Description

Technical Field

[0001] This utility model relates to the field of rock cuttings processing technology, and in particular to a rock cuttings drying device for geological logging. Background Technology

[0002] In oil drilling operations, high-speed drilling mud inside the drill string carries downhole cuttings to the surface. For example, a cuttings washing device for oil geological logging, disclosed in patent number CN202420544442.1, facilitates the washing of cuttings during the oil geological logging cuttings washing process, saves manual washing steps, simplifies the washing process, reduces the workload of workers, and improves work efficiency. However, the washed cuttings need to be air-dried for storage and analysis. When the cuttings are air-dried, the accumulation of cuttings leads to low drying efficiency, with the surface dry while the bottom is damp. Manually spreading the cuttings would increase labor intensity, and conventional open-type processing is prone to introducing impurities, such as being covered by wind and sand or contaminated by on-site oil.

[0003] Based on this, the applicant is considering designing a geological logging cuttings drying device that can automatically flatten and efficiently air dry the cuttings. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a geological logging cuttings drying device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A geological logging cuttings drying device includes a drying barrel, a drive motor, and a leveling component. The drying barrel has at least one drying chamber arranged along its axial direction. Each drying chamber includes a perforated plate at its bottom and the leveling component, which rotates within it. The drive motor drives the leveling component to rotate. The drying barrel has a material inlet on its side wall that communicates with the interior of the drying chamber, and each drying chamber has at least one material inlet corresponding to it.

[0007] The working principle and advantages of the geological logging cuttings drying device in this technical solution are as follows:

[0008] Because the feed inlet is connected to the inside of the drying chamber, the cleaned rock chips can be directly poured into the drying chamber from the feed inlet on the side wall of the drying barrel. After the drive motor starts, it drives the leveling component to rotate within the drying chamber. The rotation of the leveling component flattens the rock chips that have been poured into the drying chamber, ensuring even distribution of the rock chips on the perforated plate. This avoids localized accumulation of rock chips and solves the problem of surface dryness while the bottom layer remains damp. After the rock chips are flattened, the perforated plate design facilitates air circulation within the drying chamber, accelerating the evaporation and dissipation of moisture from the rock chips, thus achieving efficient drying. This solution, through the cooperation of the drive motor and the leveling component, achieves efficient drying of the rock chips. The automatic leveling of rock fragments eliminates the need for manual operation, reducing labor intensity and lightening the burden on staff. The rotating leveling components and the perforated plate structure promote air circulation, improve drying efficiency, reduce the drying time required for rock fragments, and accelerate subsequent storage and analysis processes. The drying drum can be equipped with multiple drying chambers, each with a corresponding feed inlet, enabling simultaneous drying of rock fragments from different collection depths, further enhancing work efficiency. Compared to open processing, this device operates within a relatively enclosed drying drum, effectively preventing external debris from contaminating the rock fragments, ensuring their purity, and facilitating subsequent geological analysis.

[0009] Furthermore, the bottom of the drying barrel is provided with an installation cavity located below the drying chamber, and the drive motor is fixedly installed in the installation cavity.

[0010] Furthermore, the leveling component includes a connecting shaft and a leveling support rod connected to the outer wall of the connecting shaft. One end of the connecting shaft is provided with an insertion groove, and the other end is provided with an insertion protrusion adapted to the insertion groove. The end of the connecting shaft is inserted into the output shaft of the drive motor.

[0011] Furthermore, the outer wall of the connecting shaft is provided with a plurality of connecting screw holes axially, and the end of the flattening support rod is provided with a connecting stud that is threadedly connected to the connecting screw holes.

[0012] Furthermore, a central hole is provided at the center of the hollow plate for the connecting shaft to pass through.

[0013] Furthermore, the perforated plate is detachably connected to the inner wall of the drying barrel; the inner wall of the drying barrel is provided with a plurality of support blocks protruding out, each support block is provided with a positioning protrusion on its top side, and the perforated plate is provided with a plurality of positioning holes corresponding to the positioning protrusions.

