Description

Technical Field

[0001] This utility model belongs to the field of fiber oiling, and specifically relates to a filtration device that facilitates fiber oiling. Background Technology

[0002] In existing technologies, the spraying process of chemical fiber plays a crucial role in the production of polyester staple fiber. The uniform and stable adhesion of chemical fiber auxiliaries to the fiber surface imparts key properties such as smoothness and antistatic properties, which are decisive for improving the fiber's performance in subsequent textile processing. However, in actual production scenarios, various problems frequently arise in the chemical fiber auxiliary spraying process due to multiple factors. Among these, the most prominent are surface-level spraying and intermittent spraying. Once intermittent spraying occurs, insufficient chemical fiber auxiliaries are applied to certain areas of the fiber, resulting in uneven fiber surface properties, severely affecting the fiber's physical and chemical properties, and ultimately leading to a significant decline in fiber product quality. The key factor causing intermittent spraying is the introduction of impurities into the oil pipes transporting the chemical fiber auxiliaries. These impurities easily cause nozzle blockage when flowing through the fiber spray nozzles, hindering the normal spraying of auxiliaries. Therefore, there is an urgent need to solve the problem of nozzle blockage caused by chemical fiber auxiliary oils. Utility Model Content

[0003] The purpose of this invention is to provide a filtration device that facilitates oiling of fibers, which can prevent clogging of the nozzle during oil spraying, prevent intermittent spraying during the fiber oiling process, significantly improve the quality and stability of fiber oiling, and ensure that the performance of fiber products meets the standards.

[0004] The purpose of this utility model is achieved as follows: a filter device for facilitating oiling of fibers includes an oil tank, the outlet of which is connected to the inlet of a circulating pump, the outlet of which is connected to the inlet of a filter via a first pipe, the outlet of which is connected to a first tee connector via a second pipe, and the other two ends of the first tee connector are each connected to an oil spray pipe, the ends of which are closed, and a plurality of nozzles are sequentially connected to the sides of the oil spray pipe. A second tee connector and a third tee connector are respectively provided on the first pipe and the second pipe, and a bypass pipe is provided between the sides of the second tee connector and the third tee connector, and at least one shut-off valve is provided on the bypass pipe.

[0005] In operation, this invention uses a circulating pump to draw oil from the tank into a filter. The filter screen is covered with a layer of non-woven fabric, which filters the oil. The filtered oil then enters two spray pipes and is applied to the fibers through nozzles. While the oil flows through pipes one and two to apply oil to the fibers, the shut-off valve on the bypass pipe is closed. If the filter becomes clogged, the shut-off valve on the bypass pipe is opened. This invention prevents nozzle clogging during oil application, avoids intermittent spraying during fiber application, significantly improves the quality and stability of fiber oiling, and ensures that the fiber product performance meets standards.

[0006] Compared with existing technologies, the beneficial effects of this invention are as follows: Installing a basket filter at the front end of the fiber nozzle oil pipe effectively intercepts larger particulate impurities in the oil, such as mechanical debris and undissolved additive clumps mixed in during production. This prevents these larger impurities from entering the fiber nozzle oil pipe at the source, ensuring smooth operation of the oil pipe. To further improve the filtration effect and meet the extremely high purity requirements of polyester staple fiber production, an additional layer of high-performance non-woven fabric is wrapped around the cylindrical filter screen (filter basket). This non-woven fabric has a unique fiber structure and microporous characteristics, with extremely small micropores that can capture micron- or even submicron-sized impurities in the oil, such as tiny colloidal particles, bacteria, and microorganisms. Through the dual filtration mechanism of the non-woven fabric and the filter basket, a complete filtration system from coarse to fine filtration is formed, greatly improving the purity of the oil. Furthermore, the structural design of the basket filter fully considers the ease of operation and maintenance needs in actual production. The filter's top cover features a quick-release design, connected by a swingable locking screw. Operators can quickly open the cover to easily remove the filter basket and replace the non-woven fabric, significantly reducing equipment maintenance time and improving production efficiency. Simultaneously, the filter is equipped with a pressure monitoring gauge to monitor internal pressure changes in real time. When the pressure exceeds a set threshold due to impurities, the pressure monitoring device immediately issues an alarm, reminding operators to perform timely cleaning and maintenance, ensuring the filter always operates in a highly efficient and stable state.

