The purpose of this utility model is at above-mentioned the deficiencies in the prior art, a kind of middle low speed paper machine slurry flowing box is provided, this head box do not have hanging, turbulent flow evenly, not have rotten lumps, pulp homogeneous and controllable, paper-forming evenness good, can substitute is the existing homogenate roll-type head box that opens wide.
The technical solution of the utility model realizes in the following manner:
Low speed paper machine slurry flowing box in a kind of, comprise into slurry canalis spinalis, advance to starch canalis spinalis and link to each other that A, tube bank I link to each other with the tube bank II by the dilution water plate with the tube bank I, dilution water plate top is provided with the dilution water valve, and dilution water valve two ends link to each other with the dilution water plate with the dilution water canalis spinalis by pipeline; B, tube bank II link to each other with mixing chamber, and mixing chamber links to each other with the tube bank III, and the tube bank III links to each other with the tube bank IV, and the tube bank IV links to each other with the tube bank V, and the tube bank V links to each other with the pond, weir.
Pond, described weir comprises top lip of slice and aulaeum, and the port of export of top lip of slice is provided with the labial lamina bar.
The cross section of tube bank III described in the preferred version and tube bank IV is circular, and tube bank V cross section is square.Long 45 millimeters of described tube bank I, long 45 millimeters of dilution water plate, long 45 millimeters of tube bank II.Long 80 millimeters of described mixing chamber.Long 40 millimeters of described tube bank III, long 130 millimeters of tube bank IV, long 130 millimeters of tube bank V.
Compared with prior art, the utlity model has following advantage:
1. the utility model is applied to this head box with every technology of high speed head box, make it have the advantage of high speed head box, as do not have hanging, do not have rotten lumps, turbulent flow evenly, the pulp homogeneous and controllable, paper-forming evenness is good etc., eliminated existing shortcoming of opening wide homogenate roll-type head box, as hanging, have that rotten lumps, turbulent flow are inhomogeneous, pulp is difficult to control, paper-forming evenness is bad etc., is the existing regeneration product that opens wide homogenate roll-type head box.
2. low speed paper machine slurry flowing box in of the present utility model, when paper machine operation during 200 meters/minute speed of a motor vehicle, head box operational excellence, paper-forming evenness is good, low speed paper machine in success waterpower formula head box is applied to.

The specific embodiment
The utility model comprises into slurry canalis spinalis 2, stepped diffuser, dilution water device, mixing chamber, turbulent flow generator and labial lamina.Wherein stepped diffuser is made up of tube bank I 4, tube bank II 6, the dilution water device is made up of dilution water plate 5, dilution water valve 3 and dilution water awl 1, turbulent flow generator is made up of tube bank III 8, tube bank IV 9 and tube bank V 10, and labial lamina is made up of top lip of slice 11, aulaeum 12 and labial lamina bar 13.
Shown in Fig. 1～4, comprise into slurry canalis spinalis 2, advance to starch canalis spinalis 2 and link to each other that A, tube bank I 4 link to each other with tube bank II 6 by dilution water plate 5 with tube bank I 4, dilution water plate 5 tops are provided with dilution water valve 3, and dilution water valve 3 two ends link to each other with dilution water plate 5 with dilution water canalis spinalis 1 by pipeline; B, tube bank II 6 link to each other with mixing chamber 7, and mixing chamber 7 links to each other with tube bank III 8, and tube bank III 8 links to each other with tube bank IV 9, and tube bank IV 9 links to each other with tube bank V 10, and tube bank V 10 links to each other with the pond, weir.
Pond, described weir comprises top lip of slice 11 and aulaeum 12, and the port of export of top lip of slice 11 is provided with labial lamina bar 13.
The cross section of described tube bank III 8 and tube bank IV 9 is circular, and tube bank V 10 cross sections are square.
