Description

Technical Field

[0001] The utility model relates to the technical field of propeller mixers, and more specifically, to a propeller mixer. Background Art

[0002] A propeller mixer is a device used for gas-liquid mixing reactions. It uses a powerful motor to precisely and stably stir high-viscosity liquids at a relatively high speed. The folding-blade impeller can mix the liquid very well. It is an essential tool in the fields of petroleum, chemical industry, metallurgy, textile, food, medicine, sanitation, environmental protection, biochemical laboratories, analysis rooms, education and scientific research, etc.

[0003] For example, a propulsion mixer proposed in the announcement number CN212283611U includes a fixed seat; the top of the fixed seat is fixedly connected to a support frame, a first inner groove is provided on the inner side of the support frame, a second inner groove is provided on the inner side of the support frame away from the first inner groove, and the second inner groove is symmetrically arranged with the first inner groove. The first screw and the second screw will respectively drive the first gear and the second gear in the first inner groove and the third gear and the fourth gear in the second inner groove to rotate while rotating, so that the four fixing screws are gradually turned into the screw holes of the installation position, so that the fixed seat and the support frame can be quickly and stably installed in the required position. When it is necessary to stir the mixed liquid in the dosing reaction device, the driving motor drives the propeller-type stirring rod to rotate at a high speed. Since the stirring rod is a propeller-type setting, its driving force is relatively large, so that the discharge volume of the mixer is increased, the circulation capacity is enhanced, and the power consumption is reduced.

[0004] The above patent has the following defects during use:

The scope of application is small and the practicality is poor. Therefore, there is an urgent need to improve the technology of the propeller mixer to improve this equipment.

[0006] Therefore, the utility model proposes a propeller mixer. Utility Model Content

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0029] Example:

[0030] See also Figure 1-6 A propulsion mixer comprises a mounting plate 1, a mounting frame 2 is fixedly connected to the upper end of the mounting plate 1, and a fixing device 3 is installed between the mounting plate 1 and the mounting frame 2, a rotating sleeve 5 is rotatably connected between the mounting plate 1 and the mounting frame 2, and its lower end is opened, a motor 4 is installed at the upper end of the mounting frame 2, and the output end of the motor 4 is connected to the upper end of the rotating sleeve 5, a movable stirring rod 6 is arranged inside the rotating sleeve 5, and a telescopic adjustment mechanism 7 is installed between the movable stirring rod 6 and the rotating sleeve 5, the lower end of the movable stirring rod 6 passes through the lower end opening of the rotating sleeve 5 and extends to the lower side thereof, the outer end of the movable stirring rod 6 is sleeved with a connecting sleeve 8, and a connecting assembly 10 is installed between the movable stirring rod 6 and the connecting sleeve 8, and a plurality of spiral blades 9 are fixedly connected to the outer end of the connecting sleeve 8.

[0031] During use of the present solution, the pusher mixer is first moved into the mixing container to be used, and then, according to the depth of the mixing container, the pair of electric telescopic rods 704 of the telescopic adjustment mechanism 7 are driven to retract, so that the pair of clamping plates 705 are separated from the movable stirring rod 6, and the clamping fixation thereof is cancelled. Then, the telescopic cylinder 701 pushes the sliding plate 702 to move downward, so that it drives the movable stirring rod 6 and the connecting sleeve 8 to extend downward, and at the same time, the displacement sensor 703 records the extension data of the sliding plate 702 and the movable stirring rod 6 in real time. When the movable stirring rod 6 and the connecting sleeve 8 extend downward to match the depth of the mixing container, the movement is stopped, and then the pair of electric telescopic rods 704 are extended toward each other, driving the pair of clamping plates 705 to clamp and fix the movable stirring rod 6, so as to achieve the ability to move when facing mixing containers of different depths. Carry out corresponding adjustment to expand its scope of use and improve its practicality. After the adjustment is completed, the moving pusher mixer is installed on the mixing container through the fixing device 3, so that the movable stirring rod 6 and the connecting sleeve 8 are deeply inserted into the mixing container. After the various raw materials in the mixing container are added, the motor 4 works to drive the rotating sleeve 5 and the movable stirring rod 6 to rotate, so that it drives the connecting sleeve 8 and the multiple spiral blades 9 to rotate, and the various raw materials are mixed and stirred. When the spiral blades 9 are damaged during multiple uses, the multiple locking screws 1001 in the operating connection assembly 10 are rotated outward to separate from the threaded fixing groove 1002, loosen the fixation between the movable stirring rod 6 and the connecting sleeve 8, and drive the damaged spiral blades 9 to be disassembled, so that the staff can replace the spiral blades 9, thereby facilitating subsequent use.

