Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage incineration power generation, in particular to a garbage feeding device for garbage incineration power generation. Background Art
[0002] Waste incineration power generation is a new type of waste disposal method. It can not only process the waste generated in daily life, but also use the heat generated during the incineration process to generate electricity for daily power supply. During the waste incineration process, equipment is needed to bring the waste to the incinerator.
[0003] Therefore, after searching, a garbage feeding system for a garbage incineration power plant in the prior art is found, with the publication number: CN218796182U. The garbage to be incinerated is grabbed by a grab bucket and sent to a feed hopper. The garbage falls downward into the conveying shell under the action of gravity, and the crushing component crushes the garbage. During the whole process of garbage transportation, the leachate contained in the garbage can leak out through the filtrate holes, thereby enhancing the effect of removing moisture from the garbage. When the filtrate holes need to be cleaned, the bristles of the cleaning plate clean the filtrate holes of the lower shell during movement. At the same time, the cleaning plate is arranged in the liquid collecting bin and is driven to move by the driving component, thereby avoiding the need to stop the feeding work of the feeding system to clean the filtrate holes.
[0004] However, when the existing patent is in use, when the crushed garbage is pushed in the auger, the moisture inside it is completely discharged through the filter liquid holes by gravity. Therefore, the leachate adsorbed in the garbage itself cannot be discharged in time, resulting in imperfect moisture treatment of the garbage entering the incinerator. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] 1. In the utility model, garbage is dropped to one side of the processing box through a clamp or a screw conveyor of the prior art, and falls on a belt conveyor. The belt conveyor is used to move the garbage in the processing box, and passes through a dehydration chamber, a cutting chamber, a drying chamber and a crushing chamber in sequence.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] like Figure 1-4As shown, the garbage feeding device for garbage incineration power generation comprises a processing box 1, and a belt conveyor 6 for transporting garbage is arranged at the bottom of the processing box 1. The garbage falls to one side of the processing box 1 through a clamp or a screw conveyor of the prior art, and falls on the belt conveyor 6. The operation of the belt conveyor 6 realizes the movement of the garbage in the processing box 1. The processing box 1 is provided with four chambers, which are a dehydration chamber 2 for squeezing and dehydrating the garbage, a cutting chamber 3 for cutting the garbage after dehydration, a drying chamber 4 for drying the garbage after cutting, and a drying chamber 5 for drying the garbage after drying. The garbage falling on one side of the processing box 1 is sequentially passed through the dehydration chamber 2, the cutting chamber 3, the drying chamber 4 and the crushing chamber 5 by the belt conveyor 6. The garbage is squeezed into blocks and dehydrated in the dehydration chamber 2. The extruded blocks of garbage are cut into small pieces in the cutting chamber 3. The cut small pieces of garbage are dried in the drying chamber 4. The dried small pieces of garbage are dispersed by vibration in the crushing chamber 5. Finally, the crushed and dried garbage is transported to the garbage incinerator for incineration and power generation under the transportation action of the belt conveyor 6:
[0024] Further discussion: An extrusion plate 9 is slidably connected to the cavity wall on one side of the dehydration cavity 2, and the cavity wall on the other side is hollow. A guide rod 8 penetrating the wall of the processing box 1 is fixedly connected at a corner of one side of the extrusion plate 9, and an electric telescopic rod 7 for driving the extrusion plate 9 to move is fixedly connected to the wall of the processing box 1. The limiting effect of the guide rod 8 on one side of the extrusion plate 9 and the pushing effect of the electric telescopic rod 7 on one side of the extrusion plate 9 are utilized to realize the sliding of the extrusion plate 9, and the garbage falling into the dehydration cavity 2 is squeezed and dehydrated. The processing box 1 is respectively provided with a cutting knife 10, a heating plate 11 and an elastic vibration plate 12 at the positions of the cutting cavity 3, the drying cavity 4 and the crushing cavity 5. The heating plate 11 is heated by steam or by electric heating wire. After the heating plate 11 is inserted into the garbage, the garbage is quickly dried. The elastic vibration plate 12 is made of elastic material and And by installing a vibration motor in the elastic vibration plate 12, the vibration motor is used to start the elastic vibration plate 12 to vibrate, so that when the elastic vibration plate 12 is inserted into the dried garbage, the garbage is dispersed by vibration, and the cutting knife 10, the heating plate 11 and the elastic vibration plate 12 are all arranged in a grid shape, and the outer box walls on both sides of the processing box 1 are located at the cutting knife 10, the heating plate 11 and the elastic vibration plate 12. A plurality of electric telescopic rods 7 are fixedly connected, and the cutting knife 10, the heating plate 11 and the elastic vibration plate 12 are fixedly connected to the telescopic ends of the electric telescopic rods 7 at corresponding positions. By contracting the electric telescopic rods 7 at corresponding positions outside the processing box 1, the cutting knife 10, the heating plate 11 and the elastic vibration plate 12 connected to the telescopic ends of the electric telescopic rods 7 at this position can be realized. Enter the cutting chamber 3, the drying chamber 4 and the crushing chamber 5 correspondingly:
