[0044] Please refer to the attached Figures 1 to 11 , the present application provides an embodiment of a cantilever paddle eccentric arrangement horizontal mixer, including frame 10, mixing cylinder 20, first stirring assembly 30 and second stirring assembly, the mixing cylinder 20 is obliquely installed on the frame 10, wherein the mixing cylinder 20 is rotatably arranged around its own central axis, the mixing cylinder 20 includes feed end 210 and discharge end 220, the feed end 210 is higher than the discharge end 220, the mixing cylinder 20 drives the mixing material 50 to overturn and slide from the feed end 210 to the discharge end 220;

[0045] As Figure 4 shown, the mixing cylinder 20 is obliquely installed on the frame 10, preferably, the inclination angle of the mixing cylinder 20 is set to 1.5°~3.5°, the mixing material 50 enters into the inside of the mixing cylinder 20 from the feed end 210, the mixing material 50 entering into the mixing cylinder 20 will first fall to the first stirring assembly 30 and then scatter in the inside of the mixing cylinder 20, under the rotation of the mixing cylinder 20, the mixing material 50 in the cylinder is continuously brought to a certain height and then falls and rolls, the overturning principle diagram is shown in Figure 3 , since the mixing cylinder 20 is obliquely arranged, the mixing material 50 moves forward along the extension direction of the mixing cylinder 20 to the discharge end 220 for discharge.

[0046] The first stirring assembly 30 includes first stirring section 310 and first mounting section 320, the first mounting section 320 is installed on the feed end 210, the first stirring section 310 is rotatably arranged in the mixing cylinder 20, the first stirring section 310 extends from the first mounting section 320 towards the discharge end 220 and is cantilevered; the second stirring assembly includes second stirring section 410 and second mounting section 420, the second mounting section 420 is installed on the discharge end 220, the second stirring section 410 is rotatably arranged in the mixing cylinder 20, the second stirring section 410 extends from the second mounting section 420 towards the feed end 210 and is cantilevered, the second stirring section 410 and the first stirring section 310 are spaced apart;

[0047] As Figures 4-5 shown, the first stirring section 310 extends from the first mounting section 320 towards the discharge end 220 and is cantilevered, and the second stirring section 410 extends from the second mounting section 420 towards the feed end 210 and is cantilevered, that is, the first stirring section 310 and the second stirring section 410 are cantilevered in the interior of the mixing drum 20, and the mixed material 50 after being received, falling and stirred by the first stirring section 310 will move towards the second stirring section 410 under the rotation of the mixing drum 20, and the mixing effect is significantly improved under the forced stirring action of the second stirring section 410. It is worth noting that when the structure scheme of the present application is applied, if the traditional horizontal mixer of the sintering plant is modified, the cantilever structure can greatly reduce the amount of modification, and the modification can be realized by cutting off part of the components, greatly reducing the amount of modification and the cost of modification.

[0048] Further, the length of the first stirring section 310 and the length of the second stirring section 410 are both less than the interval distance between the second stirring section 410 and the first stirring section 310, specifically, the length of the first stirring section 310, the length of the second stirring section 410 and the interval distance between the second stirring section 410 and the first stirring section 310 can be set by the person skilled in the art as needed, for example, according to the length of the traditional horizontal mixer, the length of the traditional horizontal mixer of the existing sintering plant is generally above 14m. In addition, the length of the first stirring section 310 and the length of the second stirring section 410 can be equal or different, which can be determined according to actual needs.

[0049] The first stirring section 310 and the second stirring section 410 are both used for stirring the mixed material 50 in the mixing drum 20, the rotation axis of the first stirring section 310 and the rotation axis of the second stirring section 410 are both eccentrically arranged with the rotation axis of the mixing drum 20, and the rotation axis of the first stirring section 310 and the rotation axis of the second stirring section 410 are both located on one side close to the accumulation area of the mixed material 50 in the mixing drum 20.

[0050] As Figure 3 and Figure 6 shown, the mixed material 50 in the mixing drum 20 will concentrate in the third quadrant area under the rotation of the mixing drum 20, and constantly roll under the rotation of the mixing drum 20, it is worth noting that the rotation axis of the first stirring section 310 and the rotation axis of the second stirring section 410 are both eccentrically arranged with the rotation axis of the mixing drum 20, and the rotation axis of the first stirring section 310 and the rotation axis of the second stirring section 410 are both located on one side close to the accumulation area of the mixed material 50 in the mixing drum 20.

