[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses a high-efficiency incineration structure of an incinerator. Example

[0034] Reference Figure 1 An incinerator with high efficiency incineration structure includes a body 1, which is provided with a feeding component 2, a drying component 3, a combustion component 4 and a burnout component 5. The feeding component 2, the drying component 3, the combustion component 4 and the burnout component 5 are connected together in sequence from high to low. When the incineration structure is in use, garbage is added from the feeding component 2, and the feeding component 2 pushes the garbage onto the drying component 3.

[0035] Reference Figure 1 The feeding assembly 2 includes a first hydraulic cylinder 21 fixedly connected to the machine body 1. The output end of the first hydraulic cylinder 21 is fixedly connected to a push plate 22. The garbage falls from above the push plate 22 and falls to the push plate 22. The first hydraulic cylinder 21 drives the push plate 22 to move back and forth, and pushes the garbage onto the drying assembly 3. Baffles 23 are fixedly connected to both sides of the push plate 22. The baffles 23 block the garbage and prevent the garbage from scattering from both sides to the outside of the machine body 1. When the first hydraulic cylinder 21 drives the push plate 22 to move back and forth, an inclined receiving plate 24 is fixedly connected to the upper end of the push plate 22. The receiving plate 24 receives the falling garbage and ensures that the garbage falls into the push plate 22, preventing the garbage from contacting the first hydraulic cylinder 21. The receiving plate 24 ensures that the garbage falls into the push plate 22.

[0036] Reference Figure 1 and Figure 2The drying assembly 3, the combustion assembly 4 and the burnout assembly 5 all include a plurality of movable grates 6 and a plurality of fixed grates 7, and the movable grates 6 and the fixed grates 7 are arranged alternately. The machine body 1 is fixed with a first column, a second column and a third column, and the first column corresponds to the drying assembly 3, the second column corresponds to the combustion assembly 4, and the third column corresponds to the burnout assembly 5. The drying assembly 3, the combustion assembly 4 and the burnout assembly 5 are all connected with a driving assembly 8 that drives the movable grates 6 thereof to reciprocate, and the driving assembly 8 includes a second hydraulic cylinder and a transmission rod, and the output end of the second hydraulic cylinder is fixedly connected to the transmission rod, and the three second hydraulic cylinders are respectively mounted on the first column, the second column and the third column.

[0037] Reference Figure 1 and Figure 2 The movable grates 6 of the drying component 3 are fixedly connected to the transmission rod below them, the movable grates 6 of the combustion component 4 are fixedly connected to the transmission rod below them, and the movable grates 6 of the burnout component 5 are fixedly connected to the transmission rod below them. Then, the reciprocating movement of the output ends of the three second hydraulic cylinders can drive all the movable grates 6 on the drying component 3, the combustion component 4 and the burnout component 5 to move back and forth, thereby moving the garbage downward on the grate.

[0038] Reference Figure 1 and Figure 2 During the use of the incineration structure, garbage is added from the feeding component 2, and the feeding component 2 pushes the garbage to the drying component 3. The movable grate 6 and the fixed grate 7 on the drying component 3 dry the garbage. The driving component 8 then drives all the movable grates 6 on the drying component 3 to reciprocate and transport the garbage to the combustion component 4. The movable grate 6 and the fixed grate 7 on the combustion component 4 burn the garbage. The driving component 8 then drives all the movable grates 6 on the combustion component 4 to reciprocate and transport the burned garbage to the burnout component 5. The movable grate 6 and the fixed grate 7 on the burnout component 5 re-burn and transport the garbage.

[0039] Reference Figure 1 and Figure 2The fixed grate 7 and the movable grate 6 are all tilted, so that the drying component 3, the combustion component 4 and the burnout component 5 are all tilted downward, ensuring that the garbage is transported from a high place to a low place under the action of gravity, ensuring the combustion and transportation of the garbage, reducing the driving force of the driving component 8, reducing energy consumption, and saving production resources. The body 1 is fixed with a slag bucket 25, and the ash and slag after the garbage is completely burned fall from the burnout component 5 into the slag bucket 25. The slag bucket 25 is located at the end of the body 1 away from the feeding component 2. The slag bucket 25 corresponds to the burnout component 5. A conveyor belt 26 is installed in the slag bucket 25. The slag bucket 25 is fixed with a motor 27 that drives the conveyor belt 26 to rotate. The motor 27 drives the conveyor belt 26 to rotate. A slag discharge port 28 is opened on one side of the slag bucket 25, and then the conveyor belt 26 transports the ash and slag to the slag discharge port 28 for falling. The slag bucket 25 and the conveyor belt 26 collect and process the ash and slag in a centralized manner.

