Description

Water curtain purging device on grinding machine
Technical Field
The invention relates to the field of finishing and grinding processing of steel plates in the metallurgical industry, in particular to a water curtain purging device on a grinding mill.
Background
The thick plate product has very strict standards and requirements on the surface quality, so that the common defects of the steel plate surface, such as foreign matter press-in, scratch, indentation, roll mark, edge linear defect and the like, generally need to be repaired and repaired to eliminate the defects. If the defect is locally small, the defect is ground by a grinder manually; however, if the defects are distributed on the steel plate in a large area in a full-length manner, the manual grinding workload is huge and the efficiency is low, so that a grinding machine is required to perform mechanical high-efficiency grinding operation.
The structure of the existing grinding machine is shown in figure 1, a sand belt for grinding a steel plate 3 is arranged on a liftable grinding head 4, a transverse trolley 2 drives the liftable grinding head 4 to be used for positioning in the width direction of the steel plate 3, and a rack trolley 1 drives the transverse trolley 2 to move back and forth along the length direction of the steel plate 3, so that mechanical grinding operation is realized.
According to the defect depth, the width of a defect strip and the like, an operator can automatically finish multi-pass back-and-forth reciprocating polishing through the grinding machine after parameter setting, and the efficiency is obviously improved. However, the existing grinding mill has two problems to be solved in practical use:
1. a large amount of metal granular dust is generated in the grinding process, and a low-pressure point spray water pipe is designed by a grinding head position manufacturer of the grinding machine, so that the aim of cooling and grinding a belt by using spray water is to prolong the service life of the belt. The use of local low-pressure spray water enables a part of metal particle dust to be attached to the surface of the steel plate through water precipitation, and precipitates are difficult to clean after being dried in the air, so that the surface quality of the steel plate is directly influenced, and therefore, the subsequent special manual cleaning is needed, and the operation is very complicated; the other part of the dust is scattered into the air to pollute the environment.
2. The grinding machine generates a large amount of heat when a belt rotating at high speed and the surface of a steel plate are ground in the grinding operation, so that local micro deformation of a grinding part is easily caused due to uneven heating of the steel plate in the process of grinding a thin plate, and the shape control is not facilitated. Although there is spray water as described above, the low pressure point spray water is primarily used to reduce the belt temperature and has no significant effect on the plate shape control.
Patent application No. 201720216029.2 discloses a "rolling mill and its strip steel purging device", which includes a water supply pipeline, a valve is arranged on the water supply pipeline; and the inlet end of the purging pipeline is communicated with the water outlet end of the water supply pipeline, and the water flowing out of the outlet end of the purging pipeline can blow away the iron scraps on the upper surface of the strip steel. Therefore, scrap iron falling on the upper surface of the strip steel is prevented from entering the rolling mill along with the strip steel, and the condition of influencing the quality of strip steel products is avoided. The device has the blowing effect on a small amount of scrap iron generated by scraping the edge of the strip steel and the guide plate at the inlet side of the finishing mill, but has the defect that if the scrap iron or foreign matters are more, the blowing pipeline arranged in a linear mode is not beneficial to timely removing the scrap iron or the foreign matters from the upper surface of the steel plate, and the accumulation phenomenon is easily generated at the front section of a blowing point. In addition, the device is only suitable for one-way purging, and has great limitation in use.
