[0028] The garbage treatment device for garbage power generation provided by the present application will be explained and described below in conjunction with the drawings and specific embodiments.

[0029] Embodiment one of the garbage disposal device for garbage power generation of the present application: refer to Figures 1 to 7 As shown in the figure, the garbage disposal device for garbage power generation mainly comprises a rack 100, a treatment bin 200, a crushing mechanism, a driving mechanism, a swing mechanism and a screen 400, the treatment bin 200 is rotationally assembled on the rack 100, the rotation axis of the treatment bin 200 extends horizontally along the front-rear direction, the crushing mechanism and the screen 400 are arranged in the treatment bin 200, the swing mechanism drives the treatment bin 200 to reciprocate on the rack 100, and in turn drives the crushing mechanism and the screen 400 to synchronously reciprocate around the rotation axis of the treatment bin.

[0030] The front and rear ends of the treatment bin 200 are coaxially fixedly provided with swing shafts 260, the treatment bin 200 is supported and arranged on the rack 100 through the swing shafts 260, the swing shafts 260 are rotationally matched with the rack 100, and the rotation axis of the swing shafts 260 extends horizontally along the front-rear direction, so that the treatment bin 200 can reciprocate on the rack 100.

[0031] The swing mechanism comprises a reciprocating motor 500 and a swing assembly, in the embodiment, the swing assembly mainly comprises a swing rod 510, the output shaft 501 of the reciprocating motor 500 is fixedly connected with one end of the swing rod 510, the output shaft 501 of the reciprocating motor 500 alternately reciprocates along the clockwise direction and the counterclockwise direction at a set angle α, and in turn drives the swing rod 510 to swing left and right, wherein α is an acute angle.

[0032] The swing shafts 260 are coaxially fixedly provided with rotating wheels 270, the rotating wheels 270 are provided with matching protrusions 271 at positions deviated from the shaft centers, the swing rod 510 is correspondingly provided with a matching long hole 511, the matching long hole 511 extends along the length direction of the swing rod 510, the matching protrusions 271 on the rotating wheels 270 extend into the matching long hole 511 and are guided matched with the hole wall of the matching long hole 511. With the swing rod 510 swinging left and right, the hole wall of the matching long hole 511 pushes the matching protrusions 271 to move, so as to drive the rotating wheels 270 to rotate, the rotating wheels 270 rotating drive the swing shafts 260 to synchronously rotate, and in turn make the treatment bin 200 reciprocate on the rack 100. In the embodiment, the amplitude of the reciprocation of the treatment bin 200 is kept between counterclockwise rotation of 30° and clockwise rotation of 30°, that is, the maximum rotation angle β of the reciprocation of the treatment bin 200 is 30°.

[0033] The rack 100 has a cavity wall 120 which is guided with the left and right side walls of the processing bin 200. The cavity wall 120 of the rack 100 and the left and right side walls of the processing bin 200 are all arc-shaped wall surfaces. During the reciprocating rotation of the processing bin 200, the cavity wall 120 of the rack 100 is guided with the left and right side walls of the processing bin 200. The cavity wall 120 of the rack 100 is provided with a sliding protrusion 130, and the left and right side walls of the processing bin 200 are correspondingly provided with a sliding groove 250. The sliding protrusion 130 is guided with the sliding groove 250. With the reciprocating rotation of the processing bin 200 on the rack 100, the sliding groove 250 on the left and right side walls of the processing bin 200 is guided to move relative to the sliding protrusion 130 to guide the reciprocating rotation stroke of the processing bin 200, avoid the deviation of the swing axis 260 of the processing bin 200, and ensure the operation stability of the structure. When the swing angle of the processing bin 200 reaches the maximum set value, the sliding groove 250 is stopped with the sliding protrusion 130 to limit the swing angle of the processing bin 200 and prevent the swing amplitude of the processing bin 200 from being too large to damage the structure.

[0034] The processing bin 200 has a crushed material cavity and a mounting cavity which are arranged on the front and rear sides of the crushed material cavity and are separated by a partition plate 220. The top of the crushed material cavity is provided with a feeding port 210 which communicates the crushed material cavity with the outside, and the materials to be crushed are fed into the crushed material cavity through the feeding port 210. The rack 100 above the feeding port 210 is fixedly provided with a feeding hopper 110 which is an expanding structure with a large upper part and a small lower part to facilitate feeding into the processing bin 200. The top of the mounting cavity is provided with an inspection port to facilitate the installation and inspection of the driving mechanism, and the inspection port is provided with an end cover 241 which is used to close the inspection port to prevent sundries from entering the mounting cavity through the inspection port.

