Description

Technical Field

[0001] This utility model belongs to the field of water for magnetic separators and relates to a water distribution device for magnetic separators. Background Technology

[0002] Magnetic separators are primarily used for magnetite beneficiation and are widely applied in mines across China. Magnetic separators are mainly equipped with dispersing water and rinsing water. The dispersing water's main purpose is to disperse the minerals entering the magnetic separator before separation, creating better conditions for subsequent separation. The rinsing water is mainly used to rinse the surface of the magnetic rollers, and the selected concentrate is then flushed into the concentrate box, ultimately completing the magnetic separation process.

[0003] The water distribution for the washing water and the flushing water of the magnetic separator is generally a Φ100mm main water pipe, which is controlled by a valve. The main water pipe is then divided into two branch pipes laterally, one leading to the flushing water and the other to the washing water.

[0004] However, during daily production, the water quality or debris may clog the water pipes, resulting in reduced flushing water volume and blocked flushing pipes, which can lead to incomplete cleaning of the magnetic rollers. This necessitates frequent stops for inspection and unblocking. Utility Model Content

[0005] This application provides a water distribution device for a magnetic separator, which can effectively increase the washing water volume of the magnetic separator and at the same time reduce the intensity of manual maintenance.

[0006] To achieve the above technical objectives, the technical solution adopted in this application is a water distribution device for a magnetic separator, comprising: a main water pipe, a flushing water branch pipe at one end in the axial direction, and a plug at the other end in the axial direction; an inlet water branch pipe on one side in the radial direction, and a flushing water branch pipe on the other side in the radial direction; wherein, the flushing water branch pipe is connected to the flushing water pipe, and a flushing water branch pipe ball valve is installed in the flushing water branch pipe; the flushing water branch pipe is connected to the flushing water pipe, and a flushing water branch pipe ball valve is installed in the flushing water branch pipe; and the flushing water pipe is provided with multiple water outlets.

[0007] As an improved technical solution of this application, there are two flushing water branch pipes, the inner diameter of each flushing water branch pipe is the same as the inner diameter of the rinsing water branch pipe, and each flushing water branch pipe is connected to a flushing water pipe.

[0008] As an improved technical solution of this application, the inner diameter of the flushing water branch pipe is half the inner diameter of the main water pipe.

[0009] As an improved technical solution of this application, the flushing water pipe is placed on the flushing water tank, and two flushing water pipes are arranged side by side. The water outlets on the flushing water pipes face downwards, and the water outlets on each flushing water pipe are radially offset from the water outlets of the other flushing water pipe.

[0010] As an improved technical solution of this application, the flushing water pipe is connected to the flushing water branch pipe through a steel wire composite flexible hose; the flushing water pipe is located on the flushing water tank of the magnetic separator.

[0011] As an improved technical solution of this application, a drain valve is provided at the end of the flushing water pipe. Beneficial effects

[0012] After the device is put into operation, two flushing water branch pipes and one rinsing water branch pipe are set up, which not only ensures the amount of rinsing water used, but also increases the amount of flushing water used.

[0013] After using this device, the washing water volume of the magnetic separator was further increased, the washing effect of the magnetic roller was improved, and the blockage of the water pipe was also improved to a certain extent. Furthermore, by adding a flushing water drain valve and a main water pipe plug, daily unclogging is also more convenient, reducing the intensity of manual maintenance. Attached Figure Description

[0017] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figure 1As shown, a water distribution device for a magnetic separator includes: a main water pipe 1, a flushing water branch pipe 2 at one end in the axial direction, and a plug 6 at the other end in the axial direction; an inlet water branch pipe on one side in the radial direction, and a flushing water branch pipe 4 on the other side in the radial direction. The inlet water branch pipe and the flushing water branch pipe 4 are respectively positioned in the axial direction of the main water pipe 1, and the flushing water branch pipe 2 is positioned in the radial direction of the main water pipe 1. By changing the water flow direction, the flushing water volume is increased while simultaneously meeting the flushing water volume requirements. Furthermore, the plug 6 at the other end in the radial direction of the main water pipe 1 facilitates cleaning of the main water pipe 1 during maintenance.

[0019] The flushing water branch pipe 2 is connected to the flushing water pipe 7, and a flushing water branch pipe ball valve 3 is installed in the flushing water branch pipe 2; the flushing water branch pipe 4 is connected to the flushing water pipe 8, and a flushing water branch pipe ball valve 5 is installed in the flushing water branch pipe 4. The function of the flushing water branch pipe ball valve 5 is to control the opening and closing of the flushing water branch pipe 4.

[0020] The flushing water pipe 8 is equipped with multiple water outlets to increase the flow rate of flushing water.

