It is a pressure vessel used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples of reaction vessels include reactors, reaction pots, decomposition pots, and polymerization kettles.

[0003] Chinese patent disclosure (CN111715164B) discloses a reaction vessel for preparing a polyolefin catalyst. The reaction vessel includes a vessel body, a stirring mechanism, a filtration mechanism, and a spraying mechanism. The vessel body has a reaction chamber for material reaction.

The stirring mechanism... The mechanism is configured to stir the material and push the solid material to the solid material outlet; the spraying mechanism is configured to spray and wash the solid material.

The materials undergo a reaction process in the reaction chamber of the reactor. During the reaction, the stirring mechanism continuously stirs the materials to ensure a more complete and effective reaction. After the reaction, the materials form solid and liquid components. The liquid component is separated from the solid component by the filter plate and flows to the liquid outlet. The solid component is carried by the filter plate and washed by the spray mechanism. After washing and drying, the solid component is then pushed to the solid outlet by the stirring mechanism, completing the preparation of the polyolefin catalyst. Although current reactors are equipped with stirring mechanisms, the overall functionality of these mechanisms is not high. When the stirring mechanism is used, it cannot effectively improve the stirring effect of the materials, thus affecting the use effect of the reactor. For some solid particulate reactants, it cannot improve their dissolution rate, resulting in poor overall performance. To solve these problems, there is an urgent need for new high-performance chemical reactors. Summary of the Invention

Specifically, for some solid particulate reactants, the dissolution rate cannot be improved, resulting in poor overall performance. Therefore, this invention proposes a new type of high-performance chemical reactor.

[0009] The grinding inner cylinder is fixedly installed on the outside of the mounting spindle via a connecting rod. The grinding inner cylinder has several pores inside, and there is a gap between the grinding inner cylinder and the inner wall of the vessel body.

[0010] As a further description of the above technical solution:

[0011] The grinding cylinder is equipped with a built-in stirring assembly, which includes a mounting shaft bracket. The mounting shaft bracket is fixedly installed on the inner wall of the grinding cylinder, and a built-in stirring shaft is rotatably installed inside the mounting shaft bracket.

[0012] As a further description of the above technical solution:

[0013] The built-in stirring shaft is externally fixedly equipped with built-in stirring blades. Two built-in stirring blades are symmetrically arranged about the longitudinal central axis of the built-in stirring shaft. A meshing gear is externally fixedly installed at the upper end of the built-in stirring shaft.

[0014] As a further description of the above technical solution:

[0015] A dredging bottom shaft is fixedly installed at the bottom end of the built-in stirring shaft, and a discharge pipe is fixedly installed on the bottom surface of the vessel body. A liquid control valve is provided at the bottom of the discharge pipe, and the dredging bottom shaft is located inside the discharge pipe.

[0016] As a further description of the above technical solution:

[0017] The built-in stirring blade has an internal mounting groove, and a guide rail is fixedly mounted on the inner wall of the mounting groove. A built-in scraper is slidably mounted on the guide rail, and a built-in spring is fixedly mounted on one end of the built-in scraper.

[0018] As a further description of the above technical solution:

[0019] One end of the built-in spring is fixedly connected to the inner wall of the mounting groove. One end of the built-in scraper is located outside the built-in stirring blade. One end of the built-in scraper is in close contact with and squeezed against the inner wall of the grinding cylinder. An internal gear ring is fixedly installed inside the reactor body. The internal gear ring and the meshing gear are meshed with each other.

[0020] As a further description of the above technical solution:

[0021] A steam collection assembly is provided on the side wall of the reactor body. The steam collection assembly is used to collect and condense steam during the reaction process. The steam collection assembly includes a steam collection box, which is fixedly installed on the side wall of the reactor body by a mounting bracket.

[0022] As a further description of the above technical solution:

The water guide pipe is sealed and fixedly connected to the water return hole provided on the side wall of the vessel.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, a grinding and stirring mechanism is provided. When the raw materials undergo a chemical reaction, the reaction materials are placed into the reactor body through the feeding pipe. The heating element is turned on to raise the temperature inside the equipment. At this time, the drive motor is turned on, and the drive motor controls the grinding and stirring mechanism to rotate. When the grinding and stirring mechanism rotates, it can drive the internal built-in stirring component to rotate. Due to the meshing connection between the meshing gear of the built-in stirring component and the internal gear ring inside the equipment, the built-in stirring shaft and the built-in stirring blade can rotate synchronously during the rotation of the built-in stirring component. This can effectively move and stir the raw materials placed in the equipment. At the same time, some solid raw material particles introduced into the equipment can flow with the fluid to the gap between the grinding inner cylinder and the reactor body, and be effectively ground by the grinding inner cylinder to reduce the diameter of the solid particles and make them easier to dissolve. Through this design, not only can the uniform stirring effect of the introduced raw materials be achieved, but also the synchronous grinding treatment of the introduced solid particles can be achieved, thereby improving the dissolution rate of the raw materials and effectively improving the overall functionality of the equipment and the use effect of the equipment.

