Description

Technical Field

[0001] The invention relates to the field of purification, in particular to a smoke circulation purifier. Background Art

[0002] In the prior art, the self-cleaning device inside the smoke circulation purifier is lacking or the cleaning effect of the self-cleaning device is poor, and smoke particles will continue to accumulate on the surface of the filter material. As time goes by, the pores of the filter material will be blocked, resulting in an increase in the resistance of the gas passing through the filter material. Therefore, the filter material is subjected to excessive smoke load for a long time, and its filtering performance will be affected, thereby greatly shortening the service life of the filter material. At the same time, many smoke circulation purifiers on the market have poor sealing effects, which will cause airflow short circuit or vortex formation. Some smoke may not reach the filtration area and directly flow out of the equipment, resulting in insufficient purification, and even a serious threat to the health and safety of the staff. Summary of the invention

[0003] Based on this, it is necessary to provide a fume circulation purifier to address the self-cleaning and sealing issues within the fume circulation purifier.

[0004] A smoke circulation purifier, the smoke circulation purifier comprises: a bracket assembly, the bracket assembly is provided with an exhaust chamber and an air outlet; a filter assembly, the filter assembly is arranged on the bracket assembly, the filter assembly is provided with a first air inlet and a second filter chamber, the first air inlet, the second filter chamber, the exhaust chamber and the air outlet are connected in sequence; a back-blowing assembly, the back-blowing assembly is arranged on the filter assembly, a part of the back-blowing assembly is located in the second filter chamber, the back-blowing assembly is provided with a back-blowing air inlet and a back-blowing hole, the back-blowing air inlet is connected to the back-blowing hole, and the back-blowing hole is arranged opposite to a part of the filter assembly; a cleaning assembly, the cleaning A cleaning component is arranged on the filter component and is located in the second filter cavity, the cleaning component is provided with a cleaning air inlet hole and a cleaning blowing hole, the back-blowing air inlet, the cleaning air inlet hole and the cleaning blowing hole are connected in sequence, and the cleaning blowing hole is arranged opposite to a part of the filter component; a collecting component, the collecting component is arranged on the filter component, and the collecting component is used to collect the filtered material of the filter component; a control component, the control component is arranged on the bracket component, and the control component is electrically connected to the filter component, the back-blowing component and the cleaning component; a fan component, the fan component is arranged on the bracket assembly and is located in the exhaust cavity.

[0005] The above discloses a smoke circulation purifier. First of all, its unique structural design makes the purification process efficient and stable. Through the coordinated operation of the support assembly, the filter assembly, the backflush assembly, the cleaning assembly, etc., the smoke can be effectively filtered. Before operation, a large amount of nitrogen needs to be flushed into the smoke circulation filter to ensure that the air inside the filter is completely emptied to prevent the particulate dust in the sucked-in gas from reacting with the air and causing serious impact. The fan assembly located in the exhaust chamber generates a strong suction force, so that the first air inlet of the filter assembly can efficiently introduce the dust-laden airflow and allow it to enter the second filter chamber. In the second filter chamber, the smoke is intercepted and separated to the greatest extent by the internal sintered plate filter, and the smoke particles are effectively removed, which greatly reduces the pollutant content in the exhaust gas, thereby improving the air quality and protecting the surrounding environment and personnel health. During the long-term filtering process, the filtering effect of the filter component will gradually deteriorate. At this time, the control component will detect that the blockage degree of the filter component is gradually increasing, and will control the backflush component and the cleaning component to clean the sintered plate filter of the filter component. A large amount of nitrogen is introduced into the backflush air inlet and sprayed out through the backflush hole. The backflush hole is precisely facing the backflush channel of the filter component, and the filter component is backflushed and cleaned periodically to blow off the smoke and dust of the sintered plate filter. This process can effectively remove the smoke and dust attached to the surface of the filter component, prevent its excessive accumulation from increasing the filtering resistance and reducing the filtering efficiency, effectively ensure the long-term stable operation of the filter component, extend its service life, and reduce the cost and manpower investment of frequent replacement of filter media. At the same time, combined with the coordinated work of the cleaning components, after the cleaning air inlet is connected to the gas source from the back-blowing air inlet, the gas is blown out through the cleaning air hole, and the cleaning air hole is aligned with the gap formed between multiple sintering plate filters. On the basis of back-blowing, further deep cleaning is performed to completely remove some stubborn fine smoke and dust particles, so that the filter component always maintains good filtering performance and ensures that the purification effect is always at a high level. The combination of the two greatly enhances the cleaning effect of the sintering plate, reduces the number of frequent replacements of the sintering plate, ensures production efficiency, and extends printing time. The collection component conveniently collects the filtered materials intercepted by the filter component to prevent them from scattering and causing secondary pollution. At the same time, it is also convenient for these materials to be centrally processed, recycled or safely disposed of, improving environmental protection benefits and resource utilization. The cleaned gas is recycled by the printer, further improving resource utilization.

[0006] In one embodiment, the filter assembly includes a first filter unit, a second filter unit and a third filter unit, the second filter unit is arranged on the support assembly, the first filter unit is arranged on the second filter unit, the third filter unit is arranged on the second filter unit and / or the support assembly, the first filter unit is provided with the first air inlet, the first filter cavity and the first air outlet, the second filter unit is provided with the second air inlet, the second filter cavity and the second air outlet, the third filter unit is provided with the third air inlet, the third filter cavity and the third air outlet, the first air inlet, the first filter cavity, the first air outlet, the second air inlet, the second filter cavity, the second air outlet, the third air inlet, the third filter cavity, the third air outlet, the exhaust cavity and the air outlet are connected in sequence. By connecting the first air inlet, the first filter cavity, the first air outlet, the second air inlet, the second filter cavity, the second air outlet, the third air inlet, the third filter cavity, the third air outlet, the exhaust cavity and the air outlet in sequence, a multi-stage filtering system is formed, which can gradually and finely process the smoke. The first air inlet of the first filter unit can efficiently absorb smoke and dust, preliminarily separate larger particles in the first filter chamber, and reduce the subsequent filtration pressure. The second filter unit further intercepts medium-sized pollutants in the second filter chamber, and effectively improves the overall filtration accuracy through a progressive filtration method. The third filter unit deeply purifies tiny particles and harmful gases in the third filter chamber to ensure that the exhaust gas meets higher environmental protection standards. This multi-stage filtration setting greatly enhances the adaptability of the filter component to different particle sizes and types of smoke, allowing the smoke circulation purifier to handle smoke exhaust gas with complex components. At the same time, each filter unit is relatively independent and works in coordination, which is convenient for separate maintenance or replacement of one of the units, reducing maintenance costs and difficulties, and ensuring the long-term stable and efficient operation of the smoke circulation purifier, playing an extremely important role in the field of industrial environmental protection.

