Description

Technical Field

[0001] The invention relates to the technical field of modified plastic recycled masterbatch granulation, in particular to a modified plastic recycled masterbatch granulation device. Background Art

[0002] During the process of waste plastics being processed into granular recycled masterbatch through a series of granulation processes such as crushing, cleaning, drying, mixing, extrusion, and pelletizing, the waste plastics are usually modified by physical, chemical or mechanical methods to improve the performance of the recycled masterbatch or give it new functions. During the granulation process of waste plastics, the crushed waste plastics usually need to be rinsed in a sinking and floating manner by water washing equipment to remove dirt on the surface of the waste plastics and to separate the floating plastics and the sinking plastics in the water washing equipment. The floating materials can usually be directly transported to the drying equipment for drying, while the sinking materials usually need to be dried after a secondary rinsing process.

[0003] In the prior art, the plastics that have sunk to the bottom of the water are generally continuously transported forward for rinsing by a spiral conveying device in a rinsing rack, and the cleaned sunk plastics are transported to a material guide cover, where the sunken materials are continuously accumulated upwards until they are squeezed out of the discharge port at the front end of the material guide cover and fall into a drying device for drying.

[0004] However, the traditional method of conveying and unloading the settled plastic has the following problems: 1. The existing method of outputting and unloading the settled plastic not only leads to a slow unloading speed and low efficiency for the overall settled material, but also the settled materials that absorb moisture will adhere to each other and block the unloading port, which not only further slows down the overall unloading speed and the overall processing progress of the waste plastic granulation, but also requires manual intermittent unblocking of the unloading port to prevent the unloading port from being completely blocked and unable to unload, thereby increasing the overall manual workload and overall labor costs; 2. In the prior art, since the surface of the settled plastic that falls into the drying equipment in the material guide cover absorbs a lot of moisture, not only does the drying efficiency of the drying equipment for the settled plastic as a whole low, the energy consumption is large, and the cost is high, but it also leads to low utilization rate of the washing water in the rinsing rack, too fast loss, and high frequency of replenishing washing water, thereby increasing the cleaning cost of the settled plastic and the overall cost of the waste plastic granulation.

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.

[0031] See also Figure 1 A modified plastic recycled masterbatch granulation device is used to convey and discharge waste plastics that have sunk to the bottom, including a rinsing rack 1, on which a conveying mechanism 2 is provided, and a guiding mechanism 3 for guiding the plastics that have sunk to the bottom is provided on the front side of the conveying mechanism 2, and a filtering mechanism 4 is provided on both the rinsing rack 1 and the guiding mechanism 3.

[0033] When the waste plastics deposited at the bottom of the washing water in the rinsing rack 1 need to be cleaned, the motor 22 drives the spiral conveying rod 23 to rotate continuously, and the spiral conveying rod 23 then cleans the waste plastics that have settled at the bottom by continuously stirring the washing water, and simultaneously spirally conveys the plastics that have settled at the bottom forward into the material guide cover 21. The cleaned waste plastics in the material guide cover 21 are then gradually accumulated upward into the drainage mechanism 3 on the front side of the material guide cover 21.

[0034] See also Figure 1 and Figure 3 The guiding mechanism 3 includes a circular guiding cover 31 fixedly arranged on the front side of the material guiding cover 21, and a lower docking part 32 is commonly provided inside the circular guiding cover 31 and on the material guiding cover 21, and an extrusion part 33 for extruding and dehydrating the bottom plastic is provided on the lower docking part 32, an opening and closing limit part 34 that cooperates with the extrusion part 33 in transmission is provided on the circular guiding cover 31, and an upper docking part 35 is provided on the front side of the circular guiding cover 31, and a positioning driving part 36 that drives the extrusion part 33 is commonly provided on the circular guiding cover 31 and the upper docking part 35.

[0036] See also Figure 3 、 Figure 4 and Figure 7 The extrusion portion 33 includes a filter plate 331 symmetrically arranged in the circular drainage cover 31. The opposite sides of the symmetrical filter plates 331 are fixedly connected to the swivel seat 1 323 and the swivel seat 2 324 respectively. A plurality of water filtering holes that pass through the upper and lower parts are evenly opened on the filter plate 331. A ball bearing is rolled on the front side of the lower surface of the filter plate 331. An extrusion plate 332 is fixedly set on the opposite side of the upper surface of the symmetrical filter plates 331. A docking socket 333 is fixedly set on the upper end of the extrusion plate 332. A socket 1 that passes through the front and rear parts is opened on the docking socket 333.

