Abstract
The invention discloses an online mortar recovery method in silicon industry. The online mortar recovery method is mainly characterized in that a solid phase port of a primary separation centrifugal machine is connected with a separating tank, and a self-circulation loop of the separating tank is switched to a recovery cooling liquid adding loop through motor-driven valves. A blending tank forms a self-circulation loop with the motor-driven valves, a pneumatic diaphragm pump, a mass flowmeter and the like. The self-circulation loop of the blending tank and the self-circulation loop of the separating tank share one pneumatic diaphragm pump and one quality flowmeter. Mortar is conveyed into the blending tank after the mortar density reaches a set value and the blending tank sends out a signal allowing mortar loading. Recovery cooling liquid is added into the separating tank after the conveying is finished. The online mortar recovery method has the advantages that by adoption of blending and separating technologies, the use ratio of the primary separation centrifugal machine reaches over 98% and the handling capacity is improved by about one time. Meanwhile, the performance of recycled mortar is well guaranteed and the uniformity degree of matching is improved.
