Description

Technical Field

[0001] The present application belongs to the technical field of hydrocarbon generation simulation, and in particular relates to a semi-automatic sample loading and unloading and cleaning device based on a hydrocarbon generation simulation instrument. Background Art

[0002] Hydrocarbon generation simulation mainly relies on the diagenetic and hydrocarbon-generating temperature and pressure simulation experimental unit for simulation, which can realize the dynamic control of temperature and pressure, and combine the geological conditions of geological samples (including tectonic evolution history, thermal evolution history and burial history, etc.) to simulate the hydrocarbon generation process of deposited organic matter in the actual geological hydrocarbon generation and expulsion formation environment as much as possible. The hydrocarbon generation potential and process of source rocks can provide a scientific basis for the effective development of oil and gas resources.

[0003] At present, the experimental sample loading requires the assembly of the upper and lower parts separately. After loading, the kettle is placed in the heating device as a whole, and then the basic parameters are input into the computer. Then the oil pump remote control is used to control the kettle to align with the groove of the overlying static rock pump. The static rock pressure and the main control pressure are controlled by the oil pump remote control to make the pressure value reach the preset pressure. When the experiment is completed, the furnace is opened to cool the kettle. When the kettle temperature can be touched by hand, the sample can be unloaded. After taking out the sample, it is rinsed with dichloromethane injection, and then continued to be rinsed with detergent and water, and finally rinsed with ultrapure water. Only the lower end cap and the lower end cover of the entire kettle body do not need to be cleaned, and the rest of the parts need to be cleaned with a syringe.

[0004] However, the above-mentioned sample loading and unloading and subsequent cleaning methods are prone to the following problems:

[0005] 1. When installing the sample at the bottom of the kettle, it is necessary to lift the kettle and align it, which is difficult and easy to misalign, and takes a long time;

[0006] 2. When the kettle is installed and laid out, the kettle must be moved as a whole to the heating device, and then the position of the kettle must be adjusted so that the water supply valve and the hydrocarbon exhaust valve on the right side of the kettle are aligned and tightened. The position adjustment is difficult, and the heating device has a small space, making it difficult to lay out;

[0007] 3. When unloading the sample in the experiment, the kettle body must be disassembled as a whole and placed separately in a high-temperature and high-pressure water-rock action simulator to press out the sample, which is a cumbersome process;

[0008] 4. After unloading, the kettle is heavy and difficult to clean. Summary of the invention

[0064] A specific embodiment of the present invention, as Figures 1 to 7 As shown, a semi-automatic sample loading and unloading and cleaning device based on a hydrocarbon generation simulation instrument is disclosed, comprising:

[0065] A furnace body 10 and a kettle body 11, wherein the kettle body 11 is fixed inside the furnace body 10 in a vertical direction;

[0066] A sample chamber, built into the kettle body 11;

[0067] A pressure rod 13 is disposed in the kettle body 11 and is located above the sample chamber, and a portion of the pressure rod 13 is located outside the kettle body 11;

[0068] The static rock pressure rod 14 is supported on the upper end of the pressure rod 13;

[0069] The lower end assembly 12 is placed in the kettle body 11 and is located below the pressure rod 13;

[0070] The lower end moving component 20 is connected to the lower end component 12, and the lower end moving component 20 can drive the lower end component 12 to move out of the kettle body 11 and enter the kettle body 11 and hold the sample chamber;

[0071] A cleaning mechanism 30 is arranged below the sample chamber;

[0072] The guiding mechanism 40 is used to draw the pressure rod 13 and the sample chamber which are pressed down by the static rock pressure rod 14 and moved out of the kettle body 11 into the cleaning mechanism 30 for cleaning.

