Description

Technical Field

[0001] The utility model relates to the technical field of gas mixing, in particular to a static natural gas aeration mixing mechanism. Background Art

[0002] In industry and energy production, static natural gas mixing mechanisms are often used in gas engines, gas turbines, gas boilers and other equipment. By adjusting the mixing ratio of natural gas and other gases, the mechanism can effectively control the gas mixture supplied to these devices, thereby achieving a more efficient combustion process.

[0003] A Chinese patent discloses a natural gas hydrogen-blended uniform mixing device (authorization announcement number CN215863400U). The patented technology includes a mixing tank and a natural gas jet system, a swirl plate, a hydrogen jet swirl system and a flow equalizing plate arranged in the mixing tank. The natural gas jet system, the swirl plate, the hydrogen jet swirl system and the flow equalizing plate are arranged in sequence from bottom to top in the mixing tank; the swirl direction of the swirl plate is opposite to that of the hydrogen jet swirl system, and the jet direction of the hydrogen jet swirl system is downward; a mixed gas outlet is provided on the top of the mixing tank. The mixing device of the utility model can form natural gas swirls and hydrogen swirls with opposite swirl directions and mutually offset, so that natural gas and hydrogen are fully mixed, which is conducive to the stable combustion of the entire mixed gas and reduces or even avoids the generation of pollutants such as nitrogen oxides and other harmful gases. Compared with the burning of traditional fossil energy, users can reduce the generation of pollutant gases and achieve the purpose of environmentally friendly emissions after using this mixed fuel.

[0004] This patented technology can effectively mix natural gas with other gases when used, but it still has some shortcomings when used. When the place of use is different, the natural gas is mixed with different gases, which requires docking with different gas supply device pipelines. At the same time, after the gas inside the gas storage tank is used up, it is also necessary to disassemble the gas supply pipeline and replace the gas storage tank. However, the existing flange docking method requires the turning of a large number of bolts during the disassembly and assembly process, which is inconvenient when replacing the gas supply equipment. Therefore, those skilled in the art provide a static natural gas blending and mixing mechanism to solve the problems raised in the above background technology. Utility Model Content

[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] See also Figure 1-Figure 5 As shown, this embodiment is a static natural gas aeration mixing mechanism, including a main structure 100;

[0043] The main structure 100 includes a mixing tank 101, a grid plate 106 located inside the mixing tank 101, and an air supply pipe 104 located on one side of the upper end of the mixing tank 101;

[0044] The docking structure 200 includes a mounting frame 201, a motor 207 located inside the mounting frame 201, a gear 211 located at the output end of the motor 207, a tooth plate 202 located at the upper and lower ends of the mounting frame 201, a slide bar 203 fixed at one end of the tooth plate 202, a support plate 212 fixed at one end of the slide bar 203, and a docking pipe 208 embedded in the upper end of the support plate 212;

[0045] The inner walls of the upper and lower ends of the mounting frame 201 are both provided with sliding sleeve brackets 204 that are away from each other. The sliding rod 203 is slidably inserted into the sliding sleeve bracket 204. The ends of the tooth plate 202 that are away from each other are both provided with sliders 206. The inner walls of the upper and lower ends of the mounting frame 201 are both provided with guide rails 205. The sliders 206 are slidably installed on the outer walls of the guide rails 205.

[0046] The opposite ends of the butt joint 208 are each provided with a butt joint 210, the outer wall of the butt joint 210 is a conical surface, and a sealing sleeve is provided on the outer wall of the conical surface;

[0047] A hose 209 is provided at one opposite end of the butt-joint pipe 208, one end of the hose 209 passes through the box 301, and the tooth plate 202 is located at the upper and lower sides of the gear 211, and the tooth plate 202 and the gear 211 are meshed with each other;

[0048] Performing use of the docking structure 200;

[0049] The static natural gas and mixed gas storage equipment are placed at symmetrical positions on both sides of the mixing tank 101, and the output pipeline corresponds to the docking pipe 208. The motor 207 drives the gear 211 to rotate. When the gear 211 rotates, it pushes the two tooth plates 202. The slide rod 203 is slidably supported by the sliding sleeve bracket 204. One end of the tooth plate 202 slides on the guide rail 205 through the slider 206. The tooth plate 202 is slidably supported when it moves, driving the support plate 212 to move away from each other, and then driving the docking pipe 208 to move toward the output pipeline of the static natural gas and mixed gas storage equipment. When plugged into the output pipeline, the docking pipe 208 of the corresponding section is clamped with the inner wall of the pipeline;

[0050] Similarly, when the pipeline is disassembled, the motor 207 rotates in the same direction, driving the docking tube 208 to move relative to each other, thereby realizing the disassembly of the docking tube 208 and the output pipeline of the static natural gas and the blended gas storage device. When the natural gas and the blended gas mixing tank 101 are connected by pipeline and contact docking, the disassembly and assembly of a large number of bolts is avoided, and the disassembly and assembly process is easy and convenient, which is convenient for docking after the blended gas storage device is replaced.

[0051] Example 2

[0052] See also Figure 1-Figure 5 As shown, this embodiment is based on the embodiment 1 and also includes:

[0053] as well as;

[0054] The mixing structure 300 includes a second motor 303, a rotating shaft 304 located at the lower end of the second motor 303, stirring rods 306 distributed in a ring array on the outer wall of the rotating shaft 304, a box 301 located inside the mixing tank 101 and symmetrically distributed, and a Tesla valve 302 distributed in a rectangular array and located at an opposite end of the box 301;

[0057] Using a hybrid structure 300;

[0058] The static natural gas and the mixed gas are transported to the hose 209 through the docking tube 208, and then enter the box 301. When the gas gathers inside the box 301, the internal pressure is increased. When the pressure passes through multiple Tesla valves 302, the internal structure of the Tesla valve 302 accelerates the static natural gas and the mixed gas, and the static natural gas and the mixed gas are quickly mixed during the impact process. When the motor 2 303 drives the shaft 304 to rotate, the upward flowing static natural gas and the mixed gas are mixed by the rotating stirring rod 306. When the mixed gas passes through the filter 105, the filter 105 intercepts the solid matter in the natural gas and the mixed gas, so that the quality of the output gas is improved. The gas is output through the gas delivery pipe 104, and the gas is efficiently mixed to help combustion.
