Description

Technical Field

[0001] The present invention relates to the technical field of oil drilling equipment, and in particular to a device for processing waste drilling materials. Background Art

[0002] In the field of oil drilling engineering, the treatment of waste drilling materials has always been an important link facing many challenges and urgently in need of optimization. Traditional treatment methods and related equipment have obvious limitations and shortcomings.

[0003] In the early days, the waste drilling materials were mostly treated by simple extensive methods such as natural sedimentation and stacking. Although natural sedimentation can settle some solid particles, it takes a very long time, and it is difficult to effectively separate some fine particles and impurities that are tightly bound to chemical agents, resulting in the waste drilling materials still containing a large amount of pollutants after treatment. If they are randomly stacked later, they are likely to cause serious pollution to the surrounding environment such as soil and groundwater, which does not meet the increasingly stringent environmental protection requirements.

[0004] With the development of technology, some conventional mechanical separation equipment, such as centrifuges, have begun to be used for treatment. However, when centrifuges are used to treat waste drilling materials, the separation effect is often not ideal for mud with complex composition, high viscosity and multiple chemical residues. On the one hand, it is difficult to completely separate solid particles of different particle sizes and properties. On the other hand, it is also impossible to effectively remove the chemicals in the mud, so that the treated waste drilling materials still do not meet the standards for subsequent disposal or reuse. Other treatment methods need to be further adopted, which increases the complexity and cost of treatment.

[0005] In the drying process, the common drying equipment used in the past usually operates at a relatively high temperature. Although this high-temperature drying method can quickly remove moisture, it is easy to cause some heat-sensitive components and residual chemicals in the abandoned drilling materials to change their properties, decompose, and even produce harmful gases, which not only affects the quality of the treated materials, but also may bring new environmental pollution problems, and also increase energy consumption, which is not in line with the development trend of energy conservation and emission reduction.

[0006] In terms of water recycling, under traditional treatment technologies, such as the plate and frame filter press treatment method mentioned above, due to its limited mud types, it has serious defects in the separation of salt and water when facing the common saturated brine mud in practice. This results in the recycled water containing a large amount of salt and cannot be directly reused. It must go through an additional complex purification process, which consumes a lot of manpower, material and financial resources, not only reducing the treatment efficiency, but also greatly reducing the economic efficiency of the entire abandoned drilling material treatment process.

[0007] Moreover, traditional processing systems often lack integrity and coordination, and the connections between various processing links are not tight enough. When materials and gases flow between different equipment, they are prone to blockage, unstable pressure and other problems, which affect the normal operation of the equipment and require frequent shutdowns for maintenance and debugging, further reducing the continuity and reliability of the processing. It is difficult to meet the actual needs of large-scale and efficient processing of abandoned drilling materials. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0023] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0024] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, proposes an abandoned drilling material processing device, including a mud receiving part 1, the mud receiving part 1 leads to a mixer 2, a dosing part 3 leads to the mixer 2, the mixer 2 leads to a low-temperature dryer 4, the low-temperature dryer 4 leads to a condenser 5, and the condenser 5 leads to a vacuum pump 6.

[0027] In this embodiment, the mud receiving part 1, as the starting part of the entire waste drilling material processing device, undertakes the important task of collecting waste drilling mud. After the drilling operation is completed, a large amount of waste mud containing various impurities, solid particles and chemical residues will be generated. The mud receiving part 1 can uniformly collect these waste muds from different drilling sites and under different working conditions, providing a stable source of materials for the subsequent processing process, ensuring that the entire processing device can continuously and effectively process the waste drilling materials.

[0028] The mixer 2 receives the waste mud from the mud receiving part 1 and the reagent added by the dosing part 3. Its core function is to mix the two materials fully and evenly. Through the rotation of the internal stirring device (such as a stirring paddle, spiral blades, etc.), the waste mud and the reagent break the original agglomeration state under the action of mechanical force, and achieve better uniform dispersion and mixing. A good mixing effect can significantly improve the treatment efficiency and treatment quality of the entire waste drilling material treatment device. When the waste mud and the reagent are fully mixed, the reagent can more comprehensively contact the various components in the mud and play its greatest role, so that the substances to be treated can be converted and removed faster, reducing the treatment time and the amount of reagent used.

[0029] The dosing unit 3 is responsible for adding specific reagents to the mixer 2, and has precise reagent metering and adding functions. According to the composition, properties and treatment objectives of the waste mud, the type, dosage and addition time of the added reagents can be accurately controlled to avoid problems such as waste of resources and increased difficulty in subsequent treatment due to excessive dosing, or poor treatment effect due to insufficient dosing, thereby improving the scientificity and economy of the entire treatment process.

