Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste treatment and energy recovery, and particularly relates to a connecting structure of a incinerator and a boiler. BACKGROUND

[0002] In the connecting structure of the incinerator and the boiler, the exhaust gas pipeline plays a crucial role. It is not only responsible for effectively transporting the high-temperature flue gas generated by the incinerator to the boiler, but also ensures that the heat in the flue gas is fully utilized, improving the energy efficiency of the entire system. However, due to the presence of a large amount of particulate matter and ash in the flue gas, it is easy to cause the accumulation of the exhaust gas pipeline, thereby causing the problem of blockage.

[0003] The existing technology for handling the blockage phenomenon of the exhaust gas pipeline usually installs a mechanical or pneumatic ash removal device at the key position of the exhaust gas pipeline, or sprays a chemical cleaning agent into the exhaust gas pipeline to dissolve and remove the ash attached to the pipe wall.

[0004] However, in actual use, although the installation of a mechanical or pneumatic method can alleviate the blockage problem to a certain extent, it requires an additional power source and a complex control system, increasing the cost and maintenance difficulty of the equipment. Although the spraying of a chemical cleaning agent has a significant effect, the corrosion of the chemical substances is relatively strong, and long-term use may damage the pipe material and shorten its service life. Therefore, these methods mostly rely on external auxiliary facilities, increasing the operating cost and requiring frequent manual intervention for cleaning the pipeline, making the process more complex and increasing the labor cost. Therefore, the present application provides a connecting structure of a incinerator and a boiler. Practical new type content

[0005] The present application aims to solve the problem that the existing technology mostly relies on external auxiliary facilities, increases the operating cost, and requires frequent manual intervention for cleaning the pipeline. The present application provides a connecting structure of a incinerator and a boiler.

[0006] The present application specifically adopts the following technical solutions to achieve the above-mentioned purposes:

[0007] The utility model provides a kind of incinerator and boiler connecting structure, including exhaust flue one, one end of the exhaust flue one is fixedly connected with incinerator bottom, the other end of the exhaust flue one is fixedly connected with bending portion, the bending portion is inverted U shape, the bending portion is fixedly connected with exhaust flue two away from the one end of exhaust flue one, the other end of the exhaust flue two is fixedly connected with boiler air inlet, the bottom of the bending portion is equipped with dust outlet, the bottom of the bending portion is fixedly connected with collecting hopper, the bottom of the collecting hopper is fixedly connected with discharge box, the bottom of the discharge box is hinged with baffle, one side of the discharge box is fixedly connected with controller, through groove is equipped in the inside of the collecting hopper, collecting assembly is installed in the inside of the collecting hopper, filter assembly is staggeredly installed in the inside of the bending portion.

[0008] By adopting the above technical scheme, when the high-temperature gas generated by the incinerator enters the inside of the exhaust flue one, it will first pass through the bending portion and then enter the boiler through the exhaust flue two. The inverted U-shaped bending portion can accelerate the propagation speed of the flue gas and generate a strong centrifugal force, so that the soot in the flue gas is completely separated from the high-temperature gas. Then the soot slowly slides into the collecting assembly in the collecting hopper at the bottom of the bending portion for collection. Therefore, without using mechanical equipment and manual injection intervention, most of the soot can be effectively captured and collected, reducing the accumulation of soot in the exhaust pipe, thereby prolonging the cleaning cycle of the pipe and improving the overall operation efficiency of the pipe.

[0010] By adopting the above technical scheme, the bending portion can be stably connected with the exhaust flue one and the exhaust flue two through the flange plates one and the flange plates two. The sealing effect of the connecting portions can be improved through the sealing rings, reducing the leakage of soot.

[0012] By adopting the technical scheme, the motor is started to run, so that the collecting cavity gradually changes from the opening upward to the opening downward, and according to the influence of gravity, the smoke dust in the collecting cavity is discharged to the outside through the discharge box, so as to periodically clean the soot in the collecting assembly, and the maintenance process is greatly simplified.

[0013] Further, the filter assembly comprises a plurality of sliding rails fixedly connected to the inner wall of the bent portion, a through hole is formed through one side of the bent portion, a sealing plate is slidably connected in the through hole, a connecting plate is fixedly connected to one side of the sealing plate, a filter plate is clamped to the other side of the sealing plate, the filter plate is slidably connected in the sliding rail, and a clamping piece is mounted on one side of the sealing plate.

[0014] By adopting the technical scheme, the gas after preliminary separation continues to advance, and at this time, the gas passes through the filter plates arranged in staggered mode one by one, and the filter plates can filter and separate the smoke dust in the flue gas again.

[0015] Further, the clamping piece comprises a fixed block fixedly connected to one side of the sealing plate, a groove is formed in the top of the fixed block, a spring is fixedly connected in the groove, a clamping block is slidably connected in the groove, one end of the spring is fixedly connected to one end of the clamping block, a slot is formed in one side of the filter plate, and a clamping groove is formed in the top of the slot.

