Abstract
The utility model discloses a change grey system, it includes the material loading conveyer, changes the screw conveyer that ash machine, one -level stirred tank, second grade stirred tank, storage slag chute and slope set up, and the material loading conveyer is set up to the slope of discharge end from bottom to top by the feed end, high -end bottom at screw conveyer is equipped with row cinder notch, be equipped with the storage slag chute in row cinder notch below, low side top at screw conveyer is equipped with the feed inlet, the discharge gate below of feed inlet of the arranging in ash machine, low side tip at screw conveyer is equipped with the discharge gate. The advantage: by changing the mixed liquid of grey quick -witted exhaust entering screw conveyer, screw conveyer can separate away the bits that mix in the liquid, avoids bits to get into the stirred tank, prevents that the stirred tank from damaging, the fault rate is low, and then can reduce maintenance cost, reduction workman intensity of labour, the normal operating of assurance change grey system, it can carry out the secondary ash in screw conveyer inside to mix liquid simultaneously, and then improves slurry concentration, improves the utilization ratio of lime.
Description
Technical field:
The utility model belongs to ashing technical field, relates in particular to a kind of ashing system.
Background technology
Can produce a large amount of dirt acid in the process of Copper making, at present, the treating processes of dirty acid converts lime to calcium hydroxide milk of lime by ashing system, then calcium hydroxide milk of lime is transported to neutralized system by dirt acid neutralization; Ashing system is generally made up of lime slaking machine and two-stage steel basin, is mixed with lime by water in lime slaking machine, and part water and lime reaction form calcium hydroxide milk of lime, and water and the lime of not fully reaction continue to react in steel basin; But because lime contains a large amount of bits, so can containing a large amount of bits in the calcium hydroxide milk of lime formed after lime slaking machine ashing, bits in calcium hydroxide milk of lime deposition in steel basin, stirring arm heavy wear can be caused on the one hand, failure rate is high, maintenance cost is high, and need workman to arrive cleaning bits in steel basin, labor strength is large simultaneously; On the other hand, maintenance can cause ashing system normally to run, and then makes neutralized system be forced to stop, and dirty acid treatment efficiency is low.
Utility model content:
The purpose of this utility model is the ashing system providing a kind of failure rate is low.
The utility model is implemented by following technical scheme: ashing system, it worm conveyor comprising material conveyer, lime slaking machine, one-level steel basin, secondary steel basin, storage slag chute and be obliquely installed, described upper material conveyer is obliquely installed to discharge end from bottom to top by feed end; Be provided with fluid inlet at described worm conveyor top, be provided with slag-drip opening in the high-end bottom of described worm conveyor; Described storage slag chute is provided with below described slag-drip opening; Opening for feed is provided with at the low side top of described worm conveyor; Described opening for feed is placed in below the discharge port of described lime slaking machine, and the opening for feed of described lime slaking machine is placed in below the discharge end of described upper material conveyer; Discharge port is provided with, all by chute or pipeline connection between described discharge port and described one-level steel basin top, between described one-level steel basin side wall upper part and described secondary steel basin top in the low side end of described worm conveyor.
Described upper material conveyer is any one of endless belt conveyor, bucket conveyor or drag conveyer.
Described chute or described pipeline are obliquely installed to discharge end from top to bottom by material end.
Submersible pump is provided with in described secondary steel basin.
Advantage of the present utility model: the mixed solution of being discharged by lime slaking machine enters worm conveyor, bits in mixed solution can be separated by worm conveyor, bits are avoided to enter steel basin, prevent that steel basin from damaging, failure rate is low, and then maintenance cost can be reduced, reduce labor strength, ensure that ashing system is normally run; Mixed solution can carry out secondary ashing in worm conveyor inside simultaneously, and then improves concentration of slurry, improves the utilization ratio of lime.
Accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Upper material conveyer 1, lime slaking machine 2, one-level steel basin 3, secondary steel basin 4, storage slag chute 5, worm conveyor 6, fluid inlet 7, slag-drip opening 8, opening for feed 9, discharge port 10, submersible pump 11, chute 12.
Embodiment:
As shown in Figure 1, ashing system, it worm conveyor 6 comprising material conveyer 1, lime slaking machine 2, one-level steel basin 3, secondary steel basin 4, storage slag chute 5 and be obliquely installed, upper material conveyer 1 is obliquely installed to discharge end from bottom to top by feed end, and upper material conveyer 1 is carried to top by bottom; The opening for feed of lime slaking machine 2 is placed in below the discharge end of material conveyer 1; Fluid inlet 7 is provided with, by the inner adding liquid of fluid inlet 7 casees worm conveyors at worm conveyor 6 top; Slag-drip opening 8 is provided with in the high-end bottom of worm conveyor 6; Storage slag chute 5 is provided with below slag-drip opening 8; Be provided with opening for feed 9 at the low side top of worm conveyor 6, opening for feed 9 is placed in below the discharge port of lime slaking machine 2; Upper material conveyer 1 is endless belt conveyor; Be provided with discharge port 10 in the low side end of worm conveyor 6, be all communicated with by chute 12 between discharge port 10 with one-level steel basin 3 top, between one-level steel basin 3 side wall upper part with secondary steel basin 4 top; Chute 12 is obliquely installed to discharge end from top to bottom by feed end, can prevent the sedimentation in chute 12 of calcium hydroxide milk of lime, affect the circulation of chute 12; In secondary steel basin 4, be provided with submersible pump 11, the calcium hydroxide milk of lime in secondary steel basin 4 is pumped in neutralized system by submersible pump 8.
Principle of work: deliver in lime slaking machine 2 through the opening for feed of lime slaking machine 2 after lime is transported to top by bottom by upper material conveyer 1; Water and lime are in lime slaking machine 2 internal mix, and part water and lime reaction form calcium hydroxide milk of lime, and the mixed solution of calcium hydroxide milk of lime, bits and the water fully do not reacted, lime enters worm conveyor 6 inside; Bits in mixed solution are delivered in storage slag chute 5 by low side to high-end by worm conveyor 6; Water, the lime of calcium hydroxide milk of lime and not fully reaction enter one-level steel basin 3 and secondary steel basin 4 successively through discharge port 10, chute 12, water, the lime one-level steel basin 3 of calcium hydroxide milk of lime and not fully reaction fully react under acting on secondary steel basin 4, are finally all converted into calcium hydroxide milk of lime.
