Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine processing, and specifically to a freeze-drying device for the production and processing of traditional Chinese medicine. Background Art

[0002] In the processing of traditional Chinese medicine, freeze-drying technology is a very important link. A traditional Chinese medicine freeze-dryer is a device that freezes and vacuum-dries traditional Chinese medicine or traditional Chinese medicine decoctions. In the processing of traditional Chinese medicine, freeze-drying technology can effectively retain the active ingredients in traditional Chinese medicine, thereby improving the efficacy of traditional Chinese medicine. The traditional Chinese medicine freeze-dryer pre-freezes the cut traditional Chinese medicine into a solid, and then in a vacuum environment, the solid ice in the traditional Chinese medicine can be directly sublimated into gas and evaporated, retaining the active ingredients in the traditional Chinese medicine, increasing stability, and facilitating storage and transportation at room temperature.

[0003] When the existing freeze-dryer takes and places medicine trays, in order to be convenient, a suspended track rack is used. The rack for placing medicine trays is moved out by driving a chain and a sprocket by a motor. It seems convenient, but in fact, it just transfers the taking and placing of the medicine tray from inside the freeze-dryer to outside the freeze-dryer. Moreover, the suspended track rack needs to be supported by multiple columns, which not only occupies space but also affects the activity range of the staff, and there is a problem of exchanging one thing for another. Summary of the Invention

[0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide a freeze-drying device for the production and processing of traditional Chinese medicine to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides a freeze-drying device for the production and processing of traditional Chinese medicine, including a freeze-drying chamber, a number of medicine trays placed inside the freeze-drying chamber, a refrigeration system for providing low-temperature conditions for the freeze-drying chamber, a vacuum system for providing a vacuum environment for the freeze-drying chamber, and an automatic control system; a tray-taking part for neatly taking out a number of medicine trays is arranged at the opening of the freeze-drying chamber;

[0006] The tray-taking part is a turntable group for suspending a number of medicine trays and horizontally rotating out. The turntable group includes a rotating door rotatably connected to a vertical side of the opening of the freeze-drying chamber, a number of medicine tray suspensions fixedly connected to the inner side surface of the rotating door, and a movable frame group suspended at one end of each layer of medicine tray suspension;

[0007] The movable frame group is far from the rotating shaft end of the rotating door and can perform horizontal telescopic movement; the movable frame group includes a movable suspension slidably connected to the bottom surface of the medicine tray suspension and a movable tray suspended at the bottom surface of the movable suspension;

[0008] The tray-taking part is a tray-transfer group for supporting a number of medicine trays and horizontally moving them out. The tray-transfer group includes a flip door rotatably connected to the bottom side of the opening of the freeze-drying chamber, a medicine tray bracket slidably arranged inside the freeze-drying chamber, and a bracket-transfer group arranged on both sides of the medicine tray bracket; the bracket-transfer group includes a pull rope with one end fixedly connected to the upper end of the flip door and the other end in a coiled state and arranged below the flip door, a rope winding box for storing the coiled part of the pull rope, and a coil spring arranged inside the rope winding box; the middle section of the pull rope is hung on the inner end bottom wall of the medicine tray bracket, and the coil spring is coaxially connected to the coiled part of the pull rope.

[0009] When the lower rotating flip door drives the release of the coiled part of the pull rope and tightens the coil spring to store elastic potential energy, until the flip door is flattened, the medicine tray bracket loses the block of the flip door and winds the pull rope under the condition that the coil spring releases elastic potential energy, that is, the pull rope is used to pull the medicine tray bracket out of the freeze-drying chamber and place it on the flip door.

[0010] As a further improvement of this technical solution, a support wheel group is arranged at the end of the rotating door far from its rotation axis, a number of reinforcing ribs are arranged at equal intervals vertically on the outer side surface of the rotating door, the distance between the inner end corner of the medicine tray suspension and the rotation axis of the rotating door is equal to the inner width of the opening of the freeze-drying chamber, a clamping strip is arranged on the bottom surface of the end of the medicine tray suspension far from the rotation axis of the rotating door, and a supporting strip is arranged on the inner wall of the rotating door and below each layer of the medicine tray suspension. The movable suspension is inserted and slidable with the clamping strip and the supporting strip at the same horizontal height.

