The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1-2, the invention discloses an atmospheric pressure filter, which comprises a shell 2, wherein a filter plate 1 is arranged in the shell 2, the filter plate 1 divides the interior of the shell 2 into a slag storage cavity 21 and a clear liquid cavity 22, a flow divider 3 and a scraper 4 are also connected in the shell 2, the flow divider 3 comprises a liquid inlet 311 and a flow dividing port 321, the liquid inlet 311 is communicated with the flow dividing port 321, the flow dividing port 321 faces the filter plate 1, waste liquid flows in from the liquid inlet 311, flows out from the flow dividing port 321 and flows to the filter plate 1, and the flow dividing port 321 is used for dividing the liquid flowing out from the liquid inlet 311 so as to enable the liquid to flow to the filter plate 1 more uniformly; scraper 4 contacts and can slide along filter 1 with the surface of filter 1 to strike off the remaining impurity on filter 1 surface, prevent that filter 1 from blockking up.
It will be appreciated that the filter plate is a plate body provided with filter holes, which act to filter liquid flowing through the filter plate.
In one embodiment, the filter plate 1 is arranged obliquely.
In one embodiment, the flow divider 3 comprises a main tube 31, a flow dividing tube 32 is connected to the main tube 31, a liquid inlet 311 is disposed on the main tube 31, a flow dividing port 321 is disposed on the flow dividing tube 32, and the flow dividing port 321 extends from one side to the other side of the filter plate 1, so as to increase the contact area between the liquid flowing out from the flow dividing port 321 and the filter plate 1, improve the pressure uniformity and the filtration uniformity, and enhance the filtration effect and the utilization efficiency of the filter plate.
In one embodiment, as shown in fig. 4, the distribution opening 321 is rectangular to ensure a large contact area between the liquid flowing out from the distribution opening 321 and the filter plate 1.
Further, as shown in fig. 3-4, the shunt tube 32 is a rectangular tube. The shunt 32 can also be a round tube or other shaped tube.
In one embodiment, as shown in fig. 5, a sliding rail 6 is connected to the inner wall of the housing 2, the scraper 4 is connected to the sliding member 5, and the sliding member 5 is slidably connected to the sliding rail 6 to increase the sliding stability of the sliding member 5, so that the scraper 4 can be tightly attached to the filter plate 1 to ensure the effect of scraping off impurities. .
