Description

Technical Field

[0001] This invention relates to the technical field of waste heat utilization equipment for lead-antimony alloy smelting flue gas, specifically a waste heat utilization device for lead-antimony alloy smelting flue gas. Background Technology

[0002] Waste heat recovery devices are industrial energy-saving equipment mainly used to recover the waste heat carried in the high-temperature flue gas emitted by equipment such as boilers, kilns, and incinerators, and convert it into reusable thermal energy, thereby reducing energy consumption, reducing carbon emissions, and improving resource utilization efficiency.

[0003] In existing technologies, flue gas is generated during the smelting of lead-antimony alloys. Since the flue gas contains impurities, it is necessary to filter these impurities during the collection of waste heat from the flue gas. Currently, this is done using a filter disc. As the filter disc is used for a long time, impurities accumulate. To prevent the filter disc from clogging, the staff needs to clean it regularly. The cleaning process requires disassembling the filter disc and then reinstalling it after cleaning. This disassembly and reinstallation process is cumbersome and reduces the efficiency of waste heat collection from the flue gas. Summary of the Invention

[0013] Furthermore, the vibration mechanism includes a support column, the surface of which is provided with a sliding groove, and a sliding ring is slidably connected to the inner wall of the sliding groove. A return spring and a driven ring are fixedly connected to the surface of the sliding ring. A force-bearing inclined block is fixedly connected to the side of the sliding ring away from the return spring. A fixed plate is fixedly connected to the end of the support column, and a pressing rod is fixedly connected to the surface of the filter rotating plate.

[0014] Furthermore, the bottom of the support column is fixedly connected to the surface of the filter disc, the surface of the slide bar is fixedly connected to the surface of the fixed disc, the end of the push plate away from the impact slide plate is hinged to the surface of the driven ring, and the inner wall of the driven ring is in contact with the surface of the support column.

[0015] Furthermore, the storage mechanism includes a push rod, a push ring is fixedly connected to the end of the push rod, a bent rod is fixedly connected to the bottom of the push ring, a reciprocating push rod is hinged to the end of the bent rod away from the push ring, and a storage tray is slidably connected to the inner wall of the filter cylinder.

[0016] Furthermore, the end of the lower push rod away from the lower push ring is fixedly connected to the surface of the driven ring, the end of the bent rod near the reciprocating push rod and penetrating the surface of the filter disc is hinged to the end of the reciprocating push rod, the end of the reciprocating push rod away from the bent rod is hinged to the surface of the material pushing shrink ring, the bottom of the material pushing shrink ring and the sealing shrink ring are both in contact with the surface of the receiving ring, the top of the sealing shrink ring is in contact with the bottom of the filter disc, the inner wall of the filter cylinder is provided with a groove, and the surface of the reciprocating push rod is slidably connected to the inner wall of the groove.

[0017] The present invention has the following beneficial effects:

[0018] This invention employs a filtration mechanism. First, a combustion boiler is started to burn a lead-antimony alloy. The resulting flue gas enters the filter cylinder through an exhaust pipe. Then, a motor drives a geared disc to rotate. As the disc rotates, a geared ring slides annularly against the inner wall of the filter cylinder. This sliding ring drives a rotating rod, which in turn rotates a filter plate. The rotating filter plate captures impurities from the flue gas, trapping them on its surface. Simultaneously, as the flue gas moves downwards, it passes over the surface of the filter plate, where impurities are filtered out. Finally, the residual heat from the flue gas enters a collection bin and is collected inside. When reusing waste heat from flue gas, the one-way valve can be opened to allow the waste heat to be discharged through the flue pipe and to a designated location, thus achieving the effect of utilizing waste heat. Simultaneously, the rotating filter plate drives the scraper to rotate, which in turn drives the surface of the filter disc. The centrifugal force from the rotating scraper throws impurities onto the surface of the receiving ring, preventing clogging of the filter disc. This effectively filters impurities in the flue gas through the simultaneous use of the rotating filter plate and the filter disc, improving filtration efficiency. Furthermore, the rotating scraper cleans the surface of the filter disc, preventing clogging and improving the efficiency of waste heat collection.

