Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to an electric waste incinerator with a feeding pretreatment structure. Background Technology

[0002] Electric waste incinerators are a common type of equipment for treating municipal solid waste and special waste. They maintain high temperatures within the furnace through electric heating to achieve the harmless and volume-reduced treatment of waste. However, in actual operation, the complex composition of waste, especially its moisture content, has a crucial impact on incineration efficiency. When waste contains a large amount of moisture, the evaporation of moisture absorbs a significant amount of heat in the initial stages of incineration, making it difficult for the furnace temperature to quickly reach the ideal combustion temperature. This not only significantly increases energy consumption but may also produce harmful substances such as dioxins due to incomplete combustion and exacerbate equipment corrosion. Furthermore, untreated waste is usually large in volume and uneven in shape; direct incineration can easily lead to uneven material distribution and low pyrolysis and gasification efficiency, affecting the stability and processing efficiency of the entire incineration system.

Detailed Implementation

[0018] Please see Figure 1-13 The present invention provides a technical solution: an electric waste incinerator with a feeding pretreatment structure, comprising a furnace body 1 and a cover 2, the cover 2 being fixedly connected to the furnace body 1, a hopper 3 being installed on the cover 2, and a crushing mechanism for preliminary crushing of waste being provided inside the hopper 3; The cover 2 is equipped with a receiving frame 4 for receiving the garbage after preliminary crushing. The receiving frame 4 is divided into multiple chambers arranged in a circular array. Each chamber is equipped with a crushing mechanism 2 for secondary crushing of the garbage. Each receiving frame 4 contains a dehydration mechanism, which is used to remove the moisture contained in the pre-crushed waste in each chamber. The dehydration mechanism includes a filter plate 5 installed inside the receiving frame 4 chamber, with the filter plate 5 located at the inner and outer edges of the chamber. The dehydration mechanism also includes a rotating component and an arranging component. The rotating component is used to drive the receiving frame 4 to rotate relative to the cover 2. The arranging component is used to evenly spread the waste in the chamber onto the surface of the filter plate 5. A conveying mechanism is installed at the bottom of the receiving frame 4. The conveying mechanism is used to transport the secondary crushed waste into the furnace body 1. During operation, before incinerating the waste, the furnace body 1 is preheated, and then the waste to be incinerated is put into the hopper 3. The waste is then initially crushed by activating the crushing mechanism in the hopper 3. The initially crushed waste falls into the receiving frame 4 and is evenly distributed in each chamber of the receiving frame 4; by starting the rotating component, the receiving frame 4 can be driven to rotate. When the receiving frame 4 rotates, the centrifugal force and the filter plate 5 work together to throw out the water contained in the waste in the chamber; by dispersing the waste into multiple chambers, the waste can be processed in batches, which can effectively improve the effect of separating water from the waste, and also facilitates the secondary crushing of the waste by the subsequent crushing mechanism 2, which can effectively improve the crushing effect of the waste. When the waste enters the chamber, the arrangement mechanism can evenly spread the waste on the filter plate 5, increasing the surface area for waste dehydration and further improving the effect of separating water from the waste. After the waste in the chamber is dehydrated, it can be pulverized a second time by starting the pulverizing mechanism. After the second pulverization, the incompletely pulverized parts of the waste can be completely pulverized, so as to improve the incineration effect of the furnace body 1 on the waste. The waste that has undergone dehydration and secondary crushing is transported by a conveying mechanism into furnace 1 for incineration.

[0019] See Figure 3-4 As a further embodiment of the present invention, the crushing mechanism includes a drive component 6 fixed on the hopper 3; two crushing cylinders 7 are rotatably connected inside the hopper 3, and the drive component 6 has two output shafts and is fixedly connected to the two crushing cylinders 7 respectively; a material pipe 8 is fixedly connected to the bottom of the hopper 3, the material pipe 8 is fixedly connected to the cover 2 and the bottom of the material pipe 8 is rotatably connected to the receiving frame 4; a water-draining component is provided on the material pipe 8, which is used to initially drain the water from the garbage crushed by the two crushing cylinders; The drain assembly includes a valve body 9 fixed at the root of the material pipe 8, and a valve core 10 slidably connected to the cover 2 inside the valve body 9; the material pipe 8 is inclined and has multiple drain holes on the lower part of the material pipe 8; a water channel 11 is provided directly below the drain holes and is fixedly connected to the cover 2. During operation, when garbage is put into hopper 3, the drive unit 6 is activated to drive the two crushing cylinders 7 to start rotating. The two crushing cylinders 7 crush large pieces of garbage into smaller pieces, which then continuously fall into the feed pipe 8 and slide down along the feed pipe 8. When the crushed garbage contains moisture, most of the moisture inside the garbage is squeezed out during crushing. The squeezed-out moisture flows along the feed pipe 8 and flows out through the drain hole on the feed pipe 8. The water that flows out eventually falls into the water inlet trough 11, where the staff can collect the water flowing out of the water inlet trough 11 for centralized treatment. When the two crushing cylinders 7 are crushing the waste, the crushed waste can be temporarily kept in the feed pipe 8 by closing the valve body 9. The waste staying in the feed pipe 8 can promote the secondary crushing of waste in batches by the crushing mechanism and the incineration of waste in batches by the furnace body 1, which can further improve the waste incineration effect. At the same time, it can also ensure that the waste in the feed pipe 8 has sufficient time to drain.

