Description

Technical Field

[0001] The utility model relates to the technical field of oil storage tanks, in particular to an oil storage tank with a barrier explosion-proof oil and gas recovery device. Background Art

[0002] Inflammable and explosive liquid hazardous chemicals are stored in single-layer or composite double-layer oil tanks. Usually, a breathing valve is installed on the external pipe connected to the oil tank to adjust the pressure in the tank and keep it balanced with the external atmospheric pressure. However, the mixed oil and gas in the oil tank can be exhaled into the atmosphere through the breathing valve through the external pipe. This volatile combustible oil and gas mixture not only pollutes the environment, but also wastes resources. Therefore, it is necessary to recycle the volatilized mixed oil and gas into the oil tank as a reserve.

[0029] Example 1

[0030] See also Figure 1-6 The utility model provides the following technical solutions: an oil storage tank with an explosion-proof oil and gas recovery device includes an outer wall 1, characterized in that: an explosion-proof mechanism 2 is arranged at the bottom of the outer wall 1, a top cover 3 is arranged at the top of the outer wall 1, an oil inlet mechanism 4 is arranged on the upper surface of the top cover 3, a fire-blocking ring 5 is fixedly connected to the upper surface of the outer wall 1, and a honeycomb box 6 is arranged inside the outer wall 1;

[0031] An explosion-proof mechanism 2 is disposed inside the honeycomb-shaped box 6 , and a fire-blocking ring 5 is disposed on the top of the explosion-proof mechanism 2 .

[0032] The bottom of the fire-blocking ring 5 is fixedly connected with a honeycomb box 6 , and the lower surface of the top cover 3 is fixedly connected with the fire-blocking ring 5 .

[0033] Example 2

[0034] See also Figure 3-5 The utility model provides the following technical solutions: an explosion-proof mechanism 2, which includes a bolt 201, a threaded column 202, a bearing 203, a sealing plate 204, a connecting column 205 and a piston 206. The bolt 201 is arranged on the top of the top cover 3, and the bottom of the bolt 201 is fixedly connected with the threaded column 202, and one side of the threaded column 202 is fixedly sleeved with a bearing 203.

[0035] The explosion-proof mechanism 2 also includes an oil outlet cover 207, an annular switch 208, a limiting ring 209, a first oil outlet hole 210, a handle 211, a bottom plate 212, a limiting block 213, a circular groove 214 and a second oil outlet hole 215. The oil outlet cover 207 is arranged at the bottom of the outer wall 1, and an annular switch 208 is movably sleeved on one side of the oil outlet cover 207, and a handle 211 is fixedly connected to one side of the annular switch 208. A limiting ring 209 is fixedly sleeved on one side of the annular switch 208. A first oil outlet hole 210 is opened on one side of the annular switch 208, and a bottom plate 212 is fixedly connected to the bottom of the annular switch 208. The limiting block 213 is fixedly connected to the upper surface of the bottom plate 212. A circular groove 214 is arranged at the bottom of the bottom plate 212, and a second oil outlet hole 215 is arranged at the bottom of the bottom plate 212.

[0036] A circular groove 214 is movably connected to the bottom of the annular switch 208 , and the handle 211 is movably connected to one side of the limit block 213 .

[0037] It needs to be further explained that: when an oil storage tank with an explosion-proof oil and gas recovery device is used, the threaded column 202 is driven to rotate on the bearing 203 by rotating the bolt 201, and the bolt 201 moves up and down on the fire-blocking ring 5. At the same time, the connecting column 205 fixedly connected to the lower surface of the bearing 203 is driven by the threaded column 202 to drive the piston 206 to form a plurality of closed spaces in the honeycomb box 6. When one of the closed spaces is affected, the fuel in other closed spaces will not be affected.

[0038] At the same time, a first oil outlet hole 210 is opened at the bottom of the honeycomb box 6, and a second oil outlet hole 215 is opened on one side of the annular switch 208. The first oil outlet hole 210 does not overlap with the second oil outlet hole 215 when storing oil. At this time, the bottom of the honeycomb box 6 is a closed space. When it is necessary to extract fuel, the control handle 211 drives the annular switch 208 to rotate, so that the first oil outlet hole 210 overlaps with the second oil outlet hole 215 to form an oil delivery passage.

[0039] Example 3

[0040] See also Figure 6 The utility model provides the following technical solution: the oil inlet mechanism 4 includes an oil inlet pipe 401, an annular block 402, a protrusion 403, a spring 404 and a fixing plate 405, the oil inlet pipe 401 is arranged on the upper surface of the top cover 3, the inside of the oil inlet pipe 401 is provided with an annular block 402, the inside of the oil inlet pipe 401 is provided with a protrusion 403, one side of the protrusion 403 is fixedly connected to the spring 404, and one side of the spring 404 is fixedly connected to the fixing plate 405.

[0041] A spring 404 is disposed inside the oil inlet pipe 401 , a fixing plate 405 is fixedly connected to one side of the oil inlet pipe 401 , and a protrusion 403 is movably connected to the bottom of the annular clamping block 402 .

[0042] What needs to be further explained is that: when an oil storage tank with a barrier and explosion-proof oil and gas recovery device is in use, by setting an annular clamping plate 402, when oil is not being transported, the protrusion 403 fits against the inner wall of the oil inlet pipe 401 under the action of the spring 404 to form a closed cavity. When oil storage is required, the force of the oil inlet pipe 401 connected to the oil pipe drives the annular clamping plate 402 to push the protrusion 403, and at this time the closed cavity is opened to form an oil transport passage.

[0043] Working principle: When an oil storage tank with an explosion-proof oil and gas recovery device is used, the threaded column 202 is driven to rotate on the bearing 203 by rotating the bolt 201, and the bolt 201 moves up and down while rotating on the fire-blocking ring 5. At the same time, the connecting column 205, driven by the threaded column 202, drives the piston 206 to form a plurality of closed spaces in the honeycomb box 6. When one of the closed spaces is affected, the fuel in other closed spaces will not be affected.

[0044] At the same time, a first oil outlet hole 210 is opened at the bottom of the honeycomb box 6, and a second oil outlet hole 215 is opened on one side of the annular switch 208. The first oil outlet hole 210 does not overlap with the second oil outlet hole 215 when storing oil. At this time, the bottom of the honeycomb box 6 is a closed space and is less affected by static electricity. When it is necessary to extract fuel, the control handle 211 drives the annular switch 208 to rotate, so that the first oil outlet hole 210 overlaps with the second oil outlet hole 215 to form an oil delivery passage.

[0045] When an oil storage tank with an isolation and explosion-proof oil and gas recovery device is used, by setting an annular clamping plate 402, when oil is not being transported, the protrusion 403 fits against the inner wall of the oil inlet pipe 401 under the action of the spring 404 to form a closed cavity, thereby blocking the influence of the external environment on the inside of the oil storage tank; when oil needs to be stored, the force of the oil inlet pipe 401 connected to the oil pipe drives the annular clamping plate 402 to push the protrusion 403, and at this time the closed cavity is opened to form an oil transport passage.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
