[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1: As Figure 1 As shown, an ultrafine powder water medium sorting device includes a circular vertical plate 2, a top plate 1 slidably connected to the top of the inner wall of the circular vertical plate 2, a bottom plate 3 fixedly connected to the bottom of the inner wall of the circular vertical plate 2, a water inlet pipe 7 horizontally penetrating the interior of the circular vertical plate 2, a first diverter assembly 4 fixedly connected to one end of the water inlet pipe 7, and multiple sets of first guide holes 13 symmetrically distributed about the vertical center line of the top plate 1 on the surface of the first diverter assembly 4.

[0025] like Figure 1 As shown, the top end of the first splitter assembly 4 is connected to the bottom end of the top plate 1. A motor is installed at the top end of the top plate 1. The output end of the motor is electrically connected to a lead screw. The lead screw passes through the top plate 1, and a fan blade 14 is fixedly connected to the rod surface inside the first splitter assembly 4.

[0026] This scheme adopts Stokes' sinking velocity formula, which was derived theoretically by American physicist Stokes in 1850 to calculate the sinking velocity (w) of a sphere in laminar flow.

[0027] The formula is as follows: w = [2(ρS - ρ)gr²] / 9μ Where: ρS is the particle density; ρ is the density of water; μ is the fluid viscosity; r is the particle radius; g is the acceleration due to gravity. This formula was obtained under ideal laboratory conditions: still water, constant temperature of 20℃, constant viscosity of the medium, spherical particles, uniform density, smooth surfaces, and no particle collisions. Of course, this differs greatly from actual conditions in nature, as still water conditions are almost nonexistent in nature. Many factors affect the settling velocity of clastic particles, mainly including particle shape, water quality, and sediment content. Therefore, most settling velocity formulas are empirical. Although they differ from actual conditions, this formula still has theoretical significance. It shows that the settling velocity of clastic particles is proportional to the square of the particle diameter. This can be used to explain the particle size distribution in sedimentary basins and the mixing of particles of different shapes, densities, and sizes. It is also the theoretical basis for settling velocity analysis in the mechanical analysis of particles (0.1–0.14 mm).

[0028] Stokes formula refers to a formula used to calculate the settling velocity of solid particles in a liquid depends on the size of the particles and the properties of the liquid. For the analysis of fine soil particles that cannot be sieved, Stokes law is commonly used, that is, different soil particles are classified according to the speed of their settling in water. The particles in the vacuum are not subject to any resistance, only the action of gravity, and the particles in the water are subject to the action of viscous resistance in addition to the action of gravity.

[0029] Specifically, in this design, the motor type is Y80M1-2, the motor is turned on, the fan blade 14 is rotated in the inside of the first flow divider assembly 4, the formation of the vortex is promoted, the settling of various fine powder particles in the centrifugal field, and the fine powder particles realize the separation of particles according to specific gravity. Because fine powder particles of different densities and different particle sizes have different settling characteristics in the centrifugal field, fine powder particles with light specific gravity and part of fine powder particles with large density enter the upward inner rotating flow, flow into the inner cavity of the circular vertical plate 2 through the first flow guide hole 13, and the particles with large density and part of the coarse particles with small density are moved to the bottom of the first flow divider assembly 4 along the outer rotating flow of the first flow divider assembly 4. The discharge is carried out, and the first process of flow screening is carried out.

[0030] As shown in Figure 4 , the first flow divider assembly 4 comprises an upper pipe 401, a rotating cavity 402 and a lower pipe 403. The upper pipe 401 is a telescopic circular pipe. The upper pipe 401 and the lower pipe 403 are fixedly connected to the upper and lower end faces of the rotating cavity 402 respectively, and the inside of the upper pipe 401 is communicated with the lower pipe 403 through the rotating cavity 402.

[0031] As shown in Figure 5 , the inner wall of the first flow divider assembly 4 is fixedly connected with an annular base 19. The annular base 19 is located at the inner bottom end of the upper pipe 401. The inner wall of the annular base 19 is slidably connected with a lead screw.

