Automatic Chemical-feed Device

Automatic Dosing Device
Human water shortage, water treatment technologies to promote the development of pharmaceutical dosing is commonly used in water treatment engineering technical measures. However, many water treatment engineering, pharmaceutical equipment, due to the backwardness of dosing, resulting in cumbersome manual operation, high-value chemicals waste, or even affect the efficiency of enterprises.
Category: coagulant (flocculant) Dosing devices, corrosion inhibitor (inhibitor) dosing device to regulate the PH value added acid (alkali) devices, such as water treatment dosing equipment.
Performance characteristics: the amount of accurate dosing, constant. Dosing capacity, wide scope of application. Easy to operate, simple to administer. Pharmaceutical dosage easy to adjust.
Coagulant (flocculant) Dosing Device
Process Principle
Natural waters contain a certain amount of colloidal particles, their electrostatic repulsion and Brown under the effect of thermal motion to overcome the influence of gravity to maintain dynamic balance and will not gather precipitation, thereby affecting the turbidity of the water target. Commonly used method is to remove the colloidal particles in water investment and increasing the height of charged ions, or polymer material, the use of electrical neutralization, adsorption and bridges, and other principles of netting so that colloidal particles off steady, cohesion precipitation, so that water clarification.
Commonly used coagulant (flocculant), including aluminum salts, iron salts and the corresponding polymers, etc..
Process Overview
This device includes liquid solvent distribution systems, metering dosing systems, security systems and control systems in four parts.
Solid pharmaceutical medicine chest within the accession to dissolve, and then join the industrial water mixing ratio of dissolved dosing by measuring the system point of investment and added to the dosage. Dosing control can be used manually, but also based on the charge detector or swimming in the upper system output control signals to servo control, automatic dosing.
Scope of application: Municipal water supply, wastewater treatment, thermal pretreatment of raw water, wastewater treatment.
Corrosion inhibitor (inhibitor) Dosing Device
Process Principle

Process Overview
This device includes liquid solvent distribution systems, metering dosing systems, security systems and control systems in four parts.
Solid pharmaceutical medicine chest within the accession to dissolve, and then join the industrial water mixing ratio of dissolved dosing by measuring the system point of investment and added to the dosage. Dosing control can be used manually, but also based on the control of the upper system output signal, for servo control, automatic dosing.
Scope
Thermal power plant or oil cooling loop water treatment chemicals.
Adjust PH value added acid (alkali) devices
Process Principle
As the water treatment process requirements, the PH value of water is often need to be controlled within a certain range, to water, acid or alkali dosing manual is to meet this demand the most direct and effective approach. Commonly used acid and alkali neutralizer, including sulfuric acid, hydrochloric acid, ammonia, calcium hydroxide, sodium hydroxide, sodium carbonate and so on.
Process Overview
This device includes liquid solvent distribution systems, metering dosing systems, security systems and control systems in four parts.
Solid pharmaceutical medicine chest within the accession to dissolve, and then join the industrial water mixing ratio of dissolved dosing by measuring the system point of investment and added to the dosage; liquid pharmaceutical generally not diluted with water, direct dosing. Dosing control can be used manually, but also based on the control of the upper system output signal, for servo control, automatic dosing.