[0019] This invention utilizes a vibration mechanism. As the filter plate rotates, it drives the extrusion rod to rotate. During this rotation, the extrusion rod contacts the surface of the force-bearing inclined block and compresses it. When the force-bearing inclined block is compressed, it pushes two slip rings to slide away from each other along the inner wall of the groove. This sliding motion of the slip rings pushes the return spring to contract away from each other, and simultaneously pushes two driven rings to move away from each other. The movement of the driven rings pushes the end of the push plate away from each other, while the other end of the push plate pushes the impact slide plate to slide away from each other along the inner wall of the groove rod. Simultaneously, when the impact slide plate reaches its final position, the filter plate rotates to the same position as the impact slide plate, and the end of the impact slide plate impacts the surface of the filter plate. This process, involving the extrusion rod and the force-bearing inclined block, creates a powerful impact. When the inclined blocks finish pressing, the slip ring will return to its original position via the return spring, and the driven ring will also return to its original position along with the slip ring. At the same time, it will pull the impact plate and push plate back to their original positions. Since there are several force-bearing inclined blocks, as the filter rotating plate drives the extrusion rod to keep rotating, the extrusion rod will continuously extrude force-bearing inclined blocks, thereby causing the push plate to circulate and impact the filter rotating plate, causing the filter rotating plate to vibrate and vibrate the impurities on the surface of the filter rotating plate to fall onto the surface of the filter disc. Then, the scraper will collect and throw them onto the surface of the receiving ring. Effectively, the impact plate continuously impacts the filter rotating plate, causing the filter rotating plate to vibrate and vibrate the impurities on the surface of the filter rotating plate to fall off, preventing the filter rotating plate from becoming clogged, thereby improving the efficiency of filtering impurities in the flue gas.

[0020] This invention employs a receiving mechanism. When the driven ring moves, it pushes the lower push rod downwards. The lower push rod then pushes the lower push ring downwards, which in turn pushes the bent rod downwards. Simultaneously, the other end of the bent rod slides downwards along the inner wall of the groove. As the bent rod slides downwards, it pulls the end of the reciprocating push rod downwards. The other end of the reciprocating push rod then pushes the material-pushing shrinking rings to retract in a direction closer to each other. During the retraction of the material-pushing shrinking rings, impurities on the surface of the receiving rings are pushed to retract in a direction closer to each other. The retraction of the material-pushing shrinking rings also pushes the driven rod to retract in a direction closer to each other. As the driven rod moves, it pushes the sealing shrinking rings to retract in a direction closer to each other. During the retraction of the sealing shrinking rings, they separate from the surface of the receiving rings. During the shrinking process, the pusher shrink ring moves to the edge of the receiving ring surface and pushes impurities from the receiving ring surface into the inside of the receiving tray. When the driven ring resets, it pulls the lower push rod upward, which in turn pulls the lower push ring and the bent rod upward to reset. At the same time, the reciprocating push rod resets along with the bent rod. When the reciprocating push rod resets, it pulls the pusher shrink ring, the driven rod, and the sealing shrink ring to reset. Since the driven ring continues to move up and down reciprocally, the pusher shrink ring pushes the sealing shrink ring through the driven rod to maintain a cyclical expansion and contraction. After the sealing shrink ring resets to its original position, it plays a sealing role. By effectively maintaining a cyclical expansion and contraction through the pusher shrink ring, impurities on the receiving ring surface can be continuously cleaned and collected inside the receiving tray.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0035] 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.

[0036] Please see Figures 1-10 As shown, the present invention is a waste heat utilization device for lead-antimony alloy smelting flue gas, including a support frame 1, a combustion boiler 2 and a filter cylinder 3 fixedly connected to the inner wall of the support frame 1, a flue pipe 4 fixedly connected to the top of the combustion boiler 2, a sealing door 5 hinged to the inner wall of the combustion boiler 2, a motor 6 fixedly connected to the surface of the filter cylinder 3, a collection bucket 7 fixedly connected to the bottom of the filter cylinder 3, and a flue pipe 8 fixedly connected to the surface of the collection bucket 7. The invention is characterized by further comprising:

[0037] The filter mechanism 10 includes a receiving ring 15, a right-angle rod 16 is fixedly connected to the inner wall of the receiving ring 15, and a filter disc 17 is fixedly connected to the end of the right-angle rod 16 away from the receiving ring 15.

[0038] The vibration mechanism 30 includes a slide bar 37, an impact slide plate 38 is slidably connected to the inner wall of the slide bar 37, and a push plate 39 is hinged to the surface of the impact slide plate 38.

[0039] The storage mechanism 50 includes a pusher shrink ring 55, a driven rod 56 is fixedly connected to the inner wall of the pusher shrink ring 55, and a sealing shrink ring 57 is fixedly connected to the end of the pusher shrink ring 55 away from the pusher shrink ring 55.

