The manufacturer of the dosing device explains the selection method of the dosing mixer in detail

 

The dosing mixer is an important part of the dosing device. It is responsible for mixing the agent to be added evenly to improve the effect of the agent and reduce the amount of agent used. Therefore, it is very important to select the dosing mixer. Based on years of experience, the dosing device manufacturer Hechuang Environmental Protection summarized the selection method of the dosing mixer to help you achieve low-cost dosing treatment.

Dosing mixers are mostly found in automatic dosing devices, which are used for wet dosing of water treatment. They can continuously and automatically disperse and dilute and control the amount of dry powder agents, so that flocculants can be rapidly dissolved and prepared into a uniform solution of a certain concentration. They are highly stable and economical. The dosing device of Hechuang Environmental Protection is controlled by PLC, and the dosing mixer is controlled by PLC. The equipment runs automatically throughout the process without manual intervention, so the quality requirements for the dosing mixer are relatively high. To ensure the normal operation of the equipment, you can select the dosing mixer according to the following methods.

1. The constant speed or variable frequency dosing mixer shall be selected according to the demand;

2. The dosing mixers of different materials shall be selected according to the characteristics of chemicals;

3. The dosing mixer with screw propelling blades or two blade flat blades shall be selected as required;

4. The dosing mixers with different mixing power shall be selected according to the reagent ratio;

Dosing device equipped with dosing mixer

The manufacturer of the dosing device prompts that according to the above selection method, you can meet your purchasing needs for the dosing mixer. In addition, the mixer is the key mechanical equipment in the dosing device, and its installation quality directly affects the operation of the device. Due to the installation quality problems of the mixer of some devices, the mechanical seal leaks, the equipment runs unstably, and the vibration and swing are obvious, resulting in serious consequences. General installation steps of mixer: (1) equipment unpacking inspection; (2) Recheck the levelness of the installation flange seat; (3) Installation of mixing shaft; (4) Installation of mixer base (including seal and bearing); (5) Installation of mixing impeller; (6) Installation of gearbox; (7) Motor installation; (8) Recheck the swing of the mixing shaft; (9) Adjust and fix the bottom bearing bracket; (10) Installation of sealing system; (11) Installation of other accessories.
