Liquid sand blasting machine with adjustable sand blasting density

Abstract

The invention discloses a liquid sand blasting machine with adjustable sand blasting density. The liquid sand blasting machine comprises a sand blasting machine body and an abrasive cavity, wherein the abrasive cavity is arranged on the sand blasting machine body and opens upwards; a sheave device is arranged below the abrasive cavity and comprises a sheave cavity formed in the lower wall of the abrasive cavity; a sheave is rotatably arranged in the sheave cavity; six notches are uniformly distributed on the circumferential end surface of the sheave; the side edges, away from the axis of the sheave, of the inner walls of every two adjacent notches are connected; and an excessive material discharging device and a liquid replenishing device are arranged in the sand blasting machine body. According to the liquid sand blasting machine with the adjustable sand blasting density, the amount of conveyed abrasive is adjustable while continuous conveying of the same amount of the abrasive at a constant speed is ensured through the sheave device, then the density of grinding liquid can be changed to adapt to grinding requirements of different parts, and the adaptability is high; and a feedingchannel can be automatically opened or closed when the grinding operation is started or stopped, so that the abrasive in the sheave is conveniently stopped from being discharged after the grinding operation, and the liquid replenishing device is able to automatically start or stop the liquid replenishing process according to the water level change in a water storage cavity.

Description

technical field [0001] The invention relates to the technical field of sandblasting machines, in particular to a liquid sandblasting machine capable of adjusting sandblasting density. Background technique [0002] Sand blasting machine uses compressed air to transport powdery granular materials from one place to another in the pipeline, and in the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object to improve the surface quality of the object. Among them, the liquid sandblasting machine has well controlled the dust pollution in the sandblasting process and improved the working environment of the sandblasting operation. The sandblasting density can be flexibly and quickly adjusted according to different grinding requirements, and there is often the problem of uneven mixing of grinding fluid. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the...

AI Technical Summary

Problems solved by technology

[0004] Most of the current liquid sandblasting machines need to mix the abrasives and water evenly before operating. They cannot flexibly and quickly adjust the sandblasting density according to different grinding requirements, and there is often the problem of uneven mixing of the abrasive liquid.