[0051] AsFigure 6 As shown, the second stirring section 410 is close to one side of the mixed material 50 accumulation area, so as to forcibly stir the mixed material 50 in the accumulation area. Compared with the traditional horizontal intensive mixer, because the forward pushing force is generated by the inclined rotation of the mixing cylinder 20, the stirring assembly does not need to provide the forward pushing force, or only needs to provide a little bit of auxiliary pushing force. In addition, as shown, Figure 7 As shown, the material falling from the feeding end 210 first falls on the first stirring section 310, and is scattered in the interior of the mixing cylinder 20 under the rotation of the first stirring section 310, and is still mainly concentrated in the third quadrant area under the rotation of the mixing cylinder 20. Figure 6 As shown, the first stirring section 310 can also forcibly stir the material accumulated in the mixed material 50 accumulation area, and the mixing effect is higher. By arranging the first stirring section 310, the material can be prevented from being concentrated and accumulated during the feeding. Under the action of the first stirring section 310, the mixed material 50 is not directly concentrated and falls into the mixing cylinder 20 during the feeding, and then the mixed material 50 is widely scattered in the mixing cylinder 20 under the action of the rotation centrifugal force of the first stirring section 310. The mixed material 50 after being received, scattered and stirred by the first stirring section 310 moves towards the second stirring section 410 under the rotation action of the mixing cylinder 20, and the mixing effect is significantly improved under the forced stirring action of the second stirring section 410. Compared with the traditional horizontal mixer, not only the material scattering range is increased, but also the mixing effect is improved.

[0052] Through the research on the material overturning and accumulation principle, the first stirring assembly 30 and the second stirring assembly are cooperated with the mixing cylinder 20, the cylinder rotation drives the mixed material 50 to overturn and slide forward, the eccentrically arranged first stirring assembly 30 and the second stirring assembly forcibly stir the mixed material 50, the mixing effect of the horizontal mixer is greatly improved, the efficiency is higher, and the mixing time is shortened. If the mixing effect is the same, the structure of the equipment can be greatly reduced, the wear resistance requirement of the first stirring assembly 30 and the second stirring assembly is low, the manufacturing cost is reduced, and the factory space requirement is reduced.

[0053] As a preferred embodiment, as shown, Figure 4 , 5, 7, the first stirring section 310 includes a first rotating shaft 311, and a bucket blade assembly (not shown in the figure) mounted on the peripheral wall of the first rotating shaft 311, wherein the rotating axis of the first rotating shaft 311 and the rotating axis of the mixing cylinder 20 are arranged eccentrically and located on the side close to the mixing material 50 accumulation area in the mixing cylinder 20; the bucket blade assembly rotates synchronously with the first rotating shaft 311 to receive the material from the feeding end 210 and scatter it in the mixing cylinder 20. It should be noted that the bucket blade assembly is in the shape of a long strip, similar to a ship, so it can cover a large area of the mixing cylinder 20, can receive most of the material from the feeding end 210, and can drive the mixing material 50 to turn and scatter in the mixing cylinder 20.

[0054] Further, the bucket blade assembly includes a plurality of bucket blade units (not shown in the figure) arranged along the extension direction of the first rotating shaft 311, each of which includes a plurality of bucket blades 312 uniformly arranged around the first rotating shaft 311, the bucket blades 312 are in the shape of a long strip and extend from the first rotating shaft 311 towards the inner wall of the mixing cylinder 20, and the bucket blades 312 are used to receive the material from the feeding end 210 and scatter it in the mixing cylinder 20.

[0055] As shown in Figure 4 , 5 , 11, the bucket blade 312 is in the shape of a bucket, and the bucket length (radial dimension of the mixing cylinder 20) of the bucket blade 312 is long, so the bucket blade 312 can not only receive the mixing material 50 from the feeding end 210, but also drive the mixing material 50 to rotate to a certain angle and then scatter, and because the bucket length is long, the mixing material 50 can be scattered in a large range, avoiding the phenomenon of concentrated material accumulation in the traditional horizontal mixer, in addition, the rotation of the bucket blade 312 can forcibly stir the mixing material 50 accumulated in the mixing cylinder 20, increasing the mixing effect.

[0056] As a preferred embodiment, the second stirring section 410 includes a second rotating shaft 411, and a plurality of stirring units 412 mounted on the peripheral wall of the second rotating shaft 411, each of which includes a mounting base (not shown in the figure), a stirring paddle 4121, and a shovel 4122, wherein the rotating axis of the second rotating shaft 411 and the rotating axis of the mixing cylinder 20 are arranged eccentrically and located on the side close to the mixing material 50 accumulation area in the mixing cylinder 20;

[0057] The mounting base is connected to the peripheral wall of the second rotating shaft 411 and moves synchronously with the second rotating shaft 411. The stirring paddle 4121 is fixedly connected to the mounting base and extends toward the inner wall of the mixing cylinder 20. The bucket 4122 is connected to the end of the stirring paddle 4121 away from the mounting base. The radial length of the bucket 4122 along the second rotating shaft 411 is less than the radial length of the bucket blade 312 along the first rotating shaft 311. The bucket 4122 is used to scoop up the mixture 50 and throw the mixture 50 upwards before it falls back down.

