Abstract
The utility model discloses a system for externally blending coal powder to milled cement. The system comprises a coal powder tank, a spiral feeder and a spiral dosing scale; the discharging port of the coal powder tank is connected with the feeding port of the spiral feeder, the feeding port of the spiral dosing scale is connected with the discharging port of the spiral feeder, a coal powder tank support is arranged at the lower part of the coal powder tank, a spiral feeder support is arranged at the lower part of the spiral feeder, and the lower part of the spiral dosing scale is arranged on the spiral feeder support by a support bar. The system for externally blending the coal powder to the milled cement is arranged at the exterior of a milled hoister of a cement mill, the discharging port of the spiral dosing scale is connected with a discharging chute arranged at the lower part of the milled cement hoister, so after weighing by the spiral dosing scale, the coal powder can be added to the milled cement system by the spiral feeder, therefore, both technical requirements and operating requirements on cement can be met in the condition of saving investment.
Description
Technical field
The utility model belongs to the technology of producing cement field, particularly a kind ofly goes out to grind the outer fly ash system of cement.
Background technology
Cement grinding is the finishing operation that cement is made, and also is the maximum operation of power consumption.Its major function is cement clinker (reaching retardant, performance adjustment material etc.) grinding to suitable granularity (with expressions such as fineness, specific surface areas), form certain grain composition, increase its aquation area, quicken hydration rate, satisfy cement slurry and condense, the sclerosis requirement.Produce high performance cement, improve workability and the suitability of cement in construction, improve competitive power and the occupation rate of product in market.By doing experiment in the laboratory, go out to grind mix flyash in the cement after, can improve and improve cement performance, reduce water requirement, and the flyash that is mixed does not need to carry out grinding.And at present, a lot of manufacture of cement producers do not have the equipment of outer fly ash in the cement ingredient system, and this carries out cement grinding process with regard to still needing to expend a large amount of electric energy, and this has also increased production cost virtually, has reduced the productivity effect of enterprise.
The utility model content
The utility model is in order to solve weak point of the prior art, provides a kind of and goes out to grind fly ash system outside the cement to what go out to grind to mix in the cement flyash.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: go out to grind the outer fly ash system of cement, comprise flyash silo, screw feeder and spiral metering scale, the discharge port of flyash silo is connected with the opening for feed of screw feeder, and the opening for feed of spiral metering scale is connected with the discharge port of screw feeder.
Described flyash silo bottom is provided with the flyash silo support, and the screw feeder bottom is provided with the screw feed machine support, and the spiral metering scale bottom is located on the screw feed machine support by pole.
Adopt technique scheme, utilize existing cement ingredient system, the utility model is located at cement and grinds the lift outside, the discharge port of spiral metering scale goes out to grind lift bottom blanking groove with cement and is connected, like this can be with flyash by screw feeder and through joining cement and go out in the grinding system by going out to grind lift after the weighing of spiral metering scale, under the situation of reducing investment outlay, satisfy processing requirement, guarantee to satisfy the service requirements of cement simultaneously.Because the required power consumption of cement grinding accounts for 40% of manufacture of cement power consumption, therefore, the utlity model has good economic benefits, institute adds flyash does not need grinding, fully reduce power consumption, made the cement grinding power consumption reach advanced level, increased economic benefit of enterprises greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, of the present utility modelly go out to grind the outer fly ash system of cement, comprise flyash silo 1, screw feeder 2 and spiral metering scale 3, the discharge port 4 of flyash silo 1 is connected with the opening for feed 5 of screw feeder 2, and the opening for feed 6 of spiral metering scale 3 is connected with the discharge port 7 of screw feeder 2.Flyash silo 1 bottom is provided with flyash silo support 8, and screw feeder 2 bottoms are provided with screw feed machine support 9, and spiral metering scale 3 bottoms are located on the screw feed machine support 9 by pole 10.Wherein screw feeder 2 and spiral metering scale 3 are prior art, and concrete structure repeats no more.
During use, the flyash that stores in flyash silo 1 is by the conveying of screw feeder 2 and the weighing of spiral metering scale 3, the discharge port 11 of spiral metering scale 3 goes out to grind lift 12 bottom blanking grooves 13 with cement and is connected, and flyash joins in the cement ingredient system by going out to grind lift 12.Go out to grind mix flyash in the cement after, improved cement performance, reduce water requirement, improve workability and the suitability of cement in construction, improve competitive power and the occupation rate of product in market.
