Abstract
Disclosed is a novel pipeline pneumatic powder delivery feeding metering system. A gate valve is mounted below a bin, a feeding screw is mounted below the gate vale, a fully sealed electronic belt weigher assembly is connected to the lower side of the feeding screw, a pressure equalizing bin is connected to the lower side of the fully sealed electronic belt weigher assembly, an air locking pump is connected to the lower side of the pressure equalizing bin, and material is spirally delivered to a pneumatic delivery pipeline through the air locking pump. The metering system overcomes affection of return air of the pneumatic delivery pipeline upon the metering precision, can guarantee stable and higher metering precision equal to or less than 0.5% for powder feeding systems of pneumatic delivery pipelines with pressure equal to or less than 0.3MPa.
Description
Technical field:
The utility model relates to a kind of feeding metering device, specifically is meant a kind of novel pipeline strength conveying powder material feed metering system, can be widely used in the granular material feed metering that industries such as building materials, metallurgy, coloured industry are carried with strength.
Background technology:
At present, for the feed metering of pipeline strength conveying powder material, ubiquity the problem of wind effect to measuring accuracy of returning of Pneumatic conveying pipeline.And the pipeline blast is big more, and is obvious more to the influence of measuring accuracy, and the lock wind measure of taking usually all only is applicable to the low pressure that 0.05mpa is following.
Summary of the invention:
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of novel pipeline strength conveying powder material feed metering system, can guarantee stable higher measuring accuracy, precision≤0.5% for Pneumatic conveying pipeline pressure 0.3mpa and following granular material feeding system thereof.
The technical solution adopted in the utility model is: under feed bin gate valve is installed, the feed spiral is installed under gate valve, connect full-closed electronic belt conveyer scale assembly under the feed spiral, under full-closed electronic belt conveyer scale assembly, connect and all press the storehouse, connect the lock air pump under the storehouse all pressing then, material by lock air pump helical feed to Pneumatic conveying pipeline.
In the technique scheme, full-closed electronic belt conveyer scale assembly is that the electronic constant belt conveyer scale is installed in the pressure shell, and the electronic constant belt conveyer scale is installed dust stratification chain scraper machine down.
In the technique scheme, the feed spiral is the feed spiral of lock wind, current stabilization.
In the technique scheme, the lock air pump adopts the spiral pump of lock wind.
In the technique scheme, electronic constant belt conveyer scale and dust stratification chain scraper machine adopt the matured product of existing Chaofan Computer System Co., Ltd., Changsha or Changsha precision instrument and equipment Co., Ltd free from worldly cares.
The utility model is a feed metering lock wind system, thereby overcome the problem that Pneumatic conveying pipeline in the prior art returns the wind effect measuring accuracy, the utility model system can guarantee at 0.3mpa and following granular material feeding system thereof a stable higher measuring accuracy, precision≤0.5% are arranged for Pneumatic conveying pipeline pressure.
Description of drawings:
Fig. 1 is the utility model structural representation
The accompanying drawing marking explanation:
1---gate valve 2---feed spiral
3---full-closed electronic belt conveyer scale assemblies 4---are all pressed the storehouse