[0073] In this embodiment, by fixing the kettle body 11 in the furnace body 10 in the vertical direction and using the lower end moving assembly 20, the sample chamber and its components can be automatically lifted and moved out of the kettle body 11 without moving the kettle body 11. The difficulty of moving the components in the kettle body 11 is reduced. At the same time, the setting of the cleaning mechanism 30 can automatically clean the sample chamber and the pressure rod 13 components in the kettle body 11, and the setting of the guide mechanism 40 is used to pull the pressure rod 13 and the sample chamber that are pressed down by the static rock pressure rod 14 and moved out of the kettle body 11 into the cleaning mechanism 30 for cleaning. With the arrangement of the above structure, when loading samples, when installing at the lower part of the kettle body 11, after the kettle body 11 is fixed, there is no need to lift the kettle body 11 and align it for loading; when the kettle body 11 is installed for laying out samples, there is no need to move the kettle body 11 as a whole to the heating device, and then adjust the position of the kettle body 11 so that the connection positions of the water replenishment valve and the hydrocarbon exhaust valve on the right side of the kettle body 11 are aligned and tightened, thereby reducing the difficulty of position adjustment and simplifying the laying out operation; when unloading samples in the experiment, there is no need to disassemble the kettle body 11 as a whole, and place it separately in the high-temperature and high-pressure water-rock action simulator to press out the sample, thereby reducing the process operation steps; after the unloading is completed, it is convenient to clean the kettle body 11.

[0074] In this embodiment, the hydrocarbon generation simulation instrument has the same experimental principle and structure as the present application, and the third difference is that the lower end assembly 12 of the present application is connected to the lower end moving assembly 20, and the kettle body 11 is fixed in the furnace body 10, so that the equipment of the present application does not need to be manually aligned and carried during sample placement. At the same time, the static rock pressure rod 14 of the present application is longer than the general static rock pressure rod 14, so that after the experiment is over, the static rock pressure rod 14 continues to move downward and can continue to push the sample bin downward. It should be noted that the external limit structure connected at both ends of the kettle body 11 needs to be changed accordingly to prevent the static rock pressure rod 14 from being unable to push out internal parts.

[0075] Figure 5 The structure of the existing hydrocarbon generation simulation instrument is briefly shown, including static rock pressure 1, main control pressure 2, hydrocarbon exhaust valve 3, vent valve 4, solvent valve 5, solvent replenishment valve 6, solvent tank 7, water replenishment valve 8, solvent air pressure valve 9, solvent evacuation valve 100, gas source 101 and vacuum pump 102. The above-mentioned various forces and structures of each component and their connection relationship belong to the existing technology and will not be repeated here. Figure 6 Some improved structures of the present application are briefly shown.

[0076] In some embodiments, the lower end moving component 20 includes a lower end transverse moving component and a lower end vertical moving component, the lower end transverse moving component includes a transverse drive motor seat 201 and a transverse guide rail 202, the lower end vertical moving component includes a vertical drive cylinder 203 and a connecting platform 204, the transverse guide rail 202 is connected to the connecting platform 204, the transverse drive motor seat 201 is driven and connected to the transverse guide rail 202, the connecting platform 204 is connected to the driving end of the vertical drive cylinder 203, the bottom of the furnace body 10 is an open structure, and the lower end component 12 is connected to the transverse drive motor seat 201.

[0077] By driving the motor seat 201 to move on the horizontal guide rail 202, the lower end component 12 can be driven to move closer to and away from the kettle body 11, and through the setting of the vertical driving cylinder 203 and the connecting platform 204, the vertical driving cylinder 203 can drive the lower end component 12 to enter and leave the kettle body 11.

[0078] The lower end assembly 12 includes a lower end rod, a lower pressure cap, a lower pressure cover, a sealing ring and other components.

[0079] In some embodiments, the cleaning mechanism 30 includes: a cleaning chamber 301, the upper end of the cleaning chamber 301 is open; a guide rail assembly 302, which is arranged on both sides of the cleaning chamber 301 and extends far away from one end of the cleaning chamber 301; a sliding cover 303, which is slidably connected to the guide rail assembly 302; a cleaning pneumatic mechanism 304, which is connected to the sliding cover 303 and is used to drive the sliding cover 303 to leave and cover the cleaning chamber 301, and the sliding cover 303 is provided with an opening;

[0080] The solvent pumping and discharging device is arranged at one end of the cleaning chamber 301, and is used to pump the cleaning solvent into the cleaning chamber 301, and discharge the cleaning solvent from the cleaning chamber 301 after the cleaning is completed.

