Description

Technical Field

[0001] This utility model belongs to the field of spinning equipment, and specifically relates to a side-blowing rectifier device for chemical fiber spinning equipment. Background Technology

[0002] The side-blowing air rectifier is a crucial piece of equipment in a chemical fiber spinning production line. It is primarily used to uniformly and stably cool and solidify the high-temperature molten nascent fiber bundles just extruded from the spinneret. Its core function is to create a highly uniform, stable, and low-turbulence cooling airflow field. The air mesh component is the most critical and technologically advanced part of the side-blowing air rectifier, directly determining the uniformity and stability of the airflow, thus affecting the cooling effect and final quality of the fibers.

[0003] Side-blowing air rectifiers typically consist of a perforated plate, a pressure equalizing mesh, a honeycomb rectifier plate, and an air distribution mesh. The edges of the perforated plate, pressure equalizing mesh, honeycomb rectifier plate, and air distribution mesh are fixed by a frame. Existing side-blowing air rectifiers mostly use front and rear flanges to fix the air distribution mesh at both ends, with a frame separating the air distribution mesh between the front and rear flanges, and fixed with multiple bolts in both the front and rear directions.

[0004] The extensive use of bolts in both the front and rear directions results in significant time consumption and inconvenience during assembly, disassembly, and maintenance. Furthermore, the excessive number of bolts makes the side-blowing rectifier prone to loosening after prolonged operation due to high-speed airflow and the interaction of various components, leading to decreased equipment stability. Loose bolts also compromise the surface flatness of the air distribution mesh, causing turbulence, affecting spinning quality, and failing to meet various spinning requirements. The excessive number of bolt holes in the frame structure also reduces the strength of the frame plates, making them prone to deformation and shortening their service life. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a side-blowing rectifier device that provides reliable sheet strength and stable spinning quality.

[0006] This utility model is achieved through the following technical solution:

[0007] A side-blowing rectifier for a chemical fiber spinning equipment includes a front flange, an air distribution mesh, and a honeycomb frame from front to back.

[0008] The front flange has a first protrusion on its rear side and a first groove on its front side. When the front flange is close to the air distribution net, the first protrusion is embedded in the first groove. The air distribution net has a second protrusion on its rear side and a second groove on its front side. When the air distribution net is close to the honeycomb frame, the second protrusion is embedded in the second groove. The front flange, the air distribution net, and the honeycomb frame are fixed by a first bolt. The first bolt passes through the front flange and the air distribution net in sequence and is screwed into the bolt hole on the upper frame of the honeycomb frame.

[0009] Furthermore, at least one first boss includes a pair of first bosses with a triangular cross-section and a solid structure. The pair of first bosses are distributed parallel to each other on the rear side of the four front flange frames and are integrally formed with the four front flange frames.

[0010] Furthermore, at least one first groove includes a pair of first grooves, which are distributed parallel to each other on the front side of the four wind distribution mesh frames of the wind distribution mesh. The cross-section of the first groove is a triangular hollow groove and its shape matches the first boss.

[0011] Furthermore, at least one second protrusion includes a pair of second protrusions, which are distributed parallel to each other on the rear side of the four wind distribution network frames, and the cross-section of the second protrusion is a hollow triangular protrusion.

[0012] Furthermore, at least one second groove includes a pair of second grooves, and the second grooves are hollow grooves with triangular cross-sections integrally formed from the honeycomb frame, and their shapes match those of the second protrusions. The second grooves are distributed parallel to each other on the front sides of the four honeycomb frame edges of the honeycomb frame.

[0013] Furthermore, the cellular rectifier is fixedly embedded inside the cellular frame.

[0014] Furthermore, the side-blowing rectifier also includes a protective net assembly, a pressure equalizing net, a pressure equalizing frame, a perforated plate assembly, and a partition plate; the protective net assembly is divided into a first protective net and a second protective net, and the perforated plate assembly is divided into a first perforated plate and a second perforated plate; the first protective net, the pressure equalizing net, the pressure equalizing frame, the second protective net, the first perforated plate, the partition plate frame, and the second perforated plate are arranged sequentially behind the honeycomb frame.

[0015] Furthermore, the side-blowing rectifier also includes a second bolt, which passes sequentially through the second perforated plate, the partition frame, the first perforated plate, the second protective net, the pressure equalizing frame, the pressure equalizing net, the first protective net, and is screwed into the honeycomb frame.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. By setting bosses and grooves between the front flange and the air distribution mesh, and between the air distribution mesh and the honeycomb frame to replace some bolts, the bolt holes on the sheet metal are reduced, which is aesthetically pleasing and lowers the process requirements of the sheet metal, while ensuring the structural strength and service life of the sheet metal.

[0018] 2. By replacing some bolts with bosses and grooves between the front flange and the air distribution net, and between the air distribution net and the honeycomb frame, the physical structure can better fix the air distribution net, ensuring that the air distribution net remains flat even under high-speed airflow, reducing turbulence and stabilizing spinning quality.

[0019] 3. By setting up a complementary positioning structure, the number of bolts is reduced, and the number of bolts that need to be removed during assembly and maintenance is greatly reduced, thus improving assembly and maintenance efficiency.

[0020] 4. By setting up protective nets between each frame, impurities in the airflow can be filtered out, turbulence can be reduced, and the airtightness between each frame can be ensured, thus ensuring stable airflow and improving spinning quality. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figure 1 and Figure 2 As shown, a side-blowing air rectifier device for a chemical fiber spinning equipment according to an embodiment of the present invention is installed at the air outlet of a side-blowing air cooling system for side-mounted horizontal air cooling. It is used to air-cool the passing melt stream to form a solid. The side-blowing air rectifier device includes a front flange 1, an air distribution mesh 2, a honeycomb rectifier plate 3, a protective mesh assembly 5, a pressure equalization mesh 6, and a perforated plate assembly 8, which are tightly connected from front to back. They are fixedly connected to each other by a frame assembly (described later). The frame assembly includes a honeycomb frame 4, a pressure equalization frame 7, and a partition frame 9. The honeycomb rectifier plate 3 is fixedly embedded inside the honeycomb frame 4.

[0032] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the rear side 12 of the front flange 1 is provided with at least one first boss 121. The at least one first boss 121 includes a pair of first bosses 121, and the cross-section of the first boss 121 is a solid triangular structure. The pair of first bosses 121 are distributed parallel to each other on the rear side 12 of the four front flange frames 13 of the front flange 1 and are integrally formed with the four front flange frames 13. The air distribution net 2 has a front side 21 and a rear side 22. The front side 21 of the air distribution net 2 is provided with at least one first groove 211. The at least one first groove 211 includes a pair of first grooves 211 and is integrally formed with the air distribution net frame 23. The pair of first grooves 211 are distributed parallel to each other on the front side 21 of the four air distribution net frames 23. The cross-section of the first groove 211 is a hollow triangular groove and its shape matches the first boss 121. When the rear side 12 of the front flange is placed opposite the front side 21 of the air distribution net, the first protrusion 121 on the rear side of the front flange can be tightly and correspondingly embedded in the first groove 211 on the front side 21 of the air distribution net. The rear side 22 of the air distribution net 2 is provided with at least one second protrusion 221, which includes a pair of second protrusions 221 and is integrally formed with the air distribution net frame 23. The pair of second protrusions 221 are distributed parallel to each other on the rear side 22 of the four air distribution net frames 23. The cross-section of the second protrusion 221 is a hollow protrusion with a triangular shape. The front side 41 of the honeycomb frame 4 is provided with at least one second groove 411, including a pair of second grooves 411. The second grooves 411 are hollow grooves with a triangular cross-section integrally formed with the honeycomb frame 4 and their shapes match the second protrusions 221. The second grooves 411 are distributed parallel to each other on the front side 41 of the four honeycomb frame frames 43 of the honeycomb frame. When the rear side 22 of the wind distribution net is placed opposite the front side 41 of the frame, the second protrusion 221 on the rear side 22 of the wind distribution net can be tightly and correspondingly embedded in the second groove 411 on the front side 41 of the frame. When the first bolt 11 passes through the front flange 1 and the wind distribution net 2 in sequence and is screwed into the frame bolt hole 42 on the honeycomb frame 4, the four edges of the wind distribution net 2 are clamped and fixed between the front flange 1 and the honeycomb frame 4. The first boss 121 is fitted with the first groove 211, and the second boss 221 is fitted with the second groove 411, which together coordinate and restrict the displacement of the wind distribution net 2.

