Description

Technical Field

[0001] This utility model belongs to the field of rare earth calcination furnace technology, and in particular relates to a rapid cooling mechanism for exhaust gas from a rare earth calcination furnace. Background Technology

[0002] Rare earth elements exist in minerals in the form of compounds such as oxides, carbonates, and oxalates. They need to be calcined at high temperatures in a rare earth calcination furnace to break the original chemical bonds, thereby removing impurities, transforming structures, or improving purity to meet the needs of subsequent processing. The exhaust gas from rare earth calcination furnaces is extremely hot, and direct discharge or transportation of it can cause multiple safety hazards. The high-temperature exhaust gas can burn operators, and if it comes into contact with flammable materials in the workshop, it can easily cause a fire or even an explosion. Cooling the exhaust gas can lower its temperature, thus avoiding thermal damage, fires, and other safety accidents, and ensuring the safety of workshop personnel and the continuity of production. In existing equipment, most can only cool high-temperature exhaust gas from a fixed position. However, the range of air cooling is extremely limited, which may result in insufficient cooling of the high-temperature exhaust gas during circulation, leading to very low cooling efficiency. Therefore, we propose a rapid cooling mechanism for exhaust gas from a rare earth incinerator. Utility Model Content

[0003] The purpose of this utility model is to provide a rapid cooling mechanism for exhaust gas in a rare earth incineration furnace. Through the cooling mechanism and the flow limiting mechanism, it solves the problem that most methods can only implement air cooling for high-temperature exhaust gas from a fixed position, but the range of air cooling is extremely limited, which may lead to the inability to ensure that the high-temperature exhaust gas is cooled sufficiently during the circulation process, resulting in very low cooling efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rapid cooling mechanism for exhaust gas from a rare earth incineration furnace, comprising a housing, wherein a plurality of support legs are fixedly connected to the bottom outer wall of the housing, and a cooling mechanism is provided on the inner wall of the housing. The cooling mechanism includes a fan, the outer wall of which is fixedly connected to the outer wall of the housing. A flexible hose is fixedly connected to the output end of the fan. A jet nozzle is fixedly connected to the outer wall of the end of the flexible hose away from the fan. The outer wall of the jet nozzle is rotatably connected to the inner wall of the housing. The jet nozzle penetrates the housing to the outer wall. A motor limiting block is fixedly connected to the outer wall of the housing. A dual-axis motor is fixedly connected to the outer wall of the motor limiting block. Several transmission rods are fixedly connected to the bottom output end of the dual-axis motor via a coupling. Each transmission rod has a transmission rod limiting block rotatably connected to its outer wall. The outer wall of the transmission rod limiting block is fixedly connected to the outer wall of the housing. The end of the transmission rod away from the dual-axis motor... A connecting rod is fixedly connected to the outer wall. A second connecting rod is rotatably connected to the outer wall of the first connecting rod. A bearing seat is rotatably connected to the outer wall of the second connecting rod. Several sliding rods are fixedly connected to the outer wall of the bearing seat. Sliding rod limiting blocks are slidably connected to the outer walls of the sliding rods. The sliding rods pass through the sliding rod limiting blocks to the outer wall. The outer wall of the sliding rod limiting blocks is fixedly connected to the outer wall of the housing. A slide rail is fixedly connected to the outer wall of the end of the sliding rods away from the bearing seat. Several convex shaft plates are fixedly connected to the outer wall of the jet head. The outer walls of the convex shaft plates are slidably connected to the inner wall of the slide rail. A water pump is fixedly connected to the inner wall of the housing. A drain pipe is fixedly connected to the bottom outer wall of the housing.

[0005] Furthermore, the inner wall of the housing is provided with a flow limiting mechanism, which includes an exhaust gas conveying pipe. The outer wall of the exhaust gas conveying pipe is fixedly connected to the inner wall of the housing. A flow limiting pipe is fixedly connected to the outer wall of the exhaust gas conveying pipe, and a worm gear limiting block is fixedly connected to the outer wall of the flow limiting pipe.

[0006] Furthermore, a worm is rotatably connected to the inner wall of the worm gear limiting block, and a knob is fixedly connected to the outer wall of the worm gear.

[0007] Furthermore, a worm gear is rotatably connected to the outer wall of the exhaust gas conveying pipe, the outer wall of the worm gear meshes with the outer wall of the worm, and a rotating ring is fixedly connected to the outer wall of the worm gear.

[0008] Furthermore, the inner wall of the rotating ring is rotatably connected to the outer wall of the flow-limiting tube, and a number of fixing rods are fixedly connected to the outer wall of the rotating ring.

[0009] Furthermore, the inner wall of the flow-limiting tube is rotatably connected to several rotating rods, which penetrate the flow-limiting tube to the outer wall, and the outer walls of the rotating rods are all fixedly connected to connecting blocks.

[0010] Furthermore, the outer wall of the connecting block is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a slide rail two, the inner wall of the slide rail two being slidably connected to the outer wall of the fixed rod.

[0011] Furthermore, a baffle is fixedly connected to the outer wall of the rotating rod, and a number of fixed blocks are rotatably connected to the outer walls of the rotating rod.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting a bearing seat, allows a dual-shaft motor to drive several transmission rods to rotate. Each transmission rod drives one end of a connecting rod to rotate, which in turn drives a second connecting rod to move back to its original position. This second connecting rod then drives the bearing seat to move back to its original position, which in turn drives several sliding rods to move back to their original position. These sliding rods then drive a slide rail to move back to its original position, which in turn drives a convex shaft plate to rotate back and forth. Finally, these convex shaft plates drive the jet nozzle to rotate back and forth. If the exhaust gas temperature is very high, simply starting the water pump will draw clean water into the chamber from an external water source pipe. This achieves sufficient and comprehensive air cooling for the high-temperature exhaust gas, ensuring thorough cooling during its circulation and greatly enhancing cooling efficiency.

