Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a magnetic separator with a dustproof structure. Background Technology

[0002] Magnetic separators are widely used in industries such as mining and metallurgy to separate magnetic materials using magnetic force. During the magnetic separation process, especially in dry magnetic separation, a large amount of dust is generated during feeding, tumbling, and separation. This dust not only seriously pollutes the working environment and endangers the health of operators, but also leads to accelerated wear of key equipment components (such as bearings and transmission systems), reducing the service life of the equipment.

[0003] Most existing magnetic separators only use simple sealing covers or single dust removal equipment, which have limited dust prevention effect, cannot effectively control dust overflow, and are inconvenient to clean and maintain. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a magnetic separator with a dustproof structure. By incorporating a negative pressure dust collection structure, a downward airflow barrier is formed at the source of dust generation, directly drawing most of the rising dust into the dust collection hood.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1.

[0019] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0021] like Figure 1 As shown, the embodiment of this utility model includes a housing 1, a magnetic separator 2, a drive motor, a negative pressure dust collection structure, and an air intake structure. The housing 1 is a sealed structure, welded from steel plates, forming a sorting chamber inside. The magnetic separator 2 is fixedly mounted on the frame via bearing seats, and the drive motor is connected to the drive shaft of the magnetic separator 2 via a transmission belt, driving the magnetic separator 2 to rotate. The surface of the magnetic separator 2 is provided with magnetic and non-magnetic areas, and corresponding magnetic and non-magnetic material outlets are respectively provided on the housing 1. The negative pressure dust collection structure and the air intake structure are symmetrically arranged at the left and right ends of the housing 1, working together to form an airflow barrier, effectively capturing and removing dust.

[0022] In this embodiment, the negative pressure dust collection structure includes a dust collection hood 3, a connecting pipe, a first dust collection structure, and a second dust collection structure. The dust collection hood 3 is a long strip structure arranged along the axial direction of the magnetic separator 2, made of stainless steel plate. Its bottom edge maintains a gap of 2-5mm with the surface of the magnetic separator 2 to avoid contact wear while ensuring dust collection effect. The dust collection hood 3 is fixedly installed on the top of the equipment housing 1 by a bracket, covering the entire working length of the magnetic separator 2.

[0023] In this embodiment, the first dust collection structure is located on the upper left side of the equipment housing 1 and includes a first fan box 4 and a first dust collection box 5. The first dust collection box 5 is fixedly installed on the left end wall of the equipment housing 1 by bolts, and its interior communicates with the inner cavity of the equipment housing 1 through an opening. The first dust collection box 5 contains a first filter box, which includes a first left filter box 6 and a first right filter box 7 connected in parallel, both composed of metal mesh and high-efficiency filter cotton, and are removable for easy cleaning. The first fan box 4 is connected to the outlet end of the first dust collection box 5 by a flange. The first fan box 4 contains a first dust collection fan 8 (e.g., a centrifugal fan), and a first air intake filter (using a HEPA filter) is embedded at the air inlet of the first fan box 4. The air intake end of the first dust collection fan 8 is connected to the first dust collection box 5 through the first air intake filter. The first dust collection structure is connected to the left end of the dust collection hood 3 through a connecting pipe (using a flexible corrugated pipe), and the connecting pipe is fixed by clamps.

[0024] In this embodiment, the second dust collection structure is located on the upper right side of the device housing 1, and its structure is mirror-symmetrical to the first dust collection structure. The second dust collection structure includes a second fan housing 9 and a second dust collection box 10. The second dust collection box 10 contains a second filter box, including a second left filter box 11 and a second right filter box 12. A second dust collection fan 13 is installed inside the second fan housing 9, and a second air intake filter is installed at the air inlet of the second fan housing 9. The air intake end of the second dust collection fan 13 is connected to the second dust collection box 10 through the second air intake filter. The second dust collection structure is connected to the right end of the dust collection hood 3 through another connecting pipe.

[0025] In this embodiment, the first and second dust-collecting structures work simultaneously, forming a negative pressure zone below the dust-collecting hood 3. This draws the dust generated by the magnetic separator 2 during operation into the dust-collecting hood, and then into the dust collection box for filtration and collection through the connecting pipe.

[0026] In this embodiment, the air intake structure includes a first air intake structure and a second air intake structure, which are respectively disposed on the lower left and lower right sides of the equipment housing 1, and are used to inject clean air into the equipment housing 1 to form a positive airflow to suppress dust escape.

