Description

Technical Field

[0001] The present application relates to the technical field of molecular evaporators, and particularly to a molecular evaporator for preventing liquid residue. Background Art

[0002] Molecular distillation is a special liquid-liquid separation technology. Different from the traditional distillation based on the separation principle of the boiling point difference of substances, it realizes separation based on the difference in the average free path of molecular motion of each substance in the mixture. According to the average free path of molecular motion, in an ideal state, the liquid mixture is heated by flowing along the heating plate. The light and heavy molecules will escape from the liquid surface and enter the gas phase. Since the free paths of the light and heavy molecules are different, the molecules of different substances move different distances after escaping from the liquid surface. By setting a condensation plate, the light molecules reach the condensation plate and are condensed and discharged, while the heavy molecules cannot reach the condensation plate and are discharged along with the liquid mixture, achieving the purpose of separating substances. Based on this principle, various molecular evaporators such as centrifugal and wiping film types have been designed.

[0003] The main structure of the current molecular evaporator is as Figure 1-2 shown, mainly including a cylinder for liquid evaporation and a liquid outlet provided at the bottom of the cylinder. After the liquid to be distilled is distilled in the cylinder, the distilled liquid can be discharged by opening the liquid outlet at the lower part. The current cylinder is a conventional cylindrical structure, and its upper and lower (cover) plate bodies are both flat structures. If the cylinder is skewed during assembly, the liquid will form residues on the bottom plate ( Figure 2 as shown in a in), and the liquid cannot be fully discharged, affecting the distillation effect of different liquids next time; when the surface flatness of the bottom plate is poor during processing, there will still be liquid residues on its surface, affecting the later distillation operation effect; and if the fluidity of the liquid is poor, the amount of residues on the bottom plate is more. Summary of the Invention

[0004] In view of the above problems, the present application aims to provide a molecular evaporator for preventing liquid residue, which can completely discharge the liquid distilled in the cylinder through the liquid outlet, and mechanically scrape the residual liquid, thereby improving the cleanliness of the inner cavity of the cylinder and avoiding the influence of residues on the subsequent distillation of liquids.

[0005] To achieve the above object, the technical solution adopted in the present application is as follows: A molecular evaporator for preventing liquid residue, the molecular evaporator includes a cylinder, and a liquid outlet is provided at the bottom end of the cylinder. It is characterized in that: the connection between the bottom end of the cylinder and the liquid outlet is set as an easy-flow-out structure, and a scraping component that can be in contact with the inner wall surface of the easy-flow-out structure is detachably inserted in the liquid outlet.

[0006] Preferably, the easy-flow-out structure is that the bottom of the cylinder is set as a semi-circular body, and the liquid outlet is provided at the center of the bottom of the semi-circular body.

[0007] Preferably, the scraping component includes an operating rod that can penetrate into the liquid outlet, and flexible scraping belts are circumferentially spaced at the top end of the operating rod.

[0008] Preferably, the top end of each flexible scraping belt is provided with a hook body structure.

[0009] The beneficial effect of this application is that the connection between the bottom end of the cylinder and the liquid outlet is set as an easy-flow structure. Through this easy-flow structure, the residue of the liquid on the bottom plate of the cylinder can be solved, so that the liquid after distillation treatment in the cylinder can be completely discharged through the liquid outlet, thus avoiding the influence of the residue on the subsequent liquid distillation.

[0010] And through this scraping component, a mechanical scraping operation is performed on the partially residual liquid due to poor fluidity, so as to realize the complete discharge of the liquid in the cylinder and improve the cleanliness of the inner cavity of the cylinder.

[0023] In order to enable those of ordinary skill in the art to better understand the technical solution of the present application, the technical solution of the present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Refer to the attached Figures 1 to 11 As shown in a molecular evaporator for preventing liquid residue, the molecular evaporator includes a cylinder body 1, and a liquid outlet 2 is provided at the bottom end of the cylinder body 1. After the distillation treatment of the liquid is completed, it is discharged through the liquid outlet 2. In order to solve the problem that liquid remains in various situations on the inner bottom plate of the current cylinder body 1, such as Figures 3-4 As shown, the present application sets the connection between the bottom end of the cylinder body 1 and the liquid outlet 2 as an easy - outflow structure. Through this easy - outflow structure, the residue of the liquid on the bottom plate of the cylinder body 1 can be solved, so that the liquid after distillation treatment in the cylinder body 1 can be completely discharged through the liquid outlet 2, thereby avoiding the influence of the residue on the subsequent liquid distillation.

