Description

Technical Field

[0001] This invention belongs to the field of oak barrel processing technology, specifically relating to a device and method for removing old wood layers or ineffective carbonized layers from the inner wall of an oak barrel. Background Technology

[0002] Oak barrels, as a traditional wine storage container, primarily enhance wine quality through the aromatic substances in the oak wood of the barrel walls and the carbonized layer on the inner surface. Before filling with wine, the inner walls of the oak barrel are usually toasted to form an aromatic woody layer and an absorbent carbonized layer. During storage, the aroma of the woody layer is gradually released and infused into the wine, improving its flavor and mouthfeel. However, with prolonged use, the effective aromatic components in the woody layer are gradually depleted, the activity of the carbonized layer decreases, and impurities in the wine adhere to the inner wall of the barrel, hindering effective contact between the wine and the barrel wall. This further inhibits the dissolution of aromatic substances, making it difficult for older oak barrels to continue imparting the desired flavors to the wine. Therefore, to restore the excellent function of oak barrels, they need to be refurbished, which involves removing sediment from the inner walls of the barrel, removing the inactive carbonized layer, removing the old and tasteless wood, and re-toasting to form a new aromatic wood layer and an adsorbent carbonized layer, so that the oak barrel can be reused for the optimized storage of wine.

[0003] Traditional refurbishment processes typically involve disassembling the oak barrel staves one by one and planing each stave individually. However, disassembling the staves presents several problems: firstly, oak barrels are difficult to restore perfectly after disassembly, sometimes requiring the replacement of some staves; secondly, reassembly is a cumbersome process that necessitates re-cutting mortises, often resulting in a reduction in barrel volume or changes in external dimensions.

[0004] To address the problems associated with disassembling the aforementioned drum panels, some existing technologies have developed equipment that eliminates the need for disassembly. However, these devices are bulky (typically 3-4 meters tall) and heavy, occupying significant factory space and posing substantial challenges to export transportation, on-site handling, and installation. Furthermore, existing technologies employ metal scrapers to remove material from the inner wall of each drum panel. The continuous cutting of the hard wood layer by these scrapers leads to wear and tear, requiring replacement and increasing maintenance costs and operational downtime.

[0005] Therefore, there is a need for a device that can reduce the size and weight of the equipment while keeping the barrel intact (without removing the barrel boards), making it easy to transport and export. At the same time, it should be able to replace traditional metal knives, achieve automated operation, and efficiently remove old wood layers, sediments, and ineffective carbonized layers from the inner wall of oak barrels, thus ensuring the processing effect and overcoming the above-mentioned technical drawbacks. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an apparatus and method for automatically removing old wood layers or ineffective carbonized layers from the inner wall of oak barrels.

[0007] The specific technical solution of the present invention to solve the above-mentioned technical problems is as follows: One of the objectives of this invention is to provide a device for removing old wood layers or ineffective carbonized layers from the inner wall of oak barrels, including a base, on which a turntable assembly, a main lifting mechanism, a secondary lifting mechanism, a high-pressure nozzle, and a feed adjustment mechanism are provided; The turntable assembly includes an outer gear ring and a rotary drive motor for driving the outer gear ring to rotate. The outer gear ring is rotatably mounted on the base. The outer gear ring is used to support the oak barrel to be processed and drive the oak barrel to be processed to rotate. The base is provided with a gantry, the main lifting mechanism is detachably installed on the gantry, and the auxiliary lifting mechanism is set on the main lifting mechanism via an extension arm. The main lifting mechanism is used to control the overall lifting of the auxiliary lifting mechanism. The high-pressure nozzle is mounted on the auxiliary lifting mechanism, which drives the high-pressure nozzle to move up and down. The high-pressure nozzle is connected to an external high-pressure fluid supply device for removing old wood layers or ineffective carbonized layers from the inner wall of the oak barrel. The feed adjustment mechanism is used to adjust the distance between the high-pressure nozzle and the inner wall of the oak barrel. According to the curvature of the inner wall of the oak barrel and the different specifications and sizes of oak barrels (such as diameter), the distance between the high-pressure nozzle and the inner wall of the oak barrel can be flexibly adjusted to ensure that the high-pressure fluid always acts on the surface of the old wood layer or the failed carbonized layer with the best impact force. This not only ensures the cleaning effect, but also avoids the problems of insufficient flushing force due to excessive spacing, or damage to the oak barrel due to collision between the high-pressure nozzle and the inner wall of the oak barrel due to excessive spacing and excessive impact force. This improves the adaptability and versatility of the device to different models of oak barrels.

