[0017] The beneficial effects of the present invention:

[0018] (1) In the present invention, the puncture needle on the movable plate punctures above the partition plate, piercing the bag or bottle, causing the sewage to fall into the drain pipe and finally being collected in the liquid collection tank, effectively separating the sewage from the garbage, preventing the sewage from entering the cracking furnace, not only protecting the metal components of the cracking furnace from corrosion by acid-base substances, but also keeping the temperature inside the cracking furnace uniform, improving the efficiency and stability of the cracking reaction;

After the garbage is punctured and extruded, the movable plates gradually reset. At first, the perforated plate cannot move, and the puncture needle passes through the holes on the perforated plate, which can remove the garbage attached to the puncture needle, facilitating subsequent punctures. When the pulling force is greater than the suction force between the magnetic strips, the perforated plate will fit the movable plate again;

[0020] (3) In the present invention, by setting the partition plate to be movable, when puncturing the garbage, the two partition plates automatically open under the action of the driving mechanism, facilitating the fall of the sewage. And at this time, due to the pressure, the garbage will not fall, allowing enough time for the sewage to be drained, reducing the sewage residue in the garbage. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The accompanying drawings are only for illustrative purposes and should not be construed as limiting the present invention; for better illustrating this embodiment, some components in the drawings are omitted, enlarged or reduced, and do not represent the size and shape of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 4As shown in the figure, the present invention is an automatic feeding device for a high-temperature pyrolysis furnace of domestic waste, including a feeding box 1 with an open top and a spiral feeding pipe 2 connected to the bottom of the feeding box 1. A camera 5 is installed on one inner wall of the feeding box 1. A spiral shaft 6 is rotatably installed in the spiral feeding pipe 2. The bottom of the spiral feeding pipe 2 is connected with a plurality of drain pipes 3. One ends of the plurality of drain pipes 3 are commonly connected to a liquid collecting box 4. Rectangular holes are provided on both side walls of the feeding box 1. Partition plates 7 are provided in the rectangular holes on both sides. Puncturing mechanisms 9 are provided above the partition plates 7. The puncturing mechanism 9 includes a movable plate 901. One side of the movable plate 901 is connected with a driving rod 8. The driving rod 8 is connected to an external driving source. Puncturing needles 903 are arranged in an array on the side wall of the movable plate 901. A driving mechanism is arranged between the movable plate 901 and the partition plate 7. The domestic waste can be intermittently conveyed into the feeding box 1 by a conveyor belt. The camera 5 is installed in the feeding box 1 to facilitate the operator to observe the amount of waste. When an appropriate amount of waste is loaded into the feeding box 1, the conveying is stopped. The external driving source drives the movable plates 901 on both sides to approach each other. The bags and bottles are punctured and the waste is squeezed by the puncturing needles 903 to accelerate the discharge of sewage. And under the action of the driving mechanism, the two partition plates 7 can move away from each other, which will not hinder the falling of sewage. Under the action of pressure, the waste cannot fall smoothly, so that the sewage has sufficient time to be drained completely.

[0035] Referring to Figure 4 , mounting holes are symmetrically formed on the side wall of the movable plate 901. A first spring 904 is connected in the mounting hole. One ends of the two first springs 904 are commonly connected to a perforated plate 902. And the holes of the perforated plate 902 correspond to the positions of the puncturing needles 903 one by one. Fixing columns 905 are symmetrically connected to the side wall of the perforated plate 902 away from the movable plate 901. One end of the fixing column 905 is connected with a magnetic strip 906. Since some waste may hang on the puncturing needles 903, when the movable plates 901 on both sides gradually approach, the magnetic strips 906 on both sides are attached and adsorbed, temporarily fixing the positions of the two perforated plates 902. After the puncturing and squeezing are completed, the two movable plates 901 are reset. And due to the fixed position of the perforated plate 902, the movable plate 901 will drive the puncturing needles 903 to pass through the holes on the perforated plate 902, scraping the waste attached to the puncturing needles 903, and the puncturing needles 903 can also be straightened. When the pulling force is greater than the suction force of the magnetic strips 906 on both sides, under the action of the first spring 904, the perforated plate 902 is reset, which is beneficial to the next puncturing. The magnetic strip 906 is made of a magnet, and the magnetic strips 906 on both sides have different magnetic polarities.

