Titanium tetrachloride sampling bottle

Abstract

The invention relates to the technical field of sampling bottles, and specifically relates to a titanium tetrachloride sampling bottle. The titanium tetrachloride sampling bottle comprises a bottle body, a bottleneck, a sampling valve and a bottle cap, wherein the bottleneck is adhered to the top of the bottle body; the sampling valve is arranged on the bottleneck; an external thread is arranged on the outer surface of the bottleneck; and the bottle cap and bottleneck are in detachable threaded connection. The titanium tetrachloride sampling bottle also comprises a connector, wherein the connector is hollow and is a cylinder with two through ends, the inner surface of the connector is provided with an internal thread corresponding to the external thread of the bottleneck, and the connectorand the bottleneck are in detachable threaded connection; the bottle body is a transparent glass body, and the bottle body is internally vacuum. The titanium tetrachloride sampling bottle adopts a vacuum bottle body design, the air pressure inside the bottle body is prevented from being raised, titanium tetrachloride liquid an be collected successfully, and the sample validity of the collected titanium tetrachloride is higher; and the titanium tetrachloride sampling bottle adopts a connector design, can be quickly connected with a titanium tetrachloride pipeline, and is also convenient to detach.

Description

technical field [0001] The invention relates to the technical field of sampling bottles, in particular to a titanium tetrachloride sampling bottle. Background technique [0002] Titanium tetrachloride, or titanium(IV) chloride, is an inorganic compound with the chemical formula TiCl4. Titanium tetrachloride is an important intermediate in the production of titanium metal and its compounds. At room temperature, titanium tetrachloride is a colorless liquid and fumes in the air to form a mixture of titanium dioxide solids and hydrochloric acid droplets. In the production of refined titanium tetrachloride, in order to analyze the production process of each process, control process parameters, and provide a basis for guiding production, it is necessary to sample titanium tetrachloride. [0003] At present, domestic refined titanium tetrachloride manufacturers generally use a drainage tube and a sampling bottle to sample titanium tetrachloride. This sampling method will cause ti...

Problems solved by technology

[0003] At present, domestic refined titanium tetrachloride manufacturers generally use a drainage tube and a sampling bottle to sample titanium tetrachloride. This sampling method will cause titanium tetrachloride to contact with air and react, which will affect the sampling accuracy and affect Test results

The patent No.: CN201220715320.1 discloses a closed sampling device for the production of refined titanium tetrachloride. Although it prevents air from entering the sampling bottle, the inherent air in the sampling bottle will also affect the sampling accuracy. Inconvenient to install and remove
