Description

[0001] The utility model relates to the technical field of ore pulp processing, in particular to a screen plate cleaning mechanism at a discharge end of a classifier. Background technology:

[0002] The ore is processed by the ball mill and then enters the classifier. After being processed by the classifier, it is discharged from the discharge end of the classifier into the slurry pump. The impurities in the slurry are filtered through the sieve plate at the discharge end of the classifier to prevent the impurities from entering the slurry pump and reducing the quality of the raw materials. The long-term use of the sieve plate requires manual shoveling of the filtered impurities.

Workers are required to repeatedly insert the cone rod into the sieve holes from the top of the screen plate to clean it. The impurities will be pushed from the top of the screen plate to the bottom of the screen plate by the cone rod and mixed into the slurry and enter the slurry pump, reducing the quality of the slurry.

[0024] The diameter of the through hole on the top surface of the orifice plate 4 is larger than the diameter of the sieve hole on the sieve plate 2, so that the slurry falling on the top surface of the orifice plate 4 can flow out along the through hole on the top surface of the orifice plate 4, thereby preventing the slurry from accumulating on the top surface of the orifice plate 4.

The principle of labor-saving lever is adopted, so that the pressure rod 8 is pressed with less effort.

[0030] Please combine Figure 1 As shown, during use, when the sieve holes of the sieve plate 2 need to be cleaned, the staff repeatedly presses one end of the pressure rod 8, the pressure rod 8 drives the through groove 9 to slide on the slide rod 7, the pressure rod 8 drives the slide rod 7 to slide, the slide rod 7 drives the orifice plate 4 to slide, and the orifice plate 4 drives the cone rod 6 to repeatedly move and insert into the sieve holes on the sieve plate 2 to clean the sieve holes.
