Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a device for harmless treatment of chemical waste gas. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, odor purification, acid and alkali waste gas purification, and chemical waste gas purification. With social development, people are paying more and more attention to environmental protection, and a series of waste gases have an impact on the environment. Among these waste gases, the waste gases generated by chemical plants are the most serious pollutants. General chemical waste gases cannot be effectively treated during treatment, leading to their discharge and impacting the surrounding environment.

[0003] In the prior art, such as the announcement number CN213643674U, a highly efficient waste gas treatment device for chemical applications is proposed. This technical solution belongs to the field of waste gas treatment technology, and specifically to a highly efficient waste gas treatment device for chemical applications. It includes a housing with an air inlet on one side and an air outlet on the other side. A water filtration device is installed on the top of the housing. The interior of the housing contains a first treatment chamber, a second treatment chamber, a third treatment chamber, a fourth treatment chamber, and a fifth treatment chamber. A photocatalyst is coated on the surface of the placement columns, which, under the action of ultraviolet light, generates a strong catalytic degradation function. This effectively degrades toxic and harmful gases in the air, effectively kills various bacteria, and decomposes and neutralizes toxins released by bacteria or fungi. It also removes formaldehyde, deodorizes, resists stains, and purifies the air. The multiple placement columns are designed to increase the contact area between the waste gas and the photocatalyst, allowing for comprehensive purification and thus enhancing the purification effect.

[0004] However, when using the existing exhaust gas treatment device, if the staff needs to clean or replace the filter screen, they need to remove all the screws on the cover and then remove the cover before they can clean or replace the filter screen. This makes it inconvenient for the staff to clean or replace the filter screen.

[0005] To address the aforementioned issues, this application proposes a device for the harmless treatment of chemical waste gas. Utility Model Content

[0006] This utility model aims to provide a harmless treatment device for chemical waste gas, mainly to solve the problem that existing waste gas treatment devices require the removal of multiple screws on the cover before the cover can be removed to clean or replace the filter screen, which makes it inconvenient for workers to clean or replace the filter screen.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A chemical waste gas harmless treatment device includes a housing. A first frame, a second frame, and a third frame are inserted into the top of the housing. A dust filter is fixedly connected to the inner wall of the first frame, a particulate filter is fixedly connected to the inner wall of the second frame, and an activated carbon filter is fixedly connected to the inner wall of the third frame. A first pull block is fixedly connected to the top of each of the first, second, and third frames. Sliding plates are slidably connected to both ends of the first, second, and third frames at the top of the housing. T-shaped blocks are fixedly connected to both ends of the bottom of each sliding plate. A T-shaped groove matching the T-shaped blocks is provided on the top of the housing. A driving component for synchronous movement of the two sliding plates is provided on one side of the two sliding plates. A limiting component for fixing the sliding plate is provided on one of the sliding plates.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When this device is in use, (exhaust gas enters the first treatment chamber through the air inlet, and is then treated by the dust filter, particle filter, and activated carbon filter inside the first treatment chamber. The exhaust gas then enters the second treatment chamber through the first ventilation pipe, where the electrostatic precipitator operates to treat the exhaust gas again. Next, the exhaust gas enters the third treatment chamber for water filtration. Finally, it enters the fourth treatment chamber through the second connecting pipe, where the heating plate inside the fourth treatment chamber heats the exhaust gas, reducing its humidity). (The part in parentheses represents prior art, which is not elaborated upon in this application.) After releasing the limiting component, pull one of the sliding components. When one sliding plate moves, another sliding plate moves synchronously in the opposite direction under the action of the drive component. When the two sliding plates have moved to a certain extent, the first pull block on the first frame, second frame and third frame can be pulled out from the inside of the box, so that the staff can clean or replace the dust filter, particle filter and activated carbon filter. After cleaning, the first frame, second frame and third frame are inserted into the box. Then, sliding one of the sliding plates will make the two sliding plates move synchronously in the direction of approach. After the two sliding plates have moved to a certain extent, the sliding plates are fixed by the limiting component, so that the first frame, second frame and third frame are fixed inside the box and the device can be used normally.

[0011] 2. Beneficial Effects: When cleaning or replacing the dust filter, particle filter, and activated carbon filter during use, the two sliding plates can be slid to the sides of the top of the housing after releasing the limiting components. Then, the first pull blocks on the first, second, and third frames can be pulled out from inside the housing, making it convenient for workers to clean or replace the dust filter, particle filter, and activated carbon filter. After cleaning, the first, second, and third frames are inserted into the housing, and the two sliding plates are slid to the top of the first, second, and third frames, and then fixed by the limiting components. The advantage of this design is that it makes the disassembly and assembly of the first, second, and third frames more convenient, thus making it easier for workers to clean or replace the dust filter, particle filter, and activated carbon filter.

[0012] Preferably, the drive assembly includes two sliding plates fixedly connected to each other on opposite sides with racks symmetrically arranged at both ends of the sliding plates. Symmetrical gears are rotatably connected to the top of the housing, and the racks are meshed with the gears. After the limiting assembly is released, one of the sliding plates is pulled to move it. As the sliding plate moves, the gears can be rotated through the racks fixed to it. As the gears rotate, the other sliding plate can be moved through the racks, thereby realizing that the two sliding plates move synchronously in opposite directions.

