Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, in particular to a mixing reaction device and method for preparing p-chlorophenyl glycol formal. Background Art

[0002] The preparation of p-chlorophenyl glycol formal mainly involves taking p-chlorobenzaldehyde as a raw material, combining it with ethylene glycol through a condensation reaction, and completing it in the presence of p-toluenesulfonic acid as a catalyst in a xylene solvent.

[0003] A liquid medicine mixing reaction device disclosed in the patent application with reference publication number CN220835158U drives the second stirring rod and the second blade to rotate through the second gear, and the first stirring rod and the second stirring rod rotate together, so that the liquid medicine is stirred more evenly and efficiently. Through the setting of the connecting pipe, the valve, the first threaded pipe, the second threaded pipe, the water pump, the rubber ring and the water tank, the water pump is connected to the first threaded pipe by rotating the second threaded pipe. After the mixing box is finished working, the water pump works to transport the water to the mixing box. When the water tank is suitable, the valve and the water pump are closed, and the reduction motor drives the first stirring rod and the second stirring rod to start stirring, and then the discharge port is opened to discharge the cleaning water. The cleaning is simple and convenient, and the efficiency is higher. The above-mentioned mixing reaction device in the prior art has the following defects in actual use: The current mixing reaction device can only mix materials by a single axial stirring method. The raw materials at the bottom of the mixing box and attached to the inner wall of the mixing box are difficult to be stirred because they are far away from the stirring shaft. It takes a longer stirring time to mix with the raw materials at the stirring center, thereby prolonging the stirring time and greatly reducing the mixing efficiency. For mixing reaction equipment that adopts a design in which the stirring rod and the mixing box are separated, the mixing box needs to be separated from the stirring after the material mixing is completed so that the materials in the mixing box can be handled separately. However, after the stirring rod is manufactured, the width of its stirring area is fixed, which means that it can only be adapted and inserted into the mouth of the mixing box of corresponding width for installation or removal. For those mixing boxes whose mouth width is smaller than the width of the stirring rod, the stirring rod cannot be smoothly pulled out. This feature limits the range of mixing boxes in which the stirring rod can be used.

[0004] Therefore, the present invention proposes a mixed reaction device and method for preparing p-chlorophenyl glycol formal to solve the above problems. Summary of the invention

[0016] The present invention provides a mixed reaction device and method for preparing p-chlorophenyl glycol formal. Compared with the prior art, it has the following beneficial effects: 1. A mixing reaction device and method for preparing p-chlorophenyl glycol formal. By setting a mixing mechanism, a wedge-shaped scraper plate arranged at the bottom can be used to scrape and stir the raw material sediment attached to the bottom of the mixing barrel, thereby avoiding the adhesion of the prepared raw materials to the bottom of the mixing barrel, and ensuring the mixing uniformity of the prepared raw materials in the bottom area of ​​the mixing barrel. By setting a plurality of multifunctional spoiler components on the outer wall of the stirring shaft and an air motor running according to a preset program, the air motor can run alternately in a high-speed rotation mode and a low-speed rotation mode in a cycle. In the two rotation modes, Two centrifugal forces of different sizes are generated. Under the cyclic and alternating action of the two centrifugal forces of different sizes, the multifunctional spoiler component enables the No. 2 support arm to return to its original position after being away from the No. 1 support arm, and enables the transverse spoiler to reciprocate between the inner wall of the mixing barrel and the No. 1 support arm, thereby realizing a transverse driving force on the prepared raw materials, and can push the prepared raw materials to a position away from the center of the mixing barrel. Moreover, when the transverse spoiler is reset, it can push the prepared raw materials located near the inner wall of the mixing barrel toward the stirring shaft, thereby realizing the transverse flow of the prepared raw materials in the two areas, which is beneficial to speeding up the mixing speed between different raw materials.

