Sand washing system and debugging method

Abstract

The invention relates to the technical field of sand making, in particular to a sand washing system and debugging method. The sand washing system comprises a vibrating screen, a sand washing tank, a wheel type bailing machine, a fine sand extracting machine, a high pressure pump, a dewatering screen and a conveyor belt. A discharge hole of the vibrating screen is connected to a feed inlet of the sand washing tank, and the wheel type bailing machine is disposed on the sand washing tank. The fine sand extracting machine is connected with the sand washing tank through the high pressure pump, anddischarge holes of the wheel type bailing machine and the fine sand extracting machine are separately connected with the dewatering screen. A discharge hole of the dewatering screen is connected withthe conveyor belt. According to the sand washing system and debugging method, medium sand and fine sand in the sand washing tank are correspondingly extracted by the wheel type bailing machine and thefine sand extracting machine so as to avoid the massive loss of the fine sand, and the effective control over the fineness modulus of mechanism sand is realized; and the mechanical sand is subjectedto dewatering by the dewatering screen to enable the moisture content of the mechanical sand to meet the engineering requirements.

Description

【Technical field】 [0001] The invention relates to the technical field of sand making, in particular to a sand washing system and a debugging method thereof. 【Background technique】 [0002] The traditional sand making production line often adopts wet process in areas rich in water resources, so it is easy to cause serious loss of fine sand (sand particles with a particle size above 0.16mm), and some even exceed 20% loss rate, which not only causes serious It also seriously affects the gradation of sand (the proportion of fine sand), making the fineness modulus of sand and gravel coarser, which greatly reduces the product quality of machine-made sand; and the discharge of a large amount of fine sand will also cause environmental damage. pollute. In addition, the wet process is also likely to cause the moisture content of the sand and gravel to fail to meet the standards for engineering construction. [0003] Therefore, the gradation (fineness modulus), moisture content and o...
