Description

Technical Field

[0001] This utility model relates to the field of partition door technology, specifically to a quick-opening air duct partition door. Background Technology

[0002] In the industrial production field, the air duct system is a key facility for transporting gaseous media, and the air duct partition door, as the core component for controlling the opening and closing of the air duct, directly affects the efficiency, safety and ease of maintenance of the system. Currently, traditional duct partition doors exhibit several problems in practical applications: First, their opening speed is slow. Most adopt a single-door structure design, relying on a single drive source to rotate or slide the door. Limited by structural inertia and transmission efficiency, they cannot meet the needs of scenarios requiring rapid switching of duct access, such as emergency system maintenance or urgent adjustment of media delivery paths. In severe cases, this may affect production rhythm or cause safety hazards. Second, the door's operation is easily affected by environmental interference. Dust, particles, and other debris in the duct tend to accumulate at the ends and bottom of the door track, causing obstruction to the door's rotation or sliding, which not only increases door wear. First, frequent shutdowns for cleaning are required, resulting in high maintenance costs. Second, poor sealing performance; the traditional door and frame design is unreasonable, and insufficient sealing measures at the connection between the rotating shaft and the door body make it prone to media leakage when closed, reducing the effectiveness of the duct partition. Third, insufficient stability of the drive system; some partition doors lack reliable support and positioning structures for their drive components, which can easily cause shaking and displacement after long-term operation, leading to decreased door opening and closing accuracy and even malfunctions. Therefore, designing a duct partition door that can solve the above technical problems is an urgent issue for technicians in related fields. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a quick-opening duct partition door, including a first partition door box and a second partition door box arranged opposite to each other, with a support beam respectively provided at one end of the first partition door box and the second partition door box, and a rotating opening assembly connected to the other end, so that the first partition door box and the second partition door box form a double-door partition door box; the rotating opening assembly includes a rotating shaft provided at the opposite end of the first partition door box and the second partition door box, with one end of the rotating shaft connected to the first partition door box and the second partition door box through a sealing assembly, and the other end hinged to a cylinder output shaft through a rotating arm, and a purging assembly is also provided at the opposite end of the first partition door box and the second partition door box.

[0004] Furthermore, the first partition door housing and the second partition door housing have the same structure. The first partition door housing includes a frame connected to the rotating opening assembly, the support beam is connected to the frame, and a gate is provided between the frame and the support beam.

[0005] Furthermore, a pneumatic door housing is provided outside the first partition door housing and the second partition door housing. The rotating opening component and the blowing component are both provided on the pneumatic door housing. The pneumatic door housing is provided with partition door tracks corresponding to the rotation directions of the first partition door housing and the second partition door housing.

[0006] Furthermore, the purging assembly includes a purging pipeline, the inlet end of which is connected to an external air source, and the outlet end is provided with several purging branches, the outlet ends of which correspond to the ends and bottom of the partition door track.

[0007] Furthermore, the pneumatic door housing is provided with a bearing bracket that is rotatably connected to the rotating shaft.

[0008] Furthermore, the pneumatic door housing is also equipped with a cylinder bracket connected to the cylinder and a control switch for controlling the cylinder's movement.

[0009] The advantages of this utility model compared with the prior art are as follows: This invention is simple to operate. It uses a cylinder as a power source to directly drive the door to rotate along the track via a rotating arm and rotating shaft. Compared with the traditional single-door structure, it significantly shortens the air duct switching time, increases the opening and closing speed of the partition door, and improves efficiency. The support beam and the gate form a complete partition surface, which can reliably block the air duct flow when closed, improving the safety of system operation. The purging component accurately purifies the ends and bottom of the partition door track through purging pipes and branches, promptly removing accumulated dust and debris, avoiding door jamming and wear, and reducing the frequency of manual cleaning.

