Shale bed crushing device for measuring gas content

Abstract

The invention discloses a shale bed crushing device for measuring the gas content. The shale bed crushing device comprises a sealed crushing box body. A driving motor is arranged on the upper end faceof a base foundation plate. An output shaft of the driving motor is provided with an incomplete bevel gear, wherein the incomplete bevel gear is alternately engaged with a double-faced bevel gear anda rotating bevel gear. A transmission transverse shaft is connected with one end of a transverse screw rod through a transmission mechanism. A circular-truncated-cone-shaped annular side plate is arranged at the side edge of the lower end face of a filter stop mesh plate. A rotating grinding mesh plate is arranged at the inner side of the circular-truncated-cone-shaped annular side plate. A rotating vertical shaft is arranged on the lower end face of the rotating grinding mesh plate, wherein the rotating vertical shaft vertically penetrates the bottom wall of the sealed crushing box body. Thelower end of the rotating vertical shaft is provided with a transmission bevel gear, wherein the transmission bevel gear is engaged with the double-faced bevel gear. The lower end face of the filterstop mesh plate is provided with grinding protrusions. The shale bed crushing device is simple in structure; shale can be crushed and ground multiple times, and it is guaranteed that the shale is completely crushed; furthermore, it is guaranteed that shale gas is completely emitted; and the shale bed crushing device is easy and convenient to operate, convenient and fast to use and high in practicability.

Description

technical field [0001] The invention relates to the technical field of shale gas equipment, in particular to a shale layer crushing device for measuring gas content. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale and its interlayers, mainly in the form of adsorption and free, and is mainly composed of methane. It is a clean and efficient energy resource and chemical raw material , mainly used for residential gas, urban heating, power generation, automobile fuel and chemical production, etc., with a wide range of uses. In the production process of shale gas, drainage is generally not required, and the production cycle is long, generally 30 to 50 years. The success rate of exploration and development is high, and it has high industrial economic value. In the process of shale gas exploration and development, it is also necessary to test the gas content of gas-bearing shale samples accordingly. During the test, it...

Problems solved by technology

But at the same time, the existing problem is that for the existing measuring devices, the natural desorption time of the shale samples is often longer during the use process, which leads to the greatly prolonging of the measuring test period, which greatly limits the The efficiency of the determination test also affects the performance of the determination device accordingly
