[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] Please refer to the following: Figures 1 to 8 The present application provides a waste ash discharge device. The waste ash discharge device includes a support frame 1, a screw feeding mechanism 2, and a connecting pipe 3. The screw feeding mechanism 2 is connected to the top of the support frame 1. The screw feeding mechanism 2 has an inlet and an outlet 21. The top of the connecting pipe 3 communicates with the outlet 21 of the waste ash silo and is fixed to the waste ash silo. A flexible hose 4 is fixedly connected to the bottom of the connecting pipe 3, and the flexible hose 4 communicates with the inlet of the screw feeding mechanism 2. The inlet of the screw feeding mechanism 2 is fixedly provided with a feed hopper 22, and a cloth bag 5 is connected to the inner wall of the feed hopper 22. A connecting ring 51 is fixed on the cloth bag 5, and the flexible hose 4 is connected to the connecting ring 51.

[0020] This application provides a waste ash discharge device. Compared with the prior art, when discharging dust from the waste ash bin, the valve of the waste ash bin is opened, and under the vibration of the pneumatic hammer on the waste ash bin, the dust in the waste ash bin can fall into the inlet of the screw feeding mechanism 2 through the connecting pipe 3. Through the conveying action of the screw feeding mechanism 2, the dust can be discharged from the outlet 21. A ton bag is set at the outlet 21 of the screw feeding mechanism 2 to collect the dust discharged from the outlet 21 of the screw feeding mechanism 2. Through the above-mentioned arrangement of this application, the dust in the waste ash bin is guided into the screw feeding mechanism 2, and the dust is sent to the ton bag by the screw feeding mechanism 2. This can reduce the situation where dust scatters and falls from the outlet 21 of the waste ash bin, and can reduce the situation where operators are covered in dust.

[0021] It should be noted that the screw feeding mechanism 2 includes a sleeve 23, a screw blade rotatably disposed inside the sleeve 23, and a drive motor 24 disposed at one end of the sleeve 23. The sleeve 23 and the drive motor 24 are both fixed on the support frame 1. A rotating shaft is provided inside the sleeve 23, and the screw blade is fixed on the outer peripheral wall of the rotating shaft. One end of the rotating shaft extends out of the sleeve 23, and the extended end of the rotating shaft is connected to the output shaft of the drive motor 24.

[0022] By driving the rotating shaft with the drive motor 24, the spiral blades can be conveyed to transport the dust, and the dust can finally fall into the ton bag from the discharge port 21. By controlling the rotation speed of the spiral blades, the waste ash can be evenly discharged into the ton bag. Compared with the method of directly discharging from the waste ash silo, the discharge method of this application can reduce the amount of dust scattered. In the prior art, the method of directly discharging ash from the waste ash silo is uncontrollable in the ash falling process, while the discharge process in this application is controllable.

[0023] By installing a flexible hose 4 at the bottom of the connecting pipe 3, the flexible hose 4 can alleviate the shaking when the screw feeding mechanism 2 vibrates, thereby reducing the shaking of the connecting pipe 3.

[0024] By setting a cloth bag 5 inside the feed hopper 22 and connecting the cloth bag 5 to the hose 4 via a connecting ring 51, the connecting pipe 3 can communicate with the inside of the cloth bag 5, and the inside of the cloth bag 5 can communicate with the feed hopper 22. Therefore, during the material feeding process, the dust in the connecting pipe 3 can fall into the feed hopper 22. By setting the cloth bag 5 in the feed hopper 22, the air pressure at the position of the feed hopper 22 can be balanced, ensuring that the dust in the connecting pipe 3 can fall into the feed hopper 22 and can be trapped inside the cloth bag 5.

[0025] In some embodiments, such as Figures 1 to 8 As shown, the connecting ring 51 has several connecting holes along its circumference, and a flange is connected to the hose 4. The through holes on the flange are aligned with the through holes on the connecting ring 51. The flange and the connecting ring 51 are fixed by bolts and nuts.

