[0018] Compared with the prior art, the present invention provides a feeding and conveying device for semi-chemical synthesis of recycled polyester chips, which has the following beneficial effects:

[0019] 1. The present invention provides a feeding and conveying device for semi-chemical synthesis of recycled polyester chips. After the filtering mechanism separates out heavy metallic and non-metallic impurities, the remaining polyester raw material and light cotton fiber enter the filter bin through a second connecting pipe. Before the polyester raw material and cotton fiber fall into the filter bin, the sliding frame pushes the fixed block through a hydraulic rod, driving the first rotating frame to slide down to the bottom of the filter bin.

[0020] 2. The present invention sets a supporting mechanism.

[0021] 3. The present invention is provided with an auxiliary mechanism. The sliding frame pushes the fixed block with the help of a hydraulic rod, driving the first rotating frame to slide down to the bottom of the filter bin. After the polyester raw material and cotton fiber fall into the bin, the deep eutectic solvent in the filter bin begins to decompose the cotton fiber. After the cotton fiber decomposition is completed, the hydraulic rod pulls the first rotating frame to make the polyester raw material on the top of the filter screen slide toward the first separation bin, thereby improving the purity of the polyester raw material during the transportation process.

At the same time, the second auxiliary motor drives the second rotating frame through the rotating wheel, driving the auxiliary frame to rotate to improve the impurity separation efficiency. When the polyester raw material and non-metallic heavy impurities fall together, the air pump blows air to the raw material through the second guide plate, causing the heavier non-metallic heavy impurities to fall into the first connecting tube under the action of gravity, while the lighter polyester raw material and cotton fiber are blown into the second connecting tube, thereby realizing efficient separation of metal impurities and non-metallic heavy impurities in the polyester raw material.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] Example 1: See Figure 1-Figure 4The present invention provides a technical solution: a feeding and conveying device for semi-chemical synthesis of recycled polyester chips, comprising a support mechanism 1, the support mechanism 1 comprising a first support frame 101, the outer wall of the first support frame 101 is fixedly connected to a first motor 102, the output end of the first motor 102 is fixedly connected to an adjusting frame 115, the inner wall of the adjusting frame 115 is fixedly connected to a fixing frame 103, the end of the first support frame 101 away from the first motor 102 is provided with a connecting frame 107, the outer wall of the connecting frame 107 is fixedly connected to a third motor 111, the output end of the third motor 111 passes through the connecting frame 107 and is fixedly connected to a rotating rod 112, and the output end of the third motor 111 is provided with an auxiliary mechanism 2;

[0036] Auxiliary mechanism 2 includes:

[0037] The sliding frame 201 is movably connected to the outer surface of the rotating rod 112. The inner wall of the sliding frame 201 is fixedly connected to the first guide plate 202. The inner wall of the sliding frame 201 on the side close to the rotating rod 112 is fixedly connected to the hydraulic rod 203.

[0038] The fixed block 208 is fixedly connected to the output end of the hydraulic rod 203. A sliding groove 204 is provided on the outer surface of the fixed block 208. The outer surface of the fixed block 208 is fixedly connected to the first auxiliary motor 209. During the transportation of polyester raw materials, metal fragments, cotton fibers and other impurities often mixed in the raw materials need to be separated by the filtering mechanism 3. Subsequently, the first rotating frame 205 containing polyester raw materials and cotton fibers is moved to the inside of the filter chamber 108 under the push of the hydraulic rod 203. The filter screen 207 fixedly connected to the inner wall of the bottom of the first rotating frame 205 realizes solid-liquid separation during the movement. The filter chamber 108 is filled with a deep eutectic solvent, and the cellulase therein can effectively decompose the cotton fibers, thereby improving the purity of the polyester raw materials.

