Specifically, when the sand water concentration in the material for sand blasting needs to be detected, the shunt pipeline is opened, the sand water sample is conveyed into the cylinder body 310 through the shunt pipeline, and when the liquid level of the sand water sample reaches the third preset height h3, the third sensor 340 outputs a signal to control the sand water sample to stop entering. After the sand in the cylinder 310 is settled, the first sensor 320 and the second sensor 330 start to detect the content of the sand, if the measured height of the sand is lower than the second preset height h2, it indicates that the proportion of the sand in the mixed sand in the stirring tank 110 is insufficient, a signal is output to control the sand supply device 40 to add the sand into the stirring tank 110, and if the measured height of the sand is higher than the second preset height h2, the sand supply device 40 is not required to add the sand into the stirring tank 110.

When the sand-water liquid level sensor works, the signal transmitting end of the sensor sends out an optical signal, the optical signal penetrates through the cylinder body 310 and is received by the signal receiving end on the other side of the cylinder body 310, and when the sand-water liquid level reaches the third preset height h3, the optical signal of the third sensor 340 is blocked due to the fact that the sand-water mixed liquid is opaque, and therefore the third sensor outputs signals to the sand blasting machine.
