Description

Technical Field

[0001] This invention relates to the field of cytosine production technology, specifically a high-pressure stirred tank for cytosine production. Background Technology

[0002] Cytosine is an important intermediate in fine chemicals, pesticides, and pharmaceuticals. It can be used in the synthesis of nucleoside peptide pesticides and antibiotics, anti-AIDS drugs, drugs for treating chronic hepatitis B, and anti-tumor drugs. In the production process of cytosine, the raw materials need to be mixed and stirred in a high-pressure mixing tank to ensure uniform mixing, accelerate the reaction rate, and improve production efficiency.

[0003] Patent application number 2021113758366 discloses a novel fluorocytosine stirring method and stirring device, including a tank, cover plate, motor, turntable, rotating shaft and two sets of stirring units, etc. The stirring effect of this device is still poor and the stirring efficiency is low.

[0004] Patent application number 2019218140739 discloses a fermentation device for cytosine production, including a fermentation storage tank. A pump body is embedded in one side of the fermentation storage tank, and a fermentation vessel is provided on the upper surface of the fermentation storage tank. However, when the pressure inside the fermentation vessel is too low, it is inconvenient to pressurize the inside of the fermentation vessel in a timely manner, and it is inconvenient to adjust the pressure inside the fermentation vessel in a timely manner according to production needs.

[0005] Furthermore, in existing high-pressure mixing tanks, the seals at the top inlet and bottom outlet are prone to corrosion and aging after prolonged use, affecting the tank's sealing performance, which is difficult to detect in time during use. In addition, during the feeding process, raw materials tend to accumulate and clump after entering the tank, which is not conducive to uniform mixing of raw materials. Moreover, blockages are prone to occur during discharge, and a large amount of material tends to adhere to the inner wall of the tank, making it inconvenient to clean the inner wall of the tank. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the existing defects and provide a high-pressure mixing tank for cytosine production. While achieving full and uniform mixing between raw materials, the sealing performance of the tank can be tested before use, and the pressure inside the tank can be easily adjusted. In addition, it can effectively prevent raw materials from accumulating and clumping when adding materials into the tank, and can clean the material adhering to the inner wall of the tank. It can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-pressure stirring tank for cytosine production, comprising a tank body, a power assembly at the top of the tank body, the power assembly comprising a rotating column rotatably connected to the middle of the top surface of the tank body, a second electric push rod at the bottom end of the rotating column, a square seat at the bottom end of the second electric push rod, an installation groove in the middle of the square seat, and fixed shafts symmetrically penetrating both sides of the installation groove;

[0008] The power assembly is equipped with a stirring assembly, which includes two fixed arc-shaped plates. The two fixed arc-shaped plates are symmetrically arranged on the fixed shafts on both sides at opposite ends. A movable arc-shaped plate is movably connected to one side of each fixed arc-shaped plate. An arc-shaped extension plate is slidably connected to the surface of each fixed arc-shaped plate. There are two arc-shaped extension plates. The opposite sides of the two arc-shaped extension plates located on the same fixed arc-shaped plate are connected by a permanent magnet block. An electromagnet corresponding to the permanent magnet block is provided on the surface of the fixed arc-shaped plate.

[0009] A controller is provided on the outside of the tank, and the output end of the controller is electrically connected to the input end of the second electric push rod and the electromagnet, respectively.

[0010] Preferably, a filling cylinder is provided on one side of the top of the tank, and a sealing cap is correspondingly fitted inside the filling cylinder. A support is provided on the top surface of the tank, and a first electric push rod is provided on the top inner side of the support. The bottom end of the first electric push rod is fixedly connected to the top surface of the sealing cap. A sealing gasket is fitted on the sealing cap, and a first air pressure sensor is provided on the bottom surface of the sealing cap. The input ends of the first air pressure sensor and the first electric push rod are electrically connected to the output end of the controller, respectively. The extension and retraction of the first electric push rod drives the sealing cap to rise and fall, thereby realizing the opening and closing of the filling cylinder. The first air pressure sensor at the bottom of the sealing cap can be used to detect the pressure value inside the tank and at the same time to detect the sealing performance at the filling cylinder.

[0011] Preferably, a discharge pipe is provided on the bottom side of the tank, and a rotary motor is provided on the circumferential surface of the discharge pipe. A sealing disc is correspondingly fitted inside the discharge pipe. The circumferential side of the sealing disc is fixedly connected to the output shaft of the rotary motor. A hydraulic sensor is embedded in the side of the sealing disc. The input ends of the rotary motor and the hydraulic sensor are electrically connected to the output end of the controller, respectively. The rotary motor can drive the sealing disc to rotate, thereby realizing the opening and closing of the discharge pipe. The hydraulic sensor is used to detect the pressure value inside the tank and to detect the sealing performance at the discharge pipe.

[0012] Preferably, the top of the tank is equipped with a stirring motor, the output shaft of the stirring motor is fixedly connected to the top of the rotating column, the middle of the side of the fixed arc plate is fixedly connected to the end of the fixed shaft, the input end of the stirring motor is electrically connected to the output end of the controller, the stirring motor drives the rotating column to rotate, and then drives the second electric push rod to rotate, thereby realizing the mixing and stirring of the raw materials in the tank.

[0013] Preferably, each of the two fixed shafts on both sides is provided with a secondary bevel gear at one end, an adjustment motor is provided at the top of the mounting groove, the output shaft of the adjustment motor is provided with a main bevel gear, the main bevel gear meshes with the secondary bevel gears on both sides, the input end of the adjustment motor is electrically connected to the output end of the controller, the adjustment motor drives the main bevel gear to rotate, and the main bevel gear meshes with the secondary bevel gears on both sides to drive the synchronous reverse rotation of the fixed arc plates on both sides.

[0014] Preferably, the arc-shaped extension plates are symmetrically distributed on both sides of the surface of the fixed arc-shaped plate. The distance between the opposite ends of the two arc-shaped extension plates is equal to the width of the side of the square seat near the fixed arc-shaped plate. The extension plates on both sides can be merged when they are in a horizontal state, and the arc-shaped plate is driven to move through the connecting rod and the connecting seat.

[0015] Preferably, the movable arc plate has a connecting seat on the side near the fixed arc plate, and a pin is rotatably connected to the end of the connecting seat away from the fixed arc plate. A connecting rod is provided on the side of the pin, and the other end of the connecting rod is hinged to the side of the arc extension plate. A torsion spring is sleeved on the outer end of the pin. One end of the torsion spring is fixedly connected to the side of the connecting seat, and the other end of the torsion spring is fixedly connected to the pin. When the extension plate slides, the pin can be rotated by the connecting rod, which in turn rotates the torsion spring. The swing of the movable arc plate is achieved by the cooperation of the electromagnet and the permanent magnet block.

[0016] Preferably, in the horizontal state, the outer circumferences of the fixed arc plate and the moving arc plate on both sides are concentric, and the arc extension plates on both sides close just after being unfolded in the horizontal state. Furthermore, the outer circumferences of the arc extension plates are concentric with the outer circumferences of the fixed arc plate. The outer circumferences of the fixed arc plate, the moving arc plate, and the unfolded arc extension plates are concentric in the horizontal state, so that the fixed arc plate, the moving arc plate, and the unfolded arc extension plates can be combined into a disk in the horizontal state.

[0017] Preferably, when the center of the fixed arc plate and the moving arc plate coincides with the center of the arc extension plate, the outer arc surfaces of the fixed arc plate, the moving arc plate and the arc extension plate are in contact with the inner wall of the tank. The outer arc surfaces of the fixed arc plate, the moving arc plate and the unfolded arc extension plate in the horizontal state are in contact with the inner wall of the tank to achieve sealing of the inside of the tank.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] Before use, this invention can combine an arc-shaped extension plate, a fixed arc-shaped plate, and a moving arc-shaped plate into a disc, and then use the rising and falling of the disc to check the sealing of the injection cylinder at the top of the tank and the discharge pipe at the bottom of the tank respectively. If a sealing problem is found, it can be promptly reminded and maintained to avoid affecting the production of cytosine during use.

[0020] This invention allows for the mixing of materials into a tank by keeping both the fixed arc plate and the moving arc plate vertical and perpendicular to each other. The rotation of the fixed arc plate disperses the incoming material, ensuring that the raw materials are evenly distributed within the tank and preventing them from clumping together.

