Filter with isolation structure

The utility model discloses a filter with an isolation structure, and relates to the field of filters, the filter comprises a moistureproof box body and a heat dissipation fan, the inner wall of the moistureproof box body is fixedly provided with a partition plate, the interior of the partition plate is embedded with an insulation net layer, and the interior of the moistureproof box body is movably provided with a bearing assembly; and a filter body is mounted on the inner surface of the bearing assembly through bolts. According to the filter with the isolation structure, the heat dissipation fan is arranged, so that the heat dissipation efficiency in the moisture-proof box body can be accelerated when the heat dissipation fan runs; therefore, the condition that the service life of the filter is irreversibly interfered due to the fact that the temperature in the isolation device gradually rises in the long-time operation process of the filter, and electric appliance elements in the filter are irreversibly dam
