Description

Technical Field

[0001] The invention belongs to the technical field of graphene manufacturing, in particular to a graphene oxide vacuum freeze dryer. Background Art

[0002] Graphene oxide is the oxide of graphene, generally represented by GO, and its color is brown-yellow. Common products on the market are powder, flake and solution. After oxidation, the number of oxygen-containing functional groups on it increases, making its properties more active than graphene. It can improve its own properties through various reactions with oxygen-containing functional groups. When freeze-drying and powdering graphene oxide, the freeze-dried graphene oxide is generally crushed manually after freeze-drying. However, manual crushing will cause the freeze-dried graphene oxide to deteriorate due to long-term contact with air, thereby causing a waste of resources. Therefore, the freeze-dried graphite oxide needs to be crushed under vacuum conditions.

[0003] However, existing devices often have poor sealing performance during the processing and stirring process, which allows external air to enter the interior of the device, destroying the vacuum state inside the device, causing the broken graphene oxide to slowly react with the incoming gas, posing a risk of deterioration. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a graphene oxide vacuum freeze dryer, which solves the problem that the existing devices often have poor sealing performance during the processing and stirring process, thereby allowing external air to enter the interior of the device and destroying the vacuum state inside the device, causing the broken graphene oxide to slowly react with the entering gas, posing a risk of deterioration.

[0005] The technical solution adopted by the present invention to solve its technical problems is: the graphene oxide vacuum freeze dryer described in the present invention comprises a vacuum pulverizer, and the left and right sides of the outer surface of the vacuum pulverizer are symmetrically provided with feeding boxes, the lower surface of the feeding box is fixedly connected with supporting legs, the upper surface of the feeding box is fixedly connected with a supporting frame, and the middle part of the inner wall of the supporting frame is fixedly connected with an external rotating machine, the vacuum pulverizer comprises a main shell, and the left and right sides of the upper surface of the main shell are symmetrically provided with vacuum pumps, a pulverizing device is arranged at the axis inside the main shell, the upper part of the inner wall of the main shell is rotatably connected with a connecting sleeve, and the lower part of the inner wall of the main shell is fixedly connected with a connecting sleeve. The left and right sides of the main shell are symmetrically provided with inclined slide rails, the lower surface of the main shell is fixedly connected with an extended bottom shell, the upper part of the inner wall of the extended bottom shell is rotatably connected with an inner rotating drum, a discharging device is arranged at the axis center of the lower part of the inner wall of the extended bottom shell, the inner rotating drum comprises a rotating ring shell, the lower surface of the rotating ring shell is fixedly connected with an external rotating sleeve, the left and right sides of the inner wall of the rotating ring shell are provided with adapting openings, the lower part of the inner wall of the rotating ring shell is fixedly connected with an inclined circular ring, before using the device, the feeding work is first carried out through the feeding boxes on both sides, and the graphene oxide solid particles slide into the interior of the main shell through the inclined slide rails. At this time, since the inner rotating drum is in Figure 2 In the state shown, the adapter ports on both sides of the rotating ring shell are connected to the bottom end of the inclined slide rail, so the graphene oxide solid particles will enter the inner wall of the rotating ring shell, that is, the upper surface of the inclined ring, through the adapter ports. After the feeding is completed, the bottom of the external rotating sleeve is rotated first, and the graphene oxide solid particles on the upper surface of the inclined ring fall into the bottom of the inner wall of the main shell under the action of centrifugal force. The rotating ring shell rotates along the inner wall of the main shell, and the rotating ring shell is relatively Figure 1 After the position shown is rotated ninety degrees clockwise, the adapter port is offset from the bottom end of the inclined slide rail, and the adapter port is blocked by the inner wall of the main shell, completing the preparation work. Although the device adopts the method of feeding from the outside for feeding, it has a related layered structure and can put the main shell body in a relatively sealed closed state by rotating the external rotating sleeve. In this way, the device will not have the problem of loose closure of the opening due to the related opening, causing the device to leak.

