Description

Technical Field

[0001] This utility model relates to the field of ethanol production, and in particular to a continuous filtration device suitable for ethanol production. Background Technology

[0002] During ethanol production, various trace amounts of reducing organic impurities or metal ions, such as propyl acetate (C5HO2), acetaldehyde (CH3CHO), and Fe3+, are easily generated in the produced ethanol due to the influence of many factors such as raw gas, catalyst, reaction temperature, reaction pressure, and space velocity. These impurities require filtration. However, some of the associated substances are soluble in ethanol and need to be reacted with other chemical substances to form precipitates for removal. Most existing ethanol filtration devices can only filter existing solid impurities in ethanol and cannot react the impurities in ethanol before filtration, making the existing ethanol filtration devices less practical.

[0003] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a continuous filtration device suitable for ethanol production, thereby addressing the aforementioned technical deficiencies.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A continuous filtration device suitable for ethanol production includes a reaction tank, a jacket fitted around the outside of the reaction tank, a cover plate bolted to the top of the reaction tank, a peristaltic pump bolted to the top of the cover plate, a stepper motor bolted to the top of the cover plate, and a feed pipe fixedly connected to the top of the cover plate.

[0007] Preferably, the jacket is provided with a snake tube inside, a solenoid valve is fixedly installed below the reaction tank, an infusion pump is provided below the solenoid valve, the inlet of the infusion pump is fixedly connected to one end of the solenoid valve through a pipe and is internally connected, and a connecting pipe is fixedly connected to the outlet of the infusion pump.

[0008] Preferably, the other end of the first connecting pipe is provided with a fixedly connected three-way valve, and both ends of the three-way valve are provided with fixedly connected second connecting pipes. A shell is placed on one side of the reaction tank, and mounting grooves are opened on both sides of the shell. The other end of the second connecting pipe extends into the mounting groove and communicates with the inside of the mounting groove.

[0009] Preferably, the inside of the cover plate is also fixedly provided with a through feed pipe, and the inside of the peristaltic pump is provided with a replaceable hose, one end of which extends into the feed pipe and communicates with the inside of the feed pipe.

[0010] Preferably, the stepper motor drive shaft passes through the cover plate and is fixedly provided with a stirring shaft, and the lower end of the stirring shaft is fixedly installed with a stirrer by bolts.

[0011] Preferably, a second solenoid valve is fixedly connected to one side of the feeding pipe, the feeding pipe is connected to the lower part of the cover plate, a filter box is placed inside the mounting groove, a filter chamber is opened inside the filter box, and an array of filter frames are also provided on the outside of the filter box, all of which are slidably connected to the filter box.

[0012] Preferably, each of the filter frames has a filter screen fixedly installed at its inner bottom, and each of the filter boxes has a fixedly connected collection pipe on one side.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention involves adding the ethanol to be processed into the reaction tank through the feed pipe. At this time, the reaction temperature in the reaction tank is controlled by adding high-temperature steam or cooling water into the coil inside the jacket. Then, the peristaltic pump is started to meter and add other chemical solvents required for the reaction into the reaction tank. Subsequently, the stepper motor is started to drive the stirrer to stir the reactants and accelerate the reaction.

[0015] After the reaction is complete, the infusion pump is started to draw out the ethanol liquid and reaction precipitate from the reaction tank, and then transported to the three-way valve through the first connecting pipe. At this time, the ethanol liquid flows into the corresponding filter chamber through the second connecting pipe on one side of the three-way valve for filtration. The filtered ethanol liquid flows out through the collection pipe. When one of the filter frames is blocked, the three-way valve is started to change the flow direction of the ethanol liquid, so that the ethanol liquid flows into the other filter chamber for filtration. At this time, the filtration operation of ethanol liquid can be continuously carried out, thereby greatly improving the filtration efficiency of ethanol liquid. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 5 As shown, this utility model is a continuous filtration device suitable for ethanol production, including a reaction tank 1. A jacket 11 is fitted on the outside of the reaction tank 1, and a serpentine tube is provided inside the jacket 11. A solenoid valve 12 is fixedly installed below the reaction tank 1, and a delivery pump 13 is provided below the solenoid valve 12. The delivery pump 13 is placed on the ground, and the inlet of the delivery pump 13 is fixedly connected to one end of the solenoid valve 12 through a pipe and is internally connected. A connecting pipe 14 is fixedly connected to the outlet of the delivery pump 13.

