Abstract

The invention relates to the analytical control of the composition of the raw materials and finished products of potash processing plants and can be used in the beneficiation of ferrous and non-ferrous metals. The purpose of the invention is to expand the functionality and increase the representativeness of samples of multicomponent joints. The goal is achieved by sequentially carrying out operations of sampling suspensions from pressure pipelines, pneumatic vacuum separation of its components into liquid and solid phases, alternately mashing into the capsules of the pneumatic tube both liquid and solid. phases, followed by washing and drying of the system devices after each of the specified pair of sample shipments. These operations are achieved by the fact that the automated system for investigating suspensions contains, in addition to the sampling device, an intermediate tank of the liquid metering device and control elements, a filtering device with a mechanism for unloading the solid phase into the capsule of the pneumomail and a packing nozzle for sequential loading into the capsules of the pneumomail both liquid and solid suspension phases. The use of an automated system in potash processing plants allows discrete samples of liquid and solid phases in an amount of up to 150 g to be automatically selected from the suspension stream in a quantity of up to 0.25 hours, packed into capsules of pneumatic mail and transported in three to six components. 1 il. sl С about 00 th 00 cl

Description

The invention relates to the analytical control of the composition of the raw materials and finished products of potash processing plants and can be used in the beneficiation of ferrous and non-ferrous metals.

The purpose of the invention is to expand the functionality and increase the representativeness of samples of multicomponent suspensions.

The drawing shows an automated suspension research system.

The automated system for investigating suspensions contains a sampler 1 with pipelines for supplying compressed air 2, water 3 and a path for the suspension of suspension 4, intermediate tank 5, filtering device 6 with mechanism 7, solid phase discharging and shut-off device 8, filling the nozzle 9, measuring tank 10 with pipelines supplying vacuum 11, compressed air 12 and water 13, paths for supplying filtrate 14 from a filtering device, dispensing filtrate 15 and draining excess filtrate and flushing water 16, a pneumatic mail system consisting of mechanics 17, capsules 18 and pneumatic routes 19. The suspension research system also contains a control device in the form of well-known microcontrollers or control computer complexes of an automated process control system.

Automated system operates as follows.

According to the appropriate commands of the control device, the sampler 1 takes a representative sample of the suspension from the discharge pipeline and passes through the path 4 into the intermediate tank 5, from where it is compressed with compressed air into the filtering device 6, which separates the suspension into liquid and solid phases. In the process of pneumatic vacuum separation, the liquid phase along the path 14 enters the tank 10, from where it is compressed through the packing nozzle 9 into the capsule 18 coupled to the nozzle via compressed air, and is sent along the pneumatic track 19 to the place of X-ray spectral analysis. After this, when the locking device 8 is opened, the solid phase mechanism is unloaded from the filter device 6 by the mechanism 7 through the filling nozzle 9 into the second capsule 18, previously joined to the nozzle, and sent for analysis.

After sending the second capsule with the solid phase of the suspension in the system, all the devices are alternately washed.

water and dry them with compressed air, as a result of which the system is prepared for re-sampling.

Using the research method

suspensions and the automated system that implements it allows us to significantly reduce the laboriousness of the work on the selection, initial preparation and delivery of samples for X-ray spectral analysis, which is

usually 2/3 of the labor intensity of all operations of analytical control of the composition of raw materials and enrichment products by classical methods, and a decrease in labor intensity of this value is achieved not less than 2 times.

In addition, efficiency is achieved

analytical control of the composition of raw materials and products of enrichment and process control allows to increase the extraction of useful components

processed ore and reduce the specific consumption of reagents.
