[0014] A method of using a loop reactor for the production of hydroxyl acrylates, comprising the following steps:

[0015] Step 1: First, add the material into the reactor body, then open the circulation pipe. The material enters the heat exchanger through the circulation pump and then enters the jet mixer. At this time, the jet mixer transmits the material through the metal spray pipe to the interior of each hollow slide, and sprays the material through the spray head below the hollow slide.

[0016] Step 2: When spraying materials, start the general motor one. The general motor one drives the semi-circular gear to rotate. When the tooth block end of the semi-circular gear meshes with the adjusting gear, the cross support rod drives the hollow slide on the cross mounting rod to rotate intermittently in a circular motion. At the same time, start the winding motor to wind up the rope. The rope drives the hollow slide to move in the groove on the cross mounting rod. The return spring resets the hollow slide, so that the spray head below the hollow slide can spray the material evenly.

[0017] Step 3: During the mixing process, start the drive motor. The drive motor drives the rotating rod, which causes the push rod to move the top rod back and forth inside the limiting tube. As the top rod rises, it impacts one end of the impact column, causing the impact column to move the reactor body upward. The second vibration spring is compressed, and the first vibration spring located inside the limiting tube is stretched. When the top rod moves downward, the first and second vibration springs generate continuous vibration.

[0018] As can be seen from the above, the loop reactor for the production of hydroxyl acrylates provided by the present invention has the beneficial effects of ensuring thorough mixing of materials, resulting in high reaction rate, low side reaction rate, reduced material consumption, and high product quality.

[0038] In a specific application scenario, the material is first added to the reactor body 2, and then the circulation pipe 9 is opened. The material enters the heat exchanger 6 through the circulation pump 8 and then enters the jet mixer 406. At this time, the jet mixer 406 transmits the material through the metal spray pipe 416 to the interior of each hollow slide 410. The material is sprayed through the spray head 417 below the hollow slide 410. When the material is sprayed, the general motor 414 is started, which drives the semi-circular gear 415 to rotate.

The drive motor 403 drives the rotating rod 423, which causes the push rod 425 to drive the top rod 426 to move back and forth inside the limiting tube 427. During the upward movement of the top rod 426, the top rod 426 impacts one end of the impact column 428, which causes the impact column 428 to move the reactor body 2 upward. The second vibration spring 429 is compressed, and the first vibration spring 420 located inside the limiting tube 401 is stretched. When the top rod 426 moves downward, the first vibration spring 420 and the second vibration spring 429 generate continuous vibration, so that the material inside the reactor body 2 is fully mixed and reacts. Through the mixing module 4, the material is fully mixed, resulting in a high reaction rate, low side reaction generation, reduced material consumption, and high product quality.

The bottom side of the reactor body 2 has a collection port, and the collection port is fixedly connected to the discharge pipe 10.

[0042] In specific application scenarios, during the forced circulation of the reaction liquid in the circulating pump 8 and heat exchanger 6, the reaction liquid passes through the collection filter 509 inside the sieve cylinder 1 504. The collection filter 509 collects the impurities generated during the reaction, preventing them from affecting the reaction operation. When the collection filter 509 is filtering the reactants, the general-purpose motor 2 506 is started. The general-purpose motor 2 506 drives the belt 507, which causes the rotating platform 508 to rotate the collection filter 509 inside the sieve cylinder 1 504. The compression spring 512 on the sieve cylinder 2 514 compresses the cleaning brush 513, making the cleaning end of the cleaning brush 513 fully adhere to the inner wall of the collection filter 509, thereby cleaning the inner wall of the collection filter 509 and preventing clogging.

[0043] A method of using a loop reactor for the production of hydroxyl acrylates, comprising the following steps:

[0044] Step 1: First, add the material to the reactor body 2, then open the circulation pipe 9. The material enters the heat exchanger 6 through the circulation pump 8 and then enters the jet mixer 406. At this time, the material is transferred to each hollow slide 410 through the metal spray pipe 416 by the jet mixer 406. The material is sprayed through the spray head 417 below the hollow slide 410.

[0045] Step 2: When spraying materials, start the general motor 414. The general motor 414 drives the semi-circular gear 415 to rotate. When the tooth block end of the semi-circular gear 415 meshes with the adjusting gear 407, the cross support rod 408 drives the hollow slide block 410 on the cross mounting rod 409 to rotate intermittently in a circle. At the same time, start the winding motor 411. The winding motor 411 winds up the rope 413. The rope 413 drives the hollow slide block 410 to move in the groove on the cross mounting rod 409. The return spring 418 resets the hollow slide block 410, so that the spray head 417 below the hollow slide block 410 sprays the materials evenly.

[0046] Step 3: During the mixing process, the drive motor 403 is started. The drive motor 403 drives the rotating rod 423, which causes the push rod 425 to drive the top rod 426 to reciprocate inside the limiting tube 427. During the upward movement of the top rod 426, the top rod 426 impacts one end of the impact column 428, causing the impact column 428 to drive the reactor body 2 to move upward. The second vibration spring 429 is compressed, and the first vibration spring 420 located inside the limiting tube 401 is stretched. When the top rod 426 moves downward, the first vibration spring 420 and the second vibration spring 429 generate continuous vibration.

8. A method of using a loop reactor for the production of hydroxyl acrylates, comprising using the loop reactor for the production of hydroxyl acrylates according to claim 7, characterized in that, Includes the following steps: Step 1: First, add the material to the reactor body (2), then open the circulation pipe (9), and the material enters the heat exchanger (6) through the circulation pump (8) and then enters the jet mixer (406). At this time, the material is transferred to each hollow slide (410) through the metal spray pipe (416) by the jet mixer (406), and the material is sprayed through the spray head (417) below the hollow slide (410). Step 2: When spraying materials, start the general motor (414). The general motor (414) drives the semi-circular gear (415) to rotate. When the tooth block end of the semi-circular gear (415) meshes with the adjusting gear (407), the cross support rod (408) drives the hollow slide (410) on the cross mounting rod (409) to rotate intermittently in a circle. At the same time, start the winding motor (411). The winding motor (411) winds up the rope (413). The rope (413) drives the hollow slide (410) to move in the groove on the cross mounting rod (409). The reset spring (418) resets the hollow slide (410), so that the spray head (417) below the hollow slide (410) sprays the materials evenly. Step 3: During the mixing process, start the drive motor (403). The drive motor (403) drives the rotating rod (423) so that the push rod (425) drives the top rod (426) to move back and forth inside the limiting tube (427). During the upward movement of the top rod (426), the top rod (426) impacts one end of the impact column (428), causing the impact column (428) to drive the reactor body (2) to move upward. The second vibration spring (429) is squeezed, and the first vibration spring (420) located inside the limiting tube (401) is stretched. When the top rod (426) moves downward, the first vibration spring (420) and the second vibration spring (429) generate continuous vibration.