[0035] The crushing mechanism and the screen 400 are installed in the crushed material cavity, and the screen 400 is arranged below the crushing mechanism. In the crushed material cavity, the materials fed through the feeding port 210 fall onto the screen 400 after being crushed by the crushing mechanism. The material particles smaller than the set size can fall through the screen holes 410 of the screen 400, and the remaining materials with larger sizes are accumulated on the screen 400 and are re-rolled into the crushing mechanism for further crushing until the size of the materials is crushed to be smaller than the set size and falls through the screen holes 410 of the screen 400. A material falling bin (prior art, not shown in the figure) is arranged below the screen 400 to collect the materials falling through the screen 400.

[0036] The crushing mechanism includes four groups of crushing knives, each group of crushing knives including a knife shaft and a plurality of knife blades, the knife shafts of the crushing knives extending forward and backward and being rotatably assembled on the side wall of the processing bin 200, and the knife blades of the same group of crushing knives being equidistantly arranged on the outer circumferential surface of the knife shaft. The four knife shafts are arranged side by side and parallel to each other, the knife blades of adjacent knife shafts are arranged in a staggered manner, and the knife blades on the knife shafts extend into the space between two knife blades of the adjacent knife shaft. In use, the knife shafts drive the knife blades to rotate, so that the knife blades of the adjacent knife shafts are engaged in a staggered manner to shear and crush the material in the processing bin 200.

[0037] The driving mechanism has two groups, which are arranged in the front and rear mounting cavities in the processing bin 200, and the mounting cavities are fixedly provided with mounting frames 240 on the side wall of the corresponding partition plate 220, and the driving mechanism is fixedly arranged on the mounting frame 240 to drive the crushing mechanism to operate. The driving mechanism mainly includes a driving motor 630 and a transmission assembly, the driving motor 630 is in transmission connection with the knife shaft through the transmission assembly to drive the knife shaft to rotate, thereby crushing the material in the crushing chamber. In this embodiment, the transmission assembly includes a gear set composed of a plurality of transmission gears 640.

[0038] Specifically, the four groups of crushing knives are sequentially the first crushing knife 310, the second crushing knife 320, the third crushing knife 330 and the fourth crushing knife 340 from left to right, the first crushing knife 310 and the fourth crushing knife 340 are arranged symmetrically left and right, and the second crushing knife 320 and the third crushing knife 330 are arranged symmetrically left and right. The first crushing knife 310 is higher than the second crushing knife 320, so that the first crushing knife 310 can roll the material to the upper side of the second crushing knife 320 when rotating. The fourth crushing knife 340 is higher than the third crushing knife 330, so that the fourth crushing knife 340 can roll the material to the upper side of the third crushing knife 330 when rotating.

[0039] Further, the two groups of driving mechanisms are respectively the first driving mechanism 610 and the second driving mechanism 620, the first driving mechanism 610 is arranged in the mounting cavity at the rear of the crushing chamber to drive the first crushing knife 310 and the second crushing knife 320 to rotate, and the second driving mechanism 620 is arranged in the mounting cavity at the front of the crushing chamber to drive the third crushing knife 330 and the fourth crushing knife 340 to rotate. From the front side view, the first crushing knife 310 and the second crushing knife 320 rotate clockwise, and the third crushing knife 330 and the fourth crushing knife 340 rotate counterclockwise, so that the first crushing knife 310 and the fourth crushing knife 340 can effectively roll the material on the screen 400 to the upper side of the crushing mechanism, which helps to improve the crushing efficiency.

[0040] The screen 400 screens the material falling on the upper surface of the screen 400 through the screen holes 410 of a set size, and the material smaller than the set size can fall through the screen holes 410 to the material falling bin below the screen 400, and the material larger than the set size is intercepted by the screen 400 and is re-fed to the crushing mechanism above the crushing knives to be crushed again.

[0041] The upper surface of the screen 400 has a lower recess 420 and a matching portion 430 extending front and back and parallel to the knife shaft of the crushing knives. The lower recess 420 is arranged at the middle position of the screen 400 and corresponds to the positions of the second crushing knife 320 and the third crushing knife 330, and the cross section of the lower recess 420 is arc-shaped and concave downward, so that the material falling on the screen 400 moves and gathers to the lowest point of the lower recess 420 under the action of gravity. The matching portion 430 is arranged on the left and right sides of the lower recess 420 and corresponds to the positions of the first crushing knife 310 and the fourth crushing knife 340, and the cross section shape of the matching portion 430 is the same as the lower profile of the first crushing knife 310 and the fourth crushing knife 340, and the matching portion 430 is in close contact with the lower part of the first crushing knife 310 and the fourth crushing knife 340, so that the first crushing knife 310 and the fourth crushing knife 340 can effectively re-feed the material on the matching portion 430 to the upper part of the crushing mechanism to be crushed again.

