Description

Technical Field

[0001] The invention relates to the technical field of chemical experimental equipment, in particular to a storage device based on a chemical microchannel reactor. Background Art

[0002] The establishment of a microreactor technology platform has great potential in the world market. The transformation of channel geometry and structure from microns to millimeters has been carried out in the laboratory, that is, the channel geometry is matched with the subsequent production plant. The productivity, yield, process parameters and product quality determined in the laboratory using this method can be directly transferred to the reactor with the same channel geometry.

[0003] The patent document with publication number CN220949538U discloses a chemical storage tank, including a storage barrel structure, wherein the storage barrel structure includes a liquid storage barrel, the front of which is fixedly connected to a transparent glass plate, the outer wall of which is fixedly connected to a supporting outer ring, the bottom of which is fixedly connected to four supporting legs, the bottom of which is fixedly connected to a drainage pipe, the top of which is fixedly connected to a driving motor, and a sealing plate is provided inside the liquid storage barrel. In the above application document, the liquid guide pipe is connected to the top of the connector pipe, and the connector is pressed. The pipeline causes the connecting head pipeline to drop. The lowering of the connecting head pipeline requires the lock trigger spring. The connecting head pipeline drops and pushes out the inflow platform. The movement of the inflow platform drives the connecting plate to move on the outer wall of the limit rod. The movement of the connecting plate stretches the tension spring, and the raw liquid flows into the device through the groove on the outer wall of the inflow platform. When the raw liquid enters the device, the raw liquid compresses the air inside the device. When the thrust generated by the compressed air can push out the exhaust iron block, the air inside the device is discharged. The overall sealing of the device is poor. During the stirring and mixing of the raw materials and the subsequent storage, gas leakage may occur, which is easy to pollute the environment. Summary of the invention

[0006] According to the above technical solution, the bottom of the insertion part initially contacts the top of the pressure plate, and the return spring is initially in a compressed state. When the top cover is installed to the top of the opening, the insertion part moves downward into the opening to press the pressure plate.

[0007] According to the above technical solution, the sealing airbag is in an expanded state in the initial state, and the end of the sealing airbag away from the inner wall of the opening is tightly fitted with the surface of the insertion part. The expanded state of the sealing airbag is tightly fitted with the surface of the insertion part so that gas cannot pass through, thereby improving the sealing performance.

[0008] According to the above technical scheme, the detachable stirring mechanism includes a stirring shaft, two groups of grooves and a hydraulic warehouse, the bottom of the stirring shaft is rotatably connected to the inner bottom of the chemical microreactor body, the top of the stirring shaft is provided with a slot, the inner bottom of the slot is provided with an elastic spring, and the inner wall of the slot is provided with a slot, the two grooves are respectively provided on both sides of the rotating shaft, the interiors of the two groups of grooves are provided with telescopic springs, the interiors of the two grooves are respectively connected with arc blocks through two groups of telescopic springs, the hydraulic warehouse is fixedly connected to the interior of the rotating shaft, the interior of one end of the hydraulic warehouse is piston-slidingly connected to a pull rod, and the other two ends of the hydraulic warehouse are piston-slidingly connected to connecting rods, the ends of the two groups of connecting rods away from the hydraulic warehouse are respectively fixedly connected to the two groups of arc blocks, the surface of the stirring shaft is fixedly connected with a stirring paddle, the interior of the stirring paddle is provided with an impact assembly, and the end of the stirring paddle away from the stirring shaft is provided with a scraping mechanism.

[0009] According to the above technical solution, the bottom of the rotating shaft is in conflict with the top of the elastic spring in the initial state, and the elastic spring is in a compressed state in the initial state. The rotating shaft moves downward and is inserted into the slot, which squeezes the elastic spring. When the elastic spring rebounds, it drives the rotating shaft to move upward a short distance.

[0010] According to the above technical solution, the size of the slot is equal to that of the groove, and half of the arc block is located inside the slot in the initial state. When the arc block is stuck in the slot, the rotation of the rotating shaft will drive the stirring shaft to rotate synchronously through the cooperation between the arc block and the slot.

