Description

Technical Field

[0001] This utility model relates to the field of explosion relief plate technology, and more specifically, to a rock wool core material structure for explosion relief plates used in the petrochemical industry. Background Technology

[0002] In the petrochemical industry, the presence of flammable and explosive substances poses a high risk of explosion. Explosion-venting rock wool core structures serve as an important safety protection device, capable of releasing pressure in a timely manner during an explosion, reducing the harm to buildings and personnel. Explosion-venting rock wool core structures typically consist of an external explosion-venting plate, an explosion-proof pressure-relieving keel, a rock wool layer, and an internal explosion-venting plate.

[0003] In existing explosion-proof rock wool core material structures, the explosion-proof pressure relief keel usually serves to support and transmit pressure. However, because the explosion-proof pressure relief keel is usually a straight structure, and the elastic deformation space of such a straight structure is limited, its ability to withstand explosion pressure, buffer performance, and pressure relief performance are relatively poor. As a result, the overall explosion-proof protection effect of the explosion-proof rock wool core material structure is poor. In view of this, we propose an explosion-proof rock wool core material structure for the petrochemical industry. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rock wool core material structure for explosion relief panels used in the petrochemical industry, so as to solve the technical problem that the explosion relief protection effect of the current rock wool core material structure is poor.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rock wool core material structure for explosion relief plates used in the petrochemical industry, comprising an outer explosion relief plate, an inner explosion relief plate, an explosion-proof pressure relief keel, and a rock wool layer. The inner explosion relief plate is connected and fixed to the outer explosion relief plate through the explosion-proof pressure relief keel. The rock wool layer is arranged between the outer explosion relief plate and the inner explosion relief plate. The explosion-proof pressure relief keel is wavy. Pressure relief channels are formed between the outer explosion relief plate and the explosion-proof pressure relief keel, and between the inner explosion relief plate and the explosion-proof pressure relief keel.

[0006] The external and internal explosion venting plates are each equidistantly arranged with several sets of connecting rods on opposite sides, and the connecting rods are respectively connected to the crests before and after the explosion-proof pressure relief keel. The surface of the explosion-proof pressure relief keel is provided with several sets of guide grooves at equal intervals.

[0007] In this invention, the explosion-proof pressure relief keel is wavy. Therefore, after the explosion-proof pressure relief keel is connected to the external and internal explosion relief plates, pressure relief channels are reserved at equal intervals between them. Thus, when the explosion-proof pressure relief keel is subjected to explosion pressure, the crests and troughs of the waves will bend and compress, effectively buffering the pressure and reducing damage to the overall structure. Furthermore, during pressure relief, the wavy shape of the explosion-proof pressure relief keel can guide airflow more evenly. Due to the undulation of the waves, the airflow is dispersed into multiple directions when passing through the gaps in the explosion-proof pressure relief keel, avoiding uneven pressure relief caused by localized airflow concentration, thereby improving the pressure relief effect and greatly ensuring the structural integrity of the structure. The invention improves the explosion-proof protection effect by arranging several sets of connecting rods between the explosion-proof pressure relief keels, and then combining the connecting rods with the explosion-proof pressure relief keels to form an integral structure. This achieves the overall positioning effect of each explosion-proof pressure relief keel, preventing the individual explosion-proof pressure relief keel from shifting when subjected to explosion pressure, thus affecting the explosion-proof protection effect. Furthermore, a guide groove is set on the surface of the explosion-proof pressure relief keel. The guide groove has a trapezoidal cross-section, wider at the top and narrower at the bottom. When the explosion gas passes through the gaps between the explosion-proof pressure relief keels, the guide groove can guide the airflow to flow more orderly, further improving the airflow dispersion effect and preventing the airflow from forming turbulence in local areas.

[0008] Preferably, the explosion-proof pressure relief keel has a rectangular hole at the top, and the rock wool layer penetrates the rectangular hole.

[0009] Preferably, the crests before and after the explosion-proof pressure relief keel are provided with connecting screw holes, and the connecting rod is provided with connecting bolts corresponding to the connecting screw holes.

[0010] Preferably, the connecting rod includes a triangular strip plate, the triangular strip plate having an arc-shaped groove arranged on the side facing the explosion-proof pressure relief keel, and the arc-shaped groove fitting with the crest of the explosion-proof pressure relief keel, and the side of the triangular strip plate facing away from the arc-shaped groove fitting with the corresponding external or internal explosion relief plate.

