Description

Technical Field

[0002] Antistatic filter bags are usually used in filtration systems to reduce static electricity accumulation, improve filtration efficiency and ensure equipment safety. Such filter bags are common key components in industrial applications, especially when dealing with flammable dust or particles.

[0003] For traditional filter bags, due to the lack of a fixed function, they are prone to deformation during pulse cleaning or dust suction, which will affect the filtration performance and structural integrity of the filter bag, making it impossible to effectively remove dust in some areas, reducing the filtration efficiency. Moreover, when the filter bags are not fixed, the static electricity generated by mutual friction is extremely dangerous.

[0004] Secondly, if the filter bag installation does not have a quick replacement function, the replacement and maintenance process may be more complex and time-consuming, increasing the operating cost and labor intensity. Frequent deformation and uneven wear may accelerate the aging and damage of the filter bag, resulting in more frequent replacement. Content of the Utility Model

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figures 1-5, An antistatic filter bag, comprising a main body 1, a shape fixing mechanism and an installation and disassembly mechanism. The shape fixing mechanism includes a bag body 2, an inner lining ring 3, an outer lining ring 4, a sealing screw sleeve 5 and a pulse device 6. The bag body 2 is installed inside the main body 1 and is detachably connected to the main body 1. The inner lining ring 3 and the outer lining ring 4 are cooperatively connected and installed on the bag body 2. The bag body 2 is detachably connected to the pulse device 6. The sealing screw sleeve 5 is threadedly engaged with the pulse device 6 and is detachably connected to the bag body 2. The installation and disassembly mechanism includes an inner clamping block 7, an outer clamping block 8, a bolt 9, a first spring 10, a spring plate 11 and a fixing mechanism. The inner clamping block 7 and the outer clamping block 8 are installed on the bag body 2 by the bolt 9 and are detachably connected to the bag body 2. The first spring 10 is installed inside the main body 1, and its two ends are respectively fixedly connected to the main body 1 and the spring plate 11. The spring plate 11 is installed inside the main body 1 and is respectively slidably connected to the main body 1 and is detachably connected to the inner clamping block 7 and the outer clamping block 8.

[0030] In this embodiment, the shape fixing mechanism includes a bag body 2, an inner lining ring 3, an outer lining ring 4, a sealing screw sleeve 5 and a pulse device 6. During use, one end of the bag body 2 is installed on the connection port 18 of the pulse device 6, and the sealing screw sleeve 5 is installed on the periphery of the bag body 2, so that one end of the bag body 2 is fixed on the pulse device 6. The outer lining ring 4 is sleeved outside the bag body 2. Subsequently, the inner lining ring 3 is placed inside the bag body 2 corresponding to the outer lining ring 4. Then, the inner lining ring 3 is pressed, so that the engaging block 19 on the inner lining ring 3 enters the engaging groove 20 inside the outer lining ring 4, making the engaging block 19 on the inner lining ring 3 and the engaging block 19 on the outer lining ring 4 fit tightly, ensuring that the bag body 2 will not undergo large deformation and generate huge gaps during dust absorption and pulse cleaning, thereby reducing the dust removal effect.

[0031] In this embodiment, the installation and disassembly mechanism includes an inner clamp block 7, an outer clamp block 8, a bolt 9, a first spring 10, a spring plate 11 and a fixing mechanism. When in use, the inner clamp block 7 and the outer clamp block 8 are placed at the bottom of the bag body 2, and then the bolt 9 is inserted into the connecting hole 22 in the outer clamp block 8, and then the inner clamp block 7 and the outer clamp block 8 are fixed to the bottom of the bag body 2, and the installed inner clamp block 7 and the outer clamp block 8 are placed on the spring plate 11, and then the spring plate 11 is pressed to compress the first spring 10. In this process, the toggle plate 23 is pulled to make the connecting rod 14 slide in the fixed slide groove 17, and the fixing block 13 is pulled to compress the second spring 12, so that the fixing block 13 is moved forward. The bag 2 is then moved into the main body 1 and the spring plate 11 is completely compressed by the inner and outer clamping blocks 7 and 8 and then moved into the main body 1. The toggle plate 23 is then released and the fixing block 13 is then moved into the notch 21 in the outer clamping block 8 and then the bottom of the bag 2 is fixed. The compressed first spring 10 also applies pressure to the fixing block 13 and then the inner and outer clamping blocks 7 and 8 are firmly fixed. During this process, the sealing plate 15 is always on the fixing groove 17 to cover the fixing groove 17 and prevent dust from entering. After the bag 2 is fixed as a whole, dust suction or pulse cleaning is started. When the dust falls off due to pulse cleaning, the dust suction port 16 on the main body 1 generates suction to suck the dust in for disposal.

[0032] Embodiment 2:

[0033] In summary, when in use, first install and fix the bag body 2, install one end of the bag body 2 on the connection port 18 of the pulse device 6, and install the sealing screw sleeve 5 on the periphery of the bag body 2, so that one end of the bag body 2 is fixed on the pulse device 6, put the outer liner 4 on the outside of the bag body 2, and then put the inner liner 3 into the bag body 2 corresponding to the outer liner 4, and then press the inner liner 3 so that the bite block 19 on the inner liner 3 enters the bite groove 20 inside the outer liner 4, so that the bite block 19 in the inner liner 3 and the outer liner 4 are engaged with each other. The bite block 19 in the lining ring 4 fits tightly to ensure that the bag body 2 will not deform greatly during absorption and pulse cleaning, thereby generating a huge gap and reducing the dust removal effect. At this time, the inner clamp block 7 and the outer clamp block 8 are placed at the bottom of the bag body 2, and then the bolt 9 is inserted into the connecting hole 22 in the outer clamp block 8, and then the inner clamp block 7 and the outer clamp block 8 are fixed to the bottom of the bag body 2, and the installed inner clamp block 7 and the outer clamp block 8 are placed on the spring plate 11, and then the spring plate 11 is pressed, so that the first spring 10 is compressed, and at this During the process, the toggle plate 23 is pulled to make the connecting rod 14 slide inside the fixed slide groove 17, and the fixing block 13 is pulled to compress the second spring 12, so that the fixing block 13 enters the inside of the main body 1. When the inner clamping block 7 and the outer clamping block 8 completely compress the spring plate 11 into the main body 1, the toggle plate 23 is released at this time. Under the action of the second spring 12, the fixing block 13 enters the notch 21 in the outer clamping block 8, thereby fixing the bottom of the bag body 2, and the compressed first spring 10 also applies pressure to the fixing block 13. The bag body 2 at this time will not produce gaps due to deformation, thereby reducing the dust collection effect, and there will be no friction between the fixed bag bodies 2, and secondly, it is convenient and quick to install.

[0034] 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 are not described one by one here. In the above, all fixed connections are preferably welded.
