Description

Technical Field

[0001] This invention belongs to the field of calcination furnace technology, specifically relating to a high-temperature melting waste heat recovery device for radioactive waste residue. Background Technology

[0002] A calcining furnace is a thermal equipment used for high-temperature heat treatment of carbon raw materials. It is mainly used in steel smelting, specialty chemical production, catalyst production, rare metal recovery, and environmental improvement. This equipment removes volatile matter and moisture from raw materials through high-temperature treatment, using energy sources such as natural gas, oil, and electricity, to produce calcined materials with stable physicochemical properties.

[0003] However, the filter screen inside the recovery tank of the waste heat recovery equipment cannot be removed during use. Prolonged use will cause the filter screen to be damaged or accumulate a lot of dust, resulting in a decrease in heat recovery efficiency. It is necessary to design a detachable filter screen so that the staff can easily replace the damaged or dusty filter screen. At the same time, the connection between the air duct and the calcining furnace lacks a fixed structure. The connection is exposed to a large amount of hot air for a long time, which will lead to unstable connection and easy detachment of the interface. This is not conducive to ensuring the stable operation of waste heat recovery. Furthermore, the air duct lacks an air volume adjustment component, which cannot adjust the amount of hot air, which is not conducive to improving the waste heat recovery efficiency. Excessive air volume will accelerate the loss of waste heat, while insufficient air volume will reduce the efficiency of waste heat entering the recovery tank. It is necessary to design a structure with adjustable air volume so that the amount of air entering the recovery tank can be adjusted according to the amount of waste heat remaining.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figure 1-8 The present invention provides the following technical solution: a high-temperature melting waste heat recovery device for radioactive waste residue, comprising a calcining furnace body 100, a connecting component 300 at the upper end of the calcining furnace body 100, a gas guide pipe 110 at the upper end of the connecting component 300, a fan 120 fixedly connected to the surface of the gas guide pipe 110, an air volume regulating component 400 fixedly connected to one side of the surface of the gas guide pipe 110, a filter component 200 fixedly connected to one end of the gas guide pipe 110, a recovery tank 130 fixedly connected to the lower end of the filter component 200, a cylinder 140 fixedly connected inside the recovery tank 130, a liquid exchange pipe 150 provided inside the cylinder 140, and an exhaust pipe 160 fixedly connected to one side of the inside of the cylinder 140.

[0022] Specifically, the filter assembly 200 includes a mounting plate 210, a fixing box 220, a filter screen 230, a limiting mechanism 240, a limiting post 250, a pull plate 260, a rack 270, a gear 280, and a primary motor 290. The upper end of the recycling tank 130 is fixedly connected to the fixing box 220. The mounting plate 210 is slidably connected inside the fixing box 220. The filter screen 230 is slidably connected inside the mounting plate 210. The upper end of the filter screen 230 is provided with a limiting mechanism 240. One side of the mounting plate 210 is fixedly connected to a limiting post 250. The surface of the limiting post 250 is provided with a pull plate 260. One end of the pull plate 260 is fixedly connected to a rack 270. The lower end of the rack 270 is meshed with a gear 280. One side of the gear 280 is provided with a primary motor 290.

[0023] By adopting the above technical solution, when replacing the filter screen 230, the first motor 290 is started to drive the gear 280 to rotate. The gear 280 drives the rack 270 to move away from the fixed box 220. The rack 270 drives the limiting post 250 and the mounting plate 210 to move, so that the mounting plate 210 slides inside the fixed box 220. The mounting plate 210 drives the filter screen 230 to move, thereby removing the filter screen 230 from the fixed box 220. By using the limiting mechanism 240 to release the limitation on the filter screen 230, the filter screen 230 can be taken out.

[0024] Specifically, the limiting mechanism 240 includes a limiting plate 241, a spring 242, a fixing rod 243, and a fixing ring 244. The lower end of the filter screen 230 is provided with a fixing ring 244, the upper end of the filter screen 230 is provided with a limiting plate 241, the lower end of the limiting plate 241 is fixedly connected with a spring 242, and the fixing rod 243 is rotatably connected inside the limiting plate 241.

