[0041] Before the chemical reactor is put into use, one of the flanges 21 is passed into the inside of the conical shell 2, and then the right baffle plate 3 is pushed or pulled to move on the inner wall of the middle shell 1, taking the left movement of the right baffle plate 3 as an example, the left movement of the right baffle plate 3 will drive the L-shaped pipe 13 to move left along the movable groove 12, and the L-shaped pipe 13 will be inserted into the left groove 11 for avoidance during the left movement of the L-shaped pipe 13, the left end of the L-shaped pipe 13 is always connected with the left groove 11, the right end of the L-shaped pipe 13 is connected with the position close to the right side of the inside of the middle shell 1, the left groove 11 is connected with the second joint 15 through the second connecting hole 16, and the second joint 15 is responsible for the cold and hot source, the first joint 14 is responsible for the cold and hot source, the cold and hot source is divided into a heat source and a cold source, and the cold and hot source is selectively used according to the reaction requirement, the left movement of the right baffle plate 3 will also cause the activity of the reaction tube 4 and the right end of the central column 5, the right baffle plate is in sealing connection with the central column 5 and the reaction tube 4, so that the space between the two baffle plates 3 can be sealed after the left movement of the right baffle plate 3, the space between the two baffle plates 3 is the shell side, the space flowing in the reaction tube 4 is the tube side, the first spring is arranged between the left end of the shell side and the baffle plate 6, between adjacent baffle plates 6 and between the rear end of the shell side and the baffle plate 6, so that the plurality of baffle plates 6 will be close to each other and be folded left during the left movement of the right baffle plate 3, and the length of the shell side will be shortened after the two baffle plates 3 are close to each other; conversely, if the right movement of the right baffle plate 3 is controlled, the right baffle plate 3 will drive the L-shaped pipe 13 to move right along the movable groove 12, the right baffle plate 3 will be active with the central column 5 and the reaction tube 4, the distance between the two baffle plates 3 is increased, and the plurality of baffle plates 6 are away from each other and are unfolded; after the length of the shell side is adjusted, the chemical reactor can be suitable for the reaction requirement of different products, and the application range is wider; then the chemical reactor is put into use, and the mixed fluid raw material flows from left to right, the mixed fluid raw material will flow into the left position of the flange 21 and the conical shell 2, the raw material will flow into the tube side along the left end of the reaction tube 4, the cold and hot source will flow along the second joint 15, the second joint 15 will flow into the left groove 11 along the second connecting hole 16, and the cold and hot source in the left groove 11 will flow into the right position of the shell side along the L-shaped pipe 13, since the plurality of baffle plates 6 are arranged in the shell side, and the notches 61 on the adjacent baffle plates 6 are staggered, so that the cold and hot source at the right position of the shell side will pass through the outer wall of the reaction tube 4 and pass through the plurality of baffle plates 6, so that the cold and hot source flows from right to left under disturbance, and finally flows out along the first joint 14, the cold and hot source will transfer cold and heat to the raw material in the reaction tube 4, so that the raw material can react at the corresponding temperature, meet the reaction requirement of the raw material in the reaction tube 4, and the raw material in the reaction tube 4 reacts and then flows into the right conical shell 2 along the right end of the reaction tube 4, and finally flows out along the right position of the flange 21; the length of the shell side is changed by adjusting the distance between the two baffle plates 3, so that the chemical reactor can be suitable for the reaction requirement of different products, and the application range is wide.

[0042] In the embodiment, the central column 5 is combined by a left column 51 and a threaded column 52; the left hole 53 at the right end of the left column 51 is movably connected with the left end of the threaded column 52; the left column 51 is fixedly connected with the left stop disc 3, and the threaded column 52 is threadedly and sealingly connected with the right stop disc 3; the right end of the threaded column 52 is fixedly connected with an end face gear 54; the end face gear 54 is engaged with a cylindrical gear 55; the inner and outer walls of the right conical shell 2 are movably and sealingly connected with a rotating rod 22; the inner end of the rotating rod 22 is connected with the cylindrical gear 55, and the outer end of the rotating rod 22 is connected with a handle 23.

[0043] In the embodiment, the number of the cylindrical gears 55 is two; the rotating rod 22 passes through and is fixedly connected with the two cylindrical gears 55; the two cylindrical gears 55 are arranged close to the inner edge of the end face gear 54 at the same time; the end face of the upper position cylindrical gear 55 is movably connected with a rotating ring 56; the inner wall of the conical shell 2 and the rotating ring 56 are connected through a second spring 57; the second spring 57 is sleeved on the outer wall of the corresponding rotating rod 22.

