the characteristics and USES
This series of resin sand sand mixer is to absorb the advantages of similar foreign advanced equipment, the optimization design, by repeated improvements, and assessment of long-term production and development of new products, mixing is the ideal equipment of resin sand and sodium silicate sand, has the following advantages:
(a) resin, curing agent pump quantitative precision (plus or minus 2% or less), which can realize various proportioning, without downtime calibration.
(b) sand mixing uniformity, good sand mixer basic headless backfilling materials in the process of start, stop loss.
(c) the unique structure design, the device is aesthetically pleasing, and ensure the equipment performance.
(d) sand mixer adopts full open stir over walls, easy to stir all wall, blade clearance and the adjustment of the blade and replace.
(e) electric control system adopts programmable controller, and set up the restriction of protection and fault display, reliable operation, and convenient for operation and maintenance.
2, the structure and working principle
This machine is composed of sand body, binder conveying system, pneumatic system, electrical system.
Frame supporting and fixing sand, binder system, pneumatic system, electrical control system etc.
Sand mixer in the sand by the proximal control valve to join the curing agent, curing agent with the sand by the spiral vane conveying forward, proximal control valve to join resin resin, uniform mixing in sand mixer. Sand segment of small blade is adjustable, can adjust clearance of blade and stir over walls, to compensate for a greater gap caused by wear, and can adjust the blade and the axis into a different point of view, make the direction and speed of the sand, to strengthen the ability of penetration between sand, sand mixing of effect.
Binder supply system: the diaphragm pump, gear pump and proximal control valves, limit switches, realize quantitative supply of binder, ensure adhesive quantitative accuracy.
Pneumatic system: electric reversing valve, cylinder, pneumatic components, the implementation of slewing brake, proximal control valve, positioning pin, sand control of the gate.
Electrical control system: USES the advanced automatic control, programmable controller (PLC) is configured with simulated dynamic display screen, set up automatic fault alarm devices, and make full monitoring and simple operation, protected fully.
