Powder silo and concrete preparation equipment

Abstract

The invention aims to provide a powder warehouse reducing cost and concrete preparation equipment. The powder warehouse comprises a plurality of powder rooms, a dust collecting device and a dedusting device, wherein the dust collecting device is communicated with the powder rooms through a plurality of dust collecting pipelines respectively in a one-way mode, and the dedusting device is connected with the dust collecting device through a dedusting pipeline. A large amount of high-pressure gas, generated when feeding is carried out through all the powder rooms, with dust is collected into the dust collecting device through the dust collecting pipelines and is conveyed into the dedusting device through the dedusting pipeline to be dedusted and filtered. Because the dust collecting pipelines are communicated with the powder rooms in a one-way mode respectively, powder mixing caused by parallel connection of the dust collecting pipelines of the powder rooms storing different kinds of powder is avoided, and accordingly requirements for carrying out dedusting among the powder rooms can be met through only one dedusting device; in addition, the number of the dedusting pipeline stretching out of the tops of the powder rooms to a working surface is only one, and therefore cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of concrete mixing, in particular to a powder silo and concrete preparation equipment. Background technique [0002] Commodity concrete and asphalt concrete have been widely used in the construction industry in recent years. Their preparation overcomes the dust and noise pollution caused by traditional on-site mixing. Especially, some large-scale mixing plant manufacturers with high technological content pay more attention to environmental protection issues, so At the sites of these large-scale mixing plants, the material transmission of the powder bin is powered by high-pressure air. During the transportation process, a large amount of dust will be formed in the bin, and the pressure will be greater than the atmospheric pressure. In order to prevent the dust from polluting the environment, And if the pressure is too high and the warehouse bursts, the powder warehouse is equipped with a dust removal device. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] The dust collector is installed on the top of the traditional powder room. It is inconvenient to climb to the roof of the warehouse with a height of more than 20 meters for daily maintenance. However, if the dust collector on the roof of the warehouse is not maintained in time, it will easily cause too much dust to be adsorbed on the filter element in the dust collector, which will affect the dust removal. The dust removal efficiency of the machine

What's more, due to the blockage of the filter element, the high-pressure gas at the top of the powder room cannot be discharged in time, and there are dangerous situations such as ash from the top of the warehouse or the dust collector being lifted by the high-pressure gas.

In the prior art, the dust collector is also installed on the ground and connected to the roof of the warehouse through the dust removal pipe. Then, due to the independence of each set of dust removal pipes, multiple sets of dust removal pipes need to be arranged, which increases the higher cost.
