Description

Technical Field

[0001] The utility model relates to the technical field of welding repair machines, in particular to a lightweight coke oven ceramic welding repair machine. Background Art

[0002] In the coking industry, as the core production equipment, the silica bricks inside the coke oven carbonization chamber will inevitably be damaged such as worn, eroded, and fractured during long-term operation. In order to ensure the stable operation of the coke oven and extend its service life, it is particularly important to repair the damaged silica bricks in a timely manner. As an important tool for repairing these components, the mobility of the coke oven ceramic welding repair machine directly affects the repair efficiency. However, traditional welding repair machines often have problems such as heavy weight and inconvenient movement, bringing many inconveniences to on-site operations.

[0003] Most of the coke oven ceramic welding repair machines on the market currently adopt relatively traditional structural designs. Although they can meet the basic welding repair requirements, there are obvious deficiencies in terms of equipment weight and mobility. The heavy fuselage not only increases the difficulty of transportation, installation, and use, but also limits the flexible operation of the welding repair machine in a narrow space. In addition, the anti-blocking device design of traditional welding repair machines is often relatively complex, increasing the overall weight of the equipment and further exacerbating the problem of inconvenient movement.

[0004] For example, a high-temperature furnace kiln welding repair machine disclosed in a Chinese patent (Publication No.: CN202098851U) consists of a hopper, a speed-regulating motor, a star-shaped feeder, an oxygen group, a four-way Venturi mixer, and a variable-diameter welding torch. The hopper is connected to the star-shaped feeder below. The star wheel in the star-shaped feeder is directly connected to the speed-regulating motor shaft, and it rotates bidirectionally for feeding, making the feeding more uniform. It is not affected by forward or reverse rotation and has a larger range of adjustment of the feeding amount. The repair material is put into the hopper. Under the action of gravity and the negative pressure adsorption generated by the oxygen flow in the four-way Venturi mixer, the repair material is evenly fed into the four-way Venturi mixer through the transmission of the star wheel in the star-shaped feeder. The oxygen flow evenly blows the repair material towards the welding torch and blows it to the furnace wall through the variable-diameter welding torch to achieve the welding repair effect. In order to avoid blockage of the repair material at the feeding outlet, powder is fed through the star-shaped feeder. However, although this can reduce the blockage phenomenon to a certain extent, it increases the overall weight of the equipment and causes difficulties in transfer. Summary of the Utility Model

[0005] In order to solve the above problems, the embodiment of the utility model provides a coke oven ceramic welding repair machine that will not have a material jamming phenomenon and is convenient to move.

[0006] In order to achieve the above object, the embodiment of the present utility model specifically adopts the following technical solutions: A coke oven ceramic welding repair machine includes a housing. An inlet section is provided at the upper part of the housing, and a welding section is provided at the lower part. The inlet section includes a blanking hopper, and an anti-blocking module is provided in the middle of the blanking hopper. The welding section includes a conveying pipeline connected to the discharge end of the blanking hopper, and an oxygen pipeline is provided at the end of the conveying pipeline.

[0007] As a further improvement of the above technical solution:

[0008] The blanking hopper includes a receiving part and a discharging part, and a placement chamber for installing the anti-blocking module is provided between the receiving part and the discharging part.

[0009] The anti-blocking module includes a transmission rod arranged in the placement chamber. A spiral conveyor plate is arranged on the transmission rod, and a driving source connected to the transmission rod is arranged outside the placement chamber.

[0010] Sealing baffles are arranged at both ends of the transmission rod. Bearing seats for installing the transmission rod are arranged on the sealing baffles, and a limiting boss for placing the sealing baffle is arranged at the upper end of the discharging part.

[0011] The number of the spiral conveyor plates is two and they are symmetrically distributed with respect to the midline of the blanking hopper.

[0012] An oxygen distribution hose is arranged on the oxygen pipeline, and an intake valve is arranged at the connection between the oxygen distribution hose and the oxygen pipeline.
