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

Embodiment 1

[0040]The invention discloses an automatic circulating cooling sand processing system for iron and steel castings. This embodiment uses a set of casting sand lifting processing unit and casting sand cooling unit to form an integral cooling device. The two above cooling devices are connected together. A cooling system for the casting sand is formed in series to cool the hot casting sand, that is, the hot casting sand is cooled by the casting sand cooling device in the sand storage box device 7 of the first sand storage device, that is, the casting sand cooling unit, and then cooled from the lower sand storage The sand outlet (29) at the outlet end of the bucket (24) is sorted by the air separator 8 and then transported to the casting sand cooling unit of the second sand storage box device 10 by the belt type sand conveyor 9 after being cooled and then enters In the casting sand box 12, the casting is sanded. The following is a detailed description of the specific implementation...

Embodiment 2

[0047] In this embodiment, a set of casting sand lifting processing unit and casting sand cooling unit are used to form an integrated cooling device, that is, the hot casting sand first passes through the first sand storage device, that is, the sand storage box device 7 of the casting sand cooling unit. After the casting sand cooling device is cooled, it is sorted by the air separator 8 and then transported by the belt sand conveyor 9 or directly enters the casting sand box 12 through the chute 27 to process the castings. The following is a detailed description of the specific implementation process. The foundry sand used in the present invention is commonly used molding sand during the existing lost foam casting.

[0048] The raw material used in this embodiment is all scrap steel smelting, and the furnace charge composition is A3 steel plate and silicon steel sheet each accounting for 50%, plus an appropriate amount of recarburizer, ferrosilicon, etc.; the smelting temperatu...

Abstract

The invention provides an automatic circulating cooling sand processing system for iron and steel castings, which includes a casting sand separation unit, a casting sand lifting treatment unit, a casting sand loading and sand shaking unit, and one to several casting sand cooling units. The corresponding device is located under 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, occupying the production Large area and space, poor cooling effect, insufficient contact between hot casting sand and cooling liquid and air-cooling medium, and low labor intensity for workers to operate. More than 30%. Compared with the existing cooling device for hot sand after casting, the energy consumption can be saved by more than 40%. And environmentally friendly.

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...
