Technical Field

[0001] This application relates to the field of vacuum freeze-drying equipment, and particularly to an adjustable vacuum freeze-drying chamber. Background Art

[0002] Vacuum freeze-drying technology is a technology that freezes substances in a liquid or solution state at low temperature and then removes the moisture in them by sublimation under vacuum conditions. This technology is also known as freeze-drying technology or lyophilization technology and is widely used in the drying technology of fields such as food, medicine, and chemical industry.

[0003] Traditional vacuum freeze-drying chambers usually have a fixed layered plate structure with fixed functionality and cannot be adjusted according to actual needs. Currently, in order to solve the drying problems of different materials and process requirements, it is usually necessary to replace vacuum freeze-drying chambers of different models, which not only increases costs but also reduces production efficiency.

[0004] In view of the problems such as fixed structure, single function, and poor adaptability existing in the above-mentioned traditional vacuum freeze-drying chamber, an adjustable vacuum freeze-drying chamber is proposed to solve these problems. Utility Model Content

[0006] In summary, this application provides the following technical solution: an adjustable vacuum freeze-drying chamber, including a vacuum chamber and four layered plates disposed in the vacuum chamber, and a lifting mechanism is arranged between adjacent layered plates;

[0007] The lifting mechanism includes a driving member and a connecting rod member for driving, wherein the driving member includes a cylinder fixed to the top of the vacuum chamber, and the piston rod end of the cylinder is fixedly connected to the uppermost layered plate;

[0008] The connecting rod member includes a guide rod fixedly installed on the bottom plate, a rectangular connecting block is fixedly installed on the side surface of the layered plate, a guide sleeve is fixedly installed through the connecting block, the guide sleeve is slidably connected to the guide rod, and the connecting rod member further includes a connecting bolt arranged outside the connecting block and a guide frame slidably connected to the connecting bolt.

[0009] By adopting the above technical solution, the layered plate is connected to the freeze-drying chamber through the lifting mechanism to realize the lifting movement of the layered plate.

[0010] Furthermore, a bottom plate for supporting the lowermost one of the four layered plates is fixedly installed at the bottom of the vacuum chamber, and the lowermost one of the four layered plates is fixedly connected to the bottom plate.

[0011] By adopting the above technical solution, the bottom position of the layered plate is fixed and the connection is stable.

[0012] Furthermore, a connection seat is fixedly installed on the layered plate, and the end of the piston rod of the cylinder is fixedly connected to the connection seat.

[0013] By adopting the above technical solution, the connection stability between the layered plate and the cylinder can be improved.

[0014] Furthermore, a limit block is fixedly installed on the top end of the guide rod, and the diameter of the limit block is larger than the inner diameter of the guide sleeve.

[0015] By adopting the above technical solution, it is possible to prevent the layered plate connected to the guide sleeve from slipping out of the guide rod.

[0016] Furthermore, the connecting bolt includes a rod body in the shape of a bolt and an end cap, and the end cap is fixed to one end of the rod body away from the connecting block.

[0023] By adopting the above technical solution, it is convenient to observe the state of the material on the front surface of the vacuum chamber.

[0024] The adjustable vacuum freeze-drying chamber enables the relative movement between the layered plates by setting the connection bolts and the guide frames to slide relative to each other, and the guide sleeves to slide relative to the guide rods. This allows the layered plates to move synchronously downward by hanging, and after coming into contact and abutting during downward movement, they can be adjusted to approach layer by layer, improving the adaptability of the vacuum moving rod chamber and meeting the drying requirements of different materials. By setting a clamping frame between the layered plates, it is convenient to clamp and connect the bottle caps and the medicine bottles, enhancing the practicality of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Please refer to Figure 1 , an adjustable vacuum freeze-drying chamber in this embodiment includes a vacuum chamber 1 and layered plates 5 disposed inside the vacuum chamber 1. The number of the layered plates 5 is four, but is not limited to four and can be additionally increased. A lifting mechanism is provided between adjacent layered plates 5 for adjusting the distance between the layered plates 5.

[0031] It should be supplemented that the vacuum chamber 1 adopts a cylindrical inner chamber and exchanges heat through copper pipes. At the same time, a bottom plate 2 for supporting the lowermost one of the four layered plates 5 is fixedly installed at the bottom of the vacuum chamber 1, and the lowermost one of the four layered plates 5 is fixedly connected to the bottom plate 2.

[0032] In the present application, four layered plates 5 are distributed in the vacuum chamber 1, and the four layered plates 5 are driven by the lifting mechanism to move relative to each other to change the distance, so that the adapted vacuum freeze-drying chamber can adaptively adjust and seal bottles for different materials.

[0033] Please refer to Figure 1-2In this embodiment, the lifting mechanism includes a driving member and a connecting rod member, wherein the driving member includes a cylinder 12 fixed to the top of the vacuum chamber 1, and the piston rod end of the cylinder 12 is fixedly connected to the top layer plate 5, and can be pushed by the cylinder 12 to make the top layer plate 5 move toward the bottom plate 2 to adjust the spacing;

[0034] It is worth noting that a connecting seat 13 is fixedly mounted on the topmost layered plate 5 , and the end of the piston rod of the cylinder 12 is fixedly connected to the connecting seat 13 .

