Description
Technical field
The invention belongs to rare earth extraction device technique field, be specifically related to a kind of rare earth feed liquid flow automatic control device.
Background technology
As is known in the industry, in the process of extracting rare-earth, the feed liquid that needs to be formulated in header tank according to the extraction process requirement is introduced subsequent handling as extraction tank extraction (filling extraction agent in extraction tank) as rare-earth chloride solution, and whether the stablizing of feed liquid flow in header tank can directly affect the extraction quality, therefore controlling the feed liquid flow be formulated in header tank is the very important technical factor that ensures the extraction quality.Yet, because the reduction of feed volume in header tank is dynamic, by how to reduce gradually, thereby cause pressure reduction (pressure difference) to change, and the pressure reduction variation is totally unfavorable to stability of flow, when pressure reduction is large, the reduction of feed volume flowed in extraction tank is relatively large, otherwise reduces, cause the reduction of feed volume in extraction tank unbalanced, not only affect quality product, and cause rare earth to run off, affect the comprehensive yield of rare earth.
Theoretically, flowrate control valve is set on the pipeline between header tank and extraction tank perhaps can be addressed the above problem, but the production practice long-term through the applicant show, because damage, the obstruction probability of flowrate control valve are higher, thereby inspection trouble, often be difficult to the early stage of especially breaking down at flowrate control valve even can't be found by the workman, only just find after investigation when serious quality problems appear in product, but late.In addition, because the opening degree of flowrate control valve is regulated artificially, thereby levels of precision can't meet processing requirement.Especially, due to factor analysis such as the experience to flowrate control valve operating effect and workman, sense of responsibility and even emotional change, so the stabilising effect of flow is according to the people and the time and different.If adopt programmable controller (PLC), the flowrate control valve with automation function is carried out to flow control, large due to input cost so and operation level or claim that operational requirement is harsh, thereby often hang back for common medium and small sized enterprises, moreover automatization control needs power supply to support.
For above-mentioned prior art, the applicant has done long-term and useful exploration, finally finds a way to resolve the problem, and has formed technical scheme described below.
Summary of the invention
Task of the present invention is to provide a kind of rare earth feed liquid flow automatic control device of fully guaranteeing that the feed liquid in header tank is used guarantee extraction quality and avoided rare earth to run off to the extraction tank conveying of subsequent handling with stable flow that contributes to.
Task of the present invention completes like this, a kind of rare earth feed liquid flow automatic control device, comprise a pressurizer tank, being provided with a feed liquor communicated with the pressurizer tank chamber of pressurizer tank with horizontality below an end of this pressurizer tank takes over, the end that this feed liquor is taken over is stretched over outside the pressurizer tank chamber, and be provided with a valve, and the other end that feed liquor is taken over is stretched in the pressurizer tank chamber, and be connected with a liquid overflow pipe, the chamber diapire in the bottom of this liquid overflow pipe and pressurizer tank chamber is fixed, and this liquid overflow pipe and feed liquor form vertical relation between taking over, be provided with a feed liquid communicated with the pressurizer tank chamber in the middle position of the other end and the short transverse that be positioned at substantially pressurizer tank of pressurizer tank with horizontality and draw adapter, one lever column, this lever column keeps vertical parallel state and the described chamber diapire in described pressurizer tank chamber to fix in the position corresponding to described liquid overflow pipe and with liquid overflow pipe, one fluid liquid cap, this fluid liquid cap floating ground is provided in the upper end of described liquid overflow pipe, and offers liquid-through hole on the wall body of this fluid liquid cap, and liquid-through hole communicates with the cap chamber that goes out the hydrorrhea cap, and the cap chamber communicates with the discharge tube chamber of liquid overflow pipe, be positioned at a lever and a float in described pressurizer tank chamber, an end of lever is connected with described fluid liquid cap, and middle part is connected with the upper end of described lever column, and float is connected to the other end of lever.
In a specific embodiment of the present invention, be equipped with a voltage stabilizing case lid for the pressurizer tank chamber is covered at the top of described pressurizer tank.
In another specific embodiment of the present invention, form a lever pivots mating cavity is arranged in the upper end of described lever column, respectively offer a lever swivel pin axis hole on the mating cavity chamber wall faced each other of this lever pivots mating cavity and in mutually corresponding position, the described middle part of described lever is placed in described lever pivots mating cavity and offers a lever hinge hole, the lever hinge hole is corresponding with lever swivel pin axis hole, and insert successively lever swivel pin axis hole and lever hinge hole and pivotally connected with described mating cavity chamber wall by the lever hinging pin shaft.
In another specific embodiment of the present invention, the quantity that is opened in the described liquid-through hole on described fluid liquid cap has two, and these two liquid-through holes keep aspectant position relationship each other.
In another specific embodiment of the present invention, described liquid-through hole is circular port or rectangular opening.
Also have a specific embodiment of the present invention, described circular port is slotted eye.
More of the present invention and in specific embodiment, be fixed with the hinged ear of lever that a pair of position corresponds to each other at the top of described fluid liquid cap, a described end of described lever is articulated and connected with the hinged ear of a pair of lever between corresponding to the hinged ear of a pair of lever by hinged ear bearing pin.