[0058] Furthermore, because the rotation of the mixing cylinder 20 causes the material to segregate and pile up more concentratedly, resulting in a thicker material layer, in order to stir and lift as much material as possible, this embodiment adopts a shovel-type or concave spoon-type structure to lift more material and then disperse it for thorough mixing. Therefore, under the rotation of the cylinder, the mixed material 50 is concentrated in the 90-degree area of ​​the lower part of the cylinder in the direction of rotation, where it accumulates, tumbles, and mixes. At the same time, under the strong dispersion of the eccentric stirring paddle 4121, the material undergoes secondary high-speed cutting, upward throwing, and scattering mixing, achieving efficient and uniform mixing of the material.

[0059] Furthermore, the mounting base and the first rotating shaft 311 can be fixed together by bolts or other detachable structures.

[0060] Furthermore, the bucket 4122 includes a first bottom plate 41221, a second bottom plate 41222, and two side plates 41223 respectively connected to both sides of the first bottom plate 41221. The first bottom plate 41221, the second bottom plate 41222, and the two side plates 41223 together form a bucket 4122 with an opening 41224. The first bottom plate 41221 is fixedly connected to the stirring paddle 4121.

[0061] like Figure 6 , 8 As shown in -11, this embodiment adopts a bucket 4122 structure, which can scoop up more mixed material 50. After the bucket 4122 is rotated, the mixed material 50 is unloaded from the right side and falls to the right side of the mixing cylinder 20. Then, under the rotation of the mixing cylinder 20, it is brought to the left stacking area to participate in mixing again, forming a mixing cycle mode with high mixing efficiency.

[0062] In a preferred embodiment, the first base plate 41221 is a flat plate, and the angle between the plane containing the extension directions of the first base plate 41221 and the stirring paddle 4121 is... :in, The angle between the extending direction and the vertical direction of the agitator 4121 when the bucket 4122 is just rotated to the position corresponding to the rotation center of the mixing cylinder 20. It should be noted that the plane containing the extending direction of the agitator 4121 can be any plane containing the central axis of the agitator 4121, for example, it can be... Figure 6 The plane shown. The material lifting angle refers to the angle between the line connecting the center of gravity of the accumulated material and the rotation center of the mixing cylinder 20 after the center of gravity of the material is lifted, and the vertical center line of the cross section of the mixing cylinder 20.

[0063] Furthermore, the included angle Specifically, it is obtained through the following steps:

[0064] When the bucket 4122 is just rotated to the position corresponding to the rotation center of the mixing cylinder 20, the angle between the extension direction and the vertical direction of the stirring paddle 4121 is obtained. According to the included angle Determine the angle θ between the first base plate 41221 and the horizontal plane; where θ is less than or equal to the material's angle of repose of 35°; according to the formula 35° is obtained as an included angle .

[0065] It is worth noting that, such as Figures 5-6 As shown, by rotating the bucket 4122, the mixture 50 is unloaded from the right side and falls onto the right side of the cylinder. Then, under the rotation of the mixing cylinder body 240, it is carried to the left-side stockpile area to participate in mixing again. In order to deliver the mixture 50 to the right side as much as possible, the bucket 4122 should rotate past the rotation center of the mixing cylinder body 20 (i.e., corresponding to angle α) before starting to unload. At this time, the angle θ between the first bottom plate 41221 of the bucket 4122 and the horizontal plane should be less than the material's angle of repose of 35°, i.e., θ≤35°. Figure 8 As shown, θ = 180° - γ - (90° - α) = 90° - γ + α ≤ 35°, therefore, the angle γ between the first bottom plate 41221 of the bucket 4122 and the plane where the stirring paddle 4121 is located is ≥ α + 55°. That is, when the angle between the first bottom plate 41221 and the plane where the extension direction of the stirring paddle 4121 is located satisfies this condition, the dispersion and mixing effect can be greatly improved. For example, the material that was previously scattered can re-enter the left-side area under the action of the mixing cylinder 20 for a second mixing, thereby greatly improving the mixing effect. Through the movements of shoveling, stirring, throwing, scattering, and re-participating in mixing by the bucket 4122, efficient and uniform mixing of materials is achieved.