[0006] Preferably, the crushing device includes a vertical hollow rod, the inner wall of the vertical hollow rod is slidably connected with an adaptive insertion rod, the upper part of the outer surface of the vertical hollow rod is sleeved with a tension spring, the lower part of the outer surface of the vertical hollow rod is evenly provided with rotating shaft rods, the outer surface of the rotating shaft rods is evenly provided with small elastic frames, the top end of the small elastic frames is rotatably connected with rolling rods, the top end of the rotating shaft rods is rotatably connected with auxiliary guide wheels, and the upper surface of the auxiliary guide wheels is rotatably connected with an interlayer slide plate. Before the crushing work is carried out, first use the air extractors on both sides to pump out the air inside the main shell, so that the inside of the main shell remains in a relatively vacuum state. Then start the external rotating machine directly above, and control the vertical hollow rod to rotate self by means of a connecting sleeve. The vertical hollow rod drives the rotating shaft rods at the bottom to perform circular motion. Because in the normal state, the rolling rods are squeezed against the upper part of the inner wall of the main shell under the elastic force of the small elastic frames, and under the rolling action of the auxiliary guide wheels, the rotating shaft rods revolve around the vertical hollow rod as the axis and rotate self around their own central axes at the same time. Therefore, the rolling rods on the outer surface of each rotating shaft rod will crush the graphene oxide solid particles directly below. During the process of crushing graphene oxide solids, this device uses rolling rods that can be automatically adjusted to replace the rotating shaft rods to squeeze the outer surface of the graphene oxide solids, avoiding the problems of excessive rolling of the rotating shaft rods on the graphene oxide solids or insufficient crushing of the graphene oxide solids due to the too large distance between the rotating shaft rods and the bottom surface of the main shell. At the same time, it also avoids the cumbersome detection procedures such as debugging the rotating shaft rods.

[0007] Preferably, the number of the rotating shaft rods is four. One end of the rotating shaft rod close to the vertical hollow rod is fixedly connected with the lower part of the outer surface of the vertical hollow rod. The bottom end of the vertical hollow rod is rotatably connected with the center of the upper surface of the extended bottom shell. The outer surface of the auxiliary guide wheel is in rolling connection with the upper surface of the extended bottom shell. The upper surface of the interlayer slide plate is slidably connected with the upper part of the inner wall of the main shell. The top end of the vertical hollow rod extends to the outside of the main shell. The outer surface of the vertical hollow rod is rotatably connected with the center of the upper part of the inner wall of the main shell. The outer surface of the vertical hollow rod is fixedly connected with the center of the lower part of the inner wall of the connecting sleeve. After a period of rolling work, the graphene oxide solid particles are broken into smaller powders, showing the finished product effect. At this time, cover the bottom of the extended bottom shell with a sealed container, open the bottom of the extended bottom shell, and the rolled graphene oxide powder will fall into the inside of the container under the action of gravity to obtain the product.

[0008] Preferably, the side surface of the inner rotating cylinder is slidably connected to the lower part of the inner wall of the main housing. The bottom end of the external rotating sleeve extends to the outside of the extended bottom housing. The outer surface of the external rotating sleeve is slidably connected to the inner wall of the extended bottom housing. The bottom of the outer surface of the inclined slide rail is fixedly connected to one side of the inner wall of the main housing. The top end of the inclined slide rail extends into the feeding box. The top end of the tension spring is fixedly connected to the top end of the vertical hollow rod. The bottom end of the tension spring is slidably connected to the center of the upper surface of the main housing. Since the device has no relevant external openings, it has strong stability during operation. Moreover, the external rotating motor is not directly connected to the vertical hollow rod. Therefore, even if the outer surface of the output shaft loosens from the inner wall of the connecting sleeve during the rotation of the external rotating motor, there will be no problems such as air leakage destroying the vacuum state inside the device.

