Description

Technical Field

[0001] The utility model belongs to the technical field of boilers, and in particular relates to a steam boiler capable of automatically draining water. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler is in the form of chemical energy in the fuel, electrical energy, thermal energy of high-temperature flue gas, etc., and after conversion by the boiler, steam, high-temperature water or organic heat carrier with a certain amount of thermal energy is output to the outside. At present, the water supply and drainage structure of steam boilers is not only simple in structure, but also cumbersome in operation. It often requires manual operation of water pumps for water supply and drainage. In addition, the existing water supply and drainage structure is prone to backflow, which will bring scale in the boiler into the water pump pipe or valve, affecting the normal operation of the external water pump for a long time.

[0003] For example, the Chinese patent publication number CN212511101U discloses a water supply and drainage device for a steam boiler, comprising a steam boiler body, an inner boiler fixed to one side of the top of the inner cavity of the steam boiler body, a water supply hole opened at the bottom of the inner cavity of the inner boiler, a plug corresponding to the water supply hole provided directly above the water supply hole, a push rod fixedly connected to the middle of the bottom of the plug, a water supply pipe corresponding to the water supply hole fixed to the bottom of the inner boiler, and the lower end of the water supply pipe extending out of one side of the bottom of the steam boiler body.

[0004] This patent has the following problems:

[0005] The prior art documents do not allow for automatic drainage control of steam boilers, which reduces the intelligence of steam boiler drainage. Furthermore, the prior art documents do not allow for the convenient opening and closing of steam boilers for waterproofing, which reduces the stability of steam boiler drainage. In view of this, we propose a steam boiler with automatic drainage. Utility Model Content

[0008] Based on the above structure, the internal stability of the steam boiler is detected by a temperature sensor, and then the electrical equipment is automatically switched on and off using a high-temperature switch, which can automatically control the drainage of the steam boiler, thereby improving the intelligence of the steam boiler drainage. Then, the steam is heated by a heating plate, and then the automatic drainage ball valve is used to drain the water inside the steam boiler, which can quickly drain the steam boiler, thereby improving the stability of the steam boiler drainage.

[0009] Preferably, a fixed lower bracket is fixedly installed on one side of the automatic drainage ball valve, and the fixed lower bracket is made of stainless steel.
