Description

Technical Field

[0001] The invention relates to the technical field of pulverizers, and more specifically to an automatic diamond micro-powder pulverizer. Background Art

[0002] Diamond is a mineral composed of carbon and is a particle material composed of single elements in nature. In the diamond production process, a crushing device is used to crush diamond powder. The crushing of diamond powder is a complex process involving multiple steps and technologies. Among them, the airflow crushing method uses high-speed airflow to cause strong impact, collision and friction between particles, thereby achieving ultra-fine crushing of the material. The advantage is that airflow crushing can achieve very high crushing efficiency and is suitable for crushing high-hardness materials such as diamond powder.

[0003] In the process of air flow pulverization of diamond powder, it is very important to avoid the occurrence of dead corners. The so-called "dead corners" refer to places inside the pulverizer where it is difficult for materials to reach or air flow to circulate. These areas may cause material accumulation, affecting the pulverization effect and the normal operation of the equipment. When diamond powder is pulverized by air flow pulverizer, the reasons for the occurrence of dead corners of the equipment are nothing more than the following reasons:

[0004] 1. Diamond micropowder and other high-hardness materials tend to agglomerate during the crushing process. Agglomerated materials are difficult to be carried away by airflow, and dead corners are easily formed;

[0005] 2. Feeding too fast may cause materials to accumulate in certain areas, forming dead corners;

[0006] 3. Diamond powder contains moisture, which may cause the powder to agglomerate, thus affecting the crushing effect;

[0007] 4. The internal design of the equipment has complex structures or dead corners, which may cause material accumulation. Summary of the invention

[0008] In view of the problems existing in the prior art, the object of the present invention is to provide an automatic diamond powder pulverizer, which can solve the problem of dead corners when the air flow pulverizer pulverizes the diamond powder.

[0041] The rotating mechanism is arranged around the nozzle 8 to perform rotational disturbance on the airflow blown by the blower 6, so as to blow up the residual materials at the four corners inside the equipment and perform crushing operations to avoid excessive accumulation of materials inside the equipment and affect the normal operation of the equipment.

[0042] The rotating mechanism includes a motor 9 fixedly mounted on the upper end surface of the outer shell 1. The motor 9 is arranged on the right side of the input pipe 5. A rotating shaft 10 is fixedly mounted on the end of the output shaft at the upper end of the motor 9. A long shaft gear 11 is fixedly mounted on the outer surface of the rotating shaft 10. A toothed disc 12 is rotatably connected to the upper side of the outer surface of the nozzle 7, and the toothed disc 12 is meshed with the long shaft gear 11.

A transmission rod 15 is fixedly installed between the spherical shell 14 and the sleeve shell 16.

[0044] When the diamond powder is crushed by the equipment, the diamond powder enters the housing 1 through the input pipe 5, and then the blower 6 is started by the control main board 3 to blow out the airflow from the nozzle 8 to crush the diamond powder. When a dead angle appears, the motor 9 is started so that the output shaft of the motor 9 drives the rotating shaft 10 to rotate in the opposite direction, and the rotating shaft 10 will carry the long shaft gear 11 to rotate. The half gear 22 will not rotate under the action of the one-way bearing, and the long shaft gear 11 is meshed with the toothed disc 12, so the toothed disc will rotate, and the toothed disc carries the ball 13 to rotate, and the ball 13 is rotationally connected to the ball shell 14.

[0047] Then, the telescopic rod 21 drives the lifting plate 20 and the casing 16 to descend, so that the notch 18 on the casing 16 is connected with the nozzle 7 through the connecting port 17. At this time, the airflow in the nozzle 7 can be sprayed to the blind spot through the branch pipe 19. At the same time, the branch pipe 19 in the rotating state can increase the airflow spraying area, thereby avoiding the occurrence of blind spots. Moreover, as the telescopic rod 21 is adjusted up and down, the height can be adjusted according to the actual situation to further expand the airflow blowing area.

[0048] The drying mechanism is arranged on one side of the rotating mechanism and is connected to the rotating mechanism. When the diamond micropowder with high humidity is subjected to airflow crushing, it needs to be dried to ensure that its water content is lower than the specified value.

[0049] The drying mechanism includes a half gear 22 fixedly mounted on the upper end of the rotating shaft 10, a single-axis bearing is arranged inside the half gear 22, a support frame 23 is sleeved on the outer side of the half gear 22, and teeth 24 are fixedly mounted on the front end surface and the rear end surface inside the support frame 23, and the half gear 22 is meshed with the teeth 24.

The left end of the transmission column 26 extends to the outside of the sleeve 25 and is fixedly connected to the support frame 23.

[0051] A heating shell 30 is fixedly mounted on the front side of the upper end face of the housing 1 . A heating wire is arranged inside the heating shell 30 . An air inlet 31 is connected to the outer surface of the heating shell 30 . A heat pipe 29 is connected between the heating shell 30 and the sleeve 25 .

[0052] A one-way input valve is disposed inside the heat pipe 29 , and a one-way output valve is disposed inside the connecting pipe 28 .

