Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a reactor using ultrasonic stirring. Background Art

[0002] A reactor is a container used for physical or chemical reactions. It is widely used in the fields of petroleum, chemical industry, rubber, pesticide, medicine and food. It is usually used to complete processes such as sulfidation, nitration and hydrogenation.

[0003] Ultrasonic waves also play an important role in chemical synthesis. Nowadays, ultrasonic mechanisms are added to reactors. The ultrasonic waves generated by ultrasonic piezoelectric transducers come into contact with the reaction medium, producing ultrasonic cavitation. The small bubbles formed by ultrasonic cavitation will vibrate, expand or burst around the medium. When the bubbles burst, the surrounding medium quickly rushes into the bubbles, generating high temperature, high pressure, and shock waves, which can promote emulsification, liquefaction, and dispersion of solids, thereby accelerating the reaction efficiency and reaction effect of the medium.

[0004] However, in the existing ultrasonic reactors, most of them are provided with an ultrasonic piezoelectric transducer inside the reactor, and ultrasonic piezoelectric transducer outputs ultrasonic waves to the medium, and mechanical stirring is used to make the reaction medium flow in the reactor, so as to promote continuous and sufficient contact between the reaction medium and the ultrasonic piezoelectric transducer, thereby achieving the effect of comprehensive ultrasonic treatment of the reaction medium.

[0005] However, for the traditional mechanical stirring method, if a large amount of reaction medium flows in the reactor, it takes a certain amount of time to fully ultrasonically treat the reaction medium, resulting in the problem of low efficiency of ultrasonic treatment. In addition, when the ultrasonic wave generated by the ultrasonic piezoelectric transducer acts on the reaction medium, the uniformity of ultrasonic treatment of the reaction medium cannot be guaranteed. Often, the closer the reaction medium is to the ultrasonic piezoelectric transducer, the more bubbles it contains, while the reaction medium at a farther distance contains fewer bubbles, resulting in the uniformity of ultrasonic treatment cannot be guaranteed, which not only prolongs the time of ultrasonic treatment, but also fails to guarantee the uniformity of ultrasonic treatment. Summary of the invention

[0006] The object of the present invention is to provide a reaction kettle using ultrasonic stirring to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a reaction kettle using ultrasonic stirring, comprising a kettle body, a plurality of positioning rods and a turntable;

[0008] An inner cylinder is arranged inside the kettle body, a compartment is formed between the inner wall of the kettle body and the outer wall of the inner cylinder body, and a uniformly distributed liquid groove is opened on the bottom surface of the inner cylinder body;

[0010] Preferably, the kettle body further comprises a plurality of first ultrasonic piezoelectric transducers, a drive motor and a stirring shaft;

[0011] The plurality of the first ultrasonic piezoelectric transducers are evenly distributed at the bottom of the kettle body, the output end of the driving motor is connected to the stirring shaft, and the surface of the stirring shaft is provided with evenly distributed paddles.

[0014] Preferably, one end of the plurality of positioning rods facing away from the turntable is connected to a limiting ring, and the limiting ring is slidably installed in the inner wall of the bottom end of the kettle body.

[0015] Preferably, each of the shredding pieces further comprises a rotating shaft, which is arranged inside the shredding piece, and each of the rotating shafts is rotatably mounted inside the positioning rod;

[0016] The turntable further comprises a plurality of lifting mechanisms, each of which comprises a servo motor and a threaded sleeve, and the output end of each servo motor is connected to the top end of the threaded sleeve;

[0017] Each of the positioning rods also includes a synchronization rod, and each of the synchronization rods is slidably installed inside the positioning rod.

[0018] Preferably, the top outer wall of each synchronization rod is meshed with the inner wall of the threaded sleeve.

[0021] Preferably, the surface of the turntable is provided with evenly distributed limiting holes, and the upper end of each of the synchronization rods passes through the limiting hole.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention achieves the effect of improving the comprehensiveness of ultrasonic treatment of reaction medium by arranging partitions and twisted pieces. The positioning rod drives the twisted pieces to rotate in the partitions, and the twisted pieces also divide the partitions into multiple levels, which can not only drive the reaction medium in the partitions to flow upward, but also perform ultrasonic treatment on the reaction medium above the twisted pieces through the second ultrasonic piezoelectric transducer; the spacing of the twisted pieces can control the flow of reaction medium within the optimal treatment range of the second ultrasonic piezoelectric transducer, ensuring that the reaction medium can be subjected to uniform, comprehensive and rapid ultrasonic treatment when flowing over the second ultrasonic piezoelectric transducer.

[0024] 2. The present invention achieves the effect of flexibly adjusting the angle of the slice by setting a synchronization rod and a lifting mechanism. The staff can drive the synchronization rod to move through the lifting mechanism according to actual usage, and then drive the slice to deflect along the rotating shaft, so as to adjust the angle between the slice and the horizontal plane. In conjunction with the rotation of the slice in the compartment, the speed of the reaction medium flowing upward in the compartment can be flexibly adjusted, thereby improving the flexibility and controllability of practical applications.

