[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, a stirring device for industrial enzyme preparation production includes a tank body 1, the bottom of the tank body 1 is provided with an outer channel steel 11 for reinforcement, which increases the contact area between the tank body 1 and the ground and improves the stability during operation. The top of the tank body 1 is sealed and connected with a cover plate 12, and the cover plate 12 is detachably connected to the tank body 1 up and down. A feed pipe 13 is passed through the cover plate 12, and a discharge pipe 14 connected to the interior of the tank body 1 is provided on one side of the tank body 1. An observation window 15 is provided on the side wall of the tank body 1, and a motor 3 is installed on the upper end of the cover plate 12 through a bracket 2. The output shaft of the motor 3 is connected to the cover plate 12 through a sealed bearing. The bracket 2 includes two L-shaped fixing frames 21, and the two fixing frames 21 are respectively provided with assembly plates 22. A reinforcing plate 23 is commonly connected between the two fixing frames 21, and the assembly plate 22 and the reinforcing plate 23 are both connected to the side wall of the motor 3.

[0026] The output shaft of the motor 3 extends into the tank body 1 and is connected to the conveying rod 4 through a coupling. The conveying rod 4 includes a vertically arranged screw shaft 41. The top of the screw shaft 41 is coaxially fixedly connected to a transmission rod 44. The upper end of the transmission rod 44 is connected to the output shaft of the motor 3 through a coupling. The bottom of the screw shaft 41 is coaxially connected to a bearing seat 45. The bottom of the bearing seat 45 is fixedly connected to the bottom inner wall of the tank body 1. The matched bearing seat 45 can make the screw shaft 41 rotate smoothly. After starting the motor 3, the output shaft of the motor 3 will drive the screw shaft 41 to rotate synchronously through the transmission rod 44.

[0027] like Figure 5 As shown, a spiral blade 42 is provided on the spiral shaft 41, and an extension plate 43 is provided at one end of the spiral blade 42 away from the spiral shaft 41. A delivery pipe 5 is sleeved on the delivery rod 4, and a plurality of support legs 51 are obliquely provided on the inner bottom of the tank body 1. The tops of the plurality of support legs 51 are fixedly connected to the side walls of the delivery pipe 5. It should be noted that due to the fixation of the plurality of support legs 51, there is a certain gap between the delivery pipe 5 and the bottom of the tank body 1 when installed. Therefore, when the spiral shaft 41 drives the spiral blade 42 to rotate, the fermentation liquid can enter the delivery pipe 5 from the bottom of the delivery pipe 5. As the spiral blade 42 rotates, a continuous chamber is formed between it and the inner wall of the delivery pipe 5, which can drive the fermentation liquid to be transported upward. Under the action of the extension plate 43 on the edge of the spiral blade 42, in the process of lifting the fermentation liquid upward, it can effectively avoid the backflow of the liquid and the reduction of the delivery efficiency.

[0028] like Figure 4As shown, a guide plate 52 is provided at the top of the delivery pipe 5, and a plurality of arc-shaped grooves 53 are opened on the circumference of the guide plate 52. Furthermore, after the fermentation liquid is transported to the top of the delivery pipe 5, it will flow along the surface of the guide plate 52. Affected by the rotation direction of the spiral blade 42, the flowing fermentation liquid maintains the same direction, and a portion of the liquid will enter the arc-shaped grooves 53 opened on the guide plate 52. Since the arc-shaped grooves 53 are at opposite angles to the liquid flow direction, a certain impact force can be offset between the liquids, thereby reducing the flow rate of the fermentation liquid dripping from the edge of the guide plate 52 and reducing the foam generated by the collision with the liquid surface below.

[0029] like Figure 3 As shown, a top plate 6 is provided above the conveying rod 4, the upper surface of the guide plate 52 is provided as an arc-shaped surface, the top plate 6 is provided as an arc-shaped plate, and the diameter of the top plate 6 is larger than the diameter of the guide plate 52, the top plate 6 is connected through the transmission rod 44, and the upper end of the top plate 6 is connected to the lower surface of the cover plate 12 through a plurality of connecting rods. Furthermore, the provided top plate 6 can better guide the fermentation liquid, ensure that the fermentation liquid transported to the top of the conveying pipe 5 flows along the surface of the guide plate 52, and ensure that the fermentation liquid inside the tank body 1 is fully circulated and stirred.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
