Problems solved by technology

[0007] However, since the treatment tank of a small sewage treatment site or a river drainage treatment site is small, there is no space for installing two dust collectors in one treatment tank, so it is necessary to separately set up the space for installing two dust collectors in the treatment tank. space, so there is a problem of increased equipment costs

Embodiment 1

[0025] Figure 1~ image 3 An embodiment of the coarse and fine dust dual-purpose grid-screen dust collector of the present invention is shown.

[0026] When carrying out sewage or drainage treatment at a sewage treatment site or a river drainage treatment site, in order to remove the garbage contained in the treated sewage or drainage, although there is no particular limitation, in this embodiment, for example, image 3 Screen dust collector A was used as shown.

[0027] The grid-type dust collector A is composed of a grid screen B and a rake C, and the grid screen B is arranged so as to block a part of the water flow channel D provided in the treatment tank, and the garbage in the water flow is captured and removed, so that The rake C is arranged so as to move up and down while meshing with the grid intervals of the grid screen B, and the rake C is used to comb and discharge the garbage (residue) caught by the grid screen B.

[0028] In addition, the grid B of this grid typ...

Abstract

The invention provides a grid-sifter dust remover for harsh grain or mote. Because of the grid-sifter dust remover mounted a in a processing pond, the thin grid-sifter with narrow grid space isn't damaged by the impact force of bulky rubbish, and the remover can simultaneously catch both bulky rubbish and mote. The grid-sifter dust removerhas a rake, which is up-down along the grid-sifter mountedin fluid course, collecting and discharging rubbish caught by the grid-sifter. Wherein the grid-sifter is made of the steel sifter bar with different board thickness according to the combined width of grid space, and the rake is made by combining grid-sifter for harsh grain and grid-sifter for mote and meshing the grid-sifter.

Description

technical field [0001] The present invention relates to a coarse particle and fine dust double-purpose grid-sieve type dust remover installed in treatment places and the like during sewage treatment and river drainage treatment, and particularly relates to such a coarse particle-fine dust double-purpose grid-screen type dust collector. The dust collector is a grid sieve formed by combining flat steels with different widths and thicknesses and adjoining them, so that coarse particles and fine dust contained in sewage or drainage can be dedusted simultaneously with one dust remover. Background technique [0002] In the prior art, in order to remove the garbage contained in the treated sewage or drainage when performing sewage or drainage treatment at a sewage treatment site or a river drainage treatment site, such a grid-screen dust collector is provided. The machine is composed of a grid screen and a rake. The above grid screen is arranged to block the flow channel in the tre...
