Description
Technical field
The utility model relates to vacuum smelting fast solidification stove, the air-cooled circulating water device of especially a kind of vacuum smelting fast solidification stove.
Background technology
At present, vacuum smelting fast solidification stove is under vacuum or protective atmosphere, through eddy-current heating metal or alloy is melted, and through with water-cooled copper rod metal or alloy being cooled off fast, forms specific crystal or non crystalline structure material then.In this process, there is a large amount of used heat to produce; The heat of a part can directly be taken away by water; Part used heat needs to take away with protective gas earlier; These protective gas that contain used heat can not discharge, and need heat exchanger and pass to cooling water to this part used heat, let cooling water take away this part used heat.Yet; The temperature of protection gas but need be cooled to 15-26 ℃ up to 200 ℃, and the inflow temperature of the cooling water in the actual production is 15-26 ℃; Be normal environment temperature, cooling device will be cooled to 15-26 ℃ to the temperature of protection gas with such water temperature in the existing vacuum smelting fast solidification stove; Through long-term a large amount of investigation, find in the existing vacuum smelting fast solidification stove cooling device in the later stage of cooling, the temperature of protection gas is during less than 60 ℃, owing to have a narrow range of temperature, heat transfer efficiency is very low, needs the time of cooling long.The temperature cooling of protection gas is not got off, and is difficult to be cooled to 15-26 ℃; Next step operation cannot be carried out, and seriously restricts the production efficiency of whole vacuum smelting fast solidification stove.Therefore, expend mass energy and time, reduced operating efficiency and product quality, can not guarantee the normal and stable operation of producing.Take a lot of work, time-consuming, effort, labour intensity is heavy.Be that this area is difficult to the technical problem that overcomes for a long time, become the bottleneck of whole vacuum smelting fast solidification stove in producing, can not satisfy market and user's demand.
In view of above-mentioned reason, cooling device need be innovated improvement in the existing vacuum smelting fast solidification stove.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, to provide a kind of vacuum smelting fast solidification stove air-cooled circulating water device, and it is fast again that the cooling velocity of protection gas in the vacuum smelting fast solidification stove is added, and shorten half the cool time; Greatly energy savings and time, obviously increase work efficiency and product quality, make the production efficiency of whole vacuum smelting fast solidification stove improve 50%.The normal and stable operation of guaranteeing to produce.
The utility model is in order to realize above-mentioned purpose; Adopt following technical scheme: the air-cooled circulating water device of a kind of vacuum smelting fast solidification stove is to be made up of: vacuum melting chamber, gas-liquid two-phase heat exchanger, circulating fan, freezing unit, inlet channel, water return pipeline, circulation water pot; Vacuum melting chamber one side is provided with the gas-liquid two-phase heat exchanger through plumbing installation, and gas-liquid two-phase heat exchanger one side is provided with circulating fan through plumbing installation; The inlet channel of gas-liquid two-phase heat exchanger one side and the other end of water return pipeline are provided with the circulation water pot, and the gentle liquid two-phase heat-exchanger of circulation water pot is set up in parallel inlet channel and water return pipeline between the two; Connect between inlet channel and the gas-liquid two-phase heat exchanger freezing unit is set.
The parallelly connected plumbing installation that is provided with of bypass between circulating fan and the vacuum melting chamber.
The operation principle of the utility model is: the gas-liquid two-phase heat exchanger is connected in series through water route (inlet channel, water return pipeline) and circulation water pot and freezing unit; The water outlet of circulation water pot gets into freezing unit; After being cooled to 10-15 ℃, water gets into the gas-liquid two-phase heat exchanger; The gas-liquid two-phase heat exchanger the heat transferred recirculated water in the protection gas in the vacuum smelting fast solidification stove, reduces the temperature of protection gas through heat exchange, and the temperature of recirculated water is elevated to; Recirculated water is taken away the heat in the protection gas, and backwater gets into the circulation water pot.Recirculated water can directly be discharged, or after the air heat radiation, reuses.So, the circulation cooling reduces the cool time of protecting gas in the vacuum smelting fast solidification stove, improves the production efficiency of vacuum smelting fast solidification stove.
Wherein, said vacuum melting chamber is connected with circulating fan with the gas-liquid two-phase heat exchanger, and the indoor protective gas of vacuum melting comes back to vacuum melting under the effect at circulating fan after the cooling of gas-liquid two-phase heat exchanger indoor.The heat that the gas-liquid two-phase heat exchanger produces is recycled water and takes away, and in the initial period, when protective gas that vacuum melting is indoor and environment temperature differed big, good effect of heat exchange need not opened the vacuum unit; When the temperature of the protective gas in the vacuum working chamber during less than 50 ℃, the heat exchange effect reduces, and at this moment opens freezing unit and reduces the circulating water temperature that gets in the gas-liquid two-phase heat exchanger, improves heat exchange efficiency, reduces cool time, enhances productivity.
The beneficial effect of the utility model is: simple in structure, reasonable in design, and manufacture and install, safeguard that easy to use, handling safety is quick easily; Make the cooling velocity of protection gas in the vacuum smelting fast solidification stove accelerate one times, shortened cool time half the; Practiced thrift the energy and time greatly, obviously improved operating efficiency and product quality, made the production efficiency of whole vacuum smelting fast solidification stove improve 50%.The normal and stable operation of guaranteeing to produce.
The utility model with freezing unit the circulating water cooling that gets into the gas-liquid two-phase heat exchanger to 10-15 ℃; When the gas-liquid two-phase heat exchanger is cooled to 60 ℃ to 25 ℃ with the protection gas in the vacuum smelting fast solidification stove again; 10-50 ℃ the temperature difference is just arranged; Be twice because the existence of such temperature difference, the cooling velocity of the interior protection of vacuum smelting fast solidification stove gas just can add, shorten half the cool time than the system that does not add freezing unit.The production efficiency of whole vacuum smelting fast solidification stove can improve half the.
The utility model has solved this area and has been difficult to the technical problem that overcomes for a long time, satisfies market and user's demand.The saving of labor, save time, laborsaving, effectively reduce labor intensity; And invest lowly, be convenient to promote.
