DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] like Figure 1-4 As shown, a raw material mixing and stirring device for producing phosphogypsum masonry binder comprises a bottom plate 1, a barrel body 2 and a barrel cover 3. Vertical frames 11 are symmetrically arranged on the bottom plate 1. Rotating shafts 21 are arranged on the left and right positions of the outer surface of the barrel body 2. The rotating shaft 21 is inserted in the upper position of the vertical frame 11. The rotating shaft 21 can rotate in the vertical frame 11. The barrel cover 3 is detachably mounted on the mouth of the barrel body 2 by bolts. A counterweight block 32 is arranged on the upper surface of the barrel cover 3. In this way, with the rotating shaft 21 as the center line, the weight of the upper and lower parts of the whole stirring device is roughly the same;

[0029] The outer side of the vertical frame 11 is provided with a side frame 13, and the upper surface of the side frame 13 is provided with a reduction motor 14. The driving shaft of the reduction motor 14 is connected to the rotating shaft 21 through a coupling. The side frame 13 supports the reduction motor 14. When the reduction motor 14 works, it can drive the barrel body 2 to rotate slowly.

[0030] A top frame 24 is provided at the entrance of the barrel body 2. The top frame 24 is in a "cross" shape, and the middle of the top frame 24 is circular. A stirring motor 25 is vertically provided on the top frame 24. The driving shaft of the stirring motor 25 passes through the top frame 24 downward and is installed with a middle shaft 4 through a coupling. The stirring motor 25 can drive the middle shaft 4 to rotate;

[0031] The central axis 4 is vertically located in the middle of the barrel body 2 , and a plurality of stirring rods 41 are evenly arranged on the surface of the central axis 4 at equal intervals from bottom to top.

[0032] There are four stirring rods 41 in each layer, which are evenly distributed around the central axis 4 at equal intervals. The stirring rods 41 of the upper and lower adjacent layers are staggered. The rotation of the central axis 4 drives the stirring rods 41 to rotate. The stirring rods 41 can stir phosphogypsum, fine aggregate, filler and organic high molecular polymer masterbatch.

[0033] An axle seat 42 is provided at the central position of the inner bottom surface of the barrel body 2, and the lower end of the central axis 4 is inserted into the axle seat 42, so that the rotation of the central axis 4 is more stable.

[0034] The cross-section of the stirring rod 41 is diamond-shaped, and the thickness of the stirring rod 41 gradually becomes thinner from the middle to the edges on both sides, so that the resistance of the stirring rod 41 to stirring the powdered raw materials is relatively small. An ultrasonic transducer 5 is arranged inside the front end of the stirring rod 41, and a plurality of through holes 43 are also arranged at the front end of the stirring rod 41. The ultrasonic waves generated by the ultrasonic transducer 5 can pass through the through holes 43 and contact the materials in the barrel body 2, so as to make the powdered materials vibrate and facilitate sufficient stirring and mixing.

[0035] A plurality of uniformly circumferential first through holes 31 are arranged on the mouth fold of the barrel cover 3 , and a plurality of uniformly circumferential second through holes 23 are arranged on the mouth fold of the barrel body 2 .

[0038] The reduction motor 14 rotates slowly, which can drive the barrel body 2 and the barrel cover 3 to rotate in a circle. During the rotation of the barrel body 2, the powdered material in the barrel body 2 swings back and forth in the vertical direction, and then combined with the stirring rod 41 to stir the material in the horizontal direction, the materials can be mixed more fully, and the mixing effect is better.
