[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 4 , the present invention discloses a speed-adjusting stirrer for platinum catalyst production, including a positioning and clamping base 10. The top surface of the positioning and clamping base 10 is welded with a lifting device 20. The lifting end of the lifting device 20 is bolted with an extension plate 30 on the front. The top surface of the extension plate 30 is bolted with a motor 40 and a variable frequency speed regulator 50. The bottom of the motor 40 is drivingly connected with a stirring rod 60. A plurality of vertically equally spaced openings 70 are provided on one side of the lifting device 20. A limiting mechanism 80 is clamped on one of the openings 70. One side of the lifting end of the lifting device 20 is integrally connected with a convex plate 90.

[0022] In this implementation, the lifting device 20 adopts a screw rod and bevel gear structure, which is manually adjustable and can drive the motor 40, the variable frequency speed regulator 50, and the stirring rod 60 to move up and down together, so as to fully stir the platinum catalyst raw materials. The variable frequency speed regulator 50 can be used in cooperation with the motor 40 to stably adjust the rotation speed of the stirring rod 60, playing a role in speed adjustment.

[0023] Specifically, the limiting mechanism 80 includes a long block 81. A stud 82 is provided on the top surface of the long block 81 and is threadedly connected thereto. A support platform 83 is integrally connected to the top end of the stud 82. A first knob 84 is welded to the bottom end of the stud 82. Long grooves 85 are formed on both the front and rear sides of the long block 81. Two L-shaped clamping bars 86 are provided in the two long grooves 85 and are slidably connected to the front and rear thereof. On the side of the two L-shaped clamping bars 86 close to each other, a plurality of springs 87 are welded. Each spring 87 is welded to the inner wall of the long groove 85. The long block 81 is inserted into the opening 70. The L-shaped clamping bar 86 is clamped on the inner wall of one side of the lifting device 20. The support platform 83 is of a disc structure and is located directly below the convex plate 90.

[0024] In this embodiment, according to the horizontal height of the inner wall of the lower part of the material bucket, the two L-shaped clamping bars 86 are squeezed. The springs 87 elastically contract, and the L-shaped clamping bars 86 are all received in the long grooves 85. The entire long block 81 is inserted into the opening 70 at an appropriate height. The L-shaped clamping bars 86 are released. Under the elastic force of the springs 87, the two L-shaped clamping bars 86 move away from each other and are clamped. The lifting device 20 drives the stirring rod 60 to move downward, and the dispersion disc stirring impeller on the stirring rod 60 is brought into contact with the inner wall of the lower part of the material bucket. Then, the lifting device 20 drives the dispersion disc stirring impeller to move slightly upward. The first knob 84 is rotated forward, and the stud 82 rotates forward and moves upward until the top surface of the support platform 83 is in contact with the bottom surface of the convex plate 90, so as to achieve limit adjustment and prevent damage to the dispersion disc stirring impeller during subsequent use.

[0025] Specifically, the positioning and clamping base 10 includes a bottom plate 11. A cavity is formed in the bottom plate 11. Four long openings 12 are formed on the top surface of the bottom plate 11. A screw rod 13 is rotatably connected to the front and rear inner walls of the cavity. The screw rod 13 is threadedly connected to a pair of moving strips 14 that are slidably connected to the front and rear of the cavity. Convex columns 15 are integrally connected to the top surfaces of the two moving strips 14. A mold 16 is placed on the top surface of the bottom plate 11. Four round holes 17 are formed on the top surface of the mold 16. The convex columns 15 are inserted into the round holes 17. A second knob 100 welded to the front end of the screw rod 13 is provided in the middle of the front surface of the positioning and clamping base 10. The screw rod 13 is a left-right threaded rod.

[0026] In this embodiment, the mold 16 is placed above the bottom plate 11, and the convex columns 15 are clamped in the round holes 17, so as to achieve the positioning and clamping of the mold 16. Then, the second knob 100 can be rotated reversely by a wrench, and the screw rod 13 rotates reversely accordingly. The two moving strips 14 move away from each other, and the two pairs of convex columns 15 move away from each other and tightly press against the inner wall of the round hole 17, so as to tighten the mold 16. The replacement of the mold 16 is fast, and there will be no phenomenon of position deviation. During subsequent use, the material bucket can be directly clamped on the mold 16, and the material bucket is stable during stirring.