[0011] According to the above technical solution, the number of the card slots is set to eight groups, and the eight groups of card slots are arranged in a circular array on the inner wall of the slot. The setting of the eight groups of card slots can ensure the insertion of the arc block.

When the ball moves toward the end away from the stirring shaft, it will hit the expansion airbag, and when the scraper follows the stirring paddle to rotate, it will scrape the inner wall of the chemical microreactor body.

[0015] The present invention provides a storage device based on a microchannel reactor. It has the following beneficial effects:

[0016] (1) The present invention provides a sealing mechanism so that when the top cover is fixed to the top of the opening by bolts, the insertion portion at the bottom of the top cover will press down the pressure plate. At this time, the sealing airbag will expand through the cooperation of the air chamber, piston rod, air pipe and other components. The expanded state of the sealing airbag is closely fitted with the surface of the insertion portion so that gas cannot pass through, thereby improving the sealing performance. After the top cover is removed, the sealing airbag will shrink and return to its original state, and will not be easily affected when the insertion portion is subsequently inserted.

[0017] (2) The present invention provides a detachable stirring mechanism so that when the top cover is fixed to the top of the opening by bolts, the rotating shaft will move downward and insert into the slot at the top of the stirring shaft, and the arc block will automatically snap into the slot on the inner wall of the slot. At this time, when the motor is turned on to drive the rotating shaft to rotate, the stirring shaft will rotate synchronously through the cooperation between the arc block and the slot. When disassembling, the arc block can be pulled out of the slot by pulling the pull rod, and the rotating shaft will move upward a short distance to make the arc block misaligned with the slot. The installation and disassembly are simple and convenient for later maintenance.

[0018] (3) The scraping mechanism of the present invention is set up so that when the motor is turned on, the rotating shaft is driven to rotate. When the rotating shaft rotates, the arc block and the slot cooperate to drive the stirring shaft to rotate synchronously. When the motor drives the rotating shaft to rotate faster, the scraper moves downward through the cooperation of the impact component, the air bag, the air pressure chamber and other components. When the motor drives the rotating shaft to rotate slower, the scraper moves upward to restore. In this way, the stirring effect is improved by driving the rotating shaft to rotate at a variable speed by the motor. At the same time, the scraper rotates and repeatedly moves up and down to clean the inner wall of the chemical microreactor body to prevent the raw materials from adhering.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-4 , one embodiment of the present invention is: a storage device based on a chemical microchannel reactor, comprising a chemical microreactor body 1, a chemical microreactor body 1, a discharge pipe 2 is passed through and fixedly connected to the bottom of the chemical microreactor body 1, an opening 3 is passed through and fixedly connected to the top of the chemical microreactor body 1, a top cover 4 is fixedly installed on the top of the opening 3 by bolts, a protrusion 5 is fixedly connected to the bottom of the top cover 4, a motor 6 is arranged on the top of the top cover 4, a rotating shaft 7 is passed through and rotatably connected to the top of the top cover 4, and the top of the rotating shaft 7 is fixedly connected to the output shaft of the motor 6, and a sealing mechanism 8 and a detachable stirring mechanism 9 are arranged inside the chemical microreactor body 1; the sealing mechanism 8 includes a fixed plate 81 and a sealing airbag 87, the fixed plate 81 is fixedly connected to the inside of the chemical microreactor body 1, the top of the fixed plate 81 is passed through and fixedly connected to the gas chamber 82, and the inside of the gas chamber 82 is provided with a complex The reset spring 83 is in a compressed state in the initial state. When the top cover 4 is installed to the top of the opening 3, the insertion part 5 moves downward into the opening 3 and presses down the pressure plate 85. The side of the air chamber 82 is penetrated and fixedly connected with an air pipe 86. The sealing air bag 87 is fixedly connected to the inner wall of the opening 3. The sealing air bag 87 is in an expanded state in the initial state, and the end of the sealing air bag 87 away from the inner wall of the opening 3 is tightly fitted with the surface of the insertion part 5. The expanded state of the sealing air bag 87 is tightly fitted with the surface of the insertion part 5, so that gas cannot pass through, thereby improving the sealing performance. The end of the air pipe 86 away from the air chamber 82 is penetrated and fixedly connected with the sealing air bag 87.