[0025] Further discussion: Partitions 13 are provided on the dehydration chamber 2 and the cutting chamber 3, the cutting chamber 3 and the drying chamber 4, the drying chamber 4 and the crushing chamber 5, and the other side of the crushing chamber 5. The partitions 13 are used to separate the space in the processing box 1 to ensure that the garbage does not interfere with each other during dehydration, cutting, drying and dispersion. In addition, the partitions 13 are slid open to move the garbage in the processing box 1, thereby realizing the dehydration, cutting, drying and dispersion of the garbage in turn. The partitions 13 are plugged into the box walls on both sides of the processing box 1, and the outer wall of one side of the processing box 1 is fixedly connected with an elastic The spring rod 20, the telescopic end of the spring rod 20 is fixedly connected with a sealing strip 21 for plugging with the wall of the processing box 1. Under the elastic pushing action of the spring rod 20, the sealing strip 21 is closely attached to one side of the partition 13. Then, when the partition 13 moves to conduct the space inside the processing box 1, the sealing strip 21 moves with the movement and opening of the partition 13 until the sealing strip 21 is embedded in the processing box 1 and plugged with the partition 13. When the partition 13 slides open, garbage is prevented from entering the wall of the processing box 1, causing the partition 13 to be unable to be smoothly inserted into the wall of the processing box 1 when it is reset:
[0026] Further discussion: A screw rod 14 that is threadedly penetrated by the partition 13 is rotatably connected to the box opening of the processing box 1, and the sliding of the partition 13 is achieved by rotating the screw rod 14. A rotating shaft 15 for driving the screw rod 14 to rotate is rotatably connected to the top edge of the box wall on the other side of the processing box 1. A motor (drawn in the figure but not numbered) for driving the rotating shaft 15 to rotate is installed on one side of the processing box 1. A rubber ring 16 is fixedly connected to the rotating shaft 15 at the position of the screw rod 14 and the end face of the screw rod 14 close to the rotating shaft 15. The edge of the rubber ring 16 can be set to have an uneven tooth groove shape. A slide plate 17 is inserted into the box wall on the other side of the processing box 1 at the position of the rubber ring 16. An electric telescopic rod 7 is fixedly connected to the outer wall of the processing box 1 at the position of the slide plate 17, and the electric telescopic rod 7 at the position of the slide plate 17 is used to drive the slide plate 17 to slide. By extending and retracting the electric telescopic rod 7 at this position on the box wall of the processing box 1, the slide plate 17 can slide relative to the processing box 1, so that the rotational force of the rotating shaft 15 can be transmitted to the screw rod 14, and drives the screw rod 14 to rotate, so that the partition 13 slides. The specific scheme is as follows: one side of the slide plate 17 is rotatably connected with two sprocket wheels 19 driven by a chain, and the end faces of the sprocket wheels 19 located on the other side of the slide plate 17 are fixedly connected with bevel gears 18. The two bevel gears 18 correspond to the positions of the rotating shaft 15 and the rubber rings 16 on the screw rod 14 one by one, and are embedded and matched. Therefore, when the slide plate 17 moves to the two bevel gears 18 on the other side and respectively engage with the rotating shaft 15 and the rubber rings 16 on the screw rod 14, the two sprocket wheels 19 connected by the chain, when the rotating shaft 15 rotates, the rubber ring 16 on its surface will rotate, thereby realizing the rotation of the bevel gear 18 engaged with the rubber ring 16 on the rotating shaft 15 and the sprocket wheel 19 at the corresponding position, and under the transmission action of the chain, the other sprocket wheel 19 drives the bevel gear 18 at the corresponding position to rotate, so that the rubber ring 16 on the screw rod 14 rotates, and then the screw rod 14 rotates, and the partition 13 threadedly connected to the screw rod 14 can be moved and opened.
[0027] In the method of use, after dumping the garbage into the dehydration chamber 2, the extrusion plate 9 is used to squeeze and dehydrate the garbage and form it into blocks. Then, the slide plate 17 located between the dehydration chamber 2 and the cutting chamber 3 moves toward the wall of the processing box 1, so that the two bevel gears 18 on the slide plate 17 are respectively engaged with the rotating shaft 15 and the rubber ring 16 on the screw rod 14 located between the dehydration chamber 2 and the cutting chamber 3. The rotation of the rotating shaft 15 drives the rubber ring 16 on its surface to rotate, thereby realizing the rotation of the bevel gear 18 engaged with the rubber ring 16 on the rotating shaft 15 and the sprocket 19 at the corresponding position. Under the transmission action of the chain, another sprocket 19 drives the bevel gear 18 at the corresponding position to rotate, realizing the screw rod 14 located between the dehydration chamber 2 and the cutting chamber 3. The rubber ring 16 on the upper part rotates, thereby realizing the rotation of the screw rod 14 located between the dehydration chamber 2 and the cutting chamber 3, so that the partition 13 located between the dehydration chamber 2 and the cutting chamber 3 can be moved and opened. Under the action of the belt conveyor 6, the garbage squeezed into blocks enters the cutting chamber 3, and then the rotating shaft 15 is reversed to realize the re-closing of the partition 13 between the dehydration chamber 2 and the cutting chamber 3. After being cut into blocks in the cutting chamber 3, the partition 13 between the cutting chamber 3 and the drying chamber 4 is opened in the above manner, and the cut garbage enters the drying chamber 4 for drying. By analogy, the garbage passes through the dehydration chamber 2, the cutting chamber 3, the drying chamber 4 and the crushing chamber 5 in turn, ensuring that the garbage entering the incinerator is dry and dispersed.
[0028] The wiring diagram of the belt conveyor 6, the electric telescopic rod 7, and the heating plate 11 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the belt conveyor 6, the electric telescopic rod 7, and the heating plate 11 are no longer explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
