Abstract
The utility model provides a kind of fuel pre-screen device, comprises lower funnel, equal thick screen, motor, batch meter, turnover panel, vibrator, funnel for subsequent use, finished product funnel and finished belt; Equal thick screen front end is provided with lower funnel, middle part is provided with finished product funnel, finished belt is provided with below finished product funnel, motor is equipped with in equal thick screen rear end, motor shaft is connected with vibrator universal drive shaft, and vibrator is fixed on equal thick screen sieve plate base, and equal thick screen rear upper is tiltedly installed with batch meter, batch meter and funnel top for subsequent use interlink, and are flexibly connected one piece of turnover panel at batch meter with funnel junction for subsequent use by bearing pin.The utility model directly enters in finished fuels after the fuel of granularity < 3mm can be made to sieve, the part of granularity > 3mm is sent in four roller ore deposit grooves and is carried out fragmentation, thus greatly reduce crushing and wear and tear in machines, reduce electric energy and spare parts consumption, crossing of fuel is avoided to pulverize, improve the granularmetric composition of sintering deposit, improve the Quality and yield of sintering deposit.
Description
Technical field
The utility model belongs to sintering machinery apparatus field, particularly relates to a kind of pre-screen device for sintering fuel.
Background technology
The fuel granularity < 3mm grade that SINTERING PRODUCTION technological requirement uses must reach more than 85%.In actual production process, fuel is after four roller fragmentations, and the ratio of 0 ~ 1mm and > 3mm grade is the leading indicator of four roller fragmentations.Production practices prove, the fuel of 0 ~ 1mm grade can be pumped at the high negative pressure of main exhauster, and fuel is consumed in vain.And the fuel ratio of granularity > 3mm grade is too high, in sintering process, there will be partial combustion and cause local superfusion and the insufficiently burnt problem in other position.
The solid fuel that certain sintering plant is conventional has coke powder and anthracite, after testing, in coke powder, the part of granularity < 3mm reaches 56.7%, owing to there is no screening plant, make this part of coke powder can increase the weight of the mistake crushing phenomenon of coke powder again after four roller fragmentations, extend the duration of runs of fuel smashing system simultaneously, not only increase electric energy and spare parts consumption.And exacerbate the wearing and tearing of equipment, increase the regular maintenance amount of maintainer.
Summary of the invention
The utility model aims to provide a kind of part of granularity < 3mm in fuel can being separated in advance before fragmentation, avoids pulverizing, thus reduces production cost, improves the fuel pre-screen device of Sintering Operation Index.
For this reason, the solution that the utility model is taked is:
A kind of fuel pre-screen device, is characterized in that, comprise lower funnel, equal thick screen, motor, batch meter, turnover panel, vibrator, funnel for subsequent use, finished product funnel and finished belt; Lower funnel is provided with below equal thick screen front end, finished product funnel is provided with below middle part, finished belt is provided with below finished product funnel, motor is equipped with in equal thick screen rear end, motor shaft is connected with vibrator universal drive shaft, and vibrator is fixed on equal thick screen sieve plate base, and equal thick screen rear upper is tiltedly installed with batch meter, batch meter and funnel top for subsequent use interlink, and are flexibly connected one piece of turnover panel at batch meter with funnel junction for subsequent use by bearing pin.
Described equal thick screen adopts Bar strip type sieve plate.
The beneficial effects of the utility model are:
After using the utility model, directly finished fuels is entered into after accounting for the portion screen of the granularity < 3mm of fuel 56.7%, the part of granularity > 3mm then enters in four roller ore deposit grooves carries out fragmentation, not only greatly reduce the wearing and tearing of crushing and four-roller crusher, extend service life of equipment, and effectively reduce electric energy and spare parts consumption, reduce production cost.Meanwhile, crossing of fuel can be reduced and pulverize, improve the granularmetric composition of sintering deposit, improve the Quality and yield of sintering deposit.
Accompanying drawing explanation
Fig. 1 is fuel pre-screen apparatus structure schematic diagram.
In figure: oversize belt 1, lower funnel 2, floor 3, equal thick screen 4, motor 5, batch meter 6, bearing pin 7, turnover panel 8, charging belt 9, vibrator 10, funnel for subsequent use 11, finished product funnel 12, finished belt 13.
Detailed description of the invention
As seen from Figure 1, the utility model fuel pre-screen device, be on the basis of original oversize belt 1, charging belt 9 (being conveying belt originally) and floor 3, set up time funnel 2, equal thick screen 4, motor 5, batch meter 6, bearing pin 7, turnover panel 8, vibrator 10, funnel for subsequent use 11, finished product funnel 12 and finished belt 13.The equal thick screen 4 of Bar strip type sieve plate is adopted to be arranged on floor 3.Below the front end of equal thick screen 4, be provided with lower funnel 2, lower funnel 2 lower ending opening, above oversize belt 1, is pulverized again the oversize after sieve is transported to four roller pulverizer places.Be provided with finished product funnel 12 below the middle part of equal thick screen 4, finished product funnel 12 is provided with finished belt 13 below, the part of the granularity < 3mm under sieve is directly sent in finished fuels.Motor 5 is equipped with in the rear end of equal thick screen 4, and the motor shaft of motor 5 is connected with the universal drive shaft of vibrator 10, and vibrator 10 is fixed on the sieve plate base of equal thick screen 4, carries out vibrosieve by motor 5 and vibrator 10 pairs of equal thick screens 4.The inclined upward at equal thick screen 4 rear portion is provided with batch meter 6, and batch meter 6 and funnel 11 top for subsequent use interlink, and the tail end of charging belt 9 is positioned at the top of batch meter 6 and funnel 11 for subsequent use.Be flexibly connected one piece of turnover panel 8 by bearing pin 7, normal screen timesharing at batch meter 6 with the junction of funnel 11 for subsequent use, turnover panel 8 renovates funnel 11 for subsequent use, makes fuel enter equal thick screen 4 by batch meter 6; When pre-screen device breaks down, turnover panel 8 can be renovated batch meter 6, make fuel directly drop down onto on oversize belt 1 by funnel 11 for subsequent use, for sintering provides fuel, to ensure carrying out smoothly of production.
