[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Please refer to Figures 1 to 5 , and now the multi-chamber trough-type digester provided by the present invention will be described. The multi-chamber trough-type digester includes a box body 1, a digestion trough 11, a conveying and stirring device 2, a transition chamber 3, a rotating disk 4 and a material beating rod group 5. The number of the digestion troughs 11 is multiple, and the multiple digestion troughs 11 are arranged in sequence inside the box body 1, and the multiple digestion troughs 11 are connected end to end. A liquid adding port 112 and a feeding port 111 are arranged on the digestion trough 11 at the front end, and a discharging port is arranged on the digestion trough 11 at the rear end; the conveying and stirring device 2 is installed inside the digestion trough 11 for pushing the material to move inside the digestion trough 11 and stirring the material; the transition chamber 3 is communicated between two adjacent digestion troughs 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 trough 11; the number of the material beating rod groups 5 is multiple, and the multiple material beating rod groups 5 are evenly arranged on the rotating disk 4 along the circumferential direction of the rotating disk 4 for stirring the material located inside the transition chamber 3.

[0036] Compared with the prior art, the multi-chamber trough-type digester provided in this embodiment is provided with a box body 1, and a plurality of digestion troughs 11 are installed on the box body 1. The length directions of the plurality of digestion troughs 11 are all arranged in the same direction, and the plurality of digestion troughs 11 are arranged adjacent to each other in sequence. A conveying and stirring device 2 is arranged inside the digestion trough 11. When the material is conveyed into the digestion trough 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 this application, a transition chamber 3 is communicated between two adjacent digestion troughs 11. Through the transition chamber 3, the material can be conveyed from the front digestion trough 11 into the rear digestion trough 11. And a rotating disk 4 is rotatably arranged on the side wall of the transition chamber 3, and a plurality of groups of material beating rod assemblies 5 are installed on the rotating disk 4. When the material is conveyed into the transition chamber 3, the rotation of the rotating disk 4 can drive the material beating rod group 5 to rotate around the axis of the rotating disk 4 inside the transition chamber 3. On the one hand, the material can be dialed into the rear digestion trough 11, and at the same time, the material inside the transition chamber 3 can be further dispersed and stirred, improving the stirring effect of the entire digester, thereby improving the reaction effect of the material.

[0037] 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 feeding rod group 5 moves to the bottom of the transition chamber 3, the material feeding rod group 5 abuts against the bottom of the transition chamber 3. Thus, it is convenient to convey the material located inside the transition chamber 3 into the rear digestion tank 11. The rotating direction of the rotating disk 4 is the direction of driving the material feeding rod group 5 to convey the material into the rear digestion tank 11.

[0038] Specifically, in this embodiment, a moisture exhaust cylinder is further provided on the top of the box body 1.

[0039] In some embodiments, the above-mentioned material feeding rod group 5 can adopt structures such as Figure 2 , Figure 3 and Figure 4 as shown. Referring to Figure 2 , Figure 3 and Figure 4 , the material feeding rod group 5 includes a mounting disk 51 and stirring rods 52. The mounting disk 51 is rotatably arranged on the rotating disk 4 and is arranged at a parallel interval with the axis of the rotating disk 4; the number of the stirring rods 52 is multiple, and the multiple stirring rods 52 are installed on the mounting disk 51 at intervals along the circumferential direction of the mounting disk 51, and the length direction of the stirring rods 52 is arranged along the axis direction of the mounting disk 51. The mounting disk 51 is rotatably arranged on the rotating disk 4, and the rotating shaft of the mounting disk 51 is arranged at a parallel interval with the rotating shaft of the rotating disk 4. A plurality of stirring rods 52 are installed on the mounting disk 51. When the mounting disk 51 rotates on the rotating disk 4, it can drive the plurality of stirring rods 52 to rotate, thereby further enhancing the stirring of the material.

[0040] Preferably, in this embodiment, one end of the stirring rod 52 is installed on the mounting disk 51, and the other end is freely arranged 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.

