The existing discharger has the problems that the impeller is directly contacted with materials, the abrasion is easy to occur, and the service life is short, so that the rotary discharger with the wear-resistant impeller is improved and researched, the service life is prolonged by 2-3 times compared with the original rotary discharger, and the application range of the rotary discharger is wider.
SUMMERY OF THE UTILITY MODEL
The problem that there is easy wearing and tearing, life weak point in order to overcome the impeller of present tripper, the utility model provides a wear-resisting impeller of rotatory tripper.
The wear-resistant impeller of the rotary discharger is realized by the following technical scheme:
the wear-resistant impeller of the rotary discharger comprises side plates, a sleeve, scrapers, a hard alloy layer and a transmission shaft, wherein the sleeve is fixedly connected with the transmission shaft and the scrapers respectively, 6-8 scrapers are uniformly welded on the sleeve, the two sides of each scraper are fixedly connected with the side plates respectively, and the outer sides of the scrapers and the incoming material side of each scraper are fixedly connected with the hard alloy layer respectively.
Preferably, the sleeve is fixedly connected with the transmission shaft through a flat key, so that the impeller rotates in the discharger to play a discharging role.
Preferably, the fixed connection mode of the scraper and the side plate is welding and is used for preventing materials from escaping.
Preferably, the outer side of the scraper and the incoming side of the scraper are fixedly connected with the hard alloy layer in a welding mode.
Preferably, the hard alloy of the hard alloy layer includes tungsten-cobalt hard alloy, tungsten-titanium-cobalt hard alloy, and tungsten-titanium-tantalum hard alloy.
Preferably, the side plates, the sleeve, the scraper and the transmission shaft are made of metal, and the metal comprises steel, aluminum alloy, stainless steel and iron.
Preferably, the hardness of the scraper is more than or equal to 50HRC, the hardness of the scraper is 2 times of the hardness of the original scraper, and the service life of the discharging impeller can be greatly prolonged.
Compared with the closest prior art, the utility model provides a technical scheme has following beneficial effect:
1. the hard alloy layer is welded on the outer side of the scraper and one side of the scraper, so that the hardness of the scraper is 2 times of that of the original scraper, the service life of the impeller is prolonged by 2-3 times compared with the original impeller, the overhaul period of the rotary discharger is greatly saved, and the equipment stability is higher.
2. After the scraper blade outside with scrape material one side welding carbide layer, the difficult wearing and tearing in blade outside can carry the higher material of value, can not lead to the material card to change between impeller and casing and by the extrusion result in the material characteristic because of the impeller wearing and tearing back, and the applicable scope of unloading is wider.
