Example Embodiment

[0018] Example 1:

[0019] A front-end air intake device for oil fume treatment of this embodiment, such as figure 1 As shown, it includes a casing 1 with an opening A on one side and an air intake cover 2 arranged at the opening A of the casing 1. The casing 1 is provided with a fan 3 facing the opening A, and the casing 1 An exhaust port 4 is provided on the side away from the opening A; the two sides of the fan 3 are movably connected with the housing 1 through a shock-absorbing device provided on the inner wall of the housing 1; the shock-absorbing device is fixedly connected to the fan 3 The connecting rod 5 is composed of a shock-absorbing cylinder 6 fixed on the inner wall of the casing 1. The connecting rod 5 is inserted into the shock-absorbing cylinder 6 at one end away from the fan 3 and reciprocating along the axis direction in the shock-absorbing cylinder 6; the connecting rod 5 is inserted One end is provided with a circular baffle 7 perpendicular to the connecting...

Example Embodiment

[0021] Example 3:

[0022] This embodiment is based on the foregoing embodiment and further defines that a metal mesh filter layer 11 for filtering is provided between the opening A and the fan 3 of the housing 1. An oil-proof shell 12 that completely wraps the fan 3 is provided on the outside of the fan 3. A tapered flow deflector 13 is provided on one side of the opening B. A soundproof sponge layer is provided on the outside of the shell 1. The other parts of this embodiment are the same as the foregoing embodiment, and will not be repeated.

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...
