Abstract
The utility model discloses a kind of flocculation passage of papermaking sewage treatment system, including the water inlet pipe for connecting setting pot and the outlet pipe for connecting settling tank, and the chemical feed pipe of connection flocculant case, it is connected with the first reducing pipe, the first increaser, negative pressure chamber, the second reducing pipe and the second increaser between the water inlet pipe and outlet pipe in turn, the second reducing pipe butt end is arranged at immediately ahead of the first increaser butt end, and second the butt diameter of reducing pipe be more than the first increaser butt diameter, the chemical feed pipe connects negative pressure chamber.According to Venturi effect, sewage is during through the first reducing pipe, the first increaser, negative pressure chamber, the second reducing pipe, the second increaser, negative pressure can be formed in negative pressure chamber, flocculant be drawn from flocculant case by chemical feed pipe, the flow velocity of sewage is faster, negative pressure value is higher, the flow velocity of flocculant is faster, and the automatic change in flow for adapting to sewage, promptness, accuracy are good, and be the mechanical structure of no abrasion, cost is low, fault rate is low.
Description
Technical field
It the utility model is related to papermaking sewage treatment system field, and in particular to a kind of flocculation of papermaking sewage treatment system
Passage.
Background technology
The manufacturing process of corrugated paper includes to be re-fed into paper machine as waste carton crushing, the slurrying of raw material and paper is made,
Substantial amounts of sewage can be produced in the fabrication process, it is necessary to could be discharged or be reused after being handled；The passage that flocculates is papermaking
An important step in sewage disposal system, its effect is to mix sewage with flocculant, so as to by the nuisance in sewage
Matter is separated；Existing flocculation passage is generally directly to connect Sheng by chemical feed pipe with the pipeline of settling tank in connection setting pot
The container of flocculant is put, the natural flowing of flocculant is realized by chemical feed pipe both ends difference in height, or conveyed by pump；Sewage
Composition it is substantially stationary, also generally fixed with the adding proportion of flocculant, existing flocculation passage is sent out in the flow velocity of sewage
Can only adjust flocculant flow velocity by changing the aperture of valve on chemical feed pipe during changing, the promptness of manual modulation valve door and
Accuracy is all very poor, realizes that the cost for automatically adjusting valve is high by sensor to detect sewage and flocculant flow velocity, and adopt
Electronic device is more, fault rate is higher.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of flocculation passage of papermaking sewage treatment system, can solve
Certainly existing flocculation passage adjusts flocculant flow velocity by changing valve opening, and the promptness and accuracy of manual modulation valve door are all
Very poor, cost height, the fault rate for automatically adjusting valve are higher.
The utility model is achieved through the following technical solutions：
A kind of flocculation passage of papermaking sewage treatment system, including connection setting pot water inlet pipe with connect going out for settling tank
Water pipe, and the chemical feed pipe of connection flocculant case, the first reducing pipe, first are connected with turn between the water inlet pipe and outlet pipe
Increaser, negative pressure chamber, the second reducing pipe and the second increaser, the second reducing pipe butt end are being arranged at the first increaser butt end just
Front, and the butt diameter of the second reducing pipe is more than the first increaser butt diameter, the chemical feed pipe connects negative pressure chamber.
Further scheme of the present utility model is to be also provided at mixing between second reducing pipe and the second increaser
Pipe.
Further scheme of the present utility model is that first reducing pipe, the first increaser, the second reducing pipe and second are gradually
Expander is coaxially disposed in housing.
Further scheme of the present utility model is to be provided with valve on the chemical feed pipe.
The utility model compared with prior art the advantages of be：
First, according to Venturi effect, sewage through the first reducing pipe, the first increaser, negative pressure chamber, the second reducing pipe,
During second increaser, negative pressure can be formed in negative pressure chamber, flocculant is drawn from flocculant case by chemical feed pipe, sewage
Flow velocity is faster, and negative pressure value is higher, and the flow velocity of flocculant is faster, and the automatic change in flow for adapting to sewage, promptness, accuracy are good,
And be the mechanical structure of no abrasion, cost is low, fault rate is low；
2nd, mixing tube extends the incorporation time of flocculant and sewage, strengthens mixed effect；
3rd, housing is realized to the first reducing pipe, the first increaser, the second reducing pipe and the second increaser and protected, it is ensured that is made
Use the life-span.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of flocculation passage of papermaking sewage treatment system as shown in Figure 1, including connect the water inlet pipe 1 of setting pot and connect
The outlet pipe 2 of logical settling tank, and the chemical feed pipe 4 of flocculant case 3 is connected, valve 5 is provided with the chemical feed pipe 4, in addition to
The first connected reducing pipe 6 of coaxial order, the first increaser 7, negative pressure chamber 11, the second reducing pipe 8, mixing tube 9 in housing 12
With the second increaser 10, the butt end of the second reducing pipe 8 is arranged at immediately ahead of the butt end of the first increaser 7, and the second reducing pipe 8
Butt diameter is more than the butt diameter of the first increaser 7, and the water inlet pipe 1 connects the butt end of the first reducing pipe 6, and the outlet pipe 2 connects
The logical butt end of second increaser 10, the chemical feed pipe 4 connect negative pressure chamber 11.
