Shandong Baijiarun Chemical Equipment Co.,Ltd

Top-entry mixer is a common industrial mixing equipment, which is widely used in chemical, petroleum, pharmaceutical, food, water treatment and other industries. Its stirring shaft is inserted vertically from the top of the vessel, which is suitable for large storage tanks, reactors and other occasions that require efficient mixing, suspension, heat transfer or reaction.

Features of top-entry agitators:
Structurally stable:

It is composed of a motor, a reducer, a stirring shaft and an impeller, which is installed on the top of the container and has a stable support, which is suitable for large-capacity stirring.

Strong applicability:

It can handle high-viscosity liquids, suspensions, emulsions, etc., and is suitable for various mixing needs (mixing, dissolving, dispersing, heat transfer, etc.).

Good sealing:

Mechanical or packing seals are used to prevent liquid leakage, especially in corrosive, flammable and explosive or high-pressure environments.

Easy to maintain:

The motor and gear unit are located outside the tank for easy access and replacement of parts.

Main application areas
Chemical industry: reactor mixing, polymerization reaction, dissolution stirring, etc.

Oil/Energy: Tank mixing, asphalt mixing, slurry treatment, etc.

Pharmaceutical/Food: fermenters, ingredient mixing, emulsification, etc.

Environmental protection/water treatment: sewage treatment, flocculation stirring, chemical dissolution, etc.

Top entry agitator vs. side entry agitator
Compare top-entry agitators and side-entry agitators
Installation: Installed vertically from the top of the tank Installed horizontally from the side of the tank
Applicable tank type: large vertical storage tank, reactor, long horizontal storage tank, pipeline mixing
Stirring effect Suitable for medium and high viscosity liquids, mixing evenly Suitable for low viscosity liquids, strong local mixing
Difficulty of maintenance Convenient (motor on the outside) Complex (need to remove side panels)
The cost is higher (support structure required) is lower
How do I choose the right top-entry agitator?
Determine the purpose of agitation (mixing, suspension, heat transfer, reaction, etc.).

Consider the characteristics of the material (viscosity, corrosivity, presence or absence of solid particles).

Select the motor power (according to the tank size and agitation intensity).

Sealing method (mechanical seal is suitable for high-pressure/corrosive media, packing sealing cost is low).

Impeller type (paddle, turbine, pusher, etc., affecting mixing efficiency).
