Abstract
The invention relates to an automatic separator of sundries contained in raw coal, comprising a rack and a shell, wherein the shell is internally provided with a rotating shaft erected on the rack; the rotating shaft is distributed with tines and an archimedes spiral stripping plate which is fixed on the rack and provided and is symmetrical upper and lower is arranged corresponding to the tines; the archimedes spiral stripping plate is provided with tine gaps, and the tines are correspondingly arranged in the tine gaps; the tine is sleeved with a slide block; the slide block is provided with an upper idler wheel and a lower idler wheel; and the archimedes spiral stripping plate is arranged between the upper idler wheel and the lower idler wheel and is provided with a raw coal inlet corresponding to the upper part of an inner cavity of the shell, a raw coal outlet on the lower part and a sundries outlet corresponding to the tail end of the arc-shaped stripping plate. The invention can remove soft sundries contained in the raw coal, ensure the safety supply of coal and is used for the sundries remove of granular materials in industries, i.e. thermal power (heat) generation, coal mines, raw coal application, ports, wharfs, metallurgy, building materials, and the like.
Description
Technical field
The present invention relates to a kind of automatic separator of sundries contained in raw coal, be used for the removal of impurities that firepower is sent out the granule materials of industries such as (heat) electricity, colliery, raw coal application, port and pier, metallurgy, building materials.
Background technology
Send out at firepower (heat), the colliery, raw coal is used, port and pier, metallurgical, in the industries such as building materials, many times, granule materials needs removal of impurities, in thermal power generation corporations, owing to multiple reason, raw coal is being produced, transportation, sneak into many foreign material in storage and the use, be doped with the big gun line more, rag, the rope made of hemp, fiber, weeds, soft waste articles such as plastics, cause belt feeder and run coal bin feed opening to stop up easily, especially severe be in follow-up powder manufacturing apparatus, can cause separator blocked, can't guarantee to supply the evenly unimpeded of powder, need often clear up, not only take a lot of work, and influence the safe and stable operation of boiler.
Summary of the invention
The object of the present invention is to provide a kind of automatic separator of sundries contained in raw coal, can remove the soft waste articles in the raw coal, guarantee security provisions with coal.
Automatic separator of sundries contained in raw coal of the present invention, organic frame and shell, rotating shaft on the frame of being erected at is arranged in the shell, be distributed with moving tooth in the rotating shaft, corresponding moving tooth is provided with the peel plate that is fixed on the laterally zygomorphic spiral of Archimedes shape on the frame, peel plate is provided with the moving tooth gap, the moving tooth correspondence places the moving tooth gap, be set with slide block on the moving tooth, bottom roller is installed on the slide block, and peel plate places between the bottom roller, and corresponding housing inner chamber top is provided with raw coal inlet, the bottom is provided with former coal export, and the end of corresponding arc peel plate is provided with miscellaneous object outlet.
In the application, raw coal enters the shell inner cavity from raw coal inlet, and rotating shaft drives moving tooth and rotates, and moving tooth is provoked the soft waste articles that mixes in the raw coal and concentrated attached on the moving tooth, and peel plate causes miscellaneous object outlet by slide block with the soft waste articles on the moving tooth, obtains separating.Last bottom roller helps slide block and moves along peel plate.
Among the present invention:
The raw coal belt conveyor is established in corresponding raw coal inlet, is used for direct coal supply.
Corresponding miscellaneous object outlet is joined glove compartment (also can be foreign material and handle chute), is used for the soft waste articles that centralized collection is picked out.
Critical piece adopts precision casting technology, and track, wheel bar, pulley etc. are selected high-abrasive materials such as stainless steel for use, and working stability is reliable, and working stability is reliable, and maintenance capacity is little.Equipment dynamic adopts frequency conversion control technique, can adjust gear teeth parts operating rate arbitrarily according to the raw coal flow.
Above former coal export, establish the obstruction detection components,, can detect former coal export immediately and whether stop up as swiveling wheel and electronic probe, according to jam signal, by implementing DCS configuration and telecommunication, the supply of raw coal is handled in control, so that in time cleaning is stopped up, and is more safe and reliable.
The present invention is simple in structure, can well the soft waste articles in the raw coal be picked out, and has purified raw coal, in thermal power generation, avoided the blocked phenomenon of separator in the follow-up powder manufacturing apparatus, guaranteed to supply the evenly unimpeded of powder, made the safe and stable operation of boiler obtain guarantee.Be widely used in the removal of impurities of the granule materials of industries such as colliery, raw coal application, port and pier, metallurgy, building materials, regulate the spacing of moving tooth, removal of impurities with the particulate material that adapts to the variable grain size is handled, form a plurality of model types, adapting to the raw coal particle diameter is the particulate material of 30-150mm, and disposal ability is 100-3500t/h.Can use by plural serial stage, the pure rate of soft waste articles separating treatment can reach more than 95%.

The specific embodiment
The invention will be further described in conjunction with the foregoing description accompanying drawing.
As shown in the figure, automatic separator of sundries contained in raw coal of the present invention, organic frame 8 and shell 3, rotating shaft 5 on frame of being erected at 8 is arranged in the shell 3, be distributed with moving tooth 4 in the rotating shaft 5, corresponding moving tooth 4 is provided with the peel plate 6 that is fixed on the laterally zygomorphic spiral of Archimedes shape on the frame, peel plate 6 is provided with the moving tooth gap, moving tooth 4 correspondences place the moving tooth gap, are set with slide block 12 on the moving tooth 4, on the slide block 12 bottom roller are installed, peel plate 6 places between the bottom roller, corresponding housing inner chamber top is provided with raw coal inlet 2, and corresponding raw coal inlet 2 is provided with belt conveyor 1, is used for directly supplying raw coal, the bottom is provided with former coal export 10, the end of the peel plate of corresponding arc is provided with miscellaneous object outlet 7, and corresponding miscellaneous object outlet 7 is furnished with glove compartment 9, is used for the soft waste articles that centralized collection is picked out.
During use, by belt conveyor 1 raw coal is delivered directly to raw coal inlet 2, enter the inner chamber of shell 3 from raw coal inlet 2, rotating shaft 5 drives moving tooth 4 and rotates, moving tooth 4 is provoked the soft waste articles that mixes in the raw coal and is concentrated attached on the moving tooth 4, the peel plate 6 of arc moves by moving ahead of slide block 12 and moving up and down on the moving tooth soft waste articles on the moving tooth 4 is caused miscellaneous object outlet 7, thereby cleared up the winding in moving tooth 4 and the peel plate gap or left over soft waste articles, obtain separating and concentrating and collect in the glove compartment 9, the raw coal after the cleaning removal of impurities is discharged from former coal export 10.
Whether stop up detection components 11, can detect former coal export 10 immediately and stop up, this signal, so that in time cleaning is stopped up, more safe and reliable with control system if can link.
