[0050] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, the anaerobic fermentation reaction box 2 of the utility model includes at least one concrete module 10 and at least two metal structure modules 11. 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 forms a first space with the two walls 102. 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 and connected to the walls 102, the top plate 111 is sealed and connected to the top wall 101, and the second space is connected to the first space to form a reaction space.

[0051] The anaerobic fermentation reaction box 2 of the utility model is composed of a concrete module 10 and a metal structure module 11, which avoids the problem of insufficient lightness of a completely steel structure box and solves the problem of heavy weight of a completely concrete structure, meets the strength of the box and reduces the weight of the box. When the reaction space in the box needs to be expanded, it can be achieved by directly adding a concrete module 10 or a metal structure module 11, which reduces the cost of the box and the installation cycle, improves production efficiency, and can be modularly expanded according to production capacity.

[0052] In this embodiment, the material of the metal structure module 11 can be a steel structure module such as stainless steel, carbon steel, etc. The metal structure module 11 is a steel structure module, which is corrosion-resistant, improves the structural strength of the entire box and reduces the outer contour size of the box.

[0053] In this embodiment, the anaerobic fermentation reaction box 2 further includes an end plate 13. The end plate 13 is connected to the concrete module 10 or the metal structure module 11 to close the reaction space. The end plate 13 can be made of metal material or other materials. In addition, the end plate 13 is preferably made of corrosion-resistant material. If a non-corrosion-resistant material is used, it needs to be replaced frequently during use.

[0054] In this embodiment, if Figure 3 to Figure 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. In this way, the strength of the entire anaerobic fermentation reaction box 2 can be ensured, and the stability of the stirring structure 14 set in the concrete module 10 can be ensured, avoiding the size change caused by temperature change during the stirring process.

[0055] 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. In this way, the strength of the entire anaerobic fermentation reaction box 2 can be ensured, and the stability of the stirring structure 14 provided in the concrete module 10 can be ensured, and the dimensional change caused by temperature change during the stirring process can be avoided.

[0056] In this embodiment, the wall 102 or the top wall 101 of the concrete module 10 is provided with a groove, the bottom of the groove is provided with a metal plate 200, and the wall plate 112 or the top plate 111 of the metal structure module 11 is inserted into the groove and sealed to the metal plate 200.

The material of the metal plate 200 can be the same as that of the metal structure module 11.

[0057] In this embodiment, the wall plate 112 or the top plate 111 of the metal structure module 11 is welded to the metal plate 200. By welding the metal structure module 11 and the concrete module 10 together through the embedded metal plate 200, the sealing effect can be effectively ensured, and compared with the welding of a large range of metal structure modules 11, the construction period is greatly shortened, which is conducive to improving assembly efficiency.

[0058] 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.

[0059] In some other embodiments, embedded bolts 100 may be provided in the groove of the concrete module 10, and then the metal structure module 11 may be inserted into the embedded bolts 100 in the groove for sealing and fixing. It is also possible to use both embedded bolts 100 and metal plates 200 for fixing. In this embodiment, both embedded bolts 100 and metal plates 200 are used for fixing. If the metal plate 200 is used alone, the metal plate 200 may cover the entire bottom of the groove, or may be provided on a portion of the bottom of the groove.

[0060] In some other embodiments, the wall 102 or the top wall 101 of the concrete module 10 is provided with a groove, and a metal groove is provided in the groove, and the metal groove is fixedly attached to the concrete module 10 (see Figure 4 In this embodiment, it is possible to use Figure 4The two sides of the metal plate 200 in the concrete module extend outward along the surface of the concrete module to form a U-shaped metal groove), a viscous sealant is provided in the metal groove, the wall plate 112 or the top plate 111 of the metal structure module 11 is inserted into the metal groove, and the viscous sealant is squeezed to achieve a sealed connection. In this case, there is no gap between the wall plate 112 or the top plate 111 of the metal structure module 11 inserted into the metal groove and the metal groove, similar to a gap for placing solder.

[0061] See also Figures 1 to 7 The utility model 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 arranged on the concrete module 10 .

[0062] 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.
