Problems solved by technology

When the material conveyed on a belt is uncertain, it is difficult to automatically measure the water of different materials, and it is necessary to manually adjust the detection parameters of the moisture meter according to the change of the material on the belt. When the material changes frequently, it is difficult. Realize the online detection of moisture; the microwave method cannot accurately detect the moisture content in the core of the material
[0004] The detection equipment and theoretical schemes of the above methods are complicated, and sometimes professionals are required to solve them.

Embodiment 1

[0113] like Figure 1-3 , an absolute method on-line moisture detection system, which includes a box 1, an analysis and discharge device 2 located on the left side of the box 1, a running drying device 3 located on the right side of the box 1, and an analysis and discharge device 3. Sampling system 5 above device 2. The analyzing and discharging device 2 has a gripper 204 which is rotatable along the rotating mechanism 206 in the horizontal direction, and also has two workstations: a feeding position a and a weighing and discharging position b. The operation drying device 3 has a turntable 301, four chambers arranged on the turntable 301, a top cover 303 located on the upper part of the four chambers, and three microwave generators 304 arranged on the top cover 303, and also has four 1 station: the second station d, the third station e and the fourth station f are set in sequence in the counterclockwise direction close to the first station c of the analysis and discharge devi...

Embodiment 2

[0121] Example 1 is repeated, except that the operation drying device 3 further includes a second weighing device 307 disposed below the third station e and located at the lower part of the turntable 301 .

Embodiment 3

[0123] An absolute method on-line moisture detection method, using the moisture detection system in Embodiment 1, the method comprises the following steps:

[0124] 1) The first weighing device 203 located below the weighing and discharging level b weighs the weight of the sample container 201 after discharging (W 0 );

[0125] 2) The gripper 204 grasps the sample container 201 by lifting, and rotates the sample container 201 from the weighing and discharging position b to the feeding position a. Placed on the measuring platform 202, the feeding plate 501 receives the material from the belt blanking place of the belt conveyor and is driven by the moving shaft of the feeding plate driver 502 to recover, and the reclaiming baffle 503 scrapes off the material of the feeding plate 501, The sample material flows into the sample container 201 with the feeding funnel 4;

[0126] 3) The gripper 204 grasps the sample container 201 and rotates the sample container 201 from the feeding...

Abstract

The invention relates to an online water detection system by an absolute method. The system comprises a box body, an analyzing and discharging device located on one side in the box body and a transferring and drying device located on the other side in the box body, wherein the analyzing and discharging device is provided with a gripper which rotates along the center axis in the horizontal direction and is also provided with at least two stations: a receiving station and a weighing and discharging station; the transferring and drying device is provided with a rotary disc, four chambers arranged on the rotary disc, top covers located on the upper parts of the four chambers and micro generators arranged on the top covers as well as four stations: a first station, a second station, a third station and a fourth station. Openings are also formed in the upper parts, corresponding to the edge of the rotary disc, of the four chambers, and fixed sealing baffle plates are separately arranged onthe upper parts, corresponding to the edge of the rotary disc, of the second, third and fourth stations. The system can detect the true water content of a mixed material within a very short time, so that real-time online detection of water of the mixed material is achieved.

Description

technical field [0001] The invention relates to a material moisture detection device and method, in particular to an absolute method online moisture detection system (or detector) for mixed materials and a detection method thereof, belonging to the field of raw material preparation in metallurgical sintering and pelletizing industries. Background technique [0002] In the field of metallurgical sintering and pelletizing, a certain amount of moisture is generally required in the process of mixing materials to provide the necessary cohesion and adhesion for the formation of material pellets. This moisture includes a part of the moisture contained in the mineral material itself, and moisture will also be added during the mixing process, so that the various raw materials are uniformly mixed, which facilitates the pelletization and granulation of the material, and is conducive to more sufficient reaction in the subsequent process. If the amount of water is too low, the cohesivene...
