Device capable of automatically detecting water content of slag micro powder

Abstract

The invention relates to a device capable of automatically detecting the water content of slag micro powder. The device comprises a workbench and a cover cap. A conveying belt is arranged on the workbench; a detection area is arranged on the conveying belt, a control device is arranged in the workbench, a weighing device is connected to a lower portion of the detection area, one end of the cover cap is hinged to an edge of the detection area, the cover cap is of a constant-temperature hollow structure with a downward movable opening, and the control device is connected with the weighing device. Compared with the prior art, the device capable of automatically detecting the water content of the slag micro powder has the advantages that the weighing device is arranged in a detection area of the conveying belt; the rotatable constant-temperature cover cap and a movable cover cap opening are used for weighing a sample and forming a closed drying space, and the control of each structure andthe calculation and display of experimental data are realized through the control device, so that the automatic detection of the water content of the slag micro powder is realized, and a large amountof manpower and material resources are saved.

Description

technical field [0001] The invention relates to a detection device, in particular to a device capable of automatically detecting the water content of slag fine powder. Background technique [0002] Slag is the industrial waste produced by iron and steel enterprises. Slag is a kind of industrial solid waste, which is the waste slag discharged from the blast furnace ironmaking process. The output varies with the smelting technology and the ore grade, and is generally 25% to 90% of the pig iron output. According to this, the annual output of slag in my country is estimated at About 60 million tons, slag is mainly used as a mixture of cement. The slag in building materials refers to the fine-grained glassy substance formed when the molten slag of blast furnace ironmaking has no time to crystallize when it is quenched. [0003] Slag fine powder is a product that grinds slag to a certain fineness. The main purpose is to mix in cement and add to commercial concrete to increase th...

Problems solved by technology

[0004] Slag micropowder is a new type of excellent building material, which has been used by more and more construction units in buildings, and slag micropowder has suitable performance is an important prerequisite for determining the quality of cement or concrete. Therefore, for slag powder Sampling and testing of fine powder is very necessary. The State Bureau of Technical Supervision issued the national standard document "Granulated Blast Furnace Slag Powder Used in Cement and Concrete" to control the quality of slag fine powder, and the requirements for water content of slag fine powder is less than 1%. However, most of the existing water content inspection devices are manual inspections, which consume a lot of manpower and material resources and have low detection efficiency, which is not conducive to the long-term development of enterprises.
