[0025] The following will be further described in detail with reference to the attached Figure 1-6 to the present application.
[0026] The embodiment of the present application discloses a new type of oil mesh filter. Refer to Figure 1 , Figure 2 and Figure 3 , the new type of oil mesh filter includes a filter body 1. The filter will be made of high-strength stainless steel material and coated with anti-corrosion paint. Compared with the same model of oil mesh filter, the weight is reduced by more than 50%, the cost is reduced by more than 20%, and it has functional performance characteristics such as light weight, rust prevention, long service life, and free / easy maintenance, and has higher performance advantages. The filter body 1 includes a shell and a filter component 15 arranged inside the shell. The filter component 15 is used for filtering air. Connector short pipes 2 are arranged on both sides of the shell. The connector short pipes 2 are formed by rolling and spinning stainless steel materials. A first connection groove 3 is concavely formed on the peripheral wall of the connector short pipe 2; a connector 4 is convexly formed on the peripheral wall of the pipeline and near the pipeline port. It also includes a sealing ring 5 and a hoop ring 6. The sealing ring 5 is sleeved into the connection groove and the connector 4 and is clamped between the connector short pipe 2 and the connector 4. The hoop ring 6 is used to fix the sealing ring 5 between the connector short pipe 2 and the connector 4.
[0027] When the dust filter is connected to the civil air defense ventilation duct, move the housing to the interface of the duct, and make the connecting short pipe 2 abut against the end face of the duct. Then, insert the sealing ring 5 between the connecting short pipe 2 and the duct. Subsequently, use the hoop 6 to lock the sealing ring 5 between the connecting short pipe 2 and the duct. During the above installation process, the use of flanges is reduced, the installation cost of the dust filter is lowered, and it is convenient to connect the dust filter into the duct.
[0028] Referring to the figures, to facilitate the installation of the dust filtering assembly 15 into the housing, in the embodiment of the present application, the housing includes a front housing 11, a rear housing 12, an installation skeleton 14, and a partition 13. Both the front housing 11 and the rear housing 12 are conical. The connecting short pipe 2 is located at the smaller diameter end of the front housing 11 and the rear housing 12. The larger diameter ends of the front housing 11 and the rear housing 12 abut against each other and are fixedly connected (welded into a whole to ensure peripheral sealing). The installation skeleton 14 is located inside the housing and is used to install the dust filtering assembly 15. Both the front housing 11 and the rear housing 12 are provided with installation openings 7. The dust filtering assembly 15 is installed onto the dust filtering assembly 15 through the installation openings 7. The partition 13 is buckled on the installation openings 7. The front housing 11 and the rear housing 12 are fixedly connected by processes such as seamless welding. When installing or replacing the dust filtering assembly 15, remove the partition 13 from the housing, and then slide the dust filtering assembly 15 out from the installation opening 7, thereby facilitating the installation or replacement of the dust filtering assembly 15.
[0029] Referring to the figure, the partition 13 includes a cover plate 131 and a rubber sealing plate 132 provided on the cover plate 131. The cover plate 131 and the rubber sealing plate 132 are fixed to each other by bolts and nuts. The dust filtering assembly 15 is fixedly installed on the cover plate 131 by bolts; under the action of the rubber sealing plate 132, the sealing performance between the cover plate 131 and the housing is improved, the possibility of gas leakage from the installation opening 7 is reduced, and thus the gas filtering effect is improved.
[0030] Referring to the figure, in the embodiment of the present application, the partition 13 further includes a positioning plate 133. The positioning plate 133 is bent into a door shape. The top plate of the positioning plate 133 fits on the rubber sealing plate 132, and the vertical plate of the positioning plate 133 abuts against the side of the housing. The cover plate 131, the rubber sealing plate 132, and the positioning plate 133 are all fixed to each other by bolts and nuts; under the action of the positioning plate 133, the cover plate 131, etc. are clamped on the housing, thereby reducing the possibility of the partition 13 falling off the housing.
[0031] Referring to the figures, in the embodiment of the present application, the mounting frame 14 includes a first receiving plate 141 and a second receiving plate 142. The first receiving plate 141 and the second receiving plate 142 are respectively fixedly arranged inside the front housing 11 and the rear housing 12. The top surface of the second receiving plate 142 is bent towards the first receiving plate 141 in an L shape. The dust filtering assembly 15 includes an oil mesh module. The oil mesh module is received on the first receiving plate 141 and is snap - connected to the second receiving plate 142. The oil mesh module includes multiple layers of stainless steel meshes with dense holes. The multiple layers of stainless steel meshes with dense holes are laid and arranged, and oil is impregnated on the meshes. After the multiple layers of stainless steel meshes with dense holes are stacked, they are moved onto the first receiving plate 141, and the multiple layers of stainless steel meshes with dense holes are gradually pushed so that the multiple layers of stainless steel meshes with dense holes are snap - connected to the second receiving plate 142, thus completing the installation of the multiple layers of stainless steel meshes with dense holes.
[0032] In the embodiment of the present application, for the convenience of installing the oil mesh module, both the first receiving plate 141 and the second receiving plate 142 are in a gate shape and the opening is connected to the installation opening 7. A partition plate 8 is arranged between the first receiving plate 141 and the second receiving plate 142. The partition plate 8 is used to partition the mounting frame 14 to form two installation chambers 9.
[0033] Referring to the figures, to improve the stability of the oil mesh module inside the housing and the stability of the housing, first cross - shaped supports 10 are fixedly arranged on the outer sides of both the first receiving plate 141 and the second receiving plate 142, and the ends of the first cross - shaped supports 10 are fixedly arranged on the inner side of the housing. The first cross - shaped supports 10 are used to reinforce the inner rings of the first receiving plate 141 and the second receiving plate 142. Further, second cross - shaped supports 16 are fixedly arranged on the outer sides of the first cross - shaped supports 10 and are parallel to the first cross - shaped supports 10.
[0034] Referring to the figures, to improve the stability of the housing, support angle steels 17 are arranged inside both the front housing 11 and the rear housing 12. The support angle steels 17 are used to support the inside of the front housing 11 and the inner housing.
[0035] The implementation principle of a new type of oil - mesh dust filter in the embodiment of the present application is as follows:
[0036] When the dust filter is connected to the civil air defense ventilation duct, the housing is moved to the interface of the duct, and the joint short pipe 2 is abutted against the end face of the duct. Subsequently, the sealing ring 5 is connected between the joint short pipe 2 and the duct. Then, the sealing ring 5 is locked between the joint short pipe 2 and the duct using the hoop 6. During the above installation process, the use of flanges is reduced, the installation cost of the dust filter is lowered, and it is convenient to connect the dust filter into the duct.
[0037] The above are all the preferred embodiments of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
