Device for detecting metal elements in atmospheric waste gas particles

Abstract

The invention discloses a device for detecting metal elements in atmospheric waste gas particles. The device comprises a shell, an inner box is arranged in the shell, a second connecting piece is fixedly connected to the bottom of the outer surface of the inner box, first connecting pieces are fixedly and symmetrically connected to the bottom of the interior of the shell, first connecting rods arerotatably connected to the outer surfaces of the first connecting pieces, and second connecting blocks are rotatably connected to the other ends of the first connecting rods. According to the invention, a hydraulic cylinder pushes two first connecting blocks to drive two second connecting rods to rotate and the two second connecting rods rotate to drive the two first connecting rods to rotate, sothat the inner box is supported; the device is pushed out of the shell, a motor rotates to drive a lead screw to rotate, so that a display screen is supported; and the device can be closed through atop cover and thus the air is isolated, so that the device is prevented from being polluted before use and thus the detection effect is prevented from being reduced.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a device for detecting metal elements in atmospheric waste gas particles. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. It is mainly caused by human factors such as mining, exhaust gas discharge, sewage irrigation and the use of products with heavy metals exceeding the standard. Heavy metals that exist in various chemical states or chemical forms will persist, accumulate and migrate after entering the environment or ecosystem, causing harm. For example, lead emitted from automobile exhaust enters the environment through atmospheric diffusion and other processes, resulting in The concentration has been significantly increased, resulting in the absorption of lead in the modern human body about 100 times higher than that of primitive people, which has damaged human health.

Heavy metals that exist in various chemical states or chemical forms will persist, accumulate and migrate after entering the environment or ecosystem, causing harm. For example, lead emitted from automobile exhaust enters the environment through atmospheric diffusion and other processes, resulting in The concentration has been significantly increased, resulting in the absorption of lead in the modern human body about 100 times higher than that of primitive people, which has damaged human health.

[0003] Existing devices for detecting metal elements in atmospheric waste gas particles have complex structures and difficult operations. Due to the lack of protective facilities, users use them in an improper way, or they are easy to drop when taking them, causing damage to the equipment, and The existing device is in an exposed state, which is easily contaminated and affects the test results
