[0028] The device is fixed to the kiln by the mounting plate 6, the baffle 1, the screw 2, the moving assembly and the cleaning assembly penetrate into the furnace, the telescopic push rod 5 is started, the telescopic push rod 5 pushes the push plate 4 to move deeper into the kiln, the push plate 4 pushes the turntable 3, the threads on the turntable 3 cooperate with the threads on the screw 2, so that the turntable 3 rotates around the screw 2 and moves deeper into the kiln, the turntable 3 drives the cleaning plate 16 and the nozzle to rotate around the axis of the screw 2 through the support rod 12, ensuring that the nozzle can clean any position of the inner wall of the furnace of the kiln, thereby achieving thorough cleaning of the furnace.

[0029] In some embodiments, mounting holes are provided on the mounting plate 6 and the kiln, and the device is fixed to the kiln by bolts.

[0030] In some embodiments, the displacement assembly also includes a baffle, which is arranged on the screw rod 2 and is slidably connected to the screw rod 2. The baffle is arranged between the turntable 3 and the baffle 1. A hydraulic cylinder is arranged at one end of the baffle 1 close to the baffle, and the hydraulic cylinder is in contact with the baffle at the end away from the baffle 1.

[0031] When the turntable 3 moves to the deepest part of the furnace, the telescopic push rod 5 is shortened, and the hydraulic cylinder is extended to push the baffle plate to slide along the screw rod 2. Under the action of the baffle plate, the threads on the turntable 3 cooperate with the screw rod 2, so that the turntable 3 rotates around the screw rod 2 and moves along the screw rod 2 toward the mounting plate 6 until the push plate 4 is against the mounting plate 6, and the turntable 3 is reset. During the reset process of the turntable 3, the nozzle cleans the inner wall of the furnace for the second time.

[0032] In some embodiments, the displacement assembly also includes a motor 7 and an electromagnet 10. The motor 7 is fixed on the mounting plate 6. A holding brake device is arranged inside the motor 7. The end of the screw rod 2 close to the mounting plate 6 passes through the mounting plate 6. The output shaft of the motor 7 is connected to the screw rod 2. The telescopic push rod 5 is fixedly connected to the push plate 4. An electromagnet 10 is arranged inside the push plate 4 and at the end of the turntable 3 close to the push plate 4.

[0033] When the turntable 3 moves to the deepest part of the furnace, the telescopic push rod 5 contracts, the motor 7 starts, the electromagnet 10 is energized, the push plate 4 and the turntable 3 are connected together under the action of the electromagnet 10, the motor 7 drives the screw rod 2 to rotate, and the thread on the turntable 3 cooperates with the screw rod 2. At this time, the telescopic push rod 5 limits the rotation of the turntable 3 through the push plate 4, so that the turntable 3 slides along the screw rod 2 until the turntable 3 is reset, the motor 7 is turned off, and the brake device is started to limit the rotation of the output shaft of the motor 7 to ensure the stationary state of the screw rod 2.

[0034] In some embodiments, the cleaning plate 16 is rotatably connected to the support rod 12 via a cleaning shaft 17 . A scraper 18 is also provided on the cleaning shaft 17 . The scraper 18 cooperates with the nozzle on the cleaning plate 16 .

[0035] In some embodiments, a groove body 11 is provided on the turntable 3, and the position of the groove body 11 corresponds to the position of the electromagnet 10 on the turntable 3. A slider 9 is slidably provided in the groove body 11, and a slide rod 8 is provided at the end of the slider 9 away from the electromagnet 10. The end of the slide rod 8 away from the slider 9 extends out of the groove body 11, and the end of the slide rod 8 away from the slider 9 is rotatably connected to a connecting piece, and the end of the connecting piece away from the slide rod 8 is rotatably connected to the cleaning shaft 17.

