Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to an iron removal equipment for ore dressing and screening. Background Art

[0002] In the mineral processing process, the ore needs to be crushed, screened and other treatments to remove impurities and materials that do not meet the requirements. Among them, the removal of ferromagnetic impurities is an important link, because these impurities will affect the subsequent mineral processing effect and product quality.

[0003] In the prior art, the traditional iron removal method usually adopts a magnetic iron remover to adsorb the metal impurities in the material. The working principle of the existing magnetic iron remover is mostly to install a permanent magnet in the middle of the conveyor belt. When the metal material passes by, it will be adsorbed on the conveyor belt. The operation of the conveyor belt drives the metal material to move. When the metal material moves to leave the attraction range of the permanent magnet, the impurities are thrown out under the action of inertia to achieve a self-unloading effect. However, most traditional iron removers lack protective devices. When unloading, the material is thrown to one side due to inertia, which can easily injure the staff passing by. Therefore, the utility model proposes an iron removal equipment for mineral processing and screening to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an iron removal device for ore dressing and screening.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A deironing device for mineral processing and screening comprises two vertical plates, two symmetrically arranged driving rollers are commonly arranged between the two vertical plates, a conveyor belt is commonly installed between the two driving rollers, both ends of the two vertical plates are commonly fixedly connected with a fixed plate, the side walls at opposite ends of the two fixed plates are each provided with a protective mechanism for protecting unloaded materials, the protective mechanism comprises two symmetrically arranged mounting blocks fixedly connected to the side walls of the fixed plates, a cross bar is commonly rotatably connected between the two mounting blocks, a buffer plate is fixedly sleeved on the cross bar, and the opposite ends of the two fixed plates are each provided with a buffer mechanism for buffering the buffer plate on the same side.

[0007] Preferably, the buffer mechanism includes a fixed block fixedly connected to the side wall of the fixed plate, the fixed block is provided with a first groove, a rotating rod is rotatably connected in the first groove, a sliding groove is provided on the side wall of the buffer plate, a sliding block is slidably connected in the sliding groove, a second groove is provided at the end of the sliding block, and the rotating rod is rotatably connected in the second groove at one end away from the first groove.

[0008] Preferably, a limiting rod is fixedly connected between the inner walls at both ends of the two sliding grooves, and the two limiting rods pass through the two sliding blocks respectively and are slidably connected thereto.

[0009] Preferably, the upper ends of the two sliding blocks are elastically connected to the inner wall of the sliding groove on the same side through springs, and the two springs are respectively sleeved on the two limiting rods.

[0010] Preferably, a transverse plate is fixedly connected to the side walls of the two fixed plates, and two symmetrically arranged electric push rods are fixedly connected to the lower ends of the two transverse plates.

[0011] Preferably, a permanent magnet is fixedly connected between the two vertical plates, and the permanent magnet is located in the middle of the conveyor belt.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting up a protective mechanism, when unloading, metal impurities are thrown to both sides under the action of inertia. Under the action of the buffer plate, the material is blocked to prevent the material from being thrown far away and posing a threat to the staff.

[0014] 2. By setting up a buffer mechanism, when unloading, the thrown metal materials can contact the buffer plate. The buffer plate is impacted and can rotate with the cross bar as the axis to move closer to the fixed plate. At this time, the buffer plate pushes the rotating rod to rotate, and the rotating rod can push the slider to move in the slide groove, and the extrusion spring contracts, which can achieve buffering of the buffer plate and the material, avoiding damage to the buffer plate caused by a large impact force.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] Reference Figure 1-4 A deironing device for mineral processing and screening comprises two vertical plates 3, two symmetrically arranged driving rollers 8 are arranged between the two vertical plates 3, a conveyor belt 4 is installed between the two driving rollers 8, both ends of the two vertical plates 3 are fixedly connected with a fixed plate 1, and the side walls at opposite ends of the two fixed plates 1 are provided with a protective mechanism for protecting the unloaded materials, the protective mechanism comprises two symmetrically arranged mounting blocks 15 fixedly connected to the side walls of the fixed plates 1, a cross bar 16 is rotatably connected between the two mounting blocks 15, and a buffer plate 7 is fixedly sleeved on the cross bar 16. It should be noted that a driving motor needs to be installed on the device to drive the rotation of the driving rollers 8.

[0022] In the utility model, a buffer mechanism for buffering the buffer plate 7 on the same side is provided at the opposite ends of the two fixed plates 1, and the buffer mechanism includes a fixed block 14 fixedly connected to the side wall of the fixed plate 1, a first groove is provided on the fixed block 14, a rotating rod 13 is rotatably connected in the first groove, a sliding groove 9 is provided on the side wall of the buffer plate 7, a slider 11 is slidably connected in the sliding groove 9, a second groove is provided at the end of the slider 11, and the end of the rotating rod 13 away from the first groove is rotatably connected in the second groove, and a limiting rod 12 is fixedly connected between the inner walls at both ends of the two sliding grooves 9, and the two limiting rods 12 passes through the two sliders 11 respectively and is slidably connected thereto. The upper ends of the two sliders 11 are elastically connected to the inner wall of the same side slide groove 9 through springs 10. The two springs 10 are respectively mounted on two limit rods 12. The setting of the limit rods 12 can limit the sliders 11 and improve the stability of the movement of the sliders 11. It should be noted that the buffer plate 7 is inclined in design, which can better catch the thrown materials and facilitate the sliding of the materials. Buffer pads are arranged on the side walls of the opposite ends of the buffer plates 7 on both sides. The material of the cushion pads is sponge, which can greatly reduce the impact force and achieve the effect of buffering and noise reduction.

[0023] In the utility model, a horizontal plate 2 is fixedly connected to the side walls of the two fixed plates 1, and two symmetrically arranged electric push rods 6 are fixedly connected to the lower ends of the two horizontal plates 2. A permanent magnet 5 is fixedly connected between the two vertical plates 3, and the permanent magnet 5 is located in the middle part of the conveyor belt 4. The four electric push rods 6 are linked by a synchronizer, so that the telescopic ends of the four electric push rods 6 can move synchronously.

[0024] When the utility model is used, the device is first installed above the conveyor, and then the driving roller 8 rotates to drive the conveyor belt 4 to rotate. The conveyor starts to drive the material to move and transport the material. When passing under the conveyor belt 4, the permanent magnet 5 can adsorb the metal impurities in the material and make it adsorbed on the surface of the conveyor belt 4. The operation of the conveyor belt 4 can drive the adsorbed metal material to move. When the metal material follows the conveyor belt 4 to move away from the adsorption range of the permanent magnet 5, automatic unloading is completed. During the unloading process, due to inertia, the metal material is thrown in the moving direction of the conveyor belt 4, and the buffer plate 7 can block the metal impurities. The metal material is prevented from being thrown far away and causing danger. When the metal material contacts the buffer plate 7, the impact on the buffer plate 7 causes the buffer plate 7 to rotate with the cross bar 16 as the axis. The rotation of the buffer plate 7 squeezes the rotating rod 13 to rotate, thereby pushing the slider 11 to move in the slide groove 9 and squeezing the spring 10. The spring 10 can buffer the buffer plate 7 and the thrown metal material to avoid damage to the buffer plate 7 caused by a large impact force. When the metal material to be adsorbed is large, the telescopic end of the electric push rod 6 can be driven to extend, driving the cross plate 2 and the device as a whole to move upward, adjusting the distance between the device and the material, and avoiding the machine from getting stuck.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