[0039] The inner wall of the connecting frame 107 on one side close to the third motor 111 is fixedly connected to the filter chamber 108, the inner wall of the connecting frame 107 on one side away from the filter chamber 108 is fixedly connected to the first separation chamber 109, the bottom outer wall of the first separation chamber 109 is fixedly connected to a connecting hose 110, the end of the connecting hose 110 away from the first separation chamber 109 is fixedly connected to the fixing frame 103, the interior of the filter chamber 108 is filled with a deep eutectic solvent for directionally decomposing the cotton fibers mixed in the polyester chips, the outer wall of the connecting frame 107 on one side close to the first separation chamber 109 is fixedly connected to a heating fan 114, and the outer wall of the heating fan 114 away from the connecting frame 107 is fixedly connected to the bottom outer wall of the first separation chamber 109. The second support frame 113, the second support frame 113 is provided with a filtering mechanism 3 at one end away from the connecting frame 107, and the heating fan 114 is used to dry the polyester chips. After the filtering mechanism 3 completes the separation of metal fragments in the polyester raw material, the deep eutectic solvent in the filter chamber 108 decomposes the cotton fibers, thereby effectively improving the purity of the polyester raw material. When the cotton fiber decomposition operation is completed, the hydraulic rod 203 pulls the fixed block 208 to move toward the sliding frame 201, driving the first rotating frame 205 to rise together with the processed polyester raw material. Then, the third motor 111 drives the rotating rod 112 to move the sliding frame 201 toward the first separation chamber 109.

[0040] The output end of the first auxiliary motor 209 is fixedly connected to the first rotating frame 205, and the inner wall of the first rotating frame 205 is fixedly connected to the filter screen 207. The outer wall of the first rotating frame 205 on one side close to the sliding groove 204 is rotatably connected to the auxiliary wheel 206 through a rotating shaft. The auxiliary wheel 206 is rotatably connected to the inner wall of the sliding groove 204. The sliding groove 204 is used to limit the deflection angle of the first rotating frame 205. The bottom outer wall of the fixed frame 103 is fixedly connected to the second motor 104, and the outer wall of the end of the fixed frame 103 away from the second motor 104 is fixedly connected to the discharge pipe 106. The output end of the second motor 104 is fixedly connected to the screw rod 105, which is used for conveying polyester chips. The third motor 111 drives the rotating rod 112 to drive the sliding frame 201 to move to the first separation bin 109 to move into place. Afterwards, the first auxiliary motor 209 deflects the first rotating frame 205. At the same time, the heating fan 114 sends hot air to the first guide plate 202 on the inner wall of the sliding frame 201. The hot air is gathered through the first guide plate 202 and blown to the filter screen 207 fixed on the inner wall of the first rotating frame 205 to dry the polyester raw material thereon. As the deflection angle of the first rotating frame 205 increases, the dried polyester raw material is smoothly poured into the inner wall of the first separation bin 109, and the connecting hose 110 transports the polyester raw material to the fixed frame 103. The second motor 104 pushes the raw material toward the discharge pipe 106 through the screw rod 105, and the first motor 102 flexibly adjusts the flipping angle of the fixed frame 103 so that the discharge pipe 106 can be adjusted to different heights, thereby facilitating the transportation of the polyester raw material.

[0041] Recycled polyester raw materials are often mixed with impurities such as cotton fibers. During the feeding and conveying process, these impurities will interfere with subsequent synthetic production operations, resulting in reduced product quality. To solve this problem, an auxiliary mechanism is set up. After the polyester raw material is separated from metal and non-metal heavy impurities by the filtering mechanism 3, the remaining polyester raw material and light cotton fibers will enter the filter bin 108 through the second connecting pipe 312. Before the polyester raw material and cotton fibers fall into the filter bin 108, the sliding frame 201 pushes the fixed block 208 with the help of the hydraulic rod 203, driving the first rotating frame 205 to slide down to the bottom of the filter bin 108. After the polyester raw material and cotton fibers fall into the bin, the deep eutectic solvent in the filter bin 108 begins to decompose the cotton fibers. After the cotton fibers are decomposed, the hydraulic rod 203 pulls the first rotating frame 205 to make the polyester raw material on the top of the filter screen 207 slide toward the first separation bin 109, thereby improving the purity of the polyester raw material during transportation.

