The alkylation reactor cools the materials in the reactor by cold air to facilitate the fusion of the materials, and accelerates the fusion of the materials by stirring the materials with a stirring rod. The stirring rod is corrosion-resistant to avoid corrosion of the device by the fused materials, thereby protecting the safety and protection of the device.

[0004] However, the above device still has the following problems during implementation:

[0005] In the prior art and the above-mentioned scheme, the stirring rod stirs the materials to accelerate the fusion of the materials so as to improve the mixing effect of the alkylation reactor. However, during the stirring process, the following problems still exist, which will also affect the mixing effect:

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 , the utility model provides a technical solution:

[0032] Embodiment 1:

[0033] A high-efficiency alkylation reactor comprises a base 1 and an alkylation reactor 2. The alkylation reactor 2 is fixedly installed on the top of the base 1. The top of the alkylation reactor 2 is fixedly connected with a liquid inlet 3 and a gas inlet 4, respectively. One side of the alkylation reactor 2 is fixedly connected with a cold air inlet 5. The other side of the alkylation reactor 2 is fixedly connected with a cold air outlet 6. The interior of the alkylation reactor 2 is provided with a stirring and clearing mechanism, which can clear the materials adhering to the bottom of the alkylation reactor 2.

[0034] The pressing mechanism is movably arranged inside the alkylation reactor 2. When the stirring and removing mechanism stirs, it drives the pressing mechanism to press down the agglomerated and floating materials so that the materials can be fully contacted with the catalyst.

[0035] One implementation of the first embodiment is as follows: the stirring and clearing mechanism includes a housing 7 fixedly mounted on the top of the alkylation reactor 2, a motor 8 is arranged inside the housing 7, an output end of the motor 8 penetrates into the interior of the alkylation reactor 2, and is fixedly connected to a stirring rod 9, a stirring blade 10 is fixedly connected to the surface of the stirring rod 9, and a scraper 11 is fixedly connected to the bottom of the stirring rod 9;

[0036] In this embodiment, it is considered that when the materials are added to the alkylation reactor 2 and mixed, some of the materials may contact with the catalyst and sink, and adhere to the bottom of the inner wall of the alkylation reactor 2. Therefore, by providing a stirring and removing mechanism, after the materials enter the alkylation reactor 2, the motor 8 is started to drive the stirring rod 9 and the stirring blade 10 to rotate, so that the materials and the catalyst are fully mixed. At the same time, the stirring rod 9 also drives the scraper 11 to rotate. During the rotation of the scraper 11, the materials adhering to the bottom of the inner wall of the alkylation reactor 2 will be dropped, thereby effectively improving the mixing effect.

[0037] The problem that when materials are added to the alkylation reactor 2 for mixing, part of the materials may sink due to contact with the catalyst and adhere to the bottom of the inner wall of the alkylation reactor 2, which also affects the mixing effect, is solved.

[0038] Preferably, a bearing seat 14 is fixedly mounted on the inner wall of the alkylation reactor 2, and the bearing seat 14 is rotatably connected to the stirring rod 9;

[0039] This embodiment takes into account the existence of structures such as the scraper 11 and the stirring rod 9 on the stirring rod 9, which may cause shaking when the motor 8 rotates. Therefore, by providing a bearing seat 14, the position of the stirring rod 9 can be limited, the stirring rod 9 can be supported, and the stability of the stirring rod 9 when rotating can be improved.

[0040] Preferably, the number of the scrapers 11 is two, and the outer surface thereof is in close contact with the inner wall of the alkylation reactor 2;

[0041] In this embodiment, a scraper 11 is provided. Since the outer surface of the scraper 11 is in close contact with the inner wall of the alkylation reactor 2, when the stirring rod 9 drives the scraper 11 to rotate, the material adhered to the inner wall of the alkylation reactor 2 can be removed.