[0008] The present invention has the following advantages over the prior art: The equipment of this invention can remove the old wood layer or the failed carbonized layer on the inner wall of the oak barrel without disassembling the barrel board during operation, which not only ensures the original integrity of the barrel, but also avoids damage to the barrel caused by disassembly and assembly and subsequent complicated processes.

[0009] The main lifting mechanism of the present invention can be detachably installed on the gantry. After the main lifting mechanism is removed, the overall height of the machine can be significantly reduced in the transportation state, avoiding the increased export transportation difficulty caused by the large size of traditional non-disassembly barrel equipment, and significantly reducing transportation costs.

[0010] This invention enables fully automated high-pressure flushing removal of old wood layers or ineffective carbonized layers from the inner wall of oak barrels, thereby avoiding damage to the oak barrels and simplifying the process. Unlike traditional large-scale cutting tools, this invention uses high-pressure non-metallic fluid instead of traditional metal blades, effectively removing old wood layers or ineffective carbonized layers while significantly reducing the damage to the oak barrels during the process, avoiding increased maintenance costs and operational interruptions caused by blade wear.

[0011] This invention uses a feed adjustment mechanism to flexibly adjust the distance between the high-pressure nozzle and the inner wall of the oak barrel according to the curvature of the inner wall and the different specifications and sizes of the oak barrel (such as diameter). This ensures that the high-pressure fluid always acts on the surface of the old wood layer or the failed carbonized layer with the best impact force. This not only ensures the cleaning effect, but also avoids the problems of insufficient flushing force due to excessive spacing or damage to the oak barrel caused by collision between the high-pressure nozzle and the inner wall of the oak barrel due to excessive spacing or excessive impact force.

[0012] Furthermore, the auxiliary lifting mechanism includes an auxiliary drive motor and an auxiliary guide rod fixed on the extension arm. The output shaft of the auxiliary drive motor is driven by an auxiliary screw. The end of the auxiliary screw away from the auxiliary drive motor is rotatably mounted on a limiting plate. The end of the auxiliary guide rod away from the auxiliary drive motor passes through the limiting plate. It also includes an auxiliary slider, which is threadedly connected to the auxiliary screw. The auxiliary slider is also provided with a guide hole adapted to the auxiliary guide rod. The auxiliary guide rod passes through the guide hole. The high-pressure nozzle is disposed on the auxiliary slider.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: Driven by the auxiliary drive motor, the auxiliary screw rotates, and under the guidance of the auxiliary guide rod, the auxiliary slider moves smoothly along the axial direction of the auxiliary guide rod, thereby achieving precise displacement adjustment of the high-pressure nozzle in the axial direction of the oak barrel. This structural design allows the high-pressure nozzle to flexibly adjust its spray position according to the distribution of old wood layers or ineffective carbonized layers in different areas of the oak barrel's inner wall, ensuring a comprehensive and uniform flushing operation of the barrel's inner wall and avoiding cleaning dead zones. Simultaneously, the cooperation between the auxiliary guide rod and the guide hole on the auxiliary slider effectively ensures the stability and straightness of the auxiliary slider during movement, making the spray trajectory of the high-pressure nozzle more precise and controllable, further improving the efficiency and effectiveness of removing old wood layers or ineffective carbonized layers. Furthermore, the cooperation between the auxiliary lifting mechanism and the main lifting mechanism makes the overall structure of the device more compact. The main lifting mechanism is responsible for the large-stroke forward and backward movement of the auxiliary lifting mechanism, while the auxiliary lifting mechanism is responsible for the small-range lifting and lowering of the high-pressure nozzle itself, resulting in more flexible control and reducing the manufacturing difficulty and cost of a single large-stroke lifting mechanism. Compared with devices that use a single lifting structure, this invention can adapt to oak barrels of different sizes and heights. Even after the main lifting mechanism has undergone a large stroke adjustment, it can still achieve high-precision position adjustment within a small range, thus balancing adaptability and cleaning accuracy.