[0033] To limit the displacement of the uniform air distribution mesh 2, in this embodiment, at least one first boss 121, at least one first groove 211, at least one second boss 221, and at least one second groove 411 are each provided in pairs, parallel to the respective frame and distributed on both sides of the bolt holes on the front flange 13, the uniform air distribution mesh 11, and the honeycomb frame 9. By using the physical structure of the bosses and grooves to limit the displacement of the uniform air distribution mesh 2, the flatness of the uniform air distribution mesh 2 is maintained, the occurrence of turbulence is reduced, and the spinning quality is more stably guaranteed. At the same time, the number of bolts required to fix the uniform air distribution mesh 2 and the number of bolt holes corresponding to the bolts on the honeycomb frame 4 are reduced. The reduction in the number of bolt holes ensures the structural strength of the honeycomb frame 4 constituting the plate, and while being aesthetically pleasing, it also reduces the process requirements for plate manufacturing. The more stable structural strength of the honeycomb frame 4 also extends its service life. When assembling the air distribution net 2, simply place the front flange 1, air distribution net 2, and honeycomb frame 4 tightly together, with the first protrusion 121 and the first groove 211, and the second protrusion 221 and the second groove 411 interlocking. Then, pass the first bolt 11 through the front flange 1 and air distribution net 2 and screw it into the honeycomb frame 4 to assemble the air distribution net 2. For disassembly and maintenance, only the bolts on the front flange 1 need to be removed to remove the front flange 1 and the air distribution net 2. This significantly reduces the number of bolts required for installation or disassembly, making it more convenient and faster, and improving the efficiency of assembly, maintenance, and disassembly.

[0034] like Figure 7 and Figure 8 As shown, the protective net assembly 5 includes a first protective net 51 and a second protective net 52, and the perforated plate assembly 8 includes a first perforated plate 81 and a second perforated plate 82. In this example, the protective net assembly 5 is preferably made of wool felt. The first protective net 51, the equalizing net 6, the equalizing frame 7, the second protective net 52, the first perforated plate 81, the partition frame 9, and the second perforated plate 82 are sequentially arranged behind the honeycomb frame 4. The honeycomb frame 4, the equalizing frame 7, and the partition frame are fixed by a second bolt 71; specifically, the second bolt 71 passes sequentially through the second perforated plate 82, the partition frame 9, the first perforated plate 81, the second protective net 52, the equalizing frame 7, the equalizing net 6, and the first protective net 51 and is screwed into the honeycomb frame 4. The first perforated plate 81 and the second perforated plate 82 are fixed to the front and rear sides of the partition frame 9 by a third bolt 91 and a fourth bolt 92, respectively.

[0035] The first protective net 51 and the equalizing net 6 are disposed between the honeycomb frame 4 and the equalizing frame 7. When the honeycomb frame 4 and the equalizing frame 7 are fixed, the four edges of the first protective net 51 and the equalizing net are clamped between the honeycomb frame 4 and the equalizing frame 7. The second protective net 52 is disposed between the equalizing frame 7 and the partition frame 9. When the equalizing frame 7 and the partition frame 9 are fixed, the four edges of the second protective net 52 are clamped between the equalizing frame 7 and the partition frame 9. By setting the first protective net and the second protective net between the honeycomb frame 4, the equalizing frame 7, and the partition frame 9, impurities in the high-speed airflow during the operation of the side-blowing rectifier can be filtered, reducing the occurrence of turbulence and improving the spinning quality.

[0036] When assembling the uniform air distribution net 2, simply place the front flange 1, the uniform air distribution net 2, and the honeycomb frame 4 tightly together, with the first protrusion 121 and the first groove 211, and the second protrusion 221 and the second groove 411 interlocking. Then, screw the bolts into the bolt holes on the front flange 1 to assemble the uniform air distribution net 2. For disassembly and maintenance, only the bolts on the front flange 1 need to be removed to remove both the front flange 1 and the uniform air distribution net 2. This significantly reduces the number of bolts required for installation or disassembly, making it more convenient and faster, and improving the efficiency of assembly, maintenance, and disassembly. By setting the protrusion and groove structure, the number of bolt holes on the honeycomb frame 4 is reduced, ensuring both aesthetics and the structural strength and service life of the honeycomb frame 4. The physical structure provides better fixation for the uniform air distribution net, ensuring it remains flat even under high-speed airflow, reducing turbulence, and stabilizing spinning quality.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
