Below provide and utilize described in the utility model pair of deckered stock chest Slurry Pipeline Transportation system to solve the method for some technical problems that conventionally run in existing Slurry Pipeline Transportation:
Elected factory produces different grade ore pulps as first while selecting factories and miness supply line A to provide low grade ore pulp, second to select factories and miness supply line B that high grade ore pulp is provided, by opening valve 1, throttle down 2, open valve 4, throttle down 3, thereby can allow high grade ore pulp enter the first deckered stock chest 100, allow low grade ore pulp enter the second deckered stock chest 200, thereby realize concentrating separating of the different grade concentrate of height, carried and carry out adequate preparation for pipeline classification.
If the first deckered stock chest 100 breaks down in normal course of operation, can not to enter in short-term ore deposit concentrated, by opening valve 2, throttle down 1, temporarily allow and select the high grade ore pulp that factories and miness supply line B provides to enter the second deckered stock chest 200 from second, and Hui Bitingxuan factory does not produce.If in like manner the second deckered stock chest breaks down, can not to enter in short-term ore deposit concentrated, by opening valve 3, throttle down 4, temporarily allow and select the low grade ore pulp that factories and miness supply line A provides to enter the first deckered stock chest 100 from first, and Hui Bitingxuan factory do not produce.
Elected factory yielding capacity strengthens, that running appears in deckered stock chest 100 or 200 is mixed, can carry out the respite heavier deckered stock chest of loading by the aperture of regulating valve 1,2,3,4 while running ore deposit, ensureing to make deckered stock chest overflow water qualified in the situation that of not affecting production as far as possible, as being 375t/h when the maximum processing capability of the first deckered stock chest, through second select that factories and miness supply line B provides select under factory ore deposit concentration by namely 1200m of the words of 25% calculation
3/ h, if be greater than 1200m
3/ h can suitably open valve 2, select the ore pulp that factories and miness supply line B provides to shunt a part by DN450 pipeline to the second deckered stock chest 200 by second, the aperture of valve 2 can contrast selects under factory ore deposit amount and deckered stock chest actual conditions to regulate, and is controlled between 10%--50%; In like manner this 300t/h of the maximum processing capability of the second deckered stock chest 200, through first select that factories and miness supply line A provides select under factory ore deposit concentration by namely 970m of the words of 25% calculation
3/ h, if be greater than 970m
3/ h can suitably open valve 3, allows first to select a part of ore deposit in factories and miness supply line A to be diverted to the first deckered stock chest 100 by DN350 pipeline, and the aperture of valve 3 can contrast selects under factory ore deposit amount and deckered stock chest actual conditions to regulate, and is controlled at 10%--50%.
In the time running into great overhauling project, for example the first deckered stock chest 100 is overhauled: be pumped into after stirring chest by the first underflow pump unit 21 and the first bypass line 23 at the high-concentration ore slurry that the first deckered stock chest 100 bottoms is met to pipeline conveying requirement, the interior remaining most of concentration of the first deckered stock chest 100 can be extracted in the second deckered stock chest 200 and again be concentrated by underflow pump by the second bypass line lower than 60% ore pulp and water, only need to start the underflow pump in the first underflow pump unit, open valve 6 simultaneously, throttle down 5, the interior remaining low density ore pulp of the first deckered stock chest 100 and water can be extracted in the second deckered stock chest 200.When in like manner the second deckered stock chest 200 will empty, also only need to start the second underflow pump unit, open valve 13, throttle down 14 can complete simultaneously.
The utility model is by arranging two deckered stock chests, and by arranging that various pipelines trend and related valve realized the cooperating pattern of two deckered stock chests, performance and the working efficiency of Slurry Pipeline Transportation system are greatly improved, providing two deckered stock chests is a kind of preferred versions on the utility model design basis, it can meet the user demand of current slurry pipeline system, but protection of the present utility model is not limited to this, those skilled in the art can arrange three or more deckered stock chests on the basis of the utility model innovation thinking, between these deckered stock chests with and and stirring chest between pipeline annexation and the above-mentioned preferred implementation of the application similar, within these distortion all fall into technological innovation scope of the present utility model, protection domain of the present utility model is as the criterion with the record of claims.
