Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a vacuum freeze dryer for preparing drugs. Background Technology

[0002] Vacuum freeze dryers, also known as freeze dryers, involve first freezing materials below their eutectic point temperature, turning the water in the material into solid ice, and then, under a suitable vacuum, causing the ice to sublimate directly into water vapor. The water vapor is then condensed using a water trap in the vacuum system, thus obtaining the dried product. It mainly consists of a freeze-drying chamber, a cold trap (cold trap box), a heating system, a vacuum system, a refrigeration system, and a control system.

[0003] According to Chinese Patent Publication No. CN215295567U, a vacuum freeze dryer for preparing drugs is disclosed. It uses a drug placement tray structure to connect bearing rollers in a limiting groove, which can improve the stability of the connection between the drug placement tray and the main body of the drying chamber and facilitate the installation process of the main body of the drying chamber to pull out or push in the drug placement tray. The limiting groove structure can limit the drug placement tray connected to the side end, thereby improving the stability of the connection between the main body of the drying chamber and the drug placement tray.

[0004] However, in this technical solution, when a large number of drugs are placed in the drug storage box, the drugs tend to accumulate in the drug storage box, making it difficult for the accumulated drugs to come into good contact with the air inside the drying chamber. As a result, it is difficult to effectively dry the accumulated drugs, thus affecting the drying effect of the drugs. Therefore, we propose a vacuum freeze dryer for preparing drugs. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum freeze dryer for preparing drugs, which solves the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum freeze dryer for preparing drugs, comprising a drying chamber body, a drying component and a placement box, wherein the drying component is fixedly installed on the inner side of a plate frame, the plate frame is fixedly installed on both sides of the inner wall of the drying chamber body, the placement box is slidably connected to the plate frame, and a flipping mechanism is provided on the placement box;

[0007] The flipping mechanism includes a motor, a rotating frame, and a carrier plate. The carrier plate is slidably connected to the inner wall of the placement box. A spring is fixedly connected between the bottom end of the carrier plate and the inner wall of the placement box. A protrusion is fixedly installed near the edge of the top of the carrier plate. A support frame is fixedly installed at the top of the placement box. The motor is fixedly installed at the top of the support frame. The rotating frame is driven by the motor. Protrusions are fixedly installed at both ends of the rotating frame. A stirring plate is fixedly installed at the top of the inner wall of the rotating frame. A contact switch is fixedly installed on the back of the placement box. The contact switch is electrically connected to the motor.

[0008] Preferably, a rotating shaft is fixedly installed at the output end of the motor. The rotating shaft passes through the top of the support frame and is rotatably connected to the support frame through a bearing. The rotating frame is fixedly installed at the bottom end of the rotating shaft. By setting the rotating shaft, the motor can drive the rotating frame to rotate through the rotating shaft.

[0009] Preferably, a limiting rod is fixedly installed at the bottom end of the carrier plate, and a rod hole is opened at the bottom end of the inner wall of the placement box. The limiting rod moves through the rod hole, and the spring surrounds the outer wall of the limiting rod. By setting the limiting rod, the spring can be limited, ensuring the stability of the spring when compressed.

[0010] Preferably, a support pad is fixedly installed on the top of the carrier plate. The support pad is made of sponge. By setting the support pad, a certain buffering and protection effect can be provided for the medicine when it is stirred and turned, so as to avoid hard collision between the medicine and the carrier plate, which would cause the medicine to break and affect the normal use of the medicine.

[0011] Preferably, a support slide plate is fixedly installed on both sides of the placement box, and a support slide groove is opened on the inner side of the plate frame. The support slide plate and the support slide groove are slidably connected. By setting the support slide plate and the support slide groove, the placement box can play a certain supporting and limiting role.

[0012] Preferably, the drying oven body has a door hinged to the front, and a support block is fixedly installed at the bottom of the drying oven body.

[0013] This invention provides a vacuum freeze dryer for preparing pharmaceuticals. This vacuum freeze dryer for preparing pharmaceuticals has the following beneficial effects:

[0014] (1) The vacuum freeze dryer for preparing drugs can stir and turn the drugs on the carrier plate by setting a turning mechanism, thereby increasing the contact between the drugs and the cold air inside the drying chamber, avoiding the accumulation of drugs in the placement box, which makes it difficult for some drugs to be dried effectively. This solves the problem in the prior art that when a lot of drugs are placed in the drug placement box, the drugs are easy to accumulate in the drug placement box, making it difficult for the drugs accumulated inside to contact the air inside the drying chamber, thus making it difficult to effectively dry the drugs accumulated inside, and thus affecting the drying effect of the drugs.

