The utility model discloses in through setting up a plurality of filter layers, the footpath grain of quartz sand reduces in proper order in the filter layer, can improve multi -media filter's filter effect, improves the sewage treatment quality.
Description
Technical field
The utility model relates to technical field of sewage, particularly relates to a kind of more medium filter.
Background technology
Medium filter (mediafilter) be media filtration system again, it is that one utilizes filter medium to remove each middle suspension, microorganism and other subparticles in water, finally reaches a kind of High-cfficiency Filtration equipment reducing water turbidity, the effect that purifies water.Conventional filtrate has quartz sand, activated carbon, anthracite, manganese sand etc.Extensively apply to the every profession and trades such as agricultural irrigation, chemical industry, oil, metallurgy.
Medium filter can use Single Medium, also can need to adopt medium according to difference.The filter of Single Medium is also shallow media filter, and its primary filtration media is generally quartz sand, granite and volcanic pisolite etc.Multilayer dielectricity filter is also profound medium filter, and its filter medium is made up of more than one filter mediums, general quartz sand, activated carbon, anthracite, manganese sand and other contact media.
In order to improve the filter effect of medium filter, be necessary to provide a kind of more medium filter.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of more medium filter exactly.
The utility model solves the technical scheme that its technical problem adopts:
A kind of more medium filter, described more medium filter comprises filtering ponds and is located at the water inlet at filtering ponds top, is positioned at the water-locator below water inlet, the exhaust outlet being positioned at water inlet side and the delivery port be positioned at bottom filtering ponds, described filtering ponds inside is provided with some filter courses, described filter course is quartz sand filtration layer, and in described different filter course, the footpath grain of quartz sand reduces from bottom to top successively.
As further improvement of the utility model, described filter course once comprises the first filter course, the second filter course, the 3rd filter course, the 4th filter course and the 5th filter course from bottom to top, and in described first filter course to the 5th filter course, the footpath grain of quartz sand reduces from bottom to top successively.
As further improvement of the utility model, in described first filter course, the footpath grain of quartz sand is 15 ~ 25mm, in second filter course, the footpath grain of quartz sand is 6 ~ 15mm, in 3rd filter course, the footpath grain of quartz sand is 4 ~ 6mm, in 4th filter course, the footpath grain of quartz sand is 2 ~ 4mm, and in the 5th filter course, the footpath grain of quartz sand is 0.5 ~ 0.53mm.
As further improvement of the utility model, described first filter course, the second filter course, the 3rd filter course are identical with the thickness of the 4th filter course, and the thickness of the 5th filter course is greater than the thickness of the 4th filter course.
As further improvement of the utility model, be provided with card below described filter course, below card, be provided with stay pipe.
The beneficial effects of the utility model are, by arranging multiple filter course in the utility model, in filter course, the footpath grain of quartz sand reduces successively, can improve the filter effect of more medium filter, improve quality of sewage disposal.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the schematic cross-section of more medium filter in the utility model one specific embodiment.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Shown in ginseng Fig. 1, the utility model discloses a kind of more medium filter, described more medium filter comprises filtering ponds 100 and is located at the water inlet 10 at filtering ponds top, is positioned at the water-locator 20 below water inlet, the exhaust outlet 30 being positioned at water inlet side and the delivery port 40 be positioned at bottom filtering ponds, described filtering ponds inside is provided with some filter courses, described filter course is quartz sand filtration layer, and in described different filter course, the footpath grain of quartz sand reduces from bottom to top successively.
Shown in ginseng Fig. 1, in the present embodiment, filter course once comprises the first filter course 61, second filter course 62, the 3rd filter course 63, the 4th filter course 64 and the 5th filter course 65 from bottom to top, and in described first filter course to the 5th filter course, the footpath grain of quartz sand reduces from bottom to top successively.And described first filter course 61, second filter course 62, the 3rd filter course 63 are identical with the thickness of the 4th filter course 64, the thickness of the 5th filter course 65 is greater than the thickness of the 4th filter course 64.
Preferably, in described first filter course 61, the footpath grain of quartz sand is 15 ~ 25mm, in second filter course 62, the footpath grain of quartz sand is 6 ~ 15mm, in 3rd filter course 63, the footpath grain of quartz sand is 4 ~ 6mm, in 4th filter course 64, the footpath grain of quartz sand is 2 ~ 4mm, and in the 5th filter course 65, the footpath grain of quartz sand is 0.5 ~ 0.53mm.
Further, in the present embodiment, below filter course, be provided with card 50, below card, be provided with stay pipe 51.
By arranging multiple filter course in the utility model, in filter course, the footpath grain of quartz sand reduces successively, can improve the filter effect of more medium filter, improves quality of sewage disposal.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
