Description

Technical Field

[0001] The invention belongs to the technical field of reaction kettles, in particular to a fluorination reaction kettle. Background Art

[0002] The fluorination reactor is a reactor specially used for fluorination reactions. A corresponding stirring paddle is installed in the cylinder of the fluorination reactor. Through stirring, the materials in the reactor are mixed and reacted under high temperature, high pressure or cooling and constant temperature conditions to produce ideal products.

[0003] In the existing fluorination reaction kettle, when anhydrous hydrogen fluoride is introduced into the solution to be fluorinated and mixed by stirring and heating, the anhydrous hydrogen fluoride is easily gasified by heat, and the anhydrous hydrogen fluoride expands, so that the gaseous anhydrous hydrogen fluoride floats upward, resulting in that part of the anhydrous hydrogen fluoride cannot be fully mixed and stirred with the solution. In addition, since the anhydrous hydrogen fluoride is added from the liquid surface of the solution, it takes a long time of stirring and heating to fully mix the bottom with the anhydrous hydrogen fluoride, which greatly reduces the reaction efficiency. Therefore, it is necessary to improve it. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The above technical solution is provided with a one-way conveying component and a transmission component. When the stirring rod rotates as a whole to stir the solution inside the reactor body, the one-way conveying component can be driven as a whole to operate by the transmission component, so that the anhydrous hydrogen fluoride introduced into the liquid inlet pipe can be smoothly one-way conveyed to the inside of the solution.

When the bottom of the liquid inlet pipe is idle, the outer end of the dustproof component can be used to block and seal the bottom of the liquid inlet pipe, thereby preventing external dust and impurities from entering the interior and causing blockage, thereby affecting the subsequent entry of anhydrous hydrogen fluoride. When the stirring rod rotates, the driving component can drive the dustproof component as a whole to face each other, so that the outer end releases the blocking and sealing of the bottom of the liquid inlet pipe, thereby allowing the external pipe at the bottom of the liquid inlet pipe to smoothly transport liquid into the interior.

[0024] The present invention provides a liquid-passing component, a hydraulic component and a clamping component. When anhydrous hydrogen fluoride enters into the liquid inlet pipe, the liquid-passing component is pushed to open upward as a whole, so that the anhydrous hydrogen fluoride continues to move upward. At this time, negative pressure can be generated at the bottom of the hydraulic component to draw out the hydraulic oil in the clamping component, so that the dust-proof components are clamped and fixed by the top of the clamping component extending upward when facing each other, so that the dust-proof components are smoothly locked toward each other as a whole, so that the anhydrous hydrogen fluoride can always enter the liquid inlet pipe when being transported later, and the fixation can be released when no anhydrous hydrogen fluoride enters.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 9As shown, the present invention provides a fluorination reactor, comprising a reactor body 1; a stirring rod 2, which is arranged at the middle of the top of the reactor body 1 and penetrates the reactor body 1 at the bottom; a liquid inlet pipe 3, which is arranged on both sides of the bottom of the reactor body 1; an electric heating plate 10, which is arranged inside the outside of the reactor body 1; a one-way conveying component 4, which comprises a conveying pipe 401, the conveying pipe 401 is fixedly connected to the outside of the top of the liquid inlet pipe 3, the inside of the conveying pipe 401 is movably sleeved with a spiral conveying shaft 402, the top of the spiral conveying shaft 402 penetrates the conveying pipe 401, and the surface is fixedly sleeved with a first bevel gear 403, and the top of the liquid inlet pipe 3 is provided with a transmission component 5 located between the stirring rod 2 and the first bevel gear 403.

[0037] By operating the stirring rod 2, the transmission assembly 5 can drive the first bevel gear 403 and the screw conveying shaft 402 to rotate. At this time, the rotation of the screw conveying shaft 402 can unidirectionally convey the anhydrous hydrogen fluoride in the liquid inlet pipe 3 downward from the inside of the conveying pipe 401 to the inside of the solution through the screw conveying shaft 402.

[0038] like Figure 4 and Fig. 9 As shown, the transmission assembly 5 includes a driving gear 501, a sealing shell 502, a first driven gear 503, a second bevel gear 504 and a transmission connecting rod 505;

[0039] The driving gear 501 is fixedly sleeved on the surface of the stirring rod 2 and is located above the inner side of the liquid inlet pipe 3. The sealing shell 502 is fixedly installed on the top of the liquid inlet pipe 3. The first driven gear 503 is movably sleeved on the inner side of the sealing shell 502, and the first driven gear 503 and the driving gear 501 surface are meshed. The second bevel gear 504 is movably sleeved on the inside of the sealing shell 502 and is located on the inner side of the first bevel gear 403. The first driven gear 503 and the top of the second bevel gear 504 are connected through a transmission connecting rod 505.

[0040] By adopting the above solution: by providing a transmission connecting rod 505, when the stirring rod 2 rotates, it can drive the driving gear 501 to rotate and drive the first driven gear 503 to rotate as a whole, so that the rotation effect is transmitted to the second bevel gear 504 through the transmission connecting rod 505, so that the second bevel gear 504 rotates smoothly.

