Background technology
Head tank is the chemical plant common equipment, is used for to the reactor feed flow.In actual production, normally roughly judge by experienced technical staff the amount that is fed to liquid in reactor, for those reactions that accuracy of reaction mass proportioning is had relatively high expectations, often can not reach the reaction result of expectation, thereby affect the quality of production.In addition; in the use procedure of head tank; often use head tank and add continuously several reaction masses; pollution for fear of reaction mass; all needed head tank is rinsed before adding reaction mass at every turn; and existing head tank is not only wasted time and energy when rinsing; and the effect of rinsing is not ideal enough; especially splendid attire is crossed the head tank of caustic soda; because sheet alkali is accompanied with impurity; as untimely, filter out thoroughly, be easy to together enter reactor with alkali lye, finally the quality of product produced harmful effect.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide and a kind ofly can make more accurately the head tank of controlling, guarantee the quality of production to the proportioning of reaction mass, and the convenient cleaning of this head tank.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of caustic soda head tank, comprise: groove body, the top of aforementioned grooves main body is provided with charging aperture, be provided with discharging opening on the sidewall of bottom, it is characterized in that, be connected with discharge pipe on aforementioned discharging opening, be provided with control valve and flowmeter on aforementioned discharge pipe, and aforementioned control valve is connected by signal with the PLC controller; The bottom of aforementioned grooves main body is infundibulate, and is provided with exhaust-valve in the lower end.
Preferably, aforementioned exhaust-valve is connected by signal with aforementioned PLC controller.
Aforesaid caustic soda head tank is characterized in that, aforementioned discharging opening place is provided with the first filter screen.
Preferably, be provided with sealing ring between aforementioned the first filter screen and discharging opening.
Aforesaid caustic soda head tank is characterized in that the top of aforementioned grooves main body is provided with passage.
Preferably, aforementioned passage place is provided with the second filter screen.
Aforesaid caustic soda head tank is characterized in that, also comprises: agitator, the inside that is arranged on groove body that aforementioned agitator is vertical.
Preferably, aforementioned agitator is connected by signal with aforementioned PLC controller.
Usefulness of the present invention is: control valve and flowmeter are set on the discharge pipe of head tank, and control valve is connected with the PLC controller, can do more accurately the proportioning of reaction mass and control, make reaction reach the result of expectation, thereby guaranteed the quality of production of product; Funnel-shaped design is adopted in the bottom of groove body, and is provided with exhaust-valve in the lower end, can effectively discharge the impurity that is sunken to the groove body bottom; Inside at groove body arranges agitator, abundant mixing feed liquid not only, and can guarantee that groove body cleans more thoroughly.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of caustic soda head tank of the present invention.
The implication of Reference numeral in figure: 1-groove body, 2-charging aperture, 3-discharging opening, 4-discharge pipe, 5-control valve, 6-flowmeter, 7-PLC controller, 8-exhaust-valve, 9-the first filter screen, 10-passage, 11-the second filter screen, 12-agitator.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done concrete introduction.
With reference to Fig. 1, caustic soda head tank of the present invention includes groove body 1, the top of groove body 1 is provided with charging aperture 2, be provided with discharging opening 3 on the sidewall of bottom, be connected with discharge pipe 4 on discharging opening 3, and be provided with control valve 5 and flowmeter 6 on discharge pipe 4, control valve 5 is connected by signal with PLC controller 7 again simultaneously, accepts the control of PLC controller 7; The bottom of groove body 1 is infundibulate, and is provided with exhaust-valve 8 in the lower end.Flowmeter 6 is used for metering and is flowed into the amount of the reaction mass in reactor by head tank, can realize the accurate control to the reaction mass proportioning, thereby guarantees that the result of reacting to expectation is close; Control valve 5 is used for controlling the switching of discharge pipe 4, and it is subjected to the control of PLC controller 7, has saved the operation that opens and closes manually valve, not only saves time but also laborsaving, and has guaranteed the security of operation; The exhaust-valve 8 that funnel shaped design and lower end arrange can effectively be discharged the impurity that is sunken to groove body 1 bottom, prevents that impurity from entering into reactor and affecting product quality.
As a kind of preferred scheme, exhaust-valve 8 is connected by signal with PLC controller 7.The switching of exhaust-valve 8 is subjected to the control of PLC controller 7, and is time saving and energy saving, more convenient operation.
Can not enter in reactor in order to ensure the impurity in head tank, as a kind of preferred scheme, discharging opening 3 places of head tank are provided with the first filter screen 9.
