Water-cooled wall horizontal type cement cooling device with built-in spring

Abstract

The invention discloses a water-cooled wall horizontal type cement cooling device with a built-in spring. The water-cooled wall horizontal type cement cooling device comprises a support for installation and a barrel installed on the support. A hollow shaft is arranged in the barrel, and one end of the hollow shaft is connected with a speed reducer and a motor so as to drive the hollow shaft to rotate; a spiral blade and a material raising blade are welded on the periphery of the hollow shaft; and a water cooling wall for cooling materials in the barrel is arranged on the peripheral surface of the lower part of the barrel. The heat exchange manner of the water cooling wall is adopted, the heat exchange effect is enhanced through the material raising blade and springs in brass thin-wall square pipes in an auxiliary manner, and high-temperature ground cement can be rapidly cooled to the needed temperature.

Description

technical field [0001] The invention belongs to the technical field of cooling devices in the building materials and chemical industries, and in particular relates to a water-cooled wall horizontal cement cooling device with a built-in spring. Background technique [0002] With the rapid development of infrastructure construction, the construction sites of some important projects, such as airport runways, nuclear power plants, dam bridges, etc., have mandatory requirements for the use temperature of cement, which is generally lower than 60 °C. However, the grinding process of cement production leads to the cement grinding temperature generally above 100°C. Excessively high temperature is the main cause of storage condensation and dehydration of gypsum, which in turn affects the quality of concrete and construction performance. Therefore, through the cooling process, the control of cement temperature has become one of the important indicators to measure the quality of cement....

AI Technical Summary

Problems solved by technology

The unit energy consumption of the spiral lift cooler is high, the operating efficiency is low, the equipment is large, and the external circulating water is used, which has high requirements for the user's production site and process layout. The water vapor is directly discharged, which is not conducive to water saving and environmental protection.

Water spraying in the mill is a direct heat exchange cooling method with high heat exchange efficiency, but the nozzle and other components are easy to block, the reliability of the water spray system is poor, and even lead to production accidents

At the same time, too much water spray will affect the quality of cement, and too small water spray will affect the cooling effect, so it is necessary to accurately control the water spray

Based on the above reasons, the actual popularization and application effect of the above two cement cooling devices is not ideal
