[0040] At present, the devices used to remove debris from non-iron ore bulk materials can only remove non-magnetic debris such as plastic bags and wire mesh in the material flow, but cannot remove magnetic debris in the material flow. Since magnetic debris is often submerged at the bottom of the material flow, it can only be cleaned frequently by manual labor, which is time-consuming and labor-intensive.

[0041] To address this problem, the present invention provides a rotary gear magnetic debris removing device, in which a first debris removing component and a second debris removing component are simultaneously provided. The first debris removing component and the second debris removing component can work simultaneously, thereby removing magnetic debris while removing non-magnetic debris, thereby improving the debris cleaning efficiency.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] The embodiment of the present invention provides a rotating gear magnetic suction type debris removal device, which may include: a first debris removal component, a second debris removal component and a support frame. The first debris removal component is used to remove magnetic debris in the material; the second debris removal component is used to remove non-magnetic debris in the material; the support frame is used to support the first and second debris removal components.

[0044] Wherein: the first impurity removal component comprises: a magnetic structure. The second impurity removal component comprises: a rotatable anti-magnetic outer cylinder, and a plurality of anti-magnetic hook teeth arranged on the outer surface of the anti-magnetic outer cylinder, the anti-magnetic hook teeth are used to hook out non-magnetic impurities in the falling materials.

[0045] The magnetic structure is located inside the anti-magnetic outer cylinder, and is used to form an adsorption area on the anti-magnetic outer cylinder in contact with the falling material, so as to adsorb the magnetic debris in the falling material on the outer surface of the anti-magnetic outer cylinder. As the anti-magnetic outer cylinder rotates, the non-magnetic debris hooked by the anti-magnetic hook teeth and the magnetic debris adsorbed on the anti-magnetic outer cylinder fall into the debris collection area.

[0046] In the embodiments of the present invention, magnetic debris refers to substances that can be directly or indirectly absorbed by ferromagnets, such as bolts, wires, iron blocks, welding rods and other steel debris. The non-magnetic debris refers to debris that cannot be directly or indirectly absorbed by ferromagnets, such as plastic bags, ribbons, gloves and other soft debris. Anti-magnetic means not being affected by the magnetic field generated by the magnetic structure, that is, shielding the magnetic field generated by the magnetic structure. For example, the anti-magnetic outer cylinder will not be magnetic due to the magnetic field generated by the magnetic structure, and the anti-magnetic hook teeth will not be magnetic due to the magnetic field generated by the magnetic structure.

[0047] By setting a magnetic structure inside the anti-magnetic outer cylinder, an adsorption area is formed in the area on the anti-magnetic outer cylinder that contacts the falling material, so that the magnetic debris in the falling material can be adsorbed on the outer surface of the anti-magnetic outer cylinder. In this way, as the anti-magnetic outer cylinder rotates, the non-magnetic debris hooked by the anti-magnetic hook teeth and the magnetic debris adsorbed on the anti-magnetic outer cylinder fall into the debris collection area, so that the magnetic debris can be removed while the non-magnetic debris is still removed, without the need to manually clean the magnetic debris, reducing the workload and improving the efficiency of debris removal.

[0048] Figure 1 This is a perspective view of the three-dimensional structure of a rotary gear magnetic suction type debris removal device in an embodiment of the present invention. Figure 2 1 is a cross-sectional view of a rotary gear magnetic suction type debris removal device according to an embodiment of the present invention, taken along a direction perpendicular to the axial direction. Figure 3 1. A top view of a rotary gear magnetic suction type debris removing device according to an embodiment of the present invention.

[0049] Reference Figures 1 to 3In one embodiment of the present invention, the first impurity removal component may include: a magnetic structure 111, a support shaft 112 and an anti-magnetic inner cylinder 113.

