3results about How to "Avoid affecting the dust removal effect" patented technology

The utility model discloses a combined filter dust collector, including its including base subassembly, and base subassembly includes bottom plate, fan shell, air outlet, dust removal box and air inlet frame. The utility model has the advantages that: through the setting of the filter, the filter plate and the filter bag are inserted into the inner cavity of the slide rail by the sliding block, so that the filter plate is installed and positioned. During the dust removal process, the external air is drawn into the inner cavity of the dust removal box. When the air is drawn into the inner cavity of the dust removal box, the filter plate is used to filter and intercept the impurities in the air. The dust after interception is adsorbed on the surface of the filter plate. The dust on the surface of the filter plate can be cleaned by the cleaning piece. The garbage after cleaning falls into the inner cavity of the filter bag through the filter plate, and the dust is collected by the filter bag. Therefore, the dust intercepted on the surface of the filter plate can be effectively collected, and the filter plate is prevented from being blocked to affect the dust removal effect.

This invention relates to the field of dust removal, and more particularly to a pulse dust collector for heavy calcium carbonate powder production. The collector includes an outer frame, a dust hopper mounted on the lower side of the outer frame, a filter bag mounted on the upper side of the outer frame, an air pipe connected to the upper inner side of the outer frame, an air outlet corresponding to the filter bag located on the upper side of the filter bag, an air bag mounted on the side wall of the outer frame, a pulse valve mounted on the air pipe connected to the air bag, and an air inlet connected to the lower side of the outer frame. This invention uses a pulse valve to blow dust from the filter bag to ensure its working efficiency. A baffle initially blocks the gas entering through the air inlet, causing some dust to settle. A filter screen is provided to preliminarily remove dust from the gas upon contact with the filter bag, reducing the workload on the filter bag. A scraper is provided to remove dust from the filter bag.

The utility model discloses a cleaning device for PVC film printing, and belongs to the technical field of PVC film cleaning. The guiding assembly is installed in the frame and used for enabling the PVC film to penetrate through the frame; the two cleaning assemblies are mounted in the frame and used for cleaning the surface of the PVC film; wherein the two cleaning assemblies are located on the two sides of the PVC film respectively, pollutants on the two faces of the film material are synchronously treated through the two-way negative pressure suction design, the overturning requirement of traditional single-face cleaning is avoided, meanwhile, the residue problem generated in the cleaning process can be avoided, and the cleaning effect is improved.
