Background
The classifier tank body is obliquely arranged on the foundation, the bottom surface of the tank body forms 14-18.5 degrees with the horizontal, and a sedimentation area is formed in the tank at the overflow end. The ore pulp discharged from the mill enters a settling zone in the classifier from the side surface of the tank body, and is influenced by the stirring of the spiral body, small particles in the ore pulp float on the surface of the liquid, are discharged from an overflow weir (low end), and large particles are discharged from a sand return end (high end), so that the purpose of classification is achieved. The lower end bearing position of the classifier can be two choices, one is arranged in the tank body, and the other is arranged outside the tank body.
In the first method, the bearing at the low end is arranged in the groove body, so that ore pulp easily enters the bearing to cause damage to the bearing; after the wear-resistant rubber and nylon sleeve are used, the service life of the nylon sleeve is about 2-3 months, and the nylon sleeve needs to be replaced frequently. The low-end bearing of the second method is placed outside the tank body, water leakage can occur after the low-end bearing is used for a period of time, and the sealing part of the low-end bearing and the tank body is worn and is difficult to repair.
Because the sealing is built in the ore pulp, the sealing service time is short before the sealing is key, so that the abrasion of the low-end bearing is quick, and the service life is influenced, and the technical staff designs a sealing structure for the built-in low-end bearing of the classifier so as to solve the problems.