[0014] Furthermore, it also includes a clamping assembly, which is disposed on the base and symmetrically arranged on both sides of the outer gear ring. The clamping assembly includes a clamping cylinder, and the piston rod end of the clamping cylinder is provided with a horizontal end plate. Each end of the horizontal end plate is provided with a rolling element. The clamping assembly is used to clamp the oak barrel body.

[0015] The beneficial effects of this further solution are as follows: the clamping cylinder drives the piston rod to extend, causing the rolling elements on the horizontal end plate to make close contact with the outer wall of the barrel. A stable clamping force is applied radially to the barrel through symmetrically arranged clamping components on both sides. This effectively prevents the barrel from wobbling or shifting due to rotation as it rotates with the outer gear ring, ensuring that the barrel always maintains a coaxial rotational state. Simultaneously, the rolling friction between the rolling elements and the barrel provides reliable clamping without affecting the normal rotation of the barrel, while also preventing wear on the outer surface of the barrel and ensuring the structural integrity of the oak barrel.

[0016] Furthermore, the feed adjustment mechanism includes a feed adjustment motor fixedly mounted on the secondary slider and a ball screw assembly drivenly connected to the feed adjustment motor, and also includes a hinge arm. The secondary slider is provided with a horizontal slide rail, and the horizontal slide rail is provided with a horizontal slider. The high-pressure nozzle is disposed on the horizontal slider, and the horizontal slider is connected to the ball nut of the ball screw assembly via the hinge arm.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: The feed adjustment motor drives the ball screw pair, which converts the rotational motion into the linear motion of the ball nut. The ball nut, through the hinged arm, drives the horizontal slider to slide along the horizontal slide rail, thereby achieving horizontal feed adjustment of the high-pressure nozzle. This structural design can precisely control the horizontal displacement of the high-pressure nozzle, ensuring high-precision adjustment of the distance between it and the inner wall of the oak barrel, meeting the precise requirements for fluid impact force when removing old wood layers or ineffective carbonized layers of different depths. The hinged arm makes the movement of the horizontal slider more flexible and stable, effectively buffering the impact force during adjustment and avoiding adjustment jamming or component damage caused by rigid connections. Simultaneously, the cooperation between the horizontal slide rail and the horizontal slider provides stable guidance for the horizontal movement of the high-pressure nozzle, ensuring the accuracy of the nozzle position during adjustment and further improving the device's ability to precisely control the removal of old wood layers or ineffective carbonized layers.

[0018] Furthermore, the high-pressure nozzle is provided with a connecting bolt and a positioning bolt, and the horizontal slider is provided with a connecting hole and an arc-shaped groove. The high-pressure nozzle is rotatably mounted on the horizontal slider through the connecting bolt and the connecting hole. The positioning bolt passes through the arc-shaped groove, and the high-pressure nozzle locks its angle relative to the horizontal slider through the positioning bolt.

[0019] The advantages of adopting the above-mentioned further solution are as follows: The high-pressure nozzle can rotate flexibly around the axis of the connecting bolt through the cooperation of the connecting bolt and the connecting hole, thereby adjusting the spray angle. The arc-shaped groove provides the positioning bolt with a trajectory space for movement; once the high-pressure nozzle has rotated to the desired angle, tightening the positioning bolt will fix its angle. This design allows operators to precisely adjust the spray direction of the high-pressure fluid according to the inclination angle of the oak barrel's inner wall, the thickness distribution of the old wood layer or the failed carbonized layer, and the rinsing requirements, ensuring that the high-pressure fluid acts on the old wood layer or the failed carbonized layer at the optimal angle, improving removal efficiency. At the same time, the angle adjustment structure is simple, reliable, and easy to operate, enhancing the flexibility and adaptability of the device in practical applications.

[0020] Furthermore, the angle of the high-pressure nozzle is from -15° to 60°.

[0021] The beneficial effects of adopting the above-mentioned further solution are: this angle range can adapt to the inner wall curvature of most conventional oak barrels, and by adjusting the angle of the high-pressure nozzle, the impact effect is maximized, further improving the cleaning efficiency and effect, and adapting to different oak barrels.

