Embodiment Construction
[0017] Such as figure 1 as shown,
[0018] 1. The set value SP of the flocculant addition amount in the weak magnetic tailings concentration pool is 6m 3 / h, the measured value PV of flocculant addition is 6.4m 3 / h, the measured value PV is subtracted from the set value SP, and the deviation ▽ of the amount of flocculant added is 0.4m 3 / h.
[0019] 2. According to the maximum measured value PV max is 7m 3 / h, get the maximum deviation
[0020] ▽ max =PV max -SP=1m 3 / h. The area 0~▽max is divided into D1, T1, D2, T2, D3, T3, D4, T4, D5, and T5 areas sequentially from the left end 0. Among them, T1, T2, T3, T4, and T5 are named regulation areas; D1, D2, D3, D4, and D5 are named waiting areas.
[0021] Relationship between regions: the intersection of every two adjacent regions is 0, that is, D1∩T1=T1∩D2=D2∩T2=T2∩D3=D3∩T3=T3∩D4=D4∩T4=T4∩D5=D5∩ T5=0. The union of all regions is ▽max, that is, D1UT1UD2UT2UD3UT3UD4UT4UD5UT5=▽max. Generally, the lengths of areas D1, ...

Provided is a method for adjusting adding amount of a flocculating agent for a flux weakening tailing concentration basin. The range of the deviation between the measured value of the adding amount of the flocculating agent and a set value is divided into a waiting area and an adjusting area, the rotating speed of a feeding frequency converter remains unchanged if the deviation is in the waiting area, and corresponding adjustment is carried out on the feeding frequency converter if the deviation is in the adjusting area, wherein the rotating speed of the feeding frequency converter is reduced if the deviation delta of the adding amount of the flocculating agent is larger than zero, and the rotating speed of the feeding frequency converter is increased if the deviation delta of the adding amount of the flocculating agent is smaller than zero. According to the method for adjusting the adding amount of the flocculating agent for the flux weakening tailing concentration basin, the problem that the deviation between the adding amount of the flocculating agent and the required value of the production technology is large in fluctuation and cannot be stabilized in an allowed range when the adding amount of the flocculating agent for the flux weakening tailing concentration basin is adjusted is solved, and therefore stabilized production of the flux weakening tailing concentration basin is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of adjustment, and is mainly used for adjusting the addition amount of flocculant in a weak magnetic tailing concentration pool in the beneficiation link of metallurgical mines. Background technique [0002] Whether the deviation between the amount of flocculant added and the set value is stable within an allowable range during the production of the weak magnetic tailings concentration pool in the metallurgical mine beneficiation process has a great influence on the stable production of the weak magnetic tailings concentration pool. [0003] At present, the adjustment of the amount of flocculant added in the weak magnetic tailings thickening tank generally adopts manual and automatic adjustment methods. [0004] The manual method is based on manual observation of the change of flocculant addition amount displayed in real time on the computer operation station to operate the speed of the feeding frequency con...
