Coke screening is an essential part of the coke plant, coke is a hard texture, formed by carbon substances bonded to each other lumps, in the screening process will produce wear and tear, so in the process of coke screening, the need for regular inspection of equipment, maintenance and replacement of parts, the existing coke screening equipment, screen plate material is mostly polyurethane, casting stainless steel, stacked welding based on the coke in the sieve plate walking Speed 0.3m/s, 200T/h capacity, for example, the screen plate fixing bolts in the absence of protection, wear and tear is serious, the screen plate will be used every 3-4 months will appear fracture or even wear through the phenomenon, need to be replaced in a timely manner, in the replacement of the need to shut down and cool down after the cutting of the screen plate bolts, due to the limitations of the upper layer of the screen plate, cutting the lower layer of the screen plate bolts of the space is very narrow, only 0.6m, workers can only prostrate operation, small space operation is difficult, in such a way, the screen plate is very narrow. The space is small and difficult to operate, in such a narrow space to complete the cutting of screen plate bolts, replace the new screen plate, install the fastening bolts, is a great test, replace a set of screen plate 8 workers at the same time to operate needs 72h (2665 vibrating screen as an example), to be the normal operation of the equipment 48h after the second shutdown and tighten the bolts, which not only consumes manpower and material resources, but also greatly reduces the production efficiency.
My company's Zhangqian ceramic powerless coke screen, screen plate using 92% AL2O3, can do 5 years of maintenance-free, free of replacement of the screen bar, the design of the screen unit structure for quick dismantling type, easy to install, 3h rapid adjustment of the screen hole aperture, easy to adjust, adjust the range of 0-100mm, in order to cope with the changes in the market at any time to make adjustments, to meet the needs of coke various specifications of the screening.
Zhangqian ceramic powerless coke sieve has the following advantages:
1, no high-frequency vibration, reduce coke friction with each other crushing rate of up to 1.2-1.8%.
2、Long life design, ceramic screen plate can do 5 years maintenance-free, no replacement of screen bars.
3、Saving the cost of accessories, annual savings of electricity, screen panels, shakers and other accessories cost 80-1 million.
4、Screening unit is quick disassembly type, 3h quick adjustment of sieve aperture, adjustment range 0-100mm.
5、Good dust removal effect, improve the negative pressure of the dust removal port 50%, the site is clean.
6, reduce the labor intensity of workers, three years overall no maintenance projects, workers are more relaxed.
7、Using new type European wing observation door, convenient for observation and maintenance.
