Close envelope.
Installation process:
1), first by head 1, changeover portion 4, the first interlude 6, maintenance section 7, the second interlude 15, the hexagonal spiral shell of tail portion 16
Bolt 8, spring shim 9, plain washer 10, hex nut 11, graphite grazing pad 12, high-temperature seal adhesive 13 connect, then solid again
It is scheduled on supporting leg 17.
2), then flight chain 5 is installed around head 1, tail portion 16, then head 1, driving device 3 are used transmission chain
Item 2 connects, and finally according to on-site actual situations, feed opening 14 is welded on interlude 15, this part is that dedicated bury is scraped
Plate conveyor body part.
3), then, nitrogen interface 18, fire water interface 19, thermometer 20, pressure gauge 21, venting of dust explosion mouth 22, oxygen content are examined
It surveys instrument 23, nitrogen discharge valve 24 etc. and is welded on main part corresponding position.
4) control cable, the power cable on all motor and detecting element finally, are accessed into electric cabinet 25 on the spot
Entire dedicated bury is controlled in (band DCS remote control interface), and on from central control room DCS lead to oxygen content testing instrument 23 to scrape
The operation of plate conveyer, this part are bulk material conveying equipment intelligence explosion protection system.
Working principle:
1) before, conveying graphite cathode raw material, the solenoid valve of nitrogen interface 18 is first controlled to dedicated embedded scraper transporter machine
Nitrogen is poured in vivo, until oxygen content testing instrument 23 shows oxygen concentration≤100ppm, shows pressure in body on pressure gauge 21
For 10-30Pa.Meanwhile by water inlet pipe 28 to being passed through cooling water in water leg 27.Then, it controls under scrapper conveyor upstream equipment
Material, material pass through feed opening 14 after, can by two-stage deflector chute 26 by material be directed into bottom plate trough (in fall zigzag shape), then by
Driving device drives flight chain 5 to operate, so that material is transported to head discharge mouth discharging, during this, flight chain 5 is not
It is contacted with material, only scraper plate is contacted with material.
2), in the process of running, bulk material conveying equipment intelligence explosion protection system is constantly in monitoring and analysis state to material,
If detecting that oxygen concentration > 100ppm, DCS control system can control to adjust the solenoid valve of nitrogen interface 18, thus
Accelerate to nitrogen is poured in vivo, until oxygen concentration is qualified.
3), when temperature or air pressure are more than level-one preset threshold, alarm signal is issued, while among DCS system control equipment
Accident nitrogen charging mouth be filled with a large amount of nitrogen into cavity and open the solenoid valve at top nitrogen discharge outlet 24, reach pressure release and resistance
Combustion prevents temperature from increasing.
If 4), the above processing is not up to expected effect, equipment downtime when temperature is more than second level preset threshold is beaten automatically
It is explosion-proof to open the implementation fire extinguishing of fire water interface 19, and stops the operation of whole system.
5), the use of venting of dust explosion mouth 22 is when reaching dangerous air pressure in equipment cavity, to crush the thin aluminum sheet on 22 top of venting of dust explosion mouth, make
The intracorporal air pressure of chamber obtains instantaneous relase, eliminates the danger of explosion.
Above-mentioned apparatus can integrate self seal and sealing transport is realized in nitrogen-sealed, by using made of heat-resisting material
Equipment and the reduction of equipment vulnerable part contact with high-temperature material and realize high temperature resistant resistance to compression, by the way that easy-opening access hole is arranged, are damaging
When can Quick overhaul, improve the practical performance of whole equipment.
