Description

Technical Field

[0001] This utility model relates to the field of cuttings drying technology, and in particular to a high-efficiency drilling cuttings drying and recovery device. Background Technology

[0002] Because drilling operations generate a large amount of oil- and water-containing rock cuttings, direct discharge of such cuttings can easily cause soil and water pollution. Furthermore, the unutilized drilling fluid components in the cuttings represent a waste of resources and do not comply with environmental regulations for solid waste treatment. Therefore, drilling cuttings drying and recycling devices are established to remove oil and water from the cuttings and recover recyclable drilling fluid components, thereby achieving the reduction, harmless treatment, and resource recovery of the cuttings.

[0003] A search revealed Chinese patent publication number CN221256702U, which discloses an oil drilling cuttings dryer, belonging to the field of oil drilling technology. The dryer includes a support frame, with a housing fixedly connected to its top. A limiting groove is formed on the top of the housing, and a screen cylinder is fixedly connected to its top. A protective shell is fixedly connected to the outer surface of the housing, and a feed inlet is formed on the top of the screen cylinder. Its advantages are: by incorporating a screen cylinder, a first motor, a first rotating shaft, and a scraper, it facilitates pushing the cuttings to be processed for drying; by incorporating a protective shell, a water outlet, a placement frame, and a processing box, it collects the water ejected from the cuttings for convenient unified processing; by incorporating a second motor, a threaded rod, a threaded cylinder, and a pushing frame, it facilitates the release of the dried cuttings; and by incorporating a third motor, a second rotating shaft, and a baffle, it facilitates the ejection of cuttings from the baffle.

[0004] The aforementioned patent has the following shortcomings: Since the screens of existing devices mostly adopt a fixed installation structure, it is necessary to disassemble the equipment housing and loosen multiple fastening parts when replacing screens with different aperture sizes. Moreover, the operation process requires the cooperation of professional personnel, which makes it inconvenient to adjust the aperture size according to the changes in rock cuttings particle size. This leads to problems such as screen clogging or incomplete separation during operation, reducing drying and recovery efficiency and making it difficult to adapt to the differentiated needs of rock cuttings processing under different drilling conditions.

[0005] Therefore, a highly efficient drilling cuttings drying and recovery device is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide an efficient drilling cuttings drying and recovery device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model embodiment is implemented as follows: a high-efficiency drilling cuttings drying and recovery device, including a support frame, and further comprising: The box body is fixed inside the support frame. The bottom of the box body is rotatably connected to a spin-drying cone. The outer side of the spin-drying cone is fitted with a first screen connected to the box body. The top of the box body is fixed with a feed hopper. A splash guard structure to prevent rock debris and wastewater from splashing outwards is installed at the top inside the feed hopper; A crushing structure for crushing large volumes of rock cuttings is located at the bottom of the feed hopper.

[0010] In some embodiments: the side of the push arm away from the screw is rotatably connected to one of a set of reinforcing bars, the reinforcing bars being arranged in a ring at equal intervals on the outer side of the second screen.

[0011] In some embodiments: the splash-proof structure includes connecting hinges fixed to both sides inside the feed hopper, a baffle is installed on one side of the connecting hinge, a first rotating seat is installed on both sides of the bottom end of the baffle, a return spring is installed on the rotating end of the first rotating seat, and a second rotating seat is installed on the side of the return spring away from the first rotating seat.

[0012] In some embodiments: the baffles form a rotating structure with the feed hopper via connecting hinges, and the baffles are symmetrically distributed on the vertical center line of the feed hopper.

[0013] In some embodiments: the crushing structure includes a crushing sleeve fixed to the bottom of the inside of the feed hopper, a drive shaft fixed to the top of the spin-drying cone, a crushing cylinder fixed to the outside of the drive shaft, and a limiting seat rotatably connected to the top of the crushing cylinder and fixedly connected to the feed hopper.

[0014] In some embodiments: the frontal cross-section of the inner wall of the crushing sleeve has a funnel-shaped inclined structure, and crushing teeth are fixed on the surfaces of both the crushing sleeve and the crushing cylinder.

[0015] The present invention has the following advantages due to the adoption of the above technical solution: 1.

Detailed Implementation

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1: As Figures 1 to 5 As shown, a high-efficiency drilling cuttings drying and recovery device includes a support frame 1, and further includes: Box 2 is fixed inside the support frame 1. The bottom of the box 2 is rotatably connected to a spin-drying cone 11. The outside of the spin-drying cone 11 is fitted with a first screen 15 connected to the box 2. The top of the box 2 is fixed with a feed hopper 5. A splash guard 6, used to prevent rock debris and wastewater from splashing outwards, is installed at the top inside the feed hopper 5. The crushing structure 9, used for crushing large volume rock cuttings, is located at the bottom of the feed hopper 5. A variable diameter structure 4 is provided on the outside of the first screen 15. The variable diameter structure 4 includes a second screen 401 rotatably connected to the outside of the first screen 15. A reinforcing strip 402 is fixed on the outside of the second screen 401. A movable component is provided on one side inside the box 2.

