Description

Technical Field

[0001] This utility model relates to the field of explosion-proof materials technology, specifically a novel flame-retardant explosion-proof ball. Background Technology

[0002] Containers and pipelines containing flammable and explosive fluids, such as gasoline, diesel, liquefied petroleum gas, and natural gas, are highly susceptible to explosion and combustion hazards during storage, transportation, delivery, and use, and therefore must be subjected to explosion suppression treatment.

[0003] Adding flame-retardant and explosion-proof spheres to flammable and explosive fluid storage tanks can suppress explosions. Existing flame-retardant and explosion-proof spheres are generally stacked with open compartments between adjacent spheres to form several explosion-proof chambers with a "small room" structure. The explosion-proof chambers divide the inner cavity of the liquid container or pipeline to effectively curb the spread of flames and cause the explosion pressure wave to decay rapidly. At the same time, this structure has high surface efficiency per unit volume and good heat absorption, which reduces the temperature after the combustion reaction, suppresses the flame height, reduces heat radiation, reduces the expansion of the reacting gas, and the pressure value inside the container does not increase much, so that the combustion speed does not reach the explosion limit speed, thereby achieving the purpose of suppressing explosions.

[0004] However, existing flame-retardant and explosion-proof spheres rely on the open compartments between adjacent spheres to stack together to form explosion-proof compartments. The number of explosion-proof compartments per unit volume varies due to the uncertain position of the spheres, resulting in poor stability of explosion-proof performance. Furthermore, the explosion-proof performance needs further improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a novel flame-retardant and explosion-proof ball to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel flame-retardant and explosion-proof ball, comprising several longitudinally distributed first fixing plates and several transversely distributed second fixing plates, wherein the several first fixing plates and several second fixing plates together constitute a spherical structure, and an intercepting plate is provided at the end of the plate body of the first fixing plate and / or the second fixing plate; the angle between the intercepting plate and the plate surface of the first fixing plate or the second fixing plate is 30-150°.

[0007] Furthermore, the thickness of the first fixing plate and the second fixing plate is 0.01-0.3mm, and the width of the intercepting plate is 3-8mm.

[0008] Furthermore, the first fixing plate and / or the second fixing plate are fixed to the central waistline of the interceptor plate.

[0009] Furthermore, the interceptor plate is an arc-shaped plate.

[0010] Furthermore, the curvature of the interceptor plate is the same as the curvature of the spherical structure formed by the plurality of first fixed plates and the plurality of second fixed plates.

[0011] Furthermore, several fixing plates are arranged sequentially along the longitudinal axis of the plurality of first fixing plates, and the first fixing plates are fixedly connected to the plurality of fixing plates to form a circular arrangement; the second fixing plate is composed of several arc-shaped plates fixed to the adjacent first fixing plates, and is generally circular in shape.

[0012] Furthermore, the upper fixing plate at the top and the lower fixing plate at the bottom of the fixing plate are hollow annular plates, while the remaining fixing plates are solid circular plates.

[0013] Furthermore, the upper and lower fixing plates are provided with reinforcing ribs.

[0014] Furthermore, the first fixing plate and / or the second fixing plate have several through holes on their plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This novel flame-retardant and explosion-proof ball has an open spherical or cubic structure, eliminating areas prone to liquid accumulation. When subjected to external pressure, it can evenly distribute pressure between the first and second fixed plates.

[0017] 2. This novel flame-retardant and explosion-proof ball retains the explosion-proof chambers formed between the balls, and also forms multiple smaller explosion-proof chambers inside the ball through the interception plate, the first fixing plate, and the second fixing plate. This can significantly increase the multi-chamber ratio within the unit volume of the flame-retardant and explosion-proof ball and significantly improve the explosion-proof effect.

[0018] 3. The explosion-proof chamber inside this novel flame-retardant and explosion-proof ball is not affected by changes in the ball's position, and the stability of the explosion-proof effect is significantly improved. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] A new type of flame-retardant and explosion-proof ball, such as Figure 1 As shown, it includes several longitudinally distributed first fixing plates 2 and several laterally distributed second fixing plates 3. The specific number of the first fixing plates 2 and the second fixing plates 3 can be designed as needed, for example... Figure 1 The five first fixing plates 2 and three second fixing plates 3 mentioned above.

[0025] The plurality of first fixing plates 2 and the plurality of second fixing plates 3 together constitute a spherical structure, and an intercepting plate 5 is provided at the end of the plate body of the first fixing plate 2 and / or the second fixing plate 3. The angle between the intercepting plate 5 and the plate surface of the first fixing plate 2 or the second fixing plate 3 is 30-150°.

[0026] The first fixing plate 2 and the second fixing plate 3 of the existing flame-retardant and explosion-proof ball are both straight plate structures. The first fixing plate 2 and the second fixing plate 3 form an open cavity. The explosion-proof chamber is mainly formed by the mutual aggregation of the open cavities of each ball to form a structure similar to a "small room" with good sealing properties.

