Description

Technical Field

[0001] This utility model relates to the field of dust collection bag technology, specifically a filter dust collection bag for glass powder production. Background Technology

[0002] Glass powder is an inorganic, amorphous, hard, ultrafine particle powder, appearing as a white powder. Its production uses high-temperature, high-purity silicon dioxide and alumina as raw materials, followed by an ultra-clean production process to form a disordered, transparent glass powder. It possesses stable chemical properties and exhibits resistance to acids and alkalis, chemical inertness, and a low coefficient of expansion, making it an ultra-weather-resistant powder material.

[0003] During the production of glass powder, there is loose dust in the production workshop. Therefore, corresponding bag dust collectors are set up to filter the dust in the air in the glass powder production workshop. The working mechanism of bag dust collectors is that dust-laden flue gas passes through the filter material and the dust particles are filtered down. The filter material captures coarse dust mainly through inertial collision, and captures fine dust mainly through diffusion and sieving.

[0004] Dust collector bags are a key component in the operation of baghouse dust collectors. Typically, cylindrical filter bags are vertically suspended inside the dust collector. During operation, the dust collector bags expand and contract due to repeated switching between filtration and backflushing. This process causes relative movement and friction between the dust collector bags and the filter cage, leading to localized wear and failure of the dust collector bags. This is detrimental to the stable dust removal of air in glass powder production workshops. Based on this, a filter dust collector bag for glass powder production is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a filter dust removal bag for glass powder production in order to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filter dust removal bag for glass powder production, comprising a dust removal bag, wherein an inner support arc-shaped rubber strip is provided on the inner side of the dust removal bag, the inner support arc-shaped rubber strip is used to form support between the dust removal bag and the dust removal frame, and to prevent friction between the dust removal bag and the dust removal frame.

[0007] The inner support arc-shaped rubber strips are arranged in multiple sets along the vertical direction, and each set of the inner support arc-shaped rubber strips includes two inner support arc-shaped rubber strips. The two inner support arc-shaped rubber strips in each set are symmetrically distributed and fixed to the inside of the dust collector bag along the circumferential direction, and the multiple sets of the inner support arc-shaped rubber strips in the vertical direction are distributed sequentially along the circumferential direction.

[0008] As a further improvement of this utility model: the top view cross-section of the multiple sets of inner support arc-shaped rubber strips is circular, and the inner diameter of the distribution trajectory of the multiple inner support arc-shaped rubber strips matches the outer diameter of the dust collector frame.

[0009] As a further embodiment of this utility model: there is a gap between the upper and lower ends of two vertically adjacent inner support arc-shaped rubber strips, and the inner support arc-shaped rubber strips are evenly provided with multiple folding notches along the vertical direction, and the inner support arc-shaped rubber strips can be folded through the folding notches.

[0010] As a further embodiment of this utility model: the inner surface of the inner support arc-shaped rubber strip is formed with multiple anti-slip grooves along the circumferential direction, the arc width of a single inner support arc-shaped rubber strip is greater than the distribution distance between the two vertical steel wires of the dust collector frame, and the inner diameter of the anti-slip groove matches the outer diameter of the vertical steel wire of the dust collector frame.

[0011] As a further improvement of this utility model: the inner support arc-shaped rubber strip and the anti-slip groove are integrally formed by rubber injection molding process, and the inner support arc-shaped rubber strip and the dust collector bag are fixedly bonded together by high temperature resistant adhesive.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting an internal support arc-shaped rubber strip, the dust collector frame contacts the internal support arc-shaped rubber strip, while other parts of the dust collector bag without the internal support arc-shaped rubber strip are at a certain distance from the dust collector frame. In this way, while the dust collector bag is opened, the parts of the dust collector bag without the internal support arc-shaped rubber strip have room for expansion and contraction. Moreover, the expanded and contracted parts of the dust collector bag will not come into contact with the dust collector frame and rub against it, and the friction between the internal support arc-shaped rubber strip and the dust collector frame will not affect the dust collector bag, thereby effectively improving the service life of the dust collector bag.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 In this embodiment of the present invention, a filter dust removal bag for glass powder production includes a dust removal bag 1. An inner support arc-shaped rubber strip 2 is provided on the inner side of the dust removal bag 1. The inner support arc-shaped rubber strip 2 is used to form a support between the dust removal bag 1 and the dust removal frame, so as to avoid friction between the dust removal bag 1 and the dust removal frame.

