[0002] Currently, the external structure of pneumatic slide gates consists of a slide gate body, a drive chamber, a push-pull lever, and a drive cylinder. Installing this type of pneumatic slide gate on general air ducts can meet the requirements for controlling the medium. However, if this conventional structure of a pneumatic slide gate is installed on a dust duct, although it can meet the control requirements, the lack of a cover in the drive chamber of the pneumatic slide gate, due to the presence of dust particles in the medium, allows these particles to leak out, impacting the surrounding environment. Furthermore, the opening and closing status of the pneumatic slide gate is difficult to monitor.

[0003] Therefore, how to effectively monitor the opening and closing status of pneumatic slide gates has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0041] See Figure 1-2 As shown, this embodiment provides an improved pneumatic slide gate, including: a slide gate body 100; a housing, formed in the middle of the slide gate body 100; a cover plate 120, covering the housing; a push-pull assembly, located inside the housing; a drive assembly, located on one side of the housing, with one end of the drive assembly near the housing connected to the push-pull assembly; a plug-in assembly, located at the end of the push-pull assembly away from the drive assembly; a channel 150, formed on the side of the slide gate body 100 away from the drive assembly; a fixing assembly, having a plurality of fixing assemblies, the plurality of fixing assemblies passing through the housing and the cover plate 120; a first magnetic proximity switch 171, located at the end of the cover plate 120 near the drive assembly, and the first magnetic proximity switch 171 is arranged on one side of the cover plate 120 in a direction parallel to the axis of the slide gate body 100; a second magnetic proximity switch 172, located at the end of the cover plate 120 away from the drive assembly, and the second magnetic proximity switch 172 and the first magnetic proximity switch 171 are located on the same side.

[0042] As can be seen, the housing, cover plate 120, push-pull assembly, drive assembly, plug-in assembly, and fixing assembly together constitute the main structure of the pneumatic slide gate provided in this embodiment. The drive assembly drives the push-pull assembly, allowing the plug-in assembly to dock or separate well with the channel 150, thereby realizing the opening and closing function of the pneumatic slide gate. The cover plate 120 prevents dust particles in the medium from leaking out, minimizing the impact on the surrounding environment. Furthermore, this embodiment uses a first magnetic proximity switch 171 and a second magnetic proximity switch 172 to achieve accurate monitoring and control of the working status of the pneumatic slide gate.

[0043] Specifically, the housing includes: a first housing and a second housing, the second housing being sleeved on the outside of the first housing, the first housing having a first cavity 111 inside, and the second housing having a second cavity 112 inside.

[0044] As can be seen, the housing includes a first cavity 111 and a second cavity 112. The first cavity 111 is mainly used to install the push-pull assembly and the drive assembly, ensuring that they can work smoothly without being disturbed by the external environment. The second cavity 112 serves as a protective layer, further reinforcing the structure of the entire pneumatic slide gate, enabling it to maintain a stable working state even in various complex environments.

[0045] Specifically, the push-pull assembly includes a push-pull lever 131, which is parallel to the length direction of the first cavity 111 and is disposed inside the first cavity 111.

[0046] Specifically, the plug-in assembly includes: a plug-in plate 151, disposed at the end of the push-pull lever 131 away from the drive assembly; and plug-in slots, which are formed on both sides of the channel 150 along the axial direction of the channel 150, with the plug-in plate 151 matching the plug-in slots.

[0047] As can be seen, the push-pull lever 131 can perform a stable push-pull action along the length direction of the first cavity 111, which is the key to realizing the docking or separation of the plug plate 151 and the channel 150. One end of the push-pull lever 131 is tightly connected to the drive component to ensure the accuracy and efficiency of power transmission, while the other end is connected to the plug plate 151. Through the reciprocating motion of the push-pull lever 131, the plug plate 151 can accurately insert or exit the plug slot, thereby realizing the opening and closing function of the pneumatic plug-in door.

[0048] Specifically, the drive assembly includes: a cylinder base 141, which is fixedly connected to the end of the first housing away from the insertion slot; and a drive cylinder 142, which is arranged in a direction parallel to the axis of the push-pull rod 131, with one end of the drive cylinder 142 near the cavity extending out of the base and connected to the push-pull rod 131.

[0049] Specifically, the fixing component includes: cover plate bolts 161, of which there are a plurality of cover plate bolts 161 passing through the cover plate 120 and being fixed to the housing, and the cover plate bolts 161 are evenly arranged along the circumferential direction of the cover plate 120.

[0050] As can be seen, the drive cylinder 142, securely connected to the cylinder base 141, ensures that it will not wobble or shift during operation. The cover plate bolts 161 ensure a tight fit and secure connection between the cover plate 120 and the housing, further enhancing the structural strength and sealing performance of the entire pneumatic slide gate. This allows the pneumatic slide gate to maintain structural stability and reliability during operation, regardless of internal air pressure changes or external impact forces.

[0051] Specifically, the improved pneumatic slide gate also includes a controller, which is located outside the slide gate body 100 and is connected to a first magnetic proximity switch 171 and a second magnetic proximity switch 172.

[0052] Specifically, the improved pneumatic slide gate also includes an alarm, which is located on the outside of the slide gate body 100 and is connected to the controller.

[0053] As can be seen, the controller receives real-time signals from the first magnetic proximity switch 171 and the second magnetic proximity switch 172, and processes these signals according to a preset logic algorithm to achieve precise control of the pneumatic slide gate's operating state. When the insertion assembly is fully connected to or completely separated from the channel 150, the corresponding magnetic proximity switch triggers a signal. The controller then determines the current state of the pneumatic slide gate based on these signals and adjusts the operating state of the drive assembly accordingly to ensure the accurate opening or closing of the slide gate. The alarm, as a safety warning device, is closely connected to the controller. When the controller detects an abnormal signal, such as the slide gate failing to complete the opening or closing action within a predetermined time, or the state fed back by the magnetic proximity switch not matching expectations, the controller immediately activates the alarm, issuing an audible and visual alarm to alert the operator and prompt them to take appropriate measures. This greatly enhances the safety performance of the pneumatic slide gate and effectively avoids safety accidents that may be caused by equipment failure or operational errors.

[0054] Specifically, the longitudinal cross-sectional area of ​​the plug-in board 151 is larger than the longitudinal cross-sectional area of ​​the channel 150.

[0055] It can be seen that the cross-sectional area of ​​the plug plate 151 is slightly larger than that of the channel 150. This not only ensures that the plug plate 151 can form a tight and stable connection when inserted into the channel 150, effectively preventing leakage problems caused by airflow or medium pressure, but also improves the overall sealing and reliability of the plug plate door.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
