Description

Technical Field

[0001] This utility model relates to dust removal, specifically a dust removal device for carpet weaving. Background Technology

[0002] During the carpet weaving process, fibers inevitably get mixed in with the air. Unlike dust, fibers cannot be filtered by the nasal system, which causes them to accumulate in the nasal cavity and enter and exit the respiratory tract. Over time, this can lead to complications such as rhinitis.

[0003] The purpose of dust removal equipment is to reduce the fiber content and dust in the air during the production process, thereby ensuring the safety of employees.

[0004] Referring to Chinese authorized patent, publication number CN107670445B, publication date 2019-05-24, a dust removal device for textile machines is disclosed, including a box with an open lower cavity structure, a double-acting cylinder, and a control cabinet. A rotating shaft penetrating both ends of the box is provided within the cavity of the box. A rotary motor is externally connected to the rotating shaft. A roller with an internal cavity structure is fixedly connected to the rotating shaft. Several circumferential ventilation holes are provided on the arc surfaces at both ends of the roller. A dust discharge window is also provided on the roller, located between the ventilation holes at both ends. Two sleeves are provided on the surface of the roller, and the two sleeves are respectively fixedly connected to the two piston rods of the double-acting cylinder. A vibration motor is also fixedly connected to the sleeves. Two supports arranged axially along the roller are provided within the cavity of the roller. The purpose of this invention is to provide a dust removal device for textile machines to solve the problems of poor dust removal effect and failure to eliminate the negative charge of dust in existing dust removal devices.

[0005] In existing technologies, including the aforementioned patents, dust removal in factories such as carpet weaving differs from dust filtration. In addition to dust pollution, the air also contains fibers floating in the air. These fibers cannot enter the filter media and only remain on the surface. Over time, the filter media surface will become clogged, preventing it from functioning properly. Utility Model Content

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a dust removal device for carpet weaving, including the following embodiments:

[0033] Example 1

[0034] Combination Figure 1 - Figure 4 As shown, the dust removal device includes a first filter tank shell 3, a second filter chamber 6, and a first flange 31. Specifically:

[0035] The top of the first filter housing 3 is open, and the foamed wire stamping block 1 is embedded through the open. Then, the first flange 31 is threadedly connected to the inner wall of the open of the first filter housing 3 for a fixed seal. Furthermore, the side of the first filter housing 3 opposite to the open has an integrally formed internal threaded connection part 5, and the outer wall of the internal threaded connection part 5 is fixedly connected to an air outlet pipe 51.

[0036] The non-woven filter material assembly 2 is assembled inside the second filter chamber 6 and fixed to the second filter chamber 6 by the annular fastener 22. The second filter chamber 6 is fixed and sealed to the internal threaded connection part 5 by threaded connection.

[0037] It should be noted that the aforementioned nonwoven filter media assembly 2 is used to filter the airflow passing through the foamed yarn stamping block 1. The nonwoven filter media assembly 2 consists of multiple layers of nonwoven fabric pockets 21 arranged sequentially from the inside out.

[0038] Furthermore, a plurality of air guide pipes 32 arranged in a circular array are fixedly connected to the outer end face of the first flange 31, and the plurality of air guide pipes 32 are fixedly connected to the air inlet pipe 33 on the first flange 31.

[0039] Furthermore, the foamed fiber stamping block 1 is functionally divided into an air receiving groove 11 and an air permeable groove 12 located on the axis of the air receiving groove 11.

[0040] In the specific implementation process, an external fan (not shown in the figure, which can be connected to the air inlet pipe 33 or integrated) operates, drawing the airflow containing dust, fibers, and odors generated in the factory or production equipment into the air inlet pipe 33. The airflow is distributed to multiple air guide pipes 32 via the air inlet pipe 33. Since the outlet of the air guide pipe 32 is narrow, the airflow is accelerated here and injected at high speed into the air receiving groove 11 area of ​​the foamed fiber stamping block 1. The foamed fiber structure can effectively intercept larger particles of fiber and lint in the airflow, completing the first stage of filtration. The airflow after preliminary filtration penetrates the foamed fiber and enters the lower space inside the first filter tank shell 3. In the double-layer filtration system, the foamed fiber stamping block 1 is used to intercept fibers, while the non-woven filter material group 2 is used to remove odors and intercept dust in the airflow.

