[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In China, the treatment of landfill leachate is basically to recycle it and then add various chemical reagents to react and purify it, so as to obtain a liquid that can be discharged. Therefore, there is no technology in China to solidify and backfill the leachate.

[0022] See also Figures 1 to 4 In an embodiment of the present invention, a landfill leachate solidification and re-injection device includes a support box 1, a seal, a top cutting structure, a power piece and an intermediate linkage structure. In this embodiment, the present application uses a filling pipe 2 to realize filling after the leachate is processed and solidified, wherein the filling pipe 2 is a high-pressure pipe. After a certain curing agent is added to the leachate, it is fully stirred by a stirring structure. When it has not yet solidified, a high-pressure pump is used to input it from the high-pressure pipe into the support box 1 for solidification. Therefore, a filling pipe 2 is provided on the side of the support box 1. When the leachate solidifies inside the support box 1, it will adhere to the inside of the support box 1, including the bottom and side walls of the support box 1. Therefore, a seal is provided to slide inside the support box 1. Therefore, through the longitudinal movement of the seal, it can be used to seal the bottom of the support box 1 and the support box 1. The solidified material is lifted up, thereby lifting up the leachate solidified material adhered to the inside of the supporting box body 1. In order to further process the leachate solidified material, a top cutting structure is provided. A top plate 3 is fixed on the top of the supporting box body 1, and a top cutting structure is provided on the top plate 3, so that the leachate solidified material can be fully cut by the top cutting structure, thereby facilitating transportation and landfilling; in order to realize the longitudinal movement of the seal and the longitudinal movement of the top cutting structure, a power part is provided, and the power part is provided inside the power box 8, and the power box 8 is fixed to the bottom of the supporting box body 1, and is used to drive the movement of the seal and the top cutting structure; in this embodiment, in order to enable the top cutting structure to move downward for cutting when the sealing plate moves upward, an intermediate linkage structure is provided, which is provided on the power part, and is used to link the seal and the top cutting structure. In this embodiment, the filling pipe 2 is used to pressurize the liquid into the support box 1 and solidify it inside the support box 1. Since the volume of the support box 1 is large, the height of the leachate solid is low. Therefore, after the leachate is fully solidified, the intermediate linkage structure is used to drive the power part to move, so that when the sealing part moves upward, the top cutting structure is driven to move downward, so that when it is pushed up, the leachate solid can be prevented from adhering to the inside of the support box 1, and at the same time, it is cut by the top cutting structure, which facilitates the transportation of the leachate solid after cutting.

[0023] As a further example of this application, please refer to Figure 1 and Figure 2The bottom of the supporting box 1 is fixed with a fixed connecting rod 7, and the bottom of the supporting box 1 is fixed with a fixed connecting rod 7. The fixing connecting rod 7 fixes all the bottom supporting rods on a cross bar, and the fixing supporting rod 7 is slidably connected to the power box 8. The fixing connecting rod 7 is fixed with a connecting rod 25 at the bottom of the supporting box 1. The fixing connecting rod 7 is slidably connected to the power box 8, and the fixing connecting rod 7 is fixed with a connecting rod 25 at the bottom. The connecting rod 25 is driven by the power part, so that the longitudinal movement of the connecting rod 25 can be achieved under the driving action of the power part. In this embodiment, the power member is used to drive the fixed connecting rod 7 to move longitudinally, thereby driving the sealing plate 6 to move longitudinally, thereby lifting the solidified material inside the supporting box 1, making it easier to handle the solidified material.

[0024] As a further example of this application, please refer to Figure 1 and Figure 3 In order to ensure that the solidified material can be fully transported, the top cutting structure includes a side slider 26, a cutter 27, and a cutter support frame 5. A power member is used to provide the power for cutting, so a cutter support frame 5 is provided at the output end of the power member. This allows the power member to drive the cutter support frame 5 to move longitudinally, thereby driving the longitudinal sliding of the side slider 26 fixed to the side of the cutter support frame 5. The side slider 26 is slidably connected to the side of the support box 1, allowing the side slider 26 to slide under the limiting action of the support box 1. A cutter 27 is provided at the bottom of the cutter support frame 5. In this embodiment, the power member is used to drive the cutter support frame 5 to move longitudinally, so that the side slider 26 slides along the side of the support box 1, thereby driving the cutter 27 to slide and cut the solidified material.

[0025] As a further example of this application, please refer to Figure 1 and Figure 2 The power element includes sealing power and cutting power, enabling the sealing power to drive the connecting rod 25 to move longitudinally, while simultaneously driving the cutting power to drive the cutter support frame 5 to move longitudinally. To achieve the simultaneous action of the two, the sealing power and cutting power are connected to the ends of the intermediate linkage structure, respectively, so that the intermediate linkage structure can drive the sealing power and cutting power to operate. In this embodiment, the intermediate linkage structure drives the sealing power and cutting power to act simultaneously, enabling the solidified material to be lifted and cut.