[0041] In some embodiments, the above-mentioned mounting disk 51 can adopt structures such as Figure 4 as shown. Referring to Figure 4, a gear disc 6 is fixedly installed on the side wall of the transition cavity 3. The gear disc 6 is coaxially arranged with the rotating disc 4. A first gear 53 meshing with the gear disc 6 is fixedly installed on the rotating shaft of the mounting disc 51. A fixed shaft is fixedly installed inside the transition cavity 3. One end of the fixed shaft is fixedly installed on the inner wall of the transition cavity 3, and the other end of the fixed shaft is fixedly installed with the gear disc 6. The rotating disc 4 is sleeved outside the gear disc 6 and rotates relative to the gear disc 6. A first gear 53 is fixedly connected to the mounting disc 51, and the first gear 53 is meshed with the gear disc 6. When the rotating disc 4 rotates, it will drive the mounting disc 51 and the first gear 53 to move, and through the meshing between the first gear 53 and the gear disc 6, when the rotating disc 4 rotates on the side wall of the transition cavity 3, multiple mounting discs 51 can be synchronously driven to rotate together. The structure is simple, and the same driving source can synchronously drive the rotating disc 4 and the mounting disc 51 to rotate. At the same time, when the rotating disc 4 rotates, the mounting disc 51 will drive the stirring rod 52 to rotate together, thereby further enhancing the stirring effect.

[0042] In some embodiments, the above-mentioned stirring rod 52 can adopt a structure as Figure 3 shown. Refer to Figure 3 , the position of the stirring rod 52 on the mounting disc 51 has the freedom to adjust radially along the mounting disc 51. One end of the stirring rod 52 is installed on the mounting disc 51, and the other end extends into the transition cavity 3. When the mounting disc 51 rotates, the stirring rod 52 will move radially along the mounting disc 51 on the mounting disc 51. Thereby, it can prevent the material from being stuck between multiple stirring rods 52, and the stirring rod 52 moves radially along the mounting disc 51 on the mounting disc 51. When there is a caking situation during the stirring process, on the one hand, the rotation of the mounting disc 51 drives the stirring rod 52 to break up the caking. At the same time, when the caking moves between multiple stirring rods 52 on the mounting disc 51, the caking can be crushed or dropped from between multiple stirring rods 52 by the radial movement of the stirring rod 52 along the mounting disc 51, avoiding the caking being stuck between multiple stirring rods 52.

[0043] In some embodiments, the above-mentioned rotating disc 4 can adopt a structure as Figure 3 shown. Refer to Figure 3, a circular groove 521 for accommodating the end of the stirring rod 52 is recessed on the rotating disk 4. The projection of the circular 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. A relief groove 511 for avoiding the movement of the stirring rod 52 is provided on the mounting disk 51, and the stirring rod 52 is slidably arranged inside the relief groove 511. A relief groove 511 for installing the stirring rod 52 is provided on the mounting disk 51, and the length direction of the relief groove 511 is arranged along the radial direction of the mounting disk 51. A moving block slidably arranged inside the relief groove 511 is installed in the middle of the stirring rod 52. Through the guidance between the relief groove 511 and the moving block, the stirring rod 52 can move along the radial direction of the mounting disk 51 on the mounting disk 51. A circular groove 521 is recessed on the rotating disk 4. The circular groove 521 is an overall elliptical structure, and the circle of the circular groove 521 is located on the axis of the rotating disk 4. Preferably, four stirring rods 52 are installed on the same mounting disk 51, and the four stirring rods 52 are evenly spaced along the circumferential direction of the mounting disk 51 on the mounting disk 51. When the mounting disk 51 rotates, the end of the stirring rod 52 moves along with the shape of the circular groove 521, and the two opposite stirring rods 52 move in the direction of approaching or moving away from each other. Thus, when the mounting disk 51 rotates on the rotating disk 4, it can not only drive multiple stirring rods 52 to rotate, but also drive the stirring rods 52 to move along the radial direction of the mounting disk 51.

[0044] In some embodiments, the above-mentioned conveying and stirring device 2 can adopt the structure as Figure 2 shown. Refer to Figure 2 , the conveying and stirring device 2 includes a driving shaft 21 and a stirring arm 23. The driving shaft 21 is rotatably arranged inside the digestion tank 11. A spiral blade 22 is wound around the outside of the driving shaft 21, and both ends of the spiral blade 22 are fixedly installed on the driving shaft 21; one end of the stirring arm 23 is fixedly installed on the driving shaft 21, and the other end extends away from the driving shaft 21. The bottom of the digestion tank 11 is an arc-shaped structure adapted to the outer 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 outside of the driving shaft 21 and is spaced from the driving shaft 21, and both ends of the spiral blade 22 are respectively fixedly installed on the driving shaft 21. The driving shaft 21 is driven to rotate by a motor. The stirring arm 23 is fixedly installed on the driving shaft 21 and is located at the gap of the spiral blade 22, so as to break up the material during the material conveying process and further improve the stirring effect.

