Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a device for testing the strength of ceramsite proppant. Background Technology

[0002] Expanded ceramsite, a porous lightweight material, is mostly spherical or oval in shape. However, some imitation crushed stone expanded ceramsite is not spherical or oval but irregularly shaped like crushed stone. The shape of expanded ceramsite varies depending on the manufacturing process. Its surface is covered with a hard outer shell, which is ceramic or glazed and has the functions of water and gas retention, as well as giving the expanded ceramsite high strength. Expanded ceramsite proppant is widely used in oil and gas extraction due to its low density, high strength and good permeability. Because of the high strength requirements for expanded ceramsite proppant, it is necessary to test the strength of expanded ceramsite proppant to ensure its strength quality.

[0003] For example, a ceramic proppant strength testing device disclosed in Chinese patent literature (announcement number: CN222635952U) makes it easier to observe the stroke of the stamping die during the test by engraving displacement scale lines on the outer guide column, thus avoiding safety hazards during observation.

[0004] However, during testing, the scale limit ring needs to be moved to the designated scale position and then locked by tightening the nut, which is a rather cumbersome operation. In addition, after the ceramsite proppant is added into the pressure cylinder, it needs to be manually compacted, which requires a lot of manual labor and seriously reduces the testing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome operation and high manual labor required for testing ceramic proppant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for testing the strength of ceramsite proppant includes a testing platform. A compaction mechanism is disposed below the testing platform. The compaction mechanism includes guide rods. The upper ends of two guide rods are symmetrically distributed and fixedly connected to the lower end of the testing platform. A mounting plate is fixedly connected to the lower end of each guide rod. A movable disc is slidably sleeved on the outside of each guide rod. A symmetrically distributed return spring is fixedly connected to the upper end of the movable disc. One end of each return spring is fixedly connected to the lower end of the testing platform. A placement groove is formed at the upper end of the testing platform. A through groove is formed in the inner bottom wall of the placement groove. A pressure-bearing cylinder is disposed inside the placement groove. A strength testing mechanism is disposed above the testing platform.

[0008] Preferably, the upper end of the movable disc is fixedly connected to a striking rod arranged in a ring array, and the upper ends of the plurality of striking rods are in contact with the lower end of the pressure-bearing cylinder.

[0009] Preferably, the upper end of the movable disk is fixedly connected to inclined extrusion blocks arranged in a circular array, and the upper end of the mounting plate is fixedly mounted with a servo motor.

[0010] Preferably, the output shaft of the servo motor is fixedly mounted with a rotating shaft via a coupling, and one end of the rotating shaft extends through to the upper end of the movable disk and is fixedly connected to a pressing rod.

[0011] Preferably, the strength testing mechanism includes columns, the lower ends of multiple columns are arranged in a rectangular array and fixedly connected to the upper end of the testing platform, and the upper ends of multiple columns are all fixedly connected to a top plate.

[0012] Preferably, each of the plurality of columns is slidably sleeved with a lifting plate, the lower end of the lifting plate is fixedly connected to a detection pressure block, and the upper end of the top plate is fixedly installed with a hydraulic cylinder.

[0013] Preferably, one end of the hydraulic cylinder piston rod passes through the top plate and is fixedly connected to the upper end of the lifting plate, and an infrared distance sensor is fixedly installed on the upper end of the detection platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the servo motor, extrusion rod, and inclined extrusion block are linked in the compaction mechanism, along with a return spring and a striking rod, to automatically complete the compaction of ceramsite, replacing manual operation, reducing labor intensity, and improving compaction consistency and testing efficiency. The strength testing mechanism uses a hydraulic cylinder to drive the testing block, and an infrared distance sensor accurately monitors the pressing distance. The strength is calculated by combining the pressure value. The process is automated, solving the problem of cumbersome traditional scale adjustment, and achieving efficient and accurate testing. This not only reduces manual labor but also improves testing efficiency. Attached Figure Description

[0025] Example

[0026] like Figures 1-4As shown, this utility model provides a technical solution: a ceramic proppant strength testing device, including a testing platform 1, on which a compaction mechanism and a strength testing mechanism are respectively set to work together to achieve efficient and accurate strength testing of ceramic proppant, which is suitable for the stringent requirements of oil and gas extraction for proppant quality control.

[0027] In the vibration mechanism below the testing table 1, the upper end of the guide rod 2 is symmetrically fixed to the lower end of the testing table 1, and the lower end is connected to the mounting plate 21, providing a precise guide track for the sliding of the movable plate 22. The movable plate 22 is slidably sleeved on the outside of the guide rod 2 and can reciprocate along the guide rod 2.

[0028] The movable disc 22 is connected to the testing table 1 via a return spring 23. The return spring 23 stretches and stores energy when the movable disc 22 slides down. After the extrusion rod 211 disengages from the inclined extrusion block 28, it releases the elastic force to drive the movable disc 22 to move upward and reset. This structure ensures the stability and continuity of the reciprocating motion of the movable disc 22, providing a power basis for the high-frequency striking of the pressure cylinder 26 by the striking rod 27.

