Abstract
Description
Technical Field
[0001] The utility model relates to the field of hexane filtration, and particularly relates to a hexane filtration device. Background Technique
[0002] n-Hexane is a hydrocarbon naturally present in petroleum and is also one of the main components of petroleum ether and naphtha. Its chemical formula is C6H14, belonging to straight-chain saturated aliphatic hydrocarbons. It is a colorless transparent liquid at room temperature with a slight petroleum odor. It is volatile, and its vapor is heavier than air. It forms an explosive mixture with air, and the explosion limit is 1.18% - 7.4% (volume fraction). n-Hexane is widely used as an edible oil extraction solvent, rubber solvent, artificial leather finishing agent, precision device cleaning agent, clothing stain remover, pharmaceutical tablet detergent, and preparation of mixed solvents, etc. n-Hexane has 4 isomers, 2-methylpentane (isohexane), 3-methylpentane, 2,3-dimethylbutane (diisopropyl alkane), 2,2-dimethylbutane (neohexane), all of which are colorless, volatile, flammable liquid alkanes with a faint special odor. In order to obtain hexane with higher purity, a filtration device is needed to filter hexane.
[0003] When the existing filtration device filters hexane, most of them use a filter screen for filtration. When the traditional filter screen faces larger particulate matter, it is prone to clogging, resulting in blocked fluid flow and affecting the overall filtration performance. Further improvement is needed. For this reason, a hexane filtration device is proposed. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a hexane filtration device, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A hexane filtration device includes a second cylinder body, the upper end of the second cylinder body is connected to a first cylinder body, the lower end of the second cylinder body is connected to a third cylinder body, several drain pipes are inserted and connected to the upper end of the first cylinder body, a liquid inlet pipe is inserted and connected to the lower end of the third cylinder body, a support component is arranged on the inner wall surface of the second cylinder body, a first filtration component is arranged inside the support component, a first sieve plate, a second filtration component, and a second sieve plate are sequentially arranged on the inner wall surface of the third cylinder body from top to bottom, and a guiding component is connected to the upper end of the liquid inlet pipe.
[0007] Preferably, the support component includes a hollow cylinder, the hollow cylinder is detachably connected to the inner wall surface of the second cylinder body, the lower end of the hollow cylinder is detachably connected to a third sieve plate, a through groove is opened at the upper end of the hollow cylinder, a fourth sieve plate is arranged at the upper end of the through groove, and the fourth sieve plate is detachably installed at the upper end of the hollow cylinder.
[0008] Preferably, the first filtering component includes a glass ball layer disposed at the upper end of the third sieve plate, an adsorbent layer is arranged above the glass ball layer, and a filtering particle layer is arranged above the adsorbent layer.
[0009] Preferably, the first filtering component has the same structure as the second filtering component.
[0010] Preferably, the guiding component includes a connecting pipe installed at the upper end of the liquid inlet pipe. The upper end of the connecting pipe is connected to a hollow plate, and a plurality of spray heads are fixedly inserted through the upper end of the hollow plate. The spray heads are located below the second sieve plate.
[0011] Preferably, an observation window is installed on the outer surface of the third cylinder.
[0012] Compared with the prior art, the present utility model has the following beneficial effects:
[0013] 1. By setting the supporting component, the first filtering component, the second filtering component, the first sieve plate and the second sieve plate to cooperate together, the filtering effect can be improved. Through the first filtering component and the second filtering component, suspended solids, impurities and other pollutants in the liquid can be effectively intercepted and removed, thereby improving the purity of the liquid. The particles inside the first filtering component and the second filtering component can float up and down, avoiding blockage, ensuring the overall filtering performance. At the same time, the supporting component and the first sieve plate can be disassembled to facilitate the filtering of the first filtering component and the second filtering component;
[0014] 2. By setting the guiding component, the flow rate of the liquid entering the second sieve plate can be balanced. During use, the liquid enters the hollow plate through the connecting pipe and then sprays out from the spray heads, making the pressure of the liquid at the bottom of the second sieve plate the same. Uniform guiding can effectively reduce the flow resistance in the middle, promote the smooth flow of the liquid. By guiding the liquid to multiple positions, the filtering failure caused by excessive load on a certain part of the filtering component can be avoided, ensuring the stability of the filtering process.