[0025] The other end of the connecting pipe 14 is provided with a fixed three-way valve 15. Both ends of the three-way valve 15 are provided with fixed connecting pipes 16. A shell 17 is placed on one side of the reaction tank 1. Both sides of the shell 17 are provided with mounting grooves 18. The other end of the connecting pipe 16 extends into the mounting groove 18 and communicates with the inside of the mounting groove 18.

[0026] A cover plate 19 is bolted to the top of the reaction vessel 1. A peristaltic pump 20 is bolted to the top of the cover plate 19. A through feed pipe 22 is also fixed inside the cover plate 19. A replaceable hose 21 is provided inside the peristaltic pump 20. One end of the hose 21 extends into the feed pipe 22 and communicates with the inside of the feed pipe 22. The hose 21 is used to transport the reaction liquid.

[0027] A stepper motor 23 is also fixed above the cover plate 19 by bolts. The drive shaft of the stepper motor 23 passes through the cover plate 19 and is fixed to a stirring shaft 24. A stirrer 25 is fixed to the lower end of the stirring shaft 24 by bolts. When the stepper motor 23 starts, it drives the stirring shaft 24 to rotate, and the stirring shaft 24 drives the stirrer 25 to rotate, thereby stirring the reactants in the reaction tank 1.

[0028] Above the cover plate 19, there is a fixedly connected feeding pipe 26. On one side of the feeding pipe 26, there is a fixedly connected solenoid valve 27. The feeding pipe 26 is connected to the bottom of the cover plate 19. Inside the mounting groove 18, there is a filter box 28. Inside the filter box 28, there is a filter chamber 29. Outside the filter box 28, there are also arrayed filter frames 30. The filter frames 30 are all slidably connected to the filter box 28.

[0029] Each filter rack 30 has a filter screen 32 fixedly installed at its inner bottom. Each filter box 28 also has a fixedly connected collection pipe 31 on one side. When the ethanol liquid to be filtered flows into the filter chamber 29 through the connecting pipe 16, the ethanol liquid is then filtered by the four filter racks 30 and flows out through the collection pipe 31. The filtered impurities remain on the filter screen 32 inside the filter rack 30.

[0030] The working process and principle of this utility model are as follows:

[0031] In use, the ethanol to be processed is first added to the reaction tank 1 through the feed pipe 26. At this time, the reaction temperature in the reaction tank 1 is controlled by adding high-temperature steam or cooling water through the coil inside the jacket 11. Then, the peristaltic pump 20 is started. When the peristaltic pump 20 is started, other chemical solvents required for the reaction are metered and added to the reaction tank 1. Then, the stepper motor 23 is started. The stepper motor 23 drives the stirring shaft 24 to rotate, and the stirring shaft 24 drives the stirrer 25 to rotate, thereby stirring the reactants in the reaction tank 1 and accelerating the reaction. After the reaction is completed, some precipitate is generated at the bottom of the reaction tank 1.

[0032] At this time, the infusion pump 13 is started, and the infusion pump 13 draws out the ethanol liquid and reaction precipitate in the reaction tank 1, and then delivers them to the three-way valve 15 through the connecting pipe 14. At this time, the ethanol liquid flows into the corresponding filter chamber 29 through the connecting pipe 16 on one side of the three-way valve 15 for filtration. The filtered ethanol liquid flows out through the collecting pipe 31. After one of the filter frames 30 is blocked, the three-way valve 15 is started to change the flow direction of the ethanol liquid, so that the ethanol liquid flows into the other filter chamber 29 for filtration. At this time, the filtration operation of the ethanol liquid can be continuously performed, thereby greatly improving the filtration efficiency of the ethanol liquid.
