Description

T-shaped double-discharging device on melt pump

Technical Field

The pump mainly comprises a pump shell, a driving gear, a driven gear, a sliding bearing, a front end plate, a rear end plate, a filler seal and the like. The feeding area, the material conveying area and the material discharging area of the pump are formed by the tooth profiles of the two gears, the pump body and the side cover plate. During operation, melt is conveyed by means of the change of the working volume caused by the mutual meshing of the driving gear and the driven gear. When the gear rotates in a specified direction, the melt enters the tooth grooves of the two gears in the feeding area, the melt is brought into the conveying area from two sides along with the rotation of the gears, and the gears are meshed again, so that the melt in the tooth grooves is extruded and is pressed and conveyed to the outlet pipeline. The melt pump pressurizes the high-temperature plastic melt from the extruder, and the flow is stably sent to the extruder head after pressure stabilization, because a large shearing force is generated when the high-temperature plastic melt is rapidly extruded, the temperature in the pump is rapidly raised, so the temperature needs to be reduced in the working process of the pump body, the existing method for reducing the temperature of the melt pump generally leads cooling water to an interlayer in the pump to take away heat, the cooling is carried out, or an external fan is adopted for cooling, but the cooling effect is common, however, the existing utility model utilizes the cooling water to pass through the inside of a cooling device to reduce the temperature of the surface of the melt pump, most of the high temperature of the melt pump comes from the inside of the melt pump, the temperature is only reduced on the surface, the distance between the cooling device and the high-temperature plastic melt is far, only the heat can be dissipated on the surface of the melt pump, the temperature in the inside cannot be directly reduced, therefore, the defect exists, and the existing melt pump only has a single discharge port, when the output material speed, lead to the discharge gate easily so that melt pump is inside can cause the jam, influence the efficiency of ejection of compact, moreover because the discharge gate blocks up the material that still can become in the melt pump and can't get rid of, cause the damage of melt pump internals, and reduce melt pump's life.