[0007] In one embodiment, the first filter unit is a cyclone separation filter. By setting the first filter unit as a cyclone separation filter, when the dust-laden gas enters the first filter chamber through the tangential direction of the first air inlet, the gas rotates at a high speed in the chamber. During the rotation process, the centrifugal force is used to throw the smoke and dust particles with larger mass toward the wall of the device, and then slides along the wall to the collection assembly at the bottom for collection. This process can effectively separate a large number of smoke and dust particles with larger particle sizes from the airflow.

[0008] In one embodiment, the second filter unit is a sintered plate filter. By setting the second filter unit as a sintered plate filter, its unique sintered structure forms many tiny and uniform pores, which can effectively intercept the fine smoke particles remaining after passing through the cyclone separation filter, including some tiny dust that is difficult to capture by conventional filters, greatly improving the ability of the entire filtration system to remove solid particles in the smoke, and further purifying the gas. At the same time, it has good stability and durability. The sintered plate material is strong and can withstand certain pressure and temperature changes. It is not easy to deform or damage during long-term operation, ensuring the stability and continuity of the filtration process. Compared with some more fragile filter media, the sintered plate filter can work stably under relatively harsh working conditions, improving the overall reliability of the equipment. Furthermore, the self-cleaning performance of the sintered plate filter is relatively good, and its surface characteristics make it easier for some attached smoke to fall off under the action of the backflush component and the cleaning component, which can maintain its own filtration efficiency to a certain extent and reduce the need for frequent replacement or deep cleaning. This not only reduces the maintenance cost of the equipment, but also enables the equipment to always maintain a relatively efficient filtration state during operation, ensuring the long-term stable operation and good purification effect of the smoke circulation purifier.

[0009] In one embodiment, the third filter unit is a HEPA high efficiency filter. By setting the third filter unit as a HEPA high efficiency filter, after being processed by the previous cyclone separation filter and the sintered plate filter, the remaining harmful particles such as tiny dust and bacteria in the gas can be effectively intercepted by the HEPA high efficiency filter, and its filtration efficiency can reach a very high precision, greatly improving the ability of the entire purifier to remove fine pollutants, ensuring that the discharged gas contains almost no tiny harmful solid particles.

[0010] In one embodiment, the second filter unit includes a filter box, a sintered plate, a support, a fixed plate and a collection box, the filter box is arranged on the support assembly, the collection box is arranged on the filter box and encloses to form the second filter cavity, the support is arranged on the filter box, the number of the sintered plates is multiple, the multiple sintered plates are arranged at intervals along the length direction of the support and are located in the second filter cavity, the fixed plate is arranged on the multiple sintered plates, and the sintered plates are provided with multiple backflush channels. By arranging the filter box on the support assembly, a stable shell structure is provided for the entire unit to ensure that the internal filtering process is not disturbed by the outside world. Multiple sintered plates are arranged at intervals along the support, which greatly increases the filtering area, improves the interception efficiency of smoke and dust, can effectively capture fine particles, and improve the overall filtering effect. The collection box cooperates with the filter box to form the second filter cavity, which not only provides a specific space for smoke and dust filtering, but also facilitates the collection of dust falling during the filtering process to prevent secondary dust pollution. The fixed plate ensures the stability of the sintered plate, so that it can still maintain a good filtering form under the conditions of airflow impact and equipment operation vibration. The backflush channel on the sintering plate can make the backflush airflow act evenly on the surface of the sintering plate when the backflush assembly is working, effectively remove the attached smoke and dust, prevent blockage, extend the service life of the sintering plate, and ensure the continuous and stable operation of the second filter unit, thus laying a solid foundation for the efficient purification work of the entire smoke circulation purifier.

[0011] In one embodiment, the filter box includes a box body, an inspection door plate, a sealing door plate and a spoiler, the box body is arranged on the support assembly, the inspection door plate and the sealing door plate are arranged on two opposite sides of the box body, the spoiler is arranged on the box body and is located in the second filter cavity, the cleaning assembly is arranged on the inspection door plate and penetrates the multiple intervals formed between the multiple sintering plates, the backflush assembly is arranged on the fixed plate and the multiple backflush holes are arranged one by one with the multiple backflush channels. By arranging the box body on the support assembly, a solid shell foundation is provided for the entire filter unit, ensuring the stability and sealing of the internal filtering environment. The inspection door plate facilitates the daily inspection, maintenance and troubleshooting of the various components inside the filter box (for example, when the sintering plate needs to be cleaned or replaced), greatly reducing the difficulty and time cost of equipment maintenance, and ensuring the continuous operation of the equipment. The sealing door plate further strengthens the sealing of the box, effectively prevents smoke and dust leakage, and ensures the purification effect. The setting of the spoiler can change the flow state of the airflow in the box, making the dust-laden airflow more evenly distributed in the second filter chamber, increasing the contact opportunity between the sintered plate and the smoke, thereby improving the filtration efficiency. The cleaning component can comprehensively and effectively clean the sintered plate by rationally arranging and running through the intervals between the sintered plates. The backflush component corresponds precisely to the backflush channel and can accurately backflush and clean the sintered plate. The synergistic effect of the two effectively prevents the sintered plate from being blocked, prolongs its service life, and maintains the efficient and stable operation of the filter component.

[0012] In one embodiment, the cleaning component includes a driving component, a mounting component and a cleaning member, wherein the driving component is arranged on the inner side wall of the filter component, the mounting component is arranged on the driving component, the cleaning member is arranged on the mounting component and is against the sintered plate of the filter component, the mounting component is provided with the cleaning air inlet hole, and the cleaning member is provided with a plurality of the cleaning air blowing holes. By arranging the driving component on the inner side wall of the filter component, a foundation for installation is provided for the mounting component and the cleaning member, ensuring that the driving component, the mounting component and the cleaning member can work stably and efficiently. The cleaning member directly against the sintered plate, introduces gas through the cleaning air inlet hole and blows it out through a plurality of cleaning air blowing holes, and can accurately and powerfully clean the sintered plate, a key filtering part, so that each dust-prone area of ​​the sintered plate can be properly cleaned, greatly improving the cleaning efficiency and effect, ensuring that the filter component always maintains good filtering performance, reducing the problem of reduced filtering efficiency due to incomplete cleaning, extending the overall service life of the filter component, ensuring the stable and efficient operation of the smoke circulation purifier, and reducing the equipment maintenance cost and frequency.

