[0055] In this embodiment, an enlarged opening 1 is provided to facilitate the feeding of domestic waste.

[0056] In this embodiment, during the specific implementation, the structure of the lower silo 3 can refer to the structure of the middle silo 2, but the difference is that the outer edge of the lower connecting plate 2-2 of the middle silo 2 extends out of the outer wall of the outer circular silo plate 2-10, and the bottom of the lower silo 3 is flush with the outer wall of the lower silo 3.

[0057] In this embodiment, the number of the mounting holes on the rear side wall of the lower silo 3 is the same as the number of the unloading rollers 5 and corresponds one to one.

[0058] In the present embodiment, it should be noted that the front mounting port of the lower silo 3, the inspection opening 3-8 and the mounting hole for the unloading roller 5 all need to be sealed with a sealing plate so that the side wall of the lower silo 3 is hollow to form a second cavity, which will not cause the loss of cooling water introduced into the second cavity.

[0059] In this embodiment, the maintenance opening 3-8 is provided to facilitate maintenance of the material discharging roller 5 to ensure normal material discharging of domestic waste. In actual use, the maintenance opening 3-8 is provided with a door panel through a hinge to facilitate opening for maintenance and relatively sealed material discharging when not undergoing maintenance.

[0060] In this embodiment, during specific implementation, the top of the lower silo 3 is an upper top plate 3-1, a lower water inlet 3-3 and a lower water return port 3-4 are provided on the outer side wall of the lower silo 3, and a middle partition plate located between the lower water inlet 3-3 and the lower water return port 3-4 is provided in the second cavity. A first baffle 3-6 and a second baffle 3-7 are provided in the second cavity, and the structures of the first baffle 3-6 and the second baffle 3-7 refer to the upper baffle 2-6 and the lower baffle 2-7.

[0061] In this embodiment, during specific implementation, the upper top plate 3-1 of the lower silo 3 is connected to the lower connecting plate 2-2 of the middle silo 2, the upper connecting plate 2-1 of the middle silo 2 is connected to the bottom of the upper silo 4, and the bottom of the lower silo 3 is installed on the top of the domestic waste pyrolysis / incineration furnace.

[0062] In this embodiment, during the specific implementation, both sides of the middle partition plate 2-5, the upper baffle plate 2-6 and the lower baffle plate 2-7 are in contact with the outer side wall of the inner circular bin plate 2-9 and the inner side wall of the outer circular bin plate 2-10.

[0063] In this embodiment, during the specific implementation, the middle partition 2-5 is set to isolate the middle water inlet 2-3 and the middle water return port 2-4, so as to increase the flow length and time of the cooling water entering the first cavity in the middle silo 2, thereby increasing the cooling effect; in addition, by setting the upper baffle 2-6 and the lower baffle 2-7, the cooling water can flow evenly, which improves the uniformity of cooling the silo wall of the middle silo 2, increases the flow velocity in the cavity, increases the degree of turbulence, and achieves the improvement of the heat transfer effect.

[0064] In this embodiment, during the specific implementation, conical teeth 5-2 and cylindrical teeth 5-3 are set and staggered and spaced to achieve the staggering of large teeth and small teeth. During the pushing process of domestic garbage, the conical teeth 5-2 do not hang on the material, thereby improving the smoothness of material discharge; the cylindrical teeth 5-3 have strong hanging ability, which ensures the ability to grab the material when the domestic garbage is discharged, thereby ensuring the ability of the discharge roller 5 to grab the material and ensuring that the discharge roller 5 can be scraped by the teeth after one rotation, thereby avoiding the garbage from building up on the hollow shaft of the discharge roller 5.

[0065] In this embodiment, during the specific implementation, multiple unloading rollers 5 are set to adapt to the length direction layout of the lower silo 3 and the top of the domestic waste pyrolysis / incineration furnace, so that the domestic waste can be evenly unloaded through the multiple unloading rollers 5; and it is suitable for the unloading requirements of the furnace body with different daily domestic waste processing volumes.

[0066] In this embodiment, it should be noted that: Figure 1 Only three unloading rollers 5 are shown in the figure. In actual use, the number of unloading rollers 5 can be adjusted as needed.

[0067] In this embodiment, it should be noted that the power parts can be staggered along the front and rear side walls of the lower silo 3. By staggering the front and rear of two adjacent power parts, the two adjacent unloading rollers 5 can be arranged in parallel and close to each other, which can not only effectively adjust the installation distance between the two unloading rollers 5, but also save installation space.

