DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to solve the problem that the existing stirring method has a small stirring range, some materials may not be effectively stirred, resulting in a reduction in the contact area between microorganisms and organic matter, thereby affecting the metabolic activity of microorganisms and reducing fermentation efficiency, the following preferred technical solutions are provided:

[0022] A biogas fermentation device with a stirring function includes a fermentation tank 1, a stirring mechanism 2 is installed in the cavity of the fermentation tank 1, and the stirring mechanism 2 includes a motor 21 arranged on the outer wall of the fermentation tank 1, the output end of the motor 21 passes through the outer wall of the fermentation tank 1, and the output end of the motor 21 is fixedly connected to a rotating rod 22, the outer wall of the rotating rod 22 is fixedly connected to a stirring paddle 23, a reciprocating component 24 is installed at the end of the rotating rod 22 away from the motor 21, and an upper push component 25 is installed at the upper end of the reciprocating component 24. The rotating rod 22 is driven to rotate by the motor 21, and the rotation of the rotating rod 22 can drive the reciprocating component 24 to reciprocate and push the upper push component 25. The reciprocating component 24 includes a screw thread connected to the outer wall of the rotating rod 22. A driving gear 241 is fixedly connected, and a first gear rod 242 and a second gear rod 243 are respectively provided on both sides of the driving gear 241. The first gear rod 242 and the second gear rod 243 are symmetrically distributed about the center of the driving gear 241. The upper ends of the first gear rod 242 and the second gear rod 243 are jointly fixedly connected with a top block body 244. The driving gear 241 is only provided with meshing teeth on half of its outer wall, and the driving gear 241 is meshed and connected with the first gear rod 242 and the second gear rod 243. When the driving gear 241 is connected to the first gear rod 242, the top block body 244 tends to move upward. When the driving gear 241 is connected to the second gear rod 243, the top block body 244 tends to move downward.

[0023] The upper top assembly 25 includes a receiving block 251, one end of which is fixedly connected to the top block body 244. The upper end of the receiving block 251 is fixedly connected to the upper top block 252. The upper top block 252 is a component made of beryllium bronze, and the interior of the upper top block 252 is a hollow structure. The outer walls on both sides of the receiving block 251 are respectively provided with a first material guide groove 253 and a second material guide groove 254, and multiple groups of the first material guide groove 253 and the second material guide groove 254 are provided.

[0024] Specifically, the fermentation tank 1 can convert organic matter into biogas and organic fertilizer through the metabolism of microorganisms. When stirring the material in the fermentation tank 1, the motor 21 is first started, and the motor 21 is used to drive the rotating rod 22 to rotate. The stirring paddle 23 can stir the material through the rotating rod 22.

When the driving gear 241 is connected to the second gear rod 243, the top block body 244 is driven to move downward, thereby driving the top block body 244 to reciprocate and push the upper push component 25, so that the upper push component 25 continuously pushes the material, thereby improving the stirring efficiency, solving the problem that the existing stirring method has a small stirring range and some materials may not be effectively stirred, resulting in a reduced contact area between microorganisms and organic matter, thereby affecting the metabolic activity of microorganisms and reducing the fermentation efficiency.

[0025] When the upper push assembly 25 continuously pushes the material, since the upper push block 252 is made of beryllium bronze and the interior of the upper push block 252 is a hollow structure, the upper wall of the upper push block 252 will be concave inward when pushing up. When moving down, the upper push block 252 will be able to reset instantly due to its own elasticity, and can push the material again at the moment of reset, further improving the stirring efficiency.
