Description

Technical Field

[0001] This invention patent relates to the field of metallurgical material equipment impurity removal technology, and is particularly applicable to adjustable self-cleaning temperature-controlled iron removal devices for removing ferromagnetic impurities from bulk materials in industries such as mining and metallurgy. Background Technology

[0002] The following defects are commonly found in iron separators used in actual production, affecting their efficiency and service life.

[0003] 1. Limited performance of magnetic materials and poor environmental adaptability. Permanent magnets (such as neodymium iron boron) are prone to demagnetization after long-term use in continuous production, especially in high-temperature environments, where this degradation is significant (potentially decreasing by 1% to 3% per year). When the temperature exceeds 80°C, the performance of permanent magnets drops sharply, and the insulation layer of the electromagnetic coil is prone to aging. At the same time, traditional electromagnetic separators require continuous power supply during operation, resulting in high energy consumption, and the coil is prone to failure when overheated.

[0004] 2. Mechanical structure and maintenance issues. Self-unloading magnetic separators are prone to blockage due to material adhesion (especially in supermarket environments), which can lead to malfunctions such as scraper conveyor jamming and transmission mechanism failure. Traditional permanent magnet magnetic separators require manual operation and regular cleaning during shutdown, affecting continuous production. Summary of the Invention

[0005] To address the aforementioned shortcomings, the present invention aims to provide an adjustable self-cleaning temperature-controlled iron removal device.

[0006] To achieve the above objectives, the adjustable self-cleaning temperature-controlled iron removal device of the present invention includes: a first support frame, which is mounted across a conveyor belt; and an electromagnetic iron remover is mounted on the first support frame. A scraper is provided on the first bracket corresponding to the iron remover for scraping off iron filings on the iron remover; A discharge chute is provided on the first support corresponding to the scraper; A second support is disposed upstream of the first support, and the second support spans across the conveyor belt; a metal detection device is disposed on the second support corresponding to the conveyor belt.

[0007] Furthermore, a Hall sensor is installed on the support corresponding to the electromagnetic separator to sense the real-time magnetic field strength of the electromagnetic separator; the signal output terminal of the Hall sensor is connected to the signal input terminal of the control device.

[0008] Furthermore, a camera device is installed on the second support to capture images of the amount of iron impurities adsorbed onto the surface of the iron remover and output the images to the machine vision monitoring system. The machine vision monitoring system outputs control signals to adjust the magnetic field strength based on the captured images.

[0009] Furthermore, a vibrator is provided on the support near the scraper and / or the discharge chute.

[0010] Furthermore, the electromagnetic separator is provided with an air-cooling channel, and a temperature-controlled fan is installed inside the air-cooling channel.

[0011] Furthermore, a spare electromagnetic separator is also arranged side by side on the first support, and the control device controls the two electromagnetic separators to work alternately according to a predetermined degree.

[0012] The present invention has the following advantages: 1. Use a metal detection device to control the working status of the electromagnetic separator to prevent damage caused by overheating.

[0013] 1. For the first time, vibration cleaning and mechanical scraping are combined, increasing cleaning efficiency to 99.7%.

[0014] 2. Two sets of electromagnetic separators are used to work alternately, and the heat dissipation structure is optimized, which reduces the equipment failure rate.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example 1 like Figure 1 and Figure 2 As shown, the adjustable self-cleaning temperature-controlled iron removal device of this embodiment includes: Drawing number explanation: 1. Air-cooled duct 2. Electromagnetic separator 3. Scraper assembly 4. Unloading chute 5. Vibration device 6. Infrared sensor camera 7. Metal detector 8. Protective bracket 9. Conveyor belt conveyor Includes: a first support 11, which spans across the conveyor belt 9; an electromagnetic separator 2 is installed on the first support; the electromagnetic separator generally consists of multiple sets of electromagnets and an electric conveyor belt arranged around the electromagnets, the electromagnets are used to adsorb iron filings from the material on the conveyor belt below; the rotation of the electric conveyor belt is used to transport iron-containing impurities to one side under the action of the magnetic field. A scraper 3 is provided on the first support corresponding to the belt surface of the electric conveyor belt of the iron remover, for scraping off iron filings from the belt surface of the iron remover. A discharge chute 4 is provided on the first support corresponding to the scraper; the iron filings scraped off by the scraper slide down the discharge chute for easy collection; A second support 12 is provided upstream of the first support, and the second support spans across the conveyor belt; a metal detection device 7 is provided on the second support corresponding to the conveyor belt. It also includes a control device for receiving signals from the metal detection device to drive the magnetic separator to open and close according to a predetermined program. The predetermined program refers to calculating the arrival time at the magnetic separator based on the distance between the second support and the first support, and the operating speed of the conveyor belt 9, after receiving the signal from the metal detection device. The magnetic separator is then put into magnetic separation mode before this arrival time, for example, for 5-50 seconds; and shut down the magnetic separator after a certain period following the receipt of the metal detection device signal, thus maximizing control over the working time of the magnetic separator.

[0024] Example 2 Based on the above embodiment, a Hall sensor is installed on the support corresponding to the electromagnetic separator to sense the real-time magnetic field strength of the electromagnetic separator; the signal output terminal of the Hall sensor is connected to the signal input terminal of the control device; this is to prevent the magnetic field strength from changing due to problems such as heating of the electromagnetic separator as the working time increases, thereby affecting the magnetic separation effect.

[0025] A camera device is installed on the second support to capture images of the amount (thickness) of iron impurities adsorbed onto the belt surface of the iron separator. The image data is then output to a machine vision monitoring system. Based on the captured images, the machine vision monitoring system outputs control signals to drive the electric conveyor belt of the iron separator to rotate and adjust the magnetic field strength. For example, when the iron filings are 5 mm thick, the magnetic field strength is 0.5 T; when the iron filings are thicker than 5 mm but less than 10 mm, the magnetic field strength is 0.7 T. When the thickness exceeds 10 mm, the electric conveyor belt is driven to rotate towards the scraper to scrape off the iron filings from the belt surface.

[0026] Example 3 Based on the above embodiments, a vibrator is installed on the support near the scraper and / or the unloading chute to prevent some iron filings from accumulating for a long time.

[0027] Example 4 Based on the above embodiment, a cooling channel is provided between two adjacent electromagnets in the electromagnetic separator, and a temperature-controlled fan is installed in the cooling channel to prevent the electromagnets from being damaged due to prolonged high temperatures.

[0028] Example 5 Based on the above embodiment, a spare electromagnetic separator is also arranged side by side on the first support. The control device controls the two electromagnetic separators to work alternately according to a predetermined degree, so as to reduce the equipment failure rate. For example, the switching can be performed according to the working time, such as switching each electromagnetic separator once every 4 hours of operation.

[0029] Example 6 Based on the above embodiment, a protective support 8 is also provided upstream of the second support to prevent excessively high material surfaces from impacting the equipment on the second support.

[0030] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
