Description

Technical Field

[0001] This application relates to the technical field of molecular evaporators, and particularly to a visual molecular evaporator. Background Art

[0002] A molecular evaporator is an important device for achieving material distillation and separation based on the principle of liquid evaporation. It is mainly used to separate various substances in a mixture through temperature differences to achieve the purpose of material purification. By utilizing the differences in the volatility of different molecules, it operates in a low-temperature and high-vacuum environment, effectively avoiding the decomposition or polymerization of heat-sensitive substances and maintaining the purity and quality of the product. It has a wide range of applications in many fields, such as the chemical industry, biopharmaceuticals, food industry, petroleum industry, etc.

[0003] The structure of the molecular evaporator is as shown in the attached instructions Figure 1 As shown, generally for facilitating real-time observation of the evaporation state of the internal material, the outer kettle body usually adopts a transparent material, such as glass, to observe the heating state and evaporation state of the internal material, and to avoid problems such as the material being overheated and scorched. Under the heating effect, the molecules in the liquid start to evaporate, generating gaseous molecules that rise upward and flow out from the top of the outer kettle body. The gas located inside the outer kettle body will form droplets that adhere to the inner wall of the outer kettle body under the action of the inner and outer condenser tubes, and these droplets usually move downward along the inner wall of the outer kettle body and fall off. For liquids with a certain viscosity, they will adhere to the inner wall of the outer kettle body. When the evaporation time is too long, more droplets will accumulate on the inner wall of the outer kettle body, resulting in a decrease in the visualization effect of the outer kettle body, making it impossible to directly observe the heating and evaporation states of the internal material and affecting the evaporation effect. Summary of the Invention

[0004] Aiming at the above problems, this application aims to provide a visual molecular evaporator that continuously cleans the droplets adhering to the inner wall of the outer kettle body, solves the influence of droplet aggregation during long-term evaporation operations, and at the same time, through the active cleaning of this cleaning mechanism, can effectively improve the cleanliness of the inner wall of the outer kettle body, thereby ensuring the visualization effect during the evaporation process and ensuring the evaporation effect of the material.

[0005] To achieve the above object, the technical solution adopted in this application is as follows: A visual molecular evaporator includes an outer kettle body and an inner cylinder rotatably arranged inside it. An internal cooling tube and an external cooling tube are sequentially arranged inside and outside the inner cylinder. It is characterized in that: The inner wall of the outer kettle body is provided with an active detachment structure for detaching the adhered liquid, and a cleaning mechanism connected to its interior is also arranged in the inner cavity of the outer kettle body.

[0006] Preferably, the active detachment mechanism is to set the inner wall of the outer kettle body as an upward inverted conical structure.

[0007] Preferably, the cleaning mechanism includes inclined scraping plates that are vertically spaced and horizontally staggered on the outer wall of the inner cylinder and abut against the inner wall of the outer kettle.

[0008] Preferably, a flexible scraping plate is provided at the front end of each inclined scraping plate.

[0009] The beneficial effect of this application is that through the active detachment structure provided on the inner wall of the outer kettle of this molecular evaporator, the droplets adhering to the inner wall of the outer kettle can be actively detached and dropped, solving the problem that the droplets adhering to the inner wall accumulate more during evaporation, affecting the visualization effect of the outer kettle, so as to observe the internal evaporation state in real time.

[0010] And through the cleaning mechanism, the droplets adhering to the inner wall of the outer kettle can be actively and continuously cleaned during the evaporation process, solving the influence of droplet accumulation during long-term evaporation operation. At the same time, through the active cleaning of this cleaning mechanism, the cleanliness of the inner wall of the outer kettle can be effectively improved, thus ensuring the visualization effect during the evaporation process and the evaporation effect of the material.

[0019] In order to enable ordinary technicians in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below with reference to the drawings and embodiments.

[0020] Refer to the attached Figures 1 - 6A visualized molecular evaporator as shown includes an outer kettle body 1 and an inner cylinder 2 rotatably arranged inside it. An internal cooling pipe 31 and an external cooling pipe 32 are sequentially arranged inside and outside the inner cylinder 2. Among them, the outer kettle body 1 is preferably made of visualized glass material. Since there is a heating process during the operation of the molecular evaporator, through the glass material, the heating state of the material inside the molecular evaporator can be directly observed, avoiding problems such as scorching caused by too high heating temperature.

[0021] During the operation of this molecular evaporator, the gas evaporated in its inner cavity will adhere to the inner wall of the outer kettle body 1 and become droplets after condensation, and usually drop along the inner wall of the outer kettle body 1. For liquids with a certain viscosity, they will adhere to the inner wall of the outer kettle body 1. When the evaporation time is too long, more droplets adhere to the inner wall of the outer kettle body 1, resulting in a decline in the visualization effect of the outer kettle body 1, and the heating and evaporation states of the internal material cannot be directly observed, affecting the evaporation effect. Therefore, to solve this problem, as Figure 4 shown, the inner wall of the outer kettle body 1 is provided with an active detachment structure for detaching the adhered liquid. Through this active detachment structure, the droplets adhering to the inner wall of the outer kettle body 1 can be actively detached and dropped, solving the problem that the droplets adhering to the inner wall accumulate more with the progress of evaporation and affecting the visualization effect of the outer kettle body 1, so as to observe the internal evaporation state in real time and ensure the evaporation effect of the material.

