Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model material conveying device;
Fig. 2 is the structural representation of the utility model power transmission.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, 2, a kind of high temperature process furnances automatically, comprises material conveying device and power transmission.
Described material conveying device is provided with discharge nozzle 1, heating tube 4 and conveying pipeline 6; described discharge nozzle 1 and heating tube 4 and all connected by connector 2 between heating tube 4 and conveying pipeline 6; described heating tube 4 is positioned at diamond heating body 3; described conveying pipeline 6 is provided with reducing gases, protection gas air inlet 5 and charging aperture 7, and described conveying pipeline 6 is positioned at cover near charging aperture 7 push rod 8.The number of described reducing gases, protection gas air inlet 5 is 2, after putting into crucible through charging aperture 7, pass into gas to reducing gases, protection gas air inlet 5.The diameter of described charging aperture 7 is greater than the diameter of the crucible holding material.
Described power transmission comprises slide block 9, screw mandrel slide unit 10, guide rail 11, screw mandrel 12 and motor 13, the centre of described screw mandrel slide unit 10 is provided with screw mandrel 12, described motor 13 is connected with screw mandrel 12, and motor 13 drives screw mandrel 12 to rotate, and described screw mandrel slide unit 10 two ends are provided with guide rail 11, described slide block 9 is placed on screw mandrel slide unit 10 with screw mandrel 12 in vertical angle, and described slide block 9 is fixedly connected with push rod 8.
In use; the a collection of crucible holding material is put into charging aperture 7; pass into gas to reducing gases, protection gas air inlet 5 simultaneously; to make sample calcination in suitable atmosphere; a segment distance is pushed away before crucible is slow by push rod 8; the crucible of final front end will move to the high-temperature region of heating tube via heating zone, and push rod 8 returns original place.After the crucible heat insulation time of front end completes, some crucibles are put into again to charging aperture 7, push away before it with push rod 8, make second batch crucible move to high-temperature region, push rod 8 is recalled, after temperature retention time completes, put into some crucibles to charging aperture 7 again, so repeatedly carry out, finally realize the continuous sintering of sample in crucible, simultaneously under the promotion of crucible below, first batch of crucible arrives the discharging mouth of pipe 1, and the sample sintered is come out of the stove smoothly.Thus realize continuous feed, add the efficiency of tube furnace.
The time that push rod 8 moves and speed are controlled by single shaft stepper motor 13, and this device includes slide block 9, screw mandrel slide unit 10, guide rail 11, screw mandrel 12, motor 13.Motor 13 provides power, motor 13 is connected with screw mandrel slide unit 10, motor 13 work strip movable wire bar 12 rotates, under the rotation of screw mandrel 12, drive the slide block 9 on guide rail 11 to move forward and backward, because push rod 8 is fixed on slide block 9, therefore, push rod 8 also just seesaws thereupon, so the time that push rod 8 is movable and speed are determined by the setting of motor 13.
The utility model is can not the improvement of continuous feeding and discharging to conventional tubular stove, and a series of crucible filling sample is put into conveying pipeline from charging aperture, and the quantity putting into crucible is full of carrier pipe until front end, heating tube high-temperature region.When motor is opened, because push rod is fixed on slide block, therefore push rod also just seesaws thereupon, under the effect of push rod, from the crucible filling sample that charging aperture is put into, slowly will move forward under the effect of push rod, a crucible of final front end will move to the high-temperature region of boiler tube foremost via heating zone, and now push rod returns original place.After the crucible heat insulation time of front batch completes, a collection of crucible is put into again to charging aperture, push away before it with push rod, make second batch crucible move to high-temperature region, push rod is recalled, after temperature retention time completes, a collection of crucible is put into again to charging aperture, so repeatedly carry out, thus realize continuous feed, which adds the production efficiency of tube furnace.
For those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
