Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

As shown in fig. 1, the high-efficiency horizontal biaxial axial flow continuous stirrer comprises a first main shaft 10 and a second main shaft 20, the axes of which are on the same plane and are arranged in parallel relatively, and a plurality of blades 1, 2, 3 and 4 which are respectively installed on the main shafts 10 and 20 along the axial directions at intervals, wherein the blades installed on the first main shaft 10 in the figure are named as a first blade 1 and a second blade 2 respectively according to the distribution arrangement direction of the main shafts relatively, and the blades installed on the second main shaft 20 are named as a third blade 3 and a fourth blade 4 respectively according to the distribution arrangement direction of the main shafts relatively.

On the first main shaft 10, a pair of first blades 1 with the same distribution direction are alternately arranged in the middle of the first main shaft 10, a plurality of second blades 2 with the distribution direction staggered with the distribution direction of the first blades 1 are respectively arranged on the left side and the right side of the first blades 1 alternately, and a first blade 1 is arranged between every two adjacent second blades 2. The two first blades 1 arranged in the middle of the first main shaft 10 are symmetrical by taking a main shaft center line (a dotted line in fig. 1) as a central axis.

In this patent, reference to the centerline of the spindle is not necessarily to a vertical centerline through the midpoint of the axis of the spindle, and is understood to include a vertical centerline through the axial midpoint of the portion mounted within the mixer barrel. In other words, the position of the center line can be determined from the angle of the relative fit between the main shaft and the blade, and the like.

In the embodiment shown in fig. 1, the first blades 1 and the second blades 2 are staggered in the distribution direction on the first main shaft 10, and are intersected with each other when viewed in the axial direction of the first main shaft 10 (projection), and are in a cross shape. Furthermore, viewed axially, (projections of) the first blades 1 are overlapped, and (projections of) the second blades 2 are overlapped. In other embodiments, the first blades 1 and the second blades 2 may be formed in a staggered manner, and when viewed along the axial direction of the first main shaft 10, (the projections of) the first blades 1 and the second blades 2 are mutually crossed and present an X-shaped pattern, at this time, (the projections of) the first blades 1 may also be overlapped, and (the projections of) the second blades 2 may also be overlapped at the same time.

The first paddle 1 and the second paddle 2 are formed in a staggered mode in the distribution direction, when the first paddle 1 and the second paddle 2 are mutually crossed and present in an X-shaped mode when seen in the axial direction of the first spindle 10, the first paddle 1 can be partially overlapped in projection, the second paddle 2 can be partially overlapped in projection, and in other words, different X-shaped included angles formed by the first paddle and the second paddle in a staggered mode are different. Therefore, in this patent, the understanding that the distribution directions of the blades are uniform includes a case where the blades are completely overlapped (in axial projection) and a case where the blades are mostly overlapped (in axial projection) as viewed in the axial direction. Under this patent, if two blades that distribute to set up on the main shaft, see two blades (projection) along the axial and have more than half blade area overlapping, just can understand that the distribution direction of two blades is unanimous. In some application environments, it is more desirable to understand that the blades are distributed in the same direction, and that the blades have projected areas of 2/3 or 3/4 or more than the projected areas of the blades overlap.

As shown in fig. 1, a plurality of fourth blades 4 with distribution directions staggered with respect to the distribution direction of the first pair of blades 1 disposed in the middle of the first main shaft 10 are disposed on the second main shaft 20 at intervals, and a middle one of the fourth blades 4 corresponds to a middle line of a space between the first pair of blades 1 disposed in the middle of the first main shaft 10, that is, the middle one of the fourth blades 4 disposed on the second main shaft 20 corresponds to a main shaft center line (a dotted line in fig. 1), that is, corresponds to a position perpendicular to a center line of an axial distance between the first pair of blades 1 disposed in the middle of the first main shaft 10.

