It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Please also read Figures 1 to 5 , the multi-bin trough digester provided by the present invention is now described. The multi-bin trough digester comprises a housing 1, a digestion tank 11, a conveying and stirring device 2, a transition chamber 3, a rotating disk 4 and a material beating rod group 5. There are multiple digestion tanks 11, which are arranged in sequence inside the housing 1, and the multiple digestion tanks 11 are connected to each other head to tail. The digestion tank 11 at the head end is provided with a liquid filling port 112 and a material filling port 111, and the digestion tank 11 at the tail end is provided with a discharge port; the conveying and stirring device 2 is installed inside the digestion tank 11, and is used to push the material to move inside the digestion tank 11 and stir the material; the transition chamber 3 is connected between two adjacent digestion tanks 11; the rotating disk 4 is rotatably arranged inside the transition chamber 3, and the axis of the rotating disk 4 is arranged along the length direction of the digestion tank 11; there are multiple material beating rod groups 5, and the multiple material beating rod groups 5 are evenly arranged on the rotating disk 4 along the circumference of the rotating disk 4, and are used to stir the material located inside the transition chamber 3.

[0019] Compared with the prior art, the multi-bin trough digester provided in this embodiment is provided with a housing 1, on which a plurality of digestion tanks 11 are installed, the length directions of the plurality of digestion tanks 11 are arranged along the same direction, and the plurality of digestion tanks 11 are arranged adjacent to each other in sequence. A conveying and stirring device 2 is arranged inside the digestion tank 11, and when the material is conveyed to the inside of the digestion tank 11, it can be stirred by the conveying and stirring device 2, and the material can be pushed along the conveying direction of the material. In the present application, a transition chamber 3 is provided between two adjacent digestion tanks 11, and the transition chamber 3 can realize the material being conveyed from the front digestion tank 11 to the inside of the rear digestion tank 11. A rotating disk 4 is rotatably arranged on the side wall of the transition chamber 3, and a plurality of groups of beating rod groups 5 are installed on the rotating disk 4. When the material is transported to the interior of the transition chamber 3, the rotating disk 4 can drive the beating rod group 5 to rotate in the interior of the transition chamber 3 around the axis of the rotating disk 4. On the one hand, the material can be sent to the interior of the digestion tank 11 at the rear, and at the same time, the material in the transition chamber 3 can be further dispersed and stirred, thereby improving the stirring effect of the entire digester, thereby improving the reaction effect of the material.

[0020] Specifically, in this embodiment, the bottom of the transition chamber 3 is an arc-shaped structure centered on the axis of the rotating disk 4. When the material-beating rod group 5 moves to the bottom of the transition chamber 3, the material-beating rod group 5 abuts against the bottom of the transition chamber 3. This facilitates the material inside the transition chamber 3 to be transported to the rear digestion tank 11. The rotating direction of the rotating disk 4 is the direction in which the material-beating rod group 5 is driven to transport the material to the rear digestion tank 11.

[0021] Specifically, in this embodiment, a moisture discharge cylinder is further provided on the top of the box body 1 .

[0022] In some embodiments, the above-mentioned material beating rod group 5 can be used as follows Figure 2 , Figure 3 and Figure 4 See also Figure 2 , Figure 3 and Figure 4 The beating rod group 5 includes a mounting disc 51 and a stirring rod 52. The mounting disc 51 is rotatably mounted on the rotating disc 4 and is spaced and parallel to the axis of the rotating disc 4; there are multiple stirring rods 52, and multiple stirring rods 52 are spaced and mounted on the mounting disc 51 along the circumference of the mounting disc 51, and the length direction of the stirring rods 52 is arranged along the axis direction of the mounting disc 51. The mounting disc 51 is rotatably mounted on the rotating disc 4, and the rotating axis of the mounting disc 51 is spaced and parallel to the rotating axis of the rotating disc 4. Multiple stirring rods 52 are mounted on the mounting disc 51. When the mounting disc 51 rotates on the rotating disc 4, it can drive the multiple stirring rods 52 to rotate, thereby further enhancing the stirring of the material.

[0023] Preferably, in this embodiment, one end of the stirring rod 52 is mounted on the mounting plate 51, and the other end is freely disposed inside the transition chamber 3. The stirring rod 52 is made of a material with a certain elasticity to prevent the stirring rod 52 from breaking during use.

A first gear 53 is fixedly connected to the mounting plate 51, and the first gear 53 is meshed with the gear plate 6. When the rotating plate 4 rotates, it will drive the mounting plate 51 and the first gear 53 to move, and through the meshing between the first gear 53 and the gear plate 6, when the rotating plate 4 rotates on the side wall of the transition chamber 3, it can synchronously drive multiple mounting plates 51 to rotate together, the structure is simple, and the same driving source can synchronously drive the rotating plate 4 and the mounting plate 51 to rotate. At the same time, when the rotating plate 4 rotates, the mounting plate 51 will drive the stirring rod 52 to rotate together, thereby further enhancing the stirring effect.