[0011] As a further improvement of this technical solution, the longitudinal section of the clamping strip is L-shaped and a locking port is opened on its vertical side surface. Oblique ports are arranged on both sides of the inner port of the locking port, and the distance between the outer ports of the two oblique ports is greater than the inner width of the locking port. A locking block and an elastic sheet are embedded on the side end surface of the movable suspension facing the freeze-drying chamber. When the movable suspension is squeezed into the range below the medicine tray suspension, the locking block turns outwards under the elastic force of the elastic sheet and is clamped and matched with the locking port.

[0012] As a further improvement of this technical solution, an unlocking pin that can be inserted into the outer port of the locking port is arranged on the inner wall of the freeze-drying chamber. When the rotating door is closed, the medicine tray suspension is closest to the inner wall of the freeze-drying chamber, and the unlocking pin is correspondingly inserted into the locking port, thereby squeezing the locking block out of the inner port of the locking port.

[0013] As a further improvement of this technical solution, the ends of the clamping strip and the supporting strip close to the rotation axis of the rotating door are closed and an insertion rod is inserted. Insertion holes for inserting the insertion rod are opened at both corners of the long side of the movable suspension, and a spring is sleeved outside the insertion rod and outside the movable suspension.

[0014] As a further improvement of this technical solution, the length of the insertion rod is greater than the width of the movable suspension. A groove is opened at the side end of the movable suspension facing the inner wall of the freeze-drying chamber and close to the corner. The locking block is placed inside the port of the groove and is rotatably connected, and the elastic sheet is placed between the groove and the locking block.

[0015] As a further improvement of the technical solution, a plurality of card slots are provided in the width direction of the top surface of the movable disk, and a plurality of insertion strips are equidistantly arranged in the width direction of the bottom surface of the movable suspension. The longitudinal section of the insertion strip is wider at the lower end and narrower at the upper end. The plurality of insertion strips correspond to and are adaptively inserted and matched with the plurality of card slots.

[0016] As a further improvement of the technical solution, a track wheel is connected to the bottom side wall of the medicine tray bracket through a pin. A plurality of track strips are fixedly connected to the inner bottom surface of the freeze-drying chamber. The track wheel is in rolling connection with the track strip.

[0017] As a further improvement of the technical solution, the track wheels on both sides are coaxially connected with winding wheels. The pull rope extending from the rope winding box bypasses the winding wheels and is then fixed to the upper end of the flip door. Through grooves are symmetrically provided at the bottom surface of the freeze-drying chamber and near the corners of its chamber opening. A support column is embedded at the rear end of the through groove. The pull rope bypasses the through groove above the support column and is wound around the central axis of the rope winding box. The upper end of the rope winding box is open and covers the through groove.

[0018] As a further improvement of the technical solution, sealing strips are provided on the inner walls around the chamber opening of the freeze-drying chamber. A plurality of sleeve rings are welded to the outer wall at the chamber opening of the freeze-drying chamber. A bolt is rotatably connected inside the sleeve ring. A bolt seat that is snap-fitted with the bolt is welded to the outer side surface of the rotating door.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. For the freeze-drying device for Chinese herbal medicine production and processing, through the arranged turntable group, a plurality of medicine trays are neatly taken out. By rotating and opening one end of the rotating door and using a plurality of medicine tray suspensions to support a plurality of medicine trays out of the freeze-drying chamber, the space occupation is saved and the site layout method is optimized.

[0021] 2. For the freeze-drying device for Chinese herbal medicine production and processing, through the movable frame group arranged at the side end where the medicine tray suspension is taken out, considering the rotation radius, by shortening the medicine tray suspension and arranging a movable movable frame group at its taken-out end, so as to hide the movable frame group when taking out, and at the same time play a role in increasing the part lacking the medicine tray placement of the medicine tray suspension. Thus, both the internal space of the freeze-drying chamber is fully utilized and the normal taking and placing of the medicine trays are not hindered. Its design is ingenious and practical.

[0022] 3. For the freeze-drying device for Chinese herbal medicine production and processing, through the arranged lock block, elastic piece and unlocking pin, after the rotating door is closed and under the elastic force of the spring and when the unlocking pin pushes out the lock block and turns to the inclined opening on the right side, the movable suspension obtains a thrust and loses the limit and smoothly extends out below the medicine tray suspension, that is, the process of automatically unfolding in the freeze-drying chamber is completed, so as to open the medicine tray for freeze-drying.

