Method.
Background technique
Clinker needs grinding to accelerate the water of cement to increase the water accessible area of cement products to suitable granularity
Change speed, to meet the rate requirement of cement slurry condensation, hardening when in use.Clinker powder in the prior art point
Screening device and clinker milling device are two devices being independently arranged, and first pass through clinker milling device for clinker
Particle is clayed into power, and is then sent to the clinker powder sorting unit and is carried out pneumatic separating, partial size is biggish after sorting
Clinker powder is transmitted back to clinker milling device again and is milled.Above-mentioned technique makes equipment overall structure complicated and work
It is lower to make efficiency, energy consumption is higher.
Further, since the partial size of the clinker powder sufficiently after grinding is smaller, conventional pocket type dust-collecting equipment dust is received
It is lower to collect efficiency, and is easy to appear the problem of clinker powder is across dust bag or blocking dust bag mesh, therefore mostly
Clinker powder is collected using electrostatic precipitation equipment, but there are the higher problems of energy consumption for electrostatic precipitation equipment；Therefore have
Necessity designs a kind of finished ground cement dust side of the low energy consumption advantage of efficient and pocket type dust-collecting equipment for having both electrostatic precipitation equipment
Method.
Summary of the invention
It for overcome the deficiencies in the prior art, can be in powder the present invention provides a kind of clinker separation and collection method
It is sorted while grinding operation, and powder collecting mechanism had not only had the advantages that electrostatic precipitation equipment high efficiency, but also had pocket type collection
The advantages of dirt equipment low energy consumption.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of clinker separation and collection method, includes the following steps：
Step 1: the roller ball mill equipment that short grained clinker is delivered to axis horizontal setting is located at the upper of axial one end
You Duanzhong makes short grained clinker to movement in the middle part of roller ball mill equipment by air blast；
Step 2: the outer roller of roller ball mill equipment is persistently rotated around horizontal axis, the milling spin of roller ball mill equipment exists
It is rolled in the outer roller of roller ball mill equipment and grinding is carried out to short grained clinker；
Step 3: being acted on by wind-force will from the upstream end of roller ball mill equipment to the downstream air blast for being located at the axial other end
The lesser clinker powder of partial size is blowed to the downstream of roller ball mill equipment；
Step 4: the clinker powder that roller ball mill device downstream end exports is delivered in electrostatic precipitation equipment, and cement
Discharge process of the clinker powder before entering electrostatic precipitation equipment through discharge electrode carries negative electrical charge；
Step 5: after clinker powder enters electrostatic precipitation equipment, with collecting electrode positively charged in electrostatic precipitation equipment
Plate comes into full contact with and is adsorbed in collecting electrode plate；
Step 6: tapping collecting electrode plate, makes the clinker shed powder adsorbed in collecting electrode plate and be collected.
As a further improvement of the above technical scheme, in step 1 and step 2, the outer roller of roller ball mill equipment
For spindle-type α-Fe2O3.
As a further improvement of the above technical scheme, in step 4, by the downstream of roller ball mill equipment to
Clinker powder is delivered in the electrostatic precipitation equipment being located above by upper air blast.
As a further improvement of the above technical scheme, in step 5, multiple dusts are provided in electrostatic precipitation equipment
Electrode plate, the hollow out ventilation hole of several matrix arrangements is provided in each collecting electrode plate, and air-flow drives clinker powder
It sequentially passes through muti-piece to be parallel to each other and perpendicular to the collecting electrode plate in air motion direction, finally makes the clinker powder in air-flow
Last to be all adsorbed in collecting electrode plate, then electrostatic precipitation equipment is discharged in dust-free air.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of clinker separation and collection method provided by the present invention, by carrying out lasting drum in roller ball mill equipment
Wind can be sorted while grinding operation, not only simplify the structure of equipment, but also work efficiency is high, low energy consumption.
In addition, having the collecting electrode plate of several hollow out ventilation holes by setting, one side hollow out ventilation hole can be penetrated
Air and stop dust, another aspect collecting electrode plate can carry out Electrostatic Absorption to dust, both have electrostatic precipitation equipment high
The advantages of effect, and have the advantages that pocket type dust-collecting equipment low energy consumption.