[0021] This invention enables the mixing of raw materials during the stirring process by having the fixed and moving arc plates on both sides intersect each other and by rotating the square base. At the same time, the reciprocating oscillation of the fixed and moving arc plates further makes the mixing of raw materials more uniform and thorough.

[0022] After mixing is completed, the present invention can adaptively adjust the pressure inside the tank by raising and lowering a disc composed of an arc-shaped extension plate, a fixed arc-shaped plate, and a moving arc-shaped plate, so as to make the pressure inside the tank more compatible with the reaction between the raw materials, thereby improving the reaction effect between the raw materials.

[0023] During material discharge, the present invention can push the material at the bottom of the tank out of the discharge pipe by moving the disc composed of the arc-shaped extension plate, the fixed arc-shaped plate and the moving arc-shaped plate downward. This can effectively prevent material blockage at the discharge pipe and speed up the discharge of material. At the same time, the outer circumference of the disc fits against the inner wall of the tank and can scrape off the material adhering to the inner wall of the tank, thus cleaning the inner wall of the tank.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First Embodiment

[0035] Please see Figure 1 , 3 In embodiment 7, this embodiment provides a technical solution: a high-pressure stirring tank for cytosine production, comprising a tank body 1, a power assembly 2 at the top of the tank body 1, the power assembly 2 including a rotating column 202 rotatably connected to the middle of the top surface of the tank body 1, a second electric push rod 203 at the bottom end of the rotating column 202, a square seat 204 at the bottom end of the second electric push rod 203, an installation groove 205 in the middle of the square seat 204, and fixed shafts 206 symmetrically passing through both sides of the installation groove 205. Specifically, the extension and retraction of the second electric push rod 203 drives the square seat 204 to rise and fall, thereby stirring and mixing liquids at different heights in the tank body 1, improving the stirring effect.

[0036] A stirring motor 201 is installed on the top of the tank 1. The output shaft of the stirring motor 201 is fixedly connected to the top of the rotating column 202. The middle of the side of the fixed arc plate 301 is fixedly connected to the end of the fixed shaft 206. The input end of the stirring motor 201 is electrically connected to the output end of the controller. Specifically, the rotation of the stirring motor 201 drives the rotating column 202 to rotate, which in turn drives the square seat 204 to rotate through the second electric push rod 203, thereby realizing the stirring of the raw materials in the tank 1.

[0037] The power assembly 2 is equipped with a stirring assembly 3, which includes a fixed arc plate 301. There are two fixed arc plates 301, which are symmetrically arranged on the fixed shafts 206 on both sides at opposite ends. A movable arc plate 302 is movably connected to one side of the fixed arc plate 301. At this time, the movable arc plate 302 is perpendicularly connected to the fixed arc plate 301, and the movable arc plates 302 on both sides are arranged crosswise. This state is the initial state of the movable arc plate 302 and the fixed arc plate 301.

[0038] A controller is provided on the outside of the tank body 1. The output end of the controller is electrically connected to the input end of the second electric push rod 203. The controller is used to analyze and process the data information of each electrical component, and at the same time realize the electrical control of each electrical component.

[0039] A filling cylinder 101 is provided on one side of the top of the tank body 1. A sealing cover 102 is correspondingly fitted inside the filling cylinder 101. A sealing gasket is fitted on the sealing cover 102. Specifically, the sealing cover 102 can seal the filling cylinder 101, and the sealing gasket can increase the sealing effect.

[0040] A discharge pipe 104 is provided on the bottom side of the tank body 1. A rotary motor 105 is provided on the circumferential surface of the discharge pipe 104. A sealing disc 106 is correspondingly fitted inside the discharge pipe 104. The circumferential side of the sealing disc 106 is fixedly connected to the output shaft of the rotary motor 105. The input end of the rotary motor 105 is electrically connected to the output end of the controller. The rotation of the rotary motor 105 can drive the sealing disc 106 to rotate, thereby realizing the opening and closing of the discharge pipe 104.

