Abstract
Description
Technical Field
[0001] This application relates to the field of air purification technology, and in particular to a horizontal anti-bridging device for tobacco dust removal systems. Background Technology
[0002] With air pollution worsening, environmental protection has become a global concern. How to quickly and effectively prevent and control air pollution and achieve a clean air environment is a topic of increasing interest. Clean air systems are especially essential in factories with high dust levels.
[0003] In common dust control devices (such as those in tobacco dust removal systems), different filter cartridges are often used side-by-side. However, over long-term use, this arrangement not only leads to the accumulation of dust and foreign matter on the filter cartridge surfaces, but also causes bridging between the cartridges due to excessive dust and debris buildup. This bridging phenomenon blocks the air vents inside the filter cartridges, making it difficult to effectively remove dust and foreign matter. Consequently, the cleaning efficiency of the device decreases, requiring regular manual cleaning of the bridging, resulting in low overall work efficiency.
[0004] In some of the existing publicly available dust treatment devices, an air blowing branch pipe is designed above the top of the filter element assembly for purging. However, this design cannot effectively purify the lower filter element. Furthermore, since the filter plate grooves of the filter element extend horizontally, the downward airflow cannot effectively purify the surface grooves of the filter element, resulting in an unsatisfactory purging effect.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] In the description of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "second" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] This application provides, as follows: Figures 1-3 Example 1 Figure 4 Example 2 Figure 5 Example 3 Figure 6 Example 4 Figure 7 The technical solution of the horizontal anti-bridging device for the tobacco dust removal system shown in Example 5 is as follows:
[0030] The horizontal anti-bridging device of the tobacco dust removal system includes a housing 300, a filter element 200, and an air blowing module 100. The surface of the filter element 200 is provided with several parallel grooves 210. Multiple filter elements 200 are arranged vertically at intervals in the housing 300 so that the grooves 210 extend horizontally. The air blowing module 100 includes a main pipe 110 and a first air blowing branch pipe 120 connected to the main pipe 110. The main pipe 110 is vertically arranged in the space between adjacent filter elements 200, and several first air blowing branch pipes 120 are arranged at intervals along the vertical direction of the main pipe 110 so that the air blowing direction of the air outlet of the several first air blowing branch pipes 120 is towards the space between the filter elements.
[0031] like Figures 1-3 Example 1 Figure 4 Example 2 Figure 5 Example 3 Figure 6 Example 4 Figure 7As shown in Example 5, specifically, after long-term use, dust and other foreign objects accumulate, causing the space between different filter elements 200 to be blocked by dust and other foreign objects. In this case, this embodiment of the application provides a vertically arranged main pipe 110 within the space formed by adjacent filter elements 200. Multiple first air-blowing branch pipes 120 are arranged vertically from top to bottom on the main pipe 110. Therefore, the air-blowing module 100 can be controlled to blow air towards the space. Furthermore, through the arrangement design of the multiple first air-blowing branch pipes 120, air can be blown into a single... Simultaneously, dust removal is performed on different locations within the interval space along the pipeline path. The air blowing range is distributed vertically from top to bottom, providing a wide range that effectively cleans the lower filter element 200, solving the problem of difficulty in effectively cleaning the lower filter element 200 and minimizing the occurrence of "bridging" phenomenon, while also improving work efficiency. Furthermore, since the filter plate grooves 210 of the filter element 200 extend horizontally, the airflow direction of the first air blowing branch pipe 120 can effectively clean the surface grooves 210 of the filter element 200, resulting in a good cleaning effect.
[0032] In summary, by controlling the blowing module 100 to blow air towards the interval space, those skilled in the art can adjust the gas pressure according to the actual situation. Through pneumatic means, dust or foreign objects accumulated in the interval space can be removed efficiently from multiple directions, thereby solving the "bridging" problem.
[0033] It should be noted that the air blowing module 100 can be connected to a corresponding control module (such as a PLC controller) or a gas supply source such as an air pump or air tank, depending on the situation. The air blowing state is controlled by controlling the state of the air pump or air tank through the control system. In addition, the connection of the control module and the gas supply source are things that can be implemented by those skilled in the art based on the inventive concept, and therefore will not be described in detail.
[0034] This application, by setting an air blowing module 100 in the interval space formed by the filter element 200, can effectively clean the filter element 200 by pneumatic means. In particular, it uses multiple first air blowing branch pipes 120 arranged in sequence along the vertical direction in the interval space to clean the filter element 200, which significantly improves the cleaning effect, thereby ensuring the cleaning efficiency of dust removal and other equipment, solving the "bridging" phenomenon formed between the filter elements 200, and at the same time, the cleaning process does not require regular manual operation, improving work efficiency and having important practical application value.
[0035] Optionally, the main pipe 110 is located on one side of the filter element 200; a plurality of first air blowing branches 120 are arranged at equal intervals along the vertical direction of the main pipe 110, and the pipe path of each first air blowing branch 120 extends in the horizontal direction.
[0036] like Figures 1-3 Example 1 Figure 4As shown in Example 2, the main pipe 110 is located on one side of the filter element 200, and several first air blowing branches 120 are arranged at equal intervals. The pipe path of each first air blowing branch 120 extends in the horizontal direction. This design helps to improve the uniformity and coverage of the air blowing range, further improve the cleaning effect, and thus ensure the cleaning efficiency of dust removal and other equipment.
[0037] Optionally, the first air blowing branch pipe 120 is connected to the main pipe 110 via a first universal joint 122, so that the air blowing direction of the air outlet of the first air blowing branch pipe 120 can be adjusted.
