2. Characteristics, structure, and working process of Jiangsu Du'an Environmental Protection ZJ type dosing mixer
2.1 Characteristics
a) The ZJ-500 folding paddle mixer and paddle mixer have a large reduction ratio and high efficiency: the first stage transmission reduction ratio is 9-87, the two-stage transmission reduction ratio is 121-7569, and the multi-stage combination can reach tens of thousands. In addition, the needle tooth joint system has a sleeve type rolling friction, and there is no relative sliding on the tooth joint surface, so the first stage reduction efficiency reaches 94%.
b) Operating for civilian use, with low noise, multiple teeth in contact during operation, high overlap, smooth operation, strong overload capacity, low vibration and noise, and noise levels below 85db (A) for various specifications of models.
c) Reliable in use and with a long lifespan, the main components are made of high carbon alloy steel through quenching treatment (hrc58-62), which is finely ground. When the cycloidal teeth and needle teeth are transmitted to the needle teeth to form rolling friction, the friction coefficient is small, resulting in no relative sliding in the meshing area and minimal wear, making it durable and long-lasting.
d) Compact structure, small footprint, large processing capacity, and low energy consumption; Small in size, compared to other gearboxes of the same power, the important size is more than one-third smaller. Due to planetary rotation, the input shaft and output shaft are on the same axis to achieve the smallest possible size.
e) Low installation, operation, and maintenance costs;
2.2 Construction and Working Process
The ZJ-500 folding paddle mixer and vertical mixer (as shown in the figure) are mainly composed of a reducer, frame, coupling, mixing shaft, paddle board, etc.
After the paddle board rotates, the chemicals added to the pool are fully dissolved, and the molecules of the chemicals react quickly with harmful substances in the sewage, achieving efficient disinfection and decontamination effects.
The Jiangsu Du'an Environmental Protection ZJ-500 folding paddle mixer consists of an electric motor, a vertical reducer, a frame, a coupling, a main shaft, a slurry plate, and underwater bearings. When the electric motor is powered on and decelerated by the reducer, the torque is transmitted to the main shaft of the mixer through the coupling to drive the slurry plate to rotate, thereby stirring the liquid.

Detailed information of ZJ-500 folding paddle mixer
Overview of ZJ-500 folding paddle mixer:
The ZJ-500 folding blade mixer has a simple structure. The blades are made of flat steel and welded or fixed to the hub with bolts. The number of blades is 2, 3 or 4, and the blade form can be divided into two types: flat blade and folding blade. According to the shape characteristics of the blades, it can be divided into flat blade mixer and inclined blade mixer. The flat blade agitator generates radial force, while the inclined blade agitator generates axial force. The blade agitator is suitable for stirring low viscosity liquids, suspensions, and dissolved liquids.
ZJ-500 folding paddle mixer mixer Purpose:
The folding paddle mixer is a common mixing equipment for preparing coagulant, coagulant aid, disinfectant and lime lotion in water supply and drainage engineering.
Stirrer blade turningAt 45 degrees, the liquid flow generates axial diversion and circumferential swirl. The whole machine adopts a motor-driven cycloidal pinwheel reducer for direct transmission, with a simple and compact structure, installed in the center of the water tank, smooth operation, and high dissolution efficiency.
Design and manufacturing selection steps:
The design and shape of the paddle mixer should be closely related to the purpose of the mixing operation. Different mixing processes require different mixers to be implemented. When designing and selecting, the mixer type, motor power, mixing speed, and sealing form should be determined based on the purpose and requirements of the mixing operation according to the working conditions. Then, various components such as reducer, frame, mixing shaft, and shaft seal should be selected.
The specific steps and methods are as follows:
1. According to the process conditions, mixing purposes, and requirements, select the type of mixer. When selecting the type of mixer, it is necessary to fully understand the dynamic characteristics of the mixer and the causal relationship between the flow state generated by the mixer during the mixing process and various mixing purposes.
2. Determine the motor power, stirring speed, and stirrer diameter through experimental methods or computer simulation design based on the determined type of stirrer and the flow state generated by the stirrer during the stirring process, as well as the control requirements of the process for stirring and mixing time, settling speed, and dispersion.
3. Select the reducer model from the reducer selection table based on the motor power, mixing speed, and process conditions. If the gearbox is selected based on the actual working torque, the actual working torque should be less than the allowable torque of the gearbox.

1. It has a wide range of applications and can stir various liquids with different concentrations, media, and suspended solids.
2. Stable operation, low vibration, and low noise.
3. Corrosion resistant, therefore it can stir various liquids with pH 3-10.
If the equipment is not in use temporarily, it can be stored for a long time.
Precautions:
The dosing mixer needs to be installed and used correctly to ensure safe and stable long-term operation.
Installation personnel should have corresponding qualifications and be familiar with mechanical equipment installation knowledge to carry out installation work.
The dosing mixer should be installed vertically, with a vertical deviation of no more than 5 degrees.
4. It is strictly prohibited to mix solids and liquids with high viscosity in the dosing mixing system.
5. The motor and bearing temperature cannot operate above 75 ℃.
The motor, bearings, and gearbox cannot operate in the absence of lubricating oil.
7. The agitator shaft and blades cannot operate under bending or deformation conditions. If the shaft is found to be bent or the blades are deformed, the machine should be stopped immediately for processing or replacement.
During the operation of the dosing mixing system, it is strictly prohibited to allow debris to enter the reaction tank to avoid damaging the mixer shaft and blades.
If a person needs to enter the reaction tank for cleaning or maintenance operations, the motor power must be cut off and a "Do Not Close" warning sign must be hung. When conducting manual tank cleaning and maintenance operations, there must be a dedicated person outside the reaction tank to supervise.
After running for a period of time, if there are sediment, impurities, and debris at the bottom of the reaction tank in the 10 dosing mixing system, it should be stopped in time and rinsed with clean water or manually cleaned to ensure the safe operation of the mixer.
