Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A high-purity gas generator purification and filtration device includes a positioning base plate 1. A gas generator body 2 is fixedly connected to the top of the positioning base plate 1. An air inlet pipe 3 is fixedly connected to the top of the gas generator body 2. A housing 4 is provided on one side of the gas generator body 2. The housing 4 is fixedly installed on the top of the positioning base plate 1. A filter chamber 5 is reserved inside the housing 4. A delivery pipe 6 is fixedly embedded in the side wall of the housing 4. One end of the delivery pipe 6 passes through the housing 4. Three sets of filter cartridges 7 are arranged inside the filter chamber 5. The three sets of filter cartridges 7 are connected sequentially through a bend pipe 18. The interface of the bend pipe 18 is connected by a flange. Three sets of support components 8 are provided on one inner wall for positioning the filter cartridge 7. By using the housing 4, filter chamber 5, delivery pipe 6, filter cartridge 7, bend 18 and support components 8 together, the gas generated by the gas generator body 2 can be filtered through the filter cartridge 7 inside the filter chamber 5. Moreover, each filter cartridge 7 can be disassembled and replaced individually, which is simple and quick to operate. The support components 8 play a role in assisting the positioning of the filter cartridge 7, preventing it from shifting during use, which helps to further improve the stability of the device.

[0025] Specifically, the support assembly 8 includes a connecting frame 801. One side of the connecting frame 801 is fixedly connected to the inner wall of one side of the filter chamber 5. The other side of the connecting frame 801 is provided with a slot 802 that is adapted to the filter cartridge 7. The filter cartridge 7 is snapped into the inside of the slot 802. When it is necessary to disassemble a single filter cartridge 7, simply remove the flanges at the top and bottom, and then directly remove the filter cartridge 7 from the inside of the slot 802.

[0026] Furthermore, three sets of limiting holes 9 are provided on one inner wall of the slot 802, and three sets of limiting posts 10 that are compatible with the limiting holes 9 are fixedly connected to the outer wall of the filter cartridge 7. The three sets of limiting posts 10 are respectively inserted into the three sets of limiting holes 9. By setting the limiting holes 9 and the limiting posts 10 in cooperation, the filter cartridge 7 is limited. When the filter cartridge 7 needs to be installed, it is only necessary to insert the limiting post 10 on one side into the limiting hole 9, and then connect the top and bottom interfaces to the corresponding pipes through flanges.

[0027] Furthermore, an opening 11 is provided on one side wall of the housing 4, and a cover plate 12 is connected to the housing 4 on one side of the opening 11 via a hinge. A lock is provided on one side wall of the cover plate 12, and the staff can disassemble and maintain the corresponding filter cartridge 7 by opening the cover plate 12 and through the opening 11.

[0028] It is worth noting that three sets of protrusions 13 are fixedly connected to one side wall of the cover plate 12. The tops of the three sets of protrusions 13 abut against the bottoms of the three sets of filter cartridges 7 respectively. After the corresponding filter cartridges 7 are maintained and the cover plate 12 is closed to the housing 4, the three sets of protrusions 13 on one side of the cover plate 12 can be located inside the three sets of filter cartridges 7 respectively, thereby providing further support and positioning for the filter cartridges 7 and greatly improving their stability in use.

[0029] Furthermore, a through hole 14 is provided on one side wall of the housing 4, and an air outlet pipe 15 is fixedly embedded inside the through hole 14. One end of the air outlet pipe 15 is fixedly connected to the bottom of one set of filter cartridges 7 through a flange. By setting the through hole 14, the air outlet pipe 15 is installed and positioned.

[0030] Furthermore, a mounting hole 16 adapted to the delivery pipe 6 is provided on one side wall of the housing 4. The delivery pipe 6 is fixedly embedded in the mounting hole 16. One end of the delivery pipe 6 is fixedly connected to the top of one set of filter cartridges 7, and the other end of the delivery pipe 6 is fixedly connected to the gas generator body 2. By setting the mounting hole 16, the delivery pipe 6 is installed and positioned.

[0031] In addition, it also includes a delivery pump 17, which is fixedly installed on one side wall of the housing 4 and is electrically connected to the delivery pipe 6. The delivery pump 17 is electrically connected to a controller through a wire. The circuit connection is a mature existing technology. The specific connection method and working principle will not be elaborated here. By starting the delivery pump 17 through the controller, the gas generated by the gas generator body 2 can be pumped through the delivery pipe 6 to the inside of the filter cartridge 7 for filtration.
