Description

Technical Field

[0001] The invention belongs to the technical field of sublimation, and in particular relates to a furnace type solid phase separation sublimation device. Background Art

[0002] Furnace solid phase separation sublimation is a separation technology that is usually used to separate a single substance from a solid mixture. In this method, by heating the solid mixture, one of the substances sublimates and converts to gas between solid phases, and then by controlling the temperature and pressure, the sublimated substance is transferred to another collection device to achieve separation. The principle of this method is based on the fact that different substances have different sublimation points. In a mixture, when appropriate temperature and pressure are applied, one of the substances may sublime before the other substances. By controlling the temperature and pressure, the desired substance can be sublimated while keeping the other substances in the solid phase. Then, the sublimated substance is transferred to another location through the gas phase for collection or treatment. Furnace solid phase separation sublimation is usually used to separate pure compounds or extract substances with higher purity, such as extracting drugs from natural products or extracting pure products from chemical reaction products.

[0003] During the sublimation process, toxic gases may be produced, so the raw materials are usually sealed. However, toxic gases may still escape through the gaps between the equipment interfaces or other parts, affecting the safety of operators. Therefore, it is best to place all the sublimation equipment in a confined space. However, for some equipment that requires open flame heating, combustion may not continue, affecting the normal sublimation.

[0004] As can be seen from the above, the existing furnace-type solid phase separation sublimation device cannot seal the equipment while ensuring combustion, and has poor safety. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0018] See also Figure 1-Figure 5 , an embodiment of the present invention provides a furnace-type solid-phase separation and sublimation device, the furnace-type solid-phase separation and sublimation device comprising: A sublimation box 1; and an air inlet and outlet assembly 2 installed on the top of the sublimation box 1, used for air inlet and outlet inside the sublimation box 1; The air inlet and outlet assembly 2 comprises: A driving member installed on the top of the sublimation box 1 through a motor frame 201; and a rotating shaft 203 fixedly connected to the output end of the driving member; The rotating shaft 203 is fixedly connected with an incomplete gear 204; An air intake gear 205 is meshed on one side of the incomplete gear 204; and a winding roller 206 is coaxially connected to the air intake gear 205; The winding roller 206 is connected to a first weight rack 208 via a first pull rope 207, and the first weight rack 208 is slidably connected to the side wall of the sublimation box 1; The first weight rack 208 is disposed on the top of the supply air bag 209, and the bottom of the supply air bag 209 is connected to the sublimation box 1 through the first one-way valve 2010; An outlet gear 2011 is meshed on the side of the incomplete gear 204 away from the air inlet gear 205, and a discharge roller 2012 is coaxially connected to the outlet gear 2011. The discharge roller 2012 is connected to a second weight rack 2014 via a second pull rope 2013. The second weight rack 2014 is arranged on the top of a collecting air bag 2015, and the collecting air bag 2015 is connected to the sublimation box 1 via a second one-way valve 2016. A sealing door 2017 is provided on one side of the sublimation box 1 .

[0019] In the embodiment of the present invention, the size and shape of the sublimation box 1 are not limited. The size of the sublimation box 1 should be determined according to the size of the air inlet and outlet components 2 on one side thereof. The shape of the sublimation box 1 is also not limited, and it can be cabinet-shaped, box-shaped, or other required shapes.

[0020] In this embodiment, the sublimation box 1 is mainly used for sublimation operation. It is a sealed structure. The sublimation box 1 can only be inlet and outlet through the first one-way valve 2010 and the second one-way valve 2016. A motor frame 201 is installed on the top of the sublimation box 1. The driving member is installed on the motor frame 201, wherein the driving member is a servo motor 202, and can also be a stepping motor. In this embodiment, the driving member is a servo motor 202, and the rotating shaft 203 is fixedly connected to the output end of the servo motor 202. The incomplete gear During the rotation, the wheel 204 will mesh with the air inlet gear 205 and the air outlet gear 2011 respectively. The supply airbag 209 and the collection airbag 2015 are elastic airbags, similar to balloons, but the supply airbag 209 and the collection airbag 2015 will restore their deformation when not squeezed; the tops of the supply airbag 209 and the collection airbag 2015 are provided with interfaces and are equipped with one-way valves. When the top interface of the supply airbag 209 is opened, the supply airbag 209 will inhale fresh air from the outside when not squeezed.