[0016] By adopting the technical scheme, one end of the clamping block is manually extruded to push it into the inside of the fixed block, so that the clamping block is separated from the clamping groove, at this time, the sealing plate can be pulled to drive the spring to be pulled out from the inside of the slot, so as to quickly replace the filter plate.

[0017] Further, one side of the discharge box is fixedly connected with a first fixed plate, one side of the baffle is fixedly connected with a second fixed plate, the bottom of the first fixed plate is fixedly connected with a second magnetic block, and the top of the second fixed plate is fixedly connected with a first magnetic block.

[0018] By adopting the technical scheme, the baffle is pulled to separate the second magnetic block from the first magnetic block, so as to open the baffle.

[0019] Further, the smoke exhaust duct one and the smoke exhaust duct two are made of stainless steel, and the bent portion is made of carbon steel.

[0020] By adopting the technical scheme, the smoke exhaust duct one and the smoke exhaust duct two made of stainless steel can have good high-temperature resistance and corrosion resistance.

[0021] Further, the surface of the bent portion is provided with an anti-rust layer, and the anti-rust layer is a zinc-plated film.

[0022] By adopting the above technical scheme, the durability and corrosion resistance of the bending part can be effectively improved by spraying the zinc film on the surface of the bending part, and the long-term stable operation of the equipment is effectively maintained.

[0036] In use, when the high-temperature gas generated by the incinerator enters the inside of the smoke exhaust pipe 1, the high-temperature gas will first pass through the inside of the bent part 2 and then enter the boiler through the smoke exhaust pipe 3, and when the high-temperature gas carrying the soot passes through the bent part 2, the high-temperature gas will first collide with the inner wall of the bent part 2, and due to the inverted U-shaped design of the bent part 2, the propagation speed of the flue gas can be accelerated, and a strong centrifugal force can be generated, so that the soot in the flue gas is completely separated from the high-temperature gas, and the soot is left on the inner wall of the bent part 2, and then the soot is slowly slid into the collecting hopper 7 at the bottom of the bent part 2 according to the inclination of the U-shaped inner wall and falls into the collecting assembly in the inside of the collecting hopper 7 for collection, so that most of the soot can be effectively captured and collected without using mechanical equipment and manual injection intervention, the accumulation of the soot in the smoke exhaust pipe is reduced, the cleaning cycle of the pipe is prolonged, and the overall operation efficiency of the pipe is improved, and the gas after preliminary separation will continue to advance, and at this time the gas will pass through the filtering assembly arranged staggeredly one by one, and the filtering assembly can filter and separate the soot in the flue gas again so that the soot falls into the inside of the collecting hopper 7;

[0037] In addition, when the smoke dust accumulated inside the collection assembly reaches a certain amount, the baffle 9 can be pulled first to separate the magnetic block two 28 from the magnetic block one 27, so as to open the baffle 9, and then the controller 10 is used to drive the collection assembly to rotate to drive the smoke dust into the inside of the discharge box 8. At this time, according to the influence of gravity, the smoke dust will be discharged to the outside through the discharge box 8, so as to regularly clean the smoke dust in the collection assembly, greatly simplifying the maintenance process and reducing the labor cost.

[0038] With reference to Figure 1 , the connecting part between the smoke exhaust pipe one 1 and the bending part 2 is fixedly connected with a flange plate one 4, and the two flange plates one 4 are fixedly connected. The connecting part between the bending part 2 and the smoke exhaust pipe two 3 is fixedly connected with a flange plate two 5, and the two flange plates two 5 are fixedly connected.

Meanwhile, the sealing ring 6 can improve the sealing effect of the connecting part and reduce the leakage of smoke dust.

[0040] With reference to Figure 1 and Figure 2 , the collection assembly comprises a collection box 12 rotatably connected inside the collection bucket 7.

When the preset value is reached, the motor 14 can be started to rotate by the controller 10 to drive the collection box 12 to rotate inside the collection bucket 7. At this time, the opening of the collection cavity 13 will gradually change from upward to downward.

Meanwhile, when the collection box 12 drives the collection cavity 13 to rotate, the bottom of the collection box 12 will close the dust removal port at the bottom of the bending part 2. Therefore, the soot can still be cleaned when the incinerator and the boiler are working, which is more convenient in use.

[0042] With reference to Figure 1 , Figure 3 and Figure 4The filtering assembly comprises a plurality of sliding rails 16 fixedly connected to the inner wall of the bent portion 2 in a staggered manner, a through hole is formed through one side of the bent portion 2 in a staggered manner, a sealing plate 17 is slidably connected in the through hole, a connecting plate 18 is fixedly connected to one side of the sealing plate 17, a filtering plate 19 is clamped to the other side of the sealing plate 17, the filtering plate 19 is slidably connected in the sliding rail 16, a clamping piece is mounted on one side of the sealing plate 17, the clamping piece comprises a fixed block 20 fixedly connected to one side of the sealing plate 17, a groove is formed in the top of the fixed block 20, a spring 21 is fixedly connected inside the groove, a clamping block 22 is slidably connected inside the groove, one end of the spring 21 is fixedly connected to one end of the clamping block 22, an insertion slot 23 is formed in one side of the filtering plate 19, and a clamping groove 24 is formed in the top of the insertion slot 23.

