It is connected to shell.The present invention is tubular filter, and filter area is big, and occupied area is small, and air enters from air inlet pipe when filtering
Air chamber, due to the presence of isolating cylinder, air enters in inlet chamber from the bottom opening of isolating cylinder down to be filtered again, can be kept away
Exempt from direct impact of the air to filter medium, so that air is uniform, steadily enters and passes through filter medium, while being conducive to air
In particle sedimentation, avoid blocking filtering medium, filtered air enters porous tubular support and is discharged from outlet side；Porous branch
Stay tube plays the role of skeleton, attachment and package for wire mesh, knitmesh and filter medium, while bearing the pressure on both sides
Difference avoids the deformation of wire mesh, knitmesh and filter medium；Wire mesh and knitmesh enable filter medium uniform stressed；Sealing plate rises
To the effect of baffling, air is radially dispersed air is made to be directly entered inlet chamber, improve filter efficiency；Guide shell plays guiding
Effect, directs the air into inlet chamber, and guide shell is directed at sealing plate, is conducive to the dispersion of air.
Preferably, being equipped with connection flange on the outside of the upper end opening of the shell, set in the porous tubular support outside wall surface
There is connection chimb, is fixedly connected between the connection flange and connection chimb by bolt seal.Connection flange with connect chimb
Between be fixedly connected by bolt seal, it is convenient for disassembly and assembly, for improve sealing effect, connect flange and connection chimb between can put
Set the sealing elements such as gasket.
Preferably, the isolating cylinder is fixed between shell and porous tubular support, the upper end of isolating cylinder with connect chimb
It is fixedly connected.
Preferably, the wire mesh is the copper mesh of 30~40 mesh.
Preferably, the knitmesh is burlap.
Preferably, the filter medium is filter paper.
Preferably, the diameter of the air hole is 5~10mm, the center of air hole is away from for 10~20mm.
Preferably, the sealing plate diameter is greater than open support pipe outside diameter.Sealing plate diameter is greater than porous tubular support, is greater than more
Limit, support are played the role of in the part of hole support tube, avoid the wire mesh being wrapped in outside porous tubular support, knitmesh and filtering
Medium glides.
Preferably, the end face of the housing bottom is set as spherical surface.The end face of housing bottom is set as spherical surface, plays guiding and makees
With entering guide shell convenient for air.
Therefore, it is simple that the invention has the following beneficial effects: structures, stable, and filter area is big, and occupied area is small,
Filter efficiency is good, and filter efficiency is high.