[0041] Example 2

[0042] Based on the above embodiment one, this embodiment aims to design the airflow guidance between the foamed fiber stamping block 1 and the non-woven filter material assembly 2. Specifically, in conjunction with... Figure 4As shown, the outer wall of the air duct 7 has an external threaded end, which passes through the threaded tube arranged axially on the first filter housing 3 and is fixed by the external threaded end. After installation, one end of the air duct 7 extends from the inner ring of the annular constrictor 22 to below the port of the non-woven fabric pocket 21, while the other end of the air duct 7 passes through the through hole opened on the foamed fiber stamping block 1 and extends into the air permeable groove 12. That is, the scheme uses an inverted design of the non-woven fabric filter material group 2 to filter the airflow after the foamed fiber stamping block 1.

[0043] Furthermore, the second filter chamber 6 has a frustum-shaped structure, which has a narrow opening and a wide opening. The port of the air guide duct 7 is located near the narrow opening. That is to say, the airflow introduced by the air guide duct 7 enters the narrow opening of the filter chamber 6, and then, as the airflow continues to flow, it moves upward and passes through the second filter chamber 6 for dust removal and filtration.

[0044] The multi-layer nonwoven fabric pocket 21 has at least three layers: the outermost layer is polyester fiber nonwoven fabric, the middle layer is activated carbon nonwoven fabric, and the innermost layer is polypropylene nonwoven fabric. This achieves odor removal and dust removal filtration. The air duct 7 guides the airflow from the narrow end (bottom) of the second filter chamber 6, directly delivering it to the area below the inlet of the nonwoven fabric filter material group 2. The airflow then flows upward, sequentially penetrating the inner layer, the middle layer (activated carbon), and the outer layer of the nonwoven fabric pocket 21 for fine dust removal and odor removal. The filtered clean airflow gathers in the wide end (top) space of the second filter chamber 6.

[0045] In the specific implementation process, the outermost polyester fiber nonwoven fabric is bonded to the inner wall of the second filter chamber 6 and the outer wall of the air duct 7. The airflow is discharged through the bottom of the polyester fiber nonwoven fabric. The bonding is performed using environmentally friendly industrial adhesive.

[0046] After the first-stage filtration (foamed fiber interception) in Example 1, the airflow located below the first filter tank 3 is drawn into the interior of the air duct 7 through the upper port of the air duct 7 under the negative pressure of the fan. The airflow descends along the air duct 7 and exits from its lower outlet, entering the bottom space of the narrow end of the second filter chamber 6. The airflow then flows upward, first entering the inner polypropylene nonwoven fabric pocket 21 of the nonwoven filter material group 2 to filter out finer dust; then penetrating the middle activated carbon nonwoven fabric to adsorb and remove odors; and finally passing through the outer polyester fiber nonwoven fabric for deep filtration. The clean airflow after completing the second-stage filtration fills the wide end (top) area of ​​the second filter chamber 6 and is finally discharged from the device through the air outlet duct 51 fixed to the outer wall of the internal threaded connection part 5.

[0047] Example 3

[0048] Based on the above embodiment 1, the bottom of the foaming fiber stamping block 1 is flat, while the inside of the first filter tank shell 3 is arc-shaped, so a partition cavity 8 is formed between the two.

[0049] Furthermore, the soft rubber cap 4 is distributed on the port cross-section of the air receiving groove 11 and the air venting groove 12, and the portion distributed on the air receiving groove 11 is provided with a through groove, and the air outlet of the air guide pipe 32 is distributed at the center of the through groove.

[0050] Furthermore, the air duct 32 is frustoconical and has a narrow opening and a wide opening, with the narrow opening connected to the air receiving groove 11.

[0051] Specifically, when the airflow enters the air receiving groove 11 of the foamed fiber stamping block 1 through the air guide pipe 32, the airflow velocity increases due to the reduced cross-section of the output port, resulting in stronger airflow penetration. The foamed fiber stamping block 1 has a sparse structure, formed by bending and stamping a single foamed fiber. The perforations should be maintained between 1mm and 1.5mm. The high-speed airflow is ejected from the narrow opening of the air guide pipe 32, directly impacting the air receiving groove 11 area of ​​the foamed fiber stamping block 1. The high-speed airflow imparts greater kinetic energy to the fiber / dust particles, making it easier for them to penetrate the sparsely structured (1mm-1.5mm perforations) foamed fiber layer, rather than merely remaining on its surface. The airflow after penetrating the foamed fiber (potentially carrying a small amount of fine fibers that were not completely intercepted) enters the lower partition cavity 8. The curved bottom surface facilitates airflow diffusion and buffering, reducing turbulence. The airflow gathers in the partition cavity 8, and then, under the negative pressure of the fan, is relatively smoothly drawn in through the upper port of the air guide pipe 7, entering the second-stage filtration process.

[0052] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
