Description

Technical Field

[0001] The utility model relates to the technical field of steam generation, in particular to a steam generator. Background Art

[0002] Steam generator, as an efficient and environmentally friendly heating equipment, plays an important role in modern industrial production and life. It achieves the purpose of heating by heating water to boiling and generating steam. Steam generator has the advantages of high thermal efficiency, energy saving and environmental protection, safety and reliability. It is widely used in food processing, pharmaceutical manufacturing, textile printing and dyeing, chemical industry and other industries. Compared with traditional hot water heating methods, steam generator has higher thermal efficiency and can quickly transfer heat to objects to achieve rapid heating. At the same time, during the operation of the steam generator, there is no need for direct contact with the heated object, which effectively reduces safety hazards. As an efficient and environmentally friendly heating equipment, steam generator has broad application prospects in various industries. With the continuous innovation of technology and the development of industry, steam generator will make greater contributions to the sustainable development of my country's economy and society.

[0003] According to the search of China Utility Model Publication No.: CN212081190U, a steam generator is disclosed. 1. When the steam generator is used, water is injected into the water tank through the water inlet, and the heater is started. The heater heats the water to generate water vapor. The water vapor evaporates and enters the concave plate through the air outlet net, and then enters the air outlet pipe for discharge. At the same time, the air pump is started, and the air pump sends air through the first hollow tube into the second hollow tube, and finally discharged into the water tank to increase the air content in the water tank, thereby achieving the purpose of increasing water vapor. When scale is generated during long-term use, the motor is started, and the motor drives the rotating shaft to rotate. The rotating shaft drives the descaling blade to rotate through the connecting rod to remove the scale attached to the insulation layer and the side wall of the heater. At the same time, the ultrasonic generator is started, and the ultrasonic generator generates ultrasonic waves to remove scale, thereby improving the removal efficiency. After the removal is completed, the rotary switch is turned on, and the scale is discharged through the discharge port. 2. The steam generator has a water level sensor at the bottom of the isolation plate. When the water level sensor senses that the amount of water in the water tank is too little, the heater stops working to reduce safety hazards.

[0004] However, there are some issues that need to be considered when implementing the above technical solution: First, when adding water to the generator, cold water directly enters the evaporation tank, which will instantly lower the water temperature and affect the continuity of steam generation; second, the generator uses a blade to remove scale attached to the insulation layer and the side wall of the heater, but the blade will scratch the inner wall, causing scale to adhere more easily to the inner wall, increasing the difficulty of cleaning.