[0038] like Figure 4 Example 2 Figure 5 Example 3 Figure 6 Example 4 Figure 7 As shown in Example 5, dust or foreign objects may be firmly adhered to certain areas on the surface of the filter element 200. By setting the first universal joint 122, the blowing direction of the air outlet of the first air blowing branch pipe 120 can be adjusted, thereby enabling targeted air blowing cleaning of certain areas, which helps to further improve the cleaning effect and thus ensure the cleaning efficiency of dust removal and other equipment.
[0039] It should be noted that the first universal joint 122 can be selectively connected to a corresponding control module (such as a PLC controller) as needed. The control module controls the rotation of the first universal joint 122 to adjust the air blowing direction. In addition, the first universal joint 122 is an existing device, and the connection and control between the first universal joint 122 and the control module can be implemented by those skilled in the art based on the inventive concept, so it will not be described in detail.
[0040] Optionally, the first air blowing branch pipe 120 is detachably connected to the main pipe 110 via a first universal joint 122.
[0041] like Figure 4 Example 2 Figure 5 Example 3 Figure 6 Example 4 Figure 7 As shown in Example 5, a detachable connection is provided to facilitate the replacement and maintenance of the first air blowing branch pipe 120 and the first universal joint 122.
[0042] Optionally, the first air-blowing branch pipe 120 includes a first inward branch pipe 120a, a first parallel branch pipe 120b, and a first outward branch pipe 120c; the extension direction of the first parallel branch pipe 120b is parallel to the surface of the filter element 200; the first inward branch pipe 120a extends inward so that the air-blowing direction of the first inward branch pipe 120a faces the surface of the inner filter element 200 among the adjacent filter elements 200; the first outward branch pipe 120c extends outward so that the air-blowing direction of the air-blowing port of the first outward branch pipe 120c faces the surface of the outer filter element 200 among the adjacent filter elements 200. Optionally, the first inward branch pipe 120a, the first parallel branch pipe 120b, and the first outward branch pipe 120c are arranged sequentially and cyclically along the vertical direction of the main pipe 110; the included angle formed by the first inward branch pipe 120a and the first outward branch pipe 120c is greater than 60° and less than 120°.
[0043] like Figure 7 As shown in Example 5, the first air blowing branch pipe 120 is arranged in sequence with a first inward branch pipe 120a, a first parallel branch pipe 120b, and a first outward branch pipe 120c, so that the surface of the filter element 200 can be blown in multiple directions, including inward, outward, and horizontal, thereby improving the cleaning effect and ensuring the cleaning efficiency of dust removal and other equipment.
[0044] Furthermore, in conjunction with the design of the first universal joint 122, the same first air blowing branch pipe 120 can be reversed in direction. For example, if the original arrangement of the three first air blowing branch pipes 120 is as follows: first inward branch pipe 120a, first parallel branch pipe 120b, and first outward branch pipe 120c, it can be adjusted to the following arrangement: first parallel branch pipe 120b, first outward branch pipe 120c, and first inward branch pipe 120a. Then, it can be adjusted again to the following arrangement: first outward branch pipe 120c, first inward branch pipe, and first parallel branch pipe 120b. This regular, multi-directional blowing further improves the cleaning effect and increases work efficiency.
[0045] Optionally, the filter element 200 is provided with a micro vibration device 400.
[0046] like Figure 6 As shown in Example 4, the filter element 200 is equipped with a micro vibration device 400. The micro vibration device 400 slightly vibrates and shakes off dust and other foreign objects on the filter element 200. Combined with air blowing, the cleaning effect is further improved and the work efficiency is increased.
[0047] It should be noted that the micro vibration device 400 can be connected to a corresponding control module (such as a PLC controller) as needed, and the operation of the micro vibration device 400 can be controlled by the control module. In addition, the micro vibration device 400 is an existing device, and the connection and control between the micro vibration device 400 and the control module can be implemented by those skilled in the art based on the inventive concept, so it will not be described in detail.
[0048] Optionally, the first air blowing branch pipe 120 is provided with a first control valve 121.
[0049] like Figure 7 As shown in Example 5, the gas flow rate and pressure can be controlled by the first control valve 121. The air blowing module 100 or the first control valve 121 can be connected to technologies known in the art, air pumps or air tanks, and corresponding control modules (such as PLC controllers). Preferably, the first control valve 121 is a pulse valve, which enables pulse cleaning and further improves cleaning efficiency.
[0050] Optionally, in the vertical direction, multiple sets of filter elements 200 are arranged from top to bottom inside the housing 300; each set of filter elements 200 includes multiple filter elements 200 arranged at intervals.
[0051] like Figure 1 As shown, multiple sets of filter elements 200 can be set in the vertical direction according to actual needs, and each set of filter elements 200 can also be equipped with multiple sets of filter element 200 fixing structures.
[0052] Optionally, it also includes a fixing mechanism 130; the fixing mechanism 130 is used to detachably and fix the main pipe 110 to the chassis 300.
[0053] In summary, the horizontal anti-bridging device for the tobacco dust removal system provided in this application has the following beneficial effects:
[0054] By setting an air blowing module 100 in the interval space formed by the filter element 200, the filter element 200 can be effectively cleaned pneumatically. In particular, multiple first air blowing branch pipes 120 arranged vertically in the interval space are used to clean the filter element 200, which significantly improves the cleaning effect and ensures the cleaning efficiency of dust removal equipment. It solves the "bridging" phenomenon formed between filter elements 200. At the same time, the cleaning process does not require regular manual operation, which improves work efficiency and has important practical application value.

These terms are used merely for the convenience of describing and explaining the nature of this application; interpreting them as any additional limitation would be contrary to the spirit of this application.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
