Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically a medium-temperature coated filter bag based on fiberglass fabric. Background Technology

[0002] Medium-temperature coated fiberglass filter bags are a common filtration material used in industrial applications, typically in dust removal equipment to capture dust and solid particles. Fiberglass base fabric is a material woven from glass fiber yarns, possessing excellent high-temperature resistance and chemical stability, thus it is often used in filtration applications in high-temperature environments. Medium-temperature coating refers to covering the surface of the fiberglass base fabric with a wear-resistant and chemically resistant polymer coating. This coating provides additional protection and extends the service life of the filter bag.

[0003] A search revealed a patent, CN222196292U, which discloses a fiberglass-based fabric medium-temperature membrane filter bag. The bag includes a filter bag body with a fixed ring at its upper end and two connecting rods fixed at its lower end. A drive chamber is fixedly connected to the lower ends of the two connecting rods. A rack is slidably connected to the drive chamber via a track structure. A half-gear is meshed with the rack, and a motor is fixedly connected to the half-gear within the drive chamber. A support plate is fixedly installed within the drive chamber. A limiting plate is fixedly installed on the rack, and a first spring is fixedly connected between the limiting plate and the support plate. Two movable seats are fixedly installed on the rack. A striking frame is installed at the upper end of each movable seat, passing through the drive chamber. A moving groove that mates with the movable seat is provided at the upper end of the drive chamber. Multiple striking blocks are fixedly installed on the striking frame, causing the striking blocks to continuously strike and clean the filter bag body, knocking off dust adhering to the filter bag body and thus ensuring the filtration effect.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe the installation of the filter bag by setting a fixing ring at the opening of the filter bag and using a bevel gear and a bevel gear ring for engagement. However, in reality, the fixing ring needs to be fixedly connected to the filter bag. If the fixing ring is sewn onto the filter bag, the entire ring needs to be replaced when the filter bag is replaced, which increases the cost of filter bag replacement. Therefore, there is an urgent need in the art to improve the filter bag to overcome the shortcomings of the prior art. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1-6 A fiberglass-based medium-temperature coated filter bag includes a filter bag body 1 fixedly mounted on a mounting base plate 4. The filter bag body 1 has a first connecting cloth ring 2 and a second connecting cloth ring 3 on each of its two ends. The upper side of the filter bag body 1 opening has a fixed bracket 5 adapted to and fixedly mounted on the mounting base plate 4, and a compression clamping bracket 6 adapted to the mounting base plate 4 and the fixed bracket 5. The compression clamping bracket 6 is inclined to the side facing the fixed bracket 5. The lower end of the filter bag body 1 is tightly abutted against a bottom plate 7 adapted to the fixed bracket 5. Several threaded connecting rods 8 pass through the bottom plate 7. The frame 6 has several connecting holes 9 that are threaded to the ends of the connecting threaded rods 8. The connecting threaded rods 8 have locking rings 11 on their sides for pressing the second connecting cloth ring 3. A pressing ring 10 is fitted between the sides of the several connecting threaded rods 8. The pressing ring 10 presses the second connecting cloth ring 3. One side of the locking ring 11 is in close contact with the pressing ring 10. The filter bag body 1 has several positioning cloth sleeves 12 on its side. The connecting threaded rods 8 pass through the several positioning cloth sleeves 12. The fixed bracket 5, the base plate 7 and the pressing ring 10 all have waist-shaped grooves 22 that are adapted to the connecting threaded rods 8.