[0013] In one embodiment, the driving assembly includes a first motor, a first guide rail and a first slider, the number of the first guide rails is multiple, the multiple first guide rails are arranged on the filter assembly and extend along the length direction of the filter assembly, the first slider is arranged on the multiple first guide rails and extends along the setting direction of the sintering plate, the first motor is arranged on the filter assembly, the first slider is sleeved on the motor shaft of the first motor and the first slider is connected to the motor shaft of the first motor by transmission, and the mounting assembly is arranged on the first slider. By arranging multiple first guide rails on the filter assembly and extending along the length direction of the filter assembly, a stable and accurate guide path is provided for the first slider, so that the first slider can move smoothly on a predetermined track. The first slider extends along the setting direction of the sintering plate, which effectively increases the cleaning coverage and ensures that the filter assembly is cleaned in all directions. The first motor is arranged on the filter assembly and / or the first slider, which can provide a power source for the entire cleaning action, drive the first slider to move flexibly on the first guide rail, thereby driving the subsequent connected cleaning components to clean different positions of the filter assembly in an orderly manner. This structural design improves the degree of automation of the cleaning process, does not require a lot of manual intervention, and reduces labor costs and labor intensity. At the same time, the precise movement of the guide rail slider can effectively prevent the cleaning components from causing unnecessary collision or damage to the filter components, extend the service life of the equipment, ensure that the smoke circulation purifier always maintains good cleaning effect and stable filtering performance during long-term operation, and reduce the frequency of replacement of the sintered plate.

[0014] In one embodiment, the installation assembly includes a connector, a spring, a second guide rail, a second motor, a second slider and a vibrator, the number of the connectors is multiple, and the multiple connectors are movably arranged on the driving assembly, the second guide rail is arranged on the multiple connectors and extends along the setting direction of the sintering plate, the number of the springs is multiple, and the multiple springs are clamped one by one between the multiple connectors and the second guide rail, the second motor is arranged on the second guide rail, the second slider is slidably arranged on the second guide rail, the second slider is sleeved on the motor shaft of the second motor and the second slider is connected to the motor shaft of the second motor by transmission, the number of the vibrators is multiple, and the multiple vibrators are arranged on both sides of the second guide rail, the cleaning member is arranged on the second slider, and the second slider is provided with the cleaning air inlet. By closely connecting the multiple connectors with the driving assembly, the continuity and integrity of the cleaning action are ensured. The second guide rail extends along the direction of the sintering plate, providing a track for the second slider to move in a directional manner, making the cleaning operation more directional. The second motor set on the second guide rail drives the second slider, so that the second slider can move back and forth between the intervals of multiple sintering plates, so that the cleaning member set on the second slider can be in close contact with the sintering plate, achieving the effect of thoroughly cleaning the sintering plate. The vibrators distributed on both sides of the second guide rail, combined with the setting of the spring, can generate high-frequency back-and-forth vibrations, further causing the smoke and dust on the sintering plate to loosen and fall off, and cooperate with other components to greatly improve the cleaning effect, deeply remove the dirt that is difficult to remove in the sintering plate, ensure the efficient filtering performance of the sintering plate, and reduce the equipment operation resistance caused by dust accumulation, thereby improving the overall working efficiency and stability of the smoke and dust circulation purifier.

[0015] In one embodiment, the cleaning member includes a cleaning strip and a cleaning brush. The number of the cleaning strips is multiple, and the multiple cleaning strips are arranged along the length direction of the mounting assembly. The number of the cleaning brushes is multiple, and the multiple cleaning brushes are arranged circumferentially along the length direction of the cleaning strip. The multiple cleaning brushes are against the sintering plate. The cleaning strip is provided with multiple cleaning air blowing holes, and the multiple cleaning air blowing holes are connected to the cleaning air inlet holes, and the multiple cleaning air blowing holes are arranged relative to the sintering plate. By arranging multiple cleaning strips in an orderly manner along the second slider, the contact area with the sintering plate is greatly increased. Combined with the numerous cleaning brushes circumferentially arranged on the cleaning strips and the high-frequency vibration of the mounting assembly, the sintering plate can be deeply cleaned in all directions and at multiple angles. The cleaning air inlet is connected to the back-blowing air inlet of the back-blowing assembly, and the cleaning air inlet is connected to the cleaning air blowing hole on the cleaning strip. While the cleaning brush is physically cleaning, the gas of the back-blowing assembly can be introduced, and the cleaned smoke and dust can be further blown away from the sintering plate by blowing, effectively preventing it from attaching again, thereby improving the cleaning efficiency and quality. This combination of physical cleaning and airflow blowing can completely remove the stubborn smoke and dust on the sintering plate, so that the sintering plate always maintains good filtering performance, greatly reducing the risk of equipment operation failure caused by sintering plate blockage, ensuring the continuous and stable operation of the smoke circulation purifier, extending the service life of the filter assembly, reducing equipment maintenance and replacement costs, and providing a solid and powerful guarantee for efficient purification of smoke and dust, especially suitable for industrial smoke and dust treatment fields with high requirements for filtering accuracy and equipment stability.

[0016] In one embodiment, the back-blowing assembly includes an air storage part, a solenoid valve and a back-blowing bracket. The air storage part is arranged on the filter assembly. There are multiple solenoid valves, which are arranged along the length direction of the air storage part. There are multiple back-blowing brackets, which are arranged on the filter assembly and are connected to the multiple solenoid valves one by one. The solenoid valve is provided with the back-blowing air inlet, and the back-blowing bracket is provided with multiple back-blowing holes. By arranging the air storage part on the filter assembly, a stable and sufficient gas source is provided for the back-blowing operation, ensuring that gas can be supplied in time when back-blowing cleaning is required, and maintaining a stable back-blowing pressure. Multiple solenoid valves are arranged along the length direction of the air storage part. Solenoid valves at different positions can independently adjust the gas flow and on-off state according to actual needs, and accurately perform back-blowing operations on different areas of the filter assembly. Under different working conditions, the back-blowing parameters can be flexibly adjusted through the solenoid valve to adapt to the different cleaning requirements of the filter assembly, thereby improving the adaptability and intelligence of the equipment. Multiple back-blowing brackets are connected to the solenoid valves one by one, and are provided with multiple back-blowing holes, so that the back-blowing gas can act evenly and efficiently on various parts of the filter assembly, effectively removing the smoke and dust attached to the filter medium. This uniform back-blowing distribution avoids the problem of reduced filtering effect caused by uneven local back-blowing, effectively ensures that the filtering efficiency of the filter assembly is always at a high level, extends the service life of the filter assembly, reduces the cost and time consumption of frequent replacement or maintenance due to blockage of the filter assembly, thereby improving the operating stability and economy of the entire smoke and dust circulation purifier.