[0040] Reference Figure 1 and Figure 3 When the active grate 6 of the drying component 3, the combustion component 4 and the burnout component 5 transport the garbage, the active grate 6 (refer to Figure 2 ) include three mutually parallel first grate plates 9 (refer to Figure 2 ), fixed grate 7 (refer to Figure 2 ) include three mutually parallel second grate plates 10 (refer to Figure 2 ), the first grate piece 9 (refer to Figure 2 ) are equipped with shear blades 11. The first grate sheet 9 (refer to Figure 2 ) cuts and crushes the thicker layer of garbage, so that the garbage layer is distributed more evenly. The cut garbage can be fully in contact with the air, which speeds up the burning speed of the garbage, makes the garbage burn faster and more fully, and improves the incineration efficiency of the garbage. At the same time, the garbage can be cut to improve the distribution of the garbage in the incinerator, which is conducive to the full combustion of the garbage. There are height differences between the drying component 3 and the combustion component 4, and between the combustion component 4 and the burnout component 5. The garbage will also have a certain crushing effect when it falls, which is conducive to the full combustion of the garbage.

[0041] Refer to 2 and Figure 3 The shearing knife 11 is provided with a blade portion 12. When the first grate slice 9 is reciprocating, the blade portion 12 cuts and crushes the thick garbage accumulated on the upper material layer of the movable grate 6 and the fixed grate 7, which has a good cutting and crushing effect on the garbage, and is convenient for ensuring the full combustion of the garbage. The angle between the blade portion 12 and the upper end surface of the first grate slice 9 is 120 degrees, which ensures that the movable grate 6 will not be stuck by hard foreign objects in the garbage when the first grate slice 9 is reciprocating, which is convenient for ensuring the normal use of the shearing knife 11 and improving the incineration efficiency of the garbage.

[0042] Refer to 2 and Figure 3 The first grate plate 9 is provided with a first inclined portion 13, the end of the shearing knife 11 away from the blade portion 12 is provided with a second inclined portion 14, the lower end of the second inclined portion 14 and the upper end of the first inclined portion 13 are located on the same straight line, the driving assembly 8 (refer to Figure 1 ) When the first grate plate 9 is driven to move back and forth, the angle formed by the first inclined portion 13 and the second inclined portion 14 is an obtuse angle, which is 150 degrees, so that the first inclined portion 13 and the second inclined portion 14 have a pushing effect on the garbage, preventing the garbage from piling up on the fixed grate 7 and the movable grate 6.

[0043] Refer to 2 and Figure 3 The first grate sheet 9 is provided with an inclined groove 15 matched with the shearing knife 11, and the lower end of the shearing knife 11 is located in the inclined groove 15. When the shearing knife 11 is connected and installed with the first grate sheet 9, the operator inserts the lower end of the shearing knife 11 into the inclined groove 15. A graphite pad 29 is installed at the connection between the lower end of the shearing knife 11 and the inclined groove 15. The graphite pad 29 has good thermal stability, chemical corrosion resistance, good compression and resilience, and small thermal stress relaxation, which can improve the sealing between the shearing knife 11 and the inclined groove 15 and prevent ash and slag from falling into the inclined groove 15.

[0044] Reference Figure 3 and Figure 4 The lower end surface of the first grate plate 9 is fixed with positioning blocks 16 located on both sides of the inclined groove 15, and the positioning blocks 16 are each provided with a first through groove 17. The lower end of the shearing knife 11 is provided with a second through groove matched with the first through groove 17. The positioning block 16 is connected to a connecting plate 19 matched with the first through groove 17, and then the connecting plate 19 is sequentially passed through the first through groove 17, the second through groove of the positioning block 16 on one side and the first through groove 17 of the positioning block 16 on the other side.

[0045] Reference Figure 3 and Figure 4 The lower end of the shearing knife 11 and the positioning block 16 are connected with three bolts 20, and the connecting plate 19 is provided with a plurality of screw holes matched with the bolts 20. Finally, the bolts 20 are threadedly connected with the screw holes corresponding to the shearing knife 11, so that the shearing knife 11 and the first grate sheet 9 are installed together, so that the lower end of the shearing knife 11 and the first grate sheet 9 can be disassembled, which is convenient for replacing and overhauling the shearing knife 11.

[0046] The implementation principle of the efficient incineration structure of an incinerator in the embodiment of the present application is as follows: when the incineration structure is in use, garbage falls from above the push plate 22, and the first hydraulic cylinder 21 drives the push plate 22 to move back and forth, pushing the garbage onto the drying component 3, and the driving component 8 drives the movable grate 6 to move back and forth, so that the garbage is transported from the drying component 3 to the combustion component 4, and then transported from the combustion component 4 to the burnout component 5. When the drying component 3, the combustion component 4 and the movable grate 6 of the burnout component 5 transport the garbage, the shear knife 11 on the first grate plate 9 cuts and crushes the garbage with a thicker material layer, so that the garbage material layer is distributed more evenly. The cut garbage can be fully in contact with the air, which speeds up the combustion speed of the garbage, makes the garbage burn faster and more fully, and improves the incineration efficiency of the garbage.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
