Improved method for disc face of vertical disc filtering machine

Abstract

The invention provides a vacuum vertical disc filtering machine which has a plurality of advantages of high yield, reliable work, convenience for maintenance and the like due to a very developed technology and gradually turns into a mainstream device for a filtering procedure. However, the vertical disc filtering machine has the disadvantages in an actual production process that the disc face is deflected to be clamped; a disc hoop and a fan plate are deformed and a clamping pin on a fan plate spring is easy to fall off; the alignment of the disc face and the disc hoop is poor; a steel plate on the side face of a half-moon-shaped groove is abraded to cause material leakage; the service cycle of filtering cloth is short; a connection pipe part of the fan plate and a central shaft, a filtering cloth connection part and the filtering cloth are damaged so that the air leakage is caused and the vacuum degree is reduced; the central shaft moves and the like. The vertical disc filtering machine is improved by a partial improvement and disc face reinforced improvement method; after being improved, the vertical disc filtering machine can continuously operate for long time except exchanging the filtering cloth; the service cycle of equipment is prolonged greatly; the staring and stopping frequencies are reduced and the labor intensity of workers is reduced; meanwhile, a disadvantage link in the operation of a work flow is eliminated and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a method for improving the disc surface of a vertical disc filter. Background technique [0002] Vacuum vertical disc filter is one of many filtering equipment, and it has been widely used in many industries such as coal and non-ferrous smelting in my country in recent years. Due to its mature technology, high production capacity, reliable operation, and convenient maintenance, it has almost completely replaced the old-fashioned drum filter and gradually become the mainstream device in the filtration process. Import of Aluminum Corporation of China Zhongzhou Branch 152m 2 Vertical disc filter has large disc diameter, large filtration area, high rotation speed, large capacity, although there are many fan plates, it is small in size and light in weight, easy to disassemble, fast to replace small cloth, and the blowback volume per rotation is small. The advantages of low consumpti...

Problems solved by technology

[0005] In order to overcome the above-mentioned plate deflection being stuck, causing the equipment to jump and stop, the hoop and fan plate are deformed, the outer edges of the hoop are concave and uneven, the radian changes, and the fan plate is bent and twisted; The bayonet pin is easy to fall off, causing the leaf spring to be skewed and the leaf to be disengaged, the leaf to rotate, the leaf to come off the side edge of the hoop, and the leaf to be misaligned in the axial direction and circumferential direction. Skew, poor alignment between the disk surface and the hoop ring, the alignment cannot be adjusted, and the disk surface is deflected; the steel plate on the side of the half-moon groove is worn through, and the material leaks; the service life of the filter cloth is short; the connecting pipe between the fan plate and the central axis, and the filter cloth are connected Insufficient air leakage and vacuum degree drop caused by damage to the filter cloth; the lack of serial movement of the central axis, the invention provides a method for improving the surface of the vertical filter machine