[0050] Among them, the support shaft 112 is fixed on the support frame 10, and the anti-magnetic inner cylinder 113 is located inside the anti-magnetic outer cylinder 121 and is fixedly connected to the support shaft 112. The magnetic structure 111 is fixed inside the anti-magnetic outer cylinder 121 through the anti-magnetic inner cylinder 113. The second impurity removal component may include: an anti-magnetic outer cylinder 121 and a plurality of anti-magnetic hook teeth 122 arranged on the outer surface of the anti-magnetic outer cylinder 121. The anti-magnetic outer cylinder 121 is sleeved outside the anti-magnetic inner cylinder 113 and rotates independently, and the anti-magnetic hook teeth 122 can hook non-magnetic debris from the falling material 20.

[0051] In a specific implementation, the magnetic structure 111 can be implemented by an electromagnet or a permanent magnet. The magnetic structure 111 is fixed inside the magnetic shielding outer cylinder 121 through the magnetic shielding inner cylinder 113, that is, the position of the magnetic structure 111 inside the magnetic shielding outer cylinder 121 is fixed, thereby forming an adsorption area in the area where the magnetic shielding outer cylinder 121 contacts the falling material 20. At this time, even if the magnetic shielding outer cylinder 121 rotates, the position of the adsorption area remains unchanged, thereby the magnetic impurities in the falling material 20 can be adsorbed at different positions on the outer wall of the magnetic shielding outer cylinder 121, rather than adsorbing the magnetic impurities at the same position on the outer wall of the magnetic shielding outer cylinder 121, thereby avoiding the accumulation of magnetic impurities and affecting the impurity removal effect.

[0052] In a specific implementation, the magnetic structure 111 can extend along the axial direction A of the anti-magnetic inner cylinder 113, thereby forming an adsorption area extending along the axial direction A of the anti-magnetic inner cylinder 113 in the area where the anti-magnetic outer cylinder 121 contacts the falling material 20, thereby increasing the size of the adsorption area, improving the adsorption efficiency, and also improving the impurity removal efficiency.

[0053] In a specific implementation, the magnetic structure 111 may be a magnetic structure with uniform magnetic force distribution. For example, the magnetic strength of the magnetic structure 111 is the same at all locations and is above 2500 GS.

[0054] In one embodiment, the magnetic structure 111 may include: a first magnetic portion and a second magnetic portion distributed along an axial direction A perpendicular to the anti-magnetic inner cylinder, the distance from the first magnetic portion to the debris collection area is greater than the distance from the second magnetic portion to the debris collection area; the magnetic force of the first magnetic portion is greater than the magnetic force of the second magnetic portion.

[0055] Taking the cylindrical structure composed of the magnetic structure 111 and the anti-magnetic inner cylinder 113 as an example, the first magnetic part and the second magnetic part are distributed along the circumferential direction of the cylindrical structure. Compared with the second magnetic part, the first magnetic part is closer to the feed inlet and away from the debris collection area, so that the adsorption area forms a stronger magnetic force near the feed inlet, and a weaker magnetic force near the debris collection area. When the anti-magnetic outer cylinder 121 rotates from away from the debris collection area to close to the debris collection area, the magnetic debris adsorbed on the outer wall of the anti-magnetic outer cylinder 121 can be adjusted from a strong adsorption state to a weak adsorption state, so that it can easily fall into the debris collection area when rotating to the top of the debris collection area, avoiding the accumulation caused by the magnetic debris not falling off in time, and further improving the impurity removal efficiency. For example, the magnetic force of the first magnetic part can be set to be above 2500GS, and the magnetic force of the second magnetic part can be set to be around 1000GS.

[0056] In other embodiments, the magnetic structure 111 may be configured to consist of three or more magnetic parts with gradually varying magnetic strengths, thereby allowing the adsorption area to consist of multiple areas with gradually varying magnetic strengths, thereby allowing the adsorption state of magnetic debris adsorbed on the outer wall of the anti-magnetic outer cylinder 121 to change slowly, thereby better avoiding accumulation caused by magnetic debris not falling off in time.

[0057] In a specific implementation, the magnetic structure 111 can be fixed inside the anti-magnetic outer cylinder 121 in a variety of ways.

