Description

Technical Field

[0001] This utility model relates to the field of gas storage tank technology, and in particular to a tank that reduces odor leakage. Background Technology

[0002] Odor-absorbing liquid is a specialized safety additive, the main component of which is generally tetrahydrothiophene. Its core function is to impart a distinct and odorous smell to the otherwise colorless and odorless natural gas, so that people can detect leaks immediately and thus prevent accidents.

[0003] Odor-inducing liquid is usually stored in a special storage tank and injected into the gas cylinder continuously and evenly at a standard dosage through a precisely controlled odor-inducing pump. It is usually equipped with a special interface to prevent odor from escaping.

[0004] However, in practical applications, when outdoor or mobile tanks need to be temporarily replenished with odorant, the odorant delivery pipe is usually inserted directly into the tank's filling port (the tank generally has multiple external interfaces for installing filling pipes, safety valves, vent valves, etc.). Because there is a certain gap between the inlet pipe and the tank's filling port (not a dedicated odorant interface structure), gas inside the tank will overflow when adding odorant and evaporate into the air, causing nearby residents to mistake it for a gas leak. This has led to frequent complaints and caused adverse effects. Utility Model Content

[0031] The following is for reference. Figures 1 to 6 This invention describes a tank for reducing odor leakage according to an embodiment of the present invention.

[0032] like Figures 1 to 3As shown, the tank for reducing odor leakage according to an embodiment of the present invention includes a tank body 100, a delivery pipe cover 200, and a gas filter 300. The tank body 100 is provided with a first external connector 110 and a second external connector 120. The delivery pipe cover 200 is fitted onto the first external connector 110. The delivery pipe cover 200 is provided with a through hole 201 through which the delivery pipe 900 can pass. An elastic member 210 is provided inside the delivery pipe cover 200. The elastic member 210 is sleeved on the outside of the delivery pipe 900. When the delivery pipe cover 200 is installed onto the first external connector 110, the elastic member 210 is deformed by the end of the delivery pipe cover 200 and the first external connector 110 so that the elastic member 210 can hold the delivery pipe 900 tightly. The gas filter 300 is connected to the second external connector 120. The gas filter 300 is provided with an adsorbent filter material.

[0033] When odorant needs to be added, the delivery pipe 900 is inserted into the through hole 201, and the elastic element 210 is fitted onto the outside of the delivery pipe 900. When the delivery pipe cover 200 is installed to the first external connector 110, the elastic element 210 is deformed by the end of the delivery pipe cover 200 and the first external connector 110, so that the elastic element 210 can hold the delivery pipe 900 tightly. At the same time, the deformed elastic element 210 is squeezed to fill the gap between the delivery pipe cover 200 and the first external connector 110, which not only satisfies the fixation of the delivery pipe 900, but also seals the gap between the delivery pipe 900 and the first external connector 110, reducing the leakage of odor at the first external connector 110. At the same time, the gas is exhausted through the gas filter 300 at the second external connector 120 to prevent the formation of high pressure inside the tank body 100. Meanwhile, the gas filter 300 can remove the odor of the exhaust gas through the adsorbent filter material.

[0034] It meets the requirements for adding odorous liquid to the tank and reduces odor leakage.

[0035] Specifically, the first external connector 110 and the second external connector 120 can be the original connectors of the gas cylinder, such as connectors used to install filling pipes, safety valves, venting valves, etc., and there is no need to add a specific odor liquid addition port.

[0036] In some embodiments of this utility model, the first external connector 110 and the second external connector 120 may also be configured with switching valves to open or close the first external connector 110 and the second external connector 120 as needed.

[0037] In some embodiments of this utility model, the adsorbent filter material is activated carbon, which has a good adsorption effect and can effectively purify the odor in the exhaust gas.

[0038] Of course, in the specific implementation process, the adsorbent filter material can also be activated alumina particles, bamboo charcoal, nano mineral crystals, etc., all of which have good adsorption effects.

