Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a mobile feeding mechanism for a waste pyrolysis gasification furnace. Background Technology

[0002] In today's society, with the acceleration of urbanization and the improvement of people's living standards, the amount of waste generated is increasing day by day. Waste pyrolysis gasification technology, as an advanced waste treatment method, has received widespread attention due to its significant advantages such as volume reduction, harmlessness, and resource recovery. As the core equipment of this technology, the performance of the waste pyrolysis gasification furnace directly affects the effectiveness and efficiency of waste treatment.

[0003] The feeding mechanism plays a crucial role in the operation of a waste pyrolysis gasification furnace. Currently, the common feeding method for waste pyrolysis gasification furnaces is to feed waste into the gasification furnace through a grabbing device via a hopper, which is usually installed at the top of the gasification furnace. However, this existing feeding method has many problems.

[0004] First, the waste fed into the hopper is diverse and complex. Due to its wide range of origins, the waste varies in size and shape, and some pieces may be tangled together. This characteristic makes blockages very likely during the feeding process. When waste clogs the hopper, it not only affects the normal feeding process, causing obstructions or even interruptions, but also increases equipment maintenance costs and downtime, reducing the overall efficiency of the waste treatment system.

[0005] Secondly, most existing waste disposal equipment uses gravity-based free fall or unidirectional mechanical pushing, which makes it difficult to control the waste's landing point and accumulation pattern. Uneven waste disposal can lead to excessive waste accumulation in some areas and less waste in others. Areas with excessive accumulation may suffer from insufficient oxygen supply, preventing complete pyrolysis and gasification, resulting in large amounts of unburned materials and harmful gases, reducing gasification efficiency, and increasing the difficulty and cost of subsequent exhaust gas treatment. Conversely, areas with less waste may experience unstable gasification reactions due to uneven heat distribution, affecting the overall operation of the gasifier.

[0006] Therefore, it is necessary to provide a new moving feeding mechanism for a waste pyrolysis gasification furnace to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a mobile feeding mechanism for a waste pyrolysis gasification furnace.

[0008] The mobile feeding mechanism of the waste pyrolysis gasification furnace provided by this utility model includes: a gasification furnace body, a crushing roller, a hammer, a striking component, and a swinging component. A hopper for holding waste is installed on the top of the gasification furnace body, and a feeder is rotatably installed inside the hopper. Crushing rollers for crushing waste are symmetrically installed inside the hopper. Hammers are symmetrically arranged on both sides of the hopper. A striking component is installed between the hopper and the hammers. The striking component is used to strike the side wall of the hopper to prevent waste from sticking to the inner wall of the hopper and causing accumulation and blockage. A swinging component is installed between the gasification furnace body and the feeder. The swinging component drives the feeder to swing back and forth to evenly spread the waste inside the gasification furnace body.

[0009] Preferably, a motor is fixedly connected to the side wall of the hopper, and the output end of the motor is fixedly connected to the end of one of the shafts of the two crushing rollers. A drive gear is fixedly connected to the end of the shaft, and a driven gear is fixedly connected to the end of the shaft of the other crushing roller. The drive gear and the driven gear are meshed together.

[0010] Preferably, the striking assembly includes: a driving pulley, a driven pulley, and a transmission rod. The driving pulley is fixedly connected to the end of the shaft of each of the two crushing rollers near the motor. The transmission rod is rotatably connected to both sides of the hopper. The driven pulley is fixedly connected to the end of the transmission rod near the motor. The driving pulley and the driven pulley are connected by belt drive. Connecting rods are symmetrically fixedly connected to the outer wall of the transmission rod. The other end of the connecting rod is rotatably connected to the corresponding striking hammer.

[0011] Preferably, the hammer is made of rubber and has a spherical head design at the end.

[0012] Preferably, a conveyor belt is installed inside the hopper near the bottom, and a guide plate is fixedly connected to the end of the conveyor belt near the material discharge point.

[0013] Preferably, the oscillating assembly includes: an electric push rod, a push block, an arc groove, and a guide rod. The electric push rod is fixedly connected to the upper side wall of the gasifier body. The output end of the electric push rod is fixedly connected to the push block, and the push block has a mating groove inside. The side wall of the gasifier body has an arc groove. The side wall of the distributor is fixedly connected to the guide rod, and the other end of the guide rod passes through the arc groove and is placed in the mating groove inside the push block.

[0014] Preferably, the center of the arc-shaped groove coincides with the rotation center of the fabric feeder.