[0058] In one embodiment of the present invention, the antimagnetic inner cylinder 113 may include a first inner cylinder plate and a second inner cylinder plate, the first inner cylinder plate and the second inner cylinder plate have a gap, and the magnetic structure 111 is located in the gap between the first inner cylinder plate and the second inner cylinder plate.

[0059] Specifically, the first inner cylinder plate and the second inner cylinder plate can both be cylindrical stainless steel plates, and one end of the two are welded and connected, and the other end has an annular spacing, and the magnetic structure 111 is arranged in the annular spacing. At this time, the magnetic structure 111 can also be arc-shaped, and form a cylindrical shape with the cylindrical first inner cylinder plate and the second inner cylinder plate. The two cylindrical inner cylinder plates of the antimagnetic inner cylinder body 113 tightly clamp the magnetic structure 111 to keep it fixed. The cylindrical structure composed of the magnetic structure 111 and the antimagnetic inner cylinder body 113 has a certain gap with the antimagnetic outer cylinder body 121, so as not to interfere with the rotation of the antimagnetic outer cylinder body 121.

[0060] In other embodiments, the first inner cylinder plate and the second inner cylinder plate may also be stainless steel plates of other shapes, such as pentagons, hexagons, etc., without limitation here, as long as they can fix the magnetic structure 111 and do not interfere with the rotation of the anti-magnetic outer cylinder 121.

[0061] In a specific implementation, the first impurity removal assembly may further include an inner connecting flange and a fixed support seat. There are two fixed support seats, which are respectively arranged at two symmetrical ends of the support shaft 112. The support shaft 112 is supported by the support frame through the two fixed support seats. There are also two inner connecting flanges, and the first inner cylinder plate and the second inner cylinder plate are fixed on the support shaft 112 through the two inner connecting flanges.

[0062] In a specific implementation, the anti-magnetic outer cylinder 121 is sleeved outside the structure composed of the magnetic structure 111 and the anti-magnetic inner cylinder 113, and can be made of anti-magnetic materials (such as stainless steel plates). The shape of the anti-magnetic outer cylinder 121 can be the same as the structure composed of the magnetic structure 111 and the anti-magnetic inner cylinder 113, as long as the anti-magnetic outer cylinder 121 can rotate independently.

[0063] For example, when the magnetic structure 111 and the antimagnetic inner cylinder 113 form a cylindrical structure, the antimagnetic outer cylinder 121 can be set to be a cylindrical structure, and the diameter of the antimagnetic outer cylinder 121 is greater than the diameter of the cylindrical structure formed by the magnetic structure 111 and the antimagnetic inner cylinder 113. When the magnetic structure 111 and the antimagnetic inner cylinder 113 form a pentagonal cylindrical structure, the antimagnetic outer cylinder 121 can also be set to be a pentagonal cylindrical structure.

[0064] In a specific implementation, the second impurity removal assembly may further include: an external connection flange, a bearing seat body and a bearing. The magnetic-proof outer cylinder 121 is connected to the bearing seat body through the external connection flange, and the bearing seat body is supported on the support shaft 112 through the bearing, so that it can rotate around the support shaft 112.

[0065] In a specific implementation, the antimagnetic hook teeth on the antimagnetic outer cylinder 121 can be divided into two or more rows of hook tooth groups. Each of the two or more rows of hook tooth groups is distributed along the axis perpendicular to the antimagnetic outer cylinder, and each row of hook tooth groups includes two or more antimagnetic hook teeth distributed along the axis of the antimagnetic outer cylinder.

[0066] Specifically, refer to Figure 1 and Figure 2 Taking the anti-magnetic outer cylinder 121 as a cylindrical structure as an example, each hook tooth group is evenly arranged along the circumference of the cylindrical structure. The number of hook tooth groups is usually greater than or equal to 10 groups, for example, 12 rows of hook tooth groups can be set. The anti-magnetic hook teeth of each row of hook tooth groups are distributed along the axial direction A of the anti-magnetic outer cylinder 121, thereby evenly removing impurities from the falling material 20.

