Saline-alkali soil improvement and salt elimination device

Abstract

The invention discloses a saline-alkali soil improvement and salt elimination device which comprises a base, a swing barrel is fixed to the base, the top of a swing rod is welded to the center of theouter bottom of the swing barrel, the lower portion of the swing rod abuts against a protruding piece, an output shaft of a driving motor is sleeved with the protruding piece, and a base bolt of the driving motor is fixed to the lower surface of a top plate. Springs are arranged on the left and right sides of the swing rod, the upper ends of the springs are welded to the bottom of the swing barrel, and the lower ends of the springs are welded to the upper surface of the top plate. Two filter plates, namely a first filter plate and a second filter plate, are arranged in the swing barrel, a drain pipe is glued and fixed in the swing rod, the drain pipe is communicated with the inner bottom of the swing barrel, and a water valve is mounted on the drain pipe; through swinging, sludge and waterare subjected to solid-liquid separation, the purpose of dehydration is achieved, and large substances in the sludge are conveniently separated through multi-layer filtration; and through a detachable structure, the cleaning becomes convenient.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to an improved salt discharge device for saline-alkali land. Background technique [0002] At present, the common soil salt removal measures are mostly to dissolve the soil with water to form a sludge structure, so that the metal ions in the sludge are dissolved in the water, and then the sludge-water separation method is used to reduce the metal salt ion content in the soil. The current sludge treatment Due to the inability of the equipment to treat the sludge, there is more and more residual sludge. These sludges are often wet and have a high moisture content, which greatly increases the difficulty of sludge transportation, and the sludge has a wide range of resources and energy. Therefore, it is necessary to dehydrate the sludge. However, most of the existing sludge plants do not remove impurities from the sludge, resulting in large stones and other substances in the sludg...

[0002] At present, the common soil salt removal measures are mostly to dissolve the soil with water to form a sludge structure, so that the metal ions in the sludge are dissolved in the water, and then the sludge-water separation method is used to reduce the metal salt ion content in the soil. The current sludge treatment Due to the inability of the equipment to treat the sludge, there is more and more residual sludge. These sludges are often wet and have a high moisture content, which greatly increases the difficulty of sludge transportation, and the sludge has a wide range of resources and energy. Therefore, it is necessary to dehydrate the sludge. However, most of the existing sludge plants do not remove impurities from the sludge, resulting in the appearance of large stones and other substances in the sludge. The sludge is easy to dry in the drying plant There are agglomerations and sticky walls, and most of the equipment is made in one piece and the structure is complicated and not easy to clean
