Abstract
Description
Technical Field
[0001] The embodiments of this disclosure relate to the field of centrifuge technology, and more specifically, to a fully hydraulically driven centrifuge. Background Technology
[0002] In geological or mineral exploration, core drilling is commonly used. During geological drilling, clean water or bentonite-based drilling fluid is typically used. However, with increasingly stringent environmental regulations, traditional mud pit settling methods are no longer sufficient for geological drilling mud treatment. Centrifuge systems are now widely used to treat drilling mud, prepare drilling mud, recover drilling fluid, reduce drilling rig waste, and meet environmental requirements.
[0003] Most existing centrifuge systems are integrated and electrically driven. In some mountainous areas and remote wilderness locations with steep terrain, on the one hand, it is difficult for transport vehicles to transport the centrifuge system to the designated location, and the centrifuge system is too heavy to be lifted by helicopter; on the other hand, the use of electric drive is relatively limited, and an additional generator is required.
[0004] Therefore, existing centrifuge systems need to be improved to solve the above problems. Summary of the Invention
[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a fully hydraulically driven centrifuge to solve the problems mentioned in the background art, such as the inconvenience of transporting and the limitation of drive in mountainous and other locations with existing centrifuge systems.

[0008] According to one aspect, at least one embodiment of the present disclosure provides a fully hydraulically driven centrifuge, including a centrifuge module, a hydraulic power module, a slurry feed module and a frame, and also includes an engine module; The engine module is mounted on the frame.

The inlet control component is located in the inlet area, and the drain control component is located in the drain area. The bottom of the oil passage guide plate has several through holes for conveying hydraulic oil.
[0009] Based on the aforementioned scheme, the liquid inlet control assembly includes a liquid inlet control cylinder, a liquid delivery pipe, and a liquid inlet opening and closing part; The inlet control cylinder is connected and installed inside the diesel tank. The inlet filter is located inside the inlet control cylinder. The first inlet pipe is connected and installed on the inlet control cylinder. The inlet opening and closing part is installed inside the inlet control cylinder and can cut off the hydraulic oil passing through the first inlet pipe.
[0010] As a preferred technical solution of this disclosure, the liquid inlet opening and closing part includes an opening and closing screw, a hexagonal adjusting block, an opening and closing cylinder, and an I-shaped opening and closing slider. The opening and closing screw passes through and is rotatably disposed at the end of the liquid inlet control cylinder away from the liquid inlet filter. An opening and closing ball nut assembly is threaded onto the opening and closing screw. The hexagonal adjusting block is disposed at the end of the opening and closing screw away from the liquid inlet filter. The opening and closing cylinder is sleeved on the opening and closing ball nut assembly. The I-shaped opening and closing slider is sealed and slidably disposed axially within the opening and closing cylinder. One end of the I-shaped opening and closing slider is connected to one end of the opening and closing cylinder.
[0011] As a preferred technical solution of this disclosure, the drain control assembly includes a drain impurity reduction cylinder, a drain bend, a drain valve, a drain control cylinder, a second inlet pipe, and a drain opening and closing part. The drain impurity reduction cylinder is disposed inside the diesel tank, and the drain filter is located inside the drain impurity reduction cylinder. One end of the drain bend is connected to the bottom of the drain impurity reduction cylinder, and the other end extends through to one side of the diesel tank. The drain valve is installed on the drain bend. The drain control cylinder is connected to the diesel tank. One end of the drain control cylinder is connected to a spiral drain pipe that allows hydraulic oil to be spiraled into the drain impurity reduction cylinder. The second inlet pipe is connected to the drain control cylinder. The drain opening and closing part is disposed inside the drain control cylinder and can cut off the hydraulic oil passing through the second inlet pipe. The structure of the drain opening and closing part is the same as the structure of the inlet opening and closing part.
[0012] To facilitate secondary fine filtration of the hydraulic oil and ensure its uniform and stable distribution within the diesel tank, a secondary filter box is detachably and sealed at the top of the diesel tank. One end of the infusion pipe is connected to the bottom of the secondary filter box, which is equipped with a scraper to prevent clogging.
[0013] Based on the aforementioned scheme, the slag scraping section includes a slag scraping motor and a slag scraping plate. The slag scraping motor is installed on the secondary filter box, and the output end of the slag scraping motor extends into the secondary filter box. The slag scraping plate is disposed on the output end of the slag scraping motor and contacts the inner wall of the secondary filter box.