[0040] The end of the flue pipe 4 furthest from the combustion boiler 2 is fixedly connected to the top of the filter cylinder 3. Both ends of the flue pipe 4 are connected to the inner walls of the combustion boiler 2 and the filter cylinder 3. A one-way valve is provided on the surface of the flue pipe 8. The bottom of the collection bucket 7 is fixedly connected to the surface of the support frame 1.

[0041] The filter mechanism 10 includes a toothed ring 11, a rotating rod 12 fixedly connected to the inner wall of the toothed ring 11, a filter rotating plate 13 fixedly connected to the end of the rotating rod 12 away from the toothed ring 11, a scraper 14 fixedly connected to the bottom of the filter rotating plate 13, and a toothed disc 18 fixedly connected to the output end of the motor 6. First, the combustion boiler 2 is started to burn the lead-antimony alloy, and the flue gas produced by the combustion enters the interior of the filter cylinder 3 through the exhaust pipe 4. At this time, the motor 6 is started to drive the toothed disc 18 to rotate. When the toothed disc 18 rotates, it causes the toothed ring 11 to slide in a ring on the inner wall of the filter cylinder 3. The sliding of the toothed ring 11 drives the rotating rod 12 to rotate. When rod 12 rotates, it drives filter plate 13 to rotate. As filter plate 13 rotates, it captures impurities in the flue gas, which are then captured on the surface of filter plate 13. At the same time, as the flue gas moves downward, it passes through the surface of filter disc 17, and the impurities in the flue gas are filtered and placed on the surface of filter disc 17. Finally, the waste heat of the flue gas enters the interior of collection tank 7 and is collected inside the collection tank 7. When the waste heat of the flue gas is reused, the one-way valve can be opened to allow the waste heat of the flue gas to be discharged through the flue gas outlet pipe 8, thereby achieving the effect of utilizing the waste heat of the flue gas.

[0042] The surface of the toothed ring 11 is slidably connected to the top of the inner wall of the filter cylinder 3. The toothed ring 11 meshes with the toothed disc 18. The bottom of the scraper 14 contacts the surface of the filter disc 17. The outer wall of the receiving ring 15 is fixedly connected to the inner wall of the filter cylinder 3. When the filter rotating plate 13 rotates, it will drive the scraper 14 to rotate. When the scraper 14 rotates, it will drive the surface of the filter disc 17 to rotate. Then, the centrifugal force of the rotating scraper 14 will throw the impurities onto the surface of the receiving ring 15, thereby preventing the filter disc 17 from becoming clogged. The filter rotating plate 13 and the filter disc 17 can effectively filter the impurities in the flue gas at the same time, thereby improving the filtration efficiency. Then, the scraper 14 will clean the impurities on the surface of the filter disc 17 by rotating, thereby preventing the accumulation of impurities on the surface of the filter disc 17 from becoming clogged, and improving the efficiency of collecting waste heat from the flue gas.

[0043] The vibration mechanism 30 includes a support column 31. A groove is formed on the surface of the support column 31, and a slip ring 32 is slidably connected to the inner wall of the groove. A return spring 33 and a driven ring 34 are fixedly connected to the surface of each slip ring 32. A force-bearing inclined block 35 is fixedly connected to the side of the slip ring 32 away from the return spring 33. A fixed disk 36 is fixedly connected to the end of the support column 31. A pressing rod 40 is fixedly connected to the surface of the filter rotating plate 13. When the filter rotating plate 13 rotates, it drives the pressing rod 40 to rotate. During the rotation of the pressing rod 40, it contacts the surface of the force-bearing inclined block 35 and presses the force-bearing inclined block 35. When the force-bearing inclined block 35 is pressed, it pushes... The two sliding rings 32 slide in a direction away from each other on the inner wall of the slide groove. When the sliding rings 32 slide, they push the return spring 33 to contract in a direction away from each other, and at the same time push the two driven rings 34 to move in a direction away from each other. When the driven rings 34 move, they push the end of the push plate 39 to move in a direction away from each other. The other end of the push plate 39 pushes the impact slide plate 38 to slide in a direction away from each other on the inner wall of the slide groove rod 37. When the impact slide plate 38 slides into place, the filter rotating plate 13 rotates to the same position as the impact slide plate 38. The end of the impact slide plate 38 will impact the surface of the filter rotating plate 13.

