Abstract
The utility model relates to a dust filter which is a barrel body on which an arc-shaped annular groove is arranged radially on an outer surface made of a metal sintered net. The outer surface of the barrel body is of an arc transition; the upper end of the arc transition is fixedly provided with a flange, and the upper part of the flange is provided with a convex rim; the lower end is fixedly provided with a stopper matched with the barrel body. The dust filter has high filtration efficiency, can eliminate the static electricity of materials and has a long service life.
Description
Technical field
The utility model relates to a kind of dust filter unit.
Background technology
Dust filter unit is applied on the conveying equipment of powder, granular material, is used for efficient separation of material and air.At present, dust filter unit is adopted nonwoven or macromolecular material both at home and abroad more, make the filter of difformity, different structure.Nonwoven is damaged easily and fall fiber, and fiber is infiltrated in the material, has a strong impact on the cleanliness factor of material, and pore size filter is bigger, the anti-clogging poor-performing; Its life-span is short, often changes the efficient that influence is produced.Macromolecular material such as plastic filter are easy to generate static, not only change the physical features of material, even produce blast, seriously influence production safety.
The utility model content
The purpose of this utility model is to improve the shortcoming of prior art and a kind of filter efficiency height is provided, can eliminates the dust filter unit of material static, long service life.
For achieving the above object, the utility model has been taked following technical scheme:
A kind of dust filter unit, it is the cylindrical shell that an outer surface made from the metal sintering net radially is provided with arc-shaped ring groove, and described barrel outer surface is an arc transition, and its upper end fixedly installs a flange, and described flange top is provided with a convex edge; The lower end fixedly install one with the plug of staving coupling.
The utility model compared with prior art has the following advantages:
1, the utility model is made by the metal sintering net, and is simple in structure, and the situation because of the breakage contaminated material can not appear in intensity height easily; Because of being beneficial to, its conduction eliminates material static, long service life again.
2, slick and sly no dead angle, the utility model surface, the aperture is even, can prevent material bonding, plug, folder in the use, the material blockage problem can not take place.
3, the utility model surface is designed for arc, and volume is little, but has bigger filter area under the space that is equal to, and efficient is higher.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is the A-A cutaway view among Fig. 1.
The specific embodiment
Shown in Fig. 1-4, a kind of dust filter unit described in the utility model, it is the staving 1 that an outer surface made from stainless steel sintering net radially is provided with 5 arc-shaped ring grooves, and described barrel outer surface is an arc transition, and cross section is quincuncial, as shown in Figure 4.
The upper end of described staving 1 fixedly installs the flange 2 that a top is provided with convex edge 21, during installation, dust filter unit is connected with external equipment by flange 2, and can between flange and external equipment, be provided with axially and/or seal radially, good airproof performance, thereby the particulate dust that filters can not overflowed from the outside of filter, all will pass through filter, and filter effect is better.
The lower end fixedly install one with the quincunx plug 3 of staving coupling.
During use, the gas in the dust air-flow enters staving 1 inside from the stainless steel sintering net of this dust filter unit, and is drawn out of from suitable for reading, and dust is separated in outside the sidewall by the stainless steel sintering net of dust filter unit.
The utility model difference from Example 1 is, it is one and makes with titanium sintering net.Its anti-clogging better effects if, regeneration is easy, and regeneration times is quite high.
Claims (1)
1, a kind of dust filter unit is characterized in that, it is the cylindrical shell that an outer surface made from the metal sintering net radially is provided with arc-shaped ring groove, and described barrel outer surface is an arc transition, and its upper end fixedly installs a flange, and described flange top is provided with a convex edge; The lower end fixedly install one with the plug of staving coupling.
