Downflow Dust Collector For Sand Blasting Room

1. Blow air access convenient 
2. Small maintenance workload. 
revolving reverse blowing industrial bag filter dust collector

Working principle

 

Dust enter into the dust collector by air inlet along the tangent direction, the air flow rotating in the lower cylinder. Under the action of the centrifugal force and gravity, particle size larger dust separation along the wall down into the hopper. And the fine dust rising with air, after radial arrangement of trapezoid (round or oval) filter bag filter, dust be trapped filter bag outside. To purify the gas through the filter bag from net filter bag into the top of the chamber by trachea. Continuously to stay in the outside of the filter bag dust layer thickening, resistance to the set value, automatic start the blower, with enough momentum of blowing, by cantilever duct through a nozzle blow filter bag, filter bag vibration caused by shake filter cake; When the filter bag resistance to lower limit, the blower stop working automatically. In circulation, implementation of precipitator dust, soot and dust collection.

 

Safety facilities:

 

(1) The relief valve. When dust catcher to pulverized coal processing and combustible gas, each device design and install two groups of heavy hammer type safety explosion at least.

 

(2) Ladders, railings and walk filter in the design and installation, must be in conformity with the GB 4053.1 1993 fixed type steel ladder [, "GB 4053.2 1993 stationary steel inclined ladder", [4053.23 GB - 1993 fixed industrial protective railings", [GB 4053.4 1993 stationary industrial steel platform".

 

(3) The design and installation of dust catcher, scientific temperature control, ensure internal flue gas dust collector temperature above the acid dew point, preventing fouling and condensation bag filter.

 

Matters needing attention:

 

(1) Ash hopper, filter chamber shell, clean room for each manhole door. Explosion door, observation hole between the flange should be embedded into the sealed fill material to tighten the bolt, to prevent air leakage.

 

(2) the ceiling board trapezoid hole should be vertical with the corresponding location on the bottom bracket circle. To prevent skewed gas leak into the frame after the filter bag.

 

(3) Blow slewing transmission mechanism, it should pay attention to vertical in installation. To up and down the arms swing plane and the mouth of the framework to guide line. Keep 2 ~ 4 mm distance, rotating flexible, tuyere turn-over device, a clash of heads with position properly

 

(4) The filter bag from the set of filter bag on the outside, should layering compaction, and prevent leak. Then carefully insert into ceiling board,( 54748651, 54748452, 54662644,note that don`t make the filter bag cut or scratch) tail cone pin inserted into the bottom bracket circle of corresponding location, after the upper guide frame mouth slot neatly aprons with press, pin pressure.

 

(5) Cover the roof, we should try its rotation flexible. Roof and clean outdoor application rubber seal ring junction, by complete sealing under roof.

 

(6) after the installation, filling lubricant to the transmission parts. And then try to check the reducer connection whether reverse turn, such as inversion of rewiring immediately, in order to avoid attaint parts.

 

(7) the transmission parts shall be oiling regularly during the operation, and should be regularly check the jib. Since the reverse blowing control system should be checked regularly, prevent failure.
