In order at the convenient more good berth shower nozzle of different atomizes, the syndeton between the syndeton between the skirt section in embodiment 1 and the syndeton (Quick-mounting joint) between rotary clip, the pneumatic hose two ends in embodiment 2 and skirt section, rotary clip, the hard bend pipe in embodiment 3 and skirt section, rotary clip is all identical.
Series excited machine produces enough air quantity and blast, and through the air channel of front end case, blast is brought up to a sufficiently high level, obtains the steady air flow of high speed and high pressure.This high velocity air divides two-way to spray through atomizer, makes nozzle front produce certain negative pressure, causes liquid by siphon to nozzle place, forms higher relative velocity thus realize twice atomization between two-way air-flow and liquid.Atomizer adopts pneumatic atomization principle, and adopts two stage cyclone atomization structure, can produce the droplet of aerosol rank and atomizing rank.
Atomizer and auto take-up are individual components, can carry out integral installation or integral demounting, be convenient to maintenance process simulation.Utilize the Quick-mounting joint be equipped with, according to different spraying operation requirements, the spraying elbow of horizontal spraying joint as described in Example 1, pneumatic hose as described in Example 2 and certain angle is as described in Example 3 installed.Utilize Quick-mounting joint to load onto pneumatic hose, flow adjustment knob is adjusted to high flow capacity, now produces the droplet of atomizing rank, can realize the residual spray on surface.When needs space is sprayed, can select the spraying elbow installing horizontal spraying joint or certain angle, all need flow adjustment knob to be adjusted to low discharge, now will produce the droplet of aerosol rank, this rank droplet can realize filling the air infiltration control.Space is sprayed and is generally carried out timed spays.Do not need rotating spraying during choosing dress horizontal spraying joint, and need rotating spraying, rapid Cover dissipation space during the spraying elbow of choosing dress certain angle.Timed spays function relies on timing means to realize, and can select suitable timing according to epidemic prevention space size.Rotating spraying utilizes rotary control switch to open electric rotating machine and realizes.
Epidemic prevention dissipation machine has three kinds of duties, and horizontal positioned (see Fig. 1), setting place (see Fig. 5) and the side back of the body, and horizontal positioned and setting are placed through bottom complete machine and right-hand member arranges fulcrum 104, fulcrum 105 realizes, and the side back of the body then dependence braces realizes.When installing horizontal spraying joint, being chosen as horizontal positioned or erectting placement two kinds of duties; When installing the spraying elbow of certain angle, recommendation is erect and is placed; When installing pneumatic hose, using the mode of the braces side back of the body to aim at controlling object and carrying out epidemic prevention operation.
Concrete use procedure: (1), according to different epidemic prevention environment and epidemic prevention requirement, select different spraying joints.In open environment or when there is specific epidemic prevention object, elect the residual spray of larger droplet as.Now, rapid-assembling/disassembling joint is utilized to be connected on atomizer by pneumatic hose; If the sealing in epidemic prevention region is higher, complex structure, elects the space spray modes of less droplet as.When space is less, optional dress horizontal spraying joint, when space is larger, the spraying elbow of optional dress certain angle.(2), by complete machine erect and place, open medicine chest cover, in medicine-chest, add injecting medical liquid.After carrying out safety and routine inspection, then attaching plug is extracted out from auto take-up and be inserted in supply socket.(3) if elect residual spray as, flow adjustment knob is adjusted to high flow capacity, utilizes braces side to carry on the back epidemic prevention machine.Opening power gauge tap is to normally open, and generation atomizing of starting working, hand-held pneumatic hose, aims at epidemic prevention object spraying operation.(4) if when electing the space spray modes of installing horizontal spraying joint as, flow adjustment knob is adjusted to low discharge, complete machine is erect and is placed.Timing means is adjusted to suitable timing, and turn on the power switch and be adjusted to time delay open position, operating personnel speed away.Due under this pattern, possess Automatic Time Lag Function, after a period of time, generation aerosol of starting working, realizes the space spraying operation automatically filling the air infiltration.(5) if when electing the space spray modes of the spraying elbow installing certain angle as, and the space sprinkling difference installing horizontal spraying joint is, needs rotating spraying operation.Namely after needing power control switch to open, fast rotary control switch is opened, realize revolution space and spray.(6), the end of job time, powered-down gauge tap, utilizes auto take-up automatically power line to be regained.
There is provided enough air quantity and blast by series excited machine, adopt the pneumatic atomization mode of two-stage centrifugal impeller.While ensureing atomization quality, guarantee that equipment is reliable; By the micromachine in motor case, through swivel joint, rotate the crucial connection switching member drive such as liquid collecting bar, rotary clip shower nozzle rotation implementation space sprinkling, whole system compact conformation.
This technology is a kind of light, compact conformation, easy to maintenance, perfect in shape and function, possess that space is sprayed, the multi-functional epidemic prevention dissipation machine of residual spray two kinds of work patterns, also achieve the function of delayed start-up and timed spays, the flow sprayed is adjustable, mist droplet particle size is adjustable, the direction of spraying can manually and automatic rotation, complete machine can level sleeping to put, uprightly place, portable, the side back of the body, be a kind of epidemic prevention dissipation machine of multi-function operation.
