Description

Technical Field

[0001] The utility model relates to the technical field of magnetic mineral screening, and particularly relates to a discharging device for a wet magnetic separator. Background Art

[0002] A wet magnetic separator, also known as a water-washed magnetic separator, is a mainstream strong magnetic separator beneficiation equipment, which is widely used in the separation of ores such as iron ore and manganese ore. It adopts a wet operation mode and is suitable for the wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with a particle size of less than 3 mm, and is also used for the iron removal operation of materials such as coal, non-metallic minerals and building materials.

[0003] The magnetic separator mainly consists of components such as a tank body, a magnetic system, a transmission part, magnetic blocks, and a roller. The tank body is composed of a feed tank, a feeding area and a return material area. The magnetic system is responsible for generating a strong magnetic field to attract and separate magnetic substances. The transmission part includes a motor, a reducer, a pulley, a belt, etc., and is used to drive the rotation of the roller of the magnetic separator. The magnetic block is a key component for generating a magnetic field. The roller is a component in the magnetic separator for carrying the magnetic system.

[0004] The working principle of the wet magnetic separator is mainly based on the different behaviors of magnetic and non-magnetic materials in a magnetic field. When the pulp flows through the magnetic field area of the magnetic separator, the magnetic minerals will be adsorbed on the roller of the magnetic separator, and with the rotation of the roller, they will be brought to an area with a weaker magnetic field, and then the magnetic minerals will be unloaded through flushing water or other means, so as to realize the separation of magnetic minerals and non-magnetic minerals.

[0005] Under the existing technology, the way to unload the magnetic minerals on the roller of the wet magnetic separator is to set a water pipe. The water pipe is located on one side of the roller of the wet magnetic separator and is as long as the roller. Sprayers are installed at certain intervals on the upper part of the water pipe. The purified water for unloading ore is sprayed out from each sprayer and sprayed onto the rotating roller, and finally the magnetic minerals are unloaded from the surface of the roller. However, since the thickener for manufacturing the purified water is usually set outdoors and is in the open air, impurities such as branches, weeds, plastics and wood chips will be mixed into the purified water. If the purified water with impurities enters the water pipe, it will cause the sprayers to be blocked, resulting in the inability to completely unload the magnetic minerals selected by the magnetic separator, thus affecting the tailings index. At the same time, the water pressure at the water outlet of the sprayer is too high, and the water splashes, resulting in poor on-site environmental hygiene. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a discharging device for a wet magnetic separator to solve the problem that the magnetic minerals cannot be completely unloaded if the sprayer at the existing discharging device is blocked.

[0007] To achieve the above object, the basic solution provided by the present utility model is as follows: A discharging device for a wet magnetic separator includes a water tank, the water tank is fixedly connected to the housing of the magnetic separator, the water tank is located on one side of the roller of the magnetic separator, a deflector is fixedly connected to the water tank, the other end of the deflector is adjacent to the roller of the magnetic separator, and a water supply assembly for injecting water into the water tank is provided on the water tank.

[0008] The principle and beneficial effects of the present utility model are as follows: By changing the original discharging device that uses a spray head to spray water for discharging ore to a water tank with a deflector, filling the water tank with water and continuously injecting water, the overflowing water flushes the surface of the roller of the magnetic separator through the deflector, and the magnetic minerals on the surface of the roller are removed. Utilizing the overflow of water in the water tank facilitates completely removing the magnetic minerals on the surface of the roller of the magnetic separator without being troubled by blockage.

[0009] Solution two, which is the preference of the basic solution. The water supply assembly includes a steel pipe, the steel pipe is placed on the water tank, a hose is sleeved at one end of the steel pipe outside the water tank, the other end of the hose is connected to a water pump, a pipe is connected to the water pump, and the other end of the pipe is connected to a water tank. Through the setting of the water supply assembly, it is convenient to continuously supply water to the water tank.

[0010] Solution three, which is the preference of the basic solution. Two baffles are fixedly connected to the outer walls on opposite sides of the water tank, the two baffles are respectively located on both sides of the deflector, and the other ends of the two baffles are both adjacent to the roller of the magnetic separator. Through the setting of the baffles, it is convenient to prevent the water on the deflector from overflowing from both sides of the deflector.

[0011] Solution four, which is the preference of the basic solution. A semi-circular groove is provided on the water tank. Through the setting of the semi-circular groove, it is convenient to place the steel pipe in the semi-circular groove to prevent the position of the steel pipe from shifting.

[0012] Solution five, which is the preference of the basic solution. A zinc layer is provided on the outer wall of the deflector. Since the deflector is made of steel material, the steel material is prone to rust when in contact with water and oxygen for a long time. Through the setting of the zinc layer, it is convenient to prevent the deflector from rusting, so as to reduce the replacement frequency of the deflector. Description of the Drawings
