Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal equipment, in particular to a filter element structure for an industrial dust collector. Background Technique

[0002] The equipment that separates industrial dust from flue gas is called an industrial dust collector or industrial dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price of the dust collector, the operation and maintenance costs, the length of service life, and the ease of operation and management are also important factors to consider its performance. The industrial dust removal filter element is an important component in the industrial dust collector, which can filter out the dust in the compressed air and has the characteristics of high dust filtration efficiency, simple installation, convenient use and maintenance.

[0003] As disclosed in the authorized announcement number CN219308233U, a filter element structure for an industrial dust collector is disclosed, including a filter element. A fixing piece is fixedly installed at the upper end of the filter element, a supporting plate is fixedly connected to the lower end of the filter element, and a protection mechanism is movably arranged on the fixing piece and located on the outer surface of the filter element. The device is placed inside the industrial dust collector. The insertion block arranged on the lower surface of the supporting plate is inserted and matched with the internal components of the industrial dust collector, and the device is fixed inside the industrial dust collector through the bolt holes. The annular protection shell movably arranged on the outer surface of the filter element, when the worker replaces the old filter element later, inserts it on the outer surface of the filter element, so that the worker is not easy to touch the dust on the outer surface of the old filter element. At the same time, when carrying the filter element, the bumping and pulling phenomena of the non-woven fabric in the filter element can be effectively reduced, improving the safety of using the filter element. At the same time, the convex blocks arranged on the outer surface of the annular protection shell facilitate the worker to grasp and carry it.

[0004] However, for the existing filter element, when it is blocked after long-term use, since the filter element is an integral structure, the whole filter element needs to be replaced to ensure the filtration efficiency. However, this method increases the use cost. At the same time, the traditional filter element is not provided with protection and support, and the gas flow causes the filter bag to be bent and overlapped after long-term use, resulting in poor filtration effect. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a filter element structure for an industrial dust collector to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A filter element structure for an industrial dust collector, including a filtering mechanism and a housing mechanism. The housing mechanism is located outside the filtering mechanism. The filtering mechanism includes a corrugated bag. A lower cover is fixedly installed at the bottom end of the corrugated bag, a support corrugation frame is fixedly installed in the middle of the corrugated bag, and a support frame is fixedly installed inside the corrugated bag.

[0008] Preferably, the filtering mechanism further includes an upper cover which is fixedly installed at the top end of the corrugated bag. An installation cylinder is fixedly installed at the top end of the upper cover, and an installation screw thread is fixedly installed at the top end of the installation cylinder.

[0009] Preferably, the housing mechanism includes a lower end cover. A protective frame is fixedly installed at the top end of the lower end cover, a protective net is fixedly installed inside the protective frame, and a corrugated bag is movably installed inside the protective net.

[0010] Preferably, a first connecting cylinder is fixedly installed at the top end of the protective frame. An internal screw thread is provided inside the first connecting cylinder, and an external screw thread is movably installed on the internal screw thread.

[0011] Preferably, the external screw thread is fixedly installed on the outside of a second connecting cylinder. An upper end cover is fixedly installed at the top end of the second connecting cylinder, and a sealing gasket is movably installed at the connection between the upper end cover and the first connecting cylinder.

[0012] Preferably, a sealing backing plate is movably installed at the top end of the upper end cover. A groove is provided at the top end of the upper end cover, and an installation cylinder is movably installed inside the groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] For the filter element structure for an industrial dust collector, when the filter element becomes blocked, the user removes the filter element and takes out the internal corrugated bag by screwing the upper end cover, so that the filter element can be conveniently cleaned. After cleaning, the filter element can be reused, reducing the replacement cost during use.

[0015] For the filter element structure for an industrial dust collector, the support corrugated frame can prevent the corrugations on the corrugated bag from merging due to gas flow, thereby avoiding the situation where gas cannot flow on the merged corrugations during filtration, resulting in dust not being filtered. At the same time, the support frame can support the entire inside of the corrugated bag, preventing the corrugated bag from being bent by gas flow, which may cause non-filtration.

Detailed implementation

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 4 As shown, a technical solution provided by the present invention:

[0023] A filter element structure for an industrial dust collector includes a filtering mechanism 101 and a housing mechanism 102. The housing mechanism 102 is located outside the filtering mechanism 101. The filtering mechanism 101 includes a corrugated bag 103. A lower cover 104 is fixedly installed at the bottom end of the corrugated bag 103. A corrugation support 105 is fixedly installed in the middle of the corrugated bag 103. A support frame 106 is fixedly installed inside the corrugated bag 103.

