Rolled glass roller way heating and cleaning device and cleaning method of rolled glass roller way

Abstract

The invention discloses a rolled glass roller way heating and cleaning device which comprises a trolley, a heating water tank, a booster pump, an upper roller cleaning water gun and a lower roller cleaning water pipe, the heating water tank and the booster pump are installed on the trolley, a water supply pipe is connected with the upper portion of the heating water tank through a floating ball valve, and an electric heating rod and a temperature sensor are arranged on the lower portion in the heating water tank. The water inlet end of the booster pump is connected with the heating water tank, the upper roller cleaning water gun and the lower roller cleaning water pipe are selectively connected with the water outlet end of the booster pump through a high-temperature-resistant and high-pressure-resistant water pipe, the lower roller cleaning water pipe comprises a section of stainless steel water pipe, and a row of water outlet holes are formed in the side wall of the stainless steel water pipe. And the length of the row of water outlet holes is matched with the length of the roller surface of the calendaring lower roller way. The heating water tank is adopted, cleaning is easier through hot water cleaning, and meanwhile irreversible damage caused by cracks of the roller way due to the fact that the temperature difference is too large when the roller way is cleaned with cold water in the high-position state is prevented. The invention further provides a cleaning method of the rolled glass roller way.

Description

technical field [0001] The invention relates to a heating and cleaning device for a rolling glass roller table and a cleaning method for a rolling glass roller table. Background technique [0002] At present, the production capacity of photovoltaic glass is expanding rapidly, and the single-line pulling amount of the melting furnace is gradually increasing, the competition is intensifying, and the requirements for the quality of the board surface are higher. In order to avoid improper operation, it is the key to improve the yield of glass. During the production process of the calendering method, the upper and lower rollers are calendered, and under high temperature conditions, it is easy to oxidize sticky debris and mirabilite particles, resulting in roller damage on the upper surface of the glass, The lower surface is prone to gray spots (under normal circumstances, the lower roller is cleaned once a week, and the upper roller is cleaned once every 10 days). At this time, i...

AI Technical Summary

Problems solved by technology

The current method of cleaning roller table equipment with cold water and air compressed air can make the water out of the water gun atomized and rinse the roller table. There are mottled spots; 2. Washing with cold water reduces the temperature of the roller table and takes a long time to recover the temperature (the normal temperature of the roller table is about 320°C-400°C during production), and the time for glass scrapping is relatively long, resulting in relatively large losses; 3. Cleaning the upper roller is side cleaning, from one end of the roller table to the other. When cleaning the roller table, at high temperature, the water is atomized, and the visibility is relatively low, which is prone to leakage and failure; -400℃) state, encountering cold water impact can easily cause the roller table to crack, causing irreversible damage, only replacement, the cost of replacement is more than 200,000 yuan
