Description
Technical field
The utility model relates to the sizing retracting device in CEMENTED CARBIDE PRODUCTION field, relates in particular to the retracting device of carbide alloy spray drying tower fused glass inside.
Background technology
When prepared by the compound in hard metal article production, first material powder (normally refractory carbide+Binder metal+additive) for example, is carried out to ball milling under organic liquid medium (alcohol), then the compound slip drawing off in ball mill is dried.The spray-dired mode of dry employing mostly.
In the drying tower of spray drying system, pass into heat-carrying gas (conventionally adopting nitrogen) the formation thermal current that is heated to uniform temperature, compound slip is under high pressure emitted into the drop group of fine drop through nozzle, drop group and heat-carrying gas even contact are dried.
In above-mentioned spray-drying process, understand some compound and be attached on drying tower inwall.Even if the vibrator rapping tower body that use tower body is around set up, also cannot all shake these compounds to fall, 2.3% left and right that generally accounts for output adhering on inner wall of tower after rapping.Therefore after each spraying operation completes, or while changing the compound trade mark, must there is the operation of cleaning drying tower (removing is attached on the compound on drying tower inwall).
The spray drying system that known a kind of model is PGX-100, after spraying operation completes, the purging system of starting drying tower, rinses inner wall of tower with high pressure (5MPa) hot water (65 ℃).In hot water, added washing agent.To the compound with under current, first with sedimentation basin, reclaim, and then row subsequent treatment.Its advantage is production safety and can cleans out.But mainly there are two shortcomings: compound severe oxidation, dirtyization that reclaim from sedimentation basin (1), reduced to " defective material " level, even after the physico-chemical process of follow-up series of complex is processed, also difficulty is secondary use.So in fact cause compound waste.Aforementioned known, this part compound reaches 2.3%; (2) sewage quantity that flushing produces is many, and this spray drying system rinses drying tower at every turn and produces sewage 2.4m
3, sewage is containing washing agent and compound powder remnants etc., and complicated component, processes difficult by environmental requirement.
Utility model content
The utility model object is to provide a kind of sizing retracting device, allows to realize the safe and effective compound being attached on drying tower inwall of collecting at low cost, and the compound non-oxidation of collection, without dirtyization, can be used by secondary in production.
According to sizing retracting device of the present utility model, comprise: gas pressure vessel, liquid container, flushing spray gun, spray drying tower.Liquid in the airtight liquid container of gas-loaded in gas pressure vessel, rinses spray gun and can insert in spray drying tower, makes liquid enter via rinsing spray gun the inwall that rinses spray drying tower in spray drying tower.
At gas pressure vessel place or between gas pressure vessel and liquid container, can be furnished with valve, the pressure that the gas via it in can adjustments of gas pressure vessel loads the liquid in liquid container.
According in sizing retracting device of the present utility model, the liquid in liquid container is alcohol.
According in sizing retracting device of the present utility model, the gas in gas pressure vessel is inert gas.
According in sizing retracting device of the present utility model, from rinsing spray gun alcohol out, be the normal temperature alcohol that does not contain washing agent, it has the pressure of 0.8MPa-1.0MPa.
According in sizing retracting device of the present utility model, spray drying tower has fastening cover, is provided with therein center through hole, rinses spray gun and can insert in spray drying tower from the center through hole of fastening cover.
According in sizing retracting device of the present utility model, rinse spray gun and there is spray boom, it can be free to slide or rotate to regulate the length stretching in tower in through hole.
According in sizing retracting device of the present utility model, at the front end place of rinsing spray gun, be provided with active joint, at active joint, place is provided with shower nozzle.The alcohol of spray gun ejection is spurting, directly impact tower wall.The spray angle of shower nozzle can regulate, thereby can rinse easily the place of wanting arbitrarily flushing in drying tower.
According in sizing retracting device of the present utility model, between liquid container and flushing spray gun, can be furnished with another valve, the flow of its adjustable liquid flowing out from liquid container.This valve also can be arranged on the end of rinsing spray gun.
Simple in structure according to sizing retracting device of the present utility model, installation and dismounting are all easy to, easy to operate.
Accompanying drawing explanation
Next set forth with reference to the accompanying drawings preferred embodiment of the present utility model.Wherein:
Fig. 1 shows according to the schematic diagram of sizing retracting device of the present utility model,
Fig. 2 shows according to the schematic diagram of flushing spray gun of the present utility model and fastening cover.
List of parts
1 gas pressure vessel
2 liquid containers
3 rinse spray gun
4 spray drying towers
5 valves
6 valves
7 spray booms
8 fastening covers
9 active joints
10 shower nozzles.
The specific embodiment
Fig. 1 is schematically illustrated according to sizing retracting device of the present utility model.It has: gas pressure vessel 1, liquid container 2, flushing spray gun 3 and spray drying tower 4.Gas pressure vessel 1 is equipped with inert gas, and inert gas is to the alcohol pressurization in liquid container 2, and pressure can regulate by valve 6.Containing the normal temperature alcohol of washing agent, from rinsing spray gun 3 pressure out, be not 0.8MPa-1.0MPa.Alcohol flow can be regulated by valve 5.The alcohol ejecting rinses the inwall of spray drying tower 4.The liquid that contains compound and the alcohol stream rinsing, through precipitation, vacuum drying treatment, alcohol and respectively recovery separation with compound.The compound non-oxidation of collecting is without dirtyization.
Fig. 2 is schematically illustrated according to flushing spray gun 3 of the present utility model and fastening cover 8.After spraying operation, install and rinse spray gun 3, it is fixed on spray drying tower 4 places via fastening cover 8.Spray gun front end inserts in drying tower from the center through hole of fastening cover 8, and the spray boom 7 of spray gun can be free to slide and rotate in through hole, and spray gun front end is provided with the adjustable shower nozzle 10 of angle by active joint 9.Valve 5 in Fig. 1 is arranged on spray gun end.The alcohol that flushing spray gun 3 sprays is spurting, directly impact tower wall.In course of injection, rinsing spray gun 3 can hand rotation, to regulate the length stretching in tower.The spray angle of shower nozzle is adjustable, thereby can realize the jet cleaning without dead angle to drying tower inwall.
Utilization is according to sizing retracting device of the present utility model, and alcohol consumption is about sixtieth of prior art water consumption, because pressure is lower, can wash down all gluing 80% of wall compound, and also recyclable with the alcohol of crossing.Next recycle the spray drying system of PGX-100, with high pressure (5MPa) hot water (65 ℃), drying tower inwall is rinsed in short-term, each used time and water consumption are only about 1/3rd of prior art.Generally speaking, compared with prior art reduced by 80% defective material, only produced about 0.45% defective material, therefore greatly reduced the waste of compound; But also alleviated environmental protection pressure (sewage only have original 1/3).Thereby produce larger economic benefit.
