Description
Technical field
The utility model relates to a kind of fluid level control device.
Background technology
Printing ink is in forming process; Just the prescription of printing ink and liquid ink resin fully mix in tank diameter; Existing tank diameter is sent into liquid in the tank diameter with pumping after the robotization flowmeter is set required flow, though the flow control that flows in the tank diameter has been got well; But can't precisely detect liquid level at the groove inner height; In case because operating personnel set the error of the careless mistake or the flowmeter fault of flow, then can cause liquid flooding to groove, to cause damage or contaminated environment, also influence the quality of product simultaneously.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, provides a kind of and can prevent the fluid level control device of liquid flooding to tank diameter.
The technical scheme of the utility model is achieved in that a kind of fluid level control device; Said fluid level control device is installed on the tank diameter; The top of said tank diameter is provided with the conduit with the internal communication of tank diameter; One end of said conduit is provided with pumping; The flowmeter of setting predetermined value is installed on the said conduit; Said fluid level control device comprises ultrasonic liquid level gauge, tuning-fork type liquid level gauge and programmable logic controller (PLC), and said pumping is connected with programmable logic controller (PLC), and said ultrasonic liquid level gauge, tuning-fork type liquid level gauge are installed in the top of said tank diameter respectively and stretch in the said tank diameter; The length of said tuning-fork type liquid level gauge distance from bottom tank diameter bottom is less than the length of said ultrasonic liquid level gauge distance from bottom tank diameter bottom, and said tuning-fork type liquid level gauge, ultrasonic liquid level gauge are connected with said programmable logic controller (PLC) respectively.
Preferably, the length at the top of the said tank diameter of distance from bottom of said tuning-fork type liquid level gauge is 10-15cm.
Preferably, said ultrasonic liquid level gauge is positioned at the center at said tank diameter top.
Preferably, the demonstration control instrument is installed on the said tank diameter, said demonstration control instrument is connected with said tuning-fork type liquid level gauge, ultrasonic liquid level gauge respectively.
The utility model advantage is: ultrasonic liquid level gauge, tuning-fork type liquid level gauge are installed in the top at tank diameter; Can detect the height of liquid in the tank diameter, the mixed liquor in tank diameter surpasses the tuning-fork type liquid level gauge, then can give the alarm; Mixed liquor in tank diameter surpasses the ultrasonic liquid level gauge; Then the PLC controls pumping stops to tank diameter input liquid, even like this because personnel do not deal with the tank diameter that gives the alarm, can guarantee that also the liquid that can not in the tank diameter overflows tank diameter.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the head synoptic diagram of present embodiment.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Consult shown in Figure 1; The technical scheme of present embodiment is achieved in that a kind of fluid level control device; Fluid level control device is installed on the tank diameter 1, and the top of tank diameter 1 is provided with the conduit with the internal communication of tank diameter 1, and an end of conduit is provided with pumping 6; The flowmeter of setting predetermined value is installed on the conduit; Fluid level control device comprises ultrasonic liquid level gauge 2, tuning-fork type liquid level gauge 3 and programmable logic controller (PLC) 5, and pumping 6 is connected with programmable logic controller (PLC) 5, and ultrasonic liquid level gauge 2, tuning-fork type liquid level gauge 3 are installed in the top of tank diameter 1 respectively and stretch in the tank diameter 1; The length of tuning-fork type liquid level gauge 3 distance from bottom tank diameters 1 bottom is less than the length of ultrasonic liquid level gauge 2 distance from bottom tank diameters 1 bottom, and tuning-fork type liquid level gauge 3, ultrasonic liquid level gauge 2 are connected with programmable logic controller (PLC) 5 respectively.
The length at the top of the distance from bottom tank diameter 1 of the tuning-fork type liquid level gauge 3 of present embodiment is 10-15cm, and ultrasonic liquid level gauge 2 is positioned at the center at tank diameter 1 top.
After pumping 6 got in the tank diameter 1 by programmable logic controller (PLC) 5 control startups, the liquid level in the tank diameter 1 can slowly rise to the liquid level that flowmeter sets, behind the numerical value of setting on the arrival flowmeter; Pumping 6 can stop input liquid ink resin in tank diameter automatically, shows that control instrument 4 shows liquid level in the tank diameter 1, if flowmeter control is not normal; Liquid in the tank diameter 1 can surpass predetermined altitude, when liquid rises to tuning-fork type liquid level gauge 3 lower ends, shows that then control instrument 4 can send ultra level alarm; And when the untimely processing of operating personnel tank diameter 1; Liquid level can slowly rise to the bottom of ultrasonic liquid level gauge 2 again, and in a single day ultrasonic liquid level gauge 2 bottoms touch liquid, then can transmit a stop signal and give programmable logic controller (PLC) 5; Programmable logic controller (PLC) 5 control pumpings 6 stop in tank diameter 1, to carry the liquid ink resin; Such control safeguard measure just can not make the liquid resin in the tank diameter 1 excessive, thereby environmental pollution has reduced unnecessary loss.
Above embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the people that is familiar with this technology understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
