Description

Technical Field

[0001] The utility model relates to the field of dust removal filter bags, in particular to a portable anti-static dust removal filter bag. Background Art

[0002] The dust removal filter bag is a highly efficient dust removal filter material, which has good air permeability, high dust removal efficiency, and certain acid, alkali and heat resistance capabilities. During the weaving process, multi-sided flocking is adopted to increase the fabric thickness, making it elastic and having a very good dust removal effect, with a dust removal rate of up to 99.999%. The dust removal filter bag is made of polyester staple fiber or long fiber as raw material, and its service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, easy ash cleaning, and a dust removal efficiency of up to 98.99%. The filter bag is the heart of the bag dust collector during operation. Usually, the cylindrical pulse filter bag is vertically suspended in the dust collector. The dusty gas enters the dust collector from the air inlet, and through the baffle of the ash hopper, part of the large-particle dust in the gas is separated by the action of inertial force and directly falls into the ash hopper. The dusty gas enters the filter area of the filter bag in the box body. Most of the dust is trapped on the outer surface of the filter bag, while the clean gas passes through the filter material into the inside of the filter bag. After the purified gas passes through the filter bag opening and enters the upper box body, it is then discharged from the air outlet.

[0003] The authorized announcement number is CN 220802378 U, which is an anti-static dust removal filter bag. The installation barrel is composed of an installation ring, an annular convex block, a limiting block, a support rod, a cotton sleeve, a metal mesh, a bottom ring, a water tank, a hose, and a grounding wire. The limiting block is fixedly installed on the side surface of the installation ring, the support rod is fixedly installed at the bottom end of the installation ring, the cotton sleeve is sleeved on the outer surface of the support rod, the metal mesh is fixedly installed on the inner surface of the support rod, the bottom ring is fixedly installed at the bottom of the support rod, the water tank is detachably installed at the bottom of the bottom ring, the hose is detachably connected to the surface of the water tank, and the grounding wire is fixedly installed at the bottom of the bottom ring. This anti-static dust removal filter bag transfers the static electricity generated in the filter bag body to the ground through the support rod, the metal mesh, the bottom ring, and the grounding wire, and can generate a siphon phenomenon to actively absorb water through the cotton sleeve to make the device in a humid environment, so that it can prevent static electricity and remove dust.

[0004] After the anti-static dust removal filter bag is used for a period of time, it needs to be cleaned. Most of the existing anti-static dust removal filter bags are fixed by bolts, making it more troublesome to disassemble. Therefore, there is an urgent need in the market to develop a portable anti-static dust removal filter bag to help people solve the existing problems. Summary of the Utility Model

[0025] Furthermore, multiple hook-shaped support rods 103 are inserted into the anti-static dust filter bag 2 through the middle of the connecting ring 201. The anti-static dust filter bag 2 is stretched open by inserting multiple hook-shaped support rods 103 into the anti-static dust filter bag 2, so that the anti-static dust filter bag 2 maintains the maximum contact area with the air during operation, thereby improving the air filtration efficiency.

[0026] Furthermore, a plurality of springs 303 are fixedly connected between the upper end of the lower pressure ring 302 and the tightening ring 301 .

[0027] Furthermore, the fixed pipe connector 3 is inserted into the lower end of the outer side of the anti-static dust filter bag 2 and the connecting ring 201 is slid into the interior of the fixed pipe connector 3 and fits with the lower end of the tightening ring 301. The tightening ring 301 is pushed by the spring 303, so that the tightening ring 301 pushes the connecting ring 201 and the upper end of the fixed pipe seat 1 to clamp. When the anti-static dust filter bag 2 filters a lot of dust, the spring 303 is contracted by pulling the anti-static dust filter bag 2, and the anti-static dust filter bag 2 is released after pulling. The connecting ring 201 is pushed by the spring 303 to reset the anti-static dust filter bag 2. The dust can be partially shaken off by the vibration during the reset, thereby increasing the service life of the anti-static dust filter bag 2.

[0028] Furthermore, a fixing ring 101 is fixedly connected to the middle of the outer end surface of the fixed pipe seat 1, an external threaded portion 102 is provided at the middle upper end of the outer end surface of the fixed pipe seat 1, and an internal threaded portion 304 is provided at the middle lower end of the inner end surface of the fixed pipe connector 3.

A plurality of springs 303 are fixedly connected between the upper end of the pressing ring 302 and the tightening ring 301. The fixed pipe connector 3 is sleeved on the lower outer side of the anti-static dust removal filter bag 2 and the connecting ring 201 slides into the fixed pipe connector 3 and fits with the lower end of the tightening ring 301. By the spring 303 pushing the tightening ring 301, the tightening ring 301 is pushed to clamp between the connecting ring 201 and the upper end of the fixed pipe seat 1. When there is more dust filtered on the anti-static dust removal filter bag 2, the anti-static dust removal filter bag 2 is pulled to contract the spring 303. After pulling, the anti-static dust removal filter bag 2 is released, and the spring 303 is used to push the connecting ring 201 to drive the anti-static dust removal filter bag 2 to reset. Part of the dust can be shaken off through the vibration during reset, improving the service life of the anti-static dust removal filter bag 2. The upper end of the fixed pipe seat 1 is inserted into the fixed pipe connector 3, and the lower end of the fixed pipe connector 3 fits with the upper end of the fixed ring 101. The fixed pipe seat 1 and the fixed pipe connector 3 are fixedly connected by screwing the external thread portion 102 and the internal thread portion 304. When disassembly is required, the external thread portion 102 and the internal thread portion 304 are separated, and the fixed pipe connector 3 is pulled out, so that the anti-static dust removal filter bag 2 can be separated from the fixed pipe seat 1, improving the disassembly efficiency of the anti-static dust removal filter bag 2.
