Description

Technical Field

[0001] This invention belongs to the field of waste incineration technology, specifically a waste incineration fly ash treatment device. Background Technology

[0002] Waste incineration for power generation is currently the mainstream method for reducing and harmlessly treating solid waste. A large amount of fly ash is generated during the incineration process. The fly ash is rich in heavy metals, dioxins and other toxic and harmful substances, and is classified as hazardous waste. If it is directly dumped or landfilled, the harmful substances can easily seep into the soil and groundwater with rainwater, causing water and soil pollution. At the same time, there is a risk of atmospheric diffusion pollution, which harms the ecological environment and human health.

[0003] To address the pollution problem of harmful substances in fly ash, dry separation methods suitable for bulk materials have been gradually applied in fly ash treatment. This method mainly separates solid fly ash from solid mixtures through fine sieving, coarse sieving, or airflow, achieving graded purification of fly ash. Fine and coarse sieving are used together to grade fly ash particles based on their size differences. Airflow separation utilizes the differences in gravity and air resistance between fly ash particles of different sizes to achieve efficient separation. Dry separation is widely used in fly ash treatment because it is suitable for the processing characteristics of bulk fly ash and is easy to operate.

[0004] A Chinese patent with publication number CN115780229B discloses a waste incineration fly ash treatment device, including a treatment box and a negative pressure machine. The treatment box is equipped with a stepper motor, a fly ash inlet, a fly ash outlet, and an annular filter screen. A support rod is fixed between the stepper motor and the annular filter screen. The incoming airflow is filtered by rotating the annular filter screen.

[0005] Existing fly ash treatment devices filter fly ash from the airflow through filters. However, a large number of solid particles of different sizes are present in the airflow during use. If only filters with small pores are used for filtration, larger particles will quickly clog the pores. At this time, the clogged areas cannot be filtered, which affects the filtration efficiency.

[0006] Therefore, the present invention provides a waste incineration fly ash treatment device. Summary of the Invention

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the embodiment of the present invention, a waste incineration fly ash treatment device includes a shell 1. An exhaust pipe 11 is fixed at the top of the interior of the shell 1, and the top of the exhaust pipe 11 extends out from the top of the shell 1. Multiple air inlets 12 are fixed at equal intervals on the exterior of the shell 1. A support frame 13 is fixed at the bottom of the shell 1. A cylinder 131 is installed at the top of the interior of the support frame 13. A lifting plate 15 is fixed at the end of the output shaft of the cylinder 131. A filter element 14 is rotatably connected inside the shell 1. The bottom end of the exhaust pipe 11 extends into the interior of the filter element 14. Multiple blades 143 are distributed at equal intervals on the outer side of the filter element 14. In use, the end of the inlet pipe 12 is connected to the waste incineration exhaust pipe, and the outlet pipe 11 is connected to the pipeline of the subsequent treatment equipment. An extraction device is installed at the connection point of the outlet pipe 11. The waste incineration exhaust pipe discharges the generated exhaust gas into the interior of the inlet pipe 12. Simultaneously, the extraction device at one end of the outlet pipe 11 assists in extraction, which can accelerate the airflow inside the outer casing 1. Figure 1It can be seen that the connection between the air intake pipe 12 and the outer shell 1 is set at an angle. When air is discharged from inside the air intake pipe 12, it will blow towards the surface of the filter element 14 at a certain angle. At this time, the blades 143 on the outside of the filter element 14 will be pushed by the airflow. The blades 143 will drive the filter element 14 to roll inside the outer shell 1, so that the filter element 14 can filter the airflow input from the air intake pipe 12 while rotating. The airflow ejected from the air intake pipe 12 contains a large amount of fly ash. When the fly ash comes into contact with the surface of the filter element 14, it is filtered out. Some of the fly ash falls downwards, and the other part of the fly ash adheres to the filter element 14. The surface of the filter element 14 is rotated by the blades 143, which allows the fly ash to adhere evenly to the outside of the filter element 14, thus preventing the fly ash from accumulating and causing the filter element 14 to fail to filter properly. During the process, the cylinder 131 pushes the lifting plate 15 to seal the bottom of the outer shell 1, thereby ensuring the sealing of the filtration process. At the same time, after a certain filtration time, the cylinder 131 is activated to lower the lifting plate 15, at which time the fly ash filtered inside the outer shell 1 can be cleaned, which can facilitate the removal of fly ash and reduce the clogging of the filter element 14.