[0067] In some embodiments, two adjacent rows of hook teeth may be arranged in a relatively staggered manner, so that they can contact the falling material in a relatively staggered manner, and can remove debris from different positions of the material, thereby improving the debris removal effect.

[0068] In a specific implementation, the anti-magnetic hook teeth 122 are arc-shaped hook teeth, the first end of which is connected to the outer surface of the anti-magnetic outer cylinder 121, and the second end is bent toward the outer surface of the anti-magnetic outer cylinder 121 in a clockwise direction. The arc-shaped hook teeth can increase the contact area between the material 20 and the anti-magnetic hook teeth 122, and the anti-magnetic hook teeth 122 gradually become thinner from the first end to the second end, which helps to hook out non-magnetic debris more thoroughly and improve the cleanliness of the material 20. At this time, the anti-magnetic hook teeth 122 in the adsorption area are bent against the falling direction of the material 20, so that when the material 20 falls and contacts the anti-magnetic hook teeth 122, the non-magnetic debris in the falling material 20 will be hooked on the anti-magnetic hook teeth 122, and the magnetic debris will be adsorbed between the anti-magnetic hook teeth 122, thereby achieving the purpose of removing non-magnetic debris.

[0069] In actual application, as the anti-magnetic outer cylinder 121 rotates, magnetic debris adsorbed on the surface of the anti-magnetic outer cylinder 121 enters the non-adsorption area from the adsorption area. At the boundary between the adsorption area and the non-adsorption area, magnetic debris often accumulates due to the sudden disappearance of magnetic force.

[0070] In one embodiment of the present invention, in order to reduce the accumulation of magnetic debris at the boundary between the adsorption zone and the non-adsorption zone, a debris blocker can be provided at the second end of the anti-magnetic hook teeth 122 in each row of hook tooth groups. The debris blocker extends along the distribution direction of the anti-magnetic hook teeth 122 in the same hook tooth group, that is, along the axial direction of the anti-magnetic outer cylinder 121. The debris blocker can be implemented by steel bars extending along the axial direction of the anti-magnetic outer cylinder 121. The presence of the debris blocker can make the magnetic debris fall off from the surface of the anti-magnetic outer cylinder when there is a lot of magnetic debris accumulation, thereby reducing the workload of manually removing the accumulation and further improving the efficiency of debris removal.

[0071] In a specific implementation, the length and curvature of the anti-magnetic hook tooth 122 match the position of the debris collection area and the material transmission speed. The length and curvature of the anti-magnetic hook tooth 122 (that is, the curvature of the anti-magnetic hook tooth 122) are based on the principle that the debris cannot fall off under the action of its own weight in the non-adsorption area. The larger the curvature of the anti-magnetic hook tooth 122, the greater the degree of curvature of the anti-magnetic hook tooth 122. At this time, the longer the length of the anti-magnetic hook tooth 122, the greater the distance that the non-magnetic debris can be carried and moved by the anti-magnetic hook tooth 122 after being hooked on the anti-magnetic hook tooth 122. In this way, the distance between the debris collection area and the feed inlet can be farther. When the distance between the debris collection area and the feed inlet is close, the curvature of the anti-magnetic hook tooth 122 can be reduced, thereby shortening the distance that the non-magnetic debris is carried and moved by the anti-magnetic hook tooth 122.

[0072] In a specific implementation, the size of the magnetic structure 111 can be set according to factors such as the contact area between the falling material 20 and the anti-magnetic outer cylinder 121 and the rotation direction of the anti-magnetic outer cylinder 121, thereby changing the size of the adsorption area so that the adsorption area at least includes the contact area between the falling material 20 and the anti-magnetic outer cylinder 121.

[0073] In a specific implementation, the anti-magnetic outer cylinder 121 can rotate in a clockwise direction around the support shaft 112. At this time, when the position of the debris collection area remains unchanged, it is necessary to set the magnetic structure 111 to at least cover 50% of the inner wall area of ​​the anti-magnetic outer cylinder 121, so that the magnetic debris adsorbed on the outer surface of the anti-magnetic outer cylinder 121 can fall off to the debris collection area below the anti-magnetic outer cylinder 121. Taking the arc-shaped magnetic structure 111 as an example, at this time, the size of the magnetic structure 111 along the circumference of the anti-magnetic outer cylinder 121 is at least equal to half of the circumference of the anti-magnetic outer cylinder 121.