[0037] See also Figure 4 、 Figure 5 and Figure 6The opening and closing limit part 34 includes a linear slide groove 341 symmetrically opened on the lower surface of the inner part of the circular guide cover 31. The outer side of the circular guide cover 31 is fixedly provided with a cylinder 342 symmetrically fixedly provided with a support 1. The telescopic end of the cylinder 342 is fixedly provided with a wedge-shaped support block 343 that moves back and forth and slides with the corresponding linear slide groove 341 through a connecting plate 1. The front side of the wedge-shaped support block 343 is fixedly provided with an oblique limit rod 344.

[0038] When a large amount of cleaned waste plastics are accumulated in the return-shaped guide cover 31, the cylinder 342 drives the connecting plate 1 and the wedge-shaped support block 343 to move backward along the corresponding linear slide groove 341, and the inclined surface of the front end of the wedge-shaped support block 343 is pressed and engaged with the ball bearing on the lower surface of the corresponding filter plate 331 to drive the filter plate 331 to move away from one end of the lower docking shaft 321 and lift it upward to a specific height. The left and right symmetrical filter plates 331 are then synchronously rotated around the lower docking shaft 321 by the corresponding rotating seat 1 323 and rotating seat 2 324. The left and right symmetrical squeezing plates 332 are synchronously rotated and continuously squeeze and clamp the waste plastics accumulated on the opposite side until the filter plate 331 rotates to a specific angle. The cleaning water adsorbed in the squeezed waste plastics is squeezed out and falls downward into the filter mechanism 4 through the water filter holes on the filter plate 331. The cleaning water filtered by the filter mechanism 4 will flow back to replenish the rinsing rack 1 again.

[0039] The above-mentioned operation method can realize the rapid squeezing, dehydration and stable clamping of the waste plastics accumulated in the circular drainage cover 31, and the squeezed waste water can be returned to the rinsing rack 1 for multiple utilization, thereby not only improving the overall drying efficiency of the subsequent waste plastics, reducing the overall energy consumption and cost of the drying equipment, but also improving the utilization rate of the washing water in the rinsing rack 1, reducing the cleaning cost of the plastics that have settled to the bottom and the overall cost of the waste plastic granulation.

[0040] See also Figure 3 、 Figure 4 and Figure 7 The upper docking part 35 includes an L-shaped fixed platform 351 fixedly set on the front side of the circular guide cover 31, and an upper docking shaft 352 is fixedly set symmetrically on the left and right sides of the rear side of the vertical section of the L-shaped fixed platform 351. A multi-stage hydraulic cylinder 353 is fixedly set at the front end of the horizontal section of the L-shaped fixed platform 351 through a second support.

[0041] See also Figure 3 and Figure 7The positioning drive part 36 includes a connecting frame 361 that is fixedly arranged on the telescopic end of the multi-stage hydraulic cylinder 353 and is movable forward and backward. A connecting rod 362 is fixedly arranged on the lower side of the connecting frame 361 symmetrically on the left and right. A connecting plate 2 is fixedly arranged on the lower side of the connecting rod 362. A docking plug-in 363 that is fixedly arranged on the lower side of the connecting plate 2 symmetrically on the front and back and is aligned with the corresponding socket. The docking plug-in 363 is provided with a socket 2 that passes through from front to back and is aligned with the corresponding upper docking shaft 352.

[0042] When the extrusion plate 332 and the docking socket 333 rotate to a specific angle with the corresponding filter plate 331, the socket 1 on the docking socket 333 is aligned with the front-to-back symmetrical docking plug 363 on the corresponding connecting plate 2, and the multi-stage hydraulic cylinder 353 drives the connecting frame 361 to move forward, and the connecting frame 361 drives the connecting plate 2 and its corresponding docking plug 363 to move forward synchronously through the connecting rod 362, and the front docking plug 363 is aligned with the corresponding upper docking shaft 352 through the socket 2, and the rear docking plug 363 is aligned and inserted into the socket 1 in the corresponding docking socket 333, and then synchronously drives the corresponding docking socket 333 to move forward and plug into the corresponding upper docking shaft 352, and the docking socket 333 drives the extrusion plate 332 that is symmetrical on the left and right and holds the dehydrated waste plastic along the upper docking shaft 352. The filter plate 331 and the filter plate 331 move forward synchronously along the lower docking shaft 321 until the rotating seat 1 323 and the rotating seat 2 324 are completely separated from the lower docking shaft 321. At this time, the rear side of the filter plate 331 is in contact with the corresponding oblique limit rod 344. Under the guidance of the oblique limit rod 344 and the action of the gravity of the filter plate 331 and the filter plate 332, which continue to move forward, rotate around the corresponding upper docking shaft 352 through the corresponding docking socket 333 to open in reverse, and the dehydrated waste plastic clamped on the opposite side is stably put downward into the corresponding drying equipment for drying. The above operation method not only improves the overall unloading speed of the waste plastic at the bottom and the overall cleaning efficiency of the waste plastic, but also reduces the overall burden of manual work in guiding and unloading the accumulated plastic, thereby reducing the overall labor cost.

