Description

Float glass roller way online cleaning device

Technical Field

The utility model relates to an online cleaning device for a float glass roller way.

Background

In the float glass production process, the batch is fed into a melting furnace through a batch feeder, melted into glass liquid at a high temperature of 1550-1600 ℃, cooled to about 1100 ℃ through the processes of clarification, cooling and the like, then freely flowed downwards into a tin bath, floated on molten metal tin liquid, flattened, polished and molded to form the glass plate with the expected thickness and width. The formed glass plate is slowly cooled, the temperature is reduced to about 600 ℃ when reaching the outlet of the tin bath, then the glass plate is lifted and conveyed by three transition rollers with gradually increased horizontal height, and enters an annealing kiln for annealing and cooling, and when the temperature of the glass plate is gradually reduced to be close to the room temperature, cutting, stacking, packaging and warehousing are carried out.

At present, the float glass production is generally carried out for about 10 years in a kiln period, and during the 10 years, continuous flow production for 24 hours per day is required to be carried out on a conveying roller way, and due to the high temperature of a glass belt and close to softening, particles adhered on the conveying roller way can cause flaws on the surface of the glass, which are difficult to repair. As the production proceeds, tin dust on the lower surface of the glass will adhere to the conveyor roll surface with the glass ribbon, and these contaminants adhering to the roll surface will occasionally contaminate the lower surface of the glass, thereby causing quality defects under the glass sheet. Therefore, the tin stripping roller way needs to be cleaned regularly, and the currently adopted technologies are as follows:

the first is to use a tin cleaning device, namely, a tensioning device is arranged right below a transition roller in a slag box at the outlet end of a tin bath, and graphite blocks are placed on the tensioning device. When the transition roller is required to be wiped, the graphite blocks are raised to be in contact with the roller surface of the transition roller by the action of external force, and pollutants on the surface of the transition roller are wiped and removed. However, the wiping effect is unstable along with abrasion or pulverization and erosion of the graphite blocks, and the control is difficult in the use process. And the tin wiping device placing groove is easy to deform at normal production high temperature, so that the tin wiping tensioning device is lifted and blocked, even blocked, and cannot be replaced.

And the second is roll change cleaning, namely the conveying roller way is required to be detached, the slag box or the annealing kiln is removed, and the conveying roller way is replaced or cleaned and then is reloaded in place. The mode needs more than 4 hours of cooperation work of 6-8 people, and the width of the glass plate in the tin bath needs to be greatly narrowed in the roll changing process, so that the process system of the tin bath is seriously influenced, the production quality is greatly influenced, and the safety risk of broken plates exists.

And thirdly, cleaning the transition roller by adjusting the friction force between the glass plate and the roller way. Technological parameters such as glass ribbon temperature, roller height, roller speed and the like need to be adjusted in the cleaning process, the control precision requirement is high, otherwise, stretching is easy to form, the risk of broken plates exists, and the adjustment of the technological parameters is more, so that the influence on the tin bath process control is extremely large. In addition, a matched independent roller speed adjusting device is required to be installed, so that the input cost and the maintenance cost are increased.
