Accordingly, such terms as used herein should not be construed as limiting the scope of the present application.

[0039] Furthermore, the features described in the different embodiments of the application described below can be combined with each other, unless explicitly stated otherwise.

[0040] As Figures 1 to 5As shown, the disc fermentation device provided in this application embodiment includes a disc 10, a bridge frame 20, and a drive device 30. The disc 10 includes a support portion 11 for carrying the material to be fermented. The bridge frame 20 is disposed above the support portion 11. The drive device 30 is configured to drive the disc 10 and the bridge frame 20 to rotate relative to each other around the central axis of the disc 10. The drive device 30 includes a drive wheel 31 and a gear ring 32 that mesh with each other, and a drive mechanism 33 that is drivenly connected to the drive wheel 31. The gear ring 32 is coaxially mounted on the disc 10. The gear ring 32 includes at least two layers 321 stacked along the axial direction of the gear ring 32. Each layer 321 includes at least two arc segments 3211 spliced ​​along the circumference of the gear ring 32. The splice seams 321A of adjacent arc segments 3211 of adjacent layers 321 are staggered along the circumference of the gear ring 32.

[0041] The drive device 30 is configured to drive the disk 10 and the bridge 20 to rotate relative to each other around the central axis of the disk 10. Alternatively, the disk 10 can be fixed and the bridge 20 can rotate around the central axis of the disk 10, or the bridge 20 can be fixed and the disk 10 can rotate around its own central axis.

[0042] In this embodiment of the disc fermentation equipment, the structure of the toothed ring 32 allows for the manufacture of only the arc segments 3211. During the installation of the toothed ring 32, the arc segments 3211 of each layer 321 can be assembled onto the disc 10 according to the staggered requirements. In the production, transportation, installation, and maintenance stages, multiple smaller arc segments replace the complete large toothed ring. By controlling the precision of each arc segment, the precision of the toothed ring can be controlled, which helps to reduce the cost and difficulty of each processing, assembly, and maintenance while ensuring the precision of the toothed ring.

[0043] like Figures 1 to 5 As shown, in some embodiments of the disc fermentation apparatus, the disc 10 further includes a baffle portion 12 disposed on the outer periphery of the support portion 11, a toothed ring 32 is installed on the top of the baffle portion 12, and the bridge frame 20 is supported on the top surface of the toothed ring 32.

[0044] The gear ring 32 is installed at the top of the enclosure 12, and the cable tray 20 is supported on the top surface of the gear ring 32, which facilitates the relative rotation of the cable tray 20 and the disc 10, thereby achieving stable support for the cable tray 20.

[0045] like Figures 1 to 5 As shown, in some embodiments of the disc fermentation apparatus, the disc 10 further includes a plurality of mounting seats 13 arranged at intervals along the circumference of the disc 10 at the top of the enclosure portion 12, and the toothed ring 32 is mounted on the mounting seats 13. Figure 1 and Figure 2 As shown, the mounting base 13 can be, for example, cylindrical, such as... Figure 3 and Figure 4 As shown, the mounting base 13 can also be plate-shaped.

[0046] By setting the mounting seat 13, it is beneficial for the stable installation of the ring gear 32 and the disc 10, and also beneficial for the ring gear 32 to achieve higher positioning accuracy, for example, to ensure the horizontal of the top surface of the ring gear 32, thereby facilitating the smooth movement of the bridge 20 relative to the disc 10.

[0047] As shown in the drawings, in some embodiments of the disc fermentation equipment, the disc fermentation equipment further comprises a center column 40 coaxially arranged with the disc 10, wherein the bridge 20 is rotatably mounted on the center column 40, and the disc 10 is fixed to the center column 40. Figures 1 to 5

[0048] In some embodiments not shown in the drawings, the disc 10 is rotatably mounted on the center column 40, and the bridge 20 is fixed to the center column 40.

[0049] By setting the center column 40, it is beneficial for the center of rotation of the parts in the disc 10 and the bridge 20 relative to the center column 40 to be stable.