[0023] 4. The freeze-drying device for the production and processing of traditional Chinese medicinal materials provides another way to take out the medicine tray. That is, by setting up a tray transfer group, the lower rotating flip door drives the release of the winding part of the pull rope, and the winding spring stores elastic potential energy. Until the flip door is flattened, the medicine tray bracket loses the block of the flip door and winds the pull rope under the release of the elastic potential energy of the winding spring. That is, the pull rope is used to pull the medicine tray bracket out of the freeze-drying chamber and place it on the flip door, saving space occupancy and optimizing the site layout method.

[0046] Please refer to Figures 1 - 13 As shown, the present invention provides a freeze-drying device for the production and processing of traditional Chinese medicines, including a freeze-drying chamber 100, several medicine trays 200 placed inside the freeze-drying chamber 100, a refrigeration system for providing low-temperature conditions for the freeze-drying chamber 100, a vacuum system for providing a vacuum environment for the freeze-drying chamber 100, and an automatic control system; the freeze-drying chamber 100 is the main place for freeze-drying traditional Chinese medicines, usually a sealed container, maintaining a low-temperature and vacuum environment inside to carry out the freezing and sublimation drying of traditional Chinese medicines; the refrigeration system is responsible for providing and maintaining the low-temperature environment inside the freeze-drying chamber, freezing the traditional Chinese medicines into solids at low temperatures to facilitate subsequent water sublimation; the vacuum system is used to create and maintain a vacuum environment during the freeze-drying process, which is the key condition for the water in traditional Chinese medicines to directly sublimate from a solid state to a gaseous state; the automatic control system is the core part of the freeze-dryer for traditional Chinese medicines, responsible for the automatic control of the entire freeze-drying process, including the setting and adjustment of parameters such as temperature, vacuum degree, heating power, etc.

[0047] Through the cooperation of the refrigeration system and the vacuum system, the water in traditional Chinese medicines is directly sublimated from a solid state to a gaseous state in a short time, thereby realizing the drying of traditional Chinese medicines. This drying method can retain the active ingredients and medicinal effects in traditional Chinese medicines to the greatest extent; the above are all prior arts and will not be elaborated here.

[0048] In addition, a tray-taking part for neatly taking out several medicine trays 200 is provided at the opening of the freeze-drying chamber 100; so as to quickly take and place the medicine trays 200, and it is not necessary to set up a track bracket for transporting the medicine trays 200 outside the freeze-drying chamber 100, saving the occupation of space and optimizing the site layout method.

[0049] The disk-taking part is a turntable group 300 that suspends a number of medicine trays 200 and rotates them horizontally. The turntable group 300 includes a rotating door 310 rotatably connected to a vertical side of the opening of the freeze-drying chamber 100, a number of medicine tray suspensions 320 fixedly connected to the inner side surface of the rotating door 310 by bolts or welding, and a movable frame group 330 is suspended at one end of each layer of the medicine tray suspension 320; that is, by rotating and opening one end of the rotating door 310, a number of medicine trays 200 are supported by a number of medicine tray suspensions 320 and rotated out of the freeze-drying chamber 100. At the same time, considering the rotation radius, by shortening the medicine tray suspension 320 and arranging a movable frame group 330 at its rotating end, the movable frame group 330 can be hidden when rotating out, and at the same time, it plays a role in increasing the part where the medicine tray 200 is not placed in the medicine tray suspension 320. Thus, both the internal space of the freeze-drying chamber 100 is fully utilized, and the normal taking and placing of the medicine trays 200 are not hindered. Its design is ingenious and practical.

[0050] Specifically, the movable frame group 330 is far from the rotating shaft end of the rotating door 310 and can perform horizontal telescopic movement; the movable frame group 330 includes a movable suspension 332 slidably connected to the bottom surface of the medicine tray suspension 320 and a movable disk 331 suspended from the bottom surface of the movable suspension 332; so that when the rotating door 310 is opened, the movable frame group 330 contacts the side wall of the freeze-drying chamber 100 and retracts into the bottom surface of the medicine tray suspension 320, without affecting the overall rotation in and out.

