Embodiment Construction

[0010] The following is a further description in conjunction with the accompanying drawings. This product is a detachable and washable asphalt nozzle, including a nozzle. The inner tube 2 is composed of two arc-shaped tiles. The two ends of the inner tube 2 of the nozzle are provided with a concave step surface 3, and a fastening ring 4 is sleeved on the concave step surface 3. One of the fastening rings 4 The outer diameter is smaller than the inner diameter of the nozzle outer tube 1; in order to facilitate disassembly and maintenance of the nozzle inner tube by a wrench, the outer surface of the fastening ring 4 is a hexagonal prism.

[0011] In order to improve the stability of the structure of the inner pipe 2 of the nozzle, an annular inner groove is arranged on the inner pipe 2 of the nozzle, and a support ring 5 whose outer diameter is equal to the inner diameter of the inner groove is arranged in the inner groove.

[0012] When the asphalt is not ejected smoothly, the...

Abstract

The invention discloses a detachable-washable type asphalt spraying pipe. The detachable-washable type asphalt spraying pipe comprises a nozzle, wherein the nozzle comprises an inner nozzle pipe and an outer nozzle pipe; the inner nozzle pipe is arranged on the inner wall of the outer nozzle pipe through threads and is formed by combining more than two arc-shaped tiles; concave step surfaces are arranged at two ends of the inner nozzle pipe; each concave step surface is sleeved with a fastening ring; the outer diameter of one of the fastening rings is smaller than the inner diameter of the outer nozzle pipe. During operation of the detachable-washable type asphalt spraying pipe, the inner nozzle pipe which is arranged in the outer nozzle pipe contacts asphalt liquid. When the detachable-washable type asphalt spraying pipe needs to be cleaned, the inner nozzle pipe can be directly disassembled. By disassembling the inner nozzle pipe, the wall of the inner nozzle pipe can be conveniently washed.
