Water-preadding balling process and equipment for cement clinker calcining kilns

Abstract

The invention provides a water-preadding balling process and equipment for cement clinker calcining kilns. The equipment is characterized in that a raw material bin, a steady-flow control reamer and a raw material-metering bin are connected in series; the raw material-metering bin and a water quantity-metering bin are communicated with a material-throwing type stirrer through water pipes respectively; the material-throwing type stirrer is connected with a wet material bin; a yield control speed-regulating belt is connected with a balling disc; the balling disc is connected with a conveyor belt A; the conveyor belt A is connected with a rolling sieve; the rolling sieve is connected with a conveyor belt B; and the conveyor belt B is connected with the balling disc. The invention has the advantages that the process and the equipment can reduce the discharge amount of smoke and dust by over 90 percent because balling quality is greatly promoted, can greatly reduce the operation load of environment-protecting dust-collecting systems, and realize the strong-wind light / dark fire continuous calcination of big / small-material balls, so that the great comprehensive potential of cement clinker calcining kiln processes is thoroughly released; in addition, the balling process is little in investment in technical transformation, quick in response, easy to implement and popularize in cement clinker calcining kiln enterprises and remarkable in social and economic benefit.

Description

technical field [0001] The invention relates to a novel cement clinker calcining kiln pre-adding water into pellets process and equipment thereof, belonging to the technical field of cement building materials. Background technique [0002] The process of pre-adding water into balls is one of the most critical links in the cement clinker kiln. Once the quality of the balls is stable, the whole cement clinker kiln will have problems such as batching, air use, unloading, raw ash fineness, dust collection and environmental protection. With a reliable operation verification platform, each element can be individually adjusted to the best condition, which greatly simplifies the original seemingly complicated firing production and quality problems, and realizes continuous sintering with strong wind, large material and small material ball, shallow and dark fire . The core essence of kiln cement clinker production is the accurate quantitative continuous chemical combustion reaction p...

AI Technical Summary

Problems solved by technology

The core essence of kiln cement clinker production is the accurate quantitative continuous chemical combustion reaction process. If the measurement control in the ball forming process is not accurate and unstable, it is easy to cause uneven distribution or blockage of the outer and inner pores of the kiln fired belt balls, which will It will greatly affect the balanced supply of oxygen ventilation required for the oxidative combustion reaction in the firing zone, and it is easy to produce bad kiln conditions such as smelting, agglomeration, wind tunnel, partial fire, overhead and even spray kiln, which will not only seriously damage product quality and output, but also It will lead to the waste and loss of a large amount of raw materials, fuels and electric energy, and at the same time damage the environment and increase the workload of kiln workers.