[0011] Preferably, a T-shaped plate is arranged on the side of the triangular strip plate facing away from the arc groove, and several sets of T-shaped grooves are equally spaced on the opposite sides of the external and internal explosion venting plates, and the T-shaped plate is inserted into the T-shaped groove. Welding blocks are arranged at both ends of the two sides of the triangular strip plate, and fixing bolts are arranged on the welding blocks.

[0012] Preferably, the cross-section of the guide channel is trapezoidal, and the guide channel is wider at the top and narrower at the bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the explosion-proof pressure relief keel is wavy. Therefore, after the explosion-proof pressure relief keel is connected to the outer and inner explosion relief plates, pressure relief channels are reserved at equal intervals between them. Thus, when the explosion-proof pressure relief keel is subjected to explosion pressure, the crests and troughs of the waves will bend and compress, thereby effectively buffering the pressure and reducing damage to the overall structure. Furthermore, during the pressure relief process, the wavy explosion-proof pressure relief keel can guide the airflow to pass through more evenly. Due to the undulation of the waves, the airflow will be dispersed into multiple directions when passing through the gaps in the explosion-proof pressure relief keel, avoiding uneven pressure relief caused by local airflow concentration, thereby improving the pressure relief effect. This can greatly ensure the explosion relief protection effect of the structure and solve the technical problem of poor explosion relief protection effect of the current explosion relief plate rock wool core material structure. Therefore, this utility model has the advantage of better explosion relief protection.

[0015] 2. This utility model also arranges several sets of connecting rods between the explosion-proof pressure relief keels, and then combines the connecting rods with the explosion-proof pressure relief keels to form an integral structure, thereby achieving the overall positioning effect of each explosion-proof pressure relief keel. This avoids the phenomenon of a single explosion-proof pressure relief keel being misaligned when it is subjected to explosion pressure, thus affecting the explosion relief protection effect. Furthermore, a guide groove is set on the surface of the explosion-proof pressure relief keel. The guide groove has a trapezoidal cross-section, which is wider at the top and narrower at the bottom. When the explosion gas flows through the gap of the explosion-proof pressure relief keel, the guide groove can guide the airflow to flow more orderly, further improving the airflow dispersion effect and preventing the airflow from forming turbulence in local areas.

[0024] like Figures 1 to 6 As shown, this utility model relates to a rock wool core material structure for explosion relief panels used in the petrochemical industry, including an outer explosion relief panel 1, an inner explosion relief panel 2, an explosion-proof pressure relief keel 3, and a rock wool layer 4. The inner explosion relief panel 2 is connected and fixed to the outer explosion relief panel 1 through the explosion-proof pressure relief keel 3. The rock wool layer 4 is arranged between the outer explosion relief panel 1 and the inner explosion relief panel 2. The explosion-proof pressure relief keel 3 is wavy, and pressure relief channels are formed between the outer explosion relief panel 1 and the explosion-proof pressure relief keel 3, and between the inner explosion relief panel 2 and the explosion-proof pressure relief keel 3. A rectangular hole 301 is opened at the top of the explosion-proof pressure relief keel 3, and the rock wool layer 4 passes through the rectangular hole 301.

[0025] The explosion relief structure, consisting of an external explosion relief plate 1, an internal explosion relief plate 2, an explosion-proof pressure relief keel 3, and a rock wool layer 4, is installed in chemical production environments to provide explosion pressure relief protection. When subjected to explosion pressure, the wave crests and troughs of the explosion-proof pressure relief keel 3 bend and compress, effectively buffering the pressure and reducing damage to the overall structure. Furthermore, during the pressure relief process, the wave-shaped explosion-proof pressure relief keel 3 can guide the airflow more evenly through the pressure relief channel. Due to the undulation of the waves, the airflow is dispersed into multiple directions when passing through the gaps in the explosion-proof pressure relief keel 3, avoiding uneven pressure relief caused by localized airflow concentration, thereby improving the pressure relief effect and greatly ensuring the explosion protection effect of the structure.

[0026] In the embodiments of this utility model, several sets of connecting rods 6 are equidistantly arranged on opposite sides of the external explosion relief plate 1 and the internal explosion relief plate 2, and the connecting rods 6 are respectively connected to the front and rear crests of the explosion-proof pressure relief keel 3. Several sets of guide grooves 302 are equidistantly opened on the surface of the explosion-proof pressure relief keel 3; the cross section of the guide groove 302 is trapezoidal, and the guide groove 302 is wider at the top and narrower at the bottom.

