Description

Technical Field

[0001] This invention relates to the field of spinning oil recovery technology, and in particular to a spinning oil recovery device that improves coating quality and environmental friendliness. Background Technology

[0002] In the chemical fiber spinning process, spinning oil plays a crucial role. It forms a uniform lubricating film on the fiber surface, effectively reducing friction between the fiber and equipment, minimizing static electricity, and thus ensuring smooth spinning and improving fiber quality and spinnability. However, as spinning production continues, large amounts of waste gas and liquid containing spinning oil are constantly generated. Directly discharging this waste into the environment not only results in significant waste of spinning oil and increased production costs but also causes substantial harm to the ecological environment. The chemical components in spinning oil may pollute soil and water sources, affecting ecological balance and endangering human health. Therefore, the recycling and reuse of spinning oil has significant economic and environmental implications.

[0003] Currently, there are some spinning oil recovery devices on the market that improve coating quality and environmental friendliness, but these devices have many problems in practical applications and cannot meet the needs of modern spinning production for high efficiency, environmental protection and energy saving.

[0004] Existing spinning oil recovery devices designed to improve coating quality and environmental friendliness suffer from insufficient recovery of spinning oils due to design and technological limitations. For example, some devices employ simple filtration or sedimentation methods, which can only recover some larger oil particles. They fail to effectively separate and recover smaller oil particles and components dissolved in waste liquid. This results in a significant waste of resources as valuable spinning oils are still discharged with waste gas and waste liquid, reducing the economic benefits for enterprises. Furthermore, the inefficient recovery necessitates frequent replenishment of spinning oils, further increasing production costs.

[0005] In the process of recovering spinning oil, it is necessary to effectively separate the oil from other impurities in the waste gas and waste liquid. However, existing recovery devices have significant shortcomings in the separation stage. Some devices have unreasonable separation structures, making it impossible to achieve high-precision separation of oil and impurities. For example, in the gas-liquid separation process, oil droplets entrained in the waste gas cannot be fully separated, resulting in the recovered oil still containing a large number of impurities, affecting the quality and purity of the recovered oil. When low-quality recovered oil is reused, it may lead to problems such as decreased fiber quality and increased breakage rate during the spinning process, affecting production stability and product quality.

[0006] Existing spinning oil recovery devices designed to improve coating quality and environmental friendliness consume significant amounts of energy during operation. On one hand, some devices employ energy-intensive heating, cooling, and stirring equipment to achieve oil recovery and separation. For example, some recovery units require high-temperature heating of the waste liquid to promote oil separation, which not only consumes substantial amounts of thermal energy but also increases operating costs and maintenance complexity. On the other hand, the overall design of these devices is not energy-efficient and lacks effective energy recovery and reuse mechanisms. For instance, waste heat generated during oil recovery is not utilized effectively but is directly released into the environment, resulting in energy waste. These energy-intensive recovery devices not only increase production costs for enterprises but also fail to meet current environmental protection requirements for energy conservation and emission reduction.

[0007] Existing spinning oil recovery devices designed to improve coating quality and environmental friendliness suffer from insufficient equipment and control systems, making them prone to malfunctions. Since spinning production typically requires continuous operation, the stability of the recovery device is crucial. However, some recovery devices suffer from substandard component quality, leading to wear and damage, and frequent downtime for maintenance. For example, filter screens are prone to clogging and frequent replacement; pumps and valves are susceptible to leakage, affecting normal operation. Furthermore, the control systems are not intelligent enough to monitor and adjust parameters in real time, failing to issue timely alarms and take appropriate measures when abnormalities occur, further reducing equipment stability and reliability. Unstable equipment operation not only affects the recovery efficiency and quality of spinning oils but can also lead to the shutdown of the entire spinning production line, causing significant economic losses to enterprises.

[0008] Existing spinning oil recovery devices designed to improve coating quality and environmental friendliness suffer from numerous operational and maintenance inconveniences. Some devices have complex interfaces, requiring operators with advanced professional knowledge and skills, increasing operational difficulty and training costs. Furthermore, the devices have low levels of automation, necessitating manual operation for many tasks, which is not only inefficient but also prone to human error. In terms of maintenance, the devices' structural design is inadequate, making disassembly and installation of components difficult and significantly hindering daily maintenance. For example, the compact layout of internal piping and equipment in some recovery devices makes it difficult for maintenance personnel to access for inspection and cleaning, leading to extended maintenance cycles and increased maintenance costs.

