7th, this utility model is provided with two high inclination-angle drag conveyors, can further carbide slag be dried, this
Conveyor construction is simple, reliable, easy to maintenance, more can high inclination-angle convey, compact conformation, floor space is few.
Brief description
Fig. 1 is the structural representation of this utility model recycling system；
In figure label：1 primary sedimentation basin；1a stock inlet；2 secondary sedimentation tanks；3 concentration basins；4 slurry storehouses；5 board-like filter pressings
Machine；5a gas hole；6 high inclination-angle drag conveyors；7 enter to grind belt；8 Pulp pump.
Specific embodiment
As shown in figure 1, the recycling system of industrial waste carbide slag, including passing sequentially through the one of Pulp pump 8 connection
Secondary sedimentation tank 1, secondary sedimentation tank 2, concentration basin 3, slurry storehouse 4 and plate type pressure filter 5；Plate type pressure filter 5 is defeated through high inclination-angle scraper plate
Send machine 6 to connect and enter to grind belt 7 to raw material vertical-grinding.
Stock inlet 1a is provided with primary sedimentation basin 1.
The stock inlet side of plate type pressure filter 5 is provided with gas hole 5a.
High inclination-angle drag conveyor 6 totally two, First is arranged at the blanking of plate type pressure filter 5, and second is arranged on
First and enter to grind between belt 7.
Using the recoverying and utilizing method of the industrial waste carbide slag of above-mentioned recycling system, comprise the steps：
(1) precipitate
Carbide slag slurries introducing primary sedimentation basin is carried out primary sedimentation process, then again secondary precipitation is squeezed into by Pulp pump
Pond carries out secondary precipitation process (Ca (OH)2Particulate deposits are got off), form carbide slag slurries after precipitation；The clear liquid of secondary sedimentation tank overflows
Flow into collecting-tank；Facts have proved the technological requirement meeting the reaction of carbide in acetylene generator through the clear liquid of secondary precipitation, can be by
It is used for so that water resource is recycled in the acetylene production with carbide as raw material, saving water resource.
(2) concentrate
After precipitation, carbide slag slurries squeeze into concentration basin through Pulp pump, carry out concentration, form carbide slag slurries after concentrating；Concentrate
Carbide slag slurries squeeze into slurry storehouse through Pulp pump afterwards；After concentration, the water content of carbide slag slurries is 65%～70%.
(3) filter pressing
After the concentration in slurry storehouse, carbide slag slurries are squeezed in plate type pressure filter through Pulp pump, in carbide slag slurries after concentration
Moisture content is discharged after filter-cloth filtering further, and carbide slag slurries moisture is less and less, is gradually shaped to pie between sheet frame；For solving
Fracture and whitewashing problem that plate type pressure filter discharging does not totally cause, at the end of pressure filter work just, using pressure-air
Carbide slag in board-like filter pressing is blown, so that carbide slag slurries are dehydrated further, obtains a carbide blob of slag；The containing of a carbide blob of slag
The water yield is 30%～40%.
(4) grinding, drying
A carbide blob of slag is transported to entering of raw material vertical-grinding through high inclination-angle drag conveyor after metering and grinds on belt, and for water
Other raw materials (limestone, iron powder, clay) that mud produces enter raw material vertical-grinding together and carry out grinding, drying, obtain cement slurry；
The metering of a carbide blob of slag is controlled by the operating frequency of plate type pressure filter, that is, pass through drawing of plate pulling trolley of filter press
The conveying capacity of plate speed controlling carbide slag charge cake, reaches the effect of raw meal proportioning.
Drying is to be completed by the waste gas of 180～220 DEG C sending from kiln tail, reduces the water consumption of raw material vertical-grinding.
(5) calcine
Enter new dry process nsp kiln after the metering of cement slurry homogenized storehouse to be calcined, obtain clinker.
Drag conveyor has certain inclination angle, and the carbide slag moisture of entrance raw material vertical-grinding can be made to reduce further.
Grinding, drying are carried out together, it is possible to reduce energy consumption, cost-effective, reduce equipment usage amount, simplify carbide slag
Drying process.
The cement consumption per ton coal 88kg being produced using recycling system of the present utility model, three days pressure resistances of clinker
Degree reaches 30Mpa.
