Asphalt mixing plant

Abstract

The invention provides an asphalt mixing plant. The asphalt mixing plant comprises a charging device, a drying device, a mixing device and a finished product warehouse which are in sequential communication, wherein the drying device comprises a cold aggregate elevator, a sealing drying tower and a hot aggregate elevator which are in sequential communication; the cold aggregate elevator communicates with a discharge opening of the charging device, and a discharge opening of the hot aggregate elevator communicates with a feed opening of the mixing device; the sealing drying tower is arranged between the cold aggregate elevator and the hot aggregate elevator, so that in the drying process, dust and smoke can be effectively prevented from overflowing, the pollution of the dust and flue gas is eliminated, the requirement for environmental protection in the production process is met, and the environmental protection performance in the production process is improved.

Description

technical field [0001] The invention relates to the field of construction machinery, and more specifically, to an asphalt mixing plant. Background technique [0002] The asphalt mixing plant is a production equipment for producing asphalt finished materials. A large amount of dust will be generated during the production of finished materials. Although the dust removal system of the asphalt mixing plant can recover and discharge part of the dust, there is still some dust Directly enter the atmosphere, causing pollution. Among them, the production process mainly includes the feeding process, conveying process, drying process, mixing process, unloading process, loading process, etc. [0003] At present, for the drying process, most of the existing asphalt plant manufacturers mainly heat and dry the cold material by means of drum heating. However, due to the poor airtightness of the drum, it will In the process, a large amount of dust and flue gas overflow, causing dust and flu...

Problems solved by technology

[0003] At present, for the drying process, most of the existing asphalt station manufacturers mainly heat and dry the cold material by means of drum heating. However, due to the poor airtightness of the drum, it will In the process, a large amount of dust and flue gas overflow, resulting in dust and flue gas pollution, which seriously reduces the environmental protection of the production process, making the production process unable to meet the environmental protection requirements
