An integrated equipment for screening and crushing polluted soil and liquid dosing and mixing

Abstract

The invention discloses a polluted soil screening and crushing and liquid dosing and mixing integrated equipment, comprising: a support, a conveyor belt, a crushing mechanism, a screening mechanism, a material mixing mechanism, a mounting frame and a liquid medicine mixing mechanism; one end of the top side of the support is erected There is a conveyor belt, and a crushing mechanism is fixedly connected to the conveyor frame of the conveyor belt. The installation frame is installed on the other end of the top side of the bracket, the medicine preparation mechanism is installed on the top side of the installation frame, and the screening mechanism is installed on the installation frame. One end of the frame, the bottom side of one end of the mounting frame is equipped with a mixing mechanism, and the present invention can realize crushing, sieving, and mixing operations of soil by setting a crushing mechanism, a screening mechanism, a material mixing mechanism and a medicine preparation mechanism , It can continuously treat the soil, which is convenient for the treatment of polluted soil. Through the integrated equipment, the treatment efficiency is greatly improved, the polluted soil can be purified more quickly, and the soil environment can be better protected.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an integrated equipment for screening and crushing polluted soil and liquid dosing and mixing. Background technique [0002] Soil is an important part of the ecological environment. With the vigorous promotion of the government and environmentalists, the importance of soil pollution restoration has become increasingly prominent. Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Too many harmful substances, exceeding the self-purification capacity of the soil, will cause changes in the composition, structure and function of the soil, inhibit microbial activities, and gradually accumulate harmful substances or their decomposition products in the soil through "soil→plant→human body". Or it is indirectly absorbed by the human body through "soil → water → human body" to the extent that it endangers human health, which is ...

Problems solved by technology

[0003] The application publication number is CN104646406B, an integrated machine for remediation of heavy metal-contaminated soil. The invention integrates soil crushing, screening and rinsing, which not only saves labor, facilitates the operation of staff, but also can effectively repair heavy metal-contaminated soil. Although it can Realize integrated operation. During screening, because the waste residue generated by screening has nowhere to be discharged, it will cause blockage of the screen, and continuous operation cannot be carried out continuously and stably, which will delay the treatment efficiency of the soil;

[0004] The application publication number is CN109759213A, a crushing screen suitable for remediation of heavy metal-contaminated soil. In the present invention, there is a gap between the two crushing gears, the inlet is set directly above the gap, the turntable is set just below the gap, and the turntable is provided with A number of crushing rods; the connecting pipe connects the crushing chamber and the screening machine; the screening machine is equipped with a guide pipe and a plurality of screening grooves, and the screening groove includes a push plate, a screening chassis, a power unit and an end face, and the power unit is used for Push the push plate to move along the screening chassis. The screening chassis includes the upper screening net and the lower material receiving plate. The integrated crushing and screening machine of the present invention is suitable for the restoration of heavy metal contaminated soil. It has the advantage of high efficiency. In addition to the treatment of the soil, the supplement and mixing of the liquid medicine cannot be realized, and the soil supplement and improvement cannot be completed, and a better treatment effect cannot be achieved.

[0005] With the upgrading of urban industry and urban renewal, the soil remediation industry is booming, the number of remediation projects is increasing, and the types of pollution are complex. The development of the remediation industry has put forward higher requirements for remediation technology and equipment. At this stage, there is no fast and efficient solution for soil treatment. The integrated treatment device cannot realize continuous soil treatment of soil crushing, screening, dosing and mixing. Each operation process is a single process, and the continuity is not good, resulting in discontinuous treatment and requiring reciprocating loading and unloading. It consumes a lot of manpower and material resources, the processing efficiency is low, and the processing effect is not good