[0041] In this embodiment, after the raw material is injected into the tank 1, the sealing cover 102 is fitted with the injection cylinder 101 to seal the injection cylinder 101. The stirring motor 201 is started to drive the rotating column 202 to rotate, and then the second electric push rod 203 drives the square seat 204 to rotate, thereby realizing the rotation of the fixed arc plate 301 and the moving arc plate 302 that intersect on both sides, which can stir the raw material in the tank 1. At the same time, the extension and retraction of the second electric push rod 203 can drive the square seat 204 to rise and fall, thereby mixing the raw material at different heights. After use, the rotary motor 105 drives the sealing plate 106 to rotate, thereby opening the discharge pipe 104 and discharging the raw material in the tank 1.

[0042] Second Embodiment

[0043] Please see Figure 1-8 Based on the high-pressure stirred tank for cytosine production provided in the first embodiment, during long-term use, the sealing cap 102 and sealing disc 106 are prone to corrosion and aging, affecting the sealing effect of the tank 1. Furthermore, it is difficult to detect and maintain this in a timely manner, thus affecting cytosine production. After mixing, it is inconvenient to adjust the pressure inside the tank 1 according to pressure changes, thereby affecting the reaction effect between raw materials inside the tank 1. In addition, during the feeding process, the raw materials accumulate and clump inside the tank, making it difficult to evenly disperse them within the tank 1, and resulting in poor mixing and incomplete uniform mixing of the raw materials. To solve the above problems:

[0044] Each of the two fixed shafts 206 has a secondary bevel gear 207 at one end opposite to the other. An adjustment motor 208 is provided at the top of the mounting groove 205. The output shaft of the adjustment motor 208 has a main bevel gear 209. The main bevel gear 209 meshes with the secondary bevel gears 207 on both sides. The input end of the adjustment motor 208 is electrically connected to the output end of the controller. Specifically, the rotation of the adjustment motor 208 can drive the main bevel gear 209 to rotate. The main bevel gear 209 can achieve synchronous reverse rotation of the two fixed shafts 206 by meshing with the secondary bevel gears 207 on both sides.

[0045] An arc-shaped extension plate 303 is slidably connected to the surface of the fixed arc plate 301. There are two arc-shaped extension plates 303. The opposite sides of the two arc-shaped extension plates 303 located on the same fixed arc plate 301 are connected by a permanent magnet block 304. An electromagnet 305 corresponding to the permanent magnet block 304 is provided on the surface of the fixed arc plate 301. The output end of the controller is electrically connected to the input end of the electromagnet 305. Specifically, by making the magnetic poles between the electromagnet 305 and the permanent magnet block 304 the same, the magnetic repulsion between the electromagnet 305 and the permanent magnet block 304 can be used to drive the arc-shaped extension plate 303 to slide, thereby adjusting the angle of the movable arc plate 302.

[0046] The arc-shaped extension plates 303 are symmetrically distributed on both sides of the surface of the fixed arc plate 301. The distance between the opposite ends of the two arc-shaped extension plates 303 is equal to the width of the side of the square base 204 near the fixed arc plate 301. Specifically, when both arc-shaped extension plates 303 are in a horizontal position, the distance between the two arc-shaped extension plates 303 on the same side is exactly equal to the width of the square base 204. At this time, the magnetic repulsion between the electromagnets 305 and the permanent magnet blocks 304 on both sides can be used to drive the arc-shaped extension plates 303 on both sides to slide in opposite directions, thereby achieving the closure of the arc-shaped extension plates 303 on both sides. At this time, the gap between the opposite ends of the two arc-shaped extension plates 303 on the same side is exactly matched with the width of the square base 204, and the side of the permanent magnet block 304 is in contact with the side of the square base 204.

[0047] A connecting seat 306 is provided on the side of the movable arc plate 302 near the fixed arc plate 301. A pin 307 is rotatably connected to the end of the connecting seat 306 away from the fixed arc plate 301. A connecting rod 308 is provided on the side of the pin 307. The other end of the connecting rod 308 is hinged to the side of the arc extension plate 303. A torsion spring 309 is sleeved on the outer end of the pin 307. One end of the torsion spring 309 is fixedly connected to the side of the connecting seat 306, and the other end of the torsion spring 309 is fixedly connected to the pin 307. Specifically, when the arc extension plate 303 is driven to slide by the magnetic repulsion between the electromagnet 305 and the permanent magnet block 304, the movable arc plate 302 is rotated by the connecting rod 308 and the connecting seat 306, thereby adjusting the angle of the movable arc plate 302 under the action of the torsion spring 309.

