Combined spraying device capable of adding liquid accelerator separately and working method of combined type spraying device

Abstract

The invention discloses a combined spraying device capable of adding a liquid accelerator separately and a working method thereof, and relates to the technical field of building construction. The combined spraying device comprises a transport vehicle, a carrying plate is fixedly arranged at the top of the transport vehicle, supporting plates are fixedly arranged on the front face and the back face of the carrying plate correspondingly, and a stirring box is fixedly arranged at the top of the carrying plate, a feeding hopper is fixedly arranged at the top of the stirring box, a rotating motor is fixedly arranged on the front face of the stirring box, a stirring shaft is fixedly arranged on an output shaft of the rotating motor, a blade-dividing fan blade is fixedly arranged on the outer wall of the stirring shaft, and a flow guide pipe is fixedly arranged at the bottom of the stirring box. A first storage box is fixedly arranged at the bottom of the flow guide pipe; a first liquid pump is fixedly arranged on one side of the first material storage box, a liquid separation accelerator in the first material storage box can enter the second material storage box through the first liquid pump, and a telescopic pipe and a connector which are arranged in a threaded mode are beneficial to combination and installation of the whole structure.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a combined injection device for adding a liquid-separating quick-setting agent and a working method thereof. Background technique [0002] Liquid accelerator is a new generation of high-efficiency multifunctional accelerator scientifically synthesized by inorganic salt and organic polymer materials. It is suitable for sprayed concrete construction, underwater concrete and plugging and emergency projects. Liquid accelerator is pumped or The pneumatic adding device is added at the rear end of the nozzle of the spray pipe, and the amount of addition is controlled by the scale knob, which can be fine-tuned according to the effect of sprayed concrete and the amount of rebound. The mixed concrete is sent to the sprayer, and the liquid quick-setting agent is added outside the nozzle. [0003] In the prior art, the common injection devices added with liquid-separating acce...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the common injection devices added with liquid-separating accelerators are mostly transported and set up by transport vehicles, but the injection structure and the transport vehicles are mostly integrated designs, and the overall volume of the structure is relatively large, resulting in certain narrow locations that are not conducive to It is difficult to operate the spraying device for spraying, and the spraying device is not easy to replace and assemble, which makes it difficult to quickly solve the problem of blockage or reduced spraying efficiency of the spraying device