[0007] As a further improvement of this utility model, three shut-off valves are provided at intervals on the bypass pipe, and the shut-off valves are manual shut-off valves.

[0008] As a further improvement of this utility model, a shut-off valve is provided on pipe one after the second tee joint, and a shut-off valve is also provided on pipe two before the third tee joint. A shut-off valve is provided on the fuel injection pipe before each nozzle. The shut-off valves facilitate the control of the opening and closing of pipes one and two.

[0009] As a further improvement of this utility model, a pressure gauge is installed on the second pipe in front of the first tee joint. The pressure gauge monitors the pressure changes inside the pipe in real time.

[0010] As a further improvement of this utility model, the filter is a basket filter, which includes a vertical main cylinder. The upper end of the main cylinder is provided with a flange. The outer side of the main cylinder is provided with corresponding left and right inlet cylinders and outlet cylinders. A cylindrical filter screen is correspondingly provided inside the main cylinder. The upper end of the cylindrical filter screen is provided with an arc-shaped handle. A cover plate is provided corresponding to the upper end of the main cylinder. A number of mounting seats are provided around the outer periphery of the main cylinder corresponding to the flange. Locking screws are hinged on the mounting seats. A number of lower edge grooves are opened around the outer periphery of the flange corresponding to each mounting seat. A number of upper edge grooves are opened on the cover plate corresponding to each lower edge groove. Each upper edge groove, each lower edge groove and each mounting seat are vertically corresponding. The cover plate covers the upper opening of the main cylinder. When the cover plate is locked, the locking screw passes through the corresponding lower edge groove and upper edge groove in sequence. A locking nut for pressing the cover plate is sleeved on the upper end of the locking screw. When you need to clean the cylindrical filter screen, loosen the locking nut, then swing the locking screw downwards, and finally remove the cover plate to clean it.

[0011] As a further improvement of this utility model, the cylindrical filter screen is made of stainless steel, and its outer periphery is covered with a layer of non-woven fabric. The non-woven fabric weighs 200g / m² and can finely filter oil.

[0012] As a further improvement of this utility model, the mounting base includes two symmetrically arranged sub-bases, with a horizontal connecting shaft between the two sub-bases, and a locking screw rotatably connected to the connecting shaft. Attached Figure Description

The outlet of the circulating pump 2 is connected to the inlet of a filter 4 via a first pipe 3. The outlet of the filter 4 is connected to a first tee connector 6 via a second pipe 5. Both ends of the first tee connector 6 are connected to an oil spray pipe 7, which is closed at one end. Several nozzles 8 are sequentially connected to the sides of the oil spray pipe 7. A second tee connector 9 and a third tee connector 10 are respectively installed on the first pipe 3 and the second pipe 5. A bypass pipe 11 is provided between the sides of the second tee connector 9 and the third tee connector 10. At least one shut-off valve 12 is installed on the bypass pipe 11. Three shut-off valves 12 are spaced apart on the bypass pipe 11. The shut-off valves 12 are manual shut-off valves. A shut-off valve 12 is installed on pipe 3 after the second tee joint 9, and a shut-off valve 12 is also installed on pipe 5 before the third tee joint 10. A shut-off valve 12 is also installed on the fuel injection pipe 7 before each nozzle 8. The shut-off valves 12 facilitate the control of the opening and closing of pipes 3 and 5.

[0019] A pressure gauge 13 is installed on pipe 25, upstream of the first tee joint 6. The pressure gauge monitors the pressure changes inside the pipe in real time.

