Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, and in particular to a dust removal device for a vertical mill. Background Technology

[0002] Vertical roller mills are ideal large-scale grinding equipment, widely used in industries such as cement, power, metallurgy, chemical, and non-metallic minerals. They integrate crushing, drying, grinding, grading, and conveying, offering high production efficiency. They can grind lumpy, granular, and powdery raw materials into the required powdered materials. However, feeding raw materials into a vertical roller mill generates a large amount of dust, requiring the use of dust removal devices to prevent harm to workers' health.

[0003] A search revealed a public disclosure (announcement) number: CN213050874U, which discloses a dust removal device for vertical roller mill processing. The device includes a mill body and an electrostatic dust removal mechanism. The electrostatic dust removal mechanism is arranged on the circumference of the mill body. It also includes a dust removal mechanism located at the bottom of the electrostatic dust removal mechanism. This invention utilizes the dust removal mechanism to completely remove dust.

[0004] Although the above solution can completely remove dust using a dust removal mechanism, it is difficult to separate and collect large particles of impurities and dust during the dust removal process. Cleaning large particles of impurities and dust is not convenient, and it is difficult to adjust the orientation of the dust removal device, resulting in poor dust removal effect. Utility Model Content

[0005] The main purpose of this utility model is to provide a dust removal device for a vertical mill. By setting an air intake unit, it solves the problem that it is difficult to separate and collect large particles of impurities and dust during the dust removal process, and that it is not convenient to clean large particles of impurities and dust. By setting an adjustment unit, it solves the problem that it is difficult to adjust the orientation of the dust removal device, resulting in poor dust removal effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dust removal device for a vertical mill includes a base, a controller disposed on the front of the base, an air intake unit disposed on the top of the base, and an adjustment unit disposed inside the base.

[0008] The air intake unit includes a connector at the top of the base, a hinge on one side between the connector and the base, an air intake component inside the connector, and a filter component at the top of the air intake component.

[0009] The adjustment unit includes a propulsion component disposed inside the base, a slide groove opened on one side of the bottom end of the connecting seat, and a snap-fit ​​groove connected to the front and rear sides of the slide groove.

[0010] Preferably, the suction components in the suction unit include a suction machine disposed inside the connecting seat, a heat dissipation hole opened in the middle of the bottom end of the connecting seat, a fixed column fixedly connected to the top of the suction machine, a breathable mesh inclinedly disposed inside the bottom end of the fixed column, a transmission tube connected to one side of the fixed column, and a filling box disposed at one end outlet of the transmission tube.

[0011] Preferably, one end of the material box in the suction unit is flush with one side of the connecting seat, and the transmission tube is inclined.

[0012] Preferably, the filter assembly in the air intake unit includes a detachable column disposed at the top of the fixed column, two placement slots opened inside the detachable column, a snap-fit ​​block disposed inside the placement slot, a connecting ring fixedly connected between the two snap-fit ​​blocks, a screen fixedly connected to the bottom of the connecting ring, a barrier ring fixedly connected to the top of the connecting ring, a vertical rod fixedly connected to the top of the snap-fit ​​block, and a limiting block fixedly connected to the top of the vertical rod.

[0013] Preferably, the filter assembly in the intake unit further includes an extension ring disposed at the bottom of the detachable column, a plurality of through holes opened on both sides of the extension ring, and a plug rod disposed on the front of the fixed column and extending into the corresponding through hole.

[0014] Preferably, the propulsion component in the adjustment unit includes a cylinder disposed inside the base, a telescopic column disposed at the top of the cylinder, and protrusions fixedly connected to both sides of the telescopic column.

[0015] Preferably, the telescopic column in the adjustment unit is engaged with the slide groove, and the protrusion is engaged with the corresponding engagement groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. In this utility model, by setting up an air suction unit, the air suction machine is started by the controller. The air suction machine draws air from the feed port of the vertical mill through the fixed column and the detachable column, sucking in the gas and dust near the feed port of the vertical mill into the detachable column. Large particles of impurities in the dust are filtered by the screen. Then the gas and smaller dust particles enter the interior of the fixed column. The smaller dust particles are blocked by the air-permeable screen. The gas is discharged through the air suction machine. At the same time, the smaller dust particles enter the loading box under the action of the conduction pipe. In this way, large particles of impurities and dust are separated and collected. The limit block can be pulled upward to bring out the connecting ring and the large particles of impurities on the screen. At the same time, the loading box can be pulled out to clean the dust inside, thus improving the working efficiency of the dust removal device.

[0018] Second, in this utility model, by adjusting the unit, the cylinder is activated to extend the telescopic column, which in turn moves the protrusion in the snap-fit ​​groove, and at the same time moves the connecting seat upward. This causes the connecting seat to rotate along the hinge, and at the same time changes the angle of the fixed column and the detachable column. This allows the orientation of the dust removal device to be adjusted, thus optimizing the dust removal effect. Attached Figure Description
