Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to a device for conveying and removing iron from bulk materials. Background Art

[0002] When recycling large pieces of material, they are usually crushed. In order to reduce equipment damage, in the existing technology, the large pieces of material are input into a permanent magnetic iron remover before the material is crushed. The iron remover adsorbs the iron products that are difficult to remove from the large pieces of material and removes the iron. The iron-free material then slides into the crusher through the chute.

[0003] The above method often directly introduces a large amount of bulk materials into the permanent magnetic iron remover, causing a large amount of material to accumulate in the permanent magnetic iron remover. Although some iron materials close to the adsorption wall of the permanent magnetic iron remover will be adsorbed on the permanent magnetic iron remover, the iron products far away from the adsorption wall of the permanent magnetic iron remover are easily not adsorbed by gravity and fall out of the permanent magnetic iron remover directly, resulting in poor iron removal effect. The iron products that are not removed still fall into the equipment and cause damage to the equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a bulk material conveying and iron removal device. The specific technical solution is as follows:

[0005] A bulk material conveying and iron removal device includes a bulk material conveying and iron removal device, including a permanent magnetic iron remover, the permanent magnetic iron remover has a conical action tube, the inner side wall of the conical action tube serves as the adsorption surface of the permanent magnetic iron remover for adsorbing iron materials, a plurality of baffles are provided on the inner side of the conical action tube, the top end of the baffle extends toward the top of the conical action tube, the bottom end of the conical action tube extends toward the bottom of the conical action tube, a downwardly inclined buffer plate is provided between two adjacent baffles, a buffer cavity is formed between the buffer plate and the two adjacent baffles and the conical action tube, a discharge gap is provided between the bottom end of the buffer plate and the conical action tube, and non-ferrous materials are discharged from the discharge gap by gravity.

[0006] As an improvement of the above technical solution: it also includes a fixed base, which is fixedly connected to the outside of the permanent magnetic iron remover. The fixed base is fixedly connected to a fixed top plate through a bracket. Multiple groups of moving components are arranged on the fixed top plate, and each group of the moving components is used to drive a buffer plate to move toward its own axis.

[0007] As an improvement of the above technical solution: the moving component includes a hydraulic cylinder, which is fixedly installed on the bottom of the fixed top plate, the top of the buffer plate has a displacement column, and the bottom output rod of the hydraulic cylinder is fixedly connected to the top of the displacement column.

[0008] As an improvement to the above technical solution: a guide sleeve is provided on the surface of the displacement column, and the guide sleeve is connected to the fixed top plate through a fixed support column.

[0009] As an improvement to the above technical solution: a downwardly inclined feed slope is provided at the top of the buffer chamber, and the angle between the feed slope and the horizontal plane is between 30-60 degrees.

[0010] Beneficial effects of the utility model:

[0011] When removing iron products from bulk materials, first, multiple feed ramps are used to feed the bulk materials into the buffer chambers inside the permanent magnetic separators, so that the bulk materials can be evenly dispersed and bulk materials can be avoided from accumulating together inside the permanent magnetic separators. Some iron materials are not directly affected by the adsorption force of the permanent magnetic separators and fall out of the permanent magnetic separators. When the materials are introduced into the buffer chambers, a part of the iron products contained in the flow near the inner wall of the conical action tube will come into contact with the conical action tubes and be adsorbed by the inner side of the conical action tubes. Materials that do not contain iron will fall out of the discharge gap and be transported to the crusher; a part of the logistics away from the inner wall of the conical action tube will hit the buffer plate, causing some of the iron products contained in the material to bounce onto the conical action tube and be adsorbed by the conical action tube, and the iron products contained in the other part of the material will fall from the discharge gap to the side wall of the conical action tube below the buffer plate and be adsorbed. Therefore, this application can effectively prevent some of the materials that are not adsorbed by the permanent magnetic iron remover from falling directly into the crusher, so that the iron products can be effectively removed and the damage to the equipment is reduced.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] Example

