s5: waste gas when getting into the case that gathers materials, the cold pipe that leads of accessible type of falling V passes through cross shower and shower nozzle with the air conditioning in the water storage chamber and sprays around the electro-magnet for air conditioning and high temperature waste gas contact reduce the inside temperature of case that gathers materials, avoid the phenomenon that the electro-magnet appears losing magnetism under high temperature state.

The working principle is as follows: when the device is used, a user adds synthetic rubber powder into the feeding hopper 9, the motor 12 is utilized to drive the two spiral feeding rollers 20 and the connecting rod 25 to rotate, so that the synthetic rubber falls into the plasticizing box 2 along the spiral feeding rollers 20 and the material guiding opening, feeding operation is carried out, the electromagnet 19 is started, in the feeding process, the metal material in the rubber can be adsorbed and collected by the electromagnet 19, the heater 13 and the heating pipe 22 are used for heating the interior of the plasticizing box 2 for desulfurization and plasticizing, when the connecting rod 25 rotates, the first transmission shaft 23 can be driven by the first tooth motion structure 26 to rotate, the X-shaped stirring frame 24 is driven to rotate in the plasticizing box 2, the synthetic rubber is stirred, so that the heating is more complete, the electromagnetic valve of the discharging pipe 4 is opened, and the rubber heated to a certain degree flows into the shaping chamber through the discharging pipe 4 to be stored, the water in the water storage chamber is refrigerated through the refrigerator 6 and the refrigerating sheet 17, the interior of the shaping chamber is cooled through the cold guide plate 16, plasticized rubber can be obtained, the access door 3 is opened for discharging, and more waste gas is generated in the heating and cooling stages, because high-temperature waste gas directly enters the interior of the material collecting box 10 through the material collecting port 21 and enters the interior of the feed hopper 9 through the conveying cylinder 8, the waste gas in the material collecting box 10 can be guided into the interior of the feed hopper 9 through the air return pipe, when the spiral feed roller 20 rotates, the rotating shaft 15 can be driven to rotate through the transmission assembly 7, the second transmission shaft 27 is driven to rotate through the second tooth movement structure 29, the air exhaust fan blades 28 are driven to form an air exhaust phenomenon in the interior of the exhaust pipe 5, so that the waste gas collected in the feed hopper 9 can be pumped into the interior of the water storage chamber through the air distribution pipe 30, waste gas is subjected to dust fall, purification and other treatment, when the waste gas enters the material collecting box 10, the cold air in the water storage chamber is sprayed around the electromagnet 19 through the cross spray pipe 18 and the spray heads by the inverted V-shaped cold guide pipe 11, so that the cold air is contacted with the high-temperature waste gas, the temperature inside the material collecting box 10 is reduced, and the phenomenon of magnetic loss of the electromagnet 19 in a high-temperature state is avoided.
