Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, specifically a medium-efficiency bag filter. Background Technology

[0002] Medium-efficiency bag filters primarily remove particulate matter from the air through physical filtration, offering good air permeability and a certain level of filtration accuracy. They are widely used and are indispensable environmental protection equipment in industries such as electronics, pharmaceuticals, and food processing.

[0003] A medium-efficiency bag filter assembly, as described in patent document CN213853565U, includes a mother frame and a sub-frame. The mother frame is a first planar rectangular structure formed by connecting several U-shaped inner grooves. Several parallel partitions are arranged along the transverse or longitudinal direction of the first planar rectangular structure. The sub-frame is a second planar rectangular structure formed by connecting several aluminum edges. Each aluminum edge of the sub-frame can be embedded into the inner groove of the mother frame. Several reinforcing ribs are arranged in the direction parallel to the partitions in the second planar rectangular structure. The two ends of each reinforcing rib are fixedly connected to the flanges extending from the aluminum edges of the adjacent sub-frames, and their positions correspond one-to-one with the positions of the partitions on the mother frame. This utility model provides a medium-efficiency bag filter assembly that is easy to disassemble and allows for convenient replacement of the filter bag.

[0004] The aforementioned technologies suffer from the problem of inconvenient filter bag disassembly. If the disassembly or installation of the filter bag is cumbersome, requiring specialized tools or complex steps, then each replacement or cleaning of the filter bag will consume a significant amount of time and manpower. This undoubtedly increases the maintenance burden and may affect production efficiency. Furthermore, pollutants such as dust, particulate matter, and oil mist in the air will continuously accumulate on the surface of the filter bag. If it cannot be disassembled for cleaning or replacement in a timely and convenient manner, these pollutants will quickly clog the pores of the filter bag, severely hindering airflow. Filter bag clogging directly leads to a decrease in its filtration capacity, making it unable to effectively capture pollutants. This means that unfiltered air will directly enter subsequent stages, increasing the risk of pollution and seriously affecting the performance of the entire filtration system. Utility Model Content

[0005] The purpose of this invention is to provide a medium-efficiency bag filter to solve the problem of inconvenience in disassembling the filter bag in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0016] In one alternative: both the first and second hook and loop fasteners are made of polyester fiber material.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The outer frame of this utility model can be made of aluminum alloy profile, galvanized frame or stainless steel frame, which can effectively meet the needs of specific places. Aluminum alloy profile is relatively commonly used.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figures 1-3 As shown, a medium-efficiency bag filter includes an outer frame 100 and a filter element. The filter element includes several support frames 200, all of which are disposed inside the outer frame 100. The outer frame 100 also contains several finished chemical fiber bags 300. Each finished chemical fiber bag 300 has a hook 400 on its top, and the hooks 400 are mounted on the support frames 200. By placing the hooks 400 on the support frames 200, the finished chemical fiber bags 300 are secured. The finished chemical fiber bags 300 can filter particulate matter. When it is necessary to disassemble and clean the finished chemical fiber bags 300, the bags can be moved directly, causing the hooks 400 to move away from the support frames 200, thus completing the disassembly of the finished chemical fiber bags 300.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the outer frame 100 is made of aluminum alloy. Aluminum alloy has the characteristics of being lightweight and high-strength. More importantly, it can significantly improve the corrosion resistance of the outer frame 100. When aluminum alloy comes into contact with air, a dense aluminum oxide film will quickly form on the surface. This oxide film has a strong passivation effect and can effectively prevent the aluminum alloy substrate from directly contacting corrosive media, thereby greatly improving its resistance to oxidation, moisture, acid and alkali corrosion. Even under harsh environmental conditions, such as high humidity and acid and alkali corrosion, the aluminum alloy outer frame 100 can maintain long-term stability and service life, reduce the frequency of maintenance and replacement, and reduce overall operating costs.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the splicing joints of the outer frame 100 are fixed with aluminum alloy corner brackets. The aluminum alloy corner brackets themselves have high strength and rigidity, which can effectively disperse and transfer the stress on the outer frame 100, avoiding deformation or damage caused by stress concentration. The corner brackets are usually fixed by bolts or rivets. Compared with direct welding or other connection methods, this connection method has higher reliability and maintainability. In addition, corner bracket fixing can also significantly improve installation accuracy and ensure overall sealing.

[0031] like Figure 1 and Figure 2 As shown, the finished chemical fiber bag 300 is composed of multiple layers of fiber materials. Different layers of fiber materials have different pore sizes and densities, forming a step-by-step filtration effect. Larger particles are first intercepted by the outer layer of fibers, while smaller particles are further captured by the inner layer of fibers, preventing the filter bag from clogging too quickly, extending its service life. In addition, the multi-layer structure increases the surface area of ​​the filter bag, thereby improving the dust holding capacity, and can also effectively remove tiny particulate matter with a diameter greater than 0.5 micrometers in the air.

[0032] like Figure 2 As shown, the diameter of the end of the finished chemical fiber bag 300 near the support frame 200 is larger than the diameter of the end away from the support frame 200. The conical structure allows the flow cross-sectional area to gradually increase after air enters the finished chemical fiber bag 300, and the airflow speed to slow down. It can also better fit with the support frame 200 to form a tight seal, and can also improve the overall stability of the finished chemical fiber bag 300.

[0033] Example 2

[0034] like Figures 4-5As shown, the difference from Embodiment 1 is that the support frame 200 is provided with a fixing component for fixing the finished chemical fiber bag 300. The fixing component includes a plurality of first hook and loop fasteners 501, which are all located in the upper middle part of the support frame 200. Each of the finished chemical fiber bags 300 has a support strip 502 at its top. Each of the support strips 502 has a second hook and loop fastener 503 at one end near the first hook and loop fastener 501. Both the first hook and loop fasteners 501 and the second hook and loop fastener 503 are made of polyester fiber material. By pulling the support strip 502, the second hook and loop fastener 503 are moved. Then the support strip 502 is placed on the support frame 200, and then the second hook and loop fastener 503 and the first hook and loop fastener 501 are attached to fix the finished chemical fiber bag 300.

[0035] The above embodiment discloses a medium-efficiency bag filter, in which the finished chemical fiber bag 300 is fixed by placing the hook 400 on the support frame 200. Then, the finished chemical fiber bag 300 can filter particulate matter. The finished chemical fiber bag 300 can also optimize airflow, reduce resistance, improve sealing, and reduce air leakage, thereby effectively removing tiny particulate matter with a diameter greater than 0.5 micrometers. When it is necessary to disassemble the finished chemical fiber bag 300, the hook 400 can be moved away from the support frame 200 to disassemble the finished chemical fiber bag 300, thereby avoiding the continuous accumulation of pollutants such as dust, particulate matter, and oil mist on the surface of the finished chemical fiber bag 300.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