[0030] Abandoned drilling materials usually contain a large amount of water. The low-temperature dryer 4 uses the heat exchange principle to gradually evaporate and remove the water in the material under a low-temperature environment, thereby achieving the reduction of the amount of abandoned drilling materials. After low-temperature drying, the volume and weight of the material are greatly reduced, which not only facilitates subsequent transportation, storage and final disposal, but also reduces potential harm to the environment and reduces the pressure of subsequent processing links, making the entire abandoned drilling material processing process more efficient and convenient, and further improving the practicality and processing capacity of the processing device.

[0031] During the process of drying the waste drilling materials by the low-temperature dryer 4, the water in the materials will turn into water vapor and evaporate. After the water vapor enters the condenser 5, the condenser 5 uses a cooling medium (such as water, refrigerant, etc.) to cool the water vapor through heat exchange to release heat, and then condense into liquid water. During the operation, the condenser 5 can also regulate and stabilize the system pressure of the entire processing device by condensing the water vapor. If a large amount of water vapor accumulates in the system, it will cause the system pressure to rise and affect the normal operation of each device. The condenser 5 condenses the water vapor into liquid and discharges it in time, maintaining a relatively stable pressure environment in the system, ensuring the smooth flow of materials and gases between the mud receiving part 1, the mixer 2, the low-temperature dryer 4 and other components, avoiding equipment failures and material leakage caused by abnormal pressure. Safety issues such as improve the operation stability and reliability of the entire waste drilling material processing device. The vacuum pump 6 is connected to the condenser 5, and its main function is to extract the gas in the system to create a negative pressure environment.

[0032] In traditional waste drilling material treatment technology, plate and frame filter presses are often used to separate mud and water from mud. However, existing plate and frame filter presses are mainly used to separate mud and water from polymer mud, while the mud currently faced is mostly saturated brine mud and contains a large amount of industrial salt. This characteristic makes it impossible for existing plate and frame filter presses to effectively separate salt and water when treating such mud. As a result, the recycled water contains a large amount of salt and cannot be used directly. It also requires additional treatment processes to purify it, which not only increases the treatment cost, but also reduces the treatment efficiency.

[0033] In sharp contrast, the waste drilling material processing device innovatively uses a vacuum pump 6 to separate the materials in the low-temperature dryer 4. Under the negative pressure environment created by the vacuum pump 6, the water in the material is easier to evaporate, and under the action of the condenser 5, the steam can be efficiently condensed into liquid water. Through this innovative treatment method, the purity of the water condensed by the condenser 5 is greatly improved, and it can be directly reused. This remarkable effect not only solves the problem that the recycled water cannot be used directly in traditional technologies, but also realizes the recycling of water resources, greatly reduces the water cost in the process of waste drilling material treatment, and improves the environmental protection and resource utilization of the entire treatment process. At the same time, it avoids the limitations caused by the use of plate ore filter presses, and provides a more efficient and environmentally friendly solution for the treatment of waste drilling materials.

[0034] Furthermore, the low-temperature dryer 4 includes a housing 401 having a drying chamber 402 , a rotating member 403 rotatably disposed in the drying chamber 402 , the rotating member 403 having a plurality of isolation chambers 404 , four isolation chambers 404 arranged in a circle, and a swinging member 405 swingably disposed on the chamber wall of the isolation chamber 404 .

[0035] In this embodiment, the isolation chamber 404 is specifically used for the sedimentation of mud, providing a physical space for the effective separation of mud and solution. When the mixed materials enter the isolation chamber 404, under the action of gravity, the solid phase particles (such as silt, clay, etc.) in the mud will gradually sink, while the solution will gradually float up, thereby achieving preliminary solid-liquid separation. Since there are four isolation chambers 404 and they are arranged in a circle, each isolation chamber 404 can perform sedimentation and separation operations in turn under the drive of the rotating member 403, which greatly improves the separation efficiency, so that the low-temperature dryer 4 can process more materials per unit time, meeting the needs of large-scale waste drilling material processing. Different batches of materials are precipitated and separated simultaneously in different isolation chambers 404, avoiding the fluctuation of separation effect caused by material mixing or discontinuous processing flow. Each isolation chamber 404 can be regarded as an independent separation unit, and its sedimentation environment is relatively stable and less affected by external interference, thereby ensuring that each separation operation can achieve a relatively consistent effect, providing a reliable basis for the subsequent further processing of the separated mud and solution.

