one. Uses and Features
Side entry mixers are widely used in environmental protection, biogas fermentation, desulfurization in power plants, large petrochemical storage tanks, papermaking, construction and other industries, which can achieve good heat transfer, uniform mixing and effectively prevent deposition and other functions. It has the characteristics of low investment, low power consumption, high stirring efficiency and convenient operation.
two. The main structure of the side entry mixer
Barrel Side Entry Mixer
Dual Pivot Rack Side Entry Mixer
Side entry mixers have a variety of structural forms in the market. The company mainly produces two structural forms, one is a barrel-type inner and outer shaft structure mixer and a rack-type mixer. The two types of mixers are based on different customer process application environments. The transmission is driven by the pulley; the sealing can adopt various sealing forms according to the different use environments of customers, such as mechanical seals, packing seals, labyrinth seals and other forms; different sealing forms can also be used in combination; such as : The sealing form of the 2000m3 starch finished product tank adopts the combined sealing form of mechanical seal and packing;
1. The main mechanism of the barrel type side entry mixer:
The whole is mainly composed of motor, pulley, motor bracket, outer shaft, reinforcement, mounting flange, inner shaft, mechanical seal, impeller, bearing and other components. There is a set of sealing systems at both ends of the inner shaft. Generally, mechanical seals are used. Small tanks or customers with low requirements also have water seals at both ends;
2. Double fulcrum rack side entry mixer
Relatively simple structure, mainly composed of motor, pulley, double fulcrum frame, stirring shaft, mounting flange, a set of mechanical seal, impeller and other components.
three. Engineering Applications
Biogas fermentation: Stir the fermentation raw materials and biogas microorganisms to make them fully mixed and evenly contacted so that the microorganisms can have sufficient food, ensure normal fermentation, and increase the gas production rate. Prevent the raw materials from being divided into clean shells and precipitation.
Flue gas desulfurization: In desulfurization, it is mainly used in large vessels such as slurry tanks and absorption towers to stir the slurry in the tower to prevent the precipitation of the suspension, and at the same time fully mix the blown oxidizing gas and the paddle.
Others: large crude oil storage tanks, pulp and paper, lubricating oil storage tanks, edible oil storage tanks, etc.
This device is used for large-scale reaction tanks and storage tanks to mix and stir the medium and prevent sedimentation. The device adopts three types of sealing, which are safe and reliable. The working pressure is 0~1.0MPa, and the working temperature is -10~100℃. The transmission shaft adopts special The structural design makes it easy to replace the wearing parts such as mechanical seals and bearings without disassembling the whole machine.
The side entry mixer is to install the mixing device on the side wall of the equipment barrel. The mixer on the mixer usually adopts the axial flow type, and the propeller mixer is mostly used. The mixing effect that can be obtained under the condition of the same power consumption, The power consumption is only 1/3 to 2/3 of the top stirring, and the cost is only 1/4 to 1/3 of the top stirring. The speed can be 200 ~ 750r/min.
It is used for desulfurization, denitration and agitation of various large storage tanks or storage tanks. Especially in large storage tanks or storage tanks, one or more side-entry mixers can be used to work together, and a good mixing effect can be obtained under the condition of low energy consumption.
1. Purpose: This device is used for large-scale reaction tanks and storage tanks to mix and stir the medium. Installed on the wall of the tank, generally 2-4 sets are set along the periphery, the agitator is a propeller, and the axis direction can be horizontal or inclined.
Use temperature: 0-50℃, use pressure: normal pressure -0.3MPa,
Stirring speed: 300r/min, medium: weakly corrosive organic solvent, non-flammable and explosive medium.
2. Features: The device adopts three sealing forms, which are safe and reliable:
a, 212 type bellows type single-end mechanical seal is the main seal;
b. Stop seal, when the main seal is replaced, the stirring shaft stops transmission, and the stop seal works to prevent the leakage of the medium in the tank;
c. The impeller is sealed to prevent solid particles and crystals in the medium from entering the main seal for protection. The drive shaft on the frame of the device can be pulled out, and it is extremely convenient to replace the mechanical seal at the square hole of the frame.
