Description

Technical Field

[0001] The present invention relates to the technical field of reaction kettles, and particularly to a self-feeding reaction kettle for high-viscosity media. Background Art

[0002] In many industrial fields such as chemical industry, pharmaceuticals, and food, reaction kettles are key equipment for carrying out chemical reactions, mixing and preparing substances. To ensure the normal progress of the reaction process and the quality of the final product meeting the requirements, it is crucial to sample and analyze the materials in the reaction kettle in real time and accurately. Traditional sampling methods for reaction kettles mainly rely on manual operation. Operators need to wear protective equipment at specific time points, manually open the sampling port of the reaction kettle, and use sampling tools to collect samples deep inside the reaction kettle. However, this sampling method has many drawbacks. The inside of the reaction kettle is often in a high-temperature, high-pressure, toxic, harmful, flammable, or explosive environment. When sampling manually, operators are directly exposed to these dangerous conditions, which can easily lead to serious safety accidents. Moreover, when sampling the products inside the reaction kettle, samples are usually taken from arbitrary positions inside the reaction kettle, and the data obtained from the samples is not rich enough, resulting in inaccurate inspection results. Summary of the Invention

[0049] As Figure 1-18 shown, a high-viscosity medium self-feeding reactor includes a reactor body 10, a sampling assembly, and a stirring assembly 40. The stirring assembly 40 includes a stirring rod 401 rotatably disposed in the reactor body 10 and a stirring drive motor 402 disposed at the bottom of the reactor body 10 and drivingly connected to the stirring rod 401. The stirring rod 401 is a hollow tubular body;

[0050] The sampling assembly includes a sampling unit 20 and an extraction unit 30. The sampling unit 20 includes a first sampling tube 201 sleeved in the stirring rod 401, a second sampling tube 202 sleeved in the first sampling tube 201, a third sampling tube 203 sleeved in the second sampling tube 202, and a driving unit 204 drivingly connected to the first sampling tube 201, the second sampling tube 202, and the third sampling tube 203 respectively. A first sampling port 2011 is formed on the outer side of the bottom end of the first sampling tube 201, and a first inlet 4011 corresponding to the first sampling port 2011 is formed on the side surface of the stirring rod 401. The bottom end of the second sampling tube 202 extends out of the first sampling tube 201 and is provided with a first sampling disc 2021. The outer side of the first sampling disc 2021 is in contact with the inner wall of the stirring rod 401 and can rotate relatively. A second sampling port 2022 is formed on the side surface of the first sampling disc 2021, and a second inlet 4012 corresponding to the second sampling port 2022 is formed on the outer side of the stirring rod 401. The bottom end of the third sampling tube 203 extends out of the second sampling tube 202 and is provided with a second sampling disc 2031. A third sampling port 2032 is formed on the outer side of the second sampling disc 2031, and a third inlet 4013 corresponding to the third sampling port 2032 is formed on the outer side of the stirring rod 401;

[0051] The extraction unit 30 is installed on the side surface of the kettle body 10 and is respectively communicated with the first sampling tube 201, the second sampling tube 202, and the third sampling tube 203, so as to be adapted to sample the high-viscosity medium in the kettle body 10 through the first sampling tube 201, the second sampling tube 202, and the third sampling tube 203.

[0052] With the above arrangement, during operation, the stirring drive motor 402 drives the stirring rod 401 to rotate to stir the sample in the kettle body 10. When sampling is required, the stirring drive motor 402 drives the stirring rod 401 to reduce the rotation speed and continue to rotate until it stops at a preset angle. Then, the operator can sample products at different depths in the kettle body 10 according to specific needs. Specifically, when the operator needs to sample the deep product sample in the kettle body 10, the driving unit 204 drives the third sampling tube 203 to rotate so that the third sampling port 2032 provided on the side of the second sampling disk 2031 is aligned with the third inlet 4013 provided on the outer side of the stirring rod 401. Then, the extraction unit 30 is started for extraction. The product in the kettle body 10 will flow through the third inlet 4013 and the third sampling port 2032. The third sampling tube 203 is then driven by the driving unit 204 to rotate in the opposite direction, so that the third sampling port 2032 is staggered with the third inlet 4013, and the third sampling tube 203 is separated from the kettle body 10. Then the extraction unit 30 continues to work, and the product in the third sampling tube 203 is extracted into a preset sample storage container to complete the sampling of the deep product in the kettle body 10. This method can avoid that part of the product remains in the third sampling tube 203 after sampling, causing the third sampling tube 203 to be blocked; and when it is necessary to extract products at other depths, it is only necessary to use the driving unit 204 to drive the sampling tube of the corresponding depth, which is not described in detail here. In addition, since the sampling tubes corresponding to each depth are independently arranged, it can effectively avoid that products at different depths are mixed with each other during sampling, thereby affecting the purity of the obtained sample.

