It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: an automatic furnace lining ejection and cleaning device, including a furnace body 1, a furnace lining 7 installed in the inner cavity of the furnace body 1, a support frame 5 slidably connected to the top of the furnace body 1, a turntable 4 rotatably connected to the surface of the support frame 5, a hydraulic push rod 8 installed at one end of the turntable 4, a fixing ring 10 fixedly connected to one end of the hydraulic push rod 8, guide plates 14 provided on both sides of the surface of the fixing ring 10, a connecting plate 12 slidably connected to the surface of the guide plate 14, a movable plate 13 hinged to the surface of the connecting plate 12, a scraper 9 fixedly connected to one end of the connecting plate 12, and the scraper 9 adhering to the inner wall of the furnace lining 7;

[0024] The rotation of the hydraulic push rod 8 and scraper 9 driven by the turntable 4 enables the scraper 9 to clean different areas of the inner wall of the furnace lining 7. Through the cooperation of the movable plate 13, connecting plate 12, rubber sleeve 16 and guide plate 14, the scraper 9 fits against the inner wall after entering the bottom of the furnace lining 7. The hydraulic push rod 8 drives the scraper 9 to reciprocate, which not only achieves comprehensive cleaning of the inner wall of the furnace lining 7, but also pushes out the scraped debris, improving cleaning efficiency.

[0025] Example 2

[0026] Please see Figures 1 to 4Based on Embodiment 1, in order to enable the hydraulic push rod 8 to drive the scraper 9 to rotate, square grooves are opened on both sides of the surface of the furnace body 1, the support frame 5 is slidably connected to the surface of the square grooves, and a rotating hole is opened on the surface of the furnace body 1. The turntable 4 is rotatably connected in the rotating hole, and four round holes are arrayed around the rotating hole. Two bolts 6 pass through the surface of the turntable 4 and the round holes. By setting the round holes and bolts 6, the turntable 4 is fixed at different angles. This allows the hydraulic push rod 8 and the scraper 9 connected to it to clean the inner wall of the furnace lining 7 from different directions during cleaning operations, which greatly improves the cleaning coverage and avoids cleaning dead corners.

[0027] A hydraulic pump 3 is fixedly connected to the surface of the turntable 4. The hydraulic pump 3 is fixedly connected to one end of the hydraulic push rod 8. A positive magnetic sheet 19 is fixedly connected to the surface of the end of the hydraulic push rod 8 away from the hydraulic pump 3. A slot is opened on the surface of the fixing ring 10. The upper end of the slot and the guide groove 15 is used to accommodate two movable plates 13. Fixing plates 11 are fixedly connected to both sides of the surface of the fixing ring 10. The fixing plates 11 have a square plate structure. A guide groove 15 is opened on the surface of the fixing plates 11. The guide groove 15 is a "T" shaped groove and communicates with the slot.

[0028] Example 3

[0029] Please see Figures 1 to 5 Based on Embodiment 2, in order to achieve the adhesion between the scraper 9 and the surface of the furnace lining 7, the guide plate 14 is fixedly connected to the surface of the guide groove 15, and a rubber sleeve 16 is sleeved on the surface of the guide plate 14. One end of the rubber sleeve 16 is fixedly connected to the surface of the guide groove 15, and the other end of the rubber sleeve 16 is fixedly connected to the surface of the connecting plate 12. The rubber sleeve 16 is in a stretched state, and the rubber sleeve 16 has a pulling effect on the connecting plate 12. When the rubber sleeve 16 is in the original state, there is a certain angle between the two movable plates 13, and the scrapers 9 on both sides are no longer in contact with the inner wall of the furnace lining 7. When the rubber sleeve 16 is in a stretched state, the scrapers 9 on both sides are in contact with the inner wall of the furnace lining 7.

[0030] The connecting plate 12 has a square cylindrical structure. Two U-shaped blocks 2 are fixedly connected to the surface of the connecting plate 12. A first pin 17 is rotatably connected to the surface of the U-shaped blocks 2. The two first pins 17 are fixedly connected to the two sides of the movable plate 13. A negative magnetic sheet 20 is fixedly connected to the surface of the movable plate 13 near the fixed ring 10. The positive magnetic sheet 19 and the negative magnetic sheet 20 attract and adhere to each other. A second pin 18 is fixedly connected to the surface of one movable plate 13. The second pin 18 is rotatably connected to the surface of the other movable plate 13.

[0031] In actual use, first rotate the furnace body 1 ninety degrees around the bottom plate to make it parallel to the horizontal plane. Slide the support frame 5 into the square groove on the surface of the furnace body 1 for positioning. Pull the two movable plates 13 outward by hand. At this time, the positive magnetic sheet 19 and the negative magnetic sheet 20 move away from each other, and the rubber sleeve 16 returns to its original state from the stretched state, driving the two movable plates 13 to move towards one end of the fixed ring 10. The two movable plates 13 rotate around the first pin 17 as the center, so that the two movable plates 13 form a certain angle. The two movable plates 13 drive the connecting plate 12 to move closer to each other. The connecting plate 12 drives the scraper 9 to move. Then loosen the bolt 6, rotate the turntable 4, and rotate the two scrapers 9 to be parallel to the horizontal plane. Then, insert the bolt 6 through the round holes on the surface of the turntable 4 and the support frame 5 respectively to limit their position.

[0032] Hydraulic pump 3 drives hydraulic push rod 8 to extend into furnace lining 7. When the two movable plates 13 reach the bottom of furnace lining 7, the bottom of furnace lining 7 squeezes the movable plates 13. The movable plates 13 drive the connecting plates 12 to move along the surface of guide plate 14 until the two movable plates 13 are embedded in the surface of slot and guide groove 15. Positive magnetic sheet 19 and negative magnetic sheet 20 attract each other and limit the movable plates 13. At this time, the scrapers 9 at both ends are in contact with the surface of furnace lining 7. Hydraulic pump 3 drives hydraulic push rod 8 to retract. Scraper 9 scrapes and cleans the debris inside furnace lining 7. The impurities on both sides will gather on the bottom side of the inner wall of furnace lining 7 under the action of gravity. Then drive scraper 9 to move to the deepest part of furnace lining 7, loosen bolt 6, rotate turntable 4 to ninety degrees, so that scraper 9 on both sides is perpendicular to the horizontal plane. Then drive hydraulic push rod 8 to retract. Scraper 9 on both sides cleans the impurities on the inner wall of furnace lining 7 and pushes out the impurities gathered on the bottom side.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
