Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Examples
An air-cooled sand outlet hopper of a sand warehouse for lost foam casting is shown in figures 1-7 and comprises a hopper body 1 and an air cooling device 2; a flange plate 101 is arranged at an outlet at the bottom of the bucket body 1; the upper part of the bucket body 1 is provided with an air cooling device 2, and the air cooling device 2 comprises an inverted V-shaped plate 201, a support rod 202 and an air cooling pipe 203; the front end of the inverted V-shaped plate 201 is fixedly connected to the upper part of the front side of the inner wall of the bucket body 1, the rear end of the inverted V-shaped plate 201 is fixedly connected to the upper part of the rear side of the inner wall of the bucket body 1, and a plurality of support rods 202 are uniformly distributed at the lower part of the inverted V-shaped plate 201; the front side surface of the bucket body 1 is communicated with an air cooling pipe 203, and the air cooling pipe 203 extends into the bucket body 1 and is positioned above the supporting rod 202; a plurality of air holes 204 are uniformly distributed on the end part of the air cooling pipe 203 in the hopper body 1 along the circumferential direction, and a blocking plate 206 is arranged on the end part of the air cooling pipe 203 close to the rear side surface of the hopper body 1.
