Problems solved by technology

However, the existing radioactive soil treatment devices are relatively cumbersome, often fixed in a certain place, unable to move or difficult to migrate, and have no radioactive soil classification function, and cannot perform targeted and efficient decontamination treatment, making it difficult to deal with some sudden nuclear leaks

Embodiment Construction

[0020] Further illustrate the present invention below in conjunction with accompanying drawing.

[0021] Please refer to figure 1 ——As shown in 6, a mobile radioactive soil classification device is characterized in that the radioactive soil classification device includes a drying and screening device, an online detection device, a cleaning and drying device, a partition mechanism, a classification device, and a packaging device.

[0022] The drying and screening device (1) is realized by a feed inlet (8), a drying mechanism (9), and a soil vibration screening mechanism (11); the feed inlet (8) is placed on the top of the device for Put into the radioactive soil to be treated; the drying mechanism (9) is provided with hot air by the drying fan 1 (10) to dry the soil; the soil vibration screening mechanism (11) is placed below the drying mechanism, and the soil is passed through After the drying device (9) is dried, it enters the vibrating screening device (11) for screening, a...

Abstract

The invention discloses a movable sorting apparatus for radioactive soil. The movable sorting apparatus is characterized by comprising a drying and screening device, an online detecting device, a cleaning and drying device, a separator plate mechanism, a soil sorting device and a packaging device. The drying and screening device is used for drying soil and separating stone from soil. The on-line detecting device detects the radioactivity degree of soil and sends a command signal to the separator plate mechanism and the soil sorting device. The separator plate mechanism separates soil with different radioactivity degrees through four different separator plates. The soil sorting device uses four different funnels and corresponding containers for collecting and buffering soil, and then the containers full of soil are pushed onto a conveyor belt by rack push rods, then transported to the packaging device by the conveyor belt for packaging work and finally transported out by the conveyor belt. The movable sorting apparatus of the invention sorts soil according to the radioactivity degree of contaminated soil, and performs targeted treatment on soil with different radioactivity degrees,so treatment efficiency is greatly improved and treatment cost is effectively reduced. At the same time, the apparatus can be disassembled and assembled, and can be fixedly connected with a containerthrough the rack and then be transported to a desired place via the container, is applicable to emergency treatment of radioactive pollutants, and has the advantages of flexibility, convenience and great economic value and strategic significance.

Description

Technical field: [0001] The invention relates to the field of radioactive soil classification, in particular to a movable radioactive soil classification device. Background technique: [0002] In the "National Nuclear Safety and Radioactive Pollution Prevention and Control Plan", China has clearly proposed to "accelerate the decommissioning process of early reactors, nuclear fuel cycle facilities, scientific research facilities, and three-waste treatment facilities of key units, and complete a number of nuclear facility decommissioning projects" requirements. In the process of promoting this type of project, it is very important to solve the problem of radioactive contaminated soil due to various historical reasons such as leakage of military nuclear facilities, wrong discharge of waste liquid, and leakage of various cleaning water. Among them, the pollution of radioactive soil has the characteristics of strong concealment, great potential harm, and significant ecological i...
