Description

TECHNICAL FIELD

[0002] The recycling of waste plastics is an important environmental protection action, which can effectively reduce plastic pollution and provide resources for reuse. There are two main recycling technologies at present. The physical recycling method: through mechanical means, waste plastics are crushed, washed, melted and processed into new plastic products. Specifically, the collected plastic waste usually needs to be washed and treated to remove surface dirt, residues and other pollutants. This step ensures that the recycled plastics are clean and suitable for further processing. The washed plastic waste is usually sent to a special device for crushing or breaking. This step physically breaks down the waste plastics into smaller particles or blocks for subsequent processing and treatment. The crushed plastics are sent to a melting device to convert the plastics into plastic liquid by heating and melting for subsequent reshaping and utilization.

Each contact rod is provided with a washing plate at the end. The blocking component of the invention can press down the plastic waste floating on the water surface, so that the plastic waste is completely immersed in water. The auxiliary blocking of the rubbing action of the washing plate can completely clean the debris on the plastic waste.

[0043] The crushing box 21 is fixedly installed with a power source one 211, a crushing roller 212 is fixedly installed on an output shaft of the power source one 211, a gear one 213 is fixedly installed on the crushing roller 212, a gear two 214 is engaged with the gear one 213, a transmission shaft is fixedly installed on the gear two 214, and a conveying belt 215 is drivingly connected with the transmission shaft, a plurality of sets of crushing rollers 212 are provided, the plurality of sets of crushing rollers 212 are drivingly connected through the gear one 213, after the blocking plate 23 is opened, the waste plastic falls downward and enters the crushing roller 212, the power source one 211 drives the crushing roller 212 to rotate, a plurality of sets of waste plastics are crushed, the gear one 213 drives the gear two 214 to rotate, the conveying belt 215 drives the crushed waste plastic to be conveyed to the incinerator 1 through the discharge port 25, the waste plastic is recycled through the incinerator 1, and resource waste is avoided.

[0044] The power source one 211 is preferably an electric motor.

[0045] It should be noted that when the incinerator 1 incinerates the waste plastic, waste gas and waste residue are generated, the waste gas is directly discharged to the outside to seriously pollute the external environment, the flue gas is usually purified through a purification device, but the waste of residual heat in the flue gas is caused, and the heat in the flue gas also increases the load of the purification device.

[0046] Therefore, the application is provided with the exhaust port 11 on the incinerator 1, the protective shell 111 fixedly installed on the exhaust port 11, the heat exchange pipe 112 penetrating through the protective shell 111, the drying pipe 113 for drying the waste plastics, the gas distribution pipe 114 communicated with the drying pipe 113, and the gas source communicated with one end of the heat exchange pipe 112.

[0047] Specifically, since the heat exchange pipe 112 is coiled on the surface of the exhaust port 11, when the gas source sends gas into the heat exchange pipe 112, the temperature of the exhaust port 11 and the waste smoke can be exchanged to reduce the influence of the high-temperature waste smoke on the purification device, and ensure the use effect of the purification device. The gas in the heat exchange pipe 112 moves to the drying pipe 113 and the gas distribution pipe 114 to dry the cleaned waste plastics, so as to ensure the drying effect of the waste plastics.

[0048] The gas outlet end of the gas distribution pipe 114 is communicated with the material collecting box 221, which can blow and dry the waste plastics temporarily stored in the material collecting box 221, and improve the treatment effect of the water stains on the surface of the waste plastics.

[0049] The drying pipe 113 is provided with the fixed frame 1131 communicated with the drying pipe 113, the reciprocating screw rod 1132 slidingly connected to the fixed frame 1131, the connecting piece 1134 threadedly connected to the reciprocating screw rod 1132, and the connecting piece 1134 fixedly installed on the fixed frame 1131. The fixed frame 1131 is communicated with the exhaust pipe 1135, one end of the reciprocating screw rod 1132 is fixedly installed with the supporting rod, the straight groove is formed on the supporting rod, the blade 1133 is slidingly connected to the straight groove, the blade 1133 is arranged in the fixed frame 1131, the fixed frame 1131 is fixedly installed on the crushing box 21, the both ends of the reciprocating screw rod 1132 are rotatably connected with the fixed plate 11321, the fixed plate 11321 is fixedly installed with the discharging plate 11322, and the discharging plate 11322 is rotatably installed on the discharging hopper 22.

[0050] The gas is sent into the fixed frame 1131 through the drying pipe 113, and then is discharged to the discharging box 222 through the exhaust pipe 1135. The gas is blown upward by itself, and the waste plastics are dried from the bottom. The drying effect is better. That is, the gas is exchanged through the drying pipe 113 and the gas distribution pipe 114, and the waste plastics are dried from the side and the bottom. The drying effect is better.

[0051] In detail, the gas enters the fixed frame 1131, drives the blade 1133 to rotate the reciprocating wire rod 1132, moves the reciprocating wire rod 1132 axially under the action of the connecting piece 1134, and drives the blanking plate 11322 to swing, so that the waste plastics can be quickly and uniformly guided to the crushing roller 212 under the action of the blanking plate 11322 when the waste plastics are discharged, a plurality of crushing rollers 212 synchronously crush the waste plastics, the load of the local crushing roller 212 is reduced, and the crushing efficiency of the waste plastics is improved. It should be noted that when the reciprocating wire rod 1132 moves, the support rod is slidably connected with the fixed frame 1131 to avoid shaking of the reciprocating wire rod 1132 when moving, and the gas drives the blade 1133 to rotate and is discharged through the exhaust pipe 1135 to blow and dry the waste plastics, and the use effect is good.

[0053] When the gas is discharged through the exhaust pipe 1135, the piston 11352 is driven to move upward with the lifting rod 11353, so that the push block 11354 pushes the blocking plate 23 to shake, and when the piston 11352 moves through the pressure relief port 11351, the gas is discharged through the pressure relief port 11351, so that the piston 11352 and the lifting rod 11353 move downward, and in turn drive the push block 11354 to move up and down to bridge the blocking plate 23, and shake off the moisture on the waste plastics, further improving the treatment effect of the moisture on the surface of the waste plastics, and the use effect is good.

[0054] In general, when the waste gas discharged from the incinerator 1 is cooled by the heat exchange pipe 112, on the one hand, the gas with temperature after heat exchange is blown to the waste plastics from the bottom and the side of the waste plastics to remove the moisture on the surface of the waste plastics, and on the other hand, when the gas enters the fixed frame 1131, the blade 1133 is driven to rotate, the reciprocating wire rod 1132 drives the blanking plate 11322 to swing, the waste plastics are discharged more uniformly, and when the gas is discharged from the exhaust pipe 1135, the push block 11354 knocks the blocking plate 23, further improving the treatment effect of the moisture on the surface of the waste plastics, and the use effect is good.
