Description

Technical Field

[0001] The utility model relates to purification equipment, in particular to tail gas purification equipment used in etching liquid production, belonging to the technical field of etching liquid. Background Art

[0002] Etching liquid is a raw material for copperplate engraving, and is a liquid that erodes the material's characteristics for engraving. Theoretically, any reagent that can oxidize copper to generate soluble copper salts can be used to etch copper-clad boards, but the damage to the anti-etching layer, etching speed, etching coefficient, copper dissolving capacity, solution regeneration and copper recovery, environmental protection and economic effects must be weighed.

[0003] The use of etching liquid in the production process will produce tail gas containing corrosive, harmful and toxic components, such as hydrogen fluoride, nitric acid vapor and other volatile organic compounds. If these tail gases are directly discharged without proper treatment, they will pollute the environment and cause harm to human health. Therefore, purification equipment will be used to treat the tail gas, remove harmful substances and reduce environmental pollution;

[0004] When filtering the exhaust gas, harmful substances will be adsorbed on the surface of the filter in the purification equipment. Therefore, ensuring that the etching liquid exhaust filter can be easily disassembled and replaced is an important measure to maintain the normal operation of the exhaust system and ensure workplace safety. However, the filter in the prior art may not be convenient to install and disassemble. If the filter is cumbersome to disassemble, the filtration efficiency will drop significantly as the filter material becomes clogged, resulting in the inability to effectively remove harmful gases, increasing health risks and environmental pollution in the working environment. Secondly, the increased resistance of the filter may cause the exhaust system to load heavier, increase energy consumption and equipment maintenance costs. At the same time, if it is not replaced regularly, the chemicals accumulated on the filter may cause corrosion and damage, and may even cause safety accidents, such as chemical leaks or fires.

[0005] Therefore, a tail gas purification device for etching liquid production is proposed. Utility Model Content

[0029] By setting up the disassembly mechanism 6, it is convenient for operators to install and disassemble the filter 8, thereby simplifying the maintenance process, reducing maintenance costs and time, and ensuring continuous compliance with filtering efficiency and safety standards. It also helps to regularly replace and clean the filter 8, avoid the risks caused by clogging of the filter medium, and extend the service life of the entire purification system. In addition, it is also convenient to regularly check the filter and quickly identify potential damage or corrosion problems, thereby reducing the possibility of sudden failures and ensuring that exhaust emissions always comply with environmental protection regulations, thereby maintaining the health and safety of the workplace and the environment.

[0030] Example 2

[0031] In one embodiment, a card slot 613 is opened on the inner side of the installation box 608, the front end of the filter screen 8 is clamped on the inner side of the card slot 613, a positioning hole 9 is opened on the surface of the filter screen 8, the insertion rod 612 extends to the inner side of the positioning hole 9, and the left and right sides of the filter screen 8 are fixedly installed with a fixing plate 10, the positioning rod 607 extends to the inner side of the fixing plate 10, and the through groove 614 is opened on the left and right sides of the rear side of the shell 1. The fixing plate 10 passes through the through groove 614 and extends into the inner cavity of the connection box 2. The left and right sides of the inner cavity of the shell 1 are fixedly installed with a guide block 11, and the filter screen 8 is slidably connected to the inner side of the guide block 11.

[0032] By setting the positioning hole 9 and the fixing plate 10, the filter screen 8 can be conveniently fixed after installation, thereby preventing the filter screen 8 from falling off during operation. The setting of the guide block 11 can play a guiding role to avoid the filter screen 8 from shifting during installation. The setting of the through groove 614 can improve the stability of the fixing plate 10 during installation.

[0033] When the utility model is working: after the fan 4 is started, the air flows, the exhaust gas flows into the inner cavity of the shell 1 through the bellows 3, is filtered by the filter 8, and is transported out from the vent 5, thereby completing the purification. When the filter 8 needs to be replaced, the knob 615 can be manually turned to drive the rotating rod 602 and the transmission gear 603 to rotate. When the transmission gear 603 rotates, the driven gear 604 is driven to rotate through the meshing of the teeth, thereby driving the bidirectional screw 601 to rotate. During the rotation of the bidirectional screw 601, the threaded connection is used. The connecting plate 606 is driven to move inward, thereby making the connecting plate 606 move inward, driving the positioning rod 607 to separate from the inner side of the fixing plate 10. At this time, pulling the cover plate 7 outward can drive the filter screen 8 to move outward. When the filter screen 8 is separated from the inner cavity of the shell 1, the connecting rod 610 is pulled outward, thereby driving the partition plate 609 to move outward. When the partition plate 609 moves outward, it will drive the insertion rod 612 to separate from the inner side of the positioning hole 9, thereby releasing the fixation of the filter screen 8, completing the disassembly of the filter screen 8, and facilitating subsequent cleaning or replacement operations.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