[0032] See also Figure 2-4 The telescopic adjustment mechanism 7 includes a telescopic cylinder 701 installed on the top end of the rotating sleeve 5, and a sliding plate 702 is slidably connected to the inside of the rotating sleeve 5, and the upper and lower ends of the sliding plate 702 are respectively connected to the output end of the telescopic cylinder 701 and the upper end of the movable stirring rod 6, and a displacement sensor 703 is embedded in the sliding plate 702. A pair of electric telescopic rods 704 are embedded in the inner wall of the rotating sleeve 5, and the ends of the pair of electric telescopic rods 704 that are close to each other are fixedly connected with a clamping plate 705, and the pair of clamping plates 705 are in contact with the outer end of the movable stirring rod 6.

[0033] During use of the present solution, when facing stirring containers of different depths, a pair of electric telescopic rods 704 first pulls a pair of clamps 705 to move away from each other, separates from the movable stirring rod 6, and cancels the clamping and fixing thereof, and then the telescopic cylinder 701 pushes the sliding plate 702 to move downward, so that it drives the movable stirring rod 6 and the connecting sleeve 8 to extend downward, and at the same time, the displacement sensor 703 records the extension data of the sliding plate 702 and the movable stirring rod 6 in real time, and when the movable stirring rod 6 and the connecting sleeve 8 extend downward to match the depth of the stirring container, the movement is stopped, and then the pair of electric telescopic rods 704 extend toward each other, driving the pair of clamps 705 to clamp and fix the movable stirring rod 6, so that corresponding adjustments can be made when facing stirring containers of different depths, thereby expanding its scope of use and improving its practicality.

[0034] See also Figure 4 The outer ends of a pair of clamping plates 705 are both arc-shaped.

[0035] During use of the present invention, the arc-shaped clamping plate 705 can better fit the movable stirring rod 6 when clamping and fixing it, so that the clamping and fixing is more complete and comprehensive.

[0036] See also Figure 2-3 A sealing ring 501 is fixedly connected to the inner wall of the lower end opening of the rotating sleeve 5 , and the inner wall of the sealing ring 501 is in close contact with the outer end of the movable stirring rod 6 .

[0037] During use of the present solution, the sealing ring 501 is provided to prevent liquid from easily penetrating into the rotating sleeve 5 through the gap between the lower end opening of the rotating sleeve 5 and the movable stirring rod 6, thereby improving the sealing performance.

[0038] See also Figure 1 and Figure 5-6 The connecting assembly 10 includes a plurality of locking screws 1001 threadedly connected to the connecting sleeve 8, a plurality of threaded fixing grooves 1002 are formed on the outer end of the movable stirring rod 6, and the locking screws 1001 are threadedly connected to the threaded fixing grooves 1002.

[0039] During use of the present solution, the spiral blades 9 are often damaged after being used for a long time and multiple times. At this time, multiple locking screws 1001 are operated to rotate outward in sequence, separate from multiple threaded fixing grooves 1002 respectively, loosen the fixation between the movable stirring rod 6 and the connecting sleeve 8, and drive the damaged spiral blades 9 to be disassembled, so that the staff can replace the spiral blades 9, thereby facilitating subsequent use.
