Basic introduction of QJB submersible mixer waste water low speed plug flow device fertilizer manure Tank Mixer

Product introduction

QJB submersible mixer is one of the key equipment in water treatment process. In the water treatment process, it can achieve the requirements of homogenization and flow of solid-liquid two-phase flow and solid-liquid gas three-phase flow in biochemical process. It consists of submersible motor, impeller and installation system. The submersible mixer is of direct connection structure. Compared with the traditional high-power motor, it has the advantages of compact structure, low energy consumption and easy maintenance. Impeller after investment casting or stamping forming, high precision, push large, flow linear, simple and beautiful shape. This series of products are suitable for the place where solid-liquid mixing and mixing are needed.

Product features

Two sets of independent mechanical seals ensure the long-term and reliable operation of submersible motor

High quality imported one-time lubrication bearing, design service life 8000 hours

The unique cable sealing design eliminates the hidden danger of cable leakage. Cable protection device, so that it is not cut by the impeller

Many years of production of submersible motor technology, the end does not use sealant, so that the submersible motor operation more reliable

Stainless steel, carbon steel investment casting welding impeller, after optimization design, the blade is swept back, high efficiency, with self-cleaning function

The motor shaft is made of stainless steel, and the rotor runs smoothly after dynamic balance test

It can be equipped with leakage sensor and stator winding overtemperature protection alarm device (option)

Special tips: the submersible mixer must be completely submerged to work, and can not work in flammable, explosive, highly corrosive and high temperature environment. According to the requirements of special environment, our company can provide special design for users.

Table of performance parameters and type selection of submersible mixer

The selection of submersible mixer is a complex work. The correctness of the selection scheme directly affects the normal use of the equipment. As the principle of selection, the mixer should give full play to the mixing function in a suitable volume. This standard can be determined by the flow rate. According to different process requirements of sewage treatment plant, the best flow rate of mixer selection should be between 0.15 and 0.3m/s. If the flow rate is lower than 0.15m/s, the effect of plug flow mixing can not be achieved. If the flow rate is higher than 0.3m/s, the process effect will be affected and waste will be caused. Therefore, before selecting the type, it is necessary to first determine where the submersible mixer is used, such as sewage tank, sludge tank or biochemical tank; secondly, the medium parameters, such as suspended solids content, temperature, pH value, etc.; and the shape, water depth and even installation mode of the tank will have an impact on the type selection, which should also be considered To the energy saving factor, because it will affect the user's future operating costs. Refer to the flow field diagram of submersible mixer below.
