Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature vacuum distillation, in particular to a low-temperature vacuum distillation device convenient for material separation. Background Art

[0002] Vacuum distillation is a kind of distillation method. Vacuum distillation is carried out under reduced pressure, generally used for separating substances that are prone to decomposition when heated to the boiling point under normal pressure, or combined with other distillation methods to reduce the distillation temperature and improve the separation efficiency. This kind of distillation method needs to be completed with the help of a low-temperature vacuum distillation device.

[0003] The patent number CN219662901U discloses a low-temperature vacuum distillation device, including a bottom plate, a distillation box and a separation box installed at the upper end of the bottom plate. An inlet bin and a vacuum pump are arranged at the upper end of the distillation box. A valve is arranged on the inlet bin, and an air extraction pipe extending into the distillation box is arranged on the vacuum pump. A low-temperature separation component is arranged in the separation box. In this low-temperature vacuum distillation device, materials are poured into the distillation box through the inlet bin, and the internal environment is evacuated by the vacuum pump. After distillation and vaporization, it is pumped into the separation box by the first suction machine. Then, the temperature of the condenser is adjusted through the temperature control panel to condense the vaporized substances, so that some gaseous substances with higher boiling points are liquefied and enter the first storage area through the mixed discharge pipe. The remaining gaseous substances with low boiling points can be completely cooled and liquefied through the water-cooling component and then enter the second storage area, thereby automatically separating the substances and making the device more convenient and applicable.

[0004] However, the above-mentioned low-temperature vacuum distillation device still has the following deficiencies:

[0005] Although the above device can drive the stirring blades on the outer side to rotate by the motor to stir the substances in the distillation box, the stirring blades can only stir in a fixed horizontal direction, so that the stirring range is still limited, resulting in insufficient stirring and uneven heating of the materials, thereby reducing the material separation efficiency. In view of this, we propose a low-temperature vacuum distillation device convenient for material separation. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a low-temperature vacuum distillation device convenient for material separation, so as to solve the technical problem that the stirring blades of the above device can only stir in a fixed horizontal direction, resulting in a limited stirring range, insufficient stirring, uneven heating of the materials, and thus reducing the material separation efficiency.

[0007] To achieve the object of the present utility model, the technical solution adopted by the present utility model is as follows: Design a low-temperature vacuum distillation device for facilitating material separation, including a low-temperature distillation tank. An inlet assembly is provided on the left side of the low-temperature distillation tank. A stirring mechanism is provided in the middle of the low-temperature distillation tank. A vacuum pump assembly is provided on the top of the low-temperature distillation tank. A transfer pipe is connected to the right side of the low-temperature distillation tank, and the right end of the transfer pipe is connected to a condensation separation device;

[0008] The stirring mechanism includes a motor. A fixed frame is sleeved outside the motor. The movable end of the motor is connected to a rotating shaft. A spiral blade is wound on the surface of the rotating shaft. A number of stirring rods are staggered on both sides of the rotating shaft. Adjacent stirring rods on the same side are connected by a connecting rod. One end of the stirring rod away from the rotating shaft is connected to a scraping plate.

[0009] Preferably, the rotating shaft is connected to the scraping plate through the stirring rod, and the scraping plate matches the inner wall structure of the low-temperature distillation tank.

[0010] Preferably, the low-temperature distillation tank includes a tank body. A docking frame is provided on the right side of the tank body. A cover plate is snap-fitted inside the top of the tank body. The tank body and the cover plate are connected by bolts.

[0011] Preferably, the inlet assembly includes a limit groove frame. A clamping groove is opened on the inner wall of the limit groove frame. A filter screen plate is snap-fitted inside the limit groove frame. A group of clamping blocks are symmetrically arranged on the side surface of the filter screen plate. A pull rod is provided on the top of the clamping block. An inlet pipe is provided at the bottom of the limit groove frame. A valve is provided on the surface of the inlet pipe.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The present utility model effectively drives the rotation of the rotating shaft through the motor, thereby driving the rotation of the spiral blade and the stirring rod. The rotation of the spiral blade can stir the material vertically, and the rotation of the stirring rod can stir the material horizontally, improving the stirring effect, facilitating the uniform heating of the material, and thus enhancing the material separation efficiency. When the stirring rod rotates, it can effectively drive the movement of the scraping plate, so that the scraping plate effectively scrapes and cleans the inner wall of the tank, reducing the adhesion of the material on the inner wall of the tank. At the same time, the movement of the scraping plate after the distillation is completed improves the cleaning efficiency of the inner wall of the tank.

[0016] 2. In the present utility model, the material to be distilled is poured into the internal part of the limit groove frame. Meanwhile, the valve is opened. After being filtered by the filter screen plate, the material flows into the internal part of the tank body through the feed pipe. Since the filter screen plate is clamped in the internal part of the slot through the clamping block, when it is necessary to clean the filter residue on the surface of the filter screen plate, the filter screen plate can be pulled out integrally by pulling the pull rod upwards, which is relatively convenient.

