Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filters, and specifically to a high-strength bag-type dust removal filter. Background Art

[0002] The bag dust filter is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust filter, the large particles and high specific gravity dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified. The cyclone high-efficiency bag dust filter usually uses the effect of induced draft fan to remove the dust-containing gas The gas is separated by the filter bag to achieve the purpose of purification; the existing cyclone type high-efficiency bag dust filter has a hollow cavity in the middle. When the mixed gas is introduced into the tank body, the mixed gas tends to gather in the middle of the tank body or the position where the gas is introduced, resulting in uneven filtering of the gas by the filter bags at different positions. Therefore, the number of times the filter bags in the middle or part are replaced is more frequent than the surrounding filter bags, thereby increasing the number of times the filter bags are replaced and increasing the labor of workers to repair the device, thereby reducing the working efficiency of the dust collector.

[0003] After searching, China disclosed a cyclone-type high-efficiency bag dust filter with patent publication number CN215311189U on December 28, 2021, which is roughly described as a cylinder, a cavity is opened inside the cylinder, a dispersion mechanism, the dispersion mechanism is connected to the inside of the cylinder, the dispersion mechanism includes a truncated cone body, a cavity is opened inside the truncated cone body, an induced draft duct, the induced draft duct is connected between the truncated cone body and the cylinder, an induced draft fan, the induced draft fan is installed inside the induced draft duct, and an exhaust hole, the exhaust hole is opened at the top of the induced draft duct, an exhaust mechanism, the exhaust mechanism is installed on the top of the cylinder, the dispersion mechanism also includes an air diffusion hole, the air diffusion hole is opened on the side wall of the truncated cone body, and a distributor fluid, the distributor fluid is connected to the inside of the truncated cone body through a bracket.

[0004] Although the above-mentioned prior art solution reduces the number of times the filter bag is replaced, saves manpower and material resources, and improves the dust removal efficiency and strength of the device, the dispersion mechanism of the device cannot be disassembled and is not convenient for cleaning. Long-term use can easily cause dust to accumulate in the exhaust holes and air holes, resulting in a reduction in the ventilation volume of the equipment and a reduction in the working efficiency and strength of the equipment.