[0009] Preferably, the discharging device includes an upper fixed disk. Through holes are evenly formed in the inner wall of the upper fixed disk. A rotating bottom disk is rotatably connected to the lower surface of the upper fixed disk. A plug-in torque rod is fixedly connected to the center of the inner wall of the rotating bottom disk. Through-hole grooves are evenly arranged on the inner wall of the rotating bottom disk. The bottom end of the plug-in torque rod is fixedly connected to a bottom sleeve. A conical inclined block is fixedly connected to the outer surface of the bottom sleeve. The side surface of the upper fixed disk is fixedly connected to the upper part of the inner wall of the extended bottom housing. The side surface of the rotating bottom disk is rotatably connected to the inner wall of the extended bottom housing. The upper part of the outer surface of the plug-in torque rod is rotatably connected to the center of the inner wall of the upper fixed disk. The lower surface of the conical inclined block is fixedly connected to the lower part of the inner wall of the extended bottom housing. During the material taking process of a general device, it is usually necessary to open relevant openings, which further leads to poor sealing performance of the device. When the device opens the opening, the graphene oxide solid powder at the opening will come into contact with a large amount of external air. At this time, the graphene oxide solid powder will deteriorate, which seriously affects the quality of the product. By rotating the internal plug-in torque rod of this device, the through holes are connected to the through-hole grooves, and the graphene oxide solid powder on the upper surface of the upper fixed disk falls into the sealed container directly below through the through holes. Since the opening of this device is in the process of being opened, the graphene oxide solid powder is still in a state of being isolated from the external gas, so it will not react with the air and deteriorate, and the quality of the product is more guaranteed.

[0010] Preferably, the adaptation plug rod includes a connecting long rod. The top end of the outer surface of the connecting long rod is evenly provided with side-positioned insertion blocks. The bottom end of the connecting long rod is fixedly connected with a spherical half-shell sleeve. The inner wall of the spherical half-shell sleeve is evenly provided with arc-shaped insertion strips. After being rolled, the oxidized graphene solid particles will fall out of the inside of the main shell through the through-hole and the through-port groove. However, in the working state, the upper fixed plate and the rotating chassis have an initial rotation angle. Therefore, at this time, the through-hole and the through-port groove are staggered with each other, and the whole discharging device cannot be passed through. So the discharging device can keep the main shell and the extended bottom shell in a relatively sealed state during the working process. After the work is completed, it is necessary to discharge the oxidized graphene solid particles. At this time, the connecting long rod is pressed down through the side-positioned insertion blocks on the outside of the connecting long rod. The arc-shaped insertion strips on the inner wall of the spherical half-shell sleeve are adaptively clamped with the upper surface of the inserting torque rod. Then the side-positioned insertion block is rotated. The connecting long rod rotates the inserting torque rod through the spherical half-shell sleeve. During the rotation of the inserting torque rod, the lower rotating chassis is pulled to rotate. During the rotation of the rotating chassis, the through-port groove and the through-hole will surely be in a state of being connected to each other. At this time, the oxidized graphene solid particles can fall into the sealed container directly below through the through-port groove and the through-hole, completing the collection state.

[0011] Preferably, the inner wall of the spherical half-shell sleeve is slidably connected with the upper surface of the inserting torque rod. The inner wall of the spherical half-shell sleeve is inserted with the top end of the inserting torque rod through the arc-shaped insertion strips. The outer surface of the side-positioned insertion block is clamped with the top of the inner wall of the vertical hollow rod. The top end of the side-positioned insertion block extends to the outside of the connecting sleeve. The outer surface of the side-positioned insertion block is slidably connected with the inner wall of the connecting sleeve. The outer surface of the connecting long rod is slidably connected with the inner wall of the vertical hollow rod. The cross-sectional area of the through-hole is larger than that of the through-port groove. During the rotation of the rotating chassis, the oxidized graphene solid powder will not directly pass through the through-hole and the through-port groove and fall into the container below. It will be discharged to the outside only after a period of grinding process between the upper fixed plate and the rotating chassis again. So the discharging device can play a role in re-rolling the oxidized graphene solid powder, preventing the problem that the crushing device cannot roll the oxidized graphene solid on the side, resulting in insufficient rolling of the oxidized graphene solid.

[0012] The beneficial effects of the present invention are as follows: 1. Although the device uses the method of feeding from the outside for feeding, it has a relevant layered structure and can make the main shell body in a relatively sealed closed state by rotating the external rotating sleeve. In this way, the device will not have the problem that the opening is not tightly closed due to the relevant opening, resulting in air leakage of the device.

