Description

Technical Field

[0001] This utility model relates to the technical field of methanol refueling structures, and more specifically, to an explosion-proof skid-mounted methanol refueling structure. Background Technology

[0002] Skid-mounted refueling structures, also known as skid-mounted gas stations, are mobile ground-based gas stations that integrate oil storage tanks and refueling machines. Their storage tanks are filled with explosion-proof materials, ensuring they will not explode when exposed to open flames, static electricity, lightning strikes, gunfire, welding, or accidental violent impacts. They possess fireproof and explosion-proof characteristics.

[0003] In the existing technology, most explosion-proof skid-mounted methanol refueling structures are single-layer explosion-proof, and the explosion-proof performance of the barrier explosion-proof material filled in the tank is poor. As a result, the explosion-proof effect of the skid-mounted methanol refueling structure is also relatively poor, which cannot meet the needs of reality. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof skid-mounted methanol refueling structure, which aims to solve the problem of poor explosion-proof performance of existing skid-mounted methanol refueling structures.

[0005] This utility model is implemented as follows: an explosion-proof skid-mounted methanol filling structure includes a tank body and a skid-mounted base. The tank body is mounted on the skid-mounted base and has a tank cavity for storing liquid methanol. The skid-mounted base is equipped with a filling machine for externally filling liquid methanol, and the filling machine is connected to the tank cavity. The tank body includes an inner tank body and an outer tank body that surrounds the inner tank body. The inner tank body surrounds and forms the tank cavity, and a closed enclosure is formed between the outer tank body and the inner tank body. The enclosing interval is filled with an explosion-proof layer made of a metallic explosion-proof material. The explosion-proof layer is connected to both the outer and inner tanks, and divides the enclosing interval into multiple independently arranged partitioned areas. The tank cavity is filled with an explosion-proof unit made of a non-metallic explosion-proof material.

[0006] Furthermore, the explosion-proof unit is spherical, and multiple interconnected hollow areas are formed within the explosion-proof unit, with the hollow areas communicating with the outside of the explosion-proof unit.

[0007] Furthermore, the plurality of hollow regions include a central hollow region formed in the middle of the explosion-proof unit body and an outer peripheral hollow region formed on the outer periphery of the explosion-proof unit body, wherein the outer peripheral hollow region is connected to the central hollow region.

[0008] Furthermore, the outer periphery of the explosion-proof unit has multiple hollow areas, which are arranged at intervals around the outer periphery of the explosion-proof unit. The explosion-proof unit includes multiple sheet-like skeleton plates made of non-metallic explosion-proof material. The skeleton plates intersect with each other, and the hollow areas are formed between adjacent skeleton plates.

[0009] Furthermore, the explosion-proof unit includes multiple sheet-like skeleton pieces, which are made of non-metallic barrier explosion-proof material. The multiple skeleton pieces intersect with each other, and multiple hollow areas are formed between adjacent skeleton pieces.

[0010] Furthermore, the skeleton pieces are hollowed out in the middle to form a hollow area, and the hollow areas of multiple skeleton pieces intersect in the middle of the explosion-proof unit to form the central hollow area.

[0011] Furthermore, the outer periphery of the skeleton piece is arc-shaped, and the two ends of the explosion-proof unit body each have a cylindrical cavity. The inner end of the cavity is connected to the central hollow area, and the outer end of the cavity is connected to the outside of the explosion-proof unit body.

[0012] Furthermore, the explosion-proof layer has multiple hollow, closed-off honeycomb cavities arranged in an array along the extension direction of the explosion-proof layer; the honeycomb cavities respectively penetrate both ends of the explosion-proof layer, the inner end of the explosion-proof layer is connected to the outer periphery of the inner tank, and the outer end of the explosion-proof layer is connected to the inner sidewall of the outer tank. The inner and outer tanks close both ends of the honeycomb cavities so that the honeycomb cavities form the enclosing interval.

[0013] Furthermore, the explosion-proof layer includes a plurality of sequentially adjacent enclosing walls, which enclose the honeycomb cavity.

[0014] Furthermore, a partition layer is provided in the middle of the honeycomb cavity, the partition layer is integrally formed with the explosion-proof layer, and multiple connecting holes are formed in the partition layer.

