Description

Technical Field

[0001] This utility model relates to the field of metal beneficiation, and in particular to a magnetic separation column discharge and slag removal device. Background Technology

[0002] Magnetic separation columns are key equipment in the production of magnetic iron concentrate because they have the advantages of good classification and separation effect, high production efficiency, and saving materials and costs. They are widely used in magnetic mineral beneficiation and other applications. However, if the feed contains a large number of iron explosive fuses wrapped in rubber and other debris, it can easily cause equipment and pipeline blockage, affecting normal production in the workshop. Utility Model Content

[0003] In view of this, the present invention aims to provide a magnetic separation column discharge and slag removal device to solve the problems in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] This utility model proposes a magnetic separator discharge and slag removal device, including a stabilizing chamber, a feed pipe connected to the stabilizing chamber, a slag removal trough that is inclined and fixedly installed on the upper part of the side wall of the stabilizing chamber, and a slag-separating screen that is fixedly installed at the top opening of the slag removal trough. The end of the slag removal trough away from the stabilizing chamber is inclined downward, and the material enters the slag removal trough from the stabilizing chamber and flows along its inclination.

[0006] The bottom of the slag cleaning tank is connected to a connecting pipe, and one end of the connecting pipe is connected to the connecting groove.

[0007] Furthermore, the slag-separating mesh includes vertical rods and horizontal rods. Multiple vertical rods are spaced apart, and their two ends are fixedly connected to the side walls of the slag-cleaning trough. Multiple horizontal rods are fixedly arranged at intervals on the bottom surface of each vertical rod.

[0010] Furthermore, the feed pipe is connected to a lower position on the side wall of the flow stabilizing chamber.

[0011] Furthermore, a drain outlet is provided at the lower position of the side wall of the flow stabilizing chamber.

[0012] Furthermore, a slag discharge trough is fixedly provided on the end of the slag cleaning trough away from the flow stabilizing chamber.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] In this invention, the slag-blocking mesh at the top opening effectively intercepts non-magnetic impurities such as rubber, fiber, and large pieces of waste rock, preventing them from entering the subsequent sorting process, reducing the risk of magnetic column blockage, balancing the feed pressure fluctuations in the flow stabilizing chamber, ensuring that the material flows evenly into the slag-cleaning trough, and preventing the slag-blocking mesh from overloading or breaking due to sudden changes in flow rate.

[0015] Large particles are removed in advance by physical interception, which avoids wear on the magnetic separation column sorting medium and extends the equipment life. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0025] The following will refer to the appendix. Figures 1 to 3 The present invention will be described in detail with reference to the embodiments.

[0026] Overall, this utility model relates to a magnetic separation column discharge and slag removal device, including a stabilizing chamber 1, a feed pipe 2 connected to the stabilizing chamber 1, a slag removal trough 4 inclined and fixedly installed on the upper part of the side wall of the stabilizing chamber 1, and a slag-separating screen 8 fixedly installed at the top opening of the slag removal trough 4. The end of the slag removal trough 4 away from the stabilizing chamber 1 is inclined downward, and the material enters the slag removal trough 4 from the stabilizing chamber 1 and flows along its inclination. A connecting pipe 5 is connected to the bottom of the slag removal trough 4, and one end of the connecting pipe 5 is connected to the connecting groove 7.

[0027] In this embodiment, the slag-blocking mesh 8 at the top opening effectively intercepts non-magnetic impurities such as rubber, fiber, and large pieces of waste rock, preventing them from entering the subsequent sorting process and reducing the risk of magnetic column blockage. The flow stabilizing chamber 1 balances the fluctuation of the feed pressure, ensuring that the material flows evenly into the slag-cleaning tank 4 and preventing the slag-blocking mesh 8 from being overloaded or damaged due to sudden changes in flow rate.

[0028] In detail, large particulate impurities are removed in advance through physical interception, which avoids wear on the magnetic separation column sorting medium and extends the equipment life.

[0029] It should be noted that the slag removal tank 4 is fixed at an inclined angle, and the impurities are driven by gravity to slide down naturally to the bottom connecting pipe 5, which does not require additional power equipment and reduces energy consumption.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the slag cleaning tank 4 is preferably fixed at an inclination angle of 8.1°.

[0031] In practice, the slurry discharged from the magnetic separation column enters the stabilizing chamber 1 through the feed pipe 2. When the slurry flows through the top slag screen 8, non-magnetic impurities (such as rubber and wood chips) are trapped on the screen surface, forming a filter cake layer; magnetic particles and fine gangue particles pass through the mesh and enter the downstream of the slag cleaning tank 4. The filtered slurry flows from the end of the slag cleaning tank 4 into the connecting pipe 5, and finally enters the connecting tank 7 to await further processing.

[0032] Preferably, the filter screen 8 can be driven by a vibrating motor, which vibrates periodically to cause the filter cake layer to fall off and be collected, preventing the mesh from clogging.

[0033] Among them, such as Figure 3 As shown, the slag screen 8 includes vertical rods 801 and horizontal rods 802. Multiple vertical rods 801 are spaced apart, and their two ends are fixedly connected to the two side walls of the slag cleaning tank 4. Multiple horizontal rods 802 are fixedly spaced apart on the bottom surface of each vertical rod 801.

[0034] In this embodiment, the cross reinforcement design of the vertical bar 801 and the horizontal bar 802 increases the ability of the slag screen 8 to withstand the impact of slurry, thus avoiding deformation and breakage.

[0035] Based on the above configuration, the spacing between each vertical rod 801 is preferably 3mm. This spacing can further increase the interception rate of the filter screen 8. In addition, the intercepted impurities form a "bridging" filter cake layer between the vertical rods 801, further filtering finer particulate impurities and achieving gradual purification.

[0036] It should be noted that the top of the feed pipe 2 is equipped with an inverted conical feed hopper 201 that is wider at the top and narrower at the bottom. This configuration transforms intermittent feeding into a continuous and uniform flow, reducing the impact load of the material on the slag screen 8.

[0037] It should be further explained that the feed pipe 2 is connected and installed on the lower side wall of the stabilizing bin 1. This configuration can reduce the height difference between the inlet and outlet, avoid the feed material directly impacting the bottom sediment layer of the stabilizing bin 1, and at the same time use the kinetic energy of the feed to drive the material at the bottom of the bin to flow slowly, preventing the ore sand from caking.

[0038] As a preferred structure in this embodiment, such as Figure 2 As shown, a drain outlet 3 is provided on the lower side wall of the stabilizing chamber 1 to facilitate the discharge of slurry from the stabilizing chamber 1 during maintenance. In practice, a valve is provided at the drain outlet 3.

[0039] In addition, in order to facilitate the collection of impurities filtered by the slag screen 8, a slag discharge trough 6 is fixedly provided on the end of the slag cleaning trough 4 away from the flow stabilizing chamber 1.

[0040] In practice, after the impurities are intercepted by the slag screen 8, they slide along the bottom plate of the slag cleaning tank 4 to the slag discharge tank 6 under the action of slurry flow and gravity, so as to avoid the impurities from settling in the slag cleaning tank 4 or flowing back with the slurry.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
