Self-flushing and self-blowing water-gas two-purpose rotational flow filter

Abstract

The invention belongs to the field of water and gas treatment devices and particularly relates to a self-flushing and self-blowing water-gas two-purpose rotational flow filter, which is used for circulating water and gas treatment for factories of steel smelting, iron smelting, steel rolling and sintering and the like of a metallurgical enterprise, and is also used for the circulating water and gas treatment for industries of buildings, mining, electric power and the like. The self-flushing and self-blowing water-gas two-purpose rotational flow filter comprises a cylinder body comprising three parts including a separating filtering cavity, a water drainage cavity and a dirt storage cavity; the separating filtering cavity is provided with an inlet pipe; the water drainage cavity is provided with an outlet pipe; the lower part of the dirt storage cavity is provided with a dirt discharge valve; and an inverted-conical filtering net is arranged between the separating filtering cavity and the water drainage cavity. The self-flushing and self-blowing water-gas two-purpose rotational flow filter has the characteristics of being simple in structure, reasonable in design, strong in adaptability, not easy to be plugged, reliable in running, and simple and convenient to maintain.

Description

technical field [0001] The invention belongs to the field of water and gas treatment equipment, that is, a self-washing, self-blowing, water and gas dual-purpose cyclone filter. It is used for circulating water and gas treatment in metallurgical enterprises such as steelmaking, ironmaking, coking, steel rolling and sintering plants, and also for circulating water and gas treatment in construction, mining, electric power and other industries. Background technique [0002] In the prior art, the application of cyclone filter (water purification device) is rising at home and abroad. It is a preliminary filter device that does not require external power and is widely used in industrial water, agricultural water and domestic water. The traditional cyclone filter consists of a cylinder, which consists of a separation filter cavity and a drainage cavity. The separation filter cavity has an inlet, and the drainage cavity has an outlet. There is a drain valve at the lower part of the ...

AI Technical Summary

Problems solved by technology

The traditional cyclone filter consists of a cylinder, which consists of a separation filter cavity and a drainage cavity. The separation filter cavity has an inlet, and the drainage cavity has an outlet. There is a drain valve at the lower part of the separation filter cavity. The disadvantages of the plate filter are: 1. The mesh of the straight-through filter basket is blocked by impurities in a short period of time, reducing the water flow and affecting the water supply effect

2. Frequent disassembly and removal of the filter screen for cleaning and washing is required, which increases the labor intensity of the operators and wastes manpower and material resources (once a day)

3. There is no space for dirt storage in the cylinder
