Description

Technical Field

[0001] The utility model relates to the technical field of COFs material production, in particular to a vacuum freeze dryer with a layered structure for producing COFs materials. Background Art

[0002] COFs materials, Chinese name covalent organic framework materials, are a new type of crystalline porous polymer materials composed of organic molecules connected by covalent bonds. The core of COFs is the word "porous". Therefore, to understand what COFs are, we must first have a basic understanding of porous materials, which are a type of functional materials.

[0003] In the production process of COFs materials, they need to be vacuum freeze-dried. Most of the existing vacuum freeze dryers do not have the function of stratification, which results in the COFs materials being poured into the machine during the vacuum freeze-drying operation. When a large amount of COFs materials are vacuum freeze-dried in the same box, it is easy to cause moisture residue at the position where the COFs materials are condensed together, resulting in uneven heating of the COFs materials and the inability of the dryer to evenly dry the COFs materials, which is inconvenient for staff to use. For this reason, we propose a vacuum freeze dryer for COFs material production with a layered structure. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a vacuum freeze dryer for producing COFs materials with a layered structure, which is used to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A vacuum freeze dryer for producing COFs materials with a layered structure comprises a box body, a support assembly is arranged inside the box body, a connection block is arranged above the support assembly, a placement assembly is arranged on the top of the connection block, a vacuum freeze dryer body is arranged on one side of the box body, a conveying assembly is arranged on the top of the vacuum freeze dryer body, a motor is arranged on one side of the box body, a rotating shaft is fixedly connected to the output end of the motor, the rotating shaft extends to the inside of the box body, and a reciprocating assembly is arranged outside the rotating shaft.

[0007] Preferably, a support plate is fixedly connected to one side of the box body, and the motor is fixedly installed above the support plate. The support plate is provided so that the motor will not idle when working.

[0008] Preferably, the support assembly includes telescopic sleeves fixedly mounted at the four corners of the bottom inner wall of the box body, the interiors of the four telescopic sleeves are slidably connected with telescopic rods, and the bottom of the connecting block is fixedly mounted on the top of the telescopic rod. By setting up the support assembly, the plug-in box can be made more stable when moving.

[0009] Preferably, the placement component comprises three equally spaced plug-in boxes fixedly mounted on the top of the connection block, and drawers are movably plugged into the interiors of the plug-in boxes. The COFs material can be placed by means of the placement component.

[0010] Preferably, a handle is fixedly connected to one side of the drawer, and the handle is made of rubber. By providing the rubber handle, the comfort of the staff when holding the handle is improved.

[0011] Preferably, the conveying assembly includes a telescopic tube connected to the output end of the vacuum freeze dryer body, the top of the telescopic tube is connected to a first connecting tube, the outside of the first connecting tube is connected to three second connecting tubes distributed at equal distances, and the other ends of the three second connecting tubes are connected to the inside of the corresponding plug-in box. By setting the telescopic tube, the plug-in box can be telescoped when moving.

[0012] Preferably, the reciprocating assembly includes three equidistantly distributed cams fixedly sleeved on the outside of the rotating shaft, and a trapezoidal block is fixedly connected to the bottom of the connecting block. The trapezoidal block is adapted to the cam, and the reciprocating assembly is set up to make the plug-in box move reciprocatingly up and down.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Refer to Figure 1-3 A vacuum freeze dryer for producing COFs materials with a layered structure comprises a box body 1, wherein a support assembly is arranged inside the box body 1, wherein the support assembly comprises telescopic sleeves 6 fixedly mounted at the four corners of the bottom inner wall of the box body 1, wherein the four telescopic sleeves 6 are slidably connected with telescopic rods 7 inside, wherein the bottom of a connecting block 8 is fixedly mounted on the top of the telescopic rod 7, and through the setting of the support assembly, a plug-in box 9 can be made more stable when moving, a connecting block 8 is arranged above the support assembly, and a placement assembly is arranged on the top of the connecting block 8, wherein the placement assembly comprises three plug-in boxes 9 fixedly mounted on the top of the connecting block 8 and distributed at equal distances, wherein drawers 10 are movably connected inside the plug-in boxes 9, and COFs materials can be placed through the setting of the placement assembly, and a handle 11 is fixedly connected to one side of the drawer 10, wherein the handle 11 is made of rubber material, and through the setting of the rubber handle 11, the comfort of the staff when holding the handle 11 is improved.

[0020] Specifically, a vacuum freeze dryer body 12 is provided on one side of the box body 1, and a conveying assembly is provided on the top of the vacuum freeze dryer body 12. The conveying assembly includes a telescopic tube 13 connected to the output end of the vacuum freeze dryer body 12, and the top of the telescopic tube 13 is connected to a first connecting tube 14. The outside of the first connecting tube 14 is connected to three second connecting tubes 15 distributed at equal distances. The other ends of the three second connecting tubes 15 are connected to the inside of the corresponding plug-in box 9. By setting the telescopic tube 13, the plug-in box 9 can be telescoped when moving.

[0021] Specifically, a motor 3 is provided on one side of the box body 1, and a support plate 2 is fixedly connected to one side of the box body 1. The motor 3 is fixedly installed above the support plate 2. The support plate 2 is set so that the motor 3 will not idle when working. The output end of the motor 3 is fixedly connected to a rotating shaft 4, and the rotating shaft 4 extends to the inside of the box body 1. A reciprocating component is provided on the outside of the rotating shaft 4. The reciprocating component includes three equidistantly distributed cams 5 fixedly sleeved on the outside of the rotating shaft 4. The bottom of the connecting block 8 is fixedly connected to a trapezoidal block 16, which is adapted to the cam 5. The reciprocating component can make the plug-in box 9 move up and down reciprocatingly.

[0022] When in use: When the COFs material needs to be vacuum freeze-dried during the production process, first put the COFs material in the drawer 10, push the drawer 10 into the plug-in box 9, and the COFs material can be layered and vacuum freeze-dried through the three drawers 10. By starting the vacuum freeze-drying machine body 12, the output end of the vacuum freeze-drying machine body 12 can perform vacuum freeze-drying operations on the COFs material in the plug-in box 9 through the telescopic tube 13, the first connecting tube 14 and the second connecting tube 15. By starting the motor 3, the output end of the motor 3 drives the rotating shaft 4 and the cam 5 to rotate. When the convex end of the cam 5 contacts the trapezoidal block 16, the trapezoidal block 16, the connecting block 8 and the plug-in box 9 can be lifted up and moved upward. When the convex end of the cam 5 is separated from the trapezoidal block 16, the trapezoidal block 16, the connecting block 8 and the plug-in box 9 can be lifted up and moved upward. When the drawer 10 is in the state of being dried, the trapezoidal block 16, the connecting block 8 and the plug-in box 9 move downward due to gravity, and slide inside the telescopic sleeve 6 through the telescopic rod 7, so that the plug-in box 9 is more stable when moving. The plug-in box 9 can be reciprocated up and down by rotating the cam 5, so that the COFs material inside the drawer 10 vibrates. The above structure is convenient for the staff to perform vacuum freeze-drying operation on the COFs material. During operation, the COFs material can be classified into layers. At the same time, when the COFs material is in the vacuum freeze-drying operation, the COFs material vibrates, which avoids the problem that moisture residue is easy to appear at the position where the COFs material is condensed together, resulting in uneven heating of the COFs material and the inability of the dryer to dry the COFs material evenly, which greatly facilitates the use of the staff.
