Description

Technical Field

[0001] The present invention relates to the technical field of PET plastic recycling, in particular to a PET plastic recycling flotation washing device and a use method thereof. Background Art

[0002] PET plastic has a wide range of applications in the packaging field. Both packaging films and coils use PET plastic. PET plastic bottles are not only used to package carbonated beverages, drinking water, juice, enzymes and tea beverages, and are the most widely used beverage packaging today, but are also widely used in many fields such as food, chemicals, and pharmaceutical packaging.

[0003] Although PET plastic is widely used in various industries, its reusability is not high and it is usually discarded after use. However, discarded PET plastic also has recycling value and can be made into products in other fields after reprocessing. When recycling PET plastic, it needs to be crushed and then float washed before it can be reprocessed. Although the existing float washing equipment can also perform simple cleaning, it still has obvious defects in actual use, such as:

[0004] After being crushed, conventional PET plastic is usually placed in a large water-filled washing tank. This tank is also equipped with a stirring rack to agitate the water to clean the fragments. However, PET plastic is less dense than water and therefore floats on the water surface. The short-term agitation by the stirring rack alone is insufficient to effectively float the PET plastic fragments. Consequently, after the fragments are retrieved, they must be transferred through multiple conveying devices to a second washing tank for a second floatation. This flotation process is time-consuming and inefficient. Furthermore, the installation and assembly of multiple washing tanks and conveying devices not only increases costs but also occupies a large amount of space, making it unsuitable for current use.

[0005] Therefore now design can improve a kind of PET plastic recycling float washing device of cleaning efficiency and quality to solve this type of defect. Summary of the Invention

The bottom end of the lifting guide rod passes through the storage frame and extends to the inner side of the storage frame.

[0015] The present invention also discloses a method for using a PET plastic recycling and flotation washing device, which specifically comprises the following steps:

[0016] S1. Before use, connect the water pipe to the water source, then use the water pump to continuously fill the inside of the float washing cylinder with water to maintain the water level. After the inside of the float washing cylinder is filled with water, it will continuously flow out from the overflow ring and fall on the inside of the ring frame. Then put the plastic into the inner side of the crushing frame and start the motor. After the motor starts, it will drive the rotating cylinder rod and the crushing blade to rotate, and the rotation of the crushing blade will crush the plastic.

[0017] S2. After the plastic is crushed by the crushing blade, it accumulates inside the storage frame. Since the threaded rod is limited by the limiting torque groove and the limiting cross bar, the threaded barrel rotates and drives the threaded rod to reciprocate and retract to the inside of the rotating barrel rod. Whenever the conical push seat separates from the feeding vertical barrel and rises to the inside of the storage frame, the crushed materials inside the storage frame fall into the inside of the feeding vertical barrel. However, since the inside of the floating washing cylinder is filled with water, the plastic fragments will float on the top of the inner cavity of the feeding vertical barrel. When the threaded rod pushes the conical push seat to continue to descend, the conical push seat enters the feeding vertical barrel and presses the fragments to the bottom of the feeding vertical barrel. After the fragments are pushed to the bottom of the feeding vertical barrel, they are scattered at the bottom of the inner cavity of the floating washing cylinder. At the bottom of the water inside the washing cylinder, when the rotating cylinder rod rotates, it will drive the driven vertical rod and the gear plate to rotate through the pulley and the belt. When the gear plate rotates, it will synchronously drive the gear ring and the gear outer ring to rotate under the guidance of the bearing ring sleeve and the U-shaped sliding frame. The rotation of the gear ring will use the vertical rotating rod to drive several stirring plates to rotate. At this time, the rotation of the stirring plates will stir the debris for cleaning. However, each time the debris is stirred, it will be blocked by the floating baffles of different heights, so as to ensure that the debris stays in the water of the floating washing cylinder for a long time. After being continuously stirred and cleaned by the stirring plates, the debris will eventually rise to the water surface, and then the cleaned debris will flow out from the overflow ring with the water and fall into the inside of the annular frame.

