Detailed Description
In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.
Example 1:
As shown in fig. 1, the utility model discloses a PTA refined crystallization kettle stirrer, which comprises a kettle body 1 and a stirring shaft 3, wherein the kettle body 1 is arranged on a frame 2, a motor 4 and a speed reducer 5 are arranged on the frame 2, the motor 4 is in transmission connection with the speed reducer 5, and the speed reducer 5 is in transmission connection with the stirring shaft 3 through a coupler 6; the stirring shaft 3 extends to the inside of the kettle body 1 from the bottom of the kettle body 1, a hub 7 is arranged at the end part of the stirring shaft 3 inside the kettle body 1, the hub 7 is of a hollow cylindrical structure, a plurality of lugs 8 are arranged on the circumferential outer surface of the hub 7 at intervals, a blade 9 is fixed on each lug 8 through a connecting bolt, the blade 9 forms an included angle with a vertical plane, and the angle at the upper end of the outer side of the blade 9 is bent downwards.
The end part of the stirring shaft 3 is sleeved with a hub 7, an ear plate 8 on the hub 7 is connected through welding, a certain included angle exists between the ear plate 8 and a vertical plane, and under normal conditions, the upper end of the ear plate 8 is positioned in front of the rotation direction of the stirring shaft 3. The whole blade 9 is flat, so that an included angle is formed between the whole blade 9 and the vertical plane. The angle of the upper end of the outer side of the blade 9 is bent downwards, so that the angle between the part of the upper end of the outer side of the blade 9 and the vertical plane is slightly larger than the angle between the whole blade 9 and the vertical plane. The paddle 9 of this kind of form is under motor 4 and the drive of speed reducer 5, realize stirring the inside liquid of cauldron body 1, and stirring in-process liquid can receive radial effort and two parts axial decurrent effort, and the size of two parts axial effort is different, and liquid can the undercut extrusion in the stirring process to make the liquid of (mixing) shaft 3 bottom can receive the extrusion, outwards circulate along cauldron body 1 diapire, finally let the liquid in the cauldron body 1 realize radial, axial synchronous circulation stirring, can effectively avoid the particulate matter in the liquid to deposit in the bottom of the cauldron body 1, the mobility of liquid in the cauldron body 1 is better, and relate to each position, promoted the stirring effect to the liquid.
The stirrer of above-mentioned scheme can promote the axial pumping capacity in the stirring process, has promoted the suspension ability of liquid particulate matter, simultaneously, and the stirrer provides comprehensive axial and radial pumping capacity, can promote the liquid velocity of flow, and the knot wall material on the inner wall of the cauldron body 1 in the PTA crystallization process is continuously erodeed, avoids the material to pile up constantly and produces the bulk material, so can reduce the bulk material and drop and cause the condition emergence of destruction to paddle 9.
The hub 7 is sleeved at the end part of the stirring shaft 3 and is fixed through the gland 10 and the locking bolt 11. Since the paddle 9 generates an axial downward force on the liquid in the rotation process, the liquid generates an axial upward force on the paddle 9, so that the gland 10 and the locking bolt 11 are adopted to fix the hub 7 on the end part of the stirring shaft 3, the gland 10 can be fixed on the end part of the stirring shaft 3 by the locking bolt 11, and the gland 10 can limit the hub 7 on the stirring shaft 3 to avoid falling off due to external force.
The stirring shaft 3 passes through the equipment flange 12 and the mounting flange 13, and the equipment flange 12 is in sealing connection with the stirring shaft 3.
The frame 2 is connected with the kettle body 1 through the mounting flange 13 and the equipment flange 12, and the connection is simple and convenient, firm and stable. The stirring shaft 3 and the equipment flange 12 are sealed, and the sealing can be realized by adopting filler sealing, so that the stirring shaft 3 is always sealed with the equipment flange 12 in the rotating process, and the sealing performance is good.