[0017] In one embodiment, the collecting assembly includes a first collecting member and a second collecting member, wherein the first collecting member is arranged on the first filter unit, and the second collecting member is arranged on the second filter unit. By arranging the first collecting member on the first filter unit, the large particles of smoke and dust separated by the cyclone separation filter during operation can be accurately collected. Since large particles of smoke and dust usually have a large mass and volume, the first collecting member can effectively prevent them from accumulating or scattering inside the filter, avoiding adverse effects on subsequent filtering links, and facilitating centralized processing and subsequent cleaning, thereby reducing maintenance costs. The second collecting member is located on the second filter unit and is specifically used to collect fine particles of smoke and dust intercepted by the sintered plate filter during the filtering process. It can ensure that these fine particles are properly collected to prevent air pollution caused by secondary dust or pollution of other components inside the equipment. The two collecting members each perform their duties and correspond to the collection requirements of different filter units, so that the smoke and dust waste generated during the entire filtering process can be collected and managed in an orderly manner, ensuring the cleanliness inside the smoke and dust circulation purifier and the stability of the overall operation, and improving the reliability and environmental protection performance of the equipment.

[0018] In one embodiment, the support assembly includes a support, a fan housing and a foot, the fan housing is arranged on the support, the number of the foot is multiple, and the multiple foots are arranged along the circumference of the support, the filter assembly and the control assembly are arranged on the support, and the fan assembly is arranged on the fan housing. By arranging the filter assembly and the control assembly on the support, it is ensured that each component remains stable during operation, the risk of failure caused by vibration or displacement is reduced, and the normal operation of the entire purifier is guaranteed. The fan housing is specifically used to place the fan assembly, providing a relatively independent and suitable operating space for the fan, which helps to optimize the working environment of the fan, reduce the interference of external factors on the performance of the fan, and facilitate the maintenance and overhaul of the fan. Multiple circumferentially arranged foots, on the one hand, can effectively buffer the vibration generated during the operation of the equipment, reduce noise, and improve the stability and comfort of the equipment operation; on the other hand, the foot can adjust the height of the equipment to adapt to different installation site ground conditions and ensure the levelness and stability of the equipment installation.

[0019] In one embodiment, the bracket assembly further includes a pulley, and the number of the pulleys is multiple, and the multiple pulleys are arranged along the bracket circumference of the bracket assembly. By distributing the multiple pulleys along the bracket circumference, the device has good mobility. When installing and adjusting the layout of the equipment, the operator only needs to adjust the height of the footrest, and can easily push the smoke circulation purifier to the designated position without the need for large-scale handling tools, which greatly saves manpower and time costs.

[0020] In one embodiment, a protection component is also included, and the protection component is connected to the filter component through a pipeline. By connecting the protection component and the filter component through a pipeline, inert particles can be flushed into them. During the filtering process, when active particles are filtered out, the inert particles can effectively prevent these active particles from contacting and reacting with each other. This measure greatly reduces the safety risks such as explosion and combustion that may be caused by the reaction of active particles, and ensures the safe and stable operation of the equipment. At the same time, since the new substances produced by the reaction of active particles are avoided from corroding, clogging or contaminating the filter component, the service life of the filter component is significantly extended, and the cost and maintenance workload of frequent replacement of the filter component are reduced. Moreover, a stable filtering environment helps to maintain the efficiency and sustainability of the entire purification process, ensure that the smoke circulation purifier can always purify the smoke with good performance, improve the reliability and adaptability of the equipment when processing smoke containing active particles, and provide a safer and more reliable smoke purification solution for related industrial production or special environment applications.

[0021] In one embodiment, the smoke circulation purifier is welded with stainless steel material. By using multiple stainless steel plates to weld the shell and other structures of the smoke circulation purifier, spot welding can accurately control the size and spacing of the welding points, effectively reduce the welding gap, and greatly reduce the possibility of gas leakage. This good sealing property allows the dust-containing gas to flow only along a predetermined path, avoiding gas escape and polluting the surrounding environment or affecting the filtering effect. Whether under high pressure or long-term operation, a stable sealing state can always be maintained, ensuring the stability of the working environment inside the sintered plate filter and improving the overall filtering performance and reliability.

[0022] In one embodiment, the smoke circulation purifier is made of stainless steel material connected by bolts. By fixing multiple stainless steel plates with bolts, precise tightening force adjustment can be achieved, so that the stainless steel plates fit tightly together, effectively filling small gaps, and greatly reducing gas leakage channels.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0047] The smoke circulation purifier according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0048] Example

[0049] like Figures 1 to 13 As shown, the present embodiment discloses a smoke circulation purifier, comprising: a support assembly 1, the support assembly 1 is provided with an exhaust chamber 101 and an air outlet 102; a filter assembly 2, the filter assembly 2 is arranged on the support assembly 1, the filter assembly 2 is provided with a first air inlet 201 and a second filter chamber 205, the first air inlet 201, the second filter chamber 205, the exhaust chamber 101 and the air outlet 102 are connected in sequence; a back-blowing assembly 3, the back-blowing assembly 3 is arranged on the filter assembly 2, a part of the back-blowing assembly 3 is located in the second filter chamber 205, the back-blowing assembly 3 is provided with a back-blowing air inlet 301 and a back-blowing hole 302, the back-blowing air inlet 301 is connected with the back-blowing hole 302, and the back-blowing hole 302 is arranged opposite to a part of the filter assembly 2 The cleaning component 4 is arranged on the filter component 2 and is located in the second filter cavity 205. The cleaning component 4 is provided with a cleaning air inlet hole 401 and a cleaning blowing hole 402. The back-blowing air inlet 301, the cleaning air inlet hole 401 and the cleaning blowing hole 402 are connected in sequence. The cleaning blowing hole 402 is arranged opposite to a part of the filter component 2; the collecting component 5 is arranged on the filter component 2, and the collecting component 5 is used to collect the filtered material of the filter component 2; the control component 6 is arranged on the bracket component 1, and the control component 6 is electrically connected to the filter component 2, the back-blowing component 3 and the cleaning component 4; the fan component 7 is arranged on the bracket component 1 and is located in the exhaust cavity 101.

