Shearing device for automatic fluoride tester

Abstract

The invention discloses a shearing device for an automatic fluoride tester. The shearing device for the automatic fluoride tester comprises a machine box and a controller, a membrane containing plateis arranged in the machine box, a compactor, a circle cutter located on the inner side of the compactor and a mold pushing plate located on the inner side of the circle cutter are sequentially arranged right above the membrane containing plate, the top ends of the compactor, the circle cutter and the mold pushing plate are driven to ascend and descend through a driving mechanism, and the controlled end of the driving mechanism is connected to the output end of the controller; a circular leakage hole matched with the circle cutter is formed in the membrane containing plate; and a paper shredding mechanism is arranged below the membrane containing plate, a discharging port is formed in the bottom end of the paper shredding mechanism, and the controlled end of the paper shredding mechanism isconnected to the output end of the controller. According to the shearing device, the continuous shearing of the filter membrane can be realized under the condition of no manual guarding, and the paper shredding mechanism is arranged below the membrane containing plate, so that the filter membrane can be shredded into uniform fragments meeting the standard after being cut into circles.

Description

technical field [0001] The invention relates to the technical field of fluoride detection devices, in particular to a shearing device for an automatic fluoride detector. Background technique [0002] There are two types of fluoride in the ambient air: gaseous fluorine and dusty fluorine. The gaseous fluorine is mainly hydrogen fluoride, and the fluorine-containing dust is mainly cryolite, fluorite, aluminum fluoride and phospholime. The pollution mainly comes from electrolytic aluminum plants, phosphate fertilizer plants and Gases and dusts emitted or escaped from cryolite factories, etc. Human hydrogen fluoride 400 ~ 430mg / m 3 High concentrations can cause acute poisoning and death. Long-term inhalation of low-concentration fluorine and its compound gas and dust can affect the normal physiological functions of various tissues and organs, and even cause chronic fluorosis and skeletal fluorosis. Therefore, accurate determination of fluorine in the ambient air Pollution is v...

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to provide a shearing device for an automatic fluoride measuring instrument to solve the problem that the size of the filter membrane cut by direct shearing with scissors is not standardized, it is easy to cause artificial pollution, and it cannot realize automatic unmanned The problem of on-duty, so that the filter membrane can be evenly crushed, so as to improve the extraction efficiency of fluoride in the later stage, and at the same time avoid the influence of human factors, and realize continuous shearing of the filter membrane without manual guarding
