A hydrocyclone for mineral recovery

Abstract

This utility model relates to the field of hydrocyclone technology, specifically disclosing a hydrocyclone for mineral recovery, comprising: a mounting cover; a water inlet installed outside the mounting cover; and a wastewater outlet installed at the top of the mounting cover. This utility model, through the arrangement of a wastewater outlet, a hydrocyclone chamber, a mineral outlet, and a drain pipe, divides the internal space of the hydrocyclone into upper and lower hydrocyclone chambers by setting a guide plate. After minerals and water enter the hydrocyclone, under the action of the guide plate, the minerals are squeezed into the hydrocyclone chamber below the guide plate. Finally, these minerals sink along the inner wall of the hydrocyclone and are discharged from the mineral outlet. Furthermore, due to the presence of the guide plate, the flow space inside the hydrocyclone is restricted, resulting in a significant increase in the water rotation speed. This characteristic makes the separation effect between heavier minerals and water more obvious, thereby effectively improving the mineral recovery efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of hydrocyclone technology, specifically relating to a hydrocyclone for mineral recovery. Background Technology

[0002] Hydrocyclones for mineral recovery are devices used for mineral sorting and recovery. They are widely used in mining, metallurgy, chemical and other industries. They use centrifugal force to accelerate particle sedimentation and separation to achieve solid-liquid separation or classification. Hydrocyclones have a simple structure, no moving parts, low cost and high efficiency, and occupy an important position in the field of mineral processing.

[0003] When a conventional hydrocyclone is in operation, the inlet pressure is relatively high, and the mineral particles are of inconsistent size, causing the minerals entering the hydrocyclone to collide with each other. This prevents the minerals from being fully thrown to the edge of the hydrocyclone cylinder. When the hydrocyclone is in operation, the pressure at the front end of the wastewater outlet is relatively low compared to the inlet pressure. Minerals that cannot be thrown to the edge of the cylinder will be drawn into the wastewater outlet. Thus, conventional hydrocyclones used for mineral recovery can only recover 85%-90%. Utility Model Content

[0004] The purpose of this invention is to provide a hydrocyclone for mineral recovery, in order to solve the problem mentioned in the background art that, when using existing hydrocyclones, minerals that cannot be thrown to the edge of the cylinder are drawn into the wastewater outlet, affecting the recovery rate of mineral particles.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hydrocyclone for mineral recovery, comprising:

[0007] Install cover;

[0008] A water inlet, which is installed on the outside of the mounting cover;

[0009] Wastewater outlet, which is installed at the top of the mounting cover, and a vortex chamber is fixedly connected to the bottom of the mounting cover.

[0010] Preferably, a mineral outlet is fixedly connected to the bottom end of the cyclone chamber, a drain pipe is fixedly connected to the bottom end of the wastewater outlet, and a guide plate is fixedly connected to the bottom end of the drain pipe.

[0011] Preferably, the mounting cover and the vortex chamber are fixedly connected by bolts, and the vortex chamber has a conical structure.

[0012] Preferably, the guide plate has a conical shape, and a permeation groove is formed through the middle part of the guide plate.

[0013] Preferably, the middle part of the drain pipe has a permeation groove, and the drain pipe is welded to the bottom of the wastewater outlet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the design of a wastewater outlet, a cyclone chamber, a mineral outlet, and a drain pipe, divides the internal space of the hydrocyclone into upper and lower cyclone chambers by incorporating a guide plate. After minerals and water enter the hydrocyclone, the minerals are squeezed into the lower cyclone chamber by the guide plate. Due to their higher density, the minerals are forced to adhere to the inner wall of the hydrocyclone and are prevented from passing through the lower cyclone chamber into the wastewater outlet. Ultimately, these minerals sink along the inner wall of the hydrocyclone and are discharged from the mineral outlet. Furthermore, the presence of the guide plate restricts the flow space inside the hydrocyclone, significantly increasing the water rotation speed. This characteristic makes the separation of heavier minerals from water more effective, thereby significantly improving mineral recovery efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figures 1-3 As shown, a hydrocyclone for mineral recovery includes:

[0023] Install cover 1;

[0024] Water inlet 2, which is installed on the outside of the mounting cover 1;

[0025] Wastewater outlet 3 is installed at the top of mounting cover 1. A vortex chamber 4 is fixedly connected to the bottom of mounting cover 1. A mineral outlet 5 is fixedly connected to the bottom of vortex chamber 4. A drain pipe 6 is fixedly connected to the bottom of wastewater outlet 3. A guide plate 7 is fixedly connected to the bottom of drain pipe 6. Mounting cover 1 and vortex chamber 4 are fixedly connected by bolts. The vortex chamber 4 has a conical structure. The guide plate 7 has a conical shape. A permeation groove is opened through the middle part of the guide plate 7. A permeation groove is opened through the middle part of the drain pipe 6. The drain pipe 6 is welded to the bottom of wastewater outlet 3.

[0026] Specifically, the mineral-containing water swirling below the guide plate 7 has fine mineral particles and a low mineral concentration. When it is forced to swirl upwards to the bottom of the guide plate 7, the fine mineral particles are squeezed to the side of the swirling chamber 4 due to the swirling and high specific gravity, and then swirling down to the mineral outlet 5. This achieves secondary recovery of fine mineral particles and a highly efficient secondary recovery effect.

[0027] As can be seen from the above, by setting the guide plate 7, the internal space of the hydrocyclone can be divided into upper and lower hydrocyclone chambers. Under the guidance of the guide plate 7, the mineral water is directly squeezed into the hydrocyclone chamber below the guide plate 7. Because the specific gravity of minerals is greater than that of water, the minerals squeezed into the inner wall of the hydrocyclone chamber 4 cannot enter the wastewater outlet 3 through the hydrocyclone chamber below the guide plate 7. As a result, the minerals in the inner wall of the hydrocyclone chamber 4 sink to the mineral outlet 5 for discharge.
