Abstract
The utility model discloses a gas-control type injection device, the structure of which is that the injection device is arranged in a shell, an internal gas inlet pipe with an internal gas nozzle is respectively communicated with a pressure air source and a pressure storage container for injection objects, the internal gas inlet pipe is provided with an internal gas control switch. An external gas inlet pipe is communicated with the pressure air source and is in nested connection with the internal gas nozzle end of the internal gas inlet pipe, a circular air duct is formed between the nested parts of the external gas inlet pipe and the internal gas inlet pipe, the end of the shell at the circular air duct is connected with an external gas adjustable sprayer communicated with the circular air duct, and the external gas inlet pipe is provided with an external gas control switch valve. The utility model can fully take advantage of the spraying materials, can effectively save the raw materials, reduce the production cost, improve the production efficiency, and effectively decrease the pollution to the environment with good spraying effect and environmental protection effect.
Description
Technical field
The utility model relates to a kind of injection apparatus, Pneumatic-control type injection apparatus particularly, and it is applicable to the spraying of paint, coating, powder material, chemicals, biochemical drug and epidemic prevention medicine.
Background technology
Usually, spray paint, coating or when spraying chemicals, agricultural chemicals etc., the injection apparatus of employing forms by spraying thing reservoir vessel and coupled logical shower nozzle and pressing mechanism mostly.Spraying of material from the shower nozzle ejection, is sprayed directly on the body surface under the effect of pressing mechanism.In spraying process, the spraying swath when outwards spraying owing to spraying of material can form Three regions, is humid region, range of atomization and mistake range of atomization from inside to outside successively.Because spraying of material directly sprays from shower nozzle, have certain vapour lock between shower nozzle and the spraying object, in the humid region of ejecta spraying swath and range of atomization, can directly effectively spray on the body surface, and the range of atomization outer rim and cross the range of atomization can be because of the effect of vapour lock, and make the ejection material in course of injection to around fly upward, lost; In addition, also have part ejection material sprayed object rebound away, lost; If spraying of material upwards, this ejection material can be because of reasons such as deadweight, vapour lock or bounce-backs, and can not effectively be fully used.This not only can cause raw-material waste, strengthens production cost, but also pollutes the environment, and bring certain infringement also for the healthy of staff, and production efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of Pneumatic control injection apparatus, and it can overcome the deficiency of prior art, can effectively save raw material, reduces production costs, and can effectively reduce pollution to environment.
Its solution is: be provided with the interior gas air inlet pipe that is connected with interior gas blowout mouth in housing, it is communicated with pressure gas source and injection thing pressure reservoir vessel respectively, and is provided with interior gas control switch processed in interior gas air inlet pipe.The outer gas air inlet pipe that is positioned at housing is communicated with pressure gas source, be connected with the interior gas blowout mouth end suit of interior gas air inlet pipe again, and form annular air channel at them between the two the suit part, on the housing at annular air channel place, be connected with the outer gas adjustable nozzle that is connected with annular air channel, be provided with outside outer gas control switch valve processed on the gas air inlet pipe.
Because the utility model is taked technique scheme, under of the effect of spraying material at pressure gas source, during from the interior gas blowout mouth ejection of interior gas air inlet pipe, the outer gas adjustable nozzle that this spout outside is provided with is simultaneously jet, and at the annular aerosol of the peripheral formation of the material of interior gas blowout mouth ejection, by regulating the open degree of outer gas adjustable nozzle, internally the spraying swath of gas blowout mouth-spray material is controlled, thereby can avoid spraying material and form the fog-zone, the ejection material is sprayed directly on the body surface in the range of atomization.This can not only make spray finishing material be fully used, and not only saves material but also save relevant auxiliary material, thereby can avoid waste of raw materials, reduces production costs, and can enlarge spray area, and spraying effect is good, the production efficiency height.Simultaneously, can also effectively reduce the pollution to environment, preferably environment protecting is arranged, and can guarantee staff's good production environment, effectively reduce their able-bodied harm.
Description of drawings
Accompanying drawing is the structural representation of Pneumatic-control type injection apparatus.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
In the accompanying drawing, an end that is arranged on the interior gas air inlet pipe 10 of housing 2 inner chambers is interior gas blowout mouth 11, and the other end is communicated with pressure gas source 7 through flexible pipe 6, and this pressure gas source 7 is air-pot.Interior gas air inlet pipe 10 between interior gas blowout mouth 11 and pressure gas source 7 is communicated with sprays thing pressure reservoir vessel 9, be provided with gas control switch 8 processed in the handle type on the interior gas air inlet pipe 10 between pressure gas source 7 and injection thing pressure reservoir vessel 9, be used for the discharging of gas in the control.Outer gas air inlet pipe 3 one ends are communicated with pressure gas source 7 through flexible pipe 6, and this pressure gas source can be and interior gas air inlet pipe 10 same pressure gas sources, also can be independent pressure gas source.The other end is connected with the interior gas blowout mouth 11 end suits of interior gas air inlet pipe 10, and between their the two suit parts, form annular air channel 4, housing 2 ends at annular air channel 4 places, be connected with the regulable ring-shaped shower nozzle 1 of the outer gas that is connected with annular air channel 4, and the outer gas air inlet pipe 3 between annular air channel 4 and the pressure gas source 7 is provided with outer gas control system switch valve 5, be used to control the discharging of outer gas, by regulating the regulable ring-shaped shower nozzle 1 of outer gas, make the annular gas of its ejection form aerosol, effective spraying swath of gas blowout mouth 11 ejection materials is convenient to spray effectively in being used to control.
During the spraying object, simultaneously, gas control system switch 8 and injection thing pressure reservoir vessel 9 in opening, spraying of material in this pressure reservoir vessel 9 is under the pressure effect of pressure gas source 7, from interior gas blowout mouth 11 ejections, and open outer gas control system switch valve 5 simultaneously, regulate the regulable ring-shaped shower nozzle 1 of outer gas, the gas that makes its ejection is at the annular aerosol of the peripheral formation of the ejection material of interior gas blowout mouth 11 ejections, under the effect of this annular aerosol, make the ejection material at the range of atomization inner direct to body surface, can not form the range of atomization again.And since the formed ejection material to external diffusion and bounce-back of resistance of body surface also can be grouped into next time the range of atomization in the effect of annular aerosol and be directly injected on the body surface.If spray to body surface from bottom to top, the ejection material can be because of himself gravity fall and diffusion, bounce-back, and these ejection materials can under the effect of the election lift of annular aerosol, rise to the range of atomization equally, be sprayed directly on the body surface, to reach best spraying effect.Spray completely, close immediately relevant gauge tap, get final product.
