Uniform temperature throughout the drying tunnel by the strong convection of the hot air heating fan
The vacuum impregnation is vacuumed by a water ring vacuum pump and driven by an MM430 inverter. The extrusion part is mirrored by two single-screw extruders, and the MM440 vector inverter is used to control the extrusion variable frequency motor. The system selected 3 Siemens S7-226PLC, one for the total control of the system, two for the control of the left and right extruders, and equipped with Axiom technology GOT-3150T-800WT touch fanless industrial computer as the person Machine Interface (HMI), the temperature control unit used a total of 30 Honeywell DC1020 intelligent temperature control table to implement closed-loop temperature adjustment. There are currently three heating methods for continuous processes: hot oil carrier and direct gas (or fuel). The electric heating tube mainly heats the belt body by heat radiation, and the heat distribution in the drying tunnel is uneven, which is easy to cause the belt body to be less plasticized or over-plasticized, and the energy consumption is high; the hot oil carrier and the direct gas (or fuel) pass. Hot air heating, the strong convection of the fan makes the temperature throughout the drying tunnel uniform, so that the PVC plasticizing paste inside and outside the core can be plasticized evenly and completely; the difference is that the former heats the heat-conducting oil first, and then the oil pump forcedly circulates through the heat exchanger. The air is heated, and the latter directly heats the air in the combustion chamber gas (or fuel). In comparison, direct combustion heating has lower energy consumption because there are no two heat exchanges and the air passage is shorter. The production line adopts the plasticizing process of direct heating of natural gas. The drying and plasticizing tanks are equipped with 5 sets of progressive BTG15ME integrated burners of Italy Baide Company to control gas combustion, and 5 sets of Siemens MM430 fan and water pump special type frequency conversion The fan is driven to perform hot air circulation. Three sets of far-infrared electric heating tubes are used as auxiliary heating for the plasticizing box, which is used for coating the rapid gel of the paste, and is controlled by the thyristor power controller.