[0027] This invention adds an interceptor plate 5 to the end of one of the first fixing plates 2 or the second fixing plate 3, or to the end of each of the first fixing plate 2 or the second fixing plate 3, such that the interceptor plate 5 forms an angle of 30-150° with the surface of the first fixing plate 2 or the second fixing plate 3. This transforms the open structure of the sphere in the prior art into a structure with a certain degree of enclosure. This enclosure structure also helps to suppress the spread of flames. At the same time, the flame-retardant and explosion-proof spheres can form a well-enclosed "chamber"-like structure. Therefore, this invention retains the explosion-proof structure of the existing flame-retardant and explosion-proof spheres while adding an explosion-proof structure to the sphere itself. The explosion-proof structure of the sphere itself does not change due to changes in the position of the flame-retardant and explosion-proof spheres, thus significantly improving the explosion-proof stability. Simultaneously, the total number of explosion-proof structures per unit volume of the flame-retardant and explosion-proof sphere is significantly increased (one flame-retardant and explosion-proof sphere of this invention has several explosion-proof structures of the sphere itself), thereby significantly improving the explosion-proof effect.

[0028] The flame-retardant properties of this invention are mainly achieved by using flame-retardant materials to prepare the spheres of this invention. The flame-retardant materials used are the same as or similar to those used in existing flame-retardant explosion-proof spheres.

[0029] Example 2

[0030] Based on the novel flame-retardant and explosion-proof ball of Embodiment 1, the thickness of the first fixing plate 2 and the second fixing plate 3 is 0.01-0.3mm, and the width of the interception plate 5 is 3-8mm.

[0031] Because this utility model adds an interceptor plate 5, it improves the explosion-proof performance while also increasing the quality of flame retardant explosion-proof. Therefore, an excessively large interceptor plate 5 will lead to an excessive increase in mass (i.e., material cost), while an excessively small interceptor plate 5 will lead to a decrease in the explosion-proof effect.

[0032] The configuration of this embodiment allows the flame-retardant and explosion-proof sphere to have good structural strength while also having a good interception-mass efficiency ratio.

[0033] Example 3

[0034] Based on the novel flame-retardant and explosion-proof ball of Embodiment 1 or Embodiment 2, such as Figure 1 As shown, the first fixing plate 2 and / or the second fixing plate 3 are fixed to the central axis of the interceptor plate 5. This arrangement facilitates processing, and the symmetrically arranged interceptor plates 5 are also more aesthetically pleasing.

[0035] Example 4

[0036] Based on the novel flame-retardant and explosion-proof ball of Example 1, such as Figure 1 As shown, the interceptor plate 5 is an arc-shaped plate. The arc-shaped design of the interceptor plate 5 significantly improves the rolling properties of the flame-retardant and explosion-proof ball.

[0037] Example 5

[0038] Based on the novel flame-retardant and explosion-proof ball of Example 4, such as Figure 1 As shown, the curvature of the interceptor plate 5 is the same as the curvature of the spherical structure formed by the plurality of first fixing plates 2 and the plurality of second fixing plates 3. This arrangement can further improve the rolling performance of the flame-retardant and explosion-proof ball, while also enabling the interceptor plate 5 to produce the best obstruction effect against the shock wave generated by the explosion.

[0039] Example 6

[0040] Based on the novel flame-retardant and explosion-proof ball of Example 1, such as Figure 1 As shown, several fixing plates are arranged in a horizontal direction along the longitudinal axis of the plurality of first fixing plates 2. The first fixing plates 2 are fixedly connected to the plurality of fixing plates to form a circular arrangement. The second fixing plate 3 is composed of several arc-shaped plates fixed to the adjacent first fixing plates 2, and is generally circular in shape.

[0041] This design further enhances the structural strength of the flame-retardant and explosion-proof spheres of this invention, preventing the stacked flame-retardant and explosion-proof spheres from crushing the lower flame-retardant and explosion-proof spheres and affecting the explosion-proof effect.

[0042] Example 7

[0043] Based on the novel flame-retardant and explosion-proof ball of Example 1, such as Figure 1 As shown, the upper fixing plate 1 at the top and the lower fixing plate 8 at the bottom of the fixing plate are hollow annular plates, while the remaining fixing plates are solid circular plates 7.

[0044] The upper fixing plate 1 and the lower fixing plate 8 are configured as hollow annular plate structures, which allows the fluid to flow smoothly through the flame-retardant and explosion-proof ball of this utility model, avoiding the flame-retardant and explosion-proof ball occupying ineffective space in the fluid.

[0045] Example 8

[0046] Based on the novel flame-retardant and explosion-proof ball of Example 7, such as Figure 1 As shown, the upper fixing plate 1 and the lower fixing plate 8 are provided with reinforcing ribs 6. This feature can further enhance the structural strength of the flame-retardant and explosion-proof ball of this utility model.

[0047] Example 9

[0048] Based on the novel flame-retardant and explosion-proof ball of Example 1, such as Figure 1 and Figure 2 As shown, the first fixing plate 2 and / or the second fixing plate 3 have several through holes 9.

[0049] The through hole 9 can reduce weight on the one hand, and further allow the fluid to flow smoothly through the flame-retardant and explosion-proof ball of this utility model, avoiding the flame-retardant and explosion-proof ball occupying ineffective space in the fluid.

[0050] 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.