[0036] After the swinging member 405 swings, the area of ​​the isolation chamber 404 can be reduced. This design cleverly solves the problem of discharging mud residue after sedimentation. After the mud has settled in the isolation chamber 404, the swinging member 405 begins to swing. As the area of ​​the isolation chamber 404 gradually decreases, the mud residue settled at the bottom will be gradually squeezed and pushed toward the mud outlet 408, which conveniently and quickly realizes the discharge of mud residue. Compared with traditional manual cleaning or complex mechanical discharge methods, this method of using the swinging member 405 to change the area of ​​the isolation chamber 404 to discharge mud residue greatly improves the mud discharge efficiency and reduces the cost of manual operation and equipment maintenance.

[0037] The structure of the low-temperature dryer 4, which is composed of the isolation chamber 404 and the swinging member 405, optimizes the performance of the equipment as a whole. The isolation chamber 404 realizes the efficient separation of mud and solution, while the swinging member 405 solves the problem of mud residue discharge. The two work together, so that the low-temperature dryer 4 can play a better role in the waste drilling material processing process. This structural design not only improves the efficiency of separation and mud discharge, but also ensures the stability of the treatment effect and the continuity of the equipment operation, and provides good conditions for the subsequent further treatment of the separated products (such as purification of the solution, reuse of the mud residue, etc.), thereby improving the processing capacity and quality of the entire waste drilling material processing device. The structure of the isolation chamber 404 and the swinging member 405 is relatively simple and easy to operate. Since the isolation chambers 404 are independent of each other, when maintaining or cleaning a certain isolation chamber 404, it will not affect the normal operation of other isolation chambers 404, thereby improving the maintenance efficiency.

[0038] Furthermore, there is a gap 406 between the swinging member 405 and the cavity wall of the isolation cavity 404, and the movable top member 7 is also included. The movable top member 7 is slidably arranged in the drying cavity 402. The movable top member 7 is configured to slide into the gap 406 after sliding and abut against the swinging member 405. After the movable top member 7 abuts against the swinging member 405, the swinging member 405 is perpendicular to the cavity wall of the isolation cavity 404. One end of the elastic member acts on the swinging member 405, and the other end acts on the cavity wall of the isolation cavity 404, providing a force to reduce the gap 406.

[0039] In this embodiment, the movable top member 7 is slidably disposed in the drying chamber 402, and can slide into the gap 406 between the swing member 405 and the wall of the isolation chamber 404 and abut against the swing member 405. This design realizes precise control of the movement of the swing member 405. When it is necessary to discharge the mud residue settled in the isolation chamber 404, the movable top member 7 slides along the preset path and accurately enters the gap 406. By abutting against the swing member 405, the swing member 405 is strongly pushed to move, so that it quickly swings from the initial state to a position perpendicular to the wall of the isolation chamber 404. Compared with other possible indirect driving methods, this precise driving method can more reliably ensure that the swing member 405 plays a role in a timely and accurate manner when needed, ensure the stability and reliability of the mud residue discharge operation, and improve the mud discharge efficiency.

[0040] When the swing member 405 is perpendicular to the wall of the isolation chamber 404 under the action of the movable top member 7, the effective area of ​​the isolation chamber 404 is rapidly reduced, forming a strong squeezing effect on the mud residue settled at the bottom. This precisely controlled area change allows the mud residue to be concentrated and efficiently pushed to the mud outlet 408, avoiding the situation of mud residue residue residue or poor discharge. One end of the elastic member acts on the swing member 405, and the other end acts on the wall of the isolation chamber 404. The force provided by the elastic member keeps the gap 406 at an appropriate size when not subject to external force, and can automatically reset after the swing member 405 moves. When the movable top member 7 slides away from the gap 406, the elastic member releases the elastic force, drives the swing member 405 to return to its initial state, and at the same time restores the gap 406 to its normal size. This automatic reset function not only saves additional mechanical reset devices and power sources, simplifies the equipment structure, and reduces the equipment cost, but also makes the action cycle of the swing member 405 smoother, and improves the automation and stability of the equipment operation.

[0041] Furthermore, it also includes a scraper 9, which is slidably set in the isolation cavity 404, and the bottom of the scraper 9 abuts against the bottom of the isolation cavity 404. The scraper 9 has a guide groove, and the cavity wall of the isolation cavity 404 has a guide part, and the guide groove is used to accommodate the guide part.