[0022] Furthermore, the outer gear ring is provided with a support plate, which is used to support the oak barrel body, and the outer edge of the upper surface of the support plate is higher than the inner edge.

[0023] The beneficial effects of adopting the above-mentioned further solution are as follows: When the oak barrel is placed on the support plate, the inclined structure formed by the outer edge of the upper surface of the support plate being higher than the inner edge provides a certain positioning and limiting effect on the oak barrel. When the oak barrel is placed, its bottom edge will naturally contact the inclined part of the upper surface of the support plate, preventing the oak barrel from slipping off the outer toothed ring due to positional deviation during the initial placement or rotation start-up phase, thus improving the safety during operation. At the same time, this structure can also guide the wastewater, old wood layer, or decomposed carbonized layer debris generated during the flushing process to a certain extent to flow inward, avoiding the accumulation of fluid or solid particles in the contact area between the bottom of the barrel and the outer toothed ring, facilitating subsequent discharge and cleaning operations, and maintaining the cleanliness of the working environment of the device.

[0024] Furthermore, the base below the external gear ring is provided with a hollow structure for drainage. The base is provided with a positioning hole, and the end of the auxiliary guide rod away from the auxiliary drive motor is inserted into the positioning hole after it is lowered into position.

[0025] The beneficial effects of adopting the above-mentioned further solution are as follows: The hollow structure on the base below the external gear ring can promptly discharge the mixture of fluid and old wood layer or decomposed carbonized layer debris generated during the flushing process to the outside of the device, preventing it from accumulating on the base and causing corrosion to the internal components or affecting their normal operation. It also facilitates the subsequent centralized collection and treatment of the mixture of fluid and old wood layer or decomposed carbonized layer debris, keeping the bottom of the device dry and clean. Furthermore, the positioning holes on the base allow the secondary guide rod to be precisely inserted after it descends to its designated position, providing stable support and positioning. This effectively prevents the secondary lifting mechanism from shaking or shifting due to force on the cantilever end of the secondary guide rod when driving the high-pressure nozzle during lifting operations. This further ensures the stability and positional accuracy of the high-pressure nozzle during axial movement, guaranteeing the accuracy and reliability of the flushing operation.

[0026] The second objective of this invention is to provide a method for removing old wood layers or ineffective carbonized layers from the inner wall of an oak barrel. The method uses the device described above for removing old wood layers or ineffective carbonized layers from the inner wall of an oak barrel, and sprays fluid onto the surface to be cleaned on the inner wall of the oak barrel to remove old wood layers, sediment, or ineffective carbonized layers from inside the barrel.

[0027] Furthermore, the method specifically includes the following steps: S1. Remove the end plates from the oak barrel to be refurbished to obtain the oak barrel body to be processed, and place it on the support plate of the turntable assembly. S2. Start the clamping assembly to extend the piston rod driven by the clamping cylinder, which will move the horizontal end plate closer to the oak barrel until the rolling elements at both ends of the horizontal end plate abut against the outer wall of the oak barrel, thus centering the oak barrel. S3. Operate the main lifting mechanism to drive the auxiliary lifting mechanism and extension arm to descend, so that the end of the auxiliary guide rod of the auxiliary lifting mechanism is inserted into the positioning hole on the base to achieve positioning of the auxiliary lifting mechanism. S4. Start the auxiliary drive motor of the auxiliary lifting mechanism to drive the auxiliary screw to rotate, so that the auxiliary slider moves up and down along the auxiliary guide rod, thereby driving the high-pressure nozzle to rise and fall, positioning it to the initial position where flushing needs to begin. S5. Start the rotary drive motor, which drives the external gear ring to rotate on the base through gear transmission, thereby driving the support plate and the oak barrel it supports to rotate evenly around its own axis. S6. High-pressure fluid is ejected at high speed from the high-pressure nozzle and impacts the inner wall of the rotating oak barrel. At the same time, the auxiliary lifting mechanism continuously drives the high-pressure nozzle to slowly rise and fall. Combined with the rotation of the oak barrel, the high-pressure fluid can spirally flush the entire inner wall of the oak barrel. The debris and fluid flushed off are discharged in time through the hollow structure on the base. The pressure range of the high-pressure fluid is 30 MPa to 80 MPa; S7. By controlling the main lifting mechanism to fine-tune the overall height of the auxiliary lifting mechanism, or by repeatedly operating the auxiliary lifting mechanism to raise and lower it, the high-pressure nozzles can repeatedly flush the inner wall of the oak barrel to ensure that the old wood layer or the ineffective carbonized layer is completely removed.

