Shale sample smashing desorption device

Technical Field

The invention relates to a desorption device, in particular to a crushing a shale sample.

Background Art

China's the shale was mad widely distributed and coal-bed gas, rich in resources, some areas have carried out the commercial exploitation, but development of technology level is relatively low. Reasonable guide development the shale was mad and coal-bed gas will be to replace the traditional sources of future world energy development within the range of one of the major issues in the field, can be fundamentally ease the problem of insufficient natural gas supply and demand.

In the past, coalbed methane, shaley gas sampling test work residual gas in the determination of the natural desorption of the need for waiting for the end of the core to be taken by crushing determination, not only time-consuming, and the device air tightness cannot be guaranteed, easily lead to the loss of the desorbed gas.

Content of the invention

The present invention is directed to the problem in the prior art, provides a shale sample crushing desorption device, the desorption device can be directly crushing core determination of residual gas content, time consuming and short, the gas tightness is good, high accuracy.

In order to solve the problems of the existing technology, this invention adopts the following technical scheme is:

Shale sample crushing desorption device, comprises an iron rack, the limiting plate, chu Xin barrel, a hand wheel, rack, and cutter collection filings barrel ,

The iron frame is provided with a panel, the limit plate is installed in the panel, the barrel mounting chu Xin on the panel of the iron frame, chu Xin tool is placed in the barrel and one side of which is connected with a power device, the other side of the barrel chu Xin the outside of which is provided with a handwheel and a rack rail, the hand wheel through the gear is meshed and connected with the rack, one end of the rack is connected with the connecting board, is placed at the distal end of the connecting plate in the barrel for chu Xin , chu Xintong is provided with a gas outlet port.

The power device is a motor, the motor is connected through the belt and the cutter.

chu Xintong the split type, which comprises a fixed end and the free end, the fixed end and the movable end is connected by a bolt.

The movable end of the seal ring is arranged between the fixed end.

The chu Xintong is connected with the main barrel.

The invention has the advantages and effects:

Crushing a shale sample of the present invention, because of including iron frame, limit plate, chu Xin barrel, a hand wheel, rack, and cutter collection filings barrel , can be directly crushing core determination of residual gas content, time consuming and short, the gas tightness is good, high accuracy. Through the hand wheel and rack realize the core feeding, saving labor and time. Chipping chu Xin threaded connection with the barrel, the gas tightness is good. chu Xintong to split, convenient fill the core. chu Xintong fixed end and the movable end of a sealing ring is arranged between the, good air tightness.

Figure 3 is a schematic diagram of the state of the present invention is a sample of shale core is crushed.

Mode of execution

As shown in Figure 1, 2 is shown, a shale sample crushing of the present invention, comprises an iron rack 11, limit plate 1, chu Xintong 2, the hand wheel 4, rack 7, the main barrel 10 and the tool 12,

The iron frame 11 is provided with a panel fixed on, a limit plate 1 mounted on the panel, when the filled adds the core is used to restrict the direction of movement of the barrel chu Xin ; chu Xintong 2 is installed in the upper panel of the iron frame, chu Xintong the split type, which comprises a fixed end and the free end, the fixed end and the movable end, through the bolt 3 is connected. The fixed end is fixed on the panel of the iron frame, mounted on the movable end of the on the panel of the iron frame, are provided with a sliding movable end of the limiting device and can move in the area of the plates define; cutting tool 12 is placed in the barrel chu Xin and one side of which is connected with a power device, the active chu Xintong the outside of which is provided with a handwheel 4 and a rack rail 7, a hand wheel 4 and the rack 7 through the gear is meshed and connected with, one end of the rack is connected with the connecting board, is placed at the distal end of the connecting plate in the barrel for chu Xin , chu Xintong is provided with an air outlet 8. The lower end of the rack is connected with the plate is placed in the barrel chu Xin , when the hand wheel to drive a rack rail rotates to the right, pushing the connecting core and the cutter grinding.

The fixed end is provided with a sealing ring is arranged at the end part of the groove, the sealing ring groove is provided with a seal ring 9.

The power device is a motor 5, the motor is fixed to the lower part of the iron frame panel, motor 5 through the belt 6 with the cutting tool 12 is connected.

The pencil chu Xintong is arranged below the barrel 10, with the chipping chu Xintong barrel 10 is connected with the. chu Xintong threaded connection with the main barrel.

The working mode of the present invention are as follows:

As shown in Figure 2, 3, will be connected with the movable end of the fixed barrel chu Xin the two bolt is loosened, the barrel chu Xin along the direction of the arrow is pulled out on the left side of the limiting plate to the left, exposing the cutting tool; and then along to the direction of the arrow pull in the direction of the opening of the limit plate, and chu Xintong stagger the position of the cutting tool is not in a straight line, the outer side of the rack to the, at this time can be determined to be residual gas chu Xin barrel core is filled, to prevent the collision of the core and the cutter; the sliding the slide chu Xintong must be close to the limit plate, skew correction in time, preventing the push-and-pull in the location in a timely manner.

Fill the core to the sliding track reverse the earlier chu Xin barrel pushing the original position, tighten the bolts, and then put in a sealing ring groove of the sealing ring.

The filling core, the lower side of the barrel the main inspection equipment whether of screwing, to prevent the gas leakage, the power supply after examination, the hand wheel is rotated in the direction of the core the push, start processing, the speed can be determined according to operating conditions source, all treats the core collection end gas after breaking, chipping of the device below the pouring off waste core barrel, is after cleaning.
