Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the burner 12 sprays fire and dries from one end of the discharge port 13 to the drying cylinder 1, and when the exhaust pipe 14 performs exhaust and dust removal on the discharge port 13, the combustion Part of the hot air heated by the device 12 will be sucked away by the exhaust pipe 14, resulting in heat loss and making the drying efficiency of the dryer lower

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] like figure 2 , is a recycled aggregate dryer with dust removal function disclosed in the present invention, comprising a drying cylinder 1, one end of the drying cylinder 1 is fixedly connected with a feeding hopper 11, and one end of the drying cylinder 1 is far away from the feeding hopper 11 A burner 12 is provided, and the burner 12 extends into the interior of the drying cylinder 1 through the end surface of the drying cylinder 1 and sprays fire toward the interior of the drying cylinder 1, so as to heat and dry the recycled aggregate inside the drying cylinder 1. One end of the drying cylinder 1 provided with a burner 12 is fixedly connected with a square discharge pipe 2 . The end of the discharge pipe 2 away from the drying cylinder 1 is bent vertically downward, and since the hot gas floats upward, the occurrence of the heat generated by th...

Abstract

The invention discloses a recycled aggregate dryer with a dust removal function, and relates to the technical field of recycled aggregate drying devices. The recycled aggregate dryer comprises a drying cylinder. A combustor is arranged at one end of the drying barrel. A discharge pipe is arranged at the end, provided with the combustor, of the drying cylinder. One side face of the discharge pipe is connected with an air blower and is further connected with a dust remover. The problem that due to the fact that when air exhausting dust removal is conducted on the position of a discharge port through an air exhausting pipe, a part of hot gas heated by the combustor can be exhausted by the air exhausting pipe, loss of heat is caused and the drying efficiency of the dryer is made to be low is solved. The recycled aggregate dryer has the effects that dust removal during discharging of the dryer is facilitated, the heat loss is reduced and the drying efficiency is high.

Description

technical field [0001] The invention relates to the technical field of recycled aggregate drying equipment, in particular to a recycled aggregate dryer with dust removal function. Background technique [0002] Asphalt mixture is a mixture made by mixing mineral materials and asphalt binder. Aggregate is mainly divided into primary aggregate and recycled aggregate. Recycled aggregate refers to recycled materials from waste asphalt pavement. Both primary aggregate and recycled aggregate need to be dried by drying equipment, especially after the recycled aggregate is dried, because the recycled aggregate is relatively fragile and easy to pulverize, a large amount of dust is prone to appear during the discharging process. [0003] like figure 1 , the existing recycled aggregate dryer includes a drying cylinder 1, one end of the drying cylinder 1 is provided with a feed hopper 11, and the other end is provided with a discharge port 13. One end of the drying cylinder 1 provided ...