[0028] The beneficial effects of this invention are as follows: This invention uses a fluid jet method to remove old wood layers or ineffective carbonized layers from the inner wall of oak barrels, achieving non-contact removal and avoiding physical damage such as scratches and excessive cutting caused by traditional mechanical removal. This maximizes the protection of the oak barrel's structural integrity and the natural texture of its inner wall. The liquid jet utilizes the impact force of water to soften and peel off the old wood layers or ineffective carbonized layers. This method is flexible in operation; the fluid type, pressure parameters, and jet angle can be selected according to the condition of the old wood layers or ineffective carbonized layers, achieving targeted removal and effectively removing old wood layers. Furthermore, the resulting mixture is easy to collect and treat, meeting environmental protection requirements and improving both efficiency and quality. Attached Figure Description

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] In this embodiment of the invention, recycled old oak barrels are processed. After removing the end plates of the oak barrels, the oak barrel body 1 to be processed can be obtained.

[0033] Example 1 like Figures 1 to 8 As shown, an apparatus for removing old wood layers or ineffective carbonized layers from the inner wall of an oak barrel includes a base 2, on which a turntable assembly 3, a main lifting mechanism 4, a secondary lifting mechanism 5, a high-pressure nozzle 6, and a feed adjustment mechanism 7 are provided. The turntable assembly 3 includes an external gear ring 301 and a rotary drive motor 302 and a reducer 303 for driving the external gear ring 301 to rotate. The external gear ring 301 is rotatably mounted on the base 2. A support plate 304 is provided on the external gear ring 301. The support plate 304 is used to support the oak barrel 1 to be processed and drive it to rotate along its own axis. A through hole is provided in the middle of the support plate 304. The outer edge of the upper surface of the support plate 304 is higher than the inner edge (i.e., the edge of the through hole), so that the support plate 304 forms an inward inclined angle to facilitate fluid flow from the through hole. The system has multiple guide holes, and a perforated structure 201 is provided on the base 2 below the outer gear ring 301. This perforated structure 201 is used to discharge the mixture of fluid and old wood layer or detritus carbonized layer debris or powder after flushing the inner wall of the oak barrel 1. A guide ring 11 is also provided at the bottom of the base 2 to guide the mixture flowing down from the perforated structure 201, preventing the mixture from randomly flowing across and polluting the surrounding environment. A water collection tray 12 and a filter device (not shown in the figure) are provided below the guide ring 11 to collect the mixture of fluid and old wood layer or detritus carbonized layer debris or powder, preventing direct discharge and environmental pollution. The filter device can separate solid particles from the fluid in the mixture, and the filtered fluid can be recycled or discharged in compliance with standards as needed, achieving resource conservation and environmental protection requirements. At the same time, the collected old wood layers or ineffective carbonized layer fragments are easy to process or recycle. Although the ability of the removed old wood layers or ineffective carbonized layers of oak barrels to improve the wine is limited, they still contain other aroma substances that can be reprocessed and put to good use elsewhere, thus improving the utilization rate of materials and conforming to the concept of green production.

[0034] The main lifting mechanism 4 is installed on the base 2. Specifically, the base 2 is provided with a gantry 203. The main lifting mechanism 4 is detachably installed on the gantry 203. The main lifting mechanism 4 is provided with a secondary lifting mechanism 5 via an extension arm 9. The overall lifting of the secondary lifting mechanism 5 is controlled by the main lifting mechanism 4.

