Description

Technical Field

[0001] This utility model relates to the technical field of storage tanks, and in particular to a liquid carbon dioxide storage tank for blasting. Background Technology

[0002] Carbon dioxide blasting is a blasting method used in mining and other environments where open flames are prohibited. It involves compressing liquid carbon dioxide into a blasting cylinder using a high-pressure pump, inserting a safety membrane, fracturing discs, a heat-conducting rod, and a sealing ring, and then tightening the alloy cap to complete the installation. Several boreholes are drilled at a certain distance from the free face in the mine. The blasting cylinder is inserted into the boreholes and secured. After the detonator activates the heat-conducting rod, the high temperature breaks through the safety membrane, causing the liquid carbon dioxide to rapidly vaporize and expand dramatically. The resulting high-pressure gas causes the rock mass to crack.

[0003] To facilitate the filling of liquid carbon dioxide, it is necessary to transport the liquid carbon dioxide storage tank to the blasting site for use. However, the ground at blasting sites is uneven and the environment is complex. Currently used storage tanks have simple structures and lack protective features to cope with complex operating environments, posing a risk of tipping over during use and resulting in poor safety. Therefore, to address these shortcomings, this application proposes a liquid carbon dioxide storage tank for blasting. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a reliable and safe liquid carbon dioxide storage tank for blasting.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A liquid carbon dioxide storage tank for blasting includes: a support frame, a tank body, two arc-shaped carrier plates, and two arc-shaped hoops;

[0007] Two arc-shaped carrier plates are spaced apart within the support frame. The two arc-shaped carrier plates are used to jointly support the tank body. Two arc-shaped hoops are respectively disposed on the two arc-shaped carrier plates. The two arc-shaped hoops are used to clamp the two ends of the tank body together with the two arc-shaped carrier plates respectively.

[0008] The tank body includes an inner tank, an outer tank, and several support brackets. The inner tank is disposed inside the outer tank. Each of the support brackets is disposed at intervals on the outer side wall of the inner tank, and each of the support brackets is connected to the inner side wall of the outer tank, so that several spaced filling cavities are formed between the inner tank and the outer tank. Each filling cavity is provided with a heat insulation block.

[0009] Optionally, an interlayer is further provided on the outer side wall of the inner tank, and a number of spaced partitions are provided between the interlayer and the outer side wall of the inner tank, so that a number of vacuum holes are formed between the interlayer, the outer side wall of the inner tank, and each of the partitions, and each of the support brackets is spaced apart on the side of the interlayer away from the inner tank.

[0010] Optionally, the arc-shaped carrier plate and the arc-shaped hoop are further provided with a clamping strip on the side near the tank body.

[0017] This utility model discloses a liquid carbon dioxide storage tank for blasting, comprising a support frame, a tank body, two arc-shaped carrier plates, and two arc-shaped hoops. The two arc-shaped carrier plates are spaced apart within the support frame and jointly support the tank body. The two arc-shaped hoops are respectively disposed on the two arc-shaped carrier plates and are used to clamp the two ends of the tank body to the two arc-shaped carrier plates. The tank body includes an inner tank, an outer tank, and several support brackets. The inner tank is disposed inside the outer tank, and each support bracket is spaced apart on the outer side wall of the inner tank, and each support bracket is connected to the inner side wall of the outer tank, so that several spaced filling cavities are formed between the inner tank and the outer tank, and a heat insulation block is disposed in each filling cavity.

[0025] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0026] like Figures 1 to 3As shown, a liquid carbon dioxide storage tank 10 for blasting includes a support frame 100, a tank body 200, two arc-shaped carrier plates 300, and two arc-shaped clamps 400. The two arc-shaped carrier plates 300 are spaced apart within the support frame 100 and are used to jointly support the tank body 200. The two arc-shaped clamps 400 are respectively disposed on the two arc-shaped carrier plates 300 and are used to clamp the two ends of the tank body 200 with the two arc-shaped carrier plates 300 respectively. The tank body 200 includes an inner tank 210, an outer tank 220, and several support bars 230. The inner tank 210 is disposed inside the outer tank 220. Each support bar 230 is spaced apart on the outer side wall of the inner tank 210, and each support bar 230 is connected to the inner side wall of the outer tank 220, so that several spaced filling cavities are formed between the inner tank 210 and the outer tank 220. Each filling cavity is provided with a heat insulation block 240.

[0027] It should be noted that the arc-shaped design of the arc-shaped carrier plate 300 conforms to the curved surface of the outer wall of the tank 200, and shares the load of the tank 200 with the support frame 100 through the friction of the contact surface. Two arc-shaped clamps 400 are respectively installed on the arc-shaped carrier plate 300 and fixed by bolts or welding, cooperating with the two arc-shaped carrier plates 300 to circumferentially tighten both ends of the tank 200, ensuring that the tank 200 is reliably fixed on the support frame 100. Furthermore, the inner tank 210 is used to store liquid carbon dioxide, and the outer tank 220 serves as the outer protective layer; the two are connected by the support 230 to form a hollow, heat-insulating double-layer protective structure. Furthermore, to improve the heat insulation between the inner tank 210 and the outer tank 220, heat-insulating blocks 240 are filled into each filling cavity. In one embodiment, the heat-insulating blocks 240 are made of polyurethane foam. Thus, the support frame 100 provides an external support and protection structure for the tank 200. The tank 200 is designed as a double-layer structure with an outer tank 220 and an inner tank 210. The gap between the outer tank 220 and the inner tank 210 forms a filling cavity. On the one hand, this effectively ensures that the liquid carbon dioxide filled in the inner tank 210 is kept at a low temperature. On the other hand, it can effectively improve the overall structural strength of the tank 200. Through a reliable mechanical support structure and a double-layer tank structure, the stability, safety, and efficient heat insulation of liquid carbon dioxide storage are achieved.