[0031] The specific implementation method in this embodiment is as follows: The filter bag body 1 is a medium-temperature coated filter bag made of fiberglass base fabric. Fiberglass base fabric is a material woven from glass fiber yarn, which has excellent high-temperature resistance and chemical stability. Therefore, it is often used for filtration applications in high-temperature environments. Medium-temperature coating refers to covering the surface of the fiberglass base fabric with a wear-resistant and chemically resistant polymer coating. This coating provides additional protection and extends the service life of the filter bag. The first connecting cloth ring 2 and the second connecting cloth ring 3 on both sides of the filter bag body 1, as well as several positioning cloth sleeves 12 on its sides, are all fixed by sewing. When the filter bag body 1 needs to be installed, the first connecting cloth ring 2 is bent and pressed tightly against the side of the fixed bracket 5, and the compression clip 6 is clipped between the mounting base plate 4 and the fixed bracket 5. The fixed bracket 5 and the compression clip 6 are inclined in a matching manner on opposite sides. The compression ring 10 is sleeved on the side of the filter bag body 1, and the second connecting cloth ring 3 is bent and compressed. The tightening ring 10 is tightly attached, and the connecting threaded rod 8 passes through the base plate 7, the second connecting cloth ring 3, the positioning cloth sleeve 12, and the fixing bracket 5. The upper end of the connecting threaded rod 8 is threadedly connected to the connecting hole 9 on the compression clamping frame 6. The tightening ring 10 is pressed by rotating the locking ring 11. While tightening the locking ring 11, the connecting threaded rod 8 is pulled down. Since the side of the connecting hole 9 is inclined, the compression clamping frame 6 compresses the filter bag body 1, and one side of the connecting hole 9 is clamped to the side of the mounting base plate 4, pressing and fixing the upper part of the first connecting cloth ring 2, thereby fixing the filter bag body 1. When the filter bag body 1 needs to be replaced, the locking ring 11 is loosened, the connecting threaded rod 8 is carefully disassembled, and the compression clamping frame 6 is removed, so that the filter bag body 1 can be replaced. When replacing the filter bag body 1, only the filter bag body 1 needs to be replaced, and other parts can be reused, reducing the cost of replacing the filter bag. The waist-shaped groove 22 is set to facilitate the insertion of the connecting threaded rod 8.

[0032] Example 2

[0033] Please see Figure 4 This embodiment includes the above embodiment, and further includes: two symmetrical threaded blocks 13 that are adapted to the side threads of the connecting threaded rod 8 are provided inside the locking ring 11; the opposite side walls inside the locking ring 11 are provided with movable grooves 14 adapted to the threaded blocks 13; an elastic element 15 with elasticity is provided between the side of the threaded block 13 and the inner side wall of the movable groove 14; a connecting post 17 that passes through the locking ring 11 is fixedly installed on one side of the threaded block 13; the elastic element 15 is sleeved on the side of the connecting post 17; a pull plate 18 is fixedly installed at the end of the connecting post 17 away from the threaded block 13; an opening groove 16 adapted to the pull plate 18 is opened on the side of the locking ring 11; a number of pins 19 pass through the upper part of the locking ring 11; a number of slots 20 adapted to the pins 19 are opened on the upper part of the threaded block 13; and a connecting rod 21 is fixedly installed between the upper ends of two pins 19.

[0034] In this embodiment, the specific implementation method is as follows: When locking the locking ring 11, firstly, the two pull plates 18 are pulled in opposite directions. The pull plates 18 drive the threaded blocks 13 to move within the moving groove 14 via the connecting post 17. At the same time, the threaded blocks 13 compress the elastic element 15, which is specifically a spring. The two threaded blocks 13 disengage from the side of the connecting threaded rod 8. At this time, the locking ring 11 can move up and down rapidly on the side of the connecting threaded rod 8. Push the base plate 7 downwards until it can no longer be pushed. Then, release the two pull plates 18. The elastic force of the elastic element 15 pushes the threaded blocks 13 closer to the connecting threaded rod 8, and the threaded blocks... The threads on the side of the threaded block 13 engage with the threads on the side of the connecting threaded rod 8. Rotating the locking ring 11 pulls the connecting threaded rod 8 closer, and the elastic element 15 is sleeved on the side of the connecting post 17 to prevent vertical and radial deformation of the elastic element 15. After tightening the connecting threaded rod 8, the two pins 19 pass through the locking ring 11 through the connecting rod 21 and their ends are inserted into the slot 20 to limit and fix the position of the threaded block 13, thereby improving the stability when the threaded block 13 engages with the side of the connecting threaded rod 8. The locking ring 11 can quickly slide on the side of the connecting threaded rod 8, which is convenient for the installation of the filter bag body 1 and subsequent maintenance and replacement.