[0021] In actual use, the combustion equipment, collection equipment, etc. used for sublimation operation are placed inside the sublimation box 1, the sealing door 2017 is closed, and the servo motor 202 is started, which will cause the rotating shaft 203 to rotate and drive the incomplete gear 204 to rotate. When the incomplete gear 204 is meshed with the intake gear 205, it will drive the winding roller 206 to rotate and reel in the first pull rope 207. At this time, the first weight rack 208 moves upward, the supply air bag 209 loses pressure, restores deformation, and inhales fresh air from the outside. When the incomplete gear 204 continues to rotate and disengages from the intake gear 205, the first weight rack 208 loses tension and moves downward, squeezing the supply air bag 209, and the air in the supply air bag 209 is filled with air. Fresh air is pressed into the sublimation box 1 through the first one-way valve 2010 to participate in the combustion. At this time, the servo motor 202 is paused. After burning for a period of time, the servo motor 202 is started again, and the incomplete gear 204 gradually engages with the air outlet gear 2011. At this time, the air outlet gear 2011 drives the second weight rack 2014 to move upward through the second pull rope 2013, and makes the collecting air bag 2015 lose its extrusion. At this time, the collecting air bag 2015 inhales the toxic gas inside the sublimation box 1 through the second one-way valve 2016. When the servo motor 202 continues to rotate and gradually disengages from the air outlet gear 2011, the second weight rack 2014 loses its pulling force, moves downward, and squeezes the collecting air bag 2015.

[0022] It can be seen from this that the air flow direction of the one-way valve at the interface of the supply airbag 209 is from the outside to the supply airbag 209, the air flow direction at the first one-way valve 2010 is from the supply airbag 209 to the sublimation box 1, the air flow direction at the second one-way valve 2016 is from the sublimation box 1 to the collecting airbag 2015, and the air flow direction of the one-way valve at the top interface of the collecting airbag 2015 is to escape from the collecting airbag 2015 to other locations. The air can flow normally along the above directions, otherwise it cannot pass through.

[0023] In one embodiment of the present invention, see Figure 3 The first pull rope 207 and the second pull rope 2013 are wound with steering rollers 2018, and the two groups of steering rollers 2018 are symmetrically installed on both sides of the top of the sublimation box 1.

[0024] In this embodiment, by setting two sets of steering rollers 2018, the pulling direction of the first pull rope 207 and the second pull rope 2013 can be adjusted, so that the first weight rack 208 and the second weight rack 2014 can move in the vertical direction, thereby controlling the air inlet and outlet of the supply airbag 209 and the collection airbag 2015.

[0025] In one embodiment of the present invention, see Figure 4 The top of the first weight rack 208 is connected to the outer cover 2020 through a first elastic member, and the outer cover 2020 is fixedly connected to the side wall of the sublimation box 1.

[0026] In this embodiment, two groups of first elastic members are installed on the top of the first weight rack 208, wherein the first elastic member is a return spring 2019, which can also be a rubber column. In this embodiment, the first elastic member is a return spring 2019, one end of the return spring 2019 is connected to the first weight rack 208, and the other end is connected to the top inner wall of the outer cover 2020. When the incomplete gear 204 engages with the intake gear 205 and pulls the first weight rack 208 upward, the return spring 2019 will contract. When the incomplete gear 204 no longer engages with the intake gear 205, the first weight rack 208 will move downward under the action of its own gravity and the gravity of the return spring 2019.

[0027] In one embodiment of the present invention, see Figure 5 The top of the collecting air bag 2015 is connected to a gas collecting box 2022 through a hose 2021, and the gas collecting box 2022 is fixedly connected to the top of the sublimation box 1.

[0028] In an embodiment of the present invention, one end of the hose 2021 is connected to the top interface of the collecting air bag 2015, and the other end is connected to the gas collecting box 2022. Through the setting of the gas collecting box 2022, the toxic gas in the collecting air bag 2015 can be collected, effectively avoiding the escape of toxic gas and ensuring the safety of the operator. The gas collecting box 2022 can be connected to a toxic gas processing device or a collecting device to achieve the processing and recovery of the toxic gas.

