Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a positive pressure dust removal device for a cone crusher. Background Art

[0002] Cone crushers are widely used in metallurgy, construction, road construction, mining, stone quarries and other industries. They can crush various ores and rocks of medium and above medium hardness. When working, the rotation of the motor passes through the pulley or linkage shaft, the cone crusher drive shaft and the cone part of the cone crusher, which are forced by the eccentric sleeve to make a swinging motion around a fixed point, so that the crushing wall of the crushing cone sometimes approaches and sometimes leaves the surface of the mortar wall fixed on the adjustment sleeve, so that the ore is constantly impacted, squeezed and bent in the crushing chamber to achieve the crushing of the ore. When the cone crusher is working, the material is crushed in the crushing chamber and a large amount of dust is generated. The dust can enter the main machine through the gap between the slip ring cover and the crushing wall, thereby affecting the normal operation of the cone crusher;

[0003] The existing dust treatment method is often to install an air circulation device on the outside to circulate these dusty particles, and then circulate clean air into the cone crusher. A filter is installed in the middle of the air circulation device to continuously filter the dust in the air.

[0004] This method of adding filters has some problems in actual operation. It cannot classify large particles of debris and dust-containing particles. The filter is hit by the debris for a long time, which shortens its service life. For this reason, we propose a positive pressure dust removal device for cone crusher. Utility Model Content

The mounting frames are respectively fixedly connected to the middle of the two baffle plates. Evenly distributed support rods are arranged between the two baffle plates. The outer surfaces of the support rods are fixedly connected to a filter screen. The middle part of the dust hood is rotatably connected with an arc-shaped steel scraper. The outer arc surface of the arc-shaped steel scraper away from the center of the air inlet hood contacts with the inside of the filter screen, and different types of turbid matter are classified and collected, thereby extending the service life of the dust removal device. The debris on the filter screen can be removed in time to avoid being hit by the debris for a long time and shortening the service life.

[0009] Furthermore, it also includes a control switch, which is arranged on the left side of the front side of the lower blocking plate, and the input end of the control switch is electrically connected to an external power supply to control the normal operation of the motor.

[0010] Furthermore, the dust removal mechanism also includes a bottom bracket, which is arranged in the middle of the lower mounting frame, and the middle of the bottom bracket is rotatably connected to the lower end of the transmission rod to realize the function of the bottom supporting the transmission shaft.

[0011] Furthermore, it also includes a reduction motor, which is arranged in the middle of the upper surface of the dust cover, the output shaft of the reduction motor is fixedly connected to the upper end of the transmission rod, and the input end of the reduction motor is electrically connected to the output end of the control switch to provide power for scraping dust.

[0012] Furthermore, it also includes a dust removal groove, which is opened at the lower end of the air inlet hood, and a dust removal drawer is inserted into the dust removal groove to achieve the function of containing large particulate matter.

[0013] Furthermore, it also includes a dirty air outlet pipe, which is arranged in the middle of the right side of the dust hood, and the right end of the dirty air outlet pipe is connected to an external dust collecting device to achieve the function of dirty air collection.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the positive pressure dust removal device of the cone crusher has the following advantages:

[0016] When it is necessary to perform dust removal operation of the cone crusher, the control switch can be adjusted, the reduction motor can be operated, the output shaft of the reduction motor can be operated, and then the arc-shaped steel scraper is driven by the transmission rod to continuously scrape the inner surface of the filter. At this time, the cone crusher is running, generating a large amount of dirty air. The dirty air enters the inner wall of the air inlet hood along the air inlet pipe, and then goes up into the interior of the box. Then the dirty air is filtered by the filter and enters the sandwich between the filter and the inner surface of the air inlet hood, and then is discharged to the outside of the device along the clean air outlet pipe.
