Embodiment Construction
[0021] Such as figure 1 and figure 2 A step-type primary purification device for high-concentration iron-shaving waste liquid is shown, including: a vertical wall 1 at the entrance end, a stepped platform 2 and a vertical wall 3 at the exit end;
[0022] The stepped platform 2 is a 4-level step structure, from the entrance end to the exit end, in order, the first level of steps 4, the second level of steps 5, the third level of steps 6 and the fourth level of steps 7;
[0023] The entrance vertical wall 1 is vertically arranged at the beginning end of the first step 4, and has a waste liquid inflow hole 1.1 inside;
[0024] The waste liquid inflow hole 1.1 is an inclined through hole inclined downward;
[0025] The upper end surface of the first step 4 is provided with a sloped boss 4.1 whose top is connected with the output port of the waste liquid inflow hole 1.1;
[0026] Among them, the flat surface parts of the first step 4, the second step 5, the third step 6 and the...

The invention discloses a stair type primary purification device for high-concentration cutting waste liquid with iron. The stair type primary purification device for the high-concentration cutting waste liquid with the iron comprises an inlet end vertical wall, a stair platform and an outlet end vertical wall; the stair platform is of a four-stage stair structure and sequentially comprises a first-stage stair, a second-stage stair, a third-staged stair and a four-stage stair from the inlet end to the outlet end; flow buffering protrusions with triangular cross sections are arranged on the surface of each stage of stair, and meanwhile an electromagnet layer is arranged below each surface; and under the flow buffering effect of the flow buffering protrusions, primary distinguishing of low-concentration waste liquid and high-concentration waste liquid is achieved in cooperation of the controllable adsorbing effect of the electromagnet layers.
Description
technical field [0001] The invention relates to the field of liquid purification, in particular to a step-type primary purification device for high-concentration strip iron cutting waste liquid. Background technique [0002] At present, for the liquid with high content of iron shavings, the method of depositing is directly adopted to remove the internal iron shavings, but this is done directly in the sedimentation tank, the time period is long, and the water needs to be drained every time It is time-consuming and labor-intensive to recycle iron cutting. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a method that can realize primary purification during the liquid flow process, and at the same time directly distinguish high-concentration deposition liquid and low-concentration deposition liquid, which is convenient for the next supplementary purification treatment. [0004] In order to achieve the above purpose, it...
