Safety detection device to conveniently detect particle density in aluminum powder shop

Abstract

The purpose of the present invention is to solve the problem that the existing detection equipment is inconvenient to operate and carry, and discloses a safety detection device for detecting the particle density of the aluminum powder workshop, including an air duct, a fixed block, a sleeve, a blower, Through pipe, positioning block, rotating shaft, first filter screen and second filter screen, the lower side of the fixed block is welded with a connecting plate, the internal thread of the sleeve is fitted with a screw, and the lower end of the screw is fixedly equipped with a bracelet. A fixing frame is welded between the blower and the air guide pipe, a baffle is fixedly installed between the lower middle part of the duct and the fixed block, a fastening screw is installed between the rotating shaft and the positioning block, and the outer end of the rotating shaft Fixed installation with fixed plate. The present invention facilitates the detection of particle densities at different positions in the aluminum powder workshop through the cooperation of the bracelet and the screw, and uses the first filter screen and the second filter screen to facilitate the detection of particle densities of different sizes in the same area, and the structure Simple and worth promoting.

Description

technical field [0001] The invention relates to the field of aluminum powder processing, in particular to a safety detection device for conveniently detecting particle density in an aluminum powder workshop. Background technique [0002] Dust refers to solid particles suspended in the air. It is customary to have many names for dust, such as dust, dust, smoke, mine dust, sand dust, powder, etc. According to the International Organization for Standardization, solid suspended matter with a particle size of less than 75 μm is defined as dust. The existence of dust in the atmosphere is to keep the earth One of the main causes of temperature, too much or too little dust in the atmosphere will have a disastrous impact on the environment, but in life and work, productive dust is the natural enemy of human health and the main cause of various diseases. Specifically, in the aluminum powder production workshop, a large amount of free dust particles are often produced during the produ...

It is customary to have many names for dust, such as dust, dust, smoke, mine dust, sand dust, powder, etc. According to the International Organization for Standardization, solid suspended matter with a particle size of less than 75 μm is defined as dust. The existence of dust in the atmosphere is to keep the earth One of the main causes of temperature, too much or too little dust in the atmosphere will have a disastrous impact on the environment, but in life and work, productive dust is the natural enemy of human health and the main cause of various diseases. Specifically, in the aluminum powder production workshop, a large amount of free dust particles are often produced during the production process. If this kind of dust is not treated in a timely and effective manner, and the operators are in this working environment for a long time, it will often induce A large number of occupational diseases such as pneumoconiosis

[0003] In the aluminum powder workshop, it is necessary to detect the particle density of the aluminum powder workshop to determine the density of the particles and whether they are harmful to the human body. When detecting the particle density, some existing methods use infrared searchlights to detect the aluminum powder. The particle density in the workshop is tested. Such equipment is expensive to manufacture and is easily affected by external factors such as light, thereby affecting the detection effect. Some use sound waves for detection, which requires complicated operations and is a waste of time. When testing the particle density in the workshop, it is inconvenient to detect particles of different sizes, so that it is inconvenient to quickly detect the density of particles that are harmful to the human body. Some devices are large in size and inconvenient to carry, and it is inconvenient to detect aluminum Different locations in the powder workshop