[0035] Specifically, the main lifting mechanism 4 includes a connecting mounting plate 405, which is bolted to the gantry 203. The connecting mounting plate 405 is equipped with a main drive motor 401 and a main guide rod 402. A main screw 403 is driven onto the output shaft of the main drive motor 401, and a main slider 404 is threaded onto the main screw 403. The main guide rod 402 passes through the main slider 404 to guide it. The extension arm 9 is fixed to the main slider 404. Under normal operating conditions, the connecting mounting plate 405 is bolted to the gantry 203, allowing the auxiliary lifting mechanism 5 to reach its working height. When handling or loading for export, only the bolts need to be removed, and the connecting mounting plate 405, along with the main guide rod 402 and other mechanisms, can be lowered onto the base 2, reducing the height of the gantry 203 to meet loading height requirements. Upon arrival at the work site, it can be quickly raised and re-secured to restore its working state.

[0036] The auxiliary lifting mechanism 5 includes an auxiliary drive motor 501 and an auxiliary guide rod 503 fixed on the extension arm 9. An auxiliary screw 502 is drivenly connected to the output shaft of the auxiliary drive motor 501. The end of the auxiliary screw 502 away from the auxiliary drive motor 501 is rotatably connected to the limiting plate 504. The end of the auxiliary guide rod 503 away from the auxiliary drive motor 501 passes through the limiting plate 504. It also includes an auxiliary slider 505, which is threadedly connected to the auxiliary screw 502. The auxiliary slider 505 is provided with a guide hole that matches the auxiliary guide rod 503. The auxiliary guide rod 503 passes through the guide hole. The high-pressure nozzle 6 is installed on the auxiliary slider 505. The base 2 is provided with a positioning hole 202. The end of the auxiliary guide rod 503 away from the auxiliary drive motor 501 is inserted into the positioning hole 202 after it is lowered into position.

[0037] The system also includes a clamping assembly 8, which is mounted on the base 2 and symmetrically distributed on both sides of the outer gear ring 301. The clamping assembly 8 includes a clamping cylinder 801, with a horizontal end plate 802 at the piston rod end of the cylinder 801. Each end of the horizontal end plate 802 has a rolling element, which is a rubber wheel 803. The axle of the rubber wheel 803 is perpendicular to the ground. The clamping assembly 8 is used to support the oak barrel 1 from the side. The rubber wheel 803 has good elasticity and cushioning performance. When in contact with the outer wall of the oak barrel 1, it can adapt to the outer surface of the oak barrel 1 through its own deformation, thereby providing a more stable clamping force. The rubber material has a high coefficient of friction, which can effectively prevent relative sliding between the oak barrel 1 and the rolling element during clamping, further improving the reliability of clamping. At the same time, the soft texture of the rubber avoids scratches or compression damage to the oak barrel 1, better protecting the appearance quality of the oak barrel 1. The rubber wheel 803's axle is perpendicular to the ground, so that the rolling direction of the rubber wheel 803 is consistent with the rotation direction of the oak barrel 1, that is, it rolls along the circumference of the oak barrel 1. This ensures that the rolling element can smoothly follow the rotation when the oak barrel 1 rotates, minimizing the resistance to the rotation of the oak barrel 1 and ensuring the stability of the oak barrel 1's rotation process.

[0038] The high-pressure nozzle 6 is mounted on the auxiliary lifting mechanism 5, which is used to drive the high-pressure nozzle 6 to perform lifting operations.

[0039] The feed adjustment mechanism 7 is used to adjust the distance between the high-pressure nozzle 6 and the inner wall of the oak barrel 1. Specifically, the feed adjustment mechanism 7 includes a feed adjustment motor 701 fixed on the auxiliary slider 505, a ball screw pair connected to the feed adjustment motor 701, and a hinge arm 702. The auxiliary slider 505 is provided with a horizontal slide rail 703, and two horizontal sliders 704 are symmetrically arranged on the horizontal slide rail 703. Two high-pressure nozzles 6 are symmetrically arranged, so that the high-pressure fluid can simultaneously perform flushing operations from opposite sides of the inner wall of the oak barrel 1, forming a symmetrical fluid impact force. This avoids the barrel from shaking or shifting due to uneven force on one side caused by excessive flushing force from a single nozzle, ensuring the stability of the oak barrel 1 during rotation. At the same time, the arrangement of nozzles on both sides also improves flushing efficiency to a certain extent and shortens the overall operation time. The two high-pressure nozzles 6 are respectively installed on the two horizontal sliders 704, and the horizontal sliders 704 are connected to the ball nuts 705 of the ball screw pair through the hinge arm 702. The feed adjustment mechanism 7 is used to adjust the distance between the high-pressure nozzle 6 and the inner wall of the oak barrel.

