Description

Chain scraper reclaimer

Technical Field

The utility model relates to a reclaimer, concretely relates to chain scraper blade reclaimer.

Background

The chain scraper reclaimer is one large loading and unloading apparatus for efficient continuous operation of bulk material pile and is used mainly in coal and ore storing yard in electric power, metallurgy, coal, building material, chemical industry and other industries. The device mainly comprises a transmission mechanism, a cantilever, an arm frame, a balance beam, a tail vehicle, a pitching mechanism, a walking mechanism, an annular scraper with a chain wheel and the like.

For most bulk materials which do not have requirements on granularity, such as coal, mineral powder and the like, the scraper reclaimer has strong adaptability and high operation efficiency, but for blocky materials and materials which have requirements on granularity, in the scraper reclaiming process, scraping difficulty often occurs, the annular scraper has large running resistance, large equipment running load, increased energy consumption and increased faults, and a series of problems that the blocky materials are easy to break and the like are easily caused in the scraper reclaiming process, so that the application of the scraper reclaimer is limited.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome prior art's defect, the utility model discloses a chain scraper blade reclaimer, this reclaimer can be applied to the high efficiency and scrape and get cubic material and have the material that requires to the granularity, reduce the fault rate and reduce the damage of material.

The technical scheme is as follows: the utility model relates to a chain scraper reclaimer, which comprises a track, a walking frame, a chain scraper device and a telescopic pitching mechanism; the chain scraper device is provided with an annular scraper chain and a plurality of rake scrapers which are distributed around the outer surface of the annular scraper chain at equal intervals; the rake scraper comprises a plate body and a plurality of rakes, wherein the plate body is rectangular, the inner end of the plate body is vertically connected to the outer surface of the annular scraper chain and is arranged along the width direction of the annular scraper chain, and the rakes are arranged at the outer end of the plate body at intervals and protrude outwards from the outer end of the plate body.

Has the advantages that: according to the chain type scraper reclaimer, the scraper for reclaiming is arranged into a structure combining a rectangular plate body and the harrow pins to form a nail harrow type scraper, when blocky materials are scraped, the harrow pins can be inserted into gaps among the material blocks in a material pile so as to separate the piled blocky materials, reduce the damage of the materials, reduce the running resistance of the annular scraper, reduce the energy consumption and reduce the faults; when scraping the material that gets the granularity requirement, through setting up suitable rake nail interval, can tentatively select the material that the granularity meets the requirements, improve the efficiency of getting the material.

fig. 2 is the structural schematic diagram of the rake type scraper of the chain scraper reclaimer of the utility model.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a chain scraper blade reclaimer that uses at C type feed bin 100, and the inside material of stacking of this C type feed bin 100 is the coke, and the material has characteristics such as easy breakage, the coke matter hardness is big, different sources coke granularity component span is big. In order to improve the material taking efficiency and reduce the breakage rate of coke blocks, the chain scraper reclaimer of the embodiment is shown in fig. 1.

The chain type scraper reclaimer comprises a track 1, a walking frame 2, a chain type scraper device 3 and a telescopic pitching mechanism 4. The rail 1 has two guide rails arranged on both sides of the pile 10 and extending in the longitudinal direction of the pile 10. The walking frame 2 stretches over the material pile, the two ends of the walking frame 2 are provided with advancing devices, the two advancing devices are respectively and correspondingly arranged on the two guide rails, and the walking frame 2 moves on the rails 1 through the two advancing devices.

The two ends of the chain type scraper device 3 are respectively a material taking end and a material discharging end, and the material discharging end is hinged on the walking frame 2. And the chain type scraper device 3 is hung on the walking frame 2 through the telescopic pitching mechanism 4. The chain flight device 3 has an endless flight chain 5, and a plurality of rake flights 6 arranged at equal intervals around the outer surface of the endless flight chain 5.

As shown in fig. 2, the rake scraper 6 includes a plate body 61 and a plurality of rake nails 62, which may be integrally formed or made detachable for easy maintenance and replacement. Specifically, in the production of the rake blade 6 of the present embodiment, a 25Mn steel plate having an extremely high wear resistance and a thickness of 8mm is selected, and a rectangular blade having an appropriate size is cut by a special machine tool, and then the upper portion 2/3 of the blade is highly cut to form a plurality of rake nails 62 arranged at intervals, and the plate body 61 portion of the lower portion 1/3 is kept in a rectangular configuration. The width of the rake nails 62 is 8-12mm, and the gap between adjacent rake nails 62 is 40-60 mm. Then, the plate body 61 and the rake nails 62 are ground until the edges and corners are rounded to reduce the friction force, and finally the rake scraper 6 is formed. The width and gap of the brads 62, even the length of the brads, can be properly adjusted according to the properties and granularity composition of the materials to be taken so as to improve the applicability. The inner end of the plate body 61 is perpendicularly connected to the outer surface of the endless blade chain 5 and arranged along the width direction of the endless blade chain 5, with the raker nails 62 projecting outwardly from the outer end of the plate body 61.