[0050] As shown in the drawings, Figures 1 to 3 , Figure 5 In some embodiments of the disc fermentation equipment, the driving mechanism 33 and the driving wheel 31 are mounted on the bridge 20.

[0051] By mounting the driving mechanism 33 and the driving wheel 31 on the bridge 20, it is beneficial for the overall structure of the disc fermentation device to be compact, and the relative movement between the bridge 20 and the disc 10 to be smooth. As shown in the drawings, Figures 1 to 3 , Figure 5 In some embodiments of the disc fermentation equipment, the bridge 20 comprises a driving beam 21 and a rotating trolley 22. The driving beam 21 extends in the radial direction of the disc 10. The rotating trolley 22 is movably carried on the ring gear 32 in the circumferential direction of the ring gear 32, and the radial outer end of the driving beam 21 is connected with the rotating trolley 22. The driving mechanism 33 and the driving wheel 31 are mounted on the rotating trolley 22.

[0052] By setting the driving beam 21 and the rotating trolley 22, it is beneficial for the driving beam 21 to move smoothly and stably relative to the disc 10.

[0053] As shown in the drawings, Figure 1 and Figure 2 In some embodiments of the disc fermentation equipment, the bridge 20 further comprises a following beam 23 and a supporting wheel 24. The following beam 23 extends in the radial direction of the disc 10 and has an included angle with the driving beam 21. The following beam 23 is fixedly connected with the driving beam 21. The supporting wheel 24 is mounted on the following beam 23 and carried on the ring gear 32.

[0054] By setting the following beam 23 and the supporting wheel 24, it is beneficial for the matching equipment of the disc 10 such as the stirring device, the conveyor and the like to be flexibly arranged as needed, and also beneficial for the bridge 20 to move smoothly relative to the disc 10. ​​​

[0055] In some embodiments of the disc fermentation device, the driving wheel 31 is a gear wheel or a pin wheel; and / or the gear ring 32 is an inner gear ring or an outer gear ring. As shown in the embodiments of Figure 1 and Figure 2 , the driving wheel 31 is a gear wheel and the gear ring 32 is an outer gear ring. As shown in the embodiments of Figures 3 to 5 , the driving wheel 31 is a pin wheel and the gear ring 32 is an inner gear ring.

[0056] The structure of the driving wheel 31 and the gear ring 32 can be flexibly selected according to the structure and arrangement requirements of the disc 10, the bridge 20, the driving device 30 and the supporting equipment, so that the driving wheel 31 and the gear ring 32 are more suitable for the related requirements of the disc fermentation device.

[0057] As shown in the embodiments of Figures 1 to 5 , in some embodiments of the disc fermentation device, the arc segments 3211 of each ring layer 321 of the gear ring 32 are detachably connected.

[0058] The arc segments 3211 of each ring layer 321 of the gear ring 32 are detachably connected, which is beneficial to reduce the cost and difficulty of assembly and maintenance of the gear ring 32. For example, when assembling the gear ring 32, the high-difficulty work of hoisting the large gear ring 32 is changed to the installation of multiple relatively small arc segments 3211, and the installation cost and difficulty are reduced. For another example, when the transmission teeth of an individual arc segment 3211 are worn, only the arc segment 3211 that does not meet the transmission requirements needs to be replaced, and the maintenance cost and difficulty are reduced.

[0059] As shown in the embodiments of Figures 1 to 5 , in some embodiments of the disc fermentation device, the arc segments 3211 of each ring layer 321 of the gear ring 32 are connected by the threaded connecting pieces 322 and / or positioned by the pins 323.

[0060] The gear ring 32 is assembled by the threaded connecting pieces 322, so that the arc segments 3211 are easy to disassemble, and the connecting piece cost and assembly difficulty are low. The use of the pins 323 for positioning is beneficial to the dimensional accuracy of the assembled gear ring 32 meeting the requirements.

[0061] As shown in the embodiments of Figure 1 , Figure 3 and Figure 5 , in some embodiments of the disc fermentation device, the gear ring 32 and the top end of the disc 10 are connected by at least part of the threaded connecting pieces.

