Problems solved by technology

[0002] At present, the existing horizontal glass column sulfur and nitrogen analyzers on the market cannot realize automatic sampling or automatic sampling still requires manual participation. In order to solve this technical problem, it is necessary to develop automatic sampling for horizontal glass column sulfur and nitrogen analyzers. device
In addition, the samples in the prior art are atomized after being injected through the injection needle, and then burned. If the atomization can be performed first and then burned, the combustion can be made more complete, and the combustion process can be made faster and the efficiency can be improved. However, Setting the spray chamber separately requires improvement of the device

Abstract

The invention discloses a horizontal automatic sampling device for ultraviolet fluorescence sulfur, which comprises a sampling mechanism and a sample injection mechanism. The sampling mechanism comprises a base, a rotating disc, a plurality of sample bottles, a sampling needle and a sampling pipeline, a plurality of fixed clamping grooves are formed in the rotating disc, a plurality of sample bottles are respectively arranged in the fixed clamping grooves in a matched manner, the sampling needle is communicated with the sampling pipeline, and the sampling needle is driven by a stepping motor to vertically move up and down. The sample injection mechanism comprises a sample loop, a six-way valve, an emptying port, a negative pressure pump, a carrier gas inlet and a connecting mechanism, sixvalves of the six-way valve are respectively communicated with the sampling pipeline, one end of the sample loop, the carrier gas inlet, the connecting mechanism, the other end of the sample loop andthe emptying port, and the sample injection mechanism is communicated with a sulfur and nitrogen analyzer through the connecting mechanism. The device provided by the invention can realize automatic and horizontal sample injection on the basis of the existing manual equipment, and can improve the detection precision while improving the detection work efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical analysis. More specifically, the present invention relates to an automatic injection device for ultraviolet fluorescent sulfur levels. Background technique [0002] At present, the existing horizontal glass column sulfur and nitrogen analyzers on the market cannot realize automatic sampling or automatic sampling still requires manual participation. In order to solve this technical problem, it is necessary to develop automatic sampling for horizontal glass column sulfur and nitrogen analyzers. device. In addition, the samples in the prior art are atomized after being injected through the injection needle, and then burned. If the atomization can be performed first and then burned, the combustion can be made more complete, and the combustion process can be made faster and the efficiency can be improved. However, Setting the spray chamber separately requires improvement of the device. Therefore, o...