[0042] In the left-right direction, the height of the upper surface of the screen 400 gradually decreases from both sides to the middle, so that the material falling on the screen 400 gathers to the lower recess 420. In this process, the lower recess 420 extending front and back can automatically correct the posture of the long strip-shaped, cylindrical and other longer materials, so that they gradually tend to extend front and back, facilitating the feeding and effective crushing of the material by the crushing knives.

[0043] With the reciprocating rotation of the screen 400 around the rotation axis of the treatment bin, the screen 400 can effectively screen and correct the posture of the material, avoid the accumulation of the material to hinder the crushing qualified material from falling through the screen 400, and ensure the effective feeding and crushing of the crushing knives to the material not completely crushed. At the same time, in the process of reciprocating rotation of the screen 400, the material corrected in posture by the lower recess 420 can be re-fed to the matching portion 430 area below the first crushing knife 310 and the second crushing knife 320, and then be re-fed by the crushing knives to the crushing mechanism above to participate in crushing, thereby greatly improving the crushing effect and efficiency of the material.

[0044] The garbage processing device for garbage power generation of the present application will be further described below in conjunction with the specific use process. Figures 1 to 7

[0045] ​Firstly, the material to be crushed is put into the crushing cavity 230 of the processing bin 200 through the feeding hopper 110, and the driving mechanism installed in the cavity drives the four sets of crushing knives to rotate to shear and crush the material in the crushing cavity 230. Most of the material after the first crushing is torn into long strips and falls onto the screen 400 below the crushing knives.

[0046] Since the height of the upper surface of the screen 400 gradually decreases from both sides to the middle, and the processing bin 200 is continuously reciprocated by the swinging mechanism, the material falling onto the screen 400 tends to move to the lowest part of the upper surface of the screen 400 under the action of gravity. In the process of moving on the screen 400, the material crushed to be smaller than the set size falls through the screen hole 410 of the screen 400 into the material falling bin below the screen 400, and the remaining material with a larger size is gathered in the lower concave part 420 of the upper surface of the screen 400.

[0047] The continuous reciprocation of the screen 400 can overturn the material to avoid the material smaller than the set size being blocked by the remaining material and failing to fall smoothly through the screen hole 410, ensuring the screening effect and avoiding excessive accumulation of the material.

[0048] Since the cross section of the lower concave part 420 is an arc concave shape and extends forward and backward, the material gathered in the lower concave part 420 gradually deflects in the process of moving to the lowest part, changes to the posture of "extending in the length direction along the front and back direction", so that the posture of the long strip-shaped material is adjusted to the state perpendicular to the blade of the crushing knife, facilitating the crushing mechanism to crush the material again.

[0049] With the reciprocation of the screen 400 following the processing bin, the material on the lower concave part 420 after the posture correction moves to the matching part 430 on both sides, and then is re-wound to the crushing mechanism above by the first crushing knife 310 or the fourth crushing knife 340 to participate in crushing again. It can effectively avoid the long strip-shaped material being jammed between the two blades, and improve the crushing effect and crushing efficiency of the material.

[0050] Of course, the garbage processing device for garbage power generation of the present application is not limited to the above-mentioned embodiments, and the following provides several other embodiments different from the garbage processing device for garbage power generation in the above-mentioned embodiments.

[0051] In other embodiments of the garbage processing device for garbage power generation of the present application, different from the above-mentioned embodiments: the crushing mechanism can also include only two sets of crushing knives, and the material in the processing bin is crushed by the reverse shearing of the two sets of crushing knives.

[0052] In other embodiments of the waste disposal device for waste power generation of the present application, different from the above embodiments, when four sets of crushing knives are arranged in the crushing mechanism, the rotating directions of the crushing knives can also be arranged in other forms. For example, in the front side view, the first crushing knife and the third crushing knife rotate clockwise, and the second crushing knife and the fourth crushing knife rotate counterclockwise, and the materials are crushed by the shearing between the first crushing knife and the second crushing knife and between the third crushing knife and the fourth crushing knife, respectively.

[0053] In other embodiments of the waste disposal device for waste power generation of the present application, different from the above embodiments, the cross section of the lower concave part of the upper surface of the screen can not be arc-shaped, but can also be V-shaped or other shapes, as long as the height of the lower concave part gradually decreases from both sides to the middle. The lower concave part and the matching part can also be arranged at intervals.

[0054] In other embodiments of the waste disposal device for waste power generation of the present application, different from the above embodiments, the swinging mechanism can also be arranged in other structures. For example, lifting assemblies are arranged on both sides of the treatment bin, and the two sides of the treatment bin are alternately lifted by the lifting assemblies, so that the treatment bin rotates back and forth. The lifting assembly can be a lead screw structure with a reciprocating stroke or a hydraulic drive rod structure. Alternatively, a drive rod is engaged with the swing shaft, and the drive rod reciprocates to drive the swing shaft to rotate back and forth, thereby realizing the reciprocating rotation of the treatment bin.