[0014] Based on the aforementioned scheme, a drain pipe is also provided on one side of the diesel tank, and a drain valve is installed on the drain pipe.
[0015] Furthermore, based on the aforementioned solution, a liquid level detection sensor is installed on one side of the diesel tank to detect the liquid level inside the diesel tank.
[0016] The beneficial effects of the embodiments disclosed herein are as follows: 1. The frame is equipped with an engine module, a hydraulic power module, a pulp inlet module, a centrifuge module, and a liquid collection module. All six modules can be independently installed and removed from the frame, forming a modular design. Each module is equipped with lifting lugs. Firstly, the lightweight modules can be individually transported to their designated locations by helicopter for installation, solving the problem of difficult transport in existing integrated centrifuge systems. Secondly, the fully hydraulic drive eliminates the need for electricity, using a diesel engine to power the hydraulic pump, which in turn drives the hydraulic motors of other modules, thus enabling their operation. This overcomes the power supply limitations of existing centrifuge systems using electric drives. 2. In this disclosure, by setting up an inlet control component and a drain control component, when filtering hydraulic oil, the hydraulic oil passes through the inlet filter for preliminary coarse filtration. After coarse filtration, the hydraulic oil enters the secondary filter cake box along the inlet control cylinder and the delivery pipe. It then undergoes secondary filtration through the secondary filter cake box. The hydraulic oil discharged from the secondary filter cake box is evenly distributed around the secondary filter cake cylinder to the upper part of the inlet area in the diesel tank. This allows the hydraulic oil to pass through the inlet area, oil passage, drain area, delivery pipe, drain control cylinder, spiral drain pipe, and drain impurity reduction cylinder, and be discharged from the drain filter. The drain filter then performs a third fine filtration of the hydraulic oil to improve the filtration accuracy of the hydraulic oil. 3. In this disclosure, when hydraulic oil enters the drain and impurity reduction cylinder through the spiral drain pipe, the hydraulic oil rotates around the drain filter as it passes through the drain filter. This not only improves the uniformity of the hydraulic oil passing through the drain filter, but also effectively prevents impurities in the hydraulic oil from adhering to the inner wall of the drain filter. Furthermore, the spiral flow of hydraulic oil, under the action of centrifugal force, can cause impurities to be spun into the bottom of the drain and impurity reduction cylinder. By opening the impurity discharge valve, the residual impurities can be removed, and the service life of the drain filter can be improved. 4. In this disclosure, by setting up an inlet control component and an outlet control component, when replacing the inlet filter and the outlet filter, it is not necessary to extract the hydraulic oil in the diesel tank. By rotating the hexagonal adjusting block, the I-shaped opening and closing slider moves towards the inlet filter or the outlet filter, so that the first or second inlet pipe is located in the middle of the I-shaped opening and closing slider. Then, the inlet filter or the outlet filter can be quickly disassembled, cleaned or replaced. Attached Figure Description

[0020] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0021] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0022] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0023] In this disclosure, unless otherwise expressly 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.

Therefore, they should not be construed as limitations on this disclosure.
[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0026] like Figure 1 As shown, this illustration depicts a fully hydraulically driven centrifuge according to one embodiment of this disclosure. The frame 001 houses an engine module 002, a hydraulic power module 003, a slurry inlet module 004, a centrifuge module 005, and a liquid collection module 006. All six modules can be independently mounted and dismounted from the frame 001, forming a modular design. Each module is equipped with lifting lugs. Firstly, the lightweight nature of each module allows for individual helicopter transport to a designated location for installation, solving the problem of difficult transport in existing integrated centrifuge systems. Secondly, the fully hydraulic drive eliminates the need for an electric power source, using a diesel engine to power the hydraulic pump, which in turn drives the hydraulic motors of other modules, thus enabling their operation. This overcomes the limitation of electric power supply in existing centrifuge systems.
[0027] like Figures 1-7As shown, a fully hydraulically driven centrifuge according to an embodiment of the present disclosure is illustrated, wherein an engine module 005 is mounted on a frame 004, and the engine module 005 includes a diesel tank 1, which is provided with a hydraulic purification mechanism capable of filtering diesel fuel.
[0028] As mentioned above, the drum is the core component of the centrifuge. It is usually cylindrical or conical and made of high-strength materials. The drum rotates at high speed under the drive of a hydraulic motor, so that the material can achieve solid-liquid separation or other separation processes under the action of centrifugal force. The inner surface of the drum may be equipped with various types of linings or filters to improve the separation effect and protect the inner wall of the drum.
