As shown in Figs. 1-3, a kind of hydrocarbon primary rock producing hydrocarbon thermal simulation reaction kettle collector of the present invention including reaction kettle 1 and takes
Depressed structure 2.The reaction kettle 1 includes autoclave body 11, clamping nut 12 and the sealed taper 13 being fixed on clamping nut.Wherein, it presses
Tight nut 12 is threadedly coupled with 11 upper end of autoclave body, and clamping nut 12 can make sealed taper 13 by autoclave body 11 after being connect with autoclave body 11
Opening sealing.
It is described depressed structure 2 is taken to include for place the autoclave body take gas chamber 21 and can be with gas chamber be taken to be tightly connected
Cavity top cover 22.Specifically, described take can be close by way of setting sealing ring 210 between gas chamber 21 and cavity top cover 22
Envelope.It takes gas chamber 21 cylinder, offers a through-hole at 22 center of cavity top cover, a screw rod 23 is installed on through-hole,
Sealing ring 24 is set on the screw rod body of rod, an outlet passageway 25 for running through screw rod is further opened on screw rod 23.The outlet leads to
The upper end in road 25 is connected by tracheae 26 with gas bomb 27 and vacuum pump 28 respectively, and valve is equipped on the tracheae of connection gas bomb
Door 291 is connected with valve 292 on the tracheae of connection vacuum pump.Card slot is offered on the top surface of the clamping nut 12
121, the lower end of the screw rod 23 is equipped with the protrusion 231 being mutually clamped with card slot.
Further, the inner bottom surface for taking gas chamber 21 is equipped with a square protruding 211, on 11 bottom surface of autoclave body
Equipped with the rectangular card slot 111 being mutually clamped with square protruding.It is so designed that, can be placed on reaction kettle stabilization and take gas chamber 21,
