Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, and in particular to a leak-proof structure for oil and gas recovery equipment. Background Technology

[0002] Oil and gas recovery utilizes one or more processes such as absorption, adsorption, or condensation to either reduce oil and gas pollution or convert them from a gaseous state to a liquid state, reverting them back to gasoline for reuse. Oil and gas recovery is an energy-saving and environmentally friendly new technology. It recovers oil and gas emitted during storage, transportation, and loading / unloading, preventing air pollution caused by oil and gas volatilization, eliminating safety hazards, and improving energy utilization efficiency while reducing economic losses, thus yielding considerable economic benefits. Common methods include adsorption, absorption, condensation, and membrane separation systems. Leak-proof structures must be installed on oil pipelines during oil and gas recovery.

[0003] A search revealed that patent CN218032053U discloses a leak-proof structure for an oil and gas recovery device; however, this leak-proof structure has the following shortcomings in use:

[0004] Although the anti-leakage mechanism can be cushioned by springs during use, the seal between the anti-leakage outer cover and the anti-leakage outer box is poor. Oil and gas inside the anti-leakage outer box can easily leak out from between the cover and the outer box, which is quite inconvenient. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that although the anti-leakage mechanism can be buffered by springs during use, the sealing between the anti-leakage outer cover and the anti-leakage outer box is poor, and the oil and gas inside the anti-leakage outer box can easily leak out from between the anti-leakage outer cover and the anti-leakage outer box, which is quite inconvenient. Therefore, this utility model proposes an anti-leakage structure for oil and gas recovery equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A leak-proof structure for an oil and gas recovery device includes a base, a leak-proof box, an air pump for transporting oil and gas, and an oil and gas pressure gauge for detecting the oil and gas inside the leak-proof box. A box cover is hinged to one side of the leak-proof box, and an mounting plate is welded to another side. The bottom of the air pump is fixedly connected to the top of the mounting plate. An external pipe is fixedly installed on one side of the leak-proof box and is in communication with it. The oil and gas pressure gauge is installed on the external pipe, and a first valve is installed on the external pipe. A first pipe is fixedly installed at the extraction port of the air pump, and a fixed pipe is fixedly installed at the output port of the air pump. The other end of the fixed pipe passes through the leak-proof box and extends into it. Three slots are provided on both inner walls of the leak-proof box, and mesh plates for slowing down the oil and gas flow are inserted into two adjacent slots.

[0008] A sealing mechanism is installed between the leak-proof box and the box cover to improve the sealing performance between the leak-proof box and the box cover.

[0009] The fixing mechanism is installed on the leak-proof box and the box cover to secure the leak-proof box and the box cover together.

[0010] In one possible design, the sealing mechanism includes a raised strip and a sealing ring. The bottom of the raised strip is fixedly connected to the top of the leak-proof box. The raised strip is U-shaped. The bottom of the box cover has a groove that matches the raised strip. The top of the sealing ring is fixedly connected to the inner wall of the top of the groove.

[0011] In one possible design, the fixing mechanism includes a first fixing plate, a second fixing plate, and two bolts. One side of the first fixing plate is welded to one side of the box cover, and one side of the second fixing plate is welded to one side of the leak-proof box. The first fixing plate has two through holes, and the second fixing plate has two threaded holes. One end of the bolt passes through the through holes and is threadedly connected to the threaded holes.

[0012] In one possible design, a drain pipe is fixedly installed on one side of the leak-proof box to facilitate the discharge of liquid from the leak-proof box, and a second valve is installed on the drain pipe.

[0013] In one possible design, dampers for cushioning the leak-proof box are fixedly installed at the top four corners of the base. Springs are sleeved on the dampers. The top of the dampers and the top of the springs are fixedly connected to the bottom of the leak-proof box. The bottom of the springs is fixedly connected to the top of the base. Mounting holes for easy installation are provided at the four corners of the base.

[0014] In one possible design, a placement box is fixedly provided on the top side of the base, and a wrench for turning bolts is placed inside the placement box. A cover is installed on one side of the placement box via a hinge.

[0015] In one possible design, a magnet for magnetically securing the lid is fixedly installed on one side of the top of the placement box, and an iron sheet is fixedly installed on the bottom of the lid.

[0016] In this application, before use, three mesh plates are inserted into the slots of the leak-proof box, and then the box lid is closed. The box lid rotates via a hinge. When the box lid is closed, the protrusions insert into the grooves and achieve a tight seal through the sealing ring to prevent oil and gas leakage. A wrench can then be retrieved from the placement box, and the bolts are turned to connect the first and second fixing plates, thus securing the leak-proof box and the box lid. During the fixing process, the sealing ring is pressurized to further improve the sealing performance. The air pump and oil / gas pressure gauge are powered by an external power source. Controlled by the controller, when the air pump is working, oil and gas can be drawn into the leak-proof box through the first pipe and the fixed pipe for subsequent processing. The mesh plate can effectively reduce the flow rate of oil and gas in the leak-proof box, initially buffering and increasing stability, extending the service life of the leak-proof box. The leak-proof box is supported by springs and dampers, which can also play a certain role in shock absorption. It can avoid placing the pipe directly on the ground or burying it underground, and enhance the corrosion resistance of the device. The materials of the sealing ring and the spring can be selected according to actual needs.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, the leak-proof structure of the oil and gas recovery equipment, through the sealing mechanism, when the box cover is closed, the convex strip will be inserted into the groove, and a tight seal will be achieved through the sealing ring to prevent oil and gas leakage. During the fixing process of the leak-proof box and the box cover, the sealing ring will also be pressurized to further improve the sealing performance.

[0019] In this utility model, the leak-proof structure of the oil and gas recovery equipment is fixed by a fixing mechanism. The first fixing plate and the second fixing plate are connected by turning the bolt with a wrench, thereby fixing the leak-proof box and the box cover.

[0020] In this invention, the sealing mechanism can effectively improve the sealing performance between the leak-proof box and the box cover to prevent oil and gas leakage, and the fixing mechanism can fix the leak-proof box and the box cover. Attached Figure Description