[0014] Furthermore, the top of the drying barrel is detachably connected to a cover.

[0015] Furthermore, the outer wall of the drying barrel is provided with an air duct that communicates with its interior, and the air duct is used to supply air into the drying barrel.

[0016] Furthermore, it also includes a movable base, on which the drying barrel is hinged.

[0017] Furthermore, a drainage hole is provided at the bottom of the air-drying barrel. Attached Figure Description

[0030] Refer to together Figures 1 to 6 This embodiment provides a geological logging cuttings drying device, which includes a drying barrel 300, a drive motor 310, and a flattening component 320. The drying barrel 300 has at least one drying chamber 302 arranged along its axial direction. The drying chamber 302 includes a hollow plate 340 arranged at the bottom and a flattening component 320 arranged rotatably inside. The drive motor 310 is used to drive the flattening component 320 to rotate. The drying barrel 300 has a material inlet 380 communicating with the inside of the drying chamber 302 on its side wall, and each drying chamber 302 is provided with at least one material inlet 380.

[0031] In this embodiment, since the feed inlet 380 is connected to the interior of the drying chamber 302, the cleaned rock chips can be directly poured into the drying chamber 302 from the feed inlet 380 on the side wall of the drying barrel 300. After the drive motor 310 starts, it can drive the leveling component 320 to rotate within the drying chamber 302. The rotation of the leveling component 320 flattens the rock chips piled up in the drying chamber 302, ensuring even distribution of the rock chips on the perforated plate 340. This avoids localized accumulation of rock chips and solves the problem of surface dryness while the bottom layer remains damp. After the rock chips are leveled, the design of the perforated plate 340 facilitates air circulation within the drying chamber 302, accelerating the evaporation and dissipation of moisture from the rock chips, thereby achieving efficient drying. This solution utilizes the drive motor 310... The combination of the 0 and the leveling component 320 enables automatic leveling of rock cuttings, eliminating the need for manual operation, reducing labor intensity, and alleviating the burden on staff. The rotation of the leveling component 320 and the structural design of the perforated plate 340 promote air circulation, improve drying efficiency, reduce the drying time required for rock cuttings, and accelerate subsequent storage and analysis processes. The drying barrel 300 can be equipped with multiple drying chambers 302, each with a corresponding feed inlet 380, enabling simultaneous drying of rock cuttings from different collection depths, further improving work efficiency. Compared with open processing, this device operates within a relatively enclosed drying barrel 300, effectively preventing external debris from contaminating the rock cuttings, ensuring the purity of the rock cuttings, and facilitating subsequent geological analysis.

[0032] Preferably, such as Figures 1 to 5As shown, the bottom of the drying barrel 300 is provided with an installation cavity 301 located below the drying chamber 302, and the drive motor 310 is fixedly installed in the installation cavity 301. Placing the drive motor 310 in the installation cavity 301 at the bottom of the drying barrel 300 makes the structure of the entire device more compact, reduces the footprint of the device, and facilitates installation and use in limited spaces. The installation cavity 301 provides good protection for the drive motor 310, extends the service life of the motor, and ensures the stable operation of the device. The installation cavity 301 can isolate the noise generated by the drive motor 310 during operation to a certain extent, reduce the impact of noise on the surrounding environment, and provide a more comfortable working environment for operators. Moreover, when the drive motor 310 is inside the drying barrel 300, the heat emitted by the drive motor 310 during operation can also play a certain drying role, which is conducive to further improving the drying efficiency. No additional heating device is required, and the naturally emitted heat is relatively mild and will not affect the rock debris structure.

