Description

Technical Field

[0001] This utility model relates to a bulk gas diversion device, specifically a bulk gas mixing and diversion device, belonging to the field of bulk gas technology. Background Technology

[0002] Bulk gases are fundamental gases with large demand and wide application in the industrial sector. They mainly include oxygen, nitrogen, argon, hydrogen, and carbon dioxide, and their purity is usually below 99.999%. Based on their preparation methods, they can be divided into air separation gases (such as oxygen, nitrogen, and argon) and synthesis gases (such as ammonia and methane).

[0003] Utility model patent CN210845987U discloses a uniformly mixing gas mixer, including a mixing tank. A first air inlet pipe is connected to the top right side of the mixing tank, and a second air inlet pipe is connected to the bottom right side of the mixing tank. This utility model solves the problem that most existing gas mixers use a flow divider to achieve gas mixing, and therefore lack the function of uniformly mixing gases. This uniformly mixing gas mixer has the advantage of uniform mixing, improves the mixing efficiency, and shortens the gas mixing processing cycle.

[0004] When using bulk gases in industrial production, multiple gases are mixed and distributed to various processes. Although the mixer in the aforementioned patent shortens the mixing cycle, gas mixing requires an external power source. After the shaft has been running for a long time, the seals are prone to aging, which can lead to gas leakage. If the leaked gas contains flammable gases such as methane, it will pose a threat to the safety of the surrounding environment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a bulk gas mixing and diversion device to solve the above-mentioned problems, such as the need for an external power source for gas mixing and the easy aging of the seals after long-term operation of the rotating shaft, which leads to gas leakage.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: a bulk gas mixing and diversion device.

[0009] It includes a main intake flange and an auxiliary intake flange. The main intake flange is externally provided with a mixing mechanism and a flow splitting mechanism. The mixing mechanism includes a connecting pipe, a mixing pipe, a power rotor, and a stirring screen. Both the main intake flange and the auxiliary intake flange are fixedly connected to the connecting pipe, and the mixing pipe is fixedly connected to the connecting pipe. The flow splitting mechanism includes a flow splitting pipe fixedly connected to the mixing pipe. The surface of the flow splitting pipe is fixedly connected with equidistantly arranged branch flanges.

[0010] Preferably, a power shaft is fixedly connected to the middle of the power rotor blade, and a fixed frame is rotatably connected to one end of the power shaft. The fixed frame is fixedly connected to the connecting pipe. The power rotor blade is located at the air inlet end of the main air inlet flange. The fixed frame is used to position the power rotor blade and improve the stability of the rotation of the power rotor blade.

[0011] Preferably, a power frame is fixedly connected to the surface of the power shaft, and an equidistantly arranged agitator plate is fixedly connected to the middle of the power frame. The outlet direction of the auxiliary air inlet flange is the same as the rotation direction of the agitator plate. A small amount of gas is supplied through the auxiliary air inlet flange to provide thrust to the agitator plate, causing the agitator plate to drive the power frame to rotate, thereby providing axial thrust to the power shaft and making the rotation of the power shaft more stable.

[0012] Preferably, an auxiliary rotating vane is fixedly connected to the other end of the power shaft, and the auxiliary rotating vane is located at the air inlet end of the mixing pipe. A sliding sleeve is fitted around the outside of the power shaft. The rotation of the auxiliary rotating vane is controlled by the gas flow, thereby providing axial thrust to the power shaft. The rotation of the auxiliary rotating vane can control the gas to rotate forward, and can also perform secondary mixing of the gas.

[0013] Preferably, the sliding sleeve has an arc-shaped groove inside, and the other end of the power shaft is rotatably connected to a sliding block, which is slidably connected to the arc-shaped groove. The power shaft controls the circumferential rotation of the sliding block, causing the sliding block to slide inside the arc-shaped groove, thereby controlling the sliding sleeve to slide laterally along the axis of the power shaft.

[0014] Preferably, a limiting rod is fixedly connected to the surface of the sliding sleeve, and a sliding groove is slidably connected to the other end of the limiting rod. The sliding groove is fixedly connected to the mixing pipe. The sliding sleeve is positioned by the sliding groove and the limiting rod, making the lateral sliding of the sliding sleeve more stable. The other end of the power shaft can also be limited by positioning the sliding sleeve.

[0015] Preferably, a connecting rod is fixedly connected to the surface of the sliding sleeve, and the stirring screens are equidistantly arranged on the surface of the connecting rods. The stirring screens are fixedly connected to the connecting rods, and the through holes of the stirring screens are staggered. By sliding the sliding sleeve laterally, the connecting rods drive the stirring screens to swing laterally. Through the staggered through holes, the gas flow path is disrupted, and the gas is mixed again.

