Filter bag detachment prevention and sealing device of electric pulse bag filter

Abstract

The invention discloses an anti-drop and sealing device for a filter bag of an electropulsing bag type dust collector. The anti-drop and sealing device for the filter bag comprises a cylinder, wherein the thickness of a cylinder wall is 1 to 5cm; a ring groove is arranged inside the cylinder wall; the size of the ring groove is suitable for embedding of the edge of a filter bag mouth; meanwhile, an elastic part is arranged inside the ring groove; the lower side surface of the ring groove is an inclined plane, wherein the inclined plane and a horizontal plane form an angle of 2 to 6 degrees; the edge of a ring groove opening is not a seamed edge, but is a circular arc transition; and the diameter of a circular arc is equal to the external diameter of the cylinder. The device provided by the invention has the following advantages: the filter bag can be connected with an air outlet of the electropulsing bag type dust collector in cooperation with the anti-drop and sealing device, so the connection of the filter bag and the dust collector is more firmly; sealing property is good; the problems like dust leakage from the outer edge of the filter bag and dropping of the filter bag can be completely eradicated; environment pollution is effectively reduced; and operation troubles of the dust collector are decreased.

Description

technical field [0001] The invention relates to the field of anti-off sealing of filter bags, more specifically, the invention relates to an anti-off sealing device for filter bags of electric pulse bag filter. Background technique [0002] The filter bag of the current electric pulse bag filter is directly set on the porous plate on the top of the filter, such as figure 1 As shown, the filter bag 2 is directly set on the perforated plate 1, but because the contact area between the filter bag 2 and the perforated plate is small and cannot be tightly attached, and the dust suction fan must also run when the dust collector is running, the filter bag 2 is under strong wind speed. And under the impact of frequent pulses, it will swing continuously, which will easily cause ash leakage at the contact between filter bag 2 and perforated plate 1. Part of the ash leakage will be sucked out by the fan and discharged into the air to pollute the environment, while the other part will fa...

Problems solved by technology

[0002] The filter bag of the current electric pulse bag filter is directly set on the porous plate on the top of the filter, such as figure 1 As shown, the filter bag 2 is directly set on the perforated plate 1, but because the contact area between the filter bag 2 and the perforated plate is small and cannot be tightly attached, and the dust suction fan must also run when the dust collector is running, the filter bag 2 is under strong wind speed. And under the impact of frequent pulses, it will swing continuously, which will easily cause ash leakage at the contact between filter bag 2 and porous plate 1. Part of the ash leakage will be sucked out by the fan and discharged into the air to pollute the environment, while the other part will fall into the filter bag 2

With the prolongation of the operation time of the dust collector, more and more dust will accumulate in the filter bag, and the weight of the filter bag will also continue to increase, eventually causing the entire filter bag to fall off due to overweight, and the equipment cannot operate normally
