[0002] Crystallization kettles are core equipment in chemical, pharmaceutical, and food industries for material crystallization and separation. Their working process involves precipitating solutes from materials and forming crystals through cooling, evaporation, and other methods. However; As disclosed in announcement number CN206809819U, a novel crystallization kettle device includes a crystallization kettle body. The upper end of the crystallization kettle body is provided with a rotary stirring mechanism, and the upper surface of the crystallization kettle body is also provided with a multi-select solvent addition mechanism. By setting the rotary stirring mechanism, the material can be effectively stirred quickly and evenly, and it is not easy to stick together, thereby improving the crystallization efficiency of the material. By setting the multi-select solvent addition mechanism, the crystals to be dissolved are fused with the solution, and can be used directly, which can save process procedures and has strong practicality. However, in the existing technology, during actual operation of the crystallization vessel, the material is prone to accumulate on the inner wall of the vessel, the surface of the stirring paddle and the bottom of the vessel due to temperature gradient, uneven concentration and wall adhesion effect, forming a hard wall layer that is not easy to clean. The wall layer will hinder the heat transfer between the vessel and the material, resulting in a decrease in the accuracy of crystallization temperature control. For example, the comparative patents listed above have this problem. Therefore, this utility model provides a novel ultrasonic anti-fouling crystallizer to solve the problems mentioned above.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-6 The present invention provides the following technical solution: To address the problem in existing crystallizers where materials easily accumulate and form a hardened wall layer on the inner wall, agitator surface, and bottom due to temperature gradients, uneven concentration, and wall adhesion effects, which is difficult to clean and hinders heat transfer between the crystallizer and the material, leading to a decrease in crystallization temperature control accuracy, this solution provides a novel ultrasonic anti-wall-caking crystallizer. The crystallizer comprises a vessel body 1, a fixed support 2, and a vessel lid 3; and an agitation assembly including a drive unit, an agitator rod 7 fixed to the output end of the drive unit, and a stirring rod 7 fixed to the... The outer end of the stirring rod 7 has a scraper 8 that fits against the inner wall of the vessel body 1; the ultrasonic vibration assembly is symmetrically arranged on the left and right sides of the vessel body 1, including an ultrasonic generator 11, an ultrasonic transducer 12 and an ultrasonic vibration rod 13 installed on the outside of the vessel body 1. The ultrasonic generator 11 and the ultrasonic transducer 12 are electrically connected. One end of the ultrasonic vibration rod 13 is connected to the ultrasonic transducer 12, and the other end extends through the vessel body 1 into the interior of the vessel body 1. The outer surface of the ultrasonic vibration rod 13 located inside the vessel body 1 is provided with several spherical protrusions 14. like Figure 1 , Figure 2 , Figure 2 and Figure 4 As shown, the vessel body 1 is placed on the ground via a fixed bracket 2. A heating box 9 is fixedly connected to the outside of the vessel body 1, and a heating element 10 is installed inside the heating box 9. The heating element 10 is turned on by an external controller to heat the inside of the vessel body 1 to a suitable temperature. A vessel lid 3 is fitted onto the upper end of the vessel body 1, and a sealing ring 16 is fitted between the vessel lid 3 and the vessel body 1 to ensure the sealing of the connection. A feeding port 4 is provided at the upper left end of the vessel lid 3, and an air outlet is provided at the right end of the vessel lid 3. The air outlet is connected to a one-way valve 5 installed at the upper right end of the vessel lid 3. The material is added into the interior of the vessel body 1 in an appropriate amount through the feeding port 4. After the material is added, the feeding port 4 is sealed. The stirring motor 6 installed in the middle of the upper part of the vessel cover 3 is started by the external controller. The stirring motor 6 drives the stirring rod 7 and the scraper 8 to rotate inside the vessel body 1, so as to evenly mix the material inside the vessel body 1. At the same time, it can also scrape off the material adhering to the inner wall of the vessel body 1. The upper right end of the vessel cover 3 is provided with an exhaust port, which is connected to a one-way valve 5 to discharge gas, which can balance the pressure inside the vessel body 1 and ensure the safe operation of the equipment. like Figure 5 and Figure 6As shown, by setting up the ultrasonic vibration component, the ultrasonic generator 11 is turned on by the controller. The ultrasonic generator 11 converts electrical energy into high-frequency electrical signals and transmits them to the ultrasonic transducer 12. The ultrasonic transducer 12 converts the high-frequency electrical signals into mechanical vibrations, which are then transmitted to the ultrasonic vibration rod 13 connected to the ultrasonic transducer 12. This allows the ultrasonic vibration rod 13 to transmit mechanical vibrations to the material inside the reactor. The high-frequency vibrations can destroy the adsorption force of solute molecules on the inner wall of the reactor body 1, the scraper 8, and the surface of the heating box 9, effectively preventing the formation of a wall layer. At the same time, the spherical protrusions 14 on the surface of the ultrasonic vibration rod 13 can also enhance the transmission range of the vibration. After the crystallization process is completed, the power is turned on and the discharge valve 15 at the lower end of the reactor body 1 is opened to discharge the crystallized product. In addition, the fasteners include a fixing rod 17 welded to the outer side of the upper end of the vessel body 1 and a fixing cap 18 threaded to the outer surface of the fixing rod 17. By rotating the fixing cap 18 threaded to the outer surface of the fixing rod 17, the fixing cap 18 disengages from the fixing rod 17 and the vessel cover 3, thereby loosening the pressure limit on the vessel cover 3. Then, the vessel cover 3 is pulled upward, and the vessel cover 3 disengages from the vessel body 1 and moves out with the stirring rod 7 and scraper 8, which facilitates thorough cleaning of the interior as well as the stirring rod 7 and scraper 8, avoiding residue.
