Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

With reference to the attached drawing 1, a conveying pipeline for irrigation comprises a pipeline main body 1, a first-stage filtering part 2 and a second-stage filtering part 3 are arranged on a pipe section of the pipeline main body 1, the first-stage filtering part 2 is used for carrying out primary filtering on a conveying medium in the pipeline main body 1, the second-stage filtering part 3 is used for carrying out secondary filtering on the conveying medium after the primary filtering, the first-stage filtering part 2 is close to the position of the pipeline main body 1 in the incoming flow direction, wherein,

the primary filtering part 2 is detachably arranged on the pipeline main body 1 and comprises a first filtering chamber 21 and a first recovery chamber 22, a filtering cavity 211 and an output cavity 212 which are separated from each other are arranged in the first filtering chamber 21, and the first recovery chamber 22 is connected to the filtering cavity 211 through a first conveying pipe 23 and is used for recovering silt in the filtering cavity 211; the filter cavity 211 and the output cavity 212 are separated by a filter screen 4;

the second-stage filter part 3 is detachably arranged on the pipeline main body 1 and comprises a second filter chamber 31, and a second re-filtering device 32 is arranged in the second filter chamber 31.

On the basis of the prior art, a series of filtering parts are arranged on the water conservancy pipeline, so that the water quality of irrigation and the water quality of the irrigation and the water conservancy pipeline can be filtered to a certain extent, and pure water can be obtained. In addition, in the prior art, particularly for people located along the bank of a river, when irrigation and other operations are carried out by using river water, certain treatment needs to be carried out on water quality, and substances harmful to crops, such as silt and the like in the water, need to be filtered. However, the water conservancy pipeline with the filtering device in the prior art can only filter silt, but cannot recycle the silt, so that certain resource waste is caused. The invention is additionally provided with a recovery device and fine filtration, not only can realize the secondary utilization of resources, but also can expand the application range of the invention.

When the water-saving filter is used, the primary filter part 2 and the secondary filter part 3 are arranged on the pipeline main body 1, two ends of the pipeline main body 1 are connected to a using position, when water flows through the pipeline main body 1, primary filtration of conveyed water is firstly realized through the first filter chamber 21 in the primary filter part 2, and the water-saving filter specifically comprises the following steps: rivers pass through filter chamber 211 and realize filtering, and the silt that filters down passes through conveyer pipe 23 and gets into recovery room one 22, and the rivers after the filtration flow out through output chamber 212, then enter into second grade filter portion 3 along pipeline main part 1 and carry out the refilter, specifically, rivers enter into filter chamber two 31, realize the filtration that becomes more meticulous through its inside refilter device 32.

The first filtering chamber 21 is a hexahedral structure with a sealing cover at the upper part, an overflow port is arranged on the first filtering chamber 21, and a first plug is arranged on the overflow port.

In order to prevent the blockage problem or the overflow problem of silt from the vicinity of the sealing cover in the process of using the filter chamber, an overflow port, specifically a regular shape such as a square shape, a round shape and the like, is arranged at the side part of the filter chamber I21 and near the bottom end, and a first plug for blocking is arranged at the overflow port, so that the silt in the filter chamber I21 which cannot be timely conveyed into the recovery chamber I22 is released by pulling down the plug when the situation occurs, and the normal operation of the filter chamber I is ensured.

As an extension of the invention, the sealing cover can be clamped at the opening of the hexahedral filtering chamber I21, and a handle can be arranged at the upper end of the sealing cover for realizing the purpose of conveniently opening the filtering chamber I21, thereby being convenient to lift.

The first recovery chamber 22 is a cylinder with an opening at the upper part, a discharge opening 22a is further arranged at the side part of the first recovery chamber 22, and a second plug is arranged on the discharge opening 22 a.

Because the silt of retrieving the end contains a certain amount of moisture, in order to conveniently retrieve the lower silt of humidity, consequently the lateral part of retrieving room one 22 and be close to its bottom position and set up the mouth of releasing 22a, specifically be circular through-hole to carry out the processing of releasing water of certain time after retrieving a period, specifically do, pull out stopper two, make the subsidiary moisture in the silt discharge through the mouth of releasing 22 a. Silt in the first recovery chamber 22 can be used for buildings, roads, bridges and the like, and the recovery utilization rate of resources is improved.

As an extension of the structure in the invention, a flexible filter screen with the aperture smaller than that of silt is arranged at the position of the discharge port 22a, so that part of silt is prevented from leaking out in the process of discharging water, and resource waste is avoided.

The filter screen 4 between the filter cavity 211 and the output cavity 212 is clamped in the filter chamber I21, and a clamping groove clamped with the filter screen 4 is arranged in the filter chamber I21 and positioned on the lower end face.

Specifically, the clamping groove is positioned inside the first filtering chamber 21 and at the lower end face, when the filtering chamber is assembled, the filtering net 4 is directly clamped in the clamping groove, and the clamping groove can be of a U-shaped structure; in order to prevent the filter screen from inclining due to the impact of water flow after the filter screen is used for a period of time, an insertion rod can be arranged at the upper end of the filter screen 4 in the using process, and the insertion rod penetrates through the filter screen 4 and then is arranged on the side wall of the filter chamber I21.

The filter screen 4 is used for blocking impurities with the grain diameter larger than the pore diameter of the filter screen 4, such as silt and the like entering the pipeline main body 1 along with water flow, in the filter cavity 211, and the filtered water flow flows out through the output cavity 212 and flows into the secondary filtering part 3 through the pipeline main body 1.

The re-filtering device 32 in the second filtering chamber 31 is set as a pipeline filter.

The first filtering chamber 21, the second filtering chamber 31 and the pipeline main body 1 are all provided with connecting flanges 5.

Can realize detachable the connection between the three through flange 5 and bolt, and it is comparatively convenient to operate.
