The liquid level detecting device comprises a contact type liquid level detector and a sleeve which is vertically fixedly arranged in liquid medicine in the head tank and is higher than a liquid level, and a probe of the contact type liquid level detector stretches into liquid medicine in the sleeve. The liquid level detecting device provided by the invention has the advantages of strong antijamming capability, high reliability and the like.
Description
Technical field
The present invention relates generally to food, medical packaging apparatus field, refers in particular to a kind of liquid level detection device that is used for the rotary elevated tank of infusion filling machine.
Background technology
In the rotary elevated tank of infusion filling machine liquid level detection device is housed generally, is used for controlling the liquid level of elevated tank herb liquid.The liquid level detection device that is used for the rotary elevated tank of infusion filling machine in the prior art adopts the contact liquid level detector mostly, stretches into the probe of contact liquid level detector in the soup and detects.Because elevated tank is in the slew mode of speed change during equipment work, the while feed tube is feed liquor constantly, all can cause the soup fluctuation, and the liquid level of fluctuation directly causes the testing result fluctuation of contact liquid level detector, influences the accuracy of liquid level control.Moreover; At the contact liquid level detector is under the situation of capacitance type liquid level detector; Because the capacitance type liquid level detector is measured the capacitance variations between the two poles of the earth with the probe and the high-order cell wall of detector as the two poles of the earth of electric capacity; So the incomplete rule of elevated tank shape, and the error in mounting position of capacitance type liquid level detector all can cause in the elevated tank rotary course; The parasitic capacitance that changes between the probe of high-order cell wall and capacitance type liquid level detector, interference capacitors formula liquid level detector testing result.
Summary of the invention
The technical matters that the present invention will solve is: the deficiency to prior art exists provides the liquid level detection device that is used for the rotary elevated tank of infusion filling machine that a kind of antijamming capability is strong, reliability is high.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of liquid level detection device that is used for the rotary elevated tank of infusion filling machine comprises that contact liquid level detector and vertically is fixedly arranged in the elevated tank soup and exceeds the sleeve pipe of liquid level, and the probe of said contact liquid level detector stretches in the soup in this sleeve pipe.
As further improvement of the present invention:
Said sleeve pipe and contact liquid level detector are fixed on the same supporting component relatively still.
Said sleeve pipe is connected with supporting component through steel wire.
Said sleeve pipe top is provided with and is used for cleaning assembly that elevated tank and sleeve pipe are cleaned and sterilize, and said cleaning assembly comprises purge pipe and is positioned at the spray ball of purge pipe end.
The radial dimension of said sleeve pipe is greater than its axial dimension.
Compared with prior art, the invention has the advantages that:
1, the present invention through in the elevated tank soup, set firmly one exceed liquid level sleeve pipe, the probe of contact liquid level detector is stretched in the soup in the sleeve pipe; When fluctuation appearred in the soup in the elevated tank, sleeve pipe can play buffer action, slows down liquid fluctuating and in sleeve pipe, transmits, and the soup liquid fluctuating amplitude in the sleeve pipe is reduced, thereby improved the accuracy of contact liquid level detector testing result, and reliability is high.
2, the capacitance type liquid level detector among the present invention is with the probe of detector and casing wall the two poles of the earth as electric capacity, because detector is static relatively with sleeve pipe, thus the parasitic capacitance that can not change between detector and the sleeve pipe, the accuracy of assurance testing result.
3, sleeve pipe of the present invention is connected with supporting component through steel wire, owing to steel wire takes up room for a short time, is convenient to cleaning liquid and sterilisation vapour sleeve pipe is carried out cleaning and sterilizing.
4, the radial dimension d of sleeve pipe of the present invention can reduce the sprinkling dead angle of spray ball greater than its axial dimension h, is convenient to on-line cleaning and online sterilization.
Description of drawings
Fig. 1 is the present invention's structural representation in an embodiment.
Marginal data: 1, liquid inlet control valve; 2, feed tube; 3, contact liquid level detector; 4, steel ring; 5, steel wire; 6, sleeve pipe; 7, elevated tank; 8, supporting component; 9, spray ball; 10, purge pipe.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further explain.
As shown in Figure 1; The liquid level detection device that is used for the rotary elevated tank of infusion filling machine of the present invention; Comprise that contact liquid level detector 3 and vertically is fixedly arranged in elevated tank 7 soups and exceeds the sleeve pipe 6 of liquid level; Sleeve pipe 6 in the present embodiment adopts round steel pipe, and the probe of contact liquid level detector 3 stretches in the soup in this sleeve pipe 6.During liquid drug, liquid inlet control valve 1 control soup gets into feed tube 2, and feed tube 2 inserts in the elevated tank 7 that rotates and carries out feed flow; When the speed change rotation of elevated tank 7 and feed tube 2 continuous feed liquors cause elevated tank 7 herb liquids fluctuation to occur; Sleeve pipe 6 can play buffer action; Slowing down liquid fluctuating transmits in sleeve pipe 6; Soup liquid fluctuating amplitude in the sleeve pipe 6 is reduced, thereby improve the accuracy of contact liquid level detector 3 testing results, reliability is high.
In the present embodiment, sleeve pipe 6 is fixed on the same supporting component 8 with contact liquid level detector 3 relatively still.Wherein, sleeve pipe 6 is lifted on the steel ring 4 through steel wire 5, and steel ring 4 is fixed on the supporting component 8.Because contact liquid level detector 3 is static relatively with sleeve pipe 6, so the parasitic capacitance that can not change between contact liquid level detector 3 and the sleeve pipe 6 can guarantee the accuracy of testing result; Sleeve pipe 6 is connected with supporting component 8 through steel wire 5, owing to steel wire 5 takes up room for a short time, is convenient to cleaning liquid and sterilisation vapour sleeve pipe 6 is carried out cleaning and sterilizing.
In the present embodiment, sleeve pipe 6 tops are provided with and are used for cleaning assembly that elevated tank 7 and sleeve pipe 6 are cleaned and sterilize, and cleaning assembly comprises purge pipe 10 and the spray ball 9 that is positioned at purge pipe 10 ends.When elevated tank 7 cleanings or sterilization, cleaning liquid or sterilisation vapour are sprayed in elevated tank 7 and the sleeve pipe 6 by spray ball 9 through purge pipe 10.The radial dimension d of the sleeve pipe 6 in the present embodiment can reduce the sprinkling dead angle of spray ball 9 greater than its axial dimension h, is convenient to on-line cleaning and online sterilization.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art some improvement and retouching not breaking away under the principle of the invention prerequisite should be regarded as protection scope of the present invention.
