Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.
The utility model provides a stirring deaeration device for high strength structure conveyer belt, includes stirring chamber 1 and deaeration chamber 2, and stirring chamber 1 and deaeration chamber 2 are connected through taking the transition duct 12 of first metal filter screen 13 and stop valve 14.
Stirring chamber 1 includes rotation axis 6, mixing hopper 7, mixing barrel 8, stirring rake 10, first pan feeding pipe 4, second pan feeding pipe 5, motor 3 and spiral leaf 11, and 7 lower extremes of mixing hopper and 8 fixed connection of mixing barrel, mixing barrel 8 fixes on rotation axis 6 through connecting rod 9 suit. The first feeding pipe 4 and the second feeding pipe 5 penetrate through the top surface of the stirring cavity 1 and extend into the mixing hopper 7. The rotating shaft 6 is driven by the motor 3 and is rotatably inserted inside the stirring chamber 1. The stirring paddle 10 is arranged on the outer wall of the mixing cylinder 8. The stirring paddle 10 is provided with stirring blades which are in a symmetrical comb shape. Because the viscosity of the polyester plasticizer is high, the stirring blades are arranged in a comb shape, so that the stirring resistance is reduced, the power consumption of the motor 3 is reduced, and the high rotating speed of the mixing hopper 7 and the stirring paddle 10 is ensured.
The spiral blade 11 is arranged on the rotating shaft 6 at a position below the mixing cylinder 8. The blades 11, when rotated with the shaft 6, push the slurry away from the mixing bowl 8, thereby creating a low pressure zone at the lower port of the mixing bowl 8. Through setting up helical blade 11 for the lower port of mixing barrel 8 forms the low-pressure zone, and the thick liquids in the mixing barrel 8 of being convenient for are down fast, avoid mixing barrel 8 to block up.
The first feeding pipe 4 and the second feeding pipe 5 are respectively connected with the corresponding material storage barrel through a material pump at one end outside the stirring cavity 1.
Great polyester plasticizer of viscosity is via first pan feeding pipe 4 respectively with other raw materialss, second pan feeding pipe 5 is gone into in the mixing hopper 7 by the pump, when mixing hopper 7 rotated along with rotation axis 6, polyester plasticizer and other raw materials are collected in proper order to the same position of 7 inside walls of mixing hopper, this in-process polyester plasticizer gets into mixing barrel 8 simultaneously with other raw materialss according to a certain proportion, and go down along mixing barrel 8 and get into the lower part in stirring chamber 1, finally make polyester plasticizer and other raw materials intensive mixing via the stirring effect of stirring rake 10 again, the stirring efficiency is greatly improved.
