Description

Technical Field

[0001] The utility model relates to the technical field of sand suction equipment, in particular to a combined recoil sand and water suction machine. Background Art

[0002] The vacuum sand suction machine is a dust removal equipment used for pneumatic pipeline transportation of bulk particulate materials. The vacuum sand suction machines in the prior art all use filter elements to filter and remove dust. The dust adhered to the outer surface of the filter cartridge is all removed by back-blowing pulse spraying through compressed air through a pulse valve. The dust is sucked into the cyclone dust collector through the sand suction pipe for cyclone separation. The gas with a small amount of dust is then filtered and dusted through the filter cartridge. A large amount of dust is adhered to the outer surface of the filter cartridge, and then the compressed air is timed to control the pulse back-blowing from the inside to the outside of the filter element to remove the dust. When the existing vacuum sand suction machine is sucking sand, a large amount of dust will adhere to the filter cartridge. Compressed air is used to pass through the pulse valve for pulse back-blowing and spraying to remove the dust. The dust removal effect not only depends on the pressure, temperature and water content of the compressed air, but also consumes a large amount of compressed air, resulting in serious waste of electric energy. A large amount of dust adheres to the outer surface of the filter cartridge and is not easy to be blown away, resulting in increased suction resistance and reduced sand suction capacity.
