Embodiment 1

[0049] Such as figure 1 and figure 2 As shown, the embodiment of the present disclosure provides a filtering structure 1 . The filtering structure 1 includes a housing 100 , a flow guide 200 , a central pipe 300 and a lamination assembly 400 . Through the cooperation of various components, the filtering structure 1 of this embodiment realizes rapid filtering of water.

[0050] Such as image 3 and Figure 4 As shown, the housing 100 is approximately cylindrical in shape and has a cavity 110 inside. The top of the cavity 110 is provided with an opening 120 , and the bottom of the housing 100 is a sewage outlet 130 communicating with the cavity 110 .

[0051] Optionally, a top end of the outer wall of the housing 200 is provided with a first external thread 160 . The first external thread 160 is used for connecting the housing with other components. A flange 170 extends radially from below the first external thread 160 .

[0052] Such as Figure 5-7 As shown, the cente...

Embodiment 2

[0072] Such as Figure 13 As shown, the filter structure 2 of this embodiment is the same as the housing 100 , the flow guide 200 , the central pipe 300 and the drain valve connector 500 of the filter structure 1 in the first embodiment.

[0073] The lamination assembly 400 includes a plurality of laminations which are sequentially sleeved on the central pipe, and water enters the central pipe through the filter gap of the lamination assembly.

[0074] Such as Figures 14 to 16As shown, the lamination in this embodiment is the lamination 400b. The lamination 400 b includes an annular portion 410 and a conical portion 420 . The structure of the ring portion and the truncated portion of the present embodiment is the same as that of the first embodiment. The central tube 300 passes through the through hole 411 , and a plurality of laminations 400 b are sheathed on the tube body 310 in sequence. A plurality of laminations 400b are stacked from bottom to top, and the supporting...

Embodiment 3

[0081] Such as Figure 17 As shown, this embodiment provides a pre-filter. The pre-filter includes: an end cover 700 , a filter structure and a drain valve 800 . The filtering structure can be the filtering structure 1 of the first embodiment, or the filtering structure 2 of the second embodiment. The end cap 700 is located at the top of the filter structure, and the drain valve 800 is located at the bottom of the filter structure.

[0082] Such as Figure 18 and Figure 19 As shown, the top end of the housing 100 penetrates the bottom end of the end cap 700, and the bottom end of the end cap 700 is provided with an internal thread, and the internal thread of the end cap 700 is connected with the first external thread 160 of the housing to realize the end cap 700 and Connections for filtering structures. The flange 170 limits excessive penetration of the housing 100 into the end cap 700 . The end cover 700 includes a water inlet 710 and a water outlet 720 , the water inl...

Abstract

The disclosure relates to a filtering structure, a pre-filter and a filtering method. The filter structure includes: a shell, a cavity with an open top inside, and a sewage outlet at the bottom; a flow guide, including an outlet flow channel arranged in the axial direction and an inlet flow channel located outside the water outlet flow channel, and the flow guide member closes the shell The top opening of the body, the water inlet channel and the water outlet channel are respectively connected to the cavity; the central tube includes the tube body and the supporting plate; there are multiple water inlets on the side wall of the tube body, and the water outlet is provided on the top; the supporting plate is located on the tube The bottom end of the body; the center pipe is located in the cavity, the top is connected to the flow guide, and the water outlet of the center pipe is connected to the water outlet channel of the flow guide; the lamination assembly includes a plurality of laminations that are sequentially sleeved on the center pipe, Water enters the central tube through the filter gap of the lamination assembly. The filtration structure of the present disclosure improves the separation efficiency of impurities through multi-stage separation, and the components are not easy to be blocked.

Description

technical field [0001] The disclosure belongs to the field of filtering equipment, and in particular relates to a filtering structure, a pre-filter and a filtering method. Background technique [0002] The pre-filter can be used to filter large particles such as sediment and rust in tap water. The pre-filter is generally installed at the forefront of the water pipeline. The pre-filters currently on the market are usually filtered by a filter screen. After a period of use, the filter screen in the pre-filter will be blocked by some fine sand or other impurities, and it needs to be cleaned. When cleaning the filter screen, use direct flushing to wash off the impurities attached to the filter screen with the help of the momentum of the water flow, and then discharge them from the drain valve. However, it is difficult to completely wash away the impurities blocked in the steel mesh, and long-term use will reduce the water flux. Contents of the invention [0003] The purpose...
