Description

Technical Field

[0001] The utility model relates to the technical field of wastewater purification and liquid supply systems, in particular to a wastewater purification and liquid supply system for the production of thermos flasks. Background Art

[0002] Thermos liner, also known as the liner of a thermos, is usually composed of two thin glass shells and a vacuum layer in the middle, while the inner side of the glass shell is coated with a layer of silver or other metal reflective film. This design makes the thermos liner have a good heat preservation effect. The silver plating of the thermos liner is to improve the heat preservation performance, antibacterial and antioxidant properties, reduce heat radiation and heat loss; and silver plating is a mature thermos liner coating process with low cost, which makes the glass thermos have a cost advantage.

[0003] The production of the thermos flask liner is to pour a certain amount of silver ammonia complex solution and an aldehyde solution as a reducing agent into the interlayer of the flask blank through a small tail tube to carry out a silver mirror reaction. The silver ions are reduced and deposited on the glass surface to form a thin layer of mirror silver film. The tail tube of the silver-plated double-layer flask blank is connected to the vacuum system and heated to 300-400℃ to cause the glass to release various gases and residual moisture adsorbed. At the same time, the vacuum pump is used to evacuate the air. When the vacuum degree of the interlayer space of the flask reaches 10-3~10-4mmHg, the tail tube is sealed. Since there are toxic and harmful substances in the silver plating process liquid, untreated wastewater cannot be discharged directly into the environment.

[0004] In addition, both the operating wastewater during processing and the cleaning wastewater after processing need to be filtered and processed before they can be discharged. Therefore, purification equipment will be used. However, the existing purification equipment liquid supply system structure has the following deficiencies: three groups of liquid cylinders with 10% sodium carbonate solution, 4% hydrochloric acid solution, and 5% glucose solution are manually weighed and loaded with medicine materials, and the valve is manually opened to add dilution water, and the amount of water is determined by the operator based on experience. When stirring, the stirring time and frequency are also determined based on experience. Finally, the pump is introduced into the purification equipment for purification treatment. It can be seen that such operation has many human uncertainties, and the labor intensity of the operator is high and the technical requirements are high. Therefore, there is an urgent need for a wastewater purification and liquid supply system for the production of thermos flasks to solve the above technical problems. Utility Model Content
