A cyclone sand removal and sand filter device for agricultural irrigation

Abstract

The invention discloses a swirl-type sand removing and sand-discharging filtering device for agricultural irrigation, which comprises a water inlet pipe and an outlet pipe installed on an upper cylinder, and a tapered cylinder fixedly installed in a lower cylinder, a partition plate, No. 1 sand filter cartridge, the second cone and the filter screen are fixedly installed in the lower cylinder, and the lower end of the second cone is fixed on the partition plate, and the second cone is a hollow structure with two ends connected, and one The No. 1 filter sand filter is located in the second cone. The advantages are: the overall sand removal and sand discharge operation of the device is simple, and the use cost of the sand discharge operation is relatively low; the irrigation water loss generated during the entire sand removal and sand discharge process is relatively low, and the small particles leaked from the No. 1 sand filter tube The cleaning operation of sand particles is also relatively simple; at the same time, through the cooperation of the second conical cylinder and the filter screen, part of the irrigation water can be directly transported to the drainage pipe for use without being re-transported to the upper cylinder for another sand removal operation after filtration.

Description

technical field [0001] The invention relates to a filter device, in particular to a cyclone type sand removal filter device for agricultural irrigation. Background technique [0002] After searching, the patent authorized invention with the patent number CN106422515B discloses a swirl type sand removal and sand removal filter device for agricultural irrigation, including an upper cylinder and a lower cylinder, and it is characterized in that the upper part of the upper cylinder The front side is fixedly connected with a water inlet pipe, the inside of the upper cylinder is provided with an outlet pipe, the outlet pipe passes through the upper wall of the upper cylinder and the water inlet end of the outlet pipe is located inside the upper cylinder. [0003] But this desanding filter device also has the following deficiencies in the specific use process: [0004] 1. The No. 1 sand filter tube is directly connected with the conical tube and the sand outlet tube, and part of t...

[0006] 3. Through the cooperation of the output pump and the No. 2 water pipe, although the irrigation water flowing from the No. 1 sand filter tube to the conical tube and the partition can be re-transported to the upper tube, but this process will also have some small particles of sand As the irrigation water passes through the No. 1 sand filter cartridge, and then flows together with the water flow, no matter whether the output pump itself has a filter screen or not, this part of the small sand particles has not been well treated. With the filter screen, the small particles The sand particles will eventually remain on the No. 1 water pipe, which is inconvenient to clean. Without a filter, the small particle sand particles will be re-sanded in the cylinder with the water, and the small particle sand particles will not be well cleaned. to remove
