[0055] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the description and drawings are essentially for illustrative purposes and are not intended to limit the present invention.

[0056] In the following description of various exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form a part hereof and illustrate, by way of example, various exemplary structures, systems, and steps that may implement various aspects of the present invention. It should be understood that other specific embodiments of components, structures, exemplary devices, systems, and steps may be used, and that structural and functional modifications may be made without departing from the scope of the present invention.

Nothing in this specification should be construed as requiring a specific three-dimensional orientation of a structure to fall within the scope of the present invention.

[0057] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the anaerobic fermentation reaction box 2 of the present invention includes at least one concrete module 10, at least one metal structure module 11, and a metal frame 12. The concrete module 10 includes two walls 102 and a top wall 101. The top wall 101 is supported between the two walls 102 and, together with the two walls 102, forms a first space. The metal structure module 11 includes two wall panels 112 and a top plate 111. The two wall panels 112 support the top plate 111 to form a second space. The wall panels 112 are sealed to the walls 102, and the top plate 111 is sealed to the top wall 101. The second space is connected to the first space to form a reaction space. The metal frame 12 is disposed on the side of the concrete module 10 away from the first space.

[0058] The anaerobic fermentation reaction box 2 of the present invention is composed of a concrete module 10 and a metal structure module 11 to form a reaction space in the box, which can meet the strength of the box and reduce the weight of the box. A metal frame 12 is set on the side of the concrete module 10 away from the reaction space, which can enhance the strength and stability of the concrete module 10 and avoid the occurrence of problems such as deformation of the concrete module 10 caused by the movement of the stirring structure 14 set on the concrete module 10. When it is necessary to expand the reaction space in the box, it can be achieved by directly adding concrete modules 10 or metal structure modules 11, which reduces the cost of the box and the installation period, improves production efficiency, and can be modularly expanded according to production capacity. Among them, the material of the metal structure module 11 can be stainless steel, carbon steel, etc.

[0059] In this embodiment, the anaerobic fermentation reaction chamber 2 further includes an end plate 13. This end plate 13 is connected to the concrete module 10 or the metal structure module 11, enclosing the reaction space. The end plate 13 can be made of metal or other materials. It is also preferable to use a corrosion-resistant material. If a non-corrosion-resistant material is used, the end plate 13 will need to be frequently replaced during use.

[0060] In this embodiment, the metal frame 12 includes a first wall frame 121, which is disposed on a side of one of the walls 102 of the concrete module 10 that is away from the first space. Providing the first wall frame 121 on the wall 102 of the concrete module 10 can enhance the strength of the wall 102 of the concrete module 10.

[0061] In this embodiment, the metal frame 12 further includes a second wall frame 122, which is disposed on a side of the other wall 102 of the concrete module 10 that is away from the first space. Providing the second wall frame 122 on the wall 102 of the concrete module 10 can further strengthen the wall 102 of the concrete module 10.

[0062] In this embodiment, the metal frame 12 further includes a top frame 123, which is disposed on the top wall 101 of the concrete module 10 and connects the first wall frame 121 and the second wall frame 122. The top frame 123 connects the first wall frame 121 and the second wall frame 122 to form the metal frame 12 surrounding the concrete module 10, thereby increasing the overall strength of the concrete module 10 and minimizing deformation of the concrete module 10.

[0063] The metal frame 12 of the present application can adopt a truss structure or other hollow frame structure, which can reduce material and lower costs. The top frame 123 can be composed of multiple hollow rectangular structures connected together, or it can be formed from multiple hollow rectangular structures in one piece. The first wall frame 121 includes two parts, both of which are composed of multiple hollow rectangular structures and are arranged relative to each other, avoiding the mixing structure 14 installed on the concrete module 10 while providing a certain degree of support. The shape and structure of the second wall frame 122 are the same as the first wall frame 121.

[0064] In this embodiment, if Figures 3 and 4 As shown, the thickness of the wall 102 of the concrete module 10 is greater than the thickness of the wallboard 112 of the metal structure module 11. This ensures the strength of the entire anaerobic fermentation reaction box 2 and the stability of the mixing structure 14 provided in the concrete module 10, thereby avoiding dimensional changes caused by temperature changes during the mixing process.

[0065] In this embodiment, the thickness of the top wall 101 of the concrete module 10 is greater than the thickness of the top plate 111 of the metal structure module 11. This ensures the strength of the entire anaerobic fermentation reaction box 2 and the stability of the mixing structure 14 provided in the concrete module 10, thereby preventing dimensional changes caused by temperature changes during the mixing process.

[0066] In this embodiment, the wall 102 or top wall 101 of the concrete module 10 is provided with a groove, with a metal plate 200 disposed at the bottom of the groove. The wall panel 112 or top panel 111 of the metal structural module 11 is inserted into the groove and sealed to the metal plate 200. The embedded metal plate 200 in the groove achieves a sealed connection between the concrete module 10 and the metal structural module 11, resulting in a simple structure, good sealing performance, and a simple manufacturing process at a low cost. The metal plate 200 can be made of the same material as the metal structural module 11.

[0067] In this embodiment, the wall panels 112 or the top panels 111 of the metal structure modules 11 are welded to the metal plates 200. By welding the metal structure modules 11 and the concrete modules 10 together through the embedded metal plates 200, a sealing effect can be effectively ensured. Compared with welding of a large area of ​​the metal structure modules 11, the construction period is greatly shortened, which helps to improve assembly efficiency.

[0068] There is a small gap (not shown in the figure) between the wall plate 112 or the top plate 111 of the metal structure module 11 inserted into the groove and the groove, where welding rods can be placed to complete welding.