[0021] As an improved technical solution of this application, there are two flushing water branch pipes 4, each with the same inner diameter as the flushing water branch pipe 2, and each flushing water branch pipe 4 is connected to a flushing water pipe 8. The purpose is to increase the water output of the flushing water branch pipes 4.

[0022] As an improved technical solution of this application, the inner diameter of the flushing water branch pipe 4 is half the inner diameter of the main water pipe 1. The purpose is to increase the outlet water pressure of the flushing water branch pipe 4 and increase the flushing water output.

[0023] As an improved technical solution of this application, the outlets of the two rinsing water pipes 8 are arranged facing the rinsing water tank 9, and are spaced apart in the axial direction of the rinsing water pipes 8, and are staggered in the radial direction, without overlapping. That is, the rinsing water pipes 8 are placed on the rinsing water tank 9, the two rinsing water pipes 8 are arranged side by side, the outlets of the rinsing water pipes 8 face downwards, and the outlets of each rinsing water pipe 8 are radially staggered from the outlets of the other rinsing water pipe 8. The purpose of this arrangement is to ensure that after the rinsing water enters the rinsing water tank 9, the water level in the rinsing water tank 9 rises evenly and stably, and the overflowing water flows evenly to the magnetic roller surface, making the magnetic roller surface rinsed more thoroughly.

[0024] As an improved technical solution of this application, the flushing water pipe 8 is connected to the flushing water branch pipe 4 via a steel wire composite flexible hose 10; the flushing water pipe 8 is located on the flushing water tank 9 of the magnetic separator. The purpose is to use the steel wire composite flexible hose 10 for flexible connection, which facilitates later maintenance and on-site adjustment of the position of the flushing water pipe 8.

[0025] As an improved technical solution of this application, a drain valve 11 is provided at the end of the flushing water pipe 8. The purpose is to facilitate the later unblocking of the flushing water pipe; after opening the drain valve 11, debris inside the flushing water pipe 8 can be removed. Example

[0026] A water distribution device for a magnetic separator includes designing and manufacturing a water distribution device, which is installed on the Φ100mm main water pipe 1 of the magnetic separator.

[0027] Traditional magnetic separators use a single flushing water pipe and a single rinsing water pipe for water distribution. This design features two Φ50mm rinsing water branch pipes 4 leading to the rinsing water direction, connected to the rinsing water pipe 8; and a single Φ50mm flushing water branch pipe 2 leading to the flushing water direction, connected to the flushing water pipe 7. This significantly increases the water volume in the flushing water direction, ensuring effective rinsing of the magnetic rollers.

[0028] The two Φ50mm flushing water pipes 8 have three Φ25mm flushing water outlets 12. This is mainly because if there are too many small flushing water outlets 12, they are prone to clogging and the flow rate is low. By having only three outlets and enlarging the flushing water holes to Φ25mm, a large water volume can be guaranteed and clogging is less likely. The staggered arrangement of the outlets of the two flushing water pipes 8 is mainly to allow the overflowing water to be flushed more evenly onto the surface of the magnetic roller.

[0029] A water distribution device is designed to connect the Φ100mm main water pipe of the magnetic separator to the branch points of the flushing and rinsing water.

[0030] The lower part of the water inlet branch pipe of the water distribution device is a Φ100mm flange, which is connected to the valve of the main water pipe 1.

[0031] One side of the main water pipe in the axial direction is a Φ50mm flushing branch pipe 2, which is controlled by a Φ50mm copper ball valve (flushing branch pipe ball valve 3). On the other side of the main water pipe 1 in the axial direction, a plug 6 is made for use when inspecting and clearing internal debris. This plug is closed during normal use.

[0032] One side of the main water pipe 1 in the radial direction consists of two Φ50mm flushing water branch pipes 4, controlled by Φ50mm copper ball valves (flushing water branch pipe ball valves 5). Figure 2As shown, two Φ50mm flushing water pipes 8 are connected to two Φ50mm flushing water branch pipes 4 of the water distribution device via steel wire composite hoses 10, and are situated on the flushing water tank 9. Each of the two Φ50mm flushing water pipes 8 has three Φ25mm water outlets (flushing water outlets 12) at its bottom, spaced apart axially and staggered radially, with the outlets of the two flushing water pipes 8 not overlapping in the radial direction. This arrangement aims to ensure that the water level rises evenly in the flushing water tank 9 (tank), and that the overflowing water flows evenly to the magnetic roller surface, allowing for a more thorough flushing of the magnetic roller surface.

[0033] Both Φ50mm flushing water pipes 8 are equipped with drain valves 11 at their ends for easy dredging and maintenance later.
