[0006] Practical Content

[0007] The purpose of the present utility model is to provide an alkylation tube bundle reactor to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] An alkylation tube bundle reactor includes a reactor body, a liquid inlet pipe, and a liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe are respectively fixedly communicated with both sides of the reactor body. The surface of the reactor body is fixedly connected with a support frame, and the bottom of the support frame is fixedly installed with a plurality of sliding wheels;

[0011] Lifting mechanism, which is fixedly arranged on the stirring mechanism and can lift the precipitated material to improve the mixing effect of the material and the catalyst.

[0012] Preferably, the stirring mechanism includes a speed reducer fixedly installed at the bottom of the reactor body. The output end of the speed reducer is fixedly installed with a motor.

[0017] Preferably, a bearing seat is sleeved on the surface of the stirring rod and is connected to the reactor body through the bearing seat.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] 1. Considering that for some materials that are difficult to dissolve, it is very difficult to mix the material and the catalyst evenly by conventional stirring, which affects the quality of the final finished reaction solution. Therefore, by setting up a stirring mechanism, after placing the material and the catalyst in the reactor body, starting the motor to drive the speed reducer to rotate, the speed reducer will drive the stirring rod to rotate, and the stirring rod will drive the stirring blades to rotate, generating centrifugal force, so that the material and the catalyst can fully contact, improving the mixing effect.

[0020] 2. This utility model takes into account that some materials may precipitate at the bottom of the reactor body due to their high specific gravity, making it impossible for the materials to be fully mixed with the catalytic liquid. Therefore, by setting up a lifting mechanism, while the stirring rod rotates, it can drive the extrusion block to rotate. The hypotenuse part of the extrusion chute at the bottom of the extrusion block will contact the extrusion rod, and the extrusion rod will move downward under extrusion, driving the filter plate to move downward and simultaneously squeezing the spring. Then, when the extrusion block does not contact the extrusion rod, the elastic force generated by the spring will push the filter plate to move upward suddenly, simultaneously driving the materials to be lifted upward. By cycling in this way, the effect of preventing precipitation is achieved.

[0021] This utility model generates centrifugal force through the setting of a stirring mechanism, enabling the materials to be in full contact with the catalyst, improving the mixing effect. At the same time, during the stirring process, the materials will impact on the impact rod, decomposing the materials into smaller particles, increasing the contact area between the materials and the catalyst, further improving the mixing effect. Moreover, the lifting mechanism drives the materials to be lifted upward, achieving the effect of preventing precipitation, and solving the problem that for some difficult-to-dissolve materials, it is very difficult to mix the materials and the catalyst evenly through conventional stirring, which affects the quality of the final finished reaction liquid.

Obviously, the described embodiments are only a part of the embodiments of the present utility, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility without creative efforts shall fall within the protection scope of the present utility.

[0030] Please refer to Figures 1 - 6 , the present utility provides a technical solution:

[0031] Embodiment 1:

[0032] An alkylation tube bundle reactor includes a reactor body 1, a liquid inlet pipe 2 and a liquid outlet pipe 3. The liquid inlet pipe 2 and the liquid outlet pipe 3 are respectively fixedly communicated with both sides of the reactor body 1. A support frame 4 is fixedly connected to the surface of the reactor body 1, and a plurality of sliding wheels 5 are fixedly installed at the bottom of the support frame 4;

[0033] A stirring mechanism is fixedly arranged on the reactor body 1, which can make the material and the catalyst fully contact through stirring, and at the same time can impact the material to disperse it into small particles, so as to make the material and the catalyst mix evenly;

[0034] A lifting mechanism is fixedly arranged on the stirring mechanism, which can lift the precipitated material and improve the mixing effect of the material and the catalyst.

[0035] One implementation manner of this Embodiment 1 is that the stirring mechanism includes a speed reducer 6 fixedly installed at the bottom of the reactor body 1. The output end of the speed reducer 6 is fixedly installed with a motor 7. The transmission end of the speed reducer 6 penetrates to the top of the reactor body 1 and is fixedly connected with a stirring rod 19. Stirring blades 8 are fixedly connected to the surface of the stirring rod 19, and a plurality of impact rods 9 are fixedly connected to both the top and the bottom of the stirring blades 8;

[0036] In this embodiment, considering that for some materials that are difficult to dissolve, it is very difficult to mix the material and the catalyst evenly through conventional stirring, which affects the quality of the final finished reaction solution. Therefore, by setting the stirring mechanism, after the material and the catalyst are placed in the reactor body 1, the motor 7 is started to drive the speed reducer 6 to rotate. The speed reducer 6 will drive the stirring rod 19 to rotate, and the stirring rod 19 will drive the stirring blades 8 to rotate, generating a centrifugal force, so that the material and the catalyst are fully contacted, improving the mixing effect. At the same time, during the stirring process, the material will impact on the impact rods 9, decomposing the material into smaller particles, increasing the contact area between the material and the catalyst, and further improving the mixing effect;

[0037] It solves the problem that for some difficult-to-dissolve materials, it is very difficult to mix the materials and the catalyst evenly by conventional stirring, which affects the quality of the final product reaction solution.

