A washing separation method used for combined multifuncltional equipment includes preparing raw coal, product conveying, removing medium and water, baking, screening, binning and coal slurry processing and recovering, and features that its all steps except the preparing raw coal are performed in conveying route. Its advantages are less investment and low cost for running.
Description
The invention belongs to coal, metal and nonmetallic ore washing technical field, specifically is a kind of being used for and dense media, jigging, spiral, the matching used multi-functional combination accessory washing appliance of the various washing methods of dry method.
Public coal (ore in sand form) washing process is divided into four major parts substantially, and (one) raw coal is prepared, (two) mainly wash, (three) product de-media, dehydration, classification, oven dry (selecting one or more as required), (four) medium, water, coal slime reclaim.It is with raw coal (ore in sand form) screening that raw material is prepared, and meets main washer and goes into to wash the material of granularity and transport main washer to and go into grain mouthful, is not inconsistent to be incorporated into the material of washing granularity and to transport other place to and handle or store.As wash thermal coal, and the above lump coal of 13mm goes into to wash, and the following not coal of 13mm does not go into to wash.
Existing raw coal preparation machine is not by the raw coal travelling belt of simple function, vibratory sieve, 5-6 kind equipment such as coal belt conveyer, lump coal belt conveyer and solid coal separation building just can enter main washer and coal bunker not.Main washer is the nucleus equipment of coal washery.The material that main washer is discharged will carry out de-mediated, dehydration, grading or oven dry to be handled, and the material of discharging from main washer needs just can enter coal bunker through de-mediated dewatering screen, vibratory sieve, many of each grade belt conveyers.Above-mentioned washing system has that equipment is huge, structures requirement height, floor space are big, and the long investment of construction period is big, operating cost height, Operation and Maintenance complexity, shortcomings such as fault rate height.
In addition, the application number that Chinese patent also discloses applicant's invention is 97117073,97228271,97,228,270 3 patents, but this three patents use respectively in occasion separately, does not bring into play the effect of combination function as yet.
The objective of the invention is to have designed a kind of main washer, medium, water, coal slime, middle coal, spoil that keeps in traditional typical process and handle the binning system at above-mentioned drawback, raw coal prepared and product is washed the de-mediated of back processing treatment process, dehydration, oven dry, classification, transportation etc. and used equipment for combined multifunctional once to finish in transportation, the equipment for combined multifunctional washing separation process and the equipment thereof of minimizing equipment investment and floor space.
The present invention realizes like this, multi-functional combination accessory washing method, comprise the raw coal preparation, main washer, Product transport, de-mediated dehydration, oven dry screening, binning and black water are handled and are reclaimed, it is characterized in that: 1, raw coal is prepared to divide combination equipment with raw coal classification in transit by Transporting screen, and the raw coal of feed particle size enters in the washing appliance, and the Transporting screen that is transported to of not going into to wash granularity divides the below of combination equipment to put in storage; 2, the product after the washing is discharged from the discharge gate of washing appliance, fall on the de-mediated dehydration part on the Product transport de-mediated dewatered drying sieve classification unit equipment, enter de-mediated dewatering period, oven dry section, sieve classification section respectively along transporting direction, enter medium bucket, rare medium reclaim line, water reclaim line and grading storehouse that every section below is provided with then respectively.It is to return the chain scraper plate by this machine undersize material is collected to be transported to the warehouse top position and to open up material and mouthful discharge that the raw coal Transporting screen divides the binning function of combination equipment and Product transport de-mediated dewatered drying sieve classification unit equipment, and deadweight falls in the storehouse.
The present invention finishes the combination accessory washing appliance of said method, comprise raw coal Transporting screen subset, main washer, Product transport, the de-mediated dehydration, oven dry sieve classification device, it is characterized in that Transporting screen divides the combination equipment frame in the below of run coal bin, the top of main washer, Transporting screen divides combination equipment to go into to wash the material outlet and is connected with the main washer charging aperture, Product transport de-mediated dewatered drying sieve classification unit equipment frame is in main washer discharge gate below, one end of de-mediated dehydration part links to each other with the discharge gate of main washer, the other end links to each other with Product transport de-mediated dewatered drying sieve classification unit equipment de-mediated dewatering period, and the lower end of each section of Product transport de-mediated dewatered drying sieve classification unit equipment is respectively arranged with the qualified medium retracting device, rare medium reclaim line, the water reclaim line, the graded product storehouse.
The top of the dehydration de-mediated device of the Product transport de-mediated dewatered drying sieve classification unit equipment of multi-functional combination accessory washing appliance of the present invention is provided with water jet, water jet is contained in and takes off rare Jie's section top, remaining medium on the cleaned coal material after the de-mediated first time is swept away, then flow into rare Jie's reclaim line from the below.
On the Product transport de-mediated dewatered drying sieve classification unit equipment oven dry section of multi-functional combination accessory washing appliance of the present invention drying unit is housed, drying unit is that enclosed cavity and shoe have heat-insulation layer, the enclosed cavity below is provided with hot-blast stove, and communicate with the enclosed cavity air inlet, air-introduced machine communicates with the air-flow outlet of enclosed cavity.
The dehydration de-mediated parts of dehydration de-mediated device of the present invention are arc comb sieve or linear comb sieve.The two can select to use and mounting means according to the washing material variety.
The present invention is based on transportation, finishes classification, the binning of raw coal in transportation, product de-media, dehydration, oven dry, screening, binning.According to the use of can arranging in pairs or groups arbitrarily of different coals, the above-mentioned operation of different coal washing methods.
The present invention compared with prior art has the following advantages:
1, device therefor of the present invention is few, and power consumption is few, and personnel selection is few, and structures are simple relatively, takes up an area of and lacks, and therefore, construction investment, duration, operating cost are saved 30-60% than similar prior art design.
2, production system of the present invention is simple, and the unit technology content is lower, and the workman operates, safeguards that fault rate is extremely low easily.
3, the online in process of production oven dry of cleaned coal can guarantee that product moisture content is stable, but also ordinary production when environment temperature is low.
4, the former reason of material sieving technology vibration bulk material changes loose, the device fabrication of rolling into and not restricted by vibration factor, can normally sieve very large amount (less than 3000t/h), humidity (moisture content is greater than 7%), thin (granularity is less than 4mm) coal, solve the construction of super-huge coal washery and wet a duff material sieving technology difficult problem.
