Cement storage bin

Abstract

The invention relates to the technical field of concrete production equipment, in particular to a cement storage bin. The cement storage bin comprises a bin body and dust removal equipment arranged atthe top end of the interior of the bin body, a material receiving pipe is arranged at the top end of the bin body in a penetrating mode, the end, located inside the bin body, of the material receiving pipe communicates with a material guiding pipe, the bottom end of the material guiding pipe is located at the bottom in the bin body, the bottom end of the material guiding pipe is closed, the sidewall of the material guiding pipe communicates with a plurality of material distribution pipes from top to bottom, each material distribution pipe is provided with a one-way valve, and the opening pressure of the one-way valves arranged from top to bottom is gradually reduced. According to the cement storage bin, the effects of reducing flying dust in the storage bin, reducing the working intensity of dust removal equipment and improving the safety and environment friendliness of the storage bin are achieved.

Description

technical field [0001] The invention relates to the technical field of concrete production equipment, in particular to a cement storage bin. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . With the continuous development of infrastructure in recent years and the sustained and rapid development of the national economy, a large number of old buildings have been demolished, and a large amount of waste concrete has been generated. After crushing, cleaning and grading waste concrete blocks, they are mixed in a certain proportion. The new concrete formed by forming recycled aggregate and adding cement, water, etc. is called recycled concrete. [0003] Both ordinary concrete and recycled concrete need to use a large amount of ceme...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned existing technical solutions have the following defects: when the cement transport vehicle feeds the material to the storage silo, it is generally a long-term continuous process. When the dry cement powder falls freely from the top of the storage silo to the bottom of the storage silo, There is a large height difference, which causes more cement to be filled in the storage bin in the state of floating matter. When the excess air is discharged from the storage bin, it will carry a large amount of cement dry powder, thereby increasing the working strength of the filter element, which is very It is easy to cause blockage or even damage to the filter element, which will lead to serious situations such as leakage of cement dry powder and pollution of the environment. More serious cases may lead to the explosion of the storage bin, and the excess air in the storage bin is discharged from the bottom to the top. As a result, there is an upward force on the dry cement powder filtered outside the filter element, and it is difficult to remove the dry cement powder on the filter element during the pulse blowback of the dust collector during transportation. In the long run, it will also cause blockage and damage to the dust removal equipment.
