Abstract
The utility model discloses an arrangement method for a backflow pipe of a pipeline pump with a bypass valve block, wherein two parallel pipelines are arranged in the backflow pipe from a settling chamber to a mixing chamber and are respectively provided with two manual valves; an electric regulating valve is connected between the two manual valves on one pipeline, and a pipeline pump is connected between the two manual valves on the other pipeline. The requirement on the backflow quantity of the technique is realized through the forced backflow of the pipeline pump, and simultaneously, the normal natural backflow control means can be realized, so that the backflow quantities of the organic phase and the water phase satisfy the technical control requirements, the conditions of the extraction process are optimized and the extraction efficiency is efficiently improved.
Description
Technical field
The utility model relates to the extraction equipment of copper extraction process, particularly relates to a kind of pipeline mounted pump reflow pipe stringing mode with the bypass valve group.
Background technique
Organic facies and aqueous-phase reflux are the key means of extraction process control in the copper extraction process, therefore need to control different organic facies and aqueous-phase reflux amount to different feed liquid situation.Common adjusting is the natural potential difference that is utilized between the organic facies of clarifying chamber and water and the mixing chamber; Pump suction force that forms through the static pressure head between clarifying chamber and the mixing chamber, mixing chamber stirrer and reflow pipe gravity flow realize, utilize the valve regulated flow size on the reflow pipe.But because the pump suction force that static pressure head and mixing chamber stirrer form is limited, the reflow pipe flow velocity is restricted, so the flow of reflow pipe can not be too big, so traditional approach can't satisfy the operating mode that requires big capacity of reflux.
Summary of the invention
The purpose of the utility model is to provide a kind of stringing mode of controlling organic facies and aqueous-phase reflux; When the pump suction force of static pressure head mixing chamber stirrer formation is not enough to satisfy big capacity of reflux; Through the flow of pipeline mounted pump change reflow pipe, satisfy the operating mode demand of big capacity of reflux.
For realizing above-mentioned purpose, the utility model is taked following technological scheme, a kind of pipeline mounted pump reflow pipe stringing mode with the bypass valve group; It is characterized in that; In the reflux line of mixing chamber, be provided with two pipelines arranged side by side in the clarifying chamber, two manually operated valves are installed on two pipelines respectively; Wherein be connected with electric control valve between two manually operated valves of a pipeline, be connected with pipeline mounted pump between two manually operated valves of another pipeline.
The utility model is realized the requirement of technology capacity of reflux through the forced refluence of pipeline mounted pump; Also can realize simultaneously the natural back flow control device used always; Make organic facies and aqueous-phase reflux amount satisfy the technology controlling and process requirement, optimize the extraction process condition, effectively improve extraction efficiency.
Description of drawings
Fig. 1 is a kind of pipeline mounted pump reflow pipe stringing mode structural representation with the bypass valve group of the utility model;
Among the figure: 1. manually operated valve, 2. electric control valve, 3. pipeline mounted pump.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, referring to accompanying drawing 1, a kind of pipeline mounted pump reflow pipe stringing mode with the bypass valve group; It is characterized in that; In the reflux line of mixing chamber, be provided with two pipelines arranged side by side in the clarifying chamber, two manually operated valves 1 are installed on two pipelines respectively; Wherein 1 of two manually operated valve of a pipeline are connected with electric control valve 2, and 1 of two manually operated valve of another pipeline are connected with pipeline mounted pump 3.
Arrive under the little capacity of reflux situation of mixing chamber in the clarifying chamber; The pipeline that electric control valve 2 is equipped with in dependence can satisfy traffic requirement; At this moment, manually-operated gate 1 and pipeline mounted pump 3 Close Alls on the pipeline of pipeline mounted pump 3 are housed, the manually operated valve 1 on electric control valve 2 arms is opened with electric control valve 2.The pipeline mounted pump that pipeline mounted pump 3 adopts variable ratio frequency changer to regulate.
When pipeline flow can not meet the demands, the manually operated valve 1 that is equipped with on the pipeline of pipeline mounted pump 3 was all opened with pipeline mounted pump 3, and the manually operated valve 1 that is equipped with on the pipeline of electric control valve 2 cuts out with electric control valve 2.Pipeline mounted pump 3 is through the Frequency Converter Control flow.
The utility model can utilize the mode of time phasing to reduce investment outlay according to the engineering actual conditions.The operation initial stage can only be installed the bypass tube part of the valve group of being made up of electric control valve 2 and manually operated valve 1, and spare interface, and the later stage increases the system of band pipeline mounted pump 3 again.Transformation for existing engineering is suitable equally, need only need not implement the needs that local flow improvement can satisfy bigger capacity of reflux to existing pipeline to the big variation and the occupation of land of technological process.Therefore the transformation amount to existing production system is little, is suitable for the newly-built factory or the project of modernizing and expanding the existing factory.
