Description

Technical Field

[0001] The present invention relates to the field of dust removal filter bags, and more specifically, it relates to an anti-fracture type dust removal filter bag. Background Art

[0002] In industrial production, there are often a large number of scenarios for gas dust removal. Therefore, a dust removal machine is generally used to remove dust from the air. The dust removal filter bag is an important part of dust removal. The gas enters the inside of the dust removal filter bag from the outside of the dust removal filter bag, so as to block dust and the like in the gas through the dust removal filter bag, realizing the dust removal of the gas. The existing dust removal filter bags are generally supported by an internal frame, and there is a lack of a matching structure on the outside. After the filter bag removes dust, the pulse structure on the dust removal machine fills the gas into the filter bag to blow off the dust on the outer surface of the filter bag. When the inside of the filter bag is blown by air, deformation will occur. The long-term deformation of the filter bag will cause the filter bag to break, thus affecting the service life of the filter bag and making it inconvenient to use the filter bag. At the same time, the existing dust removal filter bag and the internal frame are of an integral structure. When the dust removal filter bag needs to be replaced, the internal frame also needs to be replaced together, resulting in waste of the frame and increasing the use cost of the air blower.

[0015] (III) Advantageous Effects

[0016] Compared with the prior art, the present invention provides an anti-fracture dust removal filter bag, which has the following advantageous effects:

[0017] 1. The present invention is provided with an auxiliary structure. When installing the filter bag, the opening edge of the filter bag is installed between the first mounting ring and the second mounting ring. The cooperation of the convex block and the notch prevents the opening edge of the filter bag from loosening between the first mounting ring and the second mounting ring. According to the length of the filter bag, the position of the support plate is changed through the sliding fit of the mounting rod and the mounting groove, so as to support the bottom of the filter bag through the support plate. When the pulse device of the dust collector blows air into the filter bag, the gas enters the filter bag and will push the bottom of the filter bag downward to generate a long deformation. The displacement of the bottom of the filter bag is restricted by the support of the support plate, thereby reducing the deformation of the filter bag and facilitating the prevention of the breakage of the dust removal filter bag.

[0018] 2. The present invention is provided with a frame structure. After the filter bag is installed, rotate the threaded rod, and drive the frame plate to move in the connecting frame through the threaded connection between the threaded rod and the frame plate. Thus, the inner wall of the filter bag is supported through the contact between the frame plate and the inner wall of the filter bag. By inserting the bolt into the positioning holes opened on the connecting frame and the frame plate, the position of the frame plate is fixed, so as to facilitate adjusting the position of the frame plate according to the diameter of the filter bag, and thus facilitate the use of filter bags with different opening diameters. At the same time, the frame structure does not need to be replaced when replacing the filter bag.

[0019] 3. The present invention is provided with a sliding connection between the mounting groove and the mounting rod. According to the length of the filter bag, the position of the support plate is changed, and at the same time, the fixing piece descends along the fixing rod. After the position of the support plate is determined, insert the bolt into the limiting holes opened on the fixing rod and the fixing piece to fix the position of the fixing piece, thereby fixing the position of the support plate, and thus facilitating the installation of filter bags with different lengths.

The auxiliary structure includes a support plate 5, a mounting block 6 and a fixed rod 7. A notch 17 is formed on the first mounting ring 2, a protrusion 18 is fixedly arranged at the lower end of the second mounting ring 3, and the protrusion 18 and the notch 17 cooperate with each other. The first mounting ring 2 and the second mounting ring 3 are bolted together;

[0030] The support plate 5 is detachably arranged on the connecting plate 4, and a frame structure is arranged on the second mounting ring 3. The frame structure includes a connecting frame 8, a threaded rod 9 and a frame plate 10. A plurality of connecting frames 8 are arranged, and the connecting frames 8 are arranged on the inner wall of the second mounting ring 3, and the connecting frames 8 are fixedly connected to the second mounting ring 3.

[0031] In this embodiment, the cooperation of the first mounting ring 2, the second mounting ring 3 and the filter bag body 1 constitutes the main structure of the entire dust removal filter bag.

[0032] More specifically, the auxiliary structure reduces the excessive deformation of the dust removal filter bag, thereby reducing the fracture of the dust removal filter bag, and the frame structure facilitates the support of filter bags with different opening diameters.

[0033] Please refer to Figures 1-5 As an embodiment for restricting the elongation deformation of the bottom of the filter bag: A plurality of connecting plates 4 are provided. Installation grooves 11 are formed in the connecting plates 4. Installation rods 12 are fixedly provided on the support plates 5. The installation rods 12 cooperate with the installation grooves 11. A plurality of installation blocks 6 and fixing rods 7 are provided. The installation blocks 6 are arranged at the side ends of the connecting plates 4. The installation blocks 6 are bolted to the connecting plates 4. A fixing piece 13 is fixedly provided at the side end of the installation rod 12. The fixing rods 7 are fixedly provided on the installation blocks 6. Through holes 14 matching with the fixing rods 7 are formed in the fixing piece 13.