[0044] When the two flanges 21 at the end of the chemical reactor are connected, and the length of the shell side needs to be adjusted again, the right stop disc 3 does not need to be adjusted through the flanges 21 and the inside of the conical shell 2. Only the handle 23 needs to be pressed or pulled. In the initial state, since the two cylindrical gears 55 are connected by the rotating rod 22 and the face gear 54 meshes with the two cylindrical gears 55 at the same time, the two cylindrical gears cannot be driven by the face gear 54 at the same time. This makes the face gear 54 belong to a locked rotation. When the handle 23 is pressed or pulled, the handle 23 will drive the rotating rod 22 to move downward. The rotating rod 22 will drive the two cylindrical gears 55 to move downward during the downward movement. The upper cylindrical gear 55 will drive the rotating ring 56 to move downward during the downward movement of the upper cylindrical gear 55. The rotating ring 56 will overcome the tension of the second spring 57 during the downward movement of the rotating ring 56. After the upper cylindrical gear 55 moves downward, the meshing position of the upper cylindrical gear 55 on the face gear 54 moves away. After the lower cylindrical gear 55 moves downward, the lower cylindrical gear 55 does not disengage from the face gear 54. In this way, the state of the double-cylinder gear 55 and the face gear 54 is switched to the state of a single-cylinder gear 55 and the face gear 54. The face gear 54 is unlocked. When the handle 23 is pulled to drive the rotating rod 22 to move upward, the rotating rod 22 will drive the two cylindrical gears 55 to move upward during the upward movement. The upper cylindrical gear 55 will drive the rotating ring 56 to move upward and overcome the elastic force of the second spring 57 during the upward movement of the upper cylindrical gear 55. After the lower cylindrical gear 55 moves upward, the lower cylindrical gear 55 disengages from the face gear 54. After the upper cylindrical gear 55 moves upward, the upper cylindrical gear 55 remains engaged with the face gear 54. In this way, the face gear 54 is unlocked. Therefore, the two cylindrical gears 55 in the initial state can unlock the face gear 54, and the cylindrical gear 55 in the enabled state can unlock the face gear 54. When one of the cylindrical gears 55 meshes with the face gear 54, rotating the handle 23 drives the rotating rod 22 to rotate. The rotating ring 56 is rotationally connected to the upper cylindrical gear 55, so the rotation of the upper cylindrical gear 55 is not affected. During the rotation of the rotating rod 22, one of the cylindrical gears 55 rotates with the face gear 54. During the rotation of the face gear 54, the threaded column 52 rotates. The threaded column 52 is in threaded transmission sealing connection with the right stop disc 3. Specifically, a first helical groove can be provided on the threaded column 52. The first helical groove is movably connected to a first block (not shown in the figure) in the helical direction. The block is fixedly connected to the stop disc 3 to achieve threaded transmission while being sealed. When the threaded column 52 rotates, the right stop disc 3 moves left or right, and the length of the shell side is adjusted. The adjustment is more convenient and faster without the need to adjust through the flanges 21 and the conical shell 2.After the completion of the shell course adjustment, loosen the handle 23, the second spring 57 will drive the two cylindrical gear 55 drive the rotating rod 22 along the rotating rod 22 axial movement, so that the two cylindrical gear 55 with end face gear 54 meshing, realize the locking of end face gear 54, also make the position of the right disc 3 is locked, thereby making the shell course space size is more stable after locking.

[0045] In this embodiment, the right reverse tube 42 outer diameter is less than the left reverse tube 41 outer diameter; the baffle 6 through the elastic sealing ring 62 and the outer wall of the threaded column 52, the outer wall of the right reverse tube 42, the inner wall of the right shell 18 activity sealing contact; the left end of the threaded column 52 rotating connection with the rotating block 521; the left end of the left hole 53 and the rotating block 521 through the third spring 522 connection.

The threads of the second screw 78 are arranged in the lower half. The driving groove 76 is communicated with the driven groove 72 through a liquid hole 79 between the lower inner wall of the driving groove 76 and the left wall of the driven groove 72. The pull forces of the plurality of pull springs 75 are different.

[0049] In the embodiment, the shielding plate 74 is a fan-shaped plate. A plurality of shielding plates 74 are arranged to form a ring-shaped structure. The outer edges of the plurality of shielding plates 74 can contact the inner wall of the conical shell 2 after moving leftward.

[0053] Embodiment 6: The chemical reactors are connected and communicated through the connecting pieces 24; the leftmost chemical reactor is connected with the mixing device 9 through the photo initiation device 8, and the fluid raw materials enter the mixing device 9 for mixing, and then enter the chemical reactor along the photo initiation device 8 for reaction.

