Description

Technical Field

[0001] The utility model relates to a recovery device, in particular to a resin residual solvent recovery device, belonging to the technical field of polystyrene remodeling. Background Art

[0002] Polystyrene is a homopolymer of styrene and a general-purpose thermoplastic plastic. It does not decay, degrade or transform over time in the natural environment, and directly pollutes the environment. Therefore, the recycling and utilization of waste polystyrene raw materials has a dual meaning, that is, the waste treated purifies the environment, and renewable resources can be developed to reuse the waste;

[0003] At present, when recycling and reshaping PS foam waste products, the raw materials are first crushed and forced into the extruder with a screw propeller for extrusion and granulation to make PS recycled materials, or immersed in a high-boiling point mixed solvent to defoam and become a gel material, and then mixed with modified resins and additives, and extruded and granulated by a multi-stage extruder.

[0004] When polystyrene remodeling resin is extruded by mixing gel material and modified resin, there will be a certain amount of solvent residue on the surface of the resin. Currently, the solvent on the surface cannot be removed after production, which not only affects the quality of the verticality, but also causes a waste of solvent and increases the remodeling cost.

[0005] Therefore, a resin residual solvent recovery device is designed to optimize the above problems. Utility Model Content

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a resin residual solvent recovery device, including a recovery box 1, a centrifugal cylinder 2 is rotatably installed inside the recovery box 1, leakage holes 3 are evenly opened on the outside of the centrifugal cylinder 2, and partitions 4 are evenly and vertically arranged inside the centrifugal cylinder 2 along the circumferential direction. A bearing 5 is arranged between the outside of the centrifugal cylinder 2 and the inner wall of the recovery box 1, and a driving mechanism for controlling the rotation of the centrifugal cylinder 2 is arranged at the inner top of the recovery box 1. A blocking block 9 is provided at the bottom end of the centrifugal cylinder 2, and a lifting cylinder 10 is provided between the bottom end of the blocking block 9 and the inner bottom of the recovery box 1. A hot air mechanism for ventilating the inside of the centrifugal cylinder 2 is provided on the blocking block 9. A guide plate 17 is provided at the inner bottom of the recovery box 1, and the guide plate 17 is rotatably connected to the centrifugal cylinder 2, and the bottom end of the guide plate 17 is parallel to the bottom end of the centrifugal cylinder 2.

[0024] The overall working principle is as follows: when recycling the PS foam waste product to reshape the resin, after extrusion and granulation by the extruder, the particles are injected into the interior of the centrifugal cylinder 2. At this time, the bottom end of the centrifugal cylinder 2 is blocked by the block 9. After the centrifugal cylinder 2 is filled, the rotation of the centrifugal cylinder 2 is controlled by the driving mechanism. The resin particles are attached to the outside of the centrifugal cylinder 2 by the centrifugal force, and the solvent on the surface is discharged from the interior of the recovery box 1 through the leakage hole 3, and is guided to the outside through the guide plate 17. In addition, during centrifugal separation, the hot air mechanism is used to inject hot air into the interior of the centrifugal cylinder 2. The hot air accelerates the discharge of residual solvent and improves the recovery effect.

[0025] In this embodiment, a slope is provided on the top of the drainage plate 17, and a drainage hole is provided on the outer side of the recovery box 1 at the bottom of the slope.

[0026] Partial working principle: The setting of the top slope of the guide plate 17 can easily collect the separated solvent so as to discharge the solvent.

[0027] In this embodiment, the driving mechanism includes a motor 6, a main gear 7 and a gear ring 8. The motor 6 is installed on the inner wall of the recovery box 1. The main gear 7 is installed at the output end of the motor 6. The gear ring 8 meshing with the main gear 7 is fixed to the top of the outer side of the centrifuge cylinder 2.

[0028] Partial working principle: When controlling the centrifugal cylinder 2 to rotate, the starting motor 6 controls the main gear 7 to rotate, and the main gear 7 controls the gear ring 8 to drive the centrifugal cylinder 2 to rotate, and perform centrifugal separation operations.

[0029] In this embodiment, the hot air mechanism includes a hot air blower 11, an exhaust pipe 12 and air holes 13. The exhaust pipe 12 is vertically installed on the block 9, and the exhaust pipe 12 is located in the middle position inside the centrifugal cylinder 2. The air holes 13 are evenly opened on the outside of the exhaust pipe 12, and the hot air blower 11 is installed at the bottom end of the exhaust pipe 12.

[0030] Partial working principle: During the centrifugal separation process, the hot air blower 11 delivers hot air to the inside of the exhaust pipe 12, and the hot air is discharged horizontally to the outside through the air holes 13, thereby increasing the ventilation effect inside the resin so as to blow the solvent outward.

[0031] In this embodiment, a rubber sleeve 14 is provided between the outer side of the bottom of the blocking block 9 and the inner bottom of the recovery box 1 , and the lifting cylinder 10 and the hot air blower 11 are both located inside the rubber sleeve 14 .

[0032] Partial working principle: After the solvent is separated, the block 9 is controlled to descend, and the raw materials inside the centrifugal cylinder 2 flow downward into the inside of the recovery box 1. Due to the blocking effect of the rubber sleeve 14, the raw materials are prevented from hindering the operation of the lifting cylinder 10 and the hot air blower 11.

[0033] In this embodiment, a material guide block 15 is fixed to the inner bottom of the recovery box 1 , and a material discharge hole is opened on the recovery box 1 at the bottom of the material guide block 15 .

[0034] Partial working principle: the raw materials discharged from the inside of the centrifugal cylinder 2 are guided by the guide block 15 and discharged to the outside of the recovery box 1.

[0035] In this embodiment, a receiving hopper 16 is provided on the top of the recovery box 1 , and the bottom end of the receiving hopper 16 extends to the interior of the centrifugal cylinder 2 .

[0036] Partial working principle: When adding raw materials into the centrifugal cylinder 2, since the top of the receiving hopper 16 has a large opening, filling is more convenient.

[0037] The above is only a further embodiment 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 scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
