Adding device of liquid accelerator

Abstract

The invention discloses an adding device of a liquid accelerator. The adding device of a liquid accelerator comprises a shell, a material mixing cavity, a water inlet pipe, a feeding pipe and a suction device; the material mixing cavity is arranged at an inner lower part of the shell, one end of the water inlet pipe extends into the material mixing cavity from one side of the shell, an upper end of the feeding pipe is connected with a lower end of the material mixing cavity, and the other side of the shell is connected with a discharging pipe; the suction device comprises a cover body, a connecting pipe, a first piston assembly and a control rod, the cover body is slidably arranged in the shell, a second piston assembly is arranged on the cover body, the connecting pipe is slidably arranged in the material mixing cavity, an upper end of the connecting pipe is connected with the cover body, and the first piston assembly comprises a first piston rod and a first piston; an upper end of the first piston rod is inserted into the connecting pipe and connected with the cover body, a lower end of the first piston rod is inserted into the feeding pipe, the first piston is connected with a lower end of the first piston rod, and the control rod is inserted into the connecting pipe from the cover body; and the second piston assembly, the first piston rod and the control rod are connected through a linkage mechanism. The adding device of a liquid accelerator ensures accurate metering and uniform adding of the liquid accelerator.

Description

technical field [0001] The invention relates to the field of liquid medicine adding equipment, in particular to a liquid accelerator adding device. Background technique [0002] The raw materials used in the mine underground dry shotcrete support process include cement, sand and gravel mixture, water and a corresponding proportion of dry powder quick-setting agent. The dry powder quick-setting agent is added in the spraying machine The mouth is metered with the mixture, mixed with water at the nozzle with the high-pressure delivery pipe, and sprayed on the support surface. The rebound rate is as high as 30-40% during the spraying process, and because the proportion is not easy to control, the mixing is uneven. , resulting in unstable quality of shotcrete entities. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a liquid accelerator adding device. [0004] The present invention is achieved thro...