[0053] In addition, in order to heat the product in the kettle body 10 , a heating resistance wire is embedded in the inner wall of the kettle body 10 in this embodiment.

[0054] The present invention utilizes the first sampling tube 201, the second sampling tube 202 and the third sampling tube 203 arranged in the stirring rod 401 to sample products at different depths in the kettle body 10. At the same time, the independent sampling tubes can effectively avoid the mixing of samples at different depths during sampling, resulting in low purity of the samples and affecting the accuracy of the inspection.

[0055] Specifically, in order to drive the first sampling tube 201, the second sampling tube 202, and the third sampling tube 203 to rotate, in the present invention, the driving unit 204 includes a first linkage gear 2041 installed at the top end of the first sampling tube 201, a second linkage gear 2042 installed at the top end of the second sampling tube 202, a third linkage gear 2043 installed at the top end of the third sampling tube 203, a transmission unit 205 that is in transmission connection with the first linkage gear 2041, the second linkage gear 2042, and the third linkage gear 2043, and a sampling driving motor 206 that is in transmission connection with the transmission unit 205. The transmission unit 205 includes a first transmission gear 2051 that is in transmission connection with the first linkage gear 2041, a second transmission gear 2052 that is in transmission connection with the second linkage gear 2042, a third transmission gear 2053 that is in transmission connection with the third linkage gear 2043, and a switching member 207 for transmitting the sampling driving motor 206 to the first transmission gear 2051 or the second transmission gear 2052 or the third transmission gear 2053.

[0056] During operation, the operator adjusts the sampling tube in transmission connection with the sampling driving motor 206 through the switching member 207 according to the depth of the sample to be collected, and then starts the sampling driving motor 206 to control the rotation of the sampling tube at the corresponding depth, so as to sample when the sampling port in the sampling tube is aligned with the inlet on the stirring rod 401.

[0057] In order to improve the accuracy when the sampling port on the sampling tube is aligned with the inlet on the stirring rod 401, in this embodiment, angle inspection sensors are also provided on the first linkage gear 2041, the second linkage gear 2042, the third linkage gear 2043, and the stirring rod 401, which are used to detect the angles of the first sampling tube 201, the second sampling tube 202, the third sampling tube 203, and the stirring rod 401, calculate the angle that the corresponding sampling tube needs to rotate when the sampling port on the sampling tube is aligned with the inlet on the stirring rod 401, and then control the sampling driving motor 206 to drive the corresponding sampling tube to rotate by the corresponding angle so that the sampling port is aligned with the inlet.

[0058] In addition, in order to adjust the rotation speed, adjusting gears can also be provided between the first linkage gear 2041, the second linkage gear 2042, the third linkage gear 2043 and the first transmission gear 2051, the second transmission gear 2052, the third transmission gear 2053.

[0059] Specifically, in the present invention, the switching member 207 includes a first mounting rod 2071 installed at the top end of the kettle body 10 and slidable along the axial direction of the kettle body 10, a first driven gear 2072, a first face gear 2073, a second driven gear 2074, and a second face gear 2075 that are sequentially arranged at intervals from top to bottom along the axial direction of the first mounting rod 2071, a driving member for driving the first mounting rod 2071 to move axially along the kettle body 10, a third face gear 2076 fixedly connected to the upper end face of the first transmission gear 2051, and a fourth face gear 2077 fixedly connected to the lower end face of the third transmission gear 2053. A driving end of the sampling driving motor 206 is installed with a driving gear 2061, and the driving gear 2061 meshes with the first driven gear 2072. The first mounting rod 2071 is adapted to drive the first face gear 2073, the second driven gear 2074, and the second face gear 2075 to rotate under the drive of the sampling driving motor 206, and the second driven gear 2074 is adapted to mesh with the second transmission gear 2052;