[0036] In some embodiments, an active ring 13 is provided at one end of the slide rod 8 away from the slide block 9 , a passive ring 15 is provided on the cleaning shaft 17 , and the connecting member is a connecting ring 14 , which is connected between the active ring 13 and the passive ring 15 .

[0037] In some embodiments, a torsion spring 19 is also included. The torsion spring 19 is rotatably connected to the support rod 12 . One end of the torsion spring 19 close to the cleaning shaft 17 is fixedly connected to the cleaning shaft 17 , and the other end of the torsion spring 19 is in contact with the support rod 12 .

[0038] When the turntable 3 moves to the deepest part of the furnace, the electromagnets 10 on the turntable 3 and the push plate 4 are energized. At this time, the turntable 3 and the push plate 4 are fixed together by the electromagnet 10. At the same time, the electromagnet 10 attracts the slider 9 to make the slider 9 move downward. The downward movement of the slider 9 drives the slide bar 8 to slide downward. The slide bar 8 pulls the connecting ring 14 through the active ring 13, thereby driving the passive ring 15 to move downward, and then the cleaning shaft 17 rotates to complete the position change of the nozzle and the scraper 18. At this time, the scraper 18 contacts the side wall of the furnace, the telescopic push rod 5 shrinks, the motor 7 starts and drives the screw rod 2 to rotate, and the screw rod 2 drives the turntable 3 to move. In the process of the turntable 3 moving toward the mounting plate 6, the scraper 18 on the turntable 3 cleans the fallen sediments in the furnace out of the furnace. After the turntable 3 returns to its initial position, the electromagnet 10 is powered off, and the cleaning shaft 17 returns to its initial position under the action of the torsion spring 19.

[0039] In some embodiments, the electromagnets 10 in the push plate 4 are arranged at intervals and correspond to the positions of the electromagnets 10 on the turntable 3. When the motor 7 starts to rotate, the turntable 3 rotates with the screw 2 until the positions of the electromagnets 10 on the turntable 3 coincide with the positions of the electromagnets 10 on the push plate 4. During the contraction of the telescopic push rod 5, the scraper 18 on the turntable 3 can clean up the debris and excess water at the bottom of the furnace.

[0040] The working principle of the furnace sediment cleaning device of the present invention is as follows: when it is necessary to clean the sediment in the furnace, the screw rod 2 is inserted into the furnace, the device is installed on the kiln through the mounting plate 6, the telescopic push rod 5 is extended, and the push plate 4 is pushed to move, and the push plate 4 pushes the turntable 3 to rotate around the screw rod 2 and move along the screw rod 2, and the nozzle on the turntable 3 cleans the inner wall of the furnace. When the turntable 3 enters the deepest part of the furnace, the electromagnet 10 on the turntable 3 and the push plate 4 is energized, the motor 7 is energized, and the brake device is closed. At this time, the motor 7 drives the screw rod 2 to rotate, and the turntable 3 rotates with the screw rod 2 until the electromagnet 10 on the turntable 3 and the push plate 4 coincide with each other, the turntable 3 is connected to the push plate 4, and the electromagnet 10 on the turntable 3 attracts the slider 9 to The cleaning shaft 17 is rotated by the sliding block 9 through the sliding bar 8, the active ring 13, the connecting ring 14 and the passive ring 15, so that the cleaning plate 16 and the scraper 18 are rotated 90° clockwise, the telescopic push rod 5 is contracted, and the turntable 3 and the push plate 4 move toward the mounting plate 6 under the action of the screw rod 2 and the telescopic push rod 5. The scraper 18 pushes the water and debris in the furnace toward the mounting plate 6 until it is pushed to the furnace outlet. After the push plate 4 and the turntable 3 are reset, the motor 7 stops rotating, the brake device is started to prevent the motor 7 from rotating, the electromagnets on the turntable 3 and the push plate 4 are powered off, and the cleaning shaft 17 is reset under the action of the torsion spring 19. At this time, the sliding bar 8 and the sliding block 9 are reset, and the deep cleaning of the furnace is completed.
