Du'an Equipment Jiangsu Co., Ltd. provides you with the Du'an GSJ/QSJ type hyperbolic mixer.

Du'an GSJ/QSJ type hyperbolic mixer

Model: G/QSJ-2500

Power: 3--5.5kW

Speed: 20--40r/min

Impeller diameter: 2500mm

I. Application Range

The GSJ/QSJ series hyperbolic mixer is a product developed by our company. It is widely used in industries such as chemical, energy, and light industry for solid, liquid, and gas exchange in liquids. It is particularly suitable for mixing and blending in coagulation tanks, regulation tanks, anaerobic tanks, aeration tanks, nitrification and denitrification tanks in wastewater treatment processes, as well as for mixing and blending various abrasive and high-temperature media.

II. Structure Introduction

The hyperbolic mixer can be divided into two types based on the installation method: GDJ type (dry type) and QDJ type (submersible type).

The GSJ type hyperbolic mixer consists of a geared motor, vibration damping seat, mixing shaft, hyperbolic impeller, electrical control box, and bridge frame (can be provided by the user). The QDJ type hyperbolic mixer consists of a frame, lifting steel cable, main unit, hyperbolic impeller, and electrical control box.

III. Transportation and Storage

1. During transportation, the mixing shaft and impeller must not be subjected to pressure or collision. Use lifting equipment for loading and unloading, and prevent scratches on the impeller surface.

2. For long-term storage, avoid high temperature and high humidity environments. The mixing shaft should be hung vertically, and the impeller should be placed on a flat surface to prevent deformation.

IV. Installation

GDJ Series Installation Steps

1. The bridge frame should be leveled, and the bridge frame columns should be vertically aligned. Anchor bolts and connection parts should be secure.

2. Place the vibration damping seat on the designated position of the bridge frame, level it, and then fix it to the bridge frame.

3. Install the geared motor on the vibration damping seat and secure it.

4. Connect and tighten the impeller and mixing shaft flange with bolts.

5. Place the impeller and mixing shaft into the tank, connect the mixing shaft to the output shaft of the geared motor, and tighten. If there is water, first connect the shaft and impeller and place them in the water, then connect the shaft to the geared motor.

6. After installation, the mixing shaft must be perpendicular to the horizontal plane. The vertical deviation should be less than 1/1000.

7. After installation, remove the motor rear cover and manually rotate the fan blades to check if the mixer rotates smoothly and normally. The mixing shaft swing deviation should be less than 3/1000.

8. After connecting the power supply, briefly start the mixer to observe the rotation direction of the mixing shaft. The correct rotation direction, when viewed from above, is counterclockwise. If not, swap any two power supply wires.

9. Electrical equipment installation must comply with relevant regulations and safety procedures.

QDJ Series Installation Steps

1. Briefly start the mixer on land to observe the rotation direction of the impeller. The correct rotation direction, when viewed from above, is counterclockwise. If not, swap any two power supply wires.

2. Separate and secure the motor cable and lifting cable. Do not bundle the cable and steel rope together. Prevent the steel rope and cable from being entangled in the impeller.

3. Use a crane to lift the hyperbolic mixer and slowly lower it to the designated position in the tank, taking care not to hit the tank wall.

4. Secure one end of the fixing rope to the bank, and connect the cable to the electrical control cabinet.

V. Operation

After installation, the equipment must undergo a trial run. Before the trial run, fill the tank with approximately 70% of its volume with water. Do not operate the equipment without water, as it may cause uneven force on the mixing shaft and lead to bending. After the trial run, check the following:

1. Whether there are any abnormal noises or temperature rise in the geared motor.

2. Whether the motor current is within the rated range (a short-term overcurrent during startup is normal).

3. The swing condition of the mixing shaft.

4. Whether there are any debris in the tank.

If any abnormal conditions are observed in the above aspects, identify the cause and rectify it before use.

VI. Maintenance

1. For new machines, replace the gearbox lubricating oil after 200-300 hours of operation and clean internal oil sludge. Thereafter, replace it every six months to a year. For details on the use of the geared motor, refer to the manufacturer's operation and maintenance manual.

2. Regularly check whether the mixing shaft lock nut and various connecting bolts are loose.

3. Regularly check the swing condition of the mixing shaft and promptly remove any entanglements on the impeller and shaft.

4. Regularly check for abnormal noises and temperature rise in rotating parts.

5. Regularly check for abnormal changes in current.

6. Before restarting the equipment after a long period of inactivity, check the motor's insulation. Also, prevent sediment accumulation over time, which may cause difficulty in starting and damage the motor and impeller.

7. Keep records of the above inspections. If any abnormalities occur, contact our company.