[0043] In use, the gas after preliminary separation continues to advance, at this time the gas passes through the filtering plates 19 arranged in a staggered manner one by one, the filtering plates 19 can filter and separate the smoke dust in the flue gas again, so that the smoke dust falls into the inside of the collecting hopper 7, and when the filtering plates 19 need to be replaced, the connecting plate 18 is pulled to drive the filtering plates 19 to be pulled out from the inside of the bent portion 2 through the sealing plate 17, then one end of the clamping block 22 is manually extruded to be pushed into the inside of the fixed block 20, so that the clamping block 22 is separated from the clamping groove 24, at this time the sealing plate 17 is pulled to drive the spring 21 to be pulled out from the inside of the insertion slot 23, so as to quickly replace the filtering plates 19, and when the new filtering plates 19 are replaced, they can be reinserted into the inside of the bent portion 2, the position of the filtering plates 19 is guided and limited by the sliding rails 16, and the sealing property of the bent portion 2 is maintained by the sealing plate 17.

[0044] Referring to Figure 1 and Figure 3 , the smoke exhaust duct one 1 and the smoke exhaust duct two 3 are made of stainless steel, the bent portion 2 is made of carbon steel, and the surface of the bent portion 2 is provided with an anti-rust layer, which is a zinc plating film.

[0045] In use, the smoke exhaust duct one 1 and the smoke exhaust duct two 3 made of stainless steel have good high-temperature resistance and corrosion resistance, the surface of the bent portion 2 is sprayed with a zinc plating film, which can effectively improve the durability and corrosion resistance of the bent portion 2, effectively maintain the long-term stable operation of the equipment, and enhance the reliability and safety of the equipment.

[0046] The implementation principle of the connection structure of the incinerator and the boiler is as follows: in use, the flange plate 4 and the flange plate 5 are arranged, so that the bending part 2 can be stably connected between the smoke exhaust channel 1 and the smoke exhaust channel 3, and the sealing ring 6 is arranged, so that the sealing effect of the connection part is improved, and the leakage of smoke dust is reduced. When the high-temperature gas generated by the incinerator enters the inside of the smoke exhaust channel 1, the high-temperature gas first passes through the bending part 2 and then enters the boiler through the smoke exhaust channel 3. When the high-temperature gas carrying the soot passes through the bending part 2, the high-temperature gas collides with the inner wall of the bending part 2. Due to the inverted U-shaped design of the bending part 2, the propagation speed of the flue gas is accelerated, and a strong centrifugal force is generated, so that the soot in the flue gas is completely separated from the high-temperature gas, and the soot is deposited on the inner wall of the bending part 2. Then, the soot is slowly guided to slide to the collecting hopper 7 at the bottom of the bending part 2 according to the inclination of the U-shaped inner wall, and is collected in the collecting assembly inside the collecting hopper 7. In this way, most of the soot can be effectively captured and collected without using mechanical equipment and manual injection intervention, the accumulation of soot in the smoke exhaust pipe is reduced, the cleaning cycle of the pipe is prolonged, and the overall operation efficiency of the pipe is improved. The gas after preliminary separation continues to advance, and the gas passes through the filter plates 19 arranged in a staggered manner one by one. The filter plates 19 can filter and separate the soot in the flue gas again, so that the soot falls into the inside of the collecting hopper 7. When the filter plates 19 need to be replaced, the connecting plate 18 is pulled to drive the filter plates 19 to be extracted from the inside of the bending part 2 through the sealing plate 17. Then, one end of the clamping block 22 is manually extruded to push the clamping block 22 into the inside of the fixing block 20, so that the clamping block 22 is separated from the clamping groove 24. At this time, the sealing plate 17 is pulled to drive the spring 21 to be extracted from the insertion slot 23, so that the filter plates 19 can be quickly replaced. When the new filter plates 19 are replaced, the filter plates 19 can be reinserted into the inside of the bending part 2. The position of the filter plates 19 is guided and limited by the sliding rails 16, and the sealing property of the bending part 2 is maintained by the sealing plate 17.

[0047] In addition, the weight sensor 15 arranged in the collecting cavity 13 can monitor the collected weight of the soot in real time. When the collected weight reaches a preset value, the motor 14 can be started by the controller 10 to drive the collecting box 12 to rotate in the inside of the collecting hopper 7. At this time, the opening of the collecting cavity 13 is gradually changed from upward to downward. When the opening of the collecting cavity 13 reaches the bottom of the collecting hopper 7, the soot in the inside of the collecting cavity 13 is discharged to the outside through the discharge box 8 under the influence of gravity. In this way, the soot in the collecting assembly can be cleaned regularly, the maintenance process is greatly simplified, and the labor cost is reduced. When the collecting box 12 drives the collecting cavity 13 to rotate, the bottom of the collecting box 12 is not opened to close the dust removal port at the bottom of the bending part 2. Therefore, the soot can be cleaned when the incinerator and the boiler are working, and the use is more convenient.
