Description

Technical Field

[0001] This invention relates to the field of catalyst processing, and more specifically, to a bag filter dust collector for antimony-based catalysts. Background Technology

[0002] Antimony-based catalyst baghouse dust collectors are mainly used to collect and separate antimony-containing catalyst dust or dust particles from related production processes, ensuring gas purification and catalyst recovery.

[0003] Existing antimony-based catalyst baghouse dust collectors consist of a housing, a dust inlet, a clean air outlet, a pulse jet cleaning mechanism, filter bags, and a dust removal mechanism. The filter bags contain antimony-based catalysts, and the dust and gas are filtered through the antimony-based catalysts and filter bags. However, the existing filter bags are long (e.g., 4-6 meters). The airflow from the pulse jet cleaning mechanism will attenuate along the length of the long filter bag, and a cleaning blind zone is easily formed at the bottom, resulting in incomplete cleaning of the bottom of the filter bag, which in turn leads to a decrease in the effective filtration area utilization rate of the filter bag.

[0004] Therefore, we have made improvements to this and proposed a bag filter dust collector for antimony-based catalysts. Summary of the Invention

[0005] The purpose of this invention is to address the problem that the airflow emitted by the existing pulse jet cleaning mechanism attenuates along the length of the long filter bag, making it easy for a dust removal blind zone to form at the bottom of the long filter bag, thus reducing the effective filtration area utilization rate of the long filter bag.

[0006] To achieve the above-mentioned objectives, the present invention provides a bag filter dust collector for antimony-based catalysts to solve the aforementioned problems.

[0011] As a preferred technical solution of this application, two sets of telescopic hollow rod one and telescopic hollow rod two are provided, and the two sets of telescopic hollow rod one and telescopic hollow rod two are respectively arranged on the outside of the lead rod and the connecting column.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: 1. To address the problem in the prior art where the airflow from the pulse jet cleaning mechanism attenuates along the length of the long filter bag, making it easy for a cleaning blind zone to form at the bottom of the long filter bag and thus reducing the effective filtration area utilization rate of the long filter bag, this application introduces a synchronous adjustment mechanism. This mechanism compresses the first filter screen, causing the second filter screen at the bottom of the first filter screen to gradually approach the output end of the existing pulse jet cleaning mechanism. This prevents the first and second filter screens from becoming clogged and improves the utilization rate of the filtration area of ​​the first and second filter screens. 2. By using a synchronized adjustment mechanism, the dust accumulated at the connection between the filter screen and the tube sheet is cleaned by vibrating the tube sheet, thereby improving the exhaust efficiency of the purified air and solving the problem of reduced purified air emission efficiency caused by dust solidification at the connection between the filter bag and the tube sheet in the existing technology. 3. By using a synchronous adjustment mechanism, the filter screen is twisted and compressed. The dual action of twisting and compression allows the dust to quickly detach from the filter screen and fall into the dust discharge mechanism, preventing the dust from re-attaching to the filter screen and thus preventing the dust from flowing back. This solves the problem of low cleaning efficiency caused by secondary dust flow in the prior art. Attached Figure Description

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] As described in the background art, the airflow ejected by the pulse jet cleaning mechanism will attenuate along the length of the long filter bag, making it easy to form a dust removal blind zone at the bottom of the long filter bag, resulting in a decrease in the effective filtration area utilization rate of the long filter bag.

[0020] To address this technical problem, the present invention provides a bag filter dust collector for antimony-based catalysts, which is applied to catalyst processing.

[0021] For details, please refer to Figure 1 - Figure 6 As shown, the antimony-based catalyst bag filter dust collector specifically includes: a housing 1, a tube sheet 101 disposed inside the housing 1, an air outlet 102 disposed on the tube sheet 101, a guide column 103 disposed on the tube sheet 101, a dust inlet 104 disposed on the housing 1, a clean air inlet 105 disposed on the housing 1, and a dust discharge mechanism 106 disposed at the bottom of the housing 1, including a synchronous adjustment mechanism 2 disposed inside the housing 1. In the prior art, the air outlet 102 is connected to the existing pulse jet cleaning mechanism, and the existing pulse jet cleaning mechanism compresses the gas and sprays it into the filter screen 201. The guide column 103 is used to fix the filter screen 201 so that the filter screen 201 is cylindrical. The dust discharge mechanism 106 is used to seal and discharge the dust. The synchronous adjustment mechanism 2 includes a filter screen 201 mounted on the tube sheet 101, a lead screw 202 mounted on the tube sheet 101, a sliding seat 203 mounted in the housing 1, a through hole 204 mounted on the sliding seat 203, a second filter screen 205 mounted on the sliding seat 203, and a motor 206 mounted in the housing 1.