[0044] The bottom of the support column 31 is fixedly connected to the surface of the filter plate 17, the surface of the sliding rod 37 is fixedly connected to the surface of the fixed plate 36, and the end of the push plate 39 away from the impact slide plate 38 is hinged to the surface of the driven ring 34. The inner wall of the driven ring 34 is in contact with the surface of the support column 31. When the extrusion rod 40 and the force-bearing inclined block 35 finish extruding, the slip ring 32 will return to its original position through the return spring 33, and the driven ring 34 will also return to its original position along with the slip ring 32. At the same time, it will also pull the impact slide plate 38 and the push plate 39 to return to their original positions. Since there are several force-bearing inclined blocks 35, when the filter rotating plate 13 drives the extrusion rod 40 While rotating continuously, the extrusion rod 40 continuously extrudes the force-bearing inclined block 35, causing the push plate 39 to cyclically impact the filter rotating plate 13. This causes the filter rotating plate 13 to vibrate, and impurities on the surface of the filter rotating plate 13 are vibrated off onto the surface of the filter disc 17. Then, the scraper 14 collects and throws the impurities onto the surface of the receiving ring 15. Effectively, the impact slide plate 38 continuously impacts the filter rotating plate 13, causing it to vibrate and dislodging impurities from its surface. This prevents the filter rotating plate 13 from becoming clogged, thereby improving the efficiency of filtering impurities in the flue gas.

[0045] The storage mechanism 50 includes a push rod 51, with a push ring 52 fixedly connected to the end of the push rod 51. A bent rod 53 is fixedly connected to the bottom of the push ring 52. A reciprocating push rod 54 is hinged to the end of the bent rod 53 away from the push ring 52. A storage tray 58 is slidably connected to the inner wall of the filter cartridge 3. When the driven ring 34 moves, it pushes the push rod 51 downward. When the push rod 51 moves, it pushes the push ring 52 downward. When the push ring 52 moves, it pushes the bent rod 53 downward. At the same time, the other end of the bent rod 53 slides downward on the inner wall of the groove. When the bent rod 53 moves downward, it pulls the end of the reciprocating push rod 54 downward. The other end of the reciprocating push rod 54 pushes the pusher shrink ring 55 to shrink towards each other. During the shrinking process of the pusher shrink ring 55, it pushes the impurities on the surface of the receiving ring 15 to move towards each other. When the pusher shrink ring 55 shrinks, it pushes the driven rod 56 to move towards each other. When the driven rod 56 moves, it pushes the sealing shrink ring 57 to shrink towards each other. During the shrinking process of the sealing shrink ring 57, it separates from the surface of the receiving ring 15. During the shrinking process, the pusher shrink ring 55 moves to the edge of the surface of the receiving ring 15 and pushes the impurities on the surface of the receiving ring 15 into the interior of the receiving tray 58.

[0046] The end of the lower push rod 51 away from the lower push ring 52 is fixedly connected to the surface of the driven ring 34. The bent rod 53 is close to one end of the reciprocating push rod 54 and passes through the surface of the filter disc 17, and is hinged to the end of the reciprocating push rod 54. The end of the reciprocating push rod 54 away from the bent rod 53 is hinged to the surface of the material pushing shrink ring 55. The bottoms of the material pushing shrink ring 55 and the sealing shrink ring 57 are in contact with the surface of the receiving ring 15. The top of the sealing shrink ring 57 is in contact with the bottom of the filter disc 17. A groove is provided on the inner wall of the filter cylinder 3. The surface of the reciprocating push rod 54 is slidably connected to the inner wall of the groove. When the driven ring 34 is reset, it will pull the lower push rod 51 to move upward. 51 will pull the lower push ring 52 and the bent rod 53 to reset upwards. At the same time, the reciprocating push rod 54 will reset along with the bent rod 53. When the reciprocating push rod 54 resets, it will pull the push shrink ring 55, the driven rod 56 and the sealing shrink ring 57 to reset. Since the driven ring 34 will continue to move up and down reciprocally, the push shrink ring 55 will push the sealing shrink ring 57 through the driven rod 56 to maintain a cyclic expansion and contraction. After the sealing shrink ring 57 resets to its original position, it will play a sealing role. By effectively maintaining a cyclic expansion and contraction through the push shrink ring 55, impurities on the surface of the receiving ring 15 can be continuously cleaned and stored inside the receiving tray 58.

