Description

Technical Field

[0001] This utility model relates to the field of dry ore sorting technology, and is mostly used for dry pre-sorting and waste disposal after coarse and fine crushing of ore. Specifically, it relates to a multi-scenario quick-assembly dry sorting belt conveyor. Background Technology

[0002] Dry separation belt conveyors for coarse and fine ore crushing are widely used mineral processing equipment. Their working principle is as follows:

[0003] When the crushed material is transported to the magnetic drum by the conveyor belt, the non-magnetic substances mixed in the material are automatically unloaded at the front end of the magnetic drum, while the material with a high iron content is attracted by the strong magnetic field and continues to move forward with the conveyor belt. After being freed from the magnetic field, it falls automatically to another conveying device by inertia, thus realizing the separation of magnetic and non-magnetic materials.

[0004] Most dry-separation belt conveyors use semi-magnetic drums, installed at the head of the conveyor on-site. The magnetic field strength is typically customized based on the material particle size and grade conditions at the site. Currently, the magnetic field strength and magnetic system arrangement of the drums are fixed structures. When the material particle size, grade, and other feeding conditions change, the magnetic system and other structures of the equipment cannot be flexibly adjusted, resulting in very low applicability and inconvenience for replacement. Furthermore, the current head drive drum uses a semi-shaft structure, where the magnetic system is fixed after being adjusted to a certain angle. The outer cylinder rotates to drive the conveyor belt to transport and separate materials, resulting in poor stress distribution on the drum and high drive power.

[0005] To address the aforementioned problems, this utility model designs and manufactures a multi-scenario quick-installation dry sorting belt conveyor to overcome the above-mentioned defects. Summary of the Invention

[0006] To address the problems existing in the prior art, this utility model provides a multi-scenario quick-assembly dry sorting belt conveyor, which allows for convenient adjustment of the internal magnetic system through flexible disassembly of the drum skin, enabling flexible replacement and combination of some components to adapt to various material scenarios, while also greatly reducing the rotational resistance of the magnetic sorting roller.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-scenario quick-installation dry sorting belt conveyor, including a magnetic sorting roller, which enables the separation of magnetic and non-magnetic materials;

[0008] The magnetic sorting roller includes a main shaft, and the main shaft is provided with two cylindrical end caps with a certain distance between them. The cylindrical end caps are rotatably connected to the main shaft through bearings.

[0009] A magnetic system assembly is fixed on the main shaft located between the two cylinder end caps;

[0010] The main shaft is provided with a cylindrical shell, and a positioning flange is provided at each of the two ends of the inner side of the cylindrical shell. The positioning flange is connected to the cylindrical shell through a number of circumferentially distributed first radial connecting parts.

[0011] After the cylinder end cap is positioned with the cylinder skin by the positioning flange, the cylinder skin is then connected to the cylinder end cap by several circumferentially distributed second radial connectors.

[0012] Preferably, each of the cylinder end caps is provided with a bearing seat on the main shaft on the side away from the other cylinder end cap, and the bearing seat is connected to the belt conveyor bracket.

[0013] Preferably, one end of the spindle is connected to a rotation drive device for driving the spindle to rotate or a fixing device for restricting the rotation of the spindle.

[0014] Preferably, the rotation drive device is a geared motor.

[0015] Preferably, the magnetic system assembly includes two magnetic yoke disks fixed on the main shaft, and the two magnetic yoke disks are disposed between the two cylindrical end caps and close to the cylindrical end caps respectively;

[0016] Several magnetic base plates are connected to the outer walls of the two magnetic yoke disks;

[0017] It also includes magnetic strips, which can be fixed to the outside of the magnetic base plate, and the magnetic wrap angle of the magnetic system assembly is greater than 0 degrees and less than or equal to 360 degrees.

[0018] Preferably, the magnetic yoke includes two semi-circular arc plates, and shaft holders are fixed on the side walls of the two semi-circular arc plates in the same direction at the inner arc position. After the two shaft holders are connected, they can hold the main shaft tightly.

[0019] Preferably, the magnetic strip is rectangular.

[0020] Preferably, the magnetic stripe includes a plurality of magnetic blocks, which are fixed to the magnetic stripe base plate.

[0021] Preferably, the magnetic stripe can be encapsulated in a non-magnetic material encapsulation box.

[0022] Preferably, it also includes a tail roller, which is connected to the magnetic sorting roller via a conveyor belt;

[0023] The tail roller is configured as a built-in electric roller, or an external electric roller, or a mechanical roller driven by a geared motor.

[0024] The advantages of this utility model are:

[0025] 1. The connection structure between the cylinder skin and the cylinder end cap, as well as the connection structure between the cylinder skin and the positioning flange of this utility model, can realize the flexible disassembly and reassembly of the cylinder skin on the magnetic sorting drum, and can quickly realize the adjustment of the magnetic system with any wrap angle inside the magnetic sorting drum. It can meet the application requirements of various material scenarios by flexibly replacing and matching some components. In addition, compared with the traditional cylinder skin fixed to the cylinder end cap by axial connection, the connection strength between the cylinder skin and the cylinder end cap is also improved.

[0026] 2. In this utility model, the magnetic sorting roller that rotates with the conveyor belt is connected to the main shaft through a bearing, which eliminates the burden on the bearing from the magnetic system assembly and greatly reduces the rotational resistance of the magnetic sorting roller.

