Description
Technical field
The utility model relates to a kind of filter, specifically, relates to a kind of waste gas filter.
Background technology
In prior art, for the filter of scavenging, generally include housing and filter, one end of housing is provided with air inlet, and the other end of housing is provided with gas outlet.Filter is fixed in the inner chamber of housing, and filter is provided with through hole, and aperture is 1mm left and right.By filter is set, carry out the solid impurity in filtering exhaust.Although the filter of this structure can impurity screening, filter effect is not good.A filter is set, and the through hole on filter arranges when excessive, and the impurity that particle diameter is less can not be filtered, and the through hole on filter arranges when too small, and the impurity that particle diameter is larger easily stops up the through hole on filter.
Summary of the invention
technical problem:technical problem to be solved in the utility model is: a kind of waste gas filter is provided, and this filter is the impurity in filtering exhaust stage by stage, and effectively removal of contamination, and impurity can not be gathered on screen pack, stops up mesh.
technical scheme:for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
, this filter comprises housing, the first screen pack and the second screen pack that is provided with cavity, and one end of described housing is provided with air inlet, and the other end of housing is provided with gas outlet; The first screen pack and the second screen pack are parallel to each other, and the first screen pack is fixedly connected with the inwall of housing respectively with the second screen pack, and the first screen pack is between the air inlet and the second screen pack of housing; Angle between the first screen pack and the axis of housing be 30-60 degree, and the first screen pack top than the first screen pack bottom the air inlet near housing; The mesh aperture of the first screen pack is greater than the mesh aperture of the second screen pack.
Further, the mesh aperture of the first described screen pack is 0.5 mm-1mm, and the mesh aperture of the second screen pack is 0.08mm-0.3mm.
Further, the first described screen pack and the angle between the axis of housing are 45 degree.
beneficial effect:compared with prior art, the utlity model has following advantage:
(1) can effectively remove solid impurity.Waste gas filter of the present utility model comprises housing, the first screen pack and the second screen pack.In this waste gas filter, be provided with twice screen pack, and the mesh aperture of the first screen pack is greater than the mesh aperture of the second screen pack.Like this, utilize the first screen pack to filter the larger impurity of particle diameter, then utilize the second screen pack to filter the less impurity of particle diameter.By twice screen pack is set, filter stage by stage the different impurity of particle diameter, filter of the present utility model is the solid impurity in scavenging effectively.
(2) on screen pack, can not gather impurity, the through hole in screen pack is unobstructed.The first screen pack arranging in waste gas filter of the present utility model and the angle between the axis of housing be 30-60 degree, and the first screen pack top than the first screen pack bottom the air inlet near housing.Like this, the accumulation of impurities of the through hole of the first screen pack interception is around through hole, and when gathering to a certain degree, impurity falls into the bottom of housing in the effect of self gravitation, can not be gathered in for a long time around through hole, stops up through hole.In like manner, in the second screen pack, the accumulation of impurities of through hole interception to a certain extent time, also can fall in the effect of self gravitation the bottom of housing.The first screen pack and the second screen pack tilt to lay, and are conducive to impurity, avoid impurity to stop up the through hole on the first screen pack and the second screen pack.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, have: housing 1, cavity 101, air inlet 102, gas outlet 103, the first screen pack 2, the second screen pack 3.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of waste gas filter of the present utility model comprises housing 1, the first screen pack 2 and the second screen pack 3 that is provided with cavity 101.One end of housing 1 is provided with air inlet 102, and the other end of housing 1 is provided with gas outlet 103.The first screen pack 2 and the second screen pack 3 are parallel to each other.The first screen pack 2 is fixedly connected with the inwall of housing 1 respectively with the second screen pack 3.The first screen pack 2 is between the air inlet 102 and the second screen pack 3 of housing 1.Angle between the first screen pack 2 and the axis of housing 1 is 30-60 degree.As preferably, the angle between the first screen pack 2 and the axis of housing 1 is 45 degree.The first screen pack 2 tops are the air inlet 102 near housing 1 than the first screen pack 2 bottoms.The mesh aperture of the first screen pack 2 is greater than the mesh aperture of the second screen pack 3.As preferably, the mesh aperture of the first described screen pack 2 is 0.5mm-1mm, for example, can be 0.5mm, 0.6mm, 0.8mm, or 1mm.The mesh aperture of the second screen pack 3 is 0.08mm-0.3mm, for example, can be 0.08mm, 0.1mm, 0.2mm, or 0.3mm.
Use the waste gas filter of this structure, waste gas enters the cavity 101 of waste gas filter from the air inlet 102 of housing 1, and when waste gas passes through the first screen pack 2, the impurity that in waste gas, particle diameter is larger is tackled by the mesh of the first screen pack 2, can not continue with exhaust-gas flow.Waste gas through the first screen pack 2 continues to flow to the gas outlet 103 of housing 1.The impurity that in waste gas, particle diameter is less is tackled by the mesh of the second screen pack 3.Like this, through twice processing, the impurity in waste gas can be removed substantially.Like this, substantially the waste gas that does not contain solid impurity just flows out from the gas outlet 103 of housing 1.By this waste gas filter is set, can lay the groundwork for the pernicious gas in follow-up scavenging.
Meanwhile, the first screen pack 2 arranging in the waste gas filter of this structure and the angle between the axis of housing 1 are 30-60 degree.The first screen pack 2 and the second screen pack 3 all tilt to lay.The first screen pack 2 tops are the air inlet 102 near housing 1 than the first screen pack 2 bottoms.Like this, the accumulation of impurities of the through hole of the first screen pack 2 interception is around through hole, and when gathering to a certain degree, impurity falls into the bottom of housing 1 in the effect of self gravitation, can not be gathered in for a long time around through hole, stops up through hole.In like manner, in the second screen pack 3, the accumulation of impurities of through hole interception to a certain extent time, also can fall in the effect of self gravitation the bottom of housing 1.The first screen pack 2 and the second screen pack 3 tilt to lay, and are conducive to impurity, avoid impurity to stop up the through hole on the first screen pack 2 and the second screen pack 3.
