Brazil water-cooled fluidized bed project

Water-cooled boiling cooling bed is the most widely used sand cooling equipment in investment casting and disappearing mold casting. Dense cooling water pipe can quickly complete the heat exchange, although the structure is complex, high energy consumption, strict requirements on the particle size of the sand, but the cooling effect is good, to meet the requirements of the casting process.

Features:
This series of equipment can remove metal particles and micro powder film while cooling and removing film. It is widely used in large and medium-sized resin sand production lines.
The water-cooled boiling cooling bed is a continuous cooler. After the loose old sand enters the fluidized bed, it is in a boiling state under the strong blowing of the high-pressure fan, and starts to boil around the densely packed cooling pipes from the sand inlet. Under the action of strong exhaust and cooling water, the old sand can be fully cooled and film removed.Cooperating with closed cooling tower can ensure cooling water circulation in the whole cooling process.

The excitation source of this machine is caused by two sets of linear mechanical vibrations that rotate synchronously with biased weights on both sides. The connection between the excitation main shaft and the power source is through a set of elastic rubber couplings. In the working state, the power source does not participate in vibration and has strong vibration resistance. Due to the use of a biased weight block structure, its amplitude and excitation force are adjustable, and the excitation amplitude and excitation force can be adjusted according to the structural size of the castings to be conveyed by falling sand. The grid orifice plate can be made into structural parts with welded or punched holes according to the shakeout effect.

It is used for sand boxing in the sand treatment system (automatic molding line or production line) in the foundry workshop. It can separate the castings from the sand box and achieve the effect of sand transport at the same time. It is especially suitable for the sand castings without box shape.

Installation requirements: The machine frame must be reliably installed on the reinforced concrete foundation. The horizontal accuracy of the installation (including the coaxiality of the main shaft and the power source and the verticality to the tank body) allows an error of 1000mm and a measurement length of ≤1.5mm. The anchor bolts connecting the machine to the foundation must be dustproof and reliable. The connection between the machine and other equipment should be made of flexible materials, with a gap > 2.5mm.
Add lithium-based grease to the lubrication points regularly twice a month. After each shift, the iron debris in the tank should be cleaned, and the fastener connections at each fastening point should be checked regularly.
