DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figures 1 to 5 The utility model provides a technical solution: a mechanical stirring and ventilating fermentation tank, comprising a tank body 1, a pressure gauge 2, a bracket 3 and a jacket 4, the pressure gauge 2 is located at the top of the tank body 1, the bracket 3 is located at the bottom of the tank body 1, the jacket 4 is arranged on the outside of the tank body 1, a motor 5 is arranged on the top of the tank body 1, the output shaft of the motor 5 is fixedly connected with a stirring shaft 6, the top of the tank body 1 is connected with a ventilation pipe 7, one end of the ventilation pipe 7 located in the tank body 1 is fixedly connected with a guide bucket 8, the end of the ventilation pipe 7 is fixedly connected with a connecting column 9, the interior of the connecting column 9 is slidably connected with an extension rod 10, a spring 11 is fixedly connected between the extension rod 10 and the connecting column 9, and the end of the extension rod 10 is fixedly connected with a dispersion plate 12.
[0028] The pressure gauge 2 is used to measure the air pressure in the tank body 1 to prevent the air pressure in the tank body 1 from being too high during the fermentation process. The jacket 4 is provided with a cavity inside, which can be used for cooling. This is a prior art, and its working principle is not described here. When in use, the organic acid and other substances to be fermented are placed in the tank body 1, and then the motor 5 is started. The output shaft of the motor 5 rotates to drive the stirring shaft 6 to rotate, and then the air is introduced into the tank body 1 through the ventilation pipe 7 and the guide bucket 8. The extension rod 10 and the dispersion plate 12 are further extended under the pressure of the gas, driving the spring 11 in an extended state. When the gas hits the dispersion plate 12, it will be dispersed, so that the contact area between the air and the fermentation liquid is larger. At the same time, the dispersion plate 12 can also prevent the fermentation liquid from splashing to the mouth of the ventilation pipe 7 when the stirring shaft 6 is stirred, thereby avoiding further blockage and achieving better ventilation effect.
[0029] Furthermore, the diameter of the dispersion plate 12 is greater than the diameter of the bottom of the guide scoop 8 .
[0030] See also Figure 3, so as to avoid the fermentation liquid with a certain viscosity flying onto the guide bucket 8.
[0031] Furthermore, a scraper 13 is fixedly connected to the top of the stirring shaft 6 , and the scraper 13 is in contact with the bottom of the dispersion plate 12 .
[0032] See also Figure 3 , Figure 4 , Figure 5 The width of the scraper 13 and the dispersion plate 12 is small, and when the stirring shaft 6 rotates, the scraper 13 is driven to rotate, thereby cleaning the fermentation liquid at the bottom of the dispersion plate 12.
[0033] Furthermore, a turbine agitator 14 is provided in the middle of the agitator shaft 6 , and a six-blade flat-plate compound agitator 15 is provided at the end of the agitator shaft 6 .
[0034] See also Figure 4 Assembling two types of agitators on the same agitator shaft 6 will not have a negative impact on the stirring, but on the contrary can improve the stirring efficiency and save power.
[0035] Furthermore, an annular air cushion 16 is provided between the turbine agitator 14 and the six-blade flat-plate compound agitator 15 .
[0036] See also Figure 4 The annular air cushion 16 moves up and down along the stirring shaft 6, which can realize axial stirring in a partial area, fully improving the stirring efficiency and mixing rate, and achieving energy saving and consumption reduction.
[0037] Furthermore, a defoamer 17 is provided inside the tank body 1 and is located 10 cm above the liquid surface.
[0038] See also Figure 2 , Figure 4 The defoamer 17 is located 10 cm above the liquid surface so that it can better contact the bubbles and improve the defoaming effect, so that the bubbles on the liquid surface can be removed more effectively.
[0039] Furthermore, a plurality of baffles 18 are fixedly connected to the inner wall of the tank body 1 , and the baffles 18 are distributed in a circular array with the center of the tank body 1 as the center.
[0040] See also Figure 2The baffle 18 is also provided with cooling fins. In this embodiment, the number of baffles 18 is set to 5. The baffles 18 can form a stirring flow inside the fermentation tank, promote the full mixing of materials, break the flow state of the liquid, and make the materials more evenly mixed together, which is conducive to the reaction during the fermentation process. At the same time, it can also increase the surface area inside the fermentation tank and improve the heat and mass transfer effect. By setting the baffle 18, the contact area between the liquid and the tank wall can be increased, the heat and mass transfer efficiency can be improved, and it is conducive to maintaining constant temperature and uniformity during the fermentation process.
[0041] Furthermore, a coil-tube cooling device 19 is provided inside the tank body 1 .
[0042] See also Figure 2 The fermentation tank has a large capacity and a small specific surface area of the tank body 1. The jacket 4 cannot meet the cooling requirements. The cooling effect of the coil is better. When water is used as the cooling medium, the coil cooling device 19 can achieve a fast and uniform cooling effect, save energy and is easy to control, which is beneficial to improving the efficiency and quality of the fermentation process.
[0043] Furthermore, a discharge port flow control valve 20 is provided at the bottom discharge port of the tank body 1 .
[0044] See also Figure 2 The discharge port flow control valve 20 is provided to achieve the precise discharge amount and avoid waste.
[0045] Furthermore, a control panel 21 is disposed outside the jacket 4 .
[0046] See also Figure 2 The control panel 21 can more accurately control the situation in the fermentation tank body 1, and the operation is simple and easy to control.
[0047] Working principle: When the mechanical stirring ventilated fermentation tank is used, the organic acid and other substances to be fermented are first placed in the tank body 1, and then the water inlet of the jacket 4 and the cooling temperature of the serpentine cooling device 19 are controlled through the control panel 21. After completion, the motor 5 is started through the control panel 21, and the output shaft of the motor 5 rotates to drive the stirring shaft 6 to rotate, and at the same time drives the turbine agitator 14 and the six-blade flat-plate compound agitator 15 to rotate. By controlling the up and down movement of the annular inflatable cushion 16, axial stirring of part of the area is achieved, which fully improves the stirring efficiency and mixing rate.
[0048] During ventilation, air enters the guide bucket 8 from the ventilation pipe 7 and then enters the tank body 1. At the same time, the extension rod 10 and the dispersion plate 12 are further extended under the pressure of the gas, driving the spring 11 to be in an extended state. When the gas hits the dispersion plate 12, it will be dispersed, so that the contact area between the air and the fermentation liquid is larger. In addition, the dispersion plate 12 can also prevent the fermentation liquid from splashing to the mouth of the ventilation pipe 7 when the stirring shaft 6 is stirring. At the same time, when the stirring shaft 6 rotates, it drives the scraper 13 to rotate to clean the viscous liquid at the bottom of the dispersion plate 12.
[0049] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
