Abstract

Ultrafine tungsten powder cooling system; including coolant seal space, material barrel, freezing unit and protective gas, wherein, freezing unit includes interconnective heat exchanger and fridge; material barrel is placed in coolant seal space, and is placed with tungsten powder to be cooled in material barrel；Protective gas accesses heat exchanger by pipeline; the protective gas of low temperature is obtained after the chilled water made with fridge carries out heat exchange; the protective gas of low temperature is being connected with dehydrater by pipeline; it is positioned in the material barrel in coolant seal space being delivered to by pipeline except the protective gas after water through dehydrater, thus realizes tungsten powder protection to be cooled and cooling.The present invention uses dual-cooled mode directly to cool down tungsten powder to be cooled; indoor temperature is required the harshest; increasing a set of freezing unit on the basis of air-conditioned room to cool down protective gas, cost of investment is low with operating cost, good cooling results.

Description

Ultrafine tungsten powder cooling system
Technical field
The present invention relates to rare metal powder cooling technology field, particularly relate to a kind of ultrafine tungsten powder cooling system.
Background technology
Ultrafine tungsten powder still has higher temperature (about 40 DEG C) when being left in stove after high temperature reduction, if tungsten powder thing Material is not cooled down and is protected in time, then the moisture easily and in air reacts and then causes tungsten powder surface oxidation, Even there is spontaneous combustion.Current way is that tungsten powder material once leaves in stove, uses protective gas to tungsten powder immediately Protect, and tungsten powder is taked cooling measure.And existing cooling measure mainly has two kinds, one is to be placed by tungsten powder In freezer, this mode good cooling results, but cost of investment and operating cost are high；One is that tungsten powder is positioned over air-conditioned room, This mode small investment, but cooling effect is undesirable.
Summary of the invention
Technical problem solved by the invention is to provide a kind of ultrafine tungsten powder cooling system, to solve above-mentioned background skill Shortcoming in art.
Technical problem solved by the invention realizes by the following technical solutions:
Ultrafine tungsten powder cooling system, including coolant seal space, material barrel, freezing unit and protective gas, wherein, fridge Group includes interconnective heat exchanger and fridge, and material barrel is placed in coolant seal space, and is placed with in material barrel Tungsten powder to be cooled；Protective gas accesses heat exchanger by pipeline, carries out heat exchange at the chilled water made with fridge After obtain the protective gas of low temperature, the protective gas of low temperature is being connected with dehydrater by pipeline, through dehydrater except the guarantor after water Protect gas and be positioned in the material barrel in coolant seal space being delivered to by pipeline, thus realize tungsten powder to be cooled is protected Protect and cool down.
In the present invention, coolant seal space includes air-conditioned room or freezer.
In the present invention, heat exchanger is in parallel with fridge, and heat exchanger one end is connected with protective gas input, separately One end is connected with dehydrater.
In the present invention, material barrel is provided with closed opening, for being passed through the protective gas of low temperature.
Beneficial effect: in the present invention promotes material barrel by the way of reducing coolant seal space indoor air temperature indirectly Tungsten powder temperature to be cooled decline, in material barrel, be passed through the protective gas of low temperature simultaneously, dual-cooled mode is treated cold But tungsten powder directly cools down, and requires the harshest to indoor temperature, increases a set of freezing unit on the basis of air-conditioned room Cooling down protective gas, cost of investment is low with operating cost, good cooling results, can effectively stop tungsten to be cooled The moisture of powder and air reacts and causes surface oxidation, and spontaneous combustion even occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation of presently preferred embodiments of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot Conjunction is specifically illustrating, and the present invention is expanded on further.
See the ultrafine tungsten powder cooling system of Fig. 1, hand over including air-conditioned room 1, material barrel 2, dehydrater 3, chilled water 4, heat Parallel operation 5, fridge 6, protective gas 7 and tungsten powder to be cooled；Wherein, first to the protective gas being passed through in material barrel 2 First lower the temperature, then in being passed through material barrel 2, utilize the protective gas of low temperature tungsten powder to be cooled directly to be carried out cold But；After protective gas 7 is made of, being pipelined to heat exchanger 5, the freezing water 4 made with fridge 6 carries out heat Exchange obtains the protective gas 7 of low temperature, and the protective gas 7 of low temperature is pipelined to dehydrater 3, through except the protection after water Tungsten powder to be cooled, in being delivered to, through pipeline, the material barrel 2 being positioned in air-conditioned room 1, is protected and is cooled down by gas 7.
In the present embodiment, heat exchanger 5 is in parallel with fridge 6, and heat exchanger 5 one end and protective gas 7 input Connecting, the other end is connected with dehydrater 3.
In the present embodiment, freezer can be used to replace air-conditioned room 1, by by indirectly promoting in the way of reducing indoor air temperature Make the tungsten powder temperature to be cooled in material barrel 2 decline, in material barrel, be passed through the protective gas of low temperature simultaneously, utilize low temperature Protective gas tungsten powder to be cooled is directly cooled down；Tungsten powder to be cooled is directly carried out by dual-cooled mode Cooling, requires the harshest to indoor temperature, increases a set of freezing unit and carry out cold to protective gas on the basis of air-conditioned room But, cost of investment is low with operating cost, good cooling results, can effectively stop the moisture of tungsten powder to be cooled and air to be sent out Raw reaction causes surface oxidation, and spontaneous combustion even occurs.
