[0040] Please refer to Figures 1 to 3 This utility model provides a push-flow agitator, including a housing 1 and an agitator 2; the housing 1 is provided with a reaction chamber 11; the agitator 2 includes a rotating shaft 21 and a plurality of blades 22, the rotating shaft 21 is rotatably mounted in the reaction chamber 11, the plurality of blades 22 are all connected to the rotating shaft 21 and are spirally distributed along the axis of the rotating shaft 21, and each blade 22 includes a connecting plate 221 and a cutting plate 222, one end of the connecting plate 221 is connected to the rotating shaft 21, and one end of the cutting plate 222 is connected to the connecting plate 221 and is staggered with the connecting plate 221.

[0041] In this embodiment, the rotating shaft 21 rotates, driving multiple blades 22 to rotate. The cutting plate 222 and the connecting plate 221 are staggered, thereby shearing the material and chopping the solid material, making the material in the reaction chamber 11 more thoroughly mixed. Furthermore, the multiple blades 22 are spirally distributed on the rotating shaft 21, pushing the material while stirring and mixing. This allows the material to swirl towards the jet, shearing, mixing, and conveying the material, achieving stable, horizontal flow. The horizontal flow agitator is used for stirring fermentation raw materials with a high concentration of solids up to 35%, and is applied to large-volume flow environments.

[0042] Furthermore, in one embodiment, each of the paddles 22 includes a plurality of cutting plates 222, which are radially spaced along the rotation axis 21. This increases the shearing range of the plurality of paddles 22, allowing for thorough mixing of materials and improving stirring efficiency.

[0043] In another embodiment, the thickness of the cutting plate 222 decreases from the middle to both sides. While ensuring the strength of the cutting plate 222, the two sides of the cutting plate 222 are the same as the cutting edge of the blade, which can easily cut materials, especially solid materials.

[0044] It should be noted that either of the two embodiments described above can be configured, or both can be configured simultaneously. Configuring both simultaneously yields better results. In this embodiment, we will continue to refer to... Figures 1 to 3 Each of the blades 22 includes multiple cutting plates 222, which are radially spaced along the rotation axis 21, and the thickness of each cutting plate 222 decreases from the center to both sides. This not only increases the shearing range of the blades 22, but also allows for easy cutting of materials, ensuring thorough and uniform mixing.

[0045] It should be noted that the extension direction of the connecting plate 221 is not limited. In this embodiment, the connecting plate 221 extends radially along the rotation axis 21.

[0046] Reference Figures 3 to 5 In this embodiment, each cutting plate 222 includes a first end 2221 and a second end 2222 opposite to each other. The first end 2221 is connected to the connecting plate 221, and the second end 2222 is inclined away from the rotation axis 21. The inclination angle of the plurality of second ends 2222 gradually increases in the direction away from the rotation axis 21. Thus, the plurality of cutting plates 222 of each blade 22 have different shearing directions, which can more easily cut solid materials and cut more thoroughly.

[0047] Furthermore, one side of the cutting plate 222 is inclined away from the rotation axis 21; thus, the cutting plate 222 can cut materials more easily.

[0048] Furthermore, referring to Figure 6 The tilt angle of one side of the cutting plate 222 is set as ∠A. In this embodiment, in one of the paddle blades 22, ∠A is the angle between the plane perpendicular to the connecting plate 221 and the plane where the cutting plate 222 is located, 35°≤∠A≤45°.

[0049] In this embodiment, ∠A = 40°, so that the cutting plate 222 can cut the material most easily.

[0050] To strengthen the structure of the blade 22, the blade 22 includes two connecting plates 221, both of which are connected to the rotating shaft 21 and are radially spaced along the rotating shaft 21; the two ends of each connecting plate 221 are connected to the two rotating shafts 21 respectively. This results in a robust structure and extended service life.

[0051] In addition, the blade 22 also includes a base 224, which is connected to the rotating shaft 21, and two connecting plates 221 are connected to the base 224.

[0052] In this embodiment, refer to Figures 3 to 5 In one of the paddle blades 22, the two ends of the plurality of connecting plates 221 are respectively connected to two connecting plates 221. The plurality of connecting plates 221 and the corresponding two connecting plates 221 form a plurality of through grooves 223. The plurality of through grooves 223 are distributed at intervals along the length direction of the corresponding connecting plates 221, so that the material can pass through each of the through grooves 223 during stirring, reducing resistance and improving stability.

[0053] In this utility model, reference is made to Figure 1 and Figure 2 The included angle between two adjacent blades 22 is ∠B, where 40°≤∠B≤50°. Specifically, in this embodiment, ∠B=45°. Thus, the multiple blades 22 are arranged reasonably, improving stirring efficiency while minimizing resistance.

[0054] Continue to refer to Figure 1 and Figure 2In this embodiment, the length direction of the reaction chamber 11 is the same as the axial direction of the rotating shaft 21; the housing 1 also has two cavities 12, which are located on both sides of the radial direction of the rotating shaft 21 and are distributed opposite to each other. Each cavity 12 is connected to both ends of the reaction chamber 11. One cavity 12 is used for feeding, and the other for discharging; thus, the design is reasonable and reduces space occupation.

[0055] It should be noted that in this embodiment, the shell 1 is designed with a brick-concrete structure, which makes the civil construction simpler and faster, the heat preservation effect more obvious, and the high temperature enables the microorganisms in the anaerobic system to degrade and ferment more quickly, reducing the material residence time.

[0056] Reference Figures 1 to 3 In this embodiment, the push-flow agitator further includes a support base 3, which is located in the middle of the rotating shaft 21 and is used to support the rotating shaft 21. This makes the operation of the agitator 2 more stable.

[0057] It should be noted that the present invention does not limit the structure of the support base 3, as long as it can support the rotating shaft 21. In this embodiment, the support base 3 is fixed to the bottom wall of the reaction chamber 11, and the support base 3 includes a bearing. The middle part of the rotating shaft 21 is rotatably connected to the bearing, so as to achieve the function of support without hindering the rotation of the rotating shaft 21.

[0058] Specifically, refer to Figures 1 to 3 In this embodiment, the housing 1 has at least one through hole; one end of the rotating shaft 21 passes through the through hole; the push-flow agitator further includes a support 4, a reducer 5, a motor 6, and at least two bearing seats 7. The support 4 is installed outside the housing 1. The two bearing seats 7 are both wear-resistant bearing seats and are distributed opposite each other along the length of the reaction chamber 11. One of them is installed on the support 4 and corresponds to the through hole, while the other is installed inside the reaction chamber 11. The reducer 5 is installed on the support 4 and is drively connected to the rotating shaft 21. The motor 6 is driven by the reducer 5. The motor 6 drives the reducer 5 to operate, thereby driving the rotating shaft 21 to rotate.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
