Embodiment Construction

[0059] Below in conjunction with accompanying drawing and specific embodiment the utility model is further described;

[0060] Such as figure 1 , 2 . As shown in 3, the cross-flow sand and mud washing and separating device includes a straight cone with a straight ring and a pointed bottom, a tank with a pointed cone at the top and a sand discharge valve 57 installed at the bottom of the cone, and a sand washing and separating cylinder 1 The interior is divided into energy dissipation chamber 22, sand guide buffer chamber 24, rectification chamber 23, sand collection chamber 25 and sand guide chamber 26 and other parts. The energy dissipation chamber 22 is the inner space of the energy dissipation cylinder 3. The energy dissipation cylinder 3 is placed on the axis line edge of the sand washing separation cylinder 1, and the axis lines of the two are coincidently arranged. The top of the separation cylinder 1 is at the same height, the energy dissipation cylinder 3 is a hollo...

Abstract

The invention relates to a method for obtaining clean sand particles meeting the requirements by washing sand and mud in a soil and sand mixed liquid through rising washing water, in particular to a method for introducing the rising washing water to separate the sand particles from sludge to achieve the purpose of washing and selecting high-quality sand particles by using the property that the sludge and the sand particles in the soil and sand mixed liquid have different settling rates in water.

Description

technical field [0001] The invention belongs to the technical field of sand washing, and in particular relates to a method and a device for washing and separating cross-flow sand and mud. Background technique [0002] Sand washing machines currently on the market such as Figure 18 As shown, the mud content of the finished product of this sand washing machine is too high and the quality is not good. The finished sand 5 of this type of sand washing machine contains a large amount of sludge, which can be divided into sand-attached mud, surface mud, and interstitial mud. The causes are as follows: [0003] Sand-attached mud: The raw sand becomes a fluid state with the washing of the water flow, so that the sand and mud are evenly distributed in the water body. Although the sludge in the sand gap is separated, the sludge still adheres to the sand due to the irregularity of the particles on the surface of the sand. The sludge particles will settle together with the sand particles...
