Description
Technical field
What the present invention relates to is the equipment in a kind of heat treatment technics field, specifically is a kind of heat treatment furnace that adopts heat pipe to quickly lower temperature.
Background technology
The heat treatment furnace effect is under atmosphere, under the protective atmosphere or under the vacuum processed workpiece is heated, is incubated, and then processed workpiece is taken out from heat treatment furnace and cools off or cool off according to the process for cooling of setting in heat treatment furnace.Carry out cooling purpose in order to be implemented in the heat treatment furnace according to the process for cooling of setting, many method of cooling are used.It is more common method that interchanger wherein is set in heat treatment furnace.The interchanger that it is heat-eliminating medium that one of method that interchanger is set in the heat treatment furnace is provided with a water in a certain position of heat treatment furnace body of heater exactly, when heat treatment furnace need be lowered the temperature by predetermined technology, this interchanger was stretched into the heating zone and is absorbed furnace heat.The other method that interchanger is set in the heat treatment furnace is provided with heating chamber and aircooling cabinet exactly in heat treatment furnace (mostly being vacuum heat treatment furnace), the pathway closure of aircooling cabinet and heating chamber when heating, aircooling cabinet and heating chamber passage are opened when cooling, by powerful blower fan gas is circulated between heating chamber and aircooling cabinet, the interchanger that the heat of round-robin gas is set in the cooling room is taken away, and realizes the purpose of cooling.It is bigger that the shortcoming of these methods is that interchanger takies the device space; Simultaneously owing to be to adopt water as heat transferring medium, for the temperature that makes interchanger self is not higher than the boiling point of water, in equipment heating and cooling process, need water flowing all the time in interchanger, cause equipment in heat-processed, also to have the part heat and taken away by interchanger; The cooling of interchanger need consume great amount of water resources and in case produce incrustation scale in interchanger heat exchange efficiency obviously reduced.
Find through literature search prior art, China Patent No.: CN02253382.6, name is called: Device for quickly cooling workpieces in heat treatment furnace, this patent disclosure a kind of Device for quickly cooling workpieces in heat treatment furnace, comprising: the utility model relates to a kind of Device for quickly cooling workpieces in heat treatment furnace.For solving the existing problem that heat treatment furnace production efficiency is low, energy consumption is high, it comprises cup, chamber, back and is used to separate the dodge gate of chamber, front and back, at cup top or both sides inlet pipe is housed, at top, chamber, back or both sides vapor pipe is housed, between air inlet-outlet pipe, is communicated with blower fan and flange-cooled pneumatic tube.Therefore, it has simple in structure, and is easy to operate, high efficiency, less energy consumption, the advantage that the workpiece quality of lowering temperature uniform and processing is good.The shortcoming of this device is that the cooling of flange-cooled pneumatic tube is to cool off under the state of nature, so refrigerative efficient is not high.Also find in the retrieval, China Patent No.: 01808413.3, name is called: gas-cooled single chamber heat treating furnace and method for gas cooling in this stove, this patent disclosure a kind of gas-cooled single chamber heat treating furnace and in this stove method for gas cooling, comprise: a kind of gas-cooled single chamber heat treating furnace, in this stove, the cooling gas ventilation opening that is opened and closed by door is set on the mutual relative wall of the inner room that forms treatment chamber, in the gas cooling process, open the cooling gas ventilation opening and come circulating cooling gas, the cooling of gas relies on built-in interchanger to carry out, the circulation of cooling gas relies on powerful blower fan, and interchanger is to rely on feeding water to carry out heat exchange.The shortcoming of this patent is that interchanger is to adopt water as heat transferring medium, the boiling point that is not higher than water for the temperature that makes interchanger self, in equipment heating and cooling process, need water flowing all the time in interchanger, cause equipment in heat-processed, also to have the part heat and taken away by interchanger.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, propose a kind of heat treatment furnace that adopts heat pipe to quickly lower temperature, make it when keeping rate of cooling to require, do not need consume water.
The present invention is achieved by the following technical solutions, the present invention includes: hot-blast outlet, the heat pipe heat radiation end, the cold wind blower fan, windsheild, Heat Room, the heat pipe heat absorbing end, thermal circulation fan, following ventilation opening, insulated wall, air deflector, heating chamber, last ventilation opening, power push-rod, cooling room, mode of connection is: the heat pipe heat absorbing end is installed in the Heat Room, the heat pipe heat radiation end is installed in the cooling room, the cold wind blower fan is installed in bottom at cooling room, top at cooling room is provided with hot-blast outlet, between Heat Room and heating chamber, insulated wall is set, on insulated wall, be provided with ventilation opening and last ventilation opening down, Heat Room one side in insulated wall is provided with the windsheild that is close to insulated wall, and windsheild connects with power push-rod.Thermal circulation fan is in the bottom of Heat Room, thermal circulation fan air outlet next-door neighbour's windsheild and following ventilation opening.Air deflector is in the bottom of heating chamber, and its opening surface is to the following ventilation opening of insulated wall.
When heat treatment furnace needs cooling fast, power push-rod is in punctured position, windsheild the power push-rod effect be moved to the following ventilation opening that makes on the insulated wall and last ventilation opening respectively with windsheild on during the state of the opening UNICOM that is provided with, high-temperature gas in the heating chamber just can the effect of thermal circulation fan with the heat of heating chamber from ventilation opening suck Heat Room, high-temperature gas in Heat Room with heat transferred heat pipe heat absorbing end, the heat pipe heat absorbing end is delivered to the heat pipe heat radiation end by the heat pipe effect with heat again, under the effect of the cold wind blower fan of heat pipe heat radiation end in cooling room by hot-blast outlet with heat release, through ventilation opening and air deflector that gas re-circulation is returned heating chamber again through overcooled gas in the Heat Room, thereby realize the quick cooling of workpiece in heat treatment furnace.In the heating phase, power push-rod is in extended position, and windsheild is moved to the following ventilation opening and the last ventilation opening that make on the insulated wall in the power push-rod effect and is blocked by windsheild respectively, and the high-temperature gas in the heating chamber can not enter Heat Room.The power of power push-rod can be hydraulic pressure, pneumatic and mechanical system.On windsheild, have and following ventilation opening and the corresponding hole of last ventilation opening.
Compared with prior art, the present invention adopts heat pipe as heat-exchanger rig, has the heat exchange efficiency height, has avoided adopting water, easily fouling and make device fabrication complicated problems big as the water loss that the interchanger heat exchange of heat transferring medium brings simultaneously.Because present hot pipe technique can produce can be at the product of 800 ℃ of following efficient operation steady in a long-term, so the application of heat pipe has obtained popularizing.Method of the present invention is specially adapted to need quick refrigerative heat treatment furnace after thermo-chemical treatment and the protective atmosphere thermal treatment.