[0074] In another embodiment of the present invention, the magnetic shielding outer cylinder 121 can be rotated in a counterclockwise direction (i.e. Figure 2 The magnetic structure 111 is provided with a smaller size so that the magnetic debris adsorbed on the outer surface of the anti-magnetic outer cylinder 121 can fall off to the debris collection area below the anti-magnetic outer cylinder 121.

[0075] Specifically, the magnetic structure 111 covers 25% to 50% of the inner wall area of ​​the anti-magnetic outer cylinder 121. At this time, an adsorption area and a non-adsorption area are formed on the anti-magnetic outer cylinder 121 in the area in contact with the falling material 20, so that as the anti-magnetic outer cylinder 121 rotates, the magnetic debris adsorbed on the anti-magnetic outer cylinder 121 enters the non-adsorption area from the adsorption area, and can fall off from the anti-magnetic outer cylinder 121.

[0076] In a specific implementation, the rotation speed of the anti-magnetic outer cylinder 121 can be adjusted to improve the impurity removal efficiency. In one embodiment, the rotation speed of the anti-magnetic outer cylinder 121 can be set to be lower than the falling speed of the material 20, so that when the material 20 falls and contacts the anti-magnetic outer cylinder 121 and the anti-magnetic hook teeth 122, the slow rotation of the anti-magnetic outer cylinder 121 can make the anti-magnetic outer cylinder 121 and the anti-magnetic hook teeth 122 more fully contact the falling material 20, so that the impurities can be removed more thoroughly. For example, the rotation speed of the anti-magnetic outer cylinder 121 can be set to 3 rpm to 6 rpm.

[0077] In a specific implementation, the support frame 10 can support the first impurity removal component and the second impurity removal component. Specifically, the support frame 10 can include a first support unit and a second support unit, and the two support units are arranged along the axial direction A of the magnetic shielding outer cylinder 121. Each support unit can be composed of a crossbeam square tube and three vertical square tubes below it, and the four square tubes of the same support unit form a gate-shaped structure, and the three vertical square tubes are fixed on the foundation ground.

[0078] In one embodiment of the present invention, referring to Figure 1 The rotary gear magnetic suction type debris removal device may further include a driving assembly 13, which is located on the support frame 10 and connected to the second debris removal assembly, and is used to drive the anti-magnetic outer cylinder 121 to rotate around the support shaft 112.

[0079] Specifically, the driving assembly may include a motor, a reducer, a support, and a transmission sprocket. Among them, the motor and the reducer can be implemented in an integrated machine. The transmission sprocket may include: a motor reducer sprocket and a large sprocket. The motor reducer is fixed to a support frame 10 on one side through a support, and the drive shaft of the motor reducer is connected to the motor reducer sprocket. The large sprocket is installed on the bearing seat body of the anti-magnetic outer cylinder 121, and the motor reducer sprocket and the large sprocket are driven by a chain. During use, the motor is started, and the motor drives the reducer to move. The reducer sprocket rotates together with the large sprocket installed on the bearing seat body of the anti-magnetic outer cylinder 121 through the chain. After the reducer is running, it drives the anti-magnetic hook teeth 122 of the anti-magnetic outer cylinder 121 to rotate.

[0080] When the motor and reducer are implemented in an integrated machine, only sprocket drive can be used externally without using other transmission mechanisms, thereby making the structure of the drive component more compact, easier to arrange, more stable in performance, and less maintenance required.

[0081] In one embodiment of the present invention, referring to Figure 1 and Figure 2 The rotary gear magnetic suction type debris removing device may further include: a shell 14.

The first impurity removal component and the second impurity removal component are located in the housing 14. The housing 14 has a feed port 14a. The housing 14 has a cavity inside, and the first impurity removal component and the second impurity removal component are both located in the cavity of the housing 14. One end of the cavity serves as the feed port 14a, which is used to provide materials to the rotary gear magnetic suction type impurity removal device.

