Flushing pipeline device

Abstract

The invention discloses a flushing pipeline device used for a concrete mixer. The flushing pipeline device comprises an air channel assembly, a water tank, a water tank support device and a water channel pipe set. The air channel assembly comprises an air manifold, an air channel protection box and an air pipe, and the air channel protection box is communicated with the air manifold and communicated with the air pipe. The top of the water tank is communicated with the air pipe, and the bottom of the water tank is provided with a water inlet pipe and a water outlet pipe. The water tank is fixed on the concrete mixer through the water tank support device. The water channel pipe set comprises a water inlet and a water injection nozzle, and the water inlet is communicated with the water outlet pipe. When the flushing pipeline is used, a first switch is turned on, water is injected into the water tank through the water inlet pipe, after water injection is finished, the first switch is turned off, an air channel protection box switch and a second switch are turned on, air stored in the air manifold enters the water tank after being reduced in pressure through the air channel protection box, and water is pressed into the water outlet pipe through the water tank, then enters the water inlet and is injected out from the water injection nozzle. Due to the air channel protection box, safety is improved, and the flushing pipeline device is easy to operate and more attractive.

Description

technical field [0001] The invention relates to the technical field of flushing, in particular to a flushing pipeline device. Background technique [0002] With the continuous increase in the application of engineering mixer trucks, people's requirements for the diversity of functions of the vehicle itself are getting higher and higher, and the waterway system, as a vehicle cleaning system for engineering mixer trucks, has become more and more important. First of all , as a part of the exterior design of the vehicle, the waterway system is harmonious and unified with the overall design of the vehicle body, and plays a certain decorative role. Secondly, the waterway system is responsible for the cleaning of the vehicle, especially the feed hopper and discharge trough of the mixer truck. As well as the long unloading chute and the inside of the cylinder, these parts are in close contact with the concrete and need to be washed in time after unloading to prevent the remaining co...

Problems solved by technology

[0004] The airway assembly in the conventional waterway system usually adopts a simple pressure reducing valve design, which has a single function, is prone to failure, and needs to be improved in safety. Weak, the aluminum-plastic pipes used need to use special installation tools during the installation process, and it is inconvenient to disassemble in the later maintenance, and the aluminum-plastic pipes are formed straight pipes, the specific layout position is relatively limited, and when the vehicle is transported long-distance bumpy or by sea, The tensile and compressive properties of aluminum-plastic pipes are poor. Generally speaking, the existing waterway system design functions are relatively single, and they are not beautiful enough.