[0020] See Figure 6-7 , Figure 10As a further embodiment of the present invention, the second crushing mechanism includes two crushing cylinders 12 arranged in an inclined state in the chamber, and the crushing cylinders 12 are rotatably connected to the receiving frame 4; a driving component 13 is installed on the receiving frame 4 at the outer side of each chamber, the driving component 13 has two output shafts and is fixedly connected to the two crushing cylinders 12 in the chamber respectively; a connecting block 14 is fixedly connected to the middle position inside the receiving frame 4, and the connecting block 14 is rotatably connected to multiple crushing cylinders 12 at the same time; During operation, when the initially crushed waste enters the receiving frame 4 along the material pipe 8, the waste will be evenly dispersed and fall into each chamber. By activating the drive component 13 on the outside of the chamber, the two crushing cylinders 12 inside the chamber can be rotated, and the waste falling into the chamber can be crushed a second time through the two crushing cylinders 12.

[0021] See Figure 6-7 , Figure 9-10 , Figure 13 As a further embodiment of the present invention, the rotating assembly includes a motor 15 fixed to the outside of the cover 2, and a pulley 16 fixedly connected to the bottom end of the output shaft of the motor 15; the receiving frame 4 is rotatably connected to the cover 2 and a pulley 18 fixedly connected to the bottom of the receiving frame 4, and a belt 17 is provided on the pulley 18, which is simultaneously connected to both the pulley 16 and the pulley 18; a water collection groove 35 is provided on the inner wall of the cover 2, and a drain outlet 36 is provided on the outer surface of the cover 2 at the bottom of the water collection groove 35; The arrangement assembly includes a telescopic frame 19 located in each chamber and rotatably connected to the inner wall of the receiving frame 4. A groove 20 is provided on the inner wall of the receiving frame 4 near the filter plate 5. The telescopic part of the telescopic frame 19 is slidably connected to the groove 20. The groove 20 is vertical and the upper part of the groove 20 is curved inward. A telescopic baffle 21 is provided on the upper side of the telescopic frame 19. The telescopic baffle 21 is fixedly connected to the receiving frame 4 and the bottom end of the telescopic baffle 21 is attached to the telescopic frame 19. The width of the telescopic baffle 21 is equal to the width of the telescopic frame 19 and the telescopic baffle 21 has an elastic telescopic function. A drive assembly is provided on the cover 2. The drive assembly is used to drive the valve body 9 to close, the telescopic frame 19 to rotate, and the filter plate 5 to rotate in sequence. During operation, before the secondary crushing of waste in the second crushing cylinder 12, the motor 15 drives the pulley 16 to rotate. The pulley 16 drives the pulley 2 18 to rotate via the belt 17. The pulley 2 18 then drives the receiving frame 4 to rotate. When the receiving frame 4 rotates, the waste is thrown into the telescopic frame 19 by centrifugal force and then thrown into the chamber along the telescopic frame 19. The telescopic frame 19 has a limiting effect, which can restrict the position of the waste entering the chamber. After the waste is thrown into the chamber, it adheres to the surface of the filter plate 5 under the action of centrifugal force. At this time, the drive component is activated. The drive component first drives the valve body 9 to close and then drives the telescopic frame 19 to rotate upward. The opening of the telescopic frame 19 moves upward along the filter plate 5 under the action of the slide chute 20, and the waste thrown into the chamber will be spread flat on the filter plate 5. When the telescopic end of the telescopic frame 19 moves to the uppermost position in the slide chute 20, the telescopic frame 19 stops rotating. Under the action of centrifugal force, the waste spread flat on the filter plate 5 can quickly throw out the water contained in the waste. The thrown-out water adheres to the inner wall of the water collection tank 35 and flows downward, and finally is discharged and collected along the drain outlet 36. When the telescopic frame 19 stops rotating, the drive assembly starts to drive the filter plate 5 to rotate towards the crushing cylinder 12. The filter plate 5 brings the garbage attached to its surface closer to the crushing cylinder 12. When the filter plate 5 rotates to the position where it is in contact with the crushing cylinder 12, the crushing cylinder 12 can then pull the garbage on the filter plate 5 between the two crushing cylinders 12 and complete the secondary crushing. While the crushing cylinder 12 is crushing the garbage for the second time, because the garbage is spread flat on the filter plate 5, the contact area between the garbage and the crushing cylinder 12 is large, and the crushing cylinder 12 can complete the secondary crushing of this batch of garbage in a short time.