[0018] S3. After the debris and water fall into the inside of the annular frame, they will be driven by the water flow to flow. At the same time, the rotation of the outer ring of the gear will drive several push scrapers to scrape the inside of the annular frame. The push scrapers will push the debris inside the annular frame to the inside of the inclined guide frame. Then the inclined guide frame will make the debris flow more efficiently. When the threaded rod drives the conical push seat to rise to the inside of the storage frame, the bottom of the inner side of the limit torque groove will pull the limit cross bar to rise in the limit of the lifting guide rod and compress the spring. The lifting guide rod will use the curved frame to drive the lifting The lifting rod rises, and when it rises, it will slide at an angle at the bottom of the arched bottom plate, thereby driving the water-beaming inclined plate to rise from the lifting chute. After rising, the water-beaming inclined plates on both sides will bend water to the inside of the inclined guide frame to increase the water flow rate and wash away the debris accumulated inside the inclined guide frame. After the threaded rod drops, the spring pushes the limit cross bar to drop. At the same time, the lifting rod also drives the arched bottom plate and the water-beaming inclined plate to drop. After the water-beaming inclined plate is re-located to the inside of the lifting chute, it will no longer block the water flow and restore the unloading width. After the debris flows out from the bottom of the inclined guide frame, the cleaning is completed.

[0019] The present invention provides a PET plastic recycling flotation washing device and its use method. Compared with the existing technology, it has the following advantages:

[0020] (1) The PET plastic recycling and flotation washing device and its use method are to use a crushing and flotation washing mechanism and a material discharging and diversion mechanism in combination. The arrangement of these two mechanisms can, after the PET plastic is crushed, use a conical push seat to send the fragments as a whole to the bottom of the flotation washing cylinder. Then, under the stirring and beating of the stirring plate and the blocking of the flotation baffle, the time for the fragments to be immersed in water is prolonged, and the water can circulate and flow out from the overflow ring mouth, thereby improving the quality of cleaning. After cleaning, the water can be directly discharged from the flotation washing cylinder along with the flow of water. Compared with the traditional method of transporting by equipment such as augers and conveyor belts, it is more convenient and reduces costs. At the same time, it shortens the material transportation and secondary cleaning links, effectively improves the efficiency of recycling and flotation washing, and satisfies current use.

[0021] (2) The PET plastic recycling float washing device and its use method are as follows: a plurality of staggered anti-floating baffles of different heights are installed inside the float washing cylinder, and a stirring baffle is used between the upper and lower adjacent anti-floating baffles, and is used in combination with a conical push seat. The arrangement of these structures can first use the conical push seat to push a large amount of debris into the bottom of the float washing cylinder, and then use the multi-layer anti-floating baffles to block the debris so that the time of soaking in water can be prolonged and it cannot float to the water surface directly and quickly. In the process, the stirring baffle is used to stir and hit the debris multiple times, and push the debris to float out from the bottom of the anti-floating baffle, which can not only improve the cleaning quality, but also ensure that the debris can be blocked by the anti-floating baffle to extend the soaking time, and can also float up and discharge smoothly.

[0022] (3) The PET plastic recycling float washing device and its use method are characterized by installing an annular frame on the surface of the float washing cylinder to cooperate with the overflow ring mouth, and using it in combination with a push scraper and a water-beaming inclined plate. The arrangement of these structures can use the rotating push scraper to scrape the fragments for unloading when the fragments flow into the annular frame from the overflow ring mouth, thereby preventing the fragments from accumulating inside the annular frame and causing blockage. At the same time, the water-beaming inclined plate, which is intermittently lifted by the lifting rod, can bend water inside the inclined guide frame, thereby ensuring that some fragments stuck to the bottom can be washed away, and the flow width can be increased when descending, thereby ensuring the smoothness of unloading and saving costs.

[0023] (4) The PET plastic recycling and flotation washing device and its use method are as follows: a feeding vertical cylinder is installed at the bottom of the storage frame, and a threaded rod and a conical push seat are installed inside the rotating cylinder rod by using a threaded cylinder, and are used in conjunction with a limit torque groove and a limit cross bar. The arrangement of these structures can use the reciprocating conical push seat to push the debris inside the feeding vertical cylinder into the bottom of the flotation washing cylinder, and at the same time can avoid the clogging of the feeding vertical cylinder, improve the stability of cleaning, and when the threaded rod rises, it can use the connection with the limit cross bar to drive the lifting rod to rise and drive the water beam inclined plate, thereby effectively improving the overall practicality and functionality of the equipment and meeting the current use.