[0025] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example

[0026] like Figures 1-7As shown, an embodiment of the present invention proposes a spinning oil recovery device for improving coating quality and environmental friendliness, comprising an oil storage tank 1. A shielding part 2 is installed on the top of the oil storage tank 1, and the shielding part 2 consists of a lower housing 21 and an upper housing 22. The lower housing 21 is fixedly installed on the surface of the oil storage tank 1 by bolts or other means, and the upper housing 22 is positioned above the lower housing 21; the two are detachably connected by snap-fits or other means. A through groove 23 is provided on one side of both the lower housing 21 and the upper housing 22. The size of the through groove 23 is designed according to the diameter of the spinning yarn, for the spinning yarn to pass through smoothly through the shielding part 2. The lower housing 21 and the upper housing 22 form a cavity, and a wiping part 3 is provided on the top of the oil storage tank 1, located within the cavity formed by the lower housing 21 and the upper housing 22. The wiping unit 3 includes a motor 31, a rotating rod 32, and a wiping cylinder 33. The motor 31 is mounted on the back of the oil storage tank 1, and the rotating rod 32 is mounted on the inner wall of the oil storage tank 1 and rotatably connected via bearings. The output end of the motor 31 is connected to the rotating rod 32, and the wiping cylinder 33 is mounted on the surface of the rotating rod 32. When the motor 31 operates, it drives the rotating rod 32 and the wiping cylinder 33 to rotate. As the wiping cylinder 33 rotates, it carries the oil stored in the oil storage tank 1 to the top of the wiping cylinder 33, thereby wiping the passing yarn and evenly coating the yarn surface with oil. The top of the wiping unit 3 is provided with a squeezing part 5, which is mounted on the upper housing 22. The squeezing part 5 is used to limit the yarn, ensuring that the yarn can closely contact the surface of the wiping cylinder 33 and guaranteeing the coating effect. The oil storage tank 1 is internally equipped with a limiting section 6, which includes a support plate 61, a mounting plate 65, and a support spring 64. The mounting plate 65 is installed on the inner bottom wall of the oil storage tank 1, and the support spring 64 is installed on top of the mounting plate 65. The support plate 61 is located inside the oil storage tank 1. When the oil content in the oil storage tank 1 decreases, the support spring 64 pushes the support plate 61 upward, thereby limiting the oil and keeping it at a certain height for easy oil collection by the wiping section 3. This spinning oil recovery device, which improves coating quality and environmental friendliness, uses a shielding section 2 to protect internal components, a wiping section 3 to apply oil to the spinning process, a squeezing section 5 to ensure coating effect, and a limiting section 6 to ensure a reasonable oil supply, thus completing the functions of spinning oil recovery and coating.

[0027] In this invention, the extrusion section 5 includes a limiting spring 51, a connecting plate 52, a pressure rod 53, and a pressure roller 54. The limiting spring 51 is installed on the top of the upper housing 22, the connecting plate 52 is installed on the top of the limiting spring 51, the pressure rod 53 is installed at the bottom of the connecting plate 52 and extends into the upper housing 22, and the pressure roller 54 is installed at the end of the pressure rod 53 and positioned above the wiping cylinder 33 of the wiping section 3. When the spinning yarn passes through, under the elastic force of the limiting spring 51, the connecting plate 52 drives the pressure rod 53 and the pressure roller 54 to move downwards, squeezing the spinning yarn to the wiping cylinder 33, making the spinning yarn in close contact with the surface of the wiping cylinder 33, thereby evenly coating the oil on the wiping cylinder 33 onto the spinning yarn surface. The oil recovery of the spinning yarn is ensured by the extrusion action of the extrusion section 5, which guarantees sufficient contact between the spinning yarn and the wiping cylinder 33, improving the uniformity and effect of the oil coating.

