A high-efficiency drying equipment for cement production

Abstract

A high-efficiency drying equipment for cement production, including a base plate and two end covers fixed on the base plate, a cylindrical drum with open ends is installed in rotation between the two end covers, and a plurality of cylindrical cylinders are arranged inside the drum. Cavities, the diameters of multiple cavities increase sequentially from the feed port to the discharge port. The inner coaxial line of the drum is provided with a hollow shaft with openings at both ends. The push plate assembly includes a hollow shaft fixed on the hollow shaft. The upper baffles of the semi-disc, the lower baffles are installed on multiple upper baffles, each set of upper baffles and lower baffles can form a complete disc and the circle formed by each set of upper baffles and lower baffles The diameter of the disc is the same as the diameter of the cavity in which it sits. It can uninterruptedly dry the cement raw materials without stopping to feed and discharge the cement raw materials, which greatly improves the production efficiency. At the same time, it has a cooling effect and does not need to stop for cooling. Workers are not scalded, and the safety during use is improved.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to a high-efficiency drying equipment for cement production. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. For a long time, it has been used as a An important cementing material, widely used in civil construction, water conservancy, national defense and other projects. In the cement industry, the ball milling process can grind the sintered cement clinker into powder, and then dry the cement through the drying equipment. Cement can be put into use, therefore, drying equipment determines the production efficiency and production quality of cement. Most of the existing cement drying methods are tumble dryers. In the center of the tumble dryer, the addition of a ...

AI Technical Summary

Problems solved by technology

However, although the existing tumble dryer can dry a large amount of cement at a time, it needs to be shut down after each drying, and the internal cement is cooled before discharging. If it is not cooled, it is easy to discharge There is a risk of burns to workers, but the time taken for cooling is long, which leads to the inability to improve the efficiency of the entire production. Continuous production without cement often requires multiple tumble dryers to work interspersed. Increased equipment costs
