Description

Farmland drip irrigation cyclone sand remover

technical field

The utility model relates to a swirl sand remover for farmland drip irrigation. the

Background technique

China is a big agricultural country, and it is also a big water-scarce country, especially in the arid regions of the central and western regions. This also forces us to adopt drip irrigation technology more and more in agricultural production. A lot of water used for drip irrigation carries a lot of sediment. Sediment will block the valve and the drip irrigation belt. Therefore, a simple cyclone desander, commonly known as the "drip irrigation head", is often used at the head of the drip irrigation to perform simple desanding treatment on the drip irrigation water. The swirl bin of the sand container rotates behind, and the sediment gathers on the side wall of the swirl bin under the action of centrifugal force. The lower part of the swirl bin is an inverted cone-shaped bell mouth structure. Under the action of the action of the water, it enters the sedimentation bin to settle, so as to purify the water. This treatment method is simple and effective. However, when the water passes through the inverted cone-shaped bell mouth, the speed increases, and the sediment moves along the side of the bell mouth under the action of centrifugal force. The high-speed rotation of the wall makes the inverted cone bell mouth, especially the side wall of the lower part of the inverted cone bell mouth, wear quickly, and often wears through the bottom of the bell mouth of the cyclone desander, causing the entire equipment to be scrapped. If it needs to be repaired, It is necessary to cut off the bell mouth and then weld a new bell mouth. Under the environment of field work, cutting and welding the bell mouth are all inconvenient, time-consuming, laborious, and cause unnecessary waste. the