[0028] In this invention, the limiting unit 6 includes a support plate 61, a mounting plate 65, and a support spring 64. The mounting plate 65 is fixedly installed on the inner bottom wall of the oil storage tank 1 by welding or other means. The support spring 64 is installed on the top of the mounting plate 65, and the support plate 61 is horizontally positioned inside the oil storage tank 1. When oil is injected into the oil storage tank 1, the oil exerts pressure on the support plate 61, causing the support spring 64 to compress. As the oil is consumed, the oil content decreases, the pressure of the oil on the support plate 61 decreases, and the support spring 64 pushes the support plate 61 upward under the action of elasticity, thereby maintaining contact between the oil and the wiping part 3, achieving oil limiting, and ensuring that the wiping part 3 can continuously collect oil. The spinning oil recovery limiting unit 6 can automatically adjust the position of the support plate 61 according to the change in the oil quantity in the oil storage tank 1, ensuring a reasonable oil supply and enabling the device to work normally under different oil quantity conditions.

[0029] In this invention, the limiting part 6 further includes a limiting ring 63 installed on the inner wall of the oil storage tank 1 and a sealing ring 62 installed on the surface of the support plate 61. The sealing ring 62 is made of sealing material such as rubber and is fitted onto the surface of the support plate 61. When the support plate 61 moves up and down inside the oil storage tank 1, the sealing ring 62 can tightly fit against the inner wall of the oil storage tank 1, achieving a seal between the support plate 61 and the oil storage tank 1, preventing oil leakage. The limiting ring 63 is installed at a certain height on the inner wall of the oil storage tank 1. When the oil level is too low, when the support spring 64 pushes the support plate 61 upward, the limiting ring 63 can prevent the support plate 61 from continuing to rise, preventing the support plate 61 from directly contacting the wiping part 3, avoiding damage to the wiping part 3 or affecting its normal operation. The spinning oil recovery sealing ring 62 ensures the sealing of the oil storage tank 1 and reduces oil waste; the limiting ring 63 prevents the support plate 61 from rising excessively, protecting the wiping part 3 and improving the stability and reliability of the device.

[0030] In this invention, the wiping unit 3 includes a motor 31, a rotating rod 32, and a wiping cylinder 33. The motor 31 is fixedly mounted on the back of the oil storage tank 1 by bolts. The two ends of the rotating rod 32 are mounted on the inner wall of the oil storage tank 1 by bearings, achieving a rotatable connection. The output end of the motor 31 is connected to the rotating rod 32 by a coupling. The wiping cylinder 33 is made of oil-absorbing material such as sponge, and is sleeved on the surface of the rotating rod 32 and fixed by keys or other means. When the motor 31 starts, it drives the rotating rod 32 and the wiping cylinder 33 to rotate. During the rotation, the wiping cylinder 33 comes into contact with the oil in the oil storage tank 1 and absorbs the oil on its surface. When the spinning process passes over the wiping cylinder 33, the oil on the surface of the wiping cylinder 33 is applied to the spinning surface, achieving oil application for the spinning process. The spinning oil recovery wiping unit 3, driven by the motor 31 to rotate the wiping cylinder 33, can continuously and evenly apply oil to the spinning surface, meeting the oil requirements during the spinning production process.

[0031] In this invention, a scraper 4 is installed on the inner wall of the lower housing 21. The scraper 4 is used to clean the oil adhering to the wiping cylinder 33 when the wiping cylinder 33 rotates. When the wiping cylinder 33 rotates and comes into contact with the spinning process, some oil and impurities that have come into contact with the spinning process will adhere to its surface. The scraper 4 can promptly clean off these adhering substances, preventing the wiping cylinder 33 from carrying the oil that has come into contact with the spinning process into the oil storage tank 1, thus avoiding affecting the purity of the oil in the oil storage tank 1 and ensuring the quality of the oil agent applied to the spinning process subsequently. The spinning oil agent recovery scraper 4 effectively cleans the adhering substances on the surface of the wiping cylinder 33, keeps the oil in the oil storage tank 1 clean, and improves the quality and stability of the spinning oil agent application.