[0043] The present invention also discloses a method for using a PET plastic recycling and flotation washing device, which specifically comprises the following steps:

[0044] S1. Before use, first connect the water pipe 128 to the water source, then use the water pump to continuously fill the inside of the float washing cylinder 101 with water to maintain the water level. After the inside of the float washing cylinder 101 is filled with water, it continuously flows out from the overflow ring 129 and falls on the inner side of the annular frame 201. Then, put the plastic into the inner side of the crushing frame 103 and start the motor 105. After the motor 105 is started, it will drive the rotating cylinder rod 106 and the crushing blade 107 to rotate, and the rotation of the crushing blade 107 will crush the plastic.

[0045] When the screw rod 108 pushes the conical push seat 109 to continue to descend, the conical push seat 109 enters the feeding vertical cylinder 104 and presses the fragments to the bottom of the feeding vertical cylinder 104. After the fragments are pushed to the bottom of the feeding vertical cylinder 104, they are scattered at the bottom of the inner cavity of the floating washing cylinder 101. The bottom of the water inside the flotation drum 101 is located at the same time. When the rotating drum rod 106 rotates, it will drive the driven vertical rod 117 and the gear plate 118 to rotate through the pulley 119 and the belt 120. When the gear plate 118 rotates, it will synchronously drive the gear ring 114 and the gear outer ring 204 to rotate under the guidance of the bearing ring sleeve 113 and the U-shaped sliding frame 203. The rotation of the gear ring 114 will use the vertical rotating rod 115 to drive several stirring plates 116 to rotate. At this time, the rotation of the stirring plates 116 will stir the debris for cleaning. However, each time the debris is cleaned and stirred, it will be blocked by the anti-floating baffles 110 at different heights, thereby ensuring that the debris stays in the water of the flotation drum 101 for a long time. After being continuously stirred and cleaned by the stirring plates 116, the cleaned debris will eventually rise to the water surface, and then the cleaned debris will flow out from the overflow ring 129 along with the water and fall into the inside of the annular frame 201.

[0046] S3. After the debris and water fall into the inside of the annular frame 201, they will be driven by the water flow to flow. At the same time, the rotation of the gear outer ring 204 will drive a number of push scrapers 205 to scrape the inside of the annular frame 201. The push scrapers 205 are used to push the debris inside the annular frame 201 to the inside of the inclined guide frame 202. Then the inclined guide frame 202 flows the debris efficiently. When the threaded rod 108 drives the conical push seat 109 to rise to the inside of the storage frame 102, the bottom of the inner side of the limiting moment groove 122 will pull the limiting cross bar 126 to rise in the limit of the lifting guide rod 124 and compress the spring 125. The lifting guide rod 124 rises and drives the lifting rod 124 to rise by the curved frame 127. The lifting rod 130 rises, and when the lifting rod 130 rises, it will slide at an angle at the bottom of the arched bottom plate 208, thereby driving the water-beaming inclined plate 207 to rise from the lifting chute 206. After rising, the water-beaming inclined plates 207 on both sides will bend water to the inner side of the inclined guide frame 202 to increase the water flow rate and wash away the debris accumulated inside the inclined guide frame 202. After the threaded rod 108 drops, the spring 125 pushes the limiting cross bar 126 to drop. At the same time, the lifting rod 130 also drives the arched bottom plate 208 and the water-beaming inclined plate 207 to drop. After the water-beaming inclined plate 207 is re-located to the inner side of the lifting chute 206, it will no longer block the water flow and restore the feeding width. After the debris flows out from the bottom of the inclined guide frame 202, the cleaning is completed.

