Lead-zinc ore dust collector
1. Fine dust collector in lead-zinc ore, dust collector in lead-zinc ore beneficiation plant, shaker dust collector requirements and area:
Lead-zinc ore ore produces harmful mineral dust during the production process such as crushing, screening, transfer, etc. In order to prevent the dust from polluting the environment and make the indoor dust concentration meet the requirements of the "Design and Sanitary Standards for Industrial Enterprises", the dust production point is designed to be partially closed Use dust removal.
a. In the coarse crushing workshop, a dust removal point is set at the discharge place of the heavy plate feeder, and a dust removal point is set at the feed place of the jaw crusher to the 1 # belt conveyor, which is partially closed. The two are combined to form a mechanical cloth bag. Dust collector dust removal system, and Y-1 nozzle is used to spray water to the ore at the corresponding position to reduce the amount of dust. Air volume: 18000 ~ 22000m3 / h.
b. In the medium and fine crushing workshop, set one at each of the # 1 and 3 # tape conveyor heads, the medium and small tape feeders and the fine and small tape feeder heads, and the medium and finely crushed cone crushers to the 2 # tape conveyor feed. The dust removal point is locally closed. The six are combined to form a mechanical dust removal system, and Y-1 nozzles are used to spray water at the corresponding position to reduce the amount of dust. Air volume: 35000 ~ 45000m3 / h.
c. The screening room is provided with a dust removal point on the vibrating screen screen surface, the block discharge on the screen, the fine material discharge under the screen, and the ball mill feed belt receiving place at the bottom of the ore bin. Combine them to form a bag dust collector or a filter cartridge dust collector mechanical dust removal system and use Y-1 nozzles to spray water at the corresponding position to reduce the amount of dust. Air volume: 56000 ~ 65000m3 / h.
2.Technical requirements for fine crusher in lead-zinc ore, dust collector in lead-zinc ore dressing plant, and vibrating screen dust collector:
(1) Lead-zinc ore dust collectors have advanced performance, stable and reliable work, and should have advanced domestic standards.
(2) It is suitable for long-term heavy-duty working conditions in mines, with high production efficiency and low failure rate.
(3) Low operating cost, simple and convenient operation and maintenance.
(4) It has reliable motor protection functions such as overload, overcurrent, overvoltage, and undervoltage, and personal safety protection functions.
(5) The product quality conforms to relevant quality technical specifications or technical standards.
(6) The product stainless steel signs shall be fixed at appropriate and obvious positions. Its type and size shall comply with the requirements of GB / T 13306. The name of the manufacturer, equipment name, specifications and models, main technical specifications, factory number and date shall be clearly marked on the nameplate.
(7) All the equipment provided should be protected and coated on the surface according to the requirements of GB / T4879-1999.
(8) All equipment should be assembled and tested at the factory as far as possible.
(9) The lead-zinc ore dust collector is required to have high dust removal efficiency and good dust removal effect. The filtering efficiency of dust must not be less than 99.9%. After the dust removal treatment, the post dust concentration is ≤10mg / m3, which meets the requirements of the Occupational Exposure Limits for Hazardous Factors in the Workplace (GBZ2—2002); the dust concentration of the outlet gas is ≤50mg / m, which meets the requirements of the Lead-Zinc Ore Industry Pollution The requirements specified in the “Emission Standards for Wastes” (GB25466-2010); the residual gas pressure at the outlet is ≤1400Pa.
(10) The equipment design is compact, the structure is reasonable, the volume is small, and the area is small.
(11) Dust recovery does not require labor and does not cause secondary pollution.
(12) Low operation and maintenance costs. The service life of major components is more than three years.
(13) The electrical control cabinet of the lead-zinc precipitator includes the PLC automatic control system and the startup of the motor. The cabinet is computer gray. The main circuit breaker in the cabinet is ABB or Schneider. Relays, switches, etc. use Shanghai People's Electrical Appliances, Great Wall Electric, Liangxin Electric and other brands; micro-circuit breakers are not used in the cabinet, fuses are not used, and the busbars are insulated with heat shrink tubing. There should be independent neutral busbars and grounding busbars. . The inverter matched with the electric control cabinet adopts ABB, Danfoss or Schneider brand and is equipped with PROFIBUS communication interface. Take the cable down and out. The cabinet is made of cold-rolled galvanized steel, the thickness must not be less than 1.5mm, and the protection grade is IP65. Wiring diagrams and electrical control schematics are posted on the inside of the panel.
3. Lead-zinc ore dust collector, lead-zinc ore fine dust collector, lead-zinc ore beneficiation plant dust collector, vibrating screen dust collector includes: main body (upper, middle, lower box), fan, motor, filter material, solenoid valve , Air compressor, air cylinder, oil-water separator, diffuser box, screw conveyor, discharge valve, scraper, steam drum, air cannon, PLC control cabinet, etc.