[0026] As a further example of this application, please refer to Figure 1 and Figure 2 In order to ensure the simultaneous action of cutting power and sealing power, the intermediate linkage structure includes a drive motor 15, a driven shaft 14, an active roller 13, a driven roller 23, a driven shaft 24 and a conveyor belt. The drive motor 15 is fixed at a fixed position. The drive motor 15 is fixed at a fixed position inside the power box 8 so that the drive motor 15 drives the driven shaft 14 to rotate. Therefore, the drive motor 15 drives the connected driven shaft 14. Therefore, the sealing power is set on the driven shaft 14. In order to further realize the effect of cutting power, Therefore, a driving roller 13 is fixed to the driving shaft 14, and a driven shaft 24 is rotatably mounted at a fixed location, wherein the fixed location is set on the side wall of the power box 8. A driven roller 23 is fixed to the driven shaft 24. A conveyor belt is set between the driving roller 13 and the driven roller 23, so that the driven roller 23 can be driven to rotate under the rotation of the driving roller 13. Therefore, the function of the conveyor belt is to realize the rotation of the driven roller 23 under the action of the driving roller 13. The end of the driving shaft 14 is provided with a sealing power, and the end of the driven shaft 24 is provided with a cutting power. In this embodiment, the driving motor 15 drives the driving shaft 14, so that the driving shaft 14 drives the driving roller 13 to move, and at the same time drives the sealing power, so that under the action of the conveyor belt, the driven roller 23 is driven to rotate, so that the driven shaft 24 is rotated, and the cutting power is driven to act, so that cutting can be performed.

[0027] As a further example of this application, please refer to Figure 1 and Figure 2 In order to realize the longitudinal movement of the sealing plate 6, the sealing power includes a sliding rod 12, a connecting shell 11, a sliding groove 10 and an end fixing seat 9. First, the end of the driving shaft 14 is fixed with the end fixing seat 9, and the sliding rod 12 is fixed on the end fixing seat 9, wherein the sliding rod 12 rotates around the driving shaft 14, and a connecting shell 11 is fixed at the bottom of the sealing member. A sliding groove 10 is provided on the connecting shell 11. The connecting shell 11 is semicircular, so the sliding groove 10 is also semicircular. When the end of the sliding rod 12 and the sliding groove 10 are slidably connected, the sliding rod 12 slides inside the sliding groove 10 with the movement of the driving shaft 14, thereby realizing periodic lifting of the connecting rod 25, thereby realizing longitudinal vibration, making it less likely that the solidified material will adhere to the inner wall of the supporting box 1.

[0028] As a further example of this application, please refer to Figure 1 、 Figure 2 and Figure 3In order to make the cutter 27 cut normally, the cutting power includes a connecting piece 22, a sliding block 20, a screw 19, a pushing seat 16, a hydraulic cylinder 18, a connecting pipe 17 and a cutting hydraulic cylinder 4. First, lateral movement must be achieved to squeeze the oil pressure inside the hydraulic cylinder 18. Therefore, a screw 19 is fixed to the side of the driven shaft 24 through a connecting piece 22, so that the screw 19 can be driven to rotate when the driven shaft 24 rotates. The other end of the screw 19 is rotatably mounted on the side wall of the power box 8, wherein a fixed sleeve 21 is threadedly provided on the screw 19, and a sliding block 20 is fixed to the side of the fixed sleeve 21. The sliding block 20 is to achieve the purpose of fixing the fixed sleeve 21. The fixed sleeve 21 is used for limitation, so the sliding block 20 and the power box 8 are slidably connected, wherein a pushing seat 16 is fixed on the other side of the sliding block 20, and the input end of the hydraulic cylinder 18 is fixed on the side of the pushing seat 16, so that when the screw 19 rotates, the fixed sleeve 21 moves laterally, so that the hydraulic cylinder 18 is squeezed, so that the oil pressure inside the hydraulic cylinder 18 flows, so that the bottom of the hydraulic cylinder 18 is connected to the input end of the cutting hydraulic cylinder 4 through the connecting pipe 17, and the output end of the cutting hydraulic cylinder 4 is provided with a top cutting structure, so that the oil pressure enters the connecting pipe 17 and finally reaches the inside of the cutting hydraulic cylinder 4, and the cutter support frame 5 is moved longitudinally to achieve cutting.

[0029] As a further example of this application, please refer to Figure 1 and Figure 4 In order to realize the unloading of the solidified material, a discharge plate 30 is rotatably provided on the side of the supporting box body 1 through a hinge seat 28, so that the discharge plate 30 can be rotated. The discharge plate 30 is driven by a power motor, that is, the power motor drives the discharge plate 30 to rotate, and a sealing film 29 is fixed on the side wall of the discharge plate 30, and the end of the sealing film 29 is connected to the bottom of the supporting box body 1. The sealing film 29 has a certain space, so that when the discharge plate 30 is erected, it can block the leachate, and when the discharge plate 30 is rotated, the sealing film 29 will not be damaged.

[0030] The working principle of the present invention is: the filling pipe 2 is used to press the liquid into the support box 1, and solidify it inside the support box 1. Since the volume of the support box 1 is large, the height of the leachate solid is low. Therefore, after the leachate is fully solidified, the driving motor 15 is used to drive the driving shaft 14, so that the driving shaft 14 drives the active roller 13 to move, and at the same time drives the sealing power, so that under the action of the conveyor belt, the driven roller 23 is driven to rotate, and the driven shaft 24 is rotated, so that when the seal moves upward, the top cutting structure is driven to move downward, so that when it is pushed up, the leachate solid can be prevented from adhering to the inside of the support box 1, and at the same time, it is cut by the top cutting structure, which is convenient for cutting the leachate solid for transportation.