[0020] The filter 4 is a basket filter 4, which includes a vertical main cylinder 401. A flange 14 is provided at the upper end of the main cylinder 401. A corresponding inlet cylinder 15 and outlet cylinder 16 are provided on the outer side of the main cylinder 401. A cylindrical filter screen 17 is correspondingly installed inside the main cylinder 401. An arc-shaped handle 17a is provided at the upper end of the cylindrical filter screen 17. The cylindrical filter screen 17 is made of stainless steel, and its outer periphery is covered with a layer of non-woven fabric 23. The non-woven fabric 23 weighs 200g / m² and can finely filter oil. A cover plate 402 is provided corresponding to the upper end of the main cylinder 401. A plurality of circumferentially distributed mounting seats 18 are provided on the flange 14. Locking screws 19 are hinged to the mounting seats 18. A plurality of circumferentially distributed lower edge grooves 20 are formed on the outer periphery of the flange 14 corresponding to each mounting seat 18. A plurality of upper edge grooves 21 are formed on the cover plate 402 corresponding to each lower edge groove 20. Each upper edge groove 21, each lower edge groove 20, and each mounting seat 18 are vertically aligned. The cover plate 402 correspondingly covers the upper opening of the main cylinder 401. When the cover plate 402 is locked, the locking screws 19 pass upwards through the corresponding lower edge grooves 20 and upper edge grooves 21 in sequence. A locking nut 22 is fitted onto the upper end of the locking screw 19 to press against the cover plate 402. When cleaning the cylindrical filter screen 17, the locking nut 22 is loosened, the locking screw 19 is then swung downwards, and finally the cover plate 402 is removed for cleaning.

[0021] Mounting base 18 includes two left-right symmetrical sub-bases 18a, with a horizontal connecting shaft 24 between the two sub-bases 18a, and a locking screw 19 is rotatably connected to the connecting shaft 24.

[0022] In operation, the circulating pump 2 draws oil from the oil tank 1 into the filter 4. The filter screen of the filter 4 is covered with a layer of non-woven fabric 23. The oil is filtered through the non-woven fabric 23 and the filter screen. The filtered oil then enters the two spray pipes 7 and is applied to the fibers through the nozzles 8. When the oil flows through pipes 1 (3) and 2 (5) to apply oil to the fibers, the shut-off valve 12 on the bypass pipe 11 is closed. If the filter 4 becomes clogged, the shut-off valve 12 on the bypass pipe 11 is opened. This invention can prevent clogging of the nozzles 8 during oil spraying, prevent intermittent spraying during fiber oiling, significantly improve the quality and stability of fiber oiling, and ensure that the fiber product performance meets standards.

[0023] This invention installs a basket filter 4 at the front end of the oil pipe of the fiber nozzle 8, which can effectively intercept larger particulate impurities in the oil, such as mechanical debris and undissolved additive clumps mixed in during production. This prevents these larger impurities from entering the oil pipe of the fiber nozzle 8 at the source, ensuring the smooth operation of the oil pipe. To further improve the filtration effect and meet the extremely high purity requirements of polyester staple fiber production, an additional layer of high-performance non-woven fabric 23 is wrapped around the outside of the cylindrical filter screen 17 (filter basket). This non-woven fabric 23 has a unique fiber structure and microporous characteristics. Its micropores are extremely small, which can capture micron- or even submicron-sized fine impurities in the oil, such as tiny colloidal particles, bacteria, and microorganisms. Through the dual filtration mechanism of the non-woven fabric 23 and the filter basket, a complete filtration system from coarse to fine filtration is formed, greatly improving the purity of the oil. In addition, the structural design of the basket filter 4 fully considers the ease of operation and maintenance needs in actual production. The top cover of filter 4 features a quick-release design, connected by a swingable locking screw 19. Operators can quickly open the top cover to easily remove the filter basket and replace the non-woven fabric 23, significantly reducing equipment maintenance time and improving production efficiency. Simultaneously, filter 4 is equipped with a pressure monitoring gauge to monitor internal pressure changes in real time. When the pressure inside filter 4 exceeds the set threshold due to impurities, the pressure monitoring device will immediately issue an alarm, reminding operators to perform timely cleaning and maintenance, ensuring filter 4 always operates in a highly efficient and stable state.