[0013] 2. During the process of crushing graphene oxide solids, this device uses an automatically adjustable roller rod to press against the outer surface of the graphene oxide solids instead of a rotating shaft rod, avoiding problems such as the rotating shaft rod over-crushing the graphene oxide solids or the distance between the rotating shaft rod and the bottom surface of the main housing being too large, resulting in insufficient crushing of the graphene oxide solids. At the same time, it also avoids the cumbersome detection processes related to debugging the rotating shaft rod.

[0014] 3. Since this device has no relevant external openings, it has strong stability during operation. Moreover, the external rotating machine is not directly connected to the vertical hollow rod. Therefore, even if the outer surface of the output shaft loosens from the inner wall of the connecting sleeve during the rotation of the external rotating machine, there will be no problem of air leakage damaging the vacuum state inside the device.

[0015] 4. During the process of taking materials in a general device, it is usually necessary to open relevant openings, which further leads to poor sealing of the device. When the device opens the opening, the graphene oxide solid powder at the opening will come into contact with a large amount of external air. At this time, the graphene oxide solid powder will deteriorate, which seriously affects the quality of the product. This device rotates the internal plug-in torque rod to connect the through-hole with the through-port groove. The graphene oxide solid powder on the upper surface of the upper fixed plate falls from the through-hole into the sealed container directly below. Since the graphene oxide solid powder is still in a state of isolation from the external gas when the opening of this device is opened, it will not react with the air and deteriorate, and the quality of the product is more guaranteed.

[0016] 5. During the rotation of the rotating chassis, the graphene oxide solid powder will not directly pass through the through-hole and the through-port groove and fall into the container below. It will be discharged to the outside only after another period of grinding process between the upper fixed plate and the rotating chassis. Therefore, the discharging device can play a role in re-grinding the graphene oxide solid powder, preventing problems such as the crushing device being unable to crush the side graphene oxide solids, resulting in insufficient crushing of the graphene oxide solids.

Embodiment

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a graphene oxide vacuum freeze dryer, including a vacuum crusher 1, feeding boxes 2 are symmetrically arranged on the left and right sides of the outer surface of the vacuum crusher 1, support legs 3 are fixedly connected to the lower surface of the feeding boxes 2, a support frame 4 is fixedly connected to the upper surface of the feeding boxes 2, and an external rotating machine 5 is fixedly connected to the middle of the inner wall of the support frame 4.

[0023] The crushing device 7 includes a vertical hollow rod 71. An adapting insertion rod 9 is slidably connected to the inner wall of the vertical hollow rod 71. A tension spring 72 is sleeved on the upper part of the outer surface of the vertical hollow rod 71. A rotating shaft rod 73 is evenly arranged on the lower part of the outer surface of the vertical hollow rod 71. A small elastic frame 76 is evenly arranged on the outer surface of the rotating shaft rod 73. The top end of the small elastic frame 76 is rotatably connected to a grinding rod 77. The top end of the rotating shaft rod 73 is rotatably connected to an auxiliary guide wheel 74. The upper surface of the auxiliary guide wheel 74 is rotatably connected to an interlayer slide plate 75.

[0024] The number of the rotating shaft rods 73 is four. One end of the rotating shaft rod 73 close to the vertical hollow rod 71 is fixedly connected to the lower part of the outer surface of the vertical hollow rod 71. The bottom end of the vertical hollow rod 71 is rotatably connected to the center of the upper surface of the extended bottom shell 15. The outer surface of the auxiliary guide wheel 74 is in rolling connection with the upper surface of the extended bottom shell 15. The upper surface of the interlayer slide plate 75 is slidably connected to the upper part of the inner wall of the main shell 11. The top end of the vertical hollow rod 71 extends to the outside of the main shell 11. The outer surface of the vertical hollow rod 71 is rotatably connected to the center of the upper part of the inner wall of the main shell 11. The outer surface of the vertical hollow rod 71 is fixedly connected to the center of the lower part of the inner wall of the connecting sleeve 13.

[0025] The side surface of the inner rotating cylinder 6 is slidably connected to the lower part of the inner wall of the main shell 11. The bottom end of the external rotating sleeve 62 extends to the outside of the extended bottom shell 15. The outer surface of the external rotating sleeve 62 is slidably connected to the inner wall of the extended bottom shell 15. The bottom of the outer surface of the inclined slide rail 14 is fixedly connected to one side of the inner wall of the main shell 11. The top end of the inclined slide rail 14 extends into the inside of the feeding box 2.

