Description

Technical Field

[0001] The invention belongs to the technical field of grinding devices, in particular to a material discharging device for producing and processing pharmaceutical intermediates. Background Art

[0002] The so-called pharmaceutical intermediates refer to some chemical raw materials or chemical products used in the process of drug synthesis, but they are secondary pharmaceutical raw materials that do not require a drug production license. In the production process of these pharmaceutical intermediates, they often appear in powder form. Therefore, a grinding device is needed to grind the raw materials from solid or granular form into powder form. Raymond mill is used for grinding pharmaceutical intermediates because of its reliable operation, low noise and uniform product particle size.

[0003] It generally consists of a sorting machine, a shell, a driving device and a grinding device. When working, the grinding roller rolls tightly on the grinding ring under the action of centrifugal force, and the scraper scoops up the material and sends it to the middle of the grinding roller and the grinding ring. The material is crushed into powder under the action of the grinding pressure, and then the powdered material is blown up by the action of the fan and passes through the sorting machine. The material that meets the fineness requirements passes through the analyzer, and the material that does not meet the requirements returns to the grinding chamber for further grinding, thereby achieving the effect of one-time powdering. However, after a long period of grinding, when the grinding roller and the grinding ring need to be maintained and replaced, due to the connection of the driving device, when replacing the annularly distributed grinding roller, it is necessary to overcome the damping and jamming caused by the motor, which makes the maintenance process difficult.

[0034] The second motor 41 drives the second rotating wheel 42 to rotate, and the second belt 43 transmits the rotational force to the third rotating wheel 44, so that the rotating shaft 45 rotates, thereby driving the first blade 46 and the second blade 410 to rotate, providing an auxiliary force for blowing upwards, and powders of appropriate sizes are discharged from the discharge port 32 through the first blade 46 and the second blade 410, and particles with larger particle sizes fall back into the shell 31, and after being reprocessed by the grinding device 5, they are blown upward again for sorting. By increasing or shortening the stroke of the second hydraulic rod 48, the first blade 46 is pushed to rotate a certain angle through the connecting rod 47, thereby changing the size of the gap formed between the first blade 46 and the second blade 410, so as to adjust the discharge size of the powder;

[0035] The grinding device 5 comprises a plum blossom frame 51, which is provided with a plurality of circular holes 510. Four third hydraulic rods 52 are fixedly installed on the top of the plum blossom frame 51. The telescopic ends of the four third hydraulic rods 52 are fixedly connected with fixed blocks 53. A round shaft 54 ​​is fixedly plugged on the top of the fixed block 53. The round shaft 54 ​​is rotatably installed on the top of the table 12. The side annular array of the plum blossom frame 51 has three groups of connecting rods 55. The bottoms of the three groups of connecting rods 55 are all rotatably installed with grinding rollers 56. A plurality of scrapers 57 are fixedly connected to the lower middle part of the round shaft 54. The scrapers 57 are fan-shaped and can generate wind force from bottom to top when rotating.

[0036] The plug-in rod 65 rotates, and then the connecting ring 58 drives the circular shaft 54 ​​connected thereto to rotate, so that the multiple grinding rollers 56 can rotate closely against the grinding ring 59, and the multiple scrapers 57 can also generate wind force from bottom to top when rotating. The raw materials will fall to the bottom of the shell 31 under the factor of gravity, and part of the raw materials will pass through the gap between the plum blossom frame 51 and the shell 31 and be directly ground by the grinding rollers 56 and the grinding ring 59, and part of the raw materials will pass through the circular hole 510 and be scooped up by the scraper 57 and close to the grinding roller 56 under the action of wind force and centrifugal force, so as to complete the grinding;

[0037] The air inlet device 7 includes an air guide duct 71, which is fixedly connected to the bottom end of the housing 31, the bottom surface of the air guide duct 71 is fixedly connected to the table 12, an air guide seat 72 is fixedly installed inside the air guide duct 71, a U-shaped tube 73 is fixedly connected to the front side of the air guide duct 71, a filter screen 74 is installed on the front side and top side of the U-shaped tube 73, a support rod 75 is fixedly installed on the rear side of the U-shaped tube 73, and the tail end of the support rod 75 is fixedly connected to the table 12;

[0038] The air can be continuously drawn into the shell 31 through the air inlet device 7 , and the air enters the U-shaped tube 73 through the filter 74 , and enters the air guide duct 71 for collection, and then evenly enters the shell 31 from the air guide seat 72 .

[0039] Working principle:

[0040] When the raw materials of pharmaceutical intermediates are ground, the grinding device 5 is first started in advance by the driving device 2, the first motor 22 rotates, driving the first rotating wheel 23 to rotate, and the power is transmitted to the fourth rotating wheel 66 through the first belt 24, thereby driving the plug-in rod 65 to rotate, and then driving the circular shaft 54 ​​plugged therein to rotate through the connecting ring 58, so that the multiple grinding rollers 56 can rotate closely against the grinding ring 59, and the multiple scrapers 57 can also generate wind force from bottom to top when rotating.

[0041] At this time, the raw materials are put into the shell 31 through the feed port 34. The raw materials fall to the bottom of the shell 31 due to gravity. Some of the raw materials pass through the gap between the plum blossom frame 51 and the shell 31 and are directly ground by the grinding roller 56 and the grinding ring 59. Some of the raw materials pass through the circular hole 510 and are scooped up by the scraper 57 and are close to the grinding roller 56 under the action of wind and centrifugal force, thereby completing the grinding.

[0042] Under the rotational force of the scraper 57, air is continuously drawn into the housing 31 through the air inlet device 7, and the air passes through the filter 74 into the U-shaped tube 73, and then enters the air guide 71 for collection, and then evenly enters the housing 31 from the air guide seat 72;

[0043] After the raw material is processed into powder, it becomes lighter due to its own gravity, and it will continue to move upward under the blowing of the scraper 57 to reach the sorting device 4. At this time, the second motor 41 drives the second rotating wheel 42 to rotate, and transmits the rotational force to the third rotating wheel 44 through the second belt 43, thereby rotating the shaft 45, thereby driving the first blade 46 and the second blade 410 to rotate, providing an auxiliary force for blowing upward, and the powder of suitable size will be discharged from the discharge port 32 through the first blade 46 and the second blade 410, and the particles with larger particle size will fall back into the shell 31, and after being reprocessed by the grinding device 5, they will be blown upward again for sorting. By increasing or shortening the stroke of the second hydraulic rod 48, the first blade 46 is pushed to rotate a certain angle through the connecting rod 47, thereby changing the size of the gap formed between it and the second blade 410, thereby adjusting the discharge size of the powder;

[0044] When it is necessary to overhaul and replace wearing parts of the equipment, the fourth hydraulic rod 61 and the first hydraulic rod 21 are increased by the same stroke at the same time. At this time, the first motor 22, the first rotating wheel 23 and the first belt 24 will all move downward a certain distance, and the forked rod 63, under the push of the fourth hydraulic rod 61, cancels the connection between the plug-in rod 65 and the connecting ring 58. At this time, the three sets of grinding rollers 56 will cancel the damping and jamming caused by the connection with the first motor 22. Opening the inspection door 33 can facilitate the maintenance and replacement of the grinding rollers 56 and the grinding rings 59, and the workflow ends here.