[0015] Compared with existing technologies, the explosion-proof skid-mounted methanol refueling structure provided by this utility model can eliminate static electricity ignition sources and prevent the possibility of internal fire by setting an explosion-proof layer in the enclosing gap between the outer tank and the inner tank; at the same time, the explosion-proof unit is filled in the tank cavity of the inner tank, which can decompose and extinguish any explosion flames and shock waves that may occur, which can not only effectively control the hazards, but also greatly improve the explosion-proof effect.

[0020] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0021] An explosion-proof skid-mounted methanol filling structure includes a tank body 300 and a skid-mounted base 100. The tank body is mounted on the skid-mounted base 100, and the tank body 300 has a tank cavity 500 for storing liquid methanol. The skid-mounted base 100 is equipped with a filling machine 200 for externally filling liquid methanol, and the filling machine 200 is connected to the tank cavity 500. The tank body 300 includes an inner tank body 301 and an outer tank body 302 that surrounds the inner tank body 301. The inner tank body 301 surrounds and forms the tank cavity 500, and the outer tank body 302 and the inner tank body 301 form a closed enclosure. The enclosing interval is filled with an explosion-proof layer 303, which is made of a metallic explosion-proof material. The explosion-proof layer 303 is connected to the outer tank 302 and the inner tank 301 respectively. The explosion-proof layer 303 divides the enclosing interval into multiple independently arranged partitioned areas. The tank cavity 500 is filled with an explosion-proof unit 400, which is made of a non-metallic explosion-proof material.

[0022] The aforementioned explosion-proof skid-mounted methanol refueling structure, by setting an explosion-proof layer 303 in the enclosing gap between the outer tank 302 and the inner tank 301, can eliminate static electricity ignition sources and prevent the possibility of internal fire; at the same time, the explosion-proof unit 400 is filled in the tank cavity 500 of the inner tank 301, which can decompose and extinguish any explosion flames and shock waves that may occur, which can not only effectively control hazards, but also greatly improve the explosion-proof effect.

[0023] In this embodiment, the explosion-proof unit 400 is spherical, and multiple interconnected hollow areas are formed in the explosion-proof unit 400, with the hollow areas communicating with the outside of the explosion-proof unit 400. The explosion-proof unit 400 is a hollow spherical material with a thin-walled skeleton structure, precisely injection molded from polymer materials. The explosion-proof unit 400 possesses excellent chemical inertness, thermal and electrostatic conductivity, and antibacterial properties. After filling, this material occupies less than 5% of the total volume of the fuel tank or reservoir 300. Without affecting the original function of the vehicle or equipment, it is filled inside the fuel tank or reservoir 300, dividing the internal space into countless tiny spaces. This instantly blocks the propagation path of the explosion shock wave, absorbs the energy of the explosion shock wave, and ensures that the flammable gases inside the fuel tank or reservoir 300 cannot explode.

[0024] Secondly, by making the explosion-proof unit 400 into a hollow sphere, the specific surface area of ​​the material is greatly increased, thereby more effectively quenching flames and improving explosion-proof performance. At the same time, methanol can pass through the explosion-proof unit 400 without obstruction, providing a smooth flow channel for liquid methanol in the tank 300 and improving refueling efficiency. In addition, the hollow structure also reduces the overall weight of the tank.

[0025] In this embodiment, the plurality of hollow regions include a central hollow region 403 formed in the middle of the explosion-proof unit 400 and an outer peripheral hollow region 401 formed on the outer periphery of the explosion-proof unit 400, with the outer peripheral hollow region 401 connected to the central hollow region 403.

[0026] The hollow design of the middle and outer periphery of the explosion-proof unit 400 not only ensures the smooth flow of methanol liquid, but also disperses heat throughout the entire explosion-proof unit 400 in the event of a spark, enabling rapid fire suppression. Furthermore, the hollow structure makes the explosion-proof unit 400 lighter and more material-efficient without compromising its robust and durable performance.

[0027] In this embodiment, the outer periphery of the explosion-proof unit 400 has multiple peripheral hollow areas 401, which are arranged at intervals around the outer periphery of the explosion-proof unit 400. The uniform arrangement of the peripheral hollow areas 401 on the outer ring of the explosion-proof unit 400 ensures that the explosion-proof skid-mounted methanol refueling structure can provide uniform, 360-degree protection against both internally flowing methanol and potential external flames.

[0028] Furthermore, without affecting the smooth flow of methanol and the thorough filling process, the explosion-proof unit 400 acts like a spherical explosion-proof net to block the spread of flames in the event of an accident. This makes the structure of the explosion-proof unit 400 itself more stable and durable.

