Description

Technical Field

[0001] This utility model relates to the field of ethanol fermentation technology, and in particular to a fuel ethanol fermentation reactor. Background Technology

[0002] In the process of fuel ethanol fermentation, traditional fermentation equipment has some shortcomings in terms of stirring and liquid addition. Stirring is crucial to the fermentation process, as it can promote full contact between microorganisms and nutrients, improve utilization efficiency, maintain the uniformity of environmental conditions inside the tank, and increase dissolved oxygen to meet the respiration requirements of microorganisms.

[0003] However, if the liquid addition point is too high, the collision between the liquid and the liquid at the bottom of the tank can cause splashing, affecting fermentation stability. Furthermore, existing stirring devices typically require additional electricity, which not only increases the complexity and maintenance difficulty of the equipment but also raises production costs. Therefore, ensuring stable liquid addition while maintaining slow stirring is crucial. Thus, a fuel ethanol fermentation reactor is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fuel ethanol fermentation reaction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a fermentation tank, a liquid addition pipe fixedly connected to the top of the fermentation tank for adding ethanol fermentation liquid into the fermentation tank, a support frame fixedly connected inside the fermentation tank, a fixed seat fixedly connected to the support frame, and a fixed rod rotatably connected inside the fixed seat; it also includes a stirring assembly disposed on the fixed rod, the stirring assembly being used to drive a stirring blade disposed at the bottom end of the fixed rod by water flow.

[0006] As a further description of the above technical solution: the stirring component includes a receiving plate fixedly connected to the top of the fixed rod, and a downflow cavity opened in the fixed rod. The receiving plate has an inlet hole communicating with the downflow cavity. The outer edge of the receiving plate gradually slopes towards the inlet hole. The receiving plate has a conical structure and is located below the liquid addition pipe. When the liquid enters the fermentation tank, it first falls on the receiving plate. The receiving plate introduces the liquid into the fixed rod, and the fixed rod directly introduces the liquid into the bottom of the fermentation tank. The advantage of this design is that the receiving plate can prevent the liquid from falling from too high and splashing, which would affect fermentation and other problems.

[0007] As a further description of the above technical solution: an external expansion shell is fixedly connected to the fixed rod near its bottom end. The external expansion shell includes an installation cavity, which is connected to the downstream cavity. A rotating rod is rotatably connected to the installation cavity. Both ends of the rotating rod extend outward and are fixed to the stirring blade. A drive blade located in the downstream cavity is fixedly connected to the rotating rod. The drive blade in the installation cavity is located below the downstream cavity. Since the drive blade is located at the bottom of the downstream cavity, when liquid is supplied to the fixed rod, the liquid drives the drive blade to rotate. The drive blade drives the stirring blade to rotate through the rotating rod, thereby using the water flow to stir the liquid.

[0008] As a further description of the above technical solution: the fixed rod is provided with a shaft, the rotating rod is rotatably connected to the fixed rod through the shaft, the bottom end of the fixed rod is provided with a drainage hole, and the bottom side wall of the fixed rod is provided with several overflow holes. The several overflow holes and the drainage holes are all connected to the downstream cavity. The water flowing out of the downstream cavity can be discharged through the overflow holes and the drainage holes together, which can improve the outflow efficiency and reduce the impact.

[0009] As a further description of the above technical solution: the support frame is at least a pair, and the pair of support frames are respectively close to the receiving plate and close to the stirring blade. The pair of support frames are arranged opposite to each other on the fixed rod to improve the stability of the fixed rod.

[0010] This utility model has the following beneficial effects:

[0011] 1. Compared with the prior art, this fuel ethanol fermentation reactor, by setting up a stirring component, when the liquid enters the fermentation tank, it first falls onto the receiving plate. The receiving plate guides the liquid into the fixed rod, and the fixed rod guides the liquid directly into the bottom of the fermentation tank. This allows the receiving plate to prevent the liquid from falling from too high and splashing, which would affect the fermentation process.

[0012] 2. Compared with the prior art, this fuel ethanol fermentation reactor, by setting up a drive blade and a stirring blade, when the ethanol fermentation liquid enters the fixed rod and is conveyed downward, the liquid will drive the drive blade to rotate. The drive blade drives the stirring blade to rotate through the rotating rod, thereby using the water flow to stir the liquid. No additional electric drive is required, which is convenient for maintenance and reduces the operating cost. Attached Figure Description

The receiving plate 5 has an inlet hole 6 communicating with the downflow chamber 15. The outer edge of the receiving plate 5 gradually slopes towards the inlet hole 6. The receiving plate 5 has a conical structure and is located below the liquid addition pipe 16. When the liquid enters the fermentation tank 1, it first falls on the receiving plate 5. The receiving plate 5 introduces the liquid into the fixed rod 4, and the fixed rod 4 introduces the liquid directly into the bottom of the fermentation tank 1. The advantage of this design is that the receiving plate 5 can prevent the liquid from falling from too high and splashing, which would affect fermentation.

A rotating rod 8 is rotatably connected to the mounting cavity 12. The two ends of the rotating rod 8 extend outward and are fixed to the stirring blade 9. A drive blade 10 located in the downstream cavity 15 is fixedly connected to the rotating rod 8. The drive blade 10 in the mounting cavity 12 is located below the downstream cavity 15. Since the drive blade 10 is located at the bottom of the downstream cavity 15, when liquid is supplied to the fixed rod 4, the liquid drives the drive blade 10 to rotate. The drive blade 10 drives the stirring blade 9 to rotate through the rotating rod 8, thereby using the water flow to stir the liquid. No additional electric drive is required, which is convenient for maintenance and reduces the cost of use.

[0025] The bottom end of the fixed rod 4 is provided with a drainage hole 13, and the bottom side wall of the fixed rod 4 is provided with several overflow holes 14. The overflow holes 14 and the drainage holes 13 are all connected to the downstream cavity 15. The water flowing out of the downstream cavity 15 can be discharged through the overflow holes 14 and the drainage holes 13 together, which can improve the outflow efficiency and reduce the impact.

[0027] Working principle: When in use, the ethanol fermentation liquid is added into the fermentation tank 1 through the liquid addition pipe 16. When the liquid enters the fermentation tank 1, it first falls onto the receiving plate 5. The receiving plate 5 guides the liquid into the fixing rod 4, and the fixing rod 4 guides the liquid directly into the bottom of the fermentation tank 1. The advantage of this setting is that the receiving plate 5 can prevent the liquid from falling from too high and splashing, which would affect the fermentation.
