[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this invention, chemical gases enter the device and filter cartridge through the inlet. First, they pass through a coarse filter to remove large particulate impurities and suspended solids. The coarsely filtered gas then passes through a fine filter to further remove smaller particles and impurities. The gas then passes through an activated carbon filter layer, where the activated carbon adsorbs harmful chemicals, odors, and some organic pollutants. Finally, the gas passes through a HEPA filter to remove extremely fine particles, ensuring high cleanliness. The clean gas, after multi-stage filtration, accumulates inside the chamber and is then discharged from the device through the exhaust port. This design ensures highly efficient purification of chemical gases during collection and treatment.
[0013] 2. This utility model allows for the installation and fixing of the mounting bracket by pressing a knob, which compresses the sleeve, thereby compressing the spring. Simultaneously, the knob moves the sliding rod and two sets of contact rods to one side. The two sets of contact rods move along the two sets of through grooves to the inside of the insertion groove. Rotating the knob causes the sliding rod and the two sets of contact rods to rotate. When the two sets of contact rods align with the two sets of contact grooves, releasing the knob causes the sleeve to move in the opposite direction due to the spring's reaction force. The sleeve then moves the knob in the opposite direction, and the knob moves the sliding rod and the two sets of contact rods in the opposite direction to engage with the two sets of contact grooves, thus completing the installation and fixing of the mounting bracket. Reversing the operation allows for the disassembly of the mounting bracket. This design facilitates the assembly and disassembly of multi-stage filtration mechanisms, simplifying equipment maintenance. Attached Figure Description

Detailed Implementation
[0023] 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.
[0024] Example 1
[0025] Please refer to Figure 1-8 As shown, this utility model provides a chemical gas collection and treatment device for chemical product production, including a base 1, a box 2 on the top of the base 1, a box cover 3 installed on the top of the box 2, a lifting mechanism for easy opening and closing of the box cover 3 on one side of the top of the base 1 located on the box 2, an air inlet 4 on the top of the box cover 3, an exhaust port 5 on one side of the box 2 near the bottom, a filter cylinder 13 at the bottom of the box cover 3, a multi-stage filtration mechanism on the inner side of the filter cylinder 13, and a snap-fit mechanism for easy disassembly and assembly connected to the filter cylinder 13.
[0026] Specifically, the chemical gas enters the device through the inlet 4 and is purified by the multi-stage filtration mechanism inside the filter cartridge 13, ensuring the purification effect of the chemical gas. The purified gas is collected in the housing 2 and discharged through the exhaust port 5. When maintenance or replacement of the multi-stage filtration mechanism is required, the housing cover 3 and the filter cartridge 13 can be easily raised through the lifting mechanism. The multi-stage filtration mechanism can be easily disassembled and assembled through the set snap-fit mechanism. Thus, through the above structure, efficient purification and convenient maintenance of chemical gas are ensured during the collection and treatment process.
[0027] The multi-stage filtration mechanism includes a coarse filter 18, a fine filter 19, an activated carbon filter layer 20, and a HEPA filter 21. Four sets of slots 14 are sequentially formed on the inner side of the filter cartridge 13 from top to bottom. Four sets of grooves 15 are formed on one side of the filter cartridge 13, each communicating with one of the four sets of slots 14. Mounting brackets 16 are inserted into the inner sides of each of the four sets of slots 14. The coarse filter 18, fine filter 19, activated carbon filter layer 20, and HEPA filter 21 are respectively installed on the inner sides of the four sets of mounting brackets 16. After the chemical gas enters the device and filter cartridge 13 through the inlet 4, it first passes through the coarse filter 18. Large particulate impurities and suspended solids in the gas can be removed. After coarse filtration, the gas continues to pass through fine filter 19, which can further remove smaller particles and impurities. The gas passes through activated carbon filter layer 20, where activated carbon adsorbs harmful chemicals, odors, and some organic pollutants in the gas. Finally, the gas passes through HEPA filter 21, which can remove extremely fine particulate matter, ensuring that the gas reaches a high level of cleanliness. The clean gas after multi-stage filtration is collected in the housing 2 and then discharged from the device through exhaust port 5. Thus, through the design, efficient purification of chemical gases is ensured during the collection and treatment process.
