Full automatic caking index determinator

Abstract

The invention relates to a full automatic caking index determinator which comprises a pedestal; a rotary drum shelf and a balance are disposed on the pedestal; a rotary drum is disposed on the rotary drum shelf; the rotary drum is provided with a sliding door on a circumferential surface, and a sliding door control assembly for controlling the opening and closing of the sliding door; the determinator also comprises a dust collector, a pipeline connected with an air inlet of the dust collector, a sample container and a rotation mechanism for driving the rotation of the sample container; the rotation mechanism is disposed at a weighing position of the balance; the sample container is disposed at a sample inversion position above the rotary drum, is disposed at the middle part of the pipeline and is communicated with the pipeline; gaps are left between the pipeline and the two ends of the sample container communicated with the pipeline; an air outlet of the sample container is provided with a screen mesh; a sample receiving container is disposed at a sample receiving position below the rotary drum, and is communicated with the air inlet at the end of the pipeline. The invention provides the full automatic caking index determinator which can complete the determination work automatically, and can combine three procedures of sampling, screening, and weighing into one.

Description

Technical field [0001] The invention relates to an automatic adhesion index measuring instrument. Background technique [0002] According to the National Standard UDC622.22 of the People’s Republic of China, the determination of bituminous coal cohesive index is to test the strength of the coke in a drum of a certain specification. The abrasion resistance of the coke, that is, the resistance to destruction, is used to express the adhesion of the test coal sample. Knot ability. The specific operation is to put the coke block into the rotating drum and conduct the first rotating drum test. After the rotating drum test, the coke block is sieved with a 1mm round hole sieve, and then the weight of the sieve is weighed, and then put into The drum performs the second drum test, repeats the screening and weighing operations, and then calculates the bituminous coal cohesive index according to the relevant formula. Each drum test is 5min, 250 revolutions, and the weight is accurately wei...

AI Technical Summary

Problems solved by technology

[0003] At present, manual operation is used for the determination of bituminous coal cohesion index. In the actual measurement operation process, the operation procedure is complicated due to two processes of entering the coke into the drum, rotating the drum, exiting the drum, screening, and weighing. , and the measurement data is easily affected by human factors, and does not meet the needs of modern technological development
