Technical Field

[0001] The utility model belongs to the technical field of filter cartridge type dust collectors, in particular to a filter cartridge which is beneficial to pulse back-blowing and cleaning. Background Art

[0002] A Chinese patent document with Chinese patent application number CN202321885047.1 discloses a technical solution entitled "A filter cartridge back-blowing device". In this technical solution, the gas is back-blown into the filter cartridge by setting a back-blowing device so that the dust on the outer surface of the filter cartridge can be removed. However, the filter cartridge in this technical solution is a traditional internal straight-through structure with a relatively low cleaning efficiency, which is not conducive to the long-term operation of the equipment and affects the service life of the filter. Utility Model Content

[0003] The utility model aims to solve the above problems and shortcomings and provide a filter cartridge that is conducive to pulse backblowing cleaning. The filter cartridge can increase the flow rate of the pulse gas inside the filter cartridge during backblowing, thereby improving the cleaning efficiency and extending the service life of the filter cartridge.

[0004] The technical solution of the utility model is achieved in this way:

[0005] A pulse back-blowing clean filter cartridge comprises an upper cover, a cartridge body and a lower cover, wherein the upper cover is provided with an upper cover plate through hole, the lower cover is composed of a bottom cover plate and a diverter column, the upper cover is mounted at one end of the cartridge body, and the lower cover is mounted at the other end of the cartridge body.

[0006] By adopting the above-mentioned scheme, the pulse gas can enter the interior of the cylinder through the through hole of the upper cover plate. When the pulse gas goes straight to the lower cover along the through hole of the upper cover plate, the pulse gas in only one direction will be evenly guided to the inner wall of the cylinder under the action of the diverter column, and the flow rate of the pulse gas will be increased at the same time, so that the dust attached to the outside of the cylinder can be blown away more fully.

[0007] Preferably, the upper cover comprises an upper cover plate and a flow guide pipe, and the flow guide pipe is communicated with a through hole of the upper cover plate.

[0008] By adopting the above solution, the upper cover plate and the guide tube form a boss, and the guide tube can align the pulse gas entering the cylinder body with the lower cover, and at the same time can facilitate the installation of the upper cover and the cylinder body.

[0009] Preferably, the diverter column is in a cone shape.

[0010] By adopting the above solution, the cone can disperse the pulse gas entering the interior of the cylinder more evenly onto the inner wall of the cylinder.

[0011] Preferably, the bottom cover plate is circular, and a limiting flange is arranged on the outer side of the bottom cover plate.

[0012] Preferably, the filter material is a hollow cylinder, and the flow guide tube is placed in the inner cavity at one end of the cylinder body and the two are in close contact.

[0013] Preferably, the limiting flange and the root of the diverter column form a clamping area, and one end of the cylinder body and the lower cover are clamped in the clamping area.

[0014] By adopting the above solution, the lower cover and the cylinder body can be more closely fitted, and at the same time, it can prevent the high-speed pulse gas from impacting the cylinder body composed of filter materials and causing deformation during the pulse backblowing operation.

[0015] In summary, the beneficial effects of the utility model are as follows: the filter cartridge upper cover is provided with a guide tube, the lower cover is provided with a diverter column, and the lower cover is provided with a clamping area, so that when the pulse gas enters the interior of the cylinder body, the pulse gas has a consistent direction and a consistent flow rate, and the pulse gas is directly blown to the diverter column under the guidance of the guide tube, and then under the action of the diverter column, the pulse gas is evenly dispersed to the inner wall of the cylinder body while increasing the gas flow rate, so that the dust remaining on the outside of the cylinder body can be better back-blown, the dust cleaning efficiency is improved, the dust remaining on the outside of the cylinder body is reduced, and the service life of the filter cartridge is extended. Therefore, the filter cartridge has the advantages of good dust cleaning effect, high efficiency, and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the content of the utility model more clearly understood, the utility model is further described below based on specific embodiments in combination with the accompanying drawings.