[0045] In some embodiments, the above-mentioned driving shaft 21 can adopt the structure as Figure 2 , Figure 4 and Figure 5 shown. Refer to Figure 2 , Figure 4 and Figure 5, a second gear 211 is fixedly installed at the end of the drive shaft 21. The second gear 211 is also drivingly connected to a transmission gear 7, and the transmission gear 7 is drivingly connected to the rotating disk 4. A second gear 211 is fixedly installed at the end of the drive shaft 21, and teeth meshing with the transmission gear 7 are provided on the outer side of the rotating disk 4. A transmission gear 7 is also rotatably provided on the side wall of the box body 1, and the transmission gear 7 is meshed with the second gear 211 and the rotating disk 4 respectively. Thus, when the drive shaft 21 rotates, the rotating disk 4 can be driven to rotate synchronously, thereby optimizing the structure and reducing the use of the drive source.

[0046] Specifically, in this embodiment, the rotating disk 4 includes a mounting portion for mounting the material pushing rod group 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.

[0047] In some embodiments, the above digestion tank 11 can adopt a structure as Figure 4 shown. Refer to Figure 4 , an arc-shaped discharge chute 8 is provided at the discharge end of the digestion tank 11. The arc-shaped discharge chute 8 is lower than the bottom of the digestion tank 11, and a material pushing component 9 for pushing the material into the transition cavity 3 is provided inside the arc-shaped discharge chute 8. An arc-shaped discharge chute 8 is provided at the discharge end of the digestion tank 11. The material located inside the digestion tank 11 can be moved into the arc-shaped discharge chute 8 through the pushing of the spiral blade 22. Then, the material pushing component 9 pushes the material inside the arc-shaped discharge chute 8 into the transition cavity 3. The material inside the transition cavity 3 can be guided and conveyed to the digestion tank 11 at the rear through the material pushing rod group 5, thereby assisting the conveyance of the material.

[0048] In some embodiments, the above material pushing component 9 can adopt a structure as Figure 4 , Figure 5 shown. Refer to Figure 4 , Figure 5 together. The material pushing component 9 includes a material pushing shaft 91 and a material pushing plate 92. The material pushing shaft 91 is rotatably provided inside the arc-shaped discharge chute 8 and is arranged parallel to and spaced from the drive shaft 21; the number of the material pushing plates 92 is multiple, and the multiple material pushing plates 92 are evenly arranged at intervals along the circumferential direction of the material pushing shaft 91 on the outer side of the material pushing shaft 91, and the material pushing plates 92 abut against the inner wall of the arc-shaped discharge chute 8. The material pushing shaft 91 is rotatably provided inside the arc-shaped discharge chute 8, and the material pushing shaft 91 is located below the drive shaft 21. And the height of the material pushing shaft 91 is lower than the height of the axis of the rotating disk 4. This can prevent the material pushing plate 92 from interfering with the stirring rod 52 on the material pushing rod group 5.

[0049] Specifically, in this embodiment, a plurality of material pushing plates 92 are fixedly installed on the outer side of the material pushing shaft 91. When the material pushing shaft 91 rotates, the material inside the arc-shaped discharge chute 8 can be pushed into the transition cavity 3 through the material pushing plates 92.

[0050] Specifically, in this embodiment, the rotation direction of the rotating disk 4 is the same as that of the material feeding shaft 91, so that the material can be moved in the same direction.

[0051] In some embodiments, the above-mentioned material feeding shaft 91 can adopt a structure as Figure 4 , Figure 5 shown. Referring to Figure 4 , Figure 5 together, a third gear 911 is fixedly installed on the material feeding shaft 91, and the third gear 911 is in transmission connection with the transmission gear 7. The third gear 911 is rotatably arranged on the box body 1. The third gear 911 is fixedly installed on the material feeding shaft 91, and the second gear 211, the third gear 911 and the rotating disk 4 are all meshed with the transmission gear 7, so as to realize that the drive shaft 21 can drive the rotating disk 4 and the material feeding shaft 91 to rotate synchronously. It is realized that the same drive motor can drive multiple units to work synchronously. The structure is simple, and the processing cost and occupied volume of the equipment are saved.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