[0025] like Figures 1 to 4 As shown, three sets of filter covers 141 of different diameters are fixed to the bottom of the filter element 14. The three sets of filter covers 141 are arranged in descending order of diameter at the bottom of the filter element 14. Filter holes are provided on the outer side of each of the three sets of filter covers 141. The outermost filter cover 141 has the largest filter holes, and the innermost filter cover 141 has the smallest filter holes. A conical guide tube 142 is fixed to the bottom of the filter cover 141. The size of the three sets of conical guide tubes 142 matches the size of the three sets of filter covers 141. The bottoms of the three sets of conical guide tubes 142 are flush, and the top of the lifting plate 15 can be close to the bottom of the conical guide tube 142. During use, the airflow first passes through the outermost filter cover 141, which has the largest filter holes and can filter out the largest particles in the fly ash. Then, the middle filter cover 141 and the innermost filter cover 141 filter out particles of different diameters respectively, thus achieving simultaneous screening of different levels. The fly ash at the bottom of the screening is guided downward by the conical guide pipe 142 and falls to the top of the lifting plate 15, thereby achieving multi-stage screening.

[0026] like Figures 1 to 4 As shown, a positioning ring 144 is fixed at the top of the outermost filter cover 141, and multiple rollers 145 are fixed in a ring shape at the bottom of the inner shell 1. Rollers are rotatably connected to the top and bottom of the rollers 145, and the positioning ring 144 is placed between two rollers. When the filter element 14 rotates, the filter element 14 drives the positioning ring 144 to rotate. At this time, the positioning ring 144 rolls inside multiple roller frames 145. The rollers inside the roller frames 145 support the positioning ring 144, reducing the resistance to the rotation of the filter element 14, thus making it easier for the blades 143 to drive the filter element 14 to rotate.

[0027] like Figures 1 to 5 As shown, the top of the lifting plate 15 is rotatably connected to three sets of rotating rings 153 with different diameters, and the diameters of the three sets of rotating rings 153 match the diameter of the bottom end of the tapered guide tube 142. When the lifting plate 15 is connected to the bottom end of the conical guide tube 142, in order not to affect the rotation of the filter element 14, a rotating ring 153 is set at the top of the lifting plate 15. When the cylinder 131 drives the lifting plate 15 to the highest position, the three rotating rings 153 are respectively attached to the bottom ends of the three conical guide tubes 142. When the filter element 14 rotates, the conical guide tube 142 drives the rotating rings 153 to rotate, which can prevent the lifting plate 15 from being attached to the conical guide tube 142 and causing the filter element 14 to be unable to rotate.

[0028] like Figures 1 to 5 As shown, multiple rotating plates 152 are rotatably connected at equal intervals on the outer side of the lifting plate 15. A baffle cloth 151 is fixed to the top of the lifting plate 15. The rotating plate 152 is fixedly connected to the baffle cloth 151 on the side near the center of the lifting plate 15. The baffle cloth 151 has extensibility. When the lifting plate 15 collects fly ash, in order to enable the lifting plate 15 to collect more fly ash, a baffle cloth 151 is set to block the periphery of the lifting plate 15, and at the same time, the rotating plate 152 supports the baffle cloth 151. The fly ash is stored inside the baffle cloth 151, so that the top of the lifting plate 15 can collect more fly ash.

[0029] like Figures 1 to 5 As shown, a top flared mouth 132 is fixed to the bottom end of the outer casing 1, and a bottom flared mouth 133 is fixed to the bottom end of the top flared mouth 132. The maximum outward rotation angle of the rotating plate 152 matches the slope angle of the top flared mouth 132, and the slope angles of the top flared mouth 132 and the bottom flared mouth 133 match. Initially, the lifting plate 15 is raised to its highest position. Due to the gravity of the rotating plate 152, it rotates towards the inclined surface of the top flared opening 132. At this time, the baffle cloth 151 is driven to expand outward, forming a flared shape with the same angle as the top flared opening 132. The baffle cloth 151 can then collect more fly ash. When the lifting plate 15 descends, it drives the rotating plate 152 to descend as well. The limit at the bottom of the top flared opening 132 causes the rotating plate 152 to pull the baffle cloth 151 in the direction of the lifting plate 15. When the lifting plate 15 moves below the bottom flared opening 133, the rotating plate 152 loses its position. When the limiting force is rotated outwards to open, the lifting plate 15 is placed below the outer shell 1, which makes it convenient for workers to use dust suction equipment to collect the fly ash at the top of the lifting plate 15. After collection, the lifting plate 15 needs to be reset. At this time, the lifting plate 15 drives the rotating plate 152 to rise. During this process, the rotating plate 152 is in a state of extending outwards. Under the guidance of the inclined surface of the bottom flared mouth 133, the rotating plate 152 can gradually retract towards the middle of the lifting plate 15. When the lifting plate 15 rises to the highest point, the rotating plate 152 opens outwards due to gravity and returns to the initial state, which can facilitate the entry of dust into the baffle cloth 151.