[0050] The present application discloses a smoke circulation purifier. First, its unique structural design makes the purification process efficient and stable. Through the coordinated operation of the support assembly 1, the filter assembly 2, the backflush assembly 3, the cleaning assembly 4, etc., the smoke can be effectively filtered. Before operation, a large amount of nitrogen needs to be flushed into the smoke circulation filter to ensure that the air inside the filter is completely emptied to prevent the particulate dust in the sucked-in gas from reacting with the air and causing serious effects. The fan assembly 7 located in the exhaust chamber 101 generates a strong suction force, so that the first air inlet 201 of the filter assembly 2 can efficiently introduce the dust-containing airflow and allow it to enter the second filter chamber 205. In the second filter chamber 205, the smoke is intercepted and separated to the greatest extent by the internal sintered plate filter, and the smoke particles are effectively removed, which greatly reduces the pollutant content in the exhaust gas, thereby improving the air quality and protecting the surrounding environment and personnel health. During the long-term filtering process, the filtering effect of the filter component 2 will gradually deteriorate. At this time, the control component 6 will detect that the blockage degree of the filter component 2 is gradually increasing, and will control the backflush component 3 and the cleaning component 4 to clean the sintered plate filter of the filter component 2. The backflush air inlet 301 introduces a large amount of nitrogen gas and sprays it out through the backflush hole 302. The backflush hole 302 is precisely directed toward the backflush channel 206 of the filter component 2, and the filter component 2 is backflushed and cleaned periodically to blow off the smoke and dust of the sintered plate filter. This process can effectively remove the smoke and dust attached to the surface of the filter component, prevent its excessive accumulation from increasing the filtering resistance and reducing the filtering efficiency, effectively ensure the long-term stable operation of the filter component 2, extend its service life, and reduce the cost and manpower investment of frequent replacement of the filter medium. At the same time, combined with the coordinated work of the cleaning component 4, after the cleaning air inlet 401 is connected to the air source from the back-blowing air inlet 301, the gas is blown out through the cleaning blowing hole 402, and the cleaning blowing hole 402 is aligned with the gap formed between multiple sintered plate filters. On the basis of back-blowing, further deep cleaning is performed to completely remove some stubbornly attached fine smoke and dust particles, so that the filter component 2 always maintains good filtering performance and ensures that the purification effect is always at a high level. The combination of the two greatly enhances the cleaning effect of the sintered plate 222, reduces the number of frequent replacements of the sintered plate 222, ensures production efficiency, and extends printing time. The collection component 5 conveniently collects the filtered materials intercepted by the filter component 2 to prevent them from scattering and causing secondary pollution. At the same time, it is also convenient for these materials to be centrally processed, recycled or safely disposed of, thereby improving environmental protection benefits and resource utilization. The cleaned gas is recycled by the printer, further improving resource utilization.

[0051] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines that: the filter assembly 2 includes a first filter unit 21, a second filter unit 22 and a third filter unit 23, the second filter unit 22 is arranged on the bracket assembly 1, the first filter unit 21 is arranged on the second filter unit 22, the third filter unit 23 is arranged on the second filter unit 22 and / or the bracket assembly 1, the first filter unit 21 is provided with a first air inlet 201, a first filter cavity 202 and a first air outlet 203, the second filter unit 21 is provided with a first air inlet 201, a first filter cavity 202 and a first air outlet 203, The unit 22 is provided with a second air inlet 204, a second filter cavity 205 and a second air outlet 207, the third filter unit 23 is provided with a third air inlet 208, a third filter cavity 209 and a third air outlet 210, and the first air inlet 201, the first filter cavity 202, the first air outlet 203, the second air inlet 204, the second filter cavity 205, the second air outlet 207, the third air inlet 208, the third filter cavity 209, the third air outlet 210, the air extraction cavity 101 and the air outlet 102 are sequentially connected. By sequentially connecting the first air inlet 201, the first filter cavity 202, the first air outlet 203, the second air inlet 204, the second filter cavity 205, the second air outlet 207, the third air inlet 208, the third filter cavity 209, the third air outlet 210, the air extraction cavity 101 and the air outlet 102, a multi-stage filtering system is formed, which can gradually and finely process the smoke. The first air inlet 201 of the first filter unit 21 can efficiently absorb smoke and dust, preliminarily separate larger particles in the first filter chamber 202, and reduce the subsequent filtering pressure. The second filter unit 22 further intercepts pollutants of medium particle size in the second filter chamber 205, and effectively improves the overall filtering accuracy through a progressive filtering method. The third filter unit 23 deeply purifies tiny particles and harmful gases in the third filter chamber 209 to ensure that the exhaust gas meets higher environmental protection standards. This multi-stage filtration setting greatly enhances the adaptability of the filter component to smoke of different particle sizes and types, so that the smoke circulation purifier can handle smoke exhaust gas with complex components. At the same time, each filter unit is relatively independent and works in coordination, which is convenient for separate maintenance or replacement of one of the units, reducing the maintenance cost and difficulty, and ensuring the long-term stable and efficient operation of the smoke circulation purifier, playing an extremely important role in the field of industrial environmental protection.

[0052] like Figure 3 and Figure 5As shown, in addition to the features of the above embodiment, this embodiment further defines that: the first filter unit 21 is a cyclone separation filter. By setting the first filter unit 21 as a cyclone separation filter, when the dust-laden gas enters the first filter chamber through the tangential direction of the first air inlet, the gas rotates at a high speed in the chamber. During the rotation process, the centrifugal force is used to throw the smoke particles with larger mass toward the wall of the device and then slide along the wall to the collection assembly 5 at the bottom for collection. This process can effectively separate a large number of smoke particles with larger particle sizes from the airflow.

