Description
Technical Field
The utility model belongs to the technical field of classifier equipment, and relates to an anti-blocking vibration device for an overflow screen of an ore grinding classifier.
Background
The classifier is widely applicable to the particle size classification of ore pulp in a metal ore dressing process, and can also be used for desliming and dehydration in ore washing operation, and a closed-circuit process is formed by the classifier and a ball mill. The classifier has the characteristics of simple structure, reliable operation, convenient operation and the like, and by means of the principle that the sizes of solid particles are different and the specific gravities are different, so that the sedimentation speeds in liquid are different, fine ore particles float in water to overflow, coarse ore particles sink at the bottom of the tank and are discharged from the upper part by spiral pushing, the classifying equipment for mechanical classification can be used for classifying the materials ground in a mill into the powder for filtration, then the coarse material is screwed into a feed inlet of the mill by utilizing a spiral piece, and the filtered fine material is discharged from an overflow pipe.
At present, with the continuous improvement and development of modern mineral separation ball mill graders, the mineral separation ball mill grader meets the requirements of the mineral quality of the conventional ball mill grader, and the mineral separation equipment can produce products with higher precision and higher grade. As shown in the schematic diagram of the prior classifier in fig. 1, the classifier comprises an integral classifier bracket 1, one end of the classifier bracket 1 is provided with a driving motor 2, the other end of the classifier bracket is provided with an overflow groove 5 for screening fine ores, a classifier rotating shaft 3 connected with the driving motor 2 is arranged on a bracket body of the classifier bracket, classifier blades 4 for pushing coarse ores to the upper part of the classifier for discharging are arranged on the classifier rotating shaft 3, the whole overflow groove 5 is in a rectangular frame state, one side close to the classifier blades 4 is provided with an overflow surface 7, the bottom end of the classifier bracket is rigidly connected with an overflow screen 6, and a plurality of overflow screen holes 8 are uniformly arranged on the overflow screen 6. Currently, classifier overflow screens are widely used in the filtration of ore media, an important component of the mill equipment, for transporting acceptable products through the overflow screen to the next process for operation, and unacceptable products are discharged upwardly through classifier blades 4 and fed into a ball mill for secondary grinding until acceptable products enter the next process through the classifier overflow screen. Because the ore mediums are different, and the ore is excessive in internal impurities in the transportation process, when the ore is ground in a ball mill, particles containing impurities in the ore mediums flow to an overflow screen of the classifier more easily, normally the overflow screen of the classifier adopts a screen with 200 meshes or other meshes, excessive impurities are precipitated through the inside of the classifier, light ore mediums meeting the requirements flow to the next process through the screen with 200 meshes, and if the lighter mediums in the ore are more than or equal to 200 meshes, the lighter mediums cannot reach the next process through the screen, and the overflow screen of the classifier is blocked; in addition, even ore media smaller than-200 mesh, when multiple pieces of ore media are gathered together, the screen tends to be blocked; after the overflow screen of the classifier is blocked, serious influence can be brought to production, and serious pollution can be brought to the environment of the whole factory building, so that the whole factory building is always filled with ore pulp everywhere, once the ore pulp leaks from the inside of a chute to the outside, the leaked ore pulp cannot be recovered, great economic loss can be brought to enterprises, and great potential safety hazards can be brought to other equipment. In addition, clogging of the classifier overflow screen also presents the following problems: 1. the labor intensity of workers is increased, equipment needs to be cleaned and dredged, and the production progress is influenced; 2. the ore pulp affects the environment and the lubrication of the equipment, increases the friction of the rolling part of the equipment, and shortens the service life of the equipment after long-term use; 3. and is prone to abnormal wear of other mechanical parts.
