Document Type and Number:
WIPO Patent Application WO/2019/006718
Kind Code:
A1
Abstract:
Disclosed is a filter device with an inverted filter screen and for a water pump inlet of a garbage incineration power plant. The filter device comprises a filter container (1A) and a filter screen (2) arranged inside the filter container (1A), wherein the filter container (1A) and the filter screen (2) are of a barrel-shaped structure; a water inlet (1A1) of the filter container (1A) is arranged at a lower side, whereas a water outlet (1A2) thereof is arranged at an upper side; a barrel bottom (2B) of the filter screen (2) faces upward, whereas a barrel mouth (2A) thereof faces downward, thereby being in an inverted state, and a ferromagnetic body (3B) is further arranged on the barrel bottom (2B) of the filter screen (2); and an electromagnet (3A) is further arranged on a cover plate (1B) of the filter container (1A). When the electromagnet (3A) is conducted, the ferromagnetic body (3B) is attracted so as to drive the filter screen (2) to move upward, when the electromagnet (3A) is not conducted, the filter screen (2) moves downward under the action of its own gravity, and when the filter screen (2) moves upward and downward, sludge absorbed to the filter screen (2) falls down. The bottom of the filter container (1A) is of a funnel-shaped structure, the bottom of the filter container (1A) is further provided with a sludge discharge pipe (4), the sludge discharge pipe (4) is provided with a valve (4A), and the sludge falling down from the filter screen (2) is discharged via the sludge discharge pipe (4). The filter screen (2) can be cleaned without needing to stop a pump, which not only saves on manpower, but also improves the working efficiency.
