[0026] like Figure 1-2 As shown, the present application provides an exhaust gas filter cleaning device, including an exhaust pipe 1, a housing 2, a filter cartridge 3, an acceleration tube 4, a settling chamber 5 and an exhaust pipe 6 connected in sequence. The exhaust pipe 1 is used to be connected to the exhaust gas conveying pipeline of a tobacco production process such as a cigarette making machine, and can transport the generated exhaust gas to the housing 2 for treatment. The filter cartridge 3 is used for the preliminary separation of exhaust gas and tobacco raw materials, and tobacco particles of smaller size can enter from the filter cartridge 3, while tobacco particles of larger size are isolated in the housing 2 by the filter cartridge 3. The acceleration tube 4 is used to accelerate the exhaust gas and small-sized tobacco particles flowing through, so that the tobacco particles can be smoothly settled in the settling chamber 5. The settling chamber 5 is used to separate small-sized tobacco particles from the exhaust gas. The exhaust pipe 6 is used to discharge the separated exhaust gas to the exhaust system. When the filter cartridge 3 filters larger-sized tobacco particles such as shredded tobacco and tobacco stems, the shredded tobacco and tobacco stems are easily attached to the surrounding side of the filter cartridge 3, resulting in poor exhaust gas circulation, and the exhaust gas and tobacco particles cannot be separated, and the filtering effect is poor. It is worth noting that the driving source for the flow of exhaust gas in the device comes from the exhaust system connected to the exhaust pipe 6, and the present application does not require the provision of additional components such as a compressor.

[0027] In the present application, both ends of the filter cartridge 3 are rotatably connected to the acceleration tube 4 and the housing 2, respectively. The filter cartridge 3 is provided with a through filter hole 31, and the filter hole 31 is used to separate the exhaust gas entering the housing 2 and the small-sized tobacco particles that can pass through the filter hole 31 from the large-sized tobacco particles. A first cleaning component 7 is provided on the peripheral side of the filter cartridge 3. The first cleaning component 7 includes a mounting seat 71 arranged near the peripheral side of the filter cartridge 3. The mounting seat 71 is fixedly connected to the housing 2. A purge channel 72 for purging the peripheral side of the filter cartridge 3 is provided in the mounting seat 71. An air supply pipe 73 is provided at one end of the mounting seat 71 close to the housing 2 along the length direction. The air supply pipe 73 is connected to the purge channel 72, and is used to fill the purge channel 72 with gas, and the purge channel 72 purges the peripheral side of the filter cartridge 3. One end of the air supply pipe 73 located outside the housing 2 is connected to a compressor. It is worth noting that, if Figure 3 , the projection area of ​​the purge channel 72 in the length direction increases in the direction close to the gas pipe 73, so as to ensure that the purge channel 72 can also purge the surrounding side of the filter cartridge 3 away from the gas pipe 73. When large-sized tobacco particles or tobacco shreds are attached to the surrounding side of the filter cartridge 3, they are removed from the surrounding side of the filter cartridge 3 by blowing during the process of the filter cartridge 3 rotating to the vicinity of the purge channel 72. A scraper 74 is provided at the purge port of the mounting seat 71 close to the purge channel 72. One end of the scraper 74 is connected to the mounting seat 71, and the other end abuts against the filter cartridge 3. In this way, during the rotation of the filter cartridge 3, the scraper 74 can scrape off the tobacco shreds or large-sized tobacco particles attached to the surrounding side of the filter cartridge 3, which is beneficial to the subsequent cleaning of the purge channel 72.

[0028] A second cleaning assembly 8 is also provided in the filter cartridge 3. Figure 4 and Figure 5 , the second cleaning assembly 8 includes a stator 81 and a connecting rod 82. The stator 81 can be a columnar structure with a bottom surface of one-tenth of a circular surface. The stator 81 is connected to the peripheral side of the connecting rod 82. The connecting rod 82 is arranged on the axis of the filter cartridge 3. The stator 81 and the connecting rod 82 are both hollow structures and are interconnected. The connecting rod 82 is arranged at the axis of the filter cartridge 3. One end of the connecting rod 82 is arranged in the filter cartridge 3 and connected to the stator 81, and the other end passes through the box body 2 and is connected to the compressor arranged outside the box body 2. The length of the stator 81 is arranged in accordance with the filter cartridge 3. A purge groove 83 arranged along the length direction is provided on one side of the stator 81 close to the filter cartridge 3. When the compressor inflates the connecting rod 82, the gas passes through the connecting rod 82, the stator 81 and the purge groove 83 in sequence, and then the inner wall of the filter cartridge 3 is purged, so that some of the tobacco shreds and large-sized tobacco particles stuck in the filter hole 31 can be blown out back into the box body 2. Of course, it is also possible to remove some of the tobacco shreds attached to the peripheral side of the filter cartridge 3 near the filter hole 31. When the filter cartridge 3 rotates, the purge slot 83 cleans the inner wall of the entire filter cartridge 3.

[0029] The filter cartridge 3 is a coverless structure at both ends, which is respectively connected to the acceleration tube 4 and the housing 2. A drive shaft 32 is arranged at the axis center of the filter cartridge 3 near one end of the housing 2. The drive shaft 32 is sleeved on the peripheral side of the connecting rod 82. When the drive shaft 32 rotates, the connecting rod 82 and the stator 81 do not rotate. A plurality of drive rods 33 are arranged on the peripheral side of the drive shaft 32 near one end of the filter cartridge 3. One end of the drive rod 33 is fixedly connected to the drive shaft 32, and the other end is connected to the filter cartridge 3. When the drive rod 33 rotates, it can drive the filter cartridge 3 to rotate around the axis center. The drive rod 33 is connected to a motor through the housing 2 at one end away from the filter cartridge 3, and the motor drives the drive rod 33 to rotate.

[0030] The diameter of the accelerating tube 4 increases linearly or nonlinearly in the direction close to the filter cartridge 3, so that when the exhaust gas and small-sized tobacco particles are only, they can be accelerated, so that the small-sized tobacco particles collide with the inner wall of the settling chamber 5, which is convenient for the tobacco particles to settle and realize the separation of the exhaust gas and the small-sized tobacco particles. The top of the settling chamber 5 is connected to the exhaust pipe 6, and the bottom of the settling chamber 5 is provided with a recovery box 9. The settled small-sized tobacco particles fall into the recovery box 9 for collection, and the exhaust gas reaches the exhaust system through the exhaust pipe 6.

[0031] The method of using the utility model is as follows:

[0032] When the exhaust gas flows through the filter cartridge 3, large-sized tobacco shreds or tobacco stems and other raw materials are filtered, and some of the tobacco shreds or tobacco stems will return to the box body 2, and some will adhere to the surface of the filter cartridge 3. During the process of the filter cartridge 3 rotating around the axis, the first cleaning component 7 will blow and clean the surrounding side of the filter cartridge 3, and the second cleaning component 8 will blow and clean the filter hole 31, and the linear blowing ports of the two will not affect the overall negative pressure suction filtration of the filter cartridge 3. The purged tobacco shreds, tobacco stems and other raw materials will return to the box body for recycling. In this way, the problem of easy clogging of the filter device is optimized while filtering and recycling the raw materials, and a sedimentation chamber is provided to perform secondary separation and recovery of small-sized tobacco particles passing through the filter cartridge 3, thereby improving the recovery efficiency of tobacco raw materials.