[0040] The high-pressure nozzle 6 is equipped with a connecting bolt 601 and a positioning bolt 602. The horizontal slider 704 is equipped with a connecting hole and an arc-shaped groove 706. The high-pressure nozzle 6 is rotatably mounted on the horizontal slider 704 through the connecting bolt 601 and the connecting hole. The positioning bolt 602 passes through the arc-shaped groove 706, and the high-pressure nozzle 6 is locked at its angle relative to the horizontal slider 704 by the positioning bolt 602, thereby adjusting the angle of the fluid sprayed from the high-pressure nozzle 6 to effectively remove the old wood layer or the failed carbonized layer. The high-pressure nozzle 6 is connected to an external high-pressure fluid supply device for spraying high-pressure fluid onto the inner wall of the oak barrel to remove the old wood layer or the failed carbonized layer from the inner wall of the oak barrel. The high-pressure fluid is selected from water or wine. In this embodiment, the angle adjustment range of the high-pressure nozzle 6 is -15° to 60° (upward tilt from the horizontal direction is negative, downward tilt is positive). In this embodiment, the angle of the high-pressure nozzle 6 is preferably 25°. The high-pressure fluid is high-pressure water, and the pressure range of the high-pressure water is 30 MPa to 80 MPa. In this embodiment, the pressure of the high-pressure water is preferably 50 MPa.

[0041] It also includes protective plates 10, which are installed around the base 2. During operation, the protective plates 10 effectively block the fluid generated by the high-pressure flushing operation, as well as debris from old wood layers or deteriorated carbonized layers, preventing splashing and diffusion to the outside of the device, thus avoiding pollution of the surrounding working environment. Simultaneously, the protective plates 10 also form a safety barrier, preventing operators from accidentally contacting the rotating oak barrel 1 or other moving parts, reducing the risk of accidents and providing a safer working environment for operators. Furthermore, the protective plates 10 can reduce the contamination of the internal precision components by external environmental factors (such as dust and debris), helping to maintain the device's good operating condition and extend its service life.

[0042] Example 2 A method for removing old wood layers or ineffective carbonized layers from the inner wall of an oak barrel involves spraying a fluid onto the surface to be cleaned inside the oak barrel to remove old wood layers, sediment, or ineffective carbonized layers.

[0043] The fluid is selected from either water or alcohol. The pressure range of the fluid is 30 MPa to 80 MPa; in this embodiment, the fluid is high-pressure water with a pressure of 50 MPa.

[0044] In actual operation, before starting, the main lifting mechanism 4 will drive the auxiliary lifting mechanism 5 and the extension arm 9 to rise to the highest point as a whole, so as not to hinder the loading and unloading of the oak barrel 1.

[0045] The method described in this embodiment uses the apparatus for removing old wood layers or ineffective carbonized layers from the inner wall of oak barrels as described in Embodiment 1, and specifically includes the following steps: S1. Remove the end plates from the oak barrel to be refurbished to obtain the oak barrel body 1 to be processed. Open a protective plate 10 and place the oak barrel body 1 on the support plate 304 of the outer toothed ring 301 of the turntable assembly 3. The design of the outer edge of the upper surface of the support plate 304 being higher than the inner edge can play a basic limiting role for the oak barrel body 1.

[0046] S2. Start the clamping assembly 8. The clamping cylinders 801 on both sides drive the piston rod to extend, causing the horizontal end plate 802 to move closer to the oak barrel 1 until the rubber wheels 803 at both ends of the horizontal end plate 802 abut against the outer wall of the oak barrel 1. Since the two clamping assemblies 8 are symmetrically arranged, the straight line of their axis of symmetry coincides with the rotation axis of the oak barrel 1, so it can play the role of centering the oak barrel 1. At the same time, the rubber wheel 803 has a certain elasticity, which can provide a stable clamping force to prevent the oak barrel 1 from shaking when rotating at high speed, and also prevent hard damage to the outer wall of the barrel. Its wheel axle design perpendicular to the ground allows the oak barrel 1 to rotate smoothly while being clamped.

