Description

Technical Field

[0001] The utility model relates to the technical field of iron concentrate screening, and specifically relates to an extraction device for iron concentrate. Background Art

[0002] As the main raw material for pellets, iron concentrate is obtained from iron ore through a series of processing procedures such as crushing, grinding, and beneficiation. The fluctuation of its iron content is directly related to the quality of the finished pellet ore. In the production process, the use of extraction equipment is crucial for obtaining iron concentrate.

[0003] However, in the prior art, after iron ore is ground, iron concentrate needs to be extracted for further processing. However, in actual use, when iron concentrate (usually together with water and iron ore powder) enters the extraction equipment, the mixture is prone to splashing when colliding with other objects. This not only causes waste of some powder, but also if the mixture is dry, the powder will disperse in the air and is extremely easy to be inhaled by workers, causing serious harm to the human body and bringing great trouble. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

[0007] It should be noted that in the above, by pouring the raw materials into the inside of the crushing box, the ore is crushed and ground by the crusher inside the crushing box. The crushed parts are unidirectionally drained through the horn-shaped drainage block. At the same time, the crushed ore is drained through the one-way drainage valve. At the same time, the crushed ore is drained into the inside of the collecting shaft tube through the one-way drainage valve. At the same time, through the cooperation of the spider-web metal bracket and a number of screening metal rods, the ore is electrically screened and drained.

[0008] Preferably, the magnetic drainage assembly includes: a sidewall arc-shaped metal plate, a number of conductive metal balls and an adsorption electromagnet;

[0009] The sidewall arc-shaped metal plate is inserted on the sidewall of the cylindrical screening box. The adsorption electromagnet is installed on the sidewall arc-shaped metal plate. A number of conductive metal balls are respectively movably inserted on the sidewall arc-shaped metal plate;

[0015] Beneficial effects

[0016] The utility model provides an extraction device for iron concentrate powder, which has the following beneficial effects: for the extraction device of iron concentrate powder, through a specially designed crushing box and an internal crusher, the ore can be efficiently crushed and ground into powder with the required particle size. Compared with traditional methods, this mechanized crushing method greatly improves the processing efficiency and output; by using the design of a horn-shaped drainage block, it effectively guides the crushed ore powder to flow unidirectionally, avoiding blockage and backflow. The unidirectional drainage valve further ensures that the ore powder can smoothly enter the collecting shaft tube, preparing for subsequent processing; through the precise cooperation of a cobweb metal bracket and multiple screening metal rods, the ore powder is accurately screened to achieve the separation of different particle sizes. This screening method not only has high efficiency but also high screening accuracy, which helps to improve the quality of subsequent processing; by using a magnetic drainage component to transfer magnetism to the arc-shaped metal block, and then through the arc-shaped metal block to transfer magnetism to the cobweb metal bracket and screening metal rods, magnetic adsorption of metal impurities in the ore powder is achieved; this method can efficiently separate the metal components in the ore and improve the purity of the ore; through the rotational movement of the rotating disk, the collecting shaft tube is rotated one by one to the shunt transporter on the concave transporter, realizing the shunt drainage of metal powder and ore powder. This design makes the whole screening and separation process more automated and efficient; by controlling the on-off of the adsorption electromagnet, the magnetic state of the sidewall arc-shaped metal plate can be flexibly adjusted, thereby controlling the magnetic adsorption and discharging of the ore powder. This intelligent control method makes the operation more simple and fast, and also improves the flexibility and adaptability of the device; when discharging is required, only by cutting off the power supply of the adsorption electromagnet, the sidewall arc-shaped metal plate can lose magnetism, thus realizing the automatic discharging of the ore powder. This method not only improves the discharging efficiency but also reduces the need for manual intervention; the whole system has a compact and reasonable structure, and the cooperation between components is tight and orderly, which not only improves the space utilization rate but also is convenient for daily maintenance and repair; for the design of vulnerable parts such as screening metal rods and arc-shaped metal blocks, the convenience of replacement is considered, which is convenient for timely replacement after wear to ensure the normal operation of the device.