On the second main shaft 20, a third blade 3, the distribution direction of which is consistent with the distribution direction of a pair of first blades 1 arranged in the middle of the first main shaft 10, is arranged between every two adjacent fourth blades 4.

In the embodiment shown in fig. 1, the third blade 3 and the fourth blade 4 are staggered in the distribution direction on the second main shaft 20, and are crossed (projected) in the axial direction of the second main shaft 20, and are in a cross shape. Furthermore, viewed axially, (projections of) the respective third blades 3 overlap and (projections of) the respective fourth blades 4 overlap. Similarly, in other embodiments, the third blade 3 and the fourth blade 4 may be formed in a staggered manner in the distribution direction, and when viewed along the axial direction of the second spindle 20, (the projections of) the third blade 3 and the fourth blade 4 are intersected with each other and present an X-shaped pattern, at this time, (the projections of) the third blades 3 may also be overlapped, and (the projections of) the fourth blades 4 may also be overlapped at the same time.

No. 3 paddles and No. 4 paddles's distribution direction is crisscross formation, looks along the axial direction of second main shaft 20, and No. 3 paddles and No. 4 paddles's projection is intercrossing and when appearing the pattern for X form, and also each No. 3 paddles ' projection can be partial overlapping, and also each No. 4 paddles's projection can be partial overlapping simultaneously, that is to say the X form's that different No. three paddles and No. four paddles crisscross formation contained angle is different. Therefore, in this patent, the understanding that the distribution directions of the blades are uniform includes a case of completely overlapping and a case of mostly overlapping as viewed in the axial direction. If more than half of the blade areas of the two blades are overlapped when viewed along the axial direction, the distribution directions of the two blades are consistent.

Meanwhile, when determining whether the distribution direction of a certain part of blades on the second main shaft is consistent with that of a certain part of blades on the first main shaft, the method is also understood in the above understanding mode of whether the distribution directions of the blades on the same main shaft are consistent.

As shown in fig. 1, each of the first blade 1 and the second blade 2 on the first main shaft 10 corresponds to a space between two adjacent blades, i.e., a third blade 3 and a fourth blade 4, on the second main shaft 20. When the first main shaft 10 and the second main shaft 20 rotate in the same direction (both rotate counterclockwise), the blade end surfaces of the first blade 1 and the third blade 3, and the blade end surfaces of the second blade 2 and the fourth blade 4, which are distributed on the two main shafts 10 and 20, can be partially opposite to each other in the radial direction. In the illustrated state, the blade end faces of the first blade 1 and the third blade 3 which are (directly) adjacent to each other are opposite to each other between the axial distances of the two main shafts (i.e., in the radial direction) to form a gap S ', and at this time, the second blade 2 and the fourth blade 4 are in the direction perpendicular to the paper surface, and in the process that the two main shafts rotate 90 degrees in the counterclockwise direction, the blade end faces of the second blade 2 and the fourth blade 4 which are (directly) adjacent to each other are also opposite to each other between the axial distances of the two main shafts (i.e., in the radial direction) to form a gap S'.

All the blades (blade 1 and blade 2) distributed on both sides of the center line of the first main shaft 10 are symmetrically distributed about the center line.

The double-shaft axial flow continuous stirrer (or called stirring mixer) drives two main shafts of equipment to rotate through a driving device, the main shafts are provided with (stirring) blades which are distributed and staggered to form a certain angle and quantity, materials are subjected to mixing motion in an equipment cylinder along with the rotation of the main shafts, an instant weightless state is produced, when the blades reach a certain circumferential speed, due to the upward throwing acting force on the materials, the materials form a flowing layer in the cylinder, the moving speeds of the materials in each annular section of the cylinder are unequal, and the materials with different sections are continuously and fully mixed through mutual convection.

Because the blades on the two main shafts move in a staggered manner, the material flowing layer forms different compression ratios in different annular sections, and the material is further promoted to gradually push towards the direction with the small compression ratio to achieve the purpose of discharging.

