Embodiment 7
[0045] In Embodiment 7 and Embodiment 8, the injection flow rate of the sand-water mixture is changed, that is, the component force in the horizontal direction is increased, the horizontal component force increases, and the quartz sand particles at the sand outlet gradually increase, and the horizontal component force affects the outlet. The particle size of the quartz sand in the sand port has a greater influence.
Embodiment 8
[0046] In Examples 8 and 9, the injection rate of the sand-water mixture increases, the flow rate of the gas increases, and the particle size of the quartz sand particles in the sorting box 1 and the sand outlet increases. In summary, the sorting of quartz sand particles is affected by the horizontal component force (injection flow rate of the sand-water mixture) and the vertical component force (gas flow rate injected into the sorting box 1).
[0047] In Example 10 to Example 13, the height of the dividing plate was gradually increased, that is, the resistance of the horizontal component force (injection flow rate of the sand-water mixture) was gradually increased, and the horizontal component force was reduced. The particle size of the quartz sand particles decreases gradually, and the particle size of the quartz sand in the two sorting chambers 2 increases gradually.
[0048] To sum up, when screening quartz sand particles of different sizes, the injection amount of sand-wa...
