Description

Technical Field

[0001] This utility model relates to the technical field of raw material pulverizing devices, and more specifically, to a pulverizing device for methoxyphenamine hydrochloride raw material. Background Technology

[0002] Methoxyphenamine hydrochloride is a bronchodilator mainly used to relieve symptoms of respiratory diseases such as asthma and chronic bronchitis. The pulverization of its active pharmaceutical ingredient is a critical step in the pharmaceutical process, directly affecting the uniformity, solubility, bioavailability, and quality of subsequent formulation processes.

[0003] Existing raw material pulverizing equipment typically only has a pulverizing function. Raw materials need to be sieved before pulverizing and then transported, which wastes a lot of time and effort. At the same time, the pulverized raw materials need to be collected after pulverizing, which reduces the efficiency of raw material pulverizing.

[0004] A search revealed a Chinese patent with publication number CN218250638U that discloses a rapid pulverizing device for raw pharmaceutical materials. This utility model involves pouring the raw pharmaceutical material to be pulverized from the top of the feed trough. When the second motor is started, it drives the second rotating shaft to rotate. The second rotating shaft drives the rotating rod to rotate, causing the second filter screen to move back and forth in the feed trough, shaking and filtering the raw pharmaceutical material at the top of the second filter screen. After being screened, the raw pharmaceutical material moves from the first discharge port to the bottom, and then enters the feed port from the first discharge port for further pulverization, thus achieving the effect of pulverizing directly after screening.

[0005] However, when the above-mentioned pulverizing equipment is used to rapidly pulverize the raw material powder, the raw material powder will generate a certain amount of heat due to compression and friction. This heat will affect the raw material powder itself after it is concentrated and accumulated, thus affecting the drug properties of the raw material powder. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pulverizing device for methoxyphenamine hydrochloride raw material to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

The inner side of the shell is provided with... The device includes a dispersing mechanism; the dispersing mechanism includes a connecting frame, the outer side of which is fixedly connected to the inner side of the outer shell, three air inlet pipes fixedly connected to the outer side of the connecting frame, a filter plate one fixedly connected to one side of each air inlet pipe, a filter plate two fixedly connected to the inner side of the connecting frame, a fan fixedly connected to the inner side of each air inlet pipe, multiple shock absorbers fixedly connected to the inner side of the outer shell, a receiving plate fixedly connected to the top of each shock absorber, a vibrating motor fixedly connected to the bottom of the receiving plate, a centralized funnel fixedly connected to the inner side of the outer shell, and a secondary crushing mechanism provided on the inner side of the outer shell.

[0009] By adopting the above technical solution: using three fans to blow air into the inside of the shell to cool the crushed raw material powder, and at the same time using the vibration of the receiving plate to disperse the raw material powder, the raw material powder can move to the subsequent steps at a uniform speed.

[0010] As a further description of the above technical solution: the secondary crushing mechanism includes a second servo motor, the output end of which is fixedly connected to a rotating cone, multiple baffles are fixedly connected to the outer side of the rotating cone, a crushing ball is fixedly connected to the bottom of the rotating cone, a grinding seat is fixedly connected to the inner side of the outer shell, a guide plate is fixedly connected to the inner side of the grinding seat, a fan is fixedly connected to the outer side of the outer shell, a connecting pipe is fixedly connected to the output end of the fan, the outer side of the connecting pipe penetrates the inner side of the outer shell and extends into the interior of the grinding seat, a hopper is fixedly connected to the bottom of the outer shell, three baffles are fixedly connected to the top of the hopper, and multiple inclined air ducts are opened on the outer side of the baffles.

[0011] By adopting the above technical solution: the raw material powder is crushed in two stages using crushing balls and grinding blocks, and at the same time, multiple blowers and connecting pipes are used to blow air into the crushed raw material powder inside the grinding blocks, so that the raw material powder is concentrated through the feeding hopper under the obstruction and guidance of multiple baffles and inclined air ducts.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a dispersing mechanism, compared with the existing technology, the fan blows the crushed raw material powder, which reduces the heat generated by the crushing of the raw material powder. The vibration of the receiving plate keeps the raw material powder loose, avoiding local high temperature in the raw material powder that could lead to drug decomposition, and keeping the pulverized raw material powder with good drug properties.

