The double-shafts horizontal mixer is mainly composed of the casing, screw shaft assembly, driving device, piping, cover plate, chain cover and other components.
Specific structure and performance characteristics of double-shafts horizontal mixer:
1. The shell is mainly composed of sheet metal and section steel. It is welded and formed in the manufacturing plant and assembled with other parts. It is the support of the two-axis mixer. The shell is tightly sealed, and there will be no fly ash lifting and leaking.
2. Spiral bearing is the main component of double-shafts mixer. Its main components are left and right spiral shaft, bearing seat, bearing sleeve, bearing cover, gear, sprocket, oil cup, blade and other parts.
The left and right rotational helical shafts have high manufacturing accuracy and good technological performance. They have strict matching requirements with bearing seat, bearing sleeve and bearing cover. The modulus of gear is 8, the number of teeth is 60, the angle of tooth shape is 20°, the pitch of sprocket is 50.8, the number of teeth is 25, and the shape of teeth is GB1224-85. Gears and sprockets are protected by protective shields, which can operate safely and effectively. The oil cup is a pressure matching type pressure injection cup, which is convenient and effective for adding lubricating oil. Composite ceramics which are wear-resistant and not easy to adhere to ash are selected for the blades of the two-axis mixer. The blade structure design is reasonable and simple, easy to replace after wear and tear, and has long service life.
3. Water and humidity regulating pipes are mainly composed of nozzles, connectors and nozzles. The spray nozzle is made of stainless steel atomizing cone nozzle, which is arranged above the inner part of the mixer shell and arranged axially along the spiral axis to form a water curtain to facilitate the wetting and stirring of materials. The nozzle is simple in structure, easy to replace, stainless steel material, anti-corrosion and durable. The moisture content of wet ash can be adjusted by operating the manual regulating valve on the water supply pipeline.
4. The cover of double-shafts mixer mainly includes the left cover, the middle cover, the right cover, the hole cover and the overhaul hole cover. Six repair holes are arranged on both sides of the two-axis mixer to facilitate the normal maintenance and repair of the operators. The two-axle mixer is used at the end of pneumatic conveying.
