Abstract
The utility model discloses a multi-medium filter comprising a tank body, consisting of a cylindrical barrel, an upper sealing head and a lower sealing head; the upper sealing head is provided with a water inlet and a water intake pipe system; the lower part of the lower sealing head is provided with a water outlet and a water draining pipe system; the tank body is internally provided with a porous plate; the porous plate is provided with a filter cap and a filter material layer, wherein the porous plate is of an arched structure. As the preferable scheme of the structure, the ratio of the arch height of the porous plate and the diameter of the porous plate is 1/10 to 1/4. As the further improvement of the above scheme, the ratio of the arch height of the porous plate and the diameter of the porous plate is 1/5. With adoption of the arched structure and on the condition of the unchanged weights of the filter cap and the filter material layer, the porous plate compared with the flat plate structure has reduced thickness and keeps constant rigidity, so that the multi-medium filter has the characteristics of material conservation, low cost and good rigidity.
Description
Technical field
The utility model belongs to the water treatment facilities technical field, relates in particular to a kind of suspended particles that are used for separating or hold back water into, reduces the filter of suspended impurity content in the water inlet.
Background technology
At present water treatment system generally uses filtering material filter to filter equipment as preliminary treatment, is used for separating or holds back the into suspended particles of water, and the filter tank body is made up of the cylindrical tube and the upper and lower end socket of upright setting; Upper cover is provided with water inlet and water inlet piping; The low head bottom is provided with delivery port and discharge piping, and the porous plate in the tank body is provided with the filter cap installing hole, and a plurality of filter caps are installed; Filter cap is provided with narrow annular channel, and the gap of slit is 0.2～0.5mm; Porous plate top is quartz sand, ANTHRACITE FILTER MEDIA layer, and former water is sprayed into through water-distribution nozzle by the water inlet of tank body top, gets into filter material layer and obtains filtering, and the clear water after the filtration is flowed out by the delivery port that the tank body below is provided with, and realizes filter process.Dirt of holding back when filtering layer and impurities accumulation through gauge measurement filtering layer pressure reduction up and down, when pressure reduction is increased to certain numerical value, stop to filter to a certain degree the time, adopt the method for backwash (washing, air purge) to make media regeneration.Porous plate is slab construction, and in order to carry the weight of filter cap, filter material layer, porous plate needs enough thickness, otherwise during normal use can be out of shape inadequately because of rigidity.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of and saves that material, expense are low, the more medium filter of good rigidity.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of more medium filter; Comprise the tank body that cylindrical tube and upper cover, low head are formed; Upper cover is provided with water inlet and water inlet piping, and the low head bottom is provided with delivery port and discharge piping, is provided with porous plate in the tank body; Porous plate is provided with filter cap and filter material layer, it is characterized in that: described porous plate is domes.
As the preferred version of said structure, the sagitta of the described porous plate of the utility model and porous plate diameter ratio are 1/10～1/4.
As the further improvement of such scheme, the sagitta of described porous plate and porous plate diameter ratio are 1/5.
The porous plate of the utility model adopts domes, under the constant situation of the weight of filter cap, filter material layer, can reduce thickness and keep rigidity constant than the porous plate of slab construction, saves material, low, the good rigidity of expense.
