Abstract
The utility model discloses a kind of new coal powder filter element for filtration, it mainly include metal mesh sintering strainer and skeleton, it is characterized in that, it is symmetrical from large to small that metal mesh is sintered each layer metal mesh aperture in strainer, solve the problems, such as that filter core is susceptible to plugging in traditional coal dust filter process, extends the cycle of operation；Metal mesh is sintered strainer according to filter core shape, is divided into the identical component of several shapes, is welded using Split assembled, improves filer element strength, and it is not in breakage problem that metal mesh is sintered strainer in the process of running, eliminates system operation hidden danger.
Description
Technical field
The utility model is specifically related to a kind of filter core, in particular to a kind of pulverized-coal filtering filter core.
Background technique
Traditional pulverized-coal filtering element is metal powder sintered strainer, but in use, because coal dust conveying capacity is big, stream
Fast high, each layer aperture of filter screen is same aperture in metal powder sintered strainer, is easily blocked, and causes system resistance to increase, filtering
Effect is poor, ultimately causes strainer fracture, damage, brings hidden danger to the safe and stable operation of system, need to frequently stop replacement；Tradition
Metal mesh sintering strainer only have 1 weld seam, intensity is lower.
Utility model content
The utility model mainly solve the problems, such as it is of the existing technology, using metal mesh sintering strainer substitute metal powder
Be sintered strainer, metal mesh sintering strainer take Split assembled to be welded, metal mesh be sintered strainer in each layer metal mesh aperture by
It is big extremely small symmetrical, direction is flowed to along medium, first layer aperture is maximum, and system resistance is reduced while improving velocity of medium
Power.It is improved above, to provide, a kind of resistance is small, Novel filter cartridge with long service life.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of new coal powder filter element for filtration mainly includes strainer, skeleton.
The strainer is that the metal mesh for forming 5 layers of metal mesh after sintering is sintered strainer.
Further, the metal mesh sintering strainer is divided into the identical component of several shapes, uses according to filter core shape
Split assembled is welded, and increased weld seam is relied on to improve strainer intensity.
Further, the metal mesh is sintered strainer, from the inside to the outside, the 1st layer of 150-200 μm of metal mesh aperture, preferably
160-180 μm, the 2nd layer of 100-160 μm of metal mesh aperture, preferably 120-140 μm, the 3rd layer of 5-10 μm of metal mesh aperture, preferably 6-
8 μm, the 4th layer of 100-160 μm of metal mesh aperture, preferably 120-140 μm, the 5th layer of 150-200 μm of metal mesh aperture, preferably 160-
180μm.Direction is flowed to along medium, first layer aperture is maximum, and velocity of medium can be improved, reduce system resistance.
The skeleton is that porous plate rolls the tubular being welded or taper support structure.
Further, plate material used in the porous plate can be the various solderable materials such as stainless steel, carbon steel, low-alloy steel
Matter, preferably stainless steel, porous plate is with a thickness of 2-8mm, preferably 3-6mm.
Further, the porous plate shape is identical as metal mesh sintering strainer, is fixedly connected by welding manner.
The utility model has the beneficial effects that
1, metal mesh sintering strainer is not in breakage problem in the process of running, eliminates system operation hidden danger.
2, solve the problems, such as that filter core is susceptible to plugging in traditional coal dust filter process, the cycle of operation extended to 24 by 8 months
Month.
3, increased weld seam is relied on to improve filter core antiscour intensity.

Specific embodiment
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
The present invention will be further described for 1, attached drawing 2, attached drawing 3 and embodiment with reference to the accompanying drawing, in order to the same industry
The understanding of technical staff:
Embodiment 1:
As shown in Figure 1, pulverized-coal filtering is tubular with filter core shape, metal mesh sintering strainer 1 is divided into identical group of 4 shapes
Part is formed an entirety, relatively rolls welding manner and increase 3 weld seams after being welded using Split assembled, had under weld seam effect
Effect improves strainer intensity；Strainer 1 is welded is fixed on skeleton 2 for metal mesh sintering.
As shown in Fig. 2, the 1st layer of 170 μm of 3 aperture of metal mesh, the 2nd layer of 130 μm of 4 aperture of metal mesh, the 3rd layer of 5 hole of metal mesh
6 μm of diameter, the 4th layer of 130 μm of 6 aperture of metal mesh, the 5th layer of 170 μm of 7 aperture of metal mesh；1st layer of metal mesh 3, the 2nd layer of metal mesh 4,
3rd layer of metal mesh 5, the 4th layer of metal mesh 6, the 5th layer of metal mesh 7 form metal mesh sintering strainer after sintering.
As shown in figure 3, porous plate 8 is welded through rolling, material is stainless steel, with a thickness of 3mm, is sintered and filters with metal mesh
Net 1 is fixedly connected by welding manner.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