[0055] In other embodiments of the waste disposal device for waste power generation of the present application, different from the above embodiments, the maximum rotation angle β of the treatment bin can not be 30°, but can also be 45° or 60°, as long as β is an acute angle.

[0056] In other embodiments of the waste disposal device for waste power generation of the present application, different from the above embodiments, the driving mechanism can also be arranged in only one set. One set of driving mechanism drives multiple sets of crushing knives to rotate through a transmission assembly, or two or more sets of driving mechanisms are arranged corresponding to the number of crushing knives to drive the crushing knives to rotate one by one. The driving mechanism can also be directly fixed on the outer wall of the treatment bin.

3. The waste treatment device for waste-to-energy power generation according to claim 2, characterized in that, The four sets of crushing blades are arranged from left to right as the first crushing blade, the second crushing blade, the third crushing blade, and the fourth crushing blade. The first and fourth crushing blades are arranged symmetrically on the left and right, and the second and third crushing blades are arranged symmetrically on the left and right. From a frontal viewpoint, the first and second crushing blades rotate clockwise, with the first crushing blade higher than the second crushing blade, so that the first crushing blade can roll the material above the second crushing blade when rotating. The third and fourth crushing blades rotate counterclockwise, with the fourth crushing blade higher than the third crushing blade, so that the fourth crushing blade can roll the material above the third crushing blade when rotating.

4. The waste treatment device for waste-to-energy power generation according to claim 3, characterized in that, The recessed portion is located in the middle of the screen, and the mating portion is located adjacent to both sides of the recessed portion. Both the recessed portion and the mating portion extend in the front-back direction. The mating portion is fitted to the surface contour of the lower part of the crushing mechanism so that the blade can roll the material on the mating portion during rotation.

5. The waste treatment device for waste-to-energy power generation according to claim 1, characterized in that, The processing chamber is fixedly mounted on a swing shaft at both the front and rear ends. The processing chamber is supported on the frame by the swing shaft. The swing shaft is rotatably engaged with the frame. The axis of rotation of the swing shaft extends horizontally in the front-rear direction so that the processing chamber can reciprocate on the frame.

6. The waste treatment device for waste-to-energy power generation according to claim 5, characterized in that, The swing mechanism includes a reciprocating motor and a swing assembly. The reciprocating motor is connected to the processing chamber via the swing assembly to drive the processing chamber to rotate back and forth on the frame.

7. The waste treatment device for waste-to-energy power generation according to claim 6, characterized in that, A rotating wheel is coaxially fixed on the swing shaft, and a mating protrusion is provided on the rotating wheel at a position off the axis. The swing assembly includes a swing rod, and a mating elongated hole is provided on the swing rod. The mating elongated hole extends along the length direction of the swing rod, and the mating protrusion is guided and mated with the mating elongated hole. The output shaft of the reciprocating motor is fixedly connected to one end of the swing rod. The output shaft of the reciprocating motor rotates alternately in the clockwise and counterclockwise directions at a set angle α, thereby driving the swing rod to swing left and right. α is an acute angle. As the swing arm swings left and right, the wall of the mating elongated hole pushes the mating protrusion to move, thereby driving the rotating wheel to rotate. The rotating wheel drives the swing shaft to rotate synchronously, thus causing the processing chamber to swing left and right on the frame.

8. The waste treatment device for waste-to-energy power generation according to claim 7, characterized in that, The maximum rotation angle of the processing chamber reciprocating on the frame is β, where β is an acute angle.

9. The waste treatment device for waste-to-energy power generation according to claim 8, characterized in that, The frame has an inner cavity wall that guides and cooperates with the left and right side walls of the processing chamber. The inner cavity wall is provided with sliding protrusions, and the left and right side walls of the processing chamber are respectively provided with sliding grooves. The sliding protrusions and sliding grooves are guided and cooperated with each other. When the processing chamber reciprocates on the frame, the sliding protrusion can guide the sliding groove to move, thereby guiding the reciprocating rotation stroke of the processing chamber. When the processing chamber swings to the left or right to the maximum rotation angle, the sliding groove and the sliding protrusion cooperate to stop and prevent the swing amplitude of the processing chamber from being too large.

10. The waste treatment device for waste-to-energy generation according to any one of claims 1-9, characterized in that, The processing chamber has a crushing chamber and an installation chamber. The crushing mechanism and the screen are arranged in the crushing chamber. The feeding port connects the crushing chamber to the outside. The driving mechanism is arranged in the installation chamber. The processing chamber is equipped with a partition that divides the inner cavity of the processing chamber into the crushing chamber and the mounting chamber. A mounting frame is fixedly installed on the side of the partition facing the mounting chamber, and the drive mechanism is fixedly installed on the mounting frame.