Under the structure shown in fig. 1, the material inlet is arranged in the middle of the first main shaft, the central line is arranged, and the material is conveyed to the two ends of the cylinder body in the axial direction in the cylinder body. The paddle that adopts is straight blade, the axis of paddle perpendicular to main shaft, and two main shafts parallel arrangement syntropy rotation relatively drive the material and move in the circumferencial direction and be stirred the mixture, and stirring effect has stronger shearing force during the mixture, and is effectual to the dispersion of granule.

The rotating speed and the rotating direction of the double blades of the stirring system formed by the double main shafts can be respectively controlled, so that the operation is more free and flexible, and the double-blade stirring system has better application in medium and high viscosity Newtonian fluids and non-Newtonian fluid stirring.

The shaft center position of first main shaft, a pair of paddle syntropy arranges to correspond and form symmetrical structure in the both sides of central line, and can realize the function that middle feed is to (axial) both sides stirring transport, improved production efficiency, reduced the running cost.

The blades on the double main shafts are distributed relatively, so that materials are fully stirred and mixed in the relative rotation process of the double shafts, and meanwhile, partial materials are extruded all the time to form axial driving force in the staggered motion process of the blades of the double shafts, so that the materials move along the axial direction, and the continuous feeding of the materials is realized;

as shown in fig. 1, the end surfaces of the blades are all flat surfaces, and the thickness σ of each blade is uniform. The axial distance S between two adjacent blades (a blade 1 and a blade 2 or a blade 1 and a blade 1) on the first main shaft 10 is the same, and the axial distance S between two adjacent blades (a blade 3 and a blade 4) on the second main shaft 20 is the same. The pitches S on the two main shafts are also identical to each other in size.

Taking the application in the continuous acidolysis process of chemical titanium dioxide as an example, the optimal value of the vertical distance d between the first main shaft 10 and the second main shaft 20 in the axial direction is 760mm, and the up-down floating interval is within 200 mm. The optimal axial distance S between two adjacent first blades 1, the adjacent first blades 1 and second blades 2, and the adjacent third blades 3 and fourth blades 4 is 110mm, and the up-down floating interval is within 30 mm. The gap S' formed between the first blade 1 arranged on the first main shaft 10 and the third blade 3 arranged on the second main shaft 20 which are directly adjacent to each other is optimally 35mm, and the upper and lower floating is within 8 mm.

In other embodiments, a side end face of the blade may be made helicoidal or near helicoidal, which is understood to be helicoidal in the sense of this patent. In some embodiments, the end surface of the paddle is a convex curved surface.

As shown in fig. 2, is a front view (end-on) of various embodiments of the blades 1, 2, 3, 4. In the drawings:

(a) in the illustrated embodiment, the sides of the blade are relatively parallel planes. (b) In the embodiment shown, the side of the blade is an outwardly convex arc, and in contrast, (d) in the embodiment shown, the side of the blade is an inwardly concave arc.

In principle, the arrangement directions of the two blades at the ends of the main shafts should tend to be consistent, as shown in fig. 1, the two end blades a1 and a2 of the first main shaft 10 are both the second-size blades 2, and the two end blades b1 and b2 of the second main shaft 20 are both the fourth-size blades 4, that is, the arrangement directions of the blades a1, a2, b1 and b2 are all approximately the same (including the case where the four blades are imaginarily placed on the same shaft, and the axial projections of the four blades viewed in the axial direction are at least mostly overlapped, and if the contour of the four blades is as large, the projections can be completely overlapped with each other). In other embodiments, the case where the arrangement direction of the blade a1 does not coincide with the arrangement direction of the blade a2, the case where the arrangement direction of the blade b1 does not coincide with the arrangement direction of the blade b2, or the case where the arrangement directions of the blades a1 and a2 do not coincide with the arrangement directions of the blades b1 and b2 is not excluded.
