Description

Technical Field

[0001] The utility model relates to a filter turnover device, belonging to the technical field of air purification in nuclear power engineering. Background Art

[0002] During on-site maintenance of nuclear power plants and other nuclear facilities, and temporary field maintenance of nuclear power plants, it is inevitable that nuclear radiation will leak out, so a mobile device with satisfactory filtration efficiency is needed to purify local exhaust air on site. Due to the harsh on-site environment, the dust, radioactive aerosols and other substances generated are uneven, and the requirements for filters are relatively high.

[0003] After searching, a composite circular filter disclosed in the Chinese patent with announcement number CN206027259U has the following technical points: it includes a cylindrical filter element and a circular air inlet end cover and a disc-shaped outer blind end cover which are mounted at both ends and sealed by sealant. The characteristics are: the cylindrical filter element is composed of a primary filter element and a high-efficiency filter element, and is composed of an inner protective net, a primary filter element, a high-efficiency filter element, and an outer protective net from the inside to the outside; three support rods are arranged between the air inlet end cover and the outer blind end cover. This filter can filter radioactive aerosols and ordinary aerosols. The integrated structure of the circular primary and high-efficiency filter elements can greatly reduce the filter volume compared with the square filter under the same air volume; the airflow direction of axial air inlet and radial air outlet makes all pollutants gather inside the filter, reducing secondary pollution; the circular pre-filter element can increase its dust holding capacity and improve the service life of the filter, and after failure, it can be compressed and stored with a high compression ratio, reducing the amount of waste and saving disposal costs.

[0004] The filter shown in the above scheme requires manual operation when installing or disassembling it. However, in recent years, with the increase of retired low-level radioactive waste air filters, manual operation alone can no longer meet the actual needs of nuclear power plants, especially during the operation, low-level radioactive waste air filters often need to be clamped, grabbed, turned over, lifted, and transferred to workstations. Relying on manual labor to complete the above actions is not only labor-intensive and inefficient, but also easy to cause personal injury due to exposure to radioactive dust.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention
