Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and particularly relates to a self-cleaning dust removal filter bag. Background Art

[0002] Dust filter bags are a kind of efficient dust filter material, which are widely used in bag dust collectors. They are mainly used to filter and capture particulate matter and dust in the air, which can purify the air, protect the environment and human health. Dust filter bags are made of various materials, including polyester staple fiber, PPS fiber, PP polypropylene, aramid fiber, and nylon fiber. These materials have good air permeability, high dust collection rate, and easy cleaning, which makes the dust removal efficiency of dust filter bags reach more than 98.99%, and some dust filter bags can even reach 99.999%. The service life of dust filter bags is generally 4 to 6 times that of glass fiber fabrics, thanks to their good acid, alkali and heat resistance, as well as the multilateral brushing technology used in the weaving process, which increases the thickness of the fabric, makes it elastic, and has a very good dust removal effect.

[0003] Publication number "CN210964325U" is a bag dust collector that is easy to maintain, including a base, a base frame is fixedly installed on the top of the base, a body is fixedly sleeved inside the top of the base frame, the top of the body is located above the base frame, and a cross plate is fixedly installed inside the body. This bag dust collector that is easy to maintain is provided with a supporting shell and a through-port. Due to the design of the supporting shell, the supporting area of ​​the filter cloth is increased, so that the supporting effect of the filter cloth is improved. At the same time, due to the uniform design of the through-port, dust-containing gas or high-pressure pulse gas can pass smoothly. Compared with the traditional vertical pole frame, the through-port limits the flow area of ​​the airflow, thereby increasing the flow rate of the high-pressure pulse gas and increasing the disturbance effect on the filter cloth, so that the dust removal effect of the filter cloth is improved, thereby increasing the practicality of the bag dust collector.

[0004] Although the above-mentioned new type increases the flow rate of high-pressure pulse gas and increases the disturbance effect on the filter cloth, so that the dust removal effect of the filter cloth is improved, thereby increasing the practicality of the bag dust collector, when cleaning the dust attached to the outer surface of the filter cloth, the high-pressure pulse gas cannot evenly and effectively remove the dust attached to the filter cloth, thereby affecting the dust removal effect, and the filter cloth area close to the air jet may be subjected to greater pressure, resulting in increased wear. This not only shortens the service life of the filter bag, but may also affect the overall performance of the dust collector. Utility Model Content
