Description

Technical Field

[0001] This utility model relates to the field of polyethylene dust protection, and in particular to a protective shell for suppressing polyethylene dust explosions. Background Technology

[0002] Polyethylene dust is prone to explosion during production, transportation, and storage due to friction, static electricity, or localized high temperature. The explosion pressure can reach tens of MPa and is accompanied by the spread of high-temperature flames. A protective shell is needed to form a physical barrier to contain the explosion.

[0003] The protective housing is usually equipped with an explosion-proof valve as a key component for pressure relief and flame isolation. The sealing reliability and spring triggering performance of the explosion-proof valve directly affect the protection effect.

[0004] Most existing explosion-proof valves are closed structures, requiring complete disassembly for maintenance to inspect critical conditions such as sealing surface wear, spring fatigue, and valve core jamming. Polyethylene dust is sticky and easily accumulates inside the explosion-proof valve and adheres to the surface of components, accelerating seal failure and mechanical jamming. Frequent disassembly not only prolongs production downtime but may also cause secondary safety risks due to dust leakage during disassembly and assembly.

[0005] Therefore, it is necessary to provide a protective casing for suppressing polyethylene dust explosions to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] Given that the existing technology includes explosion-proof valves with polyethylene dust explosion protective shells, which lack a visual maintenance structure and require disassembly to inspect the condition of key components such as internal sealing surfaces and springs, there are problems such as low maintenance efficiency, long downtime, and the risk of dust leakage during disassembly and assembly.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A protective housing for suppressing polyethylene dust explosions, comprising: The explosion-proof valve body consists of an observation plate, two fixing components, and multiple limit components. The observation plate is disposed on the surface of the explosion-proof valve body; The two fixing components are respectively disposed between the observation plate and the explosion-proof valve body. The fixing components include a U-shaped fixing block and a rectangular block. The U-shaped fixing block is connected to the surface of the explosion-proof valve body, and the rectangular block is disposed inside the U-shaped fixing block and adjacent to the side of the observation plate. Multiple limiting components are respectively disposed between the observation plate and the explosion-proof valve body.

[0009] As a further improvement of this utility model, a fixing bolt is provided between the rectangular block and the U-shaped fixing block.

[0010] As a further embodiment of this utility model: the U-shaped fixing block and the rectangular block are used for positioning the observation plate during installation, and a fixing hole adapted to the fixing bolt is provided between the U-shaped fixing block and the rectangular block.

[0011] As a further improvement of this utility model: the observation plate is made of transparent material, and the observation plate is used to view the internal components of the explosion-proof valve body.

[0012] As a further embodiment of this utility model: the limiting component includes a fixed seat, a fixed rod, a movable sleeve and a limiting frame, the fixed seat is connected to the surface of the explosion-proof valve body, and the fixed rod is connected to the surface of the fixed seat.

[0013] As a further embodiment of this utility model: the movable sleeve is fitted onto the surface of the fixed rod, the limiting frame is connected to the movable sleeve through a connecting block, and a limiting bolt is provided between the movable sleeve and the fixed rod.

[0014] As a further improvement of this utility model, a stop block is connected to the top of the fixing rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a protective shell for suppressing polyethylene dust explosions. By setting an observation plate made of transparent material, the condition of key components such as the sealing surface and spring inside the explosion-proof valve body can be directly observed. Inspection can be completed without disassembling the entire explosion-proof valve, solving the problem that existing closed structures require disassembly for inspection, improving maintenance efficiency and reducing production downtime. With the cooperation of U-shaped fixing blocks, rectangular blocks and fixing bolts, the observation plate and the explosion-proof valve body can be quickly positioned and fixed, making installation and disassembly convenient. This avoids the risk of polyethylene dust leakage caused by the complete disassembly of the explosion-proof valve and reduces secondary safety hazards.

[0016] 2. The fixed base, fixed rod, movable sleeve, limit frame, and limit bolt can form a stable limit on the observation plate, enhancing its structural stability after installation. This ensures that the observation plate is not easily loosened under conditions such as polyethylene dust adhesion and vibration, guaranteeing the continuous effectiveness of visual maintenance. The stop block at the top of the fixed rod prevents the movable sleeve from falling off the fixed rod, further improving the structural reliability of the limit assembly, indirectly ensuring the stability of the observation plate, and extending the service life of the equipment.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1

[0023] Please see Figure 1 - Figure 5 This is the first embodiment of the present invention. This embodiment provides a protective housing for suppressing polyethylene dust explosions, comprising: The explosion-proof valve consists of: 1. a main body; 2. an observation plate; 3. two fixing components; and 4. multiple limit components. The observation plate 2 is installed on the surface of the explosion-proof valve body 1; Two fixing components 3 are respectively disposed between the observation plate 2 and the explosion-proof valve body 1. The fixing component 3 includes a U-shaped fixing block 31 and a rectangular block 32. The U-shaped fixing block 31 is connected to the surface of the explosion-proof valve body 1, and the rectangular block 32 is disposed inside the U-shaped fixing block 31 and is adjacent to the side of the observation plate 2. Multiple limit components 4 are respectively disposed between the observation plate 2 and the explosion-proof valve body 1.