[0068] In this embodiment, the middle silo 2 is provided to cool the interior of the middle silo 2 by introducing cooling water into the first cavity, so as to prevent the domestic garbage from easily agglomerating due to the high temperature when passing through the middle silo 2, thereby affecting the garbage discharge speed; in addition, it cooperates with the upper silo 4 to realize continuous storage and discharge of domestic garbage, thereby increasing the discharge amount;

[0069] Secondly, the lower silo 3 is provided in order to introduce cooling water through the second cavity so that the domestic garbage can be continuously cooled when the unloading roller 5 pushes it, thereby auxiliaryly reducing the internal temperature of the silo, avoiding garbage bridging and overhead, and structurally being able to stably supply garbage into the domestic garbage pyrolysis / incineration furnace.

[0070] In this embodiment, the hollow shaft 5-1 is provided for passing cooling water, which can not only assist the water cooling of the lower silo 3 to reduce the internal temperature of the lower silo 3 and avoid the problems of garbage bridging and overhead, but also avoid excessive temperature and deformation or aging of the unloading roller 5, which in turn affects the subsequent enlargement or reduction of the rear axle spacing, resulting in leakage or jamming.

[0071] In this embodiment, in actual use, the other end of the hollow shaft 5 - 1 passing through the end of the mounting hole of the lower silo 3 is provided with a seat bearing, and the seat bearing is arranged on the outer side wall of the lower silo 3 .

[0072] In this embodiment, the lower end of the inclined baffle 2-8 fits the top surface of the blocking block 3-2, and the inclined baffle 2-8 and the blocking block 3-2 cooperate to allow the domestic waste entering the lower silo 3 to be close to the middle, thereby avoiding the problem of domestic waste gathering at the side wall of the silo and being unable to be discharged.

[0073] In this embodiment, it should be noted that the length of the coarsely crushed domestic waste is greater than the net distance between two adjacent discharge rollers 5 and less than the axial distance between the two discharge rollers 5 .

[0074] In this embodiment, it should be noted that the cooling water is tap water at room temperature.

[0075] Example 2

[0076] A method for using a domestic waste pyrolysis / incineration furnace feeding system with a cooling function, comprising the following steps:

[0077] The grab bucket grabs the coarsely crushed domestic garbage into the enlarged opening 1, and the domestic garbage entering the enlarged opening 1 passes through the upper silo 4 and the middle silo 2 and enters the lower silo 3. When the domestic garbage enters the lower silo 3, the synchronous power motor 6 works, and the power motor 6 drives the unloading roller 5 to rotate through the reducer 7. The unloading roller 5 rotates to push the domestic garbage entering the lower silo 3 and falls through the gap between two adjacent unloading rollers 5 into the domestic garbage pyrolysis / incineration furnace;

[0078] At the same time, during the discharge of domestic waste, cooling water is introduced into the first cavity of the middle silo 2 through the middle water inlet 2-3, and the cooling water cools the inside of the middle silo 2 and is collected through the middle water return port 2-4;

[0079] Cooling water is introduced into the second cavity of the lower silo 3 through the lower water inlet 3-3, and the cooling water cools the interior of the lower silo 3 and is collected through the lower water return port 3-4;

[0080] Cooling water is introduced into one end of the hollow shaft 5-1, and the cooling water cools the hollow shaft 5-1 and is collected through the other end of the hollow shaft 5-1.

[0081] In this embodiment, the specific implementation is that in the process that the unloading roller 5 rotates to push the domestic waste entering the lower silo 3 and falls through the gap between two adjacent unloading rollers 5 into the domestic waste pyrolysis / incineration furnace, the multiple unloading rollers 5 are sequentially recorded from the left end to the right end as the first unloading roller, ..., the i-th unloading roller, ..., the I-th unloading roller, i and I are both positive integers, and 1≤i≤I;

[0082] When I is an even number, first operate when i is an odd number between 1 and I-1, the i-th feed roller rotates clockwise, and the i+1-th feed roller rotates counterclockwise until the set rotation time is reached; then operate when i is an even number between 2 and I-2, the i-th feed roller rotates clockwise, and the i+1-th feed roller rotates counterclockwise until the set rotation time is reached, and repeat the reciprocating process multiple times to evenly feed the materials; wherein the set rotation time is 20s to 30s;

[0083] When I is an odd number, first operate when i is an odd number between 1 and I-2, the i-th feed roller rotates clockwise, and the i+1-th feed roller rotates counterclockwise, until the set rotation time is reached; then operate when i is an even number between 2 and I-1, the i-th feed roller rotates clockwise, and the i+1-th feed roller rotates counterclockwise, until the set rotation time is reached, and repeat this reciprocating process for multiple times to ensure uniform feed discharge; wherein the set rotation time is 20s to 30s.

[0084] In summary, the present invention is reasonably designed and can not only realize the cooling of the interior of the silo, but also meet the cooling of the discharge shaft, solve the problems of garbage bridging and overhead heating, and deformation and aging of the discharge shaft, thereby improving the continuous operation time of the discharge.

[0085] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