[0042] In this embodiment, the scraper 9 is slidably disposed in the isolation chamber 404, and the bottom thereof is in close contact with the bottom of the isolation chamber 404. This design can ensure that the residual mud residue at the bottom of the isolation chamber 404 is thoroughly cleaned during the mud residue discharge process. Even if there is still a small amount of residual mud residue under the squeezing action of the swinging member 405, the scraper 9 can scrape it up during the sliding process, effectively avoiding the accumulation of mud residue at the bottom of the isolation chamber 404. Especially for some mud residues with high viscosity and easy to adhere, the role of the scraper 9 is more significant, further improving the thoroughness of mud residue discharge, ensuring the cleanliness of the isolation chamber 404 after each use, and providing a good foundation for subsequent mud sedimentation and separation operations.

[0043] The scraper 9 has a guide groove, and the cavity wall of the isolation cavity 404 is provided with a guide part. The guide groove is used to accommodate the guide part. This structural design makes the scraper 9 have extremely high stability and accuracy during the sliding process. The cooperation between the guide groove and the guide part limits the movement trajectory of the scraper 9, avoids the scraper 9 from deflecting, jamming or shaking during sliding, and ensures that the scraper 9 can smoothly perform cleaning work along the predetermined route. This not only improves the working efficiency of the scraper 9, but also reduces the wear on the isolation cavity 404 caused by the abnormal movement of the scraper 9, and prolongs the service life of the equipment.

[0044] The scraper 9 cooperates with the movable top member 7, the swing member 405 and the elastic member to improve the overall performance of the low-temperature dryer 4. In the mud discharge process, the movable top member 7 drives the swing member 405 to squeeze the mud, and then the scraper 9 performs the subsequent cleaning work. The whole process is closely connected to form an efficient mud treatment system. At the same time, the stable operation of the scraper 9 also helps to maintain the structural stability in the isolation chamber 404, and corresponds to the buffering and resetting effect of the elastic member on the swing member 405, further ensuring the reliable operation of the low-temperature dryer 4 under complex working conditions, and providing more powerful support for the efficient and stable operation of the entire waste drilling material processing device.

[0045] Furthermore, the scraper 9 has a flexible deformation portion 902 , and the flexible deformation portion 902 is pressed on the swinging member 405 .

[0046] In this embodiment, the flexible deformation part 902 of the scraper 9 is pressed on the swinging member 405, and can be adaptively adjusted according to the surface shape and position changes of the swinging member 405. Since the swinging member 405 will swing during the operation, its surface state is not completely flat and fixed. The flexible deformation part 902 can fit the surface of the swinging member 405 tightly by virtue of its own flexibility, and can ensure that the mud residue attached to the swinging member 405 is effectively scraped off both in the initial position of the swinging member 405 and during the swinging process. For example, when the swinging member 405 swings to a position perpendicular to the wall of the isolation chamber 404, mud residue is likely to remain at the angle between it and the wall of the isolation chamber 404. The flexible deformation part 902 can penetrate into these angle areas through its own deformation, and completely clean up the mud residue, thereby avoiding the residue residue from remaining and improving the comprehensiveness and thoroughness of the mud residue cleaning.

[0047] Furthermore, the scraper 9 has a threaded hole 901 and also includes a screw 10, which is rotatably set in the threaded hole 901, and the end of the screw 10 has a first connecting part 1001. The sliding member 11 is slidably and rotatably set in the drying chamber 402, and the end of the sliding member 11 has a second connecting part 1101. The first connecting part 1001 is used to connect with the second connecting part 1101, and the sliding member 11 is used to drive the screw 10 to rotate.

[0048] In this embodiment, the screw 10 cooperates with the threaded hole 901 on the scraper 9, and the principle of threaded transmission is used to accurately convert the rotation of the screw 10 into the linear sliding of the scraper 9. This transmission method has extremely high precision. By controlling the rotation angle and number of turns of the screw 10, the moving distance of the scraper 9 in the isolation chamber 404 can be accurately controlled, ensuring that the mud residue at the bottom of the isolation chamber 404 is cleaned comprehensively and meticulously without leaving any corner, greatly improving the effect and quality of mud residue cleaning. For example, in the case where some fine mud residue accumulates at the edge of the isolation chamber 404, by accurately controlling the rotation of the screw 10, the scraper 9 can accurately reach these positions and thoroughly clean the mud residue.

