Description

Technical Field

[0001] This utility model relates to an electromagnetic iron separator with explosion-proof function, belonging to the technical field of electromagnetic iron separators. Background Technology

[0002] With the rapid development of my country's economy, the demand and requirements for industries such as coal, thermal power generation, mining, and metallurgy are also increasing. During the production process, non-magnetic materials in the form of lumps or powders are generated. These materials often contain iron pieces or blocks, which may damage the machinery used to process the materials. Therefore, it is necessary to use an iron remover to pre-treat these materials, remove iron impurities, and thus achieve the purpose of iron removal.

[0003] Existing explosion-proof iron separators generally use permanent magnets. However, the magnetic attraction of permanent magnets is limited and cannot meet all working conditions. In addition, during the operation of the iron separator, the conveying direction of the iron separator's transmission belt is set perpendicular to the material transport direction. The transported material is usually quite thick, and the iron separator can only adsorb iron blocks mixed in the surface material, while iron blocks buried inside the material cannot be adsorbed.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing an electromagnetic iron separator with explosion-proof function, which can reduce friction and static electricity generation, thereby achieving an explosion-proof effect; it can also increase the iron removal rate.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] An explosion-proof electromagnetic separator includes a frame, an electromagnetic magnet installed in the middle of the frame, an active roller and a passive roller respectively at both ends of the frame, and an explosion-proof belt wound on the active roller and the passive roller. The explosion-proof belt includes an inner belt and an outer belt arranged at intervals, and supporting ribs are provided at equal intervals between the inner belt and the outer belt.

[0008] The bottom of the electromagnetic magnet is provided with multiple transmission rollers arranged along the transmission direction of the explosion-proof belt, and the two ends of the transmission rollers are rotatably mounted on the bracket.

[0009] Furthermore, the lower end of the explosion-proof belt is provided with multiple front connecting arms arranged side by side, and a lever is installed at the lower end of each front connecting arm.

[0010] Furthermore, the front connecting arm includes a horizontal arm, the lower end of which is provided with a first hinge ring and a second hinge ring spaced apart along its axial direction, and the upper end of the lever is hinged to the second hinge ring of the front connecting arm.

[0011] A third hinge ring is provided at the middle position of the lever, and a tension spring is hung on the third hinge ring and the first hinge ring.

[0012] Furthermore, the rear end of the front connecting arm is provided with a mounting sleeve, and the mounting sleeves of multiple front connecting arms are fitted onto the rear axle.

[0013] Furthermore, a rear connecting arm is provided between two adjacent front connecting arms, and a lever is hinged to the lower end of the rear connecting arm.

[0014] Furthermore, the lower end of the rear connecting arm is provided with a first hinge ring and a second hinge ring spaced apart along its axial direction, and the upper end of the lever is hinged to the second hinge ring of the rear connecting arm; a third hinge ring is provided at the middle position of the lever, and a tension spring is hung on the third hinge ring and the first hinge ring.

[0015] Furthermore, the front end of the rear connecting arm is provided with a mounting sleeve, which is installed on the rear axle. The rear connecting arm and the front connecting arm are respectively located on both sides of the rear axle.

[0016] Furthermore, the front connecting arm also includes a vertical arm that is vertically connected to its horizontal arm. The top of the vertical arm is provided with a mounting sleeve, which is fitted onto the front axle. Both ends of the front axle are fixed to the frame.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] The explosion-proof belt consists of an inner belt and an outer belt spaced apart. When an iron block is attracted to the explosion-proof belt, it can reduce the impact force of the iron block on the electromagnetic magnet, thereby avoiding the generation of static electricity. On the other hand, it can reduce the transfer of static electricity to the electromagnetic magnet. The transmission roller and the explosion-proof belt are in rolling contact. The rolling friction is less than the sliding friction, which reduces the generation of static electricity and thus achieves the explosion-proof effect.

