[0002] The hindered settler is a hydraulic classification device that uses water as the medium and uses the rising medium flow for classification. It has the characteristics of simple structure, reliable classification, and large processing capacity. It is often used in silica sand beneficiation and classification operations. In order to ensure that the medium flow rate is uniform on the cross section of the hindered settler, the water must consume kinetic energy before entering the classification cylinder to reduce the impact on the classification effect. Therefore, it is necessary to set a water tank with the same radius as the classification cylinder and a suitable volume at the bottom of the hindered settler for buffering.

[0003] The upper part of the existing box is generally a porous plate, and is connected to the grading cylinder to form a uniform ascending medium flow. However, the bottom plate of the existing box is usually flat. On the one hand, the bottom plate cannot gather the debris in the box, and the debris in the corner is difficult to clean, making the cleaning of the box difficult; on the other hand, the debris may cause the porous plate on the upper part to be blocked, resulting in uneven flow rate of the ascending water flow.

[0031] The upper part of the existing box is generally a porous plate, and is connected to the grading cylinder to form a uniform ascending medium flow. However, the bottom plate of the existing box is usually flat. On the one hand, the bottom plate cannot gather the debris in the box, and the debris in the corner is difficult to clean, making the cleaning of the box difficult; on the other hand, the debris may cause the porous plate on the upper part to be blocked, resulting in uneven flow rate of the ascending water flow.

[0032] Based on this, the utility model proposes a water supply device. In order to facilitate the cleaning of impurities in the container, the bottom plate of the container is set to a shape with a decreasing cross-sectional area, and the cross-sectional area decreases from one end close to the cylinder to the end far from the cylinder, so that the debris can slide to the bottom of the bottom plate under the action of gravity, avoiding the problem of accumulation in the corners that is difficult to clean, thereby improving the stability of the rising medium flow and improving the classification efficiency.

[0033] like Figure 1 - Figure 4 As shown, the water supply device cooperates with the hindered settler, the hindered settler includes a cylinder for mineral classification, and the water supply device includes:

[0034] The container 100 is arranged on the side of the cylinder body facing the ground, and a water storage cavity connected to the cylinder body is formed inside the container 100. The container 100 includes a bottom plate 110 arranged away from the cylinder body, and the cross-sectional area of ​​the bottom plate 110 decreases from one end close to the cylinder body to the end away from the cylinder body.

[0035] The porous cover plate 200 is fixedly provided on the side of the container 100 facing the cylinder, and the porous cover plate 200 is provided with mutually independent water holes 210 and discharge ports 220, and the water holes 210 are connected to the water storage cavity, and the discharge ports 220 are not connected to the water storage cavity; and

[0036] The water supply port 121 is disposed on the side wall of the container 100 and is used to provide a circulating rising water flow into the water storage cavity.

[0037] In the technical solution adopted in this embodiment, in order to provide a circulating ascending water flow to the cylinder of the hindered settler, a water supply port 121 is provided on the side wall of the container 100, which can provide a circulating ascending water flow to the water storage chamber and transport it to the cylinder of the hindered settler. The minerals are separated under the rotational motion of the ascending water flow in the cylinder, and the separated mineral mixture will pass through the overflow trough on the hindered settler and enter the porous cover plate 200. The minerals with higher specific gravity will fall into the discharge port 220 and then be discharged, while the minerals with lower specific gravity or impurities will enter the water storage chamber inside the container 100 through the permeable hole 210. The debris or mineral particles with lower specific gravity will gather in the water storage chamber or block the permeable plate, resulting in uneven flow rate of the ascending medium, thereby affecting the classification effect of the minerals. In this solution, in order to gather the debris in the water storage chamber for easy cleaning, the bottom plate 110 of the container 100 is set to a shape with a decreasing cross-sectional area, and the cross-sectional area decreases from one end close to the cylinder to the end far from the cylinder, so that the debris can slide to the bottom of the bottom plate 110 under the action of gravity, avoiding the problem of accumulation in the corners and being difficult to clean, thereby improving the stability of the rising medium flow and improving the classification efficiency.

[0038] Specifically, the shape of the bottom plate 110 is not specifically limited, as long as the cross-sectional area changes and is conducive to the accumulation and discharge of debris. For example, the bottom plate 110 can be funnel-shaped or conical. Preferably, the radius of the container 100 is the same as the radius of the cylinder, so that the porous cover plate 200 is covered on the top of the container 100 to facilitate the connection with the cylinder. In this embodiment, the shapes of the water permeable holes 210 and the discharge port 220 are not specifically limited, and can be circular or square. It should be noted that the number and position of the water supply port 121 are not specifically limited. Preferably, two water supply ports 121 are provided on the side wall of the container 100, and the water inlet directions of the two water supply ports 121 are different, one of which can be fed in clockwise and the other in counterclockwise, so that the water flow can form a circulating medium flow in the water storage cavity and rise through the water permeable holes 210 and be transported into the cylinder. In addition, a water inlet pipe may be provided near the center of the porous cover plate 200, and the water inlet pipe extends into the cylinder, which can increase the impact water pressure.

