Abstract
A double-balance-floater flow controller is characterized by comprising two balance barrels, two balance floaters, a liquid storage tank and a disk dredging box, wherein the two balance barrels are placed in an overlapped mode, an inlet of the upper balance barrel is connected with a discharge port in the bottom of a high-position barrel through a pipeline, an opening is formed in the lower portion of the upper balance barrel and communicated with an inlet of the lower balance barrel through a liquid inlet and outlet pipeline, one balance floater is arranged in each balance barrel, the lower balance barrel is communicated with the liquid storage tank through a liquid inlet hole, and the disk dredging box is installed in the liquid storage tank. The disk dredging box is driven by a variable frequency motor, and the purpose for adjusting the flow amount of material is achieved by adjusting the rotation speed of the variable frequency motor. According to the double-balance-floater flow controller, the double balance floaters are adopted for controlling the height of the liquid level of material in the lower layer balance barrel and making the height of the liquid level of the material in the lower layer balance barrel constant; the disk dredging box is in cooperation with the variable frequency motor to adjust the flux of the material, therefore, the adjusting process of the flux is greatly optimized, the automation degree of equipment is improved, labor intensity of workers is greatly lowered, production cost is lowered, and direct yield of products is improved.
Description
Technical field
The present invention relates to a kind of flow controller.
Background technology
Existing flow controller is single displacer and hand control valve gate-type flow controller, its principle of work is to utilize displacer to control the liquid level of material in the balance bucket, and make it to keep constant in the process of operation, thereby keep pressure constant everywhere of material in the balance bucket.Utilize the aperture of manual shift balance bucket bottom fluid valve to carry out the size of adjust flux.This flow controller in actual use, variation along with material liquid surface height in high-order bucket, in the balance bucket, the liquid level of material can not keep constant, also can fluctuate thereupon, thereby cause the fluctuation of flow controller flow, make the flow of flow controller can't keep constant, and then affect the stability of product quality and the direct yield of product; In addition, because being adopts manual valve to carry out the size of adjust flux, when starting cell body, be difficult to be transferred in the shorter time flow of technological requirement, like this, when starting cell body, some time material is actual enters the flow of cell body and the flow of technological requirement is not inconsistent, this can make cell body produce certain fluctuation, and then, also the direct yield stable and product of product quality produced to certain adverse influence.
Summary of the invention
The object of the present invention is to provide a kind of pair of displacer flow controller, overcome that single displacer and hand control valve gate-type flow controller balance bucket liquid level easily fluctuate, the shortcoming of instability of flow.
A kind of pair of displacer flow controller, it is characterized in that: comprise two balance buckets, two displacers, reservoir, disk bailing bucket, the overlapping placement of two balance buckets, the import of upper balance bucket is connected by pipeline with the discharging opening of high-order bottom of the barrel, upper balance bucket lower openings, be communicated with the import of lower balance bucket by the liquid in-out pipeline, and a displacer is all arranged in each balance bucket, lower balance bucket is communicated with reservoir by inlet opening, and the disk bailing bucket is arranged in reservoir.
Further, the disk bailing bucket adopts variable-frequency motor to drive, and reaches the purpose of regulating the material uninterrupted by the rotating speed of regulating variable-frequency motor.
Advantage of the present invention is: the liquid level of the material in lower balance bucket only is subject to the impact (in upper balance bucket, the variation of material liquid surface height is no more than 1cm) of material liquid surface height in the balance bucket, and is not subject to the impact (in high-order bucket, the height change of material liquid surface maximum is about 200cm) of material liquid surface height change in high-order bucket.Thereby greatly improved the stability of material liquid surface height in time balance bucket, and then improved the stability of product quality, reduced production cost, improved the direct yield of product.In addition, adopt the disk bailing bucket to coordinate the mode of variable-frequency motor to replace the mode of hand control valve gate-type to regulate mass flow, greatly optimized the adjustment process of flow, improved the automaticity of equipment, greatly reduced workman's labour intensity, eliminated the caused cell body of manual shift flow and produced degradation harmful effect under fluctuation, product quality decline, production cost rising, product direct yield.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
L-type bailing bucket 1, disk 2, disk bailing bucket 3, spout hole 4, reservoir 5, inlet opening 6, taper fluid discharger 7, fixedly supporting plate 8, displacer 9, hold-down nut leakage device 10, spell jack panel 11, liquid in-out pipeline 12, holder liquid bath 13.
Embodiment
Now the invention will be further described in conjunction with the accompanying drawings and embodiments:
As shown in Figure 1, a kind of pair of displacer flow controller, it is characterized in that: comprise two balance buckets, two displacers, reservoir 5, disk bailing bucket 3, the overlapping placement of two balance buckets, the import of upper balance bucket is connected by pipeline with the discharging opening of high-order bottom of the barrel, upper balance bucket lower openings, by liquid in-out pipeline 12, with the import of lower balance bucket, be communicated with, a displacer 9 is all arranged in each balance bucket, lower balance bucket is communicated with reservoir 5 by inlet opening 6, disk bailing bucket 3 is arranged in reservoir 5, and spout hole 4 is arranged at reservoir 5 tops.Disk bailing bucket 3 comprises L-type bailing bucket 1 and disk 2, and disk bailing bucket 3 adopts variable-frequency motor to drive, and reaches the purpose of regulating the material uninterrupted by the rotating speed of regulating variable-frequency motor.Taper fluid discharger 7 is fixed on fixedly on supporting plate 8 by spelling jack panel 11 and hold-down nut leakage device 10, makes taper fluid discharger 7 vertical with surface level, with the conical surface of guaranteeing taper fluid discharger 7, with the effective of the conical surface of disk float 9, coordinates.
Because the height of material liquid surface in single balance bucket can change with the height change of material liquid surface in high-order bucket, in high-order bucket, the height change of material liquid surface maximum is about 200cm, correspondingly causes that the height change of material liquid surface maximum in single balance bucket is about 1cm.After adopting two balance bucket designs, the liquid level difference that causes the top material of material liquid surface height change in lower balance bucket becomes 1cm from 200cm, dwindle 200 times, thereby greatly improved the stability of material liquid level in time balance bucket, and then improved the stability of flow controller flow.In addition, adopt the disk bailing bucket to coordinate the mode of variable-frequency motor to replace the mode of hand control valve gate-type to regulate mass flow, greatly optimized the adjustment process of flow, improved the automaticity of equipment, greatly reduced workman's labour intensity, eliminated the caused cell body of manual shift flow and produced degradation harmful effect under fluctuation, product quality decline, production cost rising, product direct yield.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention; make without departing from the inventive concept of the premise some alternative or obvious modification that are equal to; and performance or purposes identical, should be considered as belonging to the definite protection domain of claims that the present invention submits to.