[0029] The upper end of the movable disc 22 is provided with a ring-shaped array of striking rods 27, the upper end of which contacts the lower end of the pressure cylinder 26. During the reciprocating motion of the movable disc 22, the bottom of the pressure cylinder 26 is struck at a high frequency. This high-frequency striking causes the ceramsite proppant in the pressure cylinder 26 to be subjected to continuous vibration, thereby achieving uniform compaction. This avoids problems such as uneven force and inconsistent density that may occur with manual compaction, ensuring the uniformity of the ceramsite proppant distribution in the pressure cylinder 26 and providing a stable foundation for subsequent strength testing.

[0030] The inclined extrusion blocks 28 arranged in a ring array can convert the rotational motion of the extrusion rod 211 into the linear reciprocating motion of the movable disk 22 under the periodic extrusion of the extrusion rod 211, ensuring the automated operation of the compaction mechanism, replacing manual operation, and greatly improving compaction efficiency and consistency.

[0031] The servo motor 29 mounted on the mounting plate 21 drives the rotating shaft 210 to rotate through the output shaft. The rotating shaft 210 passes through the movable disk 22 and connects to the extrusion rod 211, providing rotational power for the extrusion rod 211.

[0032] The servo motor 29 can precisely control the speed and rotation angle, enabling the extrusion rod 211 to periodically extrude the inclined extrusion block 28, thereby stably driving the movable disc 22 to reciprocate along the guide rod 2, ensuring the stability and adjustability of the compaction mechanism, and further improving the compaction effect and testing efficiency of the ceramsite.

[0033] In the strength testing mechanism above the testing platform 1, the columns 3 are arranged in a rectangular array, with the lower end fixed to the testing platform 1 and the upper end connected to the top plate 31, providing stable guiding support for the sliding of the lifting plate 32.

[0034] The lifting plate 32 is slidably sleeved on the outside of the column 3 and can move vertically along the column 3. The hydraulic cylinder 34 installed on the top plate 31 has its piston rod passing through the top plate 31 and connected to the lifting plate 32. The hydraulic cylinder 34 serves as a power source and can precisely control the descent speed and pressure of the lifting plate 32, thereby driving the test block 33 to stably press the ceramic proppant, providing a stable and controllable pressure loading for strength testing.

[0035] The detection block 33 connected to the lower end of the lifting plate 32 acts directly on the surface of the ceramsite proppant. The hydraulic cylinder 34 applies pressure to perform strength testing. The infrared distance sensor 35 installed on the upper end of the testing platform 1 can accurately monitor the displacement changes of the detection block 33.

[0036] During the testing process, the infrared distance sensor 35 collects the pressing distance data of the testing block 33 in real time and transmits it to the external PLC controller. Combined with the pressure value of the testing block 33, the cylinder compressive strength value of the ceramsite proppant can be automatically calculated. This automated testing method solves the problems of cumbersome scale adjustment and large errors in manual reading in traditional testing devices, and realizes the high efficiency and accuracy of ceramsite proppant strength testing.

[0037] The working process of this utility model:

[0038] Step 1: Pour the ceramsite proppant into the pressure cylinder 26 in the placement slot 24 of the testing platform 1. Start the servo motor 29 of the compaction mechanism. The motor output shaft drives the rotating shaft 210 to rotate. The extrusion rod 211 on the rotating shaft 210 rotates synchronously. When the extrusion rod 211 rotates, it extrudes the inclined extrusion block 28 on the movable disk 22, causing the movable disk 22 to slide down along the guide rod 2. The return spring 23 stretches and stores energy. When the extrusion rod 211 disengages from the inclined extrusion block 28, the return spring 23 releases its elasticity, causing the movable disk 22 to move upward quickly. The striking rods 27 in the ring array at the upper end of the movable disk 22 move upward synchronously, frequently striking the bottom of the pressure cylinder 26. Through the continuous cycle of extrusion, reset, and striking, the ceramsite proppant in the pressure cylinder 26 is uniformly compacted, replacing manual compaction, ensuring consistent density, and improving the accuracy of testing.

[0039] Step two: After compaction, the hydraulic cylinder 34 of the strength testing mechanism is activated. The piston rod of the hydraulic cylinder 34 extends, pushing the lifting plate 32 below the top plate 31 down along the column 3. The detection block 33 at the lower end of the lifting plate 32 then approaches the pressure cylinder 26. When the detection block 33 adheres to the surface of the ceramsite proppant, the infrared distance sensor 35 is activated to monitor the distance between the detection block 33 and its initial position in real time, providing a data basis for strength conversion. The hydraulic cylinder 34 continues to push the detection block 33 down to press the ceramsite proppant, and the pressure of the detection block 33 gradually increases. The infrared distance sensor 35 is activated to monitor the distance between the detection block 33 and its initial position in real time, providing a data basis for strength conversion. Sensor 35 continuously collects data on the downward pressure distance and transmits it to an external PLC controller. The PLC controller is a mature technology and will not be described in detail here. When the detection block 33 is pressed down to a preset distance, such as the detection stroke specified in the industry standard, the PLC controller receives the sensor signal and controls the hydraulic cylinder 34 to stop pressing down. At the same time, it records the pressure value of the detection block 33. Based on the cylinder pressure strength detection principle, through a preset formula and the conversion relationship between pressure value and downward pressure distance, the PLC controller automatically calculates the cylinder pressure strength value of the ceramsite proppant and generates a test report.
