Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to an exhaust gas particle settling device. Background Art

[0002] In order to further adapt to the development strategy of large-scale tobacco planting, intensive management, specialization of division of labor, and information management in my country, we should cultivate special tobacco leaves that meet the development of Chinese cigarette brands according to the requirements of modern tobacco agriculture, and develop high-efficiency and energy-saving baking equipment with core technology and independent intellectual property rights. Although most tobacco manufacturing workshops can recover wet heat during the baking process, the recovery of effective ingredients in the materials discharged from the air outlet of the tobacco manufacturing workshop is relatively small. Especially when using cigarette making machines to make cigarettes, small-sized tobacco particles, due to their low quality, often reach the exhaust gas flow in the cigarette making machine, and these tobacco particles account for a large part of the total tobacco input in cigarette manufacturing, which undoubtedly causes a waste of tobacco raw materials. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide an exhaust gas particle settling device, so that it can solve the problem of tobacco particle waste caused by exhaust gas emissions.

[0004] The utility model solves the above technical problems through the following technical means:

[0024] In the conventional design, the exhaust pipe 1 is directly connected to the exhaust system, and the waste gas generated by the cigarette making machine and some small tobacco particles are directly discharged, resulting in a waste of raw materials. Figure 1-3 As shown, the present application provides a waste gas particle settling device, which is arranged between the exhaust pipe 1 of the cigarette making machine and the exhaust system of tobacco production. The device includes an installation box 2. The installation box 2 is a cavity structure, which is used to connect with the exhaust pipe 1 and is also used to install other components in the device. A filter cartridge 21, an acceleration tube 22 and a sedimentation chamber 23 are arranged in the installation box 2. The filter cartridge 21 is used to draw in the waste gas and tobacco particles in the installation box 2 and filter larger materials such as tobacco. The acceleration tube 22 is used to accelerate the passing waste gas and tobacco particles so that they hit the inner wall of the sedimentation chamber 23, so that the tobacco particles can be settled there. The sedimentation chamber 23 is used as an area for separating waste gas and tobacco particles, and can collect the settled tobacco particles. A connecting pipe 231 is arranged at the top of the sedimentation chamber 23 for the waste gas with lower density to flow out from it to the waste gas system. A collection pipe 232 is arranged at the bottom of the sedimentation chamber 23 for the recovery of tobacco particles.

[0025] Specifically, the filter cartridge 21 is a cylinder without a cover at both ends, one end of which is connected to the inner wall of the mounting box 2, and the other end is connected to the acceleration tube 22. The acceleration tube 22 is connected to the sedimentation chamber 23 at one end away from the filter cartridge 21. The peripheral side of the filter cartridge 21 is provided with a connecting hole for the entry of exhaust gas and tobacco particles. Of course, the filter cartridge 21 can also filter larger-sized substances in the exhaust gas, such as tobacco shreds, tobacco stems, etc. The acceleration tube 22 is a truncated cone-shaped structure, and its inner diameter decreases linearly or nonlinearly along the transportation direction of the exhaust gas and tobacco particles. When the exhaust gas and tobacco particles pass through the acceleration tube 22, due to the narrowing of the acceleration tube 22, the speed of the exhaust gas and tobacco particles will continue to increase, which is convenient for the sedimentation of the tobacco particles. When the unaccelerated exhaust gas and tobacco particles flow through the sedimentation chamber 23, the sedimentation chamber 23 acts as a connector, and only a small amount of tobacco particles settle here, and most of the tobacco particles enter the connecting pipe 231 driven by the exhaust gas flow to reach the exhaust system. In the present application, an acceleration tube 22 is provided to accelerate the tobacco particles and exhaust gas flowing through, so that the tobacco particles can fully hit the inner wall of the sedimentation chamber 23. Under the friction force of the inner wall of the sedimentation chamber 23, the tobacco particles cannot or have difficulty in overcoming the friction force and rise to the connecting tube 231, and finally fall under their own gravity to the bottom of the sedimentation chamber 23. It is worth noting that the source of driving the movement of the exhaust gas and tobacco particles in the present application lies in the negative pressure system in the connecting tube 231. The exhaust gas and tobacco particles flow through the installation box 2, the filter cartridge 21, and the acceleration tube 22 in sequence and then reach the sedimentation chamber 23. The tobacco particles are recovered at the sedimentation chamber 23, and the exhaust gas continues to flow through the connecting pipe to reach the exhaust system.

[0026] A mounting plate 25 is also provided in the mounting box 2 at the connection between the accelerating tube 22 and the filter cartridge 21. The mounting plate 25 is used to improve the connection stability between the accelerating tube 22 and the filter cartridge 21 in the mounting box 2.

[0027] The device also includes a recovery cylinder 24 arranged at the collecting pipe 232. The settling chamber 23 is a continuous or discontinuous closing structure downward in the height direction, so that the tobacco particles can slide down to the bottom along the inclined inner wall. The collecting pipe 232 arranged at the bottom of the settling chamber 23 can guide the tobacco particles to fall into the recovery cylinder 24 so as to recycle the tobacco particles. The recovery cylinder 24 and the collecting pipe 232 are connected in a detachable manner, so that when the tobacco particles in the recovery cylinder 24 are fully collected, the recovery cylinder 24 can be removed to recycle the tobacco particles.

[0028] like Figure 3, the recovery tube 24 and the collection tube 232 can be set to a sliding engagement connection structure. The recovery tube 24 is provided with a block 241 on the periphery, and the collection tube 232 is provided with an L-shaped hole 233. When the recovery tube 24 is connected to the collection tube 232, the block 241 can be engaged in the L-shaped hole 233. Preferably, the recovery tube 24 and the collection tube 232 can also be connected by a mutually meshing threaded structure. To ensure the sealing of the connection, multiple annular sealing strips are provided on the inner wall of the collection tube 232.

[0029] A maintenance window 3 is provided on the side wall of the installation box 2. The maintenance window 3 is connected to the installation box 2 in an openable and closable manner. The connection between the two can be hinged, slidably connected, etc. In this way, it is convenient for maintenance personnel to maintain the components in the installation box 2 through the maintenance window 3, such as replacing the recovery cylinder 24, cleaning the filter cylinder 21, etc.

[0030] The method of using the utility model is as follows:

[0031] In this application, the negative pressure of the original exhaust system is used as the power to drive the waste gas and tobacco particles in the cigarette making machine to flow through the exhaust pipe 1, the installation box 2, the filter cartridge 21, the acceleration tube 22 to the sedimentation chamber 23. The filter cartridge 21 can filter large-sized substances such as tobacco and leave them in the installation box 2. The tobacco particles accelerated by the acceleration tube 22 can hit the inner wall of the sedimentation chamber 23 and fall into the recovery tube 24 under the guidance of the narrowing structure of the sedimentation chamber 23. The waste gas flowing through the sedimentation chamber 23 finally enters the exhaust system through the connecting pipe 231. In this way, the purpose of recovering tobacco particles in the waste gas is achieved.

[0032] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
