Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mineral research, and in particular to a core cleaning device. Background Technology

[0002] In geological exploration and mineral resource assessment, rock cores, as core samples directly reflecting the geological characteristics, mineral composition, and structure of underground rock strata, are crucial. The surface cleanliness of these cores directly determines the accuracy of subsequent lithological analysis, physical property testing, and compositional analysis. After being extracted from underground drilling, rock cores are typically covered with a large amount of impurities such as mud, rock cuttings, and drilling fluid residue. If not thoroughly cleaned, these impurities will obscure the original structure of the core, leading to deviations in key tests such as microscopic observation and spectral analysis, and even misjudging geological conditions. Therefore, core cleaning is a critical step in geological exploration and mineral research. Currently, core cleaning operations in the industry still rely primarily on traditional manual methods. Operators use hand hoses to rinse the core surface and manually wipe it with brushes. This method is not only labor-intensive and inefficient but also fails to meet the sample processing needs of large-scale exploration projects.

[0003] As exploration extends to deeper and more complex strata, the variety of core sizes and complex structures places higher demands on the adaptability of cleaning tools, sample protection, and environmental friendliness. Utility Model Content

[0004] The purpose of this invention is to provide a core cleaning device that can solve the problems mentioned in the background art.

[0005] This utility model provides a core cleaning device, including a cylinder. The top end of the cylinder is provided with an upper elastic clamping assembly, and the bottom end is provided with a lower elastic clamping assembly. The outer walls of the upper elastic clamping assembly and the lower elastic clamping assembly are connected by a connecting rod. A cleaning assembly is provided between the upper elastic clamping assembly and the lower elastic clamping assembly. Both the upper elastic clamping assembly and the lower elastic clamping assembly are rotatably connected to the cleaning assembly. The cleaning assembly includes a brush disposed on the inner wall of the cylinder. The bottom of the cylinder is provided with a perforated layer, and a waste liquid collection assembly is disposed below the perforated layer.

[0006] Preferably, the upper elastic clamping assembly and the lower elastic clamping assembly have the same structure, both including a plurality of arc-shaped clamping arms symmetrically arranged inside the cylinder, the clamping arms being connected to the inner wall of the cylinder by a spring, and a limiting assembly being provided on the outer side of the spring.

[0007] Preferably, the limiting component includes a limiting cylinder fixedly connected to the inner wall of the cylinder, a sleeve sleeved on the outer side of the limiting cylinder, one end of the sleeve being fixedly connected to the outer side of the clamping arm, and the limiting cylinder and the sleeve being slidably connected.

[0008] Preferably, the sleeve has a plurality of limiting grooves along the axial direction on the inner wall of one end near the cylinder, and a limiting block is provided on the outer side of the sleeve end, the limiting block being able to slide along the limiting grooves.

[0009] Preferably, the inner side of each clamping arm is provided with an anti-slip silicone layer.

[0010] Preferably, the top of the cylinder is provided with an end cap, and the bottom of the end cap is provided with a spray assembly. The spray assembly includes a nozzle disposed at the center of the bottom of the end cap, and the nozzle inlet passes through the end cap and connects upward to a water tank.

[0011] Preferably, a drying component is provided on the inner wall of the lower cylinder below the lower elastic clamping assembly.

[0012] Preferably, the drying assembly includes a support ring coaxial with the cylinder, an interlayer is provided between the support ring and the cylinder, a plurality of air outlets are provided on the inner side of the support ring, the inlet end of the air outlet is connected to the inlet of the drying fan through an air outlet pipe, and the drying fan is disposed in the interlayer.

[0015] Beneficial effects: This invention uses a cylindrical body as the main body of the device, providing a stable installation foundation for each functional component. The upper and lower elastic clamping components can adapt to rock cores of different specifications through their elastic properties, achieving stable clamping of the rock cores and preventing shaking or displacement during cleaning. Simultaneously, the elastic structure reduces hard compression on the rock core surface, preventing core breakage or damage to surface texture. The upper and lower elastic clamping components are connected by a connecting rod, forming a stable whole and ensuring uniform cleaning. The cleaning components can rotate flexibly relative to the clamped rock core, and the brush can fully conform to the outer circumference of the rock core for friction cleaning, achieving all-round, no-dead-angle cleaning of the rock core surface, significantly improving the impurity removal effect and cleaning efficiency. The perforated layer at the bottom of the cylinder allows waste liquid and detached rock debris generated during the cleaning process to flow smoothly downwards. The waste liquid collection component below can collect this waste liquid and rock debris centrally, facilitating the unified treatment of rock debris and the recycling and reuse of cleaning liquid, improving the convenience and environmental friendliness of the device.

