Description

Technical Field

[0001] This utility model relates to the field of iron removal technology, specifically a self-unloading iron removal device. Background Technology

[0002] Iron separators are mechanical devices that separate iron and magnetic substances from materials using magnetic fields. They are mainly used in ceramics, mining, chemical, food processing, and new energy materials industries.

[0003] The core working principle of a magnetic separator is to use the magnetic attraction of a magnetic field to separate iron and magnetic substances mixed in with the material. In the operation process of a traditional magnetic separator, iron impurities are attracted to the surface of the belt under the action of the magnetic field inside the equipment. When the belt carries the iron impurities to the unloading area, the magnetic field disappears in that area, and the iron impurities fall off the belt surface under the combined action of their own gravity and the centrifugal force generated by the belt rotation, completing one iron removal cycle, thereby achieving continuous and automatic removal of iron impurities from the material.

[0004] However, traditional iron separators generally adopt a "continuous operation" mode, meaning the equipment remains running regardless of whether the amount of iron impurities adsorbed on the belt surface has reached the threshold requiring cleaning. This operating mode has significant drawbacks: on the one hand, when the amount of iron impurities adsorbed is small, the continuous operation of the equipment will result in a large waste of electrical energy, which is inconsistent with the current development trend of energy conservation and emission reduction in the industrial field; on the other hand, long-term idling or low-load operation will accelerate the wear of core components such as belts, rollers, and motors, shorten the service life of the equipment, and increase the equipment maintenance and replacement costs for enterprises. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model proposes a self-unloading iron remover that can accurately detect the amount of iron impurities adsorbed and activate the iron unloading function as needed.

[0006] To solve the above-mentioned technical problems, this utility model provides a self-unloading iron remover, including a frame and an iron unloading belt. Two sets of spaced upper roller assemblies are installed on the top of the frame. A redirecting roller assembly and a transmission roller assembly are respectively installed at both ends of the bottom of the frame. A drive motor is fixed at one end of the frame. The drive motor is connected to the transmission roller assembly through a transmission box. The iron unloading belt is wound around the redirecting roller assembly, the transmission roller assembly, and the two sets of upper roller assemblies. A mounting frame is provided in the middle of the frame. A second magnetic system is fixed at the bottom of the mounting frame. Iron detection components are symmetrically arranged on both sides of the second magnetic system. The contact end of the iron detection component faces the second magnetic system and abuts against the inner end face of the iron unloading belt.

[0007] Preferably, the iron detection assembly includes a nylon rod and a detection probe. The nylon rod is mounted on one side of the second magnetic system via a support frame. The nylon rod is slidably connected to the support frame. A detection bolt is provided at the top of the nylon rod. The detection probe is mounted on the top of the support frame and faces the detection bolt.

[0008] Preferably, the mounting frame is provided with a support plate, the support frame includes a lower support plate, and support rods passing through the support plate are fixed at the four corners of the top of the lower support plate. An upper support plate is installed between the four sets of support rods. The upper support plate and the lower support plate are respectively located on the upper and lower sides of the support plate. The support rods are provided with two sets of axially distributed first adjusting nuts. The two sets of first adjusting nuts abut against the upper and lower sides of the support plate respectively. The nylon rod is slidably engaged with the lower support plate, and the detection probe is installed at the bottom of the upper support plate.

[0009] Preferably, the contact end of the nylon rod passes through the support plate and the lower support plate and abuts against the inner end face of the unloading belt. The nylon rod has a frustum in the middle, which abuts against the upper end face of the lower support plate. A spring is sleeved on the outer periphery of the nylon rod, and the spring abuts between the support plate and the frustum.

[0010] Preferably, the top end of the support rod passes through the upper support plate, and the support rod body is provided with two sets of axially distributed second adjusting nuts, the two sets of second adjusting nuts respectively abutting against the upper and lower sides of the upper support plate.

[0011] Preferably, the redirecting roller assembly has a first magnetic system inside, which is a semi-cylindrical structure and is arranged coaxially with the redirecting roller assembly.

