A spiral blade 72 is fixedly installed on the surface of the transmission rod 71, and a rod sleeve 73 is fixedly connected to the outer side of the spiral blade 72. The surface of the rod sleeve 73 is fixedly connected to a stirring blade 74, and the number of the stirring blades 74 is several.

[0024] As a technical optimization solution of the present invention, through the setting of the stirring component 7, the materials inside the fermentation tank body 3 can be mixed evenly during the fermentation process, thereby accelerating the biological reaction and achieving a faster and better reaction effect, thereby avoiding the situation where the fermentation quality is reduced due to uneven materials inside the fermentation tank body 3.

[0025] refer to Figure 4 The cleaning assembly 8 includes a high-pressure water pump 81, which is fixedly connected to the right side of the top of the fermentation tank body 3. The output end of the high-pressure water pump 81 is connected to a three-way joint 82. The front and rear sides of the three-way joint 82 are connected to a water spray pipe 83. The lower end of the water spray pipe 83 passes through the interior of the fermentation tank body 3 and is connected to a spray ball 84. The surface of the rod sleeve 73 is fixedly connected to a fixed rod 85. There are several fixed rods 85. The outer side of the fixed rod 85 is fixedly connected to a scraper 86. The outer side of the scraper 86 is in contact with the inner wall of the fermentation tank body 3.

[0026] As a technical optimization solution of the present invention, through the setting of the cleaning component 8, the inner wall of the fermentation tank body 3 can be cleaned after the fermentation of the material inside the fermentation tank body 3 is completed and discharged through the discharge pipe 6, thereby preventing the material in the fermentation tank body 3 from adhering to the inner wall of the fermentation tank body 3 during the fermentation process, resulting in material waste.

[0027] refer to Figure 1 The top of the feed pipe 5 and the bottom of the discharge pipe 6 are both threadedly connected with a sealing cover 9, which is used in conjunction with the fermentation tank body 3.

[0028] As a technical optimization solution of the present invention, the sealing cover 9 can be provided to seal the feed pipe 5 and the discharge pipe 6, thereby preventing the material inside the fermentation tank body 3 from coming into contact with the outside air during the fermentation process, which may lead to fermentation failure.

[0029] refer to Figure 3 The top of the rod sleeve 73 is fixedly connected with a defoaming stirrer 10 , which is used in conjunction with the stirring assembly 7 .

[0030] As a technical optimization solution of the present invention, the defoaming agitator 10 is provided to eliminate the foam generated by stirring the material inside the fermentation tank body 3 during the fermentation process, thereby avoiding the situation where the foam generated by stirring the material inside the fermentation tank body 3 during the fermentation process affects the fermentation efficiency.

[0033] refer to Figure 3 A disc turbine agitator 13 is fixedly mounted on the bottom of the surface of the transmission rod 71 , and the disc turbine agitator 13 is used in conjunction with the stirring assembly 7 .

[0034] As a technical optimization solution of the present invention, the disc turbine agitator 13 is set to stir the material that settles to the bottom of the inner wall of the fermentation tank body 3 as the fermentation time increases, thereby preventing the material in the fermentation tank from settling to the bottom of the fermentation tank over time, resulting in the inability to smoothly lift the thicker material settled at the bottom of the fermentation tank body 3 to the preset position through the spiral blades 72, resulting in a decrease in fermentation efficiency.

[0035] The working principle and use process of the present invention are as follows: when in use, the user first adds the material into the interior of the fermentation tank body 3 through the feeding pipe 5, then seals the feeding pipe 5 through the sealing cover 9, starts the motor 4, and the output end of the motor 4 drives the transmission rod 71 to start rotating. When the transmission rod 71 rotates, it drives the disc turbine agitator 13 to start rotating to prevent the material from settling at the bottom of the inner wall of the fermentation tank body 3. The transmission rod 71 drives the spiral blade 72 to start rotating. When the spiral blade 72 rotates, it moves the material at the bottom of the fermentation tank body 3 to the top of the fermentation tank body 3, thereby improving the mixing efficiency of the material. When the spiral blade 72 rotates, it drives the rod sleeve 73 to start rotating. When the rod sleeve 73 rotates, it drives the stirring blade 74, the disinfection The foaming stirrer 10 and the fixed rod 85 start to rotate, and the stirring blades 74 stir the material inside the fermentation tank body 3 when they rotate. The defoaming stirrer 10 eliminates the foam generated during the stirring process when it rotates. The fixed rod 85 drives the scraper 86 to start rotating when it rotates to prevent the material from adhering to the inner wall of the fermentation tank body 3. After the fermentation of the material inside the fermentation tank body 3 is completed, the sealing cover 9 of the discharge pipe 6 is opened and the material is discharged. After the material is discharged from the fermentation tank body 3, the high-pressure water pump 81 is started. The high-pressure water pump 81 sprays water into the fermentation tank body 3 through the three-way joint 82, the water spray pipe 83, and the spray ball 84 to clean the stirring component 7 and the inner wall of the fermentation tank body 3, thereby achieving an efficient stirring effect.

[0036] To sum up: the stirring device for the fermentation tank, through the fixed frame 1, support column 2, fermentation tank body 3, motor 4, feed pipe 5, discharge pipe 6, stirring assembly 7, transmission rod 71, spiral blade 72, rod sleeve 73, stirring fan blade 74, cleaning assembly 8, high-pressure water pump 81, T-joint 82, water spray pipe 83, spray ball 84, fixed rod 85, scraper 86, sealing cover 9, defoaming stirrer 10, limiting ring 11, limiting frame 12, disc turbine stirrer 13, solves the problem that in the original equipment, during the fermentation process, the material in the fermentation tank will settle to the bottom of the fermentation tank or adhere to the inner wall of the fermentation tank with the increase of time, and the original equipment cannot smoothly lift the thicker material settled at the bottom of the fermentation tank to the preset position through the spiral blade, resulting in reduced fermentation efficiency, and the material attached to the inside of the fermentation tank will cause raw material waves after the fermentation is completed.