[0017] Please refer to Figure 1-Figure 2 , a bulk material conveying and iron removal device, including a permanent magnetic iron remover 2, the permanent magnetic iron remover 2 has a conical action tube 20, the inner side wall of the conical action tube 20 serves as the adsorption surface of the permanent magnetic iron remover 2 for adsorbing iron materials, specifically, the permanent magnetic iron remover 2 can adopt existing technical models including but not limited to FJ-CZ158 or FJ-C128 and other conical permanent magnetic iron removers, a plurality of baffles 21 are provided on the inner side of the conical action tube 20, the top end of the baffle 21 extends toward the top of the conical action tube 20, and the bottom end of the conical action tube 20 extends toward the bottom of the conical action tube 20, specifically, a plurality of baffles 21 are evenly fixedly installed on the inner side wall of the conical action tube 20 of the permanent magnetic iron remover 2, and a buffer plate 3 inclined downward is provided between two adjacent baffles 21, and the surface of the buffer plate is made of rubber material or nickel-based alloy, stainless steel or other materials. Furthermore, the bottom port of the conical action pipe 20 can be aligned with the crusher to facilitate direct transportation of the material in the permanent magnetic iron remover 2 to the crusher.

[0018] Specifically, the angle between the buffer plate 3 and the horizontal plane is between 30-60 degrees. A buffer cavity 200 is formed between the buffer plate 3 and the two adjacent baffles 21 and the conical action tube 20. There is a discharge gap 201 between the bottom end of the buffer plate 3 and the conical action tube 20. Non-ferrous materials are discharged from the discharge gap 201 by gravity.

[0019] In an optional embodiment: it also includes a fixed base 1, which is fixedly connected to the outer side of the permanent magnetic iron remover 2. The fixed base 1 is used to stably support the permanent magnetic iron remover 2 to facilitate material transportation. The fixed base 1 is fixedly connected to a fixed top plate 6 through a bracket. The fixed top plate 6 is arranged directly above the fixed base 1. Multiple groups of moving components are arranged on the fixed top plate 6, and each group of moving components is used to drive a buffer plate 3 to move toward its own axis.

[0020] In an optional embodiment: the moving component includes a hydraulic cylinder 5, which is fixedly installed at the bottom of the fixed top plate 6, and the top of the buffer plate 3 has a displacement column 31, and the bottom output rod of the hydraulic cylinder 5 is fixedly connected to the top of the displacement column 31.

[0021] In an optional embodiment: a guide sleeve 32 is provided on the surface of the displacement column 31, and the guide sleeve 32 is connected to the fixed top plate 6 through a fixed support 33. Specifically, the guide sleeve 32 activates the guiding and limiting effect on the displacement column 31, so that the hydraulic cylinder 5 can stably drive the buffer plate 3 to move in the direction of its own axis.

[0022] Through the cooperation of the guide sleeve 32 and the fixed support 33, the buffer plate 3 can be stably connected to the buffer chamber 200 to buffer the introduced logistics. Specifically, by moving the component, on the one hand, the buffer plate 3 can be controlled to move away from or close to the conical action tube 20 to change the gap size and control the material discharge speed from the buffer chamber 200 according to the size of the material volume. On the other hand, during the discharge process, the gap size can also be adjusted to prevent some logistics from being blocked in the buffer chamber 200 above the buffer plate 3.

[0023] In an optional embodiment, a downwardly inclined feed slope 4 is provided at the top of the buffer chamber 200 , and the angle between the feed slope 4 and the horizontal plane is between 30-60 degrees. The feed slope 4 facilitates the input of bulk materials into the buffer chamber 200 .

[0024] Specifically, when removing iron products from bulk materials, first, the bulk materials are fed into the buffer chambers 200 inside the permanent magnetic iron removers 2 through multiple feed ramps 4, so that the bulk materials can be evenly dispersed, and the bulk flow is prevented from accumulating together inside the permanent magnetic iron remover 2 as much as possible. Some iron materials are not directly affected by the adsorption force of the permanent magnetic iron remover 2 and fall out of the permanent magnetic iron remover 2. When the materials are introduced into the buffer chamber 200, a part of the iron products contained in the flow near the inner wall of the conical action tube 20 will come into contact with the conical action tube 20 and be adsorbed by the inner side of the conical action tube 20. The materials without iron will fall out from the discharge gap 201 and be transported to the crusher.

[0025] A portion of the logistics away from the inner wall of the conical action tube 20 will collide with the buffer plate 3, so that part of the iron contained in the material will bounce onto the conical action tube 20 and be adsorbed by the conical action tube 20, and part of the iron products contained in the material will fall from the discharge gap 201 to the side wall of the conical action tube 20 below the buffer plate 3 and be adsorbed. Therefore, this application can effectively prevent part of the material from not being adsorbed by the permanent magnetic iron remover 2 and falling directly into the crusher, so that the iron products can be effectively removed and the damage to the equipment is reduced.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