[0014] 2. By setting up a secondary crushing mechanism, compared with the existing technology, the secondary crushing of raw material powder by crushing balls and grinding seats makes the raw material powder more uniformly crushed. At the same time, the feeding hopper and multiple baffles enable the raw material powder to be better collected and gathered, improving the crushing completion of the crushing device.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6 The methoxyphenamine hydrochloride raw material pulverizing equipment shown includes a shell 1, a feed hopper 2 fixedly connected to the top of the shell 1, a cover plate 3 hinged to the outside of the feed hopper 2, two ventilation filters 4 fixedly connected to the outside of the shell 1, a servo motor 5 fixedly connected to the outside of the shell 1, a crushing roller 6 fixedly connected to the output end of the servo motor 5, a gear 7 fixedly connected to a section of the crushing roller 6, a gear 8 meshing with one side of the gear 7, a crushing roller 9 fixedly connected to the inside of the gear 8, and the outside of the gear 8 and the crushing roller 9 rotatably connected to the inside of the shell 1. A dispersion mechanism is provided inside the shell 1; the dispersion mechanism includes a connecting frame 10, the outside of the connecting frame 10 fixedly connected to the inside of the shell 1, and the outside of the connecting frame 10 fixedly connected to... The system is equipped with three air inlet pipes 11. A filter plate 12 is fixedly connected to one side of the air inlet pipe 11, and a filter plate 29 is fixedly connected to the inside of the connecting frame 10. A fan 13 is fixedly connected to the inside of the air inlet pipe 11. Multiple shock absorbers 14 are fixedly connected to the inside of the outer shell 1. A receiving plate 15 is fixedly connected to the top of the shock absorber 14, and a vibrating motor 16 is fixedly connected to the bottom of the receiving plate 15. A centralized funnel 17 is fixedly connected to the inside of the outer shell 1. A secondary crushing mechanism is provided inside the outer shell 1 to blow and disperse the raw material powder after crushing by the crushing roller 16 and the crushing roller 29, and to dissipate heat. At the same time, the vibration motor 16 drives the receiving plate 15 to vibrate, so that the receiving plate 15 can uniformly convey the raw material powder to the centralized funnel 17 on one side.

[0024] Reference Figure 3 and Figure 5As shown, the secondary crushing mechanism includes a servo motor 18, with a rotating cone 19 fixedly connected to the output end of the servo motor 18. Multiple baffles 20 are fixedly connected to the outer side of the rotating cone 19. Crushing balls 21 are fixedly connected to the bottom of the rotating cone 19. A grinding seat 22 is fixedly connected to the inner side of the outer shell 1. A guide plate 23 is fixedly connected to the inner side of the grinding seat 22. A blower 24 is fixedly connected to the outer side of the outer shell 1. A connecting pipe 25 is fixedly connected to the output end of the blower 24. The connecting pipe 25 penetrates the inner side of the outer shell 1 and extends into the grinding seat 22. A hopper 26 is fixedly connected to the bottom of the outer shell 1. Three... Each baffle 27 has multiple inclined air ducts 28 on its outer side. A servo motor 218 drives a rotating cone 19, baffle 20, and crushing ball 21 to agitate and crush the raw material powder entering the central funnel 17 and grinding seat 22. At the same time, a guide plate 23 guides the air blown into the grinding seat 22 by the blower 24 and connecting pipe 25, so that the air can transport the raw material powder after secondary crushing to the top of the discharge hopper 26. The three baffles 27 and inclined air ducts 28 block and guide the raw material powder, causing it to fall downward into the inner side of the discharge hopper 26 for collection.

[0025] The working principle of this utility model is as follows: First, the raw material powder is fed into the interior of the outer shell 1 through the feed hopper 2. The servo motor 5 is started to drive the crushing roller 6 and gear 7 to rotate. Gear 7 meshes with gear 8, causing crushing roller 9 and crushing roller 6 to rotate in opposite directions. At the same time, the cover plate 3 is rotated to cover the top of the feed hopper 2. Then, three fans 13 are started to send outside air through the filter plate 12 to the interior of the connecting frame 10 through the air inlet pipe 11. The air is blown into the bottom of crushing roller 6 and crushing roller 9 through the connecting frame 10, so that the raw material powder crushed by crushing roller 6 and crushing roller 9 is dispersed by the air blown out by the connecting frame 10, and the heat generated by crushing is dissipated. Then, the crushed raw material powder falls to the top of the receiving plate 15. The vibration motor 16 drives the receiving plate 15 to vibrate up and down under the shock absorption support of the shock absorber 14. Under vibration conveying, the raw material powder moves to the concentration funnel 17 on one side, and then the raw material powder is gathered through the concentration funnel 17, causing the raw material powder to fall to the top of the grinding seat 22. Then, the servo motor 21 drives the rotating cone 19, baffle 20 and crushing ball 21 to rotate, so that the crushing ball 21 rotates and crushes the raw material powder inside the grinding seat 22. After secondary crushing, the raw material powder falls down along the grinding seat 22 into the interior of the grinding seat 22. At the same time, the blower 24 and connecting pipe 25 blow air into the interior of the grinding seat 22. When the air passes through the guide plate 23, it blows the raw material powder inside the grinding seat 22, causing the raw material powder to be blown from one side of the grinding seat 22 to the side of the hopper 26. Then, multiple baffles 27 and inclined air channels 28 block the raw material powder during the blowing process, allowing the raw material powder to fall into the interior of the hopper 26, completing the concentration of the raw material powder for subsequent collection.
