Description

The online screening plant of lime
Technical field
The utility model relates to a kind of material screen and divides device, relates in particular to a kind of online screening plant of lime that matches with the steel mill feeding system.
Background technology
China's overwhelming majority iron and steel enterprise adopts the pneumatic steelmaking of oxygen top bottom blowing at present; In convertor steelmaking process, (especially make steel the initial stage) and need in converter, add lime or light-burned block of material improves slag making speed; And be in great demand; Transportation to lime or light-burned block of material relies on belt conveyor basically, and the characteristics of belt conveyor are that speed is fast, and the unit interval upwards of movement is many.For more than again one of the belt conveyor carrying lime or light-burned block of material and install, just must guarantee that the travelling speed of this vibratory sieve is not less than the transporting velocity of belt conveyor at a steel-making enterprise, otherwise very easily cause lime or light-burned block of material overheap and end the transportation of belt conveyor on vibratory sieve if common vibratory sieve is installed between each belt conveyor; Before the utility model; How to coordinate the throughput rate relation of belt conveyor and vibratory sieve, guarantee normally carrying out of steel-making, also do not have relevant report; Generally speaking; Lime or light-burned block of material do not sieve before going into converter, and piece material and powder together get in the converter, and not only having caused wastes but also contaminated environment.
Summary of the invention
The purpose of the utility model is to provide a kind of online screening plant of lime that on the supply line of lime or light-burned block of material, can guarantee vibratory sieve and the operation of belt conveyor synchronous high-efficiency.
For realizing above-mentioned purpose; The technical scheme that adopts in utility model is: the online screening plant of described a kind of lime comprises first belt and second belt, two blanking channel funnel, vibratory sieve, flue-dust retainer, flap valve, vibrating motor and conveyance conduit, at the other pair blanking channel funnels that are equipped with of the side of first belt, in two blanking channel funnels, flap valve is housed; There are non-screening passage and screening passage in the both sides of flap valve; In the lower end of non-screening passage second belt is arranged, in the lower end of screening passage vibratory sieve is installed, vibratory sieve is driven by vibrating motor; Flue-dust retainer is contained in the lower end of vibratory sieve, and ash conveying pipe connects the outlet of flue-dust retainer.
Adopt the online screening plant of a kind of lime that as above technical scheme provides compared with prior art, technique effect is:
1. transporting velocity is fast, and bearing capacity is many, is not easy to damage the sieve plate of vibratory sieve.
2. overall process can rely on the PLC control of original system, need not increase equipment investment and human resources.
3. can select sieve plate as requested, interchangeability is strong, high efficiency.
Description of drawings
Fig. 1 is the device layout sketch map of the online screening plant of the described a kind of lime of the utility model, also is the Figure of abstract of the utility model.
Fig. 2 is the lime storage device side schematic view that matches and use with Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to describe in detail.
As shown in Figure 1, the online screening plant of the described a kind of lime of the utility model comprises first belt 1 and second belt 5, two blanking channel funnel 2, vibratory sieve 3, flue-dust retainer 4, flap valve 6, vibrating motor 7 and ash conveying pipe 8.At the other pair blanking channel funnels 2 that are equipped with of the side of first belt 1, said first belt 1 is a prior art, and the installation site is fixed.In two blanking channel funnels 2, flap valve 6 is housed, there are non-screening passage (a) and screening passage (b) in the flap valve both sides, in the lower end of non-screening passage (a) second belt 5 are arranged, and said second belt 5 also is a prior art, and the installation site is fixed.Lower end at screening passage (b) is equipped with vibratory sieve 3, and vibratory sieve 3 is driven by vibrating motor 7, and flue-dust retainer 4 is contained in the lower end of vibratory sieve 3, and ash conveying pipe 8 connects the outlet of flue-dust retainer 4.
Pneumatic actuation is adopted in the control of the flap valve 6 in two blanking channel funnels 2, and the vibrator of source of the gas reversal valve and low level feed bin blowing is chain.When the low level feed bin of dress lime or light-burned block of material began feed, PLC control vibratory sieve 3 was started working, and cylinder will drive flap valve 6 and close non-screening passage (a); And when other raw material need not to screen; Air cylinder driven flap valve 6 cuts out screening passage (b); The raw material that need not to screen can be delivered to second belt 5 by non-screening passage (a) and transport to required place, and lime or light-burned block of material of needs screening are then selected to screen passage (b), and flap valve 6 can be controlled; The steel plate of flap valve 6 is angled with the hopper walls of both sides all the time, play the guiding role during blanking.
Vibratory sieve 3 adopts the slanted screen form; Sieve plate on the vibratory sieve 3 and horizontal inclination angle are 30~40 degree (the best is 35 degree); Adopt the sieve plate that tilts to make things convenient for the bigger lime of diameter, light-burned block of material to tumble on second belt 5, reduce the live load and the passage that blocks vibratory sieve 3 of sieve plate because of deadweight.Lime after the screening or light-burned block of material are fallen on second belt 5; Send into converter as steelmaking slagging material etc. by second belt 5; Powder after the screening is collected through the flue-dust retainer under the vibratory sieve 34; Deliver to through ash conveying pipe 8 again and hold ash bucket 9, regularly open push-pull valve 10, dust is transported make other usefulness through the ash-unloading hopper 11 fortune car of packing into.
