Technical Field

[0001] This utility model relates to the field of mineral crushing and sampling equipment, specifically to a multi-channel vacuum hydraulic crushing and sampling device. Background Technology

[0002] In geological geochronology and isotope tracing studies, stalagmites or mineral inclusions need to be broken up segment by segment to release fluids and collect gas samples. Most existing breaking devices are single-channel structures, requiring samples to be clamped, vacuumed, broken up, and vented sequentially. This necessitates re-vacuuming and steady-state background calibration after each breaking process, resulting in low testing efficiency; frequent opening and clamping introduces contamination risks; and identical pressure-displacement curves are difficult to replicate, affecting quantitative comparisons.

[0004] However, the above method can only crush minerals and cannot collect and detect gases. Furthermore, when detecting multiple gases at once, the gases cannot be mixed because different minerals contain different gases, and the gases collected from minerals in different regions may also have significant differences.

The side strip and the sealing strip seal the top of the sample cup and the support base, preventing gas leakage.

[0008] Preferably, the crushing mechanism includes an oil pump, the bottom wall of which is fixedly connected to the top wall of a support. The bottom wall of the oil pump is connected to several hydraulic cylinders via pipes mounted on the support.

Detailed Implementation

[0016] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings: Example: like Figures 1 to 8 As shown, this utility model provides a multi-channel vacuum hydraulic crushing and sampling device, including a support 1, a base 2 at the bottom of the support 1, and a sample carrying mechanism 3 at the top of the base 2 for holding samples. The sample carrying mechanism 3 can hold multiple samples simultaneously. A crushing mechanism 4 is located at the top of the sample carrying mechanism 3 corresponding to the sample position. The crushing mechanism 4 is located at the top of the support 1. A collection mechanism 5 for collecting the gas of each sample is provided between the base 2 and the sample carrying mechanism 3. Each collection mechanism 5 is connected to the bottom of its corresponding sample carrying mechanism 3. The base 2 is rotatably connected to the bottom of the support 1.

[0017] The sample carrying mechanism 3 includes a support base 31. The top of the support base 31 has several slots 311 evenly spaced around its perimeter. Sample cups 32 for holding samples are embedded within the slots 311. The side walls and bottom walls of the sample cups 32 are spaced apart from the side walls and bottom walls of the slots 311. Crushing mechanisms 4 correspond to the sample cups 32. An opening 321 is formed on the side wall of the sample cup 32 near its bottom. A first two-way valve 322 is installed within the opening 321. A connecting hole 34 is formed at the bottom of the slots 311, communicating with the gaps between the slots 311 and the side walls and bottom walls of the sample cups 32. The diameter of the connecting hole 34 is smaller than the diameter of the slots 311. The connecting hole 34 communicates with the collecting mechanism 5. A side strip 33 is fixedly connected to the top edge of the sample cup 32. A groove 312 is formed on the top wall of the support base 31. A sealing strip 313 is embedded in the bottom wall of the groove 312. The side strip 33 and the sealing strip 313 are movably pressed together.

[0018] The support base 31 is a cylinder with slots 311 cut around its top wall. A sample cup 32 is placed within the slots 311, so the diameter of the slots 311 is larger than the diameter of the sample cup 32, leaving gaps between their side walls and bottom walls. An opening 321 is formed in the side wall of the sample cup 32, and a first bidirectional valve 322 is installed within the opening 321. A connecting hole 34 is formed in the slots 311, connecting to the collection mechanism 5. When crushing occurs, the first bidirectional valve 322 opens, allowing the gas generated by the crushed minerals to flow from the first bidirectional valve 322 to the gap between the sample cup 32 and the slots 311, and then through the connecting hole 34 into the collection mechanism 5. After collection, the collected gas is analyzed using a mass spectrometer or other detection equipment. Since multiple sets of slots 311 and sample cups 32 are provided, multiple sets of collection mechanisms 5 are also provided. Therefore, the base 2 is rotatably connected to the bottom of the support 1, allowing different collection mechanisms 5 to be connected to the detection equipment through the rotation of the base 2 without moving the detection equipment. During crushing, under the pressure of the crushing mechanism 4, the side strip 33 presses the sealing strip 313 tightly. The sealing strip 313 is made of rubber and is ring-shaped to prevent gas from leaking from the gap between the sample cup 32 and the slot 311.

[0019] As another embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, the crushing mechanism 4 of this application includes an oil pump 41. The bottom wall of the oil pump 41 is fixedly connected to the top wall of the support 1. The bottom wall of the oil pump 41 is connected to several hydraulic cylinders 42 through pipelines provided on the support 1. A control valve group 44 is provided in the hydraulic cylinder 42 on the side of the piston 43 near the top wall of the support 1 to control the oil volume and hydraulic oil flow direction. A breaker hammer 45 is fixedly connected to the side of the piston 43 away from the top wall of the support, and the breaker hammer 45 corresponds to a sample cup 32. A sealing ring 451 is provided on the side wall of the breaker hammer 45, and the sealing ring 451 is movably fitted with the inner wall of the sample cup 32.