[0027] In this embodiment, the first air intake structure includes a first air intake box 14, a first air intake pipe 15, a first air pump structure, and a first nozzle structure. The first air intake box 14 is fixedly installed on the lower left side of the equipment housing 1 by welding, and a primary air filter is provided inside it. The first air intake pipe 15 (using PVC rigid pipe) is connected to the outlet of the first air intake box 14, and the air intake end of the first air pump structure is connected to the first air intake box 14 through the first air intake pipe 15. The first air pump structure includes a first air pump 16, a second air pump 17, a third air pump 18, and a fourth air pump 19 (all oil-free silent air pumps) arranged in parallel. A first mounting base 20 is welded to the left end of the equipment housing 1, and a first mounting column 21 (cylindrical steel column) is fixed to the top of the first mounting base 20 by bolts. The first air pump 16, the second air pump 17, the third air pump 18, and the fourth air pump 19 are fixed to the first mounting column 21 from top to bottom by brackets. The first nozzle structure includes a first nozzle 22, a second nozzle 23, a third nozzle 24, and a fourth nozzle 25 (all fan-shaped nozzles) arranged in parallel. These nozzles are connected to the outlets of the first air pump 16, the second air pump 17, the third air pump 18, and the fourth air pump 19 via air supply pipes (using pressure-resistant flexible hoses). The nozzles face the internal separation chamber of the equipment housing 1, and the spray direction is consistent with the tangential direction of the surface of the magnetic separator drum 2.

[0028] In this embodiment, the second air intake structure includes a second air intake box 26, a second air intake pipe 27, a second air pump structure, and a second nozzle structure. The second air intake box 26 is installed on the lower right side of the equipment housing 1, and the second air intake pipe 27 is connected to the outlet of the second air intake box 26. The second air pump structure includes a fifth air pump 28, a sixth air pump 29, a seventh air pump 30, and an eighth air pump 31 arranged in parallel. A second mounting base 32 is provided at the right end of the equipment housing 1, and a second mounting post 33 is fixed to the top of the second mounting base 32. The fifth air pump 28 to the eighth air pump 31 are installed on the second mounting post 23 from top to bottom. The second nozzle structure includes a fifth nozzle 34, a sixth nozzle 35, a seventh nozzle 36, and an eighth nozzle 37, which are respectively connected to the outlet of the corresponding air pump through air supply pipes. The arrangement of the second air intake structure is symmetrical with that of the first air intake structure to ensure uniform airflow coverage.

[0029] In this embodiment, the working principle is explained as follows: When the magnetic separator is working, the drive motor drives the magnetic separator drum 2 to rotate via a transmission belt. The material to be separated is fed into the feed port at the top of the equipment housing 1. Under the magnetic action of the magnetic separator drum 2, magnetic materials are attracted to the surface of the drum and carried by the rotating belt to the magnetic material discharge port and fall down. Non-magnetic materials are directly discharged from the non-magnetic material discharge port. During this process, the friction and falling of the material will generate a large amount of dust.

[0030] In this embodiment, the dust prevention process is as follows: Negative pressure dust collection: The first and second dust collection structures are activated simultaneously, and the first and second dust collection fans form a negative pressure zone below the dust collection hood 3. Dust is drawn into the dust collection hood 3 under the action of airflow and enters the first dust collection box 5 and the second dust collection box 10 through the connecting pipe. When the dust passes through the first and second filter boxes, it is captured by the filter media, and the clean air is discharged outside the equipment by the fan. The elongated design and gap arrangement of the dust collection hood ensure complete coverage of the entire surface of the magnetic separator roller 2.

[0031] In this embodiment, dust suppression via air intake: the first and second air intake structures operate synchronously. The first air pump 16 to the eighth air pump 31 draw in filtered clean air from the first air intake box 14 and the second air intake box 26, and then spray it into the equipment housing 1 at a certain pressure through nozzles. The sprayed airflow forms a positive airflow barrier within the sorting chamber, working in conjunction with the negative pressure suction airflow to prevent dust from escaping from the discharge port and equipment gaps. The parallel arrangement of multiple air pumps and nozzles ensures uniform and adjustable airflow, adapting to different working conditions.

[0032] In this embodiment, synergistic dust control is achieved through negative pressure suction and air injection, creating a dynamic airflow balance that effectively controls dust diffusion. The filter box in the suction structure can be cleaned or replaced periodically, making maintenance convenient; the air pump and nozzle in the air intake structure are centrally arranged via mounting columns, resulting in a compact structure and space-saving design.

[0033] This embodiment achieves efficient dust prevention for the magnetic separator through a symmetrically designed dust collection and air intake structure, significantly improving the working environment. It also features a stable structure that is easy to maintain.
