[China Glass Net] Calculated fuel consumption 70.6 tons / day; melting section span 36 meters, elevation 7.52 meters; melting section, card neck, cooling area is 402.42 square meters, the entire kiln depth is 1200 mm, the total content of glass The amount is about 1200 tons; the lower part of the wall of the melting part is inclined casting 33#AZS, the thickness is 300 mm, the wall insulation clay brick is BA-40a, and the thickness is 150 mm. In this operation, the single pipe has no water discharge of about 7 tons per hour during normal operation, and the effective working time is accumulated for 49 hours. Combined with the tin bath pull, the liquid level drops to near the reference position of 510 mm, reaching a preset position. The quenched glass has few large agglomerates, the particle size is mostly below 20-10 mm, and the particle size distribution is relatively uniform.
A manual treatment is required, that is, it meets the requirements for feeding. With this method of operation, the one-time investment is small, and the cost of materials and equipment is only 10,000 yuan. Except for a small amount of materials consumed, most of them can be reused; the installed power of the system is below 70 kW, and the cooling water can be recycled; civil structures, It does not occupy the factory area for a long time; the preliminary work is simple, and the manufacturing and installation cycle is short. Glass kiln pipe water quenching method The essence of water discharge operation is dynamic hydraulic transmission. The pressure water flow is used as the working medium for transmitting power, and the kinetic energy of the moving liquid is used for work. From the perspective of energy conversion, the pump converts the mechanical energy output from the motor into water and enters the pipeline. The pressure of the water in the pipeline can be converted into the kinetic energy of the water. When the high-speed water flows through the transition tank, the impact and the entrainment flow into the tank at the same time. The flow of molten glass passes through the conveying pipe to the separation tank, and the quenched glass falls to the collecting plate, and the water that has lost energy flows into the returning pool.
It is very important to do technical preparation before carrying out the work. There are several geometric parameters that must be considered in the overall design, such as the distribution of the drilling position, the installation angle of the guide groove and the transition groove, etc., which must be controlled within the allowable range of the process. The design tasks of the water supply system are mainly the selection of water supply equipment, the determination of pipe diameter and the arrangement of valves. The basic requirement is to provide sufficient flow and pressure, reliable operation, no pulsation and cavitation, and stable flow and pressure. High sex. The transition tank is the key device in the process system, and the structural design is reasonable, which is directly related to the success or failure of the operation. According to the set release amount and the length of work time, the actual cooling curve is established; the melting temperature should be controlled within a moderate range, the principle is to ensure the liquid flow temperature required for normal operation and avoid excessive fuel consumption.