[0024] Through the above solution, small particle dust can be filtered through the corrugated bag. The corrugation support can prevent the corrugations on the corrugated bag from merging due to gas flow, thereby avoiding the situation where gas cannot flow on the merged corrugations during filtration, resulting in dust not being filtered. The support frame can support the whole inside of the corrugated bag to prevent the corrugated bag from being bent by gas flow, resulting in unfiltered situations.

[0025] In this embodiment, preferably, the filtering mechanism 101 further includes an upper cover 201. The upper cover 201 is fixedly installed at the top end of the corrugated bag 103. An installation cylinder 202 is fixedly installed at the top end of the upper cover 201. An installation thread 203 is fixedly installed at the top end of the installation cylinder 202.

[0026] Through the above solution, the top of the corrugated bag can be sealed by the upper cover. Gas can flow through the installation cylinder. The whole filter element can be connected to the industrial dust collector through the installation thread.

[0027] In this embodiment, preferably, the housing mechanism 102 includes a lower end cover 204. A protective frame 205 is fixedly installed at the top end of the lower end cover 204. A protective net 206 is fixedly installed inside the protective frame 205. A corrugated bag 103 is movably installed inside the protective net 206.

[0028] Through the above solution, the protective frame can be supported and fixed by the lower end cover. The protective net can be installed by the protective frame. The large particulate dust in the air can be filtered by the protective net, and at the same time, the internal corrugated bag can be protected.

[0029] In this embodiment, preferably, a first connecting cylinder 301 is fixedly installed at the top end of the protective frame 205. Internal threads 302 are provided inside the first connecting cylinder 301. External threads 303 are movably installed on the internal threads 302.

[0030] Through the above solution, the first connecting cylinder and the second connecting cylinder can be installed by means of the internal and external threads.

[0031] In this embodiment, preferably, the external threads 303 are fixedly installed on the outside of a second connecting cylinder 304. An upper end cover 305 is fixedly installed at the top end of the second connecting cylinder 304. A sealing gasket 306 is movably installed at the connection between the upper end cover 305 and the first connecting cylinder 301.

[0032] Through the above solution, the upper end cover is driven by the second connecting cylinder to be installed, so that the corrugated bag can be clamped inside the protective frame. The sealing gasket can keep the connection between the upper end cover and the first connecting cylinder sealed.

[0033] In this embodiment, preferably, a sealing backing plate 401 is movably installed at the top end of the upper end cover 305. A groove 402 is provided at the top end of the upper end cover 305. An installation cylinder 202 is movably installed inside the groove 402.

[0034] Through the above solution, the installation cylinder can penetrate through the groove. When the filter element is installed on the dust collector through the installation threads on the installation cylinder, the sealing backing plate can keep the installation position sealed.

[0035] When the filter element structure for an industrial dust collector in this embodiment is in use, the user installs the corrugated bag 103 into the interior of the protective net 206 through the first connecting cylinder 301, then installs the sealing gasket 306 at the top of the first connecting cylinder 301, and screws it tightly through the internal thread 302 and the external thread 303, so that the second connecting cylinder 304 and the first connecting cylinder 301 are connected and the upper end cover 305 and the second connecting cylinder 304 clamp the sealing gasket 306. At this time, the installation cylinder 202 penetrates the groove 402. The user sleeves the sealing backing plate 401 on the outside of the installation cylinder 202, and then connects it to the industrial dust collector through the installation thread 203 at the top of the installation cylinder 202, so that the industrial dust collector and the upper end cover 305 clamp the sealing backing plate 401, thereby completing the installation of the entire filter element and keeping the connection sealed. When dust removal is carried out, the industrial dust collector works to drive the air flow to suck the dust in the air into the dust collector. Since the air flows through the protective net 206 and the corrugated bag 103, the large-particle dust in the dust is filtered by the protective net 206, and the unfiltered small-particle dust is filtered by the corrugated bag 103, so that the dust in the air flowing through the protective net 206 and the corrugated bag 103 is removed. When the filter element is filtering, the support corrugation frame 105 can prevent the corrugations on the corrugated bag 103 from merging due to gas flow, thereby avoiding the situation where gas cannot flow on the merged corrugated bags 103 during filtration, resulting in dust not being filtered. At the same time, the support frame 106 inside the corrugated bag 103 can support the whole inside of the corrugated bag 103, avoiding the situation where the corrugated bag 103 is bent by the gas flow, resulting in non-filtration. And when the filter screen is blocked, the user can remove the internal corrugated bag 103 by screwing the upper end cover 305, so that the filter element is convenient to clean.
