Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling and processing equipment, in particular to a plastic bottom sediment recycling and processing system. Background Art

[0002] In the recycling of waste plastics, it is usually necessary to clean the crushed waste plastics through a cleaning mechanism. The cleaned plastics will float on the cleaning liquid due to their light weight, while impurities with a density greater than the cleaning liquid will settle at the bottom of the cleaning mechanism to form sediment. However, in the actual production cleaning process, some plastics with a density slightly greater than the cleaning liquid will be mixed in the sediment. If the plastics in the sediment are not recycled, it is impossible to maximize the benefits of the waste plastic recycling resources, resulting in a lot of waste. In conventional plastic sediment recycling and processing systems, the equipment used in each process is usually arranged horizontally in sequence, so the equipment occupies a large area and has a low space utilization rate.

[0032] See also Figure 1 to Figure 2 The preferred embodiment of the utility model provides a plastic bottom material recovery and processing system, which includes a feeding mechanism 100 for conveying plastic, a cleaning mechanism 200 for cleaning plastic, a solid-liquid separation mechanism 300 for separating plastic and cleaning liquid, and a solid-solid separation mechanism 400 for separating plastic and impurities, which are arranged in sequence along the processing process direction.

[0033] The feeding mechanism 100 is arranged in an inclined manner, and is provided with a first feeding end 101 and a first discharging end 102 , wherein the first discharging end 102 is higher than the first feeding end 101 .

[0034] The cleaning mechanism 200 is arranged vertically and is provided with a second feed end 201 and a second discharge end 202 . The second feed end 201 is arranged at the top of the cleaning mechanism 200 and connected to the first discharge end 102 .

[0036] The solid-solid separation mechanism 400 is arranged vertically, and is provided with a fourth feed end 401, an impurity discharge end 402 and a plastic discharge end 403. The fourth feed end 401 and the impurity discharge end 402 are both arranged at the top of the solid-solid separation mechanism 400, the fourth feed end 401 is connected to the third discharge end 302, and the plastic discharge end 403 is arranged at the bottom of the solid-solid separation mechanism 400.

[0037] According to the plastic bottom material recovery and processing system of the utility model, when working, first, the crushed waste plastic is transported to the cleaning mechanism 200 through the feeding mechanism 100; then, the cleaning mechanism 200 uses the cleaning liquid to clean the waste plastic, and the cleaning liquid and the waste plastic are output from the cleaning mechanism 200 to the solid-liquid separation mechanism 300 together; then, the solid-liquid separation mechanism 300 performs solid-liquid separation on the waste plastic, and the waste plastic is transported from the solid-liquid separation mechanism 300 to the solid-solid separation mechanism, and the cleaning liquid flows out from the discharge port 303 arranged at the bottom of the solid-liquid separation mechanism 300; finally, the solid-solid separation mechanism 400 separates the waste plastic and impurities, and the waste plastic is discharged from the plastic discharge end 403, and the impurities are discharged from the impurity discharge end 402, thereby realizing the recovery and processing of the waste plastic bottom material, thereby avoiding a large amount of waste due to mixing with the cleaning liquid. In addition, since the feeding mechanism 100 is arranged at an angle, the cleaning mechanism 200, the solid-liquid separation mechanism 300 and the solid-solid separation mechanism 400 are all arranged vertically. Compared with the prior art where the equipment used in each process is usually arranged horizontally in sequence, the equipment occupies a smaller area and can improve space utilization.

[0038] Exemplarily, the structure of the feeding mechanism 100 is specifically as follows: the feeding mechanism 100 is a first screw feeder, which includes a first conveying cylinder 103, a first screw shaft 104, a first spiral blade 105, a first drive motor 106, a first transmission assembly 107 and a first hopper 108; the first conveying cylinder 103 is arranged inclined, the first feed end 101 is arranged at the bottom of the first conveying cylinder 103, the first discharge end 102 is arranged at the top of the first conveying cylinder 103, and the first hopper 108 is connected to the first feed end 101; the first screw shaft 104 is rotatably connected to the inside of the first conveying cylinder 103, the first spiral blade 105 is fixedly connected to the first screw shaft 104, the first drive motor 106 is fixedly installed on the first conveying cylinder 103, and the power output end of the first drive motor 106 is connected to the first screw shaft 104 through the first transmission assembly 107, and can drive the first screw shaft 104 to rotate. Thus, the crushed waste plastic is fed into the first feeding hopper 108 and enters the first conveying cylinder 103 from the first feeding end 101. The first driving motor 106 and the first transmission assembly 107 drive the first screw shaft 104 to rotate, and the first screw shaft 104 drives the first spiral blade 105 to rotate, so that the crushed waste plastic is transported in the first conveying cylinder 103 and finally falls into the cleaning mechanism 200 from the first discharging end 102 for cleaning.

[0039] Exemplarily, the structure of the cleaning mechanism 200 is as follows: the cleaning mechanism 200 includes a cleaning cylinder 203, a stirring blade 204, a second drive motor 205 and a second transmission assembly 206, the cleaning cylinder 203 is arranged vertically, the second feed end 201 is arranged at the top of the cleaning cylinder 203, and the second discharge end 202 is arranged at the bottom of the cleaning cylinder; the stirring blade 204 is rotatably connected to the inside of the cleaning cylinder 203, and the power output end of the second drive motor 205 is connected to the stirring blade 204 through the second transmission assembly 206, and can drive the stirring blade 204 to rotate. Thus, by adding cleaning liquid to the cleaning cylinder 203, and under the stirring action of the stirring blade 204, the cleaning liquid can be brought into contact with the waste plastic, thereby better cleaning the waste plastic. Further, the top of the cleaning cylinder 203 is openably connected to a cover 207, and the cover 207 is provided with a first exhaust port 208. In such a design, since air will be mixed into the cleaning liquid to form bubbles during cleaning and stirring, the provision of the first exhaust port 208 can facilitate the exhaust of air and avoid affecting the uniformity of cleaning the surface of the waste plastics, thereby improving the cleaning effect of the waste plastics.

