Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of barrier explosion suppression, and particularly relates to a nonmetal barrier explosion suppression ball. BACKGROUND

[0002] In recent years, with the development of national economy, flammable and explosive liquid (gas) such as gasoline, liquefied gas and propane are applied more and more widely in daily production and life. Generally, the above flammable and explosive liquid (gas) is stored in a fuel tank.

[0003] The fuel tank, namely the oil container, is a device for storing fuel oil on a machine driven by a diesel engine or a gasoline engine. Generally, the space above the liquid level of the fuel tank is full of flammable gas, and when there is a fire source, the fire source will ignite the adjacent gas, and if the combustion of the gas is not limited, it will spread rapidly. Due to ignition and flame propagation, an increasing pressure wave will be generated in front of the flame front, which will compress the unburned gas, causing the tank to explode, and the whole process only takes a few milliseconds.

[0004] Therefore, during production, transportation, storage and use, combustion and explosion accidents often occur due to improper safety measures or accidents, often causing significant property damage and casualties. Therefore, more and more people pay attention to the suppression of dangerous chemical fire and explosion.

[0005] AQ3001-2005 "Technical Requirements for Barrier Explosion-Proof Storage Tanks for Automobile Gas Stations, Light Fuel and Liquefied Petroleum Gas Tank Trucks" points out that the barrier explosion-proof material should not have debris in the storage tank, otherwise it will affect the normal work of the storage tank itself and the next process of the storage tank. The aluminum alloy explosion suppression material has large internal crystals, which leads to large brittleness, low ductility, poor rust resistance and other disadvantages, and is easy to break and drop slag; in severe cases, it may even cause oil line blockage, resulting in oil line ignition failure, and the material is easy to affect the stability index (induced body, actual gum), cleanliness index (solid particles) and water-soluble acid and alkali index of the oil product during long-term soaking process, affecting the quality of the oil product; the debris can block the oil table, causing it to be unable to rotate and accurately measure the oil quantity; in addition, the edges of the aluminum foil may crack, affecting the explosion suppression performance of the material.

[0006] Therefore, the plurality of explosion-proof small balls can be filled into the combustible and explosive liquid container, thereby dividing the inner cavity of the container into a plurality of "chambers" or "cavities", which can effectively suppress the propagation of flame and sharply attenuate the explosion pressure wave. Meanwhile, the explosion-proof small balls have high surface efficiency in unit volume, thereby having good heat absorption, can rapidly absorb the heat released by combustion, reduce the temperature after combustion reaction, reduce the expansion degree of reaction gas, and increase the pressure value in the container, so that the combustion speed does not reach the limit speed of explosion. When the combustible and explosive liquid in the container is about to explode due to impact, high temperature, gun shooting, artillery shooting and the like, the explosion-proof small balls can absorb and suppress the explosion energy, thereby eliminating the risk of explosion of the combustible and explosive liquid and achieving the purpose of explosion suppression.

[0007] Among them, the non-metal barrier explosion-proof ball usually has the following key parameters: (1) duty cycle: refers to the percentage of the real volume of all balls to the volume of the container when the container of a certain volume is filled with explosion-proof balls. The smaller the ratio, the smaller the reduction in the volume of the container caused by the balls, the more liquid can be loaded, that is, in principle, under the premise of meeting the explosion-proof effect, the smaller the volume of the explosion-proof ball, the smaller the volume consumed; (2) specific surface area: refers to the total surface area of the balls loaded in the container, the larger the better; (3) angle transmittance: refers to the ratio of the light-transmitting area to the projected outline area after the projection of the ball at a certain angle, the smaller the better, the smaller the ratio, the smaller the light-transmitting area.

[0008] To address the aforementioned problems, patent application number 201210232080.4, entitled "A Non-metallic Barrier and Explosion Suppression Ball," discloses a non-metallic barrier and explosion suppression ball that uses non-metallic materials instead of metallic materials. The ball comprises an upper tubular structure, a lower tubular structure, an arc-shaped plate, an annular plate, and a circular plate. These components form a hollow grid-like sphere. The upper and lower tubular structures are respectively located at the upper and lower ends of the sphere, coaxial with the sphere. Four arc-shaped plates are symmetrically arranged around the upper and lower tubular structures. Three to five annular plates are inserted perpendicularly into the arc-shaped plates along the sphere's axis. Two circular plates are also present. The quantity consists of two circular pieces, each with a rectangular hole in the center. The circular piece is parallel to the axis of the sphere and perpendicular to a pair of arc-shaped pieces inserted into the arc-shaped and annular pieces. The two short sides of the rectangular hole coincide with two annular pieces near the upper and lower tubular structures, respectively. Small rectangular holes are provided in the area separated by the annular pieces and arc-shaped pieces near the upper and lower tubular structures on the circular piece. These small rectangular holes are located within the right-angled area formed by the arc-shaped and annular pieces. The circular piece has a circular hole. This technical solution has a large volume, small holes, and poor permeability, thus affecting the amount of liquid that can be loaded into the container and the liquid filling volume. Furthermore, it easily forms bubbles, which contain oxygen, providing the necessary conditions for an explosion and failing to achieve the desired safety and explosion-proof effect.