[0035] The connecting rod member includes a guide rod 3 fixedly mounted on the bottom plate 2 , a rectangular connecting block 6 fixedly mounted on the side of the layered plate 5 , a guide sleeve 7 passing through and fixedly mounted on the connecting block 6 , and the guide sleeve 7 is slidably connected to the guide rod 3 .

[0036] The relative sliding between the guide sleeve 7 and the guide rod 3 ensures that the vertical distribution between the upper and lower adjacent layered plates 5 is accurate.

[0037] It should be noted that a limit block 4 is fixedly mounted on the top end of the guide rod 3 , and the diameter of the limit block 4 is larger than the inner diameter of the guide sleeve 7 .

[0038] Such a design enables the guide sleeve 7 to be blocked by the stop block 4 when sliding relative to the guide rod 3 , thereby preventing the plurality of layered plates 5 from being separated from the guide rod 3 .

[0039] See also Figure 2-3 The connecting rod also includes a connecting bolt 10 arranged on the outside of the connecting block 6 and a guide frame 11 slidably connected to the connecting bolt 10. The connecting bolt 10 includes a bolt-shaped rod body 101 and an end cap 102. The end cap 102 is fixed on one end of the rod body 101 away from the connecting block 6, and is used to limit the guide frame 11 from being separated from the rod body 101.

[0040] In a specific implementation, the rod bodies 101 on the outer sides of two adjacent layered plates 5 can slide relative to the hollow groove in the middle of the guide frame 11 , so that the adjacent layered plates 5 can move relative to each other.

[0041] In the present application, by installing a connecting bolt 10 on the outer side of the connecting block 6 and hanging and connecting the guide frame 11 between two vertically adjacent connecting bolts 10, a plurality of continuously hung layer plates 5 can be moved synchronously to realize lifting and lowering, and when the adjacent layer plates 5 are in contact with each other, the layer plate 5 that stops moving due to contact with the material can complete the sequential contact with the layer plate 5 adjacent to the upper side;

[0042] That is to say, it can be understood that the lowermost suspended layered plate 5 and the lowermost layered plate 5 approach and contact each other to lift the lowermost suspended layered plate 5 with the material, so that the layered plates 5 above the suspended layered plate 5 approach each other relative to the suspended layered plate 5, and the above process is repeated until all the layered plates 5 approach and contact each other with the material.

[0043] It can be understood that a heat conduction tube 8 is fixedly installed on the side surface of the layered plate 5. The heat conduction tube 8 penetrates through the layered plate 5 and is filled with silicone grease for conducting heat, so as to heat and cool the layered plate 5. A metal bellows 9 connected in series between several layered plates 5 is communicated with the outside of the heat conduction tube 8.

[0044] Please refer to Figure 2-3 In this embodiment, the connection mode of the rod body 101 relative to the connection block 6 can be a fixed connection, or a bolt connection can also be adopted, which is convenient for adjustment and disassembly.

[0045] In this embodiment, the guide frames 11 between the continuously adjacent upper and lower layered plates 5 are arranged in a staggered manner front and back to reduce interference caused by mutual movement.

[0046] Please refer to Figure 1-3 , in this implementation, a transparent door panel 14 for closing is also hinged on the front surface of the vacuum chamber 1. A handle 15 threadedly connected to the vacuum chamber 1 is rotatably installed at one end of the transparent door panel 14 for closing the opening on the front surface of the vacuum chamber 1.

[0047] It should be noted that a groove 16 is also formed on the lower surface of the layered plate 5. A clamping frame 17 for clamping the bottle cap is fixedly installed on the groove 16. The clamping frame 17 is in a circular ring shape corresponding to the bottle cap of the material, and the bottle cap is pre-fixed by extrusion.

[0048] In this application, by setting the clamping frame 17, during the descending process of the layered plate 5, the medicine bottle cap pre-fixed on the clamping frame 17 can be clamped and connected with the medicine bottle on the lower layered plate 5, so as to avoid the applicable limitation due to the fixed structure of the layered plate 5.

[0049] The working principle of the above embodiment is:

[0050] By placing the material above the layered plate 5 and pre-fixing the medicine bottle cap at the position below the layered plate 5 through the clamping frame 17, after the processing in the vacuum chamber 1 is completed, by controlling the movement of the cylinder 12, the cylinder 12 drives the uppermost layered plate 5 connected to its power end to move downward. At this time, the second and third layered plates 5 suspended by the guiding frame 11 are lowered synchronously with the uppermost layered plate 5. After the medicine bottle cap at the bottom of the lowermost layered plate 5 and the medicine bottle on the surface of the layered plate 5 on the bottom plate 2 are clamped with each other, the relative positions of the two lowermost layered plates 5 are restricted. Under the continuous push of the upper cylinder 12, the guiding frame 11 outside the second layered plate 5 slides relative to the rod body 101 of the connecting bolt 10, so that the second layered plate 5 repeats the above process downward until the caps and bottle bodies between the four layered plates 5 are all clamped, and the adjustment processing is completed.