[0032] When in use, when the top cover 4 is installed, the bottom of the top cover 4 is fitted with the top of the opening 3, and the top cover 4 is fixed to the top of the opening 3 by bolts, and the insertion portion 5 is inserted into the opening 3 downward. At the beginning, the sealing airbag 87 is in a contracted state and will not affect the insertion portion 5 from entering the opening 3. When the insertion portion 5 moves downward and contacts the pressure plate 85, the pressure plate 85 moves downward, and the downward movement of the pressure plate 85 will drive the piston rod 84 to move downward, and the return spring 83 is squeezed and gradually tightened, and the downward movement of the piston rod 84 will squeeze the air in the air chamber 82 so that it enters through the air pipe 86. When the raw materials enter the sealing airbag 87, the sealing airbag 87 will expand. The expanded state of the sealing airbag 87 is closely attached to the surface of the insertion part 5 so that gas cannot pass through, thereby improving the sealing performance, so that the raw materials can be well stored in the chemical microreactor body 1, and no gas will leak out and pollute the environment during the subsequent stirring process. When the top cover 4 is removed to make the insertion part 5 move upward and leave the pressure plate 85, the return spring 83 rebounds and drives the piston rod 84 to move upward and restore. At this time, negative pressure is formed in the air chamber 82 to suck the air from the sealing airbag 87 back into the air chamber 82, and the sealing airbag 87 shrinks and restores.

[0033] See also Figure 1-10On the basis of the above embodiment, in another embodiment of the present invention, the detachable stirring mechanism 9 includes a stirring shaft 91, two groups of grooves 95 and a hydraulic chamber 97. The bottom of the stirring shaft 91 is rotatably connected to the inner bottom of the chemical microreactor body 1. A slot 92 is provided on the top of the stirring shaft 91. An elastic spring 93 is provided on the inner bottom of the slot 92. The bottom of the rotating shaft 7 is in conflict with the top of the elastic spring 93 in the initial state, and the elastic spring 93 is in a compressed state in the initial state. The rotating shaft 7 moves downward and is inserted into the slot 92, which squeezes the elastic spring 93. When the elastic spring 93 rebounds, it drives the rotating shaft 7 to move upward a short distance. A slot 94 is provided on the inner wall of the slot 92. The two grooves 95 are respectively provided at On both sides of the rotating shaft 7, telescopic springs 911 are arranged inside the two groups of grooves 95, and arc blocks 96 are slidably connected inside the two grooves 95 through the two groups of telescopic springs 911. The size of the slot 94 is equal to the size of the slot 95. In the initial state, one-half of the arc block 96 is located inside the slot 94. When the arc block 96 is stuck in the slot 94, the rotation of the rotating shaft 7 will drive the stirring shaft 91 to rotate synchronously through the cooperation of the arc block 96 and the slot 94. The number of the slots 94 is set to eight groups, and the eight groups of slots 94 are arranged in a circular array on the inner wall of the slot 92. The setting of the eight groups of slots 94 can ensure the insertion of the arc block 96. The hydraulic chamber 97 is fixedly connected to the inside of the rotating shaft 7. One end of the hydraulic chamber 97 is inside The piston is slidably connected to a pull rod 98, and the other two ends of the hydraulic chamber 97 are both slidably connected to connecting rods 99. The ends of the two groups of connecting rods 99 away from the hydraulic chamber 97 are fixedly connected to the two groups of arc blocks 96 respectively. A stirring paddle 910 is fixedly connected to the surface of the stirring shaft 91. An impact assembly 10 is arranged inside the stirring paddle 910. The impact assembly 10 includes a cavity 101. The cavity 101 is trapezoidal as a whole. A ball 102 is arranged inside the cavity 101. When the speed of the stirring shaft 91 increases, the centrifugal force generated will throw the ball 102 to the end away from the stirring shaft 91. When the speed of the stirring shaft 91 decreases, the ball 102 will roll back to its original position along the slope of the cavity 101. The stirring paddle 910 is away from the stirring shaft 91. A scraping mechanism 11 is provided at the end, and the scraping mechanism 11 includes an air pressure chamber 111, which passes through and is fixedly connected to the bottom of the stirring paddle 910, and an expansion airbag 112 is provided at one end of the air pressure chamber 111, and a push rod 113 is slidably connected to the internal piston of the other end of the air pressure chamber 111, and a scraper 114 is fixedly connected to the end of the push rod 113 away from the air pressure chamber 111, and the expansion airbag 112 is located at the side end of the cavity 101, and the end of the scraper 114 away from the push rod 113 is in contact with the inner wall of the chemical microreactor body 1, and the ball 102 will hit the expansion airbag 112 when it moves toward the end away from the stirring shaft 91, and the scraper 114 will scrape the inner wall of the chemical microreactor body 1 when it rotates with the stirring paddle 910.