[0017] 2. A mixing reaction device and method for preparing para-chlorophenyl glycol formal. By setting a multifunctional spoiler component, the longitudinal spoiler unit can allow the prepared slurry in the mixing barrel to enter the input pipe section through the bell pipe during the rotation of the synchronous stirring shaft, and use the kinetic energy of the liquid flow to drive the impeller to rotate, so as to achieve the purpose of driving the turbofan to rotate. The upward suction force generated by the rotation of the turbofan can transport the prepared raw materials located in the bottom area of ​​the mixing barrel through the input pipe section, the throat and the output pipe section to the top of the mixing barrel, thereby realizing the circulating flow and stirring of the prepared raw materials in the upper and lower areas of the mixing barrel, avoiding the situation where the prepared raw materials are deposited at the bottom of the mixing barrel and cannot be fully stirred, thereby ensuring the adequacy of the mixing process.

[0018] 3. A mixing reaction device and method for preparing p-chlorophenyl glycol formal, wherein a transverse spoiler and a conducting pipe are arranged in a multifunctional spoiler assembly, and the transverse spoiler can be close to the inner wall of a mixing barrel under the action of centrifugal force. By using the Venturi tube principle, a negative pressure lower than the outside can be formed at the position when the slurry is prepared through the throat position, and the negative pressure generates a suction force in the No. 2 channel in the transverse spoiler, and the slurry attached to the inner wall of the mixing barrel and not fully stirred can be sucked into the No. 2 channel during the rotation process, and the part of the slurry is transported to the central area of ​​the mixing barrel again through the longitudinal spoiler unit, so that the transverse stirring and longitudinal stirring methods are combined. Combined with the above, this part of the slurry can be quickly mixed with the raw materials in other positions, shortening the overall mixing reaction time, and during the cleaning of the reactor, the lateral spoiler is able to rotate close to the inner wall of the mixing barrel at a certain speed of the pneumatic motor, so that the p-chlorophenyl glycol formal residues attached to the inner wall of the mixing barrel can be peeled off and sucked away from the inner wall of the mixing barrel through the No. 2 channel to avoid the scraped residues from adhering again, thereby improving the cleaning speed and cleaning effect of the reactor assembly, so that the multifunctional spoiler assembly not only has the stirring and mixing function, but also can take into account the cleaning function when cleaning the reactor assembly, and has high practicality.

[0019] 4. A mixing reaction device and method for preparing para-chlorophenyl glycol formal, wherein a multifunctional spoiler component can be stretched out only under the action of a large centrifugal force to form a wider stirring range, and after losing the action of the centrifugal force, multiple multifunctional spoiler components can be automatically folded and stored to form a narrower stirring range, so that the multifunctional spoiler component can be easily and quickly withdrawn from the mixing barrel, and it is also convenient for handling the raw materials in the mixing barrel, and the different stirring widths of the multifunctional spoiler component can be controlled by controlling the different speeds of the pneumatic motor, so that it can form a stirring radius compatible with a variety of target mixing barrel inner diameters, thereby being suitable for the stirring work of mixing barrels with various inner diameters, thereby expanding the application range of the multifunctional spoiler component.

By changing the different speeds of the pneumatic motor 51, the angle between the second support arm 564 and the first support arm 561 can be changed, that is, the reciprocating swinging action of the transverse spoiler 5612 between the stirring shaft 52 and the inner wall of the mixing barrel 2 is realized; The reaction kettle assembly includes a mixing barrel 2 and a barrel cover 3 detachably arranged on the top of the mixing barrel 2. The mixing barrel 2 and the barrel cover 3 are connected by a lock during mixing. After the lock is unlocked, the mixing barrel 2 and the barrel cover 3 can be separated.

The feeding tube is used to add raw materials into the mixing barrel 2 during mixing, and the endoscope is used to observe the raw materials inside the mixing barrel 2 and the mixing state.

[0024] like Figure 7-Figure 13A second embodiment is shown, in which the mixing execution component includes a mounting sleeve 54 fixedly sleeved on the outer wall of the stirring shaft 52 by bolts, and a plurality of mounting seats 55 are evenly and fixedly arranged on the outer wall of the mounting sleeve 54.

