Embodiment

[0044] This embodiment provides a filtering device, such as Figure 1-3 As shown, it includes: a filter element 1, which is suitable for communicating with the water suction port 81 of the water suction pipe 8, and is used to filter the water before the water enters the water suction port 81; The filter element 1 is connected and can float in the water, and is used to pull the filter element 1 so that the filter element 1 is in the middle layer of the water.

[0045] In the filter device of this embodiment, the filter element 1 and the floating element 2 are connected together, and the floating element 2 is used to control the filter element 1 so that it is in the middle layer of the water. Since the water impurities in the middle layer are less, the speed of the filter element 1 to filter water Quickly and without frequent cleaning of the filter element 1 . The length of the connecting part 12 is adjustable, so that the height of the filter part 1 from the bottom of the wate...

Abstract

The invention discloses a filter device. The filter device comprises a filter piece and a floating piece; the filter piece is suitable for communicating with a water sucking port of a water sucking pipe, and is used for filtering water before the water enters the water sucking port; and the floating piece can float in the water, and is connected with the filter piece through a connecting piece for pulling the filter piece to enable the filter piece to locate on a middle layer of the water. The filter device connects the filter piece with the floating piece, and uses the floating piece for controlling the filter piece to locate on the middle layer of the water; and as impurities in the water on the middle layer are fewer, the filter device is faster in water filter speed, and needs no frequent cleaning.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device for filtering water entering a water inlet pipe of a self-priming pump. Background technique [0002] In some applications, it is necessary to use a self-priming pump to draw water from the water source. The structure of the existing self-priming pump is relatively delicate, and the diameter of the water inlet pipe used for water absorption is also small. When the water contains impurities, if the water source is not filtered, the impurities will follow the water into the water inlet pipe, not only it is easy to block the water suction pipe, It can also cause damage to the self-priming pump. [0003] In the prior art, a common solution is to install a filter screen at the water inlet of the water inlet pipe. The filter screen is used to filter the water entering the water inlet pipe to prevent the water inlet pipe from being blocked or the self-priming pump from being damaged. ...