[0049] The sliding member 11 can both slide and rotate in the drying chamber 402, and the second connecting portion 1101 at the end thereof is connected to the first connecting portion 1001 at the end of the screw 10, thereby driving the screw 10 to rotate. This design gives the operator greater operational flexibility. During the operation of the equipment, the operator can flexibly move the sliding member 11 according to the actual mud accumulation situation, select different positions and angles to drive the screw 10, and then control the operation of the scraper 9. For example, when the mud in a certain isolation chamber 404 is unevenly distributed, the operator can move the sliding member 11 to make the screw 10 drive the scraper 9 at different positions, and focus on cleaning the areas with more mud in a targeted manner to improve the cleaning efficiency. Moreover, since the operating space of the sliding member 11 is relatively large, it is more convenient and quicker than directly operating the scraper 9 in the isolation chamber 404, reducing the labor intensity and operating difficulty of the operator.

[0050] Furthermore, it also includes a rotating wheel 20, which is rotatably disposed on the housing 401, and the sliding member 11 is slidably disposed on the rotating wheel 20, and the rotating wheel 20 is used to drive the sliding member 11 to rotate.

[0051] In this embodiment, the rotating wheel 20 is rotatably arranged on the housing 401, and the sliding member 11 is slidably arranged on the rotating wheel 20. The sliding member 11 is driven to rotate by the rotating wheel 20, which provides a stable and accurate rotation transmission method for driving the scraper 9. Compared with other driving connection methods that may be more direct or simple, the rotating wheel 20 can transmit power to the sliding member 11 more evenly and smoothly, thereby ensuring that the sliding movement of the scraper 9 in the isolation chamber 404 is more stable. For example, during long-term operation, the equipment may be subject to various vibrations, external force interference, etc., and the rotation characteristics of the rotating wheel 20 can effectively buffer these unstable factors, so that the movement trajectory of the scraper 9 remains accurate, avoiding the problems of the scraper 9 being stuck or shaking due to uneven power transmission, and ensuring the smooth progress of the mud cleaning work.

[0052] In the entire working process of the low-temperature dryer 4, the movement of the scraper 9 needs to be coordinated with the movements of other components (such as the rotating member 403, the swinging member 405, etc.). The introduction of the rotating wheel 20 makes the rotation drive of the scraper 9 more orderly and can better match the operation rhythm of other components. After the rotating member 403 drives the isolation chamber 404 to perform material sedimentation and separation operations, the rotating wheel 20 can drive the sliding member 11 to rotate according to the preset time and speed, thereby driving the scraper 9 to clean up the mud residue after sedimentation in time, making the connection between the components tighter and smoother, improving the coordination and stability of the overall operation of the equipment, and optimizing the processing process of abandoned drilling materials.

[0053] Furthermore, the drying chamber 402 has an inlet 407, a mud outlet 408 and a negative pressure hole 409. The inlet 407 and the mud outlet 408 are respectively connected to two adjacent isolation chambers 404. The negative pressure hole 409 is located on the side wall of the drying chamber 402 and at the lower side of the rotating member 403. It also includes a first baffle 12. The first baffle 12 is arranged in the drying chamber 402 and is located around the rotating member 403 to form a solid-liquid separation chamber 410 with the isolation chamber 404. The first baffle 12 has a notch 1201, which is connected to the mud outlet 408.

[0054] In this embodiment, the inlet 407 and the mud outlet 408 of the drying chamber 402 are respectively connected to two adjacent isolation chambers 404. This design constructs an efficient material flow path. Abandoned drilling mud can directly enter the specific isolation chamber 404 through the inlet 407 to start the sedimentation and solid-liquid separation process. The mud residue that needs to be discharged after sedimentation can be smoothly discharged from the adjacent isolation chamber 404 through the mud outlet 408 after rotating for one circle. This adjacent setting prolongs the moving distance and time of the material in the drying chamber, avoids ensuring the sedimentation effect of the sludge, and enables the low-temperature dryer 4 to process a large amount of abandoned drilling materials more quickly.

[0055] The first baffle 12 is disposed in the drying chamber 402, surrounding the rotating member 403, and forming a solid-liquid separation chamber 410 with the isolation chamber 404. During the slurry sedimentation process in the isolation chamber 404, the solid-liquid separation chamber 410 provides a relatively closed and stable environment, which helps to reduce the interference of external factors on the sedimentation process, so that the solid phase particles in the slurry can settle to the bottom of the isolation chamber 404 more fully and quickly.