[0032] In this invention, the scraping section 4 includes an arc-shaped scraper 41, a connecting spring 43, and a telescopic rod 44. Both the connecting spring 43 and the telescopic rod 44 are installed on the inner wall of the lower housing 21, with the connecting spring 43 sleeved on the surface of the telescopic rod 44. The ends of both the connecting spring 43 and the telescopic rod 44 are connected to the arc-shaped scraper 41. The shape of the arc-shaped scraper 41 is adapted to the surface of the wiping cylinder 33, allowing it to fit tightly against the surface of the wiping cylinder 33. When the wiping cylinder 33 rotates, the arc-shaped scraper 41, under the action of the connecting spring 43 and the telescopic rod 44, maintains constant contact with the surface of the wiping cylinder 33, scraping off oil and impurities from the surface of the wiping cylinder 33. A drain hole 42 is provided through the top of the arc-shaped scraper 41, through which the scraped oil flows into the lower housing 21 for temporary storage, and can be further processed or recycled later. The spinning oil recovery scraping section 4 effectively cleans the surface of the wiping cylinder 33 through close contact between the arc-shaped scraper 41 and the wiping cylinder 33. The design of the leakage hole 42 allows the cleaned oil to be recycled, improving the utilization rate of resources.

[0033] In this invention, a shield 7 is installed on the inner wall of the lower housing 21, and one side of the shield 7 is connected to the oil storage tank 1 by welding or other means. A notch 71 is provided on the side of the shield 7, and a filter plate 8 is installed inside the notch 71. The filter plate 8 is made of filter materials such as filter screens and can filter the oil, removing impurities. An oil drain groove 11 is provided on the side of the oil storage tank 1 at the shield 7. The oil temporarily stored in the lower housing 21, after being filtered by the filter plate 8, flows into the oil storage tank 1 through the oil drain groove 11, realizing the recycling of oil, improving oil utilization, and reducing production costs. The combination of the spinning oil recovery shield 7 and the filter plate 8 achieves oil filtration and recycling, ensuring the purity of the oil in the oil storage tank 1, while reducing oil waste and improving the economy and environmental friendliness of the device.

[0034] In this invention, a drain pipe 24 is installed at the bottom of the lower housing 21, which is used to discharge filtered impurities. When the impurities filtered by the filter plate 8 accumulate to a certain level, they can be discharged from the device through the drain pipe 24. A plug 25 is inserted into the bottom of the drain pipe 24. The plug 25 is made of rubber or other materials and is used to seal the drain pipe 24 to prevent oil or impurities from leaking during normal operation. An oil injection pipe 26 is installed at the top of the upper housing 22. When the oil level in the oil tank 1 is insufficient, new oil can be injected into the oil tank 1 through the oil injection pipe 26 to ensure the normal operation of the device. The design of the spinning oil recovery drain pipe 24 and the plug 25 facilitates the cleaning of impurities and the sealing of the device. The oil injection pipe 26 ensures timely replenishment of oil, enabling the device to operate continuously and stably.

[0035] In this invention, a support plate 27 is installed at the top of the surface of the lower housing 21, and an mounting plate 28 is installed at the bottom of the surface of the upper housing 22, with the bottom of the mounting plate 28 contacting the support plate 27. A threaded post 271 is installed at the top of the support plate 27, extending through to the top of the mounting plate 28. A nut 281 is provided at the top of the mounting plate 28, and the nut 281 is threadedly connected to the threaded post 271. When it is necessary to disassemble the upper housing 22 and the lower housing 21, simply unscrew the nut 281 to remove the upper housing 22 from the lower housing 21, facilitating the inspection, cleaning, or replacement of internal components. During installation, align the mounting plate 28 of the upper housing 22 with the support plate 27 of the lower housing 21, ensuring the threaded post 271 passes through the mounting plate 28, and then screw on the nut 281 to complete the installation. The operation is convenient and quick. The spinning oil recovery system utilizes a combination of support plate 27, mounting plate 28, threaded post 271, and nut 281 to achieve a detachable connection between the upper housing 22 and the lower housing 21, which facilitates the maintenance and upkeep of the device and improves its ease of use and maintainability.