[0012] Preferably, a protective cover is installed on the support plate, and the protective cover covers the outside of the iron detection assembly to form a protective space.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: When sufficient iron impurities are adsorbed onto the surface of the unloading conveyor belt, it is pushed upwards. Simultaneously, the belt compresses the nylon rod, causing it to move upwards. As the detection bolt above the nylon rod approaches the detection probe, the probe sends a signal indicating it is in position, energizing the drive motor and starting the unloading conveyor belt to eject the iron impurities, completing the operation. This iron impurity detection component enables precise detection, activating the unloading conveyor belt only when iron impurities reach a set threshold. This significantly reduces equipment idle time and lowers energy consumption. Furthermore, the reduced operating time decreases wear on the unloading conveyor belt, rollers, and other components, extending their replacement cycle. Attached Figure Description

It should be understood that the specific embodiments described herein are only configured to explain the present utility model and are not configured to limit the present utility model. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present utility model by illustrating examples of it.

[0018] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this utility model. It should also be noted in the description of this utility model that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figure 1As shown, the self-unloading iron remover includes a frame 1 and an iron removal belt 5. Two sets of spaced-apart upper idler roller assemblies 6 are mounted on the top of the frame 1, and a redirecting roller assembly 7 and a drive roller assembly 11 are respectively mounted at both ends of the bottom of the frame 1. The iron removal belt 5, serving as the adsorption and conveying carrier for iron impurities, winds around the outer periphery of the redirecting roller assembly 7, the drive roller assembly 11, and the two sets of upper idler roller assemblies 6, forming a closed belt running path.

[0020] A drive motor 2 is fixed at one end of the frame 1. The drive motor 2 is connected to the transmission roller assembly 11 via a transmission box 3. The transmission box 3 is equipped with a reduction and power distribution mechanism, which can convert the high-speed rotational power output by the drive motor 2 into a speed and torque suitable for the transmission roller assembly 11, ensuring that the unloading belt 5 operates at a stable and uniform speed, and avoiding the impact of speed fluctuations on the unloading effect.

[0021] A mounting frame 4 is provided in the middle of the frame 1, and a second magnetic system 10 is fixed at the bottom of the mounting frame 4. The second magnetic system 10 can form a stable and strong magnetic field area. When the material passes through this magnetic field area, the iron impurities in it will be firmly adsorbed on the outer surface of the unloading belt 5 under the influence of the magnetic field, laying the foundation for subsequent separation and unloading.

[0022] The reversing roller assembly 7 has a first magnetic system 8 inside, which is a semi-cylindrical structure and is arranged coaxially with the reversing roller assembly 7. The core function of this structural design is that it can provide a stable magnetic field to adsorb iron impurities during the critical stage of the operation of the unloading belt 5, and can also precisely cut off the magnetic field at a specific position to achieve iron unloading.

[0023] When the unloading belt 5 carries iron impurities around the redirecting roller assembly 7, the iron impurities will always be within the magnetic field adsorption range in the half-cylinder area covered by the first magnetic system 8, ensuring that they move stably with the unloading belt 5 and preventing them from falling off prematurely due to the centrifugal force generated by the rotation of the unloading belt 5. When the unloading belt 5 carries the iron impurities to an area not covered by the first magnetic system 8, the iron impurities will instantly lose the magnetic field adsorption force and fall off the surface of the unloading belt 5 under the combined action of their own gravity and the centrifugal force generated by the operation of the unloading belt 5, thus completing the unloading work.

[0024] like Figure 2 and Figure 3As shown, the mounting frame 4 is equipped with a support plate 21, which is located above the second magnetic system 10, providing a stable mounting reference for the subsequent iron detection assembly 9. The iron detection assemblies 9 are symmetrically arranged on both sides of the support plate 21. The contact end of the iron detection assembly 9 faces the second magnetic system 10 and abuts against the inner end face of the unloading belt 5, so as to be able to sense the amount of iron impurities adsorbed on the surface of the unloading belt 5 in real time. A protective cover 15 is fixedly installed on the support plate 21, which covers the outside of the iron detection assembly 9 to form a protective space, preventing dust, material particles and other impurities generated during the production process from entering the interior of the iron detection assembly 9 and affecting the detection sensitivity of its sensing end.

