a filtering device

Abstract

The invention relates to a filtering device, which comprises a shell, an inner cylinder and a filtering device arranged in the inner cylinder. There is a partition in the shell, the first cavity is formed below the partition, the second cavity is formed above, the inner cylinder and the filter device are arranged in the first cavity, and the first feeding material is provided on the side wall of the first cavity. The bottom end of the first cavity is provided with a first discharge port, the wall of the second cavity is provided with a second discharge port, the first feed port, the first discharge port and the second discharge port Both are equipped with valves; the inner cylinder is a cavity with openings at the upper and lower ends, and the filter device is installed in the cavity. The outer wall of the filter is opposite; the filter device includes a filter cartridge with a filter element in the circumferential direction and a chassis arranged at the bottom of the filter cartridge, and a channel communicating with the first cavity is arranged in the filter cartridge. It can effectively prevent the powder with small particles from being taken away by the wind, the powder collection rate is high, and it can improve the dust pollution in the working environment.

Description

technical field [0001] The invention relates to mechanical equipment in the chemical industry and shipbuilding industry, in particular to a filtering equipment. Background technique [0002] At present, in the process of industrial production, it is often necessary to collect powdery materials. The general operation is to use wind force to move the required dust in the air, and then separate the mixed airflow containing the powder from gas to solid, and collect the powder manually. Under the action of wind force, the powder with coarser particles falls into the collection vessel under the action of gravity, but the powder with finer particles fails to fall into the collection vessel in time and is taken away by the wind, resulting in a low powder collection rate, The operating environment is dusty and pollutes the environment, which is not conducive to the health of the staff. Contents of the invention [0003] The present invention aims to provide a filtering device, wh...