[0026] 2. In this invention, a bottom shaft for unblocking is provided on the grinding and stirring mechanism. When the grinding and stirring mechanism rotates, the bottom shaft for unblocking can rotate synchronously. Since the bottom shaft for unblocking is inside the discharge pipe, it can continuously stir and unblock the discharge pipe. When the reaction in the reactor is completed and discharge is required, the valve can be opened directly, and the raw material can be quickly discharged through the discharge pipe. At the same time, when the grinding and stirring mechanism rotates, the built-in scraper can continuously scrape off the raw material adhering to the inner wall of the grinding cylinder, ensuring the cleanliness of the grinding cylinder. This invention can realize the integrated function of stirring, grinding and unblocking in the equipment, and improve the equipment's performance.

[0027] 3. In this invention, a steam collection component is provided, and a wind turbine blade is installed on the grinding and stirring mechanism. When the raw materials react in the stirring vessel, the water in the raw materials will evaporate due to the high temperature. The evaporated water vapor will rise slowly and accumulate in the upper part of the equipment. At this time, due to the rotational stirring effect of the grinding and stirring mechanism, the wind turbine blade can be driven to rotate simultaneously. The wind turbine blade increases the flow rate of the steam. The steam can enter the steam collection box through the steam collection pipe. After the steam is condensed by the serpentine condenser, it becomes droplets and flows back into the equipment. Through this design, the water vapor generated in the equipment can be quickly turbulent, so that the water vapor can enter the steam collection component for condensation in a high efficiency. This effectively replenishes the water vapor evaporated during the raw material reaction, thereby improving the reaction effect of the raw materials. Attached Figure Description

Detailed Implementation

[0037] Please see Figure 1-7 The present invention provides a technical solution: a novel high-performance chemical reactor, comprising a reactor body 2, a drive motor 1 fixedly installed on the top surface of the reactor body 2, a feeding pipe 3 fixedly installed on the outer surface of the reactor body 2, an electric heating tube embedded in the shell cavity of the reactor body 2, and a foot 4 fixedly installed on the bottom surface of the reactor body 2. A grinding and stirring mechanism 6 is provided at one end of the output shaft of the drive motor 1, and the grinding and stirring mechanism 6 is used for stable grinding and stirring of raw materials.

[0038] The grinding and stirring mechanism 6 includes a mounting shaft 63, on the outside of which wind turbine blades 62 are fixedly mounted. The inside of the wind turbine blades 62 is provided with a circular groove, and a wind turbine fan is provided in the circular groove. A wind net 65 is provided on the outside of the wind turbine fan. A grinding inner cylinder 61 is fixedly mounted on the outside of the mounting shaft 63 through a connecting rod. The inside of the grinding inner cylinder 61 is provided with several holes, and there is a gap between the grinding inner cylinder 61 and the inner wall of the vessel body 2.

[0039] The grinding inner cylinder 61 is provided with a built-in stirring assembly 64. The built-in stirring assembly 64 includes a mounting shaft bracket 642, which is fixedly installed on the inner wall of the grinding inner cylinder 61. A built-in stirring shaft 643 is rotatably installed inside the mounting shaft bracket 642. Built-in stirring blades 644 are fixedly installed on the outside of the built-in stirring shaft 643. Two built-in stirring blades 644 are symmetrically arranged about the longitudinal central axis of the built-in stirring shaft 643. A meshing gear 641 is fixedly installed on the upper end of the built-in stirring shaft 643.

[0040] The specific implementation method is as follows: When the raw materials are subjected to a chemical reaction, the reaction raw materials are placed into the reactor body 2 through the feeding pipe 3, the electric heating tube is turned on to raise the temperature inside the equipment, and the drive motor 1 is turned on. The drive motor 1 controls the grinding and stirring mechanism 6 to rotate. When the grinding and stirring mechanism 6 rotates, it can drive the internal built-in stirring component 64 to rotate. Due to the meshing connection between the meshing gear 641 of the built-in stirring component 64 and the internal gear ring 7 inside the equipment, the built-in stirring shaft 643 and the built-in stirring blade 644 can rotate synchronously during the rotation of the built-in stirring component 64. This can effectively move and stir the raw materials placed in the equipment. At the same time, some solid raw material particles introduced into the equipment can flow with the fluid to the gap between the grinding inner cylinder 61 and the reactor body 2, and be effectively ground by the grinding inner cylinder 61 to reduce the diameter of the solid particles and make them easier to dissolve.

[0041] This design not only achieves uniform mixing of the introduced raw materials but also enables simultaneous grinding of the introduced solid particles, thereby increasing the dissolution rate of the raw materials and effectively enhancing the overall functionality and performance of the equipment.