[0038] Preferably, a plurality of filter holes 17 are formed on the surface of the stirring blade 8;

[0039] In this embodiment, by providing the filter holes 17, during the rotation of the stirring blade 8, the resistance of the stirring blade 8 in the catalyst can be reduced, making its rotation smoother, and the losses of the motor 7 and the speed reducer 6 can also be reduced, improving the service life.

[0040] Preferably, a bearing seat 18 is sleeved on the surface of the stirring rod 19, and the stirring rod 19 is rotationally connected to the inner wall of the reactor body 1 through the bearing seat 18;

[0041] In this embodiment, by providing the bearing seat 18, it can play a role in supporting structures such as the stirring rod 19, and at the same time limit the position of the stirring rod 19, making its rotation more stable.

[0042] Embodiment Two:

[0043] On the basis of Embodiment One, in this embodiment, the stirring mechanism can generate centrifugal force and impact on the materials through stirring, breaking them into small pieces to improve the mixing effect. However, considering that some materials may precipitate at the bottom of the reactor body 1 due to high specific gravity, resulting in insufficient mixing of the materials and the catalytic liquid. In this application, the lifting mechanism includes a filter plate 10 sleeved on the surface of the stirring rod 19. Two springs 11 are fixedly connected to the bottom of the filter plate 10, and the bottoms of the springs 11 are fixedly connected to the inner wall of the reactor body 1. Two extrusion rods 12 are fixedly connected to the top of the filter plate 10. Extrusion blocks 13 used in cooperation with the extrusion rods 12 are fixedly connected to both sides of the stirring rod 19;

[0044] In this embodiment, considering that some materials may precipitate at the bottom of the reactor body 1 due to high specific gravity, resulting in insufficient mixing of the materials and the catalytic liquid. Therefore, by providing the lifting mechanism, while the stirring rod 19 rotates, it can drive the extrusion block 13 to rotate. The hypotenuse part of the extrusion inclined groove 16 at the bottom of the extrusion block 13 will contact the extrusion rod 12. Under the extrusion, the extrusion rod 12 will move downward, driving the filter plate 10 to move downward, and at the same time squeezing the spring 11. Then when the extrusion block 13 does not contact the extrusion rod 12, the elastic force generated by the spring 11 will push the filter plate 10 to move suddenly upward, simultaneously driving the materials to be lifted upward. This cycle is repeated to achieve the effect of preventing precipitation;

[0045] It solves the problem that considering that some materials may precipitate at the bottom of the reactor body 1 due to high specific gravity, resulting in insufficient mixing of the materials and the catalytic liquid.

[0046] Preferably, guide blocks 14 are fixedly connected to both sides of the filter plate 10, and guide grooves 15 adapted to the guide blocks 14 are provided on the inner wall of the reactor body 1;

[0047] In this embodiment, by providing the guide blocks 14 and the guide grooves 15, a moving trajectory can be provided for the filter plate 10. When the extrusion block 13 contacts and extrudes the extrusion rod 12, the extrusion rod 12 can only drive the filter plate 10 to move downward along the trajectories of the guide blocks 14 and the guide grooves 15.

[0048] Preferably, one end of the extrusion rod 12 is spherical, and an extrusion inclined groove 16 adapted to the extrusion rod 12 is provided at the bottom of the extrusion block 13;

[0049] In this embodiment, by providing the extrusion inclined groove 16, when the hypotenuse part of the extrusion inclined groove 16 at the bottom of the extrusion block 13 contacts the extrusion rod 12, the extrusion rod 12 will move downward under extrusion, driving the filter plate 10 to move downward, playing a role in transmission.

[0050] Working principle: After placing the material and the catalyst in the reactor body 1, start the motor 7 to drive the speed reducer 6 to rotate. The speed reducer 6 will drive the stirring rod 19 to rotate, and the stirring rod 19 will drive the stirring blades 8 to rotate, generating a centrifugal force, so that the material and the catalyst are fully contacted, improving the mixing effect. At the same time, during the stirring process, the material will impact on the impact rod 9, decomposing the material into smaller particles, increasing the contact area between the material and the catalyst, and further improving the mixing effect;

[0051] While the stirring rod 19 is rotating, it drives the extrusion block 13 to rotate. The hypotenuse part of the extrusion inclined groove 16 at the bottom of the extrusion block 13 contacts the extrusion rod 12. The extrusion rod 12 will move downward under extrusion, driving the filter plate 10 to move downward, and at the same time squeezing the spring 11. Then when the extrusion block 13 does not contact the extrusion rod 12, the elastic force generated by the spring 11 will push the filter plate 10 to move upward suddenly, simultaneously driving the material to be lifted upward. By this cycle, the function of preventing precipitation is achieved.

[0052] It should be noted that the motor 7 and the speed reducer 6 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. And the specific composition and principle of the power supply of the motor 7 and the speed reducer 6 are clear to those skilled in the art, so no further details will be described.

The scope of the present utility is defined by the appended claims and their equivalents.
