Embodiment Construction

[0025] The present invention will be further described below in conjunction with the examples.

[0026] A maintenance-free filter is provided with a housing 1, an upper orifice plate 7 and a lower orifice plate 8 are arranged in the housing 1, a filter material 9 is arranged on the lower orifice plate, the filter material 9 adopts spherical particles, and the upper orifice plate 7 The diameter of the aperture and the aperture of the lower orifice plate 8 are smaller than the diameter of the filter material 9 to ensure that the filter material 9 will not be lost through the holes of the upper orifice plate 7 or the lower orifice plate 8. The filter material 9 adopts spherical particles that are more impact-resistant and not easily broken or Wear, also can adopt other shapes of small particles under the premise of ensuring that the external dimensions are not smaller than the apertures of the upper orifice plate 7 and the lower orifice plate 8 according to actual needs. The bott...

Abstract

The invention provides a maintenance-free filter which is provided with a shell, a backflushing opening is formed in the shell, a water inlet is formed in the upper portion of the shell, a water outlet is formed in the lower portion of the shell, an upper pore plate and a lower pore plate are arranged in the shell, a filter material is arranged on the lower pore plate, and the pore diameter of the upper pore plate and the pore diameter of the lower pore plate are both smaller than the boundary dimension of the filter material. And the upper part of the shell at the upper part of the upper pore plate is also provided with a drain outlet. The filter solves the technical problems that an existing filter is easy to block when being used for treating sewage containing impurities such as plush and fibers discharged in industries such as printing and dyeing, bathing and the like, the maintenance cost of the filter is higher, and the sewage treatment efficiency is influenced. The device and the method can be widely applied to treatment of sewage containing fine impurities.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a maintenance-free filter. Background technique [0002] In printing and dyeing, bathing and other industries, due to the large water consumption, in order to achieve sustainable development of environmental protection and energy saving, the discharged sewage needs to be treated and recycled. This kind of sewage contains more impurities such as fluff and fibers. The traditional filter treatment is easy to block, and the maintenance of the filter will consume a lot of manpower and material resources, and seriously affect the efficiency of sewage treatment. Contents of the invention [0003] The present invention aims at the technical problems that the existing filter is easy to block when treating the sewage containing impurities such as fluff and fibers discharged from printing and dyeing, bathing and other industries, the maintenance cost of the filter is high, and the technical p...
