Abstract

The invention discloses a multipath fluid distribution device comprising a plurality of ore pulp distribution boxes which are arranged in parallel. At least one steady flow sample box is arranged under the ore pulp distribution boxes; an ore feeding elbow is arranged above each ore pulp distribution box; an outlet of the ore feeding elbow is connected with a special rubber pipe; the output position of the special rubber pipe comprises a left position, a middle position and a right position; the special rubber pipe is connected with an output position control device; filter screens are arranged at the left sides in the ore pulp distribution boxes; fetching sample blades are arranged at the right sides of the ore pulp distribution boxes; the filter screens and the fetching sample blades respectively correspond to the left position and the right position of the output position of the special rubber pipe; the lower parts of the filter screens correspond to the steady flow sample boxes; sample discharge pipelines are arranged at the lower parts of the steady flow sample boxes; and ore discharge pipelines are arranged at the lower parts of the ore pulp distribution boxes and correspond to the middle position of the output position of the special rubber pipe. The invention can reasonably distribute multipath fluid before measuring an analyzer and meet the requirements of the analyzer for measuring the representativeness and the flow of each measuring point as well as a plurality of measuring points in sequence.

Description

technical field [0001] The invention relates to a fluid distribution measuring device in the ore dressing process, in particular to a multi-channel fluid distribution device. Background technique [0002] The on-line and real-time detection of the grade and particle size of minerals in the beneficiation process plays a very important role in guiding production, controlling product quality, and improving recovery. The measurement of the above indicators mostly adopts current-carrying concentrated measurement, that is, the method of measuring several measuring points by one analytical instrument requires a set of methods and devices for distributing samples from several measuring points. [0003] Most of the online analytical instruments in the prior art are for single-channel fluid measurement, or it is difficult to ensure the representativeness of the sample and the stable flow rate into the analytical instrument when the multi-channel fluid is distributed.