[0025] When the fluidity of the liquid body is poor and there is still some residue, a scraping component that can be detachably inserted into the liquid outlet 2 and is in contact with the inner wall surface of the easy - outflow structure is provided. Through this scraping component, a mechanical scraping operation is performed on the liquid that remains partially due to poor fluidity, so as to completely discharge the liquid in the cylinder body 1 and improve the cleanliness of the inner cavity of the cylinder body 1.

[0026] Specifically, as Figure 4 shown, the easy - outflow structure is to set the bottom of the cylinder body 1 as a semi - circular arc body 11, and the liquid outlet 2 is arranged at the center of the bottom of the semi - circular arc body 11. Among them, the liquid flows down along the inner wall surface of the semi - circular arc body 11 under the action of gravity, and the semi - circular arc body 11 itself does not have a flat structure, and there is no flat - structured connection corner between it and the cylinder body 1. Furthermore, through the semi - circular arc body 11, the liquid can flow out completely, thus ensuring the cleanliness of the inner cavity of the cylinder body 1, especially the bottom.

[0027] In order to solve the problem that the liquid with poor fluidity remains on the inner wall surface of the semi - circular arc body 11, as Figures 5-7 shown, the scraping component includes an operating rod 3 that can be inserted into the liquid outlet 2, and flexible scraping belts 31 are circumferentially spaced at the top end of the operating rod 3. Among them, the flexible scraping belts 31 can preferably be plastic - steel packing belts, which can be bent and have a certain strength. Therefore, when in use, a plurality of flexible scraping belts 31 are first tightened ( Figure 8As shown in the figure), then pass the flexible scraping belt 31 through the liquid outlet 2 into the inside of the cylinder body 1 through the operating rod 3. Then continue to drive the operating rod 3 upward. Each flexible scraping belt 31 bends according to its gravity and, under the continuous push of the operating rod 3, moves upward along the inner surface of the semi-cylindrical body 11 ( Figure 9 as shown by the arrow in the figure). Set the length of the flexible scraping belt 31 according to the arc length of the semi-cylindrical body 11. When its top reaches the connection between the top of the semi-cylindrical body 11 and the cylinder body 1, pull the operating rod 3 downward ( Figure 10 as shown in the figure), and drive the flexible scraping belt 31 to scrape the liquid remaining on the inner wall of the semi-cylindrical body 11.

[0028] To achieve an effective scraping effect, as Figure 11 shown in the figure, the top of each said flexible scraping belt 31 is set as a hook structure. This hook structure can preferably be a thin metal hook 4 fixed at the top of the flexible scraping belt 31. Since the inner groove faces downward, during the process of driving the hook upward through the flexible scraping belt 31, the contact between the hook and the remaining liquid will not achieve a scraping effect. However, during the process of pulling the flexible scraping belt 31 downward, the thin metal hook can effectively achieve a mechanical scraping of the liquid remaining on the inner wall of the semi-cylindrical body 11, further improving the cleanliness of the inner cavity of the cylinder body 1, especially the semi-circular arc at the bottom 11.

[0029] The principle of this application is: Set the bottom of the cylinder body 1 as a semi-cylindrical body 11. When the liquid is discharged after distillation is completed, the liquid flows downward along the inner wall surface of the semi-cylindrical body 11 under the action of gravity, thereby ensuring the cleanliness of the inner cavity of the cylinder body 1, especially the bottom.

[0030] When liquid with poor fluidity remains on the inner wall surface of the semi-cylindrical body 11, first tighten the multiple flexible scraping belts 31, then pass the flexible scraping belts 31 through the liquid outlet 2 into the inside of the cylinder body 1 through the operating rod 3. Then continue to drive the operating rod 3 upward. Each flexible scraping belt 31 bends according to its gravity and, under the continuous push of the operating rod 3, moves upward along the inner surface of the semi-cylindrical body 11. When its top reaches the connection between the top of the semi-cylindrical body 11 and the cylinder body 1, pull the operating rod 3 downward, and drive the thin metal hook provided at the top of the flexible scraping belt 31 to completely scrape the liquid remaining on the inner wall of the semi-cylindrical body 11, improving the cleanliness of the inner cavity of the cylinder body 1, especially the semi-circular arc at the bottom 11.

[0031] 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.
