Layer-by-layer spraying equipment for insulated layers on heat distribution pipeline

Abstract

The invention relates to the field of spraying, in particular to layer-by-layer spraying equipment for insulated layers on a heat distribution pipeline. The equipment comprises a workbench; a transfer table; a first pipeline fastening assembly arranged at one end of the workbench; a second pipeline fastening assembly arranged at the end, away from the first pipeline fastening assembly, of the workbench; a rotating mechanism arranged at the end, provided with the first pipeline fastening assembly, of the workbench; a translation mechanism arranged at the end, provided with the rotating mechanism, of the workbench; a spraying mechanism and an angle adjusting mechanism which are arranged in the middle of the workbench; two cutting mechanisms and two stripping mechanisms which are arranged on the two sides of the workbench correspondingly; and a supporting device which comprises two supporting roller shafts and four compression sliding mechanisms, wherein the two supporting roller shafts are horizontally arranged at the upper end of the workbench in parallel. The problems that insulated layers of an existing heat distribution pipeline cannot be sprayed in all directions, spraying efficiency is low, spraying is not uniform, applicability is not wide, safety is low, the surrounding environment is greatly affected, and the health of workers is harmed are solved.

Description

technical field [0001] The invention relates to the field of spray coating, in particular to a layer-by-layer coating equipment for thermal insulation middle layers of thermal pipelines. Background technique [0002] Heat pipes, also known as heat pipe networks, start from the boiler room, direct-fired machine room, heating center, etc., and lead from the heat source to the heat supply pipe of the building's heat entrance. Multiple heating pipes form a pipe network. The design pressure of the heating water medium is less than or equal to 2.5MPa, and the design temperature is less than or equal to 200°C; the design pressure of the heat supply steam medium is less than or equal to 1.6MPa, and the design temperature is less than or equal to 350°C. The outer wall of the pipe is protected by coating the insulation layer layer by layer. Most of the existing heat pipe insulation layer coating is artificially sprayed, which generally cannot be sprayed in all directions, the sprayin...

Problems solved by technology

The design pressure of the heating water medium is less than or equal to 2.5MPa, and the design temperature is less than or equal to 200°C; the design pressure of the heat supply steam medium is less than or equal to 1.6MPa, and the design temperature is less than or equal to 350°C. The outer wall of the pipe is protected by coating the insulation layer layer by layer. Most of the existing heat pipe insulation layer coating is artificially sprayed, which generally cannot be sprayed in all directions, the spraying efficiency is low, the spraying is uneven, the applicability is not wide, and the safety Low, great impact on the surrounding environment, damage to workers' health and other issues