[0042] Embodiment 2:

[0043] On the basis of the first embodiment, the stirring and removing mechanism in this embodiment can hang off the material adhered to the inner wall of the alkylation reactor 2, but considering that when the material is added to the alkylation reactor 2 for mixing, the material will agglomerate when it contacts the catalyst in the alkylation reactor 2, and will float close to the inner wall of the alkylation reactor 2 under the action of centrifugal force during the stirring process, resulting in the catalyst being unable to fully contact the material, and also affecting the mixing efficiency. In this application, the pressing mechanism includes a pressing ring 12 movably arranged inside the alkylation reactor 2, and the top of the pressing ring 12 is fixedly connected to a plurality of springs 13, and the top of the spring 13 is fixedly connected to the inner wall of the alkylation reactor 2, and the bottom of the pressing ring 12 is fixedly connected to a plurality of extrusion rods 15, and the number of the extrusion rods 15 is a plurality;

[0044] Both sides of the stirring rod 9 are fixedly connected with a transmission rod 16, and the top of the transmission rod 16 is fixedly connected with an extrusion block 17;

[0045] In this embodiment, it is considered that when the material is added to the alkylation reactor 2 for mixing, the material will agglomerate when it contacts the catalyst in the alkylation reactor 2, and will float close to the inner wall of the alkylation reactor 2 under the action of centrifugal force during the stirring process, resulting in the catalyst being unable to fully contact the material. Therefore, by providing a downward pressing mechanism, the driving rod 16 and the extrusion block 17 can be driven to rotate during the rotation of the stirring rod 9, such as Figure 6 As shown, when the sloped portion of the surface of the extrusion block 17 contacts the spherical portion of the extrusion rod 15, the extrusion rod 15 and the lower pressure ring 12 will move upward to compress the spring 13. When the extrusion block 17 rotates to no longer contact the extrusion rod 15, the reaction force of the spring 13 will drive the lower pressure ring 12 and the extrusion rod 15 to move downward, thereby pressing the material blocks floating on the surface of the catalyst into the catalyst, and the cycle is repeated in sequence to achieve the effect of intermittently pressing the material blocks into the catalyst so that they are in full contact with the catalyst.

[0046] Preferably, two guide rods 18 are fixedly connected to the inner wall of the alkylation reactor 2, and a guide hole 19 for use with the guide rods 18 is provided on the top of the lower pressure ring 12;

[0047] This embodiment takes into account the stability of the lower pressure ring 12 when it rebounds and is pressed down. Therefore, by providing a guide rod 18 and a guide hole 19, the movement trajectory of the lower pressure ring 12 and other structures can be limited so that it can only move up and down along the guide rod 18.

[0048] Preferably, both sides of the extrusion block 17 are sloped, and the bottom of the extrusion rod 15 is spherical;

[0049] In this embodiment, by setting an extrusion block 17 and an extrusion rod 15, the two sides of the extrusion block 17 are set to a slope shape and the bottom of the extrusion rod 15 is set to a spherical shape. When the slope part of the surface of the extrusion block 17 contacts the spherical part of the extrusion rod 15, the extrusion rod 15 and the lower pressure ring 12 will move upward, thereby playing a transmission role.

[0050] Working principle: When the material enters the alkylation reactor 2, the motor 8 is started to drive the stirring rod 9 and the stirring blade 10 to rotate, so that the material and the catalyst are fully mixed. At the same time, the stirring rod 9 also drives the scraper 11 to rotate. During the rotation of the scraper 11, the material adhering to the bottom of the inner wall of the alkylation reactor 2 will be dropped, thereby effectively improving the mixing effect;

[0051] During the rotation of the stirring rod 9, the transmission rod 16 and the extrusion block 17 are driven to rotate. Figure 6As shown, when the sloped portion of the surface of the extrusion block 17 contacts the spherical portion of the extrusion rod 15, the extrusion rod 15 and the lower pressure ring 12 will move upward to compress the spring 13. When the extrusion block 17 rotates to no longer contact the extrusion rod 15, the reaction force of the spring 13 will drive the lower pressure ring 12 and the extrusion rod 15 to move downward, thereby pressing the material blocks floating on the surface of the catalyst into the catalyst, and the cycle is repeated in sequence to achieve the effect of intermittently pressing the material blocks into the catalyst so that they are in full contact with the catalyst.

[0052] It should be noted that the motor 8 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 8 are clear to those skilled in the art, so they are not described in detail.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
