Residue Cleaning and Packaging Platform for Nylon Purification and Recycling Section

Abstract

This utility model provides a residue cleaning and packaging platform for nylon purification and recycling processes, including a residue tilting platform, a pouring platform, and packaging bags. The residue tilting platform also includes a tilting frame, with a residue box hinged to the tilting frame. The tilting frame is equipped with a release hook to limit the movement of the residue box. A lifting mechanism is provided above the pouring platform, configured to lift the residue tilting platform above the pouring platform. When the residue tilting platform is above the pouring opening, the release hook disengages, allowing the residue box to pour the residue through the pouring opening into the packaging bag. The entire process can be completed by one person remotely, completely eliminating the labor intensity of manually lifting 50kg heavy objects and repeatedly striking them. The entire pouring operation is carried out in the platform area, with the residue falling directly into the ton bag below through the pouring opening, effectively isolating the risk of high-temperature material splashing and avoiding burn accidents. At the same time, it prevents residue debris and moisture-absorbing oil film from polluting the ground, eliminating the risk of personnel slipping at the source.

Description

Technical Field

[0001] This utility model relates to the field of tire cord fabric production technology, and more specifically to a residue cleaning and packaging platform for the nylon purification and recycling process. Background Technology

[0002] Nylon chips are melt-spun into high-strength, high-modulus nylon cord. The cord serves as the warp yarn, and the medium-fine count single yarn as the weft yarn, weaving it into tire cord fabric on heavy-duty looms. Therefore, nylon chips are an important raw material for tire cord fabric. After the polymerization reaction, the resulting melt (polymer) needs to be extruded, cooled, and pelletized to produce plastic chips. During this process, some unreacted monomers remain in the polymer melt or volatilize. Factories establish a "monomer recovery section" to extract these unreacted caprolactam monomers and return them to the upstream polymerization process for reuse. The most common and core recovery method is distillation purification. The residue is precisely the residual material left over from the distillation purification process that cannot be gasified and recovered.

[0003] The current residue handling process presents significant safety risks and immense labor intensity: operators must manually lift approximately 50kg boxes of solidified residue to a height and then slam them upside down to the ground, relying on the impact to dislodge the residue. This process is not only highly susceptible to injury due to handle slippage, but also significantly increases the risk of slipping as the residue absorbs moisture and forms an oil film on the ground during the rainy season. Furthermore, uneven cooling of the residue in summer, with the surface solidifying while the center remains hot, can easily cause scalding from hot material splashing during dumping. In addition, the dislodged residue blocks still require manual handling and bagging, resulting in extremely high labor intensity. Moreover, a large amount of water and electricity is needed for ground washing after processing, and the generated wastewater requires additional treatment. Overall, the process is inefficient and poses significant safety hazards. Utility Model Content

[0023] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0024] like Figures 1-3 As shown, this utility model provides a residue cleaning and packaging platform for a nylon purification and recycling section. The platform mainly includes a residue turning table 10, a tilting platform 20, a packaging bag 30, and a lifting mechanism.

[0025] The residue turning table 10 includes a residue box 11 for holding residue and a turning frame 12. The residue box 11 is a rectangular box with an opening at the top. The turning frame 12 consists of two symmetrical frames arranged on the outside of the residue box 11. The residue box 11 and the turning frame 12 are made of stainless steel to ensure structural strength and stability.

[0026] Furthermore, a flipping shaft 13 is fixedly provided on the inner bottom of the flipping frame 12, and the residue box 11 is hinged to the flipping shaft 13. The flipping shaft 13 is located at a non-central position at the bottom of the residue box 11. In this way, the center of gravity of the residue box 11 shifts to one side. When the residue box 11 is unrestricted, the residue box 11 can flip downward around the flipping shaft 13 to pour out the residue inside the residue box 11.

[0027] Furthermore, in order to control the flipping of the residue box 11, the flipping frame 12 is provided with a release device 121 to limit the position of the residue box 11, and the outer wall of the residue box 11 is provided with a limiting shaft 111 that cooperates with the release device 121. Through the locking cooperation of the release device 121 and the limiting shaft 111, the residue box 11 is fixed to the inner side of the flipping frame 12.

[0028] The residue box 11 has a first position and a second position on the flipping frame 12. When the residue box 11 is in the first position, the hook release device 121 and the limiting shaft 111 are locked, and the opening of the residue box 11 faces upward. When the residue box 11 is in the second position, the hook release device 121 and the limiting shaft 111 are unlocked, and the opening of the residue box 11 faces downward. In this way, the residue box 11 can be flipped and the residue inside can be poured out as needed on the flipping frame 12.

[0029] The device also includes a tilting platform 20, on which a tilting port 200 is provided. The packaging bag 30 is positioned below the tilting platform 20 in a set state, and the opening of the packaging bag 30 is located below the tilting port 200.

