Description

Technical Field

[0001] This utility model relates to the field of hexane solvent purification technology, specifically to a multi-stage filtration hexane solvent purification device. Background Technology

[0002] Hexane, also known as n-hexane, is an important petroleum hydrocarbon. Due to its good solubility and low polarity, hexane plays a vital role in various fields, including chemistry, industry, pharmaceuticals, and daily life. Despite its broad application prospects, hexane solvent can be contaminated during use, with contaminants potentially originating from raw materials, the production process, or the storage environment. The presence of contaminants can affect hexane's solubility, volatility, and chemical stability, thus impacting its performance in various applications. Therefore, purification of hexane is essential.

[0003] Currently, the purification of hexane solvent mainly employs distillation. The hexane solvent containing impurities is placed in a distillation flask and heated to evaporate the hexane. The evaporated gas is then cooled by a condenser, and the pure hexane settles at the bottom of the container. However, if the hexane solvent contains a large amount of suspended solids, particulate matter, or other large molecular impurities, these impurities may adhere to the inside of the distillation equipment during the distillation process, affecting heat transfer and liquid flow, thereby reducing distillation efficiency. Therefore, we propose a multi-stage filtration hexane solvent purification system. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage filtration hexane solvent purification device to solve the problems mentioned in the background art.

[0030] This embodiment provides a technical solution:

[0031] Please see Figures 1-4As shown, the multi-stage filtration hexane solvent purification equipment includes two symmetrical bases 1, with a top seat 2 above the bases 1.

Side plates 33 are fixed to the front and rear sides of the top of the filter box 3, and connecting bolts 330 pass through the side plates 33. A top plate 32 is located between the two side plates 33, with a feeding port 320 installed at the top of the top plate 32. Threaded holes 321 are opened on the front and rear walls of the top plate 32, and the connecting bolts 330 are threaded into the threaded holes 321. Two fixing devices for inserting the filter box 3 are fixed at the bottom of the top plate 32. Plate 34, with multiple detachable mounting brackets 35 fixed between the two fixed plates 34, and a filter screen 36 for filtering hexane solvent fixed in the opening of the mounting bracket 35; a distillation tank 4 is fixed at the top rear side of the base 1 above, and the distillation tank 4 is connected to the discharge port 30; an exhaust port 40 is installed on one side of the top of the distillation tank 4, and multiple electric heating blocks 41 are installed at the bottom inside the distillation tank 4; a hollow cooling box 5 is installed on the front side of the distillation tank 4, and a condenser tube 53 is fixed inside the cooling box 5. The water inlet and water outlet of the condenser tube 53 both pass through the cooling box 5, and an exhaust pipe 52 connected to the exhaust port 40 is installed at the water inlet of the condenser tube 53.

[0032] In this embodiment, an inlet 50 and a drain 51 are respectively installed on the upper and lower sides of the outer wall of the cooling box 5, and both the inlet 50 and the drain 51 are connected to the cooling box 5. The arrangement of the inlet 50 and the drain 51 facilitates the entry and exit of cooling water into and out of the cooling box 5, thereby facilitating the condensation of high-temperature steam in the condenser tube 53 by the cooling water.

[0033] In this embodiment, multiple slots 340 are provided on each of the two opposing end faces of the two fixing plates 34, and insert strips 350 are fixed on both outer walls of the mounting bracket 35. The insert strips 350 are inserted into the corresponding slots 340. This design facilitates the assembly and disassembly of the mounting bracket 35 while ensuring the secure installation of the mounting bracket 35.

[0034] In this embodiment, the top plate 32 is perpendicular to the fixed plate 34, and the top plate 32 and the fixed plate 34 are fixedly connected by bolts. The outer wall of the fixed plate 34 is in contact with the inner wall of the filter box 3. This design ensures a tight connection between the fixed plate 34 and the inner cavity of the filter box 3, thereby ensuring the filtration effect.

[0035] In this embodiment, the feeding port 320 is funnel-shaped and is fixedly connected to the top plate 32 by bolts. The funnel-shaped design facilitates feeding, while the bolt fixing method ensures the reliable installation and stability of the feeding port 320.

[0036] In this embodiment, the condenser tube 53 has a spiral shape and is made of glass. The spiral design increases the flow path of the steam, thus facilitating the condensation of the steam, while the glass material has the advantage of good thermal conductivity, which is conducive to better condensation of the steam.

[0037] In this embodiment, the outer wall of the distillation tank 4 is provided with an observation window, which is transparent. This design facilitates observation of the conditions inside the distillation tank 4 and helps staff understand the work progress.

[0038] In this embodiment, a first support rod 10 is fixed at each of the four corners between the two bases 1, and multiple second support rods 20 are fixed between the base 1 and the top base 2. The first support rods 10 and the second support rods 20 provide stable support and fixation for the device, ensuring the overall stability and reliability of the device.

[0039] It is understood that a valve 31 is installed at the discharge port 30 in this embodiment. The valve 31 is designed to facilitate the opening and closing of the discharge port 30, thereby facilitating the control of the discharge. At the same time, it can prevent steam from flowing back into the filter box 3 during distillation.

[0040] In practical use, the user first adds hexane solvent through the feed port 320. The hexane solvent enters the filter box 3 and falls onto the filter screen 36. Under the action of gravity, the hexane solvent passes through multiple filter screens 36, and impurities in the hexane solvent are trapped on multiple filter screens 36. The filtered hexane solvent falls into the distillation tank 4 through the discharge port 30. At this time, the user closes the valve 31 and then turns on the power supply of the heating block 41. The heating block 41 starts to work and heats the hexane solvent. After the hexane solvent evaporates, it forms steam and enters the exhaust pipe 52 through the exhaust port 40. At this time, the steam enters the condenser 53 through the exhaust pipe 52. The cooling water source cools the condenser 53 at the same time. The steam in the condenser 53 is cooled and liquefied. Finally, the liquefied hexane solvent is discharged through the bottom opening of the condenser 53.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