[0027] The connecting rod 6 and the explosion-proof pressure relief keel 3 are combined to form an integral structure, thereby achieving the overall positioning effect of each explosion-proof pressure relief keel 3. This prevents the explosion-proof pressure relief keel 3 from being misaligned when it is subjected to explosion pressure, thus affecting the explosion relief protection effect. When the explosion gas flows through the gap of the explosion-proof pressure relief keel 3, the trapezoidal guide groove 302, which is wider at the top and narrower at the bottom, can guide the airflow to flow more orderly, further improving the airflow dispersion effect and preventing the airflow from forming turbulence in local areas.

[0028] Specifically, the front and rear crests of the explosion-proof pressure relief keel 3 are provided with connecting screw holes 303, and the connecting rod 6 is provided with connecting bolts 604 corresponding to the connecting screw holes 303; when connecting the connecting rod 6 and the explosion-proof pressure relief keel 3, the connecting rod 6 is directly attached to the crest of the explosion-proof pressure relief keel 3, and then the connecting bolts 604 are screwed into the connecting screw holes 303, thereby realizing the connection and fixation between the connecting rod 6 and the explosion-proof pressure relief keel 3.

[0029] Furthermore, the connecting rod 6 includes a triangular strip 601. The triangular strip 601 has an arc-shaped groove 602 on the side facing the explosion-proof pressure relief keel 3, and the arc-shaped groove 602 fits into the crest of the explosion-proof pressure relief keel 3. The side of the triangular strip 601 facing away from the arc-shaped groove 602 fits into the corresponding external explosion relief plate 1 or internal explosion relief plate 2. The arc-shaped groove 602 of the triangular strip 601 can match and connect with the crest of the explosion-proof pressure relief keel 3, and the triangular strip 601 can fit and connect with the external explosion relief plate 1 or internal explosion relief plate 2 over a large area, thereby greatly improving the stability of the connection and conduction between the connecting rod 6 and the explosion-proof pressure relief keel 3.

[0030] Furthermore, a T-shaped plate 603 is arranged on the side of the triangular strip 601 facing away from the arc-shaped groove 602. Several sets of T-shaped grooves 5 are equidistantly opened on the opposite sides of the external explosion venting plate 1 and the internal explosion venting plate 2, and the T-shaped plate 603 is inserted into the T-shaped groove 5. Welding blocks 605 are arranged at both ends of the two sides of the triangular strip 601, and fixing bolts 606 are arranged on the welding blocks 605. When the connecting rod 6 is installed with the external explosion venting plate 1 and the internal explosion venting plate 2, the T-shaped plate 603 is inserted into the T-shaped groove 5, and then the fixing bolts 606 are screwed into the corresponding external explosion venting plate 1 and internal explosion venting plate 2, thereby realizing the connection and fixation of the connecting rod 6 with the external explosion venting plate 1 and the internal explosion venting plate 2.

[0031] Working principle: This embodiment provides a rock wool core material structure for explosion relief panels used in the petrochemical industry. First, the outer explosion relief panel 1, the inner explosion relief panel 2, the explosion-proof pressure relief keel 3, and the rock wool layer 4 form an explosion relief structure, which is installed in the chemical production environment to achieve the effect of explosion pressure relief protection. When the explosion pressure relief keel 3 is subjected to explosion pressure, the wave crests and troughs will bend and compress, thereby effectively buffering the pressure and reducing the damage to the overall structure. In addition, during the pressure relief process, the wave-shaped explosion-proof pressure relief keel 3 can guide the airflow to pass through the pressure relief channel more evenly. Due to the undulation of the waves, the airflow will be dispersed into multiple directions when passing through the gaps of the explosion-proof pressure relief keel 3, avoiding uneven pressure relief caused by local airflow concentration, thereby improving the pressure relief effect and greatly ensuring the explosion relief protection effect of the structure.

[0032] Secondly, the connecting rod 6 and the explosion-proof pressure relief keel 3 are combined to form an integral structure, thereby achieving the overall positioning effect of each explosion-proof pressure relief keel 3. This prevents the explosion-proof pressure relief keel 3 from being misaligned when it is subjected to explosion pressure, thus affecting the explosion relief protection effect. When the explosion gas flows through the gap of the explosion-proof pressure relief keel 3, the trapezoidal guide groove 302, which is wider at the top and narrower at the bottom, can guide the airflow to flow more orderly, further improving the airflow dispersion effect and preventing the airflow from forming turbulence in local areas.

[0033] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