[0022] To further solve the removal effect of the droplets adhering to the inner wall of the outer kettle body 1, as Figure 6 shown, a cleaning mechanism connected to its interior is also arranged in the inner cavity of the outer kettle body 1. This cleaning mechanism can actively and continuously clean the droplets adhering to the inner wall of the outer kettle body 1 during the evaporation process, solving the influence of droplet accumulation during long-term evaporation operations. At the same time, through the active cleaning of this cleaning mechanism, the cleanliness of the inner wall of the outer kettle body 1 can be effectively improved, thus ensuring the visibility effect during the evaporation process and the evaporation effect of the material.

[0023] Specifically, as Figures 3 - 5 shown, the active detachment mechanism is to set the inner wall of the outer kettle body 1 as an upward inverted conical structure. Under this structure, the inner wall of the outer kettle body 1 is a slanting structure with respect to the vertical plane. As Figure 5 shown, the droplets adhering to the inner wall of the outer kettle body 1 during the evaporation process will drop vertically under the action of their gravity. Due to the deviation of the outer kettle body 1 from the vertical plane, the dropped droplets will be detached from the inner wall surface of the outer kettle body 1 (the vertical inner wall of the outer kettle body 1 will cause the adhering droplets to always contact the inner wall surface during the falling process), thus avoiding the accumulation of droplets during the evaporation process and the influence on visualization due to adhering to the inner wall of the outer kettle body 1.

[0024] When the viscosity of the evaporated droplets is relatively high, the difficulty of detaching and falling along the inner wall surface of the outer kettle body 1 increases. Specifically, as Figure 6 shown, the cleaning mechanism includes inclined scraping plates 4 that are arranged at upper and lower intervals and left and right staggered on the outer wall of the inner cylinder body 2 and abut against the inner wall of the outer kettle body 1. Since the inner cylinder body 2 of this molecular evaporator has a rotating working state during operation, under the driving of the rotation of the inner cylinder body 2, each inclined scraping plate 4 is driven to scrape the droplets remaining and adhering to the inner wall surface of the outer kettle body 1 along the circumferential direction. And because each inclined scraping plate 4 is inclined, it has a downward scraping effect during the scraping process. Preferably, the downward adjacent inclined scraping plates 4 are connected in the horizontal plane. Therefore, during the scraping process, the upper inclined scraping plate 4 drives the scraped droplets to the lower inclined scraping plate 4, and they are connected in sequence from top to bottom to achieve the active scraping of the droplets adhering to the inner wall of the outer kettle body 1. And arranging the inclined scraping plates 4 at upper and lower intervals and left and right staggered avoids a large blockage of the inclined scraping plates 4, which affects the visualization effect of the outer kettle body 1.

[0025] Since the inner wall of the outer kettle body 1 of this application is set as a conical structure, and usually the bottom of the outer kettle body 1 is an arc structure for facilitating discharging, in order to enable the inclined scraping plates 4 to effectively scrape droplets according to the change of the inner wall surface structure of the outer kettle body 1, as Figure 6 shown, a flexible scraping plate 5 is provided at the front end of each inclined scraping plate 4. The flexible scraping plate 5 can preferably be a rubber scraping plate, which can be deformed to fit on the inner wall surface of the outer kettle body 1, so as to ensure an effective scraping and cleaning effect, further improve the visualization effect of the outer kettle body 1, and ensure the evaporation treatment effect of the material.

[0026] The principle of this application is: the inner wall of the outer kettle body 1 is set as an upward inverted conical structure. Under this structure, the droplets adhering to the inner wall of the outer kettle body 1 during the evaporation process will vertically fall under the action of their gravity. And because the outer kettle body 1 deviates from the vertical plane, the falling droplets will separate from the inner wall surface of the outer kettle body 1, thus avoiding the aggregation of droplets during the evaporation process and the influence on visualization caused by adhering to the inner wall of the outer kettle body 1.

[0027] Furthermore, inclined scraping plates 4 that are arranged at upper and lower intervals and left and right staggered on the outer wall of the inner cylinder body 2 and abut against the inner wall of the outer kettle body 1 are provided, and a flexible scraping plate 5 is provided at the front end of the inclined scraping plate 4. It can be deformed to fit on the inner wall surface of the outer kettle body 1, so as to ensure an effective scraping and cleaning effect, further improve the visualization effect of the outer kettle body 1, and ensure the evaporation treatment effect of the material.

[0028] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
