Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices for incinerators, and in particular to a feeding device for an incinerator. Background Technology

[0002] In the incineration process of municipal solid waste, moisture content is one of the key factors affecting incineration efficiency and treatment effect. Municipal solid waste has a complex composition, containing a large amount of food waste, waste paper, fabrics, and other materials that easily absorb moisture, resulting in a generally high overall moisture content. When this high-moisture municipal solid waste enters the incinerator, the moisture rapidly absorbs heat and vaporizes in the high-temperature furnace, consuming a large amount of heat generated by combustion. This makes it difficult to maintain the furnace temperature within the ideal combustion range, not only reducing combustion efficiency but also potentially causing incomplete combustion of organic matter due to insufficient temperature. Furthermore, when moisture mixes with incompletely burned particulate matter, it easily forms slag or corrosion on the furnace inner wall and heated surfaces, affecting the heat transfer efficiency and service life of the incinerator and increasing equipment maintenance costs. Therefore, we propose a feeding device for the incinerator. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for an incinerator.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for an incinerator, comprising an incinerator, wherein a dehydration inlet is provided at the top of the incinerator, a dehydration box is fixedly provided at the top of the incinerator directly above the dehydration inlet, a gantry frame is fixedly installed at the top of the dehydration box, a drive cylinder is fixedly installed at the top of the gantry frame, a dehydration plate is slidably installed inside the dehydration box, fixing blocks are fixedly installed on both sides of the dehydration box, a feeding rod is fixedly connected to the bottom of each of the two fixing blocks, and a feeding component is provided on the fixing block.

A filter plate is slidably installed between the inner walls of the two sides of the dehydration tank, and the outer walls of the filter plate are tightly fitted to the inner walls of the dehydration tank. The surface of the filter plate has a number of filter holes arranged in a matrix. The top of the filter plate is inclined from the middle to both sides. The bottom of the dehydration plate is adapted to the shape of the top of the filter plate. A water collection tank is fixedly connected to the bottom of the filter plate. A sealing pipe is slidably installed on both sides of the water collection tank.

[0008] Preferably, a synchronous shaft is fixedly connected to each of the two notches on both sides of the filter plate, and the two synchronous shafts extend out of the two notches respectively.

[0009] Preferably, the top ends of the two feeding rods extend beyond the tops of the two fixing blocks and are fitted with nail covers, and a return spring is fitted between the outer walls of the two feeding rods and the fixing blocks and nail covers.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model achieves initial dehydration through the filter holes of the filter plate, and then uses a drive cylinder to push the dehydration plate to squeeze the waste. This dual action effectively removes free water from municipal solid waste. After treatment, the moisture content of the waste is significantly reduced, which reduces the heat consumed by water vaporization when it enters the incinerator. This helps maintain the furnace temperature within the ideal combustion range, improves the completeness of organic matter combustion, and increases incineration efficiency.

[0013] In use, this invention effectively removes moisture from waste, preventing it from mixing with incompletely burned particles. This reduces the likelihood of slagging or corrosion on the furnace walls and heating surfaces. This minimizes the impact on the incinerator's heat transfer efficiency, reduces maintenance frequency and costs, extends the incinerator's lifespan, and solves the problem of equipment wear and tear caused by moisture.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a feeding device for an incinerator is disclosed, including an incinerator 1. A dehydration inlet 2 is provided on the top of the incinerator 1. A dehydration box 3 is fixedly provided on the top of the incinerator 1 directly above the dehydration inlet 2. A gantry frame 5 is fixedly installed on the top of the dehydration box 3. A drive cylinder 6 is fixedly installed on the top of the gantry frame 5. A dehydration plate 7 is slidably installed inside the dehydration box 3. Fixing blocks 14 are fixedly installed on both sides of the dehydration box 3. A feeding rod 15 is fixedly connected to the bottom of each of the two fixing blocks 14. A feeding component is provided on the fixing blocks 14.

[0023] Mounting plates 4 are fixedly installed on both sides of the dehydration tank 3, and the dehydration tank 3 is fixedly connected to the top of the incinerator 1 by the two mounting plates 4.

[0024] The piston rod of the drive cylinder 6 extends out of the gantry 5 and is fixed to the top of the dewatering plate 7 at the corresponding middle position. The drive cylinder 6 provides power to push the dewatering plate 7 down. The bottom of the dewatering plate 7 is adapted to the shape of the top of the filter plate 8, so that it can fit tightly against the garbage and apply pressure to further squeeze out the water trapped in the garbage. Together with the filter holes 9, it achieves double dewatering, which greatly reduces the moisture content of the garbage. Compared with simple filtration, squeeze dewatering can remove more bound water, reduce heat loss during incineration, and help the furnace maintain an ideal temperature.

