Description

Technical Field

[0001] This utility model relates to the field of tubular reactor technology, specifically to a continuous tubular reactor. Background Technology

[0002] Tubular reactors, as a common and efficient reaction device, are widely used in continuous production processes in industries such as chemical, pharmaceutical, and food. Their structure is typically a cylindrical container with a large length-to-diameter ratio, and internal components such as stirring and heat exchangers can be installed. They are suitable for multiphase reaction systems such as liquid-liquid, gas-liquid, and solid-liquid reactions.

[0003] Traditional tubular reactors mostly use fixed stirring blades, but they lack the ability to flexibly adjust the stirring intensity and method when dealing with different material properties. This leads to poor mixing effect, low reaction efficiency or excessive energy consumption under certain process conditions. For example, in scenarios where different shearing or pumping capabilities are required for different sections of the reactor, it is difficult to meet the process requirements. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a continuous tubular reactor, which solves the problem of the lack of flexible adjustment of stirring blades in tubular reactors.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a continuous tubular reactor, comprising an outer reaction cylinder, a motor, and an inner reaction cylinder, and further comprising a rotating shaft, stirring blades, a transmission component, and a regulating rod. The number of outer reaction cylinders is two sets, and the two sets of outer reaction cylinders are meshed together. The motor is fixedly installed at the top of the outer reaction cylinder, and the inner reaction cylinder is fixedly installed between the two sets of outer reaction cylinders. The rotating shaft is rotatably installed inside the inner reaction cylinder, and the output end of the motor is connected to the top end of the rotating shaft. The stirring blades are rotatably installed on the surface of the rotating shaft. The transmission component is located inside the rotating shaft and connected to the stirring blades. The regulating rod is located at the bottom of the inner reaction cylinder, and the rotating end of the regulating rod passes through the bottom end of the rotating shaft and is connected to the transmission component.

[0006] The outer reaction cylinder includes a sleeve, a heat insulation plate, and a heating plate. The heat insulation plate is fixedly installed inside the sleeve, and the heating plate is fixedly installed inside the heat insulation plate. The outer side of the inner reaction cylinder is in contact with the inner wall of the heating plate.

[0007] The inner reaction cylinder includes a cylinder body, a feed pipe, and a discharge pipe. The cylinder body is fixedly installed inside the outer reaction cylinder, the feed pipe is fixedly installed at the bottom of the cylinder body, and the discharge pipe is fixedly installed at the top of the cylinder body.

[0008] The transmission components include a worm gear, a worm, a driven wheel, and a driving wheel. The worm gear is rotatably mounted inside the rotating shaft, and one end of the worm gear is fixedly connected to the inner reaction cylinder. The worm is rotatably mounted inside the rotating shaft, and the worm gear and the worm are meshed together. The driven wheel is fixedly mounted to one end of the worm. The driving wheel is rotatably mounted inside the rotating shaft, and the driven wheel and the driving wheel are meshed together. A limit groove is formed inside the driving wheel, and the limit groove is correspondingly set with the regulating rotating rod.

[0009] The number of worm gears, worm shafts and driven gears is two sets, and they are arranged symmetrically about the driving gear.

[0010] The control lever includes a base plate, a lever body, and a limiting block. The base plate is fixedly installed at the bottom of the reaction cylinder. The bottom end of the rotating shaft is rotatably connected to the top of the base plate, and the lever body penetrates through the base plate to the interior of the rotating shaft. The limiting block is fixedly installed on the surface of the lever body.

[0011] The number of stirring blades, transmission components and limiting blocks are multiple sets, and they are arranged at equal intervals along the axial direction of the rotating shaft. The positions of the stirring blades and transmission components are kept synchronized, and the spacing between each set of limiting blocks and the stirring blades and transmission components increases from bottom to top.

[0012] The control lever also includes a positioning plate, a clamping plate, and a screw. The positioning plate is fixedly sleeved on the bottom surface of the lever body. An L-shaped plate is fixedly installed on the surface of the base plate, and the screw is threaded onto the surface of the L-shaped plate. The clamping plate is rotatably installed on one end of the screw. The positioning plate and the clamping plate are slidably inserted into each other.