[0081] In this embodiment, the sample chamber and other components are guided into the cleaning chamber 301 by the guide mechanism 40 to achieve the cleaning of the parts. When the sample chamber is placed in the cleaning chamber 301, the cleaning pneumatic mechanism 304 drives the slide cover 303 to slide on the guide rail assembly 302 to cover the cleaning chamber 301 to prevent the solution from splashing during cleaning. The solution pumping and discharging device includes a liquid pipeline, a pump and a valve. The cleaning solution is pumped into the cleaning chamber 301 by the pump and the solution is discharged through the valve. In this way, the immersion cleaning of the parts is achieved, and then the cleaning liquid such as water can be pumped in.

[0082] The cleaning pneumatic mechanism 304 includes a cleaning cylinder 305 and an L-shaped connecting frame 306 . The cleaning cylinder 305 is connected to the L-shaped connecting frame 306 , and the L-shaped connecting frame 306 is connected to the outer wall of the distal end of the sliding cover 303 .

[0083] It also includes a blowing mechanism, which is arranged at one end of the cleaning chamber 301 and is used to blow air into the cleaning chamber 301 after cleaning. The blowing mechanism may include a blower, and blowing air can make the parts dry quickly.

[0084] In some embodiments, the pressure rod 13 has a side outlet and inner holes running through both ends thereof, a detachable sealing assembly is provided in the inner hole at the upper end of the pressure rod 13, and the side outlet is connected to the inner hole; the guiding mechanism 40 includes:

[0085] The guide member 401 includes a guide wire, a strip-shaped airbag 403, and a front guide rod 402. The strip-shaped airbag 403 is sheathed on the guide wire. The strip-shaped airbag 403 and the guide wire have one end connected to the end of the front guide rod 402. The strip-shaped airbag 403 is attached with dense thin metal wires.

[0086] A clamping mechanism 41 is disposed above the pressure rod 13 and is used to clamp and move the front guide rod 402 up and down;

[0087] The blocking mechanism 42 is disposed at the bottom of the kettle body 11 and is used to move to the bottom of the kettle body 11 for blocking after the lower end assembly 12 moves out of the kettle body 11;

[0088] The delivery mechanism 43 is arranged on the blocking mechanism 42 and is drivingly connected to the front guide rod 402 to drive the front guide rod 402 to move back and forth;

[0089] A winding mechanism 44 is connected to the guide wire and is used to retract and release the guide wire;

[0090] The airbag inflation and deflation mechanism 45 is used to inflate and deflate the strip-shaped airbag 403 .

[0091] In this embodiment, the static rock pressure rod 14 is configured not to push the sample bin downward to move, and the sample bin can slide out of the kettle body 11 by its own weight after the lower end assembly 12 is removed by the lower end moving assembly 20. At this time, when the lower end moving assembly 20 moves out from under the kettle body 11, the blocking mechanism 42 is controlled to extend to the bottom of the kettle body 11 in time to block the parts under the kettle body 11 to prevent them from falling. Then, the delivery mechanism 43 drives the front guide rod 402 of the guide wire to insert into the sample bin and the pressure rod 13, and continue to extend upward, pass through the pressure rod 13, until the clamping mechanism 41 is in position, and the clamping mechanism 41 is controlled to clamp the front guide rod 402, and then the blocking mechanism 42 is removed, and the sample bin and the pressure rod 13 and other components slide downward along the front guide rod 402 and the strip airbag 403 by gravity. Since the guide member 401 is set in an arc shape, the sample bin can be slowly moved into the cleaning bin 301. During this process, the airbag inflation and deflation mechanism 45 does not inflate the strip airbag 403, and the winding mechanism 44 winds the strip airbag 403, so that the guide member 401 is in an arc shape. The guide wire can be a metal wire that can support the sample bin to prevent the strip airbag 403 from breaking.