[0053] When the diamond powder with high humidity is stirred by air flow, the electric heating wire inside the heating shell 30 is first started to heat the gas inside, and then the output shaft of the motor 9 drives the rotating shaft 10 to reverse, and under the action of the one-way bearing, the half gear 22 can be driven to rotate. When the teeth 24 on the half gear 22 rotate to mesh with the teeth 24 on the left side of the support frame 23, the support frame 23 will be driven to move forward. When the teeth 24 on the half gear 22 rotate to mesh with the teeth 24 on the right side of the support frame 23, the support frame 23 will be driven to move backward. The continuous rotation of the gear 22 will drive the support frame 23 to reciprocate, and the support frame 23 drives the piston plate 27 to reciprocate inside the sleeve 25 through the transmission column 26. When the piston plate 27 moves forward inside the sleeve 25, the one-way input valve in the heat pipe 29 will be opened, and the hot air inside the heating shell 30 will be drawn into the sleeve 25. When the piston plate 27 moves backward in the sleeve 25, the one-way output valve in the connecting pipe 28 will be opened, and the hot air in the sleeve 25 will be discharged into the nozzle 7, and then sprayed into the interior of the outer shell 1 with the nozzle 8 to dry the diamond powder.

[0054] The quantitative mechanism is arranged inside the input pipe 5 and is connected to the rotating mechanism in a transmission manner. The problem of dead corner accumulation inside the air flow mill can be solved by quantitatively inputting the material to ensure that the material enters the grinding chamber continuously and evenly.

[0055] The quantitative mechanism includes a blocking plate 33 fixedly installed inside the input pipe 5, and a plurality of through holes 1 34 are provided on the upper end surface of the blocking plate 33, and are dispersedly arranged in an annular shape. A rotating rod 35 is fixedly installed in the middle of the upper end surface of the blocking plate 33, and a gear plate 2 36 is rotatably connected to the outer surface of the rotating rod 35.

[0056] A rack 32 is fixedly mounted on the left end surface of the support frame 23 , and a second notch is provided on one side of the outer surface of the input pipe 5 , through which the rack 32 meshes with the second gear disc 36 .

[0057] At the same time, in order to avoid accumulation in dead corners inside the equipment, the equipment is also provided with a quantitative mechanism to carry out quantitative conveying processing of diamond micropowder. When the support frame 23 reciprocates, it will carry the rack 32 to reciprocate, and the rack 32 is engaged with the second gear plate 36, so the second gear plate 36 will reciprocate, so that the second through hole 37 on the second gear plate 36 and the first through hole 34 on the sealing plate 33 are overlapped in stages. By opening the input pipe 5, the diamond micropowder can be conveyed in stages.

[0058] Usage: When the diamond powder is crushed by the equipment, the diamond powder enters the housing 1 through the input pipe 5, and then the blower 6 is started by the control mainboard 3, so that the nozzle 8 blows out airflow to crush the diamond powder. When a dead angle appears, the motor 9 is started so that the output shaft of the motor 9 drives the rotating shaft 10 to rotate in the opposite direction, and the rotating shaft 10 will carry the long shaft gear 11 to rotate. The half gear 22 will not rotate under the action of the one-way bearing, and the long shaft gear 11 is meshed with the toothed disc 12, so the toothed disc will rotate, and the toothed disc carries the ball 13 to rotate, and the ball 13 is rotatably connected with the ball shell 14. The ball shell 14 drives the sleeve shell 16 to rotate through the transmission rod 15, and the branch pipe 19 at the lower end of the outer surface of the sleeve shell 16 will rotate synchronously;

[0059] Then, the telescopic rod 21 drives the lifting plate 20 and the casing 16 to descend, so that the notch 18 on the casing 16 is connected to the nozzle 7 through the connecting port 17. At this time, the airflow in the nozzle 7 can be sprayed to the blind spot through the branch pipe 19. At the same time, the branch pipe 19 in the rotating state can further increase the airflow spraying area, thereby avoiding the occurrence of blind spots. Moreover, as the telescopic rod 21 is adjusted up and down, the height can be adjusted according to the actual situation, thereby further expanding the airflow blowing area.

[0060] Secondly, when the diamond powder with high humidity is stirred by air flow, the electric heating wire inside the heating shell 30 is first started to heat the gas inside, and then the output shaft of the motor 9 drives the rotating shaft 10 to reverse, and under the action of the one-way bearing, the half gear 22 can be driven to rotate. When the teeth 24 on the half gear 22 rotate to mesh with the teeth 24 on the left side of the support frame 23, the support frame 23 will be driven to move forward. When the teeth 24 on the half gear 22 rotate to mesh with the teeth 24 on the right side of the support frame 23, the support frame 23 will be driven to move backward. The continuous rotation of the half gear 22 will drive the support frame 23 to reciprocate, and the support frame 23 drives the piston plate 27 to reciprocate inside the sleeve 25 through the transmission column 26. When the piston plate 27 moves forward inside the sleeve 25, the one-way input valve in the heat pipe 29 will be opened, and the hot air inside the heating shell 30 will be drawn into the sleeve 25. When the piston plate 27 moves backward inside the sleeve 25, the one-way output valve in the connecting pipe 28 will be opened, and the hot air in the sleeve 25 will be discharged into the nozzle 7, and then sprayed into the interior of the housing 1 along with the nozzle 8, so as to dry the diamond powder;

[0061] At the same time, in order to avoid accumulation in dead corners inside the equipment, the equipment is also provided with a quantitative mechanism to carry out quantitative conveying processing of diamond micropowder. When the support frame 23 reciprocates, it will carry the rack 32 to reciprocate, and the rack 32 is engaged with the second gear plate 36, so the second gear plate 36 will reciprocate, so that the second through hole 37 on the second gear plate 36 and the first through hole 34 on the sealing plate 33 are overlapped in stages. By opening the input pipe 5, the diamond micropowder can be conveyed in stages.
