Abstract
The invention discloses a screening and breaking system arrangement technology. According to the technology, a screening device is arranged in a belt conveyor material feeding layer, two discharge channels are used for screening device material discharge, one of the discharge channels is used for conveying screened particles with qualified particle sizes from a material falling pipe to a belt conveyor 3#, the other one of the discharge channels is used for feeding blocked particles with unqualified particle sizes into a breaker and feeding the broken particles into the belt conveyor 3# and the particles from the two channels are merged and fed into the next process through the belt conveyor 3#. The technology solves the problem that a screening machine cannot be arranged because of a deficient breaker spatial size.
Description
Technical field
The present invention relates to a kind of broken building technique, be related specifically to coal, mine, coking field.It is particularly suitable for defeated coal sieving approach building, thermal power plant.
Background technology
The coal gangue particle of firepower coal gangue power generation factory burning in circulating fluid bed boiler certain proportion particle diameter, in the coal charge of colliery, coal charge contains substantial amounts of qualified particle diameter and need not repeat to crush, it is 40-80% that qualified particle size content in coal is carried out in colliery, it is thus desirable to screening machine is separated qualified particle diameter to alleviate crushing, coal grain is allowed to more conform to boiler particle diameter combustion curve.
Existing domestic few part Self-lighting Coal Transportation System is the most all provided without screening machine prescreening, but supplied materials is directly entered disintegrating machine and entirely enters complete broken way.This main cause is caused to be: not have locus that screening machine is installed.

Described 2# screening belt conveyer type of drive uses motorized pulleys.
Described sieve breaks system layout and has three layers, carrys out the bed of material at the top belt feeder and sets screening plant, and it is made up of 1# supplied materials belt feeder, stock guide switch, 2# screening belt conveyer, dust cover, screening machine；It is provided with disintegrating machine and material blanking tube intermediate crusher one layer；It is provided with 3# belt feeder at the bottom.
Described sieve breaks system and arranges that being provided with stock guide in the middle of 1# supplied materials belt feeder and 2# screening belt conveyer switchs, and switches about guide switch and can realize with or without sieving technology.
Described guide switch is manual and electronic two types, and electronic guide switch is connected with middle control, can realize interlocking start-stop remotely and on the spot.
Described sieve breaks system and arranges that 2# screening belt conveyer is positioned at screening machine compass screen surface top, and 2# screening belt conveyer one end fetches material belt machine tail part material, and other end material is delivered to screening machine feeding mouth.
The screening machine that described sieve breaks during system is arranged is connected to two tapping channels, and the passage being positioned at screening machine compass screen surface lower end is qualified particle diameter material blanking tube passage 1, and the passage being positioned at screening machine discharge port end is not qualified particle diameter disruption channel 2.
Disintegrating machine rear end during the broken system of described sieve is arranged is connected to form the material blanking tube in disintegrating machine cavity with screening machine qualified particle diameter material blanking tube, and after crusher in crushing, qualified particle diameter material and screening machine siftage qualified particle diameter material are met to 3# belt feeder.
Described sieve breaks system arrangement technology interlocked control start-stop order: rise, after opening 3 belt feeder normal operations, it is then turned on disintegrating machine, after disintegrating machine normal operation, it is then turned on screening machine, after screening machine normal operation, it is then turned on 2# and sieves belt conveyer, after 2# screening belt conveyer normal operation, then switch guide switch, finally open 1# supplied materials belt feeding.It is then contrary with opening sequence that interlocking stops sieving brokenly system arrangement technology.
Described 1# supplied materials belt, 2# screening belt conveyer, the bandwidth of 3# belt feeder, belt speed are the most consistent.
Described dust cover is to be connected with screening machine casing, it acts primarily as and prevents coal ash from leaking, there are sifted shaft portion and 2# screening belt conveyor and roller rack in dust cover, outside dust cover, are provided with screening machine, belt conveyer motor, automatically controlled, bearing driving device and rosette.

Accompanying drawing explanation
Fig. 1 is that the present invention sieves brokenly system arrangement technology principle schematic
In figure, 1-1# supplied materials belt feeder, 2-stock guide switchs, and 3-2# sieves belt conveyer, 4-dust cover, 5-screening machine, 6-material blanking tube, 7-disintegrating machine, 8-3# belt feeder.
Detailed description of the invention
The present invention will be further described with embodiment below in conjunction with the accompanying drawings:
As shown in Figure 1；Breaking building for three layer screen in figure, carry out the bed of material at the top belt feeder and set screening plant 1# supplied materials belt feeder 1, stock guide switch 2,2# sieves belt conveyer 3, dust cover 4, screening machine 5；It is provided with disintegrating machine 7, and material blanking tube 6 intermediate crusher one layer；It is provided with 3# belt feeder 8 at the bottom.
The operation principle process of present example is as follows:
If supplied materials 1000t/h；Particle size range 0-300mm；Qualified particle diameter needed for technique is 13mm；Wherein in supplied materials, qualified particle diameter accounts for 75%, and sifted component efficiency is 95%.
As shown in Figure 1, material 1000t/h switchs 2 from 1# supplied materials belt feeder 1 supplied materials to stock guide, guide switch switches to 2# and sieves belt conveyer 3 feeding, and screening machine 5 feeding mouth fallen into by material, and screening machine 5 particle diameter qualified to 0-13mm falls to material blanking tube 6 to 3# belt feeder 8 after sieving；On screening machine compass screen surface, the not qualified particle diameter of 13-300mm is fallen into disruption channel and is entered disintegrating machine and carry out being crushed to the qualified particle diameter of 0-13mm, then is joined by the material after material blanking tube 6 to 3# belt feeder 8 and screening, completes to sieve brokenly operating mode.
As it is shown in figure 1, material 1000t/h switchs 2 from 1# supplied materials belt feeder 1 supplied materials to stock guide, guide switch switches to disruption channel, and 1000t/h material does not directly fully enter crusher in crushing to 0-13mm by screening, then is delivered to lower road operating mode by 3# belt feeder 8.
The broken system of sieve is one of industrial and mining establishment's nucleus equipment, if this enterprise is provided without screening plant and will bring many unfavorable factors to follow-up operating mode: disintegrating machine power is excessive, the abrasion aggravation of disintegrating machine putty, grinder hammerhead, qualified particle diameter are crossed broken serious, material and do not met working condition requirement, energy consumption increase etc. negative issue.