[0082] Specifically, the housing 14 may include an upper box and a lower box. The upper box may be divided into a left box and a right box. The boxes are flange-connected for easy maintenance. A dust curtain may be provided at the feed inlet 14a to prevent dust from spilling out. A material collection area and a debris collection area may be provided below the lower box. The material collection area is used to collect materials after debris removal, and the debris collection area is used to collect removed debris.

[0083] In one embodiment of the present invention, referring to Figure 2 The rotary gear magnetic suction type debris removal device may further include: a scraping assembly 15. The scraping assembly 15 may include a plurality of comb teeth distributed along the axial direction A of the anti-magnetic outer cylinder 121, and the first end of the comb teeth contacts the outer wall of the anti-magnetic outer cylinder 121 to clean the debris remaining in the anti-magnetic outer cylinder 121.

[0084] Specifically, the scraping assembly 15 may include a comb plate assembly and a mounting base. The comb plate assembly may be cut from a stainless steel plate into a comb shape. The comb plate may have a reinforcing rib plate and a reinforcing angle steel. The mounting base and the comb plate assembly may be connected by bolts, and the mounting base may be welded inside the housing 14. The comb teeth on the comb plate are distributed along the axial direction A of the antimagnetic outer cylinder 121, and each comb tooth extends from the mounting base to the direction of the antimagnetic outer cylinder 121.

[0085] The end of the first end of the comb teeth contacts the outer wall of the anti-magnetic outer cylinder 121, and the hardness of the comb teeth is less than the hardness of the anti-magnetic hook teeth 122. By providing the scraping assembly 15, the comb teeth can scrape the non-magnetic debris and magnetic debris wrapped around the outer wall of the anti-magnetic outer cylinder 121 from the outer wall of the anti-magnetic outer cylinder 121 to the debris collection area, thereby effectively ensuring the material removal rate.

[0086] In one embodiment of the present invention, the rotary gear magnetic suction type debris removal device may further include: a transmission component. The transmission component cooperates with the feed inlet 14a and is used to provide materials to the rotary gear magnetic suction type debris removal device through the feed inlet 14a.

[0087] In the specific implementation, refer to Figure 2 The transmission component includes: a transmission belt 161 and a head roller 162. The material is transported to the head roller 162 through the transmission belt 161 and thrown from the head roller 162 into the feed port 14a.

[0088] In practical applications, the first impurity removal assembly and the second impurity removal assembly only need to be installed in front of the head drum 162, and the internal components thereof can be covered by the shell 14, which is convenient for installation and removal and saves construction costs.

[0089] In other embodiments, the transmission component may not be provided, and the first impurity removal component and the second impurity removal component may be installed on the blanking barrel. The blanking barrel also has an inlet, and the material put into the inlet can directly fall on the anti-magnetic outer cylinder 121, so that the anti-magnetic hook teeth 122 on the anti-magnetic outer cylinder 121 and the magnetic structure inside the anti-magnetic outer cylinder 121 can achieve impurity removal.

[0090] In one embodiment of the present invention, the rotary gear magnetic suction type debris removal device may further include: a material regularization component 17. The material regularization component 17 is located in the housing 14 and above the feed port 14a, and is used to regularize the material distribution on the transmission component.

[0091] Specifically, the material regularization component 17 can be composed of a guide gallows, a guide adjustment column and a diverter. The guide gallows is fixed on the shell 14 and connected to the diverter through the guide adjustment column. The diverter has a guide port, which is set toward the material. For example, the diverter can be implemented by a triangular plow. When in use, the guide port of the diverter can contact the material, and then the material at the feed inlet 14a is changed from a flat column to a flat shape, so that the material concentrated in the center of the transmission belt 161 is evenly distributed in the side cross-section of the entire transmission belt 161, thereby increasing the contact area between the material and the anti-magnetic outer cylinder 121, so that the impurities in the material can be removed to the maximum extent, further improving the impurity removal efficiency and effect.