[0051] A support wheel group 311 is provided at the end of the rotating door 310 far from its rotating shaft, which is used to touch the ground to support the rotating door 310 to maintain a stable state when rotating out; a number of reinforcing ribs 312 are arranged at equal intervals vertically on the outer side surface of the rotating door 310, which are used to strengthen the overall strength of the rotating door 310, so as to suspend a number of medicine trays 200 inside the rotating door 310; the distance between the inner corner of the medicine tray suspension 320 and the rotating shaft of the rotating door 310 is equal to the inner width of the opening of the freeze-drying chamber 100, so that the medicine tray suspension 320 can be smoothly rotated out when the rotating door 310 rotates out.

[0052] Furthermore, a clamping strip 321 is provided on the bottom surface of one end of the medicine tray suspension 320 far from the rotating shaft of the rotating door 310, and a supporting strip 340 is provided on the inner wall of the rotating door 310 and below each layer of the medicine tray suspension 320. The movable suspension 332 is inserted and slidable with the clamping strip 321 and the supporting strip 340 at the same horizontal height, which is used to support the stable telescopic movement of the movable suspension 332.

[0053] It should be noted that the longitudinal section of the clamping strip 321 is L-shaped and a locking port 322 is opened on its vertical side surface. On both sides of the inner port of the locking port 322, inclined ports 3221 are provided, and the distance between the outer ports of the two inclined ports 3221 is greater than the inner width of the locking port 322.

[0054] The side end face of the movable suspension 332 facing the freeze-drying chamber 100 is embedded with a locking block 333 and a spring piece 3331. The spring piece 3331 is made of spring steel and bent into an open-mouth shape, such as a V shape or a U shape. When the movable suspension 332 is squeezed into the range below the medicine tray suspension 320, when the locking block 333 slides along the inner wall of the clamping strip 321 to the locking port 322, the locking block 333 turns outwards under the elastic force of the spring piece 3331 and is clamped and matched with the locking port 322, thereby realizing that the movable suspension 332 is limited and hidden below the medicine tray suspension 320; as Figure 9 shown, the inclined mouth 3221 on the left is used to limit the deflection angle of the locking block 333, and the inclined mouth 3221 on the right is used to guide the locking block 333 to smoothly slide out of the locking port 322 when the movable suspension 332 extends out.

[0055] Furthermore, one end of the clamping strip 321 and the supporting strip 340 close to the rotating shaft of the rotating door 310 is closed and inserted with a plug rod 323. Insertion holes 3322 for inserting the plug rod 323 are opened at both corners of the long side of the movable suspension 332. A spring 334 is sleeved outside the plug rod 323 and outside the movable suspension 332. The plug rod 323 is used to ensure that the spring 334 remains in a contracted state when being compressed;

[0056] An unlocking pin 335 that can be inserted into the outer port of the locking port 322 is arranged on the inner wall of the freeze-drying chamber 100. When the rotating door 310 is closed, the medicine tray suspension 320 is closest to the inner wall of the freeze-drying chamber 100, and the unlocking pin 335 is correspondingly inserted into the locking port 322, thereby squeezing and pushing the locking block 333 out of the inner port of the locking port 322; that is, after the rotating door 310 is closed, under the elastic force of the spring 334 and when the unlocking pin 335 pushes out the locking block 333 and turns to the inclined mouth 3221 on the right, the movable suspension 332 obtains a thrust and loses its limit and smoothly extends out below the medicine tray suspension 320, that is, the process of automatically unfolding in the freeze-drying chamber 100 is completed, so that the medicine tray can be opened for freeze-drying.

[0057] Furthermore, the length of the plug rod 323 is greater than the width of the movable suspension 332, so that the spring 334 has a space to be compressed; a groove 3323 is opened at the side end of the movable suspension 332 facing the inner wall of the freeze-drying chamber 100 and close to the corner. The locking block 333 is placed inside the port of the groove 3323 and is rotatably connected. The spring piece 3331 is placed between the groove 3323 and the locking block 333, that is, the elastic force of the spring piece 3331 is used to keep the state of pushing the locking block 333 out of the groove 3323 until the locking block 333 coincides with the locking port 322 and an automatic locking action occurs.

