An agricultural soil restoration device

Abstract

The invention discloses an agricultural soil remedying device. The agricultural soil remedying device comprises a filter cartridge, wherein a conical funnel body is arranged at the top of the filter cartridge; a tip is arranged at the bottom of the filter cartridge; a coaxial inner pipe is arranged inside the filter cartridge; a first barrel chamber is formed between the filter cartridge and the inner pipe; a coaxial vertical water pipe is arranged inside the inner pipe; a second barrel chamber is formed between the inner pipe and the vertical water pipe; a plurality of liquid dispersing holescommunicating the first barrel chamber with the second barrel chamber are formed in the side wall of the inner pipe; a circular box is arranged at the inner bottom of the second barrel chamber; a ring-shaped cover is arranged on the circular box; a circle of water inlet holes are formed in the surface of the ring-shaped cover; an inner hole of the ring-shaped cover is connected to the bottom endof the vertical water pipe; a floating ring-shaped cork sleeving the vertical water pipe is arranged on the ring-shaped cover. The agricultural soil remedying device increases the acting depth of a leacheate, reduces waste of the leacheate, and is high in soil treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an agricultural soil restoration device. Background technique [0002] At present, with the rapid development of the economy and the continuous growth of the population, the discharge of pollutants continues to increase, and the soil pollution continues to aggravate. Soil loss has become a worldwide problem and poses a serious threat to human existence. While realizing the concealment, seriousness and irreversibility of soil pollution, people also really realize that to do a good job in the protection of the atmosphere and water environment, we must also do a good job in the prevention and research of the soil environment. Soil leaching is an effective technical means to control soil pollution. Soil leaching generally uses soil accumulation leaching or column leaching, which is costly, and there are problems such as small leaching depth and waste of eluent. An agricult...

Soil leaching is an effective technical means to control soil pollution. Soil leaching generally uses soil accumulation leaching or column leaching, which is costly, and there are problems such as small leaching depth and waste of eluent.

An agricultural soil remediation device is disclosed in Patent No. CN201310420697.3, which includes an ozone generator, a multiphase gas-liquid mixing pump, a catalytic oxidation device and a water tank connected in sequence; it also includes a water inlet pipe, one end of which is connected to the The multi-phase gas-liquid mixing pump is connected, and the other end is connected with the water tank. The water inlet pipe is provided with a water inlet for connecting raw water; the bottom of the water tank is provided with a discharge port for discharging ozone water into the soil. However, this invention directly discharges ozone water into the soil surface, and the depth of action of ozone water is small, which easily causes waste of ozone water
