Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical intermediate processing technology, specifically to a solid-liquid separation device for pharmaceutical intermediate processing. 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. When processing pharmaceutical intermediates, solid-liquid separation equipment is required for processing.

[0003] Currently, when performing solid-liquid separation on pharmaceutical intermediates, static sieves are generally used for filtration. Although this method can filter pharmaceutical intermediates, the filtration process is time-consuming and labor-intensive. Filtering pharmaceutical intermediates with a single static sieve can generally only filter larger pharmaceutical intermediates, while smaller pharmaceutical intermediates will not be filtered, which will affect the filtration effect and efficiency after filtration.

[0004] Therefore, a solid-liquid separation device for pharmaceutical intermediate processing is proposed to solve the problems mentioned above. Utility Model Content

This device solves the problem that, in the process of solid-liquid separation of pharmaceutical intermediates, static sieves are generally used for filtration. Although this method can filter pharmaceutical intermediates, the filtration process is time-consuming and labor-intensive. Filtering pharmaceutical intermediates with a single static sieve can generally only filter larger pharmaceutical intermediates, while smaller pharmaceutical intermediates will not be filtered, which affects the filtration effect and efficiency after filtration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a support frame, a motor fixedly connected to the outer side of the support frame, a hopper fixedly connected to the top of the support frame, a liquid storage tank located at the bottom inner side of the support frame, and a separation mechanism located on the inner side of the support frame.

[0009] Preferably, the spring is sleeved on the outside of the guide rod, one side of the slide plate is fixedly connected to one side of the connecting plate, a limit rod is inserted through the top of the connecting plate, and the limit rod is inserted through the connecting rod.

[0010] Preferably, a transmission mechanism is provided on the inner side of the support frame. The transmission mechanism includes rollers, a rotating shaft and an eccentric wheel. The rotating shaft is rotatably connected through the inner side of the support frame. An eccentric wheel is fixedly connected to the outer side of the rotating shaft. Rollers are fixedly connected to the top of the connecting plate.

[0011] Preferably, there are two rotating shafts, each with a synchronous pulley at one end. The two synchronous pulleys are connected by a synchronous belt. The outer side of the eccentric pulley is in contact with the outer side of the roller. One end of one rotating shaft is fixedly connected to one end of the motor's output shaft.

[0012] Preferably, a limiting mechanism is provided at the connection between the support frame and the liquid storage tank. The limiting mechanism includes a limiting plate, a limiting groove, a through groove, and a bracket. The limiting plate is integrally formed on the outer side of the liquid storage tank.

[0020] When in use, the well-mixed pharmaceutical intermediate is poured into the hopper 3 and filtered through the first filter screen 11 and the second filter plate 12. The mesh size of the first filter screen 11 is larger than that of the second filter plate 12, achieving a double-layer filtration effect. During the up-and-down vibration filtration, the inclined surfaces at the top of the first filter screen 11 and the second filter plate 12 allow solid materials to be discharged into the collection box 13 for collection, reducing the accumulation of solid materials.

[0021] Furthermore, the connecting rod 14 is slidably inserted into the inner side of the mounting groove 10, the inner wall of the mounting groove 10 is in contact with the outer wall of the connecting rod 14, and the end face of the connecting rod 14 has a T-shaped structure.

[0024] Furthermore, a transmission mechanism is provided on the inner side of the support frame 1. The transmission mechanism includes a roller 16, a rotating shaft 17, and an eccentric wheel 18. The rotating shaft 17 is rotatably connected through the inner side of the support frame 1. The eccentric wheel 18 is fixedly connected to the outer side of the rotating shaft 17.

[0025] The motor 2 drives the two rotating shafts 17 to rotate synchronously.

[0028] The working principle of the above embodiment is as follows: During use, the well-mixed pharmaceutical intermediate is poured into the hopper 3 and filtered through the first filter screen 11 and the second filter plate 12. The mesh size of the first filter screen 11 is larger than that of the second filter plate 12, achieving a double-layer filtration effect. During up-and-down vibration filtration, the inclined surfaces at the top of the first filter screen 11 and the second filter plate 12 allow solid materials to be discharged into the collection box 13 for collection, reducing the accumulation of solid materials. The motor 2 drives the two rotating shafts 17 to rotate synchronously. When the rotating shafts 17 drive the eccentric wheel 18 to rotate, the eccentric wheel 18 pushes down the roller 16, causing the connecting plate 9 to slide downwards. The spring 8 is compressed by the slide plate 7. When the eccentric wheel 18 rotates, the spring 8 is compressed and rebounds, so that the roller 16 and the eccentric wheel 18 are always in contact. The first filter screen 11 and the second filter plate 12 slide back and forth, which can play a certain anti-clogging effect and better complete the solid-liquid separation. The liquid storage tank 4 is connected to the support frame 1 through the limiting plate 19 and the limiting groove 20.