[0053] like Figure 3 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the second filter unit 22 is a sintered plate filter. By setting the second filter unit 22 as a sintered plate filter, its unique sintering structure forms many tiny and uniform pores, which can effectively intercept the fine smoke particles remaining after passing through the cyclone separation filter, including some tiny dust that is difficult to capture by conventional filters, greatly improving the ability of the entire filtration system to remove solid particles in the smoke, and further purifying the gas. At the same time, it has good stability and durability. The sintered plate material is strong and can withstand certain pressure and temperature changes. It is not easy to deform or damage during long-term operation, ensuring the stability and continuity of the filtration process. Compared with some relatively fragile filter media, the sintered plate filter can work stably under relatively harsh working conditions, improving the overall reliability of the equipment. Furthermore, the self-cleaning performance of the sintered plate filter is relatively good, and its surface characteristics make some attached smoke easier to fall off under the action of the backflush component 3 and the cleaning component 4, which can maintain its own filtration efficiency to a certain extent and reduce the need for frequent replacement or deep cleaning. This not only reduces the maintenance cost of the equipment, but also enables the equipment to always maintain a relatively efficient filtration state during operation, ensuring the long-term stable operation and good purification effect of the smoke circulation purifier.

[0054] like Figure 3 and Figure 6 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the third filter unit 23 is a HEPA high efficiency filter. By setting the third filter unit 23 as a HEPA high efficiency filter, after being processed by the previous cyclone separation filter and the sintered plate filter, the remaining harmful particles such as tiny dust and bacteria in the gas can be effectively intercepted by the HEPA high efficiency filter, and its filtering efficiency can reach a very high precision, greatly improving the ability of the entire purifier to remove fine pollutants, ensuring that the discharged gas contains almost no tiny harmful solid particles.

[0055] like Figure 4 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiment, this embodiment further defines that: the second filter unit 22 includes a filter box 221, a sintered plate 222, a support 223, a fixed plate 224 and a collection box 225, the filter box 221 is arranged on the support assembly 1, the collection box 225 is arranged on the filter box 221 and encloses to form a second filter cavity 205, the support 223 is arranged on the filter box 221, the number of sintered plates 222 is multiple, the multiple sintered plates 222 are arranged at intervals along the length direction of the support 223 and are located in the second filter cavity 205, the fixed plate 224 is arranged on the multiple sintered plates 222, and the sintered plates 222 are provided with multiple backflush channels 206. By arranging the filter box 221 on the support assembly 1, a stable shell structure is provided for the entire unit to ensure that the internal filtering process is not disturbed by the outside world. Multiple sintered plates 222 are arranged at intervals along the support 223, which greatly increases the filtering area, improves the interception efficiency of smoke and dust, can effectively capture fine particles, and improve the overall filtering effect. The collection box 225 cooperates with the filter box 221 to form the second filter chamber 205, which not only provides a specific space for smoke and dust filtering, but also facilitates the collection of dust that falls during the filtering process to prevent secondary dust pollution. The fixed plate 224 ensures the stability of the sintering plate 222, so that it can still maintain a good filtering state under the conditions of airflow impact and equipment operation vibration. When the backflush assembly 3 is working, the backflush channel 206 on the sintering plate 222 can make the backflush airflow act evenly on the surface of the sintering plate 222, effectively remove the attached smoke and dust, prevent blockage, extend the service life of the sintering plate 222, and ensure the continuous and stable operation of the second filter unit 22, thereby laying a solid foundation for the efficient purification work of the entire smoke circulation purifier.

[0056] like Figure 2 and Figure 5As shown, in addition to the features of the above embodiment, this embodiment further defines that: the filter box 221 includes a box body 2211, an inspection door plate 2212, a sealing door plate 2213 and a spoiler 2214, the box body 2211 is arranged on the bracket assembly 1, the inspection door plate 2212 and the sealing door plate 2213 are arranged on two opposite sides of the box body 2211, the spoiler 2214 is arranged on the box body 2211 and is located in the second filter cavity 205, the cleaning component 4 is arranged on the inspection door plate 2212 and penetrates a plurality of intervals formed between a plurality of sintering plates 222, the backflush component 3 is arranged on the fixing plate 224 and a plurality of backflush holes 302 are arranged one by one with a plurality of backflush channels 206. By arranging the box body 2211 on the bracket assembly 1, a solid shell foundation is provided for the entire filter unit, ensuring the stability and sealing of the internal filtering environment. The inspection door panel 2212 facilitates the daily inspection, maintenance and troubleshooting of the internal components of the filter box 221 (for example, when the sintering plate 222 needs to be cleaned or replaced), greatly reducing the difficulty and time cost of equipment maintenance and ensuring the continuous operation of the equipment. The sealing door panel 2213 further strengthens the sealing of the box, effectively prevents smoke and dust leakage, and ensures the purification effect. The setting of the spoiler 2214 can change the flow state of the airflow in the box, so that the dust-containing airflow is more evenly distributed in the second filter cavity 205, and increases the contact opportunity between the sintering plate 222 and the smoke, thereby improving the filtration efficiency. The cleaning component 4 can comprehensively and effectively clean the sintering plate 222 by reasonably arranging and running through the intervals between the sintering plates 222. The backflush component 3 corresponds precisely to the backflush channel 206, and can accurately backflush and clean the sintering plate 222. The two work together to effectively prevent the sintering plate 222 from being blocked, extend its service life, and maintain the efficient and stable operation of the filter component 2.

[0057] like Figure 5 , Fig. 9 and Fig.13As shown, in addition to the features of the above embodiments, this embodiment further defines that: the cleaning component 4 includes a driving component 41, a mounting component 42 and a cleaning member 43, the driving component 41 is arranged on the inner side wall of the filter component 2, the mounting component 42 is arranged on the driving component 41, the cleaning member 43 is arranged on the mounting component 42 and abuts against the sintered plate 222 of the filter component 2, the mounting component 42 is provided with a clean air inlet hole 401, and the cleaning member 43 is provided with a plurality of clean air blowing holes 402. By arranging the driving component 41 on the inner side wall of the filter component 2, a foundation for installation is provided for the mounting component 42 and the cleaning member 43, ensuring that the driving component 41, the mounting component 42 and the cleaning member 43 can work stably and efficiently. The cleaning member 43 directly contacts the sintered plate 222, and introduces gas through the cleaning air inlet hole and blows it out through a plurality of cleaning air blowing holes, so that the key filtering part of the sintered plate 222 can be accurately and powerfully cleaned, so that each dust-prone area of ​​the sintered plate 222 can be properly cleaned, which greatly improves the cleaning efficiency and effect, ensures that the filter component 2 always maintains good filtering performance, reduces the problem of reduced filtering efficiency due to incomplete cleaning, extends the overall service life of the filter component 2, ensures the stable and efficient operation of the smoke circulation purifier, and reduces the equipment maintenance cost and frequency.

