Abstract
The utility model relates to a device for quickly cooling a workpiece in a heat treatment furnace. The utility model solves the problems of low productive efficiency and high energy consumption of existing heat treatment furnaces. The device comprises a front chamber, a rear chamber, a movable door used for separating the front chamber and the rear chamber, air inlet pipes arranged on the top or both sides of the front chamber, air outlet pipes arranged on the top or both sides of the rear chamber, a fan communicated between the air inlet pipes and the air outlet pipes and air delivery pipes with cooling fins. Therefore, the utility model has the advantages of simple structure, convenient operation, high work efficiency, low energy consumption, uniform cooling and good quality of the workpiece treated.
Description
Technical field
The utility model relates to Equipment for Heating Processing, particularly relates to a kind of Device for quickly cooling workpieces in heat treatment furnace.
Technical background
At present, in the Technology for Heating Processing later stages such as the carburizing of machine components, nitriding, carbo-nitriding, nitrocarburizing, workpiece need be lowered the temperature with stove, to reach the temperature of arts demand.Existing equipment can only lean on the outer surface of furnace wall that the accumulation of heat of workpiece and furnace lining is passed in the stove external environment condition, and this just needs long time, makes the process time lengthening on the one hand, and stove production efficiency is reduced; On the other hand, the furnace lining of being lowered the temperature is (because cooling back temperature of furnace lining is lower than workpiece temperature, this temperature difference is unnecessary, as long as because accomplish the workpiece cooling), following one-period will heat-treat to add and is raised to higher temperature man-hour again again, need to consume extra heat, must cause the unnecessary waste of energy.Therefore, existing equipment is given prominence to and is had the problem that production efficiency is low, energy consumption is high.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, and the Device for quickly cooling workpieces in heat treatment furnace of a kind of production efficiency height, less energy consumption is provided.
For achieving the above object, the utility model Device for quickly cooling workpieces in heat treatment furnace comprises cup, chamber, back and is used to separate the dodge gate of chamber, front and back, at cup top or both sides air inlet pipe is housed, at top, chamber, back or both sides blast pipe is housed, between air inlet-outlet pipe, is communicated with blower fan and flange-cooled appendix.
As optimization, between air inlet-outlet pipe, also be communicated with flow control valve.
As optimization, between air inlet-outlet pipe, also be communicated with cooler.
As optimization, the gas transmission direction of blower fan is to blast pipe from air inlet pipe.
As optimization, the stirring blower fan all is equipped with at the top of cup and chamber, back, and described air inlet-outlet pipe all is installed in the next door of stirring blower fan.
After adopting technique scheme, the blower fan of the utility model Device for quickly cooling workpieces in heat treatment furnace can adopt high temperature resistant, full seal type, this blower fan can suck cup stove waste gas after-acceleration, boost as the power of furnace atmosphere circulation system, and by sending into the back chamber (being heating clamber) of stove after pipeline and the cooler cooling.Flow control valve can be electronic, can be the hand switch valve also, utilizes the flow control valve size of adjustments of gas flow easily, thereby changes the cooling velocity of workpiece in the stove.Cooler is to be used for cooling off the waste gas that extracts from cup, and here EGT reduces.Flange-cooled appendix is used for the conveying of waste gas, can also further lower the temperature by fin simultaneously.Waste gas is by the back chamber of blast pipe importing stove at last, and the stove waste gas that is cooled mixes with the furnace gas stirring of heat under the stirring fan action of chamber, back, and the gas temperature reduction that circulates in stove and make the chamber, back, thereby makes the workpiece temperature reduction.Because the cup portion gas enters the chamber, back, make temperature reduction in the stove on the one hand, on the other hand because tolerance increases increased pressure, the hot gas of back chamber enters cup by middle dodge gate (promptly utilize the gap of dodge gate and doorframe or dodge gate is promoted certain altitude and form artificial gas passage), and the gas temperature of cup is raise.Enter the oil cooling wall (be oil cooling) of the gas of cup by cup a part of heat is taken away, gas temperature reduces.Gas continues cooling along quickly cooling device more then, enters the chamber, back, Zhou Erfu it, the circulation that does not stop like this can make afterwards that the workpiece temperature of chamber lowers with fast speeds.And the decline of the temperature of furnace lining is slower, and at this moment temperature of furnace lining is higher than workpiece temperature.When workpiece temperature dropped to the arts demand temperature, workpiece was moved cup to from the chamber, back, and at this moment furnace lining is also keeping higher temperature, thereby realized purpose energy-conservation and the shortening process time.
Therefore, the utility model Device for quickly cooling workpieces in heat treatment furnace 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.
