Description

Technical Field

[0001] This application relates to the field of ventilation and explosion relief technology, and in particular to a ventilation and explosion relief device. Background Technology

[0002] In industrial production and storage processes, especially in enclosed work spaces where there is a risk of flammable, explosive, or harmful gas escape, safe pressure relief and efficient ventilation are core elements for ensuring production safety. Such locations have extremely stringent safety requirements, making the installation of ventilation windows a crucial measure to achieve both ventilation and pressure relief. Ventilation windows effectively promote airflow within enclosed spaces, rapidly reducing the concentration of flammable materials, effectively preventing explosions that may be caused by gas accumulation, and significantly enhancing the overall safety of the site.

[0003] To meet increasingly stringent automation standards, most mainstream ventilation and explosion relief devices currently employ electric or pneumatic actuators to precisely control the opening and closing of ventilation windows. However, it is important to note that traditional ventilation and explosion relief devices are normally closed, and the drive components controlling the opening and closing of the windows cannot achieve rapid opening. In the event of a risk of flammable, explosive, or harmful gas escape from the enclosed work space, or even an explosion, the existing drive components cannot guarantee that the windows will open quickly to achieve ventilation and pressure relief, posing a significant safety hazard to the enclosed work space. Utility Model Content

[0004] In order to enable the window sash to open quickly and ensure rapid ventilation and pressure relief in the event of an explosion, this application provides a ventilation and explosion relief device.

[0005] The ventilation and explosion relief device provided in this application adopts the following technical solution:

[0006] A ventilation and explosion relief device includes a frame for installation on a target device, a ventilation opening for ventilation and pressure relief on the frame, a baffle for blocking the ventilation opening movably disposed on the frame, a control component for controlling the opening and closing of the baffle on the frame, an explosion relief port on the baffle, an explosion relief plate installed on the explosion relief port on the baffle, the explosion relief plate sealing the explosion relief port, and the explosion relief plate being able to open and relieve pressure when the pressure difference on both sides reaches a preset value.

[0007] By adopting the above technical solution, the frame is installed on the target device. The ventilation openings on the frame provide ventilation, and the movable baffles can block and seal the ventilation openings. The control components can control the opening and closing of the baffles, achieving flexible control of the ventilation openings to meet different ventilation needs. The explosion vents and explosion vents installed on the baffles can open to release pressure when the pressure difference between the two sides reaches a preset value. When the target device explodes, the internal pressure rises sharply. Under the action of the internal and external pressure difference, the explosion vents open, and the pressure is quickly released through the explosion vents, reducing the deformation and component damage caused by the explosion of the target device, and thus helping to improve the service life of the target device.

[0008] Optionally, the control component includes an electric push rod disposed between the frame and the baffle, wherein the extension and retraction of the moving part of the electric push rod can cause the baffle to flip so as to control the opening and closing of the vent.

[0009] By adopting the above technical solution, the control component uses an electric push rod. The moving part of the electric push rod extends and retracts, causing the baffle to flip, thereby controlling the opening and closing of the ventilation opening. This design makes the opening and closing control of the baffle more precise and highly automated, facilitating accurate adjustment according to actual ventilation needs, and improving the intelligence and ease of operation of the device.

[0010] Optionally, the electric push rod is fixedly connected to the frame, and a connecting rod is hinged to the moving part of the electric push rod, the connecting rod being hinged to the baffle.

[0011] By adopting the above technical solution, the electric push rod is fixedly connected to the frame, and its moving part is connected to the baffle through the push rod. This structure converts the linear motion of the electric push rod into the flipping motion of the baffle through the transmission action of the push rod, realizing effective control of the opening and closing of the baffle. Moreover, the structure is simple and reliable, and can stably drive the baffle to move, ensuring the smooth opening and closing of the ventilation opening.

[0012] Optionally, an elastic element is provided between the frame and the baffle, the elastic element being used to push the baffle toward an open state.