The multifunctional spoiler component 56 includes a folding arm unit and a multi-directional spoiler component connected to the folding arm unit. The folding arm component is extended or folded under the alternating action of centrifugal forces of different magnitudes to drive the multi-directional spoiler component to approach or move away from the inner wall of the mixing barrel 2. The folding arm unit includes a No. 1 support arm 561 installed in one of the mounting seats 55, a spring mounting tube 562 is fixedly provided at the end of the No. 1 support arm 561 away from the mounting seat 55, a volute spring 563 is movably provided inside the spring mounting tube 562, and a limiting groove for positioning one end of the volute spring 563 is provided on the inner wall of the spring mounting tube 562, one end of the volute spring 563 is detachably provided in the limiting groove, a spring limiting sleeve 565 is provided on the outer wall of the spring mounting tube 562 for sealing and rotating sleeve, a limiting column 566 is fixedly provided on the inner wall of the spring limiting sleeve 565, a positioning groove 567 for positioning the other end of the volute spring 563 is provided on the outer wall of the limiting column 566, one end of the volute spring 563 away from the limiting groove is detachably provided in the positioning groove 567, and a No. 2 support arm 564 for connecting with the multi-directional spoiler unit is also fixedly provided on one side of the outer wall of the spring limiting sleeve 565; The multi-directional spoiler assembly includes a longitudinal spoiler unit 568 for promoting the longitudinal flow of the prepared raw material slurry and spoiler plates 569 fixedly arranged on both sides of the outer wall of the longitudinal spoiler unit 568. A No. 1 channel 5610 is provided at relative positions on both sides below the outer wall of the longitudinal spoiler unit 568. A trumpet pipe 5611 for introducing the prepared raw material slurry is fixedly arranged in one of the No. 1 channels 5610, and a transverse spoiler plate 5612 for promoting the transverse flow of the prepared raw material slurry is also fixedly arranged on the outer wall of the trumpet pipe 5611 near the inner wall of the mixing barrel 2. A No. 2 channel 5613 for sucking the prepared raw material slurry around the inner wall of the mixing barrel 2 into the longitudinal spoiler unit 568 is also provided on the outer wall of the transverse spoiler plate 5612. The transverse spoiler plate 5612 and the longitudinal spoiler unit 568 are connected by a conducting pipe 5614.

[0025] The longitudinal spoiler unit 568 includes a throat a1, the top and bottom of which are respectively fixedly provided with an output pipe section a2 and an input pipe section a3 connected to the inside thereof. The prepared raw material slurry flows through the throat a1 through the input pipe section a3 and is output through the top of the output pipe section a2, and forms a negative pressure less than the external pressure inside the throat a1. A suction component for sucking the prepared raw material slurry to be transported toward the output pipe section a2 is also provided at the bottom of the inner cavity of the input pipe section a3. The bottom end of the output pipe section a2 is a closed structure. The prepared slurry enters the longitudinal spoiler unit through the trumpet 5611 and the first channel 5610. In 568, a plurality of "S"-shaped spoilers are evenly and fixedly arranged on the inner wall of the output pipe segment a2, which are used to change the flow path of the prepared slurry through the output pipe segment a2 to speed up the mixing speed of multiple raw materials. The suction assembly includes an impeller 5615 rotatably arranged at the bottom of the inner cavity of the input pipe segment a3, and a turbofan 5616 is arranged above the impeller 5615. The turbofan 5616 and the impeller 5615 are fixedly connected by a transmission shaft 5617. The impeller 5615 uses the prepared slurry entering through the bell pipe 5611 to drive itself to rotate, so as to drive the turbofan 5616 to rotate synchronously to generate an upward suction force.