[0092] It should be noted that the filter at the bottom of the sample chamber can be processed in advance, such as being removed or punched, and a valve that can be opened and closed can be provided to allow the guide member 401 to pass through when necessary, and the sealing component in the pressure rod 13 can be removed in advance. For example, the blocking component is used to block the bottom of the kettle body 11. When the filter moves to the bottom of the kettle body 11, the blocking mechanism 42 blocks the kettle body 11 in time, and after the filter is pulled out, the delivery mechanism 43 is continued to be controlled to deliver the guide member 401 to pass through the pressure rod 13.

[0093] When the sample bin is moved to the cleaning bin 301, the winding mechanism 44 unwinds the strip airbag 403, so that the guide 401 is in a relaxed state, and the airbag inflation and deflation mechanism 45 inflates the strip airbag 403, so that the strip airbag 403 is inflated, and the strip airbag 403 expands the inner wall of the sample bin and the pressure rod 13 and the metal wire arranged outside the strip airbag 403. The clamping mechanism 41 is controlled to move upward, and the winding mechanism 44 is controlled to wind at the same time, and the two cooperate to pull the strip airbag 403, so that the strip airbag 403 moves back and forth, and the holes in the sample bin and the pressure rod 13 can be frictionally cleaned.

[0094] For the case of different hole diameters, on the one hand, a uniform hole size can be set, and on the other hand, airbag segments with different expansion diameters can be set at the hole positions corresponding to the strip-shaped airbag 403 to accommodate airbags of different sizes.

[0095] After cleaning, the strip airbag 403 is further expanded, so that when the clamping mechanism 41 continues to move upward, the strip airbag 403 can tighten the sample compartment and other components, drive the sample compartment to move upward, and manually adjust the position of entering the kettle body 11 to assist the user in injecting samples. The strip airbag 403 can also be deflated to inject samples manually.

[0096] The blocking mechanism 42 includes a blocking drive motor 421 and a blocking member 422 , and the blocking member 422 can move to the bottom of the kettle body 11 . The blocking drive motor 421 can drive the blocking member 422 to move to the bottom of the kettle body 11 .

[0097] The delivery mechanism 43 includes a delivery motor 431 and a delivery gear. The blocking member 422 includes a blocking box 423. The delivery motor 431 is connected to the blocking box 423. The delivery motor 431 is connected to the delivery gear. The front guide rod 402 is penetrated into the blocking box 423 through a penetration hole. The front guide rod 402 is provided with vertically arranged teeth. The front guide rod 402 is meshed with the delivery gear. A removal groove 424 is also provided on the blocking box 423. The removal groove 424 is connected to the penetration hole. The diameter of the front guide rod 402 is smaller than that of the removal groove 424. The diameter of the strip air bag 403 is smaller than that of the removal groove 424. The opening direction of the removal groove 424 is toward the kettle body 11.

[0098] The delivery motor 431 drives the delivery gear to rotate, thereby driving the front guide rod 402 to move. After the front guide rod 402 is clamped by the clamping mechanism 41, the strip-shaped airbag 403 can be partially moved out of the blocking box 423 through the removal groove 424.

[0099] The surface of the front guide rod 402 can also be set as a rubber part, so that the front guide rod 402 can be driven to move without engagement, and its movement can be achieved only through squeezing and friction, so that the connection range of the reciprocating movement can be expanded.

[0100] The clamping mechanism 41 includes two clamping cylinders 411 arranged opposite to each other and a vertical moving motor. The vertical moving motor is connected to the clamping cylinders 411. After the clamping cylinders 411 move oppositely to clamp the leading rod 402, the vertical moving motor can move the leading rod 402 up and down.

[0101] The clamping cylinder 411 can clamp the front guide rod 402 by relative movement, and the vertical movement motor can move the clamping cylinder 411 up and down.

[0102] The present application also includes a bracket connected to the kettle body 11 and used to fix the kettle body 11 in the heating furnace. The bottom of the heating furnace is open to facilitate sample placement and loading.