[0016] Preferably, a second sliding groove is fixedly connected inside the mixing tube, and a positioning block is slidably connected inside the second sliding groove. The other end of the positioning block is fixedly connected to an adjacent mixing screen. The mixing screen is positioned by the second sliding groove and the positioning block, thereby improving the stability of the mixing screen in lateral sliding.

[0017] This invention provides a mixing and diversion device for bulk gases, which has the following beneficial effects:

[0018] 1. This bulk gas mixing and distribution device delivers various gases into the connecting pipe through the main inlet flange and the auxiliary inlet flange. The pressure generated by the gas flow controls the rotation of the power rotor, which in turn controls the movement of the stirring screen to mix and agitate the gas inside the mixing pipe, thereby improving the bulk gas mixing efficiency. Through the distribution pipe and branch flange, the mixed gas inside the mixing pipe is evenly distributed into the branch pipe, improving the bulk gas mixing and distribution effect.

[0019] 2. This bulk gas mixing and distribution device transmits the rotational force borne by the power rotor blades through the power shaft. The power rotor blades are positioned by the fixed frame to improve the stability of the rotation. A small amount of gas is delivered through the auxiliary inlet flange to provide thrust to the agitator plate, causing the agitator plate to drive the power frame to rotate, thereby providing axial thrust to the power shaft and making the rotation of the power shaft more stable. The rotation of the agitator plate can perform preliminary mixing of various gases. The rotation of the auxiliary rotor blades is controlled by the gas flow, thereby providing axial thrust to the power shaft. The rotation of the auxiliary rotor blades can both control the gas rotation and advance and perform secondary mixing of the gas.

[0020] 3. This bulk gas mixing and distribution device controls the circumferential rotation of a sliding block via a power shaft, causing the sliding block to slide inside an arc-shaped groove. This, in turn, controls the sliding sleeve to slide laterally along the axis of the power shaft. The sliding sleeve is positioned by the first sliding groove and a limiting rod, making its lateral sliding more stable. Positioning the sliding sleeve also limits the other end of the power shaft, improving the stability of the power shaft's rotation. The lateral sliding of the sliding sleeve causes the connecting rod to drive the mixing screen to swing laterally. Through the staggered through-holes, the gas flow path is disrupted, and the gases are remixed, improving the uniformity of the mixture of multiple gases. The mixing screen is positioned by the second sliding groove and a positioning block, improving the stability of the mixing screen's lateral sliding. Attached Figure Description

[0029] This utility model provides a bulk gas mixing and diversion device.

[0030] Example 1:

[0031] Please see Figure 1 , Figure 2 and Figure 3 The system includes a main intake flange 1 and an auxiliary intake flange 2. The main intake flange 1 is externally equipped with a mixing mechanism 3 and a diversion mechanism 4. The mixing mechanism 3 includes a connecting pipe 301, a mixing pipe 302, a power rotor 303, and a stirring screen 315. Both the main intake flange 1 and the auxiliary intake flange 2 are fixedly connected to the connecting pipe 301, and the mixing pipe 302 is also fixedly connected to the connecting pipe 301. The main intake pipe is assembled and connected to the main intake flange 1, thus fixing the main intake pipe to the connecting pipe 301. The auxiliary intake pipe is assembled and connected to the auxiliary intake flange 2, thus fixing the auxiliary intake pipe to the connecting pipe 301. Multiple gases are transported into the interior of the connecting pipe 301 through the main intake flange 1 and the auxiliary intake flange 2. The pressure generated by the gas flow controls the rotation of the power rotor 303. The rotation of the power rotor 303 controls the movement of the stirring screen 315, which mixes and agitates the gas inside the mixing pipe 302, thereby improving the mixing efficiency of bulk gases.

[0032] A power shaft 304 is fixedly connected to the middle of the power rotor 303. One end of the power shaft 304 is rotatably connected to a fixed frame 305, and the fixed frame 305 is fixedly connected to the connecting pipe 301. The power rotor 303 is located at the air inlet end of the main air inlet flange 1. The rotational force borne by the power rotor 303 is transmitted through the power shaft 304, and the fixed frame 305 is used to position the power rotor 303, thereby improving the rotational stability of the power rotor 303.

[0033] A power frame 306 is fixedly connected to the surface of the power shaft 304. An agitator 307 is fixedly connected to the middle of the power frame 306. The outlet direction of the auxiliary air inlet flange 2 is the same as the rotation direction of the agitator 307. A small amount of gas is supplied through the auxiliary air inlet flange 2 to provide thrust to the agitator 307, causing the agitator 307 to drive the power frame 306 to rotate, thereby providing axial thrust to the power shaft 304, making the rotation of the power shaft 304 more stable. The rotation of the agitator 307 can also perform preliminary mixing of various gases.