[0058] like Fig. 9 and Fig.10As shown, in addition to the features of the above embodiment, this embodiment further defines that: the driving assembly 41 includes a first motor 411, a first guide rail 412 and a first slider 413, the number of the first guide rails 412 is multiple, the multiple first guide rails 412 are arranged on the filter assembly 2 and extend along the length direction of the filter assembly 2, the first slider 413 is arranged on the multiple first guide rails 412 and extends along the setting direction of the sintering plate 222, the first motor 411 is arranged on the filter assembly 2, the first slider 413 is sleeved on the motor shaft of the first motor 411 and the first slider 413 is connected to the motor shaft of the first motor 411 by transmission, and the mounting assembly 42 is arranged on the first slider 413. By arranging multiple first guide rails 412 on the filter assembly 2 and extending along the length direction of the filter assembly 2, a stable and accurate guide path is provided for the first slider 413, so that the first slider 413 can move smoothly on a predetermined track. The first slider 413 extends along the setting direction of the sintering plate 222, effectively increasing the cleaning coverage and ensuring that the filter assembly 2 is cleaned in all directions. The first motor 411 is arranged on the filter assembly 2 and / or the first slider 413, and can provide a power source for the entire cleaning action, drive the first slider 413 to move flexibly on the first guide rail 412, thereby driving the subsequently connected cleaning components to clean different positions of the filter assembly 2 in an orderly manner. This structural design improves the degree of automation of the cleaning process, does not require a lot of manual intervention, and reduces labor costs and labor intensity. At the same time, the precise movement of the guide rail slider can effectively prevent the cleaning components from causing unnecessary collisions or damage to the filter assembly, extend the service life of the equipment, ensure that the smoke circulation purifier always maintains a good cleaning effect and stable filtering performance during long-term operation, and reduce the replacement frequency of the sintering plate 222.

[0059] like Fig. 9 , Fig.11 , Fig.12 and Fig.13As shown, in addition to the features of the above embodiments, the present embodiment further defines that: the mounting assembly 42 includes a connecting member 421, a spring 422, a second guide rail 423, a second motor 424, a second slider 425 and a vibrator 426, the number of the connecting members 421 is multiple, and the multiple connecting members 421 are movably arranged on the driving assembly 41, the second guide rail 423 is arranged on the multiple connecting members 421 and extends along the setting direction of the sintering plate 222, the number of the springs 422 is multiple, and the multiple springs 422 are clamped in the multiple corresponding positions. A connecting member 421 is provided between the second guide rail 423, a second motor 424 is provided on the second guide rail 423, a second slider 425 is slidably provided on the second guide rail 423, the second slider 425 is sleeved on the motor shaft of the second motor 424 and the second slider 425 is drivingly connected to the motor shaft of the second motor 424, a plurality of vibrators 426 are provided on both sides of the second guide rail 423, a cleaning member 43 is provided on the second slider 425, and the second slider 425 is provided with a cleaning air inlet 401. By closely connecting the plurality of connecting members 421 with the driving assembly 41, the continuity and integrity of the cleaning action are ensured. The second guide rail 423 extends along the direction of the sintering plate 222, providing a track for the second slider 425 to move in a directional manner, making the cleaning operation more directional. The second motor 424 arranged on the second guide rail 423 drives the second slider 425, so that the second slider 425 can move back and forth between the intervals of multiple sintering plates 222, so that the cleaning member 43 arranged on the second slider 425 can be in close contact with the sintering plate 222, so as to achieve the effect of thoroughly cleaning the sintering plate 222.

[0060] like Fig. 9 , Fig.11 and Fig.13As shown, in addition to the features of the above embodiment, this embodiment further defines that: the cleaning member 43 includes a cleaning strip 431 and a cleaning brush 432, the number of the cleaning strips 431 is multiple, and the multiple cleaning strips 431 are arranged along the length direction of the mounting assembly 42, the number of the cleaning brushes 432 is multiple, and the multiple cleaning brushes 432 are arranged circumferentially along the length direction of the cleaning strip 431, and the multiple cleaning brushes 432 are against the sintering plate 222, and the cleaning strip 431 is provided with multiple cleaning blowing holes 402, and the multiple cleaning blowing holes 402 are connected to the cleaning air inlet hole 401, and the multiple cleaning blowing holes 402 are arranged opposite to the sintering plate 222. By arranging the multiple cleaning strips 431 in an orderly manner along the second slider 425, the contact area with the sintering plate 222 is greatly increased, and the sintering plate 222 can be deeply cleaned in all directions and at multiple angles in combination with the numerous cleaning brushes 432 arranged circumferentially on the cleaning strip 431 and the high-frequency vibration of the mounting assembly 42. The cleaning air inlet 401 is connected to the back-blowing air inlet 301 of the back-blowing assembly 3, and the cleaning air inlet 401 is connected to the cleaning air blowing hole 402 on the cleaning strip. While the cleaning brush is physically cleaning, the gas of the back-blowing assembly 3 can be introduced, and the cleaned smoke and dust can be further blown away from the sintering plate 222 by blowing, effectively preventing it from attaching again, thereby improving the cleaning efficiency and quality. This combination of physical cleaning and airflow blowing can thoroughly remove the stubborn smoke and dust on the sintering plate 222, so that the sintering plate 222 always maintains good filtering performance, greatly reducing the risk of equipment operation failure caused by blockage of the sintering plate 222, ensuring the continuous and stable operation of the smoke circulation purifier, extending the service life of the filter assembly 2, reducing equipment maintenance and replacement costs, and providing a solid and powerful guarantee for efficient purification of smoke and dust, especially suitable for industrial smoke and dust treatment fields with high requirements for filtering accuracy and equipment stability.

