Description
Technical field
The present invention is mainly concerned with the surveying instrument field analyzing combustible ash content composition, refers in particular to cigarette pit ash ATE (automatic test equipment).
Background technology
Ash content is the material reducing Coal Quality, under the various occasions of coal processing and utilization, all bring injurious effects, and therefore measuring ash content in coal has important meaning for the quality and processing and utilization aspect correctly evaluating coal.
During Standard ash test, need to weigh 1g air-dried sample, put into the muffle furnace 30 minutes of about 500 DEG C, and then put into the muffle furnace insulation 30 minutes of about 815 DEG C, fire constant mass.In conventional art, need employing two high temperature Muffle furnaces just can carry out ash test, and need a large amount of manual processing links, traditional ash content is measured, and labour intensity is large, inefficiency, can not adapt to the requirement of industry spot on-line analysis.In prior art, there is a lot of automation equipment for ash test, instead of the pure manual mode of operation of traditional instrument.The most key technology of existing automation equipment have employed a muffle furnace exactly, first sample is put into the muffle furnace of about 500 DEG C, after about 30 minutes, whole muffle furnace is incubated 30 minutes to 815 DEG C, fires constant mass.Although existing ash test have employed a muffle furnace and just achieves, but also existing defects: at one time, a warm area is only had in trial furnace, therefore ash test must be carried out in batch: before a upper ash test completes, the test of next coal sample cannot be carried out, namely cannot realize the streamline ash test of coal sample.
Summary of the invention
The technical problem to be solved in the present invention is: for the technical matters of " asher only has a warm area, cannot carry out continuity test ", the invention provides cigarette pit ash ATE (automatic test equipment), pit ash test can be carried out continuously, improve work efficiency.
For solving the problems of the technologies described above, the solution that the present invention proposes is: cigarette pit ash ATE (automatic test equipment), is characterized in that: it comprises inner lining of furnace, be placed on the furnace top cover on inner lining of furnace top, A district ceramic pipe and B district ceramic pipe, the A district thermopair measuring stove A district and stove B district temperature respectively and the B district thermopair be installed on furnace top cover, be arranged at inner lining of furnace outside air heat-insulation layer, turntable mounting, the rotating disk be arranged on turntable mounting for insulation; The periphery of described rotating disk is provided with on 20 equally distributed crucible poles, described 20 crucible poles and respectively placed an ash content crucible; Described inner lining of furnace installing is with on the drop-bottom of center drilling, and described crucible pole can be rotated in the center pit of drop-bottom around the axis of inner lining of furnace; The upper end of universal stage support is connected with described drop-bottom, and universal stage pedestal lower end is fixed on U-steel frame, and described universal stage mid-stent is equiped with electric rotary table.
Described inner lining of furnace is divided into A district inner lining of furnace and B district inner lining of furnace, the closed region that A district inner lining of furnace and furnace top cover form constitutes the warm area A of trial furnace in the present invention, and the closed region that B district inner lining of furnace and furnace top cover form constitutes the warm area B of trial furnace in the present invention; Being equiped with A district resistance wire inside described A district inner lining of furnace, for heating the temperature in A district, being equiped with B district resistance wire inside its B district inner lining of furnace, for heating the temperature in B district; Described inner lining of furnace is provided with fire door, puts into or take out the passage of ash content crucible.
Described crucible pole is provided with circular groove, and during test, ash content crucible is placed on circular groove, can not topple over when guaranteeing that ash content crucible rotates in stove; Being provided with rotating disk step in the middle part of described rotating disk for being placed in turntable mounting, being provided with turntable shaft bottom described rotating disk, described turntable shaft is connected with electric rotary table by shaft coupling.
Compared with prior art, the invention has the advantages that: asher of the present invention has two warm areas: about 815 DEG C of about 500 DEG C of high-temperature region A, high-temperature region B.Each coal sample enters from first fire door, and rotating disk half is in the A of high-temperature region, and second half is in the B of high-temperature region, and every 3 minutes dial rotation 1 lattice, after 60 minutes, coal sample turned to fire door place and takes out.It can thus be appreciated that no matter whether have the coal sample tested in asher, new coal sample still can enter in fire door, thus ensure that the pipeline function of ash test, improves work efficiency.
