Description
Technical Field
The utility model relates to a automatically cleaning filter screen in dust collecting equipment field.
Background
The filter is the main part of the dust collecting equipment, a great amount of dust particles can be adsorbed on the inner wall of the filter screen when the dust collector works, the permeability of the filter screen is reduced along with the accumulation of a great amount of dust on the inner wall of the filter screen, the filtering effect is influenced,
the cleaning and maintenance are required to be carried out regularly, which brings inconvenience to the use and also improves the maintenance and use cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a self-cleaning filter screen which has simple and compact structure, convenient and quick operation and good filtering effect.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
the utility model provides a automatically cleaning filter screen, includes filter screen and cleaning device, and cleaning device installs in the filter screen its characterized in that: the filter screen is in a conical shape and is formed by enclosing folded hard filter paper, and the filter paper is folded into a conical wave surface; the cleaning device comprises a fixing frame, a rotating shaft, a scraping blade and a handle shaft, wherein the fixing frame is fixed on an upper cover of the filter screen, the rotating shaft is arranged at the axis position of the filter screen through the fixing frame, the scraping blade is arranged on the rotating shaft, the handle shaft drives the scraping blade to rotate in the filter screen, the scraping blade stirs a conical wave surface on the inner wall of the filter screen, the inner wall of the filter screen generates elastic vibration, so that dust on the inner wall of the filter screen falls into a dust collection barrel at the bottom of the filter screen, the filter screen formed by enclosing of conical wave surface hard filter paper has certain rigidity, the rigidity strength of the filter screen is improved, the inner wall of the filter screen of the conical wave surface can generate elastic vibration when the scraping blade is; the technical scheme is further explained as follows: the scraping sheet is a flexible rubber sheet, so that the filter screen cannot be abraded when the inner wall of the filter screen is stirred; the technical scheme is further explained as follows: a sealing ring is arranged between the upper cover of the filter screen and the filter screen; the technical scheme is further explained as follows: the scraping sheet contacts the conical wave surface on the inner wall of the filter screen.
The utility model discloses an automatically cleaning filter screen has simple structure compactness, and convenient operation is swift and characteristics such as filter effect is good.
