Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic iron removal devices, and particularly relates to a quick-release permanent magnet iron removal device applied to a belt conveyor. Background Art

[0002] During the transportation of a belt conveyor, since iron parts are often mixed in the materials, it often causes scratches and cracks on the conveyor belt and damage to equipment such as crushers in the next process, bringing adverse effects to the production line. The most common solution at present is to hang an iron remover above the belt conveyor to remove ferromagnetic impurities mixed on the conveyor belt and prevent iron devices from damaging the equipment on the production line.

[0003] At present, the iron removal devices on the market are mainly divided into two types: ordinary iron removers and self-unloading iron removers. In the process of implementing the present utility model, it is found that at least the following problems in the prior art have not been solved:

[0004] 1. Ordinary iron removers are generally suspended above the conveyor belt of the belt conveyor by iron chains or steel ropes. When dealing with the iron parts adsorbed on them, the permanent magnet iron remover needs to be unloaded by an electric hoist or the workers need to climb onto the upper belt surface of the belt conveyor for processing operations. No matter which processing method is used, it can only be carried out when the belt conveyor is stopped, which greatly reduces the production efficiency of the enterprise.

[0005] 2. Most of the existing self-unloading iron removers are equipped with a driving mechanism of a transmission belt or chain drive outside the permanent magnet iron remover, and the iron parts that can be adsorbed are thrown out along with the movement of the belt or chain during the production process. However, this type of iron removal device has a relatively large volume due to the installation of a motor and a speed reducer, requires a large installation space, and the procurement cost is also relatively high. At the same time, the working form of the device throwing out the iron parts by pulling hard is also likely to cause damage to the unloading iron parts belt or the motor, resulting in an increase in maintenance costs and an increase in the work intensity of maintenance personnel. Summary of the Invention

[0006] The purpose of the present utility model is to provide a quick-release permanent magnet iron removal device dedicated to a belt conveyor in view of the above-mentioned deficiencies of the prior art. This device can clean the iron parts on the iron remover without stopping the belt conveyor, thereby improving the work efficiency.

[0007] The purpose of the present utility model is achieved as follows.

[0008] A quick-release permanent magnet iron remover of the utility model is characterized by comprising a device frame, a buffer, an iron remover mounting frame, an iron remover body, a lower swing arm, an upper swing arm and a baffle plate mechanism. The device frame is a portal structure composed of a rectangular upper frame A and four support frames. The bottoms of the four support frames are fixedly installed on the intermediate frame of the belt conveyor through bolts. There are four buffers, which are symmetrically arranged at the left ends of the long sides and the middle sides of the right sides of the long sides of the rectangular upper frame respectively. The iron remover mounting frame is a rectangular frame B shorter than the rectangular upper frame A. Buffer baffles A are respectively arranged on both sides of the right part of the long side of the rectangular frame B. One end of the lower swing arm is symmetrically hinged to both sides of the lower part of the left support frame through a hinge shaft A, and the other end is respectively hinged to the left ends of the long side of the rectangular frame B through a hinge shaft B. One end of the upper swing arm is symmetrically hinged to the inner sides of the left side of the rectangular upper frame A through a hinge shaft C, and the other end is respectively hinged to both sides of the right side of the long side of the rectangular frame B through a hinge shaft D. A buffer baffle B is also arranged on the left side surface of the upper swing arm, so that the iron remover mounting frame is movably connected with the device frame. The iron remover body is arranged in the middle of the belt conveyor and is fixedly installed on the rectangular frame B through bolts. One end of the baffle plate is a baffle plate with iron strips, which is arranged at the bottom of the rectangular frame B. One end is fixed on the short side of the rectangular frame B, and the other end is adsorbed on the iron remover body.

[0009] As a further description of the above technical solution: The baffle plate is made of a plurality of nylon plates with iron strips at one end flexibly connected. One end of the baffle plate is fixedly connected to the right end of the rectangular frame B, and the end with the iron strips is adsorbed on the iron remover body, so that it completely covers the bottom of the iron remover body.

[0010] As a further description of the above technical solution: A handle is also arranged at the left end of the iron remover mounting frame.

[0011] The advantages of the utility model are:

[0012] By adopting the above technical solution, the device can be directly installed on the intermediate frame of the belt conveyor in terms of structural form, without installing the iron remover through other forms such as steel beams. Moreover, the device has a small volume, greatly alleviating the problem of insufficient space in the corridors of some belt conveyors. At the same time, the whole device does not require a driving device and has a low cost. In terms of the operation process, workers can move the iron remover from the upper part of the belt conveyor to one side by pulling, and the cleaning operation can be carried out without stopping the belt conveyor, greatly improving the work efficiency.

[0016] The present utility model will be described in detail below in conjunction with embodiments.

[0017] To make the purpose, technical solution and advantages of the present utility model clearer, the following further details the embodiments of the present utility model in conjunction with specific embodiments and with reference to the accompanying drawings:

[0018] As From Figure 1 to Figure 2 shown, a quick-release permanent magnet iron remover device of the present utility model is characterized in that

[0019] It includes a device frame, a buffer 2, an iron remover mounting frame, an iron remover main body 4, a lower swing arm 5, an upper swing arm 6 and a baffle plate mechanism 7. The device frame is a portal structure composed of a rectangular upper frame A11 and four support frames 12. The bottoms of the four support frames 12 are fixedly installed on the intermediate frame 9 of the belt conveyor by bolts; There are four buffers, which are symmetrically arranged at the left ends of the long sides of the rectangular upper frame A and the middle sides of the right sides of the long sides respectively; The iron remover mounting frame is a rectangular frame B3 shorter than the upper frame A of the rectangular frame. Buffer baffle plates A31 are respectively arranged on both sides of the right part of the long side of the rectangular frame B; One end of the lower swing arm 5 is symmetrically hinged on both sides of the lower part of the left support frame 12 through a hinge shaft A51, and the other end is respectively hinged to the left ends of the long sides of the rectangular frame B3 through a hinge shaft B52. One end of the upper swing arm 6 is symmetrically hinged on the inner sides of the left side of the rectangular upper frame A11 through a hinge shaft C62, and the other end is respectively hinged to the right side parts of the long sides of the rectangular frame B3 through a hinge shaft D63.