[0040] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0041] like Figures 1 to 5 As shown, a multi-scenario quick-installation dry sorting belt conveyor includes a magnetic sorting roller 2, which can separate magnetic and non-magnetic materials. It also includes a tail roller, which is connected to the magnetic sorting roller 2 by a conveyor belt. The tail roller can be a built-in electric roller, an external electric roller, or a mechanical roller driven by a geared motor.

[0042] The magnetic sorting roller 2 includes a main shaft 11, the length of which is greater than the width of the conveyor belt. The main shaft 11 is provided with two cylindrical end caps 12 with a certain distance between them. The cylindrical end caps 12 are rotatably connected to the main shaft 11 by bearings 13. A magnetic system assembly 14 is fixed on the main shaft 11 located between the two cylindrical end caps 12.

[0043] The main shaft 11 is externally fitted with a cylindrical shell 15. A positioning flange 16 is located at each end of the inner side of the cylindrical shell 15. The positioning flange 16 is connected to the cylindrical shell 15 via several circumferentially distributed first radial connecting parts 17, preferably bolts and positioning pins. The positioning flange 16 of this invention serves two purposes: firstly, to ensure the roundness of the cylindrical shell 15 and prevent deformation; and secondly, to facilitate the positioning and installation of the cylindrical shell 15. Traditionally, the positioning flange 16 is directly welded to the cylindrical shell 15. However, this invention, through a detachable structure, allows for easy assembly of the positioning flange 16 with the cylindrical shell while ensuring direct disassembly of the cylindrical shell 15 later, facilitating the adjustment of the internal magnetic system.

[0044] Specifically, after the cylinder end cap 12 is positioned to the cylinder skin 15 via the positioning flange 16, the cylinder skin 15 is then connected to the cylinder end cap 12 via several circumferentially distributed second radial connectors 18. These second radial connectors 18 are preferably bolts and positioning pins. Of course, to ensure the connection strength between the cylinder skin 15 and the cylinder end cap 12, it is preferable to use several axial bolts to further connect the positioning flange 16 to the cylinder end cap 12.

[0045] This invention improves the connection structure between the cylinder skin 15 and the cylinder end cap 12, as well as the connection structure between the cylinder skin 15 and the positioning flange 16. This enables flexible disassembly of the cylinder skin 15 on the magnetic sorting roller 2 and quick adjustment of the magnetic system with arbitrary wrap angle inside the magnetic sorting roller 2. In addition, compared with the traditional method of fixing the cylinder skin 15 to the cylinder end cap 12 through axial connection, the connection strength between the cylinder skin 15 and the cylinder end cap 12 is also improved.

[0046] Furthermore, unlike the traditional structure where the main shaft 11 and the drum 15 rotate relative to each other, the entire magnetic sorting roller 2 is supported by the rotation of the main shaft 11. This not only increases the rotational load on the main shaft 11 due to the increased burden on the magnetic system assembly 14, but also makes adjustment of the magnetic system assembly 14 inconvenient. In this invention, the part of the magnetic sorting roller 2 that rotates with the conveyor belt is connected to the main shaft 11 via a bearing 13, eliminating the burden on the bearing 13 from the magnetic system assembly 14 and significantly reducing the rotational resistance of the magnetic sorting roller 2.

[0047] Each of the main shafts 11 on the side of the cylindrical end cap 12 away from the other cylindrical end cap 12 is provided with a bearing seat 5, and the bearing seat 5 is connected to the belt conveyor bracket 1. One end of the main shaft 11 is connected to a rotation drive device 3 for driving the main shaft 11 to rotate or a fixing device 4 for restricting the rotation of the main shaft 11. The rotation drive device 3 is preferably a geared motor.

[0048] Specifically, by using the fixing device 4 that restricts the rotation of the main shaft 11, the magnetic system can be fixed after the deflection angle is adjusted to a certain angle; while by using the rotation drive device 3 that drives the main shaft 11 to rotate, it can rotate in the same direction or in the opposite direction as the cylinder skin 15, increasing the number of magnetic system tumbling times in the material sorting process, and meeting the sorting requirements of finer materials.

[0049] like Figures 6 to 11 As shown, the magnetic system assembly 14 of this utility model includes two magnetic yoke disks 141 fixed on the main shaft 11. The two magnetic yoke disks 141 are arranged between two cylindrical end caps 12 and close to the cylindrical end caps 12 respectively. Several magnetic base plates 143 are connected to the outer walls of the two magnetic yoke disks 141. The magnetic base plates can be evenly distributed around the circumference or reasonably set according to the magnetic system wrap angle.

[0050] It also includes a magnetic strip 145, which can be fixed on the outside of the magnetic base plate 143, and the magnetic wrap angle of the magnetic system assembly 14 is greater than 0 degrees and less than or equal to 360 degrees.

[0051] Specifically, the magnetic yoke 141 includes two semi-circular arc plates, and shaft holders 142 are fixed on the side walls of the two semi-circular arc plates in the same direction at the inner arc position. After the two shaft holders 142 are connected, they can hold the main shaft 11 tightly.

[0052] The magnetic strip 145 specifically includes several magnetic blocks, which are fixed on the magnetic base plate 143. The magnetic strip 145 can be encapsulated by a non-magnetic encapsulation box 144. By adjusting the encapsulation position of the encapsulation box 144, the magnetic wrap angle can be adjusted to meet the particle size separation requirements of different materials.

[0053] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
