To achieve the above object, the utility model provides following technical solution：
A kind of sand filter for being conveniently replaceable filter material layer, including tank body, inlet channel, the outlet conduit being arranged on tank body,
It is arranged on several filter material layers of tank interior, which is characterized in that the side of the tank body corresponds to the position setting of each filter material layer
The opening that filter material layer is slipped into and skidded off is useful for, the circumference of filter material layer is provided with the baffle identical with the opening shape, each
The lower surface of filter material layer is provided with filter material layer fixed pedestal, and the filter material layer fixed pedestal is fixed in tank body.
Further, blow-down pipe is provided at the top of the tank body, blow valve is provided in the blow-down pipe.
Further, the opening is in outwardly open horn-like.
Further, it is provided with water proof rubber between the opening and baffle.
Further, the upper surface of the filter material layer fixed pedestal is provided with water proof rubber.
Further, it is provided with handle on the baffle.
Further, the filter material layer includes the anthracite coal measure, quartz sand layer and the garnet layer that set from top to bottom.
Compared with prior art, the beneficial effects of the utility model are：The filter material layer of the utility model is easily changed, and is being needed
When carrying out filter material layer flushing, by its fast quick-detach and spare filter material layer can be changed, by flushing process and normal filtering
Process is kept apart, and does not interfere the filtering being made into, on the whole for, accelerate the efficiency of filtering.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of sand filter for being conveniently replaceable filter material layer, including tank body 1, it is arranged on tank
Inlet channel 11, outlet conduit 12 on body 1, several filter material layers being arranged on inside tank body 1, in this present embodiment, filter material layer
There are three layers, wherein the filtrate of the small proportion of big grain size is distributed in upper strata, generally select anthracite, this anthracite there should be machinery by force
Degree is high, chemical stability is good, proportion is in the characteristics such as 1.4~1.6, and grain shape is preferably polyhedron；Proportion in middle grain size
Filtrate is distributed in centre, generally selects quartz sand, since the quartz sand of hand breaking has corner angle, than the mistake of natural siliceous sand
It is good to filter effect；The filtrate of the big proportion of small particle is distributed in lower floor, and generally may be selected as big proportion filtrate has garnet filtrate, magnet
Ore deposit filtrate, titanium ore or barite etc..The average grain diameter of i.e. three kinds filtrates from top to bottom, tapers into, and can make filter bed cuts dirty energy
Power is not fully exerted, so filter cycle is long, and due to one layer of particle diameter of filter medium very little of lowest part, thus for high concentrtion or
Turbidity fluctuation enters greatly water water source adaptability and strengthens, it is preferred that is followed successively by anthracite coal measure 2, quartz sand layer 3 and garnet from top to bottom
Layer 4.
In this present embodiment, the side of the tank body 1 corresponds to the position of each filter material layer and is provided with and is slipped into for filter material layer
And the opening skidded off, for the present embodiment by taking quartz sand layer 3 as an example, quartz sand layer 3 can slide in or out tank body 1, stone by opening 32
The circumference of sand layer 3 is provided with the baffle 33 identical with 32 shapes of the opening, when quartz sand layer 3 is slid completely into tank body 1, gear
Plate 33 blocks opening 32, and tank body 1 is made to form the entirety of closing.In order to strengthen its leakproofness, it is provided between opening 32 and baffle 33
Water proof rubber, the opening 32 is in outwardly open horn-like.Preferably, quartz sand layer accidentally slips out in order to prevent, on tank body 1
Rotatable pressing plate is additionally provided with, after quartz sand layer 3 is slid completely into tank body 1, pressing plate is gone on the outside of baffle, prevents its cunning
Go out.The lower surface of quartz sand layer 3 is provided with filter material layer fixed pedestal 31, for fixing quartz sand layer.It is it is noted that described
Filter material layer fixed pedestal 31 is fixed in tank body 1 and is integrally formed with tank body 1.Preferably, in order to further strengthen filter material layer with
The water proofing property of filter material layer fixed pedestal contact surface, the upper surface of the filter material layer fixed pedestal 31 are provided with water proof rubber.
Due to entirety of 1 inside of tank body for an opposing seal, the top of the tank body 1 is provided with blow-down pipe 5, described to put
Blow valve is provided in blank pipe 5, blow valve can be opened when necessary, destroys the leakproofness of tank body.
Incorporated by reference to Fig. 2, for the ease of sliding into and out for quartz sand layer 3, the shape of the baffle 33 is semi-circular, the gear
Handle 34 is provided on plate 33.
During normal filtration, blow valve is closed, and the valve in inlet and outlet pipes is opened；When replacement filtrate
During layer, the valve in inlet and outlet pipes is first closed, tank body 1 seals at this time, is unfavorable for skidding off for filter material layer, therefore again
Blow valve is opened, destroys air-tightness, then filter material layer is skidded off.After replacement, first close blow valve, then open inlet channel and
Valve on outlet conduit continues to filter.Compared with traditional backwash technique, the step of the utility model will backwash
It is detached with tank body, the influence of normal filtration will be preferably minimized, accelerate whole filter efficiency.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that by containing in the equivalent requirements of the claims is fallen
All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation
Involved claim.
