Description

Dustproof sand making machine of feeding

Technical Field

Background

According to the patent document with the application publication number of CN105728102A, the utility model is named as a twin-roll type internal driving sand making machine, and the specification of the patent document is as follows: the hydraulic motor of the hydraulic station inputs hydraulic oil into the hydraulic cavity to drive the piston, the piston drives the driving rod to drive the sliding frame to move so as to adjust the gap and crushing pressure of the crushing roller, and meanwhile, the gas in the gas storage cylinder is extruded by the hydraulic oil to store energy. When the force is instantaneously increased due to the fact that large sand particles pass through the crushing roller in the crushing process, the piston is extruded to move towards the hydraulic cavity, at the moment, the gas in the gas storage cylinder is extruded to deform to provide a space for the piston to move back, and the phenomenon that equipment such as the crushing roller is damaged even is blocked due to the fact that the instantaneous pressure is not increased too much is avoided. When the piston is in poor sealing, leaked oil is collected in the oil collecting cavity and finally flows back to the oil tank through the oil return hole, so that waste and environmental pollution are prevented, but the following defects still exist:

the material is an open type material, so that excessive dust is more, and the environmental pollution is large;

the crushed sand cannot be screened, and the granularity of the produced sand is not in line with the requirement;

in order to continuously open and discharge, more dust is generated during discharging.
