A material silo 2, B material silo 3, vacuum pump 4, storage tank 5 and material receiving piece are installed on the support frame 1. A material silo 2 is located next to the vacuum pump 4, B material silo 3 is located above the vacuum pump 4, storage tank 5 is located above B material silo 3, and the material receiving piece is located between B material silo 3 and storage tank 5. B material silo 3 is used to discharge materials to the material receiving piece. The materials in the material receiving piece are discharged through the material taking mechanism. Transferred to the tempering furnace, a discharge pipe connected to the B silo 3 is provided at the bottom of the storage tank 5, and a valve is installed on the discharge pipe. The vacuum pump 4 discharges the air in the storage tank 5 through the A pipe 6, and the material in the A silo 2 is transported to the storage tank 5 through the B pipe 7. After the raw materials are added to the A silo 2, the air in the storage tank 5 is discharged through the vacuum pump 4. At this time, the negative pressure in the storage tank 5 sucks the raw materials in the A silo 2 through the B pipe 7, and then the valve is opened to allow the raw materials to enter the B silo 3 for quantitative discharge into the material barrel 11, and then added into the tempering furnace through the material taking mechanism, which reduces the labor intensity of workers and improves personal safety.

[0027] In this embodiment, if Figure 2 , 56, the material receiving part includes a workbench 8, a turntable 9 and a stepper motor 10. The workbench 8 is installed in the support frame 1, and the turntable 9 is rotatably installed on the workbench 8. The stepper motor 10 is fixed at the bottom of the workbench 8. The stepper motor 10 is used to drive the turntable 9 to rotate. A plurality of barrels 11 are arranged on the turntable 9. The barrels 11 are evenly distributed around the center of the turntable 9. The barrels 11 are used to receive the discharge of the B silo 3. The materials in the barrels 11 are transferred to the tempering furnace through the material taking mechanism. A countersunk through hole 19 is provided on the workbench 8, and the countersunk through hole 19 is used to place the material barrel 11 to prevent the material barrel 11 from not being placed in the set position, resulting in the material barrel 11 not entering the discharge area of ​​the B silo 3 after the A stepper motor 10 rotates, thereby causing the material to be scattered outside the material barrel 11. In order to facilitate the material taking mechanism to deliver the material barrel 11 to the tempering furnace, a lifting cylinder 20 is fixed on the side wall of the workbench 8 close to the tempering furnace, and the material barrel 11 close to the tempering furnace is lifted away from the countersunk through hole 19 by the lifting cylinder 20.

[0028] In this embodiment, if Figure 3 and 4 As shown, the material taking mechanism includes a base 12, a claw clamp cylinder 13, a rotating cylinder 14 and a B stepping motor 15.

A vertical electric cylinder 17 is fixed on the slide of the A screw guide rail slide 16. A support seat 18 is fixed on the piston rod of the electric cylinder 17. The B stepping motor 15 is fixed on the support seat 18. The rotating cylinder 14 and the claw clamp cylinder 13 are both installed on the rotating shaft of the B stepping motor 15. The rotating cylinder 14 is used to rotate the claw clamp cylinder 13. The claw clamp cylinder 13 is used to clamp the material barrel 11 close to the tempering furnace. A bearing platform 21 is fixed in the support frame 1. The bearing platform 21 is used to slide the workbench 8 , the sliding end of the workbench 8 is close to the tempering furnace. When the workbench 8 is at the starting end, the cooperation between the turntable 9 and the B silo 3 allows each barrel 11 to be filled with raw materials. When the barrel 11 is full, the workbench 8 moves to the end. At this time, part of the barrel 11 on the turntable 9 is located outside the bracket, and the claw clamp cylinder 13 is moved to the middle of the barrel 11 through the electric cylinder 17, avoiding interference between the bracket and the claw clamp cylinder 13 when clamping the barrel 11, affecting the clamping of the barrel 11. When taking the material, the negative pressure of the vacuum pump is used to push the powder into the storage tank through the pipeline. A screw is provided in the storage tank. After the material is stirred by the screw and discharged into the barrel and weighed, the manipulator clamps it, flips it and pours it, thereby adding a certain amount of powder to the four corners of the tempering furnace containing the high-temperature potassium nitrate solution.

[0029] In this embodiment, if Figure 1As shown, a horizontally movable B-screw guide rail slide 22 is also installed on the side wall of the base 12 close to the tempering furnace. A feeding hopper 23 is fixed on the slide of the B-screw guide rail slide 22. A ball valve is installed at the discharge end of the feeding hopper 23.
