As we all know, in today's industrial age, stirring equipment is widely used in various fields and industries as an important modern industrial component. So, do you know what precautions need to be taken before and after using stirring equipment? Today, we will briefly introduce its related knowledge.
Top-entry center stirring
As a common installation method for industrial mixer agitators, it is recognized as a relatively ideal installation method for industrial mixer agitators to be inserted from the top of the container for mechanical operation and design principles. This installation makes the industrial stirrer perpendicular to the middle of the container in a straight line, and symmetric relative to the surroundings. The stirring shaft operates vertically downward due to gravity, running relatively balanced and stable, with little influence from vibration. It can also effectively avoid the contamination and accumulation of stirring material in the enclosed connection part and prolong the service life of the seal.
Side-entry stirring
According to its installation position, side-entry mixer agitators are generally installed above the side wall of the equipment cylinder, and the length of the stirrer extension and installation height is about 1-1.5 times the blade diameter, with a tilt angle and side angle between 7° and 15°. In practical applications, side-entry mixer agitators mostly adopt axial flow design, and the use of propelling type is the main selection for the stirrer. The main advantage of side-entry stirring is that it can avoid sedimentation of stirring material, and the power consumption is about 1/3 to 2/3 of top-entry industrial mixer agitators for stirring the same kind of material. Side-entry stirring is widely used in desulfurization, denitrification, storage tanks, biogas fermentation, papermaking, and stirring processes of oil materials such as crude oil and asphalt.
Tilt-type stirring
The stirrer is installed at the edge of the tank, fixed to the container edge with a clamp or chuck, and the stirring shaft is obliquely inserted into the container for stirring. It is suitable for stirring containers with a relatively simple cylindrical structure or square open mixing equipment and can prevent vortex flow. This type of stirring equipment is more flexible, convenient to use and maintain, with a simple and lightweight structure. It is generally used on small equipment, with a power of 0.1-2.2 kW, a design of 1-2 layers of blades, and a speed of 36-300 r/min.
When using for the first time, first check whether the instrument and its accompanying accessories are complete and meet the standards according to the instructions of the instrument and equipment.
When adjusting the speed, follow the method of gradually increasing from low to high speed. Do not start directly in high-speed mode unless there are special circumstances, to avoid jumping caused by the asynchronous initial speed of the industrial mixer agitator.
Do not heat when not stirring, and cut off the power supply in non-working state to avoid the industrial mixer agitator running empty.
The equipment should be kept dry and clean, and pay special attention not to let the solution enter the machine.
If jumping or non-stirring phenomenon is found during stirring, immediately shut down the machine and check.
Keep the industrial mixer agitator running at medium speed during daily operation to extend its service life.
Ground the equipment circuit to prevent static electricity.
