaft 5, bearing frame retainer 6, upper and lower screw motors 7, screw rod 8, motor platform 9, bearing fixing lock 10, filter device inlet pipe 11, filter device 12, filter device pump 13, filter device outlet pipe 14, and filter screen 15.

[0023] Sodium hydroxide solution 2 is added inside the etching tank 1. Motor platforms 9 are set on both the left and right side walls of the etching tank 1. Screw motors 7 are set on the motor platforms 9. Screw rods 8 are connected to the screw motors 7. A drive shaft bracket 3 is set on the upper part of the screw rod 8. A bearing fixing buckle 10 is set on the drive shaft bracket 3. A drive shaft 5 is set on the bearing fixing buckle 10. Membrane material 4 is connected between the drive shafts 5. A bearing bracket retainer 6 is set at the bottom of the etching tank 1. A filter device 12 is set on the side wall of the etching tank 1. The filter device 12 is connected to the inner cavity of the etching tank 1 through a filter device inlet pipe 11. A filter device outlet pipe 14 is set at the bottom of the filter device 12, which is connected to the inner cavity of the etching tank 1. A filter device pump 13 is set on the filter device outlet pipe 14. A filter screen 15 is set inside the filter device 12.

[0024] To ensure effective extraction of sodium hydroxide solution 2, the inlet pipe 11 of the filter device is lower than the surface of the sodium hydroxide solution 2, and the filter screen 15 is located at the bottom of the inner cavity of the filter device 12, so that the sodium hydroxide solution 2 on the surface can be extracted and discharged after being filtered by the filter screen 15.

[0025] To prevent structural corrosion and extend service life, the outlet pipe 14 of the filter device is connected to the pump 13 of the filter device using a PPR pipe, and the filter screen 15 is made of stainless steel mesh.

[0026] To ensure the transmission effect of the membrane material 4, the transmission shafts 5 are arranged in parallel to each other, and the transmission shafts 5 are evenly and staggered on the transmission shaft frame 3.

[0027] Specifically, firstly, the etching tank 1 is made into a cuboid shape to reduce the internal height of the etching tank. Since the etching tank 1 contains a high-temperature, corrosive liquid, there is a safety risk for personnel entering. Reducing the depth can effectively avoid this safety risk. Six fixed corners are made at the four corners and the middle of the bottom of the etching tank 1 as bearing bracket holders 6. The fixed corners are parallel and perpendicular to each other, which facilitates the subsequent fixing of the drive shaft bracket 3 and makes the installation simple and quick.

[0028] Secondly, the transmission shaft part of etching tank 1 is made into a transmission shaft bracket 3. The bearing bracket 3 is equipped with a fixing buckle 10 for mounting the shaft. The installed shafts should be evenly spaced, parallel and perpendicular to each other. The etching tank 1 is equipped with a screw lifting adjustment device on both sides. When changing and feeding materials, the screw motors on both sides can be directly turned on to quickly pull the entire transmission shaft bracket out of the liquid surface, which can quickly feed materials and perform maintenance, reducing the time for feeding materials and maintenance replacement.

[0029] Thirdly, impurities are generated during the etching process of the etched film. When the chemical solution (sodium hydroxide solution) cools, it will clump together. If not cleaned in time, it will adhere to the drive shaft 5, causing the film to break or the filter screen to become clogged. By adding a filter device 12 on one side, a self-priming pump is used to draw out the impurity mixture in the liquid and filter it through the filter screen, so that the liquid and impurities are completely separated, thus improving the production quality.

[0030] Specifically, etching tank 1 is a cuboid, and the length can be selected according to requirements. The internal width is 0.6 meters to facilitate the installation of the drive shaft bracket 3. The internal depth should be 0.4 meters to allow for simple maintenance while wearing high-temperature alkali-resistant gloves. The four corners and the middle fixing corner need to be designed as quick-release buckles so that they can be quickly removed and automatically locked when put back.

[0031] The drive shaft bracket 3 is used to fix the drive shaft 5. The bearing fixing locks 10 are evenly distributed to ensure that each shaft is parallel and perpendicular to each other, and the distance between each shaft is also equal.

[0032] The drive shaft frame 3 is lifted and lowered by a screw motor, which allows for quick and convenient maintenance and material loading, improving production efficiency and ensuring safe production.

[0033] The filter device 12 is a rectangular box with a side length consistent with the width of the etching tank and a height of 0.2 meters. It is connected to the pump body via a PPR pipe at the bottom and uses a self-priming pump to transfer liquid. The filter screen 15 is made of stainless steel.

[0034] The installation steps are as follows:

[0035] The length, width, and height of the etching tank 1 are customized according to requirements, and the depth is reduced. Bearing bracket retainers 6 are installed at the four corners and the middle position, for a total of 6, to facilitate the subsequent installation of the drive shaft bracket.

[0036] Install the drive shaft bracket 3, ensuring the gap between each shaft and that each shaft is parallel and perpendicular. Install the bearing fixing lock 10 for subsequent shaft installation. Install the hoisting equipment on the upper part of the etching tank 1 for subsequent hoisting of the drive shaft bracket 3.

[0037] The filter device 12 should be installed at the edge of the etching tank 1. First install the filter device 12, then install the self-priming pump and use the self-priming pump to transfer the liquid for filtration.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