[0042] Example 2: Please refer to Figure 5-Figure 8 313, and the second support frame 113 is fixedly connected to the filter mechanism 310. The filter mechanism 310 includes a second separation chamber 310, the top of the second separation chamber 310 is fixedly connected to the second support frame 113, the outer wall of the second separation chamber 310 is fixedly connected to the air pump 313, the inner wall of the second separation chamber 310 close to the air pump 313 is fixedly connected to the second guide plate 314, the bottom outer wall of the second separation chamber 310 is fixedly connected to the first connecting pipe 311, the outer wall of the second separation chamber 310 at one end away from the first connecting pipe 311 is fixedly connected to the second connecting pipe 312, and the second connecting pipe 312 is away from the second One end of the separation bin 310 is fixedly connected to the connecting frame 107. When the polyester raw material falls into the second separation bin 310 through the through hole 309 on the outer surface of the screening frame 301, it will fall together with the non-metallic heavy impurities. At this time, the air pump 313 blows air to the raw material through the second guide plate 314 to achieve blowing separation of the polyester raw material. Under the action of the airflow, the heavier non-metallic heavy impurities are affected by gravity and fall directly into the first connecting pipe 311, while the lighter polyester raw material and cotton fiber are blown into the second connecting pipe 312 by the airflow generated by the air pump 313, thereby completing the effective separation of substances of different weights.

[0043] The top outer wall of the second separation bin 310 is fixedly connected to a screening rack 301, and the outer wall of the screening rack 301 on the side away from the second separation bin 310 is fixedly connected to a second auxiliary motor 302, and the output end of the second auxiliary motor 302 is fixedly connected to a rotating wheel 303. A second rotating rack 304 is provided on the top of the screening rack 301, and a groove 305 is provided on the bottom outer wall of the second rotating rack 304. A protrusion 306 is fixedly connected to the top outer wall of the second rotating rack 304. The second auxiliary motor 302 rotates the second rotating rack 304 through the rotating wheel 303. The outer surface of the protrusion 306 is movably connected to an auxiliary rack 307, and the inner wall of the auxiliary rack 307 is fixedly connected to an electromagnetic block 308. A through hole 309 is provided on the outer surface of the auxiliary rack 307. The electromagnetic block 308 is used to separate metal impurities. When performing metal separation operations on polyester raw materials, the raw materials must first be crushed into a uniform particle size of 2-5 mm. Subsequently, the polyester raw materials containing impurities are poured into the auxiliary frame 307 from the top opening thereof, and the metal impurities are adsorbed and separated by the electromagnetic block 308. At the same time, the second auxiliary motor 302 drives the second rotating frame 304 through the rotating wheel 303, driving the auxiliary frame 307 to rotate to improve the impurity separation efficiency. The separated non-metallic heavy impurities and polyester raw materials will fall into the screening frame 301 through the through hole 309 on the auxiliary frame 307. When the metal impurities in the auxiliary frame 307 need to be recovered, the auxiliary frame 307 only needs to be pulled out upwards to separate it from the second rotating frame 304, and the power supply of the electromagnetic block 308 is disconnected. The metal impurities adsorbed on the electromagnetic block 308 can then be recovered and processed.

[0044] Metal impurities are often mixed in recycled polyester raw materials. These impurities can easily have an adverse effect on subsequent synthetic production operations during the feeding and conveying process, resulting in a decline in product quality. In addition, the metal impurities in the raw materials are difficult to be effectively recovered. To solve this problem, a filtering mechanism 3 is provided. After the polyester raw material is poured into the auxiliary frame 307, the electromagnetic block 308 separates the metal impurities. At the same time, the second auxiliary motor 302 drives the second rotating frame 304 through the rotating wheel 303, driving the auxiliary frame 307 to rotate to improve the impurity separation efficiency. When the polyester raw material and non-metallic heavy impurities fall together, the air pump 313 blows the raw material through the second guide plate 314, so that the heavier non-metallic heavy impurities fall into the first connecting pipe 311 under the action of gravity, and the lighter polyester raw material and cotton fiber are blown into the second connecting pipe 312, thereby realizing the effective separation of metal impurities and non-metallic heavy impurities in the polyester raw material.
