Description

Technical Field

[0001] The present invention relates to the technical field of PET bottle chip recycling, and specifically to a water washing device for recycling PET bottle chips and a water washing method thereof. Background Art

[0002] PET plastic bottles, used for beverage packaging, are not only widely used for packaging carbonated beverages, drinking water, fruit juices, enzymes, and tea beverages, etc., and are the most widely used beverage packaging today, but also widely used in many fields such as food, chemical, and pharmaceutical packaging. PET plastics have a wide range of applications in the packaging field. Whether it is packaging films or coils, PET plastics are used. However, when these materials are discarded, there is a problem of how to dispose of them.

[0003] Existing PET plastic bottles have great recycling value. After being crushed and recycled, they can still become raw materials for items in other fields. However, existing PET plastic bottles need to be first crushed into chips before recycling, and then the chips are washed with water. Existing water washing methods are to put the chips into a water tank and use stirring blades for cleaning. Although the cleaning work can be completed, there are still obvious defects in the process of use, such as:

[0004] PET plastic bottles are all made of PET plastics, and the density of PET plastics is smaller than that of water. Therefore, they will all float on the water surface. In existing water washing tanks, the chips are only poured into the interior, and then simply stirred with stirring blades and pushed forward until the chips move to the rear and are fished out for feeding. Since the chips have a small density and will float on the water surface, such a water washing method results in insufficient striking force of the stirring blades and inability to concentrate on cleaning the chips, so that only the relatively shallow dust on the surface of the chips can be washed off, while the relatively solid stains on the surface cannot be effectively cleaned, thereby reducing the cleaning quality and being inconvenient for subsequent recycling and processing;

[0005] Therefore, a water washing device for recycling PET bottle chips that can improve the cleaning quality is now designed to solve such defects. Summary of the Invention

[0020] The present invention provides a water washing device for recycling PET bottle chips and its water washing method. Compared with the existing technology, it has the following beneficial effects:

[0021] (1). The water washing device and method for recycling PET bottle chips can be used in a combined manner by the water washing feeding mechanism and the water filtering and discharging mechanism. The settings of these two mechanisms can place the chips inside the strong washing tank and rotate several stirring blades to carry out concentrated beating and washing, thereby removing the stains on the surface. At the same time, with the cooperation of each component, whenever the material holding mesh frame rises for discharging, the anti-floating mesh plate can be opened to release the washed chips, facilitating subsequent material fishing. At the same time, during the discharging process, the chips can be effectively jolted to filter water, improving the efficiency of the subsequent drying process and meeting the current usage requirements.

[0022] (2). The water washing device and method for recycling PET bottle chips are provided with a strong washing tank inside the water washing tank body, connected by a feeding frame and a feeding pipe, and used in combination with stirring blades. The settings of these structures can, when the staff feeds materials into the feeding pipe, use the rotating auger blades to evenly disperse the chips into the strong washing tank, and then use the rotating stirring blades to carry out high-intensity concentrated washing on them. And after the subsequent anti-floating mesh plate is opened, when the chips float upward under the guidance of the inclined plane seat, they can contact the upper layer of water and complete rinsing, ensuring the overall washing quality.

[0023] (3). The water washing device and method for recycling PET bottle chips are installed with an inclined bottom plate at the rear side inside the water washing tank body, and used in combination with the first arc block, the material holding mesh frame and the second arc block. The settings of these structures can, when the air cylinder pushes the material holding mesh frame to rise, make the second arc block continuously contact several first arc blocks, so as to vibrate up and down under the limit of the first return spring rod, shake and filter out the surface moisture, improving the efficiency of subsequent drying. At the same time, the cooperation of the lifting plate and the concave plate can ensure the stability of the material holding mesh frame during flipping and the accuracy of redocking with the U-shaped positioning plate after subsequent resetting, improving the overall practicality of the equipment.

[0024] (4). The water washing device and method for recycling PET bottle chips are installed with a pushing plate at the front end of the toothed sliding frame, and an inclined top frame cooperating with the horizontal resisting rod is installed on the surface of the pushing plate. The settings of these structures can, when the air cylinder pushes the second inclined tooth plate to rise, make the gear cylinder drive the toothed sliding frame and the pushing plate to move forward. The forward moving pushing plate makes the inclined top frame lift the anti-floating mesh plate for discharging. When the pushing plate moves backward, it can push the floating chips to the rear, facilitating the material holding mesh frame to centrally fish up the chips for discharging, improving the functionality of the equipment.

[0044] Please refer to Figure 12 、 Figure 13 and Figure 14 which shows the overall structure of the water filtering and discharging mechanism 2.

When the second helical tooth plate 216 rises, it will not abut against the tooth sliding frame 123.

