Abstract
The invention discloses a domestic wastewater filter. The domestic wastewater filter is provided with a housing body; the housing body is connected with a wastewater inlet pipe in a tangential direction; the upper part of the housing body is connected with a wastewater outlet pipe; the lower part of the housing body is connected with a lower discharge pipe; an upper conical filter screen barrel is assembled in the upper part of an inner cavity of the housing body, and a lower conical filter screen barrel is assembled in the lower part of the inner cavity of the housing body; the upper conical filter screen barrel and the lower conical filter screen barrel are communicated; a separating plate used for separating the upper part and the lower part of the inner cavity is arranged on an outer annular cavity of the upper conical filter screen barrel and the lower conical filter screen barrel; and the bottom of the lower conical filter screen barrel is connected with an upper discharge pipe. The domestic wastewater filter possesses following advantages: the domestic wastewater filter possesses three-stage filtering function and two-stage backwashing discharging function; impurity pollutants in filter barrel screens can be removed effectively; pollutant removing efficiency is high; resistance force is small; double backwashing is realized; and wastewater treatment amount is large.
Description
Technical field
The invention belongs to a kind of sewage dirt device for filtering impurities, particularly one way of life effluent filter.
Background technology
Sanitary sewage again with in need to filter out dirt impurity, domestic at present used mostly be single-stage tubular type filter screen, little by fluid media (medium) area, resistance is big, it is impossible to effectively prevents diameter >=3mm granule from removing, affects the utilization to sewage of the next stage technique.And need manually to remove dirt, impurity during existing filter maintenance, make maintenance cost be greatly increased.
Summary of the invention
It is an object of the invention to provide one way of life effluent filter, not only there are three grades of formula filtering functions but also there is the dirt eliminating function carrying out two grades of backwashes, can effectively remove sanitary sewage impurity dirt, be beneficial to sewage again with.This filter ultrahigh in efficiency, resistance is little, dual backwash, and blowdown is convenient.
It is an object of the invention to be achieved through the following technical solutions: it arranges housing, tangentially connected water inlet pipe on housing, outlet pipe is connected at housing upper, down blow pipe is connected in lower housing portion, it is characterized in that: the upper group at housing cavity loads onto conical filter net bucket, lower set loads conical filter net bucket, and upper and lower conical filter net bucket connects, arranging, at the outside ring cavity of upper and lower conical filter net bucket, the dividing plate cutting off upper and lower two chambeies, the bottom of inferior pyramidal drainage screen bucket connects upper blow-off pipe.
The invention have the advantage that the function with three-stage filtration, but also there is the dirt eliminating function of two grades of backwashes, effectively disposed the impurity dirt in sanitary sewage, it is ensured that sewage again with time requirement to water quality.Scrubbing efficiency is high, and resistance is little, dual backwash, and blowdown is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation (sectional view) of the present invention
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
See Fig. 1,2, there is structure as follows: tangentially connected water inlet pipe 1 on housing 4, on the top of housing 4 by Flange joint upper cover, upper cover connects outlet pipe 2, down blow pipe 10 is connected in housing 4 lower end, being positioned on the tube wall of housing at down blow pipe 10 and arrange mudhole, upper end assembles pollution discharge cover 8.Upper group at housing 4 loads onto conical filter net bucket 3, and lower set loads conical filter net bucket 6, and upper conical drainage screen bucket 3 is multilamellar stainless steel cloth, and inferior pyramidal drainage screen bucket 6 is rustless steel punched-plate.Upper and lower conical filter net barrel cavity phase siphunculus.Arranging, at the outside ring cavity of upper and lower conical filter net bucket, the dividing plate 5 cutting off upper and lower two chambeies, the bottom of inferior pyramidal drainage screen bucket 6 connects upper blow-off pipe 7.In the side of housing 4, inspection socket 11 is set.
Operation principle: carry out primary filter along rotation direction by the rotating fluid medium of tangential water inlet pipe 1 housing 4, then medium carries out cascade filtration along direction of rotation entrance inferior pyramidal drainage screen bucket 6, rises and carry out three-stage filtration at the upper conical drainage screen bucket 3 through the fine stainless (steel) wire of multilamellar in conical filter net bucket.The float less than 3mm particle diameter through inferior pyramidal drainage screen bucket 6 is made again to be able to fine filtering.After the fine filtering of above-mentioned chimney filter, the solid matter of the Φ >=0.1mm in medium and the float of Φ >=0.2mm are absent from, blow-off pipe 10 periodical blowdown that the dirt separated through one-level, cascade filtration will have under pollution discharge cover.On the dirt footpath that upper conical drainage screen bucket 3 filters, comb 7 is discharged.Simultaneously, down blow pipe 10 and upper blow-off pipe 7 also carry inferior pyramidal drainage screen bucket 6 and the backwash function of upper conical drainage screen bucket 3 respectively, during backwash, first close the valve on water inlet pipe 1 path, then opening down blow pipe 10 valve, inferior pyramidal drainage screen bucket 6 and the backwash of upper conical drainage screen bucket 3 can be completed.Before and after three grades of formula filters the difference of Pressure gauge more than, when 0.02NPa and backwash are also inoperative, it was shown that the blocking of mesh is quite serious.Now should open upper cover, upper and lower chimney filter is overhauled.Maintenance can also be decided whether through inspection socket 11 after observing.
Claims (1)
1. a heating air conditioning sanitary sewage filter, it arranges housing, tangentially connected sewage water inlet pipe on housing, sewage outlet pipe is connected at housing upper, down blow pipe is connected in lower housing portion, it is characterized in that: the upper group at housing cavity loads onto conical filter net bucket, bottom inferior pyramidal drainage screen bucket, on, inferior pyramidal drainage screen bucket connects, upper, the outside ring cavity of inferior pyramidal drainage screen bucket arranges on partition, the dividing plate in lower two chambeies, the bottom of inferior pyramidal drainage screen bucket connects upper blow-off pipe, it is an advantage of the invention that the function not only with three-stage filtration, but also there is the dirt eliminating function of two grades of backwashes, effectively dispose the impurity dirt in filter vat net, scrubbing efficiency is high, resistance is little, dual backwash, sewage load is big.
