Description

TECHNICAL FIELD

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

[0002] In the transportation of a belt conveyor, iron pieces are often mixed in the materials, which often causes scratches and cracks of the conveying belt and damages to devices such as a crusher in the next process, thereby bringing adverse effects to the production line. The most widely used solution at present is to hang an iron removal device above the belt conveyor to remove ferromagnetic impurities mixed in the conveying belt and prevent the damage of iron pieces to the devices on the production line.

[0003] At present, the iron removal devices on the market mainly include ordinary iron removal devices and self-discharging iron removal devices. In the process of implementing the application, it is found that the following problems in the prior art have not been solved: 1. The ordinary iron removal device is generally suspended on the upper part of the conveying belt of the belt conveyor through iron chains or steel ropes. When the iron pieces adsorbed on the device are treated, the permanent magnetic iron removal device needs to be unloaded through an electric hoist or workers need to climb onto the belt surface of the belt conveyor to perform the treatment operation. No matter which treatment method is used, the treatment can only be performed when the belt conveyor is stopped, which greatly reduces the production efficiency of the enterprise. 2. The existing self-discharging iron removal device is mostly provided with a driving mechanism of a transmission belt or a chain transmission outside the permanent magnetic iron removal device. In the production process, the iron pieces adsorbed on the device are thrown out along with the movement of the belt or the chain. However, the iron removal device of this form is provided with a motor and a speed reducer, so the device has a large size and needs a large installation space. The procurement cost is also relatively high. At the same time, the working form of throwing out the iron pieces by the device is hard and rough, which is easy to cause the belt to be pulled and injured or the motor to be damaged, thereby increasing the maintenance cost and the working intensity of the maintenance personnel. SUMMARY

[0004] The application aims at the deficiencies of the prior art and provides a quick-release permanent magnetic iron removal device specially used on a belt conveyor. The device can clean the iron pieces on the iron removal device without stopping the belt conveyor, thereby improving the working efficiency.

[0005] The application is realized in this way.

[0006] This invention discloses a quick-release permanent magnet iron removal device, characterized in that it comprises a device frame, buffers, 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 consists of a rectangular upper frame A and four support frames forming a portal structure. The bottoms of the four support frames are bolted to the intermediate frame of a belt conveyor. Four buffers are symmetrically arranged on the left ends and the right middle side of the long side of the rectangular upper frame. The iron remover mounting frame is a rectangular frame B shorter than the rectangular upper frame A, with buffer baffle plates A on both sides of the right side of the long side of the rectangular frame B. One end of the lower swing arm is symmetrically hinged to the left side via hinge pin A. The lower two sides of the support frame are hinged to the left ends of the long side of the rectangular frame B via hinge pin B. One end of the upper swing arm is symmetrically hinged to the two inner sides of the left side of the upper rectangular frame A via hinge pin C, and the other end is hinged to the right sides of the long side of the rectangular frame B via hinge pin D. A buffer baffle B is also provided on the left side of the upper swing arm, so that the iron separator mounting frame and the device frame form a movable connection. The iron separator body is set in the middle of the belt conveyor and fixed to the rectangular frame B with bolts. One end of the baffle plate is a baffle plate with iron strips, which is set at the bottom of the rectangular frame B. One end is fixed to the short side of the rectangular frame B, and the other end is attached to the iron separator body.

[0007] As a further description of the above technical solution: the baffle plate is made of multiple nylon plates with iron strips at one end, which are flexibly connected together. 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 separator body, so that it completely covers the bottom of the iron separator body.

[0008] As a further description of the above technical solution: a handle is also provided at the left end of the iron separator mounting bracket.

[0009] The advantages of this invention are: By adopting the above technical solution, the device can be directly installed on the intermediate frame of the belt conveyor, eliminating the need for steel beams or other methods to install the magnetic separator. Furthermore, the device is relatively small in size, greatly alleviating the problem of insufficient space in some belt conveyor corridors. Additionally, the entire device requires no drive unit, resulting in low cost. In terms of operation, workers can move the magnetic separator from the top of the belt conveyor to one side by pulling it, allowing for cleaning operations without stopping the conveyor, significantly improving work efficiency.

