A rotary oil fume purification device

Abstract

The invention discloses a rotational oil smoke purifying device. The device comprises a frame, wherein the frame comprises a horizontal plate, side vertical plates are arranged around the horizontal plate in the vertical direction, an upward bulging outer frame is welded in the middle of the horizontal plate, a fixed support is fixed at the top of the outer frame, and a drive motor is fixed in the middle of the fixed support; an oil screen support and an oil screen hub are fixed at an interval in a screen frame tensioning ring through bolts vertically sequentially, a stainless steel screen is fixed in the oil screen hub, and a central disc is fixed in the center of the stainless steel screen; a rotating shaft, arranged in the vertical direction, of the drive motor is fixedly connected with the oil screen support and the central disc; the screen frame tensioning ring is arranged in the outer frame, and a PM2.5 mass concentration sensor is mounted on the inner wall of the outer frame. The device operates stably, realizes uniform air intake and has stable resistance and flow.

Description

technical field [0001] The invention relates to a purification device, in particular to a rotary oil fume purification device. Background technique [0002] As people pay more attention to the indoor environment of the kitchen, the oil fume treatment device used in the family kitchen is generally a range hood with filtering and purification functions, while the oil fume treatment device used in the catering industry is generally a centralized smoke exhaust fan driven by a smoke exhaust fan. System, the filters that play a role in filtering and purifying in these two kinds of smoke exhaust systems are mainly divided into single-layer or double-layer impact-type grille structures. The impact-type simple filter can only intercept large particles of soot particles, but for The smaller the particle size, the poorer its filtering ability. Most of the fine particles are directly discharged outside, causing pollution to the environment. Or it is attached to the smoke exhaust fan, ...

[0002] As people pay more attention to the indoor environment of the kitchen, the oil fume treatment device used in the family kitchen is generally a range hood with filtering and purification functions, while the oil fume treatment device used in the catering industry is generally a centralized smoke exhaust fan driven by a smoke exhaust fan. System, the filters that play a role in filtering and purifying in these two kinds of smoke exhaust systems are mainly divided into single-layer or double-layer impact-type grille structures. The impact-type simple filter can only intercept large particles of soot particles, but for Particles with smaller particles have poorer filtering capabilities

Most of the fine particles are directly discharged outside, causing pollution to the environment

Or attached to the smoke exhaust fan, affecting the smoke exhaust effect and the service life of the range hood

[0003] In order to solve the above problems, the patent ZL200710051289X discloses a method for making an air smoke centrifugal purification device and its supporting filter disc. Purification ability of cutting fume particles

Patent CN103768875A also provides a new manufacturing method of the filter disc, although this method can ensure that the screen will not move, but the manufacturing method is complicated and the process cost is high
