Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a small-scale VOCs waste gas treatment and purification device. Background Technology

[0002] Small-scale VOCs exhaust gas treatment and purification devices are typically used to treat relatively low concentrations and small-scale VOCs emissions. They are widely used in small factories, laboratories, offices, and homes to reduce VOCs pollution of the air and environment. Activated carbon adsorption is one of the most common VOCs exhaust gas treatment methods, particularly suitable for treating low-concentration VOCs. It achieves purification by adsorbing harmful gases from the air through the porous structure of activated carbon.

[0003] During the adsorption process of waste gas through activated carbon, due to the airflow direction, the path through the waste gas inside the activated carbon is always the same as the airflow direction. As a result, the activated carbon used for waste gas treatment is mainly the activated carbon along the airflow path, while the utilization rate of activated carbon in other areas is much lower than that of activated carbon along the airflow path, thus increasing the frequency of activated carbon replacement and cleaning. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a small-scale VOCs waste gas treatment and purification device, which has the advantage of improving the utilization rate of activated carbon adsorption components.

[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] like Figures 1 to 6 As shown, this utility model provides a small-scale VOCs waste gas treatment and purification device, including a device housing 1, a filter assembly 2 installed on the left side of the device housing 1, a drive assembly 3 installed on the top of the device housing 1, a transmission assembly 4 installed on the left side of the front of the device housing 1, a fixing assembly 5 installed on the top of the filter assembly 2, an air guide assembly 6 installed on the left side of the inner side of the device housing 1, an air inlet pipe 103 fixedly connected to the left side of the filter assembly 2, self-locking casters 101 installed around the bottom of the device housing 1, and an exhaust pipe 102 fixedly connected to the right side of the device housing 1. An activated carbon adsorption assembly 104 is installed in the middle of the inner side of the device housing 1. The air guide assembly 6 includes a rotating rod 601 that is movably sleeved inside the device housing 1. A fixing plate 602 is fixedly sleeved on the outer side of the rotating rod 601. Mounting plates 603 are fixedly connected to the top and bottom of the fixing plate 602. An air guide plate 604 is fixedly connected to the inner side of the mounting plate 603. The drive assembly 3 includes a motor 301 fixedly connected to the top of the device housing 1. A swing plate 302 is fixedly connected to the output shaft of the motor 301. A cylindrical block 303 is fixedly connected to the front of the swing plate 302.

[0024] In this embodiment, the starting motor 301 drives the swing plate 302 to rotate, thereby causing the cylindrical block 303 to slide along the inner side of the sliding groove 307, and driving the long strip plate 306 and the lifting rod 305 to reciprocate up and down, which in turn drives the rack plate 403 to reciprocate up and down. Through the meshing action with the gear 401, the rotating rod 601 drives the mounting plate 603 and the air guide plate 604 to reciprocate at a certain angle, so that the exhaust gas can also enter the interior of the activated carbon adsorption component 104 through the top left side and the bottom left side of the activated carbon adsorption component 104, thereby improving the utilization rate of the activated carbon adsorption component 104 and reducing the frequency of replacement and cleaning of the activated carbon adsorption component 104.

[0025] The filter assembly 2 includes a frame 201 fixedly connected to the left side of the device housing 1, a filter screen 202 installed on the inner side of the frame 201, and a handle block 203 fixedly connected to the top of the filter screen 202.

[0026] The filter screen 202 can perform preliminary filtration of larger particles of waste carried in the exhaust gas. The filter screen 202 can be removed from the inside of the frame 201 by using the handle block 203.

[0027] The drive assembly 3 also includes a positioning block 304 fixedly connected to the front of the device housing 1. A lifting rod 305 is movably sleeved on the top of the positioning block 304. A long strip plate 306 is fixedly connected to the top of the lifting rod 305. A sliding groove 307 is provided on the front of the long strip plate 306.

[0028] The sliding groove 307 and the cylindrical block 303 are adapted to each other. During the process of the swing plate 302 driving the cylindrical block 303 to rotate to the highest position, the lifting rod 305 drives the rack plate 403 to move vertically upward. During the process of the swing plate 302 driving the cylindrical block 303 to rotate to the lowest position, the lifting rod 305 drives the rack plate 403 to move vertically downward.

[0029] The transmission component 4 includes a T-shaped positioning strip 402 fixedly connected to the front of the device housing 1, and a rack plate 403 is installed on the outer side of the T-shaped positioning strip 402.

[0030] The back of the rack plate 403 is provided with a T-shaped groove, which is adapted to the T-shaped positioning strip 402 to position the rack plate 403.

[0031] The transmission assembly 4 also includes a gear 401 fixedly sleeved on the front of the rotating rod 601, and the gear 401 meshes with the left side of the rack plate 403.

[0032] When the rack plate 403 moves upward, the gear 401 drives the rotating rod 601 to rotate counterclockwise by a certain angle. When the rack plate 403 moves downward, the gear 401 drives the rotating rod 601 to rotate clockwise by a certain angle.

[0033] The fixing component 5 includes a rotating column 501 movably connected to the top of the frame 201. A support block 502 is fixedly connected to the top of the rotating column 501. A plug rod 503 is movably sleeved on the top of the support block 502. A fixing ring 504 is fixedly connected to the top of the plug rod 503. A stop block 505 is fixedly sleeved on the bottom of the outer side of the plug rod 503. A spring 506 is provided on the outer side of the plug rod 503. The spring 506 is located between the support block 502 and the stop block 505. A fixing groove 204 is provided on the top of the handle block 203. The fixing groove 204 is adapted to the plug rod 503.

[0034] Spring 506 pushes the stop block 505 downward, thereby inserting the rod 503 into the inner side of the fixing groove 204, thereby exerting a downward pushing force on the handle block 203 and the filter screen 202, so that the filter screen 202 fits tightly against the inner wall of the frame 201.

[0035] Working principle and usage process of this utility model:

[0036] Exhaust gas enters the interior of filter assembly 2 through intake pipe 103. Filter screen 202 intercepts and filters solid waste in the exhaust gas. After preliminary filtration, the exhaust gas enters the inner side of device housing 1. Through the guiding effect of air guide plate 604, the exhaust gas can not only enter the interior of activated carbon adsorption assembly 104 through the middle of the left side, but also through the front and back sides of the left side. The starting motor 301 drives the swing plate 302 to rotate, thereby causing the cylindrical block 303 to move along the sliding groove 307. The inner side slides, and drives the long strip plate 306 and the lifting rod 305 to move back and forth, which in turn drives the rack plate 403 to move back and forth. Through the meshing action with the gear 401, the rotating rod 601 drives the mounting plate 603 and the air guide plate 604 to swing back and forth at a certain angle, so that the exhaust gas can also enter the interior of the activated carbon adsorption component 104 through the top and bottom left side of the activated carbon adsorption component 104, thereby improving the utilization rate of the activated carbon adsorption component 104 and reducing the frequency of replacement and cleaning of the activated carbon adsorption component 104.
