Front-end air inlet device for treating lampblack

Abstract

The invention discloses a front-end air inlet device for treating lampblack. The front-end air inlet device comprises a casing and an air inlet cover, wherein an opening A is formed in one side of thecasing; the air inlet cover is arranged at the opening A of the casing; a fan just opposite to the opening A is arranged in the casing; an exhaust opening is formed in one side, away from the openingA, of the casing; two sides of the fan are movably connected with the casing through damping devices arranged on the inner wall of the casing; each damping device consists of a connecting rod which is fixedly connected with the fan and a damping cylinder fixed on the inner wall of the casing; one end, away from the fan, of each connecting rod, is inserted into the corresponding damping cylinder and does reciprocating motion in the corresponding damping cylinder along the axial direction; a circular separation blade perpendicular to each connecting rod is arranged at the end part of the inserting end of the connecting rod; the curved side wall of each circular separation blade makes contact with the inner wall of the corresponding damping cylinder; springs fixed on the inner walls of the damping cylinders are respectively arranged on the surfaces of the upper and lower sides of the circular separation blades; a buffer force is provided for reciprocating motion of the connecting rods bythe springs arranged on the upper and lower sides of the circular separation blades. The front-end air inlet device disclosed by the invention is simple in structure and capable of reducing noise.

Description

technical field [0001] The invention relates to the field of oil fume treatment equipment, and specifically refers to a front-end air intake device for oil fume treatment. Background technique [0002] Kitchen fume is a large amount of thermal oxidation decomposition products produced by cooking oil and food under high temperature conditions. When cooking, the fat is heated. When the temperature reaches the smoking point of edible oil at 170°C, the blue smoke of initial decomposition appears. As the temperature continues to rise, the decomposition speed accelerates. There is a pungent smell, and the particle size of oil fume is 0.01-0.3 microns. The oil fume samples collected from households that often fry food were analyzed, and a total of more than 220 chemical substances were detected, including aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones, heterocyclic compounds, etc. . Known mutational carcinogens such as volatile nitr...
