Description

Technical Field

[0001] This utility model relates to the field of components for rotor airflow spinning equipment, and in particular to a sealing component for a waste discharge pipe. Background Technology

[0002] In rotor-type air-jet spinning equipment, the impurity discharge pipe, as a key component within the machine section, plays a crucial role in transporting impurities discharged from the clean air inlet channel of the spinneret to the impurity discharge duct. One end of the impurity discharge pipe is fixedly connected to the impurity discharge duct within the machine section, while the other end is movably connected to the clean air inlet channel of the spinneret. When the impurity discharge fan is operating, a negative pressure is created within the impurity discharge duct, which draws in impurities separated from the fibers and discharges them from the system.

[0003] However, because the diameter of the clean air inlet duct is slightly smaller than that of the waste air outlet, gaps inevitably exist when the two are connected. These gaps lead to airflow leakage, wasting airflow and reducing the negative pressure efficiency of the waste air outlet duct. To maintain the required negative pressure level of the system, the waste air outlet fan must operate at a higher speed, which increases both motor energy consumption and equipment operating costs. Currently, there is a lack of effective sealing solutions in existing technology to fill these gaps, resulting in reduced equipment energy efficiency and impacting economic viability.

[0004] Therefore, there is an urgent need for a solution that can effectively seal the gap between the clean air inlet channel and the waste outlet to reduce airflow leakage, reduce energy consumption, and improve the overall operating efficiency of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a sealing component for a waste discharge pipe, which solves the problem in the prior art where there is a gap between the clean air inlet channel and the waste discharge pipe opening, leading to a decrease in sealing performance.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a sealing element for a waste discharge pipe, comprising: The sealing part is a raised structure, and a cavity is formed inside it that is adapted to the air outlet of the clean air inlet channel; An attachment portion is provided on one side of the sealing portion and connected to the sealing portion. A groove is provided on the side of the attachment portion away from the sealing portion, and the groove is used to fit into the port of the discharge pipe.

[0007] Furthermore, the sealing part and the attachment part are integrally formed elastomeric structures.

[0008] Furthermore, the material of the elastomer structure is a mixture of one or more of silicone rubber, nitrile rubber, and thermoplastic polyurethane elastomer.

[0009] Furthermore, the inner diameter of the cavity is larger than the outer diameter of the air outlet of the clean air inlet channel.

[0010] Furthermore, the inner contour of the groove is adapted to the outer contour of the discharge pipe opening.

[0011] Furthermore, the depth of the groove is equal to the thickness of the discharge pipe opening.

[0012] Furthermore, the attachment portion is also provided with an avoidance mounting hole located above the sealing portion.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model discloses a sealing component for a waste discharge pipe. By designing the sealing part as a raised structure and opening a cavity in the raised structure, it forms a tight fit with the air outlet of the clean air inlet channel to ensure a sealing effect. In addition, by opening a groove on the side of the attachment part away from the sealing part for the waste discharge pipe opening to fit into, it not only ensures the guiding and positioning function during installation, but also ensures the stability after fixing.

[0014] Furthermore, this seal is convenient and flexible, as it can be directly installed on new machines or used for retrofitting old machines to upgrade existing machines in the market. Attached Figure Description

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] This utility model discloses a sealing component for a wastewater discharge pipe, comprising a sealing part 1 and an attachment part 2. The two parts can be integrally formed, either through injection molding or compression molding. Making the sealing part 1 and attachment part 2 integrally formed eliminates the risk of air leakage at the component connection point, and results in a more reasonable overall sealing stress distribution. Installation is also simpler, eliminating the need to consider alignment issues.

[0018] Of course, the sealing part 1 and the attachment part 2 can also be set as separate connections. They can be mechanically connected by snaps, threads or interference fits, or they can be bonded with adhesives, as long as they can be stably connected.

[0019] In this example, both the sealing part 1 and the attachment part 2 are elastomer structures. The elastic material used for the elastomer structure can be one or more of silicone rubber, nitrile rubber, and thermoplastic polyurethane elastomers, or a mixture thereof.

[0020] Specifically, see Figures 1 to 4 The sealing part 1 is a raised structure, with an internal cavity 101 that matches the outlet 301 of the clean air inlet channel. The inner diameter of this cavity 101 is larger than the outer diameter of the outlet 301, significantly improving installation convenience, reducing alignment accuracy requirements, and decreasing assembly resistance. Secondly, the resilience of the elastic material ensures dynamic sealing performance. Furthermore, the optimized stress distribution avoids local stress concentration, extending the service life of the seal.

[0021] In addition, the shape of the cavity 101 can be adjusted according to the shape of the air outlet 301 of the clean air inlet channel to meet the sealing requirements at the connection between the two.

[0022] An attachment part 2 is disposed on one side of the sealing part 1 and connected to the sealing part 1. A groove 201 is formed on the side of the attachment part 2 away from the sealing part 1. The outer periphery of the groove 201 is a rim, and the space formed by the rim and the groove 201 allows the discharge pipe opening 401 to be fitted into it. The inner contour of the groove 201 matches the outer contour of the discharge pipe opening 401, allowing the discharge pipe opening 401 to be embedded in the groove 201. Furthermore, the groove depth (i.e., the opening width) of the groove 201 is equal to the wall thickness of the discharge pipe opening 401, facilitating installation and positioning while achieving a stable fitting effect.

[0023] The attachment part 2 also has a clearance mounting hole 202 located above the sealing part 1 to allow clearance from mounting screws or other fasteners. The diameter of the clearance mounting hole 202 is usually 1-2 mm larger than the diameter of the matching screw to facilitate installation and adjustment. Of course, multiple clearance holes can also be provided on the attachment part 2 to accommodate the installation requirements of different models of equipment.

[0024] Through the above-described structural design and material selection, this utility model achieves the following technical effects: First, it ensures a reliable seal between the sealing part 1 and the air outlet 301 of the clean air inlet channel; second, it provides a convenient installation and positioning function through the attachment part 2; and it also considers the obstacle avoidance requirements during actual installation. The design with multiple optional solutions allows this seal to adapt to different models of equipment and various working conditions, and it has broad application prospects.

[0025] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
