Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a device capable of replacing a cylinder of an environmentally friendly dust collector online. Background Art

[0002] A bag dust collector is a dry dust filtering device that is suitable for capturing fine, dry, non-fibrous dust. The valve plate of the clean air chamber in a bag dust collector is generally controlled to open and close by a cylinder.

[0003] In existing dust collectors, the valve plate is generally directly connected to the piston rod of the cylinder, which results in the cylinder being installed at a very low position. When the cylinder fails and needs to be replaced, the staff needs to disassemble and replace it at the bottom of the cylinder, which brings great inconvenience to the maintenance and replacement work. In addition, when replacing the cylinder, the dust collector needs to be shut down, which affects its normal working use.

[0004] In order to facilitate the replacement of the cylinder, after searching, the utility model patent with publication number CN207195690U in the prior art disclosed a dust collector lifting valve, including a support seat; the support seat is installed on the dust collecting top plate, and the upper end of the support seat is equipped with a cylinder through a fixing bolt, the telescopic rod of the cylinder is connected to the lifting rod through a connecting sleeve, the lifting valve plate is installed at the lower end of the dust collecting top plate, and the lifting rod passes through the dust collecting top plate and is connected to the lifting valve plate.

[0005] When replacing the cylinder, it is necessary to loosen the fixing nuts and connecting sleeves of the cylinder rod and the lifting rod, remove the cylinder fixing screw, and then replace the cylinder. However, during use, the operation of the cylinder will cause the cylinder rod and the lifting rod to vibrate, which can easily lead to loosening between the fixing nuts and the connecting sleeve, thereby affecting the movement accuracy of the valve plate, thereby affecting the sealing of the clean air chamber in the dust collector when it is closed.