[0036] Referring to Figures 5 to 8As shown in the figure, a guide hole is formed in the partition plate 7, and a guide rod 11 is movably arranged in the guide hole. One end of the guide rod 11 is fixed with an L-shaped rod 10, and one end of the L-shaped rod 10 is fixed on the side wall of the feed box 1. A second spring 12 is sleeved on the guide rod 11, and the second spring 12 is located between the L-shaped rod 10 and the partition plate 7. A long strip hole 13 is formed in the partition plate 7. The driving mechanism includes a movable rod 14. A connecting rod is fixed on the movable rod 14. One end of the connecting rod penetrates through the long strip hole 13 and is fixedly connected with the movable plate 901. A plurality of first mounting brackets 18 are uniformly arranged on the upper surface of the movable rod 14 along the length direction. A plurality of ratchet teeth 19 are mounted on the first mounting brackets 18. A third spring 20 is connected to the ratchet teeth 19. One end of the third spring 20 is connected with the movable rod 14. A second mounting bracket 15 is mounted on the lower surface of the partition plate 7. A ratchet wheel 16 and a gear 31 are fixedly mounted on the mounting shaft of the second mounting bracket 15. A rack 17 is mounted on the lower surface of the partition plate 7. The rack 17 meshes with the gear 31. A limiting rod 21 is mounted on the first mounting bracket 18. The limiting rod 21 contacts the upper surface of the ratchet teeth 19. The driving mechanisms on the two partition plates 7 are arranged staggeredly. Initially, the two partition plates 7 are attached to each other. When the two movable plates 901 approach each other, the movable rod 14 is driven to move together through the connecting rod. When the first ratchet tooth 19 contacts the ratchet wheel 16, the ratchet wheel 16 is driven to rotate, so that the gear 31 rotates. The gear 31 meshes with the rack 17, so that the two partition plates 7 move away from each other along the guide rod 11. At this time, the garbage has been squeezed to a certain extent and will not fall, while the sewage can be quickly discharged. And when the movable plate 901 is reset, the ratchet teeth 19 cannot drive the ratchet wheel 16 to rotate after passing through the ratchet wheel 16.

[0037] Refer to Figure 9, a push rod 23 is fixed on the side wall of the movable plate 901 away from the puncture needle 903, a magnetic member 22 is fixed on one side of the partition plate 7, a movable ring 24 is movably sleeved on the L-shaped rod 10, a movable shaft 25 is fixed between two movable rings 24 on the same side, a movable block 26 is fixed on the movable shaft 25, an adsorbing member 28 is fixed on the movable block 26, a wedge block 29 is fixed on the top of the adsorbing member 28, the bottom of the movable block 26 is connected with a fourth spring 27, one end of the fourth spring 27 is fixed with a cross bar 30, and both ends of the cross bar 30 are respectively fixed on two L-shaped rods 10; when the two movable plates 901 approach each other, the push rod 23 disengages from the wedge block 29, under the action of the fourth spring 27, the movable ring 24, the movable shaft 25, the movable block 26, the adsorbing member 28 and the wedge block 29 rise, so that the adsorbing member 28 and the magnetic member 22 are at the same height. After the two partition plates 7 move away from each other, the magnetic member 22 contacts the adsorbing member 28 to fix the position of the partition plate 7. In this way, when the movable plate 901 resets, the garbage can automatically fall from between the two partition plates 7. When the movable plate 901 is completely reset, the push rod 23 presses the wedge block 29 to separate the adsorbing member 28 from the magnetic member 22. Under the action of the second spring 12, the partition plate 7 also automatically resets, which is convenient for subsequent garbage disposal. The magnetic member 22 is made of a magnet, and the adsorbing member 28 is made of an iron material.

[0038] The working principle of the present invention: Initially, the two partition plates 7 are in contact with each other. One end of the spiral feed pipe 2 is docked with the feed port of the cracking furnace. The domestic garbage is intermittently conveyed into the feed box 1 by a conveyor belt (not shown). A camera 5 is installed in the feed box 1 to facilitate the operator to view the amount of garbage. When an appropriate amount of garbage is loaded on the two partition plates 7, the conveying stops. The external drive source (not shown) drives the movable plates 901 on both sides to approach each other. The puncture needle 903 is used to puncture and squeeze the bags and bottles, so that the internal sewage flows out. When the two movable plates 901 approach each other, the movable rod 14 is driven to move together through the connecting rod. When the first ratchet tooth 19 contacts the ratchet wheel 16, the ratchet wheel 16 is driven to rotate, so that the gear 31 rotates. The gear 31 meshes with the rack 17, so that the two partition plates 7 move away from each other along the guide rod 11 and compress the second spring 12. At this time, the garbage has been compressed to a certain extent and will not fall, while the sewage can quickly fall and is collected into the liquid collection box 4 through the drain pipe 3. At the same time, the push rod 23 disengages from the wedge block 29. Under the action of the fourth spring 27, the movable ring 24, the movable shaft 25, the movable block 26, the adsorbing member 28 and the wedge block 29 rise, so that the adsorbing member 28 and the magnetic member 22 are at the same height. After the two partition plates 7 move away from each other, the magnetic member 22 will contact the adsorbing member 28 to fix the position of the partition plate 7, and the sewage has sufficient time to be drained completely;

[0039] When the movable plates 901 approach, the magnetic strips 906 on both sides will be attached and adsorbed to temporarily fix the positions of the two porous plates 902. After the sewage is drained, the two movable plates 901 are driven to reset. The movable plates 901 will first drive the puncture needles 903 to pass through the holes in the porous plates 902 to scrape off the garbage attached to the puncture needles 903, and the puncture needles 903 can also be straightened. When the pulling force is greater than the suction force between the magnetic strips 906 on both sides, under the action of the first spring 904, the porous plates 902 are reset, and the garbage can automatically fall from between the two partition plates 7. When the movable plates 901 are completely reset, the push rod 23 presses the wedge block 29 to separate the adsorbing member 28 from the magnetic member 22. Under the action of the second spring 12, the partition plate 7 is also automatically reset. Subsequently, the garbage falls into the spiral feed pipe 2, and an external motor (not shown) drives the spiral shaft 6 to rotate to send the garbage into the cracking furnace for treatment.

[0040] One embodiment of the present invention has been described in detail above, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
