Crank type soil crushing and mixing device for heterotopic soil remediation and treatment

Abstract

The invention discloses a crank type soil crushing and mixing device for heterotopic soil remediation and treatment, wherein the crank type soil crushing and mixing device comprises a support base; anextrusion box is arranged at the upper end of the support base, extrusion plates are arranged on both sides of the interior of the extrusion box, and a drainage cavity is arranged on the inner side of each of the extrusion plates; agent spray nozzles and extrusion teeth are arranged on the inner side of each drainage cavity uniformly at intervals; piston rods are arranged outside the extrusion plates; a piston plate is connected on the outer side of each piston rod; an agent leading cylinder is arranged on the outer side of each piston plate; a crushing box is arranged in the middle of the upper end of the extrusion box, crushing shafts are arranged in the upper end of the crushing box, the right ends of the crushing shafts are meshed with each other through a straight gear group, the right ends of the crushing shafts at the front end are connected with bevel gear groups, and the lower end of each bevel gear group is connected with a rotating shaft; the middle of the lower end of eachrotating shaft is provided with a crank; the middle of each crank is provided with a sliding sleeve; the inner side of each sliding sleeve is hinged with a connecting rod. According to the crank typesoil crushing and mixing device, soil is subjected to primary crushing mixing, at the same time, the soil is extruded again by the extrusion plates in the extrusion box, real-time automatic dosing and mixing effect is achieved, and the mixing effect of a remediation agent and the soil is increased.

Description

technical field [0001] The invention relates to the technical field of soil treatment equipment, in particular to a crank type soil crushing and mixing device for ectopic soil restoration and treatment. Background technique [0002] At present, the overall situation of soil pollution in my country is grim, and soil pollution is serious in some areas. Heavy soil pollution areas and high-risk areas have appeared in heavily polluted enterprises or industrial-intensive areas, industrial and mining mining areas and surrounding areas, urban and suburban areas. There are various types of soil pollution, showing the coexistence of new and old pollutants, and the combination of inorganic and organic pollution. There are many ways of soil pollution, the reasons are complicated, and the control is difficult. Soil pollution has become an important factor affecting people's health and social stability. [0003] Contaminated soil needs to be treated with soil remediation technology to e...

Problems solved by technology

[0004] At present, some ectopic polluted soil remediation often adopts single-machine crushing, single-machine mixing, and manual dosing in the process of crushing and mixing, without forming a unified automation system, so more manpower and material resources are invested. In addition, due to chemical and pollution Uneven soil mixing may lead to problems such as low restoration efficiency. At the same time, separate operations may require more secondary pollution protection measures. Therefore, we need to design an integrated soil crushing and mixing device
