Description

Technical Field

[0001] This invention relates to a pulverizing device, and more particularly to a pulverizing device for solid drug particles. Background Technology

[0002] In the medical industry, it is often necessary to pulverize solid drug particles. Pulverized drug particles have a larger specific surface area, which allows the drug to dissolve in the gastrointestinal tract fluid more quickly, accelerating the release and absorption of the drug. For some poorly soluble drugs or drugs with low bioavailability, pulverizing them into smaller particles helps to improve their solubility and absorption rate in the body, thereby enhancing the efficacy of the drug.

It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Reference Figures 1-4A solid drug granule pulverizing device includes a base plate 1, a mounting box 2, a mounting frame 3, a cylinder 4, a spiral pressure bar 5, a rotating cylinder 6, a geared motor 7, a feed pipe 8, a discharge pipe 9, a scraper 10, a servo motor 11, and a receiving mechanism. The mounting box 2 is bolted to the top of the base plate 1. The mounting frame 3 is bolted to the middle of the top of the mounting box 2. The cylinder 4 is bolted to the upper part of the mounting frame 3. The spiral pressure bar 5 is connected inside the cylinder 4. The rotating cylinder 6 is rotatably connected to the top of the cylinder 4. The rotating cylinder 6 has a conical structure, wider at the bottom than the top. The geared motor 7 is bolted to the rear top of the cylinder 4. The output shaft of the geared motor 7 and the upper end of the rotating cylinder 6 are connected by a coupling. The device is connected to the upper left and right sides of the cylinder 4, and the feed pipes 8 are inclined so that the solid drug particles can fall into the cylinder 4 better. The discharge pipe 9 is rotatably connected to the bottom center of the cylinder 4, and the cylinder 4 and the discharge pipe 9 are connected. The upper end of the discharge pipe 9 is evenly spaced with scrapers 10. The scrapers 10 are in contact with the inner wall of the cylinder 4, and the scrapers 10 are arc-shaped so that they can better fit the inner wall of the cylinder 4, thereby better scraping off the drug powder remaining on the inner wall of the cylinder 4. The servo motor 11 is bolted to the rear top of the mounting box 2. The output shaft of the servo motor 11 and the discharge pipe 9 are driven by bevel gears. The receiving mechanism is used to collect the drug powder.

[0028] Reference Figure 3 and Figure 4 The receiving mechanism includes a receiving box 121, a water inlet pipe 122, and a discharge assembly. The receiving box 121 is connected to the top of the mounting box 2. The lower end of the discharge pipe 9 is rotatably connected to the top of the receiving box 121, and the discharge pipe 9 and the receiving box 121 are connected. The water inlet pipe 122 is connected to the front of the top of the receiving box 121. Water is poured into the receiving box 121 through the water inlet pipe 122. The drug powder and water are mixed to form a drug solution. The discharge assembly is used to discharge the drug solution.

[0029] Reference Figure 3 and Figure 4 The discharge assembly includes a water pump 123 and a drain pipe 124. The water pump 123 is installed in the middle of the bottom of the receiving box 121 by bolts. The suction end of the water pump 123 is connected to the receiving box 121. The drain pipe 124 is connected to the outlet end of the water pump 123 and extends from the right side of the mounting box 2.

[0030] The operator pours solid drug granules into the cylinder 4 through the feed pipe 8, then starts the reduction motor 7. The output shaft of the reduction motor 7 drives the rotating cylinder 6 to rotate. The rotating cylinder 6 has a conical structure that is smaller at the top and larger at the bottom, so the distance between the rotating cylinder 6 and the inner wall of the cylinder 4 gradually decreases from top to bottom. With the cooperation of the spiral pressure strip 5, the solid drug granules are squeezed and crushed. The drug powder falls downward and falls into the receiving box 121 through the discharge pipe 9. The servo motor 11 is then started. The output shaft drives the discharge pipe 9 to rotate via a bevel gear. The discharge pipe 9 drives the scraper 10 to rotate. The scraper 10 can scrape off the drug powder remaining on the inner wall of the cylinder 4, preventing the drug powder from sticking to the inner wall of the cylinder 4 and facilitating the discharge of the drug powder. After the solid drug particles are crushed, water is poured into the receiving box 121 through the water inlet pipe 122. The drug powder and water are mixed to form a drug solution. The water pump 123 can draw the drug solution into the drain pipe 124, and the drug solution is discharged through the drain pipe 124. The staff can collect the drug solution.

