Description

An On-line Automatic Moisture Measurement System

technical field

The invention relates to the technical field of moisture measurement, in particular to an online automatic moisture measurement system for detecting moisture in a sample.

Background technique

The moisture analyzer is a commonly used device in the field of sample preparation, including functions such as weighing, drying, and data calculation. Through weighing, drying, and mass change calculation, the moisture content of the sample can be accurately measured. However, most of the sampling of the total moisture sample of this equipment is manually stirred in the laboratory, manually sampled, and then weighed. After sampling, it is placed in a moisture analyzer to be accurately weighed, dried, and then weighed to complete the calculation of the total moisture content. Determination. Therefore, it is not yet possible to produce an assembly line for sample preparation, so that the moisture content can be measured directly on-line after the full water sample is obtained. Instead, after the full water sample is obtained, the moisture content can be measured manually in the laboratory.

Based on this, the application number of the applicant of the present invention is 201510434035.0 Patent Application for Invention, which discloses an online automatic moisture measurement system. The online automatic moisture measurement system has a closed space, and the closed space is divided into an incoming material area by an isolation device. and the measurement area, a sampling device for sampling from the production line is provided in the incoming material area, and a discarding device for containing waste after sampling is provided. Device, sampling device and measuring device transport tray robot device. Wherein, the sampling device is a belt conveyor for conveying full water samples online, a shrinking machine for sampling on the belt conveyor, and a feeding device for transporting the obtained samples to the tray after sampling. It can be seen that there are following problems in this online moisture determination system:

First, it can only obtain samples, and cannot obtain samples with standard weights according to the standard weights of national standard moisture determination samples. That is, the online moisture measurement system cannot obtain a full moisture sample of a predetermined weight.

Second, the existing online automatic moisture measurement system divides the device into two areas, one is the measurement area and the incoming material area, to ensure the cleanliness of the measurement area and not be polluted by the incoming material area, but the incoming area The sampling device consists of a belt conveyor, a shrinking machine and a feeding device. These devices cannot be cleaned thoroughly. Therefore, they are easy to mix with the previous sample, which cannot guarantee the purity of the incoming sample itself.

Third, the full water sample is conveyed on the belt conveyor. In order to obtain a uniform sample, the shrinking machine needs to flatten the sample. In this way, before the sample is obtained, that is, during the transportation and sampling process, the sample will lose moisture.

Fourth, due to the need to separate the material area and the measurement area, a separation device needs to be added. The sampling device and the discarding device are all set in the incoming material area, while the measurement device, the tray removal device and the manipulator are located in the test area, so that the manipulator needs It moves in the measurement area and needs to extend to the incoming material area to take samples. This arrangement increases the space of the equipment, makes the equipment occupy a larger area, and adds isolation devices and switch isolation devices, which makes the structure more complicated.

Fifth, the manipulator of the online moisture measurement system will take the tray from the tray removal device and extend it out of the measurement area to enter the incoming material area, and receive the samples given by the sampling device and the unloading device and send them directly to the moisture analyzer in the measurement area for measurement . Therefore, the sample is not flattened, so that it is not easy to obtain uniform drying when drying in the moisture analyzer, and it will also increase the drying time, thereby reducing production efficiency.
