[0001] The utility model relates to the technical field of dust removal filter barrels, and particularly relates to a quick-connect ultra-fine fiber filter barrel. Background Art

[0002] In the field of dust removal technology, filter barrels are common filtering devices. As the core component of filtration, the filter element directly affects the filtration efficiency and effect. At present, in the dust removal filter cartridge, filter elements such as polyester fiber, polyester fiber, and wood pulp paper are selected for filtration, resulting in problems such as high resistance of the filter barrel, increased energy consumption, and limited filtration efficiency. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model discloses a quick-connect ultra-fine fiber filter barrel.

[0004] The specific technical solutions are as follows:

[0005] A quick-connect ultra-fine fiber filter barrel is used for terminal filtration of a dust removal system to block dust particles and bacterial concentration in the control room of the dust removal system; the filter barrel includes an upper end cover, a lower end cover, an outer protection net, an inner protection net, a filter element, and a quick-connect component; both the upper end cover and the lower end cover are annular, and both the outer protection net and the inner protection net are cylindrical, jointly supporting and enclosing a cylindrical columnar filtering medium space, with the outer side being the air inlet surface and the inner side being the air outlet surface; the filter element is embedded in the filtering space, and the filter element adopts ultra-fine fiber fiberglass filter paper; the quick-connect component includes a quick-connect interface and a sealing rubber ring, which are arranged at the outer end of the upper end cover, and the quick-connect interface is connected to the part to be filtered.

[0006] The ultra-fine fiber fiberglass filter paper is repeatedly folded back and forth, and the crease is shaped with a single-sided hot melt adhesive line. It is wound around the inner protection net in the reverse direction, and the joint is firmly bonded by hot melt adhesive without gaps. It is sleeved into the outer protection net and embedded into the upper end cover and the lower end cover together, and the special glue for the filter barrel end cover is poured for sealing.

[0007] The upper end cover and the lower end cover are sealed with sealing glue.

[0008] Both the outer protection net and the inner protection net are metal nets.

[0009] A disassembly and assembly handle is arranged at the outer end of the lower end cover to assist in opening and closing the filter barrel.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model provides an efficient ultra-fine fiber filter barrel, which is suitable for blocking dust particles in the control room of the dust removal system, controlling the air in the workshop, workstations, and external exhaust to meet the cleanliness standard, and is widely used for terminal filtration of the dust removal system. Low-resistance filtration can effectively reduce energy consumption and save energy.

[0012] This utility model uses ultra-fine fiber fiberglass filter paper to replace traditional filter paper. Compared with traditional filter elements such as polyester fiber, polyester fiber, and wood pulp paper, ultra-fine fiber fiberglass filter paper has the advantages of low resistance, high efficiency, acid and alkali resistance, etc. When the outer diameter size of the filter cartridge is certain, it can increase the filtration area, reduce the resistance, and achieve ultra-high efficiency under special working conditions, meeting the clean standard of the exhaust air.

[0013] The ultra-fine fiber fiberglass filter paper of this utility model is very thin. After being repeatedly folded back and forth, a hot melt adhesive line is applied on one side for shaping at the indentation, and it is wound around the inner protection net in the reverse direction, making the whole filter element form a tensile force, increasing the overall stiffness of the filter element. With the support of the metal outer protection net on the air inlet side and the metal inner protection net on the air outlet side, it increases the strength of the ultra-fine fiber fiberglass filter paper and isolates some large-particle dust. At the same time, it also increases the filtration area, thereby reducing the resistance and improving the filtration efficiency. The efficiency can reach U17, increasing the selection range of filtration accuracy to the greatest extent compared with filter elements such as polyester fiber, polyester fiber, and wood pulp paper.
