[0027] The exemplary embodiments of the present application will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0028] The compost bin is used to ferment materials such as kitchen waste and feces to process the materials.

[0029] However, during the fermentation process in the compost bin, fresh materials are added, and different materials have different fermentation times, resulting in the fermented materials and fresh materials being mixed together, making it difficult to separate the fermented materials from the fresh materials, and thus making it difficult to take out the fermented materials.

[0030] To at least solve the problem that it is difficult to separate the fermented materials from the fresh materials. An embodiment of the present application proposes a fermentation chamber 110 that can separate the fermented materials from the fresh materials.

[0031] An embodiment of the present application also proposes a fermentation device 100 including the fermentation chamber 110 of the above embodiment.

[0032] The fermentation chamber 110 and the fermentation device 100 of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0033] Combined Figure 1 and Figure 2 As shown, the fermentation chamber 110 of the embodiment of the present application includes: a chamber body 1, a heating device (not shown in the figure), and a stirring assembly 2. An inlet chamber 12 and an outlet chamber 13 are defined in the chamber body 1. The inlet chamber 12 and the outlet chamber 13 are separated by a partition 11. A connection hole 111 penetrating the partition 11 is provided at the upper end of the partition 11. The inlet chamber 12 and the outlet chamber 13 are both communicated with the connection hole 111. The connection hole 111 is configured to enable the dust in the inlet chamber 12 to enter the outlet chamber 13. The heating device is provided in the chamber body 1 and is configured to heat the materials in the inlet chamber 12 so that the fresh materials in the inlet chamber 12 can be fermented into fermented materials. The stirring assembly 2 includes a stirring shaft 21 and a first stirring paddle 22. The stirring shaft 21 is rotatably provided in the chamber body 1. At least part of the stirring shaft 21 is located in the inlet chamber 12 and is connected to the first stirring paddle 22. The first stirring paddle 22 is configured to stir the fresh materials and the fermented materials, and is also configured to lift the fermented materials to convert the fermented materials into dust.

[0034] Add fresh materials into the inlet chamber 12. Under the heating action of the heating device, the temperature in the inlet chamber 12 is suitable for microbial fermentation, so that the fresh materials in the inlet chamber 12 are fermented. During the fermentation process, microorganisms generate heat energy, which can kill the eggs in the fresh materials. Moreover, during the fermentation process, the water content in the fresh materials decreases, and some adhesives in the fresh materials are gradually decomposed. After the fresh materials are fermented into fermented materials, due to the low water content and adhesive content, the weight of the fermented materials is small, and it is easy to disintegrate into powder.

[0035] The first stirring paddle 22 is driven to rotate by the stirring shaft 21. Under the action of the first stirring paddle 22, part of the fermented material in the feed chamber 12 is lifted. Since the fermented material is in powder form, it is easy for the fermented material to form flying dust. Part of the flying dust enters the discharge chamber 13 through the connection hole 111, and the other part of the flying dust settles in the feed chamber 12 and thus is located at the upper end of the feed chamber 12. When the material in the feed chamber 12 is higher than the bottom end of the connection hole 111, the settled flying dust pours into the discharge chamber 13 through the connection hole 111 and thus enters the discharge chamber 13.

[0036] Since the fermented material is lighter in weight and the fresh material is heavier, under the stirring action of the first stirring paddle 22, the fresh material gradually locates at the lower end of the feed chamber 12, and the fermented material is at the upper end of the feed chamber 12. When the material in the feed chamber 12 is higher than the bottom end of the connection hole 111, the fermented material pours into the discharge chamber 13 through the connection hole 111 and thus enters the discharge chamber 13.

[0037] Thus, the fermented material and the fresh material can be screened and separated, enabling the fermented material to enter the discharge chamber 13 from the feed chamber 12, thereby realizing the separation of the fermented material. The fermented material can be taken out by taking the material through the discharge chamber 13.

[0038] Optionally, the heating device can also heat the material in the discharge chamber 13, thereby promoting the decomposition of the material in the discharge chamber 13.

[0039] It should be noted that there are multiple radial directions c of the stirring shaft. Figure 2 Only one exemplary radial direction c of the stirring shaft is marked therein.

[0040] As Figure 2 shown, in some embodiments, the width direction a of the first stirring paddle intersects with the axial direction b of the stirring shaft, and the width direction a of the first stirring paddle intersects with the radial direction c of the stirring shaft.

[0041] It should be noted that the radial direction c of the stirring shaft is the direction perpendicular to the circumferential direction b of the stirring shaft, and there are multiple directions of the radial direction c of the stirring shaft. The width direction a of the first stirring paddle intersecting with the radial direction c of the stirring shaft means that the width direction a of the first stirring paddle intersects with the radial direction c of each stirring shaft.

[0042] The width direction a of the first stirring paddle intersects with the axial direction b of the stirring shaft, that is to say, the first stirring paddle 22 is inclined relative to the stirring shaft 21, so that during the rotation of the first stirring paddle 22, the material can be moved along the axial direction b of the stirring shaft.

