Description

Technical Field

[0001] The utility model relates to the technical field of dust removal bags, in particular to a polytetrafluoroethylene emulsion dust removal bag. Background Art

[0002] PTFE, or polytetrafluoroethylene, is a material with excellent chemical stability, high temperature resistance, low friction coefficient and good self-cleaning ability. These characteristics enable PTFE dust bags to operate stably for a long time in the high temperature, high humidity and high corrosive environment of steel mills, effectively filter smoke and protect the environment and equipment.

[0003] After searching, the patent document with publication number: CN215610016U discloses a polytetrafluoroethylene emulsion modified dust bag, which installs a sealing strip and Velcro at the bottom of the bag body so that one side of the zipper can be sealed by the sealing strip to prevent dust from being discharged into the air through the gap of the zipper, which is convenient for discharging dust and improves the sealing of the bag body; by installing a tightening mechanism on the tightening rope, when the bag body is installed, the pressure plate is pulled out, the tightening rope is tightened, and then the pressure plate is reset to fix the tightening rope, thereby improving the efficiency of bag installation. In actual use, when cleaning the dust inside the above-mentioned dust bag, it is necessary to open the zipper for cleaning, which is more cumbersome to clean the inner wall of the dust bag, especially when multiple dust bags are arranged, and there is no supporting structure. When ventilated, it is easily affected by the direction of the airflow, resulting in large bending or shaking. Therefore, we propose a polytetrafluoroethylene emulsion dust bag to solve the above problems. Utility Model Content

[0022] 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 of 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.

[0023] Depend on Figure 1-Figure 5 As shown, it relates to a polytetrafluoroethylene emulsion dust removal bag, including a bag body 1, the bag body 1 is made of polytetrafluoroethylene emulsion material, a bag head 2 is fixedly connected to the top of the bag body 1, an annular groove 3 is opened on the outer wall of the bag head 2, and an elastic metal sheet 4 is placed on the inner wall of the annular groove 3. The elastic metal sheet 4 is made of stainless steel and has elastic reset ability after bending, and has large elasticity, which mainly drives the bag head 2 to be fixed in the top plate 8.

[0024] A bag hole is opened on the outer wall of the bag head 2, and a braided rope 5 is slidably connected to the inner wall of the bag hole. A spring snap 6 is installed on the outer wall of the braided rope 5. The spring snap 6 is an existing mechanical fastener, which is usually composed of several main components, including a spring, a gear, a tooth groove, etc. When two objects need to be connected, the gear of the spring snap 6 will enter the tooth groove and lock the two objects to form a firm connection.

[0025] The outer wall sliding sleeve of the bag head 2 is provided with a top plate 8, and the bottom of the top plate 8 is provided with an annular mounting groove for placing the bag head 2. The inside of the top plate 8 is fixedly connected to an air guide tube 7, and the air guide tube 7 is located inside the bag body 1. The inner wall of the top plate 8 is fixedly connected to a cross frame 9, and the cross frame 9 is used to support the threaded sleeve 10 and the threaded rod 11.

[0026] An adjustment mechanism is provided at the bottom of the cross frame 9, and the adjustment mechanism includes a threaded sleeve 10. The bottom of the cross frame 9 is fixedly connected to the top of the threaded sleeve 10. The inner wall of the threaded sleeve 10 is threadedly connected to a threaded rod 11, and the threaded rod 11 is retracted and retracted through the threaded sleeve 10. The bottom fixed sleeve of the threaded rod 11 is provided with a docking sleeve 13, and the outer wall of the docking sleeve 13 is fixedly connected to a chassis 14. The bottom of the chassis 14 contacts the inner wall of the bag body 1, and the chassis 14 supports the bag body 1 to straighten it to prevent the bag body 1 from bending and shaking. The outer wall of the chassis 14 is fixedly connected to two support rods 12, and one end of the two support rods 12 is fixedly connected to the outer wall of the threaded rod 11.

[0027] Working principle: When in use, place the bag body 1 into the assembly hole of the equipment, rotate the threaded rod 11 to make the threaded rod 11 extend and retract through the threaded sleeve 10, and adjust the upper and lower positions of the chassis 14 to support bags 1 of different lengths. When the chassis 14 contacts the bottom inner wall of the bag body 1, stop rotating the threaded rod 11, pull the two ends of the braided rope 5, and make the two ends of the elastic metal sheet 4 close together and shrink, so that the circle of the bag head 2 becomes smaller, and then use the spring snap 6 to ensure the contraction of the braided rope 5 to prevent it from sliding into the bag hole. In order to place the bag head 2 into the top plate 8, press the spring snap 6 to loosen the braided rope 5, so that the elastic metal sheet 4 is reset by its own elastic force, and the elastic metal sheet 4 drives the bag head 2 to be fixed in the top plate 8, and the top plate 8 and the bag head 2 are placed above the assembly hole, and the bag body 1 is located in the assembly hole. When dust removal is performed, the airflow carrying dust passes through the outer surface of the bag body 1 for filtering, the filtered dust is located on the outer surface of the bag body 1, and the filtered gas flows out of the bag body 1. When cleaning subsequently, it is only necessary to shake the bag body 1.
