INTRODUCTION

The chemical storage tank is usually made of corrosion-resistant materials such as polyethylene or stainless steel. It can safely store various liquid chemicals, effectively preventing chemical reactions between the chemicals and the tank, ensuring the stability of the chemical properties. Moreover, it has a variety of capacity specifications and can be flexibly selected according to the actual dosing requirements. The metering pump, as the core dosing power component, has a high-precision flow adjustment function and can accurately output the corresponding dose of chemicals according to the preset parameters. The control system is like the "brain" of the device. It monitors relevant parameters such as water level, flow rate, and water quality in real-time through sensors and then precisely controls the operation of the metering pumps based on the preset program logic to realize automated and intelligent dosing operations. Pipelines and valves are responsible for the transportation and flow direction control of chemicals, ensuring that the chemicals can reach the designated dosing points smoothly.

This equipment is widely used in many fields such as water treatment, chemical industry, and food processing. It can be adapted to a variety of different types of chemicals and has the advantages of simple operation, precise dosing, and stable and reliable operation. It is an important helper for ensuring the stability of the production process and meeting the water quality standards.

WORKING PRINCIPLE

The working principle of automatic dosing devices focuses on precise measurement and intelligent control. Firstly, the required chemicals are added to the chemical storage tank for storage. After the equipment is started, the control system will make comprehensive judgments based on the preset parameters and the information fed back in real-time by the sensors.

For example, in a water treatment scenario, if the sensors detect that the concentration of a certain pollutant in the water is too high or the pH value of the water body deviates from the set range, the control system will send instructions to the metering pumps, driving the metering pumps to extract the chemicals from the chemical storage tank according to the corresponding flow requirements and transport them through pipelines to the corresponding dosing points and accurately add them to the water body to be treated. During this process, the metering pumps rely on their own precise adjustment mechanisms to accurately control the output amount of chemicals each time, ensuring that the dosing amount of chemicals matches the actual demand. Meanwhile, as the chemicals are added, the sensors will continuously monitor the changes in relevant parameters of the water body. Once the parameters reach the set standard range, the control system will promptly adjust the operating state of the metering pumps, suspend or reduce the dosing of chemicals. This cycle repeats, keeping the entire dosing process always in a precisely controlled state and ensuring that the treatment effect meets the expected goals.

MAIN PERFORMANCE AND CHARACTERISTICS

l Precise Dosing: Thanks to the high-precision metering pumps and the advanced control system, it can achieve precise control over the dosing amount of chemicals. Whether it is the addition of trace amounts of chemicals or the dosing of larger doses, it can be accurate to a very small error range, effectively avoiding the impact on the treatment effect due to excessive or insufficient dosing. Especially in industries such as water treatment and pharmaceuticals where strict requirements for chemical doses are imposed, it can fully meet the needs of refined production processes.

l High Degree of Automation: Equipped with a complete control system, it can automatically collect various monitoring data and independently determine the operating state of the metering pumps according to the preset rules and algorithms. There is no need for manual monitoring all the time and manual adjustment, which greatly saves labor costs and also reduces the uncertainties caused by human operation errors. It ensures that the entire dosing process is stable, efficient, and accurate and can maintain a stable operating state for a long time, ensuring the continuity of production operations.

l Strong Adaptability: It can be adapted to various chemicals with different properties and concentrations. Whether they are acidic or alkaline chemical agents or chemicals with special biological activities, accurate dosing can be achieved by reasonably adjusting the equipment parameters. Moreover, it can be applied to different industry fields and treatment scenarios, such as sewage treatment, industrial circulating water quality adjustment, and disinfection and sterilization in food processing. It only needs simple configuration according to specific requirements before it can be put into use. It has good versatility and can meet diverse dosing requirements.

l Safe and Reliable: From the selection of materials for the chemical storage tank to the overall electrical design, safety factors have been fully considered. It has good functions such as leak prevention, corrosion prevention, and overload protection, effectively reducing safety risks caused by chemical leakage and equipment failures, ensuring the personal safety of operators and the safety of the surrounding environment. Meanwhile, the overall structure of the equipment is stable, the key components are of reliable quality, and it is not prone to malfunctions during operation, and the maintenance cost is also relatively low.

l Simple Operation: The operation interface of the equipment is simple and clear. Operators only need to set some basic parameters when using it for the first time, such as the type of chemicals, the dosing amount range, and monitoring indicators. During the subsequent daily operation, they can simply check the operating state of the equipment. Ordinary personnel can master the operation method proficiently after a brief training, facilitating its quick deployment in various places and improving work efficiency.

APPLICATION FIELDS AND INDUSTRIES

l Water Treatment Field: In municipal sewage treatment, automatic dosing devices can accurately add flocculants, disinfectants, and other chemicals according to the water quality of the sewage to help remove suspended solids in the sewage and kill harmful bacteria, ensuring that the sewage meets the discharge standards. In industrial wastewater treatment, for the complex wastewater generated by different industries, such as chemical wastewater and electroplating wastewater, by accurately adding corresponding neutralizing agents, heavy metal scavengers, and other chemicals, the pH value of the wastewater can be adjusted and heavy metal ions can be removed, enabling the wastewater to meet the requirements of subsequent treatment or discharge standards and protecting the ecological environment. Meanwhile, in industrial circulating water systems, the addition of corrosion inhibitors and scale inhibitors can effectively prevent the scaling and corrosion of pipes and equipment, extend the service life of the equipment, and ensure the normal operation of production.

l Chemical Industry: The chemical production process involves numerous chemical reactions, which require strict control of the addition amount and addition time of various chemical agents. Automatic dosing devices can accurately add catalysts, initiators, reactants, and other chemicals according to the process requirements, ensuring that chemical reactions proceed at the predetermined rate and direction, improving product quality, ensuring the stability and safety of the production process, and helping chemical enterprises achieve efficient and precise production.

l Food Processing Industry: Food processing has extremely high requirements for hygiene and safety. This device can be used to accurately add disinfectants, preservatives, and other chemicals. While ensuring food quality and safety, it strictly controls the residual amount of chemicals to meet food hygiene standards, avoiding harm to human health caused by excessive use of chemicals, providing consumers with safe food products, and maintaining a good corporate image.