[0015] Compared with related technologies, the moving feeding mechanism of the waste pyrolysis gasification furnace provided by this utility model has the following beneficial effects:

[0016] By setting symmetrically distributed crushing rollers in the hopper and using the meshing transmission of the driving gear and driven gear driven by the motor to achieve synchronous rotation of the two rollers in opposite directions, this design can efficiently squeeze and shear complex waste of different sizes and entanglements, breaking down large pieces of material into smaller and more uniform particles. The flowability of the crushed waste is greatly improved, effectively reducing blockages caused by material jamming and entanglement in the feeding channel, reducing the frequency of equipment maintenance and downtime, and improving the continuous operating efficiency of the waste pyrolysis gasification furnace.

[0017] The power of the crushing roller of the striking component is transmitted through the drive pulley, driven pulley and belt to drive the transmission rod to rotate, which in turn causes the striking hammer to periodically strike the side wall of the hopper in a circular motion; the striking hammer made of rubber and with a spherical head design ensures sufficient striking force to shake off the adhering garbage while avoiding rigid damage to the hopper wall, thereby removing the material adhering to the inner wall of the hopper and ensuring that the discharge channel remains unobstructed for a long time.

[0018] The electric push rod in the swing assembly drives the push block to move. With the guidance of the arc groove and guide rod, the distributor swings back and forth around its own rotation center, evenly distributing the waste inside the gasifier body and avoiding local accumulation. The uniform waste distribution makes the temperature field and airflow field inside the furnace more balanced, allowing the waste to be fully pyrolyzed and gasified, reducing the generation of unburned substances and harmful gases, reducing the load on subsequent exhaust gas treatment, improving the stability of the gasification reaction, and extending the service life of the gasifier.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 4 A mobile feeding mechanism for a waste pyrolysis gasification furnace includes: a gasification furnace body 1, crushing rollers 4, hammers 5, a striking assembly, and a swinging assembly. A hopper 2 for holding waste is installed above the gasification furnace body 1, and a distributor 3 is rotatably installed inside. Crushing rollers 4 for crushing waste are symmetrically installed inside the hopper 2. Hammers 5 are symmetrically arranged on both sides of the hopper 2. A striking assembly is installed between the hopper 2 and the hammers 5 to strike the side walls of the hopper 2, preventing waste from sticking to the inner wall and causing blockage. A swinging assembly is installed between the gasification furnace body 1 and the distributor 3, driving the distributor 3 to swing back and forth to evenly distribute waste inside the gasification furnace body 1. A motor 6 is fixedly connected to the side wall of the hopper 2, and the output end of the motor 6 is fixedly connected to the end of one of the shafts of the two crushing rollers 4. Next, a drive gear 7 is fixedly connected to the end of the shaft, and a driven gear 8 is fixedly connected to the end of the shaft of the other crushing roller 4. The drive gear 7 and the driven gear 8 are meshed together. The striking assembly includes: a drive pulley 9, a driven pulley 10, and a transmission rod 11. The drive pulley 9 is fixedly connected to the end of the shaft of each of the two crushing rollers 4 near the motor 6. The transmission rod 11 is rotatably connected to both sides of the hopper 2. The driven pulley 10 is fixedly connected to the end of the transmission rod 11 near the motor 6. The drive pulley 9 and the driven pulley 10 are connected by belt drive. The outer wall of the transmission rod 11 is symmetrically fixedly connected to a connecting rod 12. The other end of the connecting rod 12 is rotatably connected to the corresponding striking hammer 5. The striking hammer 5 is made of rubber and has a spherical head design at the end. A conveyor belt 13 is installed inside the hopper 2 near the bottom, and a guide plate 14 is fixedly connected to the end of the conveyor belt 13 where the material is discharged.

[0027] It should be noted that: Motor 6 is an existing mature device; when Motor 6 starts, it drives the two crushing rollers 4 to rotate synchronously in opposite directions through the meshing transmission of the driving gear 7 and the driven gear 8; under the action of the protruding structure on the surface of the crushing rollers 4, the garbage in the hopper 2 is gradually squeezed and sheared to achieve preliminary crushing. At the same time, the transmission rod 11 is driven to rotate synchronously through the belt. As the transmission rod 11 continues to rotate, the hammer 5 moves in a circular motion around the transmission rod 11 as the axis, periodically striking the side wall of the hopper 2, shaking off the garbage adhering to the inner wall of the hopper 2, and preventing it from accumulating and clogging.

[0028] Please see Figure 2 and Figure 4 The swing assembly includes an electric push rod 15, a push block 16, an arc groove 17, and a guide rod 18. The electric push rod 15 is fixedly connected to the upper side wall of the gasifier body 1. The output end of the electric push rod 15 is fixedly connected to the push block 16, and the push block 16 has a mating groove inside. The side wall of the gasifier body 1 has an arc groove 17. The side wall of the distributor 3 is fixedly connected to the guide rod 18. The other end of the guide rod 18 passes through the arc groove 17 and is placed in the mating groove inside the push block 16. The center of the arc groove 17 coincides with the rotation center of the distributor 3.

