The agitator that is used for the viscose glue xanthating machine
(1) technical field
The utility model relates to the viscose rayon production technology, relates to a kind of agitator that is used for the viscose glue xanthating machine specifically.
(2) background technology
Xanthating machine is one of crucial main process equipment during viscose rayon is produced, and along with the expansion gradually of viscose rayon Production Line ability, the production capacity of separate unit xanthating machine is also in continuous increase.Traditional viscose glue xanthating machine adopts slurry formula or kneading type agitator more, but continuous increase along with the xanthating machine volume, the slurry formula of prior art or kneading type agitator can not adapt to the needs that big capacity material stirs, the normal appearance stirred the weak point uneven, that material easily lumps, the agitator bearing torque is excessive in stirring, directly has influence on the product quality of viscose rayon.
(3) summary of the invention
The purpose of this utility model provide with regard to being to overcome above-mentioned weak point of the prior art a kind of structure more scientific and reasonable, stir, can make material fully to mix and the agitator that is used for the viscose glue xanthating machine of prevented from caking.
The purpose of this utility model can realize by following measure:
The agitator that is used for the viscose glue xanthating machine of the present utility model comprises shaft and the paddle that is provided with around shaft; Mode in the shaft stage casing with right-angled intersection is provided with a vertical rod, respectively is provided with a cantilevered scraper at the front and back ends of shaft; Described paddle is a spiral belt structure, and it comprises two outer paddle and two interior paddles that rotation direction is opposite that rotation direction is opposite; Mode in the described outer paddle with dextrorotation arise from the arm-type scraper of front overhang the end, end at an end of vertical rod, another root with left-handed mode arise from vertical rod the other end, end at the end of the arm-type scraper of rear overhang; In described in the paddle one arises from middle part between arm-type scraper of front overhang and the vertical rod, ends at the binding end of outer paddle of dextrorotation and vertical rod in left-handed mode, another root with the mode of dextrorotation arise from left-handed outer paddle and vertical rod binding end, end at the middle part between vertical rod and the arm-type scraper of rear overhang.
Be to increase the intensity of spiral belt paddle, be provided with the reinforcement bar between unsettled section of described paddle and the shaft at the utility model under the prerequisite that does not influence its mixing effect.
The left and right anglec of rotation of outer paddle from its starting point to terminating point of revolving is all about 200 °~220 ° described in the utility model; The anglec of rotation of described left and right medial rotation paddle from its starting point to terminating point is all about 105 °~180 °.
Because it is front and back that the utility model changes the slurry formula or the kneading type agitator of prior art, inside and outside four sections spiral belt paddles, and before and after it, the rotation direction of internal and external screw belt paddle is opposite each other, when agitator rotates, four sections spiral belt paddles advance material to different directions respectively, can make material be able to abundant mixing, and be arranged on shaft before, the cantilevered scraper of rear end can play the effect that sticks in the material on the cylinder inboard wall of wiping off again, this also just makes the utility model compared with prior art not only can make the stirring of material more even, effectively solve the problem of material caking, the problem of material and barrel adhesion easily takes place in the time of also can overcoming discharging simultaneously.

Accompanying drawing is an axonometric drawing of the present utility model.
(5) specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in the figure, the agitator that is used for the viscose glue xanthating machine of the present utility model comprises shaft 1 and the paddle that is provided with around shaft; Be provided with a vertical rod 3 in the shaft stage casing in the mode of right-angled intersection, respectively be provided with a cantilevered scraper 5 and 6 at the front and back ends of shaft; Described paddle is a spiral belt structure, and it comprises two outer paddle 4 and 7 and two interior paddles 2 and 8 that rotation direction is opposite that rotation direction is opposite; Described outer paddle 7 with the mode of dextrorotation arise from the arm-type scraper 6 of front overhang the end, end at an end of vertical rod 3, the outer paddle 4 of another root with left-handed mode arise from vertical rod 3 the other end, end at the end of the arm-type scraper 5 of rear overhang; Paddle 2 arises from middle part between the arm-type scraper 6 of front overhang and the vertical rod 3, ends at the binding end of the outer paddle 7 of dextrorotation and vertical rod 3 in left-handed mode in described, the interior paddle 8 of another root with the mode of dextrorotation arise from left-handed outer paddle 4 and vertical rod 3 binding end, end at the middle part between vertical rod 3 and the arm-type scraper 5 of rear overhang; Be to increase the intensity of spiral belt paddle, be provided with reinforcement bar 9 between unsettled section of described paddle and the shaft at the utility model under the prerequisite that does not influence its mixing effect.
Say that more specifically left and right big I of revolving the anglec of rotation of outer paddle from its starting point to terminating point is set according to the physical length of shaft 1 described in the utility model, can between 200 °~220 °, set, and its two ends are fixed in the end of cantilevered scraper and vertical rod respectively; The big I of the anglec of rotation of described left and right medial rotation paddle from its starting point to terminating point is set according to the physical length of shaft 1, can between 105 °~180 °, set, and the one end is by connecting rod and shaft 1 Joint, and the other end is connected the below of vertical rod 3 ends by affixed mode.