[0034] Example 2:

[0035] Please see Figure 2 , Figure 3 and Figure 4 The other end of the power shaft 304 is fixedly connected to an auxiliary rotating vane 308, and the auxiliary rotating vane 308 is located at the air inlet end of the mixing pipe 302. A sliding sleeve 309 is sleeved on the outside of the power shaft 304. The rotation of the auxiliary rotating vane 308 is controlled by the gas flow, thereby providing axial thrust to the power shaft 304. The rotation of the auxiliary rotating vane 308 can control the gas to rotate forward and can also perform secondary mixing of the gas.

[0036] The sliding sleeve 309 has an arc-shaped groove 311 inside. The other end of the power shaft 304 is rotatably connected to a sliding block 310, and the sliding block 310 is slidably connected to the arc-shaped groove 311. The power shaft 304 controls the circumferential rotation of the sliding block 310, so that the sliding block 310 slides inside the arc-shaped groove 311, thereby controlling the sliding sleeve 309 to slide laterally along the axis of the power shaft 304.

[0037] A limiting rod 312 is fixedly connected to the surface of the sliding sleeve 309, and the other end of the limiting rod 312 is slidably connected to a sliding groove 313. The sliding groove 313 is fixedly connected to the mixing pipe 302. The sliding sleeve 309 is positioned by the sliding groove 313 and the limiting rod 312, making the lateral sliding of the sliding sleeve 309 more stable. By positioning the sliding sleeve 309, the other end of the power shaft 304 can also be limited, which improves the rotational stability of the power shaft 304.

[0038] A connecting rod 314 is fixedly connected to the surface of the sliding sleeve 309. The stirring screens 315 are equidistantly arranged on the surface of the connecting rod 314. The stirring screens 315 are fixedly connected to the connecting rod 314, and the through holes of the stirring screens 315 are arranged in an alternating pattern. By sliding the sliding sleeve 309 laterally, the connecting rod 314 drives the stirring screens 315 to swing laterally. Through the alternating through holes, the gas flow path is disrupted, and the gas is mixed again, thereby improving the uniformity of the mixture of multiple gases.

[0039] Example 3:

[0040] Please see Figure 2 , Figure 3 and Figure 4 The mixing pipe 302 is fixedly connected to a sliding groove 316, and a positioning block 317 is slidably connected inside the sliding groove 316. The other end of the positioning block 317 is fixedly connected to the adjacent stirring screen 315. The stirring screen 315 is positioned by the sliding groove 316 and the positioning block 317, thereby improving the stability of the stirring screen 315 in the lateral sliding.

[0041] The diversion mechanism 4 includes a diversion pipe 401 fixedly connected to the mixing pipe 302. The surface of the diversion pipe 401 is fixedly connected with equidistantly arranged branch flanges 402. The branch pipes are assembled and connected to the branch flanges 402, and the branch pipes are fixedly connected to the diversion pipe 401. Through the diversion pipe 401 and the branch flanges 402, the gas that has been mixed inside the mixing pipe 302 is evenly diverted to the inside of the branch pipe, thereby improving the mixing and diversion effect of bulk gas.

[0042] In use, this invention works as follows: the main intake pipe is assembled and connected to the main intake flange 1, and the main intake pipe is fixedly connected to the connecting pipe 301. The auxiliary intake pipe is assembled and connected to the auxiliary intake flange 2, and the auxiliary intake pipe is fixedly connected to the connecting pipe 301. Multiple gases are transported into the connecting pipe 301 through the main intake flange 1 and the auxiliary intake flange 2. The flowing air controls the rotation of the power vane 303, which in turn controls the synchronous rotation of the power shaft 304. At the same time, the flowing air provides thrust to the agitator 307, causing the agitator 307 to drive the power frame 306 to rotate. Through the rotation of the agitator 307 and the auxiliary vane 308, the multiple gases are initially mixed. The power shaft 304 controls the circumferential rotation of the sliding block 310, causing the sliding block 310 to rotate in the arc-shaped groove 3. 11. The internal sliding mechanism controls the sliding sleeve 309 to slide laterally along the axis of the power shaft 304. Through the lateral sliding of the sliding sleeve 309, the connecting rod 314 drives the mixing screen 315 to swing laterally. Through the staggered through holes, the gas flow path is disrupted, and the gas is mixed again, improving the uniformity of the mixture of multiple gases. Through the diversion pipe 401 and the branch flange 402, the gas mixed inside the mixing pipe 302 is evenly distributed to the inside of the branch pipe, improving the mixing and diversion effect of bulk gases. Through the above device, the power generated by the gas flow is used to mix the gas multiple times, avoiding the use of an external power source, reducing the number of seals used, improving the sealing effect of the device, and thus improving the mixing and diversion effect of bulk gases.
