For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0032] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in detail below with the help of the drawings.

[0033] As Figure 1 The present application embodiment provides a single shaft type dehydration fermentation equipment, including warehouse body 10 and rotating shaft 20, for clear indication, Figure 1 The upper warehouse plate in the warehouse body 10 is removed, so that the internal structure is visible.

[0034] The dehydration warehouse 11 and the fermentation warehouse 12 are separated in the warehouse body 10, and the rotating shaft 20 penetrates the dehydration warehouse 11 and the fermentation warehouse 12. It can be understood that, in order to realize the rotation of the rotating shaft 20, the rotating shaft 20 is connected with the driving part 21. Single rotating shaft 20 and single driving part 21 make the cost of the equipment compared with the equipment of two rotating shafts 20 and two driving parts 21 is lower, and the dehydration and fermentation functions are integrated, compared with two equipment for realizing two functions separately, the floor area is also smaller, especially without intermediate conveying equipment, such as shaftless screw conveyor to convey material, further reduce the cost and floor area of the whole fermentation system, and its installation is more convenient.

[0035] To realize dehydration, an extrusion dehydration assembly 22 is arranged on the rotating shaft 20 in the dehydration bin 11, and is used to rotate and extrude the material under the driving of the rotating shaft 20. To improve the fermentation effect, a stirring assembly 23 is arranged in the fermentation bin 12, and is arranged on the rotating shaft 20 in the fermentation bin 12. The stirring assembly 23 is driven by the rotating shaft 20 to stir the material in the fermentation bin 12, so that the material in each position is uniformly fermented. As shown in Figure 3 The extrusion dehydration assembly 22 can be a helical rotating blade with gradually decreasing pitch. The material in the dehydration bin 11 is pushed along the axial direction under the pushing of the helical rotating blade. During the advancing process, the material is subjected to the action of the changing pitch, and a huge extrusion force is formed, so that the material is mechanically dehydrated under the action of the external force. The stirring assembly 23 can be a plurality of stirring paddles distributed along the axial direction of the rotating shaft 20.

[0036] As shown in Figure 2 In some embodiments, a communication port 13 is arranged between the dehydration bin 11 and the fermentation bin 12 to realize the communication between the two bins. The communication port 13 is arranged in the direction in which the material is pushed by the extrusion dehydration assembly 22, so that the material can be conveyed by the extrusion pushing of the extrusion dehydration assembly 22 without the intermediate conveying equipment. The dehydration and fermentation are integrated in one device, the installation complexity is reduced, the floor area is reduced, and the cost is reduced.

[0037] In some embodiments, the communication port 13 is arranged on the axis of the rotating shaft 20, so that the rotating shaft 20 can pass through the partition plate between the dehydration bin 11 and the fermentation bin 12 through the communication port 13, facilitating the installation of the rotating shaft 20. At the same time, most of the material is concentrated near the rotating shaft 20. The communication port 13 is arranged on the axis of the rotating shaft 20, facilitating the passage of the material and improving the smoothness of the material flow.

[0038] In some embodiments, the device further comprises a blocking mechanism arranged near the communication port 13 and used to close or open the communication port 13. The opening and closing of the communication port 13 between the dehydration bin 11 and the fermentation bin 12 is controlled by the blocking mechanism, so as to avoid the material in the dehydration bin 11 from entering the fermentation bin 12 before reaching the preset dehydration rate, and to ensure the dehydration effect. At the same time, it also avoids the backflow of the material in the fermentation bin 12 to the dehydration bin 11, and ensures the fermentation effect. The blocking mechanism can be manually controlled or intelligently controlled according to the process parameters, or can be automatically opened and closed by the material pushed in the dehydration bin 11.

[0039] As shown in Figure 3As shown, in some embodiments, the blocking mechanism comprises a blocking door 30 matched with the communication port 13, the blocking door 30 is slidingly arranged on the rotating shaft 20, facilitating the installation of the blocking door 30, and the blocking door 30 is connected with a reset member 31, the blocking door 30 closes the communication port 13 under the action of the reset member 31, can be accurately reset, and improves the working stability of the blocking mechanism.

[0040] In some embodiments, the reset member 31 is a spring, the reset member 31 is sleeved on the rotating shaft 20, and one end thereof abuts against the blocking door 30, which is simple to install, low in cost, and stable in reset effect. Since the material in the dewatering bin 11 also pushes the material during extrusion, as the material reaching the blocking door 30 becomes more and more, the pushing force thereof is greater than the pushing force of the spring on the blocking door 30, the blocking door 30 moves towards the direction of the fermentation bin 12, thereby opening the communication port 13, and the material enters the fermentation bin 12; as the material reaching the blocking door 30 becomes less and less, the pushing force thereof is less than the pushing force of the spring on the blocking door 30, the blocking door 30 moves towards the direction of the dewatering bin 11, thereby closing the communication port 13.

[0041] In some embodiments, a limiting block 32 is arranged on the rotating shaft 20, and the other end of the reset member 31 abuts against the limiting block 32, especially in the case that the reset member 31 is a spring, the movement of the other end of the spring is limited by the limiting block 32, which is convenient to install, stable in limiting effect, and low in cost.

[0042] In some embodiments, a screen cylinder 40 in communication with the communication port 13 is arranged in the dewatering bin 11, and the extrusion dewatering assembly 22 is arranged in the screen cylinder 40. After the material is extruded and dewatered by the extrusion dewatering assembly 22, the water thereof drops through the screen cylinder 40, thereby separating the dry material and the water.

[0043] In some embodiments, a feeding hopper 50 is in communication with the end of the screen cylinder 40 away from the communication port 13, which facilitates the material to enter the dewatering bin 11, and makes the material pass through a longer dewatering path as possible, thereby improving the dewatering effect.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
