In this embodiment, the first lifting assembly 210 includes a lifter 211, a clamping cylinder 212, a lifting and conveying roller shaft 213, and a lifting and conveying motor 214 for driving the lifting and conveying roller shaft 213 to rotate, the lifter 211 is used for driving the clamping cylinder 212, the lifting and conveying roller shaft 213, and the lifting and conveying motor 214 to synchronously lift, and the clamping cylinder 212 is used for clamping the crucible 500 on the lifting and conveying roller shaft 213 to prevent the crucible 500 from falling. The second lifting assembly 220 is identical in structure to the first lifting assembly 210. Before blanking, the lifting and conveying roller shaft 213 of the first lifting assembly 210 is used for conveying the crucible 500 thereon to the blanking conveying roller shaft 231, and after blanking, the second lifting assembly 220 lifts the conveying roller shaft 213 for conveying the crucible 500 thereon to the conveying roller shaft 310 of the feeding and conveying mechanism 300.

In this embodiment, the sintering apparatus 600 comprises a main kiln 610 and a secondary kiln 620, wherein the inlet of the secondary kiln 620 is connected with the feeding conveying mechanism 300 through a push plate mechanism 650, the outlet is connected with the main kiln 610 through a feeding pushing system 630, and the outlet of the main kiln 610 is connected with the discharging conveying mechanism 400 through a discharging pushing system 640.

The working principle is as follows:

as shown in FIG. 10, the empty crucible 500 is conveyed to the charging station 101 via the conveying roller 310 for charging. After the crucible 500 is accurately positioned above the weighing module 700 of the feeding station 101, the jacking assembly 710 jacks up the empty crucible 500, so that the crucible 500 is separated from the conveying roller shaft 310, and weighing is facilitated;

after the crucible 500 rises, the weighing module 700 starts to work, the weights of the crucible 500 and the jacking assembly 710 are cleared firstly, only the weight of raw material balls is called, and the raw material balls stored in the bin 120 are placed into the crucible 500 by the vibrating feeder 130. The vibratory feeder 130 is preset with a fast mode and a slow mode, when the weighing module 700 weighs the raw material balls with weight far lower than the set weight, the vibratory feeder 130 starts the fast feeding mode, when the weighed weight is close to the set weight, the slow feeding mode is started to prevent the blanking speed from being too fast, the weight of the raw material balls in the crucible 500 overshoots and is higher than the set value, when the weighing module 700 weighs the raw material balls with weight equal to the set weight, the vibratory feeder 130 stops blanking, the jacking assembly 710 descends, the crucible 500 is placed back on the conveying roller shaft 310, and the crucible 500 continues to advance on the conveying roller shaft 310;

when the crucible 500 reaches the inlet of the auxiliary kiln 620, the crucible is pushed into the auxiliary kiln 620 through the push plate mechanism 650, after the auxiliary kiln 620 is preheated, the crucible is pushed into the main kiln 610 through the feeding push system 630 to be sintered, most pellets are bonded together to form a whole block after the vanadium-nitrogen alloy pellets are sintered, and the crucible 500 is sent out to the conveying roller shaft 310 of the discharging conveying mechanism 400 through the discharging push system 640;

the discharging transfer roller 310 transfers the crucible 500 to the elevation transfer roller 213 of the first elevation assembly 210. Because the whole charging crucible 500 is turned over during charging, finished vanadium-nitrogen alloy in the crucible 500 naturally falls into the movable charging barrel 800 below, the original conveying horizontal plane is too low to meet the height requirement of turning, and the working horizontal plane of the charging device is improved and is about twice as high as the original conveying horizontal plane. The first lifting assembly 210 lifts the crucible 500 filled with finished vanadium-nitrogen alloy to the blanking conveying roller shaft 231, the crucible 500 moves forward on the blanking conveying roller shaft 231, enters the overturning roller shaft 242, stops when touching the baffle 2451, at the moment, the clamping plate 2431 clamps the crucible 500, the pressing plate 2433 presses the crucible 500, the overturning motor 241 drives the whole body to overturn 180 degrees, the finished vanadium-nitrogen alloy in the crucible 500 falls into the movable receiving barrel 800, then when the crucible returns to overturn, the driving cylinder 2453 drives the baffle 2451 to overturn downwards anticlockwise, the blockage is removed, the empty crucible 500 continues to move forward, the crucible 500 enters the lifting conveying roller shaft 213 of the second lifting assembly 220, and the second lifting assembly 220 lowers the emptied crucible 500 which is poured to the feeding conveying roller shaft 310.

The feeding conveying roller shaft 310 conveys the empty crucible 500 to the feeding station 101 for the next feeding operation.

The first lifting assembly 210 in front of the blanking conveying assembly 230 lifts the crucible 500 filled with the finished vanadium-nitrogen alloy from the conveying device level to the working level of the blanking device, and the second lifting assembly 220 behind the blanking conveying assembly 230 lowers the empty crucible 500 filled with the finished vanadium-nitrogen alloy from the blanking working level to the conveying level so as to continuously convey the empty crucible 500 to the feeding mechanism 100 for charging.

The feeding conveying roller shaft 310 and the discharging conveying roller shaft 310 have the same structure and are mainly used for connecting the feeding mechanism 100 and the discharging mechanism 200, so that the crucible 500 can smoothly move between feeding and discharging.