[0092] Furthermore, an elastic connection may be provided between the material organizing component 17 and the shell 14 , so that when the material impacts the diverter, the elastic connection allows a certain buffer to exist between the material organizing component 17 and the material, thereby avoiding damage to the material organizing component 17 .

[0093] In one embodiment of the present invention, the rotary gear magnetic suction type debris removal device may further include: a drop hopper 141. The drop hopper 141 may be arranged below the housing 14, corresponding to the position of the material collection area, and the drop hopper 141 may be used to collect the material after the debris is removed, so as to facilitate timely removal of the material after the debris is removed.

[0094] In one embodiment of the present invention, the rotary gear magnetic suction type debris removal device may further include: a debris drop bucket 142. The debris drop bucket 142 may be arranged below the housing 14, corresponding to the position of the debris collection area, and the debris drop bucket 142 may be used to collect the removed debris, thereby facilitating timely removal of the removed debris.

[0095] In a specific implementation, the material drop hopper 141 and the debris drop hopper 142 can be connected to the lower box of the shell 14. A manhole door can be provided on the lower box of the shell 14 to facilitate observation of the conditions in the material drop hopper 141 and the debris drop hopper 142 to avoid affecting the debris removal efficiency.

[0096] In some embodiments, a vibrator may be provided outside the side wall 141a for receiving materials on the hopper 141. By providing the vibrator, the materials accumulated on the side wall 141a for receiving materials can be vibrated into the hopper 141, thereby preventing the materials from accumulating on the side wall 141a for receiving materials and causing the materials to be scattered out of the material collection area, thereby avoiding material waste and affecting the impurity removal efficiency.

[0097] The working process of the rotary gear magnetic suction type debris removal device in the embodiment of the present invention is described as follows:

[0098] When in use, the transmission belt 161 runs first, and then the electric control system can control the motor reducer in the drive assembly to drive the anti-magnetic outer cylinder 121 to rotate through the transmission chain. The material 20 conveyed by the transmission belt 161 is evenly distributed after passing through the material regularization assembly 17, and impacts the anti-magnetic outer cylinder 121 and the anti-magnetic hook teeth 122. At this time, magnetic debris such as ironware in the material 20 will be adsorbed on the outer wall of the anti-magnetic outer cylinder 121 between the anti-magnetic hook teeth 122 by the internal magnetic structure 111 of the anti-magnetic outer cylinder 121, and non-magnetic debris will be hooked out by the anti-magnetic hook teeth 122, and the material will fall into the drop hopper 141 along the anti-magnetic outer cylinder 121. As the anti-magnetic outer cylinder 121 continues to rotate, the magnetic debris adsorbed on the outer wall of the anti-magnetic outer cylinder 121 will gradually break away from the adsorption effect of the magnetic structure 111 and fall into the debris bucket 142, and the non-magnetic debris hooked by the anti-magnetic hook teeth 122 will also fall off from the anti-magnetic hook teeth 122 under the action of gravity and fall into the debris bucket 142.

[0099] When the anti-magnetic outer cylinder 121 rotates to contact the scraping assembly 15, the comb teeth on the scraping assembly 15 can scrape the debris remaining on the anti-magnetic outer cylinder 121 and the anti-magnetic hook teeth 122 into the debris bucket 142, thereby completing the entire process of removing iron debris.

[0100] The rotary gear magnetic suction debris removing device in the embodiment of the present invention can remove magnetic debris while removing non-magnetic debris, thereby reducing the workload of manual cleaning of magnetic debris and improving the debris cleaning efficiency. It is suitable for removing impurities from materials such as coal, coke, and limestone, and can be widely used in bulk material conveying systems in large and medium-sized thermal power plants, steel mills, and chemical plants.

[0101] In addition, by adopting the scheme of the present invention, the anti-magnetic outer cylinder and the anti-magnetic inner cylinder rotate in combination, which can realize automatic separation, cleaning and discharge of debris without human intervention, reducing manual workload and improving the efficiency and effect of debris removal.

[0102] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
