Description
Technical Field
The invention relates to the field of sewage treatment facilities, in particular to a sewage draining channel filter plate.
Background
In the field of sewage discharge, a sewage discharge channel is usually built, and multi-stage filtration is arranged in the sewage discharge channel, so that particle impurities in sewage are gradually filtered from coarse to fine; the simpler filtering device can directly adopt a filtering plate with filtering holes distributed on the surface, and the filtering holes of each stage of filtering plate are gradually reduced from the upstream to the downstream of the sewage draining channel so as to realize multi-stage filtration. In the long-term use process of the filter plate, the filter holes are blocked due to the accumulation of impurities, so that the filter plate needs to be cleaned at intervals; in the actual maintenance process, it is often difficult to directly see from the outside whether the filter plate has been clogged, and therefore the cleaning work is often performed when the filter plate is not clogged, resulting in a large amount of maintenance cost being wasted.
Disclosure of Invention
In view of the above problems, it is an object of the present invention to provide a filtering plate for a sewerage sewer, which allows a maintenance person to easily observe whether the filtering plate is clogged above the sewerage sewer, so as to perform a targeted cleaning operation, thereby saving maintenance costs.
The technical scheme adopted by the invention for solving the technical problems is as follows: the drainage channel filter plate comprises a main plate body inserted into a slot of a drainage channel, wherein filter holes are distributed on the surface of the main plate body, and the average pore diameter of the filter holes in one porous area on the main plate body is larger than that of the filter holes in other areas; the hole-shaped area is marked as a coarse hole area, and a thin pipe which extends upwards from the front of the coarse hole area to the upper part of the main plate body is further fixed on the main plate body; when the main board body is inserted into the sewage draining channel slot, the main board body is positioned above the water surface of the sewage draining channel, and the thin tube is positioned below the water surface.
Preferably, a cup mouth is formed at the upper end of the thin tube to form a flow guiding effect, so that water above the thin tube can flow into the thin tube more easily. Furthermore, a soft belt-shaped object is arranged in the cup mouth, floats on the water surface under the action of no water flow and is sucked into the thin tube under the action of water flow, so that whether water flow exists in the thin tube or not can be judged more easily.
Preferably, the average pore size of the filter pores in the coarse pore region is larger than that of the filter pores in the non-coarse pore region of the main plate body of the previous stage filter plate of the main plate body on which the coarse pore region is arranged; if the main board body where the coarse pore area is located does not have the upper stage filter plate, the average pore diameter of the filter pores in the coarse pore area is 1.5-2 times that of the filter pores in other areas; the area of the rough hole area accounts for 1% -3% of the area of the main plate body, so that the overall filtering efficiency of the main plate body is not affected obviously.
Preferably, the ratio of the average pore size of the coarse pore region to the average pore size of the other regions is a, and the number of pores per unit area of the coarse pore region is equal to the number of pores per unit area of the other regions; a flow gathering pipe extends forwards from the main board body near the coarse hole area, the area of an pipe orifice outside the flow gathering pipe is equal to the area of the coarse hole area, and the ratio of the area of the pipe orifice of the flow gathering pipe in contact with the main board body to the area of the coarse hole area is a2So as to ensure that the theoretical speed of the water flow flowing out of the coarse hole area is completely consistent with that of the water flow flowing out of the flow gathering pipe when the main plate body is not blocked; the outer pipe orifice of the flow gathering pipe is connected with an auxiliary pipe which extends upwards along the main board body, and the diameter and the pipe orifice height of the auxiliary pipe are consistent with those of the thin pipe; therefore, when the main plate body is not blocked, the water flow speed in the thick hole area and the flow gathering pipe is completely consistent, so that the negative pressure at the upper ends of the thin pipe and the auxiliary pipe is completely equal, and the water body liquid level between the thin pipe and the auxiliary pipe smoothly flows forwards without being deviated to any one of the thin pipe and the auxiliary pipe.
The invention has the beneficial effects that: when the pollution discharge channel filter plate is used, if the main plate body is not obviously blocked, the water flow speed passing through the thick hole area is closer to the water flow speed passing through other areas, and the upper end and the lower end of the thin tube have no obvious water flow difference, so that the negative pressure at the upper end of the thin tube is not enough to suck the water flow near the upper end of the thin tube into the thin tube; and when the mainboard body obviously blockked up, then because the tubule lower extreme is the coarse pore district, this regional rivers forward velocity will be far greater than the tubule upper end (tubule upper end rivers forward velocity is zero basically), thereby make the tubule upper end produce obvious negative pressure, in order to inhale the tubule with the water of tubule upper end, thereby produce the rivers trace on the surface of water of tubule upper end, obviously to the tubule migration from all directions if surface of water impurity, thereby can judge, the main filtering part of this mainboard body has obviously blockked up, can carry out pertinence clearance by maintainer.