[0058] Further, a plurality of card slots 3311 are formed in the width direction of the top surface of the movable plate 331, and a plurality of insertion strips 3321 are equidistantly arranged in the width direction of the bottom surface of the movable suspension 332. The longitudinal section of the insertion strip 3321 is wider at the lower end and narrower at the upper end, such as a dovetail groove, an inverted T groove, or a water droplet groove. The plurality of insertion strips 3321 correspond to and are adaptively inserted and mated with the plurality of card slots 3311, so as to suspend the movable plate 331 below the movable suspension 332.

[0059] It should be noted that the present invention also provides another way to take out the medicine tray 200. The tray taking part is a tray moving group 400 for supporting a plurality of medicine trays 200 and horizontally moving them out. The tray moving group 400 includes a turning door 410 rotatably connected to the bottom side of the opening of the freeze-drying chamber 100, a medicine tray bracket 420 slidably arranged inside the freeze-drying chamber 100, and a bracket moving group 430 arranged on both sides of the medicine tray bracket 420. That is, by turning the turning door 410 downward to open it, and then using the bracket moving group 430 to take out the medicine tray bracket 420 and slide it out of the freeze-drying chamber 100.

[0060] The bracket moving group 430 includes a pull rope 431 with one end fixedly connected to the upper end of the turning door 410 by bolts or welding and the other end in a wound state and arranged below the turning door 410, a rope winding box 432 for storing the wound part of the pull rope 431, and a torsion spring 433 arranged inside the rope winding box 432. The middle section of the pull rope 431 is hung on the inner end bottom wall of the medicine tray bracket 420, and the torsion spring 433 is coaxially connected to the wound part of the pull rope 431.

[0061] When the turning door 410 is turned downward to drive the release of the wound part of the pull rope 431 and tighten the torsion spring 433 to store elastic potential energy, until the turning door 410 is flattened, the medicine tray bracket 420 loses the block of the turning door 410 and winds the pull rope 431 under the condition that the torsion spring 433 releases elastic potential energy. Since the medicine tray bracket 420 will be blocked by the inclined turning door 410 when the turning door 410 is not flattened, the pull rope 431 will be stretched and released, and the release of the wound pull rope 431 will drive the coaxial torsion spring 433 to wind and store energy. That is, the pull rope 431 is used to pull the medicine tray bracket 420 out of the freeze-drying chamber 100 and place it on the turning door 410.

[0062] Further, a track wheel 421 is connected to the bottom side wall of the medicine tray bracket 420 by a pin, and a plurality of track bars 422 are fixedly connected to the inner bottom surface of the freeze-drying chamber 100 by bolts. The track wheel 421 is in rolling connection with the track bars 422 to ensure the stable movement in and out of the medicine tray bracket 420.

[0063] The track wheels 421 on both sides are coaxially connected with a reel 423. The pulling rope 431 extending from the rope winding box 432 bypasses the reel 423 and is then fixed to the upper end of the flipping door 410. Through grooves 101 are symmetrically formed at the bottom surface of the freeze-drying chamber 100 and near the corners of its chamber opening for the pulling rope 431 to pass through. A supporting column 434 is embedded at the rear end of the through groove 101. The pulling rope 431 bypasses the through groove 101 above the supporting column 434 and is wound around the central axis of the rope winding box 432. The upper end of the rope winding box 432 is open and covers the through groove 101 to seal the internal environment of the freeze-drying chamber 100.

[0064] Sealing strips 110 are provided on the inner walls around the chamber opening of the freeze-drying chamber 100 to seal the internal environment of the freeze-drying chamber 100 when the door is closed. A plurality of collar rings 120 are welded to the outer wall at the chamber opening of the freeze-drying chamber 100. A door bolt 130 is rotatably connected inside the collar ring 120. A bolt seat 313 that is snap-fitted with the door bolt 130 is welded to the outer side surface of the rotating door 310. Similarly, the outer wall of the flipping door 410 is also provided with the structure of the door bolt 130 and the bolt seat 313 to lock the flipping door 410. In addition, a pulling frame 411 is welded to the outer wall of the flipping door 410 to facilitate pulling open the flipping door 410. At the same time, the pulling frame 411 is used to support on the ground to support the medicine tray bracket 420 to slide onto the flipping door 410.

[0065] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
