Embodiment 1

[0020] The present invention provides such Figure 1-3 The one shown is a multi-layer filter device suitable for saline-alkali land, which includes a filter body 1 pre-buried in saline-alkali land and a cleaning tank 2 half-buried in saline-alkali land. The inner cavity of the filter body 1 is composed of a permeation tank 3 and a filter layer 4 , and the filter layer 4 is arranged on the top of the permeation tank 3, the filter element 5 is movable in the permeation tank 3, the bottom of the permeation tank 3 is fixedly provided with a guide rail 6, and the top of the guide rail 6 is provided with a guide groove 7, and the guide groove The bottom end of 7 extends to the inner cavity of the guide rail 6, and the top of the guide groove 7 is movably connected with an L-shaped push plate 8, and the L-shaped push plate 8 is arranged at the bottom of the filter element 5, and a residue outlet is provided on one side of the permeation tank 3 9. The other end of the residue outlet 9...

Embodiment 2

[0023] The difference with embodiment 1 is:

[0024] Further, in the above solution, the filter layer 4 includes a first filter layer 41, a second filter layer 42 and a third filter layer 43, and the first filter layer 41, the second filter layer 42 and the third filter layer 43 Arranged sequentially from top to bottom, the first filter layer 41 is made of pebbles with a diameter of 2cm-4cm, and the second filter layer 42 is made of quartz sand with a diameter of 0.3cm-0.5cm. The third filter layer 43 is made of activated carbon with a diameter of 0.08cm-0.1cm, which is beneficial to filter the soil and large granular impurities in the dissolved water, so that relatively clean dissolved water passes through the filter layer 4 The filtered permeate enters the permeation tank 3.

[0025] In the above scheme, it is beneficial to filter the saline, microparticles and bacteria contained in relatively clean dissolved water, so as to obtain fresh water for reuse.

[0026] In the ab...

Abstract

The invention discloses a multilayer filtering device suitable for saline-alkali soil. The device comprises a filtering main body pre-buried in saline-alkali soil and a cleaning tank semi-pre-buried in the saline-alkali soil, an inner cavity of the filter body is composed of a permeation groove and a filter layer, the filter layer is arranged at the top end of the permeation groove, a filter element is movably arranged in the permeation groove, a guide rail is fixedly arranged at the bottom of the permeation groove, a guide groove is formed in the top of the guide rail, and the bottom end of the guide groove extends into the inner cavity of the guide rail. According to the invention, soil and large granular impurities in dissolved water are filtered through the filter layer, so that relatively clean dissolved water is filtered by the filtering layer and permeates into the permeation tank; and then fresh water is obtained through filtration and permeation of the deep layer of the filterelement; therefore, the recycling effect is achieved and water resources are saved accordingly; meanwhile, saline-alkali, micro-particles and bacteria obtained after filtration of the filter elementare pushed to a residue hopper in the cleaning tank through an L-shaped push plate, and saline-alkali, micro-particles and bacteria are cleaned.

Description

technical field [0001] The invention relates to the field of saline-alkali land improvement equipment, in particular to a multi-layer filter device suitable for saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. Generally, saline-alkali land can achieve the effect of washing salt on saline-alkali soil through water, but the existing improvement methods use water to improve saline-alkali land. When the saline-alkali in the soil is washed, the dissolved water obtained after washing the salt will enter the deep layer of the soil. When it is relatively dry, the dissolved water in the deep layer will re-enter the soil surface along with the soil capillary, so that the improved saline-alkali land will return to saline. Therefore, the treatment of dissolved water is an important problem to solve the saline-alkaline land. The existing technology gener...