[0066] Furthermore, the second base plate 41222 is a flat plate or an arc-shaped plate. For example... Figures 9-11The form of the second bottom plate 41222 can be set by those skilled in the art according to actual needs, and can adopt Figure 9 an arc-shaped plate, or a flat plate as shown in FIG. 11. Figure 10

[0067] Further, the plurality of stirring units 412 are arranged in a spiral on the second rotating shaft 411. As shown in FIG. 12, the plurality of stirring units 412 are arranged in a spiral along the extension direction of the second rotating shaft 411, which has the advantage of facilitating the sliding movement of the mixture from the feeding end 210 to the discharging end 220 in cooperation with the inclined mixing cylinder 20, and reducing the resistance of the stirring units 412. Figures 4-5

[0068] Further, the first mounting section 320 comprises a first driving mechanism 321, a third rotating shaft 322, and a first bearing seat (not shown in the figure), the third rotating shaft 322 is mounted on the feeding end 210 through the first bearing seat, the third rotating shaft 322 is connected with the first driving mechanism 321, and the third rotating shaft 322 is fixedly connected with the first rotating shaft 311.

[0069] Specifically, the first driving mechanism 321 can adopt a motor or hydraulic drive, and drive the first rotating shaft 311 and the third rotating shaft 322 to rotate synchronously through the configuration of a speed reducer. In a preferred example, the first rotating shaft 311 and the third rotating shaft 322 are integrally formed, i.e., one shaft. The driving motor and the speed reducer can be arranged at an angle of 90 degrees with the third rotating shaft 322, or can be arranged in series at an angle of 180 degrees. In order to adapt to the cantilever structure of the first stirring section 310 and improve the structural stability, the first bearing seat preferably adopts two.

[0070] Further, the second mounting section 420 comprises a second driving mechanism 421, a fourth rotating shaft 422, and a second bearing seat (not shown in the figure), the fourth rotating shaft 422 is mounted on the discharging end 220 through the second bearing seat, the fourth rotating shaft 422 is connected with the second driving mechanism 421, and the fourth rotating shaft 422 is fixedly connected with the second rotating shaft 411.

[0071] Specifically, the second driving mechanism 421 can adopt a motor or hydraulic drive, and drive the second rotating shaft 411 and the fourth rotating shaft 422 to rotate synchronously through the configuration of a speed reducer. In a preferred example, the second rotating shaft 411 and the fourth rotating shaft 422 are integrally formed, i.e., one shaft. The driving motor and the speed reducer can be arranged at an angle of 90 degrees with the fourth rotating shaft 422, or can be arranged in series at an angle of 180 degrees.

[0072] ​​Further, the mixing cylinder 20 comprises a third driving mechanism 230 and a mixing cylinder body 240, a rolling ring 250 and a first supporting wheel 260 are connected to the outer peripheral wall of the mixing cylinder 20, a second supporting wheel 110 corresponding to the first supporting wheel 260 is installed on the frame 10 to support the mixing cylinder body 240, and the third driving mechanism 230 drives the rolling ring 250 to drive the mixing cylinder body 240 to rotate around the central axis thereof. Figure 4 As a preferred example, the third driving mechanism 230 can adopt a motor or hydraulic drive, and through the configuration of a speed reducer and a gear, the gear and the rolling ring 250 are engaged to drive the rolling ring 250 on the mixing cylinder body 240 to rotate, thereby driving the mixing cylinder body 240 to rotate around the central axis thereof, as shown in Figs. 5 and 6.

[0073] Further, the rotation direction of the mixing cylinder 20, the rotation direction of the first rotating shaft 311 and the rotation direction of the second rotating shaft 411 are the same.

[0074] As shown in Fig. 6, the rotation direction of the first rotating shaft 311 can be the same as or different from the rotation direction of the mixing cylinder 20, and the rotation direction of the second rotating shaft 411 can be the same as or different from the rotation direction of the mixing cylinder 20, for example, both are clockwise, as shown in Fig. 6. Figure 6 Figure 6 In this case, after the mixing cylinder body 240 rotates to continuously bring the materials to a certain height, the materials are thrown down and tumbled, and most of them are accumulated in the region corresponding to the third quadrant, the second driving mechanism 421 drives the second rotating shaft 411 to drive the fourth rotating shaft 422 to rotate, thereby driving the shovel 4122 to rotate clockwise, at this time, the mixed materials 50 are unloaded from the right side and then fall to the right side of the mixing cylinder body 240, and then are brought to the left side of the material accumulation area under the rotation of the mixing cylinder body 240 to participate in the mixing again, it can be seen that the shovel 4122 not only can shovel the materials, drive the materials to fall after being thrown up, but also can achieve the bidirectional mixing effect of the rotation mixing of the mixing cylinder body 240 and the mixing of the stirring assembly, greatly improving the mixing efficiency, and this mode can also adapt to the rotation direction of the mixing cylinder body 240 to continuously circulate the mixing and stirring.
