Technical Field
[0001] The utility model relates to the technical field of metal filter bags, in particular to a combined structure of a metal pleated filter cartridge. Background Art
[0002] Metal filter bag dust removal is a bag dust removal technology that uses metal filter bags to replace textile filter bags. In recent years, it has gradually developed in the field of high-temperature industrial flue gas. High-temperature resistant metal filter bags are porous filter materials made of metal fibers or metal powders through pressing and sintering, and are welded into filter bag form. Metal filter bags have the characteristics of high temperature resistance, strong acid and alkali resistance, high mechanical strength, and certain flexibility. They are ideal high-temperature flue gas dust removal materials. At the same time, metal pleated filter bags are products that combine metal filter bags with pleated filter bags, which can greatly increase the filtration area and significantly reduce the filtration wind speed without changing the main structure of the dust collector.
[0003] When the filter bag is working, the dust-containing gas directly passes through the filter bag, so that the filter bag blocks the dust. When the filter bag removes dust-containing gas with high temperature and often accompanied by sparks and static electricity, it is easy to cause combustion accidents, which will affect the service life of the filter bag and is not conducive to improving the user experience of the staff. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a combined structure of a metal pleated filter cartridge.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a combined structure of a metal pleated filter cartridge, comprising a fixed frame, a filter bag main body for dust removal is arranged on the fixed frame, a sealing gasket is arranged on the inner bottom wall of the fixed frame, a conductive coil is arranged on the sealing gasket, a wire is connected to the conductive coil, the other end of the wire extends outside the fixed frame, a connecting block is fixed on the side wall of the wire, and a traceless rubber layer is arranged on the side wall of the connecting block.
[0006] By adopting the above technical solution, when the staff is removing dust from dust-containing gas accompanied by sparks and static electricity, a large amount of static electricity is easily attached to the surface of the filter bag body. At this time, the staff only needs to fix the connecting block to a suitable position through a traceless adhesive layer to guide the static electricity on the surface of the filter bag body to the wire coil and then to the outside world through the wire, thereby improving the anti-static ability of the filter bag body and reducing the probability of fire of the filter bag body.
[0007] Furthermore, the fixed frame includes a sealing cover, a plurality of vertical rods fixed to the inner bottom wall of the sealing cover, an annular rod installed on the plurality of vertical rods, and a connecting ring installed on the upper ends of the plurality of vertical rods.
[0008] Furthermore, the filter bag body includes a filter bag edge, a steel ring arranged inside the filter bag edge, a plastic ring arranged on the filter bag edge, and a filter bag interconnected with the filter bag edge.
[0009] By adopting the above technical solution, the filtration area of conventional filter bags is limited, the pressure difference between the air inlet and the air outlet of the dust collector is high, and the production capacity is restricted. Without the need to modify the dust collector, the filter bag body can be used with a matching fixed frame to increase the filtration area of the dust filter bag by 80% or more and reduce the pressure difference between the air inlet and the air outlet by 30%, thereby maintaining a good production state.
[0010] Furthermore, the steel ring is made of 316 stainless steel.
[0011] By adopting the above technical solution, 316 stainless steel has good corrosion resistance, which reduces the probability of rust on the steel ring and improves the user experience of the staff.
[0012] Furthermore, the plastic ring is made of polypropylene.
[0013] By adopting the above technical solution, polypropylene is a thermoplastic synthetic resin with excellent performance. It is a colorless, translucent, thermoplastic, lightweight general-purpose plastic with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high-wear processing performance. The plastic ring made of polypropylene has good mechanical properties, which prolongs the service life of the plastic ring and improves the use experience of the staff.
[0014] Furthermore, the filter bag is a filter bag woven from a mixture of polypropylene fiber, polyester fiber, nylon fiber and polytetrafluoroethylene.
[0015] By adopting the above technical scheme, polypropylene fiber has high wear resistance, polyester fiber has excellent wrinkle resistance and shape retention, nylon fiber has good elastic recovery rate, polytetrafluoroethylene has the characteristics of high temperature resistance and extremely low friction coefficient, so that the filter bag has good wear resistance, wrinkle resistance, shape retention, elastic recovery rate and high temperature resistance, which is beneficial to improve the service life of the filter bag.
[0016] Furthermore, the fixed frame is made of silicone.
[0017] By adopting the above technical solution, the fixed frame made of organic silicon is light to use, easy to install and maintain, firmly welded, and has a smooth and straight appearance. The fixed frame produces important performance and functions in actual use. The organic silicon fixed frame operates and works accurately according to certain forms and conditions, can adapt to market changes, fully demonstrate the advantages and characteristics of the organic silicon fixed frame, and work well in dust removal work according to market conditions.
[0018] Furthermore, an electrostatic powder coating is provided on the side wall of the steel ring.
[0019] By adopting the above technical solution, plastic spraying is a surface treatment method of spraying plastic powder on parts. Plastic spraying is what we often call electrostatic powder spraying. Its treatment process is a relatively common metal surface treatment decoration technology used internationally since the 1980s. Electrostatic powder coating can protect the steel ring and improve the beauty of the steel ring, thereby improving the user experience of the staff.
[0020] In summary, the utility model has the following beneficial effects:
[0021] 1. In this application, when the staff removes dust from dust-laden gas accompanied by sparks and static electricity, a large amount of static electricity is easily attached to the surface of the filter bag body. At this time, the staff only needs to fix the connecting block to a suitable position through a traceless adhesive layer, so that the static electricity on the surface of the filter bag body can be guided to the wire coil and then guided to the outside through the wire, thereby improving the anti-static ability of the filter bag body and reducing the probability of fire of the filter bag body;
[0022] 2. In this application, the filtration area of conventional filter bags is limited, the pressure difference between the air inlet and the air outlet of the dust collector is high, and the production capacity is restricted.

[0032] Conventional filter bags have limited filtration area, and the pressure difference between the air inlet and the air outlet of the dust collector is relatively high, which restricts production capacity. The filter bag body 2 and the matching fixed frame 1 can increase the filtration area of the dust filter bag by 80% or more and reduce the pressure difference between the air inlet and the air outlet by 30% without the need for dust collector modification, thereby maintaining a good production state.
