Product Definition
The Side-Entry Mixer is an industrial mixing equipment that mounts the mixing unit on the side wall of a container (tank, trough, or pool). Its mixing shaft extends horizontally or at an inclined angle into the container, and the rotation of the mixing assembly achieves process requirements such as material mixing, homogenization, suspension, and heat transfer. Unlike the vertical installation of top-entry mixers, it is more suitable for large-volume containers or scenarios with limited top space, serving as one of the core equipment for fluid treatment in industrial production.
Structural Composition
The overall structure of the Side-Entry Mixer consists of four core parts: the drive unit, transmission connection, mixing working part, and sealing protection system. All components work in coordination to ensure the stable operation of the equipment, with the specific composition as follows:
Drive Unit:
It is mainly composed of a motor and a reducer. The motor can be an ordinary motor or an explosion-proof motor, customized according to working conditions to provide stable power for the equipment. The reducer adopts cycloid pinwheel or gearbox transmission to achieve stable power transmission and speed regulation.
Transmission Connection:
A pulley or pin coupling is usually used to connect the drive unit and the mixing shaft. Some models adopt a direct transmission method to reduce power loss, ensure the stable rotation speed of the mixing shaft, and meet the mixing speed requirements of different processes.
Mixing Working Part:
It includes the mixing shaft, agitator, and frame. The mixing shaft is supported by bidirectional thrust bearings and water-lubricated sliding bearings, with sufficient strength and rigidity, and its length can be customized according to the container size. The agitator is mostly of the axial flow type, mainly propeller-type, and some scenarios can be equipped with propeller-type and paddle-type blades to act directly on materials. The frame is made of high-quality carbon steel plates and channel steel through welding, used to fix the equipment and ensure stability during operation.
Core Performance Parameters and Advantages
Core Performance Parameters
Mixing Volume:
It has a wide adaptation range, suitable for containers with a volume of tens of cubic meters to 210,000 cubic meters, meeting the mixing needs of small storage tanks to large industrial storage tanks.
Speed Range:
200-750r/min, which can be flexibly adjusted according to material characteristics and process requirements.
Power Consumption:
Under the same mixing effect, the power consumption is only 1/3 to 2/3 of that of top-entry mixers, with significant energy-saving advantages.
Adaptable Materials:
It can handle materials with a maximum viscosity of 1000cp and a maximum density of 1.5, including pure liquids, solid-liquid mixtures, liquid-liquid mixtures, etc., adapting to various working conditions.
Core Advantages
Energy Saving and Economy:
Under the same mixing effect, it consumes less energy than top-entry mixers, and the equipment purchase cost is only 1/4 to 1/3 of that of top-entry mixers, which can significantly reduce production costs during long-term operation.
Flexible Installation:
Adopting horizontal or inclined installation, it can avoid pipelines and equipment on the top of the container, suitable for scenarios with limited top space. The installation angle can be adjusted between 0° and 30°, and one equipment can meet the mixing needs of large-volume containers.
Convenient Maintenance:
Key components such as the drive unit and sealing assembly are installed outside the container. Daily inspection, maintenance, and component replacement do not require emptying the container, and can be operated online, shortening downtime and reducing maintenance costs.
Efficient Mixing:
Adopting axial flow agitator, it can achieve better mixing effect under the same power, quickly realize material homogenization, prevent precipitation, and improve process efficiency. Some models can eliminate mixing dead angles through fluid simulation design to ensure uniform mixing.
Application Fields
With its large-volume adaptability and flexible installation method, the equipment is widely used in multiple industrial fields, with core application scenarios as follows:
Petrochemical Industry:
Used for homogeneous mixing of large crude oil storage tanks, product oil tanks, and raw material oil storage tanks to prevent material stratification and precipitation. In chemical reactions such as polymerization, sulfonation, and esterification, it provides appropriate circulation and shear to strengthen mass and heat transfer and improve reaction efficiency.
Environmental Protection and Water Treatment:
Applied in large aeration tanks, anaerobic tanks, neutralization tanks, etc., to promote the full mixing of activated sludge, sewage, and chemicals, prevent sludge precipitation, and improve biochemical treatment efficiency. It is used in sludge storage tanks and concentration tanks to maintain sludge fluidity and facilitate subsequent dehydration treatment.
Food and Pharmaceutical Industry:
Used for the storage and mixing of materials such as fruit juice, syrup, and liquid medicine to maintain uniform composition. In large fermenters, it is equipped with sterile shaft seals to achieve gentle mixing, ensuring uniform distribution of bacteria, nutrients, and dissolved oxygen, meeting GMP requirements.
Maintenance and Operation Points
Daily Maintenance
Regularly check the sealing system, focus on the wear of mechanical seals or packing seals, replace seals in a timely manner to prevent material leakage. For equipment handling corrosive materials, increase the frequency of seal inspections.
Check the wear and deformation of the mixing blades, especially when handling materials containing solid particles. Regularly clean the attachments on the blades, and replace the blades if necessary to ensure mixing effect.
Regularly add lubricating oil to the reducer and motor of the drive unit, check the oil level and quality, avoid overheating or wear of components, and extend the service life of the equipment.
Check the tightness of fixed components such as the frame and bolts to prevent vibration and loosening during equipment operation and avoid component damage.
Operation Points
Before starting the equipment, check whether the mixing shaft and agitator are flexible and the sealing system is intact. Start the motor only after confirmation to avoid idling or load starting.
Adjust the mixing speed according to material characteristics and process requirements, avoid excessive speed leading to material splashing or increased energy consumption, and insufficient speed affecting mixing effect.
During the operation of the equipment, observe the operation status in real time. If abnormal noise, vibration, leakage, or other conditions occur, stop the machine immediately for inspection, and resume operation after troubleshooting.
When shutting down for a long time, clean the residual materials in the container, clean and maintain components such as the agitator and seals to prevent residual materials from corroding the equipment.