[0047] S3. Operate the main lifting mechanism 4 to drive the auxiliary lifting mechanism 5 and the extension arm 9 to descend as a whole. The end of the auxiliary guide rod 503 of the auxiliary lifting mechanism 5 is inserted into the positioning hole 202 on the base 2 to achieve a firm positioning of the auxiliary lifting mechanism 5.

[0048] S4. Start the auxiliary drive motor 501 of the auxiliary lifting mechanism 5 to adjust the high-pressure nozzle 6 to the working height range inside the oak barrel 1. Specifically, the auxiliary drive motor 501 drives the auxiliary screw 502 to rotate. Since the auxiliary slider 505 is threadedly connected to the auxiliary screw 502 and guided by the auxiliary guide rod 503, the auxiliary slider 505 moves stably up and down along the auxiliary guide rod 503, thereby driving the high-pressure nozzle 6 to rise and fall, and accurately positioning it to the initial position where rinsing needs to begin.

[0049] Furthermore, the distance between the high-pressure nozzle 6 and the inner wall of the oak barrel can be further optimized through the feed adjustment mechanism 7. The feed adjustment motor 701 drives the ball screw pair to work, and the ball nut 705 of the ball screw pair drives the horizontal slider 704 to slide along the horizontal slide rail 703 through the hinge arm 702. The horizontal slider 704 carries the high-pressure nozzle 6 closer to or further away from the barrel wall to adapt to oak barrels of different inner diameters or to the curvature of the inner wall of the oak barrel, ensuring that the high-pressure fluid can act on the old wood layer or the deteriorated carbonized layer with the best impact force. In addition, the high-pressure nozzle 6 is rotatably mounted on the horizontal slider 704 through the connecting bolt 601. Loosening the positioning bolt 602 allows the high-pressure nozzle 6 to be rotated around the connecting bolt 601 to adjust its spray angle, ensuring that the impact angle of the high-pressure fluid can act more effectively on the old wood layer or the deteriorated carbonized layer. After adjustment, the positioning bolt 602 is locked in the arc groove 706 to fix the current angle, achieving all-round, no-dead-angle flushing coverage of the inner wall of the oak barrel.

[0050] S5. The rotary drive motor 302 starts, driving the outer gear ring 301 to rotate on the base 2 via gear transmission. The outer gear ring 301 then drives the support plate 304 and the oak barrel 1 it supports to rotate uniformly around its own axis. At the same time, an external high-pressure water source supplies water to the high-pressure nozzle 6 through a pipeline. The high-pressure fluid is ejected at high speed from the high-pressure nozzle 6, impacting the inner wall of the rotating oak barrel 1. During this process, the auxiliary lifting mechanism 5 continuously drives the high-pressure nozzle 6 to slowly rise and fall. Combined with the rotational motion of the oak barrel 1, this allows the high-pressure fluid to spirally and thoroughly flush the inner wall of the entire oak barrel 1.

[0051] S6. The high-speed water flow can quickly peel off and remove the old wood layer or the failed carbonized layer. The old wood layer or the failed carbonized layer debris and fluid washed off are discharged in time through the hollow structure 201 on the base 2 below the outer tooth ring 301, so as to avoid accumulation in the barrel and affect the flushing effect.

[0052] S7. For areas with deeper or more stubborn carbonization, the overall height of the auxiliary lifting mechanism 5 can be finely adjusted by controlling the main lifting mechanism 4, or the auxiliary lifting mechanism 5 can be repeatedly operated to allow the high-pressure nozzle 6 to flush the area multiple times, ensuring that the old wood layer or ineffective carbonized layer is completely removed. The entire process is automated, greatly reducing labor intensity and improving cleaning efficiency. High-pressure fluid flushing replaces the traditional method of scraping with metal blades. By setting the water pressure and adjusting the angle and distance of the high-pressure nozzle 6, the high-pressure fluid can effectively remove the old wood layer or ineffective carbonized layer while avoiding damage to the oak barrel. The entire cleaning process causes minimal damage to the oak barrel's wooden structure, effectively ensuring the quality and lifespan of the refurbished oak barrel.