[0026] The embodiment of the present invention also provides a mixed reaction method for preparing p-chlorophenyl glycol formal, which is used for a mixed reaction device for preparing p-chlorophenyl glycol formal. The method comprises the following steps: Step 1, adding p-chlorobenzaldehyde and xylene solvent into the reaction kettle assembly, controlling the temperature at room temperature, and then adding ethylene glycol and p-toluenesulfonic acid in sequence; Step 2, heat preservation and stirring, the pneumatic motor 51 drives the stirring shaft 52 to cycle alternately at the preset speed 1 and the preset speed 2, and the mixing execution component stirs the prepared raw material slurry in the reactor component up and down and pushes and pulls it horizontally, and gradually heats it to 135°C, and maintains this temperature for heat preservation reaction for 24 hours; Step 3, after the reaction is completed, the solvent xylene and excess ethylene glycol are distilled off, and the residue is distilled out of the product through a distillation tower to obtain para-chlorophenyl glycol formal; the specific process is: first, the cylinder 14 is started to push the connecting plate 16 to move upward, and the two lifting frames 15 slide upward along the inner wall of the longitudinal bracket 12 at the corresponding position until the bottom of the mixing mechanism 5 is slightly higher than the top of the mixing barrel 2, and then the mixing barrel 2 is pushed to the bottom of the barrel cover 3, and then the cylinder 14 is started to pull down the connecting plate 16. During the downward movement of the two lifting frames 15, the barrel cover 3 and the mixing mechanism 5 are synchronously driven into the mixing barrel 2. When the wedge-shaped scraper 53 approaches the bottom of the inner cavity of the mixing barrel 2, the barrel cover 3 and the top of the mixing barrel 2 are abutted, and the barrel cover 3 and the mixing barrel 2 are locked by using a plurality of lock buckles evenly distributed on the outer wall of the mixing barrel 2; Add p-chlorobenzaldehyde, xylene solvent, ethylene glycol and p-toluenesulfonic acid into the mixing cylinder 2 in proportion through the feeding pipe on the top of the cylinder cover 3; Before adding raw materials into the mixing barrel 2, the speed of the pneumatic motor 51 is controlled by the pneumatic valve and the air pressure regulating valve. The pneumatic motor 51 is regulated according to the inner diameter size of the mixing barrel 2 to cycle alternately according to the preset speed one and the preset speed two during mixing. The preset speed one is higher than the preset speed two. When the pneumatic motor 51 stirs the mixture at the preset speed one, the transverse spoiler 5612 is away from the edge position of the longitudinal spoiler unit 568 under the action of centrifugal force and contacts the inner wall of the cavity of the mixing barrel 2, that is, the transverse spoiler 5612 can slide relative to the inner wall of the cavity of the mixing barrel 2. At the same time, the spring limit sleeve 565 rotates relative to the outer wall of the spring mounting cylinder 562, and the limit column 566 simultaneously drives the volute spring 563 to be compressed while rotating, and the pneumatic motor 51 moves at the preset speed two. When the pneumatic motor 51 is in motion, the centrifugal force on the transverse spoiler 5612 is relatively small, and the elastic force of the spiral spring 563 pulls the second support arm 564 to the position close to the first support arm 561, so the angle between the first support arm 561 and the second support arm 564 changes only slightly from the original state. When the pneumatic motor 51 is in a state of alternating cycles of preset speed one and preset speed two, the transverse spoiler 5612 moves from a position close to the stirring shaft 52 to the inner wall of the mixing barrel 2, and then moves from a position close to the inner wall of the mixing barrel 2 cavity to a position close to the stirring shaft 52, and so on. The chlorobenzaldehyde, xylene solvent, ethylene glycol and p-toluenesulfonic acid in the mixing barrel 2 generate a transverse flow under the promotion of the longitudinal spoiler unit 568 and the transverse spoiler 5612. At the same time, when the longitudinal spoiler unit 568 is rotating, the slurry inside the mixing barrel 2 flows into the input pipe section a3 through the trumpet 5611. Since the position of the No. 1 channel 5610 is directly opposite to the impeller 5615, the impeller 5615 rotates rapidly under the push of the slurry, and the turbofan 5616 rotates synchronously while generating an upward suction force. Part of the slurry entering the input pipe section a3 flows to the output pipe section a2 through the throat a1 and flows out through the top of the output pipe section a2. When the slurry flows through the throat a1, a negative pressure lower than the external pressure is formed at this position, and the slurry inside the mixing barrel 2 It is sucked into the throat a1 through the No. 2 channel 5613 and the conducting pipe 5614 and discharged through the top of the longitudinal spoiler unit 568. While the side wall of the transverse spoiler 5612 slides close to the inner wall of the mixing barrel 2, the slurry that is attached to the inner wall of the mixing barrel 2 and is not evenly mixed also enters the conducting pipe 5614 through the No. 2 channel 5613, and then enters the longitudinal spoiler unit 568 for mixing. It should be noted here that the process of cleaning the inner wall of the mixing barrel 2 after the mixing is completed is the same as the process of scraping the inner wall of the mixing barrel 2 by the transverse spoiler 5612, and will not be repeated here.
