Cone mine crusher dust collector design meets emission standards

　　The cone crusher is a professional equipment for crushing medium and above materials. Generally, there are four kinds of crushing chambers such as coarse, medium, fine and superfine. In addition to sand, it can also be widely used in metal mines, cement plants, building materials industry, etc., for medium and fine crushing of various ores and rocks with compressive strength below 300Mpa, such as iron ore, non-ferrous metal ore, basalt. , granite, limestone, quartzite, sandstone, pebbles, etc.

　　The characteristics of the pulse filter cartridge according to the characteristics of the cone crusher are as follows:

　　1. The core filter element is a pleated _ filter cartridge, which greatly saves space compared with the ordinary bag filter.

　　2, the side is equipped with a maintenance door, which can be easily replaced, the installation and maintenance do not have to enter the fuselage, shortening the parking time;

　　3. All filters are automatically cleaned in sequence during operation, saving time and effort;

　　4. Drawer or ash bucket type cleaning structure can be used according to user needs;

　　The cone crusher dust collector will generate a large amount of fine dust during the work, which will cause serious pollution to the atmosphere. Workers must add dust removal equipment to the dust for a long time. Longtai Dust Removal Develops the special dust removal equipment for cone crusher for the dust characteristics of the cone crusher and the working environment of the crusher: pulse filter cartridge dust collector and pulse bag filter.

　　The cone crusher dust collector is generally operated under negative pressure. The dust-containing gas enters the tank through the air inlet. Under the action of the negative pressure in the folding filter cylinder, the air passes through the filter material from the outside of the cylinder and enters the cylinder, and enters the clean room to be discharged from the air outlet. . When the dust accumulates on the surface of the filter material and the resistance reaches the set value (can also be set by time),the pulse valve is opened, and the compressed air is directly sprayed into the center of the filter cartridge (core),and the filter cartridge is sequentially pulsed and cleaned. Let it resume low resistance operation.

　　In the field of mine dust collectors, there are solutions such as water spray, dust removal, vacuum dust removal, high-pressure electrostatic dust removal, etc. However, at present, the domestic poor open working environment, such as mines, has not found a true combined dust removal technology. For example, although water spray and dust removal are cheap, they have too much influence on the subsequent process, which is likely to cause secondary pollution of water; vacuum filtration and other methods are often criticized due to large investment, high energy consumption, and inconvenient maintenance. BME's bio-nano-dust suppression technology uses today's advanced bio-nano materials to mix dust suppression agents with objects to polymerize small particles of dust into large particles of dust. It turns the original so-called dust removal work into dust suppression and dust. Cured, won't fly. Its effective dust suppression rate is over 95%.

　　The cleaning of the dust collector of the mine is an important factor affecting the work of the equipment. The short cleaning cycle will affect the life of the cleaning equipment and the bag. The cleaning cycle is too long, which will affect the cleaning effect. The cleaning cycle and time of the mine dust collector should be adjusted according to the working conditions of the equipment.

　　d) Protect normal resistance. If the pressure difference is increased, it means that the filter bag is clogged, the water vapor condensation on the filter bag, the failure of the cleaning structure, the excessive accumulation of ash in the ash bucket, the blockage of the filter bag, and the increase in the air volume. The decrease in pressure difference may mean that the filter bag is damaged or loose, the air inlet pipe is blocked or the valve is closed, the tank or each compartment is leaking, and the auxiliary machine speed is slowed down. Announce an alarm when the pressure difference is exceeded, and promptly check and adopt the method.