[0023] As Figures 1 - 4 shown, a hexane filtering device includes a second cylinder 3. The upper end of the second cylinder 3 is detachably connected to the first cylinder 2 by bolts. An ear seat 4 is arranged on the outer surface of the second cylinder 3. The lower end of the second cylinder 3 is detachably connected to the third cylinder 7. A plurality of drain pipes 1 are inserted and connected to the upper end of the first cylinder 2. Specifically, three drain pipes 1 are provided. The lower end of the third cylinder 7 is inserted and connected to the liquid inlet pipe 10. A supporting component 11 is arranged on the inner wall surface of the second cylinder 3. A first filtering component 12 is arranged inside the supporting component 11. A first sieve plate 8, a second filtering component 13 and a second sieve plate 9 are sequentially arranged on the inner wall surface of the third cylinder 7 from top to bottom. The first sieve plate 8 and the second sieve plate 9 are detachably connected to the inner wall surface of the third cylinder 7 by bolts.
[0024] During use, pour the liquid into the third cylinder body 7 through the liquid inlet pipe 10. The second filtering component 13 conducts preliminary filtration on the hexane liquid, and then it flows into the second cylinder body 3, where it is subjected to secondary filtration by the first filtering component 12, and then is discharged through the liquid discharge pipe 1. Since the internal particles of the second filtering component 13 and the first filtering component 12 can float up and down, the probability of blockage is reduced, ensuring the overall filtering performance. When it is necessary to replace the first filtering component 12 and the second filtering component 13, disassemble the first cylinder body 2, the support component 11 and the first sieve plate 8, take out the failed first filtering component 12 and the second filtering component 13, and pour in new first filtering component 12 and second filtering component 13.
[0025] The support component 11 can support the first filtering component 12. The support component 11 includes a hollow cylinder 111. The hollow cylinder 111 is detachably connected to the inner wall surface of the second cylinder body 3 by bolts. The lower end of the hollow cylinder 111 is detachably connected with a third sieve plate 112. The upper end of the hollow cylinder 111 is provided with a through groove 113. The upper end of the through groove 113 is provided with a fourth sieve plate 114. The fourth sieve plate 114 is detachably installed at the upper end of the hollow cylinder 111. The diameters of the third sieve plate 112 and the fourth sieve plate 114 are smaller than the diameter of the filtering particles in the first filtering component 12.
[0026] The first filtering component 12 includes a glass ball layer 121. The glass ball layer 121 is arranged above the third sieve plate 112. An adsorbent layer 122 is arranged above the glass ball layer 121. The glass ball layer 121 is used to support the adsorbent layer 122. A filtering particle layer 123 is arranged above the adsorbent layer 122. The adsorbent layer 122 and the filtering particle layer 123 are used to adsorb and filter impurities. The first filtering component 12 and the second filtering component 13 have the same structure. The diameters of the sieve holes of the first sieve plate 8 and the second sieve plate 9 are smaller than the diameter of the filtering particles in the second filtering component 13.
[0027] In addition, when the hexane liquid with a relatively high pressure enters the third cylinder body 7 through the liquid inlet pipe 10, the liquid pressure in the middle of the third cylinder body 7 is relatively high, which may cause more liquid to be filtered in the middle of the second filtering component 13, resulting in filtration failure due to overloading. To ensure the stability of the filtering process, a guiding component 6 is connected to the upper end of the liquid inlet pipe 10. Specifically, the guiding component 6 includes a connecting pipe 61. The connecting pipe 61 is installed at the upper end of the liquid inlet pipe 10. The upper end of the connecting pipe 61 is connected with a hollow plate 62. A plurality of spray heads 63 are fixedly inserted and connected to the upper end of the hollow plate 62. The spray heads 63 are located below the second sieve plate 9. During use, the liquid enters the hollow plate 62 through the connecting pipe 61 and then sprays out from the spray heads 63, making the liquid pressure at the bottom of the second sieve plate 9 the same. Uniform guiding can effectively reduce the flow resistance in the middle and promote the smooth flow of the liquid. By guiding the liquid to multiple positions inside the second filtering component 13.
[0028] In order to observe the interior of the third cylinder body 7, an observation window 5 is installed on the outer surface of the third cylinder body 7.