[0038] 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.

[0039] See also Figures 1 to 8 , the present invention provides the following two embodiments:

[0040] Embodiment 1:

[0041] See also Figures 1 to 3 A reaction kettle using ultrasonic stirring includes a kettle body 100, a plurality of positioning rods 200 and a turntable 300.

[0042] See also Figure 2 and Figure 3 The kettle body 100 further includes a plurality of first ultrasonic piezoelectric transducers 120, a driving motor 140 and a stirring shaft 150. The output end of the driving motor 140 is connected to the stirring shaft 150, the outer wall of the stirring shaft 150 is connected to the inner wall of the rotating disk 300, and the driving motor 140 drives the stirring shaft 150 and the rotating disk 300 to rotate respectively, thereby driving the positioning rod 200 and the paddle 151 to rotate.

[0043] See also Figure 1 and Figure 2, a plurality of first ultrasonic piezoelectric transducers 120 are evenly distributed at the bottom of the kettle body 100, and the first ultrasonic piezoelectric transducers 120 are used to perform ultrasonic pretreatment on the reaction medium in the kettle body 100, thereby generating a certain amount of bubbles in the reaction medium, so as to achieve a better treatment effect in the secondary ultrasonic treatment. Secondly, during the cleaning process of the inside of the kettle body 100, the bubbles generated by the first ultrasonic piezoelectric transducer 120 can contact the inner wall of the stirring shaft 150 and the inner cylinder 110, thereby achieving the effect of internal cleaning and reducing the difficulty of manual cleaning.

[0044] See also Figures 1 to 3 The surface of the stirring shaft 150 is provided with evenly distributed paddles 151, and the deflection direction of each paddle 151 is opposite to the deflection direction of each slice 210. During the rotation process, the paddle 151 generates a downward flow of the reaction medium, so that the reaction medium flow continuously contacts the processing area of ​​the first ultrasonic piezoelectric transducer 120, which not only plays a role in mixing and stirring the reaction medium, but also plays a role in controlling the convective flow of the reaction medium in the kettle body 100 and the compartment 130, thereby achieving the effect of circulating the reaction medium.

[0045] See also Figure 1 and Figure 2 An inner cylinder 110 is arranged inside the kettle body 100, and a partition 130 is formed between the inner wall of the kettle body 100 and the outer wall of the inner cylinder 110. The inner cylinder 110 divides the internal space of the kettle body 100. The formed partition 130 and the internal space of the kettle body 100 have an independent space, which is conducive to ultrasonic treatment of the reaction medium.

[0046] See also Figure 1 and Figure 2 The bottom surface of the inner cylinder 110 is provided with evenly distributed liquid grooves 111, and the paddles 151 rotate to generate a reaction medium flow flowing downward, and the reaction medium flow flows through the action area of ​​the first ultrasonic piezoelectric transducer 120, and then flows into the compartment 130 through the liquid grooves 111, and the reaction medium flow flows upward along the inside of the compartment 130. The reaction medium flowing upward in the compartment 130 flows into the kettle body 100 again when passing through the top opening of the compartment 130, forming a convection circulation of the reaction medium.

[0047] See also Figures 1 to 3 A plurality of positioning rods 200 are evenly arranged inside the compartment 130, and the plurality of positioning rods 200 are evenly connected to the surface of the turntable 300. A plurality of tangent plates 210 are arranged on the surface of each positioning rod 200, and a second ultrasonic piezoelectric transducer 211 is arranged on the surface of each tangent plate 210.

[0048] During the rotation of the positioning rod 200 along the interior of the partition 130, the twisted pieces 210 on the surface of the positioning rod 200 rotate along the internal space of the partition 130. During the rotation of the inclined twisted pieces 210 inside the partition 130, the reaction medium flow is separated and the reaction medium flow is pushed to move upward along the partition 130. In addition, multiple twisted pieces 210 separate the space of the partition 130 where the positioning rod 200 is located, thereby reducing the processing area above the second ultrasonic piezoelectric transducer 211, so that the space above the second ultrasonic piezoelectric transducer 211 is the optimal range for ultrasonic processing.

[0049] When the reaction medium passes through the space above the slice 210, the second ultrasonic piezoelectric transducer 211 performs sufficient and uniform ultrasonic treatment on the flowing reaction medium, which not only improves the ultrasonic treatment speed of the reaction medium, but also improves the uniform distribution of the bubbles generated by the ultrasonic wave in the reaction medium. When the bubbles generated by the ultrasonic wave break in the reaction medium, the surrounding reaction medium quickly rushes into the bubbles, generating high temperature, high pressure, and shock waves, thereby promoting emulsification, liquefaction and dispersion of solids, thereby accelerating the reaction efficiency and reaction effect of the medium.

[0050] The first ultrasonic piezoelectric transducer 120 and the second ultrasonic piezoelectric transducer 211 both use X4C3840 ultrasonic piezoelectric transducers, which undergo power conversion through an ultrasonic generator power module to form the resonant wave band required by the piezoelectric transducer, which is then output to the piezoelectric transducer to generate ultrasonic waves.

