Abstract

The invention relates to a wet spraying machine of concrete drier, which comprises a spraying machine, a water pressure booster and a powdered accelerator adder. The wet spraying machine of concrete drier integrates the advantages of a dry spraying machine and a wet spraying machine, achieves the upgrade of the concrete spraying technology, improves the sealing performance and reduces the dust generation and the pipe plugging times. The water pressure booster is designed to enable the water pressure to be higher than the wind pressure; water is added into a concrete conveying rubber pipe, so that water and concrete are effectively mixed to achieve the operating process of wet spraying of dry material. The invention has simple operation and can achieve the effects of low rebound and less power. The powdered accelerator adder enables the powdered accelerator to be quantitatively, uniformly and continuously added in the wet spraying process.

Description

technical field [0001] The utility model relates to concrete spraying support equipment used for underground engineering constructions such as tunnels, mines, coal mines, and subways, and relates to a concrete dry material wet spraying machine. Background technique [0002] The shortcoming that existing concrete dry spraying machine exists during operation is: 1. the dust that produces is bigger. Due to the unreasonable sealing structure of the dry spraying machine, there is a lot of dust around it; ②The contact time between the water added at the spray gun and the concrete is very short, and the water pressure is lower than the wind pressure, so that the concrete cannot be fully wetted effectively, and more dust is formed. Dust and larger concrete rebound. ③ It uses powdered quick-setting agent, which is artificially added, which is neither uniform nor continuous, resulting in increased rebound of concrete and wasting concrete. ④ The scattering of cement dust and the wast...
