Abstract
The utility model relates to a rotational flow medium filter. The rotational flow medium filter comprises a body, wherein a water inlet and a water outlet are formed in the body, a filtering layer is arranged in the body, the middle part of the body takes the shape of a direct cylinder, the bottom of the body is conical, the water inlet is tangent to the middle part of the body, the water outlet is arranged at the bottom of the body, the water outlet is communicated to the middle part of the body through a vertical water collecting pipe, the filtering layer is arranged in the middle part of the body and a gap of the bottom of the body, a plurality of annular water collecting through holes are formed in the radial direction of the water collecting pipe, water collecting branch pipes are arranged between the inner wall of the body and the water collecting pipe, and a plurality of water collecting holes are formed in the water collecting branch pipes. The rotational flow medium filter has the advantages that impurity accumulation is avoided due to the adopted structure working in two manners of forward filtration and reverse washing, so that the occurrence of filter material hardening, bacteria breeding and the like is retarded.
Description
Technical field
The utility model relates to a kind of filter, particularly a kind of eddy flow medium filter.
Background technology
Traditional sewage-treatment plant, generally include precipitation process and filtration treatment dual mode, wherein adopt the mode of precipitation process, owing to needing a plurality of facilities such as biochemical reaction tank and throwing in a large amount of chemicals, and can not be recycling, although can reach the purpose of purifying waste water, equipment is too complicated, cost is high, is difficult to carry out.
For the mode of filtration treatment, main defective is: the impurity after filtration easily stops up or hardens on filtration eyelet or filter, breed bacteria, and be difficult to clean.
The utility model content
The technical problems to be solved in the utility model is to overcome the above-mentioned deficiency of prior art, provide a kind of when can effectively filtering sewage impurity, easy cleaned eddy flow medium filter.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
a kind of eddy flow medium filter, comprise body, be provided with water inlet and delivery port on described body, described body interior is provided with filter course, the middle part of described body is straight-tube shape, the bottom of described body is cone-shaped, the middle part of described water inlet and body is tangent, described delivery port is arranged at the bottom of body, described delivery port is communicated to the middle part of body by the collector pipe of vertical setting, described filter course is arranged at the middle part of body, and in the gap of the bottom of body, the footpath of described collector pipe several annulars through hole that catchments that makes progress, be provided with the arm that catchments between the inwall of described body and collector pipe, be provided with several gully-holes on the described arm that catchments.
Adopt such structure, filtering under duty, when deriving after the sewage water filtration that namely needs to flow in water inlet, sewage enters in body from water inlet pipe, and under the cyclonic action that the tangent line water inlet produces, filter in filter course in the bottom cavity of the middle part of body and body, after the impurity in sewage was filtered layer interception and filters, clear water was collected by collector pipe and the through hole that catchments and is derived by the delivery port that is arranged at the body bottom.
Under the cleaning state, when namely needing the impurity in filter course is cleaned, inject clear water to the delivery port pressurization, at this moment, current carry out flush clean from catchment through hole ejection of the annular on collector pipe to the filter course in the bottom cavity of body, and the current of ejection form eddy flow in pyramidal body bottom, and gradually oppositely along flow into the filter course at the middle part of body from gully-hole, realize backward erosion, avoid impurity to pile up, thereby slow down the appearance of the situations such as filtrate hardens, breed bacteria.
Preferably, the top of described body is provided with the arc end socket.Adopt such structure, bonding strength is high, avoids occurring the phenomenon that stress is concentrated.
Preferably, be provided with air bleeding valve on described arc end socket.Adopt such structure, avoid inner and outer air pressure unbalance.
Preferably, the thickness of described filter course is 400mm～1000mm.
Compared with prior art, the beneficial effects of the utility model are: adopt the structure of forward filter, these two kinds of working methods of backward erosion, avoid impurity to pile up, thereby slow down the appearance of the situations such as filtrate hardens, breed bacteria.
