Description

Technical Field

[0001] The utility model relates to the technical field of recycled plastic production, in particular to a reaction device for producing rPET. Background Art

[0002] Recycled plastics involve the recycling, cleaning, sorting and other pre-processing of waste plastics, and then re-making them into plastic raw materials through physical or chemical methods such as melt granulation and modification, and are used in textiles, food and beverage packaging, home building materials and other fields.

When the particles in the material trays are heated, the generated gas can enter the interior of the connecting pipe through the valve. Since four heating tanks are opened on one side of the placement block, the opening and closing of several valves are adjusted so that the four heating tanks can be used alternately, which is convenient for heating the particles multiple times in the later stage. However, the device still has the following problems:

Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0035] In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 7 A reaction device for producing rPET, comprising a base frame 1 and a reactor 2,

[0036] The upper end of the base frame 1 is fixedly connected to the reactor 2;

[0037] The upper end of the reactor 2 is equipped with a stirring and cleaning mechanism 3 for processing and stirring the PET particles;

[0038] The lower end of the reactor 2 is provided with a spray mechanism 4 for discharging the stirred PET reactant;

[0039] The spraying mechanism 4 includes a nozzle mode rapid change component 41 for changing the discharge form and a drive component 42 for controlling the operation of the nozzle mode rapid change component 41. The nozzle mode rapid change component 41 is installed at the discharge port at the lower end of the reactor 2, and the drive component 42 is installed in the middle of the base frame 1 and connected to the nozzle mode rapid change component 41.

[0040] In the present invention, when the rPET reaction is carried out, the PET particles enter the reactor 2 through the feed port, and then the reaction liquid is added. The stirring and cleaning mechanism 3 starts to work, and the PET particles and the reaction liquid are fully stirred while the residual reactants on the inner wall of the reactor 2 are removed. When the reaction is completed, the driving component 42 controls the nozzle mode to quickly change the component 41 to rotate, and the PET after the reaction is completed is discharged.

[0041] In the present invention, the stirring and cleaning mechanism 3 not only achieves sufficient stirring of the PET particles and the reaction liquid, thereby improving the reaction efficiency of producing rPET, but also achieves cleaning of the reactor 2 during the stirring process, thereby reducing the workload of maintenance personnel; through the cooperation of the nozzle mode rapid change component 41 and the drive component 42, a variety of spraying modes are achieved, thereby improving the discharge efficiency of the rPET reaction equipment and increasing the flexibility and practicality of the reaction equipment;

[0042] The stirring and cleaning mechanism 3 includes a motor 31, a rotating shaft 32, a bracket 33, a spiral stirring blade 34, a scraper plate 35 and a fixed plate 36. The motor 31 is fixedly mounted on the upper end of the reactor 2, and the output end of the motor 31 is fixedly connected to the rotating shaft 32. A plurality of brackets 33 are fixedly mounted on the outer end of the rotating shaft 32, and the brackets 33 are linearly and evenly arranged at equal intervals downward on the rotating shaft 32; one end of the plurality of spiral stirring blades 34 is fixedly connected to one end of one bracket 33, and the other end of the spiral stirring blades 34 is fixedly connected to one end of another bracket 33, and the spiral stirring blades 34 are linearly and evenly arranged at equal intervals downward along the direction of the rotating shaft 32; the fixed plate 36 is symmetrically fixedly connected to one end of the bracket 33, one end of the scraper plate 35 is fixedly connected to the fixed plate 36, and the other end of the scraper plate 35 is in sliding contact with the inner wall of the reactor 2;

[0043] In the present invention, when the rPET reaction is carried out, the motor 31 drives the rotating shaft 32 to rotate, and the spiral stirring blade 34 rotates with the rotating shaft 32 to fully stir the reactants in the reactor 2; during the stirring reaction process, the scraper 35 scrapes off the PET particles remaining on the inner wall of the reactor 2;

[0044] In the present invention, the spiral stirring blades 34 can achieve sufficient stirring of the reactants, thereby improving the reaction efficiency of the rPET. The scraper 35 not only scrapes off the PET particles remaining on the inside of the reactor 2 for a more complete reaction, but also reduces the probability of failure of the reaction equipment due to residue accumulation.

[0045] The nozzle mode rapid change component 41 includes a discharge disc 411, a discharge hole 412, an alignment disc 413, an alignment hole 414, a baffle 415 and a spray disc 416. The discharge disc 411 is fixedly connected to the discharge port of the reactor 2, and the discharge disc 411 is provided with a discharge hole 412; the alignment disc 413 is rotatably connected to the discharge disc 411, and the alignment disc 413 is provided with an alignment hole 414 for aligning the discharge hole 412 with the discharge hole 412. The plurality of alignment holes 414 are evenly distributed on the alignment disc 413 at equal intervals around the circumference. The alignment disc 413 is fixedly mounted on the upper end of the spray disc 416, and the baffle 415 is fixedly mounted inside the spray disc 416.

[0046] The drive assembly 42 includes a ring gear 421, a gear 422, a servo motor 423, and a support plate 424. The ring gear 421 is fixedly connected to the outer side of the spray plate 416, the support plate 424 is fixedly connected to the lower end of the base frame 1, the servo motor 423 is fixedly connected to the upper end of the support plate 424, the output end of the servo motor 423 is fixedly connected to the lower end of the gear 422, and the gear 422 is meshed with the ring gear 421;

[0047] In the utility model, the baffle 415 divides the interior of the spray disc 416 into multiple areas, and the multiple alignment holes 414 opened on the alignment disc 413 are connected to different areas. The bottom of each area is provided with spray ports of different diameters and numbers, corresponding to different spray modes. After the rPET reaction is completed, the appropriate spray mode is selected, the servo motor 423 drives the gear 422 to rotate, and the gear 422 drives the spray disc 416 to rotate through the ring gear 421. When the discharge hole 412 is aligned with the alignment hole 414 corresponding to the pre-set spray mode, the servo motor 423 stops working, and the rPET reactant can enter the designated spray mode area through the discharge hole 412 and be sprayed out through the spray disc 416.

[0048] In the present invention, by changing the alignment of the discharge hole 412 with different alignment holes 414 to change different spraying modes, the discharge efficiency of the rPET reaction equipment is improved, and the flexibility and practicality of the reaction equipment are increased.