[0043] The width direction a of the first stirring paddle intersects with the radial direction c of the stirring shaft, so that in the rotation direction of the stirring shaft 21, the first stirring paddle 22 has a relatively large contact area, and thus the first stirring paddle 22 has a better stirring effect.

[0044] In this embodiment, by intersecting the width direction a of the first stirring paddle with the axial direction b of the stirring shaft and intersecting the width direction a of the first stirring paddle with the radial direction c of the stirring shaft, the first stirring paddle 22 has a better stirring effect.

[0045] Combined Figure 1 and Figure 2 As shown, in some embodiments, a feed inlet 14 for feeding is provided at the upper end of the bin body 1. The feed inlet 14 communicates with the feed chamber 12. In the axial direction of the stirring shaft 21, the feed inlet 14 is oppositely arranged with the connecting hole 111. A plurality of first stirring paddles 22 are provided, and in the axial direction of the stirring shaft 21, the plurality of first stirring paddles 22 are arranged at intervals.

[0046] By arranging the feed inlet 14 and the connecting hole 111 oppositely, the distance between the feed inlet 14 and the connecting hole 111 can be increased. In the axial direction of the stirring shaft 21, the plurality of first stirring paddles 22 are arranged at intervals. Thus, when the fermentation material moves from the feed inlet 14 to the connecting hole 111, it can contact the plurality of first stirring paddles 22, thereby increasing the probability that the fermentation material is chopped.

[0047] In some embodiments, the plurality of first stirring paddles 22 are 15 first stirring paddles 22, and the angle between every two adjacent first stirring paddles 22 is 120°.

[0048] By making the angle between every two adjacent first stirring paddles 22 be 120°, the angle distribution between the plurality of first stirring paddles 22 can be made uniform, and thus the radial force on the stirring shaft 21 is made uniform.

[0049] In some embodiments, the plurality of first stirring paddles 22 are 16 first stirring paddles 22, and the angle between every two adjacent first stirring paddles 22 is 90°.

[0050] By making the angle between every two adjacent first stirring paddles 22 be 90°, the angle distribution between the plurality of first stirring paddles 22 can be made uniform, and thus the radial force on the stirring shaft 21 is made uniform.

[0051] As Figure 1 shown, in some embodiments, the stirring assembly 2 further includes a second stirring paddle 23 located in the discharge chamber 13 and a drive motor 25 located outside the bin body 1. At least another part of the stirring shaft 21 is located in the discharge chamber 13 and is connected to the second stirring paddle 23, and the drive motor 25 is in transmission connection with the stirring shaft 21.

[0052] The fermentation materials in the discharge chamber 13 can be stirred by the second stirring paddle 23, facilitating the decomposition of the fermentation materials.

[0053] Combined with Figure 4 As shown, in some embodiments, both the first stirring paddle 22 and the second stirring paddle 23 include a stirring portion 221 and a connecting portion 222. The axial direction and the radial direction of the stirring shaft 21 intersect with the width direction of the stirring portion 221. The connecting portion 222 is connected to the stirring shaft 21 and defines a socket groove (not shown in the figure). The stirring portion 221 is inserted into the socket groove. In the thickness direction of the stirring portion 221, part of the connecting portion 222 is located on one side of the stirring portion 221, and part of the connecting portion 222 is located on the other side of the stirring portion 221.

[0054] The stirring portion 221 can be installed through the connecting portion 222, enabling the structures of the first stirring paddle 22 and the second stirring paddle 23 to be simple and stable.

[0055] By having part of the connecting portion 222 on one side of the stirring portion 221 and part of the connecting portion 222 on the other side of the stirring portion 221, during the rotation of the first stirring paddle 22, the fermentation materials can be chopped by the connecting portion 222, thus increasing the ability of the first stirring paddle 22 to chop the fermentation materials. In addition, the ability of the second stirring paddle 23 to chop the fermentation materials can also be increased, facilitating the further decomposition of the fermentation materials in the discharge chamber 13.

[0056] Combined with Figure 2 and Figure 3 As shown, in some embodiments, the stirring portion 221 is provided with a connecting groove 2211, and an outer ring of the stirring shaft 21 is provided with a connecting ring 24. The connecting ring 24 passes through the connecting groove 2211, and the connecting portion 222 abuts against the connecting ring 24 and is connected by a threaded member.

[0057] The stirring portion 221 can be positioned through the connecting ring 24 and the connecting groove 2211, thereby increasing the stability of the stirring portion 221.

[0058] The ability of the first stirring paddle 22 to chop the fermentation materials can be further increased through the connecting ring 24. In addition, the ability of the second stirring paddle 23 to chop the fermentation materials can also be further increased, facilitating the further decomposition of the fermentation materials in the discharge chamber 13.

[0059] Specifically, the connecting ring 24 is a coupling, facilitating the installation of the first stirring paddle 22 and the second stirring paddle 23.

