Air filtering device

Abstract

The invention provides an air filtering device and belongs to the field of filtering equipment. The air filtering device comprises a filtering main body, a sealing device, an air guide pipe and a filter; the filtering main body is internally provided with a containing cavity; the containing cavity is internally provided with a separation plate; and the separation plate is used for dividing the containing cavity into a cleaning chamber and a filtering chamber located at the lower end of the cleaning chamber. The air filtering device is internally provided with the sealing device so that the sealing device can separate the filter from the cleaning chamber when high-pressure air is blown into the filter through the air guide pipe, and the high-pressure air moves in a direction opposite to a dust-containing air path; dust attached on the filter can be removed from the upper surface of the filter and dust accumulated in an air flow channel can be removed, so that the aim of regeneration of the filter is realized; the problems of an existing dust removing device are effectively solved and the regeneration efficiency of the filter is improved; the life cycle of the filter is prolonged; and compared with other pneumatic dust-removing filters, compressed air can be prevented from overflowing in a reverse blowing process and the use amount of the compressed air is reduced.

Description

technical field [0001] The invention relates to the field of filtering equipment, in particular to a gas filtering device. Background technique [0002] Gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, and urban water supply fields. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system, blast furnace water system in metallurgical industry, high pressure water descaling system for hot rolling. It is an advanced, efficient and easy-to-operate fully automatic filter device. [0003] The gas filter is composed of a shell, a multi-element filter element, a backwash mechanism, an electric control box, a reducer, an electric valve, and a differential pressure controller. The transverse partition in the shell divides the inner chamber into upper and lower chambers. The upper chamber is equipped with multiple filt...
