Problems solved by technology

[0006] The first defect is low production efficiency: the single-station chemical furnace only includes a preheating box and an exchange furnace. While the product is being chemically tempered, it cannot preheat the next batch of glass to be strengthened, and must wait for the product The next batch of products can be strengthened only after the complete strengthening is completed. The waiting period is long and the production efficiency is low.
[0007] The second defect is low yield rate: the chemical furnace of the prior art usually uses a motor to drive the wire rope of the shutter machine to lift and lower the hanging basket to complete the glass entering and exiting the furnace. Vibration is large, resulting in contact displacement between glass and tooling, which is prone to defects and low yield
[0008] The third defect is that the replacement of parts is complicated: the heating system in the chemical furnace of the prior art is usually a built-in structure, and electric heating wires or electric heating tubes are arranged inside the box body, long-term thermal fatigue and components Aging will cause the heating system to fail, and it is complicated to replace the heating system parts during maintenance
[0009] The fourth defect, the temperature of the exchange solution is not uniform: the heating system in the chemical furnace of the prior art is usually placed on both sides and the bottom of the salt tank furnace wall, heating the three sides, heating up and keeping the alkaline salt solution through heat transfer, because The volume of the furnace body is relatively large, and the temperature of different positions in the furnace body is limited to the heat transfer of each part of the salt solution to maintain a uniform temperature
[0010] The fifth defect is poor heat preservation effect: in the chemical furnace of the prior art, it is usually used in the furnace wall, the cover plate of the salt tank, and the joints of the heating pipes and other places that are prone to heat loss are plugged with heat preservation cotton to achieve the effect of heat preservation , but no measures have been taken for the heat preservation at the connection position of the transmission system, resulting in the loss of heat from the transmission system during the transmission process, resulting in uneven temperature
[0011] The sixth defect, short service life: the working temperature of the chemical furnace in the prior art is usually 350-450 degrees Celsius, and the parts will be in a high temperature state for a long time, and bear a large thermal load and long-term fatigue load, especially the transmission system. Parts will often fail due to long-term work, resulting in frequent replacement of parts and shortening the service life of the chemical furnace
[0012] The seventh defect is poor product performance monitoring: most of the strengthening salts used in chemical furnaces in the prior art are nitric acid or nitrous acid alkaline salts, and ion exchange with glass for a long time will lead to a decrease in the purity of the salt solution, which cannot reach Good strengthening effect, in the process of glass strengthening, the strengthening effect of the glass cannot be monitored online, and it is impossible to judge whether the glass has reached the corresponding strength index
