Usually, the crushed polyester is put into the decomposition device, and decomposition enzymes are injected into the decomposition device to accelerate the decomposition of the polyester.

[0003] Existing decomposition enzymes are usually injected into the device from the top. However, as the multiple stirring rods inside the device rotate, the decomposition enzymes injected into the device from the top may be dispersed and mixed at the top of the device, resulting in a lower concentration of the decomposition enzymes in the middle and bottom of the device. The polyester in the middle and bottom of the device is not thoroughly mixed with the reagent, which increases the time consumption for polyester decomposition and reduces the polyester decomposition efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0020] Reference Figure 1-Figure 2 A decomposition device for environmentally friendly regeneration of polyester, comprising a decomposition box 1, a rotating rod 2 is vertically rotatably installed in the decomposition box 1, a plurality of stirring rods 3 are fixedly installed on the surface of the rotating rod 2, the rotating rod 2 is controlled to rotate by a driving assembly, the driving assembly comprises a driving motor 12, a U-shaped mounting plate is fixedly installed on the top of the decomposition box 1, the driving motor 12 is fixedly installed on the upper surface of the mounting plate, and the output shaft is fixedly connected to the rotating rod 2, an enzyme storage box 4 is symmetrically fixedly installed on the surface of the decomposition box 1, and the enzyme storage box 4 is filled with decomposition enzymes;

[0021] The top, middle and bottom of the inner wall of the decomposition box 1 are symmetrically fixedly installed with a mounting shell 5, a hollow rod 6 is fixedly installed on the top wall of the mounting shell 5, a piston rod 7 is inserted in the hollow rod 6 in a sliding seal, a through hole is opened at the bottom of the mounting shell 5, the piston rod 7 is inserted in the through hole in a sliding seal, and a ball 8 is fixedly installed at the bottom, the piston rod 7 is connected to the mounting shell 5 through a telescopic component, and the telescopic component includes a telescopic spring 13 sleeved on the piston rod 7, and the two ends of the telescopic spring 13 are respectively connected to the ball 8 and the mounting shell 5 is fixedly connected, a plurality of stirring rods 3 are fixedly provided with a protruding pressing portion 9 on the upper surface, a plurality of abutting balls 8 are respectively located on the rotation paths of the plurality of protruding pressing portions 9, a hollow rod 6 is respectively connected with the decomposition box 1 and the enzyme storage box 4 through an enzyme inlet tube 10 and an enzyme outlet tube 11, a one-way valve is provided in each of the enzyme inlet tube 10 and the enzyme outlet tube 11, a conducting direction of the one-way valve in the enzyme inlet tube 10 is from the enzyme storage box 4 to the hollow rod 6, and a conducting direction of the one-way valve in the enzyme outlet tube 11 is from the hollow rod 6 to the decomposition box 1;

[0022] Start the drive motor 12. When the output shaft of the drive motor 12 rotates with the rotating rod 2 and the multiple stirring rods 3, the raised pressing parts 9 on the upper surfaces of the multiple stirring rods 3 will intermittently abut against the multiple balls 8. When the raised pressing parts 9 abut against the balls 8, under the action of the pressing, the balls 8 will move up with the piston rod 7, and the telescopic spring 13 will shrink. At this time, the volume inside the hollow rod 6 becomes smaller, and the pressure increases. The decomposition enzyme in the hollow rod 6 will be injected into the decomposition box 1 from the enzyme outlet tube 11. When the raised pressing parts 9 no longer abut against the balls 8, the pressing force exerted by the raised pressing parts 9 on the balls 8 disappears, and the balls 8 will shrink in the telescopic spring. The piston rod 7 is moved downward and reset under the elastic potential energy of the spring 13. At this time, the volume inside the hollow rod 6 increases and the pressure decreases. The decomposition enzyme in the enzyme storage box 4 will enter the hollow rod 6 from the enzyme inlet tube 10. When the ball 8 is pressed by the raised pressing part 9 next time, the decomposition enzyme in the hollow rod 6 will be injected into the decomposition box 1. Since the multiple enzyme outlet tubes 11 are respectively distributed at the top, middle and bottom of the decomposition box 1, the decomposition enzyme entering the decomposition box 1 can be thoroughly mixed with the polyester in the decomposition box 1, and there will be no uneven concentration of the decomposition enzyme in various places in the decomposition box 1. In addition, the decomposition enzyme is automatically added without manual addition, which reduces the labor burden of the staff.

[0023] At the same time, when the raised pressing portion 9 and the pressing ball 8 collide with each other, a vibration force will be generated due to the collision, and the vibration force will be transmitted to the mixed liquid in the decomposition box 1, thereby accelerating the mixing efficiency.

[0024] A disturbance component is provided on the top of the decomposition box 1, and the disturbance component is used to disturb the liquid in the decomposition box 1. The disturbance component includes two rotating shafts 14 and a plurality of disturbance plates 15 respectively fixedly mounted on the two rotating shafts 14. The two rotating shafts 14 are symmetrically and horizontally rotated and mounted on the inner wall of the decomposition box 1, and are controlled to rotate together by a transmission component. The transmission component includes a plurality of meshing bevel gears 16, and the plurality of bevel gears 16 are respectively fixedly sleeved on the rotating rod 2 and the two rotating shafts 14;

[0025] When the rotating rod 2 rotates, under the transmission action of the multiple bevel gears 16, the two rotating shafts 14 will rotate together with the multiple disturbance plates 15. Since the rotating rod 2 rotates longitudinally with the multiple stirring rods 3, and the rotating shaft 14 rotates horizontally with the multiple disturbance plates 15, the stirring direction is no longer single. Therefore, the multiple disturbance plates 15 can have a turbulent effect when rotating, thereby accelerating the mixing efficiency.

[0026] In the present invention, when the driving component controls the rotating rod 2 and the plurality of stirring rods 3 to rotate, the raised pressing parts 9 on the upper surfaces of the plurality of stirring rods 3 will intermittently abut against the plurality of abutting balls 8. When the raised pressing parts 9 abut against the abutting balls 8, under the action of abutment, the abutting balls 8 will move up with the piston rod 7, and the telescopic parts will shrink. At this time, the volume in the hollow rod 6 becomes smaller, the pressure increases, and the decomposition enzyme in the hollow rod 6 will be injected into the decomposition box 1 from the enzyme outlet tube 11. When the raised pressing parts 9 no longer abut against the abutting balls 8, the abutment force exerted by the raised pressing parts 9 on the abutting balls 8 disappears. When the piston rod 7 is lost, the ball 8 will move down and reset with the piston rod 7 under the elastic potential energy of the telescopic part. At this time, the volume inside the hollow rod 6 increases, the pressure decreases, and the decomposing enzyme located in the enzyme storage box 4 will enter the hollow rod 6 from the enzyme inlet tube 10. When the ball 8 is pressed by the raised pressing part 9 next time, the decomposing enzyme in the hollow rod 6 will be injected into the decomposition box 1. Since the multiple enzyme outlet tubes 11 are respectively distributed at the top, middle and bottom of the decomposition box 1, the decomposing enzyme entering the decomposition box 1 can be thoroughly mixed with the polyester located in the decomposition box 1, and there will be no uneven concentration of the decomposing enzyme in various places in the decomposition box 1.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