[0032] As shown in Figure 2 , the inner wall of the circular vertical plate 2 is slidably connected with a flow guide cavity 8. The flow guide cavity 8 is conical in shape. A plurality of flow guide plates 9 are fixedly connected to one side of the flow guide cavity 8 facing the first flow divider assembly 4.

[0033] When the vortex enters the inside of the circular vertical plate 2, the impact of the flow guide plate 9 promotes the rotation of the flow guide cavity 8 in the direction of rotation of the vortex, and the vortex is introduced into the inside of the second flow divider 5. Because of the settling of various fine powder particles in the centrifugal field, and according to the Stokes settling velocity formula, which shows that the settling velocity of the debris particles is proportional to the square of the particle diameter, the phenomenon of the settlement of fine powder particles is formed to be layered up and down and horizontally.

[0034] As shown in Figure 1As shown, the surface of the first shunt assembly 4 is connected with two groups of annular shaft rings 15 from top to bottom, respectively, and the annular shaft rings 15 are fixedly connected with the surface of the first shunt assembly 4, the bottom end of one group of annular shaft rings 15 is fixedly connected with the second shunt 5, and the surface of the other group of annular shaft rings 15 is fixedly connected with the third shunt assembly 6.

[0035] As shown in the figure, Figure 3 The third shunt assembly 6 comprises an outer supporting shunt plate 601 and an inner supporting shunt plate 602, the outer supporting shunt plate 601 is arranged in an inverted V shape, the inner supporting shunt plate 602 is arranged in a V shape, the outer supporting shunt plate 601 and the inner supporting shunt plate 602 are fixedly connected, and the surface of the second shunt 5 and the third shunt assembly 6 is provided with a plurality of second flow guide holes 18.

[0036] When various fine powder particles enter the second shunt 5 and the third shunt assembly 6, most of the particles entering the inside of the second shunt 5 and the third shunt assembly 6 are limited in range due to the blockage of the inner wall of the second shunt 5 and the third shunt assembly 6, but the upper and lower ends of the second shunt 5 and the third shunt assembly 6 are through, and the surface is provided with second flow guide holes 18, which cannot block the fine powder particles for shunting, so that fine powder particles of different sizes flow to the corresponding discharge port 17 for discharge.

[0037] As shown in the figure, Figure 3 A plurality of discharge ports 17 vertically penetrate the inside of the bottom plate 3, and a baffle 16 is arranged between the plurality of discharge ports 17, the bottom end of the baffle 16 is fixedly connected to the top end of the top plate 1, and the position of the baffle 16 corresponds to the bottom end of the second shunt 5 and the third shunt assembly 6.

[0038] Various fine powder particles rotate in water following the turbine, and the baffle 16 prevents various fine powder particles from moving to the edge of the bottom plate 3 due to inertia and the blockage of the bottom plate 3 after sorting, which ultimately cannot cause water quality sorting.

[0039] Example 2: As shown in the figure, Figure 2 The top end of the flow guide cavity 8 is provided with a positioning hole 12, the bottom end of the top plate 1 is provided with a fixed rod 20, and the positioning hole 12 and the fixed rod 20 correspond in position, the top end of the top plate 1 is provided with a rectangular groove 10, the rectangular groove 10 is provided with a rectangular block 11, and the side wall of the rectangular block 11 is hinged to the top end of the top plate 1.

[0040] After water quality sorting, a lot of fine powder particles are adhered to the inner wall of the equipment, at this time, the top plate 1 is pressed down, the fixed rod 20 is inserted into the positioning hole 12, the flow guide cavity 8 is fixed in position, the water in the equipment is stirred by the motor, when the water is left in the inner cavity of the circular vertical plate 2, the water quality is vibrated by impacting the flow guide plate 9, and the inside of the equipment is cleaned.