[0060] When the first mounting rod 2071 moves upward along the axial direction of the kettle body 10 under the drive of the driving member, the second driven gear 2074 is separated from the second transmission gear 2052, and the first face gear 2073 meshes with the fourth face gear 2077;

[0061] When the first mounting rod 2071 moves downward along the axial direction of the kettle body 10 under the drive of the driving member, the second driven gear 2074 is separated from the second transmission gear 2052, and the second face gear 2075 meshes with the third face gear 2076.

[0062] When in the initial state, the second driven gear 2074 is in mesh with the second transmission gear 2052. If the staff needs to sample the middle-layer product in the kettle body 10 using the second sampling tube 202, they can directly control the sampling drive motor 206 to start, so that the second sampling port 2022 is aligned with the second inlet 4012 for sampling. When it is necessary to sample the deep-layer product in the kettle body 10, the driving member drives the first mounting rod 2071 to move upward along the axial direction of the kettle body 10, and the second driven gear 2074 is separated from the second transmission gear 2052, and the first end face gear 2073 is in mesh with the fourth end face gear 2077. At this time, the sampling drive motor 206 can drive the third sampling tube 203 to rotate, so that the third sampling tube 203 is aligned with the third inlet 4013 for sampling. When the staff needs to sample the shallow-layer product in the kettle body 10, the driving member drives the first mounting rod 2071 to move downward along the axial direction of the kettle body 10, and the second driven gear 2074 is separated from the second transmission gear 2052, and the second end face gear 2075 is in mesh with the third end face gear 2076. At this time, the sampling drive motor 206 can drive the first sampling tube 201 to rotate, so that the first sampling tube 201 is aligned with the first inlet 4011 for sampling. After sampling is completed, the driving member drives the first mounting rod 2071 to return to the initial state. To facilitate the return to the initial state when the second driven gear 2074 is in mesh with the second transmission gear 2052, a guiding inclined surface is provided at the edge of the teeth of the second driven gear 2074 and the teeth of the second transmission gear 2052, so that after the end face of the second driven gear 2074 contacts the end face of the second transmission gear 2052, the teeth of the second driven gear 2074 or the teeth of the second transmission gear 2052 slide along the guiding inclined surface and mesh.

[0063] In addition, since the first driven gear 2072 is fixedly connected to the first mounting rod 2071 and will move axially together with the first mounting rod 2071, in order to prevent the first driven gear 2072 from being separated from the driving gear 2061 during the axial movement of the first driven gear 2072 together with the first mounting rod 2071, in this embodiment, the tooth thickness of the first driven gear 2072 is greater than or equal to the maximum axial movement distance of the first mounting rod 2071.

[0064] In addition, to facilitate the installation of the first transmission gear 2051, the second transmission gear 2052, and the third transmission gear 2053, in this embodiment, the transmission unit 205 further includes a second mounting rod 2054. The third transmission gear 2053, the second transmission gear 2052, and the first transmission gear 2051 are sequentially sleeved on the second mounting rod 2054 at intervals from top to bottom and can rotate or slide relative to the second mounting rod 2054;

[0065] Meanwhile, to prevent the first sampling tube 201, the second sampling tube 202, and the third sampling tube 203 from rotating together with the stirring rod 401 when not sampling, in this embodiment, the driving unit 204 further includes a locking member 2044. The locking member 2044 includes a first tooth ring 20441 installed on the lower end face of the fourth end face gear 2077, a second tooth ring 20443 installed on the upper end face of the second transmission gear 2052, a third tooth ring 20445 installed on the lower end face of the second transmission gear 2052, a fourth tooth ring 20447 installed on the upper end face of the third end face gear 2076, and a first snap ring 20442, a second snap ring 20444, a third snap ring 20446, and a fourth snap ring 20448 fixedly arranged on the outside of the second mounting rod 2054 and arranged in sequence from top to bottom along the axial direction of the second mounting rod 2054. The first tooth ring 20441 is adapted to mesh with the first snap ring 20442, the fourth tooth ring 20447 is adapted to mesh with the fourth snap ring 20448, the second tooth ring 20443 is adapted to mesh with the second snap ring 20444, the third tooth ring 20445 is adapted to mesh with the third snap ring 20446, and a first elastic member 20449 is arranged between the second tooth ring 20443 and the second snap ring 20444 and between the third tooth ring 20445 and the third snap ring 20446;

