Description
Technical Field
The invention belongs to the technical field of mineral separation, relates to the technical field of fluid, slurry settling, concentration monitoring and fixed-point multi-position sampling at different liquid levels, and particularly relates to a device for sampling and monitoring slurry level and concentration of ore slurry.
Background
The fineness of the product of the ore grinding classification operation is closely related to the concentration, and the change of the concentration causes the change of the fineness. Therefore, the inspection and control of the concentration of the ore grinding grading operation are necessary, and the inspection and control of the concentration of the ore grinding grading operation can be helpful for improving the ore grinding efficiency and the grading index. The concentration of the ore pulp is checked by the concentrating mill and is generally measured by a concentration pot. The method comprises the following steps of (1) correcting the zero point of a platform scale (or a coarse balance), (2) checking whether the weight and the volume of an empty concentration kettle conform to a checked concentration kettle table, and (3) mining a slurry sample by using a sampling spoon according to sampling regulations, carefully pouring the sampled sample into the concentration kettle, slightly shaking the sampling spoon in the pouring process to prevent ore slurry from precipitating, and pouring all the ore slurry in the spoon into the kettle until the ore slurry flows out from an overflow port of the concentration kettle. The method comprises the steps of (1) sealing an overflow port by using a forefinger when the ore pulp at the overflow port stops flowing so as to prevent the ore pulp in a pot from flowing out, (4) wiping the outer wall of a concentration pot by using a cleaning cloth and weighing on a scale disc, (5) adding the total weight of the ore pulp into the pot, namely the ore pulp concentration can be checked on a concentration meter.
As the concentration is checked frequently, in order to meet the timely requirement of the adjustment process, the calculation work of measuring the concentration on site every time is saved, the operation is convenient, and the concentration can be adjusted in time. Concentration under a certain ore pulp weight is generally calculated by a concentrating pot with a certain volume and known weight according to the specific gravity of ore entering a mill. The method is characterized in that different ore pulp weights G are converted into different ore pulp concentrations R, and then a one-to-one corresponding table is made, which is commonly called an ore pulp concentration checking table. The existing mineral processing technology of industrial and mining enterprises has the difficulties of slurry settling height of slurry containing tanks, concentration monitoring and sampling:
(1) The existing liquid level and material level meters are difficult to monitor the slurry sedimentation height under the conditions of liquid level penetration and fluid concentration change, and instruments for realizing the slurry sedimentation height by special fluid pressure change have high price, poor reliability and high maintenance cost;
(2) The existing sampling method is difficult to realize that a slurry containing groove extracts a sedimentary slurry sample (samples);
(3) At present, no automatic monitoring device integrating pulp level, concentration and sampling in a pulp containing tank is available in the field of industrial and mining.