[0029] The screw conveyor is located inside the drum and is installed coaxially with the drum. Its function is to transport the separated solid material from one end of the drum to the other end while the drum is rotating, so as to achieve continuous discharge. There is a certain difference between the speed of the screw conveyor and the speed of the drum. This difference is precisely controlled by a hydraulic differential to adapt to the separation and conveying needs of different materials.
[0030] The aforementioned frame 004 mainly consists of a body frame, a base, and vibration damping devices. The body frame and base are typically welded from high-strength steel and are used to support and fix the various components of the centrifuge, ensuring the stability and reliability of the equipment. Vibration damping devices are generally installed between the body and the base to reduce the vibration and noise generated during the centrifuge's high-speed rotation, preventing vibration from being transmitted to surrounding equipment and buildings. They also help protect the equipment's components and extend their service life.
[0031] It should be noted that the centrifuge module 001, hydraulic power module 002, pulp feeding module 003 and frame 004 mentioned above are all commonly used components in existing fully hydraulically driven centrifuges. Their specific structures and functions are not the main innovations of this application and will not be elaborated further here.
[0032] like Figure 2 As shown above, the hydraulic purification mechanism includes an inlet pipe 2, a drain pipe 4, and an oil circuit guide plate 6. The inlet pipe 2 is connected to one side of the diesel tank 1 through an inlet filter 3. The diesel tank 1 is equipped with an inlet control component that can assist in replacing the inlet filter 3. The drain pipe 4 is connected to one side of the diesel tank 1 through a drain filter 5. The diesel tank 1 is equipped with a drain control component that can assist in replacing the drain filter 5. The oil circuit guide plate 6 is sealed and connected inside the diesel tank 1. The oil circuit guide plate divides the diesel tank 1 into an inlet area and a drain area. The inlet control component is located in the inlet area, and the drain control component is located in the drain area. The bottom of the oil circuit guide plate 6 has several oil passage holes that can deliver hydraulic oil.
[0033] like Figure 5As shown, the inlet control assembly includes an inlet control cylinder 7, a delivery pipe 8, and an inlet opening / closing part. The inlet control cylinder 7 is connected to and installed inside the diesel tank 1. The inlet filter 3 is located inside the inlet control cylinder 7. The delivery pipe 8 is connected to and installed on the inlet control cylinder 7. The inlet opening / closing part is installed inside the inlet control cylinder 7 and can cut off the hydraulic oil passing through the delivery pipe 8. The inlet opening / closing part includes an opening / closing screw 9, a hexagonal adjusting block 11, an opening / closing cylinder 12, and an I-shaped opening / closing slide. Block 13, the opening and closing screw 9 passes through and is rotatably set at the end of the liquid inlet control cylinder 7 away from the liquid inlet filter 3, the opening and closing screw 9 is threadedly connected to the opening and closing ball nut assembly 10, the hexagonal adjusting block 11 is set at the end of the opening and closing screw 9 away from the liquid inlet filter 3, the opening and closing cylinder 12 is sleeved on the opening and closing ball nut assembly 10, the I-shaped opening and closing slider 13 is sealed and slidably set in the opening and closing cylinder 12, and one end of the I-shaped opening and closing slider 13 is connected to one end of the opening and closing cylinder 12.
[0034] Specifically, when cutting off the hydraulic oil flowing through the infusion tube 8, the hexagonal adjusting block 11 is rotated. The rotation of the hexagonal adjusting block 11 drives the opening and closing screw 9 to rotate. The rotation of the opening and closing screw 9 causes the opening and closing ball nut assembly 10 to move linearly. The movement of the opening and closing ball nut assembly 10 drives the opening and closing cylinder 12 to move. The movement of the opening and closing cylinder 12 can drive the I-shaped opening and closing slider 13 to slide.
[0035] like Figure 6 As shown, the drain control assembly includes a drain impurity reduction cylinder 14, a drain bend 15, a drain valve 16, a drain control cylinder 17, a second inlet pipe 19, and a drain opening and closing part. The drain impurity reduction cylinder 14 is installed inside the diesel tank 1, and the drain filter 5 is located inside the drain impurity reduction cylinder 14. One end of the drain bend 15 is connected to the bottom of the drain impurity reduction cylinder 14, and the other end extends to one side of the diesel tank 1. The drain valve 16 is installed on the drain bend 15. The drain control cylinder 17 is connected to the diesel tank 1, and one end of the drain control cylinder 17 is connected to a spiral drain pipe 184 that allows hydraulic oil to spiral into the drain impurity reduction cylinder 14. The second inlet pipe 19 is connected to the drain control cylinder 17, and the drain opening and closing part is installed inside the drain control cylinder 17, which can cut off the hydraulic oil passing through the second inlet pipe 19. The structure of the drain opening and closing part is the same as that of the inlet opening and closing part.
