For achieving the above object, the technical solution used in the present invention is: a kind of continuous tunnel furnace, comprises upper furnace body, lower furnace body, entersAir port, air outlet, and blower fan, wherein go up employing bolted on connection between lower furnace body, and upper and lower body of heater is hollow, hollow spaceFill asbestos heat-barrier material, described continuous tunnel furnace inside is provided with resistive heater or Far infrared heating plate, and upper furnace body top sets outAir port, lower furnace body bottom arrange air inlet, and fan outlet is with air inlet to connection, and assembling is in frame, and continuous tunnel furnace is tool alsoThere is movable fixture.
The invention has the beneficial effects as follows:
Because the present invention adopts electrical heating wire or heating plate energising heating, heat energy transfers to rapidly body of heater inside, fan starting, edgeBody of heater inside and upwards carry, form high-temperature hot-air, thereby reach sintering temperature, complete the sintering process of relative article, pass throughMobile device can be realized the movement of continuous tunnel furnace.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made to brief description.
A kind of continuous tunnel furnace, comprises blower fan 1, frame 2, body of heater 3, and wherein body of heater 3 can be divided into upper furnace body and lower furnace body, upper and lower stoveEmploying bolted on connection between body. Upper furnace body top sets out air port, lower furnace body bottom arranges air inlet, and fan outlet is with enteringAir port is to connection. Assembling is in frame. Mobile device is arranged on frame bottom.
Upper and lower furnace binding is designed to the form of the cotton insulation material of horsestone between two-layer template. Upper and lower body of heater outer and inLayer all adopts 5mm cold-rolled steel sheet, and punch forming, is mingled with insulation material therein.
Body of heater inside is provided with heater, and heater is electrical heating wire or heating plate.
Continuous tunnel furnace also comprises a Control for Kiln Temperature unit, is arranged on continuous tunnel furnace outside. Insert to continuous tunnel furnace is inner by air outletEnter a thermocouple to provide control data to Control for Kiln Temperature unit, thermocouple is connected with a data acquisition unit, will be in tunnelThe temperature change that furnace interior occurs just can be recorded with required sampling frequency, then signal is passed to Control for Kiln Temperature listUnit, Control for Kiln Temperature unit regulates heater as requested, and then furnace temperature is regulated.
Wherein Control for Kiln Temperature unit has corresponding circuit arrangement, and described circuit arrangement has main circuit board, wherein main electricityOn the plate of road, be integrated with single-chip microcomputer, switching input module, RS485 communication module, infrared remote control receiver module, USB module, power amplifierModule and memory module;
Single-chip microcomputer has switching value input, 485 signal input parts, infrared signal input, usb communication end, thermocouple controlEnd, furnace temperature circuit control end and storage data communication end; Switching input module has input and output; RS485 communicationModule has input and output; Infrared remote control receiver module has signal output part; USB module has USB interface and letterNumber output; Power amplifier module has control signal input and signal output part; Memory module has data terminal; Thermocouple hasSignal input part; Heater has control signal input;
The switching value input of single-chip microcomputer is electrically connected with the output of switching input module; 485 signal input parts of single-chip microcomputerBe electrically connected with the output of RS485 communication module; The infrared signal input of single-chip microcomputer and the signal of infrared remote control receiver moduleOutput electrical connection; The usb communication end of single-chip microcomputer is electrically connected with the signal output part of USB module; The power amplifier control end of single-chip microcomputerBe electrically connected with the control signal input of power amplifier module; The storage data communication end of single-chip microcomputer and the data terminal of memory module are two-wayCommunication electrical connection; The thermocouple circuit control end of single-chip microcomputer is electrically connected with the control signal input of heater circuit board; MeritThe signal output part of amplification module is electrically connected with the signal input part of heater.
Described mobile device comprises chute 5, cover plate set bolt 6, and guide rail 7, pressing plate set bolt 8, mount pad 9, installsBolt 10, frame construction bolt 11, dog screw 12, cover plate 13. Its center platen compresses guide rail 7 by pressing plate set bolt 8On mount pad 9, mount pad 9 is fixed on base or floor by construction bolt 10, between guide rail 7 and chute 5, is provided with rollingBearing, chute 5 can slide on guide rail 7, and chute 5 is provided with cover plate 13, and cover plate 13 is angle steel shape, and cover plate 13 is consolidated by cover plateDetermine bolt 6 and be connected with chute 5, be also provided with frame construction bolt 11 on cover plate 13, frame construction bolt 11 is by 13 months machines of cover plateFrame 2 is connected, and in the time that chute 5 slides along guide rail 7, can drive cover plate 13 to slide, and then drives whole frame 2 to slide, finalDrive the slip of whole body of heater, in the time that body of heater slides into the position needing, by turn-knob dog screw 12, dog screw 12 passesThrough hole on cover plate and chute, so with guide rail 7 Surface Contacts, thereby complete location.
Above one embodiment of the present of invention are had been described in detail, but described content is only better enforcement of the present inventionExample, can not be considered to for limiting practical range of the present invention. All equalizations of doing according to the present patent application scope change and improveDeng, within all should still belonging to patent covering scope of the present invention.
