Abstract
Description
Technical Field
[0001] This application relates to the technical field of fermentation devices, and particularly to a uniform straw fermentation device. Background Art
[0002] With the continuous development of agricultural production, the treatment of agricultural waste such as straw has become an urgent problem to be solved. Traditional straw fermentation methods mostly use static natural fermentation. Although this method is simple and easy to implement, since straw is prone to stacking during the static process, it causes insufficient internal oxygen, reduces the activity of microorganisms, and further leads to incomplete fermentation, affecting the quality of the final product. Utility Model Content
[0003] The problem to be solved by this application is that the existing straw mainly uses static natural fermentation, but due to the easy stacking of straw during the static process, it causes insufficient internal oxygen, reduces the activity of microorganisms, and further leads to incomplete fermentation.
[0004] To solve the above technical problems, this application provides a uniform straw fermentation device, including a frame for basic support, a tank for fermenting straw is arranged on the upper part of the frame, a discharge port for discharging the fermented straw is arranged directly below the tank, and a stirring assembly for stirring the straw to enable full fermentation and prevent blockage of the discharge port is arranged inside the tank.
[0005] Since the fermentation device of this application is designed with a stirring assembly, it can both perform uniform fermentation stirring operation on the straw through the stirring assembly and perform anti-blocking stirring operation on the discharge port through the stirring assembly, solving the problem that the existing technology mainly uses static natural fermentation for straw, but due to the easy stacking of straw during the static process, it causes insufficient internal oxygen, reduces the activity of microorganisms, and further leads to incomplete fermentation.

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment
[0015] The present application relates to a uniform straw fermentation device. As Figure 1-7 shown, the fermentation device includes a frame 4 for basic support. Above the frame 4, there is arranged a tank body 3 for fermenting straw. Inside the tank body 3, there is arranged a stirring assembly 1 for stirring the straw so that it can be fully fermented. Below the tank body 3, there is arranged a discharge port 6 for discharging the fermented straw. In order to prevent the straw from blocking the discharge port 6 during the fermentation process, the stirring assembly 1 also has the function of preventing blockage and stirring of the discharge port 6. In order to improve the fermentation rate of the straw, on one side of the upper part of the tank body 3, liquid inlets 5 for adding fermentation liquid are symmetrically arranged. In order to effectively control the addition amount of the fermentation liquid and the sealing of the tank body 3, a liquid control valve is added to the liquid inlet 5, and the addition operation of the fermentation liquid is carried out in a timed opening and closing manner. And a feeding port 2 for adding straw is also arranged on the upper part of the tank body 3.
[0016] The stirring assembly 1 includes a motor 7, a shaft rod 8, paddle boards, and a scraping plate 11. The shaft rod 8 is vertically arranged at the central position inside the tank body 3 and is connected thereto through a bearing seat. At the top of the tank body 3, there is a motor 7 connected thereto and capable of driving its rotation. On the side of the shaft rod 8, there are paddle boards sleeved for stirring the straw. In order to perform a sufficient and effective stirring operation on the straw, therefore, the paddle boards are divided into a horizontal board 10 and a vertical board 9. The horizontal board 10 is symmetrically and horizontally arranged on both sides of the shaft rod 8 in a straight plate shape, and the vertical board 9 is arranged in a sickle shape on one side of the horizontal board 10. Thus, by means of the horizontal board 10, the stirring diameter of the paddle boards is expanded, and by means of the vertical board 9, the stirring depth of the paddle boards is expanded to prevent the straw from piling up and fermenting incompletely inside the tank body 3. In order to ensure the impact resistance strength of the paddle boards during the stirring process, therefore, the length dimension ratio of the horizontal board 10 to the vertical board 9 is 1:1.75 - 2.0, preferably 1:1.86 with the best load strength and the largest stirring diameter. In order to prevent the straw from blocking the discharge port 6 during the fermentation process, therefore, a scraping plate 11 coaxially connected to the lower end of the shaft rod 8 is arranged. Thus, through the rotation of the scraping plate 11, the straw is prevented from moving to the position of the discharge port 6. In order to improve the effect of the scraping plate 11, therefore, two bent edges 12 are formed at the edge position of the scraping plate 11. Thus, the straw blocking the discharge port 6 is dug out by means of the bent edges 12. The angle between one bent edge 12 and the vertical direction is 3 - 5°, and the angle between the other bent edge 12 and the vertical direction is 12 - 15°, making the digging effect of the inclined bent edges 12 better.
[0017] During use, the straw is put in through the feeding port 2 of the tank body 3, and the fermentation liquid is added through the liquid inlet. A detachable tank cover can also be added at the position of the feeding port 2. Then, the motor 7 can be started to drive the shaft rod 8 to rotate. The shaft rod 8 drives the paddle boards on its side, and the straw inside the tank body 3 is driven to perform a turning and stirring operation through the sickle-shaped vertical board 9 and the straight plate-shaped horizontal board 10. Thus, the straw and the fermentation liquid are in full contact, which can not only ensure the full fermentation of the straw but also improve the fermentation rate of the straw. The scraping plate 11 at the bottom of the shaft rod 8 can dig out the straw blocking the discharge port 6 to prevent the straw from falling to the position of the discharge port 6 due to natural settlement during the fermentation process. Thus, through the rotation of the scraping plate 11, the straw is forced not to move towards the position of the discharge port 6. If a small amount of straw accidentally enters the discharge port 6, it can also be dug out by means of the inclined bent edges 12 through rotation.