[0022] See Figure 3-9 , Figure 11-12 As a further embodiment of the present invention, the driving assembly includes a base 22 vertically slidably connected to the bottom of the cover 2, and two springs 23 connected between the base 22 and the cover 2; a sliding frame 24 is symmetrically slidably connected to the front and rear positions of the outer side of the cover 2, and a cylinder 25 is fixedly connected to the sliding frame 24, with the bottom telescopic end of the cylinder 25 fixedly connected to the base 22; a connecting rod 26 is rotatably connected to the sliding frame 24, and the upper ends of the connecting rods 26 on both the front and rear sides are rotatably connected to the valve core 10; a rotating ring 27 is rotatably connected to the base 22 and vertically slidably connected to the receiving frame 4, and a driving unit 1 and a driving unit 2 are mounted on the rotating ring 27, which are respectively used to drive the telescopic frame 19 and the filter plate 5 to rotate; The drive unit includes multiple push rods 28 slidably connected to the rotating ring 27. The upper part of the push rod 28 is slidably connected to the receiving frame 4, and a spring 29 is fixedly connected to the push rod 28. The bottom end of the spring 29 is fixedly connected to the rotating ring 27. Two connecting rods 30 are rotatably connected to the upper end of the push rod 28. A connecting rod 31 is rotatably connected to the upper end of the connecting rods 30. The upper part of the connecting rod 31 is fixedly connected to the rotating shaft of the telescopic frame 19. The second drive unit includes multiple racks 32 fixed on the rotating ring 27. A gear 33 is provided on the upper side of the rack 32. The gear 33 is fixedly connected to the rotating shaft of the filter plate 5. A torsion spring is installed at the connection between the gear 33 and the receiving frame 4 to keep the filter plate 5 stationary. During operation, when a batch of drained waste falls into the receiving frame 4 from the material pipe 8, the cylinders 25 on both sides begin to retract. As the cylinders 25 retract, under the action of spring 23, they drive the sliding frame 24 to slide downwards. The sliding frame 24, through connecting rod 26, pulls the valve core 10 into the valve body 9. When the valve core 10 completely closes the valve body 9, the sliding frame 24 can no longer slide downwards. As the cylinders 25 continue to retract, they begin to drive the base 22 to compress the spring 23 and move upwards. The base 22 drives the rotating ring 27 to move upwards, and the rotating ring 27 drives multiple racks 32 and multiple... Spring 29 drives multiple push rods 28 to move upward. When the push rods 28 move upward, they push the connecting rod 31 to rotate upward through the connecting rod 30. The connecting rod 31 then drives the telescopic frame 19 to rotate upward. When the telescopic frame 19 rotates to the uppermost side, it can no longer rotate. The rotating ring 27 then begins to compress spring 29, which drives the rack 32 to continue moving upward. When the rotating ring 27 compresses spring 29, the rack 32 just meshes with the gear 33 located above it. As the rack 32 moves upward, it drives the filter plate 5 to start rotating downward through the gear 33. When the filter plate 5 rotates to the angle that it is in contact with the crushing cylinder 12, the cylinder 25 can be stopped. After the secondary crushing of waste is completed in the crushing cylinder 12, the starting cylinder 25 begins to reset. The cylinder 25 drives the rotating ring 27 to move downward, and the rotating ring 27 drives the rack 32 to move downward. The filter plate 5 will be the first to complete the reset. After the rack 32 disengages from the gear 33, the spring 29 returns to its normal length. When the rotating ring 27 continues to move downward, it drives the top rod 28 to move downward through the spring 29. The top rod 28 then gradually drives the telescopic frame 19 to reset. After the telescopic frame 19 resets, the rotating ring 27 and the base 22 move to the bottom position. At this time, the cylinder 25 begins to push the sliding frame 24 upward. When the sliding frame 24 moves upward, it drives the valve core 10 to open the valve body 9 through the connecting rod 26. At this time, a new round of waste will automatically fall into the receiving frame 4.

[0023] See Figure 1-2 As a further embodiment of the present invention, the conveying mechanism includes an auger feeder 34 fixed on the furnace body 1; the bottom discharge port of the receiving frame 4 is rotatably connected to the feed port of the auger feeder 34. During operation, the waste that has undergone secondary crushing falls into the screw conveyor through the discharge port at the bottom of the receiving frame 4. Then, the screw conveyor is started to transport the waste that has undergone secondary crushing into the furnace body 1 for incineration.