[0026] A sealing gasket is provided between the flange and the connecting ring 51. The through hole on the flange and the connecting hole on the connecting ring 51 are both located outside the sealing gasket. After the connecting ring 51 and the flange are fixed with bolts and nuts, the seal between the hose 4 and the bag 5 can be guaranteed. The hose 4 is connected to the connecting ring 51 through the flange. When it is necessary to clean the dust on the inner wall of the hose 4, simply remove the flange from the connecting ring 51 and then clean the dust on the inner wall of the hose 4 with a cleaning tool. During the cleaning process, the hose 4 is swung at a certain angle to facilitate the operator to clean the inner wall of the hose 4 with a cleaning tool. A collection tray is placed in the dust collection area to collect the dust that falls from the hose 4.

[0027] In some embodiments, such as Figures 1 to 8 As shown, the connecting pipe 3 is connected to the outlet 21 of the waste ash bin by a flange. The interior of the connecting pipe 3 has a scraping structure 6, and the middle of the scraping structure 6 has a through hole for dust to pass through. When the connecting pipe 3 is working normally, the scraping structure 6 is located at the bottom of the connecting pipe 3.

[0028] With the above settings, after the connecting pipe 3 has been used for a certain period of time, the connecting pipe 3 can be removed from the ash bin and the dust on the inner wall of the connecting pipe 3 can be cleaned. When the connecting pipe 3 is in normal use, the scraping structure 6 is located at the bottom of the connecting pipe 3 and has a through hole for dust passage. Therefore, the scraping structure 6 will not affect the normal dust falling process of the connecting pipe 3.

[0029] In some embodiments, such as Figures 1 to 8As shown, the scraping structure 6 includes a scraping ring 61 and a supporting ring 62; the scraping ring 61 is disposed inside the connecting pipe 3; the outer peripheral wall of the scraping ring 61 contacts the inner peripheral wall of the connecting pipe 3, and the scraping ring 61 can slide inside the connecting pipe 3; the supporting ring 62 is fixed at the bottom end of the connecting pipe 3; when the connecting pipe 3 is working normally, the supporting ring 62 supports the scraping ring 61; wherein, after the top end of the connecting pipe 3 is removed, the top end of the connecting pipe 3 is set downwards, and the scraping structure 6 can slide out from the top of the connecting pipe 3 to scrape off the dust on the inner peripheral wall of the connecting pipe 3.

[0030] During normal operation of the connecting pipe 3, the support ring 62 can support the scraper ring 61. The diameter of the through hole on the support ring 62 is not less than the diameter of the through hole on the scraper ring 61, so as to avoid material accumulation on the support ring 62.

[0031] When it is necessary to clean the dust on the inner wall of the connecting pipe 3, the top of the connecting pipe 3 is removed from the ash bin, and then the top of the connecting pipe 3 is placed downwards, so that the height of the top of the connecting pipe 3 is lower than the height of the bottom of the connecting pipe 3. The scraper ring 61 inside the connecting pipe 3 slides under its own weight to scrape off the dust on the inner wall of the connecting pipe 3. With the cooperation of the hose 4 and the cloth bag 5, the top of the connecting pipe 3 can be placed downwards.

[0032] When disassembling the connecting pipe 3, a disassembly platform is set up on the surrounding ground with steps to facilitate operators to climb onto the platform and disassemble the top of the connecting pipe 3, removing it from the waste ash bin. The waste ash bin outlet 21 has a valve, which is closed during the disassembly of the connecting pipe 3. After disassembly, the connecting pipe 3 is slowly lowered by two operators working together, until the top of the connecting pipe 3 is lower than the bottom. During the process of the scraper ring 61 sliding along the inner circumferential wall of the connecting pipe 3, the operators support the connecting pipe 3 at all times.

[0033] In some embodiments, such as Figures 1 to 8 As shown, the top of the scraper ring 61 is a conical surface. During the normal dust discharge process of the connecting pipe 3, the dust can move along the conical surface, thereby reducing the amount of dust accumulating on the top of the scraper ring 61.

[0034] In some embodiments, such as Figures 1 to 8As shown, a collection bag (not shown) is provided near the top of the connecting pipe 3. After the top of the connecting pipe 3 is separated from the ash bin, the collection bag can be fitted onto the top of the connecting pipe 3 to collect the dust scraped by the scraper ring 61. An annular groove 31 is provided on the outer peripheral wall of the connecting pipe 3 near the top, and a clamp (not shown) is provided inside the annular groove 31. When the collection bag is fitted onto the top of the connecting pipe 3, the annular groove 31 is located inside the collection bag, and the clamp is located outside the collection bag, with the clamp tightening the collection bag. During normal use of the connecting pipe 3, the collection bag can be tied to the outer peripheral wall of the connecting pipe 3 with a rope.

