Abstract
An inclined screen-type filter comprises a filter box body and a filter screen mounted in the box body, wherein a water inlet and a water outlet are formed on the box body; an overflowing cavity is arranged in the box body; the water inlet is positioned at the top of the overflowing cavity; an overflowing opening lower than the water inlet is formed at the upper part of the overflowing cavity; the filter screen is obliquely coupled below the overflowing opening; a purified water cavity used for accommodating filtered purified water is formed among the filter screen, the overflowing cavity and the box body; and the water outlet is positioned on the side wall of the purified water cavity. The design of the utility model is ingenious, the filter screen is obliquely arranged, when water flows through the surface of the filter screen, most water enters the purified water cavity through the filter screen, and impurities filtered out by the filter screen and a very small amount of water flow into an impurity holding tank under the filter screen along the surface of the filter screen. By adopting the structural design, impurities isolated on the filter screen can be washed into the impurity holding tank timely, so as to prevent the impurities from accumulating on the filter screen and blocking the filter screen.
Description
Technical field
The utility model belongs to water-treatment technology field, specifically a kind of slanted screen formula filter.
Background technology
In purificating raw water and sewage disposal technology, filtering physics impurity generally adopts sieves to filter, common sieves is for being densely covered with the aperture grid, and orifice size is less than physics contaminant size to be filtered, when current can fall the physics contaminant filter during by aperture.When sieves is installed, generally also be that vertical water flows through the filter direction, promptly current are vertically by the sieves plane, and the sieves of this form generally exists in long-time filtration and stops up aperture afterwards because the physics impurities accumulation is more easily, cause current not smooth, influence filter efficiency and filter effect.
The utility model content
The technical problems to be solved in the utility model provides a kind of not susceptible to plugging slanted screen formula filter.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of slanted screen formula filter, comprise a filter box-body and be installed on the interior sieves of casing, casing is provided with water inlet and delivery port, in casing, also be provided with a spill cavity, water inlet is positioned at the spill cavity top, is provided with the overfall that the position is lower than water inlet on spill cavity top, and sieves tilts to be undertaken in the overfall below, be formed between sieves and spill cavity and the casing holding the water-purifying cavity that filters the back water purification, delivery port is positioned at the water-purifying cavity sidewall.
Collect the impurity that filters for convenience, below, sieves lower edge is provided with the impurity that holds impurity screening and holds groove.
As the optimization to such scheme, described sieves is symmetrical distribution with the spill cavity.Can be vertical section as casing is trapezoidal stage body.
The utility model design is ingenious, sieves is obliquely installed, when water flows through the sieves surface, most of water enters in the water-purifying cavity by sieves, hold in the groove by sieves impurity that filters out and few part water flows to the below along the sieves surface impurity, this structural design can be in time washed to impurity and is held in the groove being isolated in impurity on the sieves, prevents from that impurity from accumulating to stop up sieves on sieves.
Description of drawings
Accompanying drawing 2 is a present embodiment stereoscopic-state structural representation.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in drawings, present embodiment proposes is a kind of design science, can effectively prevent the slanted screen formula filter that sieves stops up, this filter comprises casing 1 and the sieves 2, spill cavity 13, water-purifying cavity 15, the impurity that are arranged in the casing 1 hold groove 16, wherein, be provided with water inlet 11 at spill cavity 13 tops, be provided with delivery port 12 at water-purifying cavity 15 sidewalls.
After water to be filtered overflows from overfall 14, along sieves 2 to dirty, most water flow in the water-purifying cavity 15 by sieves 2 in the flow process, are arranged in impurity that sieves 2 tops filter out and fraction water and then flow to impurity along sieves 2 upper surfaces and hold groove 16 and put together.As can be seen, this sieves that is obliquely installed 2 can guarantee that impurity can not rest on sieves 2 surfaces and stop up sieves 2, has avoided because the clogging that causes after sieves 2 long-time the uses.
More than be the preferred version of embodiment for the utility model realization; and it is non-limiting exhaustive; the utility model can also have other variations under same idea; need to prove; under the prerequisite that does not break away from the present utility model design, any conspicuous replacement is all within the utility model protection domain.