[0062] Connecting the gear ring 32 and the top end of the disc 10 by at least part of the threaded connecting pieces can realize the connection of the gear ring 32 and the disc 10 at the same time of assembling the gear ring 32, which is beneficial to reduce the assembly links and improve the installation efficiency.

[0063] The embodiments of the present application will be described in more detail below in combination with Figures 1 to 5 .

[0064] Figures 1 to 2 A disc fermentation device is shown to illustrate some embodiments of the present application. In the present embodiment, the disc fermentation device comprises a disc 10, a bridge 20, a driving device 30 and a central column 40. The central column 40 is coaxially arranged with the disc 10, and the disc 10 is fixed to the central column 40. The bridge 20 is rotatably mounted on the central column 40.

[0065] The disc 10 comprises a bearing part 11 for bearing the material to be fermented, a surrounding part 12 arranged at the outer periphery of the bearing part 11, and a plurality of mounting seats 13 evenly distributed at the top end of the surrounding part 12 in the circumferential direction.

[0066] The driving device 30 is configured to drive the bridge 20 to rotate around the central axis of the disc 10. The driving device 30 comprises a driving wheel 31, a gear ring 32, a driving mechanism 33 and a bearing device 34.

[0067] The driving wheel 31 is a gear wheel, and the gear wheel and the gear ring 32 are in meshing engagement. The transmission teeth of the gear wheel and the gear ring 32 are involute transmission teeth. The driving mechanism 33 is in driving connection with the gear wheel.

[0068] The driving mechanism 33 comprises a driving motor 331 and a speed reducer 332 in driving connection with the driving motor 331. The gear wheel is in driving connection with the speed reducer 332. As shown, the wheel shaft of the gear wheel is coaxially connected with the output shaft of the speed reducer 332. The output shaft of the speed reducer 332 is mounted in the bearing device 34 and is supported by the bearing device 34, so as to improve the stability of the meshing engagement between the gear wheel and the gear ring 32. Figure 1

[0069] The gear ring 32 is coaxially mounted on the plurality of mounting seats 13 of the disc 10, and the mounting seats 13 are columnar. The surrounding part 12 may, for example, be made of concrete, and in this case, the bottom end of the columnar mounting seat 13 may, for example, be mounted at the top end of the surrounding part 12 by a pre-buried manner. The top end of the columnar mounting seat 13 is provided with a threaded hole. The threaded hole is used to cooperate with a screw for connecting the corresponding arc segment 3211 of the gear ring 32 and the mounting seat 13.

[0070] ​The ring gear 32 is an outer ring gear and forms a multi-layer segmented structure. The ring gear 32 includes at least two ring layers 321 stacked along the axial direction of the ring gear 32. The number of ring layers 321 can be two, three, four or more. In the embodiment, the ring gear 32 includes three ring layers 321. Each ring layer 321 includes at least two arc segments 3211 spliced along the circumferential direction of the ring gear 32. The number of arc segments 3211 of each ring layer 321 is two, three, four or more. In the embodiment, each ring layer 321 includes 20 arc segments 3211. The splicing seams 321A of adjacent arc segments 3211 of adjacent ring layers 321 are arranged staggered along the circumferential direction of the ring gear 32. The arc segments 3211 of each ring layer 321 of the ring gear 32 are detachably connected by screws as threaded connections 322 and are positioned to each other by pins 323. The ring gear 32 is fixedly connected to the top end of each mounting seat 13 of the disc 10 by the partial screws of each arc segment 3211.

[0071] In the embodiment, the arc segments 3211 can be manufactured by laser cutting or wire cutting machining process respectively. Laser machining can be done within 0.1-0.5 mm, and fast wire cutting can be done within 0.05-0.08 mm. For a large ring gear of a commonly used disc fermentation device with a diameter of several meters to tens of meters, the ring gear 32 assembled by arc segments 3211 machined by laser machining or wire cutting machining process can meet the precision requirements of the disc fermentation equipment. The ring gear 32 has great advantages in cost and efficiency in later maintenance, updating, repositioning and the like.