[0013] The beneficial effects of this utility model are as follows: This invention utilizes a rotating rod to drive a drive wheel connected to the rod surface via a limiting block. The drive wheel drives a driven wheel meshing with it, which in turn drives a worm gear. The worm gear then drives a worm wheel meshing with it, which in turn drives a stirring blade. By adjusting the tilt angle of the stirring blade, the pumping capacity or shearing force of the rotating shaft and stirring blade can be selected based on the properties of the material to be processed. By pushing the rod to slide, the insertion position of the positioning plate and the clamping plate is changed, thereby adjusting the connection between the limiting block at the corresponding height position and the drive wheel. The limiting blocks at other positions are disconnected from the drive wheel, allowing for individual control of the stirring blades at different positions. This enables the pumping or shearing effect on the material inside a certain section of the reaction cylinder to be enhanced as needed. Attached Figure Description

[0017] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 7 The present invention will be further described below.

[0018] A continuous tubular reactor includes an outer reaction cylinder 1, a motor 2, and an inner reaction cylinder 3. It is characterized by further including a rotating shaft 4, stirring blades 5, a transmission component 6, and a regulating rod 7. The number of outer reaction cylinders 1 is two sets, and the two sets of outer reaction cylinders 1 are meshed together. The motor 2 is fixedly installed at the top of the outer reaction cylinder 1, and the inner reaction cylinder 3 is fixedly installed between the two sets of outer reaction cylinders 1. The rotating shaft 4 is rotatably installed inside the inner reaction cylinder 3, and the output end of the motor 2 is connected to the top end of the rotating shaft 4. The stirring blades 5 are rotatably installed on the surface of the rotating shaft 4. The transmission component 6 is disposed inside the rotating shaft 4 and connected to the stirring blades 5. The regulating rod 7 is disposed at the bottom of the inner reaction cylinder 3, and the rotating end of the regulating rod 7 passes through the bottom end of the rotating shaft 4 and is connected to the transmission component 6. Specifically, the outer reaction cylinder 1 heats the inner reaction cylinder 3. The two meshing outer reaction cylinders 1 facilitate the control of their opening and closing, allowing observation of the internal condition of the inner reaction cylinder 3. The motor 2 drives the rotating shaft 4 to rotate, causing the stirring blades 5 to stir the material inside the inner reaction cylinder 3, promoting mixing. The connection position of the transmission component 6 and the control rod 7 is switched, allowing the tilt angle of each set of stirring blades 5 to be adjusted by the control rod 7.

[0019] The outer reaction cylinder 1 includes a sleeve 101, a heat insulation plate 102, and a heating plate 103. The heat insulation plate 102 is fixedly installed inside the sleeve 101, and the heating plate 103 is fixedly installed inside the heat insulation plate 102. The outer side of the inner reaction cylinder 3 is in contact with the inner wall of the heating plate 103. Specifically, the heat loss is reduced by the heat insulation plate 102, and the reaction inner cylinder 3 is heated by the heating plate 103 to promote the reaction of the materials inside the reaction inner cylinder 3.

[0020] The reaction inner cylinder 3 includes a cylinder body 301, a feed pipe 302, and a discharge pipe 303. The cylinder body 301 is fixedly installed inside the heating plate 103. An observation window is embedded in the front side of the cylinder body 301. The feed pipe 302 is fixedly installed at the bottom end of the cylinder body 301, and the discharge pipe 303 is fixedly installed at the top end of the cylinder body 301. Specifically, the material to be processed is input into the cylinder 301 through the feed pipe 302, and the processed material in the cylinder 301 is output to the subsequent storage container or processing step through the discharge pipe 303.

[0021] The transmission component 6 includes a worm gear 601, a worm 602, a driven wheel 603, and a driving wheel 604. The worm gear 601 is rotatably mounted inside the rotating shaft 4, and one end of the worm gear 601 is fixedly connected to the reaction inner cylinder 3. The worm 602 is rotatably mounted inside the rotating shaft 4, and the worm gear 601 and the worm 602 are meshed together. The driven wheel 603 is fixedly mounted to one end of the worm 602. The driving wheel 604 is rotatably mounted inside the rotating shaft 4, and the driven wheel 603 and the driving wheel 604 are meshed together. A limit groove is formed inside the driving wheel 604, and the limit groove is correspondingly set with the regulating rotating rod 7. Specifically, the worm gear 601 drives the stirring blade 5 to rotate, adjusting its tilt angle. The worm 602 meshes with the worm gear 601, causing the worm gear 601 to rotate. The driven wheel 603 drives the worm 602 to rotate accordingly. The driving wheel 604 meshes with the driven wheel 603, causing the driven wheel 603 to rotate. The limiting groove of the driving wheel 604 is connected to the limiting block 703, so that the rotation of the rod body 702 can drive the driving wheel 604 to rotate accordingly.

