The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises cylindrical shell 7, playpipe assembly 8, shower nozzle 9, nozzle 10, hole bridge insert 14, ring bridge insert 15 and bracing frame 17, one end of its middle cylinder body 7 is communicated with slurry box by elbow 5, the two ends of elbow 5 are respectively equipped with flange 6, and affixed with an end and the slurry box of cylindrical shell 7 respectively by flange 6, the other end of cylindrical shell 7 is connected with the outlet(discharge) flange of band outlet 16.
Cylindrical shell 7 is hollow structure, and playpipe assembly 8 vertically is plugged on cylindrical shell 7.As shown in Fig. 2~5, playpipe assembly 8 comprises playpipe 18 and valve rod 11, and wherein playpipe 18 vertically is plugged on cylindrical shell 7, has the second through hole 21 in the middle of playpipe 18, and the longitudinal center line of this second through hole 21 is perpendicular to the longitudinal center line of cylindrical shell 7; One end of playpipe 18 is communicated with variable pump 1 by tube connector, and the other end is threaded and controls the valve rod 11 of medicinal liquid flow; The axial cross section of this valve rod 11 is "T"-shaped, is inserted by the second through hole 21.Tube connector comprises flexible pipe 2 and steel pipe 3, and wherein steel pipe 3 is fixed on elbow 5 by support 4; One end of flexible pipe 2 is connected with variable pump 1, and the other end is connected with an end of steel pipe 3, and the other end of steel pipe 3 is connected to an end of playpipe 18.
Nozzle 10 is fixed on the playpipe 18 that is positioned at cylindrical shell 7, and the longitudinal center line that has the first through hole 20, the first through holes 20 of being connected with the second through hole 21 and the second through hole 21 on nozzle 10 is perpendicular.One end of shower nozzle 9 is fixed on nozzle 10, and the center of the other end has third through-hole 22, the longitudinal center line conllinear of the longitudinal center line of this third through-hole 22 and the first through hole 20; Be evenly equipped with a plurality of micropores 19 around third through-hole 22.Be provided with cavity 25 in the inside of shower nozzle 9, an end of this cavity 25 is communicated with the first through hole 20 on nozzle 10, and the other end is communicated with third through-hole 22 and each micropore 19.