[0033] Preferably, such as Figures 3 to 6 As shown, the flattening component 320 includes a connecting shaft 321 and a flattening support rod 322 connected to the outer wall of the connecting shaft 321. One end of the connecting shaft 321 is provided with an insertion groove 3212, and the other end is provided with an insertion protrusion 3211 adapted to the insertion groove 3212. The end of the connecting shaft 321 is inserted into the output shaft of the drive motor 310. The flattening component 320 adopts a combination structure of connecting shaft 321 and flattening support rod 322. The connecting shaft 321 is connected to the output shaft of the drive motor 310. When the drive motor 310 starts, it drives the connecting shaft 321 to rotate, which in turn drives the flattening support rod 322 to rotate. The design of the insertion groove 3212 and insertion protrusion 3211 at both ends of the connecting shaft 321 makes the connection between the flattening component 320 and the output shaft of the drive motor 310 more convenient. When the leveling component 320 needs to be replaced or maintained, it can be quickly disassembled and installed, reducing downtime and improving work efficiency. Multiple leveling components 320 can be quickly plugged in, and the number of drying chambers 302 and the number and position of leveling support rods 322 can be flexibly adjusted. The modular design and quick disassembly and assembly function of the leveling component 320 make it easy to inspect, clean or replace the leveling component 320 during daily maintenance, reducing maintenance costs and difficulty. Specifically, the output shaft of the drive motor 310 is provided with a connecting groove, and the connecting shaft 321 is plugged into the output shaft of the drive motor 310 through a section provided with a plugging protrusion 3211. Specifically, the plugging protrusion 3211 and the plugging groove 3212 can be set as magnetic attraction to enhance the stability and convenience of plugging.

[0034] Preferably, such as Figure 6As shown, the outer wall of the connecting shaft 321 has several connecting screw holes 3213 axially formed, and the end of the flattening support rod 322 has a protruding connecting stud 3221 that is threadedly connected to the connecting screw holes 3213; the flattening support rod 322 is threadedly connected to the connecting screw holes 3213 at different heights on the connecting shaft 321 through the connecting stud 3221 thereon, so as to adjust the distance between the flattening support rod 322 and the hollow plate 340; during the rock geological logging process, the size of the rock cuttings will vary due to geological conditions, drilling technology and other factors. For smaller rock chips, the spacing can be appropriately reduced; for larger rock chips, the applicability of the device can be improved; reasonably adjusting the distance between the leveling support rod 322 and the perforated plate 340 can also reduce excessive friction and collision between rock chips and the perforated plate 340 and the leveling support rod 322, thereby reducing the wear and tear on the equipment; when a leveling support rod 322 is damaged or needs to be replaced, the damaged part can be quickly disassembled and replaced without replacing the entire leveling component 320, which reduces maintenance costs and equipment downtime, and improves the maintenance efficiency of the equipment.

[0035] Preferably, such as Figure 3 and Figure 5 As shown, a central hole is provided at the center of the perforated plate 340 for the connecting shaft 321 to pass through. The central hole provides a precise insertion position for the connecting shaft 321, making the assembly between the connecting shaft 321 and the perforated plate 340 more convenient and quick. When installing the flattening component 320, simply align the connecting shaft 321 with the central hole and insert it; no complicated alignment operation is required, improving assembly efficiency. The design of the central hole allows the connecting shaft 321 to pass through the center of the perforated plate 340, enabling the flattening support rod 322 on the connecting shaft 321 to act on the rock debris on the perforated plate 340 to the greatest extent.

[0036] Preferably, such as Figures 3 to 5 As shown, the perforated plate 340 is detachably connected to the inner wall of the drying drum 300; multiple support blocks 330 are protruding from the inner wall of the drying drum 300, and each support block 330 has a positioning protrusion on its top side. Multiple positioning holes corresponding to the positioning protrusions are provided on the perforated plate 340. The detachable connection between the perforated plate 340 and the inner wall of the drying drum 300 makes the installation and removal of the perforated plate 340 simple and quick, reduces downtime, improves work efficiency, and facilitates regular cleaning. Cleaning and maintenance; the support block 330 and positioning protrusion on the inner wall of the drying drum 300 cooperate with the positioning holes on the perforated plate 340 to ensure the accurate positioning and support of the perforated plate 340 during installation, which can effectively prevent the perforated plate 340 from shifting or shaking during use; at the same time, the insertion of the support block 330 and the perforated plate 340 can be quickly connected and disassembled. Specifically, the support block 330 and the perforated plate 340 can be set to be magnetically attracted to each other to improve the stability of the perforated plate 340 after installation.