[0072] Each arc segment 3211 is provided with uniformly distributed transmission teeth and a set of uniformly distributed positioning pin holes and bolt holes. The arc segments 3211 of each ring layer 321 of the ring gear 32 can be set to a uniform specification to adapt to batch manufacturing of arc segments. When assembling the arc segments 3211 of the ring gear 32 and mounting the ring gear on the disc 10, the arc segments can be assembled and connected part by part or all at once. The multiple arc segments 3211 are placed on the multiple mounting seats 13, assembled into the multiple ring layers 321 stacked along the axial direction, and the splicing seams 321A of the adjacent arc segments 3211 of the adjacent ring layers 321 are staggered and aligned in layers, and the tooth profile, the positioning pin holes and the bolt holes of the transmission teeth are aligned, the pins 323 are inserted into the aligned positioning pin holes of each ring layer 321, the multiple ring layers 321 are connected together by the screws as threaded connections 322, and the multiple ring layers 321 and the mounting seats 13 are connected and fixed, thereby completing the assembly and formation of the entire ring gear 32 and the disc 10. Due to the multi-layer multi-segment staggered stacking in the thickness direction of the ring gear 32, the splicing seams 321A of the adjacent ring layers 321 are staggered along the circumferential direction of the ring gear 32, which ensures the overall strength of the ring gear 32. During the installation process, the multiple ring layers 321 are positioned by pins and connected by screws, so that the tooth profile of the transmission teeth of the multiple ring layers 321 is completely coincident, and the overall precision of the ring gear 32 meets the requirements.

[0073] The bridge 20 is arranged above the disc 10. The bridge 20 comprises a driving beam 21, a rotating trolley 22, two follower beams 23 and a supporting wheel 24. The driving beam 21 and the follower beams 23 each extend along the radial direction of the disc 10. The two follower beams 23 are arranged in line, and the driving beam 21 is fixed perpendicularly to the two follower beams 23. In this embodiment, the driving beam 21 and the follower beams 23 are each a box-shaped beam.

[0074] The rotating trolley 22 is movably supported on the gear ring 32 along the circumferential direction of the gear ring 32, and the radial outer end of the driving beam 21 is connected to the rotating trolley 22.

[0075] The rotating trolley 22 comprises a trolley body 221, a walking wheel 222 and a floating hanging wheel 223. The driving mechanism 33, the gear and bearing device 34 are mounted on the trolley body 221 of the rotating trolley 22, thereby being mounted on the bridge 20. The trolley body 221 is supported on the walking wheel 222, which is supported on the top surface of the gear ring 32 and can walk along the gear ring 32 as a track. The floating hanging wheel 223 is supported on the bottom surface of the gear ring 32, thereby cooperating with the walking wheel 222 to limit the rotating trolley 22 in the axial direction of the disc 10, i.e. to limit the driving mechanism 33, the bridge 20 and the matching devices mounted on the bridge 20 in the axial direction of the disc 10.

[0076] The supporting wheel 24 is mounted on the follower beam 23 and supported on the gear ring 32. As the driving beam 21 rotates following the rotating trolley 22, the supporting wheel 24 walks along the gear ring 32 as a track, and the follower beam 23 rotates synchronously with the driving beam 21.

[0077] The bridge 20 is used to mount various matching devices (not shown) matched with the disc 20. The matching devices include, for example, a stirrer, a conveyor, a temperature measuring assembly, a gallery bridge, etc.

[0078] In this embodiment, the various matching devices are mounted on the driving beam 21 and the two follower beams 23 of the bridge 20, which radiate from the center column 40 to the gear ring 32 on the disc 10. The center column 40 and the gear ring 32 jointly support the bridge 20 to rotate around the central axis of the disc 10 on the disc 10. The follower beams 23 of the bridge 20 are not necessary. In the case of arranging the follower beams 23, the number of the follower beams 23 is mainly determined by the matching devices to be mounted and the required positions. The gear ring 32 supports the weight of the bridge 20 as a track for the rotating trolley 22 and the supporting wheel 24. The driving mechanism drives the gear as the driving wheel 31 to mesh with the gear ring 32 to realize the rotation of the bridge 20 around the center column 40. The walking wheel 222 and the floating hanging wheel 223 respectively contact the upper and lower surfaces of the gear ring 32 to realize smooth and safe limiting in the axial direction of the gear ring 32.

