Description
Technical Field
The invention belongs to the technical field of industrial dust removal equipment, and particularly relates to a pleated filter cartridge dust remover, a filter cartridge frame of the pleated filter cartridge dust remover and a using method of the frame.
Background
A pleated filter cylinder dust remover is a dry dust filtering device which is suitable for collecting fine and dry dust and adopts the principle that the filtering action of fiber fabrics is utilized to filter dust-containing gas. In the filtering process, the dusty gas flows from the outer side to the inner side of the filter material, the dust with large particles and large specific gravity is settled under the action of gravity and falls into the ash hopper, and the fine dust is filtered and collected by the filter material when passing through the filter material along with the airflow. The pleated filter cartridge dust remover is widely applied to a plurality of industrial fields due to the advantages of high dust removal efficiency, large air handling capacity, stable operation performance and the like. However, the filter material is soft and is easy to deform under the pressure effect generated by suction and blowing of the fan; therefore, a net-shaped frame structure is arranged in a filter material of the filter cylinder in the commonly used pleated filter cylinder dust remover at present, so that the support filter material cannot be pressed to generate large deformation, but the pleats and the pleats are still deformed and bonded together under the action of pressure generated by suction and blowing of a fan, the filtering effect of the filter material is reduced, and meanwhile, when the dust adhered to the filter material is cleaned in the later period, the cleaning effect is greatly reduced.
Chinese patent application No. 201210293916.1, published as patent application No. 2013, 3-6, discloses a filter cartridge for use with a pleated filter cartridge. The filter element includes a tubular body having a first end and a second end. The tubular body includes a plurality of surface features spaced longitudinally along the tubular body between the first end and the second end. Each surface feature comprises a first portion for flow area and a second portion for bridging across the opening for strength; according to the technical scheme, the filter element is used for supporting the filter cylinder, but the filter element is arranged in the filter channel in the filter cylinder, so that the filter cylinder can only realize that the whole pleated object (namely the filter material) on the filter cylinder is not deformed, and under the action of wind pressure, the local deformation between pleats still influences the filtering effect and the dust cleaning work of the filter material.
Chinese patent application No. 201620691488.1, published 2016, 12, 28, discloses a novel pleated filter cartridge, belonging to the field of air filtration. The pleated filter cylinder comprises a top cover, a cylinder body and a bottom cover, wherein a through hole is formed in the top cover, and two ends of the cylinder body are fixedly connected to the top cover and the bottom cover respectively; the cylinder body is of a pleated structure; on the cross section of the cylinder, the outer edge and the inner edge of the cylinder are respectively positioned on an ellipse; the surface of the cylinder body is provided with a filter medium layer which is of a pleated structure. The novel pleated filter cylinder can remove peculiar smell in air and absorb volatile organic compounds, and the filtering efficiency is improved. The utility model discloses a barrel of its pleat structure on the one hand among the disclosed technical scheme receives the wind pressure easily to produce and warp, appears the problem of the influence filter effect and the dust cleaning work of foretell, and on the other hand, no matter the top of the barrel of pleat structure is connected the part with the top cap, still the bottom is connected the part with the bottom, and the laying dust between its pleat and the pleat is difficult to the clearance, and long-time dust is piled up and is leaded to straining a section of thick bamboo bottom performance failure, is unfavorable for the operation of dust remover equipment.