[0025] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0026] A low-temperature vacuum distillation device for facilitating material separation, referring to Figures 1 to 4 , includes a low-temperature distillation tank 1. A feeding assembly 2 is arranged on the left side of the low-temperature distillation tank 1. A stirring mechanism 3 is arranged in the middle of the low-temperature distillation tank 1. A vacuum pump assembly 4 is arranged on the top of the low-temperature distillation tank 1. The right side of the low-temperature distillation tank 1 is connected with a transfer pipe 5, and the right end of the transfer pipe 5 is connected with a condensation separation device 6;

[0027] The stirring mechanism 3 includes a motor 301. A fixed frame 302 is sleeved outside the motor 301. A rotating shaft 303 is connected to the movable end of the motor 301. A spiral blade 304 is wound around the surface of the rotating shaft 303. A number of stirring rods 305 are staggered on both sides of the rotating shaft 303. Adjacent stirring rods 305 on the same side are connected by a connecting rod 306. One end of the stirring rod 305 away from the rotating shaft 303 is connected to a scraping plate 307. Among them, the rotating shaft 303 is connected to the scraping plate 307 through the stirring rod 305. The scraping plate 307 matches the inner wall structure of the low-temperature distillation tank 1. In the present utility model, the motor 301 effectively drives the rotation of the rotating shaft 303, thereby driving the rotation of the spiral blade 304 and the stirring rod 305. The rotation of the spiral blade 304 can stir the material vertically, and the rotation of the stirring rod 305 can stir the material horizontally, improving the stirring effect, facilitating the uniform heating of the material, and thus enhancing the material separation efficiency. When the stirring rod 305 rotates, it can effectively drive the movement of the scraping plate 307, so that the scraping plate 307 effectively scrapes and cleans the inner wall of the tank body 101, reducing the adhesion of the material on the inner wall of the tank body 101. At the same time, the movement of the scraping plate 307 after the distillation is completed improves the cleaning efficiency of the inner wall of the tank body 101.

[0028] It should be noted that the low-temperature distillation tank 1 includes a tank body 101. A docking frame 102 is provided on the right side of the tank body 101. A cover plate 103 is snap-fitted inside the top of the tank body 101. The tank body 101 and the cover plate 103 are connected by bolts 104.

[0029] It should be explained that the feeding assembly 2 includes a limit groove frame 201. A clamping groove 202 is formed on the inner wall of the limit groove frame 201. A filter screen plate 203 is snap-fitted inside the limit groove frame 201. A group of clamping blocks 204 are symmetrically arranged on the side surface of the filter screen plate 203. Further, the filter screen plate 203 and the clamping blocks 204 are integrally formed. The clamping blocks 204 are matched and snap-fitted inside the clamping grooves 202. A pull rod 205 is provided on the top of the clamping blocks 204. A feeding pipe 206 is provided at the bottom of the limit groove frame 201. Further, the limit groove frame 201 is connected to the low-temperature distillation tank 1 through the feeding pipe 206. The feeding pipe 206 and the low-temperature distillation tank 1 are fixedly connected. A valve 207 is provided on the surface of the feeding pipe 206. In the present utility model, the material to be distilled is poured into the limit groove frame 201. At the same time, the valve 207 is opened. The material flows into the tank body 101 through the feeding pipe 206 after being filtered by the filter screen plate 203. Since the filter screen plate 203 is snap-fitted inside the clamping grooves 202 through the clamping blocks 204, when it is necessary to clean the filter residue on the surface of the filter screen plate 203, the filter screen plate 203 can be pulled out upward by pulling the pull rod 205, which is relatively convenient.

[0030] Working principle: Pour the material to be distilled into the inside of the limit groove frame 201. At the same time, open the valve 207. After the material is filtered by the filter screen plate 203, it flows into the inside of the tank body 101 through the feed pipe 206. After all the material to be distilled is poured into the inside of the tank body 101, close the valve 207. Then, operate the vacuum pump assembly 4 to evacuate the air in the tank body 101 to make it vacuum. At the same time, the tank body 101 starts to heat the internal material. Drive the rotating shaft 303 to rotate through the motor 301, thereby driving the spiral blade 304 and the stirring rod 305 to rotate. The rotation of the spiral blade 304 can stir the material vertically, and the rotation of the stirring rod 305 can stir the material horizontally, improving the stirring effect, facilitating the uniform heating of the material, thereby enhancing the material separation efficiency. When the stirring rod 305 rotates, it can drive the scraper 307 to move, so that the scraper 307 scrapes and cleans the inner wall of the tank body 101, reducing the adhesion of the material on the inner wall of the tank body 101. Then, the suction machine inside the docking frame 102 sucks the vaporized substances converted by the heated material into the condensation and separation device 6, and the condensation and separation device 6 performs low-temperature condensation and separation on the vaporized substances.

Those of ordinary skill in the art can easily understand the spirit of the present utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