[0025] The iron detection assembly 9 includes a nylon rod 12 and a detection probe 17. The nylon rod 12 is mounted on one side of the second magnetic system 10 via a support frame. The line connecting the two nylon rods 12 is perpendicular to the movement direction of the unloading belt 5, which enables uniform monitoring of the amount of iron impurities adsorbed along the width of the unloading belt 5. This avoids detection deviations caused by excessive iron impurities accumulating on one side while the other side fails to reach the threshold, ensuring the comprehensiveness and accuracy of the detection results.

[0026] The support frame includes a lower support plate 13 and an upper support plate 16. Support rods 19 are fixed to the four corners of the top of the lower support plate 13, and the support rods 19 pass vertically through the support plate 21. Two sets of axially distributed first adjusting nuts are provided on the rods 19, and these two sets of first adjusting nuts abut against the upper and lower sides of the support plate 21, respectively. By tightening or loosening the first adjusting nuts, the distance between the lower support plate 13 and the support plate 21 can be flexibly adjusted, thus providing a basis for subsequent adjustment of the contact pressure of the nylon rod 12.

[0027] The detection probe 17 is installed at the bottom of the upper support plate 16, and the top of the support rod 19 passes through the upper support plate 16. The upper support plate 16 and the lower support plate 13 are located on the upper and lower sides of the support plate 21, respectively. The support rod 19 has two sets of axially distributed second adjusting nuts, which abut against the upper and lower sides of the upper support plate 16, respectively. By tightening or loosening the second adjusting nuts, the height of the upper support plate 16 can be adjusted, providing support for adjusting the distance between the detection probe 17 and the detection bolt 18.

[0028] The top of the nylon rod 12 is equipped with a detection bolt 18 facing the detection probe 17. The detection probe 17 adopts a non-contact displacement sensor, which can monitor the distance change between itself and the detection bolt 18 in real time and accurately capture the position signal change caused by the accumulation of iron impurities. The contact end (bottom) of the nylon rod 12 passes through the support plate 21 and the lower support plate 13 in sequence and forms a sliding fit with the two plates, allowing it to move flexibly up and down in the vertical direction. Its contact end abuts against the inner end face of the unloading belt 5.

[0029] A frustum 20 is provided in the middle of the nylon rod 12, and the diameter of the frustum 20 is larger than the diameter of the main body of the nylon rod 12. The frustum 20 abuts against the upper end surface of the lower support plate 13, limiting the lower limit of the downward movement of the nylon rod 12.

[0030] A spring 14 is fitted around the outer periphery of the nylon rod 12. The upper end of the spring abuts against the lower end face of the support plate 21, and the lower end abuts against the upper end face of the truncated cone 20. The spring force forms a resistance to the upward movement of the nylon rod 12, which ensures the close contact between the nylon rod 12 and the unloading belt 5, and also limits the upper limit of its upward movement.

[0031] When the equipment is in operation, the unloading belt 5 remains stationary, and the second magnetic system 10 and the first magnetic system 8 inside the redirecting roller assembly 7 continuously generate a stable magnetic field. The material to be processed is conveyed to the area below the unloading belt 5 via a matching conveyor belt. Iron impurities mixed in the material are firmly adsorbed onto the outer surface of the unloading belt 5 under the magnetic attraction of the magnetic field. As the material conveying volume increases, iron impurities on the belt surface accumulate continuously. When enough iron impurities are adsorbed onto the surface of the unloading belt 5, these iron impurities overcome the tension of the unloading belt 5 and move towards the second magnetic system 10, thereby forming an upward compressive force on the unloading belt 5. Since the inner end face of the unloading belt 5 is in close contact with the contact end of the nylon rod 12, the compressive force will directly act on the nylon rod 12, pushing the nylon rod 12 to move upward against the elastic force of the spring 14, and the detection bolt 18 above the nylon rod 12 moves closer to the detection probe 17. When the detection probe 17 detects the detection bolt 18, that is, when the distance between the two is reduced to the preset detection threshold, it indicates that the accumulation of iron impurities has reached the threshold. Then a signal is sent, the control cabinet receives the signal, the drive motor 2 is powered on, the unloading belt 5 is started, and the subsequent unloading procedure is initiated.

Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, enabling those skilled in the art to effectively utilize the invention and its modifications.