[0013] Preferably, the limiting component includes a sliding rod extending through one of the sliding plates, with the sliding rods symmetrically arranged on the sliding plates. The sliding rods are slidably connected to the sliding plates, and an insert block is fixedly connected to the lower end of the sliding rod. The bottom of the sliding plate has a receiving groove that matches the insert block, and the top of the housing has a slot that matches the insert block. A connecting plate is fixedly connected to the upper end of the sliding rod, and a second pull block is fixedly connected to the top of the connecting plate. Pulling the second pull block upwards can move the insert block upwards via the sliding rod. When the insert block disengages from the slot, the sliding plate can be pulled to move it. After the sliding plate moves directly above the first frame, the second frame, and the third frame, pressing the second pull block can move the insert block downwards via the sliding rod. When the insert block is inserted into the slot, it can effectively fix the sliding plate, thereby ensuring high stability of the first frame, the second frame, and the third frame after installation.

[0014] Preferably, a magnet is fixedly connected to the lower end of the insert block, and an iron piece attracted to the magnet is fixedly connected to the bottom of the inner wall of the slot. After pressing the second pull block to insert the insert block into the slot, the magnet at the lower end of the insert block will attract the iron piece inside the slot, thereby fixing the insert block inside the slot. This can further improve the stability of the first frame, the second frame and the third frame after installation.

[0015] Preferably, the bottom of the T-shaped block is rotatably connected to multiple ball bearings, which are distributed in a linear array at equal intervals on the T-shaped block. When the sliding plate is pulled to move it, the T-shaped block will slide inside the T-groove. The multiple ball bearings at the bottom of the T-shaped block can effectively reduce the friction between the T-shaped block and the inner wall of the T-groove, making it easier and less strenuous for people to pull the sliding plate to move it.

[0016] Preferably, a symmetrical protective shell is fixedly connected to the top of the housing. The gear and a partial rack are located inside the protective shell. The rack is slidably connected to the inner wall of the protective shell, and the gear is rotatably connected to the inner wall of the protective shell. The protective shell set on the top of the housing can not only play a better role in limiting and guiding the rack, thus making the two sliding plates more stable when moving synchronously through the drive assembly, but also provide better protection for the gear and rack.

[0017] Preferably, the corners of the first and second pull blocks are rounded, and the outer walls of the first and second pull blocks are covered with anti-slip sleeves. By making the corners of the first and second pull blocks rounded, it is more comfortable for the operator's hands to pull the first and second pull blocks. The anti-slip sleeves on the outer walls of the first and second pull blocks increase the friction between the operator's hands and the first and second pull blocks, thereby effectively preventing people from slipping when pulling the first and second pull blocks.

[0026] 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.

[0027] Please see Figure 1-7A harmless treatment device for chemical waste gas includes a housing 1. A first frame 2, a second frame 3, and a third frame 4 are inserted into the top of the housing 1. A dust filter 5 is fixedly connected to the inner wall of the first frame 2 to filter dust from the waste gas. A particulate filter 6 is fixedly connected to the inner wall of the second frame 3 to filter particles from the waste gas. An activated carbon filter 7 is fixedly connected to the inner wall of the third frame 4 to adsorb foreign matter from the waste gas. The first frame 2, second frame 3, and third frame 4... Each of the top sections is fixedly connected to a first pull block 8. A sliding plate 9 is slidably connected to both ends of the first frame 2, second frame 3, and third frame 4 at the top of the housing 1. T-shaped blocks 10 are fixedly connected to both ends of the bottom of the sliding plate 9. A T-shaped groove 11 matching the T-shaped block 10 is provided on the top of the housing 1. The T-shaped blocks 10 at the bottom of the sliding plate 9 and the T-shaped groove 11 on the housing 1 enhance the stability of the sliding plate 9 during movement. Multiple ball bearings 22 are rotatably connected to the bottom of the T-shaped block 10, and the ball bearings 22 are linearly arrayed and equidistantly distributed on the T-shaped block 10, which effectively reduces [damage / loss]. The friction between the T-shaped block 10 and the inner wall of the T-shaped groove 11 makes it easier and less strenuous to pull the sliding plate 9. A drive assembly for synchronous movement of the two sliding plates 9 is provided on opposite sides of each other. One of the sliding plates 9 has a limiting assembly for fixing it. After releasing the limiting assembly, pulling one sliding plate 9 will cause the other sliding plate 9 to move synchronously in the opposite direction under the action of the drive assembly. When the two sliding plates 9 have moved to a certain extent, they will respectively pull the first frame 2, the second frame 3, and the third frame 4. The first pull block 8 can be pulled out from inside the housing 1, making it convenient for staff to clean or replace the dust filter 5, particle filter 6, and activated carbon filter 7. After cleaning, the first frame 2, the second frame 3, and the third frame 4 are inserted into the housing 1 respectively. Sliding one of the sliding plates 9 will cause the two sliding plates 9 to move synchronously towards each other. After the two sliding plates 9 have moved to a certain extent, the sliding plates 9 are fixed by the limiting component, thus fixing the first frame 2, the second frame 3, and the third frame 4 inside the housing 1. The device can then be used normally.