9. A method for using a PET plastic recycling and flotation washing device, characterized in that: The specific steps include: S1. Before use, first connect the water pipe (128) to the water source, then use the water pump to continuously fill the inside of the float washing cylinder (101) with water to maintain the water volume. After the inside of the float washing cylinder (101) is filled with water, the water continuously flows out from the overflow ring (129) and falls on the inside of the annular frame (201). Then, put the plastic into the inside of the crushing frame (103) and start the motor (105). After the motor (105) is started, it will drive the rotating barrel rod (106) and the crushing blade (107) to rotate, and the rotation of the crushing blade (107) will crush the plastic; S2. After the plastic is crushed by the crushing blade (107), it accumulates inside the storage frame (102). Since the threaded rod (108) is limited by the limiting torque groove (122) and the limiting cross bar (126), the threaded cylinder (121) rotates while driving the threaded rod (108) to reciprocate and shrink to the inside of the rotating cylinder rod (106). Whenever the conical push seat (109) separates from the feeding vertical cylinder (104) and rises to the inside of the storage frame (102), the crushed plastic inside the storage frame (102) is The material falls into the inside of the feeding vertical cylinder (104), but because the inside of the floating washing cylinder (101) is filled with water, the plastic fragments will float on the top of the inner cavity of the feeding vertical cylinder (104). When the threaded rod (108) pushes the conical push seat (109) to continue to descend, the conical push seat (109) enters the feeding vertical cylinder (104) and presses the fragments to the bottom of the feeding vertical cylinder (104). After the fragments are pushed to the bottom of the feeding vertical cylinder (104), they are scattered at the bottom of the inner cavity of the floating washing cylinder (101). The debris is located at the bottom of the water inside the flotation cylinder (101). At the same time, when the rotating cylinder rod (106) rotates, it drives the driven vertical rod (117) and the gear plate (118) to rotate through the pulley (119) and the belt (120). When the gear plate (118) rotates, it synchronously drives the gear ring (114) and the gear outer ring (204) to rotate under the guidance of the bearing ring sleeve (113) and the U-shaped slide frame (203). The rotation of the gear ring (114) drives the vertical rod (115) to rotate. A plurality of stirring plates (116) rotate, and the rotation of the stirring plates (116) stirs the debris for cleaning. However, each time the debris is stirred, it is blocked by the anti-floating baffles (110) at different heights, thereby ensuring that the debris stays in the water of the floating washing cylinder (101) for a long time. After being continuously stirred and cleaned by the stirring plates (116), the debris will eventually rise to the water surface, and then the cleaned debris will flow out from the overflow ring (129) along with the water and fall into the inside of the annular frame (201); S3. After the debris and water fall into the inside of the annular frame (201), they will be driven by the water flow to flow. At the same time, the rotation of the gear outer ring (204) will drive a number of push scrapers (205) to scrape the inside of the annular frame (201). The push scrapers (205) are used to push the debris inside the annular frame (201) to the inside of the inclined guide frame (202). Then, the inclined guide frame (202) makes the debris flow more efficiently. When the threaded rod (108) drives the conical push seat (109) to rise to the inside of the storage frame (102), the bottom of the inner side of the limit moment groove (122) will pull the limit cross bar (126) to rise in the limit of the lifting guide rod (124) and compress the spring (125). The lifting guide rod (124) will use the bent frame (127) to drive the lifting rod (124) to rise. The lifting rod (130) rises, and when the lifting rod (130) rises, it will slide in an inclined plane at the bottom of the arched bottom plate (208), thereby driving the water-beaming inclined plate (207) to rise from the lifting chute (206). After rising, the water-beaming inclined plates (207) on both sides beam water to the inside of the inclined guide frame (202) to increase the flow rate of water and wash away the debris accumulated inside the inclined guide frame (202). After the threaded rod (108) falls, the spring (125) pushes the limit cross bar (126) to fall, and at the same time, the lifting rod (130) also drives the arched bottom plate (208) and the water-beaming inclined plate (207) to fall. After the water-beaming inclined plate (207) is re-located inside the lifting chute (206), it no longer blocks the water flow and restores the material discharge width. After the debris flows out from the bottom of the inclined guide frame (202), the cleaning is completed.
