Soil heavy metal pollutant dispensing device

Abstract

The invention provides a soil heavy metal pollutant dispensing device. A medicament spraying pipe is arranged in a walking device at the lower part of a chassis; a medicament tank comprises a medicament mixer shell; the medicament mixer shell is internally provided with a funnel and a stirring assembly; the funnel is internally provided with a nitrogen injection device; one end of a rotor rollingshaft in a spraying device sleeves the outer part of an inner end of a solution feeding pipeline and the other end of the rotor rolling shaft penetrates through the shell body and stretches into a spraying pipeline; the spraying pipeline is internally provided with a sprayer; the sprayer is internally provided with a medicament feeding adjusting knob; bell jars and a solid dispersion water body form a medicament falling channel; an annular medicament discharging pouring-out channel is formed between the adjacent bell jars; the rotor rolling shaft is internally provided with an impeller; an automatic rotation crusher is composed of a connecting section in the middle and spreading working sections at two sides; each spreading working section is provided with a crushing mechanism driven by amotor; a first-grade impeller, a second-grade impeller and an acceleration rotor pulling disc are arranged in a tail-end spraying nozzle, so that a solution can obtain acceleration in an accelerationchamber. The system has high working efficiency and a good medicament spraying work effect.

Description

technical field [0001] The invention belongs to the technical field of engineering treatment equipment, and in particular relates to a soil heavy metal pollutant spreading device. Background technique [0002] Some existing soil heavy metal pollutants need to be flattened first, then sprayed with chemicals for disinfection or sterilization, and then concentrated treatment can only be carried out after a period of drying. In the existing leveling treatment equipment for soil heavy metal pollutants, eccentric vibrating rollers are usually used to vibrate and crush the soil heavy metal pollutants at high speed, and cooperate with the other two leveling rollers to make the soil heavy metal pollutants broken However, in practice, the following shortcomings are often found. The rotation of the eccentric roller often rolls the heavy metal pollutants in the soil forward, so that the local accumulation is too high. Even after the heavy metal pollutants in the soil are dry, the surfac...

Problems solved by technology

In the existing leveling treatment equipment for soil heavy metal pollutants, eccentric vibrating rollers are usually used to vibrate and crush the soil heavy metal pollutants at high speed, and cooperate with the other two leveling rollers to make the soil heavy metal pollutants broken However, in practice, the following shortcomings are often found. The rotation of the eccentric roller often rolls the heavy metal pollutants in the soil forward, so that the local accumulation is too high. Even after the heavy metal pollutants in the soil are dry, the surface There are pits, which cannot meet the design requirements. In addition, the existing soil heavy metal pollutant treatment equipment is relatively large in size, and the steering process is laborious, inflexible, and low in efficiency, which needs to be improved urgently.

[0003] Under the current technical conditions, the leveling equipment technology has not yet matured, and the existing traditional processes and treatment methods still have the disadvantages of high processing costs and low leveling efficiency.

In addition, the spraying of chemicals in the prior art is carried out manually, which not only has low working efficiency, but also has unsatisfactory spraying effect.
