Description

Technical Field

[0001] The utility model relates to the technical field of raw material processing of carbon molecular sieves, in particular to a carbon molecular sieve raw material crushing system. Background Art

[0002] The raw material of carbon molecular sieve is phenolic resin powder. After adding glue, the phenolic resin powder is extruded in an extruder and then cut into particles. The particles are carbonized, adjusted and other processes to form a carbon molecular sieve. When producing phenolic resin powder, it is usually necessary to use a crusher to grind and crush the phenolic resin particles.

[0003] For example, a carbon molecular sieve raw material crushing system with the announcement number "CN215903824U" crushes phenolic resin three times through a coarse grinding mill, a fine grinding mill and a fine grinding mill to improve the crushing degree of phenolic resin; the coarsely ground phenolic resin is heated by a heating furnace to modify the phenolic resin so that the phenolic resin can be crushed more thoroughly during the fine grinding and fine grinding process; a fan is set at the front end of the fine grinding and coarse grinding mills so that the material can enter the corresponding grinder at a uniform speed to avoid the load fluctuation of the grinder. However, in the carbon molecular sieve raw material crushing system, after the phenolic resin particles pass through the coarse grinding mill, the qualified phenolic resin powder and the unqualified phenolic resin powder both enter the first silo, and the unqualified phenolic resin powder cannot be used for subsequent fine grinding, and the operator needs to spend a long time to distinguish them using tools, thereby reducing work efficiency. At the same time, in the carbon molecular sieve raw material crushing system, part of the phenolic resin powder will adhere to the inner wall of the first silo and cannot be discharged, requiring the operator to consume more physical strength to clean it, thereby increasing manual labor.

[0027] Working principle:

[0028] When crushing the carbon molecular sieve raw materials:

[0029] Preparation process:

[0030] The operator adds the carbon molecular sieve raw material that needs to be crushed (taking phenolic resin particles as an example) into the coarse grinding mill 16, and the operator inserts the dividing plate 17 along the slide groove processed on the box body 18, and then starts the power supply of the first motor 202. The output shaft of the first motor 202 rotates to drive the worm 203, thereby driving the worm gear 204 to rotate, and the rotation of the worm gear 204 drives the cam 205 to rotate, thereby driving the roller 206 to move, and the movement of the roller 206 drives the vertical rod 207 to move. When the cam 205 rotates 90 degrees clockwise, the vertical rod 207 moves upward to the maximum distance. At this time, the upper end of the vertical rod 207 is tightly pressed against the inner wall of the groove processed on the dividing plate 17. When the phenolic resin powder enters the box body 18, the dividing plate 17 can separate the phenolic resin powder with larger diameter and the relatively fine phenolic resin powder, and the operator does not need to spend a long time on screening. At the same time, a sealing gasket is provided at the connection between the dividing plate 17 and the box body 18 to prevent the phenolic resin powder from floating out.

[0031] Phenolic resin particle crushing process:

[0032] The operator starts the coarse grinding mill 16, which grinds the phenolic resin particles, and starts the induced draft fan 9, which generates negative pressure. The negative pressure is transmitted to the first pipe 12 through the bag filter 11, the second pipe 12 and the collecting hopper 13. The phenolic resin powder enters the collecting hopper 13 through the first pipe 12 under the action of the negative pressure. Most of the phenolic resin powder with a larger diameter enters the left side of the box 18 through the dividing plate 17 through the action of the first off-gas fan 15, and the remaining finer phenolic resin coarse powder enters the first bag filter 11 and gradually accumulates. Under the action of the second off-gas fan 10, it enters the right side of the box 18 through the dividing plate 17, opens the valve of the first discharge port 7 on the left, and discharges most of the phenolic resin powder with a larger diameter. Open the valve of the first discharge port 7 on the right, and discharge the remaining finer coarse phenolic resin powder. Start the power supply of the second motor 802, and the output shaft of the second motor 802 rotates to drive the incomplete gear 803 to rotate Thereby, the cross bar 804 is driven to move, and at the same time, the cylinder 805 is driven to slide along the slide groove processed on the second shell 801. When the incomplete gear 803 is not engaged with the cross bar 804, the second spring 806 rebounds and drives the cross bar 804 to move leftward, knocking the box body 18, so that the phenolic resin powder attached to the inner wall of the box body 18 falls off, and the operator does not need to consume much physical strength to clean it. The relatively fine coarse powder enters the heating furnace 3 from the first feed port 7 on the right side, and the heating furnace 3 is started. The heating furnace 3 heats the relatively fine coarse phenolic resin powder. The heated relatively fine coarse phenolic resin powder is discharged from the second discharge port 6 and enters the fine grinding mill 4. The fine grinding mill 4 is started to process the relatively fine coarse phenolic resin powder and finally discharged from the third discharge port 5. The processing process and discharge working mode of the heating furnace 3 and the fine grinding mill 4 are the same as the working mode of the heating furnace and the fine grinding mill in the authorization announcement number "CN215903824U".