[0020] Multiple sets of inner support arc-shaped rubber strips 2 are arranged vertically, and each set of inner support arc-shaped rubber strips 2 includes two inner support arc-shaped rubber strips 2. The two inner support arc-shaped rubber strips 2 in each set are symmetrically distributed and fixed to the inside of the dust collector bag 1 along the circumferential direction, and the multiple sets of inner support arc-shaped rubber strips 2 in the vertical direction are distributed sequentially along the circumferential direction.

[0021] The top view of the multiple sets of internal support arc-shaped rubber strips 2 is circular, and the inner diameter of the distribution trajectory of the multiple internal support arc-shaped rubber strips 2 matches the outer diameter of the dust collector frame.

[0022] In this embodiment: When the dust collector bag 1 is installed and used, when its dust collector frame is inserted into the dust collector bag 1 to support it, the dust collector frame contacts the inner support arc-shaped rubber strip 2, while other parts of the dust collector bag 1 without the inner support arc-shaped rubber strip 2 are at a certain distance from the dust collector frame. In this way, while the dust collector bag 1 is opened, the parts of the dust collector bag 1 without the inner support arc-shaped rubber strip 2 have space for expansion and contraction.

[0023] Meanwhile, during the switching between filtration and backflushing states, the expansion and contraction parts of the dust collector bag 1 will not come into contact with or rub against the dust collector frame, and the friction between the inner support arc-shaped rubber strip 2 and the dust collector frame will not affect the dust collector bag 1, thereby effectively improving the service life of the dust collector bag 1.

[0024] It should also be noted that: the ring structure composed of multiple sets of internal support arc-shaped rubber strips 2 provides support for the dust collector bag 1 along the circumference, thus preventing the dust collector bag 1 from undergoing excessive deformation and shrinkage during filtration.

[0025] Please refer to this carefully. Figures 1-2 There is a gap between the upper and lower ends of two vertically adjacent inner support arc-shaped rubber strips 2. The inner support arc-shaped rubber strips 2 are evenly provided with multiple folding notches 4 in the vertical direction. The inner support arc-shaped rubber strips 2 can be folded through the folding notches 4.

[0026] In this embodiment: the structure layout with gaps at the upper and lower ends of the inner support arc-shaped rubber strip 2 allows the dust collector bag 1 to be bent through this part during storage and transportation. At the same time, the inner support arc-shaped rubber strip 2 can also be folded through the folding notch 4, so that the dust collector bag 1 can be folded and stored better.

[0027] Please refer to this carefully. Figures 1 to 3 The inner surface of the inner support arc-shaped rubber strip 2 is formed with multiple anti-slip grooves 3 along the annular direction. The arc width of a single inner support arc-shaped rubber strip 2 is greater than the distribution distance between the two vertical steel wires of the dust collector frame. The inner diameter of the anti-slip groove 3 matches the outer diameter of the vertical steel wire of the dust collector frame.

[0028] In this embodiment, it should be noted that the distribution spacing of the anti-slip grooves 3 matches the distribution spacing of the vertical steel wires of the dust removal keel.

[0029] When the dust collector keel is inserted into the dust collector bag 1, the dust collector keel can be rotated and adjusted so that the vertical steel wire on the dust collector keel is inserted into the anti-slip groove 3. This can achieve relative positioning between the inner support arc-shaped rubber strip 2 and the circumferential direction of the dust collector keel, making the use of the dust collector bag 1 more stable.

[0030] Please refer to this carefully. Figures 1 to 3 The inner support arc-shaped rubber strip 2 and the anti-slip groove 3 are integrally formed by rubber injection molding process. The inner support arc-shaped rubber strip 2 and the dust collector bag 1 are fixedly bonded by high temperature resistant adhesive.

[0031] In this embodiment, the overall production and processing technology of the inner support arc-shaped rubber strip 2 is simple, and the inner support arc-shaped rubber strip 2 can be formed on the basis of the existing dust collector bag 1, which facilitates the promotion and production.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
