[0013] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.

[0014] See also Figures 1 to 4 The utility model relates to a sealed connection structure between a dust removal air duct and a sheet metal box, comprising an air duct 1, a box 2 ( Figure 1 Shown in the figure are the parts of the box body, the side panels of the box body) and the sealing ring 5. A flange plate 6 is provided at one end of the air duct 1. A buckle 4 is installed on the air duct 1 near one end of the flange plate 6. The space between the buckle 4 and the flange plate 6 forms a box installation area. The sealing ring 5 is mounted on the air duct 1 near the inner side of the flange plate 6. The sealing ring 5 is located in the box installation area. The air duct 1 passes through the box body 2. The box body 2 and the air duct 1 are installed together at the sealing ring 5. Several limiting members are also provided on the box body 2. All the limiting members are arranged along the circumferential direction of the air duct 1 as a whole; a limiting groove that movably cooperates with the limiting member is provided on the air duct 1.

[0015] Based on the above structure, the following advantages are achieved:

[0016] Good sealing: Through the compression seal of the sealing ring, dust and air leakage can be effectively prevented, which improves the dust removal efficiency and the cleanliness of the environment.

[0017] Convenient installation and maintenance: The design of the clips and limiters simplifies the assembly process of the duct and the box, and the installation can be completed quickly without complicated tools. It is also convenient for future inspection and maintenance.

[0018] Enhanced stability: The use of limiters and limit slots increases the stability of the connection parts, and can maintain good positioning even during long-term operation or encountering external force impact, reducing the risk of wear and loosening.

[0019] The box body is provided with a through hole for the air duct to pass through.

[0020] The air duct 1 and the sealing ring 5 are coaxially arranged, which ensures the linearity of the airflow path and the optimization of the sealing effect, reduces the airflow resistance, and improves the energy efficiency of the air duct system.

[0021] On the inner side of the box 2, the air duct 1 is limited by the flange 6; on the outer side of the box 2, the air duct 1 and the box 2 are connected together by buckles, and the air duct 1 is fixedly installed on the box 2. On the inner side of the box 1, the flange 6 not only serves as a supporting structure for the air duct 1, but also plays a role in precise positioning, ensuring that the air duct 1 is accurately positioned to prevent sealing failure or mechanical wear caused by deviation.

[0022] The limiting member is at least two groups of limiting bosses for limiting the air duct 1 .

[0023] The working principle of the utility model is:

[0024] The sealing ring 5 is pre-mounted on the air duct 1, close to the inner side of the flange plate 6. This design prepares for the subsequent connection with the box body 2. The air duct 1 passes through the reserved through hole of the box body 2, and the sealing ring 5 enters the box body and is located at the interface between the air duct 1 and the box body 2. When the air duct 1 completely passes through the box body 2, the sealing ring 5 is squeezed at the contact surface between the two air ducts 1 and the box body 2, forming a tight sealing layer to prevent gas or dust from leaking from the connection. The box body 2 is provided with a plurality of stoppers evenly distributed along the circumferential direction of the air duct 1. These stoppers cooperate with the stopper grooves on the air duct 1, and the air duct 1 is fixed axially and radially in the box body 2 by sliding in or snapping. This not only ensures the stability of the position of the air duct 1, but also further enhances the sealing effect, prevents the sealing failure caused by vibration, and the air duct 1 and the box body 2 form a connection structure that is both sealed and stable, realizing a reliable connection between the air duct and the sheet metal box body.

[0025] The utility model integrates sealing, installation convenience and structural stability, and is suitable for industrial applications requiring efficient dust removal and maintaining an airtight environment.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