[0013] By adopting the above technical solution, an elastic element is installed between the frame and the baffle. The elastic element pushes the baffle towards the open state. This allows the electric push rod to open the baffle with the assistance of the elastic element, reducing the load on the electric push rod.

[0014] Optionally, a latch is provided between the baffle and the frame to improve the sealing effect of the baffle on the frame.

[0015] By adopting the above technical solution, a locking mechanism is installed between the baffle and the frame, which improves the sealing effect of the baffle on the frame. Under normal ventilation or when explosion venting is not required, the locking mechanism ensures that the baffle and the frame fit tightly, preventing leakage of gas, dust, etc., ensuring the sealing performance of the device, and maintaining the stability of the internal environment of the target device.

[0016] Optionally, the latch includes an electronic lock and a limiting buckle for cooperating with the electronic lock. The electronic lock is fixedly connected to one of the two components, the frame and the baffle, and the limiting buckle is fixedly connected to the other component.

[0017] By adopting the above technical solution, the latch uses an electronic lock and a corresponding limit buckle. The electronic lock is fixedly connected to one component of the frame or baffle, and the limit buckle is fixedly connected to another component. This electronic lock design allows the opening and closing of the latch to be controlled by electronic signals, improving the automation and intelligence level of the device, facilitating remote operation and centralized management, while also enhancing the security and reliability of the latch, ensuring that the baffle can be reliably locked when needed, and guaranteeing the normal operation and safety performance of the device.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The explosion vent and explosion vent plate installed on the baffle plate cause the internal pressure to rise sharply when the target device explodes. Under the action of the internal and external pressure difference, the explosion vent plate tears open and quickly releases pressure through the explosion vent, reducing the deformation and component damage caused by the explosion of the target device, which helps to improve the service life of the target device.

[0020] 2. An elastic element is installed between the frame and the baffle. The elastic element pushes the baffle towards the open state. This reduces the load on the electric push rod by assisting in the opening process of the baffle. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. Example 1

[0030] This application discloses a ventilation and explosion relief device. For example... Figure 1 , Figure 2 as well as Figure 3 The ventilation and explosion relief device includes a frame 1 mounted on the target device. The frame 1 has a ventilation opening 11 for depressurizing or ventilating the target device. A baffle 12 is movably mounted on the frame 1, and the baffle 12 can be flipped to control the opening and closing of the ventilation opening 11. The baffle 12 can be slidably mounted on the frame 1 or flipped onto the frame 1. In this embodiment, the baffle 12 is hinged to the outer wall of the frame 1 via a hinge or pivot. A control component 2 for controlling the opening and closing of the baffle 12 is provided on the frame 1.

[0031] The baffle 12 has an explosion vent 13, and an explosion vent plate 14 is installed on the baffle 12. The explosion vent plate 14 is used to seal the explosion vent 13. The explosion vent plate 14 typically includes an explosion vent membrane, which is installed on the baffle 12 via threaded fittings. When the baffle 12 closes the ventilation opening 11, if an explosion occurs inside the target device, the internal pressure of the target device rises sharply. Under the action of the internal and external pressure difference, the explosion vent membrane is torn, thereby causing the explosion vent 13 to open rapidly, achieving a rapid pressure relief effect. This method can effectively reduce the deformation of the side wall of the target device or damage to other components, which is beneficial to improving the service life of the target device. In addition, by combining the baffle 12 and the explosion vent plate 14, the space required for the separate installation of the baffle 12 and the explosion vent plate 14 is reduced, which is beneficial to improving the space utilization rate of the target device.

