Description

Air-assisted sprayer pipeline system with rotation compensation and air-assisted sprayer

Technical Field

The utility model relates to a sprayer technical field specifically is a take rotation compensation's air-assisted sprayer pipe-line system and air-assisted sprayer.

Background

At present, visual linkage, dust linkage, gray level identification linkage based on machine vision and other modes are widely adopted in many dusty industrial and mining enterprise material yards of steel, coking, cement and the like, and the accurate dust control of the material yard is realized by regularly, quantitatively and directionally spraying through a linkage air-assisted spraying machine. The air-assisted sprayer generally mainly comprises a fan, a spray ring, a rotating assembly, a base assembly, an electric control system, a pipeline system and the like, wherein the spray ring is positioned at an air outlet at the front end of the fan, a nozzle is arranged on the spray ring, and the atomization process of the spray ring is divided into two processes of primary hydraulic atomization of the nozzle and secondary atomization of high-speed airflow. The primary atomization is a pressure atomization process of liquid flowing out of a nozzle under the action of pumping pressure of a booster pump of a pipeline system; the secondary atomization is that liquid drops are dispersed in air and are crushed and atomized under the extrusion action of high-speed airflow of a fan. The secondary atomization needs to be established on the basis of primary atomization, namely, liquid drops need to be firstly pressurized, continuously and stably conveyed to a spray ring through a pipeline system booster pump and sprayed out through a nozzle, so that the sprayer can fully cover and diffuse the liquid drops to a dust-producing area under the coordination of rotation and pitching motion, and dust can be reliably suppressed. The stability and reliability of the pipeline system are self-evident in important function.

At present, a wind-driven sprayer generally realizes that a fan spray ring nozzle sprays liquid drops to fully cover a dust-generating area and reliably suppress dust through actions in two directions of rotation and pitching. In the pipeline system, the booster pump is arranged on the rotary component and rotates together with the rotary component, and a pressure pipeline from a spray ring at the air outlet of the fan to the water outlet of the booster pump always acts together with the fan. The pressure pipeline from a water source taken by the sprayer to the water inlet of the booster pump is generally divided into two sections, wherein the first section is a water pipeline from the water source to a water passing pipeline fixedly arranged on the base assembly through a bracket; the second section is a water passing pipeline from the base assembly to a water inlet of a booster pump on the rotating assembly, and the pipeline has relative rotation motion due to the fact that the base assembly is connected with the rotating assembly through a rotary driving bearing, so that the pipeline from the water passing pipeline of the base assembly to the water inlet of the booster pump on the rotating assembly must bear relative rotation motion. Conventionally, the communication between a water source and a water inlet of a booster pump on a rotary assembly through a water passing pipeline of a base assembly is realized by using a form of combining a full hard pipe and the rotary joint, the full hard pipe is compact in structure and is convenient for heat preservation treatment in northern use, but the pipeline is fixed and two mounting structural components, namely an upper mounting structural component and a lower mounting structural component of a rotary driving bearing which are in relative rotary motion, namely the base assembly and the rotary assembly are high in manufacturing precision centering requirement and production cost, and in the use and rotation process of an actual sprayer, the hard pipe fixing support is loosened due to insufficient stress unbalance loading of the manufacturing precision centering or high-frequency use, and the hard pipe fixing support cannot provide axial and radial displacement compensation to enable pipelines and joints at hard pipe joints at two ends of the rotary joint to be distorted, cracked and largely leak water. The market also has the way of adopting the rubber hose hookup from rotary joint to booster pump water inlet, utilizes the pliability of hose to guarantee that pressure water source can smoothly carry to the booster pump water inlet through last water piping, gyration center hard tube, rotary joint, rubber hose of base subassembly during the rotation. However, in daily work, in order for the air-assisted sprayer to treat a larger range of dust, the rotation is frequent, the rubber hose can be provided with fewer fixed points, and the rubber hose still needs to be bent and twisted frequently under the condition of bearing pressure, so that the durability of the common rubber hose is not high, and the phenomenon that the hose is rubbed or scratched with other structural components such as a sprayer base assembly, a rotating assembly and the like is inevitable; thirdly, the air-assisted sprayer in the north of the service environment needs to insulate the pipeline, the insulation cotton is generally wound outside the pipeline, the thicker insulation layer enables the bending and twisting of the hose to be more limited, and the insulation layer is easy to break and fall off.
