Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail so that advantages of the present invention and
Feature can be easier to be readily appreciated by one skilled in the art, thus makes protection scope of the present invention apparent
Clear and definite defines.
Refering to shown in Fig. 1-2, the economizer filtering foreign system of the present invention, including ash bucket 1 and storehouse pump 2, its
Also include:
Ash discharging pipe 3, is used for connecting ash bucket 1 and storehouse pump 2, and ash discharging pipe 3 is provided with Rose Box 4；
Slide unit 5, is arranged on the bottom of Rose Box 4；
Filter 6, is arranged on the upper surface of slide unit 5, and is slidably connected with slide unit 5, wherein, and filter 6
Bottom middle position be provided with drainage screen 7.
Power source 8, is arranged on the side sidewall of Rose Box 4, is used for driving filter 6 along slide unit 5 level
Mobile, wherein, filter 6 has initial position and strain position, when filter 6 is in initial position,
Filter 6 staggers completely with ash discharging pipe 3, when filter 6 is in strain position, and drainage screen 7 and lower ash
The position of pipe 3 is corresponding.In the present embodiment, in order to ensure that filter 6, when strain position, can have
Good filter efficiency, the cross-sectional area of drainage screen 7 is more than the cross-sectional area of ash discharging pipe 3.
The present invention is during normal defeated ash, and power source 8 drives filter 6 to be moved horizontally to along slide unit 5
Initial position, filter 6 staggers completely with ash discharging pipe 3, and it does not produce any impact to the operation of normal defeated ash,
And when boiler maintenance, power source 8 drives filter 6 to be moved horizontally to strain position along slide unit 5, maintenance
Foreign material enter into the filtration after ash discharging pipe 3 through drainage screen 7, and foreign material are trapped on drainage screen 7, and ash returns automatically