[0020] Powered by hydraulic pressure, piston 43 pushes piston rod 44 and breaker hammer 45 to apply pressure into sample cup 32. Multiple sets of hydraulic cylinders 42, pistons 43, piston rods 44, and breaker hammers 45 are provided, each corresponding to a position within sample cup 32. Control valve assembly 44 consists of a flow valve, a directional control valve, and a pressure control valve connected in series to regulate the flow rate, direction, and applied pressure of the hydraulic oil. The sealing ring 451 is made of rubber. During sample crushing, the breaker hammer 45 extends into sample cup 32, and the sealing ring 451 fits against the side wall of sample cup 32, achieving a dynamic seal. Control valve assembly 44 is controlled by a controller, which can individually control each piston rod 44 for crushing operations; therefore, only a few samples can be crushed in a single operation.

[0021] As another embodiment, such as Figure 1 , Figure 7 and Figure 8As shown, the collection mechanism 5 of this application includes a storage component 51 and a vacuum component 52. The storage component 51 is connected to the communication hole 34, and the vacuum component 52 is connected to the storage component 51. A frame 53 is fixedly connected between the support base 31 and the base 2 for fixing the storage component 51 and the vacuum component 52.

[0022] Storage assembly 51 includes a storage tank 511 located around the periphery of frame 53. An air inlet pipe 512 is detachably connected to the top of storage tank 511 and communicates with a connecting hole 34. An exhaust pipe 514 is detachably connected to the bottom of storage tank 511. The air inlet pipe 512 is equipped with a one-way valve 513, and the exhaust pipe 514 is equipped with a second two-way valve 515. The other end of the exhaust pipe 514 is connected to a detection device. The one-way valve 513 prevents gas from flowing from storage tank 511 to the connecting hole 34. Vacuum assembly 52 includes a vacuum pump 521 connected to storage tank 511 via a connecting pipe 522 equipped with a vacuum valve 523. The center of frame 53 and the center of support base 31 are open, and the vacuum pump 521 is located within the opening.

[0023] Multiple storage tanks 511 are provided, each corresponding to a sample cup 32 at a corresponding position, and connected to a connecting hole 34 via an air inlet pipe 512. The first two-way valve 322 and the second two-way valve 515 are both butterfly valves or ball valves, capable of bidirectional connection when opened. The top of the frame 53 is fixedly connected to the support base 31, and the bottom of the frame 53 is fixedly connected to the base 2. Both the frame 53 and the support base 31 have openings at their centers, and the vacuum pump 521 is fixed inside these openings. Because the storage tanks 511 are independently set, different types of samples can be crushed and the gas collected in the same test, or multiple identical samples can be crushed and collected in the same test.

[0024] Before crushing, the controller opens the vacuum valve 523, closes the first two-way valve 322 and the second two-way valve 515, and the vacuum pump 521 starts to evacuate the storage tank 511. The negative pressure generated during the evacuation process pulls the sample cup 32 downward, so that the edge strip 33 of the sample cup 32 is pressed tightly with the sealing strip 313 to achieve a seal, thereby improving the evacuation effect. After the evacuation is completed, the vacuum valve 523 is closed. During crushing, the controller controls the hydraulic system to lower the breaker hammer 45 at the corresponding sample position. When the sample is crushed, the first two-way valve 322 opens and the second two-way valve 515 closes. Since the storage tank 511 is under negative pressure, it is easier for gas to enter the storage tank 511. The second two-way valve 515 and the vacuum valve 523 are both closed, and the one-way valve 513 can only flow into the storage tank 511. Therefore, the storage tank 511 is in a sealed state after the gas is collected. After collecting the gas, rotate the base 2 so that the exhaust pipe 514 is aligned with the gas inlet of the testing instrument and connected through the nozzle. Rotate the base 2 so that different storage tanks 511 are aligned with the gas inlet of the testing instrument. When receiving gas, open the second two-way valve 515. After the gas in the storage tank 511 is vented, the first two-way valve 322 and the second two-way valve 515 are closed, the vacuum valve 523 is opened, and a vacuum is drawn. This process is repeated with the steps described above to perform the next crushing and collection.

[0025] In addition, in order to reduce the probability of dust generated by crushing clogging the first two-way valve 322 and other valves, a capillary mesh can be attached to the inner wall of the first two-way valve 322 for filtration.

[0026] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
