Sludge submersible mixer

Equipment Introduction

ZL-QJBThe Type submersible mixer was successfully developed by introducing German submersible motor sealing technology. After years of practical exploration, the overall performance of the submersible mixer has reached the level of similar foreign products due to its innovation in form, structure, and testing methods.

QJBtypeSludge submersible mixerIt can be divided into two main series: mixed stirring and low-speed push flow.

The mixing series mixer is suitable for mixing liquids containing suspended solids in sewage treatment plants and industrial processes;

The low-speed push flow series mixer is suitable for aeration tanks in industrial and urban sewage treatment plants. It produces strong water flow with low tangential flow, which can be used for circulation, nitrification, denitrification, and phosphorus removal stages to create water flow.

Performance characteristics:

1Compact structure, easy operation and maintenance, convenient installation and maintenance, long service life;

2The impeller has a high-quality hydraulic design structure, high working efficiency, and the swept back blades have self-cleaning function, which can prevent debris entanglement and blockage;

3Mixing with the aeration system can significantly reduce energy consumption, increase oxygen filling capacity, and effectively prevent sedimentation;

4Insulation level of motor windingFGrade, protection level isIP68Choose high-quality bearings and motors to prevent condensation Device to make the operation of the motor safer;

5Two mechanical seals;

Scope of Application

The mixer can operate continuously under the following conditions:

1.High medium temperature not exceeding40℃

2.The medium'sPHvalue in5~9between

3.Liquid density not exceeding1150kg/m3

4.Long term diving operation, with a diving depth generally not exceeding20m.

Selection precautions:

The selection of a submersible mixer is a complex task, and the correctness of the selection 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, which can generally be determined by the flow rate. According to the different process requirements of sewage treatment plants, the flow rate of the mixer should be ensured to be within0.15~0.3m/sbetween,if below0.15m/sThe flow rate cannot achieve the effect of pushing and stirring,exceed0.3m/sThe flow rate will affect the process effect and cause waste. So before selecting, first determine the location where the submersible mixer will be used, such as sewage tanks, sludge tanks, and biochemical tanks; Next are the parameters of the medium, such as suspended solids content, viscosity, temperaturePHValue; Also, the shape and depth of the pool.

The required matching power of the mixer is determined by the volume, density of the mixed liquid, and mixing depth, and one or more mixers are used according to the specific situation.

Equipment parameters and selection:

ZL-QJBBefore selecting a submersible mixer, it is necessary to first clarify the structure of the water body, the size of the pool, and the parameters of the medium. If the model you choose is notHongyuRecommended by the company, it may lead to poor equipment performance.

ZL-QJBInstallation and precautions of submersible mixer:

Key precautions:

The submersible mixer must work underwater; Cannot work in environments with flammable, explosive, or highly corrosive liquids; The steel expansion bolt must be fixed as required, and after installation, the cable must be tightened and fixed securely.

When selecting a submersible thruster, if the blade diameter exceeds2MIt is recommended to use a gearbox reducer.