[0029] It should be noted that the electric push rod 15 is an existing mature device; when the electric push rod 15 is started, the push block 16 moves accordingly, pushing the guide rod 18 to slide back and forth in the arc groove 17. The sliding of the guide rod 18 causes the distributor 3 to swing back and forth around its own rotation center, so that the waste inside it is evenly thrown into the interior of the gasifier body 1.

[0030] The working principle of the moving feeding mechanism of the waste pyrolysis gasification furnace provided by this utility model is as follows:

[0031] First, the waste is fed into the hopper 2 located at the top of the gasifier body 1 via a grabbing device. Due to the complex composition of the waste, which includes materials of varying sizes and shapes that are easily entangled, pretreatment is required to avoid clogging. The operator starts the motor 6 installed on the side wall of the hopper 2. The output end of the motor 6 is fixedly connected to the end of the shaft of one of the crushing rollers 4, and a drive gear 7 is also fixedly installed at the end of the shaft. The end of the shaft of the other crushing roller 4 is fixedly connected to a driven gear 8. When the motor 6 is running, the two crushing rollers 4 are driven to rotate synchronously in opposite directions through the meshing transmission of the drive gear 7 and the driven gear 8. Under the action of the raised structure on the surface of the crushing roller 4, the waste in the hopper 2 is gradually squeezed and sheared, achieving preliminary crushing and breaking down large, entangled pieces of waste into materials with smaller particle sizes and more uniform shapes, reducing the risk of clogging during the feeding process.

[0032] As the crushing roller 4 rotates, the drive pulley 9, fixed at the end of its shaft near the motor 6, also rotates. Transmission rods 11 are rotatably connected to both sides of the hopper 2. A driven pulley 10 is fixedly installed at the end of the transmission rod 11 near the motor 6. The drive pulley 9 and the driven pulley 10 are connected by a belt drive. Based on the belt drive principle, the rotational power of the crushing roller 4 is transmitted to the transmission rod 11, causing it to rotate synchronously. Connecting rods 12 are symmetrically fixed to the outer wall of the transmission rod 11, and the other end of the connecting rod 12 is rotatably connected to the corresponding striking hammer 5. As the transmission rod 11 continues to rotate, the striking hammer 5 revolves around the transmission rod 11, periodically striking the side wall of the hopper 2. Because the striking hammer 5 is made of rubber and has a spherical head design, it effectively dislodges debris adhering to the inner wall of the hopper 2 while ensuring striking force, preventing its accumulation and blockage, and avoiding rigid damage to the hopper 2, thus ensuring the structural integrity of the hopper 2. The debris, after being crushed by the crushing roller 4, falls onto the conveyor belt 13 located near the bottom inside the hopper 2. 3. Continuous operation smoothly conveys the waste to the guide plate 14 at the unloading end; the inclined design of the guide plate 14 guides the waste to slide smoothly into the inside of the distributor 3; at this time, the electric push rod 15 installed on the side wall of the gasifier body 1 near the top is activated, and the output end of the electric push rod 15 is fixedly connected to the push block 16, which has a mating groove inside; the side wall of the distributor 3 is fixedly connected to the guide rod 18, and the other end of the guide rod 18 passes through the arc-shaped groove 17 opened on the side wall of the gasifier body 1 and is placed in the mating groove inside the push block 16; when the electric push rod 15 is activated, the waste is smoothly conveyed to the unloading end of the distributor 3. When the push rod 15 extends and retracts, the push block 16 moves accordingly, pushing the guide rod 18 to slide back and forth in the arc-shaped groove 17. Since the center of the arc-shaped groove 17 coincides with the rotation center of the distributor 3, the sliding of the guide rod 18 causes the distributor 3 to swing back and forth around its own rotation center. During this process, the distributor 3 evenly throws the garbage that enters it into the interior of the gasifier body 1, so that the garbage forms a relatively uniform accumulation distribution in the gasifier, effectively avoiding the problem of local accumulation and providing a good material basis for the subsequent pyrolysis gasification reaction.

[0033] After the material is laid, the gasifier body 1 is started. In a high-temperature, oxygen-deficient environment, the uniformly distributed waste inside is pyrolyzed and gasified, converting the waste into combustible gas, liquid products and solid carbon and other resource-based products, thus achieving efficient waste treatment and resource recycling.
