Automatic circulating cooling sand-building treatment system for iron and steel castings

Abstract

The invention provides an automatic circulating cooling sand-building treatment system for iron and steel castings. The automatic circulating cooling sand-building treatment system comprises a castingand casting sand separation unit, a casting sand lifting treatment unit, a casting sand loading and vibrating unit and one or more casting sand cooling units, and corresponding devices of the castingsand loading and vibrating unit are arranged below sand outlets of corresponding devices of the casting sand cooling units. According to the automatic circulating cooling sand-building treatment system for the iron and steel castings, the technical problems that when hot casting sand of existing castings is cooled and then filled into a sand box together with the castings for sand building treatment, the occupied production area and space are large, the cooling effect is poor, the hot casting sand makes insufficient contact with a cooling liquid and an air cooling medium, and the labor intensity of worker operation is low are solved. Compared with the prior art, excellent product rate of casting production of the castings is increased by 30% or above, compared with an existing cooling device for hot sand after casting, the energy consumption is saved by 40% or above, and moreover, the environmental protection is realized.

Description

Technical field: [0001] The invention relates to a technological device in the technical field of iron and steel castings such as lost foam casting, in particular to an automatic circulating cooling sand-making treatment system for iron and steel castings. Background technique: [0002] In the iron and steel casting industry, especially in the field of lost foam casting technology, due to the continuous improvement and development of new lost foam casting technology, its technology is constantly improving and improving. Lost Foam Casting is generally to bond and combine paraffin or foam models similar in size and shape to the castings to form a model, brush and dry the refractory paint, put the model in the sand box, then fill it into the casting sand and vibrate the shape, and finally in the negative Press down and pour to vaporize the model, the liquid metal occupies the position of the model, solidifies and cools to form a casting, and after the casting is taken out of th...

AI Technical Summary

Problems solved by technology

[0006] The present invention is to provide an automatic circulating cooling sand processing system for iron and steel castings, which includes a casting sand separation unit, a casting sand lifting processing unit, a casting sand loading and sand shaking unit, and one to several casting sand cooling units. The corresponding device of the sand unit is located below the sand outlet of the corresponding device of the casting sand cooling unit; it overcomes the hot casting sand of the existing castings for cooling, and then fills the sand box together with the castings for sand processing. Occupies a large production area and space, poor cooling effect, insufficient contact between hot casting sand and cooling liquid and air-cooling medium, low labor intensity for workers, etc., and is environmentally friendly