[0051] The power supply circuit of the second ultrasonic piezoelectric transducer 211 is respectively embedded and installed inside the scissor 210 and the rotating shaft 212, and goes up from the hollow area in the positioning rod 200 to the surface of the turntable 300. An electric ring is set on the surface of the stirring shaft 150, and the external power supply circuit is connected to the brush. The brush is in sliding contact with the electric ring on the surface of the stirring shaft 150 to provide power for the second ultrasonic piezoelectric transducer 211, and the external power supply circuit is connected to the power module of the ultrasonic generator, and the power module converts the electric energy into a high-frequency AC signal that matches the ultrasonic piezoelectric transducer. The ultrasonic piezoelectric transducer uses the piezoelectric ceramic vibrator as the core component and can convert electrical energy into mechanical energy. When an alternating voltage is applied to the piezoelectric ceramic, an alternating strain is generated, thereby realizing the conversion of electrical energy to mechanical energy, and then generating ultrasonic waves to act on the reaction medium.

[0052] See also Figure 3 The ends of the multiple positioning rods 200 facing away from the turntable 300 are connected to the limiting ring 230, and the limiting ring 230 is slidably installed in the inner wall of the bottom end of the kettle body 100. The limiting ring 230 limits the bottom end of the positioning rod 200, keeps the positioning rod 200 rotating in the compartment 130, and ensures the normal operation of the shredder 210.

[0053] Embodiment 2:

[0054] See also Figures 4 to 8 Based on the above-mentioned invention, the present invention also provides another embodiment:

[0055] See also Figures 4 to 7 Each shroud 210 further includes a rotating shaft 212, which is disposed inside the shroud 210, and each of the rotating shafts 212 is rotatably mounted inside the positioning rod 200. The surface of the turntable 300 is provided with evenly distributed limiting holes, and the upper end of each synchronization rod 220 passes through the limiting hole. The limiting hole is used to limit the synchronization rod 220 from rotating, so that the synchronization rod 220 can only rise and fall, thereby ensuring that the lifting and lowering of the synchronization rod 220 drives the shroud 210 to deflect along the rotating shaft 212.

[0056] See also Figure 4 , Figure 6 and Figure 8 The turntable 300 further includes a plurality of lifting mechanisms 400 , each of which includes a servo motor 410 and a threaded sleeve 420 , and an output end of each servo motor 410 is connected to a top end of the threaded sleeve 420 .

[0057] Please refer to the figure Figure 6 Each positioning rod 200 also includes a synchronization rod 220, and each synchronization rod 220 is slidably installed inside the positioning rod 200. The top outer wall of each synchronization rod 220 is meshed with the inner wall of the threaded sleeve 420. After the servo motor 410 drives the threaded sleeve 420 to rotate, the thread on the inner wall of the threaded sleeve 420 rotates and meshes with the thread between the outer wall of the synchronization rod 220, thereby driving the synchronization rod 220 to move in a vertical direction. The synchronization rod 220 drives multiple twisted pieces 210 on the surface of the corresponding positioning rod 200 to deflect.

[0058] See also Figure 6 and Figure 7 , a plurality of tooth grooves 221 are formed on the surface of each synchronization rod 220, and the surface of each rotating shaft 212 is meshed with the tooth grooves 221. After the synchronization rod 220 is raised or lowered, the tooth grooves 221 on the surface of the synchronization rod 220 move relative to the surfaces of the plurality of rotating shafts 212 synchronously, and the tooth grooves 221 mesh with the racks on the surface of the rotating shaft 212, so that the vertical displacement of the tooth grooves 221 is converted into the circular motion of the rotating shaft 212, thereby driving the shroud 210 to rotate along the rotating shaft 212, so that the shroud 210 is deflected in the compartment 130.

[0059] When the slicing blade 210 is deflected, the slicing blade 210 rotates in the compartment 130, and the longitudinal contact surface between the slicing blade 210 and the reaction medium flow can be adjusted, so that the speed of the slicing blade 210 conveying the reaction medium to the space above the compartment 130 can be adjusted, and the speed of the reaction medium flowing through the space above the second ultrasonic piezoelectric transducer 211 can be adjusted, so as to achieve the effect of controlling the ultrasonic treatment speed. Secondly, the speed of the reaction medium flowing back from the upper end space of the compartment 130 to the internal space of the kettle body 100 can also be adjusted, so that the staff can make flexible adjustments according to the actual production situation.

[0060] In addition, multiple lifting mechanisms 400 can be controlled independently and synchronously, so that the deflection angles of the twisted pieces 210 on the surfaces of multiple positioning rods 200 can be adjusted to be consistent, or the deflection angles of the twisted pieces 210 on the surfaces of one or more positioning rods 200 can be adjusted independently, thereby achieving the effect of mixing the reaction medium and improving the flexibility and controllability of practical applications.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
