Description
Technical field
The present invention relates to a kind of continous way sub-zero treatment and tempering equipment.
Background technology
Behind conventional quenching, also to carry out subzero treatment than the part that higher part and residual austenite exceed standard for distortion and the requirement of stable mechanical performance property in the military service process, make residual austenite be transformed into martensite.Generally all should there be sub-zero treatment equipment-deep cooling box most of heat treatment plants.The operating temperature range of general deep cooling box is between-80 to-120 ℃.
The refrigeration of modal deep cooling box has two kinds: i.e. mechanical refrigeration mode and liquid nitrogen refrigerating mode.The energy consumption of mechanical refrigeration mode mainly is the power consumption of compressor, and liquid nitrogen refrigerating is to consume liquid nitrogen (liquid nitrogen also is a kind of energy, because it obtains through consumes energy).
All deep cooling boxes all are single cell structure at present, with reference to shown in Figure 1.The discharging of must opening the door after processing finishes so air just must get into deep cooling box, contains moisture in the air again, and deep cooling box will freeze.Deep cooling box freezes can influence heat exchange efficiency on the one hand, can reduce the heat-insulating capability of tank wall on the other hand, causes energy consumption to increase.In addition since the part behind the deep cooling immediately as in the air, its surface at first can freeze, along with temperature rises, the ice-out Cheng Shui on surface possibly make part get rusty.For fear of these problems, must be before deep cooling box is lowered the temperature after charging with air in the nitrogen amount nitrogen replacement case, deep cooling also must be warmed up to part and deep cooling box more than the room temperature after finishing, and the deep cooling box with tempering function directly is warmed up to tempering temperature.Again must be cooled to cryogenic technology temperature to part and deep cooling chamber during deep cooling next time.That is to say that people only think cooling and heated components (prevent part from seeing behind the air freeze) in fact, but must cool off deep cooling box together and heat in fact at every turn, waste mass energy.For the deep cooling box of liquid nitrogen refrigerating, all be directly to feed liquid nitrogen in the case at present, directly be discharged to atmosphere after the heat absorption; Waste a large amount of high pure nitrogens, and use other HTFX in the workshop of deep cooling box, (must there be the equipment that needs nitrogen in this workshop like carburizing and quenching equipment; Because want the part of deep cooling; In carburizing glowing furnace, handled, and carburizing glowing furnace must need nitrogen), but need a large amount of nitrogen as other thermal treatment process protection gas.
Summary of the invention
Technical problem to be solved by this invention is that deep cooling and tempering are accomplished on same tinuous production, avoids deep cooling box to be cooled off repeatedly and heats, and reclaim the nitrogen behind the refrigeration liquid nitrogen vaporization, reach energy-conservation with reduce the purpose that workshop nitrogen consumes.
In order to solve the problems of the technologies described above, technical scheme of the present invention is following:
A kind of continous way sub-zero treatment and tempering equipment comprise deep cooling box and tempering stove, it is characterized in that; Described deep cooling box comprises chamber after charging cup, deep cooling chamber and the discharging, and the chamber is located at the front side and the rear side of deep cooling chamber respectively after charging cup and the discharging, and charging cup front end is provided with the charging closing door; Be provided with the first sealing inside door between charging cup and the deep cooling chamber, be provided with the second sealing inside door after deep cooling chamber and the discharging between the chamber, the rear end, chamber is provided with the discharging closing door after the discharging; The chamber connects discharging mechanism after the discharging; Discharging mechanism connection horizontal pushing mechanism, horizontal pushing mechanism connects pusher, and described tempering stove comprises heating chamber; Pusher connects heating chamber, and the chamber all is connected with nitrogen circulating system with pumped vacuum systems after charging cup and the discharging.
Preferably, described deep cooling chamber connection nitrogen circulating system.
Preferably, famine all is provided with the liquid nitrogen vaporization device in indoor cooling area and the heat preservation zone of being provided with of described deep cooling, cooling area and heat preservation zone.
Preferably, the top of described deep cooling chamber and heating chamber all is provided with circulation motor.
Preferably, all be provided with metal water conservancy diversion horse not in described deep cooling chamber and the heating chamber.
Preferably, all be provided with tubular heater in chamber and the heating chamber after the described discharging.
Beneficial effect of the present invention is:
1, the present invention adopts the continous way deep cooling box of chamber behind the vacuum air-changing of band vacuum air-changing cup and band heating function, air admission cyrogenic region when avoiding input and output material, thus avoid repeatedly the cooling of deep cooling chamber and heat up, thus reach purpose of energy saving;
2, the present invention adopts liquid nitrogen vaporizer that deep cooling box is freezed, and collects the high pressure nitrogen after heat absorption is vaporized through high pressure tank.Collect nitrogen and wash the front and back air-exchanging chamber of deep cooling box self, also have a large amount of nitrogen can be used to do the safe gas and protection gas of other HTFX of workshop except that being used for.Thereby reduce the nitrogen total amount consumed in whole workshop;
3, be equipped with the part tempering of continuous tempering stove after behind the continous way deep cooling box, make the tempering stove heating chamber be in tempering temperature all the time deep cooling, and needn't with part intensifications of lowering the temperature together, heat energy consumption thereby reduce.Because avoided the repeated heating and the cooling of heating, energy consumption is low;
4, deep cooling box and tempering stove form automation line, avoid artificial transfer work, and hand labor intensity is low.