[0048] In a horizontal state, the outer circumferences of the fixed arc plate 301 and the movable arc plate 302 on both sides are concentric. When the two arc extension plates 303 are unfolded in a horizontal state, they just close. The outer circumference of the arc extension plate 303 is concentric with the outer circumference of the fixed arc plate 301. When the center of the fixed arc plate 301 and the movable arc plate 302 coincides with the center of the arc extension plate 303, the outer arc surfaces of the fixed arc plate 301, the movable arc plate 302 and the arc extension plate 303 are in contact with the inner wall of the tank body 1. Specifically, when the two arc extension plates 303, the fixed arc plate 301 and the movable arc plate 302 on both sides are in a horizontal state and the two arc extension plates 303 on both sides are closed, the outer circumferences of the two arc extension plates 303, the fixed arc plate 301 and the movable arc plate 302 on both sides are in contact with the inner wall of the tank body 1, thereby dividing the tank body 1 into upper and lower sealed areas.

[0049] The top surface of the tank 1 is provided with a support 108, and the top inner side of the support 108 is provided with a first electric push rod 109. The bottom end of the first electric push rod 109 is fixedly connected to the top surface of the sealing cover 102. The bottom surface of the sealing cover 102 is provided with a first air pressure sensor 103. The input ends of the first air pressure sensor 103 and the first electric push rod 109 are electrically connected to the output end of the controller, respectively. Specifically, the extension and retraction of the first electric push rod 109 can drive the sealing cover 102 to rise and fall, thereby realizing the electric lifting and lowering of the sealing cover 102 and facilitating the control of the opening and closing of the filling cylinder 101.

[0050] A hydraulic sensor 107 is embedded in the side of the sealing disc 106. The input end of the hydraulic sensor 107 is electrically connected to the output end of the controller. Specifically, the hydraulic sensor 107 can be used to detect the pressure of the liquid inside the tank 1 in order to determine the internal pressure of the tank 1.

[0051] In this embodiment, before adding raw materials to the inner wall of the tank 1, the sealing performance of the tank 1 is tested. If the filling cylinder 101 is properly sealed, the discharge pipe 104 is opened. The adjusting motor 208 drives the main bevel gear 209 to rotate. The main bevel gear 209 meshes with the secondary bevel gears 207 on both sides, causing the fixed arc plates 301 on both sides to rotate synchronously in opposite directions until the fixed arc plates 301 on both sides are in a horizontal state. At this point, the distance between the opposite ends of the two arc-shaped extension plates 303 corresponds exactly to the width of the square base 204. Then, the electromagnet 305 is activated, and... The electromagnet 305 and the permanent magnet block 304 are made to have the same magnetic poles, thereby using magnetic repulsion to drive the permanent magnet blocks 304 on both sides to slide the arc-shaped extension plates 303 on both sides in opposite directions, so that the arc-shaped extension plates 303 on both sides are completely closed. During this process, the sliding of the arc-shaped extension plates 303 drives the moving arc-shaped plate 302 to rotate through the connecting rod 308 and the connecting seat 306. When the arc-shaped extension plates 303 on both sides are completely closed, the moving arc-shaped plates 302 on both sides are just in a horizontal state. At this time, the arc-shaped extension plates 303, the fixed arc-shaped plate 301 and the moving arc-shaped plate 302 are combined to form a disk, such as Figure 5As shown, the outer circumferential surfaces of the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 are attached to the middle of the inner wall of the tank 1, dividing the tank 1 into upper and lower chambers. Next, the rotary motor 105 drives the sealing disc 106 to rotate, and then the second electric push rod 203 retracts by a distance of "a", thereby causing the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 to move upwards. The air pressure in the chamber above the fixed arc-shaped plate 301 in the tank 1 increases. The first air pressure value measured by the air pressure sensor 103 when the second electric push rod 203 retracts by a distance of "a" is recorded. After a period of use, before using it again, the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 are first retracted. 02 are combined into a disc, and the combined disc is located in the middle of the tank 1, while the discharge pipe 104 is still open and the injection cylinder 101 is in a sealed state. At this time, the second electric push rod 203 is retracted again, and the retraction distance is also "a". The second air pressure value measured by the air pressure sensor 103 is recorded at this time, and the difference between the measured first air pressure value and the second air pressure value is calculated. When the difference between the first air pressure value and the second air pressure value is greater than the first threshold set by the controller, it is actively determined that there is a leakage at the position of the sealing cover 102 on the top injection cylinder 101, that is, there is a problem with the seal at the sealing cover 102. Thus, the controller can promptly remind the staff to perform timely maintenance to prevent the production of cytosine from being affected during use.

