[0026] Embodiment 2:
[0027] The following further introduces the solution of the first embodiment in combination with the specific working method, as described below.
[0028] As attached Figure 1 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the bottom end surfaces of the initial treatment box 1 and the temporary storage box 10 are both inclined structures, and the inclination direction is inclined to the lower right. The bottom end surfaces of the initial treatment box 1 and the temporary storage box 10 inclined to the lower right can help the solution inside the initial treatment box 1 and the temporary storage box 10 to flow toward the connecting hole 16 and the water outlet 11, so that the internal solution of the initial treatment box 1 and the temporary storage box 10 can all flow out without remaining inside the initial treatment box 1 and the temporary storage box 10; the interior of the feed pipe 3 is provided with staggered downwardly inclined guide plates 5, and the feed pipe 3 and the filter box 2 are connected. The guide plates 5, which are located in the same vertical direction and are staggered, can make the oil-water mixture entering the feed pipe 3 undergo turning and collision during the falling process, which can cause tiny oil particles to aggregate into larger oil particles. The oil in the oil-water mixture will float up in the static box 6 due to the density difference, thereby accelerating the oil-water separation process; the overflow port 8 is located above the oil collection box 9, and the horizontal cross-sectional size at the large end of the oil collection box 9 is equal to the horizontal cross-sectional size of the temporary storage box 10. The large end of the oil collection box 9 can be embedded in the interior of the temporary storage box 10, and the oil flowing out of the overflow port 8 can directly flow into the interior of the oil collection box 9.
[0029] As attached Figure 1 , 4As shown in Figure 5, as a preferred embodiment, on the basis of the above-mentioned method, further, the interior of the initial treatment box 1 and the temporary storage box 10 are respectively connected with a support plate 19, and a limiting hole 17 is opened inside the support plate 19, and the limiting hole 17 will not block the flow of the solution in the initial treatment box 1 and the temporary storage box 10; the filter box 2 and the oil collection box 9 are both "T"-shaped structures, and the horizontal cross-sectional area of the small end of the filter box 2 and the oil collection box 9 is smaller than the horizontal cross-sectional area of the limiting hole 17, and the filter box 2 and the oil collection box 9 are provided with symmetrically distributed handles 18, and the filter box 2 and the oil collection box 9 can be embedded in the limiting hole 17 on the support plate 19 for fixation, and the symmetrically distributed handles 18 can make the filter box 2 and the oil collection box 9 evenly stressed, which is convenient for the installation and disassembly of the filter box 2 and the oil collection box 9.
[0030] As attached Figure 1-3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the baffle column 7 is a "T"-shaped structure, and the outer diameter of the small end of the baffle column 7 is equal to the inner diameter of the mounting groove 14, and a rubber pad 20 is arranged on the outside of the small end of the baffle column 7. The baffle column 7 can be embedded in the interior of the mounting groove 14, and when the baffle column 7 is rotated 90 degrees so that the position of the through hole 13 on the baffle column 7 is perpendicular to the overflow port 8 and the water outlet 12, the passage of the solution can be blocked, which has a baffle effect, and the oil and water in the oil-water mixture can be separated more thoroughly by static separation. The rubber pad 20 can make the baffle column 7 fit more tightly.
[0031] Working principle: First, fit the filter box 2 and the oil collection box 9 into the limiting holes 17 on the internal support plates 19 of the initial treatment box 1 and the temporary storage box 10 respectively, then fit the cover plate 4 into the initial treatment box 1, the static box 6 and the temporary storage box 10 respectively, fit the baffle column 7 into the installation groove 14, and the rubber pad 20 can make the baffle column 7 fit more tightly, so that the position of the through hole 13 on the baffle column 7 is perpendicular to the overflow port 8 and the water outlet 12, and pour the oil-water mixture into the feed pipe 3. The staggered drainage plates 5 can make the oil-water mixture entering the feed pipe 3 be turned and collided during the falling process, which can cause tiny oil particles to gather into larger oil particles. The oil-water mixture will filter out larger impurities through the filter box 2, and then pass through The connecting hole 16 will flow into the static box 6, and the oil in the oil-water mixture will float up in the static box 6 due to the density difference. The baffle 15 in the static box 6 will further cause the oil-water mixture to collide, which can accelerate the oil-water separation process. After the separation process is completed, the baffle column 7 can be rotated 90 degrees to make the position of the through hole 13 on the baffle column 7 correspond to the overflow port 8 and the water outlet 12. The separated oil layer can flow from the overflow port 8 into the oil collection box 9 in the temporary storage box 10, and the water layer can flow from the water outlet 12 into the temporary storage box 10, and finally can flow out from the water outlet 11, thereby realizing further separation of oil and water. After the separation process is completed, the filter box 2 and the oil collection box 9 can be lifted up by the handle 18 to pour out the impurities and oil inside.
