Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and in particular to a geotextile extrusion cooling device. Background Technology

[0002] In the production process of geotextiles, the fine streams extruded from the spinneret need to be cooled to solidify and form the fibrous structure of the geotextile.

[0003] Existing geotextile extrusion cooling methods are relatively simple, typically employing only unidirectional air cooling. However, this method has several problems. First, the air entering the cooling device may contain impurities, which can adhere to the extruded fine stream, affecting the quality of the geotextile, leading to product defects and reducing the yield rate. Second, unidirectional air cooling has limited effectiveness in cooling the extruded fine stream, resulting in uneven cooling and potentially causing under- or over-cooling of fibers in some areas. This, in turn, affects the physical properties of the geotextile, such as strength and uniformity, failing to meet the production requirements of high-quality geotextiles. Therefore, a geotextile extrusion cooling device that can effectively filter air and provide better cooling is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the air entering the cooling device may contain impurities, which can adhere to the extruded fine stream and affect the quality of the geotextile. Therefore, this invention proposes a geotextile extrusion cooling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A geotextile extrusion cooling device includes two support frames, one end of which is fixed with the same return air plate, and the other end of which is fixed with the same air blowing plate. The air blowing plate has an air inlet groove for blowing air toward the extruded fine stream. Multiple air inlet pipes are fixedly connected to the air blowing plate, and the multiple air inlet pipes are all connected to a centrifugal fan for air supply. To ensure the quality of the extruded fine stream, a filter screen for filtering air is provided inside the blower plate. A connecting assembly is provided between the filter screen and the blower plate, and the connecting assembly is used to quickly fix the filter screen inside the blower plate. To enhance the cooling effect on the extruded fine stream, a set of return air components is provided inside the return air plate. The return air components are used to deflect the air blown out of the air inlet slot back for secondary cooling.

[0006] In one possible design, the connecting assembly includes a matching groove formed inside the blower plate and communicating with the air inlet slot. A filter frame slides in the matching groove, and the filter screen is fixed inside the filter frame. Two first grooves are formed inside the filter frame, and a locking block slides in each of the two first grooves. Two slots are formed inside the blower plate, and the two locking blocks are respectively engaged with the two slots. Springs are provided at the close ends of the two locking blocks, and the two ends of the two springs abut against the close ends of the two locking blocks and the inner walls of the two first grooves through spring seats. The spring's elasticity pushes the locking block to engage and fix it into the slot, achieving connection and positioning.

[0007] In one possible design, the bottom ends of both of the two blocks are provided with inclined grooves, which facilitate the two blocks being squeezed back into the two first grooves. The filter frame can be directly placed into the matching slot by setting two inclined slots. The card block will be squeezed by the inner wall of the matching slot. When the card block and the card slot are matched and aligned, automatic snap-fit ​​fixation can be achieved.

[0008] In one possible design, a lever is fixed to the top of each of the two blocks.

[0009] In one possible design, both of the levers have a connecting groove for easy lifting.

[0010] In one possible design, the return air assembly includes a U-shaped air distribution slot formed within the return air plate, with two air outlets of the U-shaped air distribution slot located on the upper and lower sides of the air blowing plate, respectively. The return air plate has a conical air inlet connected to the U-shaped air distribution slot, and the conical air inlet matches the air inlet slot. The air in the air inlet slot is cooled by the extruded fine streams and then enters the conical air inlet. After passing through the U-shaped air distribution slot, it is divided into two sections to cool the extruded fine streams on the upper and lower sides of the air inlet slot respectively.

[0011] In this application, the spring's elasticity pushes the card block to engage and fix it into the card slot, achieving connection and positioning. The two inclined slots allow the filter frame to be directly placed into the matching slot, and the card block is squeezed by the inner wall of the matching slot. When the card block and the card slot are matched and aligned, automatic engagement and fixation can be achieved. The air in the air inlet slot is cooled and then extruded into a fine stream before entering the conical air inlet. After passing through the U-shaped air distribution slot, it is split into two sections to cool the extruded fine streams on the upper and lower sides of the air inlet slot respectively.