[0022] The antimony-based catalyst bag dust collector provided by this invention addresses the problem in the prior art where the airflow from the pulse jet cleaning mechanism attenuates along the length of the long filter bag, making it easy for a cleaning blind zone to form at the bottom of the long filter bag, resulting in a decrease in the effective filtration area utilization of the long filter bag. This application provides a synchronous adjustment mechanism 2, which compresses the filter screen 201, causing the filter screen 205 at the bottom of the filter screen 201 to gradually approach the output end of the existing pulse jet cleaning mechanism. This prevents the filter screen 201 and the filter screen 205 from becoming clogged, thereby improving the utilization rate of the filtration area of ​​the filter screen 201 and the filter screen 205. By using the synchronous adjustment mechanism 2, the dust accumulated at the connection between the filter screen 201 and the tube sheet 101 is cleaned by vibrating the tube sheet 101, thereby improving the exhaust efficiency of the purified air and solving the problem of reduced purified air emission efficiency caused by the solidification of dust at the connection between the filter bag and the tube sheet 101 in the prior art. By using the synchronous adjustment mechanism 2, the filter screen 201 is twisted and compressed. The dual action of twisting and compression allows the dust to quickly detach from the filter screen 201 and fall into the dust discharge mechanism 106, preventing the dust from re-attaching to the filter screen 201 and the filter screen 205, and thus preventing the dust from flowing back. This solves the problem of low cleaning efficiency caused by the secondary flow of dust in the prior art.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an antimony-based catalyst bag dust collector has a sliding seat 203 threadedly connected to a lead screw 202, the sliding seat 203 being slidably mounted on a guide post 103, and the lead screw 202 being mounted at the output end of a motor 206. In use, the space formed by filter screen 201, sliding seat 203, and filter screen 205 contains an antimony-based catalyst. The through hole 204 guides the dust gas, which is discharged into the housing 1 through the dust gas port 104. The dust gas is purified by filter screen 201, filter screen 205, and the antimony-based catalyst, allowing the purified gas to be discharged from the outlet 102 to the clean gas port 105, thus achieving the transfer of clean gas. Figure 2 As shown, when motor 206 is started, motor 206 drives lead screw 202 to rotate. Lead screw 202 rotates and drives sliding seat 203 to slide upward along housing 1 and guide column 103. At this time, filter screen 201 is compressed and stacked together, so that the cylindrical filter screen 201 gradually shortens. By compressing filter screen 201, filter screen 205 at the bottom of filter screen 201 gradually approaches the output end of the existing pulse jet mechanism, preventing the existing pulse jet mechanism from not being able to reach the bottom of filter screen 201 and the surrounding area of ​​filter screen 205, preventing the bottom of filter screen 201 and filter screen 205 from becoming blocked, thereby improving the utilization rate of the filtration area of ​​filter screen 201 and filter screen 205. Furthermore, telescopic hollow rod 1 207 is provided on the corresponding surfaces of the flower plate 101 and the sliding seat 203, and telescopic hollow rod 208 is provided on the corresponding surfaces of the sliding seat 203 and the box 1. The lead screw 202 is wrapped by telescopic hollow rod 207 and telescopic hollow rod 208 to prevent the threads of the lead screw 202 from coming into contact with particles in the dust and gas, thus preventing the device from jamming during use. Figure 2 As shown, when the sliding seat 203 moves upward, the first telescopic hollow rod 207 retracts and the second telescopic hollow rod 208 unfolds. Furthermore, a connecting post 209 is provided on the corresponding surface of the housing 1 and the flower plate 101, a sliding seat 203 is slidably disposed on the connecting post 209, a sliding groove 210 is provided on the sliding seat 203, a pushing post 211 is slidably disposed on the sliding groove 210, a spring 212 is provided on the corresponding surface of the pushing post 211 and the sliding groove 210, and a groove 213 is provided on the connecting post 209, the groove 213 and the pushing post 211 are adapted to each other; The connecting post 209 is used to guide the sliding seat 203, such as Figure 2 As shown, when the sliding seat 203 slides upward, the actuating column 211 and the groove 213 on the sliding seat 203 are in a state of engagement and disengagement. Through the elasticity of the spring 212, the actuating column 211 impacts the groove 213, causing the connecting column 209 to vibrate. Through the connection between the connecting column 209 and the tube sheet 101, the tube sheet 101 vibrates. Since the connection between the filter screen 201 and the tube sheet 101 is the necessary passage for dust and gas purification, the area around this location is prone to local blockage due to the adhesion and accumulation of sticky dust and moist dust. By vibrating the tube sheet 101, the dust accumulated at the connection between the filter screen 201 and the tube sheet 101 is cleaned, thereby improving the exhaust efficiency of the purified air.

