Description

Technical Field

[0001] The present application relates to the technical field of solid medicine recovery and processing equipment, and in particular to a recovery and processing equipment for propylthiouracil. Background Art

[0002] Propylthiouracil is an organic compound that inhibits the synthesis of thyroid hormones by inhibiting the thyroid peroxidase system, preventing the iodination of tyrosine in the thyroid gland and the condensation of iodinated tyrosine. It is used for various types of hyperthyroidism. The drug is usually processed into granules and then packaged and sold. Since it is impossible to accurately control the specific demand of patients in the market and the specific demand of hospitals, it is impossible to accurately control the demand when producing drugs. However, in order to meet the demand, the supply of drugs will be greater than the demand. However, drugs have an expiration date. Once they expire or are about to expire, they will be immediately recycled and can no longer be sold. If the recycling is just to pile up the drugs together, it will waste a lot of space and resources, so the recycled drugs need to be crushed.

[0003] The current drug recovery device is composed of a crushing box, a crushing roller installed in the crushing box, a feed port and a discharge port, and a dust cover is provided on the upper end of the feed port. In the process of drug recovery and crushing, it is necessary to continuously discharge and add materials.

[0030] The upper end of the crushing treatment box 1 is provided with a pair of arc plates 11 located above the annular turntable 3 through a pair of support plates. It is worth noting that when the bracket 15 rotates with the annular turntable 3, the bracket 15 is located on the inner side of the arc plate 11 and will not contact the arc plate 11, that is, the arc plate 11 will not hinder the rotation of the bracket 15.

When the first touch sensor is sensed, the controller will control the hydraulic telescopic rod 16 to rise, and when the second touch sensor is sensed, the controller will control the hydraulic telescopic rod 16 to retract.

[0031] The specific working principle is: first, the recovered drugs to be processed are added into the storage barrel 804, and under the guidance of the feed hopper 801, the granular drugs will slide smoothly into the storage barrel 804. When the storage barrel 804 is full of drugs, the first servo motor and the second servo motor are started, and the second servo motor drives the lead screw 171 to rotate clockwise, and the rotation of the lead screw 171 drives the transmission block 172 to move downward. When the transmission block 172 moves downward, it pushes the lifting rod 901 downward through a pair of push-pull rods 174, and finally pushes the cover plate 903 to be inserted into the discharge pipe 14. When the lead screw 171 rotates, the gear 602 and the gear ring 603 mesh and drive the rotating cover 604 to rotate clockwise, and the rotating cover 604 rotates clockwise to drive the annular turntable 3 to rotate clockwise. When the clockwise rotation angle of the annular turntable 3 is 180 degrees, the second servo motor stops working. At this time, the through port 18 coincides with the feed port 5, and the cover plate 903 is completely inserted into the discharge pipe 14. When the through port 18 coincides with the feed port 5, the storage barrel 804 contacts the corresponding arc plate 11 and touches the first touch sensor. The first touch sensor An electrical signal is sent to the controller, and the telescopic end of the hydraulic telescopic rod 16 is controlled to rise upward, and the feed hopper 801 and the connecting piece 802 are driven to move upward through the support ring 805. When the connecting piece 802 moves upward, the feed opening and closing piece 808 is driven to move upward, so that the output end of the guide hopper 803 is opened, and the material slides into the crushing and processing box 1; after the feed hopper 801 moves upward, the bottom end of the conical guide cover 806 will contact the inner wall of the lower end of the feed hopper 801, and cover the feed hopper 801, so as to prevent dust from being blown out when feeding. Dust-free feeding can be achieved while the crushing roller 7 is running. When the medicine inside the crushing and processing box 1 is crushed, the second servo motor is driven again to make its output shaft rotate in the opposite direction, driving the lead screw 171 to rotate in the opposite direction, so that the transmission block 172 moves upward, and the lifting rod 901 is driven to move upward through a pair of push-pull rods 174, and finally the cover plate 903 is separated from the discharge pipe 14 for discharge.Under the drive of the rotating cover 604, the annular turntable 3 will rotate 180 degrees in the opposite direction, so that the through port 18 and the upper barrel assembly 8 return to the original state away from the feed port 5. At this time, the feed port 5 is covered by the annular turntable 3. When the storage barrel 804 contacts the other arc plate 11, the storage barrel 804 will touch the second touch sensor. The second touch sensor sends an electrical signal to the controller to control the telescopic end of the hydraulic telescopic rod 16 to retract, and drive the feed hopper 801 to move downward through the support ring 805, thereby driving the connecting piece 802 to move downward, and synchronously moving the feed opening and closing piece 808 downward to cover the output end of the guide hopper 803. At this time, the conical guide cover 8 The bottom end of 06 will also be away from the inner wall of the feed hopper 801, so as to continue to add the medicine to be crushed into the storage barrel 804, and add particulate matter into the storage barrel 804 while discharging the crushed medicine. When the crushed medicine in the crushing box 1 is discharged, repeat the above work again, so that the annular turntable 3 rotates 180 degrees clockwise, and the discharge opening and closing part 9 completes the covering action on the discharge pipe 14, and the feed opening and closing part 808 moves upward to leave the guide hopper 803, and the conical guide cover 806 contacts the inner wall of the feed hopper 801 to complete dust-free feeding. During the whole process, the first servo motor and the crushing roller 7 do not stop working, and dust-free operation is achieved throughout the whole process.
