[0040] Please refer to Figures 1 to 4 The utility model provides a camphor powder crushing device, including the rubbing crusher 1, feed hopper 2, discharge pipe 3, vibrating screen 4, back material pipe 5 and feed pump 6.

[0041] Specifically, the feed hopper 2 is installed at the inlet 4211 of the top of the rubbing crusher 1, which is communicated with the inside of the rubbing crusher 1, and the feed hopper 2 is connected with the raw material storage tank storing large particle camphor powder through pipeline, the rubbing crusher 1 is provided with two rubbing rollers 9 capable of moving towards each other, so that the large particle camphor powder can enter the rubbing crusher 1 through the feed hopper 2, and then be crushed into fine particle camphor powder by the rubbing crusher 1. The discharge pipe 3 is installed at the discharge port of the rubbing crusher 1. The vibrating screen 4 is provided with an inlet 4211 communicated with the discharge pipe 3, so that the camphor powder pre-crushed by the rubbing crusher 1 can enter the vibrating screen 4 for screening treatment.

[0042] The vibrating screen 4 is provided with a coarse powder discharge port 4212 and a fine powder discharge port 4221, and the back material pipe 5 is communicated with the coarse powder discharge port 4212 and the feed hopper 2 respectively, and the input end and the output end of the feed pump 6 are both communicated with the back material pipe 5, so that the coarse particle camphor powder not screened out by the vibrating screen 4 can be discharged from the coarse powder discharge port 4212 and then conveyed back to the feed hopper 2 through the back material pipe 5 under the action of the feed pump 6, so that the large particle camphor powder can be conveyed back to the rubbing crusher 1 through the back material pipe 5 again and be crushed by the rubbing crusher 1.

[0043] Compared with the way of screening camphor powder by installing screen 432 inside the pulverizer 1, the utility model does not need to install screen 432 inside the pulverizer 1, but sets vibration screen 4 outside the pulverizer 1, so that the camphor powder pre-pulverized by the pulverizer 1 can enter vibration screen 4 for screening treatment. Since the impact force of the screen 432 structure for screening in the vibration screen 4 is smaller than that inside the pulverizer 1, the screen 432 will not be subjected to greater wear, thereby reducing the cost of equipment maintenance.

[0044] It can be understood that the fine particle camphor powder screened by the vibration screen 4 can be conveyed to the fine material tank 8 through the pipeline for grinding by the superfine grinder.

[0045] Optionally, the bottom of the pulverizer 1 is conical, and the conical bottom can promote the flow of camphor powder, so that the camphor powder is more smoothly discharged from the bottom of the pulverizer 1.

[0046] Optionally, the vibration screen 4 comprises a support assembly 41, a vibration screen box 42, a screen 432 assembly 43 and a vibration motor 44. Specifically, the support assembly 41 is arranged below the discharge pipe 3. The bottom of the vibration screen box 42 is inclined downward and arranged on the support assembly 41. The screen 432 assembly 43 is parallel to the bottom of the vibration screen box 42, that is, the screen 432 assembly 43 is also in an inclined downward state. The vibration motor 44 is arranged on the top side of the vibration screen box 42, and can generate high-frequency vibration when working, so as to make the vibration screen 4 vibrate.

[0047] The screen 432 assembly 43 divides the vibration screen box 42 into a distribution bin 421 with a feeding port 4211 and a coarse powder discharge port 4212, and into a discharge bin 422 with a fine powder discharge port 4221. When the camphor powder pre-pulverized by the pulverizer 1 enters the vibration screen 4, the camphor powder first falls into the distribution bin 421, and then under the vibration of the vibration screen 4, the fine particle camphor powder passes through the screen 432 assembly 43 and falls onto the inner bottom of the discharge bin 422 (i.e. the bottom of the vibration screen box 42). By arranging the screen 432 assembly 43 and the bottom of the vibration screen box 42 inclined downward, the powder can flow downward, so that the coarse particle camphor powder and the fine particle camphor powder can be smoothly discharged from the coarse powder discharge port 4212 and the fine powder discharge port 4221 of the vibration screen 4 respectively. Therefore, it can be understood that the coarse powder discharge port 4212 should be arranged on the lower side of the screen 432 assembly 43, and the fine powder discharge port 4221 should be arranged on the lower bottom surface of the vibration screen box 42.

[0048] Optionally, the lower end of the distribution bin 421 and the screen 432 assembly 43 extends to the front side of the lower end of the discharge bin 422, and the vibrating screen 4 further comprises a first pipe joint 45. The first pipe joint 45 is arranged on the lower bottom surface of the screen 432 assembly 43, and the first pipe joint 45 is in communication with the coarse powder discharge port 4212, and the return pipe 5 is in communication with the distribution bin 421 through the first pipe joint 45.

[0049] By extending the lower end of the distribution bin 421 and the screen 432 assembly 43 to the front side of the lower end of the discharge bin 422, the coarse powder discharge port 4212 and the fine powder discharge port 4221 can be arranged staggered, so that the powder in the distribution bin 421 and the discharge bin 422 can be smoothly discharged from the inside of the two bin bodies.

[0050] Optionally, the vibrating screen 4 further comprises a second pipe joint 46 and a flexible sleeve 47. The second pipe joint 46 can be arranged on the top of the vibrating screen box 42, and the second pipe joint 46 is in communication with the inlet port 4211. The upper end and the lower end of the flexible sleeve 47 are fixedly sleeved on the discharge pipe 3 and the second pipe joint 46 respectively. The material of the flexible sleeve 47 can be consistent with the material of the cloth bag of the bag-type dust collector, which can not only connect the discharge pipe 3 and the second pipe joint 46, but also ensure the independent vibration of the vibrating screen 4.

[0051] Optionally, the screen 432 assembly 43 comprises a screen frame 431, and a screen 432 and a guide plate 433 arranged in the screen frame 431. The screen 432 and the guide plate 433 are both arranged inclined downward, and the screen 432 is detachably arranged in the screen frame 431, so as to facilitate replacement and meet the needs of screening camphor powder of different fineness. The guide plate 433 is detachably connected with the lower end of the screen 432, and the coarse powder discharge port 4212 is arranged on the guide plate 433, so that the coarse-grained camphor powder can be discharged from the distribution bin 421 (vibrating screen 4) through the coarse powder discharge port 4212.

[0052] Optionally, the support assembly 41 comprises a first rack 411, a damping spring 412 arranged on the first rack 411, and a second rack 413 located on the upper end of the damping spring 412 and connected with the damping spring 412. The second rack 413 is connected with the bottom of the vibrating screen box 42, so as to ensure that the bottom of the vibrating screen box 42 can be arranged inclined. The damping spring 412 can provide necessary support for the vibrating screen box 42, ensure stable operation of the vibrating screen 4, ensure effective screening of the filter screen assembly, and effectively absorb the impact force generated by vibration, thereby reducing the noise during operation of the machine.

[0053] Optionally, the top of the vibrating screen box 42 is provided with a mounting seat 48, and the vibrating motor 44 is arranged on the mounting seat 48 in an upwardly inclined manner.
