DETAILED DESCRIPTION

[0019] The integrated water-saving irrigation filtering station of the utility model will be described in more detail below in conjunction with the schematic view, wherein the preferred embodiment of the utility model is represented, and it should be understood that the utility model described herein can be modified by those skilled in the art, and the advantageous effects of the utility model can still be achieved, therefore, the following description should be understood as extensive knowledge for those skilled in the art, and not as a limitation of the utility model.

[0020] For example, Figure 1 and 2As shown, an integrated water-saving irrigation filter station comprises a box, a water inlet 1, a first water inlet main pipe 2, an exhaust valve 3, a sand filter two-position three-way valve 4, a sand filter 5, a sand filter backwash drain pipe 7, i.e., a first backwash drain pipe, an automatic backwash controller 8, a second water inlet main pipe, a laminated filter two-position three-way valve 10, a laminated filter 11, a laminated filter backwash drain pipe 12, a water outlet main pipe 13, a water outlet 14, a box corner piece 15, and a door 16.

[0021] The working principle of the integrated water-saving irrigation filter station is as follows:

[0022] The filtering process of the integrated water-saving irrigation filter station is divided into two stages, the first stage is the sand filter 5 for primary filtering, and the second stage is the laminated filter 11 for fine filtering, and the two-stage filtering is integrated in a box which can be hoisted as a whole, and the water inlet and outlet 14 are reserved outside the box.

[0023] The specific process of raw water filtering is as follows:

[0024] The raw water enters the first water inlet main pipe 2 from the water inlet 1, and the air entrained and separated in the water is discharged to the atmosphere by the exhaust valve 3, and the water enters the sand filter 5 through the sand filter two-position three-way valve 4, and under the action of pressure, the impurities (particulate matter, algae, etc.) in the water are intercepted, and the filtered water is collected into the sand filter outlet main pipe 6, and the first-stage filtering of the filter is completed.

[0025] With the passage of time, the impurities in the filter continue to accumulate, resulting in gradually increasing hydraulic loss of water flowing through the sand filter 5 and the laminated filter 11. When the automatic backwash controller 8 detects that the hydraulic loss of the sand filter 5 exceeds the set value, it sends a signal to each sand filter two-way three-way valve 4 one by one, switches the switch direction of the filter two-way three-way valve 4, connects the sand filter 5 with the sand filter backwash drain pipe 7, and sequentially completes the backwash of each sand filter 5; when the automatic backwash controller 8 detects that the hydraulic loss of the laminated filter 11 exceeds the set value, it sends a signal to the laminated filter two-way three-way valve 10 one by one, connects the laminated filter 11 with the laminated filter backwash drain pipe 12, and sequentially completes the backwash of each laminated filter 11. Since there are multiple filter units in the two-stage filtration, the backwash of a single filter does not affect the filtration, and thus the entire backwash is completed.

[0026] The automatic backwash controller 8 has a remote communication function, and can remotely view the filter running state through an app and issue instructions to perform backwash operation on each filter unit.

[0027] The external structure of the utility model is shown in Figure 2 The two-stage filtration and the integrated controller are controlled and integrated in a box body, and all are directly assembled, inspected, pressure tested, and run and debugged in a factory; the four corners of the box body are provided with box body corner pieces 15, so that the box body can be integrally transported and hoisted, and can be put into operation by connecting pipelines on site, and recycling and shifting are facilitated; the box body is provided with an independent door 16, so that the equipment is separated from the external environment, the safety of the equipment is ensured, and non-professional personnel are prevented from misoperation.

[0028] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any way. Any person skilled in the art can make any form of equivalent replacement, modification or change of the technical scheme and technical content disclosed in the utility model without departing from the scope of the technical scheme of the utility model, and such change still belongs to the protection scope of the utility model.