[0010] Fig. 1 This is an isometric view of the iron removal operation of the device of the present invention; Fig. 2 This is an isometric view of the unloading condition of the device of the present invention; Fig. 3This is a schematic diagram of the working state of the device of the present invention during unloading and cleaning of iron parts. Detailed Implementation

[0011] The present invention will now be described in detail with reference to the embodiments.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings: like Figs. 1-2 As shown, the present invention provides a quick-release permanent magnet iron removal device, characterized in that... The device includes a frame, a buffer 2, a magnetic separator mounting bracket, a magnetic separator body 4, a lower swing arm 5, an upper swing arm 6, and a baffle plate mechanism 7. The frame consists of a rectangular upper frame A11 and four support frames 12 forming a portal structure. The bottoms of the four support frames 12 are bolted to the intermediate frame 9 of the belt conveyor. Four buffers are symmetrically arranged on the left ends and the right middle side of the long side of the rectangular upper frame A. The magnetic separator mounting bracket is a rectangular frame B3 shorter than the rectangular upper frame A, with buffer baffle plates A31 on both sides of the right side of the long side of the rectangular frame B. One end of the lower swing arm 5 is symmetrically hinged to the lower sides of the left support frame 12 via hinge pins A51, and the other end... The upper swing arm 6 is hinged to the left ends of the long side of the rectangular frame B3 via hinge pin B52. One end of the upper swing arm 6 is symmetrically hinged to the two inner sides of the left side of the rectangular upper frame A11 via hinge pin C62, and the other end is hinged to the right sides of the long side of the rectangular frame B3 via hinge pin D63. A buffer baffle B61 is also provided on the left side of the upper swing arm 6, so that the iron separator mounting frame and the device frame form a movable connection. The iron separator body 4 is set in the middle of the belt conveyor and is fixed to the rectangular frame B3 by bolts. The iron baffle 7 is an iron baffle with iron strips 71 at one end, set at the bottom of the rectangular frame B3, fixed at one end on the short side of the rectangular frame B, and the other end is attached to the iron separator body 4.

[0013] The present invention has a buffer baffle A31 fixed at the right end of the iron separator mounting frame. When the device is pulled from the unloading condition to the iron removal condition, the buffer baffle A31 on the iron separator mounting frame hits the buffer, reducing the impact load on the device and the operator.

[0014] The present invention provides a buffer baffle B61 on the upper swing arm 6. When the upper swing arm 6 is pulled from the iron removal condition to the unloading condition, the buffer baffle B61 on the upper swing arm 6 impacts the buffer 2, thereby reducing the impact load on the device and the operator.

[0015] In one embodiment of the present invention, the baffle plate 7 is made of multiple nylon plates 7 flexibly connected with iron strips 71 at one end. One end of the baffle plate 7 is fixedly connected to the right end of the rectangular frame B3, and the end with the iron strips is adsorbed on the iron separator body 4 so that it completely covers the bottom of the iron separator body.

[0016] The present invention also provides a handle 8 at the left end of the iron remover mounting bracket.

[0017] During operation, workers can move the iron remover from the top of the belt conveyor to one side by pulling handle 8, which allows for cleaning without stopping the belt conveyor, greatly improving work efficiency.

[0018] During unloading, the iron strip end of the baffle plate 7 can be pulled off the iron separator body 4 manually, so that the iron parts on the baffle plate 7 can fall into the material box.

[0019] First, it should be noted that the directional terms such as "up," "down," "left," "right," and "side" described in this application are only for the position of the quick-release permanent magnet iron removal device of this invention as shown in the figure. This is only to more clearly indicate the relative positional relationship between the components. When the placement of the dry magnetic separator changes, the directions such as "up," "down," "left," "right," "top," and "bottom" will also change accordingly, but this is still within the protection scope of this application.

[0020] The above description describes the specific structural form of the present invention. The present invention is not limited to the above embodiments. For those skilled in the art, equivalent changes to the specific structure and component substitutions based on the present invention are all within the protection scope of the present invention.