[0024] A fixing bolt 33 is provided between the rectangular block 32 and the U-shaped fixing block 31.

[0025] The U-shaped fixing block 31 and the rectangular block 32 are used for positioning the observation plate 2 during installation. Fixing holes adapted to the fixing bolt 33 are provided between the U-shaped fixing block 31 and the rectangular block 32.

[0026] The observation panel 2 is made of transparent material and is used to view the internal components of the explosion-proof valve body 1.

[0027] The limiting component 4 includes a fixed base 41, a fixed rod 42, a movable sleeve 43, and a limiting frame 44. The fixed base 41 is connected to the surface of the explosion-proof valve body 1, and the fixed rod 42 is connected to the surface of the fixed base 41.

[0028] The movable sleeve 43 is fitted onto the surface of the fixed rod 42. The limiting frame 44 is connected to the movable sleeve 43 through a connecting block. A limiting bolt 45 is provided between the movable sleeve 43 and the fixed rod 42.

[0029] A stop 5 is connected to the top of the fixing rod 42.

[0030] Example 2

[0031] Please see Figure 1 - Figure 5 This is the second embodiment of the present utility model.

[0032] For example, the explosion-proof valve body 1 normally performs the functions of pressure relief and flame isolation, resisting the high pressure and high temperature generated by the polyethylene dust explosion; the transparent observation plate 2 maintains a visual channel to the inside of the explosion-proof valve body 1, and the staff can directly monitor the status of sealing surface wear, spring fatigue, valve core jamming and dust accumulation in real time through the observation plate 2 without disassembling the explosion-proof valve.

[0033] The limiting frame 44 adopts an L-shaped structure, and a high-temperature resistant silicone pad is pasted on the contact part with the observation plate 2. This not only avoids scratches on the observation plate 2 caused by direct metal contact, but also compensates for the slight deformation of the observation plate 2 caused by temperature changes through the elastic deformation of the silicone, ensuring a tight fit.

[0034] The observation panel 2 is made of high-temperature resistant transparent polycarbonate or borosilicate glass, which not only meets the impact resistance requirements in the polyethylene dust explosion environment, but also ensures light transmittance, so as to ensure clear observation of internal components.

[0035] The edges of the observation plate 2 are rounded, and the connection with the rectangular block 32 adopts an embedded structure (the side of the observation plate 2 is provided with a slot, and the corresponding position of the rectangular block 32 is provided with a protrusion), which further improves the connection strength between the two and avoids the observation plate 2 from cracking at the edges under the pressure of the limiting component 4.

[0036] The fixing component 3 first completes the positioning of the observation plate 2: a U-shaped fixing block 31 is preset on the surface of the explosion-proof valve body 1, and a rectangular block 32 is fixed on the side of the observation plate 2. During installation, the rectangular block 32 is embedded into the groove of the U-shaped fixing block 31. The limiting characteristics of the U-shaped structure are used to achieve precise alignment between the observation plate 2 and the explosion-proof valve body 1. Then, the fixing bolt 33 passes through the matching fixing holes of the U-shaped fixing block 31 and the rectangular block 32, and is tightened to complete the initial fixing of the observation plate 2.

[0037] The limiting component 4 further enhances the stability of the fixation: the fixed base 41 vertically fixes the fixed rod 42 to the surface of the explosion-proof valve body 1, and the movable sleeve 43 slides along the fixed rod 42 to the position that fits the edge of the observation plate 2, driving the limiting frame 44 to press the surface of the observation plate 2; tightening the limiting bolt 45 makes the movable sleeve 43 and the fixed rod 42 rigidly locked, forming a multi-directional limit, preventing the observation plate from being displaced due to vibration or explosion impact, and the stop 5 at the top of the fixed rod 42 prevents the movable sleeve 43 from falling off the fixed rod 42 during adjustment or vibration, ensuring the structural integrity of the limiting component 4.