[0039] In some embodiments of this utility model, the elastic element 210 is a ring structure, such as an O-ring or a sealing ring.

[0040] like Figure 2 , Figure 3 As shown, in some embodiments of this utility model, the conveying pipe cover 200 is a threaded end cover with a through hole 201 in its middle. The first external connector 110 is provided with an external thread that mates with the threaded end cover, so that the conveying pipe cover 200 can be screwed onto the first external connector 110 and the elastic member 210 can be squeezed.

[0041] It is understood that in some embodiments of this utility model, the delivery pipe cover 200 can also be installed to the first external connector 110 by means of a pull buckle or other mechanism.

[0042] like Figures 4 to 6 As shown, in some embodiments of this utility model, the gas filter 300 includes a barrel 310 extending vertically, a lower connecting cover 320 located at the lower part of the barrel 310, and an upper exhaust cover 330 located at the upper part of the barrel 310. The lower connecting cover 320 is provided with a connecting part 321 that can be connected to the second external connector 120. The upper exhaust cover 330 is provided with an exhaust pipe 331. A mesh cage 340 for loading adsorbent filter material is provided inside the barrel 310. Gas enters the barrel 310 from the lower connecting cover 320, enters the mesh cage 340 through the mesh holes of the mesh cage 340 and is adsorbed and filtered by the adsorbent filter material. Finally, it is discharged through the exhaust pipe 331 of the upper exhaust cover 330, thereby achieving deodorization of the overflow gas.

[0043] Specifically, the barrel body 310 can be directly made from commonly used pipe fittings, such as cutting galvanized pipes. The lower connecting cover 320 and the upper exhaust cover 330 can be commonly used pipe fittings, such as reducing joints that are compatible with galvanized pipes, which makes the overall structure of the gas filter 300 simple and the manufacturing cost low.

[0044] In some embodiments of this utility model, the connecting part 321 is a pipe structure with internal or external threads, and the second external connector 120 is provided with corresponding external or internal threads so that the connecting part 321 and the second external connector 120 are connected by threaded engagement and satisfy the ventilation function.

[0045] In some embodiments of this utility model, the mesh cage 340 is a barrel-shaped component formed by a mesh plate, with an opening at the top to facilitate the addition of filter material.

[0046] In some embodiments of this utility model, the lower connecting cover 320 and the upper exhaust cover 330 are detachably installed on the barrel body 310 to facilitate the replacement of filter media and the cleaning of the gas filter 300.

[0047] Specifically, the lower connecting cover 320 and the upper vent cover 330 are connected to the barrel body 310 by threaded connection. Of course, in the actual implementation process, the lower connecting cover 320 and the upper vent cover 330 can be installed by means of snap-fit, screw-on or other mechanisms.

[0048] like Figure 5 As shown, in some embodiments of this utility model, there is a gap between the outer side of the mesh cage 340 and the inner wall of the barrel 310 to form odor channels 311 distributed on the outer side of the ring mesh cage 340. The upper part of the odor channel 311 is provided with a blocking structure, and the lower part of the odor channel 311 is an air inlet, that is, the gas can enter the odor channel 311 from bottom to top, and then enter the mesh cage 340 for filtration and absorption, which greatly improves the filtration efficiency.

[0049] Specifically, the odor channel 311 is distributed on the outer periphery of the ring cage 340, thus forming an air inlet surface on the outer periphery of the cage 340. Compared with the traditional bottom air inlet, the filtration efficiency is higher and the utilization rate of the filter material is higher.

[0050] like Figure 5 As shown, in some embodiments of this utility model, the upper part of the mesh cage 340 is provided with an outwardly protruding annular support ring 341, and the inner wall of the barrel 310 is provided with an inwardly protruding annular support boss 312. The mesh cage 340 can be placed into the barrel 310 from top to bottom, and the annular support ring 341 abuts against the annular support boss 312 to form a blocking structure, preventing gas from directly passing upward through the odor channel 311, while meeting the placement requirements of the mesh cage 340.

