Description
Technical field
The invention belongs to high temperature ovens.The present invention produces the fusing stove of polyol masses technique be applicable to polyurethane.
Background technology
Polyhydric alcohol is the main material that polyurethane produces in technique, and under room temperature, polyhydric alcohol is solid forms, produces at polyurethane
In raw technique, need to input in reactor by polyhydric alcohol, it is necessary to solid polyalcohol is molten into liquid form, is then sent by pumping
In reactor, so, the liquefaction of polyhydric alcohol is the important process during polyurethane produces.At present, the liquefaction work of polyhydric alcohol
Skill typically uses to be put into barreled solid polyalcohol in electrothermal high-temperature stove or steam high temperature furnace, utilizes electrothermal high-temperature or steam high temperature
Solid polyalcohol is molten into liquid polyol.Its major defect is: electrothermal high-temperature stove power consumption is big, and processing cost is high；Steam
Though the low cost of high temperature furnace unit interval, for medium-sized and small enterprises, steam boiler general daytime opens, if at night in order to
Steam high temperature furnace is provided separately steam, and its cost is also greater than muffle electric furnace.
Summary of the invention
It is an object of the invention to the shortcoming existed for prior art, it is provided that the polyurethane that a kind of polyhydric alcohol melting cost is low
Polyhydric alcohol high-temperature melting furnace.
Technical scheme includes body of heater, and body of heater is that the heat insulation wall closed is constituted, at body of heater inner chamber both sides body of wall
Upper setting adds heat pipe；Mainly adding heat pipe to be made up of electric heating tube and steam-heating pipe, steam-heating pipe passes through electrically-controlled valve and steaming
Boiler furnace connects, and electric heating tube power supply uses coordinated signals on-off control with electrically-controlled valve power supply；Described coordinated signals switch uses
Control relay circuit, the normally open contact of control relay circuit is serially connected in electrically-controlled valve power circuit, control relay circuit
Normally closed interlock be serially connected in electric heating tube power circuit, in electric heating tube power circuit install main switch.
Preferably, concatenating temperature detect switch (TDS) in electric heating tube power circuit, this temperature detect switch (TDS) is entered by being arranged on steam-heating pipe
The temperature sensor of mouth controls, and when in steam-heating pipe, temperature is more than 110 °, temperature sensor controls temperature detect switch (TDS) and is in disconnected
Open state.
Preferably, installing blower fan at body of heater top, electric heating tube and steam-heating pipe are arranged in fan air channel.
It is an advantage of the invention that adding heat pipe is made up of electric heating tube and steam-heating pipe, use during boiler steam supply by day and steam
Vapour heats, and when evening, boiler stopped vapour, electricity consumption is at a low ebb, uses electrical heating, saves the energy, reduces polyhydric alcohol melting process
Production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Polyurethane polyol high-temperature melting furnace as shown in Figure 1, including body of heater 1, body of heater 1 is the heat insulation wall structure closed
Become, body of heater 1 inner chamber both sides body of wall is arranged and adds heat pipe；Add heat pipe to be made up of electric heating tube 2 and steam-heating pipe 3, electrical heating
Pipe 2 is arranged on the top of body of heater 1 inner chamber both sides body of wall, and steam-heating pipe 3 is arranged on the bottom of body of heater 1 inner chamber both sides body of wall, steams
Vapour is added heat pipe 3 and is connected with steam boiler by electrically-controlled valve, when steam boiler is in steam supply state, opens electrically-controlled valve and adds steam
Heat pipe 3 steam supply, electric heating tube 2 power supply uses coordinated signals on-off control with electrically-controlled valve power supply；Described coordinated signals switch uses
Control relay circuit, the normally open contact of control relay circuit is serially connected in electrically-controlled valve power circuit, control relay circuit
Normally closed interlock be serially connected in electric heating tube 2 power circuit, use steam-heating pipe 3 steam supply time, relay power control of closing
Switch, makes relay coil obtain electric, and its normally open contact Guan Bi, normally closed interlock disconnect, and electrically-controlled valve is opened, and electric heating tube 2 power supply breaks
Opening, boiler is to steam-heating pipe 3 steam supply, and when disconnecting relay power control switch, its normally open contact and normally closed interlock reset, electricity
Control valve cuts out, and the energising of electric heating tube 2 power supply begins to warm up, and installs main switch in electric heating tube 2 power circuit, stops at fusing stove
Main switch is disconnected during work.
Concatenating temperature detect switch (TDS) in electric heating tube 2 power circuit, this temperature detect switch (TDS) is by the temperature being arranged on steam-heating pipe 3 import
Degree sensor controls, and when in steam-heating pipe 3, temperature is more than 110 °, the control signal of temperature sensor controls temperature detect switch (TDS) and breaks
Open, and when temperature drops to 110 ° in steam-heating pipe 3, the control signal of temperature sensor controls temperature detect switch (TDS) Guan Bi.At steam
Adding heat pipe 3 and stop the steam supply initial stage, fusing stove utilizes steam waste heat to work, and when vapor (steam) temperature drops to 110 °, temperature detect switch (TDS) closes
Opening electric heating tube 2 to heat fusing stove, i.e. when steam-heating pipe 3 quits work, electric heating tube 2 delay path works, and prolongs
Time time by temperature sensor control, be from steam-heating pipe 3 quit work to fusing in-furnace temperature drop to 110 ° time
Time, make full use of steam thermal energy.This time delay is opened the control circuit of electric heating tube 2 power supply and computer can be used to automatically control
Circuit, has a variety of control circuit to realize, belongs to known technology.
Install blower fan 4 at body of heater 1 top, electric heating tube 2 and steam-heating pipe 3 are arranged in the air channel 5 of blower fan 4.Blower fan 4
The even heat of electric heating tube 2 or steam-heating pipe 3 is distributed at fusing furnace chamber.
Body of heater 1 bottom surface is provided with the wheel road placing many go-carts 6.
