Description

Technical Field

[0001] The utility model relates to the technical field of tubular reactors, in particular to a tubular reactor used for synthesizing electronic-grade chemicals. Background Art

[0002] A tubular reactor is a continuously operated reactor with a large aspect ratio and is a plug flow reactor. This type of reactor can be designed to be very long, such as the tube length of reactors for propylene dimerization or polyethylene, which can even be measured in kilometers. The structure of a tubular reactor is flexible, and can be a single tube or multiple tubes in parallel. It can be an empty tube for reactions such as tubular cracking furnaces, or a filled tube with granular catalysts for multiphase catalytic reactions, such as tubular fixed bed reactors.

[0003] In the synthesis of electronic-grade chemicals, there are many types of reactions, including reactions between solids and liquids. For example, in the electronics industry, some metal salts such as cadmium chloride, zinc chloride, etc. may also be synthesized by reactions between solids and liquids; for example, a metal oxide (solid) is dissolved in the corresponding acid (liquid), and the desired metal salt is prepared by double decomposition or acid-base reaction.

[0004] Chinese patent announcement number CN216024794U discloses a tubular reactor, including: a front-end structure, a heat exchanger, a support, a rear-end structure, a partition, a tie rod, a buffer structure and an inspection structure.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 and Figure 2 As shown, a tubular reactor for synthesizing electronic-grade chemicals comprises a reaction tube 2, a connecting flange 1 is fixedly connected to the left side of the reaction tube 2, a stirring assembly 3 is arranged in the inner cavity of the reaction tube 2, a connecting pipe 4 is fixedly connected to the right part of the outer surface of the reaction tube 2, a ball valve 5 is fixedly connected to the upper end of the connecting pipe 4, a circular shell 7 is fixedly connected to the upper port of the ball valve 5, a water inlet pipe 6 is fixedly connected to the left side of the outer surface of the circular shell 7, and a rolling assembly 8 is arranged on the inner surface of the circular shell 7.

[0028] The above-mentioned ball valve 5 is composed of a valve body, a ball, a valve seat, a valve stem, an operating mechanism, a sealing ring, and other auxiliary components. It is a mature technical means in the prior art. This scheme only uses it to realize the opening, closing and sealing functions of the valve. Its structure and working principle will not be further elaborated here.

[0029] In a specific implementation, the device is fixedly connected to other components for obtaining the synthetic substance after the reaction of the device through the connecting flange 1, and the sealing of the reaction tube 2 after the fixed connection must be ensured;

[0030] Open the ball valve 5, put the solid material that needs to participate in the synthesis reaction of electronic-grade chemicals into the rolling assembly 8, turn on the stirring assembly 3 to drive the rolling assembly 8 to operate, and the rolling assembly 8 crushes the solid material participating in the reaction, and enters the connecting pipe 4 through the opened ball valve 5, and further falls into the reaction tube 2;

[0031] The liquid substance involved in the synthesis of electronic-grade chemicals is transported to the circular shell 7 through the water inlet pipe 6, and enters the reaction tube 2 through the opened ball valve 5, and then the ball valve 5 is closed, and the stirring component 3 is turned on to operate. At this time, the crushing component 8 is not operated. The stirring component 3 is operated to stir the crushed solid substance and liquid substance entering the reaction tube 2, so that the solid substance and the liquid substance can be fully fused.

[0032] Specifically, in order to increase the contact area between the solid substance and the liquid substance involved in the reaction, so that the solid substance can be better dissolved in the liquid substance, refer to Figure 4 The rolling assembly 8 includes a filter plate 84 and a circular baffle 85. The filter plate 84 is fixedly connected to the lower side of the inner surface of the circular shell 7. A circular groove 83 is provided on the lower side of the inner surface of the circular shell 7. The circular baffle 85 is rotatably connected to the upper side of the inner surface of the circular groove 83. A rotating assembly 82 is provided at the middle of the upper end of the filter plate 84. A driven assembly 81 is provided on the right side of the rotating assembly 82.

[0033] Further reading Figure 5 The driven component 81 includes a pulley 812, which is fixedly connected to the right side of the outer surface of the rotating rod 33. The upper left end of the vertical part of the L-shaped plate 31 is rotatably connected to a round rod 813, and the outer surface of the round rod 813 is fixedly connected to a one-way bearing 811. The pulley 812 is fixedly connected to the outer surface of the one-way bearing 811. The left end of the round rod 813 penetrates the outer surface of the circular housing 7 and extends into the circular housing 7. The left side of the outer surface of the round rod 813 is fixedly connected to a bevel gear 814; the pulley 812 includes a belt and two rotating wheels in contact with the belt.

[0034] Further reading Figure 6The rotating assembly 82 includes a second round rod 822, which is rotatably connected to the middle part of the upper end of the filter plate 84, and a second bevel gear 821 is fixedly connected to the upper side of the outer surface of the second round rod 822, and the second bevel gear 821 is meshed with the first bevel gear 814, and a round roller assembly 823 is arranged on the lower side of the outer surface of the second round rod 822; the round roller assembly 823 includes a fixed ring 8231, which is fixedly connected to the lower side of the outer surface of the second round rod 822, and the outer surface of the fixed ring 8231 is rotatably connected to the connecting Rod 8233, one end of the connecting rod 8233 away from the fixed ring 8231 passes through the inner surface of the circular baffle 85 and extends to the outside of the circular baffle 85, the connecting rod 8233 is rotatably connected to the circular baffle 85, a circular roller 8232 is fixedly connected to the outer surface of the connecting rod 8233, one end of the connecting rod 8233 away from the fixed ring 8231 is fixedly connected to a bevel gear 8234, and a bevel gear ring 8235 is fixedly connected to the lower side of the inner surface of the circular groove 83, and the bevel gear 8234 is meshed with the bevel gear ring 8235.

