[0014] (Three) beneficial effects

[0015] The utility model provides film fluorine mei is staked felt filter bag, has the following beneficial effects:

[0016] (1) For membrane-coated fluoromethylene needle-punched felt filter bags, the system uses a counterweight, pull ring, and shrink rope. When replacing the membrane-coated fluoromethylene needle-punched felt filter bag, first, the old filter bag is pulled out of the installation port. When placing the new filter bag, the counterweight inside the filter bag body moves the filter bag body quickly into place due to gravity. At the same time, the size of the limiting body is larger than the installation port, preventing the filter bag body from falling into the installation port due to the weight of the counterweight. The bottom of the limiting body is sealed. The sealing ring overlaps with the installation port to prevent dust from overflowing into the machine. When replacing the membrane-coated fluoropolymer needle-punched felt filter bag, first pull up the pull ring. The pull ring drives the pull rope and the shrink rope, which shrinks the top of the filter bag body. This prevents dust from overflowing when the membrane-coated fluoropolymer needle-punched felt filter bag is pulled out, thus preventing workers from inhaling too much dust. At the same time, the pull ring driving the pull rope and the shrink rope also makes it easier and faster to pull out the membrane-coated fluoropolymer needle-punched felt filter bag.