[0025] By adopting the above technical solution, when the limit on the filter screen 230 is released, the limit plate 241 is pulled upward to rotate around the fixed rod 243. At this time, the filter screen 230 can be pulled upward to disengage from the fixed ring 244, thereby removing the filter screen 230.

[0026] Specifically, a support block is fixedly connected to the upper end of the rack 270, and a limit rod is slidably connected to the upper end of the support block.

[0027] By adopting the above technical solution, when the rack 270 moves, the rack 270 drives the support block to slide along the limit rod, limiting the movement trajectory of the rack 270 and preventing the rack 270 from being misaligned with the gear 280 when it moves.

[0028] Specifically, a stop block is fixedly connected to one side of the rack 270, and a sealing gasket is fixedly connected to the surface of the mounting plate 210.

[0029] By adopting the above technical solution, when using the filter assembly 200, the stop block can prevent the rack 270 from disengaging from the gear 280 when it moves, and the sealing gasket can prevent hot air from flowing out from the gap between the mounting plate 210 and the fixing box 220.

[0030] In this embodiment, during use: Motor 290 is started, causing gear 280 to rotate. Gear 280 drives rack 270 to move away from the fixed box 220. Rack 270 drives limiting post 250 and mounting plate 210 to move, causing mounting plate 210 to slide inside fixed box 220. Mounting plate 210 drives filter screen 230 to move, thereby removing filter screen 230 from inside fixed box 220. By using limiting mechanism 240 to release the limitation on filter screen 230, filter screen 230 can be removed. Remove the filter screen 230 and pull the limiting plate 241 upward to make it rotate around the fixing rod 243. At this time, the filter screen 230 can be pulled upward to disengage it from the fixing ring 244, thereby removing the filter screen 230. The rack 270 drives the support block to slide along the limiting rod, limiting the movement trajectory of the rack 270 and preventing the rack 270 from misaligning with the gear 280 when it moves. The stop block can prevent the rack 270 from disengaging from the gear 280 when it moves. The sealing gasket can prevent hot air from flowing out from the gap between the mounting plate 210 and the fixing box 220.

[0031] Example 2 The difference between this embodiment and Embodiment 1 is that, specifically, the connecting assembly 300 includes a fixed plate 310, a bidirectional lead screw 320, a sliding block 330, a push plate 340, an insert block 350, a connecting frame 360, and a positioning mechanism 370. The fixed plate 310 is symmetrically arranged at the upper end of the calcining furnace body 100. The bidirectional lead screw 320 is rotatably connected inside the fixed plate 310. The sliding block 330 is symmetrically arranged on the surface of the bidirectional lead screw 320. The push plate 340 is fixedly connected to one side of the sliding block 330. The insert block 350 is symmetrically arranged on one side of the push plate 340. The connecting frame 360 ​​is slidably connected to the surface of the insert block 350. The positioning mechanism 370 is arranged on one side of the connecting frame 360.

[0032] By adopting the above technical solution, when fixing the gas guide pipe 110, the positions of the connecting frame 360 ​​and the push plate 340 are aligned by using the positioning mechanism 370. Then, the bidirectional screw 320 is rotated to drive the two sliding blocks 330 to move towards each other. The sliding blocks 330 drive the push plate 340 and the insert block 350 to move, so that the insert block 350 is inserted into the interior of the connecting frame 360, thereby fixing the interface between the gas guide pipe 110 and the calcining furnace body 100.

[0033] Specifically, the positioning mechanism 370 includes a positioning plate 371, a positioning frame 372, a rotating wheel 373, and a locking plate 374. The positioning plate 371 is fixedly connected to one side of the connecting frame 360, the locking plate 374 is fixedly connected to one side of the positioning plate 371, the positioning frame 372 is slidably connected to one side of the locking plate 374, and the rotating wheel 373 is rotatably connected inside the positioning frame 372.

