Description

Technical Field

[0001] This utility model belongs to the field of steel pipe manufacturing technology in the metallurgical industry, and specifically relates to a steel pipe blowing and suction ash collection device. Background Technology

[0002] In the production of hot-rolled steel pipes, a large amount of iron oxide scale is generated during high-temperature rolling and straightening deformation. This iron oxide scale causes the inner surface of the steel pipe to be rough and uneven, and also affects dimensional accuracy and subsequent processing results. Therefore, a cleaning process needs to be performed in the process. However, the usual methods and equipment make it difficult to collect iron oxide scale and other impurities, which not only causes serious air pollution, but also poses occupational health hazards due to the high intensity of manual iron oxide scale cleaning. The main reason is that the overall process design is unreasonable, and the methods for collecting and cleaning iron oxide scale are also unreasonable.

[0003] In view of the above factors, a steel pipe blowing and suction ash collection device is provided. This utility model can significantly reduce the rework rate caused by substandard cleaning of the inner surface of the steel pipe and reduce the downtime caused by cleaning of iron oxide scale.

[0012] The second processing device includes a negative pressure box and a collection box. A negative pressure pipe is welded onto the negative pressure box, and the end of the negative pressure pipe is connected to a negative pressure fan.

[0013] Furthermore, the negative pressure box and the collection box are an integral structure, and a gap is left between the negative pressure box and the collection box. A partition layer is fixedly installed inside the negative pressure box, and two sets of symmetrical sinking channels are fixedly installed at the bottom of the partition layer. The sinking channels are arranged opposite to the collection trough, and the collection trough is a funnel structure.

[0014] Furthermore, a vibrator is installed on the side wall of the collection tank. When the vibrator is powered on, it vibrates and causes the iron oxide scale on the inner wall of the collection tank to slide down to the ash outlet of the collection tank.