[0060] Such as Figure 3As shown, in some embodiments, the stirring part 221 includes a first stirring section 2212 and a second stirring section 2213. One end of the first stirring section 2212 is provided with a connecting groove 2211. The other end of the first stirring section 2212 is connected to the second stirring section 2213. The width of the first stirring part 221 decreases in the direction close to the second stirring part 221, and the width of part of the second stirring part 221 is greater than or equal to the width of the first stirring part 221.

[0061] By making the width of the first stirring part 221 decrease in the direction close to the second stirring part 221, the resistance received by the second stirring part 221 during stirring can be appropriately reduced. By making the width of part of the second stirring part 221 greater than or equal to the width of the first stirring part 221, the contact area between the second stirring part 221 and the material can be increased, and thus the stirring effect of the second stirring part 221 can be increased.

[0062] In other embodiments, the stirring assembly 2 further includes a connecting shaft and a second stirring paddle 23 located in the discharge chamber 13, and a first driving motor and a second driving motor located outside the bin body 1. The connecting shaft is connected to the second stirring paddle 23, and the second driving motor is in transmission connection with the connecting shaft. The first driving motor is in transmission connection with the stirring shaft 21.

[0063] The second stirring paddle 23 can stir the fermented material in the discharge chamber 13, so as to facilitate the ripening of the fermented material.

[0064] In addition, by connecting the connecting shaft to the second stirring paddle 23 and the second driving motor to the connecting shaft in transmission connection. The first driving motor is in transmission connection with the stirring shaft 21. The rotation speeds of the first stirring paddle 22 and the second stirring paddle 23 can also be adjusted respectively, so that the rotation speeds of the first stirring paddle 22 and the second stirring paddle 23 can better meet the production requirements.

[0065] As Figure 1 shown, in some embodiments, at least part of the connecting holes 111 are lower than the feed inlet 14.

[0066] When the height of the material in the feed chamber 12 is higher than the connecting holes 111, the material will have an overflow effect, and the material will enter the discharge chamber 13 through the connecting holes 111, so that the material can be lower than the feed inlet 14, so as to avoid overloading of the driving motor 25 caused by too much material in the feed chamber 12.

[0067] As Figure 1 shown, in some embodiments, the lower end of the bin body 1 is provided with a discharge port 15, and the discharge port 15 is communicated with the discharge chamber 13.

[0068] By providing the discharge port 15, it is convenient to discharge the material in the discharge chamber 13.

[0069] In some embodiments, the volume ratio or length ratio of the feed chamber 12 to the discharge chamber 13 is 4:1, so that the sizes of the feed chamber 12 and the discharge chamber 13 can be adapted to each other.

[0070] In some embodiments, the quantity ratio of the first stirring paddle 22 to the second stirring paddle 23 is 3 - 6:1, so that the axial force on the stirring shaft 21 can be evenly distributed.

[0071] As Figure 4 shown, the fermentation device 100 of the embodiment of the present application includes a housing 120 and the fermentation chamber 110 of the above embodiment, and the fermentation chamber 110 is arranged inside the housing 120.

[0072] When the fermentation device 100 of the embodiment of the present application is operating, under the heating action of the heating device, the temperature in the feed chamber 12 is suitable for microbial fermentation, so that the fresh materials in the feed chamber 12 are fermented. During the fermentation process, the microorganisms generate heat energy, which can kill the insect eggs in the fresh materials. Moreover, during the fermentation process, the water content in the fresh materials decreases, and some of the adhesives in the fresh materials are gradually decomposed. After the fresh materials are fermented into fermented materials, due to the low water content and adhesive content, the weight of the fermented materials is small and they are easy to disintegrate.

[0073] The first stirring paddle 22 is driven to rotate by the stirring shaft 21. Under the action of the first stirring paddle 22, some of the fermented materials in the feed chamber 12 are lifted up. Since the fermented materials are in powder form, they are easy to form flying dust. Some of the flying dust enters the discharge chamber 13 through the connecting hole 111, and the other part of the flying dust settles in the feed chamber 12 and is thus located at the upper end of the feed chamber 12. When the materials in the feed chamber 12 are higher than the bottom end of the connecting hole 111, the settled flying dust pours into the discharge chamber 13 through the connecting hole 111 and thus enters the discharge chamber 13.

[0074] Since the fermented materials are lighter in weight and the fresh materials are heavier, under the stirring action of the first stirring paddle 22, the fresh materials gradually move to the lower end of the feed chamber 12, and the fermented materials are located at the upper end of the feed chamber 12. When the materials in the feed chamber 12 are higher than the bottom end of the connecting hole 111, the fermented materials pour into the discharge chamber 13 through the connecting hole 111 and thus enter the discharge chamber 13.

[0075] Thus, the fermented materials and the fresh materials can be screened and separated, so that the fermented materials enter the discharge chamber 13 from the feed chamber 12, thereby realizing the separation of the fermented materials. The fermented materials can be taken out through the discharge chamber 13.

[0076] By arranging the fermentation chamber 110 inside the housing 120, it is possible to prevent water from entering the fermentation chamber 110, thereby increasing the fermentation effect of the fermentation chamber 110.