[0041] like Figure 4 As shown, the second bevel gear 504 and the surface of the first bevel gear 403 are meshed.

[0042] By adopting the above scheme: by providing the first bevel gear 403, when the second bevel gear 504 rotates, the teeth on the surface can drive the teeth on the surface of the first bevel gear 403 to drive the screw conveying shaft 402 to rotate as a whole, so as to transport the anhydrous hydrogen fluoride inside the liquid inlet pipe 3 to the solution through the inside of the conveying pipe 401 in one direction.

[0043] like Figure 2 , Figure 3 and Figure 6 As shown, a dustproof assembly 6 is provided on the inner side of the bottom of the liquid inlet pipe 3, and the dustproof assembly 6 includes a dustproof sealing plate 601, a sliding frame 602 and a first spring 603;

[0044] The dustproof sealing plate 601 is movably installed inside the bottom end of the liquid inlet pipe 3 , and the sliding frame 602 is fixedly installed on the inner side of the dustproof sealing plate 601 . The sliding frame 602 is elastically connected to the inner wall of the liquid inlet pipe 3 via a first spring 603 .

[0045] The above scheme is adopted: by providing a first spring 603, when the dustproof sealing plate 601 is driven toward each other as a whole, the first spring 603 can be compressed as a whole, and then the elastic force of the first spring 603 is released, which can push the sliding frame 602 and the dustproof sealing plate 601 to reset toward each other as a whole, so as to cover and seal the bottom of the liquid inlet pipe 3.

[0046] like Figure 5 and Figure 8 As shown, a driving assembly 7 is provided at the bottom of the reactor body 1 between the dustproof sealing plate 601 and the stirring rod 2, and the driving assembly 7 includes a rotating push plate 701, a second driven gear 702, a limiting frame 703, a movable frame 704 and a cam 705;

[0047] The rotating push plate 701 is movably sleeved on the bottom of the reactor body 1 and is located on the outside of the top of the sliding frame 602. The second driven gear 702 is fixedly sleeved on the top of the rotating push plate 701. The limiting frame 703 is fixedly installed on the top of the reactor body 1 and is located at one end of the inner side of the rotating push plate 701. The movable frame 704 is movably installed on the surface of the limiting frame 703. The cam 705 is fixedly sleeved on the middle part of the bottom end of the stirring rod 2.

[0048] By adopting the above solution, through the design of the limiting frame 703 , the movable frame 704 can slide toward or away from the surface of the limiting frame 703 , thereby achieving the limiting processing of the movement of the movable frame 704 .

[0049] like Figure 8 As shown, one side of the outer end of the movable frame 704 is meshed with the surface of the second driven gear 702 .

[0050] The above scheme is adopted: by providing a second driven gear 702, when the cam 705 rotates, the convex surface can push the two movable frames 704 to move in opposite directions. At this time, the teeth on one side of the outer end of the movable frame 704 will drive the teeth of the second driven gear 702, so that the second driven gear 702 and the rotating push plate 701 are driven to rotate, so that the rotating push plate 701 rotates to push the sliding frame 602 and then the dust sealing plate 601 as a whole moves towards each other.

[0051] like Figure 5 As shown, a liquid passing component 8 located above the dustproof component 6 is provided at the bottom of the inner cavity of the liquid inlet pipe 3, and the liquid passing component 8 includes a liquid passing pipe group 801, a liquid passing valve column 802, a one-way valve disc 803 and a second spring 804;

[0052] The liquid passage tube group 801 is fixedly installed at the bottom of the inner cavity of the liquid inlet pipeline 3, the liquid passage valve column 802 is movably installed in the inner cavity of the liquid inlet pipeline 3 and is located below the liquid passage tube group 801, the one-way valve flap 803 is arranged at the bottom of the inner cavity of the liquid passage valve column 802, and the top of the liquid passage valve column 802 is elastically connected to the bottom of the liquid passage tube group 801 through the second spring 804.

[0053] By adopting the above scheme, the elastic force of the second spring 804 can smoothly push the one-way valve flap 803 to move downward as a whole, so that the bottom of the liquid pipe group 801 is blocked and sealed, and then the anhydrous hydrogen fluoride at the bottom of the liquid valve column 802 can push the liquid valve column 802 upward as a whole, so that the bottom end of the liquid pipe group 801 pushes the one-way valve flap 803 to open, thereby releasing the blocking and sealing of the bottom of the liquid pipe group 801.

[0054] like Figure 5 As shown, a hydraulic assembly 9 located inside the liquid inlet pipe 3 and located inside the liquid valve column 802 is provided. The hydraulic assembly 9 includes a first hydraulic cylinder 901, a hydraulic piston rod 902 and a connecting block 903;

[0055] The first hydraulic cylinder 901 is fixedly installed inside the liquid inlet pipe 3 and is located below the inner side of the liquid valve column 802. The hydraulic piston rod 902 is movably installed in the inner cavity of the first hydraulic cylinder 901. The connecting block 903 is fixedly installed on the top of the hydraulic piston rod 902. The outer side of the connecting block 903 is fixedly connected to the inner side of the liquid valve column 802.

