Hot reclaiming equipment for asphalt mixture

Abstract

The invention relates to hot reclaiming equipment for an asphalt mixture. A drying cylinder is mounted on a bracket through a left riding wheel driving device and a right riding wheel driving device; a head with a cavity is fixed at the right end of the drying cylinder, a feed end plate is fixed at the left end of the drying cylinder in a sealing way, the feed end plate communicates with a dust removal device in a sealing way, a feed opening of a raw material conveying device is formed in the feed end plate, and the raw material conveying device is connected with a discharge opening of a raw material hopper; a combustor is arranged at the right end of the drying cylinder and is fixed upside down on the bracket; a partition board and a reclaimed material feed opening are arranged between a combustion zone and a mixing and stirring zone, a discharge opening of a reclaimed material hoist is arranged at the reclaimed material feed opening, an inlet of the reclaimed material hoist is connected with a discharge opening of a reclaimed material conveying device, the reclaimed material conveying device is connected with a reclaimed material hopper, and the reclaimed material hopper is connected with a crushing device through a crushing conveying belt; and a mixture discharge opening is formed in the bottom of the drying cylinder and located at the mixing and stirring zone, and the mixture discharge opening is connected with a vibrating screen through a hot material hoist. The hot reclaiming equipment is small in size, uniform in heating and free from pollution.

Description

technical field [0001] The invention belongs to the technical field of asphalt concrete mixing, and in particular relates to thermal regeneration equipment for asphalt mixture. Background technique [0002] The design life of the existing asphalt pavement is generally 15 to 20 years. Many roads in my country have entered the period of major and medium repairs. The asphalt pavement that needs to be refurbished every year in the country is calculated at 10%. There are more than 50,000 kilometers, and the waste asphalt materials produced every year will exceed 15 million tons. If these huge amounts of waste asphalt are not recycled, it will not only waste resources, but also cause serious pollution to the environment. Therefore, the recovery and recycling of asphalt materials are of great significance to saving maintenance costs and protecting the environment. There are many thermal regeneration equipment in different forms on the market, but the following problems exist in di...

Problems solved by technology

There are many thermal regeneration equipment in different forms on the market, but the following problems exist in different degrees: 1), the equipment is tall, complex and heavy, and requires 80-200 tons of steel to make; 2), the regenerated material inlet and the burner are set on the same side , due to the low heating temperature required for recycled asphalt materials, there may be problems with the aging of recycled asphalt materials or uneven heating; 3), the asphalt fumes generated during the heating process pollute the environment; 4), shorten the use of dust removal system accessories (cloth bags) life
