Background technology

At present, the Metal Melting industry, need be cooled off metal fragments such as neodymium iron borons after the melting in the time of hydrogen storage material at melting powder metallurgy raw material, particularly neodymium iron boron, because of agglomerative fragment temperature just can reach more than 500 degrees centigrade.Existing method of cooling is to adopt aqueous cold plate to cool off, be about to after the melting tentatively the particle of solidification forming pour in the aqueous cold plate and then in cooling tank, cool off.Because cooling tank is wholely set, therefore smelted once the back stove needs blowing out at every turn, and melted product is cooled off. after to be cooled the finishing product is cleaned out casing, just can restart melting after vacuumizing once more.Such technological process is unfavorable for enhancing productivity.In addition, be subjected to the restriction of box height, the size of aqueous cold plate is restricted, in order to increase the capacity of aqueous cold plate, can only strengthen the aqueous cold plate size, the drawback of bringing thus is to make the intravital vacuum tightness of case be not easy to reach the melting requirement, directly influences the quality of production. therefore existing aqueous cold plate can not do too big, still can't carry the product of many stoves, cooling efficiency is low.

Summary of the invention

The purpose of this utility model promptly produces thus, proposes a kind of cooling rewinding jar.Fragment cools off separately to make high temperature hasten with fixed attention, effectively shortens the production time, enhances productivity.

The technical scheme that the utility model implementation above-mentioned purpose is taked is: it is mainly by push-pull valve, tank body, cooling umbrella and intercooling return water pipe are formed, tank body is sealed intercalated water sleeve structure, which is provided with opening for feed, discharge port, tank body water-in and water outlet, opening for feed top at tank body is provided with push-pull valve, the cooling umbrella is arranged on the upper end of intercooling return water pipe in the tank body, the intercooling return water pipe is a hollow structure, its lower end is communicated with the intercalated water sleeve of tank body, is provided with the intercooling water inlet pipe in it.

The utility model is reasonable in design, and mechanism is simple.Because smelting furnace separates setting with cooling rewinding jar, therefore can cool off separately and discharging the product after the melting, promptly behind melting one stove, product impouring cooling tank is cooled off, do not influence the melting of next stove, discharging after melting is finished, after also can concentrating melting 3-4 stove. concentrate discharging, improved production efficiency more than 50%.The opening for feed of tank body is provided with the corrugated tube that is connected with the discharge port of melting equipment can play the buffering connection, can reduce damping vibration, reduces the possibility of the gas leakage of top melting casing.The setting of cooling umbrella can make the product that enters in it be broken and be cooled off once more, and can prevent effectively that thermal radiation is to sealing-ring influence on the push-pull valve.And cooling rewinding jar generally all adopts the design of embedded, i.e. tank body design is at underground, and this kind design can not take too many space, particularly ground space.