[0026] A drain pipe 3 is fixed to the bottom of one side of the box body 2, and a slag discharge pipe 14 is fixed to one side of the bottom of the box body 2. A second transmission wheel 13 is installed at the rotating end of the spin-drying cone 11. An installation plate 10 is fixed to one side inside the support frame 1. A reducer 8 is installed at the top of the installation plate 10. A drive motor 7 is fixed to the end of the input shaft of the reducer 8. A first transmission wheel 12 is installed at the end of the output shaft of the reducer 8, and the first transmission wheel 12 is connected to the second transmission wheel 13 through a transmission belt.

[0027] In this embodiment, the drive motor 7 is started and driven by the reducer 8 to rotate the first transmission wheel 12. Then, the first transmission wheel 12 drives the second transmission wheel 13 to rotate through the transmission belt, thereby driving the spin-drying cone 11 to rotate at high speed and generate centrifugal force. The rock chips enter the box 2 through the feed hopper 5 and fall onto the surface of the spin-drying cone 11. Through the action of centrifugal force, the water in the rock chips passes through the screen gap between the first screen 15 and the second screen 401. Then, the water is discharged through the drain pipe 3. The solid rock chips fall and are discharged through the slag discharge pipe 14 under the rotation of the spin-drying cone 11, so that the rock chips achieve solid-liquid separation.

[0028] like Figures 1 to 4 As shown, the moving component includes a fixed housing 403 fixed inside one side of the housing 2. A screw 405 is threadedly connected inside the fixed housing 403. A push arm 404 is rotatably connected to one side of the screw 405. A crank 406 is fixed to the other side of the screw 405. The side of the push arm 404 away from the screw 405 is rotatably connected to one of the reinforcing bars 402. The reinforcing bars 402 are arranged in a ring at equal intervals on the outer side of the second screen 401.

[0029] In this embodiment, when it is necessary to adjust the screen aperture according to the rock cutting particle size, the screw 405 is rotated by turning the crank handle 406. The screw 405 pushes the push arm 404 to move through the thread on the inner wall of the fixed shell 403. Then, the push arm 404 drives the reinforcing strip 402 to push the second screen 401 to rotate. This causes the screen gaps of the second screen 401 and the first screen 15 to be misaligned, so that the overall aperture of the screen changes, adapting to the separation requirements of rock cuttings of different particle sizes and avoiding the problems of screen clogging or incomplete separation.

[0030] Example 2: A high-efficiency drilling cuttings drying and recovery device. This example is based on Example 1 with the following improvements, such as... Figures 1 to 5 As shown, the splash-proof structure 6 includes connecting hinges 604 fixed inside both sides of the feed hopper 5. A baffle 601 is installed on one side of the connecting hinge 604. First rotating seats 602 are installed on both sides of the bottom end of the baffle 601. A return spring 603 is installed on the rotating end of the first rotating seat 602. A second rotating seat 605 is installed on the side of the return spring 603 away from the first rotating seat 602. The baffle 601 forms a rotating structure with the feed hopper 5 through the connecting hinges 604. The baffle 601 is symmetrically distributed on the vertical center line of the feed hopper 5.

[0031] In this embodiment, when rock cuttings enter the device from the feed hopper 5, the rock cuttings impact the baffle 601 due to their own weight, causing the baffle 601 to rotate and open around the connecting hinge 604. Then, the rock cuttings enter the subsequent processing stage. The rock cuttings pass through the rear reset spring 603, which pushes the baffle 601 to reset and close, so that the feed hopper 5 remains in a relatively closed state, which to a certain extent prevents rock cuttings and wastewater from splashing out and avoids pollution of the working environment.

[0032] like Figures 1 to 2 As shown, the crushing structure 9 includes a crushing sleeve 902 fixed inside the bottom of the feed hopper 5, a drive shaft 901 fixed to the top of the drying cone 11, a crushing cylinder 903 fixed to the outside of the drive shaft 901, a limiting seat 904 fixedly connected to the top of the crushing cylinder 903 and the feed hopper 5, and the front cross-section of the inner wall of the crushing sleeve 902 is a funnel-shaped inclined structure. Crushing teeth are fixed on the surfaces of both the crushing sleeve 902 and the crushing cylinder 903.

[0033] In this embodiment, when large volume rock cuttings enter the bottom of the feed hopper 5, the drive shaft 901 is rotated by the spin-drying cone 11. At the same time, the drive shaft 901 drives the crushing cylinder 903 to rotate synchronously. Then, the crushing teeth on the surface of the crushing cylinder 903 mesh with the crushing teeth on the inner wall of the crushing sleeve 902, thereby squeezing and crushing the large volume rock cuttings, reducing the volume of the large volume rock cuttings.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