A plurality of position-limiting holes 15 are formed in the fixing rods 7. Threads are provided inside the position-limiting rods. The position-limiting holes 15 provided on the fixing rods 7 and the position-limiting holes 15 provided on the fixing piece 13 are bolted together.

Threads are provided on the inner walls of the position-limiting pieces 16. The position-limiting pieces 16 are threadedly connected to the fixing rods 7. A plurality of position-limiting pieces 16 are provided;

[0034] Specifically, when installing the filter bag, the opening edge of the filter bag is installed between the first installation ring 2 and the second installation ring 3. The cooperation of the convex blocks 18 and the notches 17 prevents the opening edge of the filter bag from loosening between the first installation ring 2 and the second installation ring 3. According to the length of the filter bag, the position of the support plate 5 is changed through the sliding cooperation of the installation rods 12 and the installation grooves 11. According to the length of the filter bag, the position of the support plate 5 is changed, and at the same time, the fixing piece 13 is lowered along the fixing rod 7. After the position of the support plate 5 is determined, bolts are inserted into the position-limiting holes 15 formed in the fixing rods 7 and the fixing piece 13 to fix the position of the fixing piece 13, thereby fixing the position of the support plate 5, and thus the bottom of the filter bag is supported by the support plate 5. When the pulse device of the dust collector blows air into the filter bag, the gas enters the filter bag and will push the bottom of the filter bag to move downward to generate a relatively long deformation, but the displacement of the bottom of the filter bag is restricted by the support of the support plate 5.

[0035] Please refer to Figures 1-5 As an embodiment for the internal support of the filter bag: A threaded rod 9 is arranged on the connecting frame 8. The threaded rod 9 is rotatably connected to the connecting frame 8. A frame plate 10 is movably arranged on the connecting frame 8. The threaded rod 9 passes through the frame plate 10. The threaded rod 9 is threadedly connected to the frame plate 10. Positioning holes 19 are formed at the upper ends of both the connecting frame 8 and the frame plate 10. A plurality of positioning holes 19 are formed in the connecting frame 8. Threads are provided inside the positioning holes 19. The positioning holes 19 formed in the connecting frame 8 and the positioning holes 19 formed in the frame plate 10 are bolted together;

[0036] Specifically, after the filter bag is installed, the threaded rod 9 is rotated, and the frame plate 10 is driven to move in the connecting frame 8 through the threaded connection between the threaded rod 9 and the frame plate 10, so that the inner wall of the filter bag is supported by the contact between the frame plate 10 and the inner wall of the filter bag, and the position of the frame plate 10 is fixed by inserting bolts into the positioning holes 19 provided on the connecting frame 8 and the frame plate 10, so that the position of the frame plate 10 can be adjusted according to the diameter of the filter bag, and the inside of the filter bag body 1 can be expanded through the frame plate 10.

[0037] In summary, when used as a whole:

[0038] When installing the filter bag, the opening edge of the filter bag is installed between the first mounting ring 2 and the second mounting ring 3. The cooperation of the protrusion 18 and the notch 17 prevents the opening edge of the filter bag from loosening from the first mounting ring 2 and the second mounting ring 3. According to the length of the filter bag, the position of the support plate 5 is changed by the sliding cooperation of the mounting rod 12 and the mounting groove 11. According to the length of the filter bag, the position of the support plate 5 is changed, and the fixing plate 13 is lowered along the fixing rod 7. After the position of the support plate 5 is determined, the bolts are inserted into the limiting holes 15 opened on the fixing rod 7 and the fixing plate 13 to fix the position of the fixing plate 13, thereby fixing the position of the support plate 5, so as to support the bottom of the filter bag through the support plate 5. When the pulse device of the dust collector blows air into the filter bag, the gas enters the filter bag, which will push the bottom of the filter bag to move downward to produce a longer deformation, but the displacement of the bottom of the filter bag is limited by the support of the support plate 5.

[0039] When the filter bag is installed, the threaded rod 9 is rotated, and the frame plate 10 is driven to move in the connecting frame 8 through the threaded connection between the threaded rod 9 and the frame plate 10, so that the inner wall of the filter bag is supported by the contact between the frame plate 10 and the inner wall of the filter bag, and the position of the frame plate 10 is fixed by inserting bolts into the positioning holes 19 provided on the connecting frame 8 and the frame plate 10, so that the position of the frame plate 10 can be adjusted according to the diameter of the filter bag, and the inside of the filter bag body 1 can be expanded through the frame plate 10.

[0040] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded.

The scope of the present invention is defined by the attached claims and their equivalents.
