Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the stirring tank of the present invention includes a stirring tank 1, wherein a circular turntable 2 is respectively installed at two ends of the stirring tank 1, a first stirring shaft 3 and a second stirring shaft 4 are arranged in the stirring tank 1, the two stirring shafts are parallel, each end of each stirring shaft is rotatably inserted into the turntable 2, a radial stirring tooth 5 is fixed on each stirring shaft, and the two stirring shafts can rotate while revolving along with the turntable 2; the distance between the first stirring shaft 3 and the circle center of the rotary table 2 is greater than the distance between the second stirring shaft 4 and the circle center of the rotary table 2, and the first stirring shaft 3 and the second stirring shaft 4 are respectively positioned at two sides of the circle center of the rotary table 2.

The first stirring shaft 3 and the second stirring shaft 4 extend out of the stirring tank 1 from the same end of the stirring tank 1, a bilateral gear ring 6 coaxial with the rotary table 2 is fixed on the outer wall of the end of the stirring tank 1, external teeth are arranged on the outer side of the bilateral gear ring 6, internal teeth are arranged on the inner side of the bilateral gear ring 6, a first gear 7 is fixed on the end of the first stirring shaft 3, the first gear 7 is meshed with the outer sides of the bilateral gear ring 6, a second gear 8 is fixed on the end of the second stirring shaft 4, and the second gear 8 is meshed with the inner sides of the bilateral gear ring 6; when the two stirring shafts revolve along with the turntable 2, the two stirring shafts rotate in opposite directions under the action of the first gear 7, the second gear 8 and the bilateral gear ring 6.

The gear rings 6 on the two sides are fixed on the outer wall of the stirring tank 1 through a plurality of fixing rods 9.

One of the turntables 2 is coaxially fixed with a third gear 10 positioned outside the stirring tank 1, a fourth gear 11 is installed on the outer wall of the stirring tank 1, the third gear 10 is meshed with the fourth gear 11, the fourth gear 11 is connected with a driving motor, and the driving motor drives the turntables 2 to rotate through the third gear 10 and the fourth gear 11.

The stirring teeth 5 on the first stirring shaft 3 and the second stirring shaft 4 are staggered in the axial direction, so that teeth beating is avoided.

The utility model discloses when using, treat that the material of mixing adds behind the stirred tank 1, start driving motor, driving motor drives carousel 2 through third gear 10 and fourth gear 11 and rotates, and first (mixing) shaft 3 and second (mixing) shaft 4 revolve along with carousel 2, rotation and rotation opposite direction when consequently first gear 7 and second gear 8 revolve round the revolution of two side ring gears 6 to it stirs the mixture with opposite direction rotation to drive two (mixing) shafts to the material.

When two stirring shafts pass through the same position in sequence, the motion path of the top of the stirring tooth 5 on any stirring shaft when the stirring shaft rotates at the position is tangent to or intersected with the motion path of the root of the stirring tooth 5 on another stirring shaft when the stirring shaft rotates at the position, for example, when the second stirring shaft 4 rotates to the left, the second stirring shaft stirs materials close to the inner side of the stirring tank 1, then when the first stirring shaft 3 rotates to the left, the materials close to the outer side of the stirring shaft are stirred, and the stirring position of the top of the stirring tooth 5 of the first stirring shaft 3 is just the stirring position of the root of the stirring tooth 5 of the second stirring shaft 4 when the second stirring shaft 4 is at the position, and the same is true, the stirring position of the root of the stirring tooth 5 of the first stirring shaft 3 is just the stirring position of the top of the stirring tooth 5 of the second stirring shaft 4 when the second stirring shaft is at the position, therefore, at the same position, the top and the root of the stirring teeth 5 of the two stirring shafts are complementary, so that the stirring force at each position is uniform.