[0013] 2. This utility model, by incorporating baffles, allows for the reduction of exhaust gas flow by simply turning a knob clockwise. The knob drives a worm gear, which in turn drives a worm wheel, which in turn drives a rotating ring. This rotating ring then drives several fixed rods to rotate around it. Since these fixed rods are slidably connected to the slide rail, they all cause the slide rail to rotate around the rotating rod. The slide rail then drives a rotating shaft, which in turn drives a connecting block. This connecting block then drives the rotating rod, which in turn drives the baffles. The simultaneous rotation of these baffles reduces the gaps between them, allowing for free adjustment of the flow rate based on the temperature of the high-temperature exhaust gas. This prevents the exhaust gas from being over-cooled due to excessive flow at once, further improving the reliability of the equipment.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A bearing seat 210 is rotatably connected to the outer wall of coupling rod 209. Transmission rod 206 mainly serves to fix and limit coupling rod 208. When transmission rod 206 rotates, it drives coupling rod 208 to rotate as well. Several sliding rods 211 are fixedly connected to the outer wall of bearing seat 210.

The exhaust gas conveying pipe 301 mainly limits the rotation of the worm wheel 306. The worm wheel 306 can only rotate in a fixed position on the exhaust gas conveying pipe 301.

[0021] The inner wall of the rotating ring 307 is rotatably connected to the outer wall of the flow-limiting tube 302. Several fixed rods 308 are fixedly connected to the outer wall of the rotating ring 307. Several rotating rods 309 are rotatably connected to the inner wall of the flow-limiting tube 302. The flow-limiting tube 302 mainly limits the rotation of the rotating rods 309, allowing them to rotate only at fixed positions within the flow-limiting tube 302. The rotating rods 309 penetrate the flow-limiting tube 302 to the outer wall. Connecting blocks 310 are fixedly connected to the outer walls of each rotating rod 309. The outer walls of the connecting blocks 310 are rotatably connected... A rotating shaft 311 is connected to a slide rail 312 fixedly connected to the outer wall of the rotating shaft 311. The rotating rod 309 mainly serves to fix and limit the connecting block 310. The connecting block 310 can only be fixed in a fixed position on the rotating rod 309. The inner wall of the slide rail 312 is slidably connected to the outer wall of the fixed rod 308. A baffle 313 is fixedly connected to the outer wall of the rotating rod 309. A fixed block 314 is rotatably connected to the outer walls of several rotating rods 309. The rotating rod 309 mainly serves to fix and limit the baffle 313. When the rotating rod 309 rotates, it will drive the baffle 313 to rotate together.

[0022] One specific application of this embodiment is: When staff need to use the equipment, first connect the flow-limiting pipe 302 to the exhaust gas pipe, then connect the exhaust gas delivery pipe 301 to the exhaust pipe, connect the input end of the water pump 215 to the water supply pipe, and connect the drain pipe 216 to the drain pipe. When high-temperature exhaust gas flows through the exhaust gas pipe, the exhaust gas needs to pass through the gaps of several baffles 313. The larger the gaps of the baffles 313, the more exhaust gas flows. To reduce the amount of exhaust gas flowing, simply turn the knob 305 clockwise. The knob 305 will drive the worm gear 304 to rotate, which in turn drives the worm wheel 306 to rotate. The worm wheel 306 will then drive the rotating ring 307. The rotating ring 307 drives several fixed rods 308 to rotate around it. Since the fixed rods 308 are all slidably connected to the slide rail 312, they all drive the slide rail 312 to rotate around the rotating rod 309. The slide rail 312 drives the rotating shaft 311 to rotate, which in turn drives the connecting block 310 to rotate. The connecting block 310 drives the rotating rod 309 to rotate, which in turn drives the baffle 313 to rotate. The baffles 313 rotate simultaneously to reduce the gaps between them. As the gaps decrease, the amount of exhaust gas passing through also decreases. The exhaust gas then enters the exhaust gas delivery pipe 30 through the flow restrictor 302. During the circulation process, if the exhaust gas temperature is not very high, simply start the fan 201 and the dual-shaft motor 205. The fan 201 will blow air from the outside into the hose 202, and the air will enter the nozzle 203 through the hose 202. The air will then be sprayed through the nozzle 203 into the exhaust gas delivery pipe 301 to cool the exhaust gas inside the pipe. During this process, the dual-shaft motor 205 will drive several transmission rods 206 to rotate, and each of the transmission rods 206 will drive one end of the connecting rod 208 to rotate. The connecting rod 208 will drive the second connecting rod 209 to move back to its original position, and the second connecting rod 209 will drive the bearing seat 210 to move back to its original position. When the shaft seat 210 moves, it will drive several sliding rods 211 to move back to the reset position. The sliding rods 211 will drive the slide rail 213 to move back to the reset position. The slide rail 213 will drive the convex shaft plate 214 to rotate back and forth. The convex shaft plate 214 will drive the jet head 203 to rotate back and forth. The jet head 203 will rotate back and forth while blowing air to expand the range and efficiency of air cooling. If the exhaust gas temperature is very high, the water pump 215 will be started. The water pump 215 will draw clean water from the external water source pipe into the housing 1 and submerge the exhaust gas delivery pipe. The clean water can directly cool the exhaust gas in the exhaust gas delivery pipe 301. During this process, the clean water will take away the heat and be discharged from the drain pipe 216.