[0052] Secondly, assuming the seal at the discharge pipe 104 is intact, the first electric push rod 109 drives the sealing cover 102 upward, causing the sealing cover 102 to detach from the injection cylinder 101, thus opening the injection cylinder 101. The disc formed by the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 is positioned in the middle of the inner wall of the tank 1. The extension of the second electric push rod 203 drives the assembled disc downward. The extension distance of the second electric push rod 203 is recorded as "b". At this time, the air pressure below the assembled disc increases, increasing the force on the hydraulic sensor 107. The first pressure value measured by the hydraulic sensor 107 when the extension distance of the second electric push rod 203 is recorded as "b" is recorded. After a period of use... Before reuse, the filling cylinder 101 should be in the open state and the discharge pipe 104 should be in the closed state. The disc formed by the arc extension plate 303, the fixed arc plate 301 and the moving arc plate 302 should be located in the middle of the inner wall of the tank body 1. The extension distance of the second electric push rod 203 should be "b", which will drive the disc to move downward. Record the second pressure value measured by the hydraulic sensor 107 when the extension distance of the second electric push rod 203 is "b". Subtract the second pressure value from the first pressure value to calculate the difference. If the difference is greater than the second threshold set by the controller, it will be actively judged that there is a problem with the seal at the sealing disc 106 inside the discharge pipe 104. Then, the controller will remind the staff to perform timely maintenance to avoid affecting subsequent use.

[0053] Furthermore, during the initial use, when adding raw materials into tank 1, the regulating motor 208 drives the main bevel gear 209 to rotate, which in turn drives the fixed arc plates 301 on both sides to rotate, ensuring that both fixed arc plates 301 are in a vertical position, and the moving arc plates 302 on both sides are perpendicular to the fixed arc plates 301 on both sides. Figure 2 As shown, at this time, the stirring motor 201 drives the square seat 204 to rotate through the second electric push rod 203, which in turn drives the fixed arc plate 301 and the moving arc plate 302 to rotate, thereby breaking up the raw materials falling into the tank 1, so that the raw materials are evenly dispersed in the tank 1, avoiding the phenomenon of accumulation and clumping, which would affect the uniformity of mixing between the raw materials.

[0054] In addition, when the raw materials in tank 1 are stirred and mixed, the regulating motor 208 drives the fixed arc-shaped plates 301 on both sides to be in a cross-shaped state, such as... Figure 3As shown, the stirring motor 201 drives the square base 204 to rotate, thereby mixing the raw materials in the tank 1. At the same time, the forward and reverse rotation of the regulating motor 208 drives the fixed arc plates 301 on both sides to swing back and forth around the fixed axis 206. Furthermore, by intermittently starting the electromagnet 305, and when the electromagnet 305 is started, its magnetic poles are opposite to those of the permanent magnet block 304, the intermittent magnetic attraction of the electromagnet 305 to the permanent magnet block 304, under the action of the connecting base 306, the connecting rod 308, and the torsion spring 309, causes the moving arc plate 302 to swing. Thus, while the square base 204 rotates, the swinging of the fixed arc plate 301 and the moving arc plate 302 works together to further improve the mixing effect, making the mixing of the raw materials more uniform and thorough.

[0055] It should be noted that the reciprocating swing angle of the fixed arc plate 301 is between 0° and 90° to avoid the bottom of the fixed arc plate 301 on both sides colliding with the inner wall of the tank 1 during the rotation process. The swing amplitude of the moving arc plate 302 is also between 0° and 90° to prevent the moving arc plate 302 from colliding with the inner wall of the tank 1 during the rotation process.