[0024] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0025] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0026] Understandably, in the related art, the principle of backwashing is to use external high-pressure gas to instantly rush into the interior of the filter cartridge, making the internal pressure of the filter cartridge much greater than the external pressure, so that the gas is ejected from the inside to the outside to blow away the dust attached to the outer wall of the filter cartridge and achieve the effect of cleaning. However, because the interior of the filter cartridge is a straight-through structure, the internal gas flow direction is inconsistent and the flow rate is uneven, resulting in poor cleaning effect and low efficiency.

[0027] In view of this, if Figures 1 to 5 As shown, the utility model is a kind of pulse back-blowing clean filter cartridge, including an upper cover 1, a cylinder body 2 and a lower cover 3, wherein the upper cover 1 is provided with an upper cover plate through hole 103, and the lower cover 3 is composed of a bottom cover plate 301 and a diverter column 302, the upper cover is installed at one end of the cylinder body 2, and the lower cover is installed at the other end of the cylinder body 2.

[0028] In the above scheme, the barrel 2 can be a material with filtering function, which is composed of polyester fiber, needle felt, woven fabric, linen, spunlace felt, stainless steel mesh and other materials. When it is necessary to clean the dust attached to the outside of the barrel 2, the external pulse gas enters the barrel 2 through the upper cover plate through hole 103. When the pulse gas passes through the upper cover plate through hole 103 to the bottom, under the action of the diverter column 302, the pulse gas will be uniformly guided to flow to the inner wall of the barrel 2. At the same time, the flow rate of the pulse gas is increased under the action of the diverter column, so that the dust attached to the outside of the barrel 2 can be blown away more fully, thereby improving the cleaning efficiency.

[0029] In one embodiment, the upper cover 1 includes an upper cover plate 101 and a flow guide pipe 102 , and the flow guide pipe 102 is connected to a through hole 103 of the upper cover plate.

[0030] In the above scheme, the upper cover 101 and the guide tube 102 form a T-shaped boss. The guide tube 102 can guide the pulse gas with inconsistent directions to the direction of the top of the diversion column 302 when entering the cylinder body, and can also facilitate the installation of the upper cover 1 and the cylinder body 2.

[0031] In one embodiment, the splitter column 302 is in a cone shape.

[0032] In the above scheme, if Figure 2 , Figure 5 As shown, when the pulse gas flows toward the diverter column 302, the pulse gas is deflected on the surface direction of the conical diverter column 302, and is evenly guided to flow toward the inner wall of the cylinder body 2. At this time, the flow velocity of the pulse gas on the surface of the diverter column 302 is greater, which can fully impact the dust attached to the outer side of the cylinder body 2, thereby achieving the cleaning effect better and more fully.

[0033] In one embodiment, the bottom cover plate 301 is circular, and a limiting flange 303 is disposed on the outer side of the bottom cover plate 301 .

[0034] In one embodiment, the barrel body 2 is a hollow cylinder, and the flow guide tube 102 is placed in the inner cavity of one end of the barrel body 2 and the two are in close contact.

[0035] In one embodiment, the limiting flange 303 and the root of the diverter column 302 form a clamping area, and the barrel body 2 and the lower cover 3 are clamped in the clamping area.

[0036] By adopting the above-mentioned scheme, the filter cartridge composed of multiple cylindrical barrels 2 can have a larger working area in a limited space. According to the shape of the barrel 2, the shape of the upper cover 1 and the lower cover 2 are matched. The guide tube 102 and the upper cover plate 101 can be well connected with one end of the barrel 2, and the other end of the barrel 2 and the lower cover plate 3 are clamped in the clamping area, so that the barrel 2 can form a relatively closed space. Whether the barrel 2 absorbs dust in the vacuum state or the dust attached to the outside of the barrel 2 needs to be cleaned, it can have a good sealing effect.

[0037] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