[0066] A first top plate 2078 is arranged between the first end face gear 2073 and the second driven gear 2074, a second top plate 2079 is arranged between the second end face gear 2075 and the second driven gear 2074, and the first top plate 2078 and the second top plate 2079 are fixedly connected to the first mounting rod 2071;

[0067] When in the initial state, the second transmission gear 2052 is in an intermediate state under the action of the two first elastic members 20449, that is, the second tooth ring 20443 does not engage with the second snap ring 20444, and the third tooth ring 20445 does not engage with the third snap ring 20446. At this time, the second transmission gear 2052 engages with the second driven gear 2074 and can rotate under the drive of the sampling drive motor 206 to drive the second sampling tube 202 to rotate for sampling. When the staff needs to sample the deep-layer product of the kettle body 10, when the first mounting rod 2071 moves upward along the axial direction of the kettle body 10 under the drive of the driving member, the second top plate 2079 abuts against the lower end surface of the second transmission gear 2052 to drive the second transmission gear 2052 to move upward, so that the second tooth ring 20443 engages with the second snap ring 20444. At the same time, the first end face gear 2073 engages with the fourth end face gear 2077 and drives the fourth end face gear 2077 to move upward, so that the first tooth ring 20441 is separated from the first snap ring 20442. At this time, the sampling drive motor 206 is in transmission connection with the third sampling tube 203, and the sampling drive motor 206 can drive the third sampling tube 203 to rotate so that the third sampling tube 203 is aligned with the third inlet 4013 for sampling. When the staff needs to sample the deep-layer product of the kettle body 10, when the first mounting rod 2071 moves downward along the axial direction of the kettle body 10 under the drive of the driving member, the first top plate 2078 abuts against the upper end surface of the second transmission gear 2052 to drive the second transmission gear 2052 to move downward, so that the third tooth ring 20445 engages with the third snap ring 20446. At the same time, the second end face gear 2075 engages with the third end face gear 2076 and drives the third end face gear 2076 to move downward, so that the fourth tooth ring 20447 is separated from the fourth snap ring 20448. At this time, the sampling drive motor 206 is in transmission connection with the first sampling tube 201, and the sampling drive motor 206 can drive the first sampling tube 201 to rotate so that the first sampling tube 201 is aligned with the first inlet 4011 for sampling.

[0068] In this embodiment, the driving member can adopt a linear driving mechanism such as a driving cylinder. A fixing plate is installed at the driving end of the driving cylinder. The first mounting rod 2071 passes through the fixing plate and is rotatably connected to the fixing plate. Thus, the first mounting rod 2071 can be driven to move upward or downward along the axis of the kettle body 10 by driving the fixing plate to move up and down by the driving cylinder. At the same time, to prevent the fixing plate from tilting during movement, a slide rail slidably connected to one end of the fixing plate can be provided on the kettle body 10, and a guide rod passing through the fixing plate can be provided to limit the movement direction of the fixing plate and prevent it from shifting during movement.

[0069] In addition, in order to ensure that when the first top plate 2078 and the second top plate 2079 come into contact with and abut against the second transmission gear 2052, the second driven gear 2074 and the second transmission gear 2052 have been completely separated. Therefore, in this embodiment, the distance between the second driven gear 2074 and the first top plate 2078 and the second top plate 2079 is set to be greater than or equal to the tooth thickness of the second transmission gear 2052. With this setting, the first top plate 2078 or the second top plate 2079 can abut against the second transmission gear 2052 and drive it upward or downward after the second driven gear 2074 is completely separated from the second transmission gear 2052, rather than abutting against the second transmission gear 2052 and driving it to move together when the second driven gear 2074 and the second transmission gear 2052 are still in the meshed state.

