Description

Technical Field

[0001] The utility model relates to the technical field of ribbon stirring equipment, and particularly relates to a ribbon stirring reactor capable of measuring temperature. Background Art

[0002] A ribbon stirring reactor is a device that combines the functions of a ribbon stirrer and a reactor, and is mainly used for mixing and stirring materials during a chemical reaction process. When the stirring shaft rotates, the spiral stirring paddle pulls the materials from the bottom or side of the reactor towards the axis, and then pushes them out along the axis direction. During this process, the materials are fully mixed and stirred, promoting the progress of the chemical reaction.

[0003] In order to improve the stirring quality, the length of the stirring paddle is usually set to be slightly less than the radius of the reactor. During the rotation of the stirring paddle, there is a very small gap between the end of the stirring paddle and the inner wall of the reactor. If a temperature monitor is bound to the stirring paddle, since the stirring paddle rotates, the wire of the thermometer will rotate accordingly, resulting in wire entanglement. Therefore, a thermal resistor or other temperature monitors cannot be inserted into a conventional ribbon stirring reactor. This leads to the inability to accurately measure the temperature of the materials inside the reactor equipped with a ribbon stirring paddle, thereby increasing the difficulty of the stirring operation, and the reaction temperature of the materials inside the reactor is not controlled, posing a great potential safety hazard.

[0004] Therefore, the prior art needs to be further developed. Summary of the Utility Model

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

[0029] According to an embodiment of the present invention, a ribbon-type stirring reaction kettle capable of measuring temperature is provided. Please refer to Figures 1 to 6 , including: a kettle body 1, an installation port 11 is provided at the top of the kettle body 1; a stirring assembly 2, the stirring assembly 2 includes a driving motor 21, a stirring shaft 22 and a plurality of stirring blades 23, each of the stirring blades 23 is a ribbon-type blade, the stirring shaft 22 passes through the installation port 11 and enters the kettle body 1 and is connected to each of the stirring blades 23, the driving motor 21 drives the stirring shaft 22 to rotate, so that each of the stirring blades 23 rotates and stirs; a temperature measuring assembly 3, the temperature measuring assembly 3 includes a conductive slip ring 31 and a temperature sensor 32, the conductive slip ring 31 is connected to the stirring shaft 22, the conductive slip ring 31 is used to maintain electrical connection when the stirring shaft 22 rotates, the wire 311 of the conductive slip ring 31 extends into the kettle body 1 and is electrically connected to the temperature sensor 32, the temperature sensor 32 is used to measure the temperature of the material in the kettle and is signal-connected to the controller of the reaction kettle to transmit temperature data; a sealing assembly 4, the sealing assembly 4 is arranged around the stirring shaft 22, and the sealing assembly 4 is arranged corresponding to the installation port 11 to keep the kettle body 1 sealed when the stirring shaft 22 rotates. Connect the rotor end of the conductive slip ring 31 to the stirring shaft 22, and the wire 311 extends into the kettle body 1 and is electrically connected to the temperature sensor 32, so as to realize real-time monitoring of the temperature of the material in the kettle and accurately transmit the data to the controller of the reaction kettle. This real-time temperature monitoring function enables the operator to adjust the process parameters in time to ensure that the reaction is carried out under the optimal temperature conditions, thereby improving the product quality and production efficiency. With such a design, the problem in the prior art that there is a very small gap between the end of the stirring paddle and the inner wall of the kettle and a temperature monitor cannot be installed, and the operator cannot accurately know the temperature inside the kettle is solved. The ribbon-type stirring reaction kettle capable of measuring temperature in this embodiment solves the technical problem that it is difficult to control the temperature of the material in the ribbon-type stirring reaction kettle in the related art.

[0030] Please refer to Figure 1 , in the ribbon-type stirring reaction kettle capable of measuring temperature in this embodiment, the conductive slip ring 31 is fixed on the installation port 11, and when the stirring shaft 22 rotates, the rotor of the conductive slip ring 31 rotates accordingly. Since the rotor of the conductive slip ring 31 rotates synchronously with the stirring shaft 22, this design ensures the continuous transmission of electrical signals during the rotation process and will not be interrupted due to the rotation of the stirring shaft.

[0031] Please refer toFigure 1 , for the ribbon-type stirring reactor capable of measuring temperature in this embodiment, the stirring shaft 22 is of a hollow structure. The wire 311 extends into the inner cavity of the stirring shaft 22, and the temperature sensor 32 is fixed on the stirring shaft 22. The end of the wire 311 penetrates through the stirring shaft 22 and is connected to the temperature sensor 32. The design of the hollow stirring shaft 22 provides a safe passage for the wire 311, avoiding the direct exposure of the wire to the high temperature, high pressure or corrosive environment inside the reactor, thereby reducing the risk of wire damage and improving the safety and reliability of the equipment.

[0032] Refer to Figure 2 and Figure 3 , for the ribbon-type stirring reactor capable of measuring temperature in this embodiment, the sealing assembly 4 includes a sealing ring 41. The stirring shaft 22 is rotatably arranged relative to the sealing ring 41. The stirring shaft 22 passes through the sealing ring 41 and jointly seals the installation opening 11 with the sealing ring 41. The design of the sealing ring 41 enables the stirring shaft 22 to maintain close contact with the sealing ring during rotation without causing seal failure.

