Technical Field
[0001] The utility model relates to the technical field of boilers, in particular to a boiler water supply device which is convenient for replacing a filter screen. Background Art
[0002] The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler includes two parts: pot and furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. The quality of water in the boiler feed water is one of the important factors affecting the safe and economical operation of boiler equipment. A filter is usually set in the boiler feed water device to pre-treat the water source to avoid scale formation on the heating surface of the boiler due to poor water source, causing damage to the boiler and waste of energy. After the filter is fixed in the feed water device, it is generally not easy to remove and replace it quickly. When replacing the filter, it is generally necessary to stop filtering the water, which affects the filtering work. Therefore, a boiler feed water device that is easy to replace the filter is proposed to facilitate the replacement of the filter without affecting the filtering work. Utility Model Content

[0022] When in use, open the first valve 6 and close the second valve 7. Water enters the cylinder 14 far away from the drain valve 13 through the water inlet pipe 8, the first valve 6, and the conduit 15. The filter screen 19 filters the water. The filtered water is collected inside the box 1. Open the drain valve 13 to supply water to the boiler. When it is necessary to replace the filter screen 19 far away from the drain valve 13, close the first valve 6 and open the second valve 7 at the same time.

The filter 19 filters the water, and the filtered water is collected inside the box 1. The drain valve 13 is opened to supply water to the boiler;
[0029] When it is necessary to replace the filter screen 19 far away from the drain valve 13, close the first valve 6 and open the second valve 7 at the same time. Water enters the cylinder 14 near the drain valve 13 through the water inlet pipe 8, the connecting pipe 10, the second valve 7, and the bent pipe 16. The filter screen 19 near the drain valve 13 filters the water. The piston rod of the hydraulic cylinder 5 far away from the drain valve 13 drives the pressure cover 3 to move upward, and the vertical rod 17 and the pressure ring 18 move upward accordingly. At this time, the pressure ring 18 no longer squeezes the filter screen 19, which facilitates the removal and replacement of the filter screen 19 without affecting the filtering work.