[0056] Furthermore, during use, when the raw materials in tank 1 undergo a chemical reaction after stirring, the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 are recombined into a disc, and the disc is positioned above the liquid surface in tank 1, achieving a first-stage seal. At this time, the sealing cover 102 forms a second-stage seal, thereby improving the sealing effect of tank 1. When it is necessary to adaptively adjust the pressure inside tank 1, when the hydraulic sensor 107 detects that its pressure value is less than the third threshold set by the controller, it first puts the injection cylinder 101 into the open state. The extension of the second electric push rod 203 drives the disc composed of the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 to move downward, thereby increasing the pressure value in the cavity below the square seat 204, thus allowing for adjustments as needed. To increase the pressure inside tank 1, when the hydraulic sensor 107 detects that the pressure it receives is greater than the third threshold set by the controller, the electromagnet 305 is activated, and the magnetic poles between the electromagnet 305 and the permanent magnet block 304 are reversed. This allows the permanent magnet block 304 to be attracted by magnetic attraction, causing the arc-shaped extension plates 303 on both sides to move away from the square seat 204. At the same time, the moving arc-shaped plates 302 on both sides bend downwards, thus achieving pressure relief below the square seat 204 and reducing the pressure inside tank 1. The pressure inside tank 1 can be adaptively adjusted as needed, making the pressure inside tank 1 more compatible with the reaction between the raw materials, thereby improving the reaction effect between the raw materials and bringing the reaction between the raw materials to the optimal state. Since the injection cylinder 101 is in the open state at this time, the gas released by pressure relief can be discharged through the injection cylinder 101.

[0057] Finally, when it is necessary to discharge the liquid and residue from tank 1 after the reaction is completed, the discharge pipe 104 is opened. Then, the arc-shaped extension plate 303, the fixed arc plate 301, and the moving arc plate 302 are combined into a disc. The second electric push rod 203 drives the square seat 204 to move downward, thereby increasing the pressure at the bottom of the square seat 204. This pushes the material at the bottom of tank 1 out of the discharge pipe 104, effectively preventing material blockage at the discharge pipe 104 and accelerating the discharge of material. At the same time, when the disc formed by the arc-shaped extension plate 303, the fixed arc plate 301, and the moving arc plate 302 moves downward, its outer circumferential surface fits against the inner wall of tank 1, which can scrape off the material attached to the inner wall of tank 1, thereby cleaning the inner wall of tank 1.

[0058] Therefore, before use, this invention can combine the arc-shaped extension plate 303, the fixed arc-shaped plate 301, and the moving arc-shaped plate 302 into a disc, and sequentially use the rising and falling of the disc to test the sealing performance at the top of the tank 1, the filling cylinder 101, and the bottom of the discharge pipe 104. If a sealing problem occurs, timely reminders and maintenance can be provided to avoid affecting the production of cytosine during use. Furthermore, during the feeding process into the tank 1, by keeping the fixed arc-shaped plate 301 and the moving arc-shaped plate 302 vertical and perpendicular to each other, the rotation of the fixed arc-shaped plate 301 can disperse the incoming material, ensuring uniform distribution of the raw material within the tank 1 and preventing clumping. Additionally, during stirring, by making the fixed arc-shaped plates 301 and the moving arc-shaped plates 302 intersect on both sides, the rotation of the square base 204 can achieve mixing of the raw materials. The mixing and stirring process, along with the reciprocating oscillation of the fixed arc plate 301 and the moving arc plate 302, further enhances the uniformity and thoroughness of the mixing of the raw materials. Finally, after mixing, the invention can adaptively adjust the pressure inside the tank 1 by raising and lowering the disc formed by the arc extension plate 303, the fixed arc plate 301, and the moving arc plate 302, so that the pressure inside the tank 1 is more compatible with the reaction between the raw materials, thereby improving the reaction effect between the raw materials. Furthermore, during discharge, by moving the disc formed by the arc extension plate 303, the fixed arc plate 301, and the moving arc plate 302 downward, the material at the bottom of the tank 1 can be pushed out through the discharge pipe 104, which can effectively prevent material blockage at the discharge pipe 104 and accelerate the discharge of the material. At the same time, the outer circumference of the disc adheres to the inner wall of the tank 1, which can scrape off the material attached to the inner wall of the tank 1, thus cleaning the inner wall of the tank 1.
