Abstract
The utility model relates to a drying device for hard alloy mixture, which adopts a steam jacket to heat a hard alloy mixture so that the temperature of the hard alloy mixture rises and a liquid-state grinding medium changes to gas state and is separated from the hard alloy powder, wherein the hard alloy mixture is heated in a closed system in vacuum state and the gas-state grinding medium is condensed to liquid in vacuum state. The drying device consists of a steam vibration drier, vacuum pipes, condensing equipment, a vacuum pump and a recovery tank, wherein the vacuum pipes are used for respectively connecting the gas outlet of the steam vibration drier with the condensing equipment, the recovery tank and the vacuum pump to form a sealed vacuum system. The utility model can rapidly and completely separate the gasified grinding medium from powder through vacuum suction without spraying the tail gas, thus generating no external spraying powder, saving the precious resources, purifying the production environment, preventing the powder from contacting with air and solving the problem of oxygen aeration in the material.
Description
Technical field
The utility model relates to a kind of drying device of carbide alloy mixture, especially the vibration drying device of fine grained and ultra-fine grain carbide alloy mixture.
Background technology
Carbide alloy is as " tooth " of industry, and its application just progressively enlarges, and is bringing into play more and more important effect.In the CEMENTED CARBIDE PRODUCTION process, need the compound slip is carried out drying,, obtain the trade mark powder of technological requirement so that the powder in the slip is separated with abrasive media, and reclaiming abrasive media safely, common slip drying process has: spray-drying, vacuum drying, vibration drying etc.
Spray-drying is to utilize hot nitrogen directly the slip drop that sprays in the tower body to be heated, abrasive media is separated with slip, reach dried material and reclaim the purpose of abrasive media, it can a step finish the drying of slip and the task of granulation two-step, the automaticity height, but this system is huge, and floor space is big, factory building height is high, one-time investment is big, operating cost is high, is not suitable for the production of small lot, many kinds.
Vacuum drying be under vacuum state with the slip indirect, make abrasive media reach evaporating temperature and become gaseous state, introduce condenser by vacuum and carry out condensation and reclaim.As adopt the double cone vacuum desiccator, place the slip in the double cone body under the effect of double cone body wall chuck hot water (or deep fat), to be heated, abrasive media wherein reaches evaporating temperature and becomes gaseous state, under the attraction of vavuum pump, enter condenser through vacuum pipe, being cooled is reduced into liquid state, flows into the medium storage tank and is recovered.Advantages such as with respect to spray-drying, it is simple that vacuum drying has system, and floor space is little, and one-time investment is few.
Vibration drying is to the slip indirect under normal pressure, make abrasive media wherein become gaseous state, and the pressure in the container is raise, the abrasive media exhaust outlet from container under the effect of container inner pressure that has become gaseous state is discharged, introduce in the condenser by pipeline, carry out condensation and reclaim.Vibration drying device commonly used is that slip is placed in the cylinder, is heated under the effect of steam in cylinder body wall chuck, and abrasive media becomes gaseous state and leaves the charging cylinder from exhaust outlet, enters condenser through flexible pipe, is cooled to be reduced into liquid the recovery.Because this method need rely on self pressure that the gaseous state abrasive media is discharged, after abrasive media all evaporates, pressure in the container descends gradually, whole gaseous state abrasive medias can't be discharged, be head it off, common method is to pull out the flexible pipe that connects condenser at this moment and seal exhaust outlet for a moment, opens exhaust outlet then and goes out by gas in the cylinder (carrying partial material), in case of necessity repeatedly several times up to material being made a good job of (this process is commonly called as material spray).
This device has easy to operate; advantages such as one-time investment is few, but since material no nitrogen or vacuum protection in this process, easy and air generation oxidation; so its oxygen content is than above-mentioned two kinds of method height; especially fine grained and ultra-fine grain material are because its chemism is big, easily and air generation oxidation reaction; be difficult to control its oxygen content more; and, unavoidably causing the material waste, and severe contamination working environment owing to need carry out the material spray operation.
Summary of the invention
The purpose of this utility model aims to provide a kind of vibration drying device of new carbide alloy mixture, and it avoids the oxygenation problem of carbide alloy mixture in dry run, and avoids losing material, polluting production on-site environment because of material spray in the dry run.
The technical solution of the utility model is:
A kind of vibration drying device of carbide alloy mixture, it is made up of shake dried device, vacuum pipe, condensing plant, vavuum pump, recycling can of steam, described vacuum pipe connects the shake gas vent of dried device of steam successively with condensing plant, recycling can, vavuum pump, form the vacuum system of sealing, by the steam dried device heating of shaking, the abrasive media of gaseous state equipment of being condensed under vacuum state is condensed into liquid to described carbide alloy mixture in the closed system under the vacuum state.
As to further improvement of the utility model, described condensing plant journey is divided into one-level condensing plant and the B-grade condensation equipment that connects successively.
As to further improvement of the utility model, described B-grade condensation equipment is coil condenser.
As to further improvement of the utility model, the vacuum of described vacuum system is-0.06～-0.08MPa.
As to further improvement of the utility model, abrasive media is an alcohol in the described carbide alloy mixture.
The beneficial effects of the utility model are: the utility model is adopting steam material to be carried out on the dry basis abrasive media after carbide alloy mixture and the gasification is placed in the vacuum system of sealing, both can make the abrasive media that gasified and powder rapidly, separate fully by vacuum draw, need not to adopt the material spray mode to discharge tail gas, no powder sprays outward, the clean free from dust in production scene, both saved valuable resource, purified production environment again, also can avoid powder to contact, solve the problem of the easy oxygenation of material with air.
Utility model people adopts the steam oscillation device of device of the present utility model and prior art respectively the material to be dried of the YG6X trade mark to be processed, the comparative result of the oxygen content of gained material such as subordinate list one.
By the result of subordinate list one as can be known, adopt the material oxygen content of method and apparatus drying of the present utility model obviously to descend, effect is very remarkable.
Equipment of the present utility model only adds a cover vacuum abrasive media retracting device on the basis of former vacuum vibration drying device, equipment investment is few, and floor space is little.
