Example 1

As shown in fig. 1-4, the liquid filtering anti-blocking dredging device comprises a filter cartridge 1, a slurry inlet 2 is arranged on one side of the upper part of the filter cartridge 1, an impurity outlet 4 is arranged at the bottom of the filter cartridge 1, and a bar type filter screen 5 is fixedly arranged inside the filter cartridge 1 along the vertical direction of the filter cartridge 1, wherein the bar type filter screen 5 is provided with a slurry inlet 3 on the filter cartridge 1 deviating from one side of the slurry inlet 2, the slurry containing impurities enters the inside of the filter cartridge 1 from the slurry inlet 2, after being filtered by the bar type filter screen 5, the impurities are discharged from the impurity outlet 4, and the slurry is collected by the slurry outlet 3.

Wherein, in order to avoid impurity to block up the sieve mesh of filter screen, insert between the adjacent mesh of strip filter screen 5 and be equipped with anti-blocking dredge, anti-blocking dredge is including inserting the slagging-off piece 6 of establishing between the filter mesh, and slagging-off piece 6 has push-and-pull connecting rod 8 through connecting rod round pin 7 fixed mounting, and push-and-pull connecting rod 8 top stretches out cartridge filter 1 top.

Preferably, the deslagging piece 6 is fixedly arranged on the deslagging plate 9, and the same push-pull connecting rod 8 is fixedly arranged on the front side and the rear side of the deslagging plate 9 through the connecting rod pins 7 respectively. Through controlling the same push-pull connecting rod 8 to move up and down, the deslagging plate 9 can be driven to move up and down, so that the deslagging sheets 6 are driven to move up and down, and impurities in the mesh holes are cleaned up.

The utility model discloses in, for the convenience of the reciprocating process of push-and-pull connecting rod 8, section of thick bamboo wall inboard still fixed mounting has slide rail 11 around cartridge filter 1, and the setting is slided on slide rail 11 in the 9 both sides of slagging-off board.

The utility model discloses in, slagging-off piece 6 sets up to triangle-shaped removes sediment piece 6, triangle-shaped's structure for remove the mesh inside that the most advanced one end of sediment piece 6 stretched into filter screen 5, can smash not hard enough impurity 10, make it become the tiny particle and fall, avoid blockking up.

In order to improve filtration efficiency, there are at least two sets of strip filter screens 5 at cartridge filter 1 inside fixed mounting, and every strip filter screen of group 5 corresponds and installs one and prevent stifled dredge, and the cartridge filter 1 bottom between two adjacent formula filter screens 5 all is provided with impurity export 4, and the sediment thick liquid passes through twice filtering action at least promptly, can effectively guarantee the clean of thick liquids, and the filter effect is better more thorough.