[0054] In this embodiment, the connecting pieces 24 are straight pipes or elbow pipes, and instruments (not shown in the figure) are connected in series on the connecting pieces 24.

[0055] Taking three chemical reactors as an example, the raw materials, i.e. medium 1, medium 2, medium 3 and medium 4, are pumped into the mixing device 9 for mixing under the action of the pump, and the specific amount of raw materials is increased or reduced according to the demand. The raw materials in the mixing device 9 will enter the photo initiation device 8. The photo initiation device 8 is mainly through a pipe, which is a crystal material and is reinforced by a steel sleeve. The wavelength of light fluctuates between 380 nm and 450 nm, which is determined according to the material condition. The light point can also be along the direction of the pipeline. Two or four initiation points are arranged on both sides. The raw materials passing through the photo initiation device 8 will enter the first chemical reactor. The first chemical reactor is mainly used for the initial reaction. The initial reaction may need to be operated by heating. Steam or hot water enters the shell side of the first chemical reactor. After the raw materials pass through the photo initiation, the material starts to react. The flow of the heat source controls the speed of the material reaction. The raw materials will enter the second chemical reactor after reacting in the first chemical reactor. This is the stable period of the reaction. Steam or hot water is used to control the reaction temperature. The operation of the second chemical reactor is similar to that of the first chemical reactor, which aims to improve the reaction yield. Then it enters the third chemical reactor. In order to further improve the reaction rate, the raw materials are cooled by the refrigerant. Finally, the qualified products are obtained. When the reaction is completed, the online detection device may be used for detection. If the detection is unqualified, the material will not enter the subsequent process of qualified products, but will return to the front of the first chemical reactor or the second chemical reactor. According to the detection result, the material is selected to enter the first chemical reactor or the second chemical reactor for re-reaction. The connecting pieces 24 between multiple chemical reactors can be straight pipes or elbow pipes. The direction of the material can be adjusted arbitrarily according to the space requirement. In addition, some instruments can be added on the connecting pieces 24, such as temperature, pressure, flow, etc. The number of chemical reactors can be customized according to the demand. The specific installation can be horizontal or vertical, which is generally selected to be horizontal according to the specific gravity of the material and the space requirement of the site. If it is vertical, the material density is lighter, and the material inlet may be considered at the top and the outlet at the bottom. The position, size and number of the heat source inlet and outlet of the reactor, including the cold source inlet and outlet, need to be arranged according to the heat balance calculation of the material reaction. The safety valve or bursting disc port and the detection port are connected on the connecting piece 24.

[0056] The various components of the chemical reactor are fabricated and then assembled. The conical shell 2 is a variable-diameter sleeve, and the reaction tube 4 has a diameter of 4-10mm. Of course, other diameters can also be selected, depending on the reaction requirements. The material, wall thickness, quantity, and length of a single tube can be designed according to different process systems. For example, the wall thickness of the reaction tube 4 needs to be calculated based on the reaction pressure and corrosiveness. The quantity of reaction tubes 4 * the cross-sectional area of ​​a single tube ≥ 3 * the cross-sectional area of ​​the reactor inlet and outlet tubes. The selection of the tube diameter mainly depends on the reaction pressure; higher pressure requires thicker walls and larger diameter tubes, while lower pressure requires thinner walls and smaller diameter tubes. Currently, the wall thickness mainly fluctuates between 0.3mm and 2mm, and is custom-designed. Additionally, wall thickness and pipe diameter are related to the product's viscosity, thermal conductivity, and production capacity per unit time. The main materials for reaction tube 4 include 304, 316L, 32168, titanium, and Hastelloy C276. The middle shell 1 and cone shell 2 primarily consider the design pressure of the refrigerant or heat medium, and the medium's properties. Carbon steel is generally selected, with wall thickness and pressure rating based on the refrigerant or heat medium's design pressure. The baffle plate 6 improves the heat exchange uniformity of reaction tube 4. Reaction tube 4 can be designed with external fins based on heat balance calculations. The fin spacing and height are calculated based on the heat dissipation; the fin design should not affect... The dynamic baffle plate 6 can be made of aluminum, 304, or 316L fins. The reaction rate optimization method is based on online spectral analysis data, and non-compliant materials are returned via a diversion valve. This embodiment supports rapid expansion through modular design to adapt to diverse production needs. The small pipe diameter and microfin structure improve reaction efficiency. The dynamic baffle plate 6 design improves heat exchange. The closed-loop feedback system reduces raw material waste and improves product consistency. The connection method between chemical reactors allows for arbitrary adjustment of material direction, and the flow direction is adjusted in real time based on sensor data to optimize the reaction path, which is relatively novel in the existing technology.
