Description

Technical Field

[0001] This utility model relates to the field of drilling cuttings technology, specifically a drilling cuttings raw material feeding and screening mechanism. Background Technology

[0002] The feeding, screening, and thermal desorption of drilling cuttings is a continuous workflow. First, the cuttings are collected, transported, crushed, screened, and washed. Then, thermal desorption technology separates the oil from the cuttings, achieving oil recovery and ensuring the oil content of the residue meets standards. This process effectively handles drilling cuttings, enabling resource recycling and environmental protection. The cuttings are screened to separate cuttings of different particle sizes to meet the needs of various processing techniques. A drilling cuttings classification and screening device described in patent publication number CN215088887U involves a screening plate initially in a horizontal state. The height of one end of the guide plate near the fine cuttings cavity is lower than the other end, allowing the cuttings screened off to flow into the fine cuttings cavity through the guide plate. After screening, large pieces of cuttings remain on the screening plate. At this point, the cylinder contracts, causing the screening plate to rotate downwards. The sieve plate rotates, pressing down on the guide plate via a connecting rod. This causes the guide plate to rotate and change its tilt direction, making the height of the end of the guide plate near the coarse rock fragment cavity lower than the other end. At this point, the sieve plate is also tilted, causing large rock fragments on the sieve plate to fall onto the guide plate and finally into the coarse rock fragment cavity. This achieves the classification and collection of rock fragments, facilitating the obtaining of rock fragment samples of different sizes. It also facilitates the rational processing and utilization of the classified rock fragments. A blower further sieves the rock fragment powder, blowing it into a collection box as it falls onto the sieve plate, thus achieving the classification and collection of rock fragment powder and preventing powder from falling into the fine sieve cavity. However, after prolonged use, some residual rock fragments may clog the sieve plate's sieve holes, affecting subsequent screening and classification of rock fragments.

[0003] Based on this, a drilling cuttings material feeding and screening mechanism is provided, which can eliminate the drawbacks of existing mechanisms. Utility Model Content

[0006] A drilling cuttings material feeding and screening mechanism includes a housing. Two partitions are fixedly installed inside the housing, dividing its internal space into a distribution chamber, a linkage chamber, and a screening chamber. A first discharge port is located at the bottom of the distribution chamber, and a second discharge port is located at the middle of the bottom of the screening chamber. A second outer cylinder and a first outer cylinder are rotatably installed inside the housing. A limiting lock block is fixedly installed on the outer wall of the second outer cylinder, and an electric push rod corresponding to the limiting lock block is fixedly installed on the outer wall of the first outer cylinder. An inner screen cylinder is fixedly installed inside the first and second outer cylinders. An installation groove is located at the right end of the inner screen cylinder, and an installation block is rotatably installed inside the installation groove. One end of the installation block is fixedly connected to a feed pipe.

[0007] It also includes a drive assembly, which is disposed inside the linkage cavity and is used to drive the first outer cylinder, the second outer cylinder and the inner screen cylinder to rotate;

[0008] A cleaning assembly is disposed between a first outer cylinder, a second outer cylinder, and an inner screen cylinder, and is used to clean the raw materials remaining inside the screen holes of the inner screen cylinder;

[0009] A transport assembly, disposed inside the inner screen cylinder, is used to transport raw materials;

[0010] A buffer assembly is disposed at the bottom of the housing and is used to buffer the vibrations generated during the operation of the assembly.

[0011] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0012] In one alternative: the drive assembly includes a drive motor mounted on the top left end of the housing, the output end of the drive motor extending into the linkage cavity and fixedly connected to a drive gear, the drive gear meshing with a driven gear, and the driven gear fixedly mounted on the outer wall of the first outer cylinder.

[0013] In one alternative: the cleaning assembly includes a mounting ring groove, which is located inside the right end of the second outer cylinder. A mounting ring is slidably connected inside the mounting ring groove. The mounting ring is fixedly installed on the outer wall of the water ring. Several nozzles are arranged in a circular array on the left end of the water ring. The inside of the water ring is connected to a water inlet device through a water inlet pipe.

[0014] In one alternative: the transport assembly includes a rotating motor, which is installed at the middle of the left end of the outer side of the housing. The output end of the rotating motor extends into the inner screen cylinder and is fixedly connected to a rotating rod. A transport blade is fixedly installed on the outer wall of the rotating rod.

[0015] In one alternative embodiment: the buffer assembly includes several support rods, all of which are fixedly installed at the bottom corner of the housing.

[0020] 1. This utility model, through its cleaning component, ensures that the screen holes of the inner screen cylinder are not blocked by raw material residues through timely cleaning. If the screen holes are blocked, the raw materials cannot be effectively screened out, thus affecting the efficiency and accuracy of the screening work.

