However, in actual applications, specifically during the process of stirring the catalyst material in the reactor, it is difficult to lift the material at the bottom of the reactor to the upper end.

DETAILED DESCRIPTION
[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0027] Example:
[0028] Reference Figure 1-Figure 3 The utility model discloses a catalyst preparation reactor, comprising a stirring drum 1, a sealing cover 2 is threadedly connected to the upper end of the stirring drum 1, a rotating shaft tube 3 is arranged in the middle of the sealing cover 2, two groups of linkage mechanisms 4 are arranged on both sides of the part of the rotating shaft tube 3 inserted into the interior of the stirring drum 1, and a stirring tube 5 is commonly arranged at the ends of the two groups of linkage mechanisms 4 located on the same side of the rotating shaft tube 3, a driving mechanism 6 is arranged on the upper end of the sealing cover 2, a sealing push rod 7 is slidably connected to the interior of the rotating shaft tube 3, and a cam mechanism 8 is arranged on one side of the upper end of the sealing cover 2.
[0029] In this embodiment, when in use, the materials required for catalyst preparation are put into the mixing drum 1, and the sealing cover 2 is screwed on the upper end of the mixing drum 1. Then, the driving mechanism 6 drives the rotating shaft tube 3 to rotate, so that the linkage mechanism 4 on both sides of the rotating shaft tube 3 and the stirring tube 5 rotate inside the mixing drum 1 with the rotating shaft tube 3 as the axis, so as to achieve the effect of stirring the materials in the mixing drum 1. At the same time, the cam mechanism 8 is set to drive the sealing push rod 7 to move up and down. At this time, the air pressure inside the rotating shaft tube 3 changes continuously with the movement of the sealing push rod 7, and the linkage mechanism 4 will expand and contract with the change of the air pressure inside the rotating shaft tube 3, so that the relative position of the stirring tube 5 and the rotating shaft tube 3 changes continuously, so that the materials at the bottom end of the mixing drum 1 can be guided to the upper end by the stirring tube 5, thereby improving the uniformity and speed of stirring of the reactor.
[0030] In a further preferred embodiment of the present invention, Figure 1-3As shown, the linkage mechanism 4 includes a piston tube 41, which is fixedly connected to the rotating shaft tube 3, and the piston tube 41 is located in the mixing drum 1. The inner tube cavities of the piston tube 41 and the rotating shaft tube 3 are interconnected, and a piston push rod 42 is arranged inside the piston tube 41.
[0031] In this embodiment, when the air pressure inside the rotating shaft tube 3 changes following the movement of the sealing push rod 7, the piston push rod 42 moves inside the piston tube 41, thereby achieving the purpose of changing the straight-line distance between the stirring tube 5 fixedly connected to the piston push rod 42 and the rotating shaft tube 3, and in the process of stirring the material inside the mixing drum 1, the stirring rate is further improved.
[0032] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the stirring tube 5 includes a mounting straight tube 51, both ends of which are fixedly connected to the piston push rod 42 at corresponding positions, and a bevel tube 52 is provided at the bottom of the mounting straight tube 51. The bottom of the bevel tube 52 fits with the inner bottom end of the stirring drum 1, and the upper end of the mounting straight tube 51 is connected to a transverse extension tube 53.
[0033] In this embodiment, when the stirring tube 5 rotates inside the stirring drum 1 with the rotating shaft tube 3 as the axis, the material at the bottom end of the stirring drum 1 is scooped up by the inclined tube 52 and introduced into the interior of the installed straight tube 51, and then introduced into the interior of the transverse extension tube 53 through the inner tube cavity of the installed straight tube 51, and discharged from the transverse extension tube 53, so that the material moves directly from the bottom of the stirring drum 1 to the upper end of the interior of the stirring drum 1, so as to achieve rapid mixing of the materials at the upper and lower ends of the stirring drum 1, thereby further improving the mixing efficiency of the materials.
[0034] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the inner tube wall and the outer tube wall of the stirring tube 5 are both arc surface structures, and the upper end surface of the mounting straight tube 51 and the upper end surface of the stirring drum 1 are located in the same horizontal plane.
[0035] In this embodiment, by setting the stirring tube 5 with an arc surface structure, the material is prevented from getting stuck in the stirring tube 5 when passing through the stirring tube 5, thereby preventing the material from being contaminated in the stirring tube 5 and causing difficulty in cleaning.
[0036] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the driving mechanism 6 includes a driving motor 61 and two driving gear rings 62. The two driving gear rings 62 are respectively fixedly connected to the rotating shaft tube 3 and the driving shaft of the driving motor 61 through a coupling, and the two driving gear rings 62 are meshed.
[0037] In this embodiment, when in use, the driving motor 61 drives the two mutually meshing driving gear rings 62 to rotate, thereby causing the rotating shaft tube 3 to rotate. During the rotation of the rotating shaft tube 3, the piston tube 41 fixedly connected to the rotating shaft tube 3 rotates with the rotating shaft tube 3 as the axis.
[0038] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the cam mechanism 8 includes a rotating disk 81, a servo motor 82 and a motor bracket 83, the motor bracket 83 is fixedly connected to one side of the upper end of the sealing cover 2, the top of the motor bracket 83 is fixedly embedded with the servo motor 82, the motor shaft of the servo motor 82 is fixedly installed with a rotating disk 81, one side of the rotating disk 81 is rotatably connected with a rotating shaft 84 near the edge, the middle part of the rotating shaft 84 is sleeved with a crankshaft connecting rod 85, and the end of the crankshaft connecting rod 85 away from the rotating shaft 84 is rotatably connected with a connecting shaft 86 connected to the sealing push rod 7.
[0039] In this embodiment, the motor bracket 83 is used to install the servo motor 82. When the device is used, the servo motor 82 drives the rotating disk 81 to rotate, and then the rotating disk 81 rotates to make the crankshaft connecting rod connected to the rotation pull the connecting shaft 86 to move the sealing push rod 7 up and down, so as to achieve the effect of moving the sealing push rod 7 inside the rotating shaft tube 3, thereby changing the internal air pressure of the rotating shaft tube 3 to make the piston push rod 42 move inside the piston tube 41;
[0040] Specifically, during the rotation of the rotating disk 81, the rotating shaft 84 moves from the top to the bottom following the rotating disk 81, so that the crankshaft connecting rod pushes the sealing push rod 7 downward, so that the portion of the sealing push rod 7 inserted into the rotating shaft tube 3 becomes longer, so that the volume of the cavity inside the rotating shaft tube 3 becomes smaller, and then the pressure inside the rotating shaft tube 3 increases, so that the piston push rod 42 pushes the piston tube 41 out, and then the stirring tube 5 is away from the rotating shaft tube 3;
[0041] On the contrary, the rotating shaft 84 rotates from the bottom to the top following the rotating disk 81, so that the crankshaft connecting rod pulls the sealing push rod 7 to move upward, so that the stirring tube 5 is close to the rotating shaft tube 3;
[0042] This achieves the effect of changing the position of the stirring tube 5 inside the stirring drum 1, further achieving the effect of increasing the influence range of the stirring tube 5 on the material, and achieving the effect of improving the preparation efficiency of the catalyst.
[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
