Full-automatic multi-disc constant-temperature constant-humidity precise weighing system

Abstract

The invention discloses a full-automatic multi-disc constant-temperature constant-humidity precise weighing system, which comprises a machine body. Two midfeathers are arranged on the machine body; and the two midfeathers divide the machine body into a left compartment, a middle compartment and a right compartment from the left to right. The left compartment and the right compartment are same in inner structure; the front portion of the left compartment is provided with a rotary code scanning device; the middle portion of the left compartment is provided with a short stroke mechanical fork device; the back portion of the left compartment is provided with a material mixing device; the front side of the right compartment is provided with a linear platform device; the middle portion of the right compartment is provided with a long stroke mechanical fork device; and the back side of the right compartment is provided with a weighing device. The system is simple in structure, novel in design, scientific and convenient, highly targeted and high in automation degree, and well solves the problem of weighing of suspended particulate samples in the atmosphere.

Description

technical field [0001] The invention relates to a fully automatic multi-disk constant temperature and humidity precision weighing system. Background technique [0002] With the continuous development of industry, the living environment of human beings has been destroyed, and the air pollution situation is severe. The suspended particles in the air not only affect the weather, but the inhalable particles also seriously endanger people's health. Suspended particulate matter in the atmosphere has become a major focus of attention. Inhalation in the atmosphere can cause human respiratory tract disease, lung function damage and other hazards. Most of the existing equipment used the membrane gravimetric method to detect the content of suspended particulate matter in the atmosphere. This method is to capture the particulate matter in the air on a filter membrane with a certain diameter of pores, and then weigh the mass of the filter membrane before and after sampling. The mass of...

Problems solved by technology

However, the existing weighing systems all have a single-chamber structure. Because the single-chamber structure often communicates with the outside air during the membrane conveying process, the constant temperature and humidity in the cabin cannot be guaranteed, which affects the subsequent weighing accuracy.

In addition, the single-chamber structure weighs a small quantity at a time, resulting in low work efficiency