[0030] like Figures 1 to 7 As shown, a telescopic column 16 is fixed at the middle of the top of the lifting plate 15. Multiple sets of striking blocks 161 are connected to the outside of the telescopic column 16 in a spiral upward rotation. A spring piece 1612 is provided on one side of the striking block 161. The spring piece 1612 is fixedly connected to the telescopic column 16. A triggering component is provided inside the telescopic column 16. During the descent of the lifting plate 15, fly ash will remain on the surface of the filter cover 141, requiring cleaning. As the lifting plate 15 moves downward, it drives the telescopic column 16 to move downward simultaneously. At this time, the triggering component inside the telescopic column 16 will trigger the striking blocks 161 one by one from top to bottom. The spring 1612 pushes the striking blocks 161 to rotate, allowing the striking blocks 161 to strike the innermost conical guide tube 142. The impact is transmitted through the conical guide tube 142 to the entire filter element 14 and filter cover 141, causing the filter cover 141 to vibrate and shake off the fly ash on its surface. After being struck by multiple striking blocks 161, the fly ash on the surface of the filter cover 141 can be quickly shaken off, making it easier for workers to clean.

[0031] like Figures 1 to 8As shown, the triggering component includes slots 1611 on both sides of the striking block 161. Movable plates 1613 are provided on both sides of the striking block 161, and the movable plates 1613 are slidably connected to the interior of the telescopic column 16. A wedge-shaped locking block 1615 is fixed to one end of the movable plate 1613, and the wedge-shaped locking block 1615 can engage with the slots 1611. A wedge-shaped block 1614 is fixed to the other end of the movable plate 1613. A guide post 1617 is fixed to the side of the movable plate 1613 away from the striking block 161, and the guide post 1617 is slidably connected to... Inside the telescopic column 16, a first spring 1616 is sleeved on the outside of the guide column 1617. A sliding cavity 164 is opened in the middle of the telescopic column 16. A lifting block 165 is slidably connected inside the sliding cavity 164. Multiple sets of rotating blocks 1651 are rotatably connected at equal intervals on the outside of the lifting block 165. A steel rope 163 is fixed to the top of the lifting block 165. The top of the steel rope 163 extends from the top of the telescopic column 16. A connecting frame 162 is fixed to the top of the steel rope 163. The connecting frame 162 is fixedly connected to the bottom end of the air outlet pipe 11. When the lifting plate 15 lowers the telescopic column 16, the air outlet pipe 11 limits the connecting frame 162, allowing the connecting frame 162 to hold the steel cable 163. At this time, the steel cable 163 pulls the lifting block 165 upward from the bottom of the sliding cavity 164. The lifting block 165 drives the rotating block 1651 upward. In the initial state, the wedge-shaped locking block 1615 is locked inside the slot 1611. When the top of the rotating block 1651 passes the wedge-shaped block 1614, the inclined surface of the wedge-shaped block 1614 pushes the wedge-shaped block 1614 to both sides, simultaneously driving the moving plate 1613 to separate the wedge-shaped locking block 1615 from the slot 1611. At this time, the striking block 161 can be released from its limit and, through the spring piece 1612, it strikes the conical guide tube 142. After the striking block 161 strikes, the inclined surface inside the conical guide tube 142 will push the striking block 161 back into the telescopic column. Inside the retractable column 16, the wedge-shaped locking block 1615 can re-engage into the slot 1611, thereby automatically resetting the striking block 161. Due to the spiral upward arrangement, there is a distance space between two adjacent striking blocks 161, which can be used for the resetting of the striking block 161. This ensures that the resetting of the striking block 161 does not affect the next striking block 161 striking the conical guide tube 142. After the striking block 161 is reset, it does not affect the lifting plate 15 driving the telescopic column 16 to rise and reset. When the telescopic column 16 rises and resets, the lifting block 165 will fall downward due to gravity. When the bottom end of the rotating block 1651 passes the wedge-shaped block 1614, it is pushed by the wedge-shaped block 1614 to rotate in the direction of the lifting block 165. After passing the wedge-shaped block 1614, the rotating block 1651 automatically rotates and resets due to gravity, thus facilitating the downward movement of the rotating block 1651.

[0032] like Figures 1 to 8 As shown, the outer side of the lifting block 165 is provided with an inclined groove 1652, and the rotating block 1651 can rotate into the inclined groove 1652. The inclined groove 1652 allows the rotating block 1651 to rotate at an angle of less than 90°, preventing the rotating block 1651 from being pushed to rotate 90° and failing to return to its normal position.

[0033] like Figures 1 to 8 As shown, a second spring 166 is sleeved on the outside of the steel rope 163. The bottom end of the second spring 166 is fixedly connected to the top end of the lifting block 165, and the top end of the second spring 166 is fixedly connected to the top end of the inner wall of the sliding cavity 164. When the lifting block 165 is reset, the second spring 166 can push the lifting block 165, thereby assisting the lifting block 165 to reset downwards and avoiding jamming with the inner wall of the sliding cavity 164.