[0034] By adopting the above technical solution, when aligning the connecting frame 360 ​​and the push plate 340, the positioning plate 371 is pushed downward to insert it into the interior of the positioning frame 372. Then, the positioning plate 371 is pushed downward, and the positioning plate 371 slides between the rotating wheels 373. The locking plate 374 restricts the positioning plate 371 so that it does not shift, until the positioning plate 371 falls to the bottom of the interior of the positioning frame 372. This allows the positioning plate 371 to drive the connecting frame 360 ​​to move and align it with the push plate 340.

[0035] Specifically, a limit ring is fixedly connected to one end of the bidirectional lead screw 320, and a turntable is fixedly connected to the other end of the bidirectional lead screw 320. Several protrusions are fixedly connected to the surface of the turntable.

[0036] By adopting the above technical solution, when the bidirectional lead screw 320 is rotated, the limiting ring can prevent the bidirectional lead screw 320 from dislodging from the interior of the fixed plate 310, the turntable can increase the contact area between the bidirectional lead screw 320 and the opponent, and the protrusion can increase the friction of the turntable against the opponent, making it easier for the operator to rotate the bidirectional lead screw 320.

[0037] Specifically, the lower end of the pusher plate 340 is fixedly connected to a sliding plate, and the upper end of the calcining furnace body 100 is symmetrically provided with sliding grooves, and the sliding plate and the sliding grooves are slidably connected.

[0038] By adopting the above technical solution, when using the connecting component 300, the push plate 340 drives the slide plate to slide inside the slide groove, which can prevent the push plate 340 from tilting when it moves, making it difficult for the insert block 350 to be inserted into the connecting frame 360.

[0039] In this embodiment, during use: the positioning mechanism 370 aligns the positions of the connecting frame 360 ​​and the push plate 340. Then, the bidirectional lead screw 320 is rotated to move the two sliding blocks 330 towards each other. The sliding blocks 330 move the push plate 340 and the insert block 350, causing the insert block 350 to insert into the connecting frame 360, thereby fixing the interface between the gas pipe 110 and the calcining furnace body 100. The positioning plate 371 is then pushed downwards to insert into the positioning frame 372. The positioning plate 371 continues to slide downwards between the rotating wheels 373, and the locking plate 374 restricts the positioning. The positioning plate 371 prevents it from shifting until it falls to the bottom of the inner part of the positioning frame 372. This allows the positioning plate 371 to move the connecting frame 360 ​​and align it with the push plate 340. The limiting ring prevents the bidirectional lead screw 320 from disengaging from the inside of the fixed plate 310 when it rotates. The turntable increases the contact area between the bidirectional lead screw 320 and the opponent. The protrusion increases the friction of the turntable against the opponent, making it easier for the operator to rotate the bidirectional lead screw 320. The push plate 340 drives the slide plate to slide inside the groove, preventing the push plate 340 from tilting when it moves, which would make it difficult for the insert block 350 to be inserted into the inside of the connecting frame 360.

[0040] Example 2 The difference between this embodiment and embodiments 1 and 2 is that, specifically, the air volume regulating component 400 includes a housing 410, a ventilation plate 420, a baffle 430, a hinge seat 440, a rotating plate 450, a movable plate 460, a screw 470, and a second motor 480. The housing 410 is fixedly connected to the surface of the air duct 110. The ventilation plate 420 is fixedly connected to the inside of the housing 410. The baffle 430 is slidably connected to one side of the ventilation plate 420. The hinge seat 440 is symmetrically arranged on one side of the baffle 430. The rotating plate 450 is rotatably connected to the surface of the hinge seat 440. The movable plate 460 is rotatably connected to one end of the rotating plate 450. The screw 470 is threadedly connected to the inside of the movable plate 460. The second motor 480 is provided at one end of the screw 470.

