Description

Technical Field

[0001] The invention relates to the technical field of hydroxylamine hydrochloride preparation, in particular to a self-cleaning solvent-free reaction device for hydroxylamine hydrochloride ammoximation. Background Art

[0002] Hydroxylamine hydrochloride plays a key role in many fields. It is not only widely used as a reducing agent and developer, but also plays an important role in organic synthesis. It can be used to efficiently prepare oxime compounds. In addition, it is also a key raw material for the synthesis of a series of drugs and pesticides, such as the anticancer drug hydroxyurea, the sulfonamide drug sulfamethoxazole and the pesticide methomyl. In addition, hydroxylamine hydrochloride has different roles in the fields of electroanalysis, synthetic rubber industry, synthetic dye industry and analytical chemistry. The ammoximation process is an important chemical reaction process. It has a wide range of applications in many industrial fields. Ammoximation refers to the process of reacting ammonia with similar compounds to generate corresponding ammoximation compounds. In this process, ammonia reacts with similar compounds as a nitrogen source to form ammoximation compounds. In the preparation process of hydroxylamine hydrochloride, it is necessary to use the reaction steps of the ammoximation process. In the actual preparation process, it is necessary to use the reactor.

[0022] In order to increase the stability of the activities of the two lifting blocks 9 and limit the movement tendency of the two lifting blocks 9, in this method, two strip holes are opened on the support frame 1, and limit blocks are fixedly installed on the sides of the two lifting blocks 9 away from each other. The two limit blocks are respectively slidably installed in the two strip holes, and positioning blocks are fixedly sleeved on the two threaded rods 5. The two positioning blocks facilitate determining the highest position of the two lifting blocks 9 when they move up.

[0023] In order to facilitate heat dissipation and ventilation of various components on the kettle body top cover 4 and reduce the wear of the circular set block 16 during rotation, in this method, four connecting holes are opened on the fixed frame 15, and a plurality of rolling balls are inlaid on the inner wall of the circular set block 16, and the plurality of rolling balls are in contact with the fixed frame 15.

[0025] In this embodiment In the initial state, the reactor 3 and the kettle body top cover 4 are in contact with each other and fit together, so that the reactor 3 constitutes a closed space. When the reactor 3 is used up and the interior needs to be cleaned, first ensure that the reactor 3 is in a closed state, then start the waterproof motor 6, the output shaft of the waterproof motor 6 will drive the threaded rod 5 fixedly connected thereto to rotate, and the threaded rod 5 drives the corresponding synchronous wheel 7. Under the cooperation of the two synchronous wheels 7 and a synchronous belt 8, the two threaded rods 5 will rotate at the same time, and the two lifting blocks 9 will move upward on the two threaded rods 5 at the same time. The two lifting blocks 9 drive the kettle body top cover 4 to move upward through the two adapter blocks 10, and the kettle body top cover 4 will gradually move away from the reactor 3 until the two lifting blocks 9 contact the two positioning blocks, and the waterproof motor 6 will automatically close. At this time, the kettle body top cover 4 has been adjusted to a predetermined height.

[0026] Then start the waterproof motor 12, which drives the corresponding circular gear 14 through the adapter shaft 13. With the cooperation of the two circular gears 14, the kettle top cover 4 will rotate 180 degrees with the two adapter blocks 10 as the center. The rotating shaft on the kettle top cover 4 that was originally facing vertically downward will be adjusted to face vertically upward, and the scraper plate 44 that was originally located above will be rotated to face downward. After the position is swapped, start the waterproof motor 6 again, and the output shaft of the waterproof motor 6 will rotate in the opposite direction, driving the kettle top cover 4 to gradually move downward, and the scraper plate 44 and other components that were originally located above the kettle top cover 4 will gradually slide into the reactor 3 until the bottom of the anti-leakage plate 46 contacts the top of the reactor 3, and the waterproof motor 6 will be closed again. At this time, the reactor 3 will be in a relatively closed state again.

[0027] Then the waterproof motor 4 34 is started, and the output shaft of the waterproof motor 4 34 will drive the circular block 32 fixed thereto, and under the cooperation of the two circular blocks 32, the water delivery pipe 3 33 is driven to rotate with the two circular blocks 32 as the center of the circle. After the output shaft of the waterproof motor 4 34 drives the water delivery pipe 3 33 to rotate to a predetermined position, it will start to rotate in the opposite direction, and so on, which can drive the high-pressure nozzle 35 to swing up and down back and forth, so that the high-pressure nozzle 35 can be directed to different positions, and then the cleaning water is sprayed through an external water source. Water or cleaning liquid is introduced into hose 1 26, and then flows through water supply pipe 1 25 and water supply pipe 2 28 into hose 2 29, and then passes through water supply pipe 3 33, and finally sprayed outward through high-pressure nozzle 35. The high-pressure nozzle 35 swinging up and down can spray clean water or cleaning liquid to various places on the inner wall of the reactor 3, complete the flushing of the inner wall of the reactor 3, so that some of the stains sticking on the inner wall of the reactor 3 can be flushed down, and at the same time, stubborn stains are softened, which is convenient for the subsequent cleaning of the stubborn stains.