[0029] In this embodiment, the explosion-proof unit 400 includes a plurality of sheet-like skeleton pieces 404. The skeleton pieces 404 are made of non-metallic barrier explosion-proof material. The plurality of skeleton pieces 404 intersect each other, and a plurality of hollow areas are formed between adjacent skeleton pieces 404.

[0030] The explosion-proof unit 400 is constructed with a skeleton structure composed of many intersecting thin sheets. This not only increases the surface area within a limited space, allowing for better coverage of the flame and weakening its intensity, but also forms a stable channel to ensure smooth flow of methanol.

[0031] In this embodiment, the skeleton plates 404 are hollowed out in the middle to form a hollow area 405. Multiple skeleton plates 404 with hollow areas 405 intersect in the middle of the explosion-proof unit 400, forming a central hollow area 403. Setting the skeleton plates 404 in a hollow state not only improves the flow efficiency of the methanol liquid but also allows the explosion-proof unit to fully exert its explosion-proof and quenching function in a three-dimensional space. Thus, while reducing weight and saving materials, the flowability and explosion-proof performance of the skid-mounted methanol refueling structure are improved.

[0032] In this embodiment, the outer periphery of the skeleton piece 404 is arc-shaped, and the two ends of the explosion-proof unit 400 each have a cylindrical cavity 402. The inner end of the cavity 402 is connected to the central hollow area 403, and the outer end of the cavity 402 is connected to the outside of the explosion-proof unit 400. Setting the shape of the explosion-proof unit 400 to arc-shaped and providing cavities 402 at both ends not only ensures high-speed axial flow of methanol liquid and improves filling efficiency, but also makes it easier to stack the explosion-proof units 400 together.

[0033] In this embodiment, the explosion-proof layer 303 has a plurality of hollow honeycomb cavities 3031 with closed outer periphery. The plurality of honeycomb cavities 3031 are arranged in an array along the extension direction of the explosion-proof layer 303. The honeycomb cavities 3031 respectively penetrate both ends of the explosion-proof layer 303. The inner end of the explosion-proof layer 303 is connected to the outer periphery of the inner tank 301, and the outer end of the explosion-proof layer 303 is connected to the inner sidewall of the outer tank 302. The inner tank 301 and the outer tank 302 close both ends of the honeycomb cavities 3031 so that the honeycomb cavities 3031 form an enclosing interval.

[0034] A honeycomb is a structure composed of hexagonal cells arranged symmetrically with all openings facing down or to one side. It is a typical porous material with a two-dimensional array of cells in the plane and parallel stacking out of the plane, exhibiting a periodic topological distribution.

[0035] By incorporating a honeycomb cavity 3031 structure into the explosion-proof layer, the explosion suppression and impact resistance of the explosion-proof skid-mounted methanol refueling structure are enhanced, and the entire tank is supported as a robust unit, while also improving production and performance. Ultimately, the highest level of safety is achieved with the lightest weight.

[0036] In this embodiment, the explosion-proof layer 303 includes a plurality of sequentially adjacent enclosing walls 3032, which enclose and form honeycomb cavities 3031. By utilizing the enclosing walls 3032 to construct a regular honeycomb array, the explosion-proof layer 303 becomes a robust three-dimensional structural component. In this way, a rigid explosion barrier is formed in each honeycomb cavity 3031, providing a supporting skeleton for the entire tank.

[0037] In this embodiment, a partition layer 3033 is provided in the middle of the honeycomb cavity 3031. The partition layer 3033 is integrally formed with the explosion-proof layer 303, and multiple connecting holes 3034 are formed in the partition layer 3033. By providing a partition layer 3033 with connecting holes 3034 in the middle of the honeycomb cavity 3031, it is equivalent to adding a built-in barrier to each explosion-proof unit 400, which can block flames and shock waves multiple times when passing through, and has a dual explosion-proof effect. Furthermore, while maintaining internal and external pressure balance through the connecting hole 3034, the partition layer 3033 also acts as a natural supporting framework, strengthening the overall structure. Ultimately, the integrated molding process simultaneously enhances the safety protection capability and mechanical strength of the explosion-proof skid-mounted methanol refueling structure.

[0038] Additionally, it should be noted that non-metallic barrier explosion-proof materials mainly include chloroprene rubber, polyurethane foam, ceramic materials, and porous composite materials, all of which can be used in explosion-proof skid-mounted methanol refueling structures.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