[0028] The locking mechanism includes a contact rod 27. A handle 17 is provided on one side of the mounting bracket 16. Movable grooves 22 are provided on both sides of the handle 17 on the mounting bracket 16. A sleeve 23 is slidably connected to the inner side of the movable groove 22 and connected to the movable groove 22 via a spring 24. A sliding rod 25 is slidably connected to the inner side of the sleeve 23. A knob 26 is connected to one end of the sliding rod 25. Two sets of contact rods 27 are symmetrically installed on the outer ring of the other end of the sliding rod 25. Insertion grooves 28 are provided near both ends of the groove 15. Two sets of through grooves 29, adapted to the contact rods 27, are symmetrically provided at the opening of the insertion grooves 28. Two sets of contact grooves 30, adapted to the contact rods 27, are symmetrically provided on the inner wall of one side of the insertion grooves 28. By pressing the knob 26, the knob 26 can compress the sleeve 23, which in turn compresses the spring 24. When the knob 26 is turned, it can drive the slide rod 25 and the two sets of abutment rods 27 to move to one side. The two sets of abutment rods 27 can move along the two sets of through grooves 29 to the inside of the insertion groove 28. Then, by turning the knob 26, the knob 26 can drive the slide rod 25 and the two sets of abutment rods 27 to rotate. When the two sets of abutment rods 27 rotate to align with the two sets of abutment grooves 30, by releasing the knob 26, under the action of the reaction force of the spring 24, the sleeve 23 can be driven to move in the opposite direction. The sleeve 23 can drive the knob 26 to move in the opposite direction. The knob 26 can drive the slide rod 25 and the two sets of abutment rods 27 to move in the opposite direction and engage with the two sets of abutment grooves 30, thereby completing the installation and fixing of the mounting bracket 16. The mounting bracket 16 can be disassembled by reversing the operation. In this way, the multi-stage filtration mechanism can be easily disassembled and assembled, which is convenient for equipment maintenance.
[0029] The lifting mechanism includes a drive motor 10, a support frame 6 on the top of the base 1, a mounting groove 7 on one side of the base 1, and a cover plate 8 on one side of the mounting groove 7. A screw 9 is rotatably connected to the inner side of the support frame 6, and one end of the screw 9 is connected to the output end of the drive motor 10 installed inside the mounting groove 7. A lifting plate 11, threadedly connected to the screw 9, is slidably connected to the inner side of the support frame 6. A connecting plate 12 is connected to one end of the lifting plate 11, and one end of the connecting plate 12 is connected to one side of the box cover 3. Both the support frame 6 and the lifting plate 11 are rectangular. When the box cover 3 needs to be opened, the drive motor 10 is started, which drives the screw 9 to rotate. The screw 9 is threadedly connected to the lifting plate 11, and the rotation of the screw 9 causes the lifting plate 11 to move along the support frame 6. The inner side of the frame 6 moves up and down. When the lifting plate 11 moves upward, it drives the cover 3 to rise together through the connecting plate 12, thus opening the cover 3. When the lifting plate 11 moves downward, it drives the cover 3 to fall through the connecting plate 12, thus closing the cover 3. When the cover 3 rises to a certain height, the operator can maintain or replace the filter mechanism inside the box 2. After maintenance, the drive motor 10 reverses, causing the cover 3 to fall and close the box 2. The frame 6 and the lifting plate 11 are both rectangular, which can ensure stability and balance during the lifting process. The cover plate 8 covers the mounting groove 7, which can protect the drive motor 10 and its transmission components. Thus, through this design, the cover 3 can be opened and closed smoothly, making it convenient for the operator to maintain and operate the inside of the device.
[0030] The base 1 has four sets of universal casters 31 with brakes installed at its bottom, and the upright frame 6 has handles 32 installed on both sides. The universal casters 31 with brakes and the handles 32 make it easy to move the device.
[0031] Working principle: First, large particulate impurities and suspended matter in the gas can be removed by the coarse filter 18. After coarse filtration, the gas continues to pass through the fine filter 19, which can further remove smaller particles and impurities. The gas passes through the activated carbon filter layer 20, where the activated carbon adsorbs harmful chemicals, odors and some organic pollutants in the gas. Finally, the gas passes through the HEPA filter 21, which can remove extremely fine particulate matter, ensuring that the gas reaches a high level of cleanliness.
[0032] When the mounting bracket 16 and the multi-stage filtration mechanism need to be disassembled and maintained, the drive motor 10 is started, which drives the screw 9 to rotate. The rotation of the screw 9 causes the lifting plate 11 to move upward along the inner side of the upright 6. When the lifting plate 11 moves upward, it drives the box cover 3 to rise together through the connecting plate 12, thus opening the box cover 3. Then, by pressing the knob 26, the knob 26 can compress the sleeve 23 and the spring 24. At the same time, the knob 26 can drive the slide rod 25 and the two sets of abutment rods 27 to move to one side. The two sets of abutment rods 27 can move along the two sets of through grooves 29 to the insertion groove 2. Inside 8, by rotating knob 26, the slide rod 25 and the two sets of abutment rods 27 can be rotated. When the two sets of abutment rods 27 are aligned with the two sets of abutment grooves 30, by releasing knob 26, under the action of the reaction force of spring 24, the sleeve 23 and knob 26 can be moved in the opposite direction. Knob 26 can move slide rod 25 and the two sets of abutment rods 27 in the opposite direction and engage with the two sets of abutment grooves 30, thereby completing the installation and fixing of mounting bracket 16. The mounting bracket 16 can be disassembled by reversing the operation to facilitate the maintenance of the multi-stage filtration mechanism, thus completing the entire operation process.
