Abstract
The invention relates to a high temperature wearable material blower made from a high chrome alloy composite material, which belongs to the technical field of power electric appliances, and is characterized in that all the surfaces contacting materials in the material blower are made from high temperature wearable bimetal plates; the joint of an impeller hub and a vane is welded and covered by a wearable layer. The high temperature wearable material blower has the advantages: compared with the prior art, the proposal has good high temperature resistance (500 DEG C), wear resistance and shock resistance, not only solves the problem of the material blower for the pneumatic feeding of hard powder materials under a high temperature condition and satisfies the production requirements on continuous high temperature operation for a long time for the material blower, but also reduces the abrasion, the maintenance cost and the shutdown frequency, prolongs the service life, and greatly improves the economic benefit.
Description
Technical field
The invention belongs to the power technical field of electric appliances, relate to a kind of improvement of mine ventilator.
Background technique
At present, known materiel fan, its impeller, blade, housing, blower fan are imported and exported and the development unit material therefor adopts general steel plate or manganese steel plate to make more, do not have high temperature resistant preferably and wear-resisting property, at workroom in high temperature or wind deliver coal powder, mineral powder class material, in the time of need be than the using scope of high-wear resistance, can't satisfy the requirement of these industrial and minerals.The blower fan that has adopts processing methods such as case-carbonizing, boronising, and the defective of these methods is that wearing layer is too thin, and several millimeters at zero point are only arranged.Methods such as in addition ceramic embedded, alloy, though but can wear-resistant shock resistance during the defective of this several method very poor, above method all exists the phenomenon that resistance to high temperature, wear-resisting property, the shock resistance three that can't satisfy blower fan simultaneously requires.Therefore maintenance and replacing are frequent, and working life is shorter.Can't guarantee the long-time continuous production requirement.
Summary of the invention
The objective of the invention is:
Provide a kind of and make the high-temperature wearable materiel fan with the high-chromium alloy composite material, it is a kind ofly can satisfy high temperature resistantly, can satisfy the particular mine wind conveyer of wear-resisting requirement again.
Technological scheme of the present invention is:
On inner all surfaces that contact with material of materiel fan, all adopt the high-temperature wearable bimetallic plates to make, impeller hub reaches with the blade point of attachment and adopts welding of wear-resisting layers to cover.
Bimetallic plates are by forming for metal substrate and high-chromium alloy plate, and built-up welding one deck high-chromium alloy plate makes it to become composite sheet on substrate, high-chromium alloy plate thickness 1-10 millimeter.
The invention has the beneficial effects as follows:
Compare with technology in the past; this scheme has good temperature resistance energy (500 ℃); wear-resisting property; shock resistance has not only solved materiel fan and has sent the problem of hard granular material in the high-temperature condition leeward, has satisfied the production demand of materiel fan long-time continuous high-temperature operation; and reduce wear; reduce maintenance expenses and shut down frequency, increase the service life, economic benefit improves greatly.