[0030] like Figure 2 and Figure 3As shown, a lifting mechanism is provided above the dumping platform 20. The lifting mechanism is configured to lift the residue turning table 10 above the dumping platform 20. When the residue turning table 10 is above the dumping port 200, the unhooking device 121 is unhooked, allowing the residue box 11 to dump the residue through the dumping port 200 into the packaging bag 30. The lifting mechanism is operated manually by remote control.

[0031] In this way, the entire process can be completed remotely by only one person, completely eliminating the labor intensity of manually lifting 50kg heavy objects and repeatedly striking them. The entire dumping operation is carried out in the platform area, with the residue falling directly into the 30-ton packaging bag below through the 200mm dumping port. This effectively isolates the risk of hot material splashing, avoiding burns, and also prevents residue debris and moisture-absorbing oil film from contaminating the ground, eliminating the risk of slipping at the source. Even if the residue is not completely solidified in summer, automated dumping and packaging can still be completed safely without close contact by personnel. In addition, the dry collection method significantly reduces the cost of ground washing water and wastewater treatment, achieving clean production and inherent safety.

[0032] Furthermore, during the dumping of residue, in order to ensure that the residue at the dumping port 200 falls orderly downwards into the packaging bag 30 (ton bag), a discharge cone 21 is provided on the dumping platform 20 corresponding to the dumping port 200. The discharge cone 21 is set downwards to facilitate guiding the residue into the packaging bag 30 (ton bag).

[0033] Furthermore, the bottom of the tilting platform 20 is provided with hooks 22 on the outside of the feeding cone 21, and the top of the packaging bag 30 is fixed with a hanging rope 31. The hanging rope 31 is suspended on the hooks 22. Generally, there are four hooks 22 and four corresponding hanging ropes 31. Each hanging rope 31 can be suspended on the corresponding hook 22 to keep the packaging bag 30 stable in the receiving state.

[0034] In some embodiments, in order to facilitate the removal of the full packaging bag 30 (ton bag), the bottom of the packaging bag 30 is provided with a support pallet 40, so that the bottom of the packaging bag 30 is supported by the support pallet 40. The support pallet 40 can support the packaging bag 30 (ton bag) and avoid damage to the packaging bag 30 (ton bag) due to the large impact force when the residue is dumped. It also facilitates the subsequent transportation and transfer of the packaging bag 30 (ton bag) in conjunction with a forklift.

[0035] Furthermore, the lifting mechanism includes a lifter 50 and a transverse support 60. The lifter 50 is fixedly mounted on the transverse support 60. The lifter 50 is configured to adjust the height of the residue tilting table 10 in the vertical direction, and the transverse support 60 is configured to adjust the position of the residue tilting table 10 in the horizontal direction.

[0036] The transverse support 60 includes a crossbar 61, a rotating shaft 62, and a driver 63. The rotating shaft 62 is fixed above the tilting platform 20, and the axis of the rotating shaft 62 is perpendicular to the tilting platform 20. The first end of the crossbar 61 is rotatably mounted on the outside of the rotating shaft 62, and the second end is connected to the lifter 50. The driver 63 is located on the side of the rotating shaft 62 and is configured to drive the crossbar 61 to rotate around the rotating shaft 62. The driver 63 can be a remotely controlled servo motor. The servo motor has high precision and can control the hovering position of the lifter 50.

[0037] Furthermore, the lifting device 50 includes an electric hoist 51 and a wire reel 52. The electric hoist 51 is fixed to the second end of the crossbar 61. The output end of the electric hoist 51 is fixedly connected to the wire reel 52. The height of the residue turning platform 10 is adjusted by winding and unwinding the wire reel 52. One end of the wire rope on the wire reel 52 is wound on the wire reel 52, and the other end is connected to a hook and can be hooked on the upper end of the turning frame 12. The height of the turning frame 12 is controlled by controlling the winding or unwinding of the wire reel 52 by the forward and reverse rotation of the electric hoist 51.

[0038] During operation, after the residue in the residue box 11 has cooled down and needs to be emptied, the operator holds a remote control and first controls the lifting device 50 to raise the residue tilting platform 10 to a height above the pouring platform 20. Then, the position of the horizontal moving bracket 60 is adjusted so that the residue tilting platform 10 moves horizontally to directly above the pouring port 200. Then, the unhooking device 121 is controlled to unhook, so that the residue box 11 pours the residue through the pouring port 200 into the packaging bag 30. During the pouring process, the impact force of the pouring residue box 11 is used to separate the residue from the residue box 11 and fall into the packaging bag 30. After pouring two or three times, the packaging bag 30 is full, and the forklift can lift the pallet 40 to transfer the packaging bag 30.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