[0039] Alternatively, if Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the bottom plate 110 is a conical plate, and the bottom design of the conical plate makes it easier for debris to gather. Due to the effect of gravity, debris will naturally gather at the bottom of the conical plate to form a concentrated area. This makes cleaning more convenient. Only by regularly cleaning the bottom of the conical plate can the water storage cavity be kept clean, so that the rising water flow in the cylinder of the obstructed settler is more stable. The traditional flat bottom plate 110 is difficult to clean due to the uniform distribution of debris, and it is easy to cause disturbance of the rising water flow.

[0040] Alternatively, if Figure 1 and Figure 2 As shown, in one embodiment of the utility model, in order to facilitate the separation of the mineral separated from the cylinder and the medium, the water supply device also includes a discharge pipe 300, so that after the mineral is separated from the medium, it can be smoothly discharged through the discharge pipe 300. Preferably, the discharge pipe 300 is arranged through the water storage cavity, and one end of the discharge pipe 300 is connected to the discharge port 220, and the other end of the discharge pipe 300 extends to the outside of the bottom plate 110, so that it can be conveniently connected to the external mineral collection device. In this way, after separation, the mineral can directly enter the collection device through the discharge pipe 300, avoiding the cumbersome operation of the intermediate link and improving the work efficiency. In another embodiment of the utility model, preferably, one end of the discharge pipe 300 is arranged at the center of the porous cover plate 200, and the other end of the discharge pipe 300 is arranged through the center of the bottom plate 110, so that the mineral can flow smoothly in the discharge pipe 300.

[0041] Alternatively, if Figure 1As shown, in one embodiment of the utility model, in order to conveniently discharge the debris in the water storage chamber in time, the water supply device further includes a drainage pipe 400, and a stop valve is also provided on the drainage pipe 400, which is used to open or close the channel in the drainage pipe 400. The drainage pipe 400 is arranged on the bottom plate 110 and close to the discharge pipe 300. The debris will gather at the cone tip under the action of gravity. Since the drainage pipe 400 is close to the cone tip of the conical bottom plate 110, after the drainage pipe 400 is opened, the debris will be smoothly discharged through the drainage pipe 400.

[0042] Alternatively, if Figure 2 and Figure 3 As shown, in one embodiment of the utility model, the porous cover plate 200 is a conical concave plate, and the discharge port 220 is arranged at the center of the porous cover plate 200. This design is conducive to the smooth discharge of minerals. At the same time, the discharge port 220 is arranged at the center of the porous cover plate 200, so that the minerals can naturally gather to the discharge port 220 under the action of gravity, thereby increasing the discharge speed, making the mineral processing process smoother, reducing the operating resistance of the obstructed settler, and increasing the service life.

[0043] Alternatively, if Figure 3 and Figure 4 As shown, in one embodiment of the utility model, a plurality of water-permeable holes 210 are provided through the porous cover plate 200, and the plurality of water-permeable holes 210 are evenly arranged radially along the radial direction of the porous cover plate 200, so that the water flow can be evenly and steadily transported upward from the water storage chamber, so that the subsequent classification effect is better. The provision of multiple water-permeable holes 210 increases the outlet of the water flow, helps to disperse the impact force of the water flow, and allows water molecules to rise slowly and steadily. In addition, the radially arranged water-permeable holes 210 can ensure the uniform distribution of the water flow. Due to the reasonable design of the pore size and the hole spacing, the water flow can be evenly transported toward the cylinder, avoiding fluctuations caused by uneven water flow.

[0044] Optionally, in an embodiment of the utility model, the container 100 is mainly composed of two parts: a side enclosure 120 and a bottom plate 110. The side enclosure 120 is provided with a first end and a second end that are arranged opposite to each other, and the two ends are connected to form a complete closed loop. This design allows the side enclosure 120 and the bottom plate 110 to jointly form a spacious water storage cavity, which is convenient for storing water flow. Preferably, the container 100 is barrel-shaped, and two water supply ports 121 are provided at both ends of one of the diameter directions of the side enclosure 120, and the water inlet directions of the two water supply ports 121 are opposite, so that a circulating medium flow is formed in the water storage cavity.

[0045] Alternatively, if Figure 1 and Figure 3As shown, in one embodiment of the utility model, a cleaning port 123 connected to the water storage chamber is provided on the side wall 120, and an opening and closing door is provided at the cleaning port 123, and the opening and closing door is used to open or close the cleaning port 123. It should be noted that in order to ensure the sealing of the cleaning port 123, a rubber gasket is used to seal the edge of the cleaning port 123. When it is necessary to clean the water storage chamber, it is only necessary to open the cleaning port 123 and the drainage pipe 400, and use a water pipe to flush water from the cleaning port 123 into the water storage chamber, and the debris in the water storage chamber can be discharged from the drainage pipe 400, which is more convenient and quick, and the cleaning effect is better.

[0046] Alternatively, if Figure 1 As shown, in one embodiment of the utility model, in order to improve the support strength of the container 100, the water supply device also includes a support member 500. It can be understood that the support member 500 is arranged on the side of the bottom plate 110 away from the porous cover plate 200, and the support member 500 is arranged in contact with the outer wall of the bottom plate 110. Preferably, the support member 500 includes a radial support frame connected to the discharge pipe 300 and a circular support frame that is concentric with the container 100. The radial support frame is connected to the circular support frame at the edge of the bottom plate 110 and the side 120 to form a mesh support structure to increase the support force on the bottom plate 110. In addition, the mesh support structure can disperse the pressure of the bottom plate 110, strengthen the support at the stress concentration point, and improve the compressive strength of the bottom plate 110.
