Abstract

The invention provides a novel sand removing method and device. The device comprises a drilling device for sand cleaning and a dust collecting system based on the rotating cutting and crushing principle and the Bernoulli principle. The drilling device mainly comprises a drill bit, a rotating rod and a three-way communicating pipe, wherein the drill bit is connected with the rotating rod, and the rotating rod is used for exerting rotating cutting force on the drill bit to which the drill bit belongs; and the rotating rod connected with the drill bit sleeves the dust suction end of the three-waycommunicating pipe, and the rotating rod is provided with a gap in the dust collecting end of the three-way communicating pipe, so that dust can be prevented from passing through the dust collectingend; the rotating rod is connected with a power source, and the rotating power is provided; and the end a in the other two ends of the three-way communicating pipe is an air inlet end, and the end b is an air outlet end; and a negative pressure is formed at the dust suction end of the three-way communicating pipe when the gas flows from the air inlet end to the air outlet end at a high speed, andthe dust generated by rotary cutting of the dust suction end drill bit is sucked into and enters the dust collecting system from the air outlet end in the flowing direction of the gas. The method aimsto solve the problem of difficulty in sand cleaning in the existing casting production post-treatment process, dust pollution, high noise pollution and the like are solved; and a new method is provided for solving the problems of large dust pollution, large noise pollution and the like.