[0028] like Figure 3 and Figure 4As shown, the drive assembly includes two sliding plates 9 fixedly connected to opposite sides by racks 12, with the racks 12 symmetrically arranged at both ends of the sliding plates 9. The top of the housing 1 is rotatably connected to symmetrical gears 13, with the racks 12 meshing with the gears 13. The top of the housing 1 is fixedly connected to symmetrical protective shells 23, with the gears 13 and some racks 12 located inside the protective shells 23. The racks 12 are slidably connected to the inner wall of the protective shells 23, and the gears 13 are rotatably connected to the inner wall of the protective shells 23. After the limiting assembly is released, one of the sliding plates 9 is pulled to move it. As the sliding plate 9 moves, the gears 13 can rotate through the racks 12 fixed to it. As the gears 13 rotate, the other sliding plate 9 can be moved through the racks 12, thereby realizing that the two sliding plates 9 move synchronously in opposite directions.

[0029] like Figure 2 and Figure 7 As shown, the limiting assembly includes a sliding rod 14 passing through one of the sliding plates 9, and the sliding rods 14 are symmetrically arranged on the sliding plates 9. The sliding rods 14 are slidably connected to the sliding plates 9. The lower end of the sliding rod 14 is fixedly connected to an insert block 15. The bottom of the sliding plate 9 has a receiving groove 16 that matches the insert block 15. The top of the housing 1 has a slot 17 that matches the insert block 15. The lower end of the insert block 15 is fixedly connected to a magnet 20. The bottom of the inner wall of the slot 17 is fixedly connected to an iron piece 21 that attracts the magnet 20. The upper end of the sliding rod 14 is fixedly connected to a connecting plate 18. The top of the connecting plate 18 is fixedly connected to a second pull block 19. The corners of the first pull block 8 and the second pull block 19 are rounded. The outer wall of the second pull block 19 is covered with an anti-slip sleeve. Pulling the second pull block 19 upward will cause the insert block 15 to move upward via the slide rod 14. After the insert block 15 is disengaged from the slot 17, the sliding plate 9 can be pulled to move it. After the sliding plate 9 moves directly above the first frame 2, the second frame 3, and the third frame 4, pressing the second pull block 19 will cause the insert block 15 to move downward via the slide rod 14. When the insert block 15 is inserted into the slot 17, the magnet 20 at the lower end of the insert block 15 will attract the iron piece 21 inside the slot 17, thereby fixing the insert block 15 inside the slot 17. This will provide a good fixing effect for the sliding plate 9, thus making the first frame 2, the second frame 3, and the third frame 4 highly stable after installation.

[0030] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0031] In operation, the device works as follows: Exhaust gas enters the first treatment chamber through the inlet, where it is treated by dust filters, particulate filters, and activated carbon filters. The exhaust gas then flows through the first ventilation duct into the second treatment chamber, where an electrostatic precipitator further treats it. Next, the exhaust gas enters the third treatment chamber for water filtration. Finally, it flows through the second connecting pipe into the fourth treatment chamber, where a heating plate heats the exhaust gas. (Reducing humidity in exhaust gas), the part in parentheses refers to prior art, which is not described in detail in this application. Pulling the second pull block 19 upwards will cause the insert block 15 to move upwards via the slide rod 14. When the insert block 15 disengages from the slot 17, one of the sliding plates 9 can be pulled to move. As the sliding plate 9 moves, the gear 13 can be rotated via the rack 12 fixed to it. As the gear 13 rotates, the other sliding plate 9 can be moved via the rack 12, thus realizing that the two sliding plates 9 move synchronously in opposite directions. When the two sliding plates 9 have moved to a certain extent, the second pull block 19 is pulled upwards. The first pull block 8 on the first frame 2, the second frame 3, and the third frame 4 can be pulled out from inside the housing 1, making it convenient for staff to clean or replace the dust filter 5, the particle filter 6, and the activated carbon filter 7. After cleaning, the first frame 2, the second frame 3, and the third frame 4 are inserted into the housing 1 respectively. Sliding one of the sliding plates 9 will move both sliding plates 9 in a synchronized direction. After the two sliding plates 9 are moved directly above the first frame 2, the second frame 3, and the third frame 4, pressing the second pull block 19 will allow the slide bar 14 to slide out. The insertion block 15 moves downward. When the insertion block 15 is inserted into the slot 17, the magnet 20 at the lower end of the insertion block 15 will attract the iron piece 21 inside the slot 17, thereby fixing the insertion block 15 inside the slot 17. This can effectively fix the sliding plate 9, resulting in high stability of the first frame 2, the second frame 3, and the third frame 4 after installation. This makes it easier to disassemble and assemble the first frame 2, the second frame 3, and the third frame 4, making it easier for workers to clean or replace the dust filter 5, the particle filter 6, and the activated carbon filter 7.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
