Detailed Description
The invention will be further described with reference to the accompanying drawings.
Fig. 1 shows a fiber soil mixing apparatus 100 according to the present invention. As shown in fig. 1, the apparatus 100 includes a stirring vessel 1, a stirrer 2, a transfer assembly 3, and a wind gun assembly 4. Wherein the stirring vessel 1 is used for containing raw materials and stirring is performed in the inner cavity of the stirring vessel 1. The stirrer 2 is provided in the inner cavity of the stirring vessel 1 for stirring the material put into the inner cavity of the stirring vessel 1. Further, the stirrer 2 has two rotation shafts 21 disposed horizontally opposite to each other and a stirring member 22 disposed between the rotation shafts 21. A conveyor assembly 3 is provided on the agitator 1 for adding plain soil to the agitation vessel 1. A wind gun assembly 4 is provided on the stirrer 1 for adding fibres to the stirred vessel 1.
Thus, the apparatus 100 adds the fiber to the agitation vessel 1 by the air gun assembly 4 while adding the plain soil to the agitation vessel 1 by the transfer assembly 3, thereby contributing to an improvement in the degree of mixing of the fiber and the plain soil. Meanwhile, due to the fact that the air gun assembly 4 is used, fibers are blown away, and uniformity of fiber addition is guaranteed. In addition, the stirring assembly 22 of the stirrer 2 is supported by the two rotating shafts 21 horizontally arranged, so that the stirring assembly 22 is stressed uniformly, and relatively large stirring force is generated, and the stirring effect is improved.
According to the invention, the stirring assembly 22 has two stirring discs 23. Each stirring disk 23 is fixedly connected with the rotary shaft 21 so as to rotate under the drive of the rotary shaft 21. And, two stirring plates 23 are provided opposite to each other. A stirring rod 24 is provided between the two stirring plates 23 to play a stirring role.
Four stirring rods 24 are lapped between two opposite stirring plates 23. In one embodiment, as shown in fig. 3, in an initial state, in which two stirring rods 24 extend from the highest point and the lowest point of the first stirring disk 23 to the first side center point of the second stirring disk 23, respectively. The other two stirring rods 24 extend from the highest point and the lowest point of the second stirring disk 23 to the second side center point of the first stirring disk 23, respectively. The first side center point and the second side center point are 180 degrees apart. Through this kind of setting can stir the fiber soil in the inner chamber of stirring container 1 fully, avoid layering, this kind of setting can shorten stirring time simultaneously, improves the construction progress, the energy saving.
In another embodiment, as shown in FIG. 2, four stirring rods 24 are lapped over two opposing stirring plates 23. The stirring rods 24 are parallel to each other, and the stirring rods 24 are uniformly distributed in the circumferential direction. Through the arrangement, the stirring rod 24 can drive plain soil and fibers to do high-speed motion, so that the fibers are uniformly distributed in the soil body and the soil body is uniform, and isotropy of the soil body is ensured. In addition, through the arrangement, the dispersing effect of the soil body is guaranteed, and agglomeration is avoided.
According to the invention, a horizontally oriented support bar 27 is arranged between the two stirring discs 23. A support bar 27 is connected to the center of each agitator disk 23. Meanwhile, the support rods 27 are connected to the respective stirring bars 24 through the connection rods 25. By this arrangement, the stirring rod 24 can be connected to the support rod 27, thereby increasing the strength, rigidity and overall stability of the stirring rod 24, preventing the stirring rod 24 from being easily bent or deformed due to the excessive length thereof, and thus increasing the stirring effect. The number and fixed positions of the connecting rods 25 may be adjusted according to the length and cross-sectional area of the stirring rod 24.
A plurality of stirring pins 26 are provided on each stirring rod 24. The plurality of pins 26 on each stirring rod 24 are parallel to each other. On each stirring rod 24, a stirring pin 26 is parallel to a straight line passing through the center point of the stirring rod 25 and the midpoint of the center line of the two stirring plates 23. Preferably, the ratio of the length of the stirrer pin 26 to the radius of the stirrer disc 23 is 0.3-0.8, for example, 0.4. By this arrangement, the contact between the stirring member 22 and the raw material can be increased, and the stirring effect can be enhanced.
In one embodiment, as shown in fig. 1, the agitation vessel 1 has a vessel body 11 and a hemispherical upper cover 12 provided at an upper end of the vessel body 11, and the vessel body 11 and the upper cover 12 are fixedly connected. A first opening 13 for communicating with the transfer assembly 3 is provided in the upper cover 12. Wherein the centre of the first opening 13 is located on a plane 45-55 degrees, e.g. 50 degrees, from the horizontal plane. Wherein the conveyor assembly 3 is configured as a conveyor belt. The setting mode has high working efficiency and can meet the requirement of relatively large-scale plain soil stirring. The agitation vessel 1 has a bottom wall provided obliquely, and a discharge port 14 is provided at the lowest position of the bottom wall. That is, the bottom wall of the agitation vessel 1 is higher and higher in the direction from the middle to the outside, and the discharge port 14 is provided at the center position so that the agitated material can be discharged from the agitation vessel 1 through the discharge port 14. A leg 15 is provided at the lower end of the stirring vessel 1. The legs 15 serve to support the stirred vessel 1. At the same time, the above arrangement can facilitate and ease the collection of the material removed by the exhaust port 14.
In one embodiment, the air gun assembly 4 has a fiber tube 41 fixedly disposed on the upper cover 12. The fiber tube 41 extends toward the center of the upper cover 12. Meanwhile, the extending direction of the fiber tube 41 forms an angle of 78-82 degrees, for example, 80 degrees with the horizontal plane. During operation, the fibers are thrown into the air gun assembly 4, and the fibers blown by the air gun assembly 4 are uniformly scattered into the inner cavity of the stirring vessel 1 by the fiber pipe 41. Through the arrangement, the blowing-off effect of the air gun assembly 4 can be guaranteed, so that the mixing uniformity of fibers and plain soil is guaranteed.
In one embodiment, the liquid spraying tube 5 is fixedly arranged on the upper cover 12. The liquid spraying pipe 5 is extended toward the center of the upper cover 12 to spray the stirring liquid into the inner cavity of the stirring vessel 1. And the extending direction of the liquid spraying pipe 5 forms an included angle of 73-76 degrees, such as 75 degrees, with the horizontal plane.
