Description
Technical Field
The invention relates to a floating screen frame, in particular to an integrated multilayer floating screen frame.
Background
As is well known, ore grinding is the most energy-consuming process in the mining field, and "grinding with more breaks and less grinds" has become a consensus in the industry, so that the reduction of the grinding grain size is the key to energy conservation. In a conventional screening machine with a fixed screen surface and a micro powder screen surface combined, the size of a lower-layer screen is about 6 mm. The lower layer sieve surface of the double-layer micro powder sieve can be used for grading with the sieve mesh size below 1mm, and the upper layer sieve mesh can be controlled to be about 6mm for coarse separation. Therefore, the grinding granularity of the double-layer micro powder sieve is greatly reduced, and the double-layer micro powder sieve furthest exerts the lamination crushing advantage of the high-pressure roller mill by obtaining smaller grading granularity, so that the aim of saving energy can be fulfilled.
The structure of the current common double-layer micro-powder sieve is as follows: an upper layer screen frame unit and a lower layer screen frame unit are arranged between the two side plates of the screening machine; each layer of screen frame unit comprises fixed cross beams and floating cross beams which are arranged at intervals, and two ends of each fixed cross beam are fixedly connected with two side plates of the screening machine to form a fixed screen frame; after each floating cross beam passes through the side plates of the screen machine, the floating cross beams are connected by continuous floating rectangular pipes positioned outside the side plates of the screen machine to form a whole, namely a floating screen frame, and the floating screen frame can perform floating movement relative to the side plates of the screen machine. The working principle is as follows: the vibration exciter drives the fixed screen frame to vibrate, and the fixed screen frame drives the floating screen frame to move.
The upper layer floating screen frame and the lower layer floating screen frame of the double-layer micro-powder screen are independent and not connected, and the whole screen machine is a three-mass system. Therefore, there are the following problems: (1) The amplitude of each layer of floating screen frame is greatly influenced by materials, and once the distribution of the materials fluctuates, the amplitude of the upper layer of floating screen frame and the lower layer of floating screen frame can change, so that the adjustment is very difficult; (2) The amplitude variation of the upper and lower floating screen frames not only influences the screening effect, but also has adverse effect on the structure of the screening machine, and increases the problems of torsional vibration, polarization and the like.
The multilayer micrometric sieves also present the problems mentioned above.