[0061] like Figure 1 , Figure 7 and Figure 8As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the back-blowing assembly 3 includes an air storage member 31, an electromagnetic valve 32 and a back-blowing bracket 33, the air storage member 31 is arranged on the filter assembly 2, the number of the electromagnetic valves 32 is multiple, and the multiple electromagnetic valves 32 are arranged along the length direction of the air storage member 31, the number of the back-blowing bracket 33 is multiple, and the multiple back-blowing brackets 33 are arranged on the filter assembly 2 and are connected to the multiple electromagnetic valves 32 in a one-to-one correspondence, the electromagnetic valve 32 is provided with a back-blowing air inlet 301, and the back-blowing bracket 33 is provided with a plurality of back-blowing holes 302. By arranging the air storage member 31 on the filter assembly 2, a stable and sufficient gas source is provided for the back-blowing operation, ensuring that the gas can be supplied in time when back-blowing cleaning is required, and maintaining a stable back-blowing pressure. There are multiple solenoid valves 32 arranged along the length direction of the gas storage member 31. The solenoid valves 32 at different positions can independently adjust the gas flow and the on-off state according to actual needs, and accurately perform back-blowing operations on different areas of the filter assembly. Under different working conditions, the back-blowing parameters can be flexibly adjusted through the solenoid valve 32 to adapt to the different cleaning requirements of the filter assembly 2, thereby improving the adaptability and intelligence of the equipment. Multiple back-blowing brackets 33 are connected to the solenoid valves 32 one by one, and are provided with multiple back-blowing holes 302, so that the back-blowing gas can act evenly and efficiently on various parts of the filter assembly 2, effectively removing the smoke and dust attached to the filter medium. This uniform back-blowing distribution avoids the problem of reduced filtering effect caused by uneven local back-blowing, effectively ensures that the filtering efficiency of the filter assembly 2 is always at a high level, prolongs the service life of the filter assembly 2, and reduces the cost and time consumption of frequent replacement or maintenance due to blockage of the filter assembly 2, thereby improving the operating stability and economy of the entire smoke circulation purifier.

[0062] like Figure 1 , Figure 5 and Figure 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the collecting assembly 5 includes a first collecting member 51 and a second collecting member 52, the first collecting member 51 is arranged on the first filter unit 21, and the second collecting member 52 is arranged on the second filter unit 22. By arranging the first collecting member 51 on the first filter unit 21, the large particles of smoke and dust separated by the cyclone separation filter during operation can be accurately collected. Since large particles of smoke and dust usually have a large mass and volume, the first collecting member 51 can effectively prevent them from accumulating or scattering inside the filter, avoiding adverse effects on subsequent filtering links, and facilitating centralized processing and subsequent cleaning, thereby reducing maintenance costs. The second collecting member 52 is located on the second filter unit 22, and is specifically used to collect fine particles of smoke and dust intercepted by the sintered plate filter during the filtering process. It can ensure that these fine particles are properly collected to prevent air pollution caused by secondary dust or pollution of other components inside the equipment. The two collecting parts have their own functions, corresponding to the collection needs of different filtering units respectively, so that the smoke and dust waste generated in the entire filtration process can be collected and managed in an orderly manner, ensuring the cleanliness inside the smoke and dust circulation purifier and the stability of the overall operation, and improving the reliability and environmental protection performance of the equipment.

[0063] like Figure 1 and Figure 3 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the bracket assembly 1 includes a bracket 11, a fan housing 12 and a foot 13, the fan housing 12 is arranged on the bracket 11, the number of the foot 13 is multiple, and the multiple foot 13 is arranged along the circumference of the bracket 11, the filter assembly 2 and the control assembly 6 are arranged on the bracket 11, and the fan assembly 7 is arranged on the fan housing 12. By arranging the filter assembly 2 and the control assembly 6 on the bracket 11, it is ensured that each component remains stable during operation, the risk of failure caused by vibration or displacement is reduced, and the normal operation of the entire purifier is guaranteed. The fan housing 12 is specifically used to house the fan assembly 7, providing a relatively independent and suitable operating space for the fan, which helps to optimize the working environment of the fan, reduce the interference of external factors on the performance of the fan, and facilitate the maintenance and repair of the fan. The plurality of circumferentially arranged feet 13 can, on the one hand, effectively cushion the vibration generated during the operation of the equipment, reduce noise, and improve the stability and comfort of the equipment operation; on the other hand, the feet can adjust the height of the equipment to adapt to different ground conditions of the installation site, and ensure the horizontality and stability of the equipment installation.

[0064] like Figure 1 and Figure 3As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the bracket assembly 1 also includes a pulley 14, the number of pulleys 14 is multiple, and the multiple pulleys 14 are arranged along the circumference of the bracket 11 of the bracket assembly 1. By distributing the multiple pulleys 14 along the circumference of the bracket 11, the device has good mobility. When installing and adjusting the layout of the equipment, it is only necessary to adjust the height of the foot 13, and the operator can easily push the smoke circulation purifier to the designated position without the need for large-scale handling tools, which greatly saves manpower and time costs.

[0065] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: it also includes a protection component 8, which is connected to the filter component 2 through a pipeline. By connecting the protection component 8 and the filter component 2 through a pipeline, inert particles can be flushed into them. During the filtering process, when active particles are filtered out, the inert particles can effectively prevent these active particles from contacting and reacting with each other. This measure greatly reduces the safety risks such as explosion and combustion that may be caused by the reaction of active particles, and ensures the safe and stable operation of the equipment. At the same time, since the new substances generated by the reaction of active particles are avoided from corroding, clogging or contaminating the filter component 2, the service life of the filter component 2 is significantly extended, and the cost and maintenance workload of frequently replacing the filter component 2 are reduced. Moreover, a stable filtering environment helps to maintain the efficiency and sustainability of the entire purification process, ensure that the smoke circulation purifier can always purify the smoke with good performance, improve the reliability and adaptability of the equipment when processing smoke containing active particles, and provide a safer and more reliable smoke purification solution for related industrial production or special environment applications.

[0066] like Figure 1 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the smoke circulation purifier is welded with stainless steel material. By using multiple stainless steel plates to weld the shell and other structures of the smoke circulation purifier, spot welding can accurately control the size and spacing of the welding points, effectively reduce the welding gap, and greatly reduce the possibility of gas leakage. This good sealing property allows the dust-containing gas to flow only along a predetermined path, avoiding gas escape and polluting the surrounding environment or affecting the filtering effect. Whether under high pressure or long-term operation, a stable sealing state can always be maintained, ensuring the stability of the working environment inside the sintered plate filter and improving the overall filtering performance and reliability.

[0067] like Figure 1As shown, in addition to the features of the above embodiment, this embodiment further defines that: the smoke circulation purifier is made of stainless steel material connected by bolts. By fixing multiple stainless steel plates with bolts, accurate tightening force adjustment can be achieved, so that the stainless steel plates fit closely, effectively fill small gaps, and greatly reduce gas leakage channels.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