[0016] Through the synergistic effect of its various parts, the overall structure of this utility model ensures the quality and efficiency of core cleaning while also taking into account ease of operation and structural stability, effectively meeting the core requirements of core cleaning.

[0023] Example 1 like Figures 1-3 As shown, a core cleaning device includes a cylinder 1. The top of the cylinder 1 is provided with an upper elastic clamping component 4 and the bottom is provided with a lower elastic clamping component 5. The outer walls of the upper elastic clamping component 4 and the lower elastic clamping component 5 are connected by a connecting rod 6. The connecting rod 6 fixes the position between the two components, thereby improving the stability of the overall device.

[0024] The upper elastic clamping assembly 4 and the lower elastic clamping assembly 5 have the same structure, both including several arc-shaped clamping arms 501 symmetrically arranged inside the cylinder 1. Each clamping arm 501 has an anti-slip silicone layer 507 on its inner side to enhance friction with the rock core 10 and prevent damage to the surface of the rock core 10. The upper and lower ends of the clamping arms 501 have inclined surfaces to facilitate guiding the rock core 10 into the cavity between the clamping arms 501. The clamping arms 501 are connected to the inner wall of the cylinder 1 by springs 504, which are always in a compressed state. Limiting components are provided on the outer side of the springs 504. Under the action of the springs 504, the clamping arms 501 can adapt to clamping rock cores 10 of different diameters. The springs 504 are preferably made of high-strength spring steel 504, which has stable elastic properties and a long fatigue life, meeting the needs of frequent clamping operations. The limiting assembly includes a limiting cylinder 503 fixedly connected to the inner wall of the cylinder 1, and a sleeve 502 sleeved on the outer side of the limiting cylinder 503. One end of the sleeve 502 is fixedly connected to the outer side of the clamping arm 501, and the limiting cylinder 503 and the sleeve 502 are slidably connected. The inner wall of the sleeve 502 near the end of the cylinder 1 is provided with a plurality of limiting grooves 509 along the axial direction, and a limiting block 508 is provided on the outer side of the end of the sleeve 502. The limiting block 508 can slide along the limiting grooves 509, and the sliding trajectory of the limiting block 508 can be limited by the limiting grooves 509, thereby limiting the compression stroke of the spring 504.

[0025] A screw 505 is provided on the outer side of the clamping arm 501. The screw 505 is arranged radially along the cylinder 1 and is located inside the spring 504. One end of the screw 505 is fixedly connected to the clamping arm 501, and the other end passes through the side wall of the cylinder 1 and is threadedly connected to the nut 506. In the initial state, the screw 505 is pulled to move the limiting block 508 along the limiting groove 509 to the shortest distance between the clamping arm 501 and the inner wall of the cylinder 1. The position of the clamping arm 501 is fixed by the nut 506. After the rock core 10 is placed, the nut 506 is loosened, and the clamping arm 501 presses the rock core 10 under the action of the spring 504.

[0026] A cleaning component 7 is provided between the upper elastic clamping component 4 and the lower elastic clamping component 5. Both the upper elastic clamping component 4 and the lower elastic clamping component 5 are rotatably connected to the cleaning component 7 through the bearing 13 to enhance the smoothness of rotation. The upper elastic clamping component 4 and the cleaning component 7 are provided with water-blocking edges 12 on the lower part of the inner wall of the corresponding cylinder 1. The water-blocking edges 12 can block the gaps between the upper elastic clamping component 4 and the cleaning component 7, and between the cleaning component 7 and the lower elastic clamping component 5, to prevent water from entering the gaps and affecting the rotation of the cleaning component 7.

