The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 1～shown in Figure 6, the drawing mechanism 10 of vacuum dryer of the present utility model links to each other with the discharging opening 2 of drying 1, comprise outer tube 3, top discharge pipe 11, bottom discharge pipe 12, valve seat 13 and valve plate 14, outer tube 3 is sheathed on outside the bottom discharge pipe 12, and its bottom all is connected with discharging opening 2 with the bottom of bottom discharge pipe 12, top discharge pipe 11 is located at the top of bottom discharge pipe 12, valve seat 13 has valve opening 15 and is fixedly arranged on the upper end of outer tube 3, the upper end height that highly is higher than bottom discharge pipe 12, and valve opening 15 communicates with outer tube 3 inside, also be provided with lift drive mechanism 16 on the top discharge pipe 11, pass 12 butt joints of valve opening 15 and bottom discharge pipe or separate in order to control top discharge pipe 11, valve plate 14 is located at valve seat 13 1 sides top, one end is provided with translational drive mechanism 17, cross out or withdraw in order to control valve plate 14, thereby close or open valve opening 15.The upper end of described bottom discharge pipe 12 is as the convex port (round table-like) among Fig. 2～Fig. 6, the lower end of top discharge pipe 11 is the female port that is complementary, and so, can guarantee the interlock sealing between the two-port when butt joint, guarantee sealing between pipe, prevent the leakage of material.Described valve seat 13 upper surfaces also are provided with O shape circle 20, when valve plate 14 crosses out, cover when closing on valve opening 15 and O shape circle 20, press down valve plate 14 and O shape circle 20 by lift drive mechanism 16 control top discharge pipes 11, with the sealing that guarantees that valve plate 14 is closed.And there is radial clearance in the upper end of described valve opening 15 and bottom discharge pipe 12, so, when discharging finishes, when top discharge pipe 11 rises, the partial material that resides in the valve opening 15 can fall from the gap, and along the male end oral-lateral portion landing (seeing the oblique dotted arrow among Fig. 4) of bottom discharge pipe 12, be back in the drying 1 by outer tube 3, thereby avoid remaining in the valve opening 15 and valve seat 13 first-class positions, cause blocking valve plate 14, cause problems such as sealing is not good, thereby more be conducive to guarantee the air-tightness of drawing mechanism 10 and whole vacuum dryer.Described lift drive mechanism 16 comprises the cylinder 18a that arranges straight down, and the piston rod of cylinder 18a is connected with top discharge pipe 11 by fixed mount 19.Described translational drive mechanism 17 comprises horizontally disposed cylinder 18b, and the piston rod of cylinder 18b is connected with valve plate 14 1 ends.Certainly, lift drive mechanism 16 and translational drive mechanism 17 are not limited only to adopt cylinder 18a, also can adopt other as driving mechanisms such as hydraulic cylinder, driven by power.