[0033] Refer to Figure 2 , for the ribbon-type stirring reactor capable of measuring temperature in this embodiment, the sealing assembly 4 further includes an elastic snap ring 42. The elastic snap ring 42 is embedded in the sealing ring 41. By pressing the sealing ring 41, the elastic snap ring 42 located inside the sealing ring 41 is deformed under force, so that the stirring shaft 22 sleeved with the sealing ring 41 is installed on the installation opening 11. After the external force disappears, the elastic snap ring 42 resets, so that the sealing ring 41 is tightly pressed on the installation opening 11. The elastic snap ring 42 is embedded in the sealing ring 41. By pressing the sealing ring 41, the elastic snap ring 42 is deformed under force, and then the stirring shaft 22 sleeved with the sealing ring 41 is firmly installed on the installation opening 11. When the external force disappears, the elastic snap ring 42 automatically resets, making the sealing ring 41 more tightly pressed on the installation opening 11, thereby enhancing the overall sealing effect.

[0034] For the ribbon-type stirring reactor capable of measuring temperature in this embodiment, the elastic snap ring 42 is made of a metal material. The metal material has high strength and hardness, can withstand the force and vibration generated during the rotation of the stirring shaft 22, ensures that the elastic snap ring 42 is not easily deformed or damaged during long-term use, and at the same time has good elastic recovery ability and can quickly return to its original shape after being deformed under force; the sealing ring 41 is made of a corrosion-resistant material. The corrosion-resistant material can resist the erosion of chemical media, extending the service life of the sealing ring 41.

[0035] Refer to Figure 2 and Figure 3, for the temperature-measurable spiral ribbon stirring reactor of this embodiment, a ring groove 111 is provided on the mounting port 11, and a ring-shaped protrusion 411 is provided on the outer periphery of the sealing ring 41. When the sealing ring 41 seals the mounting port 11, the ring-shaped protrusion 411 is stuck in the ring groove 111. The cooperation between the ring-shaped protrusion 411 and the ring groove 111 enables the sealing ring 41 to be accurately positioned on the mounting port 11 during installation, avoiding the problem of poor sealing caused by position deviation.

[0036] Refer to Figure 4 , for the temperature-measurable spiral ribbon stirring reactor of this embodiment, the spiral ribbon stirring reactor further includes a clamping assembly 5. The clamping assembly 5 is located inside the kettle body 1. The clamping assembly 5 includes a clamping plate 51. The clamping plate 51 is located between the mounting port 11 and the stirring blade 23. A clamping hole 511 is provided on the clamping plate 51. The stirring shaft 22 passes through the clamping hole 511 so that the stirring shaft 22 can rotate relative to the clamping hole 511. The clamping plate 51 is used to clamp the stirring shaft 22 to prevent the stirring shaft 22 from shaking. The clamping plate 51 tightly clamps the stirring shaft 22 through the clamping hole 511, effectively restricting the shaking of the stirring shaft during rotation. Moreover, by sleeving the stirring shaft 22, the clamping plate 51 forms an additional sealing barrier on the basis of the original sealing of the sealing ring. This double-sealing mechanism can more effectively prevent material leakage and ensure the stability of the environment inside the reactor.

[0037] Refer to Figure 5 and Figure 6 , for the temperature-measurable spiral ribbon stirring reactor of this embodiment, the clamping assembly 5 further includes a connecting piece 52 and a support rod 53. The support rod 53 is fixed on the clamping plate 51. First connecting holes 521 and second connecting holes 522 are respectively provided at both ends of the connecting piece 52. The support rod 53 passes through the first connecting hole 521 to be connected with the connecting piece 52, and the stirring shaft 22 passes through the second connecting hole 522 to be connected with the connecting piece 52. The second connecting hole 522, the clamping hole 511, and the stirring shaft 22 are coaxially arranged. The addition of the connecting piece 52 and the support rod 53 makes the overall structure of the clamping assembly 5 more robust. During the stirring process, these components can effectively disperse and transmit the stress and vibration generated by the stirring shaft, thereby improving the structural strength of the entire clamping assembly.

[0038] Refer to Figure 5 and Figure 6, for the ribbon-type stirring reactor capable of measuring temperature in this embodiment, there are multiple connecting pieces 52 and support rods 53. Each connecting piece 52 and each support rod 53 are arranged in one-to-one correspondence. Each support rod 53 is arranged around the clamping hole 511 to form a multi-point support structure for the stirring shaft 22. When the stirring shaft 22 passes through the clamping hole 511, through the cooperation of each connecting piece 52 and each support rod 53, the clamping assembly 5 supports the stirring shaft 22 from multiple directions. The multiple connecting pieces 52 and support rods 53 support the stirring shaft 22 from multiple directions, forming an all-round and multi-point stable structure. This design greatly enhances the stability of the stirring shaft during rotation and reduces shaking.