[0009] Patent application number 201210447134.9, patent title: "A Non-metallic Barrier Explosion Suppression Sphere," discloses a non-metallic barrier explosion suppression sphere comprising: a circular plate, a semi-circular arc-shaped plate, an upper annular structure, and a lower annular structure; the circular plate, semi-circular arc-shaped plate, upper annular structure, and lower annular structure constitute a hollow grid-like sphere; the upper annular structure and lower annular structure are respectively disposed at the upper and lower ends of the sphere, coaxial with the sphere; the semi-circular arc-shaped plate is symmetrically disposed around the axis of the sphere and intersects with the upper and lower annular structures; the circular plate is disposed at the equator of the sphere and perpendicularly intersects with the semi-circular arc-shaped plate, and is fixedly connected to the semi-circular arc-shaped plate. It is composed of a plastic composition with high solvent resistance, exhibiting long lifespan, high stability, no need for replacement, very low volume fraction in containers, higher mechanical properties, and no collapse. However, to ensure a certain structural strength, the sphere in this technical solution has a relatively large wall thickness at various points, resulting in a large overall volume and a large sphere occupancy ratio.

[0010] Application No.: 201410421570.8, Patent Name: A Non-metallic Explosion-proof Sphere, discloses a non-metallic explosion-proof sphere including an equatorial ring, a longitude plate, an Antarctic ring, and an Arctic ring; the equatorial ring and the longitude plate are arranged vertically; the Antarctic ring and the Arctic ring are respectively located on both sides of the equatorial ring; the Antarctic ring is located at one end of the longitude plate, and the Arctic ring is located at the other end of the longitude plate; the equatorial ring, the Antarctic ring, and the Arctic ring are coaxial; along the axial direction of the equatorial ring, the projection of the Antarctic ring is located inside the projection of the equatorial ring; the projection of the Arctic ring is located inside the projection of the Antarctic ring; the projection of the longitude plate extends from the projection of the Arctic ring to the equatorial ring. In this technical solution, the transparency ratio of the sphere at various angles is large, which affects the explosion-proof effect.

[0011] Therefore, improvements are needed. Summary of the Invention

It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0032] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] like Figures 1-4 As shown in the embodiments of this utility model, a non-metallic barrier explosion-suppressing ball is provided for filling a container of flammable and explosive liquids. When the flammable and explosive liquid in the container is about to explode due to impact, high temperature, gunshot, artillery fire, etc., it absorbs and suppresses the explosion energy, thereby eliminating the risk of explosion of the flammable and explosive liquid.

[0035] In an embodiment of this utility model, a non-metallic barrier explosion-suppressing ball includes: an Arctic cylindrical ring 1, a North latitude cylindrical ring 2, an equatorial ring 3, a South latitude cylindrical ring 4, an Antarctic cylindrical ring 7, a longitude main support plate 5, and a longitude secondary support plate 6. The Arctic cylindrical ring 1 and the Antarctic cylindrical ring 7 are coaxial, and the size of the Antarctic cylindrical ring 7 is 1.1-1.2 times the size of the Arctic cylindrical ring 1. The coaxiality of the Arctic cylindrical ring 1 and the size of the Antarctic cylindrical ring 7 is designed to reduce vertical permeability, which helps to hinder energy propagation and improve the flame-retardant and explosion-suppressing effect. The flame-retardant and explosion-suppressing effect is best when the Arctic cylindrical ring 1 and the Antarctic cylindrical ring 7 are coaxial and the size of the Antarctic cylindrical ring 7 is 1.15 times the size of the Arctic cylindrical ring 1.

[0036] like Figures 1-4 As shown in the embodiment of this utility model, the upper end of the longitude main support plate 5 is connected to the North Pole ring 1 and the lower end is connected to the South Pole ring 7. The longitude main support plate 5 is evenly distributed in a circumferential array with the axis coaxial with the North Pole ring 1 and the South Pole ring 7 as the reference. The longitude main support plate 5 is provided with liquid flow holes 8. The longitude secondary support plate 6 consists of several pieces, and one longitude secondary support plate 6 is provided between every two adjacent longitude main support plates 5. The secondary support plate 6 is an arc-shaped piece without holes, mainly to hinder energy propagation and improve the flame retardant and explosion suppression effect.

[0037] like Figures 1-4 As shown, in an embodiment of this utility model, the equatorial ring 3 intersects and is perpendicular to the longitude main support plate 5, and is used to bisect the non-metallic barrier and explosion suppression ball. The equatorial ring 3 is an annular plate, or it can be an annular wavy plate.

[0038] like Figures 1-4 As shown, in an embodiment of this utility model, a north latitude column ring 2 is provided north of the equatorial ring 3, and a south latitude column ring 4 is provided south of the equatorial ring 3. The north latitude column ring 3 and the south latitude column ring 4 have different sizes, which is used to improve the permeability of the non-metallic barrier explosion suppression ball.

