Filter device for saline-alkali land

Abstract

The invention discloses a filter device for saline-alkali land. After being filtered by a precipitate filter mechanism and a stirring filter mechanism which is communicated with a connection water pipe net, saline-alkali water is used through a water outlet pipe and can also be stored in a water collection groove for standby through a water collection pipe, and a water resource is saved; the connection water pipe net is connected with a three-way joint with the shape adapted to the shape of multiple connection water pipes through the connection water pipes to be in a bow shape, so that with the arrangement structure, the flowing time of the saline-alkali water is prolonged, and impurities which flow into the stirring filter mechanism are reduced; each connection water pipe comprises a semicircular upper pipe and a rectangular lower pipe which is detachably connected with the semicircular upper pipe fixedly; the bottom surface of each rectangular lower pipe is divided into a first rectangular lower pipe bottom slanting surface and a second rectangular lower pipe bottom slanting surface which are mutually connected in a water flow direction, the two edges of each bottom surface are relatively high, the middle part of each bottom surface is relatively low, the adjacent part of each front portion and the corresponding back portion protrudes downward, and each protrusion position isconnected with a collection groove used for collecting precipitates; and the connection water pipes are separated and cleaned separately, the upper pipes are opened, the lower pipes are cleaned, andblockage is prevented.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement equipment, and in particular relates to a filter device for saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation. Because saline-alkali soil contains saline-alkali components, the survival rate of plants planted in saline-alkali soil is low. Therefore, the improvement and utilization of saline-alkali soil is related to the development of urban economy and ecology. Improvement of the environment. The current improvement methods for saline-alkali land are washing salt with water, backfilling with foreign soil, and planting green plants. Plant growth also needs the water required for plant irrigation and growth, so the irrigation link is particularly important. Due to the relative scarcity of fresh water resources in saline-alkali areas, it is necessary to develop a saline-alkali water pipe filter device that can effectively filte...

Problems solved by technology

[0004] Although the above-mentioned filter device has played a certain role in filtering, the sedimentation filter is not thorough, and the sediment in the water pipe connecting the sedimentation filter device and the agitation filter device is not easy to clean, and it is easy to cause blockage of the water pipe