[0028] like Figure 4 As shown, in one embodiment, an interlayer 250 is also provided on the outer side wall of the inner tank 210, and a number of spacers 260 are provided between the interlayer 250 and the outer side wall of the inner tank 210, so that a number of vacuum holes 202 are formed between the interlayer 250, the outer side wall of the inner tank 210, and each spacer 260. Each support rib 230 is spaced apart on the side of the interlayer 250 away from the inner tank 210.

[0029] It should be noted that in this embodiment, the tank 200 consists of an inner tank 210, an outer tank 220, and a sandwich layer 250. The sandwich layer 250 is located between the inner tank 210 and the outer tank 220. The sandwich layer 250 is fixed to the outer wall of the inner tank 210 by partitions 260, and the outer tank 220 is fixed to the outer wall of the sandwich layer 250 by supports 230. A vacuum hole 202 is formed between the sandwich layer 250, the outer wall of the inner tank 210, and the partitions 260, and a filling cavity is formed between the sandwich layer 250, the outer tank 220, and the supports 230. The vacuum hole 202 and the filling cavity are independent structures. The vacuum hole 202 is a sealed structure, and a vacuum environment is created by evacuation. Thus, the tank 200 has a three-layer structure. Through the combination of the vacuum layer and the insulation layer, the heat insulation performance and safety performance of the tank 200 are effectively improved. It should be noted that even if the outer tank 220 is accidentally damaged, the liquid carbon dioxide filled in the inner tank 210 can be prevented from heating up and vaporizing due to the effective heat insulation of the vacuum hole 202. Therefore, it is safer to use and can be used stably in complex environments such as blasting mines.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the arc-shaped carrier plate 300 and the arc-shaped hoop 400 are also provided with a clamping strip 500 on the side near the tank body 200.

[0031] It should be noted that, in order to stably fix the tank 200 between the arc-shaped clamp 400 and the arc-shaped carrier plate 300, a clamping strip 500 is installed on the inner side of both the arc-shaped clamp 400 and the arc-shaped carrier plate 300, so that the clamping strip 500 fits snugly against the tank 200. In one embodiment, the clamping strip 500 is made of foam cotton. This ensures that the arc-shaped clamp 400 and the arc-shaped carrier plate 300 reliably and stably clamp and fix the tank 200.

[0032] In one embodiment, the arc-shaped hoop 400 is welded to the arc-shaped carrier plate 300. This ensures that the tank body 200 is reliably fixed to the support frame 100 as a whole, and the support frame 100 protects the tank body 200, improving the safety of the tank body 200 in use, thus making it suitable for complex occasions such as blasting mines.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the bottom of the support frame 100 is provided with several rollers 600. Thus, the rollers 600 facilitate the movement of the liquid carbon dioxide storage tank 10 for blasting within a small area of ​​the blasting mining area, making it more convenient to use.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the top of the support frame 100 is provided with a plurality of spaced-apart hooks 700.

[0035] It should be noted that when the liquid carbon dioxide storage tank 10 for blasting needs to be moved over a long distance, the liquid carbon dioxide storage tank 10 for blasting can be hoisted as a whole through each of the lifting buckles 700.

[0036] like Figure 3 As shown, in one embodiment, the thickness of the support 230 gradually decreases from the outer can 220 to the inner can 210.

[0037] It should be noted that the thickness of the support 230 near the inner tank 210 is less than the thickness near the outer tank 220, and the thickness of the support 230 varies linearly. By reducing the cross-sectional area of ​​the support 230 near the inner tank 210, heat transfer can be reduced, thereby ensuring the low-temperature characteristics of the liquid carbon dioxide inside the inner tank 210.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the tank 200 further includes an inlet pipe 271, an outlet pipe 272, a pressure boosting pipe 273, and a pressure relief valve 274. The inlet pipe 271, the outlet pipe 272, the pressure boosting pipe 273, and the pressure relief valve 274 are all connected to the inner tank 210, and the inlet pipe 271, the outlet pipe 272, the pressure boosting pipe 273, and the pressure relief valve 274 all pass through the outer tank 220 to extend to the outside.

[0039] It should be noted that inlet pipe 271, outlet pipe 272, and pressurization pipe 273 are all equipped with switch valves. Thus, liquid carbon dioxide can be injected into the inner tank 210 through inlet pipe 271, liquid carbon dioxide can be discharged from the inner tank 210 through outlet pipe 272, and nitrogen dioxide can be injected through pressurization pipe 273 to increase the gas pressure inside the inner tank 210. Furthermore, if the gas pressure inside the inner tank 210 becomes too high, the pressure relief valve 274 can release the excessive pressure, ensuring the safe use of the liquid carbon dioxide storage tank 10 for blasting.

[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
