Rotatable experiment table

Abstract

The invention discloses a rotatable experiment table. The experiment table comprises a rotating table used for bearing experiment instruments, a fixed table used for supporting the rotating table and a driving device, the fixed table is provided with a groove used for containing the rotating table, the driving device is connected with the rotating table so as to drive the rotating table to rotate in the groove, the table top of the fixed table is flush with the table top of the rotating table, and the fixed table and the rotating table are detachably connected. By using the rotatable experiment table provided by the invention, the convenience of maintenance and internal cleaning of a coal quality test experiment instrument can be effectively improved, the labor intensity of operators is reduced, and the experiment table is simple in structure, convenient to use and capable of being popularized and used.

Description

technical field [0001] The invention relates to the technical field of coal quality testing, in particular to a rotatable test bench. Background technique [0002] In the prior art, coal quality testing is an extremely important task in electric power and coal industries. Coal combustion analysis items generally include total moisture, air analysis, calorific value, element analysis and other items. The test temperature of most of the coal testing items is around 800-1300°C, and the instrument is operated in a high temperature environment for a long time, which is prone to instrument failure, and a large amount of smoke and coal dust will be generated during the coal quality testing operation. , easy to fall inside the instrument, difficult to clean from the front of the instrument. [0003] Most of these instruments are large in size and heavy in weight, and the internal structure design of the instrument is compact. When the instrument breaks down and needs to be repaired...

AI Technical Summary

Problems solved by technology

The test temperature of most of the coal testing items is around 800-1300°C, and the instrument is operated in a high temperature environment for a long time, which is prone to instrument failure, and a large amount of smoke and coal dust will be generated during the coal quality testing operation. , easy to fall inside the instrument, difficult to clean from the front of the instrument

[0003] Most of these instruments are large in size and heavy in weight, and the internal structure design of the instrument is compact. When the instrument breaks down and needs to be repaired, it is difficult for the operator to move the instrument. Moreover, due to the needs of ventilation and smoke exhaust, these instruments are generally Placed against a wall, making it difficult for the operator to maintain or access parts on the back and sides of the instrument

Moreover, most of the test benches for coal quality testing are fixed ones, and most of them are made of cement or customized chemical test benches. These fixed bench tops only consider the influence of factors such as stability and anti-corrosion. Instrument maintenance and internal cleaning operations