[0034] When in use, when installing the top cover 4, the shaft 7 will move downward and be inserted into the slot 92 at the top of the stirring shaft 91, and the elastic spring 93 will be squeezed and gradually tightened. At the beginning, the curved surface of the arc block 96 will be squeezed with the top of the slot 92, and the curved surface of the arc block 96 will be squeezed and shrink into the groove 95, and the telescopic spring 911 will be tightened. When the groove 95 fits with the card slot 94, the telescopic spring 911 rebounds and drives the arc block 96 to be stuck in the slot 92. The arc block 96 is stuck in the card slot 94, so that the shaft 7 cannot move upward to leave the slot 92. At this time, when the motor 6 is turned on to drive the shaft 7 to rotate, it will pass through the arc block The cooperation between 96 and the card slot 94 drives the stirring shaft 91 to rotate synchronously. When disassembling, the pull rod 98 is pulled sideways. The pull rod 98 moves toward the outside of the hydraulic chamber 97 and drives the other two end connecting rods 99 to move toward the inside of the hydraulic chamber 97 through the hydraulic pressure, thereby driving the two groups of arc blocks 96 to leave the card slot 94 at the same time. When the two groups of arc blocks 96 leave the card slot 94 at the same time, the elastic spring 93 will rebound and drive the shaft 7 to move upward for a short distance so that the groove 95 is misaligned with the card slot 94, and then the shaft 7 can be made to leave the slot 92. The installation and disassembly are simple and convenient for later maintenance, and the internal structure of the chemical microreactor body 1 needs to be adjusted. When the raw materials are stirred, the motor 6 can be turned on to drive the rotating shaft 7 to rotate at a variable speed. The rotating shaft 7 rotates at a variable speed to drive the stirring shaft 91 to rotate at a variable speed. The stirring shaft 91 rotates at a variable speed to drive the stirring paddle 910 to rotate at a variable speed to stir the raw materials inside the chemical microreactor body 1. The stirring effect is better by continuously stirring at a variable speed. At the same time, the scraper 114 scrapes the inner wall of the chemical microreactor body 1 when following the rotation of the stirring paddle 910. The centrifugal force generated when the speed of the stirring shaft 91 increases will throw the ball 102 to the end away from the stirring shaft 91. When the ball 102 moves to the end away from the stirring shaft 91, it will collide with the expanded gas. The air bag 112 is expanded, and the air pressure inside it enters the air pressure chamber 111 to push the push rod 113 to move downward. The downward movement of the push rod 113 will drive the scraper 114 to move downward. When the rotation speed of the stirring shaft 91 slows down, the ball 102 will roll back to its original position along the slope of the cavity 101. At this time, the rebound air pressure of the expanded air bag 112 returns to the expanded air bag 112, and the push rod 113 moves upward to drive the scraper 114 to move upward and restore. When the stirring shaft 91 changes speed, the scraper 114 will also move up and down repeatedly, thereby fully scraping the inner wall of the chemical microreactor body 1 to prevent the raw materials from adhering.
