Description
Technical field
The utility model is related to measurement technology apparatus field, suitable for rotor claims transformation particularly with regard to a kind of
Coal mixer.
Background technology
Rotor claims to be at present in a kind of more equipment of cement industry coal powder metering；In terms of service condition, there is many
Rotor claims rate of load condensate to be fluctuated between 60%-80%, can frequently occur disconnected coal phenomenon when particularly producing in the winter time, have a strong impact on
What is produced is normally carried out.Many factories take the trial of a variety of modes to this, such as increase heating tape in Pulverized Coal Bin tapering
And insulation；The small storehouse of increase buffering metering (capacity for reducing Pulverized Coal Bin raises tapering)；Set up and help stream air；Set up or increase and gather dust
Dust-collecting pipe is linked into main dust-precipitator etc. by pipeline.These modes have plenty of reduction and resolve coal number of times, and what is had but changes poorer and poorer.
Such as Wuhu factory 5000t/d production lines, kiln hood is claimed using DRW4.12 kiln tails using DRW4.14 Fes spy, and broken since the operation coal
Phenomenon takes place frequently, and especially dore furnace hello coal is more frequent, is contacted in the case where the various methods of trial are had no result with genuine man, to dividing
Solution stove feeds coal and claims to have carried out the small storehouse of increase buffering metering (capacity for reducing Pulverized Coal Bin raises tapering and meets setting height(from bottom), increase lock
Wind feeding valve etc.), though not being fully solved disconnected coal phenomenon after transformation compared with before transformation, coal number of times is resolved in reduction.It is again right afterwards
Kiln hood coal claims to have carried out after same transformation, implementation result completely on the contrary, being originally three days disconnected dants, changes and at least breaks three one day after
Dant.
It is considered that causing rate of load condensate is too low, fluctuate the big and disconnected coal phenomenon that takes place frequently to be that rotor claims design to produce in itself.Turn
Sub- scale is the scale body of integration, and mixed coal technique is inside rotor weigher main frame, and pressure is pressure of delivering coal in rotor, and coal dust silo roof
For negative pressure, there is huge pressure difference.Rotor claims rotor during work to need to rotate, and must just have gap, although to turning on operation instructions
There are a strict requirements in sub- gap, but is difficult to be adjusted in place in, or because uneven wear can not pass through again after being adjusted in place
The mode of adjustment returns to home position requirement, and some rotors claim to cause service condition more because processing assembly precision does not catch up with
Difference.
Utility model content
Technical problem to be solved in the utility model：Design for prior art is unreasonable, and rate of load condensate is low, there are
The heavy wear of huge pressure difference, rotor and sealing plate, maintenance cost and there is provided a kind of structure the problem of take high using material cost
Simply, it is reasonable in design, claim internal air pressure to be less than orlop coal dust material pressure after transformation, gas is no longer played a reversed role to charging aperture so that coal
Air content in powder greatly reduces, and rate of load condensate is high, and blanking is smooth, and the degree of wear is low, and service life is high, maintenance cost and uses
Material cost takes the low coal mixer that rotor claims transformation that is applied to.
Technical problem to be solved in the utility model can adopt the following technical scheme that to realize：
It is a kind of to be applied to the coal mixer that rotor claims transformation, it is characterised in that including a pump housing, the pump housing and rotor weigher
Top original air inlet is connected, and the side of the pump housing is provided with an anemostat, one end of the anemostat is provided with a spray
Mouth extends to the side of the pump housing, and the other side of the pump housing is provided with square chest, be provided with the square chest air inlet tube with
And an adjusting apparatus, one end of the air inlet tube is provided with a tuyere and extends to pump body, in the another of the air inlet tube
One end is provided with the attachment means for being used to be connected with check-valves, and one end and power set, the rotor of the check-valves deserve to be called portion
Deliver coal one end of the mouth of pipe and bottom airduct of original is connected, and the other end of the bottom airduct is provided with an air inlet being connected with gas tank side
Valve, a soot cleaning valve is provided with the opposite side of the gas tank.
In a preferred embodiment of the present utility model, the side of the pump housing is provided with a gate valve.
In a preferred embodiment of the present utility model, the pump housing by a tremie pipe and one be flexible coupling with it is described
Rotor weigher top original air inlet is connected.
In a preferred embodiment of the present utility model, the nominal diameter of the bottom airduct is 50mm.
In a preferred embodiment of the present utility model, the bottom of the pump housing is provided with multiple support foot rests.
In a preferred embodiment of the present utility model, the power set are a roots blower.
In a preferred embodiment of the present utility model, the rotor weigher is that Fes spy claims.
Due to using above-mentioned technical proposal, the beneficial effects of the utility model are：The utility model is simple in construction, design is closed
Reason, claims internal air pressure to be less than orlop coal dust material pressure after transformation, gas is no longer played a reversed role to charging aperture so that the air in coal dust contains
Amount greatly reduces, and rate of load condensate is greatly improved, and blanking is smooth, and in the case where equally feeding coal amount, the rotating speed that coal dust claims is substantially reduced,
Or handling capacity is greatly improved in the case of same rotating speed, its attrition value is reduced to the full extent, and extending it makes
With the life-span, greatly reduce maintenance cost and use material cost expense.
