Problems solved by technology

Due to the static structure, the fixed filter screen can only passively contact the oil fume, the contact range is small, and cannot fully contact all the oil fume, the condensation and sedimentation efficiency is not high, and the purification effect is limited
And the condensed oil is easy to accumulate and form scale, which is not easy to clean
Sometimes the condensed and condensed oil fume droplets on the windward side of the net cover will directly drip onto the frying pan under the action of gravity, which is especially serious in winter when the temperature is cold

Embodiment Construction

[0025] exist figure 1 In the shown embodiment, the dual-shaft output motor is fixed on the bracket at the throat of the Venturi tube purification device, the impeller is installed on one shaft end, and the present invention is installed on the other shaft end. The motor shaft passes through the central circular tube hole of the present invention, the fixed pin on the motor shaft snaps into the groove at the upper end of the circular tube, and the motor shaft end is fixed with a round nut to fix the present invention. During work, the motor shaft drives the blades to rotate together with the present invention.

[0026] The rotating impeller generates negative pressure, and under the action of negative pressure, the oil fume enters the air chamber along the axial direction, and hits the horizontal high-speed rotating filter plate vertically. Due to the large radial size and large area of ​​the filter plate, the number of soot particles that collide per unit time is large. The ...

Abstract

The invention relates to a rotary oil smoke filter which can effectively purify oil smoke in an oil smoke gas and has the characteristics of simple and easy operation, and low cost. A plurality of disk-shaped or helical filter plates which have large radial dimensions, good thermal conductivity and fast heat radiation and are prepared from oil smoke adsorption materials are connected in series to form a group, the group transversely rotates at a high speed, cuts the oil smoke, and divides purifying and processing units. So a contact and collision action of oil smoke particles with the filter plates and an oil smoke wall attachment and deposition effect can be enhanced, thereby the oil smoke condensation and deposition effect is improved, and oil smoke filtering and purifying and air cleaning can be realized; and simultaneously cases that a rang hood does not plot oil and accumulate filth, and needs no cleaning can be guaranteed through flinging condensate droplets onto wall surfaces by a centrifugal effect generated through high speed rotation and collecting the droplets. The rotary oil filter has the advantages of simple and easy operation, high efficiency and reliability, good purifying effect and low cost.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a rotary oil fume filter capable of effectively separating oil fume from catering industry, dining halls and family kitchens. Background technique [0002] With the development of cities and the improvement of people's living standards, all kinds of catering industries have developed rapidly, and the accompanying problems of various types of oil fume pollution and nuisance have become important pollution of the urban environment and hot spots of residents' environmental protection complaints. [0003] Oil fume is a kind of aerosol, which is formed by aldehydes, ketones, alkanes, alkenes, polycyclic aromatic hydrocarbons and other components formed by volatilization, oxidation, cracking and hydrolysis of edible oil and food at high temperature and air medium. Dispersion system, the composition is extremely complex; the form includes three phases of gas, liquid and s...