[0021] 2. This utility model utilizes buffer components and rubber pads. The damping springs play a crucial role in reducing the resonance amplitude within the mechanical structure, resulting in smoother structural vibration and effectively preventing displacement of the entire structure on the ground due to vibration. Simultaneously, the rubber pads, with their excellent shock absorption and cushioning properties, significantly reduce vibration and impact generated during operation. These rubber pads are typically installed at the bottom of the support base, effectively isolating and reducing vibration and noise transmitted from the ground. Furthermore, their bottoms are designed with anti-slip textures, which greatly increase the coefficient of friction between the rubber pads and the ground, thereby ensuring the stability of the entire structure during operation, preventing movement caused by vibration, and guaranteeing the smooth progress of raw material screening.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-9 As shown, a drilling cuttings material feeding and screening mechanism includes a housing 11. Two partitions are fixedly installed inside the housing 11, dividing the internal space of the housing 11 into a material distribution chamber 17, a linkage chamber 18, and a screening chamber 19. The material distribution chamber 17 has a first discharge port 20 at its bottom end, and the screening chamber 19 has a second discharge port 21 at the middle of its bottom end. A second outer cylinder 27 and a first outer cylinder 25 are rotatably installed inside the housing 11. A limiting lock block 28 is fixedly installed on the outer wall of the second outer cylinder 27, and an electric push rod 29 corresponding to the limiting lock block 28 is fixedly installed on the outer wall of the first outer cylinder 25. An inner screen cylinder 30 is fixedly installed inside the first outer cylinder 25 and the second outer cylinder 27. An installation groove 36 is opened at the right end of the inner screen cylinder 30, and an installation block 37 is rotatably installed inside the installation groove 36. One end of the installation block 37 is fixedly connected to the feed pipe 31.

[0034] It also includes a drive assembly, which is disposed inside the linkage cavity 18 and is used to drive the first outer cylinder 25, the second outer cylinder 27 and the inner screen cylinder 30 to rotate.

[0035] A cleaning assembly is disposed between the first outer cylinder 25, the second outer cylinder 27 and the inner screen cylinder 30, and is used to clean the raw materials remaining in the screen holes of the inner screen cylinder 30.

[0036] A transport assembly, which is disposed inside the inner screen cylinder 30, is used to transport raw materials;

[0037] A buffer assembly is disposed at the bottom of the housing 11 to buffer the vibrations generated during the operation of the assembly.

[0038] In this embodiment, the operator feeds the raw material into the inner screen cylinder 30 via 31. Then, the drive assembly drives the first outer cylinder 25, the second outer cylinder 27, and the inner screen cylinder 30 to rotate simultaneously. Under the action of centrifugal force, the fine raw material enters the space between the first outer cylinder 25, the second outer cylinder 27, and the inner screen cylinder 30 through the screen holes on the inner screen cylinder 30. The remaining raw material is transported to the distribution chamber 17 by the transport assembly and discharged through the first discharge port 20 at the bottom of the distribution chamber 17. By moving the electric push rod 29 away from the limiting lock block 28, the holes of the first outer cylinder 25 and the second outer cylinder 27 are opened, and the fine raw material enters the screening chamber 19 through the holes and is finally discharged through the second discharge port 21 at the bottom of the screening chamber 19. When the structure is running, the buffer assembly starts to work, and the vibration generated by the buffer assembly is absorbed. After screening is completed, the operator washes the remaining raw material in the screen holes of the inner screen cylinder 30 using the cleaning assembly.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, the drive assembly includes a drive motor 23, which is mounted on the top left end of the housing 11. The output end of the drive motor 23 extends into the linkage cavity 18 and is fixedly connected to the drive gear 24. The drive gear 24 is meshed with the driven gear 26, which is fixedly mounted on the outer wall of the first outer cylinder 25.

[0040] The drive motor 23 drives the drive gear 24 to rotate. Since the drive gear 24 is meshed with the driven gear 26, the drive gear 24 drives the driven gear 26 to rotate when it rotates. The driven gear 26 is fixedly installed on the outer wall of the first outer cylinder 25. Since the first outer cylinder 25, the second outer cylinder 27, and the inner screen cylinder 30 are designed as a whole, the first outer cylinder 25, the second outer cylinder 27, and the inner screen cylinder 30 rotate synchronously, thereby allowing the raw materials inside the inner screen cylinder 30 to be screened under the action of centrifugal force.

[0041] In one embodiment, such as Figure 6 and Figure 7 As shown, the cleaning assembly includes an installation ring groove 32, which is opened at the right end inside the second outer cylinder 27. An installation ring 33 is slidably connected inside the installation ring groove 32. The installation ring 33 is fixedly installed on the outer wall of the water ring 34. Several nozzles 35 are arranged in a circular array at the left end of the water ring 34. The inside of the water ring 34 is connected to the water inlet device through a water inlet pipe.

[0042] Workers connect the water inlet device through the water inlet pipe, and clean water enters the water ring 34 through the water inlet pipe. The clean water inside the water ring 34 is sprayed out through the nozzle 35, and the clean water washes the inner screen cylinder 30 to prevent the raw materials remaining inside the screen holes of the inner screen cylinder 30 from affecting the subsequent raw material screening work.

