Screening device used for cement production

Abstract

The invention discloses a screening device used for cement production. The screening device is reasonable and simple in structure, low in production cost, convenient to install, complete in function,thorough in filtering effect, low in screening noise, convenient to operate and high in production efficiency. Cement is input through a feeding nozzle. A first motor drives a feeding shaft to transport the cement and disengage the cement into a stirring chamber from a discharging pipe. In the transporting process, a permanent magnet adsorbs metal impurities in the cement, the cement is located inthe stirring chamber, a second motor drives a rotating shaft to rotate, and a first stirring rod and a second stirring rod are used for stirring the cement and sufficiently scattering the solidifiedcement. Then the cement enters a filtering net of a screening chamber, a third motor drives a cam to rotate, the cam is used for knocking an L-shaped supporting rod, and therefore the cement is filtered. Meanwhile, a fourth motor drives an induced draught fan to rotate to extract the cement in the air, and the cement is stored in a cement collecting chamber. By means of the above technical scheme,the problems in the background technology are sufficiently solved.

Description

Technical field: [0001] The invention relates to the technical field of cement production, in particular to a screening device for cement production. Background technique: [0002] The finished cement of cement production enterprises is generally stored in the cement warehouse for several days before leaving the factory to ensure the stability of the cement and further reduce the temperature of the cement. The climate in the coastal area is humid. Due to the characteristics of the cement itself, the tiny water molecules in the cement will automatically absorb and condense to form small cement ash. The moisture will absorb on the wall of the storehouse, and the cement will also form crusts and agglomerates to a certain thickness. The cement ash and crust agglomerate are mixed in the cement, which not only affects the quality of the cement, but also blocks the ash discharge pipe after being loaded into the tanker, causing the cement in the tanker to not be pumped out. Therefo...