[0025] On both sides of the dewatering tank 3, directly below the two fixed blocks 14, there are notches 10 extending to the bottom of the dewatering tank 3. Filter plates 8 are slidably installed between the inner walls of the two sides of the dewatering tank 3, and the outer walls of the filter plates 8 are tightly fitted to the inner walls of the dewatering tank 3. The surface of the filter plates 8 has several filter holes 9 arranged in a matrix. The top of the filter plates 8 is inclined from the middle to both sides. The bottom of the dewatering plate 7 is adapted to the shape of the top of the filter plates 8. A water collection tank 11 is fixedly connected to the bottom of the filter plates 8. Sealing pipes 12 are slidably installed on both sides of the water collection tank 11. The structure of the top of the filter plates 8 being inclined from the middle to both sides can both receive garbage and facilitate the sliding of garbage after dewatering. The filter holes 9 on the surface can quickly filter free water in the garbage to achieve preliminary dewatering. Water flows into the water collection tank 11 efficiently through the filter holes 9, reducing the water entering the incinerator 1. The water collection tank 11 can collect the water generated by filtration and squeezing, avoiding water from flowing randomly and causing pollution. The sealing pipes 12 can control water discharge and facilitate centralized treatment.

[0026] Synchronous shafts 13 are fixedly connected to the two notches 10 on both sides of the filter plate 8, and the two synchronous shafts 13 extend out of the two notches 10 respectively.

[0027] The top ends of the two feeding rods 15 extend out of the top of the two fixing blocks 14 and are fitted with nail covers 16. The outer walls of the two feeding rods 15 are fitted with return springs 17 between the fixing blocks 14 and the nail covers 16.

[0028] The feeding assembly includes a rotating shaft 18, a rotating disk 19, an arc plate 20, and an arc-shaped groove 21. The rotating shaft 18 is fixedly connected to the opposite side of the two fixed blocks 14. The rotating disk 19 is rotatably sleeved at the end of the two rotating shafts 18. The arc-shaped plate 20 is fixedly connected to the inner side of the two rotating disks 19 near the edge. The arc-shaped groove 21 that matches the arc plate 20 is opened on the outer side of the two feeding rods 15 corresponding to the bottom of the fixed blocks 14. The two arc plates 20 are slidably engaged in the two arc-shaped grooves 21 respectively. The rotating disk 19 on the rotating shaft 18 can drive the arc plate 20 to rotate. When the arc plate 20 slides out of the arc-shaped groove 21, the feeding rod 15 is released from the limit, so that the filter plate 8 can be smoothly moved down to unload the material. Reverse rotation can re-limit and fix it, realizing convenient feeding of the dewatered waste without manual handling, reducing labor intensity, and ensuring that the waste can fall accurately into the dewatering inlet 2.

[0029] Working principle: When in use, the piston rod on the drive cylinder 6 first retracts to raise the dehydration plate 7 in the dehydration tank 3. The garbage to be incinerated is poured into the dehydration tank 3 through the gap between the dehydration plate 7 and the dehydration tank 3. The garbage falls onto the filter plate 8 and undergoes preliminary water filtration through several sets of filter holes 9 on the surface of the filter plate 8. The water flows into the water collection tank 11 for temporary storage through the filter holes 9. Next, the piston rod on the drive cylinder 6 is pushed downwards, causing the dewatering plate 7 to slide downwards within the dewatering tank 3. Its bottom surface contacts the inclined surface of the top of the filter plate 8. As the piston rod applies pressure, it compresses the waste on the surface of the filter plate 8, further squeezing out the free water trapped within. The squeezed-out water also flows through the filter holes 9 into the water collection tank 11. At this time, the sealing pipe 12 is closed, ensuring effective water collection within the water collection tank 11. After the waste water is squeezed out, the rotating disk 19 is rotated to ninety degrees on the two rotating shafts 18, causing the arc plate 20 inside the rotating disk 19 to slide out of the arc-shaped slot 21. The feeding rod 15 releases the limiting position of the arc plate 20. The dewatering plate 7 continues to apply downward pressure, pushing the filter plate 8 downwards within the dewatering tank 3. The synchronous shafts 13 on both sides of the filter plate 8 move synchronously downwards along the notch 10, driving the feeding rod 15 to the fixed block 1. As the filter plate 8 slides down, the nail cover 16 moves down and presses the return spring 17, causing the return spring 17 to contract and deform. After the filter plate 8 slides out of the bottom of the dewatering tank 3, due to its top structure which is inclined from the middle to both sides, the dewatered waste on the surface slides down into the dewatering feed inlet 2 of the incinerator 1 under the action of gravity and enters the incinerator for incineration. After the waste is fed, the piston rod on the control drive cylinder 6 retracts, the dewatering plate 7 returns to its original position, and at the same time, the rebound force of the return spring 17 pushes the nail cover 16 to move up, driving the feed rod 15 and the filter plate 8 back to the dewatering tank 3. The rotating disk 19 is rotated in the opposite direction, so that the arc plate 20 is re-engaged into the arc-shaped slot 21, limiting the feed rod 15 to fix the position of the filter plate 8. Finally, the sealing pipe 12 is opened to discharge the water collected in the water collection tank 11 through the sealing pipe, completing one dewatering-feeding cycle, so as to process the next batch of waste.