[0025] In some embodiments, the stirring rod 52 may be Figure 3 See the structure shown. Figure 3, the position of the stirring rod 52 on the mounting disk 51 has the freedom to be adjusted radially along the mounting disk 51. One end of the stirring rod 52 is mounted on the mounting disk 51, and the other end is extended to the inside of the transition chamber 3. When the mounting disk 51 rotates, the stirring rod 52 will move radially along the mounting disk 51 on the mounting disk 51. Thereby, it is possible to prevent the material from being stuck between the multiple stirring rods 52, by the stirring rod 52 moving radially along the mounting disk 51 on the mounting disk 51. If there is agglomeration during the stirring process, on the one hand, the stirring rod 52 is driven by the rotation of the mounting disk 51 to break the agglomeration, and at the same time, when the agglomeration moves between the multiple stirring rods 52 on the mounting disk 51, the stirring rod 52 can be moved radially along the mounting disk 51 to achieve crushing of the agglomeration or fall from between the multiple stirring rods 52, thereby preventing the agglomeration from being stuck between the multiple stirring rods 52.

Figure 3 , the rotating disk 4 is provided with an annular groove 521 for accommodating the end of the stirring rod 52, and the projection of the annular groove 521 along the axis direction of the rotating disk 4 is an elliptical structure with the center on the axis of the rotating disk 4. The mounting disk 51 is provided with a clearance groove 511 for avoiding the movement of the stirring rod 52, and the stirring rod 52 is slidably arranged inside the clearance groove 511. The mounting disk 51 is provided with a clearance groove 511 for installing the stirring rod 52, and the length direction of the clearance groove 511 is arranged along the radial direction of the mounting disk 51. A moving block slidably arranged inside the clearance groove 511 is installed in the middle of the stirring rod 52, and the stirring rod 52 can move along the radial direction of the mounting disk 51 on the mounting disk 51 through the guidance between the clearance groove 511 and the moving block. The rotating disk 4 is provided with an annular groove 521, and the annular groove 521 is an elliptical structure as a whole, and the circular shape of the annular groove 521 is located on the axis of the rotating disk 4. Preferably, four stirring rods 52 are mounted on the same mounting disk 51, and the four stirring rods 52 are evenly spaced and arranged on the mounting disk 51 along the circumference of the mounting disk 51. When the mounting disk 51 rotates, the ends of the stirring rods 52 move along the shape of the annular groove 521, and the two opposing stirring rods 52 move in a direction of being relatively close to or relatively far away from each other, so that when the mounting disk 51 rotates on the rotating disk 4, it can drive the multiple stirring rods 52 to rotate and simultaneously drive the stirring rods 52 to move along the radial direction of the mounting disk 51.

[0027] In some embodiments, the conveying and stirring device 2 can be used as follows: Figure 2 See the structure shown. Figure 2The conveying and stirring device 2 includes a driving shaft 21 and a stirring arm 23.

The bottom of the digestion tank 11 is an arc structure adapted to the shape of the spiral blade 22. When the driving shaft 21 drives the bolt blade to rotate, the spiral blade 22 can push the material to move along the length direction of the digestion tank 11. The spiral blade 22 is wound around the outer side of the driving shaft 21, and is spaced from the driving shaft 21, and both ends of the spiral blade 22 are respectively fixedly mounted on the driving shaft 21, and the driving shaft 21 is driven to rotate by a motor. The stirring arm 23 is fixedly mounted on the driving shaft 21, and the stirring arm 23 is located at the gap between the spiral blades 22, so that the material is broken during the material conveying process. Further improve the stirring effect.

[0028] In some embodiments, the drive shaft 21 may be Figure 2 , Figure 4 and Figure 5 See also Figure 2 , Figure 4 and Figure 5 The end of the driving shaft 21 is fixedly mounted with a second gear 211, and the second gear 211 is also transmission-connected with a transmission gear 7, and the transmission gear 7 is transmission-connected with the rotating disk 4.

[0029] Specifically, in this embodiment, the rotating disk 4 includes a mounting portion for mounting the punching rod assembly 5 and a gear portion for meshing with the transmission gear 7. The mounting portion is located inside the box body 1, and the gear portion is located outside the box body 1.

[0030] In some embodiments, the digestion tank 11 may be Figure 4 See the structure shown. Figure 4The discharge end of the digester 11 is provided with an arc-shaped discharge trough 8, which is lower than the bottom of the digester 11, and a material-pickup assembly 9 for pickup material into the transition chamber 3 is provided inside the arc-shaped discharge trough 8. The discharge end of the digester 11 is provided with an arc-shaped discharge trough 8. The material inside the digester 11 can be moved to the inside of the arc-shaped discharge trough 8 by the pushing of the spiral blade 22. The material inside the arc-shaped discharge trough 8 is then picked into the transition chamber 3 by the material-pickup assembly 9. The material inside the transition chamber 3 can be guided and transported to the inside of the digester 11 at the rear through the material-beating rod group 5, thereby assisting the transportation of the material.

[0031] In some embodiments, the material shifting assembly 9 can be used as follows: Figure 4 , Figure 5 See also Figure 4 , Figure 5 The material-digging assembly 9 includes a material-digging shaft 91 and a material-digging plate 92.

And the height of the material-digging shaft 91 is lower than the height of the axis of the rotating disk 4. It can prevent the material-digging plate 92 from interfering with the stirring rod 52 on the material-beating rod group 5.

[0032] Specifically, in this embodiment, a plurality of material-diverting plates 92 are fixedly installed on the outer side of the material-diverting shaft 91 . When the material-diverting shaft 91 rotates, the material inside the arc-shaped discharge chute 8 can be diverted to the transition chamber 3 through the material-diverting plates 92 .

[0033] Specifically, in this embodiment, the rotation direction of the rotating disk 4 is the same as the rotation direction of the material-dispensing shaft 91 , so that the materials can be moved in the same direction.
