Automatic water supply device of small steam boiler

Abstract

The invention provides an automatic water supply device of a small steam boiler. The automatic water supply device comprises a sealing pipe, a through water storage box, a filter cartridge, a ring groove and a spiral spring; a water supply pump is installed on a through pipe, a stop valve is installed on the through pipe at both ends of the water supply pump, and one end of a water supply pipe communicates with the interior of the water storage box; the water storage box is fixed on a platform, a water inlet pipe at the top of a water inlet and storage tank penetrates through the interior of the sealing pipe, the filter cartridge penetrates through a through hole and is inserted into the inner side of the sealing pipe, and a T-shaped ring pad is inserted into the ring groove through the bottom end of the T-shaped ring pad and mounted at the top end of the filter cartridge; and a fixed cartridge cover is mounted at the bottom of the filter cartridge in a sleeving mode and fixed on the bottom end face of the water inlet and storage tank through bolts. Through the arrangement of the filter cartridge, the filtered water flows out into the water inlet and storage tank to be stored, thelater water supply is more convenient, the filter cartridge is pulled out, washing is more convenient, the spiral spring makes the filter cartridge be attached to the inner end face of the top of thesealing pipe, the T-shaped ring pad is adopted to improve the sealing effect, and the inner quality of the water inlet and storage tank is improved.

Description

technical field [0001] The invention belongs to the technical field of boiler water supply, and more specifically relates to an automatic water supply device for a small steam boiler. Background technique [0002] A small steam boiler refers to a steam boiler with a small evaporation per unit time and a low steam pressure. A small steam boiler generally refers to an inspection-free micro steam boiler with a volume of less than 30 liters. It is easy to use and easy to install. It only needs to be connected to the power supply, water source and heat source. The installation and use are not supervised by the technical supervision department. [0003] The inventor found similar patents in the process of searching for patents. For example, in the Chinese patent application number: 201220046981.X, an automatic water supply system for a circulating fluidized bed boiler is disclosed, including a boiler with a steam drum on the top of the boiler. There is a gas collection box next t...

Problems solved by technology

[0004] Based on the above, the inventors found that the traditional water supply device for small boilers filters tap water into the small boilers while filtering, and the filtering speed is relatively slow, which affects the water supply rate of the small boilers and also affects the filtering effect, reducing the use of small boilers Long life, single function, no matter how much water is lacking in the small boiler, it needs to start the water pump to supply water
