Abstract

The utility model relates to an air filter belonging to an air grain filter device for solving the problems of the prior air filter device on an air block or large noise due to the likely onflow or resonance. A thin board (1) comprises waves (2) in non-corresponding shapes; a plurality of through holes (3) are provided at the free position of the waves (2); the utility model is used for the lampblack filtering in a kitchen or the waste air filtering in the industry.

Description

The air filtration plate

Technical field:

The utility model is relevant with the device of separating particles from gas.

Background technology:

Existing cooking fume filtering plate is by preceding, and back plate has the interval to connect and compose relatively, and header board has air inlet, and back plate has the gas outlet, and there is the inlet channel that forms turnover between wing plate and the air inlet/outlet at air inlet and edge, gas outlet.Because the wing plate at air inlet/outlet edge is symmetrical, the inlet channel of formation is also symmetrical, and the resistance of relative two passages equates, the two inlet air flow formation surging that meets is total to or resonance, produces vapour lock, rate of discharge is reduced or interruption, work noise is big, and the oil smoke separative efficiency is low.

The device of existing separation oil or fat particles, the a lot of thin slices that are approximate U-shaped by the cross section lay respectively at parallel relative, be separated from each other, two close mutually rows constitute, the thin slice that each row faces with each other forms cavity, the edge of two contiguous sliceses is facing to the cavity of another row's thin slice among one row, and every row's thin slice is made by a thin slice respectively.This device also has the shortcoming of aforementioned cooking fume filtering plate.

The content of utility model:

The purpose of this utility model provides a kind of simple in structure, separation of particles degree height in the air, and noise is little, and is energy-conservation, the air filtration plate that separative efficiency is high.

The utility model is achieved in that

The utility model air filtration plate, thin plate 1 comprise the asymmetric ripple 2 of shape, and some through holes 3 are arranged in the optional position of ripple 2.

The asymmetric ripple of shape is made of radius different long arc and short arc.

The asymmetric ripple of shape is made of raised line 4 and the groove 5 on paralleling to the axis on the thin plate 1, the two side of groove 5 is that the flanging that forms on the thin plate 1 constitutes an angle, and the length of relative two flangings is B, C, and the ultimate range A of two flangings is positioned on thin plate 1 plane, A 〉=B+C, B ≠ C.

Asymmetric wave is divided into the plurality of sections of separation by the plane on the thin plate longitudinal axis.

The surface of thin plate plate 1 is evenly equipped with projection 6 or groove 5.

Through hole 3 is evenly distributed or dislocation arrangement on the longitudinal and transverse axle of thin plate 1.

Connected and composed by two thin plates 1, the passage of last lower thin sheet is relative with the crest inwall of following upper thin sheet at trough, and the two long and short wings of its asymmetric wave form the different gas passage of length respectively relatively.

Ripple of the present utility model is asymmetric shape, phase of wave on two thin plates is right, form two passages of different length and angle in the air admission hole both sides, two different passages that compile above venthole are owing to the resistance difference, and particle collision is met in the increase gas, two inlet air flow of meeting can not form surging or resonance, can not produce vapour lock, runner is unobstructed, and noise is little, the projection of thin sheet surface or groove can increase the contact area of particulate, improve surface adhesion force.The utility model is simple in structure, and is easy to manufacture, with low cost, filters reliably, easy to use, can be widely used in kitchen, dwelling house, working space, public place, the air filtration facility of industrial enterprise.

The specific embodiment:

Embodiment 1:

Vertically be arranged with some raised lines 4 and groove 5 formation ripples 2 on the thin plate 1, raised line 4 is that crest groove 5 is trough.From the cross section of thin slice 1, each ripple 2 is asymmetric trapezoidal, and it is groove 5 that trapezoidal bottom is spaced apart trough, and groove 5 has passage 3.The two side in groove 5 and hole 3 is to form from thin plate 1 upper hem, and its length is respectively B and C, B ≠ C, and the spacing of two crests is A, A 〉=B+C.The axis of every row's ripple is parallel.

Embodiment 2:

Ripple 2 is become proper alignment or staggered plurality of sections by plane separation on the thin plate 1, and all the other structures are identical with embodiment 1.

Embodiment 3:

The structure of two thin plates 1 is with embodiment 1, be rectangle, there is being the interval to be connected by bolt 8 and sealing strip 7 all around, the groove 5 of upper thin sheet is following, the groove 5 of lower thin sheet is last, passage 3 is on the groove 5 or be the slit between two flangings that constitute groove 5, air enters behind the Sealed sandwich between two thin plates over against the back side of the raised line of lower thin sheet from the passage 3 of upper thin sheet 1, and be separated into two strands of air-flows by the passage that two flangings form and meet at the back side of the raised line 4 of upper thin sheet 1, because being uneven in length of two flangings, the length of two passages is also inequality, the place of meeting can not form turbulent flow or resonance, can not form vapour lock, air is smooth logical, can not produce work noise.
