Description

Technical Field

[0001] This utility model relates to the field of reaction equipment, and in particular to a corn syrup feeding tank. Background Technology

[0002] Corn steep liquor feed tanks are key equipment in the fermentation industry, mainly used to dynamically replenish nutrients (such as carbon sources, nitrogen sources, growth factors, etc.) during microbial fermentation to optimize the fermentation process and increase product yield.

[0003] Due to the high viscosity, solids content, and organic matter in corn syrup, it is extremely prone to scale buildup, microbial growth, or blockage. Therefore, regular cleaning and maintenance of the corn syrup replenishment tank are essential to ensure normal equipment operation, maintain production efficiency, and product quality.

[0004] Existing corn syrup feeding tanks all adopt an integral structure, and the inside of the tank is periodically flushed by connecting an external flushing pipe through a flushing port. Due to the large diameter and height of the tank, this cleaning method often has cleaning dead spots, resulting in some scale residue, which affects the normal operation of the equipment and product quality. Utility Model Content

[0005] The purpose of this invention is to provide a corn syrup feeding tank to solve the problems existing in the prior art.

[0006] The purpose of this utility model is achieved as follows: A corn syrup feeding tank includes a tank body, which includes a tank top and a tank body. A base is provided at the center of the tank top, and a stirring drive device is installed on the base. The stirring drive device is connected to a stirring shaft extending into the tank body through a coupling. A first stirrer and a second stirrer are respectively provided at the middle and lower ends of the stirring shaft. The stirring blades of the first stirrer and the second stirrer are each two blades and are staggered. A feed inlet is provided on one side of the tank top. A lifting device is provided around the outer periphery of the tank top. A flange and a sealing gasket are provided at the mating surface of the tank body and the tank top. A jacket is provided outside the tank body. A steam inlet is provided on the top side of the jacket and a condensate outlet is provided at the bottom. A discharge port is provided at the bottom of the tank body.

[0007] This utility model's corn syrup feeding tank, through the installation of a first and second agitator, achieves gentle stirring with low shear force, preventing damage to the corn syrup components and effectively preventing sedimentation and stratification, ensuring uniform suspension of the syrup and reducing tank scaling. Simultaneously, the jacketed design heats and maintains the temperature of the corn syrup, reducing its viscosity, improving its fluidity, and inhibiting microbial growth, thereby reducing the frequency of equipment cleaning. Furthermore, when tank cleaning is required, simply lifting the tank top to a certain height with a hoist allows for thorough rinsing of the tank's inner wall and agitators, resulting in high cleaning efficiency and excellent cleaning effect, effectively ensuring normal equipment operation, maintaining production efficiency, and product quality.

[0008] As a further improvement of this invention, 4-6 sets of vertical baffles are provided around the inner wall of the tank to disrupt the rotating flow field, preventing the slurry from forming a concentric rotating flow with the stirring blades, thus improving the mixing effect and preventing slurry stratification. In addition, the vertical baffles increase the contact frequency between the slurry and the heat transfer surface of the tank, improving heating efficiency, ensuring uniform temperature distribution, preventing localized overheating or underheating zones, ensuring stable corn slurry viscosity, and facilitating subsequent pumping and precise replenishment. A 5-10mm gap is provided between the vertical baffles and the inner wall of the tank to prevent slurry residue or scale buildup.

[0009] As a further improvement of this utility model, the stirring drive device is a vertical circular arc tooth cylindrical worm gear reducer, which has a compact structure, saves space, and can stably output high torque to cope with the high resistance during corn slurry stirring. Furthermore, the unidirectional transmission characteristic (reverse self-locking) of the worm gear prevents the stirring shaft from reversing due to the gravity of the material when the machine stops, protecting the reducer and transmission system. At the same time, the progressive meshing method of the circular arc tooth worm gear can reduce transmission impact and vibration, and reduce corn slurry splashing or foaming caused by mechanical vibration during stirring.

[0010] As a further improvement of this utility model, a first thermometer tube is inserted into the lower side of the tank body, and a second thermometer tube is provided on the upper side of the jacket, which facilitates stable monitoring in real time.

