QJBAs one of the key equipment in water treatment processes, the submersible mixer can achieve the process requirements of homogenization and flow of solid-liquid two-phase flow and solid-liquid gas three-phase flow in the biochemical process. It consists of a submersible motor, impeller, and installation system. The submersible mixer is a direct coupled structure. Compared with traditional high-power motors that reduce speed through reducers, it has the advantages of compact structure, low energy consumption, and easy maintenance. The impeller is precision cast or stamped, with high precision, high thrust, and a simple and beautiful linear shape. This series of products is suitable for places that require solid-liquid mixing and blending. The structural diagram is as follows.

Application scope:

Submersible mixers are mainly used for mixing, stirring, and circulating in municipal and industrial wastewater treatment processes. They can also be used as maintenance equipment for scenic water environments, creating water flow through stirring, improving water quality, increasing oxygen content in water, and effectively preventing suspended solids deposition.

Usage conditions:

To ensure the normal operation of the submersible mixer, please choose the correct working environment and operating mode.
The maximum medium temperature shall not exceed40℃；
mediumpHValue range:5~9；
The medium density does not exceed1150Kg/m3;
Diving depth not exceeding20m.

Special Notice:

The submersible mixer must work completely submerged in water and cannot operate in flammable, explosive, highly corrosive, or high-temperature environments. Our company can provide special designs for users to meet the requirements of special environments.

performance parameters:

The submersible mixer operates at a rated voltage of380ambush,frequency is50HzThe performance parameters are shown in the following table:

Note:1In the mixing and stirring series in the table above, the value marked in the "weight" column is the weight including the guide cover;

2Insulation level of motor winding:FGrade, protection level:IP68Motor working mode:24Working continuously for hours.

Selection reference:

The selection of a submersible mixer is a complex task, and the correctness of the selection plan directly affects the normal use of the equipment. As a principle of selection, it is necessary to ensure that the mixer can fully perform its mixing function within the suitable volume. This standard can generally be determined by the flow rate. According to the different process requirements of sewage treatment plants, the optimal flow rate of the mixer selection should ensure that it is within0.15~0.3m/sBetween, if lower than0.15m/sIf the flow rate exceeds, it cannot achieve the effect of pushing and stirring0.3m/sThe flow rate will affect the process effect and cause waste. So before selecting, the first thing to determine is where the submersible mixer will be used, such as in a sewage tank, sludge tank, or biochemical tank; Next are medium parameters, such as suspended solids content, temperaturePHValue, etc; The shape, depth, and installation method of the pool will also have an impact on the selection, and energy-saving factors should also be considered, as this will affect the user's future operating costs. You can refer to the flow field diagram of the submersible mixer below.

In order to achieve the best mixing function in different environments, we provide users with multiple models of submersible mixers and offer selection services

Installation method and size:

There are multiple installation methods for submersible mixers, and here are four of the most common methods to choose from. The dimensions can refer to the table below. Our company can also make special designs according to user requirements.

Note:1The specialized installation system for submersible mixers allows for quick installation and disassembly without the need to discharge sewage from the pool;
2Install the systemI-1Only applicable to pool depth<4mThe model isQJBO.85／8andQJBl.5／6, and can adjust the angle in both horizontal and vertical directions; When the pool is deep>4mWhen installing, the installation system should be selectedI-2Type.
3Install the systemIITheIIIThe guide rod can rotate around the axis of the guide rod in the horizontal direction, with a maximum angle of ±60°；
4WhenH>4mWhen necessary, add a support frame in the middle of the guide rod;
5The support frame and lower bracket are fixed to the pool wall and bottom with expansion bolts or chemical anchor bolts, without the need for reserved holes;

operation mode:6When the customer places an order, please provide the depth of the poolHAnd the pool diagram, in order to determine the size of the guide rod and the number of support frames;
7Stainless steel and carbon steel anti-corrosion materials are available for installation of the system;
8Multiple mixers can share a lifting system.

The installation and positioning of the submersible mixer have a significant impact on its mixing effect. In order to achieve twice the result with half the effort, we recommend that users follow the requirements of professional designers, fully considering the shape of the pool, the position of the inlet and outlet water, and the vortex caused by the reflection of the mixer's water flow to the structure, in order to minimize the occurrence of short circuit circulation and dead corners, and avoid collision with the pool wall to reduce the flow rate. Referring to the operating mode diagram below can help you choose the mixer and installation form reasonably.
