Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical intermediate production equipment, specifically to an energy-saving vacuum feeder for pharmaceutical intermediate production. Background Technology

[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis.

[0003] For example, an existing Chinese authorized patent (publication number: CN212923538U) discloses an energy-saving vacuum feeder for pharmaceutical intermediate production, including a base, a feed inlet, a transmission box, a hopper, and a crushing box. The crushing box is fixedly installed on one side of the base, and the transmission box is located at the top of the crushing box. A motor is fixedly installed on the top of the transmission box, and the output shaft of the motor extends through the top of the transmission box and is fixedly connected to a drive gear inside it. Driven gears are meshed on both sides of the drive gear. A rotating shaft is fixedly connected to the axis of both the drive gear and the driven gear. Several cutters are installed on the outer surface of the rotating shaft. The cutters on the three rotating shafts are arranged alternately. By providing three filter screens in the hopper and installing a vibrator below each filter screen, the crushed particles enter the filter screens in the hopper and are filtered layer by layer by the filter screens to obtain finer powder raw materials, which is convenient for pharmaceutical intermediate production and processing and improves production and processing efficiency.

[0004] The energy-saving vacuum feeder for pharmaceutical intermediate production designed above has the following disadvantages in actual use: In the above case, the raw material is turned into powder and enters the hopper through the vacuum pump and the discharge pipe. However, the feed pipe is located above the right side of the crushing box. When extracting, the vacuum pump inlet hose lacks an effective driving adjustment structure and cannot be flexibly adjusted, which makes it impossible to effectively suck up the raw material at the bottom of the storage box, resulting in raw material residue and waste.

[0005] In view of this, an energy-saving vacuum feeder for the production of pharmaceutical intermediates is provided to overcome the above-mentioned defects. Utility Model Content

[0020] Example 1 like Figure 1-4 As shown, an energy-saving vacuum feeder for pharmaceutical intermediate production according to an embodiment of the present invention includes a receiving container 1, a base plate 2 on the right side of the receiving container 1, vertical rods 3 symmetrically arranged on the top of the base plate 2, a drive mechanism 4 on the opposite side of the vertical rods 3, a movable top plate 5 between the drive mechanisms 4, a braking mechanism 6 at the bottom of the movable top plate 5, a conical cylinder 8 connected to the top of the receiving container 1 by multiple support rods 7, a vacuum pump 9 on the top of the conical cylinder 8, a hose 10 connected to the right side of the vacuum pump 9, the hose 10 being located on one side of the braking mechanism 6, and a storage container 11 located below the hose 10, with the storage container 11 located on the top of the base plate 2.