[0043] In one embodiment, such as Figure 3 and Figure 8 As shown, the transport assembly includes a rotating motor 38, which is installed at the middle of the left end of the outer side of the housing 11. The output end of the rotating motor 38 extends into the inner screen cylinder 30 and is fixedly connected to a rotating rod 39. A transport blade 40 is fixedly installed on the outer wall of the rotating rod 39.

[0044] The rotating rod 39 is driven to rotate by the rotating motor 38. Since the transport blade 40 is fixedly installed on the outer wall of the rotating rod 39, the rotating rod 39 rotates and drives the transport blade 40 to rotate, thereby transporting the raw material inside the inner screen cylinder 30 to the first discharge port 20 at the bottom of the distribution chamber 17 for discharge.

[0045] In one embodiment, such as Figure 2 and Figure 9 As shown, the buffer assembly includes several support rods 12, all of which are fixedly installed at the bottom corner of the housing 11. The bottom end of each support rod 12 is fixedly connected to a limiting block 13. The outer wall of the limiting block 13 is slidably connected to the inner wall of the slide cylinder 14. A damping spring 15 is installed inside the slide cylinder 14. The upper end of the damping spring 15 is fixedly connected to the lower end of the limiting block 13, and the lower end of the damping spring 15 is fixedly connected to the inner wall of the slide cylinder 14. The bottom end of the slide cylinder 14 is fixedly connected to a support base 16.

[0046] The structure will vibrate during operation. The damping spring 15 can effectively reduce the resonance amplitude in the mechanical structure, making the structural vibration more stable and preventing the overall structure from shifting on the ground.

[0047] In one embodiment, such as Figure 3 As shown, inclined blocks 22 are symmetrically fixed at the bottom of the screening cavity 19.

[0048] By symmetrically fixing inclined blocks 22 at the bottom of the screening chamber 19, the discharge angle of the raw material can be adjusted, which is beneficial to the discharge of the raw material.

[0049] In one embodiment, such as Figure 5 As shown, the mounting groove 36 and the mounting block 37 have a T-shaped cross-section.

[0050] The mounting groove 36 and the mounting block 37 have a T-shaped cross-section, which makes them less likely to separate, thereby preventing the inner screen cylinder 30 from separating from the feed pipe 31, and ensuring that the raw material can enter the inner screen cylinder 30 through the feed pipe 31.

[0051] In one embodiment, such as Figure 9 As shown, a rubber pad is fixedly installed at the bottom of the support base 16, and the bottom of the rubber pad is provided with anti-slip texture.

[0052] The rubber pad has good shock absorption and cushioning performance, which can effectively reduce the vibration and impact generated by the structure during operation. The rubber pad is located at the bottom of the support 16, which can effectively reduce the vibration and noise transmitted from the ground. The bottom of the rubber pad is provided with anti-slip texture, which helps to increase the friction coefficient of the bottom of the rubber pad, thereby increasing the friction between the bottom of the rubber pad and the ground, thus preventing the overall structure from moving and affecting the raw material screening.

[0053] The above embodiment discloses a drilling cuttings material feeding and screening mechanism. In this mechanism, the operator feeds the material into the inner screen cylinder 30 via 31. Then, a drive motor 23 drives the drive gear 24 to rotate. Since the drive gear 24 meshes with the driven gear 26, the drive gear 24 rotates, causing the driven gear 26 to rotate as it rotates. The driven gear 26 is fixedly installed on the outer wall of the first outer cylinder 25. Because the first outer cylinder 25, the second outer cylinder 27, and the inner screen cylinder 30 are integrated, they rotate synchronously. Under centrifugal force, fine material passes through the screen holes on the inner screen cylinder 30 and enters between the first outer cylinder 25, the second outer cylinder 27, and the inner screen cylinder 30. The remaining material is driven by a rotating motor 38 to rotate a rotating rod 39. Since a transport blade 40 is fixedly installed on the outer wall of the rotating rod 39, the rotating rod... When the 39 rotates, it drives the transport blade 40 to rotate, thereby transporting the raw material inside the inner screen cylinder 30 to the first discharge port 20 at the bottom of the distribution chamber 17 for discharge. The remaining raw material is discharged through the first discharge port 20 at the bottom of the distribution chamber 17. By moving the electric push rod 29 away from the limit lock block 28, the holes of the first outer cylinder 25 and the second outer cylinder 27 are opened, and the fine raw material enters the screening chamber 19 through the holes and is finally discharged through the second discharge port 21 at the bottom of the screening chamber 19. When the structure is running, the damping spring 15 reduces the resonance amplitude in the mechanical structure, making the structure vibrate more smoothly. After screening, the staff connects the water inlet device through the water inlet pipe, and clean water enters the water ring 34 through the water inlet pipe. The clean water inside the water ring 34 is sprayed out through the nozzle 35, and the clean water washes the inner screen cylinder 30 to prevent the raw material remaining inside the screen holes of the inner screen cylinder 30 from affecting the subsequent raw material screening work.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