[0039] like Figures 1-4 As shown, in an embodiment of this utility model, the longitude main support plate 6 is an arc-shaped thin sheet with a "U"-shaped liquid flow hole 8 to facilitate liquid flow.

[0040] like Figures 1-4 As shown, in an embodiment of this utility model, the liquid flow orifice includes a top end 81, a first support end 82, and a second support end 83, and the top end 81 of the liquid flow orifice exceeds the height of the north latitude column ring 2.

[0041] like Figures 1-4As shown, in an embodiment of this utility model, the Antarctic column ring 7 and the South Latitude column ring 4 are connected by a reinforcing rib 9. When viewed from the North Pole column ring 1 toward the Antarctic column ring 7, the projections of the longitude main support piece 5, the longitude secondary support piece 6, and the reinforcing rib 9 do not overlap. The reinforcing rib 9 includes a full-width reinforcing rib 91 and a half-width reinforcing rib 92. A half-width reinforcing rib 92 is provided between every two adjacent full-width reinforcing ribs 91. The half-width reinforcing rib 92 increases the flowability of liquid, while the full-width reinforcing rib 91 hinders the propagation of energy.

[0042] like Figures 1-4 As shown, in an embodiment of this utility model, the Antarctic column ring 7 is connected to the support end 82 of the liquid flow hole 8, and the South Latitude column ring 4 is connected to the support end 83 of the liquid flow hole 8.

[0043] like Figures 1-4 As shown, in an embodiment of this utility model, one end of the longitude secondary support plate 6 is connected to the north latitude column ring 2, and the other end of the longitude secondary support plate 6 is connected to the south latitude column ring 4.

[0044] like Figures 1-4 As shown in the embodiment of this utility model, a support frame 11 is also provided on the North Pole ring. The support frame 11 is used to block the liquid flowing from the direction of the South Pole ring 7. The support frame is in the shape of a cross and forms several holes with the North Pole ring 1 for the flow of liquid.

[0045] like Figures 1-4 As shown in the embodiment of this utility model, when viewed from the direction of the North Pole ring 1 towards the direction of the South Pole ring 7, the North Pole ring 1, the North Latitude ring 2, the Equatorial ring 3, the South Latitude ring 4, and the South Pole ring 7 are not on the same projection plane.

[0046] like Figures 5-7 As shown in the embodiments of this utility model, the working principle of the non-metallic barrier explosion suppression ball in the container is as follows: The container is filled with non-metallic barrier explosion suppression balls, and as few non-metallic barrier explosion suppression balls as possible are used to fill the container to form a complex spatial maze structure (interconnected to each other and without any closed areas). The maze walls are used to block energy transmission and absorb energy. Semi-closed areas must be avoided, as the formation of bubbles will make it easier for oxygen to explode and will also reduce the amount of liquid contained.

[0047] When liquid flows from the North Latitude Pillar Ring 2 of a non-metallic barrier explosion-suppressing sphere to the South Pole Pillar Ring 7, the Longitude Main Support Plate 5 divides the incoming energy into several parts. As the liquid flows through the Longitude Secondary Support Plate 6, it is further subdivided, and the energy weakens. When it reaches the Equatorial Ring 3, due to the blocking effect of the Equatorial Ring 3, the energy is divided into two parts. One part flows to other non-metallic barrier explosion-suppressing spheres, and the other part enters the interior of the sphere and flows to the South Pole Pillar Ring 7. The reinforcing ribs 9 on the South Pole Pillar Ring 7 further cut and divert the energy, directing it to other smaller spheres. This repeated process of blocking and decomposing energy achieves the explosion-proof function.

[0048] When liquid enters the interior of a non-metallic explosion-proof ball from the equatorial ring 3 (east-west direction), the main longitude support plate 5 and the secondary longitude support plate 6 are arranged in a circular array. Therefore, there is an angle between each pair of adjacent main longitude support plates 5 and secondary longitude support plates 6, which will block part of the liquid's energy. At the same time, the north latitude column ring 2 and the south latitude column ring 4 will also block the flow of liquid, reduce the propagation of energy, and achieve explosion prevention.

[0049] When liquid flows from the south pole ring 7 of a non-metallic barrier explosion-proof ball to the north pole ring 1, the support frame 9 on the north pole ring 1 divides the energy to achieve the explosion-proof function.

[0050] Since the Arctic ring 1, the North latitude ring 2, the equatorial ring 3, the South latitude ring 4, and the South pole ring 7 are not on the same projection plane and are not on the same projection plane as the reinforcing rib 9 of the South pole ring 7, every unit of energy propagated by the liquid can be cut off and blocked, thus achieving explosion protection.

[0051] like Figures 5-7 As shown in the embodiments of this utility model, the non-metallic barrier explosion-suppressing ball is transparent and has a small mass, so it has a very low volume occupancy in the container, and more liquid can be placed in the same volume of the box.

[0052] Furthermore, the sphere has a large total surface area, a small duty cycle, high transparency at all angles, and good explosion-proof performance. Under the premise of meeting the explosion-proof performance requirements, it can hold more liquid.

[0053] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
