Clean water feeding filter for irrigation

Abstract

The utility model discloses a clean water feeding filter for irrigation. The clean water feeding filter comprises a tank body with supporting legs, a cover body detachably connected to the upper end of the tank body, a water outlet pipe arranged on the lower portion of the tank body and a water inlet pipe arranged on the upper portion of the cover body. An inclined filter screen is arranged in the tank body, and ribs for supporting the filter screen are arranged in the tank body; a sewage outlet capable of being opened and closed is formed in the lower side of the filter screen on the tank body; and the drain outlet is used for discharging intercepted substances deposited above the filter screen. The filter screen has the advantages that the inclined filter screen has a larger filtering area, so that the filter screen is not easy to block. The intercepted objects intercepted on the filter screen can be driven by water flow to settle to the lower end of the filter screen along the inclined surface of the filter screen, and the sewage draining exit can be opened regularly to discharge the intercepted objects settled above the filter screen, so that the filter screen is ensured not to be blocked after being used for a long time.

Description

Technical Field

[0001] The utility model relates to the technical field of irrigation filtering equipment, in particular to a clean water supply filter for irrigation. Background Art

[0002] As a widely used water treatment equipment, mesh filter plays an important role in agricultural irrigation, industrial water pretreatment, swimming pool water circulation filtration and household water purification. This type of filter mainly uses the filter mesh set inside as the filter medium to filter the water flowing through it to remove fine sand, suspended particles, algae and other fine impurities in the water.

[0003] Traditional mesh filters usually consist of a housing, an inlet pipe, an outlet pipe, and a replaceable or cleanable filter. The working principle is to physically intercept water from the outside to the inside through a filter with a certain aperture specification, thereby intercepting particles larger than the aperture of the filter and achieving preliminary purification of the water quality. In actual use, the filter will become clogged as the use time increases, and the filter needs to be disassembled regularly for cleaning and replacement, resulting in increased maintenance costs. Utility Model Content

[0009] Preferably, a second inspection port is provided on the tank body below the higher side of the filter screen.

[0010] Preferably, the inclination angle of the filter screen is greater than 30°.

[0011] Preferably, the sewage outlet adopts a manual valve or an electric valve.

[0012] The above technical solution has the following advantages:

[0013] The utility model adopts an inclined filter screen, which has a larger filtering area and is less likely to be clogged. The retained matter on the filter screen can be driven by the water flow to settle to the lower end of the filter screen along the inclined surface of the filter screen, and the sewage outlet can be opened regularly to discharge the retained matter settled above the filter screen, ensuring that the filter screen is not clogged during long-term use.

[0021] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] As shown in the accompanying drawings, a clean water supply filter for irrigation includes a tank body 2 with a support leg 1, a cover body 3 detachably connected to the upper end of the tank body 2, a water outlet pipe 4 arranged at the lower part of the tank body 2, and a water inlet pipe 5 arranged at the upper part of the cover body 3; an inclined filter screen 6 is arranged in the tank body 2, and ribs 7 for supporting the filter screen 6 are arranged in the tank body 2; an openable and closable sewage outlet 8 is arranged on the tank body 2, located on the lower side of the filter screen 6; the sewage outlet 8 is used to discharge the retained matter deposited above the filter screen 6.

[0023] As a further improved technical solution of this embodiment, a perforated plate 9 for buffering water flow is arranged in the cover body 3. The perforated plate 9 can buffer the water inlet of the water inlet pipe 5, so that the water flow in the tank body 2 is more stable, and it is convenient for the retained matter to be deposited on the lower side of the filter screen 6.

[0024] As a technical solution for further improvement of the present embodiment, a first inspection port 10 is provided on the cover body 3. When the filter is used for a period of time, some sticky impurities will adhere to the filter. At this time, the water inlet of the water inlet pipe 5 can be closed, the water in the tank body 2 can be discharged, and the sewage outlet 8 can be opened. Then, a high-pressure water spray pipe is extended from the first inspection port 10 into the tank body 2 to flush the upper surface of the filter 6. The impurities adhered to the upper surface of the filter 6 will reach the sewage outlet 8 along the inclined surface of the filter 6 and be discharged through the sewage outlet 8.

[0025] As a technical solution for further improvement of the present embodiment, a second inspection port 11 is provided on the tank body 2, below the higher side of the filter screen 6. When impurities such as sand clog the filter screen 6, there is no need to open the cover body 2 to remove the filter screen. At this time, the water inlet of the water inlet pipe 5 can be closed, the water in the tank body 2 can be discharged, and the drain port 8 can be opened. Then, a high-pressure water spray pipe can be extended into the tank body 2 from the second inspection port 11 to flush the lower surface of the filter screen 6. The sand clogged in the filter screen 6 can be flushed upward and discharged along the inclined surface of the filter screen 6 to the drain port 8.

[0026] In this embodiment, the inclination angle of the filter screen 6 is greater than 30°, which increases the filter screen area and facilitates the deposition of intercepted matter on the filter screen 6 .

[0027] In this embodiment, the sewage outlet 8 adopts a manual valve, and it is obvious that an electric valve or other form of sewage outlet may also be adopted.

[0028] The utility model adopts an inclined filter screen 6, which has a larger filtering area and is less likely to be clogged. The retained matter on the filter screen 6 can be driven by the slow water flow along the inclined surface of the filter screen 6 to the lower end of the filter screen 6, and the sewage outlet 8 can be opened regularly to discharge the retained matter settled above the filter screen 6, ensuring that the filter screen 6 is not clogged during long-term use.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