[0031] Reference Figure 5 The solid drug granule pulverizing device also includes a stirring mechanism, which includes a mounting ring 131 and a stirring frame 132. The lower part of the discharge pipe 9 is connected to the mounting ring 131, and three stirring frames 132 are evenly spaced around the outer circumference of the mounting ring 131.

[0032] When the discharge pipe 9 rotates, it will drive the mounting ring 131 to rotate, and the mounting ring 131 will drive the stirring frame 132 to rotate. The stirring frame 132 can stir the drug powder and water in the receiving box 121 to accelerate the dissolution of the drug powder.

[0033] Reference Figure 6 The solid drug granule pulverizing device also includes an anti-blocking mechanism, which includes a connecting rod 141 and a screw conveyor shaft 142. The connecting rod 141 is connected to the middle of the bottom of the rotating cylinder 6, and the screw conveyor shaft 142 is connected to the lower end of the connecting rod 141. The screw conveyor shaft 142 is located inside the discharge pipe 9, and the screw conveyor shaft 142 is in contact with the inner wall of the discharge pipe 9.

[0034] When the rotating drum 6 rotates, it can drive the connecting rod 141 to rotate, and the connecting rod 141 drives the screw conveyor shaft 142 to rotate. The screw conveyor shaft 142 can convey the drug powder in the discharge pipe 9 downward, so as to prevent the drug powder from being stuck in the discharge pipe 9.

[0035] Reference Figure 7 and Figure 8The solid drug granule pulverizing device also includes a striking mechanism, which includes a rotating shaft 151, a spur gear 152, a gear ring 153, a connecting block 154, a swing rod 155, a torsion spring 156, a striking shaft 157, and a contact block 158. The rotating shaft 151 is rotatably connected to the upper front side of the cylinder 4. The rotating cylinder 6 and the rotating shaft 151 are driven by a pulley system. The lower end of the rotating shaft 151 is connected to the spur gear 152 via a key. The gear ring 153 is rotatably connected to the middle of the cylinder 4. The gear ring 153 meshes with the spur gear 152. 53 Connecting blocks 154 are evenly spaced around the outer circumference. Each connecting block 154 is hinged with a swing rod 155. Two torsion springs 156 are connected between the swing rod 155 and the connecting block 154. Each swing rod 155 is connected to a striking shaft 157 at its lower part. The striking shaft 157 contacts the cylinder 4. Three contact blocks 158 are evenly spaced around the outer circumference of the cylinder 4. The side of each of the three contact blocks 158 that is far away from each other is an arc surface 159. The swing rod 155 will contact the arc surface 159 of the contact block 158 during rotation.

[0036] When the rotating cylinder 6 rotates, it can drive the rotating shaft 151 to rotate via the pulley assembly. The rotating shaft 151 drives the spur gear 152 to rotate, the spur gear 152 drives the gear ring 153 to rotate, and the gear ring 153 drives the connecting block 154 and the swing rod 155 to rotate, thereby driving the striking shaft 157 to rotate. During the rotation, the swing rod 155 will contact the arc surface 159 of the contact block 158 and swing along the arc surface 159 of the contact block 158, causing the striking shaft 157 to move away from the cylinder 4. The torsion spring 156 will deform. After the swing rod 155 and the contact block 158 are out of contact, under the action of the torsion spring 156, the striking shaft 157 moves towards the cylinder 4. The striking shaft 157 strikes the cylinder 4, causing the cylinder 4 to vibrate and shake off the drug powder adhering to the inner wall of the cylinder 4, thus preventing the drug powder from remaining on the inner wall of the cylinder 4.

[0037] Reference Figure 5 The solid drug granule pulverizing device also includes a heater 16. The heater 16 is bolted to the bottom of the receiving box 121. The heating tube of the heater 16 extends into the receiving box 121. The heater 16 can heat the drug powder and water in the receiving box to accelerate the dissolution process.
