Embodiment 2

Based on Example 1, this example introduces a specific structure of a filter assembly 22 in a mining machinery grinding equipment. As shown in Figure 9, the filter assembly 22 includes a filter sleeve 23 fixedly mounted on the inner wall of the circular opening, and the outer wall of the filter sleeve 23 is provided with three arc-shaped openings distributed at equal distances. The inner walls of the three arc-shaped openings are fixedly connected with dust filter cloth 24. The bottom inner wall of the filter sleeve 23 is fixedly connected with an adjusting rod 36, and the outer wall of the adjusting rod 36 is fixedly connected with an adjusting seat 37. The outer wall of the adjusting seat 37 is fixedly connected with two electromagnets 38. The inner wall of the filter sleeve 23 is provided with two impact assemblies 28. The gap between the two electromagnets 38 is energized to generate a magnetism opposite to that of the second magnet 35, thereby attracting the second magnet 35 to move closer to the electromagnet 38. When the electromagnet 38 is powered off, the second spring 34 drives the impact seat 33 to pop out and impact the filter sleeve 23 to generate vibration, thereby shaking off the powder adhered to the dust filter cloth 24.

Working principle: When in use, the ore is injected into the feed hopper 2, and the ore is processed into powder through the processing of the crushing roller and the grinding roller in the equipment housing 1. After the processing is completed, the powder bracket is discharged through the discharge pipe at the bottom of the equipment housing 1. The powder adhering to the equipment housing 1 starts the vibration component 5 to clean it. During cleaning, the motor 14 starts to directly drive the half gear 15 to rotate. When the half gear 15 rotates, it directly pulls the drive column 10 through the rack 13. When the drive column 10 is collected in the vibration box 7, the spring 12 is compressed, thereby driving the drive column 10 to move back and forth and then driving the vibration seat 8 to impact the equipment housing 1 to generate vibration. A large amount of dust will be raised when the powder is discharged. At this time, the collection component 3 is started, and the fan 18 is started to suck the dust into the collection box 16 through the dust suction box 20, and through the filter sleeve 23. The dust filter cloth 24 on the filter is filtered, thereby leaving the dust in the collection box 16, so as to prevent dust from spreading and affecting the air quality. When the dust filter cloth 24 needs to be cleaned, the servo motor 27 drives the rotating shaft 25 to rotate, and then drives the magnet 1 30 on the fixed seat 29 to rotate. When the magnet 1 30 is facing the magnet 2 35, the magnet 2 35 is attracted to move toward the magnet 1 30, and then the impact seat 33 is pulled to compress the spring 2 34. When the magnet 1 30 is turned on, the spring 2 34 drives the impact seat 33 to impact on the filter sleeve 23. In the second embodiment, the two electromagnets 38 on the adjustment seat 37 are alternately energized to attract the magnet 2 35 on the impact assembly 28. When the electromagnet 38 is powered off, the spring 2 34 drives the impact seat 33 to pop out and impact the filter sleeve 23 to generate vibration, thereby shaking off the powder adhered to the dust filter cloth 24.
