DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-Figure 7 The raw material mixing device for producing petrochemical products shown in the figure comprises a stirring tank 1, a discharge port 2 is arranged at the bottom of the outer wall of the stirring tank 1, a sealing cover 4 is clamped on the top of the stirring tank 1, a stirring assembly is arranged inside the stirring tank 1, the stirring assembly comprises a motor 3 fixedly mounted on the top of the sealing cover 4, a rotating shaft 5 is fixedly connected to the output end of the motor 3, and the rotating shaft 5 is rotatably connected and inserted to extend below the sealing cover 4, an end of the rotating shaft 5 is fixedly connected to a uniformly distributed connecting arm 21, a cutting body 22 is fixedly connected to the outer wall of the connecting arm 21, a plug plate 27 is fixedly connected to the other side of the connecting arm 21, a pushing body 23 arranged in a cavity structure is slidably connected to the outer wall of the plug plate 27, and the plug plate 27 is inserted and extends to the inside of the pushing body 23, a pressing plate 28 is fixedly connected to the outer wall of the plug plate 27, and the pressing plate 28 and the plug plate 27 form a cross structure, the cutting body 22 comprises a sharp portion 29 fixedly connected to one side of the connecting arm 21, and the sharp portion 2 Both ends of one side of 9 are fixedly connected with transition parts 26, and one side of the transition part 26 is fixedly connected with an abutment part 33. The motor 3 drives the rotating shaft 5 to rotate, which can then drive the connecting arm 21 to rotate, and correspondingly drive the cutting body 22 to rotate to stir the raw materials inside the mixing tank 1 to improve its mixing efficiency. During the process, the sharp part 29 forms a sharp and smoothly transformed cut surface with the transition parts 26 on both sides, which can provide a strong shear force to make the raw materials inside the mixing tank 1 circulate, and then cut the internal raw materials and quickly break the interface between the raw materials, thereby improving the mixing and circulation efficiency of the materials. When the motor 3 switches the rotation direction, the pushing body 23 is used as a contact surface to contact the raw materials. The slow arc surface of the pushing body 23 can provide a milder stirring effect to prevent the raw materials from being damaged. This setting solves the problem that the stirring mechanism in the existing mixing device can usually only meet one of the effects, thereby causing inconvenience in use.

[0024] Both sides of the outer wall of the pusher 23 are fixedly connected with a fixed frame 24, and the interior of the fixed frame 24 is inserted and fixedly connected with a diverter blade 25, which is arranged obliquely. Through this arrangement, the raw materials can be transitioned and guided, further improving the mixing effect.

[0025] The top of the pusher 23 is fixedly connected with a second fixed plate 20, and a bearing member 19 is fixedly connected between the inner side of the second fixed plate 20 and the outer wall of the rotating shaft 5. A pair of first buffer springs 30 are fixedly connected between one side of the outer wall of the pressure plate 28 and the inner wall of the pusher 23. A plurality of second buffer springs 31 are fixedly connected between the end of the plug plate 27 and the inner wall of the pusher 23. Evenly distributed pulling springs 32 are fixedly connected between the outer walls of the plug plate 27 and the pusher 23. A counterweight is provided at the bottom of the pusher 23 to increase its weight, which can prevent the rotating shaft 5 from directly driving the pusher after cooperating with the bearing member 19. 23 rotates, when the connecting arm 21 drives the plug plate 27 to pull inside the pushing body 23, the pulling spring piece 32, the second buffer spring piece 31 and the first buffer spring piece 30 can form an elastic pulling on the plug plate 27 through their own elastic deformation, so that the connecting arm 21 and the pushing body 23 are in a movable fixed state, and then when the cutting body 22 or the pushing body 23 contacts the raw material, a buffering effect is provided for it, and the resistance effect directly acting on the cutting body 22, the pushing body 23 and the plug plate 27 is reduced, so that the connection and cooperation between them have a higher bearing strength, so that it can have a longer service life.

[0026] The top of the inner wall of the mixing tank 1 is rotatably connected to a first fixed plate 7, and the bottom of the first fixed plate 7 is fixedly connected to a spiral blade 6. This arrangement can divide the raw materials and further improve the mixing effect.

[0027] The inner side of the first fixed plate 7 is fixedly connected with an outer shaft body 8, the inner side of the outer shaft body 8 is installed with an inner shaft body 9, a gear transmission assembly is arranged between the inner shaft body 9 and the rotating shaft 5, the top of the inner shaft body 9 is fixedly connected with a locking ring 10, the top of the outer shaft body 8 is fixedly connected with an L plate 14, the top of the L plate 14 is slidably connected with a slide plate 15, one side of the slide plate 15 is rotatably connected with a sliding ball 16, and the sliding ball 16 is in contact with the locking ring 10, the tops of the L plate 14 and the slide plate 15 are fixedly connected with a pull plate 17, and an adjusting screw 18 is inserted and rotatably connected to one side of the outer wall of the pull plate 17 located at the top of the L plate 14, and the adjusting screw 18 is inserted and screwed to the outer wall of the pull plate 17 located at the top of the slide plate 15. In the initial state, with the cooperation of the outer shaft body 8 and the inner shaft body 9, the rotation of the rotating shaft 5 affects the first fixed plate 7. At this time, the spiral blade 6 is in a stationary state. The rotating pull plate 17 makes the slide plate 15 approach one side of the L plate 14, and accordingly makes the sliding ball 16 tightly against the inner side of the locking ring 10, thereby forming a locking state for the outer shaft body 8 and the inner shaft body 9, so that the outer shaft body 8 and the inner shaft body 9 are locked. Therefore, at this time, the rotating shaft 5 can drive the spiral blade 6 to rotate together and then cooperate with the pushing body 23 and the cutting body 22 to further enhance the mixing effect.

[0028] The gear transmission assembly includes a first gear 11 fixedly connected to the outer wall of the rotating shaft 5, an inner gear ring 12 is fixedly connected to the inner side of the inner shaft body 9, and a uniformly distributed second gear 13 is arranged between the inner gear ring 12 and the first gear 11. The second gear 13 is inserted and rotatably connected to the bottom of the cover 4 through an axis, and the second gear 13 is respectively meshed with the first gear 11 and the inner gear ring 12. Through this arrangement, the torque provided by the rotating shaft 5 is converted into a torsion in the opposite direction to make the spiral blade 6 rotate in the opposite direction to the pushing body 23 and the cutting body 22, and the two form a cross, which further improves the mixing efficiency of the raw materials.

[0029] Working principle:

[0030] The motor 3 can drive the pushing body 23 and the cutting body 22 to stir the raw materials inside the mixing tank 1 in different rotation directions. The cutting body 22 can provide a strong shear force to accelerate the mixing effect, and the pushing body 23 provides a gentler stirring effect to avoid breaking up the materials and damaging it. The connecting arm 21, the cutting body 22 and the pushing body 23 are in a movable state under the pulling formed by the first buffer spring 30, the second buffer spring 31 and the pulling spring 32, thereby offsetting the resistance brought by the stirring materials. During the process, the spiral blade 6 can be adjusted to rotate by adjusting the adjusting screw 18. When the spiral blade 6 rotates, it can cooperate with the cutting body 22 and the pushing body 23 to further enhance the mixing effect. Under the rotation of the first gear 11 and other structures, its rotation direction is always opposite to the cutting body 22 and the pushing body 23, forming a cross rotation, which further enhances the mixing effect of the raw materials.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
