Abstract
Provided is a gas filter with a good filter effect and a high utilization rate of a filter cartridge. The filter cartridge is arranged inside a barrel body. An air inlet and an air outlet are installed on the barrel body. The gas filter is characterized in that the air inlet is located on a portion of the barrel body which is corresponding to one end of the filter cartridge, and the air outlet is located on a portion of the barrel body which is corresponding to the other end of the filter cartridge. The gas filter is applicable for gas filtration.
Description
Technical field
The utility model relates to gas-filtering device, particularly filer element type gas transition.
Background technology
In the past the filer element type pneumatic filter as shown in Figure 3, its air inlet c and gas outlet d be corresponding to filter core a one end, on the radially same rectilinear direction of cylindrical shell b, wherein gas outlet d is inner is connected with filter core a end.Because distance is short between the inlet, outlet, and inlet, outlet is in radially same rectilinear direction, and gas is little to gas outlet pressure constant interval from air inlet, and this interval internal pressure gradient is large, and the cylindrical shell inherence areal pressure relative homeostasis far away apart from inlet, outlet, gas flow is seldom arranged, make this zone be in " building the pressure " state, most of filter core is by " short circuit ", the filter localised load is excessive, gas flow is crossed the speed of filter core, and filter effect is not good enough, and the filter core utilization rate is not high.
Summary of the invention
The utility model will solve to live the filter cartridge type filter filter effect not good enough, and the problem that the filter core utilization rate is not high provides a kind of filter cartridge type filter of the present utility model for this reason, this filter good filtration effect, and the filter core utilization rate is high.
For addressing the above problem, the technical solution adopted in the utility model is to be provided with filter core in cylindrical shell, be connected with air inlet and gas outlet on the cylindrical shell, its special character is that described air inlet is positioned at cylindrical shell corresponding to the position of filter core one end, and described gas outlet is positioned at cylindrical shell corresponding to the position of the filter core other end.
The utility model can be that the position corresponding to described air inlet is provided with buffer board in the described cylindrical shell, and the mainboard face of buffer board is right against air inlet, and an alternate distance with the air inlet inner lip, and described gas outlet is inner to be connected with the filter core end.
The utility model also can be that a described filter core end corresponding with the gas outlet is connected with the filter core pallet, and all bandings of this filter core pallet are connected in described cylinder inboard wall, and cylindrical shell is separated out outlet chamber, and described gas outlet is positioned at outlet chamber.
The utility model is because air inlet and gas outlet correspond respectively to the filter core two ends, gas is present on the whole length direction of filter core at the pressure reduction between the inlet, outlet, so that air-flow enters into filter core inside from the whole surface of filter core, flow out from the gas outlet again, air velocity is relatively slow, so the filter core interest rate is high, good filtration effect; The air inlet corresponding position is provided with the utility model of buffer board, and charge air flow is broken up, and prevents that high velocity air from directly impacting filter core.