[0041] By adopting the above technical solution, when adjusting the air volume, the second motor 480 is started to drive the screw 470 to rotate. The screw 470 drives the movable plate 460 to move left and right. The movable plate 460 drives the rotating plate 450 to move. At the same time, the rotating plate 450 rotates around the movable plate 460, thereby causing the rotating plate 450 to drive the hinge seat 440 and the baffle 430 to move up and down. The area of ​​the baffle 430 blocking the ventilation plate 420 changes, thereby increasing or decreasing the area of ​​hot air passing through the ventilation plate 420, thus realizing the adjustment of the air volume.

[0042] In this embodiment, when in use: the second motor 480 is started to drive the screw 470 to rotate. The screw 470 drives the movable plate 460 to move left and right. The movable plate 460 drives the rotating plate 450 to move. At the same time, the rotating plate 450 rotates around the movable plate 460, thereby causing the rotating plate 450 to drive the hinge seat 440 and the baffle 430 to move up and down. The area of ​​the baffle 430 blocking the ventilation plate 420 changes, thereby increasing or decreasing the area of ​​hot air passing through the ventilation plate 420, thus achieving the adjustment of the air volume.

[0043] In this invention, the No. 1 motor 290 is a publicly available technology, and the selected model is RS-540SH-1.

[0044] In this invention, the No. 2 motor 480 is a publicly available technology, and the selected model is JGB37-520.

[0045] The working principle and usage process of this invention: When using the high-temperature melting waste heat recovery equipment for radioactive waste residue, start motor 290 to drive gear 280 to rotate. Gear 280 drives rack 270 to move away from fixed box 220. Rack 270 drives limit post 250 and mounting plate 210 to move, causing mounting plate 210 to slide inside fixed box 220. Mounting plate 210 drives filter screen 230 to move, thereby removing filter screen 230 from inside fixed box 220. By using limit mechanism 240 to release the limit on filter screen 230, filter screen 230 can be taken out. Pull limit plate 241 upward to make it rotate around fixed rod 243. At this time, filter screen 230 can be pulled upward. 0. Disengage it from the retaining ring 244, thereby removing the filter screen 230. The rack 270 drives the support block to slide along the limiting rod, limiting the movement trajectory of the rack 270 and preventing misalignment between the rack 270 and the gear 280 during movement. The stop block prevents the rack 270 from disengaging from the gear 280 during movement. The sealing gasket prevents hot air from leaking out from the gap between the mounting plate 210 and the fixing box 220. Align the positions of the connecting frame 360 ​​and the push plate 340 using the positioning mechanism 370. Then, rotate the bidirectional lead screw 320 to drive the two sliding blocks 330 to move towards each other. The sliding blocks 330 drive the push plate 340 and the insert block 350 to move, allowing the insert block 350 to insert into the inner part of the connecting frame 360. The interface between the gas guide pipe 110 and the calcining furnace body 100 is fixed. The positioning plate 371 is pushed down to insert into the positioning frame 372. The positioning plate 371 is then pushed down and slides between the rotating wheels 373. The locking plate 374 restricts the positioning plate 371 to prevent it from shifting until the positioning plate 371 falls to the bottom of the positioning frame 372. This allows the positioning plate 371 to move the connecting frame 360 ​​and align it with the push plate 340. The limiting ring prevents the bidirectional lead screw 320 from dislodging from the fixed plate 310 when it rotates. The turntable increases the contact area between the bidirectional lead screw 320 and the opponent, and the protrusion increases the friction of the turntable against the opponent, facilitating operation. The operator rotates the bidirectional lead screw 320, which causes the push plate 340 to slide inside the slide groove, preventing the push plate 340 from tilting during movement and making it difficult for the insert block 350 to be inserted into the connecting frame 360. The second motor 480 is started to drive the screw 470 to rotate. The screw 470 drives the movable plate 460 to move left and right. The movable plate 460 drives the rotating plate 450 to move. At the same time, the rotating plate 450 rotates around the movable plate 460, which causes the rotating plate 450 to drive the hinge seat 440 and the baffle 430 to move up and down. The area of ​​the baffle 430 blocking the ventilation plate 420 changes, thereby increasing or decreasing the area through which hot air passes through the ventilation plate 420, thus adjusting the air volume.