[0035] The one-way bearing 811 mentioned above is a special type of bearing, and its main feature is that it allows axial movement to be transmitted in only one direction, while locking or preventing rotation in the other direction. It is a mature technical means in the prior art, and this solution will not further elaborate on its structure and working principle;

[0036] In a specific implementation, the solid matter involved in the synthesis reaction of electronic-grade chemicals is placed in the circular housing 7. Since the holes opened on the filter plate 84 are smaller than the volume of the solid matter, the solid matter is blocked by the filter plate 84 and cannot enter the reaction tube 2.

[0037] The stirring assembly 3 is turned on. Under the action of the pulley 812 and the one-way bearing 811, the round rod 1 813 is driven to rotate, thereby driving the bevel gear 1 814 to rotate. Since the bevel gear 1 814 is meshed with the bevel gear 2 821, the rotation of the bevel gear 2 821 drives the round rod 2 822 to rotate, thereby driving the fixed ring 8231 to rotate, so that the round roller 8232 revolves to grind the solid matter on the filter plate 84 and grind the solid matter into powder, thereby increasing the contact area between the solid matter and the liquid matter when the subsequent solid matter and the liquid matter react in the reaction tube 2, so that the solid matter can be more quickly fused with the liquid matter;

[0038] When the round roller 8232 revolves, the bevel gear 8234 is always meshed with the bevel gear ring 8235 and rotates in a circle, thereby driving the connecting rod 8233 to rotate, so that the round roller 8232 can rotate while revolving, thereby further improving the efficiency of the round roller 8232 in crushing solid materials;

[0039] After the solid matter is crushed, the water inlet pipe 6 is fixedly connected to the pipe for conveying liquid matter, and the liquid matter is conveyed into the circular shell 7 through the water inlet pipe 6. The outlet position of the water inlet pipe 6 is above the filter plate 84. The liquid matter coming out of the water inlet pipe 6 can flush the solid matter powder remaining on the filter plate 84 to prevent the solid powder from remaining on the filter plate 84 and causing waste of solid matter.

[0040] Specifically, in order to allow the solid matter and the liquid matter in the reaction tube 2 to be fully integrated, thereby improving the quality of the synthetic substance produced after the reaction, refer to Figure 3 The stirring assembly 3 includes an L-shaped plate 31, which is fixedly connected to the right end of the reaction tube 2. A motor 32 is fixedly connected to the upper end of the horizontal part of the L-shaped plate 31. A rotating rod 33 is fixedly connected to the output end of the motor 32 through a coupling. The left end of the rotating rod 33 passes through the middle of the right end of the reaction tube 2 and extends into the reaction tube 2. A spiral blade 34 is fixedly connected to the outer surface of the rotating rod 33. The spiral blade 34 is rotatably connected to the inner surface of the reaction tube 2; several blade parts of the spiral blade 34 are distributed in a linear array.

[0041] The motor 32 is a servo motor, which is a mature technical means in the prior art. This solution only uses its functions of realizing forward and reverse rotation, controlling the rotation speed and number of rotations of an object, and starting and stopping at any time. Its structure and working principle will not be further elaborated here.

[0042] In the specific implementation, the motor 32 is turned on to drive the rotating rod 33 to rotate forward. Under the action of the pulley 812 and the one-way bearing 811, the round rod 813 can be driven to rotate. The motor 32 is turned on to drive the rotating rod 33 to rotate reversely. Under the action of the one-way bearing 811, the rotation of the rotating rod 33 cannot drive the round rod 813 to rotate. At this time, the rolling component 8 does not operate, so there is no need for the rolling component 8 to roll the solid material. Only when the stirring component 3 is running, the rolling component 8 does not need to operate, which can save energy and thus save the cost of synthesizing and producing electronic-grade chemicals.

[0043] After the crushed solid and liquid substances have entered the reaction tube 2, the ball valve 5 is closed, and then the motor 32 is turned on to drive the rotating rod 33 to reverse, thereby driving the spiral blade 34 to rotate, and the solid and liquid substances in the reaction tube 2 are stirred, so that the solid and liquid substances can be fully integrated, thereby improving the quality of the synthetic substance produced after the solid and liquid substances react in the reaction tube 2.

[0044] It should be noted that the specific installation method of the motor 32, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0045] The working principle of the utility model is:

[0046] Open the ball valve 5, put the solid material into the circular housing 7, turn on the motor 32 to drive the rotating rod 33 to rotate forward, and under the action of the pulley 812 and the one-way bearing 811, the round rod 1 813 is driven to rotate, and under the meshing action of the bevel gear 1 814 and the bevel gear 2 821, the round rod 2 822 is rotated, thereby driving the fixed ring 8231 to rotate, so that the round roller 8232 revolves to crush the solid material on the filter plate 84 and crush the solid material into powder;

[0047] After the solid material is crushed, the water inlet pipe 6 is fixedly connected to the pipe for conveying the liquid material, and the liquid material is conveyed into the circular housing 7 through the water inlet pipe 6;

[0048] The ball valve 5 is closed, and then the motor 32 is turned on to drive the rotating rod 33 to reverse, thereby driving the plurality of spiral blades 34 to rotate, so as to stir the solid and liquid substances in the reaction tube 2 so that the solid and liquid substances can be fully integrated.

[0049] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
