Description

Technical Field

[0001] This application relates to the field of air purification technology, and in particular to a novel anti-bridging device for 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 systems, different filter cartridges are used side-by-side. However, over time, this arrangement leads to dust and debris accumulation on the filter surfaces, and the spaces between different cartridges can become bridging 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 debris. Consequently, the system's cleaning efficiency 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

[0028] 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.

[0029] 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.

[0030] This application provides, as follows: Figure 1-3 Example 1 Figure 4 Example 2 Figure 5 Example 3 Figure 6 Example 4 Figure 7 The technical solution of the novel anti-bridging device for the dust removal system shown in Example 5 is as follows:

[0031] The novel dust removal system's anti-bridging device includes a housing 300, filter elements 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 vertically spaced within the housing 300, so that the grooves 210 extend horizontally. The air blowing module 100 includes a main pipe 110, a first air blowing branch pipe 120 connected to the main pipe 110, a connecting pipe 140, and a second air blowing branch pipe 150 connected to the connecting pipe 140. The main pipe 110 is vertically arranged adjacent to the filter elements 200. Within the space formed by the filter elements 200, a plurality of first air-blowing branch pipes 120 are arranged sequentially at intervals along the vertical direction of the main pipe 110, such that the air-blowing direction of the air outlets of the plurality of first air-blowing branch pipes 120 faces the space; the connecting pipe 140 is connected to the main pipe 110 and is horizontally arranged within the space formed by adjacent filter elements 200; a plurality of second air-blowing branch pipes 150 are arranged sequentially at intervals along the horizontal direction of the connecting pipe 140, such that the air-blowing direction of the air outlets of the plurality of second air-blowing branch pipes 150 faces the space.

[0032] like Figure 1-3 Example 1 Figure 4 Example 2 Figure 5 Example 3 Figure 6 As shown in Example 4, 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.

[0033] In addition, multiple second air blowing branches 150 arranged in sequence along the horizontal direction in the interval space are provided to help blow air from above the filter element 200 to clean the filter element 200 from one side to the other, further expanding the air blowing range, improving the cleaning effect, and increasing work efficiency.

[0034] 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.

[0035] 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.

[0036] 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 pneumatically. Specifically, it uses multiple first air blowing branch pipes 120 arranged vertically in the interval space and multiple second air blowing branch pipes 150 arranged horizontally 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 the cleaning process does not require regular manual operation, thus improving work efficiency and having important practical application value.

[0037] Optionally, such as Figure 7 As shown in Example 5, a plurality of connecting pipes 140 are spaced apart on the main pipe 110, and a plurality of second air-blowing branch pipes 150 are arranged sequentially at intervals along the horizontal direction of the connecting pipes 140. This design is beneficial for further expanding the air-blowing range, improving the cleaning effect, and increasing work efficiency.

[0038] Optionally, the main pipe 110 is located at one side of the filter element 200, and the connecting pipe 140 is located at the top edge of the filter element 200; a plurality of first air blowing branch pipes 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 pipe 120 extends in the horizontal direction; a plurality of second air blowing branch pipes 150 are arranged at equal intervals along the horizontal direction of the connecting pipe 140, and the pipe path of each second air blowing branch pipe 150 extends in the vertical direction.

[0039] like Figure 1-3As shown in Example 1, 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.

[0040] Similarly, several second air-blowing branch pipes 150 are arranged at equal intervals along the horizontal direction of the connecting pipe 140, and the pipe path of each second air-blowing branch pipe 150 extends vertically. This helps to improve the uniformity and coverage of the air-blowing area, further improving the cleaning effect and thus ensuring the cleaning efficiency of dust removal and other equipment.

[0041] 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 is adjustable; the second air blowing branch pipe 150 is connected to the connecting pipe 140 via a second universal joint 142, so that the air blowing direction of the air outlet of the second air blowing branch pipe 150 is adjustable.

[0042] like Figure 4 Example 2 Figure 5 As shown in Example 3, 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 and the second universal joint 142, the air blowing direction of the air outlet of the first air blowing branch pipe 120 and the second air blowing branch pipe 150 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.

[0043] It should be noted that the first universal joint 122 and the second universal joint 142 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 and the second universal joint 142 to adjust the air blowing direction. Furthermore, the first universal joint 122 and the second universal joint 142 are existing devices, and the connection and control between the first universal joint 122 and the second universal joint 142 and the control module can be implemented by those skilled in the art based on this inventive concept; therefore, it will not be elaborated further.

[0044] Optionally, the first air blowing branch pipe 120 is detachably connected to the main pipe 110 via a first universal joint 122; the second air blowing branch pipe 150 is detachably connected to the connecting pipe 140 via a second universal joint 142; and the connecting pipe 140 is detachably connected to the main pipe 110.

[0045] like Figure 4 Example 2 Figure 5Example 3 Figure 6 As shown in Example 4, the design allows for detachable connections, facilitating the replacement and maintenance of the first air blowing branch pipe 120 and the second air blowing branch pipe 150, the first universal joint 122 and the second universal joint 142.

[0046] Optionally, the first air blowing branch pipe 120 is provided with a first control valve 121; optionally, the connecting pipe 140 is provided with a second control valve 141, and / or, the second air blowing branch pipe 150 is provided with a second control valve 141.

[0047] like Figure 5 As shown in Example 3, the gas flow rate and pressure can be controlled by the first control valve 121 and the second control valve 141. The air blowing module 100 or the first control valve 121 and the second control valve 141 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 and the second control valve 141 are pulse valves, which enable pulse cleaning and further improve cleaning efficiency.

[0048] 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 is towards 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 is towards the surface of the outer filter element 200 among the adjacent filter elements 200. The second air-blowing branch pipe 150 includes a second inward branch pipe 140a, a second parallel branch pipe 140b, and a second outward branch pipe 140c; the extension direction of the second parallel branch pipe 140b is parallel to the surface of the filter element 200; the second inward branch pipe 140a extends inward so that the air-blowing direction of the second inward branch pipe 140a is toward the surface of the inner filter element 200 among the adjacent filter elements 200; the second outward branch pipe 140c extends outward so that the air-blowing direction of the air-blowing port of the second outward branch pipe 140c is toward the surface of the outer filter element 200 among the adjacent filter elements 200. Optionally, a first inward branch pipe 120a, a first parallel branch pipe 120b, and a 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°; a second inward branch pipe 140a, a second parallel branch pipe 140b, and a second outward branch pipe 140c are arranged sequentially and cyclically along the horizontal direction of the connecting pipe 140; the included angle formed by the second inward branch pipe 140a and the second outward branch pipe 140c is greater than 60° and less than 120°.

[0049] like Figure 4 Example 2 Figure 5 As shown in Example 3, 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.

[0050] 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.

[0051] Similarly, the second blowing branch pipe 150 adopts the second inward branch pipe 140a, the second parallel branch pipe 140b, and the second outward branch pipe 140c arranged in sequence to achieve the same effect as described above.

[0052] Optionally, the filter element 200 is provided with a micro vibration device 400.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] like Figure 1-3 As shown in Example 1, 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 provided with multiple sets of filter element 200 fixing structures.

[0057] 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.

[0058] In summary, the novel anti-bridging device for dust removal systems provided in this application has the following beneficial effects:

[0059] 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. It uses multiple first air blowing branch pipes 120 arranged vertically in the interval space and multiple second air blowing branch pipes 150 arranged horizontally in the interval space 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.

[0060] Although this document uses terms such as filter element and air blowing module frequently, the possibility of using other terms is not excluded. 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.

[0061] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
