Description

Technical Field

[0001] This utility model relates to the field of industrial explosion-proof technology, specifically to an explosion-proof plate based on structural reinforcement. Background Technology

[0002] In industrial production, explosion-proof panels are often used to mitigate the disaster caused by explosions. They are mainly used to quickly release the gas and pressure accumulated in the internal space during an explosion, preventing structural damage or secondary disasters. They achieve directional explosion relief through weak areas made of lightweight alloys or composite materials. They are usually installed on the top or side walls of equipment. Their core function is to balance the impact of the explosion with the structural integrity. They are a key component of industrial explosion-proof systems and are widely used in energy storage, food processing, pharmaceuticals and other fields.

[0003] Existing explosion-proof panels typically consist of thin stainless steel and an outer flange. During an explosion, when the internal shock wave and pressure reach the withstand pressure of the stainless steel plate, it will rupture to release pressure inside the exploded structure. However, although explosion-proof panels with low structural strength have the function of venting explosions, the entire explosion-proof panel needs to be replaced as a whole if it is damaged or deformed after an explosion or pressure relief, which is very wasteful. There is a lack of corresponding structures to enhance the structural strength of explosion-proof panels so that they can be reused, and improvements and optimizations are needed. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof plate based on structural reinforcement to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof plate based on structural reinforcement includes a flange, one end of which is hinged to an explosion-proof plate body, a slot is provided in one section of the explosion-proof plate body, a U-shaped stainless steel insert is inserted into the slot, one end of the explosion-proof plate body is provided with a pin groove, a locking component is inserted into the pin groove, the explosion-proof plate body includes a reinforcing steel plate, a honeycomb metal layer is provided on the inner side of the reinforcing steel plate, and thermal insulation cotton is provided on the inner side of the reinforcing steel plate.

[0006] Preferably, a sealing gasket is fixedly bonded to one end of the flange.

[0007] Preferably, one end of the U-shaped stainless steel insert plate is provided with a mounting hole, the mounting hole corresponding to the flange, and one end of the U-shaped stainless steel insert plate is provided with a locking hole.

[0008] Preferably, the explosion-proof plate body has a sealing groove in the middle, and a sealing ring is inserted into the sealing groove.

[0009] Preferably, the locking component includes a locking pin, which is inserted into a pin groove, one end of which is inserted into a locking hole, and the other end of which is fixedly connected to a connecting handle.

[0010] Preferably, one end of the connecting handle is provided with a spring groove, a spring is fixedly connected in the spring groove, and the other end of the spring is fixedly connected to the inner wall of the spring groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention proposes a structurally reinforced explosion-proof panel. The integrated explosion-proof panel consists of a central body made of reinforced steel plate, a honeycomb metal layer, and insulation cotton, and thinner U-shaped stainless steel inserts at the edges. These are securely connected by a locking mechanism. During explosion venting, the thinner U-shaped stainless steel inserts reach their pressure limit and rupture first, while the stronger explosion-proof panel body opens only through hinge rotation under impact. After the explosion is vented, the central explosion-proof panel body remains undamaged; only the U-shaped stainless steel inserts need to be replaced for reuse, thus avoiding material waste.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit 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.

[0022] Please see Figures 1-7 The present invention provides the following two preferred embodiments:

[0023] Example 1: An explosion-proof plate based on structural reinforcement includes a flange 1, with an explosion-proof plate body 2 hinged to one end of the flange 1. A slot 3 is provided in one section of the explosion-proof plate body 2, and a U-shaped stainless steel insert 4 is inserted into the slot 3. A pin groove 5 is provided in one end of the explosion-proof plate body 2, and a locking component is inserted into the pin groove 5. The explosion-proof plate body 2 includes a reinforcing steel plate 201, with a honeycomb metal layer 202 and insulation cotton 203 on the inner side of the reinforcing steel plate 201. A sealing gasket 7 is fixedly bonded to one end of the flange 1. An installation hole 8 is provided at one end of the U-shaped stainless steel insert 4, corresponding to the flange 1. A locking hole 9 is provided at one end of the U-shaped stainless steel insert 4. A sealing groove 10 is provided in the middle of the explosion-proof plate body 2, and a sealing ring 11 is inserted into the sealing groove 10.

[0024] In use, insert the U-shaped stainless steel insert 4 into the slot 3 on the outside of the explosion-proof plate body 2 and fix it with the locking assembly. Fit the sealing ring 11 into the sealing groove 10 on the outer ring of the explosion-proof plate body 2. The sealing ring 11 ensures a tight seal. The mounting holes 8 on the U-shaped stainless steel insert 4 correspond to the mounting holes on the flange 1. Adhere the sealing gasket 7 to the inside of the flange. The sealing gasket 7 improves the sealing performance of the device. Then align the flange 1 with the installation equipment or wall and fix it with bolts. At this point, the structurally reinforced explosion-proof plate is installed. The explosion-proof plate body 2 consists of an outer reinforcing steel plate 201, an inner honeycomb metal layer 202, and insulation cotton 203. The insulation cotton 203 provides insulation. 201 has strong structural strength, and the honeycomb metal layer 202 has good buffering and impact resistance. The strength of the reinforced explosion-proof plate body 2 is much higher than that of the U-shaped stainless steel insert 4 inserted on the outer ring. In the event of an explosion, the internal pressure first reaches the pressure-bearing range of the U-shaped stainless steel insert 4, causing the U-shaped stainless steel insert 4 to break first. Under the impact force, the explosion-proof plate body 2 rotates and opens through the hinge to release pressure and protect the equipment. The explosion-proof plate body 2 remains intact under the high strength of the outer reinforcing steel plate 201 and the high buffering effect of the inner honeycomb metal layer 202. After the explosion is released, it is only necessary to remove the broken U-shaped stainless steel insert 4 and reinstall the new explosion-proof plate body 2 according to the above installation method, thus avoiding the material waste of replacing the entire explosion-proof plate in the traditional way.

[0025] Example 2: Based on Example 1, the locking component includes a locking pin 601, which is inserted into a pin groove 5. One end of the locking pin 601 is inserted into a locking hole 9, and the other end of the locking pin 601 is fixedly connected to a connecting handle 602. One end of the connecting handle 602 is provided with a spring groove 603, and a spring 604 is fixedly connected inside the spring groove 603. The other end of the spring 604 is fixedly connected to the inner wall of the spring groove 603.

[0026] During use, when the U-shaped stainless steel insert 4 is inserted into the slot 3 outside the explosion-proof plate body 2 during installation, the U-shaped stainless steel insert 4 sequentially presses the locking pins 601 on the locking assembly. After insertion, the locking pins 601 are aligned with the corresponding locking holes 9 on the U-shaped stainless steel insert 4. Under the restoring compression action of the spring 604 on the spring groove 603 of the connecting handle 602, they are inserted into the locking holes 9, thus completing the insertion and fixing of the U-shaped stainless steel insert 4 and the explosion-proof plate body 2. After the explosion is vented, the bolts on the flange 1 are removed, and the connecting handles 602 on multiple sets of locking assemblies are pulled. The connecting handles 602 simultaneously drive multiple sets of locking pins 601 to disengage from the locking holes 9, and the broken U-shaped stainless steel insert 4 can be removed from the bottom and replaced.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