[0017] Example

[0018] Combined with appendix Figure 1-2 This embodiment discloses a quick-opening duct partition door, including a first partition door housing 1 and a second partition door housing 2 arranged opposite to each other. The first partition door housing 1 and the second partition door housing 2 are respectively provided with support beams 3 at their respective ends close to each other, and the other ends are connected to a rotating opening assembly 4, so that the first partition door housing 1 and the second partition door housing 2 form a double-door partition door housing. The rotating opening assembly 4 includes a rotating shaft 401 disposed at the ends of the first partition door housing 1 and the second partition door housing 2 away from each other. One end of the rotating shaft 401 is connected to the first partition door housing 1 and the second partition door housing 2 through a sealing assembly 402, and the other end is hinged to the output shaft of a cylinder 404 through a rotating arm 403. The ends of the first partition door housing 1 and the second partition door housing 2 away from each other are also respectively provided with a purging assembly 5.

[0019] The first partition door housing 1 and the second partition door housing 2 have the same structure. The first partition door housing 1 includes a frame 101 connected to the rotating opening assembly 4. The support beam 3 is connected to the frame 101. A gate 102 is provided between the frame 101 and the support beam 3. A pneumatic door housing 6 is provided outside the first partition door housing 1 and the second partition door housing 2. The rotating opening assembly 4 and the blowing assembly 5 are both provided on the pneumatic door housing 6. The pneumatic door housing 6 is provided with partition door tracks corresponding to the rotation directions of the first partition door housing 1 and the second partition door housing 2.

[0020] The purging assembly 5 includes a purging pipe 501, the inlet end of which is connected to an external air source, and the outlet end of which is provided with several purging branches 502, the outlet ends of which correspond to the ends and bottom of the partition door track.

[0021] The pneumatic door housing 6 is provided with a bearing bracket 7 that is rotatably connected to the rotating shaft 401; the pneumatic door housing 6 is also provided with a cylinder 404 bracket connected to the cylinder 404 and a control switch for controlling the action of the cylinder 404.

[0022] I. Initial Closed State At this time, the first partition door box 1 and the second partition door box 2 are in a closed state: the two are set opposite each other, and the ends closest to each other cooperate with each other through the support beam 3. The gate 102 on the frame 101 forms a complete partition surface, blocking the flow of medium in the air duct. In the rotating opening assembly 4, the cylinder 404 is in the initial retracted state, and the rotating arm 403 and the rotating shaft 401 remain stable under the support of the bearing bracket 7. The rotating shaft 401 is connected to the partition door body through the sealing assembly 402 to ensure the air duct is sealed. The purging assembly 5 is in standby mode, the purging pipeline 501 is connected to the external air source, and the purging branch 502 is aligned with the end and bottom of the partition door track.

[0023] II. Opening Process An opening command is issued by the control switch on the pneumatic door housing 6 to control the cylinder 404 to move; the output shaft of the cylinder 404 extends and drives the rotating shaft 401 to rotate around the bearing bracket 7 via the rotating arm 403; the rotating shaft 401 is connected to the frame 101 of the first and second partition door housings 2, driving both to rotate to both sides along the partition door track on the pneumatic door housing 6 (gradually moving away from the center of the air duct). Auxiliary purging: During the rotation of the door, the purging assembly 5 works synchronously. The external air source is delivered to each purging branch 502 through the purging pipeline 501 to purge the ends and bottom of the partition door track, remove accumulated dust and debris, and prevent the door from getting stuck when rotating. When the door rotates to the set opening angle, the control switch triggers the cylinder 404 to stop, and the door remains open, ensuring unobstructed airflow.

[0024] III. Shutdown Process The control switch issues a closing command again, controlling cylinder 404 to reverse its action; the output shaft of cylinder 404 retracts, driving rotating shaft 401 to rotate in the opposite direction via rotating arm 403; rotating shaft 401 drives the first and second partition door housings 2 to rotate along the track towards the center, gradually approaching; the blowing assembly 5 continues to work, removing residual debris from the track to ensure smooth door closure; when the door rotates to the closed position, gate 102 forms a complete partition surface, cylinder 404 stops its action, returns to the initial closed state, and blocks the air duct again.