[0056] By adopting the above solution, by providing a connecting block 903, when the entire liquid pipe group 801 is pushed upward by anhydrous hydrogen fluoride, the entire hydraulic piston rod 902 can be driven upward synchronously through the connecting block 903, so that negative pressure is generated at the bottom of the inner cavity of the first hydraulic cylinder 901.

[0057] like Figure 6As shown, a clamping assembly 11 located inside the first spring 603 is provided inside the liquid inlet pipe 3, and the clamping assembly 11 includes a second hydraulic cylinder 1101, a clamping piston rod 1102, a rectangular clamping groove 1103 and an oil pipeline 1104;

[0058] The second hydraulic cylinder 1101 is fixedly installed inside the liquid inlet pipe 3 and is located on the inner side of the first spring 603. The clamping piston rod 1102 is movably installed inside the second hydraulic cylinder 1101. The rectangular slot 1103 is opened at the inner bottom of the sliding frame 602. The second hydraulic cylinder 1101 is fixedly connected to the bottom end of the first hydraulic cylinder 901 through the oil pipeline 1104.

[0059] The above scheme is adopted: by providing an oil pipeline 1104, when negative pressure is generated at the bottom of the first hydraulic cylinder 901, the hydraulic oil at the top of the inner cavity of the second hydraulic cylinder 1101 can be pumped away through the oil pipeline 1104, so that the entire clamping piston rod 1102 can be moved upward by the negative pressure.

[0060] like Figure 6 As shown, the size of the top end of the clamping piston rod 1102 matches the size of the inner wall of the rectangular clamping groove 1103 .

[0061] The above scheme is adopted: by providing a rectangular slot 1103, when the dustproof sealing plate 601 and the sliding frame 602 are facing each other as a whole, the rectangular slot 1103 will be opposite to the top end of the clamping piston rod 1102. At this time, by clamping the piston rod 1102 upward, the top end can be completely inserted into the rectangular slot 1103, so as to clamp and fix the dustproof sealing plate 601 and the sliding frame 602 facing each other.

[0062] The working principle and use process of the present invention:

[0063] First, the operator can put the corresponding solution into the reactor body 1, and then start the stirring rod 2 to rotate for pre-stirring. At this time, the cam 705 can be driven to rotate, so that the protruding part pushes the movable frame 704 to move in opposite directions, so that the outer end tooth surface of the movable frame 704 can drive the rotating push plate 701 and the second driven gear 702 to rotate as a whole, so that the rotating push plate 701 deflects and pushes the sliding frame 602 and the dustproof sealing plate 601 to move towards each other as a whole, so that the dustproof sealing plate 601 can release the blocking seal on the bottom of the liquid inlet pipe 3 towards each other, and then an external pipe can be connected to smoothly introduce anhydrous hydrogen fluoride into the interior of the liquid inlet pipe 3.

[0064] After that, when anhydrous hydrogen fluoride is continuously introduced into the interior of the liquid inlet pipe 3, the anhydrous hydrogen fluoride can push the entirety of the liquid-passing valve column 802 upward, so that the one-way valve flap 803 at the bottom top of the liquid-passing pipe group 801 is turned downward, so that the anhydrous hydrogen fluoride can be smoothly transported upward through the interior of the liquid-passing pipe group 801. At this time, the liquid-passing valve column 802 is moved upward, so that the entirety of the connecting block 903 and the hydraulic piston rod 902 can be simultaneously driven upward, so that the bottom of the inner cavity of the first hydraulic cylinder 901 is generated. Negative pressure can then be used to draw away the hydraulic oil at the top of the inner cavity of the second hydraulic cylinder 1101 through the oil pipeline 1104, so that the clamping piston rod 1102 is driven upward as a whole. When the dustproof sealing plate 601 and the sliding frame 602 move toward each other to the innermost side as a whole, the top of the clamping piston rod 1102 can be opposite to the rectangular slot 1103. At this time, the top end of the clamping piston rod 1102 can be inserted upward into the rectangular slot 1103, so that the dustproof sealing plate 601 is clamped and fixed as a whole.

[0065] Subsequently, the anhydrous hydrogen fluoride can smoothly enter the interior of the liquid inlet pipe 3, and when the stirring rod 2 rotates again, the driving gear 501 can be rotated synchronously. At this time, due to the meshing relationship between the surfaces of the driving gear 501 and the first driven gear 503, the first driven gear 503 can be driven to rotate, and then the second bevel gear 504 can be linked to rotate as a whole through the transmission connecting rod 505, and the meshing relationship between the second bevel gear 504 and the first bevel gear 403 can drive the first bevel gear 403 and the screw conveying shaft 402 to rotate as a whole, and then due to the rotation of the screw conveying shaft 402, the anhydrous hydrogen fluoride inside the liquid inlet pipe 3 can be unidirectionally transported from the bottom of the conveying pipe 401 to the solution, and finally the interior is heated by the operation of the electric heating plate 10, and the anhydrous hydrogen fluoride and the solution can be mixed and stirred by the rotation of the stirring rod 2.
