Description

Technical Field

[0001] This utility model belongs to the technical field of magnetic iron removal devices, specifically relating to a self-unloading electromagnetic iron removal device for belt conveyors. Background Technology

[0002] In belt conveyor transportation, iron parts are often mixed in with the materials, which often causes scratches and cracks on the conveyor belt and damages equipment such as crushers in the next process, thus adversely affecting the production line. The most common solution at present is to hang an iron remover above the belt conveyor to remove ferromagnetic debris mixed on the conveyor belt and prevent iron parts from damaging the equipment on the production line.

[0003] Currently, the main types of iron removal devices on the market are ordinary iron separators and self-unloading iron separators. The following problems remain unresolved with existing technologies:

[0004] 1. Ordinary magnetic separators are typically suspended from the upper part of a belt conveyor using chains, hooks, hand-operated hoists, or steel ropes. This installation method requires either removing the permanent magnet separator using a hand-operated hoist or having workers climb onto the belt conveyor to handle the iron adhering to it. Regardless of the method, this process can only be performed when the belt conveyor is stopped, significantly impacting and reducing enterprise production efficiency.

[0005] 2. Some companies use a hoisting beam with an electric hoist to suspend ordinary iron removers on the upper part of the belt conveyor. Although this method can solve the problems of machine downtime and workers climbing onto the belt conveyor to carry out processing operations, it has high site requirements and large investment.

[0006] 3. Existing self-unloading iron separators, such as the Chinese patent CN216573574U, involve adding a drive mechanism via a transmission belt or chain plate to the outside of the permanent magnet iron separator. During production, the iron parts that can be attracted are thrown out by the movement of the belt or chain. However, this type of iron separator is relatively large because it has a motor and a reducer. It requires a corresponding steel structure platform, such as a crossbeam, to be installed on the belt conveyor, which occupies a lot of space and has relatively high installation costs and requirements for the installation site. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a self-unloading electromagnetic iron removal device, which aims to improve the problems of complex structure and large space occupation in the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a self-unloading electromagnetic iron removal device, characterized in that: it includes two device mounting frames, a swing frame, a connecting shaft, a drive mechanism, and an electromagnetic iron remover. The two device mounting frames are respectively fixed to the bottom of the channel steel of the intermediate frame of the belt conveyor by bolts. A telescopic electric cylinder mounting groove is opened on the device mounting frame. A swing frame mounting hole is opened at the end of the device mounting frame. Sliding grooves are opened on both sides of the device mounting frame.

[0009] The swing frame is composed of two L-shaped diagonally welded angle steels and three connecting angle steels connecting the two L-shaped diagonally welded angle steels. Each L-shaped diagonally welded angle steel is composed of a horizontal support angle steel and a longitudinal support angle steel perpendicularly connected to the horizontal support angle steel. Axle lug I is provided on the upper part of the two horizontal support angle steels respectively, and axle lug II is provided on the upper part of the electromagnetic separator. The connecting shaft passes through axle lug I and axle lug II to suspend the electromagnetic separator between the two horizontal support angle steels.

[0010] The drive mechanism includes a telescopic electric cylinder and a movable rod. The telescopic electric cylinder is fixed in the mounting groove of the device mounting frame by bolts. The lower part of the longitudinal support angle steel has shaft holes A and B respectively. The pin passes through the shaft hole A in the lower part of the longitudinal support angle steel and the swing frame mounting hole of the device mounting frame to hinge the longitudinal support plate and the device mounting frame. One end of the movable rod is hinged to the shaft hole B by a pin, and the other end is hinged to the telescopic end connecting lug of the telescopic electric cylinder by a pin, and slides in the slide groove of the mounting frame.

[0011] As a further description of the above technical solution: a reinforcing diagonal brace is provided at the connection between the horizontal support angle steel and the longitudinal support angle steel.

[0012] The advantages of this utility model are:

[0013] Compared with existing technologies, this utility model has a simple structure, occupies little space, and is suitable for monitoring vulnerable points of liners in various non-conductive material production and transportation equipment. It can remove iron by controlling the on / off state of the telescopic electric cylinder and electromagnetic separator through a controller program, or by moving the electromagnetic separator to one side of the belt conveyor so that the attached iron pieces automatically fall into the lower hopper. The cleaning process requires neither stopping the belt conveyor nor manual operation, greatly improving the efficiency and safety of the production line. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and accompanying drawings.

[0019] like Figures 1 to 4 The self-unloading electromagnetic iron removal device shown is characterized by comprising two device mounting frames 1, a swing frame, a connecting shaft, a drive mechanism, and an electromagnetic iron remover 4. The two device mounting frames 1 are respectively fixed to the bottom of the channel steel 3 of the intermediate frame of the belt conveyor by bolts. The device mounting frames 1 are provided with telescopic electric cylinder mounting slots, the ends of the device mounting frames 1 are respectively provided with swing frame mounting holes 11, and the sides of the device mounting frames 1 are provided with sliding grooves 12.

[0020] The swing frame is composed of two L-shaped diagonally welded angle steels and three connecting angle steels connecting the two L-shaped diagonally welded angle steels. Each L-shaped diagonally welded angle steel is composed of a horizontal support angle steel 211 and a longitudinal support angle steel 212 perpendicularly connected to the horizontal support angle steel 211. The upper part of the two horizontal support angle steels 211 is provided with lug I 31, and the upper part of the electromagnetic separator 4 is provided with lug II 41. The connecting shaft 5 passes through lug I 31 and lug II 41 to suspend the electromagnetic separator 4 between the two horizontal support angle steels 211.

[0021] The drive mechanism includes a telescopic electric cylinder 8 and a movable rod 7. The telescopic electric cylinder 8 is fixed in the mounting groove of the device mounting frame 1 by bolts. The lower part of the longitudinal support angle steel 212 has shaft holes A213 and B214 respectively. The pin passes through the shaft hole A213 in the lower part of the longitudinal support angle steel and the swing frame mounting hole 11 of the device mounting frame to hinge the longitudinal support plate 21 and the device mounting frame 1. One end of the movable rod 7 is hinged to the shaft hole B214 by a pin, and the other end is hinged to the telescopic end connecting lug of the telescopic electric cylinder 8 by a pin, and slides in the slide groove 12 of the mounting frame.

[0022] As an example, this invention provides a reinforcing diagonal brace 10 at the connection between the horizontal support angle steel and the longitudinal support angle steel. This effectively improves the support strength of the swing frame.

[0023] The swing frame of this invention adopts a double-support structure, which not only ensures uniform force distribution and swing flexibility of the electromagnetic separator on the swing frame, but also increases the strength of the swing frame and extends its service life. Furthermore, the device mounting frame 1, swing frame, movable rod 7, and telescopic electric cylinder 8 form a four-bar linkage. When iron parts need to be cleaned, the telescopic electric cylinder and electromagnetic separator can be energized via the controller program, placing the electromagnetic separator 4 above the conveyor belt 6. After the iron removal work is completed, the telescopic electric cylinder is extended or retracted via the controller program, causing the longitudinal support angle steel 212 of the swing frame to form a parallel four-bar linkage with the device mounting frame 1. After the electromagnetic separator moves to one side of the belt conveyor, the electromagnetic separator is de-energized, and the iron parts attached to the electromagnetic separator automatically fall into the lower material box 9. The entire cleaning process requires neither stopping the belt conveyor nor manual operation, greatly improving the efficiency and safety of the production line.
