Novel protected scope.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", should be interpreted broadly " being connected ", " connection ", for example, it may be fix connection, it is also possible to be to removably connect, or integratedly
Connect；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, can be in conjunction with in concrete condition understanding
State term concrete meaning in this utility model.
Embodiment 1
As it is shown in figure 1, this utility model provides a kind of spray equipment preventing spray nozzle clogging, including spray pipeline 1 He
Liquid feeding pipeline 2, connects on spray pipeline 1 and has multiple nozzle 3, and liquid feeding pipeline 2 connects with spray pipeline 1, air supply pipe therein
Road 4 is connected directly between on liquid feeding pipeline 2, and liquid feeding pipeline 2 is provided with the first control valve 5 controlling spray pipeline 1 feed liquor, air supply pipe
Road 4 is provided with the second control valve 6 controlling spray pipeline 1 air inlet.
Existing spray equipment is only improved by this utility model a little, can realize nozzle and exempt from blocking.By existing
A supply air line 4 is increased on some spray pipelines 1, in use, after liquid feeding pipeline 2 end of job, after i.e. spray stops,
Close the first control valve 5, open the second control valve 6, utilize the pressure of air that the medicinal liquid remained in spray pipeline 1 is forced row
Go out, without the medicinal liquid of residual, crystal or jelly would not be had at nozzle 3 to generate, it is to avoid block at nozzle 3.
Embodiment 2
As in figure 2 it is shown, compared with Example 1, embodiment 2 adds the automaticity of spray equipment, this utility model
Being additionally provided with a master controller 7 in spray equipment, master controller 7 controls opening of the first control valve 5 and the second control valve 6 respectively
Close.Certainly, preferably master controller 7 is PLC here, and the first control valve 5 and the second control valve 6 are respectively preferably pneumatic
Control valve, periodically can be cleaned spray pipeline 1 and nozzle 3 by PLC, substantially increases the cleaning effect of nozzle
Rate.
In this utility model, master controller 7 controls the keying of the second control valve 6 in batch (-type), i.e. will by an impulse form
Residual liquid in nozzle 3 and spray pipeline 1 carries out rapid cleaning.
In once cleaning, i.e. master controller 7 is after controlling the first control valve 5 cut out, continuous control the second control valve 6