[0026] The top end of the tension spring 72 is fixedly connected to the top end of the vertical hollow rod 71. The bottom end of the tension spring 72 is slidably connected to the center of the upper surface of the main shell 11. The upper part of the inner wall of the connecting sleeve 13 is fixedly connected to the outer surface of the output shaft of the external rotating machine 5.

[0027] Before using the device, first perform the feeding work through the feeding boxes 2 on both sides. The graphene oxide solid particles slide into the inside of the main shell 11 through the inclined slide rail 14. Since the inner rotating cylinder 6 is in the Figure 2 shown state at this time, the adapting through openings 64 on both sides of the rotating ring shell 61 are connected to the bottom end of the inclined slide rail 14. Therefore, the graphene oxide solid particles will enter the inner wall of the rotating ring shell 61, that is, the upper surface of the inclined circular ring 63, through the adapting through openings 64. After the feeding is completed, first rotate the bottom of the external rotating sleeve 62. The graphene oxide solid particles on the upper surface of the inclined circular ring 63 fall into the bottom of the inner wall of the main shell 11 under the action of centrifugal force. The rotating ring shell 61 rotates along the inner wall of the main shell 11. The rotating ring shell 61 rotates Figure 1 ninety degrees clockwise relative to the shown position. The adapting through openings 64 are staggered from the bottom end of the inclined slide rail 14, and the adapting through openings 64 are blocked by the inner wall of the main shell 11, completing the preparation work.

[0028] Before the crushing work is carried out, the air inside the main shell 11 is pumped dry by the air extractors 12 on both sides to keep the inside of the main shell 11 in a relatively vacuum state. Subsequently, the external rotating machine 5 directly above is started, and the vertical hollow rod 71 is controlled to rotate by itself through the connecting sleeve 13. The vertical hollow rod 71 drives the bottom rotating shaft rod 73 to perform circular motion. Because under normal conditions, the grinding rod 77 is squeezed against the upper part of the inner wall of the main shell 11 under the elastic force of the small elastic frame 76, and under the rolling action of the auxiliary guide wheel 74, the rotating shaft rod 73 revolves around the vertical hollow rod 71 as the axis and rotates around its own central axis at the same time. Therefore, the grinding rod 77 on the outer surface of each rotating shaft rod 73 will crush the graphene oxide solid particles directly below.

[0029] After a period of crushing work, the graphene oxide solid particles are broken into smaller powders, achieving the finished product effect. At this time, the bottom of the extended bottom shell 15 is covered with a sealed container, and the bottom of the extended bottom shell 15 is opened. The crushed graphene oxide powder falls into the interior of the container under the action of gravity to obtain the product. Embodiment

[0041] The outer surface of the connecting long rod 91 is slidably connected to the inner wall of the vertical hollow rod 71. The cross-sectional area of the through port 82 is larger than the cross-sectional area of the through slot 84.

[0042] After being rolled, the graphene oxide solid particles will fall out of the inside of the main shell 11 through the through port 82 and the through slot 84. However, in the working state, the upper fixed disk 81 and the rotating chassis 83 have an initial rotation angle. So at this time, the through port 82 and the through slot 84 are staggered with each other, and the whole discharging device 8 cannot be passed through. Therefore, the discharging device 8 can keep the main shell 11 and the extended bottom shell 15 in a relatively sealed state during the working state. After the work is completed, it is necessary to discharge the graphene oxide solid particles. At this time, through the side plug block 92 on the outside of the connecting long rod 91, the connecting long rod 91 is pressed down. The arc-shaped insertion strips 94 on the inner wall of the spherical half-shell sleeve 93 are adaptively clamped with the upper surface of the plugging torque rod 85. Then the side plug block 92 is rotated. The connecting long rod 91 rotates the plugging torque rod 85 through the spherical half-shell sleeve 93. During the rotation of the plugging torque rod 85, the lower rotating chassis 83 is pulled to rotate. During the rotation of the rotating chassis 83, the through slot 84 and the through port 82 will surely be in a state of being connected to each other. At this time, the graphene oxide solid particles can fall into the sealed container directly below through the through slot 84 and the through port 82, completing the collection state.