[0027] Furthermore, two sets of telescopic hollow rod 1 207 and telescopic hollow rod 208 are provided, and the two sets of telescopic hollow rod 1 207 and telescopic hollow rod 208 are respectively provided on the outside of the screw rod 202 and the connecting column 209; The connecting column 209 is wrapped by telescopic hollow rod 1 207 and telescopic hollow rod 208 to prevent the groove 213 from contacting particles in the dust and gas, and to prevent the device from jamming during use. By compressing the filter screen 201 through the synchronous adjustment mechanism 2, the filter screen 205 at the bottom of the filter screen 201 gradually approaches the output end of the existing pulse jet blowing mechanism, preventing the filter screen 201 and the filter screen 205 from becoming clogged, thereby improving the utilization rate of the filtration area of ​​the filter screen 201 and the filter screen 205. By vibrating the tube sheet 101, the dust accumulated at the connection between the filter screen 201 and the tube sheet 101 is cleaned, improving the exhaust efficiency of the purified air. Example 2 further optimizes the antimony-based catalyst bag filter dust collector provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a second motor 214 is provided on the sliding seat 203, and a worm gear 215 is provided at the output end of the second motor 214. The worm gear 215 is rotatably mounted on the sliding seat 203. A transmission cavity 216 is provided on the sliding seat 203, and a worm wheel 217 is rotatably mounted inside the transmission cavity 216. The worm gear 215 and the worm wheel 217 are compatible. A first filter screen 201 is mounted on the worm wheel 217 and is rotatably mounted on the transmission cavity 216. When motor 214 is started, its output drives worm 215 to rotate. Worm 215 rotates and drives worm wheel 217 to rotate. At this time, filter screen 201 on worm wheel 217 rotates synchronously along the transmission cavity. Then, motor 206 is started, which compresses filter screen 201. Filter screen 201 is in a state of compression and torsion. The torsion guides the dust to slide down the spiral channel of filter screen 201. The compression of filter screen 201 and the vibration of tube sheet 101 accelerate the dust to detach from filter screen 201. The dual action allows the dust to quickly detach from filter screen 201 and fall into ash discharge mechanism 106, preventing the dust from re-attaching to filter screen 201 and filter screen 205, and thus preventing the secondary backflow of flue gas. Furthermore, the worm gear 215 is provided in two sets, and each set of the worm gear 215 is provided with a transmission wheel 218, and the two sets of transmission wheels 218 are provided with a conveyor belt 219. When motor 214 drives worm 215 to rotate, worm 215 rotates and drives transmission wheel 218 to rotate synchronously. Through the transmission of conveyor belt 219, the two sets of worms 215 rotate synchronously. Furthermore, a U-shaped cavity 220 is provided on the sliding seat 203, and the second motor 214 is provided on the U-shaped cavity 220; By cooperating with the housing 1, the U-shaped cavity 220 is isolated from the dust and gas, thereby preventing the dust and gas from coming into contact with the components inside the U-shaped cavity 220 and reducing the possibility of the device malfunctioning. The synchronous adjustment mechanism 2 drives the filter screen 201 to twist and compress. Through the dual action of twisting and compression, the dust is quickly removed from the filter screen 201 and falls into the dust discharge mechanism 106, preventing the dust from re-attaching to the filter screen 201 and the filter screen 205, and thus preventing the dust from flowing back.

[0028] The usage process of the antimony-based catalyst bag filter dust collector provided by this invention is as follows: During use, dusty gas is discharged into the housing 1 through the dust inlet 104. The dusty gas is purified by filter screen 201, filter screen 205, and antimony-based catalyst. The purified gas is then discharged from the outlet 102 into the clean gas inlet 105, achieving the transfer of clean gas. The motor 206 is started, which drives the lead screw 202 to rotate. The rotation of the lead screw 202 drives the sliding seat 203 to slide upward along the housing 1 and the guide column 103. At this time, the filter screen 201 is compressed and stacked together, forming a cylindrical filter. As the filter screen 201 gradually shortens, the filter screen 205 at the bottom of the filter screen 201 gradually approaches the output end of the existing pulse jet mechanism. This prevents the existing pulse jet mechanism from failing to reach the bottom of the filter screen 201 and the surrounding area of ​​the filter screen 205, and prevents clogging of the filter screens 201 and 205. When the sliding seat 203 slides upward, the push post 211 and the groove 213 on the sliding seat 203 are in a state of engagement and disengagement, which is achieved by the spring 212. The elasticity of the material causes the jacking column 211 to impact the groove 213, resulting in vibration of the connecting column 209. This vibration, caused by the connection between the connecting column 209 and the tube sheet 101, cleans the dust accumulated at the connection between the filter screen 201 and the tube sheet 101. At this point, the second motor 214 is activated, driving the worm gear 215 to rotate. The rotation of the worm gear 215 then drives the transmission wheel 218 to rotate synchronously. Through the transmission of the conveyor belt 219, the two sets of... The worm gear 215 rotates synchronously, driving the worm wheel 217 to rotate. At this time, the filter screen 201 on the worm wheel 217 rotates synchronously along the transmission cavity. The filter screen 201 is in a state of compression and torsion. The torsion guides the dust to slide down the spiral channel of the filter screen 201 in a directional manner. The compression of the filter screen 201 and the vibration of the tube sheet 101 accelerate the dust to detach from the filter screen 201. The dual action allows the dust to quickly detach from the filter screen 201 and fall into the dust discharge mechanism 106, preventing the dust from flowing back.
