Description
Technical field
The utility model belongs to industrial dedusting pipe-line equipment, particularly relates to a kind of iron content dirt gas dedusting magnetic wear-resistant bend.
Background technique
Metallurgy industry dust pelletizing system pipeline there is a large amount of elbow, a large amount of iron dirt is swept along in flue dust air-flow, the long-time high-speed punching brush cleaning shaft of the air-flow of iron content dirt, especially at the bend part of cleaning shaft, in the face of air-flow is thinning to elbow interior wall meeting under the washing away of iron content dirt air-flow of position, mill leaks, breakage, finally cause that dust pelletizing system is leaked out, dust removing effects weakens, maintenance cost and maintenance workload are very large.
Summary of the invention
The purpose of this utility model is the technological scheme proposing a kind of iron content dirt gas dedusting magnetic wear-resistant bend, improves the working life of cleaning shaft elbow.
To achieve these goals, the technical solution of the utility model is: a kind of iron content dirt gas dedusting magnetic wear-resistant bend, comprises channel bend; Protection ferromagnet is provided with away from the external diameter surface of flexural center half cycle at described channel bend.
Further, described protection ferromagnet is the multiple magnet block being arranged on outer diameter tube surface.
Further, described magnet block is permanent-magnet or electromagnet.
Further, be provided with magnet bag at described channel bend away from the external diameter surface of flexural center half cycle, form cavity at the external diameter of described magnet bag and channel bend, described protection ferromagnet is filled in the magnetic particles in described cavity.
The beneficial effects of the utility model are: structure is simple, easy to install; Make the iron dirt in flue gas be adsorbed on inner-walls of duct by magnetive attraction, form protective layer, prevent the erosive wear of channel bend, protective conduit elbow; Improve channel bend working life, reduce maintenance cost.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural drawing that the utility model adopts magnet block;
Fig. 2 is the structural drawing that the utility model adopts magnet bag.
Embodiment
A kind of iron content dirt gas dedusting magnetic wear-resistant bend, comprises channel bend; Protection ferromagnet is provided with away from the external diameter surface of flexural center half cycle at described channel bend.
Embodiment one:
As Fig. 1, a kind of iron content dirt gas dedusting magnetic wear-resistant bend, comprise channel bend 10, channel bend is steel elbow, is provided with protection ferromagnet at described channel bend away from the external diameter surface of flexural center half cycle.
Described protection ferromagnet is the multiple magnet block 20 being arranged on outer diameter tube surface.Described magnet block is permanent-magnet.Magnet block is tile fragment shape, magnet block with the magnetic-adsorption of self at the external diameter surface of channel bend away from flexural center half cycle.
In conveying containing in irony dirt gas process, in dirt gas, irony grit is adsorbed on the inwall of elbow windward side by the magnet block on channel bend, elbow interior wall windward side can form one deck iron powder layer, when fume gases enters elbow, dirt gas can impact dust layer, reduce and rub with channel bend body contacts, thus, prevent iron dust containing from washing away elbow and cause elbow to be worn thinning, damage.
The tile fragment shape permanent magnet made in advance during the protection ferromagnet of the present embodiment, only need be attached to tile fragment shape permanent magnet on channel bend when mounted.After pipeline is abandoned or is removed, protection ferromagnet can be taken off, continue to be used on other channel bends.
The present embodiment onsite application is effective, and maintenance is little, and eliminate elbow on cleaning shaft and, often by mill leakage, air leakage phenomena, decrease elbow spare parts consumption and change elbow construction operation, abridged edition consumption reduction, reduces equipment operating cost.
Embodiment two:
The present embodiment is the improvement of a kind of iron content dirt gas dedusting magnetic wear-resistant bend described in embodiment one.
Described magnet block is electromagnet.
Adopt electromagnet can control the ferromagnetic magnetism intensity of described protection, be applicable to large scale pipeline system, or in experimental system acquiring technology parameter.
Embodiment three:
As Fig. 2, a kind of iron content dirt gas dedusting magnetic wear-resistant bend, comprises channel bend 10, is provided with protection ferromagnet at described channel bend away from the external diameter surface of flexural center half cycle.
Be provided with magnet bag 30 at described channel bend away from the external diameter surface of flexural center half cycle, form cavity at the external diameter of described magnet bag and channel bend, described protection ferromagnet is the magnetic particles 40 be filled in described cavity.
The magnet bag of the present embodiment is welded on channel bend.
Magnetic particles in the present embodiment can adopt the permanent-magnet of various shape, and as granulated, sheet shape, annular etc., magnet material source is wide, strong adaptability, can adopt the magnet material that other equipment and other industry are eliminated, discarded, reduce equipment cost.Be more suitable for the cleaning shaft elbow of Large Diameter Pipeline.
