Description

Technical Field

[0001] The utility model relates to a material detection technology, in particular to a ceramsite proppant strength detection device. Background Art

[0002] Expanded clay is a porous and lightweight material. Most of the expanded clay is round or oval in shape, but some imitation gravel is not round or oval, but irregular gravel. The shape of expanded clay varies due to different processes. Its surface is a hard outer shell, which is ceramic or glazed, and has the function of water-proofing and air-retaining, and gives the expanded clay a higher strength. Because there are many raw materials and processes for producing expanded clay, there are many varieties of expanded clay, and thus many colors. It is used in various industries due to its different characteristics and advantages.

[0003] Ceramic granule proppants are widely used in oil and gas production due to their low density, high strength and good permeability. Due to the high strength requirements of ceramic granule proppants, the strength of ceramic granule proppants needs to be tested to ensure the strength quality of ceramic granule proppants. Since ceramic granules are round spheres, their strength is mainly concentrated in the surface shell strength. Conventional pressure testing methods are not sufficient to detect the true strength of ceramic granules and cannot objectively reflect the average strength level of ceramic granule proppants.

[0004] The existing "Light Aggregate and Its Test Methods" specification provides guidance on cylinder compression strength requirements and test methods for experimental equipment. The scale lines engraved on the outer surface of the stamping die are not convenient for observing the compression amount during the test, and there are safety hazards during observation.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0022] like Figures 1 to 4 In the embodiment of the ceramsite proppant strength detection device of the utility model shown, the ceramsite proppant strength detection device includes a detection platform 1, a bracket 2 is provided on the detection platform 1, a support plate 3 is fixedly connected to the top of the bracket 2, a guide rod 4 is fixedly connected between the support plate 3 and the detection platform 1, a stamping die frame 5 is slidably connected to the guide rod 4, a stamping die 6 is fixedly connected to the stamping die frame 5, a pressure cylinder 7 is provided on the detection platform 1 under the stamping die 6, and a scale line 8 is provided on the guide rod 4.

[0023] Specifically, the ceramsite proppant to be tested is placed in the pressure cylinder 7 and vibrated and flattened according to the specifications, and the vibrated and flattened pressure cylinder 7 is placed directly below the stamping die 6, so that the stamping die frame 5 drives the stamping die 6 to move downward to the upper surface of the pressure cylinder 7, and the scale at the bottom of the stamping die frame 5 is recorded, and the stamping die frame 5 continues to move downward to extrude the ceramsite proppant. When the stamping die 6 runs 20 mm in the pressure cylinder 7, the extrusion is stopped and the pressure value is recorded, and the cylinder pressure strength of the ceramsite proppant is converted.

[0024] In one embodiment of the present application, preferably, the distance from the starting position of the scale line 8 to the bottom surface of the stamping die frame 5 is consistent with the distance from the stamping die 6 to the top surface of the pressure cylinder 7. When the bottom surface of the stamping die 6 is flush with the top surface of the pressure cylinder 7, the bottom surface of the stamping die frame 5 is located at the starting position of the scale line 8, thereby ensuring the accuracy of the compression amount.

[0025] In one embodiment of the present application, preferably, a scale limit ring 9 is sleeved on the guide rod 4, and the scale limit ring 9 is slidably connected to the guide rod 4. A flower screw piece 10 is provided at the bottom of the scale limit ring 9, and a clamping nut 11 is threadedly connected to the flower screw piece 10, which is used to set the compression amount of the stamping die 6 in the pressure cylinder 7. The distance from the scale corresponding to the top surface of the scale limit ring 9 to the starting position of the scale line 8 is the compression amount of the stamping die 6 in the pressure cylinder 7. After the setting is completed, the clamping nut 11 is tightened, and the flower screw piece 10 squeezes the guide rod 4 so that the scale limit ring 9 is fixed and not easy to slip. When the stamping die frame 5 runs to the scale limit ring 9, the pressure data is recorded to avoid data distortion caused by the inability to control the compression amount, and different compression amounts can be adjusted and set according to different needs, thereby improving the applicability of the detection device.

[0026] In one embodiment of the present application, preferably, a groove is provided on the test bench 1, a pressure cylinder bottom 12 is provided in the groove, and the pressure cylinder 7 is placed on the pressure cylinder bottom 12 to avoid the pressure cylinder 7 and the pressure cylinder bottom 12 from moving on the test bench during the test, thereby improving the accuracy of the test and ensuring the safety of the test.

[0027] In one embodiment of the present application, preferably, a sealing ring 13 is arranged around the pressure cylinder bottom 12, and a handle 14 is fixedly connected to the sealing ring 13 to prevent the test material in the pressure cylinder 7 from overflowing from the gap between the pressure cylinder bottom 12 and the pressure cylinder 7. The handle 14 facilitates the removal of the pressure cylinder 7 and the pressure cylinder bottom 12 from the groove of the testing platform 1.

[0028] In one embodiment of the present application, preferably, an L-shaped groove 15 is provided on the sealing ring 13, and a protrusion 16 is provided on the outer wall of the pressure-bearing cylinder 7. The protrusion 16 is slidably connected to the L-shaped groove 15, so that the pressure-bearing cylinder bottom 12 and the pressure-bearing cylinder 7 are not easily disassembled as a whole during the test, which causes a decrease in the test accuracy and spillage of experimental materials.

[0029] In one embodiment of the present application, preferably, a press machine 17 is fixedly connected to the support plate 3, and a pressure push rod of the press machine 17 is fixedly connected to the stamping die frame 5, for pushing and resetting the stamping die frame 5 to move up and down, and displaying the applied pressure value.

[0030] In one embodiment of the present application, preferably, the pressure cylinder 7 is made of a high-strength and high-rigidity material so that it does not deform or the deformation is negligible during the cylinder pressure test, thereby ensuring that the cylinder pressure test data has a reference value.

[0031] In summary, the ceramsite proppant strength detection device in the above embodiment of the utility model, specifically, makes the convex block 16 on the pressure-bearing cylinder 7 to the L-shaped groove 15 on the sealing ring 13 to assemble the pressure-bearing cylinder 7 and the pressure-bearing cylinder bottom 12 into one, and then fills the ceramsite proppant into the pressure-bearing cylinder 7 and vibrates and scrapes it flat according to the specification requirements, and puts it into the groove of the detection table 1, starts the press 17 to push the stamping die frame 5 and the stamping die 6 downward to move downward, and when the bottom surface of the stamping die 6 moves to the top surface of the pressure-bearing cylinder 7, observe whether the bottom surface of the stamping die frame 5 coincides with the scale starting line, and slide the top surface of the scale limit ring 9 to the 20mm scale position And tighten the clamping nut 11, so that the press 17 continues to push the stamping die frame 5 downward, so that the stamping die 6 compresses the ceramsite, and the ceramsites are squeezed against each other. When the bottom surface of the stamping die frame 5 moves to the top surface of the scale limit ring 9, the stamping die 6 is compressed by 20mm in the pressure cylinder 7. The pressure value at this time is read and recorded, and the cylinder pressure strength value of the ceramsite proppant is converted. After the test is completed, the press is reset, the pressure cylinder 7 is taken out, and it is disassembled and cleaned. The ceramsite proppant strength detection device described in the present application adopts the method of engraving the displacement scale line on the outer guide column, so that it is convenient to observe the stroke of the stamping die during the test process to avoid safety hazards during observation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