[0043] See also Figure 1 and Figure 3 The filtering mechanism 4 includes a guide portion 41 provided on the rinsing rack 1 and the return-shaped drainage cover 31 , a pipe quick-install portion 42 provided on the guide portion 41 , and a wastewater filtering portion 43 provided on the pipe quick-install portion 42 .

[0044] See also Figure 1 、 Figure 3 and Figure 8The guide part 41 includes a filter 411 installed on the lower surface of the inner part of the return-shaped guide cover 31, and a collection cover 412 connected to the inner part of the return-shaped guide cover 31 is fixedly provided on the lower side of the return-shaped guide cover 31. A bellows 413 is provided below the collection cover 412, and an L-shaped guide pipe 414 is fixedly provided on the lower side of the bellows 413. The rear end of the L-shaped guide pipe 414 is installed on the front side of the rinsing rack 1 and is connected to the inner part of the rinsing rack 1.

[0045] See also Figure 3 、 Figure 8 and Figure 9 The pipe quick-install part 42 includes a mounting ring 421 symmetrically arranged between the condenser cover 412 and the bellows 413. The symmetrical mounting rings 421 are fixedly arranged at the lower end of the condenser cover 412 and the upper end of the bellows 413 respectively. The opposite sides of the symmetrical mounting rings 421 are symmetrically provided with arc-shaped sliding grooves 422 with a T-shaped cross-section. A slot 423 is provided at one end of the arc-shaped sliding groove 422. The opposite sides of the symmetrical mounting rings 421 are fixedly provided with a sealing ring located on the inner side of the corresponding arc-shaped sliding groove 422. A threaded rod 424 is fixedly provided on the upper mounting ring 421 through a support three. A sliding seat 425 that moves up and down and is slidably connected to the corresponding threaded rod 424 is fixedly provided on the lower mounting ring 421. The threaded rod 424 is threadedly connected to a nut 426 located on the lower side of the corresponding sliding seat 425.

[0047] The waste water squeezed out by the squeezing plate 332 and the filter plate 331 after cleaning will flow downward into the confluence cover 412 through the water filter holes on the filter plate 331. The filter screen 1 411 can block the waste plastic, and the waste water flowing into the confluence cover 412 will then flow downward through the filter screen 2 432 in the filter tube 431. The filter screen 2 432 can filter the dirt remaining in the waste water, thereby re-filtering the waste water into cleaning water that meets the requirements. The cleaning water filtered by the filter screen 2 432 can finally be replenished and flow into the rinsing rack 1 through the bellows 413 and the L-shaped guide pipe 414 to clean the waste plastic.

[0048] When the filter tube 431 is to be installed between the confluence cover 412 and the bellows 413, the T-shaped slide post 433 on the upper side of the filter tube 431 is first inserted into the slot 423 at the end of the corresponding arc-shaped slide groove 422, and then the slide 425 and the lower mounting ring 421 are driven upward along the threaded rod 424 by screwing the nut 426. The bellows 413 is then stretched upward synchronously until the T-shaped slide post 433 on the lower side of the filter tube 431 is also inserted into the slot 423 at the end of the corresponding arc-shaped slide groove 422. At this time, the filter tube 431 is rotated in a specific direction (such as Figure 9 The screw 426 is then tightened to move the slide 425 and the mounting ring 421 upwards, and the T-shaped slide 433 is then further inserted into the corresponding arcuate groove 422 until the sealing ring is stably fitted and sealed with the corresponding end face of the filter tube 431. The above operation method can not only ensure the stability and sealing of the installation of the filter tube 431, but also realize the rapid disassembly and replacement of the filter tube 431.