[0028] The sewage mixed with impurities will be discharged outward through the discharge port at the bottom of the reactor 3. After the high-pressure nozzle 35 sprays for a period of time, the waterproof motor 5 39 is started again. The output shaft of the waterproof motor 5 39 drives the threaded rod 2 38 fixed thereto. During the rotation of the threaded rod 2 38, the moving block 40 will move on the threaded rod 2 38 and the annular block 27, and move between the moving blocks 40 toward the direction of the receiving plate 36. During the movement of the moving block 40, the articulated rod 41 will generate a driving force on the scraper plate 44, and the scraper plate 44 will gradually move toward the inner wall of the reactor 3. The scraper plate 44, which was originally in an inclined state and in a contracted state, is gradually adjusted to a vertical state, and the side of the scraper plate 44 will gradually contact the inner wall of the reactor 3, and then the waterproof motor 5 39 will automatically close.

[0029] Then the waterproof motor 3 20 is started again, and the output shaft of the waterproof motor 3 20 drives the adapter shaft 2 21 to rotate. The adapter shaft 21 drives the circular set block 16 to rotate on the fixed frame 15 through the cooperation of the two circular gears 2 22. The receiving block 18 is driven by the circular set block 16 to generate rotational contact with the annular block 17. The circular set block 16 drives the scraper plate 44 to rotate together through the rectangular block 1 43. During the rotation of the scraper plate 44, impurities on the inner wall of the reactor 3 are scraped off, thereby completing the cleaning of the inside of the reactor 3. During the cleaning of the inside of the reactor 3, the inner wall of the reactor body top cover 4 and the original parts fixed on the reactor body top cover 4 will be exposed outside the reactor 3. At this time, the reactor body top cover 4 and the mounting components on the reactor body top cover 4 can be cleaned. After the cleaning work is completed, the position of the reactor body top cover 4 can be restored by starting the waterproof motor 1 6 and the waterproof motor 2 12, and the entire cleaning work is completed.

[0030] Compared with the related art, the self-cleaning solvent-free reaction device for hydroxylamine hydrochloride ammoximation provided by the present invention has the following beneficial effects: In the present invention, the reactor 3 is separated from the reactor body top cover 4, and the waterproof motor 1 is driven to ensure the sealing between the reactor 3 and the reactor body top cover 4, while driving the reactor body top cover 4 to move upward away from the reactor 3, and the reactor body top cover 4 is turned around to make the structure of the reactor body top cover 4 originally hidden inside the reactor 3 fully exposed, so that there is enough operating space for cleaning, and the cleaning efficiency is guaranteed. Through the coordinated driving of the waterproof motor 1 6 and the waterproof motor 2 12, the cleaning mechanism located on the top of the reactor body top cover 4 can be moved to the inside of the reactor 3, and the inner wall of the reactor 3 can be automatically scraped and rinsed, so that the inside of the reactor 3 can be automatically cleaned to the greatest extent, which is more time-saving and labor-saving than the common cleaning method, and can effectively clean various places in the reactor 3, reducing the residual impurities.

The two sealing gaskets are in contact with the interfaces on the reactor 3 and the reactor body top cover 4.

[0035] In order to limit the movement tendency of the two connecting rods 50 and at the same time limit the movement range of the two threaded rods three 49 to prevent the two threaded rods three 49 from falling off the threaded sleeve 48, in this method, the two connecting rods 50 are fixedly installed with transverse rods on the side close to each other, and the two transverse rods are respectively slidably connected to the two support rods 47, and the ends of the two transverse rods close to each other are fixedly installed with anti-falling blocks, and the two connecting rods 50 and the two connecting blocks 51 are fixedly installed with reinforcement rods, and the four reinforcement rods are respectively fixedly connected to the two arc-shaped sleeve blocks 52.

The sealing gaskets installed on the two arc-shaped sleeve blocks 52 can strengthen the sealing effect between the reactor 3 and the reactor body top cover 4. When the reactor 3 is used up and needs to be cleaned, the threaded sleeve 48 is first rotated, and the two threaded rods 3 49 in the threaded sleeve 48 will move outward at the same time, and the two threaded rods 3 49 drive the two connecting rods 50, and the two connecting rods 50 drive the two connecting blocks 51 and the two transverse rods. At the same time, the two arc-shaped sleeve blocks 52 will gradually slide down from the interface between the reactor 3 and the reactor body top cover 4, contact the restriction on the interface between the reactor 3 and the reactor body top cover 4, and then adjust the position of the reactor body top cover 4 according to the above operation.

[0037] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