[0051] like Figure 5 , Figure 6 As shown, in some embodiments of this utility model, a receiving tray 350 is provided below the mesh cage 340. The receiving tray 350 is used to receive the debris of adsorbent filter media such as activated carbon, so as to reduce the occurrence of filter media debris falling into the tank.

[0052] In some embodiments of this utility model, the receiving tray 350 is detachably installed below the wire mesh cage 340 to facilitate the cleaning of the receiving tray 350.

[0053] Specifically, the receiving tray 350 can be detachably installed below the wire mesh cage 340 through threaded connection, snap-fit, or tight fitting.

[0054] It is understood that in some embodiments of this utility model, the receiving tray 350 can be fixedly installed at the bottom of the receiving tray 350 by welding or other means, or the bottom of the receiving tray 350 can be set as a plate without holes.

[0055] like Figure 5As shown, in some embodiments of this utility model, the outer edge of the receiving tray 350 protrudes from the outer side of the mesh cage 340 to further reduce the falling of filter media debris. There is a gap between the outer edge of the receiving tray 350 and the inner wall of the barrel 310 to allow gas to enter the odor channel 311 from bottom to top.

[0056] like Figure 5 As shown, in some embodiments of this utility model, the receiving tray 350 is a downwardly convex inverted conical shell structure to guide the gas flow to the odor channel 311 and reduce gas flow resistance.

[0057] like Figure 6 As shown, in some embodiments of this utility model, the lower end face of the receiving tray 350 is provided with annular and spaced guide protrusions 351. The guide protrusions 351 can guide the gas flowing from bottom to top to diffuse towards the edge of the receiving tray 350, so as to reduce turbulence and improve the smoothness of gas flow.

[0058] like Figure 6 As shown, in some embodiments of this utility model, the guide strip 351 has a spiral extension structure to guide the gas spirally into the odor channel 311 and form a spiral upward state in the odor channel 311, further reducing turbulence, improving the smoothness of gas flow in the odor channel 311, and improving the efficiency of gas flowing into the mesh cage 340, thereby improving the adsorption and filtration effect.

[0059] In some embodiments of this utility model, a one-way valve assembly is provided at the lower connecting cover 320 to allow odorous gas to pass through from bottom to top, so as to reduce the occurrence of foreign objects entering the tank from the gas filter 300 (when no odorous liquid is injected).

[0060] like Figure 5 As shown, in some embodiments of this utility model, the inner wall of the lower connecting cover 320 is a flared structure, and the one-way valve assembly is a one-way ball 322 that matches the flared structure. The weight of the one-way ball 322 is used to realize the one-way control of the lower connecting cover 320.

[0061] like Figures 4 to 6 As shown, in some embodiments of this utility model, the exhaust pipe 331 is provided with a guide 332 that can guide the gas downward and diffuse in all directions, so as to quickly diffuse the exhaust gas and further reduce the impact.

[0062] like Figure 5 and Figure 6As shown, in some embodiments of the present invention, the guide member 332 includes an insert assembly that can be inserted downward into the opening of the exhaust pipe 331. The upper part of the insert assembly is provided with a conical cover 333. There is a gap between the conical cover 333 and the opening of the exhaust pipe 331, and the lower part of the conical cover 333 extends to the outside of the opening of the exhaust pipe 331 and is lower than the opening of the exhaust pipe 331, so as to guide the gas downward and diffuse in all directions.

[0063] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the insert assembly includes at least two insert posts 334. The lower part of the insert post 334 can be inserted into the exhaust pipe 331 and abut against (tightly fit) the inner wall of the exhaust pipe 331. The insert post 334 is provided with a stepped structure that can cooperate with the inner edge of the opening of the exhaust pipe 331, thereby installing the guide 332 into the exhaust pipe 331.

[0064] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
