Description

Technical Field

[0001] The utility model belongs to the technical field of carbon production equipment, and in particular relates to a tunnel kiln secondary baking sagger repairing device. Background Art

[0002] Tunnel kiln secondary roasting is a relatively important link in the carbon industry production. Tunnel kiln secondary roasting is a process in which the impregnated product is placed in the chassis on the upper part of the tunnel kiln car, and a sagger is placed outside to isolate the product from oxidation, and then roasted according to a certain curve. Its characteristics are short time, high degree of automation, and convenient operation without medium protection, and it is widely used by carbon enterprises. However, there are problems. The sagger placed outside the product is deformed due to long-term high temperature roasting and overflow of internal volatiles. With long-term use, the degree of deformation increases. Due to the friction between the deformed part and the kiln body, it poses a great hidden danger to the longest operation of the tunnel kiln. At the same time, when the deformation is serious, the sagger and the kiln body are stuck, resulting in equipment and production accidents.

[0003] The original repair method of the sagger has caused serious carburization and embrittlement of the steel due to long-term use, and the deformed parts are treated by knocking and leveling, which is very easy to cause damage, resulting in the sagger being scrapped and unable to be used anymore. At the same time, the knocking and leveling method has high labor intensity for employees, slow progress in sagger repair and poor results. Utility Model Content

[0004] The utility model aims to provide a tunnel kiln secondary roasting sagger repairing device to solve the problems that the sagger is easily damaged during repair, resulting in the sagger being scrapped and unable to be used further, and the knocking and leveling method has high labor intensity.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tunnel kiln secondary roasting sagger repair device comprises a repair platform, fixed repair piles and a repair frame are arranged on the repair platform, a channel is arranged in the repair frame, a repair mechanism is arranged in the channel, the repair mechanism comprises a hydraulic station, a hydraulic cylinder and a repair top pile, the repair top pile is arranged at the end of the extended arm of the hydraulic cylinder, a pad is arranged at one end of the repair top pile close to the fixed repair pile, a slide rail is arranged on the bottom surface of the channel, and a pulley cooperating with the slide rail is arranged on the outer wall of the hydraulic cylinder.

[0007] In order to further realize the utility model, the repair frame and the fixed repair piles are perpendicular to the repair platform, the channel is perpendicular to the fixed repair piles, and the pad is parallel to the fixed repair piles.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model uses a hydraulic cylinder to drive the repairing top pile to take an indirect contact and gradual push repair method to the deformed part of the sagger, so as to repair the deformed part of the sagger. The utility model is simple, easy to make, and low in cost, which saves capital investment for the company.

[0010] The utility model is simple to manufacture and can repair the deformed part of the sagger, avoiding the knocking method adopted in the early stage, which not only improves the quality of the sagger repair, but also improves the progress of the sagger repair and reduces the labor intensity of employees. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The meanings of the accompanying numbers are as follows: 1. Repair platform; 2. Fixed repair pile; 3. Repair frame; 4. Channel; 5. Hydraulic station; 6. Hydraulic cylinder; 7. Repair top pile; 8. Extending arm; 9. Pad; 10. Slide rail; 11. Pulley; 12. Box to be repaired. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0014] like Figure 1 As shown, a tunnel kiln secondary roasting sagger repair device comprises a repair platform 1, on which fixed repair piles 2 and a repair frame 3 are arranged, the repair frame 3 and the fixed repair pile 2 are both perpendicular to the repair platform 1, a channel 4 is arranged in the repair frame 3, the channel 4 is perpendicular to the fixed repair pile 2, a repair mechanism is arranged in the channel 4, the repair mechanism comprises a hydraulic station 5, a hydraulic cylinder 6 and a repair top pile 7, the repair top pile 7 is arranged at the end of an extended arm 8 of the hydraulic cylinder 6, a pad 9 is arranged at one end of the repair top pile 7 close to the fixed repair pile 2, the pad 9 is parallel to the fixed repair pile 2, a slide rail 10 is arranged on the bottom surface of the channel 4, and a pulley 11 cooperating with the slide rail 10 is arranged on the outer wall of the hydraulic cylinder 6.

[0015] During the repair operation, the sagger 12 to be repaired is first lifted to the fixed repair pile 2 by a bridge crane and the bottom end of the sagger is inserted therein, and the hydraulic station 5 is controlled by the electrical control system to push the hydraulic cylinder 6 to move. The hydraulic cylinder 6 slides horizontally forward and backward along the slide rail 10 through the pulley 11, and the repair of different deformed parts of the sagger 12 to be repaired is achieved by the horizontal movement of the repair top pile 7. After the part to be repaired is determined, the pad 9 is placed between the part to be repaired of the sagger 12 to be repaired and the repair top pile 7. The purpose is to increase the contact area and reduce pressure concentration. At the same time, a repair can also be carried out on a larger area. The deformed part of the sagger 12 to be repaired is repaired by an indirect contact, gradual and stepwise pushing repair method is adopted through the repair top pile 7, so as to repair the deformed part of the sagger.
