Description
Technical field
The utility model is related to material moisture detection field, and in particular to a kind of bulk material moisture on-line detection means and
Its detection method.
Background technology
In metallurgy industry, it is necessary first to the moisture in supplied materials is accurately detected, then controlled according to water content detection value
Material amount of water processed so that material moisture is maintained at during subsequent technique in a rational scope.The reality of material moisture
When detection the yield and quality and energy consumption index of final products are influenceed very big, only quick and precisely detect the moisture of material, ability
Accurate control is realized, and can largely reduce hand labor, improves production efficiency.As can be seen here, to original supplied materials
Moisture is used for quickly detecting analysis, and realizes that Automated condtrol is the key technology of metallurgy industry.
In existing metallurgy industry, original supplied materials moisture is usually manual sampling, send laboratory to be tested and analyzed, moisture inspection
Survey and detected using loss on drying, because can not accurately detect online, can not realize and automatically control, and testing result is seriously stagnant
Afterwards, the reduction of production efficiency is caused.In terms of water content detection, the mode of on-line checking typically uses infrared moisture meter and Microwave Water
Divide instrument etc. to be detected, belong to non-contact type measuring device, existing subject matter is that measurement is inaccurate, and cost is high, equipment
Maintenance trouble and difficulty complicated, therefore that moisture can be caused to control, further result in the shakiness of yield and quality index and energy consumption
It is fixed.
The U of Publication No. CN 201607382, publication date are on October 13rd, 2010, and entitled " one kind is used to detect material
The patent document of the device of moisture " discloses a kind of determination of moisture method, and this method uses by using the principle of microwave drying

Supplied materials is used for quickly detecting analysis, with Instructing manufacture, especially as materials such as original iron ore powder, coke powder and coal dusts, often changes a collection of
The secondary moisture for just needing to detect its supplied materials, the method currently used for detecting material moisture is mainly manual sampling, delivers to laboratory
Tested and analyzed, water content detection is mainly weighting method after dried, can also use infrared and microwave moisture instrument on-line checking, still
Measurement is inaccurate, and precision is not high.Long the time required to other manual sampling detection and analysis, human cost is high.With metallurgy industry pair
The raising of production automation level requirement, and the further reinforcement of intelligence manufacture theory, manual sampling detect the moisture of material
Can not meet the needs of highly efficient and productive and high automated production.
Found by studying, water is as a kind of polar molecule, and very strong with the coupling ability of microwave, water-containing materials exist
Under microwave action, it is possible to achieve rapid draing, realize the removing of moisture.Result of study shows, to common magnetite concentrate material
When carrying out microwave drying experiment, under the conditions of 1000W microwave power, inventory is fewer, and drying is faster, for 20g magnet essence
Mineral material, when microwave power 1000W, material moisture 8.6%, dry 30s cans and realize dehydration completely, 30g materials need
40s, 40g material then need 50s.As can be seen here, microwave can realize the rapid draing of material.
