Abstract
The present invention relates to a process and a device for preparing raw cement. The process is characterized in that a drying process in a flow path from a limestone storage yard to a grinding head bin is removed in an original material drying process; a drying machine is arranged in front of a ball mill, namely that the drying process exists when material passes from the grinding head bin to the ball mill. The present invention is characterized in that drying in front of a storing house is changed into grinding head drying and has the advantages of 70% of power saving, 50% of coal saving, man and material saving, environmental pollution reduction, change of mill work condition and enhancement of ball mill yield.
Description
The present invention relates to cement slurry preparation technology and equipment.
Cement production process has strict requirement to the water content of ball mill mill feed material, all there is independently drying materials system in most of producers, mill feed material is gone into mill by being transported to after the oven dry after the storage storehouse reenters the bistrique storehouse and prepares burden one by one, and its typical preparation were established is 2: the 1st, Wingdale is prepared burden into ball mill to bank to bistrique storehouse to bank to drying machine drying through crusher in crushing again; The 2nd, clay, coal, iron powder drying machine are dried to bank and are prepared burden into ball mill to the bistrique storehouse, and Fig. 1 is seen in technical process.
It is more that this technology is adapted to silt content, the production of the Wingdale that moisture content is heavier, but have following drawback:
1, to have bad luck process many for material, and mechanical means is many, and investment is big, the cost height; 2, it is serious that material is had bad luck in the process environmental pollution; 3, depositing in the bank process heat behind the drying materials in scatters and disappears and causes waste.
The objective of the invention is to overcome the shortcoming of existing stoving process, propose a kind of cement slurry and prepare bistrique oven dry novel process and bistrique dryer for realizing that novel process designs.
Technical scheme of the present invention is: the stoving process from the flow process of Wingdale stockyard to bistrique storehouse in the former material stoving process is removed, a dryer is set in the ball mill front, be that material has stoving process from the bistrique storehouse between the ball mill, its technical process is: Wingdale through crusher to bank to the bistrique storehouse to the bistrique dryer to ball mill; Clay, coal and iron powder drying machine to bank to the bistrique storehouse to the bistrique dryer to ball mill.
For realizing above-mentioned bistrique stoving process, the present invention has designed a bistrique dryer.The structure of its bistrique dryer is: it is by lock wind hopper 1, dram 2, aligning hopper 3 three parts are formed, dram is between lock wind hopper and aligning hopper, one end of lock wind hopper is connected with the flue flange, the other end inserts in the centre hole of dram feed end, the top of lock wind hopper is provided with hopper 4, the discharge end of dram inserts the feed port of aligning hopper, the discharge nozzle of aligning hopper inserts the quill shaft of ball mill, the top of aligning hopper is provided with the meal inlet, be connected with powder separating machine powder retrieving pipe flange, lock wind hopper and aligning hopper are fixed on the basis, ground with supporting leg; Dram adopts the supporting of backing ring support roller, and backing ring is fixed on the cylindrical shell, and support roller is fixed on the basis, ground by the support roller seat; Dram is passed through reduction box, pinion(gear), master wheel driven rotary by motor.
Be delivered to lock wind hopper through deployed cement material by belt and enter dram from hopper, hot blast enters dram through the heating duct of lock wind hopper, and material rolls in dram and advances, and oven dry enters ball mill through the aligning hopper then while advancing.
Because the present invention adopts bistrique oven dry novel process and bistrique drying plant, has following positive effect.
1, energy-conservation.Because the hot gas and the thermal material of dryer directly enter ball mill, have reduced the thermosteresis in the former technical process, have relaxed the requirement to material moisture, improved the starting temperature point of evaporation moisture content, increased velocity of evaporation, can economize on coal 50% than old technology.Novel process is had bad luck process mechanism power consumption in the middle of simplifying, having saved, and can economize on electricity 70%.
2, reduced environmental pollution.Former process stream is had bad luck a large amount of dust of generation in the process in oven dry, is difficult to collect, and the material that novel process is transported is moist, and dust obviously reduces.
3, the ball mill working condition is improved, and output improves.Because the mill feed material increase in temperature, the flue gas of dryer is further passed to material in mill, increased water evaporates speed, and full mill and paste ball phenomenon are difficult for taking place, and mill output is improved, and platform produces can increase by 16%.
4, expenses such as manpower consumption and site facility have been saved.Novel process has reduced has bad luck the link of gathering dust, thereby has reduced operator.Because limestone material need not a large amount of storages, so saved expenses such as place and facility.
