Ethanol microbial seed and vitamin nutrient substrate mixing structure

Abstract

This invention provides a mixing structure for ethanol microbial seeds and vitamin nutrient substrates, effectively solving the problem that existing equipment cannot meet the requirements of biosynthetic ethanol processes and that excessive mixing force easily damages the microorganisms. The technical solution includes an upward-opening container with a circular shell fixed to its upper side. The circular shell is fixed to the container opening by multiple fixing rods. Multiple feed inlets are located at the upper end of the circular shell. A turntable is rotatably connected to the lower side plate of the circular shell, and multiple circumferentially distributed spiral tubes are fixed to the lower end of the turntable. The material enters the cavity of the circular shell through the multiple feed inlets and flows downwards along the multiple spiral tubes into the container cavity, finally overflowing from the upper opening of the container. This invention has an ingenious structure that enables the mixing of bacterial seeds with vitamins and nutrient solutions while minimizing damage to the bacterial seeds during mixing, thus well meeting the needs of biosynthetic ethanol production.

Description

Technical Field

[0001] This utility model relates to the field of biosynthetic ethanol production technology, and in particular to a mixed structure of ethanol microbial seeds and vitamin nutrient matrix. Background Technology

[0002] A major advantage of the industrial syngas bio-fermentation technology for ethanol production is the 93% conversion rate of syngas to ethanol. Bacteria can convert over 99% of the CO, over 95% of the CO2, and over 95% of the H2 in the syngas into the product in a single fermentation tank. Before the industrial syngas can enter the fermentation tank, seeds, vitamin tanks, and nutrient tanks need to be mixed and reacted in a seed reactor, and then the mixed nutrient solution is transported to the fermentation tank. Traditional stirring equipment is often used in the mixing process of seeds with vitamins and nutrients, such as the sand and gravel aggregate mixing device (patent documents CN120326786A), material coating mixing device (CN117205775A), and stirring device and mixing equipment (CN114797557A). These devices often require modifications to the stirring mechanism. While such mechanisms require additional power, the mixing of seeds with vitamins and nutrients in liquids does not require such high-intensity stirring to avoid damaging the microorganisms. Therefore, existing equipment cannot meet the production process requirements for biosynthetic ethanol.

[0003] To address the aforementioned issues, a hybrid structure of ethanol-based microbial seeds and vitamin nutrient substrate is proposed. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mixed structure of ethanol microbial seeds and vitamin nutrient matrix, which effectively solves the problems that existing equipment cannot meet the requirements of biosynthesis ethanol process and that the large mixing force can easily cause damage to the strain.

[0005] The technical solution includes an upward-opening container with a disc shell fixed to the upper side. The disc shell is fixed to the container opening by multiple fixing rods. The upper end of the disc shell has multiple feed ports. A turntable is rotatably connected to the lower side plate of the disc shell. Multiple spiral tubes evenly distributed in a circle are fixed to the lower end of the turntable. The material enters the disc shell cavity through the multiple feed ports and flows downward along the multiple spiral tubes into the container cavity, finally overflowing from the upper port of the container.

[0006] Furthermore, the outer edge of the turntable is folded upwards, and a bearing with a built-in sealing ring is installed between the turntable and the lower side plate of the disc shell.

[0007] Furthermore, the upper end of the container is constricted, and the structure composed of multiple spiral tubes forms a conical cage structure.

[0008] This invention has a clever structure that enables the mixing of bacterial seeds with vitamins and nutrient solutions, while minimizing damage to the bacterial seeds during stirring, thus effectively meeting the needs of biosynthetic ethanol production. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 4 The present invention includes an upward-opening container 1, a disc shell 2 fixed to the upper side of the container 1, the disc shell 2 and the opening edge of the container 1 being fixed together by multiple fixing rods, the upper end of the disc shell 2 having multiple feed inlets 3, a turntable 4 rotatably connected to the lower side plate of the disc shell 2, and multiple circumferentially distributed spiral tubes 5 fixed to the lower end of the turntable 4; the material enters the cavity of the disc shell 2 through the multiple feed inlets 3, and enters the cavity of the container 1 along the multiple spiral tubes 5, and finally overflows from the upper opening edge of the container 1.

[0015] To install the turntable 4, the outer edge of the turntable 4 is folded upward, and a bearing with a built-in sealing ring is installed between the turntable 4 and the lower side plate of the disc shell 2.

[0016] To achieve more thorough mixing, the upper end of the container 1 is constricted, and the structure composed of multiple spiral tubes 5 is a conical cage structure.

[0017] It is worth noting that a metering pump with metering function should be used when pumping materials, firstly for accurate metering and proportioning, and secondly to prevent water backflow when the material is pumped downwards.

[0018] In use, metering pumps are used to connect the inlet 3 to the inlet of the bacterial culture, vitamin solution, and nutrient solution. Each metering pump simultaneously pumps the multi-component substances into the chamber of the disc shell 2 to achieve initial mixing. Then, the solution after initial mixing enters the chamber of container 1 through multiple spiral tubes 5. At the same time, the multiple spiral tubes 5 rotate under the reaction force to stir and mix the mixture in the chamber of container 1, that is, secondary mixing. Finally, the mixed liquid overflows from the upper port of container 1.

[0019] In this structure, the multi-component materials move downward along the spiral tube 5, causing the multiple spiral tubes 5 to rotate. At this time, the multiple spiral tubes 5 play a stirring role, realizing the mixing of the various components in the container 1 cavity.

[0020] This invention has a clever structure that enables the mixing of bacterial seeds with vitamins and nutrient solutions, while minimizing damage to the bacterial seeds during stirring, thus effectively meeting the needs of biosynthetic ethanol production.
