A protrusion 37 is fixedly installed on the inner wall of the mixing tube 36, and the protrusion 37 is located in the slide groove 52 and is slidably connected to the slide groove 52. The circulation tube 49 is provided with a sixth conduit 48 and a fourth conduit 32 connected to the interior thereof. The fourth conduit 32 and the sixth conduit 48 are both located on the side of the square circulation plug 51 away from the round rod 53. A refrigeration box 47 is provided on the outer wall of the rotating block 29. A cooling chamber 31 located outside the groove 35 is opened on the rotating block 29. One end of the sixth conduit 48 away from the circulation tube 49 is connected to the refrigeration box 47, and one end of the fourth conduit 32 away from the circulation tube 49 is connected to the cooling chamber 31.

A discharge port 38 is provided at the bottom of the circular shell 9, and the slide groove 52 is wavy.

[0030] When the present invention is used, in the initial position, the groove 35 is located in a position aligned with the feed opening 38, the gear 54 is not engaged with the incomplete gear ring 50, and the movable energizing rod 19 is located between the cylinder 18 and the first oil cylinder 20. Figure 3 , Attachment Figure 4 and attached Figure 6 As shown, the motor 3 is then started to rotate the shaft 30, the rotating block 29, the cam 17 and the movable energizing rod 19 clockwise (see FIG. Figure 2 During the first clockwise rotation of the shaft 30, the rotating block 29, the cam 17 and the movable energizing rod 19 by 90 degrees, the movable energizing rod 19 will first contact the cylinder 18 and cause the cylinder 18, the square rod 39 and the driving plug 40 to move to the left (see Figure 1). Figure 4 state) for a distance, the first spring 41 is compressed, and then the movable energizing rod 19 is no longer in contact with the cylinder 18, and the elastic force generated by the compression of the first spring 41 can make the driving plug 40 move rightward and return to the initial position;

[0031] When the driving plug 40 moves to the left, the incompressible oil in the second oil cylinder 22 is sucked into the first oil cylinder 20 through the third conduit 21, so that the feed plug 26 moves to the right (see FIG. Figure 3 state), by setting a discharge rod 25, the discharge plate 5 can be moved to the right, so that the discharge hole 7 is aligned with the bottom opening of the feed hopper 4, and the petroleum coke raw material in the feed hopper 4 will fall into the calcining cylinder 27 through the discharge hole 7. When the driving plug 40 moves to the right and returns to the initial position, the discharge plug 26 will slide to the left and return to the initial position, so that the discharge plate 5 can move to the left so that the discharge hole 7 is no longer aligned with the bottom opening of the feed hopper 4, so that automatic quantitative discharge can be achieved;

[0032] When the movable energizing rod 19 and the cylinder 18 are no longer in contact with each other and continue to rotate, the movable energizing rod 19 will contact the fixed energizing rail 15, so that the electric box 24 energizes the heat collecting plate 43 through the connecting line 42, and the heat collecting plate 43 generates heat energy in the inner cavity 28 and converts the petroleum coke raw material into carbon;

[0033] When the rotating shaft 30, the rotating block 29, the cam 17 and the movable energizing rod 19 rotate clockwise by 90 degrees for the second time, the movable energizing rod 19 is no longer in contact with the fixed energizing rail 15, and the cam 17 causes the lower plate 16, the connecting rod 14 and the upper plate 10 to move upward, and the second spring 44 is compressed. During the upward movement of the upper plate 10, the gas collecting rod 45 is provided to enable the gas collecting plug 46 to move upward, so that the gas generated by calcination in the calcination tube 27 can be sucked into the gas collecting tube 11 through the first conduit 6. When the rotating shaft 30, the rotating block 29, the cam 17 and the movable energizing rod 19 rotate clockwise by 90 degrees for the second time, the groove 35 is aligned with the bottom opening of the calcination tube 27, so that the carbon generated by calcination falls into the groove 35;

[0034] When the rotating shaft 30, the rotating block 29, the cam 17 and the movable energizing rod 19 rotate clockwise for the third time by ninety degrees, the elastic force generated by the compression of the second spring 44 can make the lower plate 16, the connecting rod 14 and the upper plate 10 move downward, and the gas collecting rod 45 is provided to make the gas collecting plug 46 move downward, so that the gas sucked into the gas collecting cylinder 11 can be squeezed into the gas collecting box 8 through the second conduit 12, so as to collect the gas after calcination. At the same time, during this process, the gear 54 and the incomplete gear ring 50 are meshed with each other, so that the stirring tube 36 and the protrusion 37 rotate. Since the square circulation plug 51 will not rotate around the axis of the stirring tube 36 and the protrusion 37 is located in the slide groove 52, the protrusion 37 will slide in the wavy slide groove 52, so that the square circulation plug 51 can reciprocate left and right in the circulation cylinder 49 (see Appendix). Figure 5 When the square circulation plug 51 reciprocates left and right, the cooling water in the refrigeration box 47 is sucked into the circulation drum 49 through the sixth conduit 48, and then squeezed into the cooling chamber 31 through the fourth conduit 32. At the same time, the cooling water in the cooling chamber 31 that has partially absorbed heat is squeezed into the refrigeration box 47 through the fifth conduit 33 for cooling again. This reciprocating process allows the cooling water to circulate in the refrigeration box 47, the circulation drum 49 and the cooling chamber 31, and the carbon in the groove 35 is continuously cooled. The rotation of the stirring tube 36 also drives the stirring rod 34 to rotate, thereby stirring the carbon in the groove 35, thereby improving the cooling effect.

[0035] When the rotating shaft 30, the rotating block 29, the cam 17 and the movable energizing rod 19 rotate clockwise by ninety degrees for the fourth time, the groove 35 will be aligned with the discharge port 38 again, so that the carbon in the groove 35 will fall through the discharge port 38 for collection (the collecting device is not shown), and at the same time, the gear 54 and the incomplete gear ring 50 will no longer mesh with each other, and such reciprocating operation enables continuous calcination conversion.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
