[0029] Coal is a solid combustible mineral formed gradually from ancient plants buried underground and undergoing complex biochemical and physicochemical changes.
[0030] Iron filings are often present in coal samples during preparation, affecting their testing data. Currently, permanent magnets are commonly used to directly remove iron impurities from coal. However, this method suffers from drawbacks such as difficulty in collecting iron filings, easy scattering of the coal sample during adsorption, significant variations in human error, and low iron removal efficiency. Therefore, a coal sample iron removal device is urgently needed to address these technical problems.
[0031] like Figure 1As shown, this embodiment provides a coal sample iron removal device, which includes an iron removal box 1, a sample tray 2, an iron removal mechanism 3, and a collection tray 4. The iron removal box 1 has a receiving cavity 11 inside, and the sample tray 2 is movably installed in the receiving cavity 11 and configured to support the coal sample. The iron removal mechanism 3 includes an electromagnetic tube 31, which is disposed in the receiving cavity 11. When the electromagnetic tube 31 is energized, it can adsorb iron filings in the coal sample on the sample tray 2. The collection tray 4 is movably installed in the receiving cavity 11. When the electromagnetic tube 31 is de-energized, the iron filings adsorbed on the electromagnetic tube 31 fall into the collection tray 4 under its own weight.
[0032] In this embodiment, the iron removal box 1 has a receiving cavity 11 inside, and the sample tray 2 is movably installed in the receiving cavity 11 and configured to support the coal sample. This allows the sample tray 2 to easily enter and exit the iron removal box 1, facilitating the placement and removal of the coal sample and improving operational convenience. Moreover, the iron removal process of the coal sample is completed entirely within the receiving cavity 11, preventing the coal sample from scattering. The iron removal mechanism 3 includes an electromagnetic tube 31, which is disposed in the receiving cavity 11. When the electromagnetic tube 31 is energized, it can adsorb iron filings from the coal sample on the sample tray 2. Compared with traditional permanent magnets, the electromagnetic tube 31 has stronger adsorption force and more flexible control, making operation more convenient and faster for operators and avoiding significant differences in human operation. The collection tray 4 is movably installed in the receiving cavity 11. When the electromagnetic tube 31 is de-energized, the iron filings adsorbed on the electromagnetic tube 31 fall into the collection tray 4 under its own weight, thereby improving the convenience of iron filings collection. With the above settings, the coal sample iron removal device of this embodiment can more conveniently and quickly collect iron filings, and the coal sample is less likely to scatter.
[0033] The specific structure of the iron removal device for coal samples is described below:
[0034] Specifically, such as Figure 1 As shown, the sample tray 2 is slidably connected to the iron removal box 1 in the horizontal direction, so that the sample tray 2 can enter and exit the iron removal box 1 smoothly and steadily, reducing the risk of coal samples scattering during the movement.
[0035] More specifically, in this embodiment, the iron removal box 1 is provided with a slide rail, and the sample tray 2 is provided with a slider that is slidably connected to the slide rail, thereby realizing the stable directional sliding of the sample tray 2 relative to the iron removal box 1.
[0036] Specifically, the coal sample iron removal device also includes a sliding drive 5, the output end of which is connected to the sample disk 2 and can drive the sample disk 2 to slide, thereby realizing the automated movement of the sample disk 2 and improving the automation and efficiency of the iron removal process.
[0037] More specifically, in this embodiment, the sliding actuator 5 includes a motor and a lead screw. The rotational output end of the motor is connected to the lead screw, and the slider is threadedly connected to the lead screw and slides in cooperation with the slide rail. The motor drives the lead screw to rotate, which in turn drives the slider to slide along the extension direction of the slide rail, thereby causing the sample tray 2 to slide stably relative to the iron removal box 1. In other embodiments, the sliding actuator 5 includes a cylinder. The extension output end of the cylinder is connected to the slider, which then drives the slider to slide along the extension direction of the slide rail. The specific structure of the sliding actuator 5 is not limited here, as long as it can achieve the above-mentioned functions.
[0038] Specifically, the sample tray 2 is provided with a limiting plate 21. When the sample tray 2 slides relative to the iron removal box 1, the limiting plate 21 can abut against the iron removal box 1, thereby limiting the stroke of the sample tray 2, preventing the sample tray 2 from moving excessively during the sliding process, and ensuring the stability and safety of the iron removal process.
[0039] Specifically, the sample tray 2 is provided with a baffle 22, which forms a storage tank 221 for holding the coal sample. This prevents the coal sample from scattering during the iron removal process and ensures the integrity and accuracy of the coal sample.
[0040] Specifically, the iron removal mechanism 3 also includes an iron removal controller 32. The output end of the iron removal controller 32 is connected to the solenoid tube 31, which can control the magnetic strength of the solenoid tube 31, thereby achieving flexible adjustment of the adsorption force of iron filings and improving the accuracy and controllability of the iron removal process. The iron removal controller 32 can be a current controller or a current regulator. By adjusting the intensity of the output current, the magnetic strength of the solenoid tube 31 can be adjusted, thereby achieving adjustment of different adsorption forces on iron filings to meet the needs of specific working conditions.
[0041] More specifically, in this embodiment, the solenoid 31 includes an electromagnetic coil and a magnetic core. The electromagnetic coil is helical and wound around the magnetic core. When energized, the electromagnetic coil generates a magnetic field around itself. The direction of this magnetic field is determined by the direction of the current and the shape of the electromagnetic coil, and the strength of the magnetic field is proportional to the current intensity. The magnetic field is further enhanced by the magnetic core, enabling the solenoid 31 to generate stronger magnetism when energized, thereby attracting impurities such as iron filings.
[0042] Specifically, multiple electromagnetic tubes 31 are provided, and the multiple electromagnetic tubes 31 are arranged at intervals in the horizontal direction, which can expand the adsorption area of iron filings and improve the adsorption efficiency of iron filings.
[0043] Specifically, the solenoid tube 31 is rotatably connected to the iron removal box 1 around its own axis, which makes the iron filings more evenly distributed during the adsorption process, avoiding the problem of iron filings accumulating on the solenoid tube 31 and improving the adsorption efficiency and lifespan of the solenoid tube 31. The rotation of the solenoid tube 31 can be achieved by driving a stepper motor or a servo motor, which will not be elaborated further here.
[0044] Specifically, the collection tray 4 is slidably connected to the iron removal box 1 in the horizontal direction, which makes the collection tray 4 easy to move and remove, improving the convenience of operation.
[0045] More specifically, the collection tray 4 is equipped with a handle 41, which allows the operator to pull and retract the collection tray 4 by holding the handle 41, thereby improving the convenience of collecting and handling iron filings.
[0046] It should be noted that in this embodiment, the sample tray 2 and the collection tray 4 are slidably connected to the iron removal box 1, thereby improving the pulling and retraction of the sample tray 2 and the collection tray 4. In other embodiments, the sample tray 2 and the collection tray 4 can also be installed by means of plugging or snapping, which will not be described in detail here.
[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