[0056] The negative pressure hole 409 is located on the side wall of the drying chamber 402 and on the lower side of the rotating member 403. By connecting to the vacuum pump 6 and other equipment, a negative pressure environment can be created in the drying chamber 402. In this negative pressure environment, the boiling point of the water in the material is reduced, making it easier to evaporate. For the mud undergoing sedimentation separation and the mud residue after sedimentation, the negative pressure environment accelerates the evaporation process of the water therein, which not only helps to improve the drying degree of the subsequent mud residue and facilitates the subsequent treatment and disposal of the mud residue, but also can further reduce the water content in the separated solution, increase the concentration of the solution, and provide convenience for the recycling or further treatment of the solution.

[0057] Furthermore, the bottom of the rotating member 403 is a sieve plate with sieve holes, which are used to filter the solution in the solid-liquid separation chamber 410. The rotating member 403 and the inner wall of the drying chamber 402 form an evaporation groove 411. The evaporation groove 411 is arranged in the drying chamber 402 and is located below the rotating member 403. The evaporation groove 411 is interconnected with the negative pressure hole 409.

[0058] In this embodiment, the bottom of the rotating member 403 is a sieve plate with sieve holes. This design realizes the filtration of the solution in the solid-liquid separation chamber 410. When the solution in the solid-liquid separation chamber 410 passes through the sieve plate at the bottom of the rotating member 403, the solid phase particles therein are intercepted by the sieve holes, and the solution enters the evaporation tank 411 below for evaporation. The tank wall of the evaporation tank 411 is provided with a heating element for heating. The rotating member 403 and the inner wall of the drying chamber 402 form an evaporation groove 411, and the evaporation groove 411 is interconnected with the negative pressure hole 409. When the drying chamber 402 is in a negative pressure state, the solution filtered through the sieve plate will flow into the evaporation groove 411. Due to the negative pressure environment and the relatively large evaporation area of ​​the evaporation groove 411, the water in the solution can evaporate more quickly. This not only accelerates the removal of water and improves the efficiency of the entire drying process, but also combines with the previous solid-liquid separation and filtration process to form a complete system for efficiently separating water from mud and purifying the solution, further improving the low-temperature dryer 4's ability to handle liquid components in abandoned drilling materials.

[0059] Furthermore, it also includes a partition 13, which is arranged in the evaporation tank 411. The partition 13 has a connecting hole 1301. The partition 13 divides the evaporation tank 411 into a concentration chamber 412 and an evaporation chamber 413. The connecting hole 1301 is used to connect the concentration chamber 412 with the evaporation chamber 413. The pupil valve 14 is arranged on the connecting hole 1301. The concentration chamber 412 and the evaporation chamber 413 each have a negative pressure hole 409. There are two one-way valves 15, which are respectively arranged on a negative pressure hole 409. The bottom of the evaporation chamber 413 is a flap 16, which is rotatably arranged on the casing 401 and forms a drying chamber 402 with the casing 401. The flap 16 is used to discharge the residue in the evaporation chamber 413 after rotation.

[0060] In this embodiment, the partition 13 divides the evaporation tank 411 into a concentration chamber 412 and an evaporation chamber 413, and the connection between the two chambers is controlled by the pupil valve 14 set on the connecting hole 1301. This design can accurately adjust the flow of the solution between the concentration chamber 412 and the evaporation chamber 413. In the concentration chamber 412, the solution is initially evaporated under a negative pressure environment, and the concentration gradually increases. When a certain concentration is reached, the concentrated solution is allowed to flow into the evaporation chamber 413 for further evaporation by controlling the opening of the pupil valve 14. This process can flexibly adjust the concentration and evaporation degree of the solution according to actual processing needs, improve the accuracy and controllability of liquid processing in abandoned drilling materials, and ensure the stability and consistency of the processing effect.

[0061] Both the concentration chamber 412 and the evaporation chamber 413 are provided with negative pressure holes 409, and the airflow is controlled by a one-way valve 15. This design enables the two chambers to work independently under a negative pressure environment, while ensuring the reasonable flow of airflow. After the solution is initially evaporated in the concentration chamber 412, it enters the evaporation chamber 413 for deep evaporation, making full use of the characteristic that water is easy to evaporate under a negative pressure environment, thereby improving the overall evaporation efficiency. At the same time, by reasonably controlling the flow and evaporation process of the solution between the two chambers, unnecessary energy consumption is avoided, energy utilization is improved, and the cost of processing abandoned drilling materials is reduced.