[0045] The present invention also discloses a water washing method for recycling PET bottle sheet materials, which specifically includes the following steps:

[0046] S1. Preparation process: Fill the inside of the water washing tank body 101 with water, and start the motor 106 to rotate the auger blade 108 and the stirring blade 114;

[0047] S2. Central cleaning: Convey the sheet materials into the inside of the strong cleaning tank 102, and use the stirring blade 114 to strike and clean;

[0048] S3. Scooping and water filtering: Use the material scooping net frame 209 to scoop up the washed sheet materials, and shake off the water during the rising process.

[0049] The above-mentioned method for washing recycled PET bottle flakes comprises the following more specific steps:

[0050] S1. Preparation process: Before use, fill the washing tank body 101 with water in advance, and then the water will also fill the strong cleaning tank 102 through the anti-floating mesh plate 117. After the water is filled, start the motor 106. At this time, under the transmission of the pulley 110 and the belt 111, the rotating rod 107 and the two worms 109 rotate synchronously, and the rotation of the rotating rod 107 drives the auger blade 108 to rotate. At the same time, due to the meshing of the worm wheel 113 and the worm 109, a number of vertical rotating rods 112 drive the stirring blade 114 to rotate;

[0051] S2, centralized cleaning: after the preparation work is completed, the first batch of flakes are placed in the feeding pipe 103. Since the rotation of the auger blade 108 always pumps the water backwards, the put-in flakes are also transported backwards. After the flakes reach the bottom of the washing tank body 101, they float up through the feeding frame 104 and enter the powerful cleaning tank 102. However, at this time, the anti-floating mesh plate 117 is connected with the rectangular floating port 115 to be closed so that the flakes can only stay in the powerful cleaning tank 102. The rotation of several stirring blades 114 not only stirs the water flow but also hits the flakes in a centralized manner, thereby improving the cleaning quality. After the cleaning is completed, the cylinder 201 is started to push the cylinder 201. The bending plate 202 causes the bearing plate 203 as a whole to drive the material pocketing mesh frame 209 to move upward and backward, and at the same time, the second inclined tooth plate 216 drives the gear cylinder 126 to rotate counterclockwise, and the gear cylinder 126 drives the toothed sliding frame 123 and the material pushing plate 124 to move forward, and the material pocketing mesh frame 209 stops when it rises to the top, and at the same time, the inclined top frame 125 squeezes the cross bar 121 to allow the first spring 120 to drive the anti-floating mesh plate 117 to rise and separate from the rectangular floating mouth 115. At this time, the cleaned sheet material floats up under the guidance of the inclined seat 116, and contacts with the upper water during the floating process and completes the secondary cleaning. After the sheet material floats to the top, the cylinder 201 is started again to pull the material pocketing mesh frame 209 down;

[0052] S3. Pocketing and water filtering: When the pocketing mesh frame 209 descends, the second arc block 211 will drive the gear cylinder 126 to rotate clockwise, so that the gear cylinder 126 drives the tooth slide frame 123 and the pushing plate 124 to move backward. At this time, the backward movement of the pushing plate 124 will push the sheet material at the top to move backward and accumulate on the water surface. After the inclined top frame 125 separates from the horizontal rod 121, the two anti-floating net plates 117 descend under the elastic force of the first spring 120 and reconnect with the rectangular floating port 115. At this time, the sheet material is continuously input through the feeding pipe 103. After the pocketing mesh frame 209 descends into the water washing tank body 101 and then rises again, the rising of the pocketing mesh frame 209 this time will scoop up and lift the sheet material at the top of the water surface, and at the same time, the water is filtered out by the pocketing mesh frame 209. When the pocketing mesh frame 209 rises, the second arc block 211 at the bottom contacts several first arc blocks 128, and under the guiding of the first return rod 204 and the elastic action of the second spring 206, it can vibrate up and down to shake the sheet material for water filtering. When the pocketing mesh frame 209 vibrates, the U-shaped positioning plate 214 limits the side plate 208 so that it will not shake back and forth. When the second arc block 211 leaves the first arc block 128, the lifting plate 130 squeezes the concave plate 213, so that the concave plate 213 drives the U-shaped positioning plate 214 to rise and separate from the side plate 208 under the limitation of the second return rod 212. Subsequently, after the gear disk 210 meshes with the first helical tooth plate 129, the load-bearing rotating rod 207 and the entire pocketing mesh frame 209 are driven to flip by the push of the cylinder 201. When the pocketing mesh frame 209 rises to the top, at this time, the pocketing mesh frame 209 rotates 120 degrees and the opening faces downward, and then the sheet material inside the pocketing mesh frame 209 is poured out. After the sheet material is poured out, at this time, the sheet material inside the strong cleaning tank 102 is also cleaned again. Subsequently, the cylinder 201 pulls the pocketing mesh frame 209 to descend. After the pocketing mesh frame 209 rotates and resets through the first helical tooth plate 129, at this time, the lifting plate 130 separates from the concave plate 213, so that the U-shaped positioning plate 214 descends again to limit the side plate 208 until the pocketing mesh frame 209 descends to the bottom again and starts to fish for materials again.
