Description

Technical Field

[0001] The utility model relates to the technical field of crystallization kettles, in particular to a 4,4-bischloromethylbiphenyl crystallization kettle. Background Art

[0002] 4,4-Bischloromethylbiphenyl is an organochlorine compound, commonly used in the production of dyes, pigments and other chemical products. In the chemical industry, the crystallization kettle is an important equipment used in the crystallization process of substances, which can realize the synthesis and purification of 4,4-Bischloromethylbiphenyl. Stirring can make the reactants fully mixed in the crystallization kettle, ensuring uniform contact between the solvent and the reactants, thereby improving the crystallization efficiency.

[0003] In the traditional crystallization process of 4,4-bischloromethylbiphenyl, stirring in the crystallization kettle is a very critical step because it helps to evenly mix the reactants, improve crystallization efficiency, and prevent crystal agglomeration. The crystallization kettle is usually equipped with an agitator, which can be an anchor agitator, a frame agitator, or a propeller agitator. These agitators are driven by a motor and can generate sufficient shear force in the crystallization kettle to keep the solvent and reactants evenly mixed. The anchor agitator is the most commonly used type. It has several arms with stirring paddles at the end of the arms that can rotate in the kettle to drive the liquid flow.

[0004] The above-mentioned traditional stirring is mostly carried out by driving a single stirring blade or other structure by a motor to stir the crystals. Such a setting can only continuously stir the middle part of the storage kettle, resulting in difficulty in obtaining good mixing at the periphery of the storage kettle, resulting in uneven distribution of components in the solution during the crystallization process, thereby causing inconsistency in crystal size and crystal morphology, affecting product quality and purity.

[0007] Furthermore, the auxiliary component includes a ball, the ball is arranged at the bottom of the sliding rod, and the outer wall of the ball is slidably connected to the inner wall of the support plate.

[0008] Furthermore, a feed pipe is fixedly connected to the interior of the storage kettle, and a valve is fixedly connected to the outer wall of the feed pipe.

[0009] Furthermore, a feeding plate is fixedly connected to the top of the feeding pipe, and a discharging plate is fixedly connected to the bottom of the storage kettle.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 2The utility model provides an embodiment: a 4,4-bischloromethylbiphenyl crystallization kettle, comprising a storage kettle 1, a sealing top cover 2 is fixedly connected to the top of the storage kettle 1, a motor 3 is fixedly connected to the upper surface of the sealing top cover 2, a rotating plate 4 is fixedly connected to the output end of the motor 3, a support plate 5 is fixedly connected to the bottom of the storage kettle 1, a support column 6 is fixedly connected to the upper surface of the support plate 5, a gear 7 is fixedly connected to the top of the support column 6, a gear 2 8 is rotatably connected to the inside of the rotating plate 4, the gear 2 8 is meshed with the gear 1 7, a sliding rod 9 is fixedly connected to the inside of the gear 2 8, an auxiliary component is arranged at the bottom of the sliding rod 9, a rotating shaft 10 is fixedly connected to the outer wall of the sliding rod 9, a stirring rod 11 is rotatably connected to the inside of the rotating shaft 10, and the auxiliary component comprises a ball 12, the ball 12 is arranged at the bottom of the sliding rod 9, and the outer wall of the ball 12 is slidably connected to the inner wall of the support plate 5;

[0024] Specifically, first, the output end of the motor 1 3 drives the rotating plate 4 to rotate inside the sealing top cover 2, and the linkage between the gear 2 8 and the rotating plate 4 further drives the sliding rod 9 to rotate inside the storage kettle 1. In this process, the meshing relationship between the gear 1 7 and the gear 2 8 plays a key role, so that the gear 2 8 rotates around the gear 1 7 while also rotating on its own, and then is transmitted to the stirring rod 11 through the sliding rod 9, so that the stirring rod 11 rotates inside the storage kettle 1 while also rotating with itself and the sliding rod 9 as the center of the circle, so that the stirring rod 11 can more comprehensively cover the internal space of the storage kettle 1, thereby achieving sufficient stirring of the crystallized material. In addition, the rotation of the sliding rod 9 will also drive the ball 12 at the bottom to slide on the inner wall of the support plate 5, which not only provides a smooth guide for the rotation of the sliding rod 9 and ensures the stable progress of the stirring process, but also reduces the friction resistance that may occur during the stirring process, thereby improving the operating efficiency and service life of the equipment, so that the 4,4-bischloromethylbiphenyl crystallization kettle can provide efficient and uniform stirring effect for crystallization production.

[0025] Reference Figure 1 and Figure 3 A feed pipe 14 is fixedly connected to the inside of the storage kettle 1, a valve 16 is fixedly connected to the outer wall of the feed pipe 14, a feed plate 15 is fixedly connected to the top of the feed pipe 14, a discharge plate 13 is fixedly connected to the bottom of the storage kettle 1, a support 17 is fixedly connected to the lower surface of the discharge plate 13, a discharge pipe 18 is fixedly connected to the bottom of the discharge plate 13, a support 19 is fixedly connected to the outer wall of the discharge pipe 18, the support 19 is arranged below the discharge plate 13, a motor 20 is fixedly connected to the outer wall of the discharge pipe 18, an auger blade 21 is fixedly connected to the output end of the motor 20, and the outer wall of the auger blade 21 is rotatably connected to the inner wall of the discharge pipe 18;

[0026] Specifically, first, the crystals are accurately transported to the interior of the storage kettle 1 through the feed plate 15 and the feed pipe 14. In this step, the valve 16 is responsible for controlling the switch of the crystals entering the storage kettle 1, ensuring the accuracy and controllability of material transportation. Next, after being stirred inside the storage kettle 1, the crystallized material is transported to the interior of the discharge pipe 18 through the discharge plate 13, and then the output end of the motor 20 drives the auger blade 21 to rotate inside the discharge pipe 18. The auger blade 21 enables the crystallized material in the discharge pipe 18 to be effectively pushed, thereby realizing uniform transportation of the crystals, which not only ensures the uniform distribution of the crystallized material during the transportation process, but also avoids the possibility of material blockage. In addition, by adjusting the rotation speed of the motor 20, the crystal transportation speed can be accurately controlled, so that the production process can be adjusted according to actual needs, thereby improving the adaptability and efficiency of the production line.

[0027] Working principle: when the 4,4-bischloromethylbiphenyl crystallization kettle is needed, first, the output end of the motor 3 is used to drive the rotating plate 4 to rotate inside the sealing top cover 2, thereby driving the sliding rod 9 to rotate inside the storage kettle 1 through the gear 2 8. In this process, due to the meshing of the gear 1 7 and the gear 2 8, the gear 2 8 rotates around the gear 7 while also rotating on its own, thereby driving the stirring rod 11 to rotate inside the storage kettle 1 through the sliding rod 9, while making the stirring rod 11 and the sliding rod 9 rotate as the center of the circle, thereby achieving sufficient stirring of the crystals. In this process, the rotation of the sliding rod 9 will cause the ball 12 at the bottom to slide on the inner wall of the support plate 5, guide the rotation of the sliding rod 9, and achieve stirring. Then the crystals are transported to the inside of the storage kettle 1 through the feed plate 15 and the feed pipe 14. This process is controlled by the valve 16. The switch is then controlled, and the stirred material is then transported to the inside of the discharge pipe 18 through the discharge plate 13. Then, the auger blade 21 is driven to rotate inside the discharge pipe 18 through the output end of the motor 20, thereby evenly transporting the crystals.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
