Dust recycling system of asphalt stirring cylinder

Abstract

The invention discloses a dust recycling system of an asphalt stirring cylinder. The dust recycling system comprises a dust collector, an air separation chamber, an air supply system and a powder processing chamber. A first branch pipe is communicated with the dust collector, a second branch pipe is communicated with a smoke exhaust port of the stirring cylinder, the first branch pipe and the second branch pipe are communicated with a main pipe, the main pipe is communicated with the air separation chamber, a draught fan is provided with an air inlet and an air outlet, and an air draft pipe is communicated with the air separation chamber and the air inlet; the dust processing chamber includes a first body, a water inlet is formed in the upper end of the side wall of the first body, a first feed inlet is formed in the lower end of the side wall of the first body, a discharge pipe is communicated with the air outlet and the first feed inlet, an exhaust port is formed in the center of an upper cover of the first body, the diameter of the lower end of the upper cover of the first body is reduced to a first discharge opening, the water inlet and the first discharge opening are provided with electromagnetic valves, and the air separation chamber, the draught fan and the electromagnetic valves are electrically connected with a controller. The system has the advantages that fine aggregate is efficiently used, smoke is filtered so that air pollution caused by harmful gas and dust can be reduced, and powder blocks are convenient to convey.

Description

technical field [0001] The invention relates to the field of asphalt concrete mixing equipment, in particular to a dust recovery system of an asphalt mixing tank. Background technique [0002] A large amount of dust will be generated during the working process of the asphalt mixing plant. In order to reduce the pollution of dust to the environment and recycle the dust, the asphalt mixing plant is equipped with a dust recycling system. There are several problems in the existing dust recovery system: first, the flue gas is directly discharged into the atmosphere and pollutes the environment; second, the dust is not fully utilized, and the large particle size and dust in the flue gas are directly returned to the powder bin, resulting in a large waste; Third, the dry dust is directly stored in the powder bin, which is inconvenient for recycling; fourth, the equipment is bulky, complex in structure, and takes up a lot of space. Contents of the invention [0003] In order to so...
