Detailed Description
Referring to fig. 1 to 3, a sand silo for an asphalt mixing plant comprises a frame 1, a silo body 2, a conveying belt 5, a material door mechanism 6, a proximity switch 7, a control device, two air cannon arch breaking devices 3 and two vibrators 4, wherein the silo body 2 is arranged on the frame 1, the conveying belt 5 is arranged below the silo body 2, the material door mechanism 6 is arranged on the silo body 2 and is provided with a material door capable of moving up and down relative to the conveying belt 5, and the proximity switch 7 is arranged on the frame 1 and is used for detecting the discharging condition of the silo body 2 and feeding back the discharging condition to the control device.
The control device is respectively connected with the proximity switch 7, the vibrator 4, the air cannon arch breaking device 3, the material door mechanism 6 and the conveying belt 5, and the control device can control the working states of the air cannon arch breaking device 3 and the vibrator 4 according to signals fed back by the proximity switch 7 and can control the opening degree of the material door mechanism 6 and the working state of the conveying belt 5.
The bin body 2 is in a conical structure surrounded by four side walls, the two air cannon arch breaking devices 3 are symmetrically arranged on two opposite side walls of the bin body 2, and the two vibrators 4 are symmetrically arranged on the other two opposite side walls of the bin body 2.
The air cannon arch breaking device 3 comprises a gas storage tank 31, a cannon barrel 32, a pressure relief chamber A, an exhaust valve 35 and a spray pipe 33, one end of the cannon barrel 32 extends into the gas storage tank 31, the other end of the cannon barrel extends out of the gas storage tank 31, one end of the spray pipe 33 is connected with the other end of the cannon barrel 32 through a flange, the other end of the spray pipe extends into the bin body 2, the opening of the spray pipe faces to the lower port of the bin body 2, and the spray.
