Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to an expanded graphite desulfurizer. Background Art

[0002] Natural graphite is often contaminated by sulfur impurities during the acidification and expansion process, especially in expansion furnaces heated by natural gas or diesel. If the large amount of sulfur-containing gas produced by the combustion of the fuel is not removed, the sulfur impurities in the graphite worms will be greatly increased, which will seriously affect the quality of graphite paper.

[0003] The prior art reference announcement number CN208038054U discloses an expanded graphite desulfurizer, which mixes a desulfurizer and graphite with sulfur dioxide, and simultaneously achieves an up and down oscillation effect through the overall structure, thereby ensuring that the graphite with sulfur dioxide can contact the desulfurizer more evenly. However, the graphite doped with sulfur dioxide has a certain volume and hardness. If it is not crushed, it is difficult to quickly and comprehensively contact with the desulfurizer, especially the mixing efficiency and degree will be greatly reduced, seriously affecting the desulfurization effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 An expanded graphite desulfurizer includes a chassis 1, in which an upper cavity 101, a middle cavity 102 and a lower cavity 103 are provided, and a load-bearing bracket 2 is fixedly installed at the top position of the chassis 1. The chassis 1 is provided with a driving motor 3 and a driving worm 4 driven to rotate by the driving motor 3 through the load-bearing bracket 2, and the two are connected by a transmission belt. The chassis 1 is provided with a container barrel 5 for loading graphite through the upper cavity 101. It should be noted that the container barrel 5 is a cylindrical tube structure with uniform holes at the bottom end. Under the transmission action of the driving worm 4, the container barrel 5 is rotated to avoid the accumulation of sulfur-containing graphite and desulfurizer in the container barrel 5.

[0023] The chassis 1 is provided with a mixing mechanism for mixing sulfur-containing graphite and desulfurizing agent through a driving worm 4 and a container barrel 5:

[0024] On the one hand, the mixing mechanism includes a transmission worm wheel 6 fixedly mounted on the container barrel 5 and meshingly connected to the driving worm 4, and the driving worm 4 is fixedly connected with a traction turntable 7 at both ends, a guide groove 8 is opened in the outer wall of the chassis 1, and a guide block 9 movably pulled by the traction turntable 7 is slidably sleeved in the guide groove 8. During the rotation process of the traction turntable 7, the guide block 9 is driven by the first connecting rod 10 to reciprocate and lift in the guide groove 8. A lifting frame 11 is integrally connected to the guide block 9, and the lower end of the lifting frame 11 is integrally connected to a supercharging plate 12 located in the container barrel 5. Refer to the attached manual Figure 2 The pressurizing plate 12 is a semi-circular disc structure with half of the container barrel 5 open, so as to facilitate the introduction of sulfur-containing graphite and desulfurizing agent into the container barrel 5;

[0025] On the other hand, the mixing mechanism also includes a telescopic rod 13 which is slidably sleeved in the middle cavity 102 and movably pulled by the guide block 9, and the telescopic rod 13 is integrally connected with a grinding plate 14 located in the middle cavity 102. Figure 2It should be noted that the connecting hole between the upper cavity 101 and the middle cavity 102 is opened at the peripheral position, and the connecting hole between the middle cavity 102 and the lower cavity 103 is opened at the central position, which is convenient for grinding the sulfur-containing graphite during the horizontal movement of the grinding plate 14, and at the same time, the sulfur-containing graphite and the desulfurizer are pushed in reverse. A central pipe 16 connecting the upper cavity 101 and the lower cavity 103 is fixedly installed in the middle cavity 102, and a stirring shaft 17 extending into the lower cavity 103 through the central pipe 16 is integrally connected to the lower end of the container barrel 5. The stirring shaft 17 in the central position stirs and drives the sulfur-containing graphite and the desulfurizer falling from the central position to achieve uniform distribution of the sulfur-containing graphite and the desulfurizer in the lower cavity 103, ensuring sufficient and uniform mixing.

[0026] The upper cavity 101 , the middle cavity 102 and the lower cavity 103 are distributed from top to bottom in the chassis 1 , and the upper cavity 101 and the lower cavity 103 are connected through the middle cavity 102 , so that the sulfur-containing graphite and the desulfurizer can move from the upper cavity 101 to the lower cavity 103 .

[0027] The chassis 1 is opened at the top of the upper cavity 101 to facilitate the setting of a container barrel 5 extending out of the upper cavity 101, and the bottom of the chassis 1 is provided with a discharge port connected to the lower cavity 103 to facilitate the discharge of clean graphite after desulfurization to the outside of the chassis 1.

[0028] The driving motor 3 is fixedly mounted on the load-bearing bracket 2 , and the driving worm 4 is rotatably mounted at the top opening position of the chassis 1 through the load-bearing bracket 2 .

[0029] An eccentrically arranged first connecting rod 10 is pin-connected on the traction turntable 7, and the first connecting rod 10 is pin-connected to the guide block 9. A second connecting rod 15 is pin-connected between the guide block 9 and the telescopic rod 13. During the rotation of the traction turntable 7, the guide block 9 reciprocates up and down due to the height difference and position difference, and the lifting frame 11 and the telescopic rod 13 are synchronously pulled by the guide block 9.

[0030] It should be noted that the specific model and specifications of the drive motor 3 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] Put the sulfur-containing graphite and the desulfurizing agent into the container barrel 5, and control the driving motor 3 to start;

[0033] The output end of the driving motor 3 drives the driving worm 4 to rotate, and the driving worm 4 drives the container barrel 5 to rotate through the transmission worm wheel 6;

[0034] The driving worm 4 drives the traction turntable 7 to rotate, and drives the guide block 9 to move up and down in the guide groove 8 through the first connecting rod 10. The guide block 9 drives the booster plate 12 to move up and down in the container barrel 5 through the lifting frame 11, so as to preliminarily pressurize and crush the sulfur-containing graphite, so that the sulfur-containing graphite and the desulfurizer enter the middle cavity 102;

[0035] The guide block 9 pulls the telescopic rod 13 through the second connecting rod 15, so that the grinding plate 14 is horizontally extended and retracted in the middle cavity 102 to further grind and crush the sulfur-containing graphite and the desulfurizing agent, so that they enter the lower cavity 103 from the center position;

[0036] The container barrel 5 drives the stirring shaft 17 to rotate in the lower cavity 103 to further stir and drive the falling sulfur-containing graphite and the desulfurizing agent so that the two are fully mixed.

[0037] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