[0036] Specifically, by setting up inlet control components and outlet control components, when replacing inlet filter 3 and outlet filter 5, it is not necessary to extract the hydraulic oil in diesel tank 1. By rotating hexagonal adjusting block 11, the I-shaped opening and closing slider 13 is moved toward inlet filter 3 or outlet filter 5, so that infusion pipe 1 8 or infusion pipe 2 19 is located in the middle of I-shaped opening and closing slider 13. Then, inlet filter 3 or outlet filter 5 can be quickly disassembled, cleaned or replaced.
[0037] When hydraulic oil enters the drain and impurity reduction cylinder 14 through the spiral drain pipe 184, it rotates around the drain filter 5 as it passes through the drain filter 5. This not only improves the uniformity of the hydraulic oil passing through the drain filter 5, but also effectively prevents impurities in the hydraulic oil from adhering to the inner wall of the drain filter 5. Furthermore, the spiral flow of hydraulic oil, under the action of centrifugal force, can cause impurities to be spun into the bottom of the drain and impurity reduction cylinder 14. By opening the impurity discharge valve 16, the remaining impurities are removed, which also improves the service life of the drain filter 5.
[0038] It should be noted that, in order to facilitate secondary fine filtration of hydraulic oil and to ensure that the hydraulic oil is evenly and stably distributed into the diesel tank 1, a secondary filter box 20 is also sealed and detachably installed on the upper part of the diesel tank 1. One end of the infusion pipe 8 is connected to the bottom of the secondary filter box 20, and the secondary filter box 20 is equipped with a scraping part to prevent clogging.
[0039] The slag scraping section includes a slag scraping motor 21 and a slag scraping plate 22. The slag scraping motor 21 is installed on the secondary filter box 20, and the output end of the slag scraping motor 21 extends into the secondary filter box 20. The slag scraping plate 22 is set on the output end of the slag scraping motor 21 and contacts the inner wall of the secondary filter box 20.
[0040] Specifically, when the scraper motor 21 is started, the output end of the scraper motor 21 will drive the scraper plate 22 to rotate. Through the contact between the scraper plate 22 and the inner wall of the secondary filter box 20, the impurities attached to the inner wall of the secondary filter box 20 can be scraped off, preventing the filtration performance of the secondary filter box 20 from decreasing. When cleaning the secondary filter box 20, the secondary filter box 20 can be removed from the top of the diesel tank 1.
[0041] It is important to note that by setting up inlet control components and outlet control components, when filtering hydraulic oil, the hydraulic oil passes through inlet filter 3 for preliminary coarse filtration. After coarse filtration, the hydraulic oil enters the secondary filter cake box 20 along inlet control cylinder 7 and delivery pipe 1 8. It then undergoes secondary filtration through the secondary filter cake box 20. The hydraulic oil discharged from the secondary filter cake box 20 can be evenly distributed around the secondary filter cake cylinder to the upper part of the inlet area in the diesel tank 1. The hydraulic oil then passes through the inlet area, oil passage hole, outlet area, delivery pipe 2 19, outlet control cylinder 17, spiral outlet pipe 184, and outlet impurity reduction cylinder 14, and is discharged from the outlet filter 5. The outlet filter 5 performs a third fine filtration of the hydraulic oil to improve the filtration accuracy of the hydraulic oil.
[0042] In this process, after the hydraulic oil is dispersed into the inlet area through the secondary filter box 20, it can not only reduce the impact of the hydraulic oil in the inlet area and buffer the hydraulic oil, but also, as the hydraulic oil flows a long distance through the inlet area, oil passage hole and drain area, some impurities in the hydraulic oil will also settle at the bottom of the diesel tank 1, thus settling the impurities in the hydraulic oil.
[0043] As mentioned above, a drain pipe 23 is also provided on one side of the diesel tank 1. A drain valve 24 is installed on the drain pipe 23. By opening the drain valve 24, the hydraulic oil in the diesel tank 1 that has deteriorated due to long-term use can be replaced.
[0044] As mentioned above, a liquid level detection sensor 25 is installed on one side of the diesel tank 1 to detect the liquid level in the diesel tank 1.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
