Description
Technical field
The present invention relates to a kind of drying oven, particularly a kind of smear metal drying oven.Belong to the drying oven to chip recycling recycling in mechanical processing industry.
Background technology
In machining, rapidoprint is generally adopted to first casting and forging molding, then carry out machining with metal cutting facility.In working angles, can produce a large amount of smear metals, these smear metals can refuse after recycling.More particularly contain the more material of precious alloy as nickelic magnesium iron, its nickel content reaches more than 30%, if valuable alloy resource has not only been saved in energy effective recycling, also can greatly reduce production costs.
Owing to will using cutting fluid in the process of in machining, rapidoprint being cut, in smear metal, all can be stained with like this cutting fluid.Enter melting furnace and dissolve if be stained with the smear metal of cutting fluid, the cutting fluid in smear metal is subject to evaporate after high temperature, and cutting agent Volatile Gas and steam etc. are wherein mixed into flue gas.Above-mentioned flue gas, to environment, also has harm to operating personnel's health.So will first dewater and drying and processing before smear metal enters melting furnace and dissolves.Dehydration can adopt precipitation or centrifugal process dehydration.Oven dry can be pressed into pie by the method for direct heating, drying or by smear metal or be deposited in container heating, drying again.While putting together due to scrap briquetting, can be squeezed into and pile piece, above-mentioned furnace drying method can heat smear metal piece top layer, but the difficulty of being heated in the middle of smear metal material piece, the cutting fluid in the middle of smear metal material piece is difficult to evaporate into flue gas discharge like this.Above-mentioned furnace drying method drying course is long, thermal energy consumption is large and drying effect is poor.
Summary of the invention
The object of the invention is for removing the custom-designed a kind of smear metal drying oven of cutting fluid in smear metal.In making smear metal constantly stir in stove and shake loose to unclamp, this drying oven dried by thermal-flame.In smear metal, all cutting fluids all can reach fast gasification and volatilization temperature and be vaporized and evaporate into gas.Its cutting fluid gas major part evaporating into that gasifies is fallen by high-temperature flame, can greatly reduce like this concentration of discharge flue gas.This drying oven also has advantages of that drying course is short, thermal energy consumption is little and good drying effect while drying smear metal material.
Technical scheme of the present invention is: a kind of smear metal drying oven.Support A, support B and drive unit are installed on grate.Drive unit sprocket wheel is housed on drive unit output shaft.Cylindrical furnace outer wall packaging has heat-insulation layer.Cylindrical furnace two ends are separately installed with round guide and bolster.A roller is respectively housed on two support A, and round guide sliding seat is contained on two rollers and can on roller, rolls.On support B, bearing is housed.Bolster is contained in bearing and can in bearing, rotates.Bolster outermost end is provided with bolster sprocket wheel.Chain is set on drive unit sprocket wheel and bolster sprocket wheel.Drive unit drives cylindrical furnace forward or reverse by drive unit sprocket wheel, chain and bolster sprocket wheel.On cylindrical furnace inwall, be welded with many blades by circumference equal dividing method, each blade is all clockwise direction.One end at the round guide of cylindrical furnace has feed inlet and outlet.The loading hopper being arranged on grate is arranged at feed inlet and outlet top, and charging spout is equipped with in the lower end of loading hopper, and charging spout lower end is stretched in cylindrical furnace.The shelves flitch that can open or close charging spout is installed between loading hopper and charging spout.Below body of heater feed inlet and outlet, be provided with blow tank, the feed inlet and outlet of blow tank upper end and cylindrical furnace is abutted against.Feed inlet and outlet outside is provided with range hood, and this range hood is fixed on grate.Range hood middle part has peep hole.Range hood top is provided with exhaust opening.Exhaust opening is connected with outside fume treatment auxiliary.Feed inlet and outlet middle part is provided with the flame jet pipe stretching in burner hearth.The gas pipeline being connected with flame jet pipe is connected with blast pipe all with one valve, and two valves are in order to regulation and control intake and combustion gas input.Flame jet pipe and gas pipeline and blast pipe are arranged on the holder of peep hole.
Operation principle of the present invention and process are: start drive unit and make the rotation of body of heater counter-clockwise direction smear metal be passed through to loading hopper simultaneously, charging spout is sent in body of heater.Once add the quantity of smear metal to determine according to burner hearth size.Then after the valve of opening on gas pipeline and blast pipe, in air feed air feed in burner hearth, light flame playpipe.After smear metal band being played to certain altitude in now blade is pushed in burner hearth by smear metal in rotary course, fall from blade again, enter like this smear metal in stove and in burner hearth, constantly stir up and down and become block smear metal to be shaken up and scatter stirring in process.The farthest thermally equivalent of smear metal scattering of being shaken up, these constantly stir and shaken loose the smear metal of unclamping up and down, and under the burning baking of high-temperature fuel gas, it sticks to that cutting fluid in smear metal reaches the temperature of cutting fluid gasification and volatilization very soon and by Volatile Gas formation gas.The gas that these Volatile Gas change under the thermal-flame of flame playpipe ejection most of burned fall.So just greatly reduce the concentration of discharging flue gas.The gas of small part volatilization gasification is delivered to outside fume treatment auxiliary with flue gas from the exhaust opening of range hood and is for further processing.Smear metal in burner hearth under the burning baking of high-temperature fuel gas by flash baking.After smear metal is by flash baking, closing valve on gas pipeline and blast pipe stops to air feed air feed in burner hearth.Switching driving device pole changer rotates body of heater clockwise simultaneously, and the now smear metal in body of heater is pushed to feed inlet and outlet place and enters blow tank by blade.Being admitted to next procedure from blow tank smear metal is out for further processing.This smear metal drying work completes.Repeat above-mentioned work and can continuously carry out drying and processing to smear metal.
Advantage of the present invention is for removing the custom-designed a kind of smear metal drying oven of cutting fluid in smear metal.In making smear metal constantly stir in stove and shake loose to unclamp, this drying oven dried by thermal-flame.In smear metal, all cutting fluids all can reach fast gasification and volatilization temperature and be vaporized and evaporate into gas.Its cutting fluid gas major part evaporating into that gasifies is fallen by high-temperature flame.Greatly reduce like this concentration of discharge flue gas.This drying oven also has advantages of that drying course is short, thermal energy consumption is little and good drying effect while drying smear metal material.