[0015] (2) The vacuum freeze dryer for preparing the drug can provide a certain buffer protection for the drug when it is stirred and turned by setting a support pad, so as to avoid hard collision between the drug and the carrier plate, which would cause the drug to break and affect the normal use of the drug.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: a vacuum freeze dryer for preparing drugs, including a drying chamber body 1, a drying component 10 and a placement box 3. The drying component 10 is fixedly installed inside the plate frame 2. The plate frame 2 is fixedly installed on both sides of the inner wall of the drying chamber body 1. The placement box 3 is slidably connected to the plate frame 2. A flipping mechanism 4 is provided on the placement box 3.

[0026] The flipping mechanism 4 includes a motor 402, a rotating frame 404, and a carrier plate 406. The carrier plate 406 is slidably connected to the inner wall of the placement box 3. A spring 409 is fixedly connected between the bottom end of the carrier plate 406 and the inner wall of the placement box 3. A protrusion 410 is fixedly installed at the top edge of the carrier plate 406. A support frame 401 is fixedly installed at the top of the placement box 3. The motor 402 is fixedly installed at the top of the support frame 401. The rotating frame 404 is connected to the motor 402 in a transmission connection. Protrusions 411 are fixedly installed at both ends of the rotating frame 404. A stirring plate 405 is fixedly installed at the top of the inner wall of the rotating frame 404. A contact switch 412 is fixedly installed on the back of the placement box 3. The contact switch 412 is electrically connected to the motor 402.

[0027] Specifically, in the above technical solution, when using the vacuum freeze dryer for preparing the drug, the drug to be dried is placed on the carrier plate 406 in the placement box 3, and then the placement box 3 is pushed into the drying chamber body 1. Finally, the placement box 3 drives the contact switch 412 to contact the inner wall of the drying chamber body 1. At this time, the motor 402 is turned on, and the motor 402 drives the rotating shaft 403 to rotate. The rotating shaft 403 drives the rotating frame 404 to rotate. The rotating frame 404 drives the stirring plate 405 to stir the drug on the carrier plate 406. When the rotating frame 404 rotates, it drives the second protrusion 411 to make a circular motion. When the second protrusion 411 contacts the first protrusion 410, the second protrusion 411 will squeeze the first protrusion 410, causing the first protrusion 410 to drive the carrier plate 406 to move downward, so that the carrier plate 406 squeezes the spring 409. When the second protrusion 411 does not contact the first protrusion 410, the second protrusion 411 will squeeze the first protrusion 410, causing the first protrusion 410 to drive the carrier plate 406 to move downward, so that the carrier plate 406 squeezes the spring 409. When block 410 contacts, the carrier plate 406 will move upward under the reset force of spring 409, so that the carrier plate 406 can vibrate intermittently when the rotating frame 404 rotates, thereby causing the medicine on the carrier plate 406 to turn over. Through the above structure, the medicine on the carrier plate 406 can be stirred and turned over, thereby increasing the contact between the medicine and the cold air inside the drying oven body 1, avoiding the accumulation of medicine in the placement box 3, which makes it difficult for some medicines to be dried effectively. This solves the problem in the prior art that when a lot of medicines are placed in the medicine placement box 3, the medicines tend to accumulate in the medicine placement box 3, making it difficult for the accumulated medicines to contact the air inside the drying oven body 1, thus making it difficult to dry the accumulated medicines effectively, and thus affecting the drying effect of the medicines.

[0028] Furthermore, a rotating shaft 403 is fixedly installed at the output end of the motor 402. The rotating shaft 403 passes through the top of the support frame 401 and is rotatably connected to the support frame 401 through a bearing. The rotating frame 404 is fixedly installed at the bottom end of the rotating shaft 403.

[0029] By setting a rotating shaft 403, the motor 402 can drive the rotating frame 404 to rotate via the rotating shaft 403.

[0030] Furthermore, a limiting rod 407 is fixedly installed at the bottom of the carrier plate 406, and a rod hole 408 is opened at the bottom of the inner wall of the placement box 3. The limiting rod 407 moves through the rod hole 408, and a spring 409 surrounds the outer wall of the limiting rod 407.

[0031] The limiting rod 407 can limit the spring 409 and ensure the stability of the spring 409 during compression.

[0032] Furthermore, a support pad 5 is fixedly installed on the top of the carrier plate 406, and the support pad 5 is made of sponge.

[0033] The support pad 5 provides a buffering effect when the medicine is stirred and turned, preventing hard collisions between the medicine and the carrier plate 406, which could cause the medicine to break and affect its normal use.

[0034] Furthermore, support slide plates 6 are fixedly installed on both sides of the placement box 3, and support grooves 7 are opened on the inner side of the frame 2, with the support slide plates 6 and support grooves 7 slidably connected.

[0035] Among them, by setting the support slide plate 6 and the support slide groove 7, the placement box 3 can play a certain supporting and limiting role.

[0036] Furthermore, the front of the drying oven body 1 is hinged with a door 8, and a support block 9 is fixedly installed at the bottom of the drying oven body 1.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
