Problems solved by technology

[0004] However, as the hydraulic pressure in the overflow tank changes, the flow of the overflow liquid will be unstable, and it is necessary to manually adjust the opening of the valve to restore the flow to the preset flow

Embodiment Construction

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0040] refer to figure 1 , figure 1 An overflow control system 1 for a thickener in this embodiment is shown. The overflow control system 1 can automatically control the flow rate of the overflow liquid returning to the thickener 2 .

[0041] The overflow control system 1 includes a receiving pipeline, an overflow tank 11, a first delivery pump 12, a flow meter 14, a reversing valve group 18, and a control unit.

Abstract

The invention discloses an overflow control system for a thickener. The overflow control system comprises an overflow tank, a liquid return pipeline, a first conveying pump, a flow meter and a controlunit, wherein the overflow tank is used for receiving overflow liquid outputted from the thickener; the liquid return pipeline is used for injecting the overflow liquid into the thickener; the firstconveying pump comprises a first inlet communicated with the overflow tank and a first outlet communicated with the liquid return pipeline; the flow meter is used for measuring the flow rate of the overflow liquid in the liquid return pipeline; and the control unit is connected with the first conveying pump and the flow meter, and is used for adjusting the output flow rate of the first conveying pump according to a difference value between the flow rate measured by the flow meter and the preset flow rate when the first outlet is communicated with the liquid return pipeline, so that the outputflow rate of the first conveying pump is equal to the preset flow rate. With the adoption of the overflow control system, the control precision of the return flow rate of the overflow liquid can be greatly improved, so that the manual adjustment load is reduced.

Description

technical field [0001] The present invention generally relates to thickener technology, and in particular, relates to an overflow control system for a thickener. Background technique [0002] Thickener is a relatively common thickening equipment, mainly used for solid-liquid separation, or solid material classification, and is widely used in mining, municipal, electric power, chemical, metallurgical and other industrial sectors. [0003] The overflow liquid overflowing from the thickener will be collected into the overflow tank, and part of the overflow liquid in the overflow tank needs to be pumped back to the flocculant mixer of the thickener to dilute the flocculant. The flow of overflow liquid sent back to the thickener is controlled by setting a manual valve on the delivery pipeline of the water pump. Manually adjust the opening of the valve to increase the flow of the overflow liquid; manually adjust the opening of the valve to decrease the flow of the overflow liquid...
