Abstract

The invention relates to an automatic filter device and method for measuring free silica, and belongs to the technical field of workplace air detection and inspection. The device comprises a filter box, a liquid-gas dual-purpose vacuum pump and a control device; one side of the filter box is fixedly connected with the control device and the other side of the filter box is connected with the liquid-gas dual-purpose vacuum pump; the filter box comprises a box body, a box cover, a solution pipe, a metal thin tube, a rotary knob, a glass funnel and a metal pipe; a hose, a pressure gauge, a vacuumpump switch and a pressure regulating button are arranged on the liquid-gas dual-purpose vacuum pump; and the control device comprises a control panel, a hydrochloric acid solution inlet, a hydrochloric acid solution tank, a water inlet and a hot water tank body. The device is capable of automatically rinsing the free silica contents and treating samples in large quantities, thereby saving the cost, reducing the manpower, shortening the treatment time, improving the work efficiency, avoiding the operation errors, improving the accuracy and then improving the economic benefit of detection mechanisms.

Description

technical field [0001] The invention belongs to the technical field of air detection and inspection in workplaces, and in particular relates to an automatic filter device for measuring free silicon dioxide in workplaces. Background technique [0002] In the production process of the electric power and coal industry, there are mainly occupational disease hazards such as silica dust, coal dust, asbestos dust, and cement dust. It is very harmful to the human body and can cause necrosis of lung macrophages, resulting in pulmonary fibrosis, which is the main cause of pneumoconiosis. The content of free silica is the main index to evaluate the hazardous nature of dust. The dust hygiene standards of most countries and organizations are based on the amount of free silica in the deposited dust as the qualitative of the dust, and then judge whether the operation meets the requirements according to the occupational exposure limit. It is very common to measure the content of free silic...