[0040] Exemplarily, the structure of the solid-liquid separation mechanism 300 is specifically as follows: the solid-liquid separation mechanism 300 includes a dehydration cylinder 304, a second spiral shaft 305, a second spiral blade 306 and a third drive motor 307; the dehydration cylinder 304 is arranged vertically, the third feed end 301 is arranged on the bottom side wall of the dehydration cylinder 304, the third discharge end 302 is arranged on the top side wall of the dehydration cylinder 304, and the drain port 303 is arranged at the bottom of the dehydration cylinder 304; the second spiral shaft 305 is rotatably connected to the inside of the dehydration cylinder 304, the second spiral blade 306 is fixedly connected to the second spiral shaft 305, and a plurality of drainage holes 308 are evenly distributed on the second spiral blade 306; the third drive motor 307 is fixedly installed on the dehydration cylinder 304, the power output end of the third drive motor 307 is connected to the second spiral shaft 305, and can drive the second spiral shaft 305 to rotate. Thus, the waste plastic after cleaning is output from the second discharge end 202 of the cleaning mechanism 200, and enters the dewatering cylinder 304 through the third feed end 301, and the third drive motor 307 drives the second spiral shaft 305 to rotate, and the second spiral shaft 305 drives the second spiral blade 306 to rotate, so that the waste plastic rises and is finally output from the third discharge end 302; at the same time, since a plurality of drainage holes 308 are evenly distributed on the second spiral blade 306, during the rising process of the waste plastic, the cleaning liquid on the surface of the waste plastic can be drained from the drainage holes 308 and discharged through the drain port 303, thereby achieving the effect of solid-liquid separation. Furthermore, a heating wire 309 is embedded in the side wall of the dehydration cylinder 304, which can heat the waste plastic, thereby accelerating the evaporation efficiency of the cleaning liquid remaining on the surface of the waste plastic and improving work efficiency; a second exhaust port 310 is provided on the top of the dehydration cylinder 304, which can discharge the gas in the dehydration cylinder 304 in time to avoid excessive pressure in the dehydration cylinder 304.

[0041] Exemplarily, during operation, in order to improve the connection effect between the cleaning mechanism 200 and the solid-liquid separation mechanism 300 and ensure the orderliness of each process, a second screw feeder 500 is provided between the cleaning mechanism 200 and the solid-liquid separation mechanism 300, and the second screw feeder 500 includes a second conveying cylinder 501, a third screw shaft 502, a third spiral blade 503, a fourth drive motor 504, a third transmission assembly 505 and a second feeding hopper 506; the second conveying cylinder 501 is horizontally arranged, and a fifth feeding end and a fourth discharging end are provided on the second conveying cylinder 501, and the third screw feeder 500 includes a second conveying cylinder 501, a third screw shaft 502, a third spiral blade 503, a fourth drive motor 504, a third transmission assembly 505 and a second feeding hopper 506; the second conveying cylinder 501 is horizontally arranged, and a fifth feeding end and a fourth discharging end are provided on the second conveying cylinder 501. The second feeding hopper 506 is connected to the fifth feed end and to the second discharge end 202, and the fourth discharge end is connected to the third feed end 301; the third spiral shaft 502 is rotatably connected to the inside of the second conveying cylinder 501, and the third spiral blade 503 is fixedly connected to the third spiral shaft 502, and the fourth driving motor 504 is fixedly installed on the second conveying cylinder 501, and the power output end of the fourth driving motor 504 is connected to the third spiral shaft 502 through the third transmission assembly 505, and can drive the third spiral shaft 502 to rotate. Thus, the waste plastic after cleaning is output from the second discharge end 202 of the cleaning mechanism 200, and after being fed into the second feeding hopper 506, enters the second conveying cylinder 501 from the fifth feed end. The fourth drive motor 504 and the third transmission assembly 505 drive the third screw shaft 502 to rotate, and the third screw shaft 502 drives the third spiral blade 503 to rotate, so that the waste plastic is transported in the second conveying cylinder 501, and finally, after being output from the fourth discharge end, it enters the dehydration cylinder 304 through the third feed end 301 for solid-liquid separation treatment.

[0042] Exemplarily, the solid-solid separation mechanism 400 is a wind separator, and the impurity discharge end 402 is connected to the impurity collection box 405 through a connecting pipe 404. It should be noted that since waste plastics are mixed with impurities, and the mass of the impurities is less than that of the waste plastics, the wind separator can separate plastics and impurities by making them produce distance differences during the drifting process according to the differences in density, shape or particle size of different plastics through the action of airflow, so as to discharge the waste plastics from the plastic discharge end 403, and discharge the impurities from the impurity discharge end 402, and transport them to the impurity collection box 405 through the connecting pipe 404. It should be noted that the wind separator in this embodiment is an existing wind separator, and this embodiment does not improve it. Furthermore, a wind shield 406 is provided on the top of the wind separator to prevent the impurities from being transported. The path is offset.

[0043] It should also be noted that, in this embodiment, the first transmission assembly 107, the second transmission assembly 206 and the third transmission assembly 505 are preferably pulley transmission assemblies.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