[0062] A flap 16 is provided at the bottom of the evaporation chamber 413, which can be used to discharge the residue in the evaporation chamber 413 after rotation. This design allows the residual solid matter to be discharged from the equipment conveniently and quickly after the evaporation process is completed. Compared with the traditional cleaning method, the design of the flap 16 greatly reduces the difficulty and time of cleaning, and improves the maintenance efficiency of the equipment. The maintenance personnel only need to open the flap 16 to clean out the residue, which reduces the risk of equipment failure caused by untimely or difficult residue cleaning, prolongs the service life of the equipment, and ensures that the low-temperature dryer 4 can operate continuously and stably.

[0063] Furthermore, the condenser 5 includes a condensation shell 501 , the condensation shell 501 has a condensation chamber 502 , a condensation plate 503 is obliquely arranged in the condensation chamber 502 , the condensation plate 503 has a guide groove 504 and an air guide hole 505 , a liquid collector 506 is arranged in the condensation chamber 502 , and the guide groove 504 leads to the liquid collector 506 .

[0064] In this embodiment, the condensation plate 503 is tilted in the condensation chamber 502, which increases the contact area and contact time between the steam and the condensation plate 503. When the gas containing water vapor enters the condensation chamber 502, it fully contacts the tilted condensation plate 503 during the rising process, and the water vapor is quickly liquefied into water droplets when it is cooled. The tilted design allows the condensed water droplets to slide naturally under the action of gravity, avoiding the accumulation of water droplets on the condensation plate 503 and affecting the subsequent condensation effect, thereby improving the overall condensation efficiency, and being able to convert water vapor into liquid water more quickly, meeting the needs of water recovery and drying in the process of processing abandoned drilling materials.

[0065] The guide grooves 504 and air guide holes 505 on the condensation plate 503 further optimize the condensation process. The air guide holes 505 evenly guide the gas to various parts of the condensation plate 503, preventing the gas from concentrating in a certain area, and ensuring the full contact between the steam and the condensation plate 503. At the same time, the guide grooves 504 provide a special channel for the condensed water droplets, so that the water droplets can quickly flow along the guide grooves 504 to the liquid collector 506, avoiding the water droplets from flowing randomly on the condensation plate 503, reducing the possibility of the water droplets re-vaporizing, and further improving the condensation effect and water collection efficiency.

[0066] The liquid collector 506 is arranged in the condensation chamber 502, and the guide groove 504 leads to the liquid collector 506. This design ensures that the condensed water can be accurately and efficiently collected in the liquid collector 506. The coordinated work of the condensation plate 503 and the liquid collector 506 helps to better achieve gas-liquid separation. The inclined condensation plate 503 allows the condensed water to slide down quickly, while the uncondensed gas continues to rise or be discharged in the condensation chamber 502. The guide groove 504 guides the water droplets to the liquid collector 506, further avoiding the re-mixing of gas and liquid, and ensuring the thoroughness of gas-liquid separation.

[0067] The structural design of the condenser 5 is relatively simple and clear, which is convenient for maintenance personnel to clean and maintain. The positions of the inclined condensation plate 503 and the liquid collector 506 are clear. If dirt or impurities appear on the condensation plate 503 and affect the condensation effect, the maintenance personnel can easily clean it. Similarly, the liquid collector 506 is also easy to inspect and clean, reducing the problem of increased maintenance difficulty caused by the complex structure of the equipment. This design that is easy to maintain reduces the downtime of the equipment, reduces maintenance costs, and improves the availability and reliability of the equipment.

[0068] Furthermore, the liquid collector 506 is located at the bottom of the condensation chamber 502 , and further includes a U-shaped tube 17 . The liquid collector 506 leads to the U-shaped tube 17 , and the U-shaped tube 17 leads to the liquid collecting pump 18 .

