Description

Technical Field

[0001] This utility model relates to the field of natural gas buffer tank technology, and more specifically, to an improved natural gas buffer tank. Background Technology

[0002] Natural gas buffer tanks are key pressure-bearing equipment in natural gas transmission, storage and use systems. Their core function is to "balance pressure fluctuations and stabilize gas flow supply", while also serving auxiliary functions such as temporary storage and impurity separation.

[0003] A search revealed CN218402000U, which discloses a buffer tank, relating to the field of buffer tank technology. Addressing existing problems, the following solution is proposed: a vibration damping mechanism, a buffer tank body, and a speed reduction mechanism. The buffer tank body is mounted on the top outer wall of the vibration damping mechanism via a bracket. A controller is mounted on one side of the outer wall of the buffer tank body. An air inlet pipe is connected to one end of the top inner wall of the buffer tank body, and an air outlet pipe is mounted on the other end of the top inner wall of the buffer tank body. A first solenoid valve is installed on the air inlet pipe. This invention can dampen the vibration of the tank body when materials enter, thus facilitating production. It can also slow down the speed at which materials enter the tank, preventing material from splashing everywhere and improving the cleanliness of the tank. A pressure gauge allows observation of the air pressure inside the tank, and the controller can control either the first or second solenoid valve to fill or release gas as needed, further aiding in refining.

[0004] However, this buffer tank still has problems in practical applications: although it facilitates the subsequent gas refining process through its gas filling and releasing function, the above technical solution does not include any treatment mechanism for the discharged gas. This not only leads to the direct emission of untreated gas, causing pollution to the surrounding working environment and threatening the health of on-site personnel, but also, due to the flammable nature of natural gas, results in the direct leakage of a large amount of flammable gas, significantly reducing the overall safety factor of the working environment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an improved natural gas buffer tank to solve the problem that although some buffer tanks in the prior art are convenient for gas refining, the discharged gas is not treated, which pollutes the environment, endangers health, and reduces safety due to the discharge of combustible gas.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an improved natural gas buffer tank, comprising...

[0007] The buffer tank body has a discharge pipe fixedly installed at its bottom;

[0008] A filter assembly includes a filter pipe, a plurality of outer shells are slidably fitted onto the inner surface of the filter pipe, a cover plate is installed on the side of each of the plurality of outer shells, a filter medium is disposed in the inner cavity of the outer shell and the cover plate, a plurality of air outlets are opened on the inner surface of the cover plate, a plurality of air inlets are opened on the inner surface of the side of the outer shell away from the cover plate, and a sealing pressure ring is provided at the junction of the outer shell and the cover plate.

[0009] Both ends of the filter pipe are equipped with sealing caps, and the middle of one sealing cap is fixedly installed with the bottom end of the discharge pipe, while the middle of the other sealing cap is fixedly installed with an air outlet pipe.

[0010] The outer surface of the sealing cap is fixedly installed with mounting component one, and the outer surface of the end of the filter pipe is fixedly installed with mounting component two. Fixing blocks are slidably installed on the outer surfaces of mounting component one and mounting component two. Bolts are threadedly connected to the inner surfaces of both sides of the fixing blocks, and the middle part of the bolts is inserted into the middle of mounting component one and mounting component two.

[0011] The buffer tank body has a connecting frame fixedly installed on its outer surface, a shock-absorbing component fixedly installed at the bottom of the connecting frame, and a base plate at the bottom of the shock-absorbing component.

[0012] The shock absorption assembly includes a support plate, with T-shaped blocks fixedly installed on the surfaces of the four corners of the support plate. Brackets are slidably installed on the outer surfaces of the T-shaped blocks, and the bottom of the brackets is fixedly installed on the upper surface of the base plate. Several support rods and several springs are fixedly installed on the lower surface of the support plate. Sleeves are fixedly connected to the bottom ends of the springs. Flexible pads are fixedly installed on the outer surfaces of the sleeves. The lower surface of the flexible pads is fixedly installed on the upper surface of the base plate, and the upper surface is in contact with the lower surface of the support rods.

[0013] The tray has a support fixedly installed in the middle, and the upper surface of the support is in contact with the outer surface of the filter pipe. The upper surface of the tray is fixedly installed with the bottom of the fixing block.

[0014] The air inlets and outlets on the outer shell and the end face of the cover plate are arranged in an alternating pattern, not in a one-to-one correspondence, so that the flow path of the filtered gas in the air passage is W-shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the above scheme, a filtration component is installed. During exhaust pressure stabilization, the gas inside the buffer tank enters the filtration pipe through the discharge pipe, flows in a "W" shape along the staggered air inlets and outlets of the outer shell and cover plate, and is purified by the internal filter medium, thereby achieving the harmlessness of the emitted gas and reducing environmental impact.

[0017] In the above scheme, a shock-absorbing component is installed. When the main body of the buffer tank is subjected to a downward force, the connecting frame transmits the force to the support plate, causing the T-shaped block to slide along the support. The support rod and spring move downward, and when the spring is compressed, the support rod squeezes the flexible pad material to deform, thus offsetting the vibration and impact and buffering the main body of the buffer tank.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides an improved natural gas buffer tank, including...