[0022] There are two sets of worm gear 601, worm 602 and driven gear 603, which are arranged symmetrically about the driving gear 604. Specifically, the tilting direction of the two sets of stirring blades 5 is kept synchronized by the centrally symmetrical worm gear 601.

[0023] The control lever 7 includes a base plate 701, a lever body 702, and a limiting block 703. The base plate 701 is fixedly installed at the bottom of the cylinder 301. The bottom end of the rotating shaft 4 is rotatably connected to the top of the base plate 701. The lever body 702 passes through the base plate 701 to the interior of the rotating shaft 4. A handle is fixedly installed at the bottom end of the lever body 702. The limiting block 703 is fixedly installed on the surface of the lever body 702. The limiting block 703 is correspondingly set with the limiting groove of the drive wheel 604. Specifically, the rod 702 drives the limiting block 703 to rotate, causing the drive wheel 604 connected to the limiting block 703 to rotate accordingly, adjusting the tilt angle of the stirring blade 5 at the corresponding position. By turning the handle of the rod 702, the rod 702 is driven to rotate. By pushing the rod 702 up and down, the limiting block 703 is connected to the limiting groove of the drive wheel 604.

[0024] The number of stirring blades 5, transmission components 6 and limiting blocks 703 are multiple sets, and they are arranged at equal intervals along the axial direction of the rotating shaft 4. The positions of stirring blades 5 and transmission components 6 are kept synchronous, and the spacing between each set of limiting blocks 703 and stirring blades 5 and transmission components 6 increases from bottom to top. Specifically, by adjusting the connection between the limiting block 703 and the limiting groove of the drive wheel 604 through the up-and-down movement of the rod 702, the stirring blades 5 and the transmission component 6 of this group are operated by the rotation of the rod 702, while the other groups of stirring blades 5 and transmission components 6 are not affected by the rotation of the rod 702.

[0025] The control lever 7 also includes a positioning disc 704, a clamping plate 705, and a screw 706. The positioning disc 704 is fixedly sleeved on the bottom surface of the lever body 702. An L-shaped plate is fixedly installed on the surface of the base plate 701, and the screw 706 is threaded onto the surface of the L-shaped plate. The clamping plate 705 is rotatably installed on one end of the screw 706. The positioning disc 704 and the clamping plate 705 are slidably inserted into each other. Specifically, the rotation of the screw 706 drives the card plate 705 to move horizontally, controlling the connection and disconnection of the positioning disk 704 and the card plate 705. The connection between the positioning disk 704 and the card plate 705 determines the corresponding position of the stirring blade 5 controlled by the rod 702.

[0026] In summary: When using this utility model, the operator continuously transports various materials to be processed into the cylinder 301 along the feed pipe 302. The materials flow from bottom to top along the cylinder 301. During the flow, the heating plate 103 transfers heat to the reaction cylinder 3, promoting the reaction of the materials inside the cylinder 301. At the same time, the motor 2 drives the rotating shaft 4 to rotate inside the cylinder 301, so that the stirring blades 5 on the surface of the rotating shaft 4 promote the thorough mixing of various materials inside the cylinder 301. Finally, the reacted materials are discharged from the device through the discharge pipe 303 and enter the subsequent processing steps or storage container. Before processing begins, the tilt angles of the stirring blades 5 at different heights within the cylinder 301 are adjusted according to the properties of the materials involved in the reaction. This pushes the rod 702 up and down, connecting the limiting block 703 on the surface of the rod 702 with the drive wheel 604 at the corresponding height. Then, rotating the rod 702 causes the drive wheel 604 to rotate, which in turn drives the driven wheel 603 meshing with it. The driven wheel 603 then drives the worm gear 602 to rotate. The worm gear 601 meshing with it rotates, causing the worm gear 601 to control the rotation of the stirring blade 5, thereby adjusting its tilt angle. When it is necessary to switch the stirring blade 5 whose tilt angle needs to be adjusted, the screw 706 is turned to move the clamping plate 705, causing the connection between the clamping plate 705 and the positioning plate 704 to be disconnected. The rod body 702 is moved again to change the connection between the drive wheel 604 and the limit block 703 at the corresponding height position, and the clamping plate 705 is reset. The tilt angle adjustment is repeated until the requirement is met, and the above-mentioned material reaction operation can be performed.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