[0011] As a further improvement of this utility model, an observation mirror is provided on one side of the tank top to facilitate observation of the working status inside the tank at any time.

[0012] As a further improvement of this utility model, a support is provided at the bottom of the tank body, which provides stable support for the tank body while leaving sufficient space for the connection of the bottom discharge port, condensate outlet, etc., to the corresponding pipelines, facilitating operation. Connecting flanges are provided at the feed port, discharge port, steam inlet, and condensate outlet to improve connection efficiency and reliability. Attached Figure Description

[0015] like Figure 1 The corn syrup feeding tank shown includes a tank body. The tank body includes a tank top 1 and a tank body 2.

[0016] A base 3 is located at the center of the tank top 1, and a stirring drive device 4 is installed on the base 3. The stirring drive device 4 is connected to the stirring shaft 5 that extends into the tank body through a coupling 6. A feed inlet 7 is provided on one side of the tank top 1, and an observation mirror 8 is provided on the other side for easy observation of the working status inside the tank.

[0017] The mating surfaces of the tank body 2 and the tank top 1 are equipped with flanges 9 and sealing gaskets 10, which can be detachably connected by bolts and nuts. The outer periphery of the tank top 1 is equipped with a lifting device 11, so that the tank top 1 can be easily lifted by a lifting device when in contact with the tank body 2.

[0018] The tank body 2 is equipped with a jacket 12. The top side of the jacket 12 is provided with a steam inlet 13 and the bottom is provided with a condensate outlet 14. By setting the jacket 12, the corn syrup is heated and kept warm, which reduces its viscosity, improves its fluidity, and inhibits the growth of microorganisms, thereby reducing the frequency of equipment cleaning.

[0019] The tank body 2 has a discharge port 15 at its bottom. Four to six sets of vertical baffles 16 are arranged around the inner wall of the tank body 2 to disrupt the rotating flow field, preventing the slurry from forming a concentric rotating flow with the stirring blades, improving mixing efficiency, and preventing slurry stratification. Furthermore, the vertical baffles 16 increase the contact frequency between the slurry and the heat transfer surface of the tank body 2, improving heating efficiency, ensuring uniform temperature distribution, preventing localized overheating or low-temperature zones, ensuring stable corn slurry viscosity, and facilitating subsequent pumping and precise replenishment. A 5-10mm gap is maintained between the vertical baffles 16 and the inner wall of the tank to prevent slurry residue or scale buildup. A first thermometer tube 17 is inserted into the lower side of the tank body 2, and a second thermometer tube 18 is installed on the upper side of the jacket 12 for convenient real-time stable monitoring. A support 19 is provided at the bottom of the tank body 2, providing stable support while allowing sufficient space for connections to the bottom discharge port 15, condensate outlet 14, and other corresponding pipelines, facilitating operation. The feed inlet 7, the discharge outlet 15, the steam inlet 13, and the condensate outlet 14 are all equipped with connecting flanges to improve connection efficiency and reliability.

[0020] In this embodiment, the stirring drive device 4 is a vertical circular arc tooth cylindrical worm gear reducer, which has a compact structure, saves space, and can stably output high torque to cope with the high resistance during corn syrup stirring. Furthermore, the unidirectional transmission characteristic (reverse self-locking) of the worm gear prevents the stirring shaft 5 from reversing due to material gravity when the machine stops, protecting the reducer and transmission system. Simultaneously, the progressive meshing method of the circular arc tooth worm gear reduces transmission impact and vibration, minimizing corn syrup splashing or foaming caused by mechanical vibration during stirring. A first stirrer 20 and a second stirrer 21 are respectively provided at the middle and lower ends of the stirring shaft 5. Both the first stirrer 20 and the second stirrer 21 have two stirring blades, which are staggered. The diameter of the first stirrer 20 is less than half the inner diameter of the tank body 2, resulting in gentle stirring and low shear force, preventing damage to the corn syrup components.

[0021] In this embodiment, when the corn syrup feeding tank needs cleaning, the top 1 of the tank is simply lifted to a certain height using a lifting device to thoroughly rinse the inner wall of the tank body 2 and the agitator. This method is highly efficient and effective, ensuring normal operation of the equipment and maintaining production efficiency and product quality.

[0022] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