The first embodiment is as follows:
in the first embodiment shown in fig. 1 and 2, the sewer filtering plate comprises a main plate body 2 inserted into a slot 1 of a sewer, wherein the surface of the main plate body 2 is full of filtering holes, and the average pore diameter of the filtering holes in one porous area on the main plate body 2 is larger than that of the filtering holes in other areas; the hole-shaped area is marked as a thick hole area 20, and a thin tube 3 which extends upwards from the front of the thick hole area 20 to the upper part of the main plate body is also fixed on the main plate body 2; when the main plate body 2 is inserted into the sewage draining channel slot 1, the upper edge of the main plate body 2 is positioned above the water surface of the sewage draining channel, and the upper end of the thin tube 3 is positioned below the water surface.
In the first embodiment, a cup mouth 31 is formed at the upper end of the thin tube 3 to form a flow guiding effect, so that the water above the thin tube 3 can more easily flow into the thin tube 3. Further, a soft strip (not shown) may be provided in the cup mouth 31, and the soft strip floats on the water surface when no water flow is applied, and is sucked into the narrow tube 3 when a water flow is applied, so that it is easier to determine whether or not a water flow is present in the narrow tube 3.
In the filter plate, the average pore diameter of the filter pores in the coarse pore region 20 is larger than that of the filter pores in the non-coarse pore region of the main plate body of the upper stage filter plate of the main plate body 2 where the coarse pore region is located; thereby ensuring that the water body filtered by the upper stage filter plate can not block the coarse hole area 20 of the filter plate of the present stage; if the main board body where the coarse pore area 20 is located does not have a previous stage filter plate, the average pore diameter of the filter pores in the coarse pore area 10 is 1.5-2 times that of the filter pores in other areas; the area of the rough hole area 20 accounts for 1% -3% of the area of the main plate body 2, so that the overall filtering efficiency of the main plate body 2 is not affected significantly.
When the pollution discharge channel filter plate is used, if the main plate body 2 is not obviously blocked, the water flow speed passing through the coarse hole area 20 is closer to the water flow speed passing through other areas, and the upper end and the lower end of the thin tube 3 have no obvious water flow difference, so that the negative pressure at the upper end of the thin tube 3 is not enough to suck the water flow near the upper end of the thin tube into the thin tube; and when the mainboard body 2 obviously blockked up, then because the 3 lower extremes of tubule is coarse hole district 20, this regional rivers forward velocity will be far greater than tubule 3 upper end (tubule upper end rivers forward velocity is zero basically), thereby make the tubule upper end produce obvious negative pressure, in order to inhale tubule 3 with the water of tubule upper end, thereby produce the rivers trace on the surface of water of tubule upper end, obviously to tubule 3 migration from all directions if surface of water impurity, thereby can judge, this mainboard body 2's main filtering part has obviously blockked up, can carry out pertinence clearance by maintainer.
Example two:
for the second embodiment shown in fig. 3, different from the first embodiment, it is noted that the ratio of the average pore size of the coarse pore region 20 to the average pore size of the other regions is a, and the number of pores in the coarse pore region per unit area is equal to the number of pores in the other regions per unit area; a flow-collecting pipe 40 is also extended from the main plate body 2 in the vicinity of the wide hole area 20, and the flow-collecting pipeThe area of the outer nozzle of the flow gathering pipe 40 is equal to the area of the coarse hole area 20, and the ratio of the area of the nozzle of the flow gathering pipe 40 contacting with the main plate body 2 to the area of the coarse hole area 20 is a2So as to ensure that the theoretical speed of the water flow flowing out from the wide-hole area 20 and the water flow flowing out from the flow gathering pipe 40 are completely consistent when the main plate body 2 is not blocked; the outer pipe orifice of the flow gathering pipe 40 is connected with an auxiliary pipe 4 extending upwards along the main plate body 2, the diameter and the pipe orifice height of the auxiliary pipe 4 are consistent with those of the thin pipe 3, and a cup mouth 41 is also formed at the upper end of the auxiliary pipe 4; thus, when the main plate body 2 is not clogged, the water flow velocity in the wide hole region 20 and the flow rate in the flow concentration pipe 40 are completely matched, so that the negative pressures at the upper ends of the narrow pipe 3 and the sub pipe 4 are completely equalized, and the water surface between them smoothly flows forward without being biased to either the narrow pipe 3 or the sub pipe 4.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
