Problems solved by technology

However, this technology can only be used for offline detection in the laboratory, and it is mainly aimed at the drying of large particle materials, which cannot meet the needs of online rapid detection
[0005] In the metallurgical industry, moisture detection of raw materials is often required. For example, due to the short change cycle of incoming materials during sintering production, fluctuations in physical and chemical properties such as moisture will have a very bad impact on subsequent sintering production. Therefore, rapid detection of incoming materials is required. Analysis to guide production, especially for materials such as raw iron ore powder, coke powder and coal powder, the moisture content of incoming materials needs to be tested every time a batch is changed. At present, the method used to detect the moisture content of materials is mainly manual sampling, which is sent to The laboratory conducts detection and analysis. Moisture detection is mainly based on drying and weighing methods. Infrared and microwave moisture meters can also be used for online detection, but the measurement is not accurate and the precision is not high.
In addition, the time required for manual sampling, detection and analysis is long and the labor cost is high
With the increasing requirements of the metallurgical industry for the level of production automation and the further strengthening of the concept of intelligent manufacturing, manual sampling to detect the moisture content of materials can no longer meet the needs of high-yield, high-efficiency and high-automation production

Embodiment approach

[0102] According to the second embodiment of the present invention, there is provided an online moisture detection method for bulk materials or an online moisture detection method for bulk materials using the above-mentioned moisture online detection device for bulk materials, the method comprising the following steps:

[0103] 1) The charging container (such as the charging box) 2 slides into the second area T2 under the push of the driving rod of the first linear motor 6 and weighs the unfilled container 2 through the first weighing device 3 weight (W 0 );

[0104] 2) extract (for example, use the manipulator 10 or the sampling driving device 11 to extract) material samples from the mixed materials from the bulk material mixing process and add the samples of the materials to be tested into the hopper 1, and the grabbed samples pass through The hopper 1 is dropped into a charging container (for example a charging box) 2 that has entered into the second zone T2;

[0105] 3) ...

Embodiment 1

[0129] Such as figure 1 , an on-line moisture detection device for bulk materials, the device includes four slideways, namely the first slideway L1, the second slideway L2, the third slideway L3 and the fourth slideway L4, the four slideways are sequentially Connected from end to end to form a square closed loop. On the chute of the closed circuit placed 8 magazines Kata 2. The first slide L1 is the feeding area, the second slide L2 is the microwave drying area, the third slide L3 is the detection area, and the fourth slide L4 is the discharge area.

[0130] Such as figure 2 , the first slideway L1 is divided into the first area T1, the second area T2 and the third area T3 as the station for feeding and first weighing. Wherein the third area T3 links to each other with the second slideway L2, and the first slideway L1 is provided with the first linear motor 6 at the end that links to each other with the fourth slideway L4, and the driving rod of the first linear motor 6 (...

Embodiment 2

[0136] Repeat embodiment 1, only the sampling equipment of this device is changed into sampling driving device 11, and sampling driving device 11 comprises the sampling plane 1101 that is positioned at front end, the sampling pipeline 1102 that is positioned at middle end and the sampling driving structure 1103 that is positioned at end, and sampling driving device 11 uses Grab the material and send it to hopper 1.

Abstract

The invention provides an online moisture detection device for a bulk material. The device includes four slideways which form a square closed loop, and multiple charging containers (2) are placed in the closed loop; a first slideway (L1) is a charging area, a second slideway (L2) is a microwave drying area, a third slideway (L3) is a detection area, a fourth slideway (L4) is a discharge area; eachslideway is provided with a linear motor with a driving bar, and the linear motors are used for pushing the charging containers (2) to slide from one position to a next position. The moisture of different types of the bulk material can be detected in real time, rapidly, online and accurately, and the measurement precision can reach the moisture measurement precision of a manual sampling, drying and weighting method.

Description

technical field [0001] The invention relates to the field of material moisture detection, in particular to an on-line moisture detection device for bulk materials and a detection method thereof. Background technique [0002] In the metallurgical industry, it is first necessary to accurately detect the moisture in the incoming material, and then control the amount of water added to the material according to the moisture detection value, so that the moisture content of the material can be kept within a reasonable range in the subsequent process. The real-time detection of material moisture has a great impact on the output quality and energy consumption indicators of the final product. Only by quickly and accurately detecting the moisture content of the material can precise control be achieved, and it can greatly reduce manual labor and improve production efficiency. It can be seen that the rapid detection and analysis of the original incoming material moisture and the realizat...