[0042] A dredging bottom shaft 645 is fixedly installed at the bottom end of the built-in stirring shaft 643. A discharge pipe 5 is fixedly installed on the bottom surface of the vessel body 2. A liquid control valve is provided at the bottom of the discharge pipe 5. The dredging bottom shaft 645 is located inside the discharge pipe 5. An installation groove 646 is provided inside the built-in stirring blade 644. A guide rail is fixedly installed on the inner wall of the installation groove 646. A built-in scraper 647 is slidably installed on the guide rail. A built-in spring 648 is fixedly installed at one end of the built-in scraper 647. One end of the built-in spring 648 is fixedly connected to one side of the inner wall of the installation groove 646. One end of the built-in scraper 647 is located outside the built-in stirring blade 644. One end of the built-in scraper 647 is in close contact with and squeezes the inner wall of the grinding inner cylinder 61. An internal gear ring 7 is fixedly installed inside the vessel body 2. The internal gear ring 7 is meshed with the meshing gear 641.

[0043] The specific implementation method is as follows: When the grinding and stirring mechanism 6 rotates, the unblocking bottom shaft 645 can be driven to rotate synchronously. Since the unblocking bottom shaft 645 is inside the discharge pipe 5, the unblocking bottom shaft 645 can continuously stir and unblock the discharge pipe 5. When the reaction in the reactor is completed and the material needs to be discharged, the valve can be opened directly and the raw material can be quickly discharged through the discharge pipe 5. At the same time, when the grinding and stirring mechanism 6 rotates, the built-in scraper 647 can continuously scrape off the raw material adhering to the inner wall of the grinding inner cylinder 61 to ensure the cleanliness of the grinding inner cylinder 61.

[0044] This design enables the equipment to integrate mixing, grinding, and unclogging functions, thereby improving the equipment's performance.

[0045] A steam collection assembly 8 is provided on the side wall of the vessel body 2. The steam collection assembly 8 is used to collect and condense steam during the reaction process. The steam collection assembly 8 includes a steam collection box 82, which is fixedly installed on the side wall of the vessel body 2 by a mounting bracket. A steam collection pipe 81 is fixedly installed on the top of the steam collection box 82. One end of the steam collection pipe 81 is sealed and fixedly connected to a vent provided on the side wall of the vessel body 2. A serpentine condenser is fixedly installed inside the steam collection box 82. A water guide pipe is fixedly installed at the bottom of the steam collection box 82 and is sealed and fixedly connected to a water return hole provided on the side wall of the vessel body 2.

[0046] The specific implementation method is as follows: When the raw material reaction is carried out in the stirring tank, the water in the raw material will be evaporated due to the high temperature. The evaporated water vapor will rise slowly and accumulate in the upper part of the equipment. At this time, due to the rotation stirring effect of the grinding and stirring mechanism 6, the wind turbine blades 62 can be driven to rotate synchronously. The wind turbine blades 62 thereby increase the flow rate of steam. The steam can enter the steam collection box 82 through the steam collection pipe 81. After the steam is condensed by the serpentine condenser, it becomes liquid droplets and flows back into the equipment.

[0047] This design effectively turbulently generates water vapor within the equipment, allowing it to efficiently enter the steam collection component 8 for condensation. This effectively replenishes the water vapor evaporated during the raw material reaction, thereby enhancing the reaction efficiency of the raw materials.

[0048] Working Principle: When the raw materials undergo a chemical reaction, the reactants are placed into the reactor body 2 through the feeding pipe 3. The heating element is turned on to raise the temperature inside the equipment. At this time, the drive motor 1 is turned on, which controls the grinding and stirring mechanism 6 to rotate. When the grinding and stirring mechanism 6 rotates, it drives the internal built-in stirring component 64 to rotate. Due to the meshing connection between the meshing gear 641 of the built-in stirring component 64 and the internal gear ring 7 inside the equipment, the built-in stirring shaft 643 and the built-in stirring blades 644 can rotate synchronously during the rotation of the built-in stirring component 64. This effectively moves and stirs the raw materials placed in the equipment. At the same time, some solid raw material particles introduced into the equipment can flow with the fluid to the gap between the grinding inner cylinder 61 and the reactor body 2, where they are effectively ground by the grinding inner cylinder 61 to reduce the diameter of the solid particles and make them easier to dissolve. When the grinding and stirring mechanism 6 rotates, it can synchronously move and stir the raw materials inside the equipment. The bottom shaft 645 rotates synchronously. Since the bottom shaft 645 is inside the discharge pipe 5, it can continuously stir and unclog the discharge pipe 5. After the reaction in the reactor is completed, when it is necessary to discharge, the valve can be opened directly, and the raw material can be quickly discharged through the discharge pipe 5. At the same time, when the grinding and stirring mechanism 6 rotates, the built-in scraper 647 can continuously scrape off the raw material adhering to the inner wall of the grinding inner cylinder 61, ensuring the cleanliness of the grinding inner cylinder 61. When the raw material reacts in the stirring tank, the moisture in the raw material will evaporate due to the high temperature. The evaporated water vapor will rise slowly and accumulate in the upper part of the equipment. At this time, due to the stirring effect of the rotation of the grinding and stirring mechanism 6, the wind turbine blades 62 can be driven to rotate synchronously. The wind turbine blades 62 can increase the flow rate of steam. The steam can enter the steam collection box 82 through the steam collection pipe 81. After the steam is condensed by the serpentine condenser, it becomes droplets and flows back into the equipment.