[0026] The buffer tank body 1 has a discharge pipe 2 fixedly installed at the bottom of the buffer tank body 1;

[0027] The filter assembly 4 includes a filter pipe 40, a plurality of outer shells 41 are slidably sleeved on the inner surface of the filter pipe 40, and a cover plate 42 is installed on the side of each of the multiple outer shells 41. The inner cavity of the outer shells 41 and the cover plate 42 is provided with filter medium 46. The inner surface of the cover plate 42 is provided with a plurality of air outlets 45. The inner surface of the side of the outer shell 41 away from the cover plate 42 is provided with a plurality of air inlets 44. A sealing pressure ring 43 is provided at the junction of the outer shell 41 and the cover plate 42.

[0028] Both ends of the filter pipe 40 are equipped with sealing caps 3, and the middle part of one sealing cap 3 is fixedly installed with the bottom end of the discharge pipe 2, while the middle part of the other sealing cap 3 is fixedly installed with an air outlet pipe.

[0029] Among them, the outer surface of the sealing cap 3 is fixedly installed with mounting part 1 5, the outer surface of the end of the filter pipe 40 is fixedly installed with mounting part 2 6, the outer surfaces of mounting part 1 5 and mounting part 2 6 are slidably installed with fixing block 7, the inner surfaces of both sides of fixing block 7 are threaded with bolt 8, and the middle part of bolt 8 is inserted into the middle of mounting part 1 5 and mounting part 2 6.

[0030] By setting up structures such as mounting component 5 and mounting component 6, when periodically replacing the filter medium 46 inside the outer shell 41, the bolts 8 threaded to the inner surface of the fixing block 7 can be removed first, thereby unlocking mounting component 5 and mounting component 6. At this time, mounting component 5 and mounting component 6 can be slid upwards to disassemble and separate the sealing cover 3 and filter assembly 4 connected to mounting component 5 and mounting component 2. After that, the outer shell 41 and other structures inside the filter pipe 40 can be disassembled, the filter medium 46 can be replaced, and then the components can be reassembled in the original state.

[0031] The buffer tank body 1 has a connecting frame 9 fixedly installed on its outer surface, a shock-absorbing component 10 fixedly installed at the bottom of the connecting frame 9, and a base plate 11 provided at the bottom of the shock-absorbing component 10.

[0032] The shock absorption assembly 10 includes a support plate 100. T-shaped blocks 101 are fixedly installed on the surfaces of the four corners of the support plate 100. Brackets 102 are slidably installed on the outer surfaces of the T-shaped blocks 101. The bottom of the brackets 102 is fixedly installed on the upper surface of the base plate 11. Several support rods 103 and several springs 104 are fixedly installed on the lower surface of the support plate 100. Sleeves 106 are fixedly connected to the bottom ends of the springs 104. Flexible pads 105 are fixedly installed on the outer surfaces of the sleeves 106. The lower surface of the flexible pads 105 is fixedly installed on the upper surface of the base plate 11, and the upper surface is in contact with the lower surface of the support rods 103.

[0033] The tray 100 has a support fixedly installed in the middle, and the upper surface of the support is in contact with the outer surface of the filter pipe 40. The upper surface of the tray 100 is fixedly installed with the bottom of the fixing block 7.

[0034] The air inlet 44 and air outlet 45 on the end face of the outer shell 41 and the cover plate 42 are arranged in an alternating manner, not in a one-to-one correspondence, so that the flow path of the filtered gas in the air passage is W-shaped.

[0035] The working process of this utility model is as follows:

[0036] When the gas inside the buffer tank body 1 is discharged through the discharge pipe 2 to maintain stable gas pressure, the discharged gas will be discharged through the discharge pipe 2 into the filter pipe 40 installed at its bottom end by the sealing cover 3. The gas will continue to flow along the multiple horizontally arranged outer shells 41 and cover plates 42 installed in the inner cavity of the filter pipe 40, with air inlets 44 and air outlets 45. The air inlets 44 and air outlets 45 are staggered and not one-to-one, which can make the flow path of the filtered gas in the gas passage form a "W" shape. During the flow process, the gas is filtered by the filter medium 46 filled inside the outer shell 41. Thus, the gas discharged through the discharge pipe 2 is purified and filtered by the filter assembly 4, so that the finally discharged gas is harmless and the environmental impact is reduced.

[0037] When the buffer tank body 1 is subjected to a downward force, it will transmit the force to the connected support plate 100 through the connecting frame 9 installed on the outer surface. This causes the support plate 100 to drive the T-shaped blocks 101 at the four corners to slide along the inner surface of the bracket 102, and drive the support rod 103 and spring 104 installed on the lower surface of the support plate 100 to move downward. When the spring 104 is compressed into the sleeve 106, the support rod 103 will press the flexible pad 105 that is attached to the bottom and deform. The deformation of the flexible pad 105 can offset some of the vibration force caused by movement or the impact force caused by external force, thereby providing a buffering effect for the buffer tank body 1.