[0012] Beneficial effects: In this utility model, the geotextile extrusion cooling device can filter the air entering the air inlet groove by setting a filter screen in the air blowing plate, effectively removing impurities in the air and preventing impurities from adhering to the extruded fine stream, thereby ensuring the quality of the extruded fine stream, improving the qualification rate of geotextile products, reducing the generation of defective products caused by impurities, and reducing production costs. In this utility model, the geotextile extrusion cooling device features a connecting component design that allows the filter screen to be quickly fixed inside the blower plate, making installation and disassembly convenient and quick. When cleaning or replacing the filter screen is required, the operator only needs to move the lever to disengage the locking block from the slot, allowing the filter frame to be removed from the matching slot. This greatly improves maintenance efficiency, reduces equipment downtime, and ensures production continuity. In this invention, the return air assembly enhances the cooling effect on the extruded fine streams. The air blown out of the air inlet trough cools the extruded fine streams and then enters the U-shaped air distribution trough through the conical air inlet. It is then split into two sections to provide secondary cooling to the extruded fine streams on the upper and lower sides of the air inlet trough, resulting in more uniform cooling. This effectively improves the cooling effect on the geotextile fibers, enhances the physical properties of the geotextile, and produces geotextile products with higher quality and more stable performance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figures 1-5 A geotextile extrusion cooling device, applied in the field of cooling equipment technology, is used to cool the fine stream extruded from a spinneret 1. It includes two support frames 2, arranged in parallel, one end of which is bolted to a return air plate 3, and the other end is bolted to a blowing plate 4. The blowing plate 4 is a cuboid structure with an air inlet slot 6 inside, which is elongated and used to blow air towards the extruded fine stream. Multiple air inlet pipes 5, numbering 4-6, are fixedly connected to the blowing plate 4, evenly distributed on one side. All air inlet pipes 5 are connected to a centrifugal fan for air supply, providing stable airflow to deliver air through the air inlet pipes 5 into the air inlet slot 6.

[0017] To ensure the quality of the extruded fine stream, a filter screen 11 for filtering air is provided inside the blower plate 4. A connecting assembly is provided between the filter screen 11 and the blower plate 4 to quickly fix the filter screen 11 inside the blower plate 4. Specifically, the connecting assembly includes a matching groove 9 formed inside the blower plate 4 and communicating with the air inlet slot 6. The shape of the matching groove 9 is adapted to the filter frame 10. The filter frame 10 is slidably connected inside the matching groove 9, and the filter screen 11 is fixed inside the filter frame 10 by adhesive or snap-fit. Two first grooves 12 are formed inside the filter frame 10, and the two first grooves 12 are symmetrically distributed on both sides of the filter frame 10. Each of the two first grooves 12 is slidably connected to a locking block 14, and the blower plate 4 has two locking slots 15, with the two locking blocks 14 engaging with the two locking slots 15 respectively. Each of the two locking blocks 14 has a spring 13 at its adjacent ends. The two ends of the two springs 13 abut against the adjacent ends of the two locking blocks 14 and the inner walls of the two first grooves 12 through spring seats. When the filter screen 11 is installed, the filter frame 10 is placed into the matching groove 9. The locking blocks 14 are squeezed by the inner wall of the matching groove 9 and slide into the first groove 12. The springs 13 are compressed. When the locking blocks 14 move to be aligned with the grooves 15, the elasticity of the springs 13 pushes the locking blocks 14 into the grooves 15, realizing the connection and positioning.

[0018] Both locking blocks 14 have inclined grooves 16 at their bottom ends, with an inclination angle of 30° or 45°. With the two inclined grooves 16, when installing the filter screen 11, the filter frame 10 can be directly placed into the matching groove 9. The locking blocks 14 will be pressed against the inner wall of the matching groove 9 and slide back into the two first grooves 12 along the inclined surface of the inclined groove 16. When the locking blocks 14 and the grooves 15 are aligned, the spring 13 pushes the locking blocks 14 to automatically engage and fix them.

[0019] Each of the two locking blocks 14 has a lever 17 fixed to its top. The lever 17 is a rectangular thin piece, which is convenient for manual operation by the operator. Each of the two levers 17 has a connecting groove 18 for easy lifting. The connecting groove 18 is long and narrow. The operator can pass his / her fingers through the connecting groove 18 to move the lever 17, thereby moving the locking block 14 and making it easy to remove the filter screen 11.

[0020] In another embodiment: Refer to Figures 1-5 An improvement upon Example 1 is made: to enhance the cooling effect on the extruded fine streams, a set of return air components is provided within the return air plate 3. The return air components include a U-shaped air distribution channel 7 formed within the return air plate 3. The U-shaped air distribution channel 7 is U-shaped, with its two air outlets located on the upper and lower sides of the blowing plate 4, respectively. A conical air inlet 8, connected to the U-shaped air distribution channel 7, is provided within the return air plate 3. The larger end of the conical air inlet 8 matches the air inlet channel 6, while the smaller end connects to the U-shaped air distribution channel 7. The air in the air inlet channel 6, after cooling the extruded fine streams, enters the conical air inlet 8. After passing through the U-shaped air distribution channel 7, it is divided into two sections to cool the extruded fine streams on the upper and lower sides of the air inlet channel 6, respectively.

[0021] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
