Abstract

The invention provides an automatic sample introduction device used for a rock pyrolysis apparatus. The automatic sample introduction device comprises crucible mechanisms, a sample box, a sample separating mechanism, a carrying-on mechanism, a sample transmitting mechanism and a sample introduction mechanism, wherein multiple crucible mechanisms are contained in the sample box; each crucible mechanism is used for placing and containing a to-be-analyzed sample; the sample separating mechanism is used for enabling the crucible mechanisms in the sample box to be transmitted one by one; the carrying-on mechanism is used for carrying on the crucible mechanisms transmitted by the sample separating mechanism, so that multiple crucible mechanisms can be arranged on the sample transmitting mechanism in a transmitting direction of the sample transmitting mechanism; the sample transmitting mechanism is sequentially divided into a pyrolysis region and an oxidation region in the transmitting direction; the sample transmitting mechanism is used for enabling each crucible mechanism to be sequentially transmitted to the pyrolysis region and the oxidation region; and the sample introduction mechanism is used for enabling the crucible mechanisms in the pyrolysis region to enter a pyrolysis furnace and the crucible mechanisms in the oxidation region to enter an oxidation furnace. The automatic sample introduction device provided by the invention can improve working efficiency and avoid man-made influence.

Description

technical field [0001] The present application relates to the field of rock pyrolysis equipment, in particular to an automatic sampling device for a rock pyrolysis instrument. Background technique [0002] Pyrolysis analysis of source rocks is the basic analysis and evaluation method of source rocks. At present, it is only necessary to use a rock pyrolysis instrument for pyrolysis analysis of source rocks. Rock pyrolysis instrument includes pyrolysis furnace and oxidation furnace. When in use, the first choice is to place the dry rock powder in the stainless steel crucible, and then send the crucible into the pyrolysis furnace through the sample rod, and the organic matter in the rock is converted into hydrocarbons or oxidized into carbon dioxide through the temperature program, and the generated hydrocarbons The hydrogen flame ionization detector is used for detection, and the carbon monoxide and carbon dioxide generated by the pyrolysis of organic matter and the residual...