[0069] In this embodiment, the liquid collector 506 leads to the U-shaped tube 17, and the unique shape of the U-shaped tube 17 plays an important buffering and backflow prevention function. When the liquid flows from the liquid collector 506 into the U-shaped tube 17, a certain amount of liquid will remain in the U-shaped tube 17 to form a liquid seal. On the one hand, this liquid seal can buffer the impact force of the liquid during the flow process, prevent the liquid from impacting the subsequent liquid collecting pump 18 due to reasons such as excessive flow rate, protect the liquid collecting pump 18, and extend its service life; on the other hand, the liquid seal can effectively prevent the liquid from backflowing when pressure fluctuations occur during the operation of the equipment, and ensure that the liquid can only flow in a predetermined direction, that is, from the liquid collector 506 through the U-shaped tube 17 to the liquid collecting pump 18, thereby ensuring the unidirectionality and stability of the liquid delivery path, making the entire liquid collection and delivery system more reliable. The buffering and stabilizing effect of the U-tube 17 on the liquid makes the liquid flow and pressure entering the liquid collecting pump 18 more uniform and stable, avoiding abnormal conditions such as idling and overloading of the liquid collecting pump 18 due to unstable liquid inlet, ensuring that the liquid collecting pump 18 can operate stably under suitable working conditions, maximizing its pumping capacity, improving the working efficiency of the liquid collecting pump 18, and also reducing the wear of the liquid collecting pump 18 caused by abnormal working conditions, extending its service life, and reducing the maintenance cost of the equipment. Due to the presence of liquid seals in the U-tube 17, some impurities that may flow with the liquid will settle at the bottom of the U-tube 17 under the action of gravity, and are not easy to enter the liquid collecting pump 18 with the liquid, thereby reducing the possibility of impurities accumulating and clogging inside the liquid collecting pump 18, ensuring the normal operation of the liquid collecting pump 18, further improving the reliability of the entire liquid collection and transportation system, reducing the downtime caused by equipment failure, and helping the waste drilling material processing device to work continuously and stably.

[0070] Furthermore, it also includes a second baffle 19, which is arranged in the drying chamber 402 and located on the side of the mud outlet 408. The second baffle 19 is used to block part of the sieve holes at the bottom of the rotating part 403 close to the mud outlet 408, and is used to block all the sieve holes of at least one isolation chamber 404.

[0071] In this embodiment, the bottom sieve holes of the connected isolation chamber 404 effectively prevent the negative pressure in the drying chamber 402 from leaking through these sieve holes. When the mud is discharged from the mud outlet 408, if there is no obstruction by the second baffle 19, the outside air can easily enter the drying chamber 402 through the sieve holes, destroying the stability of the negative pressure environment. The existence of the second baffle 19 is like a barrier, blocking the channel that may cause negative pressure leakage, ensuring that the drying chamber 402 always maintains a stable negative pressure state, providing continuous and effective environmental conditions for the rapid evaporation of water in the material, thereby improving the efficiency and effect of the entire drying process.

[0072] Maintaining a uniform and stable negative pressure environment throughout the drying chamber 402 is essential for the normal operation of the equipment. By blocking the bottom sieve holes of a specific isolation chamber 404, the second baffle 19 helps to ensure that the negative pressure level in each area remains consistent. If the negative pressure fluctuates or is uneven, it may cause the material to be dried inconsistently in different areas, affecting the uniformity of the treatment effect. The precise blocking effect of the second baffle 19 allows the negative pressure environment to be evenly distributed in the drying chamber 402, ensuring that each batch of waste drilling materials is dried under the same conditions, improving the stability and reliability of the treatment results.

[0073] Furthermore, the dosing member 3 includes a flocculation tube 301 , which leads to the mixer 2 and is used to introduce flocculants into the mixer 2 , and an auxiliary coagulation tube 302 leads to the flocculation tube 301 and is used to introduce auxiliary coagulants into the flocculation tube 301 and preliminarily mix the auxiliary coagulants with the flocculants.

[0074] In this embodiment, in the treatment of waste drilling materials, the synergistic effect of flocculants and coagulants can significantly improve the solid-liquid separation effect. The coagulant tube 302 passes the coagulant into the flocculation tube 301, so that the two begin to mix preliminarily before entering the mixer 2. The coagulant can change the surface properties of the particles in the mud, creating better working conditions for the flocculant, thereby promoting the flocculant to combine with the suspended particles in the mud faster and more effectively to form larger and more compact flocs.

[0075] This premixing in the flocculation tube 301 ensures that the reagents entering the mixer 2 are in the best reaction state, greatly improving the reaction efficiency of the reagents with the waste drilling mud in the mixer 2. Compared with adding the two reagents directly to the mixer 2, mixing them in the flocculation tube 301 first can make the reagents work faster in the mixer 2, reduce the reaction time, and improve the speed of the entire treatment process.

[0076] After the flocculants and coagulants are preliminarily mixed in the flocculation tube 301, they enter the mixer 2 in the form of a relatively uniform mixed liquid. In the mixer 2, since the reagents have been preliminarily mixed, they can be more evenly dispersed in the waste drilling mud. This ensures that every part of the mud can be exposed to the appropriate proportion of flocculants and coagulants, avoiding the situation where the flocculation effect in some areas is poor due to uneven distribution of reagents.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