[0032] The control component 2 can be an electric push rod 21, a motor, or a cylinder, etc. In this embodiment, the control component 2 includes an electric push rod 21 disposed between the frame 1 and the baffle 12. The electric push rod 21 directly or indirectly pushes the baffle 12 to flip. A controller for controlling the extension and retraction of the electric push rod 21 is provided in the target device. The operator can remotely connect to the controller to control the extension and retraction of the electric push rod 21, thereby controlling the opening and closing of the baffle 12. Temperature sensors, smoke concentration sensors, or combustible gas concentration sensors can be installed in the target device. The sensors are electrically connected to the controller. When the sensors detect that the temperature, smoke concentration, or combustible gas concentration in the target device reaches a preset value, the corresponding sensors send an electrical signal to the controller. After receiving the electrical signal, the controller controls the electric push rod 21 to drive the baffle 12 to open.

[0033] In this embodiment, the electric push rod 21 directly pushes the baffle 12 to flip. The electric push rod 21 is hinged to the inner wall of the frame 1, and the piston rod of the electric push rod 21 is hinged to the baffle 12. By controlling the extension and retraction of the piston rod of the electric push rod 21, the baffle 12 can be flipped, so that the operator can remotely control the flipping of the baffle 12 and remotely control the opening and closing of the ventilation opening 11.

[0034] A latch 4 is provided between the frame 1 and the baffle 12 to maintain the closed and locked state of the baffle 12 when it is closed. The latch 4 includes an electronic lock 41 fixedly connected to the frame 1, and a limiting buckle 42 provided on the baffle 12 to cooperate with the electronic lock 41. When the baffle 12 is closed to seal the explosion vent 13, the limiting buckle 42 flips with the baffle 12 to engage with the electronic lock 41, thereby achieving the locking effect of the baffle 12. The operator can remotely control the electronic lock 41 to open, thereby achieving the effect of remotely unlocking the baffle 12. In addition, the latch 4 and the limiting buckle 42 cooperate to resist impact loads, and can ensure the pressure difference on both sides of the explosion vent membrane at the moment of explosion in the event of thermal runaway, ensuring that the explosion vent membrane can open smoothly and achieve the effect of timely pressure relief. Example 2

[0035] like Figure 4 In this embodiment, all other aspects are the same as in Embodiment 1, except that in other embodiments, the electric push rod 21 indirectly pushes the baffle 12 to flip. The electric push rod 21 is fixedly connected to the inner wall of the frame 1, and a slider 22 is fixedly connected to the piston rod of the electric push rod 21. The slider 22 is slidably disposed on the inner wall of the frame 1, and a connecting rod 23 is hinged to the slider 22. The end of the connecting rod 23 away from the electric push rod 21 is hinged to the baffle 12. The operator controls the extension and retraction of the piston rod of the electric push rod 21 to drive the slider 22 to slide, thereby driving the connecting rod 23 to rotate, so as to control the flipping of the baffle 12 and drive the vent 11 to open and close. Example 3

[0036] like Figure 5 and Figure 6 In this embodiment, all other aspects are the same as in Embodiment 1, except that an elastic element 3 is provided between the frame 1 and the baffle 12. The elastic element 3 is used to push the baffle 12 to rotate away from the vent 11. The elastic element 3 can be a pneumatic spring 31 or a spring telescopic rod, etc. In this embodiment, the elastic element 3 is a pneumatic spring 31 provided between the frame 1 and the baffle 12. One end of the pneumatic spring 31 is hinged to the inner wall of the frame 1, and the other end of the pneumatic spring 31 is hinged to the baffle 12. The pneumatic spring 31 is provided to assist the baffle 12 in opening and reduce the load borne by the electric push rod 21 when pushing the baffle 12 to open. Example 4

[0037] like Figure 7 In this embodiment, all other aspects are the same as in embodiment 1, except that the elastic element 3 includes a slide block 32 that is slidably disposed on the inner wall of the frame 1. A support rod 34 is hinged to the slide block 32. The end of the support rod 34 away from the slide block 32 is hinged to the baffle 12. A tension spring 33 is provided between the slide block 32 and the frame 1. The tension spring 33 drives the slide block 32 to move. Under the linkage action of the support rod 34, the baffle 12 can be pushed towards the open state.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