[0019] The front connecting arm and the rear connecting arm are arranged one after the other. The lever at the lower end of the front connecting arm first moves the material, pushing some of the iron blocks in the material to the surface where they are adsorbed. Then the lever at the lower end of the rear connecting arm moves the material again, further pushing some of the iron blocks in the material to the surface where they are adsorbed, resulting in a higher iron removal rate.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, this utility model provides an electromagnetic iron separator with explosion-proof function, including a frame 1, an electromagnetic magnet 5 installed in the middle of the frame 1, an active roller 2 and a passive roller 3 respectively provided at both ends of the frame 1, and an explosion-proof belt 4 wound on the active roller 2 and the passive roller 3. The explosion-proof belt 4 includes an inner belt 401 and an outer belt 402 arranged at intervals, and supporting ribs 403 are provided at equal intervals between the inner belt 401 and the outer belt 402.

[0029] The bottom of the electromagnetic magnet 5 is provided with multiple transmission rollers 7 arranged along the transmission direction of the explosion-proof belt 4, and the two ends of the transmission rollers 7 are rotatably mounted on the bracket 6.

[0030] The explosion-proof belt 4 consists of an inner belt 401 and an outer belt 402 spaced apart. When an iron block is attracted to the explosion-proof belt 4, it can reduce the impact force of the iron block on the electromagnetic magnet 5, thereby avoiding the generation of static electricity. On the other hand, it can reduce the transfer of static electricity to the electromagnetic magnet 5. The transmission roller 7 and the explosion-proof belt 4 are in rolling contact. The rolling friction is less than the sliding friction, which reduces the generation of static electricity and thus achieves the explosion-proof effect.

[0031] like Figure 4 The lower end of the explosion-proof belt 4 is provided with multiple front connecting arms 10 arranged side by side, and each front connecting arm 10 is equipped with a lever 13 at its lower end.

[0032] The front connecting arm 10 includes a horizontal arm. The lower end of the horizontal arm is provided with a first hinge ring 11 and a second hinge ring 12 spaced apart along its axial direction. The upper end of the lever 13 is hinged to the second hinge ring 12 of the front connecting arm 10. A third hinge ring 14 is provided at the middle position of the lever 13. A tension spring (not shown in the figure) is hung on the third hinge ring 14 and the first hinge ring 11.

[0033] The rear end of the front connecting arm 10 is provided with a mounting sleeve 16, and the mounting sleeves 16 of the multiple front connecting arms 10 are fitted onto the rear axle 8.

[0034] A rear connecting arm 15 is provided between two adjacent front connecting arms 10, and a lever 13 is hinged to the lower end of the rear connecting arm 15.

[0035] The lower end of the rear connecting arm 15 is provided with a first hinge ring 11 and a second hinge ring 12 spaced apart along its axial direction. The upper end of the lever 13 is hinged to the second hinge ring 12 of the rear connecting arm 15. A third hinge ring 14 is provided at the middle position of the lever 13. A tension spring (not shown in the figure) is hung on the third hinge ring 14 and the first hinge ring 11.

[0036] The rear connecting arm 15 has a mounting sleeve 16 at its front end. The mounting sleeve 16 of the rear connecting arm 15 is mounted on the rear axle 8. The rear connecting arm 15 and the front connecting arm 10 are located on opposite sides of the rear axle 8.

[0037] Since the front connecting arm 10 and the rear connecting arm 15 are arranged one behind the other, the lever 13 at the lower end of the front connecting arm 10 first moves the material, pushing some of the iron blocks in the material to the surface where they are adsorbed. Then, the lever 13 at the lower end of the rear connecting arm 15 moves the material again, further pushing some of the iron blocks in the material to the surface where they are adsorbed, resulting in a higher iron removal rate.

[0038] The front connecting arm 10 also includes a vertical arm that is vertically connected to its horizontal arm. The top of the vertical arm is provided with a mounting sleeve 16, which is fitted onto the front axle 9. Both ends of the front axle 9 are fixed to the frame 1.
