The drain pipe is welded to the upper front end of the filter barrel, the filter stone is placed inside the filter barrel, and the sealing cover is fixed to the top of the filter barrel by screws.

[0006] Preferably, the sealing cover is provided with a guide bushing and a spring. The guide bushing is distributed in a quadrilateral shape and is fixed to the bottom periphery of the sealing cover by screws. The spring is fixed to the bottom center of the sealing cover by screws, and a fine filter screen is fixed to the bottom of the spring by screws.

[0007] Preferably, the top periphery of the fine filter screen is quadrilaterally distributed and fixed with guide shafts by screws, and the upper end of the guide shaft is nested in a guide shaft sleeve.

[0008] Preferably, a sealing ring is fitted on the outer side of the fine filter screen.

[0009] Compared with existing technologies, the advantages of this utility model are as follows: a coarse filter screen is placed between the filter tank and the sedimentation tank, which can be used for coarse filtration of water; a fine filter screen is fixed to the bottom of the spring by screws, which can be easily driven by the spring to squeeze and fix the filter stone; the upper end of the guide shaft is nested in the guide shaft sleeve, which allows the fine filter screen to move up and down along the guide shaft sleeve; in summary, this utility model can easily filter dispersed water sources and effectively improve water supply safety.

Detailed Implementation

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] like Figure 1-3 As shown, a rural water supply device suitable for decentralized water sources includes a sedimentation tank 1, a filter tank 2, an inlet pipe 3, and a drain valve 4. The filter tank 1 is fixed to the top of the sedimentation tank 1 with screws, and a coarse filter screen 5 is placed between the filter tank 2 and the sedimentation tank 1. A lower sealing gasket 6 is placed between the bottom of the coarse filter screen 5 and the top of the sedimentation tank 1, and an upper sealing gasket 7 is placed between the top of the coarse filter screen 5 and the bottom of the filter tank 2. The inlet pipe 3 is welded to the upper right side of the sedimentation tank 1, and the drain valve 4 is threaded to the lower front end of the sedimentation tank 1. The bottom of the filter tank 2 has an open structure, and a drain pipe 8, a filter stone 9, and a sealing cap 10 are provided on the filter tank 2. The drain pipe 8 is welded to the front end of the filter barrel 2. The filter stone 9 is placed inside the filter barrel 2. The sealing cover 10 is fixed to the top of the filter barrel 2 by screws. The sealing cover 10 is provided with a guide sleeve 11 and a spring 12. The guide sleeve 11 is distributed in a quadrilateral shape and is fixed to the bottom periphery of the sealing cover 10 by screws. The spring 12 is fixed to the bottom middle of the sealing cover 10 by screws. The bottom of the spring 12 is fixed to a fine filter screen 13 by screws. The top periphery of the fine filter screen 13 is distributed in a quadrilateral shape and is fixed to a guide shaft 14 by screws.