[0027] The cleaning assembly 7 includes a brush 701 mounted on the inner wall of the cylinder 1. The brush 701 is fixedly connected to the inner wall of the cylinder 1 via an annular support frame. The length of the brush 701 is greater than the maximum distance between the clamping arm 501 and the inner wall of the cylinder 1, ensuring that the core 10 can always be brushed. The operator can rotate the cylinder 1 corresponding to the cleaning assembly 7 to brush the core 10.

[0028] The cylinder 1 has an end cap 2 at its top, and a spray assembly at the bottom of the end cap 2. The spray assembly includes a nozzle 3 located at the center of the bottom of the end cap 2. The nozzle 3 is a high-pressure conical nozzle, and its spray range completely covers the top section of the rock core 10, ensuring thorough rinsing without any blind spots. The nozzle 3 inlet passes through the end cap 2 and connects upwards to a water tank via a pipe. The nozzle 3 and the water tank are detachably connected for easy transport. A water pump is installed on the pipe for easy adjustment of the spray pressure. The water tank and water pump are commonly used equipment in this field and are omitted in the figure.

[0029] A drying assembly 8 is provided on the inner wall of the lower elastic clamping assembly 5 below the cylinder 1. The drying assembly 8 includes a support ring 804 coaxial with the cylinder 1. A sealing interlayer is provided between the support ring 804 and the cylinder 1. Several air outlets 803 are provided on the inner side of the support ring 804. The inlet end of the air outlet 803 is connected to the inlet of the drying fan 801 through an air outlet pipe 802. The drying fan 801 is located in the interlayer. The end of the air outlet pipe 802 near the air outlet 803 is inclined downward to prevent spray water from entering the drying fan 801 along the air outlet pipe 802. The distance between the support ring 804 and the cylinder 1 is less than the minimum distance between the clamping arm 501 and the cylinder 1 to prevent damage to the support ring 804 when the core 10 falls, while ensuring a smooth ventilation path between the air outlets 803 and the core 10.

[0030] The bottom of the cylinder 1 is provided with a perforated layer 11, and a waste liquid collection component 9 is provided below the perforated layer 11. The perforated layer 11 facilitates the falling of impurities during the cleaning process of the rock core 10 into the waste liquid collection component 9 below.

[0031] The waste liquid collection assembly 9 includes a waste liquid tank 901. A removable filter screen 903 is located at the center of the top of the waste liquid tank 901, effectively intercepting rock debris in the cleaning fluid. The top of the waste liquid tank 901 is inserted into the bottom of the cylinder 1. An annular groove 904 is located on the top of the waste liquid tank 901, and the cylinder 1 can be inserted into the annular groove 904. A sealing strip is embedded at the insertion point to effectively prevent waste liquid leakage. A drain outlet 902 with a sealing cap is located at the bottom of the side wall of the waste liquid tank 901, which can be connected to a hose to guide the filtered cleaning fluid back to an external water tank, realizing the recycling of the cleaning fluid and significantly saving water resources.

[0032] Work process: In the initial state, pulling the screw 505 causes the limiting block 508 to move along the limiting groove 509 until the distance between the clamping arm 501 and the inner wall of the cylinder 1 is the shortest. The clamping arm 501 is then fixed in position by the nut 506. When placing the rock core 10, the end cover 2 is opened and the nut 506 is loosened. The clamping arm 501 presses the rock core 10 under the action of the spring 504. After pressing the rock core 10, the nut 506 is tightened again to fix the position of the clamping arm 501, increasing the supporting force of the clamping arm 501 on the rock core 10. Cover the end cap 2, connect the nozzle 3 to the water tank through the pipe, start the water pump, the nozzle 3 sprays out a cone-shaped water flow, the operator pushes the cleaning component 7 to rotate the outer wall of the cylinder 1, the brush 701 and the water flow work together to achieve all-round cleaning, the cleaning liquid flows into the waste liquid tank 901 through the hollow layer 11, and the rock debris is intercepted by the filter screen 903. After cleaning, turn off the water pump, start the drying fan 801, and blow hot air upward from the bottom air outlet 803 onto the core 10. After the surface of the core 10 is dry, turn off the drying fan 801 and take out the core 10.
