Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of evaporation crystallization devices, and in particular relates to a high-efficiency anti-clogging evaporation crystallization device. Background Technology
[0002] In the production processes of many industries such as chemical, pharmaceutical, and food, evaporation crystallization equipment plays a crucial role. Its core purpose is to evaporate the solvent in the solution, allowing the solute to reach a supersaturated state and crystallize out, thereby achieving the separation and purification of substances. In the entire evaporation crystallization system, the evaporator is undoubtedly the most critical component. As the main site of solution evaporation, it directly affects the efficiency and quality of evaporation crystallization, and is related to whether the entire production process can operate stably and efficiently.
[0003] Some existing evaporators may experience uneven mixing of raw materials during use, resulting in significant local concentration differences in the solution. In high-concentration areas, the solute crystallizes prematurely, which not only easily adheres to the inner wall of the evaporator, causing blockages and hindering normal equipment operation, but also leads to inconsistent crystal particle size, affecting product quality. Meanwhile, the evaporation efficiency in low-concentration areas is low, slowing down the overall production progress. Utility Model Content

The right end of the rotating shaft extends to the inner wall of the right side of the evaporator and is rotatably connected to the evaporator. Several scrapers are fixedly connected to the rotating shaft. The scrapers are slidably connected to the inner wall of the evaporator. Several stirring rods are fixedly connected between the scrapers and the evaporator. The vibration mechanism includes a housing fixedly connected to the right side of the evaporator.
[0008] Furthermore, a feed inlet is fixedly connected to the outer wall of the evaporator, a discharge pipe is fixedly connected to the outer wall of the evaporator, and a branch pipe is fixedly connected to the outer wall of the discharge pipe.
[0009] Furthermore, an electric push rod is fixedly connected to the right end of the discharge pipe.

A sealing plug is fixedly connected to the output shaft of the electric push rod. The sealing plug is slidably connected to the inner wall of the discharge pipe. A transfer plate 313 is fixedly connected to the outer wall of the discharge pipe 26.
[0010] Furthermore, a second motor is fixedly connected to the right side of the housing, and the output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling. The left end of the second rotating shaft extends into the interior of the housing and is rotatably connected to the housing.

[0015] This utility model has the following beneficial effects:
[0016] 1. By setting up a mixing mechanism, starting motor one drives rotating shaft one, which in turn drives the scraper and stirring rod to rotate. The mixing mechanism mixes and stirs the raw materials inside the evaporator, effectively promoting uniform distribution of the raw materials within the evaporator. This prevents excessively high local concentrations from causing premature crystallization and precipitation of the raw materials, which then adheres to the inner wall of the evaporator, reducing the risk of blockage. It also ensures uniform temperature of the raw materials, preventing excessive concentration and crystallization in the heating zone due to local overheating, thus avoiding blockage. At the same time, stirring promotes good flow of the solution, accelerates solvent evaporation, reduces the deposition time of solute on the wall, ensures the normal operation of all components within the evaporator, maintains the high efficiency and stability of the evaporation and crystallization process, and greatly improves the overall operating performance and anti-blocking capability of the equipment.
[0017] 2. By setting up a vibration mechanism and starting motor two, motor two drives shaft two to rotate. When shaft two rotates, it drives half gear to rotate. When half gear rotates, it drives rack to move. When rack moves, it drives moving rod to move. When moving rod moves, it drives vibrating plate to move and spring to contract. The vibration mechanism vibrates the feeding area, effectively preventing material from accumulating, bridging, and blocking inside the pipe. It breaks down the friction and adhesion between materials, keeping them loose and allowing them to slide smoothly. This ensures uniform feeding and prevents uneven feeding speed caused by material clumping and adhesion, which could affect the stability and continuity of subsequent processes. At the same time, vibration can clean the material adhering to the pipe wall in time, reducing the risk of material residue and deterioration, ensuring the cleanliness of the feeding pipe, extending its service life, and allowing the entire production process to operate efficiently and reliably due to stable feeding, reducing equipment failure and maintenance costs.

[0030] A specific application of this embodiment is as follows: When using the device, the raw material to be evaporated and crystallized is introduced into the evaporator 1 through the feed inlet 25. The evaporator 1 has a heating function, thereby heating the raw material for evaporation and crystallization. At this time, the motor 21 is started, and the motor 21 drives the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, it drives the scraper 23 to rotate and the stirring rod 24 to rotate. The stirring rod 24 then mixes and stirs the raw material, thereby creating a turbulent flow state in the evaporator 1, increasing the contact frequency and area between the raw material and the heating surface, thereby improving the evaporation efficiency and crystallization efficiency. At the same time, the scraper 23 also... The inner wall of evaporator 1 is cleaned and scraped to prevent crystals from accumulating on the wall and causing blockage. After the raw material crystallizes, the electric push rod 28 is activated. The electric push rod 28 moves the sealing plug 29 to the position between the branch pipe 27 and the electric push rod 28, so that the crystals in evaporator 1 can enter the branch pipe 27 through the discharge pipe 26 and finally be discharged. After the crystals are discharged, the electric push rod 28 is activated again, so that the electric push rod 28 moves the sealing plug 29 back to the side of the branch pipe 27 away from the electric push rod 28 to reseal the discharge pipe 26, thereby preventing the raw material in evaporator 1 from leaking during the crystallization process.
[0031] During the crystallization process, motor 2 32 is started, which drives shaft 2 33 to rotate. The rotation of shaft 2 33 drives half-gear 34 to rotate, and half-gear 34 periodically contacts rack 36. When half-gear 34 contacts rack 36, it drives rack 36 to move. Rack 36 is limited by limiting plate 1 35, thus ensuring stable movement. Simultaneously, the sliding groove 1 311 expands the range of rack 36's movement. As rack 36 moves, it drives moving rod 38, which is then controlled by limiting plate 2 311. 37 is limited to ensure the stability of the movement of the moving rod 38. When the moving rod 38 moves, it drives the vibrating plate 39 to move and the spring 310 to contract. When the half gear 34 is not in contact with the rack 36, the spring 310 is reset and stretched under its own elasticity, which in turn drives the vibrating plate 39 and the moving rod 38 to move. The vibrating plate 39 moves and resets to impact the transmission plate 313, causing the transmission plate 313 to vibrate. The vibration is then transmitted to the discharge pipe 26 and the branch pipe 27, thereby preventing excessive accumulation of crystals during the feeding process and thus blocking the branch pipe 27.