[0084] The gear ring 32 is coaxially mounted on the plurality of mounting seats 13 of the disc 10, and the mounting seats 13 are plate-shaped. The surrounding part 12 may, for example, be made of concrete, and in this case, the plate-shaped mounting seats 13 can be mounted at the top of the surrounding part 12 by pre-buried manner. The top of the plate-shaped mounting seat 13 is provided with a threaded hole.

When assembling the arc segments 3211 of the ring gear 32 and mounting the ring gear 32 on the disc 10, the arc segments 3211 can be assembled and connected part by part or all at once. The arc segments 3211 are placed on the mounting seats 13, assembled into the multi-layer ring layers 321 stacked along the axial direction, and the splicing seams 321A of adjacent arc segments 3211 of adjacent ring layers 321 are staggered and aligned in layers, and the tooth profile of the driving teeth, the positioning pin holes and the bolt holes are aligned, the pins 323 are inserted into the aligned positioning pin holes of each ring layer 321, the screws are used as threaded connections 322 to connect the multi-layer ring layers 321 together, and the multi-layer ring layers 321 and the mounting seats 13 are connected and fixed, thereby completing the assembly and forming of the entire ring gear 32 and the disc 10.

[0087] Due to the multi-layer multi-segment staggered stacking manner in the thickness direction of the ring gear 32, the splicing seams 321A of adjacent ring layers 321 are staggered along the circumferential direction of the ring gear 32, which ensures the overall strength of the ring gear 32. During the mounting process, the multi-layer ring layers 321 are positioned by the pins and connected by the screws, so that the tooth profile of the driving teeth of the multi-layer ring layers 321 is completely coincided, and the overall precision of the ring gear 32 meets the requirements.

[0088] The bridge 20 is arranged above the disc 10. The bridge 20 includes a driving beam 21 and a rotating trolley 22. In the embodiment, the driving beam 21 is a truss beam.

[0089] The rotating trolley 22 is movably supported on the ring gear 32 along the circumferential direction of the ring gear 32, and the radially outer end of the driving beam 21 is connected to the rotating trolley 22.

[0090] The rotating trolley 22 comprises a trolley body 221, traveling wheels 222 and floating hanging wheels (not shown). The driving mechanism 33, pin wheels and bearing devices are installed on the trolley body 221 of the rotating trolley 22, thereby being installed on the bridge 20. The trolley body 221 is supported on the traveling wheels 222, which are supported on the top surface of the gear ring 32 and can travel along the gear ring 32 as a track. The floating hanging wheels are supported on the bottom surface of the gear ring 32, thereby cooperating with the traveling wheels 222 to limit the rotating trolley 22 in the axial direction of the disc 10, i.e. to limit the driving mechanism 33, the bridge 20 and the matched devices installed on the bridge 20 in the axial direction of the disc 10.

[0091] The bridge 20 is used to install various matched devices matched with the disc 20. The matched devices include, for example, a stirrer 50, a conveyor 60, a temperature measuring assembly (not shown), a gallery bridge (not shown) and the like.

[0092] In the embodiment, various matched devices are installed on the driving beam 21 of the bridge 20, and the center column 40 and the gear ring 32 jointly support the bridge 20 to rotate on the disc 10 around the central axis of the disc 10. The gear ring 32 supports the weight of the bridge 20 as the track of the rotating trolley 22 and the supporting wheel 24, and the driving mechanism 33 drives the pin wheels as the driving wheels 31 to mesh with the gear ring 32 to realize the rotation of the bridge 20 around the center column 40. The traveling wheels 222 and the floating hanging wheels respectively contact the upper and lower surfaces of the gear ring 32 to realize smooth and safe limiting in the axial direction of the gear ring 32.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent replacements, which should be covered in the technical solution range claimed by the present application.