[0047] In operation, the combustion boiler 2 is first started to burn the lead-antimony alloy. The flue gas produced by the combustion enters the interior of the filter cylinder 3 through the exhaust pipe 4. At this time, the motor 6 is started to drive the gear disc 18 to rotate. When the gear disc 18 rotates, it drives the gear ring 11 to slide in a ring on the inner wall of the filter cylinder 3. When the gear ring 11 slides, it drives the rotating rod 12 to rotate. When the rotating rod 12 rotates, it drives the filter plate 13 to rotate. When the filter plate 13 rotates, it captures impurities in the flue gas, thereby capturing the impurities on the surface of the filter plate 13. At the same time, when the flue gas moves downward, it passes through the surface of the filter disc 17, and the impurities in the flue gas are filtered through the filter disc 17 and placed on the surface of the filter disc 17. Finally, the residual heat of the flue gas enters the interior of the collection tank 7 and is finally collected. Inside the barrel 7, when reusing the waste heat of the flue gas, the one-way valve can be opened to allow the waste heat of the flue gas to be discharged through the flue pipe 8 and discharged to a designated location, thereby achieving the effect of utilizing the waste heat of the flue gas. While the filter plate 13 rotates, it drives the scraper 14 to rotate. The rotation of the scraper 14 drives the surface of the filter disc 17 to rotate, and the centrifugal force of the rotating scraper 14 throws impurities onto the surface of the receiving ring 15, thus preventing clogging of the filter disc 17. The rotation of the filter plate 13 also drives the extrusion rod 40 to rotate. During the rotation of the extrusion rod 40, it contacts the surface of the force-bearing inclined block 35 and extrudes it. When the force-bearing inclined block 35 is extruded, it pushes the two slip rings 32 against the inner wall of the chute. As the slip ring 32 slides, it pushes the return spring 33 to contract in a direction away from each other. Simultaneously, it pushes the two driven rings 34 to move in a direction away from each other. As the driven rings 34 move, they push the end of the push plate 39 to move in a direction away from each other. The other end of the push plate 39 pushes the impact slide plate 38 to slide against the inner wall of the slide bar 37 in a direction away from each other. When the impact slide plate 38 reaches its position, the filter rotating plate 13 rotates to the same position as the impact slide plate 38. The end of the impact slide plate 38 impacts the surface of the filter rotating plate 13. When the extrusion rod 40 and the force-bearing inclined block 35 finish extruding, the slip ring 32 returns to its original position via the return spring 33, and the driven rings 34 also... As the slip ring 32 returns to its original position, it also pulls the impact slide plate 38 and push plate 39 back to their original positions. Since there are several force-bearing inclined blocks 35, as the filter rotating plate 13 drives the extrusion rod 40 to rotate continuously, the extrusion rod 40 continuously extrudes the force-bearing inclined blocks 35, causing the push plate 39 to cyclically impact the filter rotating plate 13. This causes the filter rotating plate 13 to vibrate, and impurities on the surface of the filter rotating plate 13 are vibrated and fall onto the surface of the filter disc 17. These impurities are then collected by the scraper 14 and thrown onto the surface of the receiving ring 15. When the driven ring 34 moves, it pushes the lower push rod 51 downwards. When the lower push rod 51 moves, it pushes the lower push ring 52 downwards. When the lower push ring 52 moves, it pushes the bent rod 53 downwards.Simultaneously, the other end of the bent rod 53 slides downwards along the inner wall of the groove. As the bent rod 53 moves downwards, it pulls the end of the reciprocating push rod 54 downwards. The other end of the reciprocating push rod 54 pushes the material-pushing shrinking ring 55 to retract towards each other. During the retraction of the material-pushing shrinking ring 55, it pushes impurities on the surface of the receiving ring 15 towards each other. The retraction of the material-pushing shrinking ring 55 also pushes the driven rod 56 towards each other. As the driven rod 56 moves, it pushes the sealing shrinking ring 57 towards each other. During the retraction of the sealing shrinking ring 57, it separates from the surface of the receiving ring 15. Meanwhile, the material-pushing shrinking ring 55, during its retraction... During the process, it moves to the edge of the receiving ring 15 and pushes impurities from the surface of the receiving ring 15 into the inside of the receiving tray 58. When the driven ring 34 resets, it pulls the lower push rod 51 upward, and the lower push rod 51 pulls the lower push ring 52 and the bent rod 53 upward to reset. At the same time, the reciprocating push rod 54 resets along with the bent rod 53. When the reciprocating push rod 54 resets, it pulls the pushing shrink ring 55, the driven rod 56, and the sealing shrink ring 57 to reset. Since the driven ring 34 continues to move up and down reciprocally, the pushing shrink ring 55 pushes the sealing shrink ring 57 through the driven rod 56 to maintain a cyclical expansion and contraction. After the sealing shrink ring 57 resets to its original position, it will play a sealing role.
