Double-loop sound barrier production line

Abstract

The invention belongs to the technical field of a sound barrier and discloses a double-loop sound barrier production line. The double-loop sound barrier production line comprises a heavy part loop anda light part loop; the heavy part loop and the light part loop share the same powder solidification furnace; the heavy part loop consists of a first part feeding device, a sand blasting device, a spraying device, a water washing device, a drying device, a first spray-coating device, the powder solidification furnace and a first part discharging device which are sequentially connected through a heavy part hanging chain to form a closed-loop type spray-coating production line connected end to end; the light part loop consists of a second part feeding device, a second spray-coating device, the powder solidification furnace and a second part discharging device which are sequentially connected through a light part hanging chain to form a closed-loop type spray-coating production line connectedend to end; the heavy part hanging chain and the light part hanging chain are both in inflected U-shaped distribution inside the powder solidification furnace; and the parts, inside the powder solidification furnace, of the heavy part hanging chain and the light part hanging chain are arranged in parallel with each other. The double-loop sound barrier production line provided by the invention isingenious in conception, simple and convenient to operate and capable of solving the technical problems that the sound barrier in the prior art is large in floor area and high in energy consumption.

Description

Technical field [0001] The invention belongs to the technical field of sound barriers, and relates to a double-loop line sound barrier production line. Background technique [0002] Sound barriers are mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources. It is divided into a reflective sound barrier with pure sound insulation and a composite sound barrier with a combination of sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to a wall structure set beside railways and highways to reduce the impact of traffic noise on nearby residents. Sound barriers are also called sound barriers. Insert a facility between the sound source and the receiver to make the sound wave propagate with a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. Such a facility is called a sound barrier. Divided in...
