[0002] Carding machines are key pieces of equipment in the textile process, primarily used for combing, removing impurities, and blending fibers. During the carding process, a large amount of short fibers, dust, and impurities are generated. If these contaminants are not removed promptly and effectively, they will not only worsen the working environment and affect worker health, but also become entangled in the equipment, reducing carding quality and even causing equipment malfunctions. Existing dust removal devices for carding machines mostly use simple filters or dust cages, which have the following drawbacks: Low dust removal efficiency: Uneven airflow distribution in the filter components results in some filter area not being fully utilized, leading to poor filtration effect.

[0003] Easy to clog: Fiber dust easily adheres to and clogs the filter screen, requiring frequent shutdowns for manual cleaning, which affects production efficiency.

[0004] Poor cleaning effect: Traditional cleaning methods (such as rapping and backflushing) have limited effect and are difficult to completely remove fine dust embedded deep in the filter. After long-term operation, the resistance increases and the energy consumption increases.

[0005] Inconvenient maintenance: The filter components are difficult to disassemble and replace, which increases the workload and time cost of maintenance. Summary of the Invention

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] This utility model provides an embodiment, such as Figure 1 , Figure 2 As shown, a dust removal device for a carding machine is characterized by comprising: The mask 1 is installed on the carding machine and communicates with its interior. It has an exhaust fan 101 at the bottom to draw out the dust-laden air inside the carding machine and an exhaust port at the top. The dust collector 2 is a vertical cylindrical structure and is located above the exhaust mask 1. It is connected to the exhaust port through an exhaust pipe 201 arranged coaxially. The top of the dust collector 2 is provided with an outlet pipe 202 for discharging filtered clean air. An exhaust valve 203 is provided on the outlet pipe 202 for controlling the opening and closing of the system. The uniform flow filtration mechanism 3 is disposed inside the dust collection box 2 and has an axis coaxial with the exhaust pipe 201; A pulse cleaning mechanism 4 is disposed above the uniform flow filter mechanism 3. The pulse cleaning mechanism 4 is positioned toward the uniform flow filter mechanism 3 and is used to clean the uniform flow filter mechanism 3. The dust collection and discharge mechanism 5 is located at the bottom of the dust collection box 2 and is used to collect falling dust. Specifically, the flow equalization filtration mechanism 3 includes a flow equalization seat 301 in the shape of an inverted cone and a filter assembly 310 with a conical surface structure arranged along the edge of the flow equalization seat 301. The flow equalization seat 301 is coaxially arranged with the exhaust pipe 201. To facilitate the installation and disassembly of the filter assembly 310, in a further embodiment, the filter assembly 310 includes an annular base 311 that is detachably connected to the inner wall of the dust collection box 2, and the edge of the annular base 311 is connected to the inner wall of the dust collection box 2 by bolts. Multiple support rods 312 are fixedly connected to the annular base 311 and the flow equalization seat 301. The multiple support rods 312 are arranged radially and are evenly distributed along the circumference of the annular base 311. A filter screen 313 is detachably mounted on the brackets of two adjacent support rods 312; To facilitate the replacement of the filter screen 313, in a further embodiment, the support rod 312 is provided with a mounting groove 314, and the filter screen 313 is detachably disposed in the mounting groove 314. The edge of the filter screen 313 can be inserted into and locked in these mounting grooves 314, and connected to the mounting groove 314 by bolts, making the replacement of a single filter screen 313 very convenient. In order to achieve a better flow uniformity effect, in a further embodiment, a flow guide 204 extending upward to the edge of the flow uniform seat 301 is coaxially connected to the exhaust pipe 201. The flow guide 204 has an inverted conical surface structure, which can smoothly guide the high-speed incoming airflow to the inclined surface of the flow uniform seat 301. Specifically, the pulse cleaning mechanism 4 includes a pulse pipe 401 coaxially arranged with the exhaust pipe 201 and extending from top to bottom through the top of the uniform flow filter mechanism 3, a plurality of branch pipes 402 arranged radially along the pulse pipe 401 and fixedly connected thereto, and nozzles 403 arranged on the branch pipes 402 and facing the uniform flow filter mechanism 3. In this embodiment, the annular base 311 is provided with an annular slide rail, and the end of the branch pipe 402 slides in cooperation with the slide rail. In this embodiment, the branch pipe 402 is provided in two sets and located on both sides of the pulse pipe 401. The pulse pipe 401 is rotatably connected to the dust collection box 2 and a rotary joint 404 is connected to the top. The rotary joint 404 is connected to an external high-pressure air source. The outer side of the dust collection box 2 is provided with a rotary drive 405 that is pulsorily connected to the pulse pipe 401, which can drive the pulse pipe 401 together with the branch pipe 402 and the nozzle 403 to rotate. Specifically, the dust collection and discharge mechanism 5 includes a discharge cylinder 501 coaxially disposed outside the exhaust pipe 201 and communicating with the bottom of the dust collection box 2, a discharge pipe 502 disposed on the side of the discharge cylinder 501, and a discharge valve 503 disposed on the discharge pipe 502. When the carding machine is running, the discharge valve 503 is closed, the exhaust valve 203 is open, and the exhaust fan 101 is started. Dust-laden air is drawn from the carding machine through the mask 1 and enters the dust collection box 2 through the exhaust pipe 201. Guided by the guide hood 204 and the flow equalizer 301, the airflow is evenly distributed across the entire surface of the conical filter assembly 310. Air passes through the filter 313 of the filter assembly 310, and short fibers, dust, and other impurities are trapped on the outer surface of the filter. The clean air flows upward and is finally discharged from the top outlet pipe 202.

[0021] When dust accumulates on the surface of the filter assembly 310 to a certain extent, increasing system resistance and requiring cleaning, the discharge valve 503 opens, the exhaust valve 203 closes, and the pulse cleaning mechanism 4 is activated. An external high-pressure air source injects high-pressure gas instantaneously into the pulse tube 401 through the rotary joint 404. The gas is then ejected at high speed from the nozzle 403 via the branch pipe 402, forming a strong pulse airflow that blows back across the outer surface of the filter 313, removing the dust adhering to it. Simultaneously, the rotary drive 405 operates, driving the pulse tube 401 to rotate slowly, ensuring that the nozzle 403's spray range covers the entire conical filter surface, achieving comprehensive and thorough cleaning. Finally, the pulse airflow is discharged through the discharge pipe 502. The blown dust settles to the bottom of the dust collector 2 under the action of gravity and falls into the discharge cylinder 501 of the dust collection and discharge mechanism 5; and under the action of airflow, the collected dust is discharged through the discharge pipe 502, completing the entire dust collection and discharge process.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
