Description
Technical field
Technical field of sewage is the utility model is related to, more particularly to a kind of sand filter of easy cleaning.
Background technology
Sand filter is the critical facility in sewage treatment project, for filtering out the bulky grain solid pollutant in sewage.It is existing
There is the sand filter in technology typically using the water inlet of sewage top, the form of cleaner liquid bottom water outlet.There is a defect in it, i.e., dirty
For water directly by sand body medium, sand body medium filters off the bulky grain thing in sewage, due to not carrying out coarse filtration to sewage, big
Grain impurity is blended directly in sand body medium, and long-term sand filter in the past is easy to fail, and filter effect declines, and changes sand body medium
Frequency it is too fast, so as to manpower and materials input cost increase.
Utility model content
The purpose of this utility model is the replacement frequency in view of the deficienciess of the prior art, i.e. sand body medium easily pollutes
It is too fast, so as to production cost it is too high, there is provided a kind of sand filter of easy cleaning.
In order to realize the purpose of above-mentioned utility model, technical solution adopted in the utility model：
A kind of sand filter of easy cleaning, including casing, described casing is interior to be filled with sand body medium, and the casing is connected with
Outlet pipe and blow-off pipe, the auger mechanism for crossing sand body medium is provided with the casing, and described auger mechanism includes horizontal stroke
Wear the auger shell of casing, offer some air-vents on the auger shell in the casing, the auger shell outside casing
Body one end is provided with water inlet pipe, and the other end is provided with the discharging opening of filtrate discharge auger shell.
During utility model works, sewage is first accessed into auger casing by water inlet pipe, auger casing is by the miscellaneous of bulky grain
Matter is filtered, and large granular impurity is rested in auger case body, and the sewage for filtering off impurity is entered in sand body medium by air-vent, sand
Body medium filter sewage again, the little particle impurity in sewage is filtered off, clean sewage is discharged from the outlet pipe of casing, works as sand
When the outlet pipe water in filter tank is smaller, auger mechanism is opened, auger mechanism is by the large granular impurity in auger shell from discharging opening
Discharge, so as to improve the effect of filter sewage.
In order that sewage oozes out above sand body medium, the effect of filter sewage is improved, the outlet pipe and casing
Top is connected, and described blow-off pipe is arranged on the bottom of casing.
In order to avoid sand body medium is discharged along sewage from outlet pipe, influence the filter effect of sewage, in the casing on
Portion is provided with the dividing plate for separating sand body medium, and the dividing plate, which is provided with, is easy to the filter opening that water oozed.
In order to improve speed of the sewage by dividing plate, while be easy to precipitate by the sand body medium of dividing plate, it is described every
Plate is in back taper, and the cone points to the bottom of casing.
For the ease of overhauling the sand filter, while the sand body medium being conveniently replaceable in casing, use is offered on the casing
In the manhole of maintenance, lower box offers sand removing hole.
Compared with prior art, the beneficial effects of the utility model are：Due to the presence of auger mechanism, auger shell can be with
First the large granular impurity in sewage is filtered, large granular impurity is rested in auger shell, it is a large amount of when assembling in auger shell
Impurity when, auger mechanism can be opened, auger mechanism discharges the large granular impurity assembled in auger shell, avoids manpower
Input, improve the filter effect of sewage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 casing, 101 sand body media, 102 outlet pipes, 103 blow-off pipes, 2 auger mechanisms, 201 auger shells, 202
Water inlet pipe, 203 discharging openings, 3 dividing plates, 301 filter openings, 4 manholes, 5 sand removing holes.
Embodiment
With reference to specific embodiment, the utility model is further described：
As described in Figure 1, a kind of sand filter of easy cleaning, including casing 1, casing 1 is interior to be filled with sand body medium 101, in order to
Avoid sand body medium 101 from being discharged along sewage from outlet pipe 102, influence the filter effect of sewage, the internal upper part of casing 1 is provided with sand
The dividing plate 3 that body medium 101 separates, dividing plate 3, which is provided with, is easy to the filter opening 301 that water oozed, in order to improve speed of the sewage by dividing plate 3
Rate, while be easy to precipitate by the sand body medium 101 of dividing plate 3, dividing plate 3 is in back taper, and cone points to the bottom of casing 1,
Casing 1 is connected with outlet pipe 102 and blow-off pipe 103, in order that sewage oozes out from the top of sand body medium 101, improves filtering
The effect of sewage, the top of outlet pipe 102 and casing 1 are connected, and blow-off pipe 103 is arranged on the bottom of casing 1, set on casing 1
There is an auger mechanism 2 for crossing sand body medium 101, auger mechanism 2 includes the auger shell 201 for crossing casing 1, the strand in casing 1
