Granulating and drying device of cement blocks

Abstract

The invention discloses a granulating and drying device of cement blocks. The granulating and drying device comprises a grinding chamber, grinding bases, a transmission shaft, a first motor, an electromagnetic valve, a spray connecting pipe, a spray drying chamber, an air heater, an air pressurization pump, a circular table, a first filter screen, a stirring rod, a stirring blade, a second motor, a second filter screen, a safety valve, a spray pipe and a bracket, wherein the stirring rod, the stirring blade and the second motor are utilized to stir cement slurry in the spray connecting pipe, and cement slurry is prevented from accommodating in the spray connecting pipe; the first filter screen is utilized to filter cement slurry, and the situation that cement quality is affected due to the fact that cement particles which do not reach the fineness requirement flow out is avoided; and the second filter screen is utilized to prevent the cement particles from being discharged, the environment is prevented from being polluted, and resources are prevented from being wasted. According to the granulating and drying device, operation is simple, safety performance is high, the cement blocks can be ground and smashed effectively and can be directly dried and granulated, drying and granulating time is short, speed is high, and production efficiency of the cement particles is improved.

Description

technical field [0001] The invention relates to the field of cement manufacturing equipment, in particular to a cement block granulation and drying device. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. Using it to cement concrete made of crushed stones not only has higher strength after hardening , but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. [0003] However, in the cement preparation process, the process of preparing dry cement powder from cement blocks is relatively complicated. The equipment used on the market is to separate cement crushing and cement drying. This method not only reduces production efficien...