[0036] The working principle of this invention is as follows: The oil level in the oil tank 1 is checked. If the oil level is insufficient, new oil is injected into the oil tank 1 through the oil injection pipe 26 installed on the top of the upper housing 22 to ensure normal operation of the device. The spun yarn enters the device through a through-slot 23 opened on one side of the lower housing 21 and the upper housing 22. The size of the through-slot 23 is designed according to the diameter of the spun yarn to ensure smooth passage. The extrusion section 5 starts working. A limiting spring 51 is installed on the top of the upper housing 22. Under the elastic force of the limiting spring 51, the connecting disc 52 drives the pressure rod 53 and the pressure roller 54 to move downwards, squeezing the passing spun yarn to the wiping cylinder 33 of the wiping section 3, making the spun yarn in close contact with the surface of the wiping cylinder 33. The motor 31 of the wiping section 3 starts, and the motor 31 drives the rotating rod 32 to rotate through the coupling. The wiping cylinder 33, which is sleeved and fixed on the surface of the rotating rod 32, rotates accordingly. The wiping cylinder 33 is made of oil-absorbing materials such as sponge. During rotation, it comes into contact with the oil in the oil storage tank 1, absorbing the oil on its surface. When it comes into close contact with the spinning process, it evenly coats the spinning surface with oil. The scraper part 4 installed on the inner wall of the lower housing 21 cleans the surface of the wiping cylinder 33. The connecting spring 43 and the telescopic rod 44 are installed on the inner wall of the lower housing 21, and their ends are connected to the arc-shaped scraper 41. The shape of the arc-shaped scraper 41 is adapted to and fits tightly against the surface of the wiping cylinder 33. When the wiping cylinder 33 rotates, the arc-shaped scraper 41, under the action of the connecting spring 43 and the telescopic rod 44, scrapes off the oil and impurities on the surface of the wiping cylinder 33 after contact with the spinning process. The scraped-off oil flows into the lower housing 21 for temporary storage through the drain hole 42 opened through the top of the arc-shaped scraper 41. A shield 7 is installed on the inner wall of the lower housing 21. The shield 7 has a notch 71 on its side, and a filter plate 8 is installed inside the notch 71. The filter plate 8 is made of filter materials such as filter screen. The oil temporarily stored in the lower housing 21 is filtered by the filter plate 8 to remove impurities, and then flows into the oil storage tank 1 through the oil leakage groove 11 opened on the side of the oil storage tank 1 at the shield 7, realizing the recycling of oil. The oil storage tank 1 is provided with a limiting part 6, and the mounting plate 65 is fixedly installed on the bottom wall of the oil storage tank 1. The support spring 64 is installed on the top of the mounting plate 65, and the support plate 61 is horizontally set in the oil storage tank 1. When oil is injected into the oil storage tank 1, the oil exerts pressure on the support plate 61, which compresses the support spring 64; as the oil is consumed, the oil volume decreases, the oil pressure on the support plate 61 decreases, and the support spring 64 pushes the support plate 61 to rise, always keeping the oil in contact with the wiping part 3, ensuring that the wiping part 3 continuously draws oil. Meanwhile, a sealing ring 62 is fitted onto the surface of the support plate 61. The sealing ring 62 is made of sealing materials such as rubber. When the support plate 61 moves up and down, the sealing ring 62 fits tightly against the inner wall of the oil tank 1 to prevent oil leakage. A limiting ring 63 is installed at a certain height on the inner wall of the oil tank 1. When the oil level is too low, when the support spring 64 pushes the support plate 61 to rise, the limiting ring 63 blocks the support plate 61 from continuing to rise, preventing the support plate 61 from directly contacting the wiping part 3 and avoiding damage to the wiping part 3 or affecting its normal operation.A drain pipe 24 is installed at the bottom of the lower housing 21. When impurities filtered by the filter plate 8 accumulate to a certain level, the plug 25 inserted at the bottom of the drain pipe 24 is pulled out, and the impurities are discharged out of the device through the drain pipe 24. Then, the plug 25 is reinserted to seal the drain pipe 24 to prevent oil or impurities from leaking during normal operation. When it is necessary to inspect, clean, or replace the internal components of the device, unscrew the nut 281 that is threaded to the threaded post 271 at the top of the mounting plate 28, and remove the upper housing 22 from the lower housing 21. During installation, align the mounting plate 28 of the upper housing 22 with the support plate 27 of the lower housing 21 so that the threaded post 271 passes through the mounting plate 28, and then tighten the nut 281 to complete the installation.