[0035] After removing the top end of the connecting pipe 3, the collection bag is placed over the top end of the connecting pipe 3 and tightened with a clamp to fix the collection bag to the top end of the connecting pipe 3. After tilting the top end of the connecting pipe 3, the scraper ring 61 removes the dust from the inner circumference of the connecting pipe 3, and the falling dust can enter the collection bag.

[0036] After the top of the connecting pipe 3 tilts downward, the scraper ring 61 can scrape the dust on the inner wall of the connecting pipe 3 under its own gravity, and the scraped dust can fall into the collection bag.

[0037] If dust adheres to the inner wall of the connecting pipe 3, the scraper ring 61 cannot remove it by its own weight, meaning the scraper ring 61 cannot slide inside the connecting pipe 3. A threaded hole can be pre-set on the scraper ring 61, and then a rod with an external thread at one end can be threaded into the scraper ring 61. The operator can then pull the rod to move the scraper ring 61 and scrape away the dust from the inner wall of the connecting pipe 3. When the scraper ring 61 is driven by the rod, there is no need to cover the connecting pipe 3 with a collection bag. Even if dust is present in the threaded hole of the scraper ring 61, it will not affect the threaded engagement between the rod and the scraper ring 61.

[0038] After scraping is complete, remove the rod from the scraper ring 61; during the dust scraping process, the top end of the connecting pipe 3 is set downwards.

[0039] In some embodiments, such as Figures 1 to 8 As shown, a threaded hole is provided on the outer peripheral wall of the top end of the connecting pipe 3, and a positioning bolt 32 is provided at the position of the threaded hole in the connecting pipe 3; the threaded section of the positioning bolt 32 is located inside the connecting pipe 3; wherein, the positioning bolt 32 can contact the scraper ring 61 to limit the scraper ring 61.

[0040] The above settings limit the sliding position of the scraper ring 61, preventing it from sliding out of the connecting pipe 3. The positioning bolt 32 is threaded into the connecting pipe 3, making it easy to install and remove. When the scraper ring 61 needs to be replaced, the positioning bolt 32 can be removed to allow the scraper ring 61 to slide out of the connecting pipe 3. After inserting a new scraper ring 61 into the connecting pipe 3, the positioning bolt 32 can be screwed back onto the connecting pipe 3.

[0041] In some embodiments, such as Figures 1 to 8 As shown, the scraping structure 6 includes a scraping ring 61 and a connecting rod 63; the scraping ring 61 is located inside the connecting pipe 3; the outer peripheral wall of the scraping ring 61 contacts the inner peripheral wall of the connecting pipe 3; the bottom end of the connecting rod 63 is connected to the scraping ring 61; the top end of the connecting rod 63 has a hook 64, the top of the connecting pipe 3 has a relief groove 33 for placing the hook 64, and the bottom of the relief groove 33 has an insertion hole 34 for inserting and engaging with the hook 64; wherein, after the connecting pipe 3 is separated from the waste ash bin, the connecting rod 63 can drive the scraping ring 61 to slide inside the connecting pipe 3; the top of the scraping ring 61 is a conical surface.

[0042] With the above setup, after the top of the connecting pipe 3 is removed from the ash bin, the connecting pipe 3 can be tilted at a certain angle without the top of the connecting pipe 3 being lower than the bottom. The operator can then operate the connecting rod 63 to drive the scraper ring 61 to move and clean the dust on the inner circumference of the connecting pipe 3. The operator drives the scraper ring 61 to slide on the inner circumference of the connecting pipe 3 through the connecting rod 63, and the scraped dust falls down the connecting pipe 3 into the feed hopper 22. By setting a conical surface at the top of the scraper ring 61, it is easy for the scraped dust to fall downward from the conical surface.

[0043] It should be noted that the dust being scraped off is the dust adhering to the inner circumferential wall of the connecting pipe 3. After the adhering dust is scraped off, the scraped dust can fall downwards.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
