Dry powder dosing device

1、 Product Introduction
The dry powder dosing device is an intelligent, fully automatic, continuous integrated flocculant dissolution and dosing device, with a solution preparation range of 0-4000 liters/hour and a concentration of 0.1% -0.5%. This device consists of a water supply system, a dry powder feeding system, a dissolution and maturation system, a control system, a liquid feeding system, and a secondary dilution feeding system. This device is a fully automatic continuous configuration and dosing system for powdered (or liquid) polymer flocculants. The dry powder flocculant enters the pre mixer from the screw propeller and is pre mixed with clean water. The moistened material enters the preparation tank for dilution and is prepared according to the required concentration; If it is a liquid flocculant, it is directly added to the preparation tank by a screw pump. During the preparation process, if there is a change in water volume, the flocculant dosing device will automatically follow the change in water flow rate to ensure that the concentration of the prepared solution remains unchanged throughout the entire working process. The prepared solution enters the storage tank after passing through the maturation tank. When the liquid level in the storage tank is at a high level, the preparation process automatically stops. When the solution drops to a medium level, the batching process is automatically restarted. Both the preparation tank and the maturation tank are equipped with multi blade agitators to fully ensure the dilution and maturation of the flocculant. In addition, the liquid level signal under the storage tank can be used to control the start and stop of the secondary dilution and dosing process. This device is a control system composed of basic units such as a PLC controller, a Chinese human-machine dialogue interface, and a microcontroller, which are integrated into a servo proportional controller. It has a high degree of automation, stable performance, reliable operation, intuitive Chinese human-machine interface, menu operation, and is simple and clear.
The automatic dissolution and dosing device for flocculants consists of the following parts: water supply system, dry powder dosing system, liquid agent dosing system, dry powder pre mixing system, integrated three tank combination box mixing system, automatic control and detection system.
2、 Product Features
High degree of automation, the system is controlled by PLC and adopts a Chinese human-machine dialogue interface. Operate and display the operating status of each unit on the interface, with an intuitive human-machine interface, simple and convenient to operate. The system is stable and reliable. In the event of a malfunction, the relevant equipment will automatically stop as required and sound an audible and visual alarm. The powder is fed using a double helix feeder with closed-loop speed control to ensure uniform, dispersed, and accurate feeding within 1%. Under the specified production volume and continuous liquid feeding conditions, the maturation time of the prepared solution is guaranteed to be at least 1 hour. Its preparation concentration is 0.05% -0.5%. Made of stainless steel material, it has good corrosion resistance and is aesthetically pleasing. Adopting a three tank overflow solution operating system makes the equipment structure simple, small in size, and easy to install. Suitable for the process flow of dissolving and continuously adding chemicals. The mixer adopts a specially designed multi-stage blade structure. The premix accelerates the hydration of the powder, and the water flow state can be adjusted. The amount of dry powder added automatically follows the changes in water flow rate to maintain a constant concentration.
