The slurry formed by the slurry device falls downward into the chute 2, and flows along the chute for mineral processing. The bottom of the chute 2 is supported by a plurality of support rods 5. The adsorption blanket 3 is arranged at the bottom of the chute 2, and preferably, the hair length of the adsorption blanket 3 is 3-8 cm. A plurality of baffle frames 4 are evenly arranged in the chute 2.

[0026] The slurry device of the utility model includes a distribution trough 6, a guide trough 7, a pressure water tank 8, a spray pipe 9 and four water inlet pipes 10. Two water inlet pipes 10 and the spray pipe 9 are connected to the upper part of the silo 1. The spray pipe 9 penetrates the silo 1 and extends to the inside thereof; the distribution trough 6 and the guide trough 7 are respectively connected to the water inlet pipe 10. The cross section of the distribution trough 6 is formed by a combination of a rectangle and an isosceles trapezoid. The distribution trough 6 is connected to the bottom of the silo 1. The water inlet pipe 10 connected to the distribution trough 6 can further adjust the concentration of the slurry and can impact the slurry so that it quickly enters the guide trough 7 to avoid the slow flow of the slurry. The length range of the distribution trough 6 of the utility model is 2-3.5m, the width is 1.5-2.5m, the height is 30-50cm, and the side wall thickness of the distribution trough 6 is 12-16mm.

[0027] The guide trough 7 is arranged below the dividing trough 6 and connected to the bottom of the dividing trough 6. Several guide plates 11 are evenly arranged in the guide trough 7 to evenly divide the inside of the guide trough. The spacing between the guide plates 11 is 1 meter, and the thickness of the guide plates 11 is 10-12 mm. The outlet of the water inlet pipe 10 connected to the guide trough 7 is higher than the guide plate 11, and the water inlet is connected to the pressure water tank 8, which can flush the water pressurized by the pressure water tank 8 into the guide trough 7 to impact the slurry in the guide trough 7. The impacted slurry flows evenly into the chute through the guide plate 11.

[0028] Each water inlet pipe 10 and each spray pipe 9 is provided with a regulating valve 12 for controlling the amount of water in the water inlet pipe or the spray pipe.

[0029] The pressure water tank 8 has a pressure of not less than 1.5 MPa and a volume of 0.5-1 m³. The function of the pressure water tank 8 is to adjust the pressure and amount of the water outlet when the slurry concentration in the silo 1 is too high or too low, and the slurry flow rate in the chute 2 is too fast or too slow, so as to enable normal and stable production.

[0030] The length of the chute 2 of the utility model is 45-60m, the internal width is 1-3m, the side height is 30-50cm, the side wall thickness of the chute 2 is 12-16mm, the inclination angle of the chute 2 is 5-15°, and the volume of the silo 1 is 25-40m³.

[0031] The baffle frame 4 is a square with a side length of 1m. When the internal width of the chute is 3 meters, three baffle frames can be accommodated in the width direction. Figure 1 or Figure 3 As shown, when the internal width of the chute is 1m or 2m, two or one baffle frame can be accommodated in the width direction, and the baffle frame height is 5-6cm. When the internal width of the chute is 1m, the guide plate may not be required.

[0032] The specific structure inside the barrier plate frame 4 of the present invention is described in the following embodiments. Example 1

[0033] In each barrier frame 4 of the present invention, three barrier strips 13 are arranged in parallel along the inclined direction of the chute 2. Figure 3 and Figure 4 As shown, the barrier strip 13 and the bottom of the chute 2 are arranged vertically. Example 2

[0034] In each barrier frame 4 of the present invention, three barrier strips 13 are arranged in parallel along the inclined direction of the chute. Figure 1 and Figure 2 As shown, the barrier strip is arranged obliquely downward relative to the bottom of the chute 2, and the angle between the barrier strip and the bottom of the chute 2 is 45° or 60°. Example 3

[0035] like Figure 5 As shown, a plurality of grids 14 are evenly arranged in each blocking plate frame 4 .

[0036] The side edges of the barrier frame 4 and the barrier strips 13 are made of rice boards with a thickness of 3-8 mm.

[0037] The use principle of the utility model is as follows: the mineral material is sent into the silo 1, and the applicable range of the mineral particles of the utility model is 20-300 meshes. Water is injected into the silo 1 through the water inlet pipe 10 and the spray pipe 9 connected to the silo 1, so that the mineral material forms a slurry. At the same time, the concentration of the slurry can be controlled by adjusting the opening amount of the water inlet pipe 10, or adjusting the opening of the regulating valve 12 of the water inlet pipe 10 and the spray pipe 9. The formed slurry falls into the material separation trough 6, and then enters the chute 2 for ore dressing through the guide trough 7. The concentration of the slurry entering the chute 2 is: the water-material ratio is 1:2.5-4.5. The slurry entering the chute 2 flows downstream to the tail of the chute under the combined force of potential energy and water impact. The required minerals are precipitated into the adsorption blanket 3 under the reverse resistance of the barrier frame, and are accumulated as the required selected minerals.

[0038] According to the different specific gravity (density) of the ore, the chute is divided into four sections: calculated from the top of the chute, the first 12 meters are heavy ore sections; 12-24 meters are medium-heavy ore sections; 24-36 meters are medium-light ore sections; 36 meters to the exit are light ore sections. According to the different specific gravity, the ore with a specific gravity of more than 10 grams per cubic centimeter is defined as heavy ore; 10-7 grams is defined as medium-heavy ore; 4-7 grams is defined as medium-light ore; and less than 4 grams is defined as light ore.

[0039] The position and installation angle of the barrier strips 13 on the barrier plate frame 4 or the formed grids 14 generate reverse resistance to the flow of the slurry formed by the slurry device when it flows in the chute 2, so that the flow of the slurry is disturbed, the flow is slowed down and some minerals are precipitated. The adsorption blanket 3 then grabs the precipitated minerals to achieve mineral separation, and minerals of different weights will fall in sequence according to their different specific gravities during the flow process and be sucked into the adsorption blanket 3 at the bottom of the chute (such as the four mineral separation stages described above), thereby completing the mineral separation.

[0040] The utility model also includes a sedimentation tank 15 and a regeneration water tank 16. The sedimentation tank is connected to the bottom of the chute 2 through a connecting water pipe 17. The sedimentation tank is connected to the regeneration water tank 16 through a connecting water pipe 17. A filter screen 18 is provided on the connecting water pipe connecting the regeneration water tank 16 and the sedimentation tank 15. The regeneration water tank is connected to each water inlet pipe 10 or spray pipe 9 of the slurry device through the connecting water pipe. The pressure water tank 8 is also connected at the same time. The slag produced by the ore dressing is removed after precipitation in the sedimentation tank and sent to the solid treatment field for treatment; the filtrate flows to the regeneration water tank and can be returned to the slurry device through the connecting water pipe 17 for slurry formation and use.

[0041] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field should fall within the protection scope of the present invention. The technical contents for which protection is sought in the present invention have been fully recorded in the technical requirements.