[0069] In other embodiments, bolts can be embedded in the grooves of the concrete modules 10, and then the metal structural modules 11 can be inserted into the bolts in the grooves for a sealed fixation. In this embodiment, both embedded bolts 100 and metal plates 200 are used for fixation. If metal plates 200 are used alone, they can cover the entire bottom of the groove or be placed on a portion of the bottom.

[0070] like Figure 8 As shown, bolts 100 are embedded in the concrete module 10, and the metal frame 12 is connected to the concrete module 10 via the bolts 100. Using embedded bolts 100 to connect the metal frame 12 and the concrete module 10 ensures that the metal frame 12 supports the concrete module 10. Furthermore, the connection method is simple and effective, and the operation is simple, making it easy to replace the metal frame 12 as needed.

[0071] See also Figures 1 to 7 The present invention further provides an anaerobic fermentation reaction device 1 , comprising a stirring structure 14 and the above anaerobic fermentation reaction box 2 , wherein the stirring structure 14 is disposed on the concrete module 10 .

[0072] In this embodiment, the stirring structure 14 includes a driving assembly 141, a stirring shaft 142, a stirring blade 143 and a driven assembly 144. The stirring shaft 142 connects the driving assembly 141 and the driven assembly 144. The stirring blade 143 is arranged on the stirring shaft 142. The driving assembly 141 and the driven assembly 144 are respectively arranged on the two walls 102. The stirring shaft 142 and the stirring blade 143 are arranged in the reaction space.

[0073] The drive assembly 141 is located between the two sections of the first wall frame 121 of the metal frame 12, and the driven assembly 144 is located between the two sections of the second wall frame 122 of the metal frame 12. The drive assembly 141 includes a motor and a reducer 1411, and a drive bracket 1412. It may also include a coupling, a stirring shaft support, and other components. The driven assembly 144 includes a driven support 1441, a driven bracket 1442, and other components.

[0074] The above is a detailed description of several exemplary embodiments of the anaerobic fermentation reaction box 2 and the anaerobic fermentation reaction device 1 proposed in the present invention. The following is an exemplary description of the installation process of the anaerobic fermentation reaction box 2 and the anaerobic fermentation reaction device 1 proposed in the present invention.

[0075] Combined with attachment Figures 1 to 8 The installation process of the anaerobic fermentation reaction box 2 and the device 1 proposed by the present invention is:

[0076] First, the mixing structure 14 is installed on the concrete module 10 , the driving assembly 141 and the driven assembly 144 are respectively installed on the two walls 102 , and the mixing shaft 142 and the mixing blades 143 are installed in the reaction space.

[0077] Then, the wall panels 112 and the top panels 111 of the metal structure module 11 are aligned with the grooves of the wall 102 and the top panel 101 of the concrete module 10 , and the metal structure module 11 is welded to the pre-embedded metal plate 200 of the concrete module 10 .

[0078] According to actual production needs, the number of concrete modules 10 and metal structure modules 11 to be spliced ​​is selected and the splicing is completed in the above manner. After completion, each concrete module 10 is connected to a metal structure module 11 on both sides.

[0079] Afterwards, the metal frame 12 is fixed to the top wall 101 and the wall 102 of the concrete module 10 through the embedded bolts 100 on the concrete module 10 , and the first wall frame 121 and the second wall frame 122 of the wall 102 of the metal frame 12 avoid the mixing structure 14 .

[0080] Finally, the end plate 13 is fixed to the metal structure module 11 .

[0081] Through the installation process of the anaerobic fermentation reaction box 2 and the device of the utility model described above, it can be concluded that the anaerobic fermentation reaction box 2 of the utility model is composed of a concrete module 10 and a metal structure module 11 to form a reaction space in the box, which can meet the strength of the box and reduce the weight of the box. A metal frame 12 is provided on the side of the concrete module 10 away from the reaction space, which can enhance the strength and stability of the concrete module 10 and avoid the occurrence of problems such as deformation of the concrete module 10 caused by the movement of the stirring structure 14 provided on the concrete module 10. When it is necessary to expand the reaction space in the box, it can be achieved by directly adding concrete modules 10 or metal structure modules 11, thereby reducing the cost of the box and the installation period, improving production efficiency, and the box can be modularly expanded according to production capacity.

[0082] In summary, the anaerobic fermentation reaction chamber proposed in the present invention comprises at least one concrete module, at least one metal structural module, and a metal frame. The concrete module comprises two walls and a top wall, the top wall being supported between the two walls and enclosing a first space with the two walls. The metal structural module comprises two wall panels and a top panel, the two wall panels supporting the top panel enclosing a second space. The wall panels are sealed to the walls, and the top panel is sealed to the top walls. The second space is connected to the first space to form a reaction space. The metal frame is disposed on the side of the concrete module facing away from the first space. The combination of concrete modules and metal structural modules forms the reaction space within the chamber, ensuring both the strength and weight of the chamber. If the reaction space within the chamber needs to be expanded, this can be achieved by directly adding concrete modules or metal structural modules, reducing the chamber's construction cost and installation cycle, improving production efficiency, and allowing the chamber to be modularly expanded according to production capacity. The metal frame disposed on the side of the concrete module facing away from the reaction space enhances the strength and stability of the concrete module, preventing deformation of the concrete module caused by movement of the mixing structure provided on the concrete module.

[0083] The anaerobic fermentation reaction device proposed in this utility model comprises the above-mentioned anaerobic fermentation reaction chamber and a mixing structure disposed within a concrete module. This ensures the stability of the mixing structure disposed within the concrete module, preventing dimensional changes caused by temperature fluctuations during the mixing process. The mixing structure is disposed within the concrete module rather than the metal structure module, which allows the metal structure module to be designed with only compressive strength considerations in mind, without having to account for the effects of other complex deformations. This simplifies design considerations and improves design efficiency.