[0021] In this embodiment, the drive mechanism 4 is the core power source, providing linear motion in the vertical direction. The movable top plate 5 is the output end of the drive mechanism 4 and serves as a bearing platform. It is directly driven by the drive mechanism 4 to move up and down. The braking mechanism 6 is installed at the bottom of the movable top plate 5 and is used to install the hose 10. After the movable top plate 5 is driven, it directly moves the hose 10 downward. First, the drive mechanism 4 is started by an external switch. The drive mechanism 4 moves the moving top plate 5 downward. The braking mechanism 6 is fixed to the bottom of the moving top plate 5, so it also moves downward with the moving top plate 5. The upper end of the hose 10 is fixed to the braking mechanism 6. Therefore, the entire body of the hose 10, especially its lower suction port, also moves downward. During the downward movement of the hose 10, its suction port will contact the raw material above the inner cavity of the storage container 11. The negative pressure source (vacuum pump 9) works and generates suction through the hose 10 to start sucking up the raw material. As the suction process continues, the amount of raw material in the storage container 11 gradually decreases, and the material level drops accordingly. In order to ensure that the suction port of the hose 10 can always effectively contact or be immersed in the raw material (avoiding suction of air or air intake), the drive mechanism 4 needs to continue to move downward slowly to ensure that the suction port of the hose 10 always follows the material level as it descends. Example 2 The drive mechanism 4 includes a drive groove 12, a lead screw 13, a drive block 14, and a servo motor 15. The drive groove 12 is located on one side of the vertical rod 3. The lead screw 13 is located at the bottom of the inner cavity of the drive groove 12. The drive block 14 is connected to the outer wall of the lead screw 13 via a reverse thread. The servo motor 15 is connected to the top of the lead screw 13. The servo motor 15 is located at the top of the vertical rod 3 and is electrically connected to an external switch. The movable top plate 5 is located between the drive blocks 14, and the connection between the drive blocks 14 and the movable top plate 5 is fixed. The vertical rod 3 serves as the core support and guide, the main support of the equipment, and provides vertical guidance and a foundation for component installation. The drive groove 12 has a longitudinal groove along the side of the vertical rod 3 to accommodate the lead screw 13 and the drive block 14, restricting the drive block 14 to only move vertically along the groove (anti-rotation). Servo motor 15 serves as the power source, vertically fixed to the top of the vertical rod 3. Its output shaft directly drives the top of the lead screw 13 (rigidly connected via a coupling). The power cord is electrically connected to an external switch (receiving start / stop / speed control signals). The lead screw 13 motion conversion mechanism is vertically installed at the bottom of the inner cavity of the drive groove 12 (fixed by a bearing at the bottom and connected to the motor at the top). It features a reverse thread (left-hand thread) design, ensuring that the drive block 14 moves downward when rotating clockwise. It is restricted by the drive groove 12 and can only perform rotational motion (cannot move axially). The drive block 14 is a threaded motion actuator, nested within the drive groove 12, and threadedly engaged with the lead screw 13. A reverse thread is located in the center. The groove is threaded and engages with the external thread of the lead screw 13. Its outer contour matches the drive groove 12. It is restricted by the groove wall and can only slide up and down (cannot rotate). The moving top plate 5 is a motion output platform. It is horizontally connected between the two drive blocks 14 (usually symmetrical double lead screw drive). It is rigidly fixed to the drive blocks 14 (no relative movement) to ensure 100% power transmission. The servo motor 15 is started by an external switch. The servo motor 15 drives the lead screw 13 to rotate. The drive block 14 is forced to move downward along the axis of the lead screw 13 due to the thread engagement. The drive block 14 rigidly pulls the moving top plate 5 to move down synchronously. The moving top plate 5 moves down and drives all the components at its bottom to move down synchronously. The braking mechanism 6 includes a brake rod 16, a first mounting rod 17, and a second mounting rod 18. The brake rod 16 is symmetrically arranged at the bottom of the movable top plate 5. The first mounting rod 17 is located at the bottom of the brake rod 16, and the second mounting rod 18 is located to the right of the first mounting rod 17. The hose 10 is located at the bottom of the first mounting rod 17 via a mounting ring 19 and extends to the left of the second mounting rod 18. All components of the braking mechanism 6 are fixed to the bottom of the movable top plate 5 and move synchronously with the top plate. The brake rod 16 is symmetrically and vertically installed on both sides of the bottom of the movable top plate 5, serving only as structural support (not interfering with movement). The first mounting rod 17 is rigidly fixed to the bottom of the brake rod 16, and the first mounting rod 17 and the second mounting rod 18 are also rigidly connected, providing the main support point for the mounting ring 19. The movable top plate 5 moves downward with the brake rod 16, the first mounting rod 17, the second mounting rod 18, and the hose 10 connected to them via the mounting ring 19. The suction port at the lower end of the hose 10 contacts the raw material in the storage container 11. In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the servo motor 15 is first started by an external switch. The servo motor 15 drives the lead screw 13 to rotate. The drive block 14 is forced to move downward along the axial direction of the lead screw 13 due to the thread engagement. The drive block 14 rigidly pulls the moving top plate 5 to move downward synchronously. The moving top plate 5 moves downward and drives all its bottom components to move downward synchronously. That is, the moving top plate 5 moves downward along with the brake rod 16, the first mounting rod 17, the second mounting rod 18 and the hose 10 connected to it by the mounting ring 19. The suction port of the lower end of the hose 10 contacts the raw material in the storage container 11. The negative pressure system (vacuum pump 9) is started and generates suction through the hose 10. The raw material is sucked into the conveying pipe. As the suction process continues, the amount of raw material in the storage container 11 gradually decreases and the material level drops accordingly. In order to ensure that the suction port of the hose 10 can always effectively contact or be immersed in the raw material (avoiding suction of air or air intake), the drive mechanism 4 needs to continue to move downward slowly to ensure that the suction port of the hose 10 always follows the material level as it drops.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
