Description

Technical Field

[0001] The utility model relates to the technical field of material separation, in particular to an iron removal device suitable for a belt conveyor. Background Art

[0002] Belt conveyors are widely used in mining, metallurgy, building materials, food and other industries. They are energy-saving, efficient, highly automated and highly adaptable, and can greatly reduce manual labor. For steel companies, when using belt conveyors to transport materials, iron debris is often mixed in the materials. These iron debris enter the subsequent crusher or roller mill with the materials, which can easily get stuck, damage the equipment, and even cause the entire production line to be paralyzed. Therefore, iron removers are used to separate the iron debris. The existing iron removers have the following problems in the process of removing iron debris: First, the height of the iron remover is fixed. If the iron remover is set too low, it will affect material transportation, and if it is set too high, it will affect the adsorption of iron debris; second, the amount of iron debris adsorbed by the iron remover is random. If too much iron debris is adsorbed and not cleaned up in time, it will affect the subsequent removal of iron debris.

[0003] The application number is CN201921959464.X and the name is "A new type of mining electromagnetic iron remover with automatic unloading". By adding telescopic and sliding devices, the electromagnetic iron remover can be moved, and an electromagnetic control device is added; the one-button operation of the electromagnetic iron remover is realized, and the iron can be unloaded during the operation of the belt, reducing the time of stopping the belt conveyor when the iron remover unloads the iron, but it does not completely solve the above problems.

The CPU can use the C8051F340 series chip, and the SILICONLABS and 8051F340-GQR models can be selected.

[0021] The direction indicated by the arrow in the figure is the running direction of the belt. The distance measuring part and the iron removal part 3 are arranged below the bracket 1. The distance measuring part is arranged at the upstream position of the iron removal part 3. When the material on the belt 4 passes under the distance measuring part, the distance measuring part detects the height of the material, so that the lifting component 3-1 can adjust the magnet 3-2 to an appropriate height to avoid the magnet 3-2 being set too high, which is not conducive to completely removing the iron debris in the material, and setting it too low may block the passage of the material.

[0022] The distance measuring part is composed of laser distance measuring sensors 2, the number of which is 3-5, which are arranged on the bracket 1 in a direction perpendicular to the running of the belt. The signal output of the laser distance measuring sensor 2 is connected to the input end of the CPU. The laser distance measuring sensor 2 can be MyAntennaL1-40 or other general models; the distance measuring part can also use ultrasonic distance measuring sensors. 3-5 laser distance measuring sensors 2 are arranged in a direction perpendicular to the running of the belt. If the number is 3, one can illuminate the middle position of the belt, and the other two can illuminate the positions on both sides of the belt respectively. It can not only measure the material height in the middle part of the belt, but also measure the material height on both sides of the belt that deviate from the middle, and the height data is more accurate.

The electric cylinder 3-1-4 can be selected from the BDL-52X series of Dingshen Technology or the strong electric cylinder. The electric cylinder 3-1-4 can be replaced by a hydraulic cylinder or a pneumatic cylinder.

[0024] In actual production, it often happens that too much iron impurities are adsorbed on the magnet 2 and not cleaned in time, thus affecting the removal of iron impurities in the subsequent materials. The following scheme can be used to remind when the amount of iron impurities adsorbed on the magnet 2 is too much. A tension sensor 6 is arranged between the base 3-1-1 and the bracket 1. The number of the tension sensors 6 is 4; the signal output of the tension sensor 6 is connected to the input end of the CPU, and one output end of the CPU is connected to the relay, the sound chip IC, and the speaker SP in sequence through the transistor amplifier circuit. The connection method is similar to the connection control electric cylinder 3-1-4. . The tension sensor 6 can use the Jinnuo S-type tension sensor. According to the weight of the lifting component and the required weight of the adsorbed iron impurities, the range of 0-200Kg or 0-500Kg can be selected; the number of tension sensors 6 can be set to 4.

[0025] After the magnet absorbs the iron impurities to the upper limit, the iron removal part 3 can be automatically moved out to facilitate the cleaning of the iron impurities. The following scheme is adopted: a translation assembly 5 is arranged between the base 3-1-1 and the bracket 1, and the translation assembly 5 is composed of a translation slide 5-1 and a second guide rail 5-2; the second guide rail 5-2 is connected to the bracket 1; a slider matching the second guide rail 5-2 is arranged on the translation slide 5-1; a rack 5-3 is arranged on the translation slide 5-1, and the rack 5-3 is meshed with a gear 5-4 arranged on the bracket 1, and the gear 5-4 is driven by a drive motor 5-5; a tension sensor 6 is arranged between the base 3-1-1 and the translation slide 5-1, and the signal output of the tension sensor 6 is connected to the input end of the CPU, and one output end of the CPU is connected to the transistor amplifier circuit, the relay and the drive motor 5-5 in sequence, and the connection method is similar to the connection control electric cylinder 3-1-4.

[0026] In order to realize the automatic release of iron impurities, the following scheme is adopted: the magnet 3-2 is an electromagnet, and one output end of the CPU is connected to the transistor amplifier circuit, the relay and the electromagnet in sequence. Figure 3 The connection method of the second guide rail 5-2 is omitted, and is similar to that of the control electric cylinder 3-1-4. There are two second guide rails 5-2, which are arranged in parallel. When too much iron impurities are adsorbed on the magnet, the CPU controls the translation component to move the iron removal part out of the belt, and then cleans the iron impurities or controls the electromagnet to release the iron impurities.
