Embodiment Construction
[0017] like figure 1 , 2 As shown, the shale sample crushing and desorbing device of the present invention includes an iron frame 11, a limit plate 1, a core barrel 2, a hand wheel 4, a rack 7, a chip collecting barrel 10 and a cutter 12,
[0018] A panel is fixedly installed on the iron frame 11, and the limiting plate 1 is installed on the panel, and the effect is to limit the moving direction of the core storage barrel when adding rock core; the core storage barrel 2 is installed on the panel of the iron frame , The core barrel is a split type, including a fixed end and a movable end, and the fixed end and the movable end are connected by bolts 3 . The fixed end is fixed on the panel of the iron frame, the movable end is installed on the panel of the iron frame, the movable end is provided with a sliding device and can move in the area limited by the limit plate; the cutter 12 is placed on one side of the core barrel and Connected with the power unit, the movable end of t...

The invention relates to a shale sample smashing desorption device. The shale sample smashing desorption device comprises an iron frame, a limiting plate, a core storage drum, a hand wheel, a toothed rail, a debris collection drum and a cutter. The limiting plate is mounted on a face plate which is fixedly mounted on the iron frame, the core storage drum is mounted on the face plate of the iron frame, the cutter is arranged on one inner side of the core storage drum and connected with a power device, the hand wheel and the toothed rail are arranged outside the other side of the core storage drum, the hand wheel is in meshed connection with the toothed rail through a gear, one end of the toothed rail is connected with the connection plate, the tail end of the connection plate is placed in the core storage drum, and the core storage drum is provided with an air outlet. The shale sample smashing desorption device has the advantages that rock cores can be directly smashed for measurement of residual gas content, and low time consumption, high airtightness and high accuracy are achieved; by the aid of the hand wheel and the toothed rail for realization of rock core feeding, time and labor are saved; excellent airtightness is realized due to threaded connection between the debris collection drum and the core storage drum; the core storage drum in a split structure is convenient for filling of rock cores; by the aid of a seal ring arranged between a fixed end and a moving end of the core storage drum, high airtightness is achieved.
Description
technical field [0001] The invention relates to a desorber, in particular to a shale sample crushing desorber. Background technique [0002] China's shale gas and coalbed methane are widely distributed and rich in resources. Commercial mining has been carried out in some areas, but the level of development technology is relatively low. Reasonably guiding the development of shale gas and coalbed methane to replace traditional energy sources will be a major issue in the field of energy development worldwide in the future, and it will also fundamentally alleviate the problem of insufficient supply and demand of conventional natural gas in China. [0003] In the past, the determination of residual gas in coalbed methane and shale gas sampling and testing needs to wait for the natural desorption to end before crushing the core for measurement. loss. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention provides a shale samp...
