Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the utility model provides a kind of sieve, broken integral intelligent treatment system, for power station coal being carried out sieve, broken, transport and store, make raw coal 100% meet station boiler and run needs.This treatment system is mainly divided into Feedstock treating part, transport portion, storage area three parts, and used structure comprises feeding mechanism, main screening roller picker 4, belt conveyor 5, primary breakup device 6, final stage breaker 7, latter end screening roller picker 8, feeder trough 9 and coal bunker 10.
Described feeding mechanism is for realizing the charging of coal raw material, and it comprises feed hopper 1, and is arranged between feed hopper 1 and main screening roller picker 4, for carrying out the charging roller picker 3 of discharging to coal raw material.Further, for coordinating the discharging of charging roller picker 3, grid sieve 2 in the charging aperture of described feed hopper 1, is also provided with.
Described main screening roller picker 4 is for carrying out elementary screening and uniform distribution to coal raw material, granularity is greater than sieve seam and be less than sieve seam material screening out, it comprises connection successively and is the inclination roller picker section of unshrouded impeller chi structure, the first circular arc roller picker section and the second circular arc roller picker section, wherein, inclination roller picker section is connected with feeding mechanism, and the second circular arc roller picker Duan Zeyu latter end screening roller picker 8 connects.In the present embodiment, main screening roller picker 4 is roller picker with charging roller picker 3, and only compass screen surface angle is different for the two, and charging roller picker 3 roller vane is less, band dentation, design 3-4 level roller bearing, and angle is mild; And main screening roller picker 4 angular slope.
Described primary breakup device 6 carries out coarse crushing for material granularity being greater than to sieve seam, and continues screening by the material after the 3 pairs of coarse crushings of main screening roller picker.Primary breakup device 6 mainly carries out coarse crushing to bulk materials, and therefore, in the present embodiment, primary breakup device 6 selects ring to hammer crusher rotor into shape, and the ratio of reduction is large, crosses Fragmentation Phenomena few.Described final stage breaker 7 is then for carrying out in small, broken bits to the material after coarse crushing, and in the present embodiment, rotor of hammer type crusher selected by final stage breaker 7, adopts hammer crushing mode, can ensure the granularity of material.
Described latter end screening roller picker 8 is for sieving the material after in small, broken bits, and the material making granularity be greater than sieve seam drops in feeder trough 9, is then stored by feeder trough 9, and is returned to by material in feed hopper 1.The material that granularity is less than sieve seam then all drops in belt conveyor 5, stored in mass transport to coal bunker 10 by this belt conveyor 5, be provided with coal amount upper and lower limit in described coal bunker 10 and control sensor, and be connected to control centre, realize the monitoring to coal bunker 10 memory space.
Based on said structure, below the utility model is sieved coal raw material, tear reason process be introduced.
First, entered via feed hopper 1 by coal raw material, first grid sieve 2 carries out Preliminary screening to coal raw material.Material after screening drops in charging roller picker 3 and carries out discharging.Charging roller picker 3 can start according to the flow of material in good time and stop, and prevents bulk materials from blocking feed hopper 1, and plays the effect of auxiliary cloth.
Material after discharging is dynamic mobile by main screening roller picker 4 medium dip roller picker length of tape, wherein, the material (qualified material) that granularity is less than main screening roller picker sieve seam drops in the belt conveyor 5 of below naturally, and granularity is greater than the material that sieve stitches and is then fed through in primary breakup device 6 by main screening roller picker 4 and carries out coarse crushing.
After coarse crushing, qualified material drops in belt conveyor 5 equally naturally, and the material that granularity is still greater than sieve seam is then continued to be fed into in final stage breaker 7 by the first circular arc roller picker section in main screening roller picker 4.Final stage breaker 7 carries out in small, broken bits to the material sent into, material after in small, broken bits is through the second circular arc roller picker section and twice screening of latter end screening roller picker 8, qualified material drops in belt conveyor 5 equally naturally, the last material still exceeded standard then sieves roller picker 8 by latter end and is sent in feeder trough 9, and then be back to feed hopper 1, and continue the above-mentioned processing procedure of circulation, ensure that the material after via the process of the utility model system has the qualification rate of 100%.
While above-mentioned screening and broken material, qualified material also continues to be fed through in coal bunker 10 and stores by belt conveyor 5.Further, main screening roller picker 4, in the process of whole screening materials carrying, utilizes the principle of adjacent roller bearing differential, also can to realize around each roller bearing 360 ° without dead angle self-cleaning, material is not occurred sticky stifled in the process of fragmentation.
In addition, drop in the process of belt conveyor 5 at material, owing to can produce certain dust, therefore, the utility model is also provided with dedusting fan 11 on latter end screening roller picker 8 side, for absorbing dust, keeps environment clean and tidy.
The utility model have devised a kind of intelligentized treatment system for power station coal raw material, the one automation mechanized operation achieving coal material screening, fragmentation well and carry, while guarantee material 100% qualification rate, drastically increase the efficiency of work, save a large amount of man power and material's costs.Therefore, compared to existing technology, technological progress is obvious, and it has substantial feature and progress for the utility model.
Above-described embodiment is only preferred embodiment of the present utility model; should not be used for limiting protection domain of the present utility model; all in this basis and the change carried out technical solutions of the utility model mentally or polishing; the problem that its essence solves is still consistent with the utility model, all should be included within protection domain of the present utility model.
