Description

Molding sand detection machine with built-in sand collection

Technical Field

The utility model relates to the field of molding sand detection equipment, in particular to a molding sand detection machine with built-in sand collection.

Background

In the operation of the sand mixer, online sampling detection of the molding sand is required. The principle of the detection equipment is that the sampled molding sand is compacted by adopting the pressure of 1MPa, and the percentage of the change of the volume of the sample before and after compaction is obtained and is expressed by the percentage of the change of the height of the sample before and after compaction. The molding sand for machine molding has a compaction ratio of approximately 50% in a dry and wet state, 35-45% in high-pressure molding and air-impact molding, 35-40% in extrusion molding, and the degree of dry and wet feeling of hand kneading is in an optimum state as long as the compaction ratio is controlled within the above range, regardless of the contents of the sand seed effective bentonite, pulverized coal and ash, and the moisture of the molding sand can be said to be optimum moisture.

In sand detection, the molding sand in a sand mixer needs to be sampled generally, the sampled sample is taken into a telescopic vessel through a material receiving port arranged on one side, and then enters the machine through a telescopic stroke, is compacted and detected through a pressing block, and is discharged from the bottom. The process of receiving and filling and the process of discharging sample sand can pollute the bottom surface, and cause sand leakage and shakeout everywhere. Although some workshops can use basins or boxes to collect sand at the bottom, because the detection vessel is positioned in the detection machine, when the detected sample sand falls down, the frames and other components in the machine can be polluted, after a period of operation, the frames and components below the vessels in the machine can be full of sand, and obvious sand dust can be generated, so that the pollution in the machine is serious, and the service life of pneumatic elements is influenced.