[0029] In one embodiment of the present invention, see Figure 1 , the furnace-type solid phase separation sublimation device also includes: The collecting assembly 3 is connected to the air collecting box 2022 and is used to assist the air collecting box 2022 in taking in and exhausting air.

[0030] In this embodiment, by setting up the collecting component 3, the toxic gas can be recovered, thereby further improving the safety of the device.

[0031] In one embodiment of the present invention, see Figure 5 and Figure 6 , the collecting component 3 comprises: A cam 301 is fixedly connected to one end of the rotating shaft 203 away from the driving member; and a toothed plate frame 302 abutting against the cam 301, and the toothed plate frame 302 is slidably connected to the top of the sublimation box 1; A driven gear 303 meshing with the toothed plate frame 302; and a screw rod 304 coaxially connected to the driven gear 303, wherein one end of the screw rod 304 away from the driven gear 303 is rotatably connected to the air collecting box 2022; The screw rod 304 is located inside the air collecting box 2022 and is connected to a piston plate 305 through threads. The piston plate 305 is fitted inside the air collecting box 2022 .

[0032] In this embodiment, a cam 301 is fixedly connected to one end of the rotating shaft 203 away from the servo motor 202 , and a toothed plate frame 302 is provided on the envelope surface of the cam 301 , wherein the toothed plate frame 302 is divided into a vertical abutting portion and a horizontal toothed plate portion.

[0033] In actual use, the rotating shaft 203 will be squeezed with the abutting part of the gear plate frame 302 during the rotation process, causing the gear plate frame 302 to move and engage to drive the driven gear 303 to rotate, while causing the screw 304 to rotate, thereby causing the piston plate 305 inside the air collecting box 2022 to move inside the air collecting box 2022.

[0034] It should be noted that during the above-mentioned movement process, suction will be generated inside the gas collecting box 2022. At this time, the second heavy object rack 2014 happens to move downward, squeezing the collecting air bag 2015, thereby better sucking the toxic gas inside the collecting air bag 2015 into the gas collecting box 2022.

[0035] In one embodiment of the present invention, see Figure 5 One side of the tooth plate frame 302 is connected to a support plate 307 through a second elastic member, and the support plate 307 is fixedly connected to the top of the sublimation box 1.

[0036] In this embodiment, the abutting portion of the tooth plate frame 302 is connected to the support plate 307 via a second elastic member, wherein the second elastic member is a connecting spring 306, which can also be a rubber column. In this embodiment, it is a connecting spring 306, one end of the connecting spring 306 is connected to the tooth plate frame 302, and the other end is connected to the support plate 307. By setting the connecting spring 306, the tooth plate frame 302 can always keep in contact with the cam 301, so that the position of the tooth plate frame 302 can be adjusted by rotating the cam 301.

[0037] In actual use, the combustion equipment, collection equipment, etc. used for sublimation operation are placed inside the sublimation box 1, and the sealing door 2017 is closed; starting the servo motor 202 will cause the rotating shaft 203 to rotate and drive the incomplete gear 204 to rotate. When the incomplete gear 204 is meshed with the intake gear 205, it will drive the winding roller 206 to rotate and reel in the first pull rope 207. At this time, the first weight rack 208 moves upward, the supply air bag 209 loses pressure, restores deformation, and inhales fresh air from the outside. When the incomplete gear 204 continues to rotate and disengages from the intake gear 205, the first weight rack 208 loses tension and moves downward, squeezing the supply air bag 209, and the fresh air in the supply air bag 209 is compressed through the first one-way valve 2010. 2015, and the servo motor 202 is turned on again, and the incomplete gear 204 gradually meshes with the air outlet gear 2011. At this time, the air outlet gear 2011 drives the second weight rack 2014 to move upward through the second pull rope 2013, and makes the collecting air bag 2015 lose its squeezing. At this time, the collecting air bag 2015 inhales the toxic gas inside the sublimation box 1 through the second one-way valve 2016. When the servo motor 202 continues to rotate and gradually disengages from the air outlet gear 2011, the second weight rack 2014 loses its pulling force, moves downward, squeezes the collecting air bag 2015, and presses the toxic gas in the collecting air bag 2015 into the collecting box 2022 through the hose 2021.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
