Problems solved by technology

The first three methods are simple, but the cooling effect is limited
The fourth method, spraying water in the cement mill, the effect is better than the first three, but it is difficult to completely solve the problem of clogging of the small holes of the nozzle
The fifth method, cooling with a spiral lift cooler, is better than the first four methods, but this kind of equipment requires high processing and manufacturing technology, large investment, high operating cost, poor adaptability to process conditions, and the effect of popularization and application is not ideal.

Abstract

The invention discloses a horizontal spiral cement cooler, which comprises a support. A horizontal barrel is arranged on the support; a hollow shaft is rotatably arranged in the barrel; a hollow spiral blade which is communicated with the hollow shaft is arranged on an outer circumferential surface of the hollow shaft; a plurality of spray pipes are arranged above the barrel; and a cooling water tank capable of soaking the barrel is arranged under the barrel. The horizontal spiral cement cooler has the advantages of simple structure, reliable operation, good cooling effect, simple and convenient maintenance and operation, low operation and manufacturing cost, and the like, and can be used for cooling powdery high-temperature materials in various industries.

Description

Technical field: [0001] The invention mainly relates to a cooling device, in particular to a horizontal spiral cement cooler. Background technique: [0002] With the development and progress of society, the speed and quality of engineering construction have been continuously improved. More and more construction projects have put forward strict requirements on cement quality, especially the requirements on cement temperature, such as tunnels, reservoir dams, roads and bridges, and submarine projects. Equivalence requires that the temperature of the cement be lower than 70°C. Because the temperature of cement is too high, it will not only lead to dehydration of gypsum, affect the quality of cement, but also affect the progress of engineering construction and the quality of concrete construction. [0003] However, most of the heat generated during the grinding process of cement production is absorbed by the cement, resulting in the temperature of the cement being ground genera...