[0037] Preferably, such as Figures 1 to 5 As shown, a cover 360 is detachably connected to the top of the drying drum 300; when the cover 360 is removed, the aforementioned perforated plate 340 and flattening component 320 can be easily removed, and the interior of the drying drum 300 can also be cleaned and maintained; when the cover 360 is installed, it can effectively prevent external dust and debris from entering the drying drum 300 from the top, avoiding adverse effects on the drying process; specifically, multiple limiting protrusions 350 are provided on the outer wall of the drying drum 300. The cover 360 has multiple limiting protrusions 350 and limiting grooves 361 on its edge. When the cover 360 is fitted onto the outer wall of the drying barrel 300, the limiting protrusions are inserted into the limiting grooves 361 and rotated to connect the cover 360 to the drying barrel 300, making installation and disassembly convenient. More specifically, the cover 360 can be provided with a breathable perforated part that connects the ventilated drying barrel 300 to the external space, which can accelerate the air circulation inside the drying barrel 300.

[0038] Preferably, such as Figure 4 and Figure 5 As shown, the outer wall of the drying barrel 300 is provided with an air duct 370 that communicates with its interior. The air duct 370 is used to supply air into the drying barrel 300. By supplying air into the drying barrel 300 through the air duct 370, the air flow speed inside the drying barrel 300 can be significantly increased, accelerating the evaporation and dissipation of moisture on the surface of the rock chips, thereby shortening the drying time and improving the drying efficiency. The design of the air duct 370 allows the drying barrel 300 to be easily connected to different air source equipment, such as blowers, air conditioning systems, or heated air systems. Of course, a fan can also be installed directly inside the air duct 370. The appropriate air source can be selected according to actual needs, which can flexibly adapt to different drying scenarios and conditions.

[0039] Preferably, such as Figures 1 to 5As shown, the geological logging cuttings drying device also includes a movable base 100, on which the drying barrel 300 is hinged. After drying, by tilting the drying barrel 300, the cuttings in the drying chamber 302 can be quickly poured out from the feed inlet 380 by gravity. This unloading method does not require additional tools or equipment, is simple to operate, and saves time and effort. The unloading process is simple and direct, without complicated operating steps. Of course, the cover 360 can also be opened and the perforated plate 340 removed for unloading. Specifically, the movable base 100 includes a base plate 110, with multiple casters 140 connected to the bottom side of the base plate 110 for easy movement of the entire device. Multiple support columns 120 are fixedly connected to the top of the base plate 110, and a top plate 130 is fixed to the top of the support columns 120, forming a solid structure. The movable base allows the device to be moved flexibly to the work area. The support column 120 can be a telescopic rod as in the prior art, which can adjust the height of the drying barrel 300 and improve the practicality of the device. The top plate 130 is provided with a hinge block 131, which has a hinge hole. A movable plate 200 is fixedly connected to the bottom side of the drying barrel 300. Two hinge support rods 220 are provided at one end of the movable plate 200. A hinge rod passing through the hinge hole is fixedly connected to the opposite side of the two hinge support rods 220, thereby hingedly connecting the movable plate 200 to the movable base 100, and thus hingedly connecting the drying barrel 300 to the movable base 100. A handle 210 is fixedly connected to the movable plate 200, which makes it convenient for the staff to control the movable plate 200 and the drying barrel 300 to tilt and shake.

[0040] Preferably, such as Figure 2 and Figure 4 As shown, the bottom of the drying barrel 300 is provided with a drainage hole 400; during the drying process of rock chips, the water released from the rock chips can be discharged in time through the drainage hole 400 to prevent water from accumulating at the bottom of the drying barrel 300 and affecting the drying effect; specifically, the above-mentioned movable plate 200 and top plate 130 are provided with drainage holes 400 corresponding to the drainage holes 400 on the drying barrel 300.