[0070] Meanwhile, in order to ensure that the second transmission gear 2052 can still remain in the meshed state with the second linkage gear 2042 during the upward or downward movement driven by the first top plate 2078 or the second top plate 2079. Therefore, in this embodiment, the distance from the second tooth ring 20443 to the second snap ring 20444 is equal to the distance from the third tooth ring 20445 to the third snap ring 20446, and is less than the tooth thickness of the second transmission gear 2052. With this setting, the maximum upward or downward movement stroke of the second transmission gear 2052 will not exceed the thickness of the second transmission gear 2052, and the tooth thickness of the second transmission gear 2052 is equal to the tooth thickness of the second linkage gear 2042. Therefore, after the second transmission gear 2052 moves upward or downward driven by the first top plate 2078 or the second top plate 2079, it will still remain in the meshed state with the second linkage gear 2042 and will not separate. Of course, in this embodiment, the tooth thickness of the second transmission gear 2052 or the second linkage gear 2042 can also be increased to ensure that the second transmission gear 2052 always remains in the meshed state with the second linkage gear 2042 during the movement.

[0071] In addition, in order to ensure that the first snap ring 20442 and the first tooth ring 20441, as well as the fourth snap ring 20448 and the fourth tooth ring 20447, always remain in the meshed state when not working. Therefore, in this embodiment, the locking member 2044 further includes two second elastic members 204410, and the two second elastic members 204410 are respectively arranged on the lower end surface of the first transmission gear 2051 and the upper end surface of the third transmission gear 2053, so as to utilize the elasticity of the second elastic members 204410 to make the fourth tooth ring 20447 installed on the upper end surface of the third end face gear 2076 mesh with the fourth snap ring 20448, and the first tooth ring 20441 installed on the lower end surface of the fourth end face gear 2077 mesh with the first snap ring 20442.

[0072] Preferably, in this embodiment, the stirring assembly 40 further includes fixing rings 403 installed at both ends of the stirring rod 401, fixing rods 404 arranged uniformly along the axial direction of the fixing rings 403, and worms 405 rotatably installed at the ends of the fixing rods 404. The worms 405 extend along the axial direction of the kettle body 10, and worm gears 406 are installed at both ends of the worms 405. A ring-shaped rack 407 meshing with the worm gears 406 is arranged in the kettle body 10.

[0073] During operation, the stirring drive motor 402 drives the stirring rod 401 to rotate. The stirring rod 401 drives the worms 405 to rotate around the stirring rod 401 through the fixing rings 403 and fixing rods 404 to stir the products in the kettle body 10. During the rotation of the worms 405, the ring-shaped rack 407 will drive the worms 405 to rotate self - axially through the worm gears 406, further improving the mixing efficiency.

[0074] Preferably, in this embodiment, the extraction unit 30 includes a connecting flange 301, a plurality of connecting pipes 302, sampling cylinders 303 provided corresponding to the plurality of connecting pipes 302 one by one, and sampling pistons 304 provided corresponding to the plurality of sampling cylinders 303 one by one. The plurality of connecting pipes 302 are connected to the first sampling pipe 201, the second sampling pipe 202, and the third sampling pipe 203 through the connecting flange 301.

[0075] Specifically, in this embodiment, the tops of the first sampling pipe 201, the second sampling pipe 202, and the third sampling pipe 203 all extend out of the top of the kettle body 10, and a connecting flange 301 is rotatably connected to each of them. Then, a connecting pipe 302 is connected to each connecting flange 301, a sampling cylinder 303 is connected to the end of the connecting pipe 302, and the sampling cylinder 303 is connected to the sampling piston 304. With this setting method, the sampling piston 304 can draw the products into the sampling cylinder 303 through the first sampling pipe 201, the second sampling pipe 202, and the third sampling pipe 203. And for the convenience of taking out the samples in the sampling cylinder 303, a sampling pipe communicating with the outside is provided on the side wall of the sampling cylinder 303. And to prevent the products in the sampling cylinder 303 from flowing back into the first sampling pipe 201, the second sampling pipe 202, or the third sampling pipe 203, a one - way valve is provided at the connection end of the connecting pipe 302 and the sampling cylinder 303 to limit the flow direction of the products.
