[0046] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0047] like Figure 1 , Figure 2 and Figure 3As shown, this utility model embodiment provides a dust removal device for a magnetic separator, including: a dust removal box 1, a dust receiving box 3, a dust removal pipe 4, and a sorting pipe 5. The interior of the dust removal box 1 is divided into a receiving area 11 and a dust removal area 12 by an inclined filter screen 2. An inlet 13 and an outlet 14 are provided on the side wall of the receiving area 11. The inlet 13 is located at the upward-inclined end of the filter screen 2, and the outlet 14 is located at the downward-inclined end of the filter screen 2. A dust removal port 15 is provided at the bottom of the dust removal area 12. The dust receiving box 3 is detachably installed at the dust outlet. One end of the dust removal pipe 4 is connected to the dust removal area 12. One end of the sorting pipe 5 is a dust removal end 51, and the other end is a discharge end 52. The dust removal end 51 is connected to external dust removal equipment, and the dust removal pipe 4 is connected between the dust removal end 51 and the discharge end 52. When the sorting pipe 5 is connected to the dust removal pipe 4, the discharge end 52 faces the ground.
[0048] The material discharged from the magnetic separator first enters the receiving area 11 inside the dust collection box 1, and then is screened by the inclined filter screen 2. Because the sorting pipe 5 is connected to an external dust collection device, a certain negative pressure is created in the dust collection area 12. Dust, debris, and impurities enter the dust collection area 12 due to this negative pressure. Dust, debris, and impurities are then drawn into the dust collection pipe 4 under the negative pressure, and then pass through the dust collection end 51 of the sorting pipe 5 into the external dust collection device. Debris is discharged through the discharge end 52 of the sorting pipe 5, which is connected to the dust collection pipe 4, due to gravity.
[0049] When there is a large amount of dust, debris, and impurities entering the dust removal zone 12, and the external dust removal equipment cannot completely remove them, some of the dust, debris, and impurities will fall into the dust collection box 3, and then be cleaned manually to avoid the accumulation of dust, debris, and impurities affecting the subsequent use of the dust removal device.
[0050] In one embodiment, such as Figure 1 and Figure 2 As shown, in order to further reduce the risk of dust spillage, the dust removal device further includes: a dust pipe 6, one end of which is connected to the receiving area 11 and the other end of which is connected to an external dust removal device.
[0051] When the material enters the receiving area 11, some dust will be generated upward during the impact process. Therefore, a dust pipe 6 connected to the external dust removal equipment is provided on the top of the dust collector 1.
[0052] In one embodiment, such as Figure 2 and Figure 3 As shown, in order to further reduce the problem of dust overflow, a dust baffle 7 is provided at the discharge port 14 of the dust collector 1. The dust baffle 7 is made of a flexible material, such as a flexible plastic dust curtain or dust cloth.
[0053] In one embodiment, such as Figure 1 As shown, a connecting plate 8 is provided at the dust collection port 15 to facilitate the hanging of the dust collection box 3. The dust collection box 3 is slidably mounted on the connecting plate 8.
[0054] In one embodiment, such as Figure 1 As shown, in order to prevent the debris from accumulating directly on the ground, the dust removal device further includes a receiving frame 9, which is located below the discharge end 52 of the sorting pipe 5.
[0055] In one embodiment, such as Figure 1 As shown, since the negative pressure in the dust removal zone 12 is provided by external dust removal equipment, an airflow regulating valve 10 is installed on the sorting pipe 5 to prevent excessive negative pressure from sucking in too many large particles. After installation, the airflow regulating valve 10 is located between the external dust removal equipment and the dust removal pipe 4.
[0056] In one embodiment, such as Figure 4 As shown, in order to prevent the gravel entering the dust removal pipe 4 from accumulating inside the dust removal pipe 4, the dust removal pipe 4 is set at an angle downwards.
[0057] In one embodiment, such as Figure 5 As shown, in order to prevent gravel, dust and debris from getting stuck on the filter screen 2, a clearance opening 16 that communicates with the dust removal zone 12 is provided at the end of the filter screen 2 near the discharge port 14.
[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
