[0026] Embodiment 1

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an automatic cleaning device for pulverized coal gasification slag inlet includes a furnace body 1 and a sleeve 2. The sleeve 2 is fixedly inserted through the bottom of the furnace body 1. A rotating rod 3 is rotated through the middle of the inner side of the sleeve 2. Connecting rods 4 are rotated through the upper left and right sides of the rotating rod 3. A scraper 5 is rotatably sleeved on the outside of the connecting rod 4. The outer wall of the scraper 5 is in contact with the inner wall of the sleeve 2. A number of first cutting blades 6 are fixed on the inner side of the scraper 5. The first cutting blades 6 are perpendicular to the scraper 5. A drive assembly 7 is provided on the outer wall of the sleeve 2. The drive assembly 7 includes a motor 701 fixedly installed on the left side of the bottom of the sleeve 2. A drive gear 702 is fixedly sleeved on the outside of the output end of the motor 701. A driven gear 703 is fixedly sleeved on the lower outside of the rotating rod 3. The driven gear 703 and the drive gear 702 are designed to mesh.

[0028] The sleeve 2 has guide grooves 8 integrally formed at both the upper and lower ends inside. The guide grooves 8 have a circular cross-section when viewed from above. A slider 9 is slidably connected inside the guide grooves 8. The slider 9 is fixedly connected to the scraper 5. The front and rear ends of the slider 9 are fixedly provided with second cutting blades 10. When the operator turns on the motor 701, the motor 701 controls the drive gear 702 to drive the driven gear 703, along with the rotating rod 3, connecting rod 4, and scraper 5 to rotate. This causes the scraper 5 to move the slider 9 along the direction of the guide grooves 8. At this time, the scraper 5 scrapes off the residue adhering to the inner wall of the sleeve 2, and the slider 9 drives the second cutting blades 10 to cut off the residue inside the guide grooves 8, ensuring the smooth movement of the slider 9 along the direction of the guide grooves 8. At the same time, the scraper 5 drives the first cutting blades 6 to crush the scraped blocky residue.

[0029] Example 2

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a push plate 11 is fixedly installed at the lower inner end of the scraper 5. The push plate 11 is perpendicular to the scraper 5, and the bottom surface of the push plate 11 is in contact with the inner bottom surface of the sleeve 2. A discharge pipe 12 is fixedly installed through the rear end of the bottom of the sleeve 2. The top surface of the discharge pipe 12 is flush with the inner bottom surface of the sleeve 2. An installation rod 13 is rotated inside the rotating rod 3. The axis of the rotating rod 3 is coaxial with the axis of the installation rod 13. An active bevel tooth 14 is fixedly installed at the top of the installation rod 13. A driven bevel tooth 15 is fixedly installed inside the connecting rod 4. The driven bevel tooth 15 and the active bevel tooth 14 are in gear meshing. The driven bevel teeth 15 of the two parts are designed to be mirror-distributed with the axis of the mounting rod 13 as the center. Several third cutting blades 16 are fixed on the outer wall of the connecting rod 4. The third cutting blades 16 are offset from the first cutting blades 6. Pulleys 17 are fixedly sleeved on the outside of the output end of the motor 701 and the outside of the mounting rod 13. A toothed belt 18 is provided on the outside of the pulley 17 by a tight fit. The pulleys 17 of the two parts are the same size. The axis of the output end of the motor 701 is parallel to the axis of the mounting rod 13.

[0031] According to the operation mode in embodiment 1, when the connecting rod 4 drives the scraper 5 to rotate, the scraper 5 together with the push plate 11 discharges the granular residue in the sleeve 2 from the discharge pipe 12 to the outside. In addition, when the motor 701 is turned on, the motor 701 controls the belt pulley 17 to drive the gear belt 18 to rotate the mounting rod 13 and the driving bevel gear 14, and the driving bevel gear 14 controls the driven bevel gear 15 to rotate together with the connecting rod 4 and the third cutting edge 16. At this time, the third cutting edge 16 and the first cutting edge 6 are in synchronous and non-identical rotation processing. Through the above mode, the crushing effect of the blocky residue is improved, and the effect of discharging the crushed residue from the discharge pipe 12 to the outside is further improved.
