Drifter Submersible Mixer

Product Introduction

FQJB type floating drum submersible mixer is a new generation of mixing equipment designed and developed for some large and deep square or circular pools. On the basis of summarizing the existing sewage mixing equipment at home and abroad, the product structure and performance are innovated. In particular, on the basis of the propulsion mixer, the horizontal structure is creatively changed to a vertical circulation mechanism, making it more distinctive in terms of overall structure, technical performance, mixing efficiency, service area, applicability, etc. It has the advantages of long service life, low noise, convenient installation and maintenance, low investment, and low operating costs.
 

This instruction manual includes some regulations that should be followed in terms of product installation, commissioning, operation, maintenance, etc. Before operating the equipment, please read and master the relevant regulations carefully and clarify the following issues:
1. Whether the model and specifications of the product are compatible with the occasion;
2. Whether the model of the control cabinet equipped matches the host;
3. According to user needs, terminal boxes can be equipped. Please determine the specific model;
4. Whether the complete set supply and spare parts are consistent with the contract.

FQJB vertical buoy submersible mixer uses a large-displacement propeller-type propulsion impeller as the main hydraulic component. During operation, the submersible motor drives the propulsion impeller to work, so that the fluid generates flow velocity, and sprays and diffuses around at an angle at the bottom of the pool to form an annular mainstream belt. Because the flow velocity of the mainstream belt is relatively large, a turbulent area with it as the center is formed around it, which prompts the water in the entire pool to form a large cycle of up and down turbulence, thereby realizing large-area three-dimensional circulation stirring, so that the sludge in the pool is always in a state of turbulence and suspension, increasing the contact surface of the material phase, eliminating the stirring dead corner, achieving the purpose of uniform and gentle stirring, ensuring a good anaerobic treatment effect, and improving the treatment effect.

FQJB buoy submersible mixers can be divided into medium-high speed mixing series and high-speed mixing series according to different use occasions:

1. The medium-high speed mixing series of buoy submersible mixers has a relatively high speed and a relatively small service range, but the mixing is relatively gentle, and can be used in anaerobic or anoxic treatment of sewage treatment plants;

2. The high-speed plug-flow mixing series of buoy submersible mixers has a low speed, a large service range, high hydraulic efficiency, and uniform mixing. It can be used in regulating tanks of various sewage treatment projects, and can also be used in anaerobic or anoxic tanks.

1. The buoy-type submersible mixer has a large turbulent area, a wide action area, gentle and uniform mixing, and can effectively reduce or even clean up the mixing dead corners, without damaging the flocculent structure and bacterial flocs of the activated sludge;
2. The water flow of the buoy-type submersible mixer adopts a large circulation flow scheme, which fully mixes the sludge. It is suitable for a water depth of 2~9m and a radiation area of ​​100~800 square meters;
3. The power of the buoy-type submersible mixer is a submersible motor, which is coaxial with the mixer. When used, it works underwater. It not only has good cooling conditions and a wide range of applicable depths, but also does not produce secondary pollution such as noise; the mechatronic structure can reduce mechanical losses and improve unit efficiency;
4. The main seal of the submersible motor of the buoy-type submersible mixer is a two-way series mechanical seal, and a multi-way auxiliary sealing system is also used to ensure the reliability of the motor seal;
5. The submersible motor of the buoy-type submersible mixer is equipped with multiple alarm protection systems such as oil leakage, stator overtemperature, phase loss, short circuit, etc., making the product more safe to use. , reliable;
6. The buoy submersible mixer is easy and flexible to install. It can be installed in a variety of ways. When floating installation is adopted, there is no need to build a professional factory and construct an installation platform. The comprehensive investment is low, and it is easy to install, use and maintain;
7. The buoy submersible mixer is not limited by the pool type and volume. It can be one pool with one machine or multiple machines. The number can be increased or decreased at any time according to the process requirements, and the installation position can be moved at any time. It can be centrally controlled automatically or run alone, which is very convenient to manage.

 Model Description

Medium and High Speed ​​Floating Drum Submersible Mixer
1. Annular Channel
When the Floating Drum Submersible Mixer is in operation, the water flow driven by the impeller is distributed through the guide of the annular channel, and is sprayed and diffused at an angle to the bottom of the pool in a 360° direction, driving the sludge to slowly flip and rise, increasing the contact surface of the material phase and eliminating the mixing dead corner.
2. Guide Cylinder
The Floating Drum Submersible Mixer guides the fluid from the impeller to the annular channel, and at the same time forms a water flow scheme with water inlet and outlet from the top, so that the water in the entire pool forms a large cycle of up and down flipping.
3. Impeller
The Floating Drum Submersible Mixer uses large-displacement linear propulsion technology, which can produce strong propulsion and stirring functions when rotating.
4. Trash Rack
The Floating Drum Submersible Mixer prevents the entry of plastic bags, metal wires, firewood sticks, packaging tapes and other debris in the sewage, avoiding entanglement, damage to the impeller, and affecting the normal operation of the equipment.
5. Submersible motor
The insulation grade of the submersible motor of the buoy submersible mixer is F-class, the main shaft is made of stainless steel, and the rotor parts have passed the dynamic balance test; the imported bearings are equipped with high-temperature resistant grease, low noise and long life; the main seal is composed of two sets of mechanical seals in series, and is equipped with imported wide lip oil seals and "O" rings and other auxiliary seals, which have dynamic and static sealing effects. The motor is also equipped with stator overtemperature protection and oil leakage protection and other protection systems.
6. Installing sleeve
The buoy submersible mixer can make full use of the performance of the mixer by adjusting the height of the installation sleeve according to user needs and process requirements.

Installation method of buoy submersible mixer: According to the process requirements and the actual situation on site, users can choose the installation method of the mixer.

Main installation method
Fixed installation is divided into platform installation and pool bottom installation

a. Platform installation Build an installation platform, and directly install the main unit on the platform for fixing. This installation method is suitable for fixed water level occasions.

b. Pool bottom installation (currently only suitable for medium and high speed mixers). Place the mixer directly on the bottom of the pool, connect one end of the steel wire to the main unit, and fix the other end to the pool wall. The advantage of this method is that it does not affect the overall aesthetics and has a low investment cost. But it can only be used on hard pool bottoms.
