Description
Technical Field
The utility model belongs to the environmental protection field, concretely relates to be used for modularization soil drip washing equipment to improve screening structure.
Background
The soil pollution type mainly comprises heavy metal pollution such as cadmium, mercury, arsenic, copper, lead, chromium, zinc, nickel and the like. At present, solidification/stabilization technology is mostly applied to heavy metal contaminated soil engineering, but pollutants are not removed from the total amount, the long-term stability of the pollutants in the repaired soil cannot be guaranteed, and adverse factors such as difficult digestion of the repaired soil gradually restrict the wide application of the pollutants in the engineering. The soil leaching technology is to separate pollutants from soil by adding proper leaching agents through physical and chemical methods, so that permanent treatment of heavy metal polluted soil is realized. Compared with the prior art which applies a wide curing/stabilizing technology, the leaching technology has the advantages of pollution soil reduction, thorough pollution removal, multiple available ways of the repaired soil and the like, and is a repairing technology with wider application prospect in future engineering.
The soil leaching technology mainly depends on a set of complete leaching equipment in the field application of engineering, the equipment integrates a contaminated soil mixing and crushing system, a contaminated soil leaching system, a mud-water separation system and a water treatment system, and the equipment has the advantages of high treatment efficiency, equipment modularization, convenience in moving and the like.
Chinese patent CN 208131664U, entitled "an equipment for modular soil leaching", provides a device containing a soil screening device, a cleaning device, a grading screening device and a water treatment equipment. The device has the functions of leaching and screening, so that the space utilization rate is improved; the soil is separated according to the particle size while the soil is washed, and the resource utilization rate of the soil is improved. According to the patent device field operation condition that publication number is CN 208131664U, this equipment is high at feeding soil moisture content, and can cause the stifled storehouse of screening plant under the strong condition of soil property stickness, according to field analysis, mainly because this screening plant does not have driving system, in case feeding soil moisture content is high and the soil property is more under the condition of gluing, can lead to feeding soil to glue on the grid tray of slope arrangement in the screening plant, and then takes place stifled storehouse phenomenon. In the actual operation process of engineering, if meet the viscid soil that moisture content is higher than 20%, its current screening plant takes place stifled storehouse phenomenon easily, is difficult to will reach the effect of screening. The existing solution is that the screening device is shut down after blocking a bin and is manually removed, but the efficiency of washing the polluted soil is seriously reduced. In addition, the polluted soil to be leached and repaired is mostly from the former industrial production land, and the artificial activities of generating a large amount of construction wastes, such as field removal and even blasting, are frequently carried out before the polluted soil is excavated. Therefore, during the actual operation of the device disclosed in patent application No. CN 208131664U, the fed soil often contains a large amount of construction waste, which results in a blockage of the warehouse. This building rubbish screening storehouse is cylindrical netted stainless steel construction, and the cylinder diameter is 1000mm, and the mesh diameter is 40 mm. After the polluted soil passes through the construction waste screening bin, the construction waste with the diameter of more than 40mm is screened from the polluted soil, and the polluted soil with the diameter of less than 40mm enters a screening device in patent equipment with the publication number of CN 208131664U.

The utility model aims at solving the stifled storehouse trouble of screening plant that above-mentioned prior art's equipment often meets at the on-the-spot operation in-process to promote whole equipment contaminated soil drip washing efficiency. According to field analysis, the screening device of the equipment is frequently blocked for two reasons: 1. the water content of the fed soil is high, and the soil viscosity is strong; 2. building garbage which is difficult to break exists in the feeding soil, and a feeding bin is blocked.
The utility model discloses a concrete technical scheme as follows:
an improved screening device of modular soil leaching equipment is formed by connecting a closed crushing bin 1 and a building garbage screening bin 4, wherein the closed crushing bin 1 is in a steel-structure cylinder shape, the closed crushing bin 1 is horizontally placed, the inner side wall of the cylinder is a convex strip 3, and two motors 2 are arranged outside the cylinder to drive the closed crushing bin to rotate; the cylinder is driven to rotate rapidly by external power, and soil in the cylinder is broken and scattered by the convex strips 3 on the inner side wall of the cylinder; the construction waste screening bin 4 is a horizontally placed net-shaped stainless steel cylinder, and two motors are arranged outside the construction waste screening bin to drive the waste screening bin to rotate.
Further, the diameter of the cylinder of the closed crushing bin 1 is 1000mm, and the length of the cylinder is 30000 mm.
Furthermore, the maximum rotating speed of the closed crushing bin provided by the two motors 2 outside the cylinder is 22 revolutions per minute, and the rotating speed and the rotating direction can be adjusted according to the actual situation on site.
Furthermore, 10 steel structure convex strips 3 are uniformly distributed in the cylinder, and the size of the convex strips is 30000mm multiplied by 100 mm.
Further, the length of the building garbage screening bin cylinder is 20000mm, the diameter of the building garbage screening bin cylinder is 1000mm, and the diameter of the mesh is 40 mm.
Furthermore, the maximum rotating speed of the construction waste screening bin provided by the two motors outside the cylinder is 22 revolutions per minute, and the rotating speed and the rotating direction can be adjusted according to the actual situation on site.
