Isothermal-isobaric multipurpose thermal tempering equipment for ultra-thin glass

Abstract

The invention discloses isothermal-isobaric multipurpose thermal tempering equipment for ultra-thin glass. The equipment comprises an upper piece platform, a heating furnace, a tempering section, a lower piece platform, a draught fan, a draught fan pipeline system and an electrical control system, wherein the draught fan is connected with the tempering section through the draught fan pipeline system and is used for continuously and uniformly supplying wind to the tempering section, a glass preheating region, a glass softening region and a glass stabilizing region are respectively arranged in the heating furnace, and the tempering section is divided into a glass shaping region and a glass tempering region. The isothermal-isobaric multipurpose thermal tempering equipment is provided with the glass preheating region and the glass stabilizing region, so that the adequate and uniform heating of glass is guaranteed; by utilizing an upper-lower duel roller bed, the glass deformation in the heating process can be furthest reduce; and furthermore, the upper-lower duel roller bed type glass shaping region is arranged at the tempering section, so that the softened glass can be shaped before being tempered, and the flatness of the softened glass reaches the standard requirement of tempered glass. The isothermal-isobaric multipurpose thermal tempering equipment has multiple purposes of flattening and bending and can be used for producing flat and bent tempered glass of various specifications and shapes.

AI Technical Summary

Problems solved by technology

[0006]It is difficult to guarantee the quality of tempered glass by using traditionally designed glass tempering equipment to produce ultra-thin tempered glass below 2.5mm. First, the cooling capacity of the tempering section is limited, and the cooling speed cannot reach To meet the requirements for the production of ultra-thin tempered glass; second, the control system cannot control the tempering equipment to control the production cost based on the production process, and the personal subjective consciousness of the operator controls the production cost to a large extent, resulting in unstable temperature in the heating furnace. This leads to uneven heating and affects the quality of the tempered glass; third, the ultra-thin glass is heated rapidly in the heating furnace, causing the glass to undergo a large deformation, while the traditional tempering equipment does not preheat the glass and stabilize it after heating, resulting in flat glass Fourth, the distance between the conveying rollers of traditional tempering equipment is large, which cannot ensure that the heated glass does not deform; fifth, there is no glass shaping treatment in the tempering section, and the cooling is uneven, resulting in increased glass deformation; sixth, the fan duct The road system is not designed with an airflow rectification device. The airflow at the fan outlet is sent to the air grille before it reaches a stable state. The airflow cannot be evenly distributed to each position of the air grille, and the glass cannot be cooled uniformly, which affects the quality of glass tempering.

Seventh, the air pressure of the cooling medium provided by the fan is low, the temperature is high, and the flow rate is slow, resulting in insufficient cooling capacity

Eighth, the cooling medium is affected by the seasonal and temperature changes of the place of use, and the temperature and pressure of the medium change greatly, resulting in unstable quality of tempered glass

Ninth, the production function of traditional glass tempering equipment is single, flat and curved tempered glass cannot be produced by the same equipment
