The dosing device is based on metering pump as the main dosing equipment, which assembles the dosing box, mixer, level gauge, safety valve, check valve, pressure gauge,
filter, buffer, pipeline, valve, base, escalator, automatic monitoring system and power control system on a
common platform according to the process requirements, forming a module, namely the so-called
skid-mounted combined unit
The dosing device is based on metering pump as the main dosing equipment, which assembles the dosing box, mixer, level gauge, safety valve, check valve, pressure gauge, filter, buffer, pipeline, valve, base, escalator, automatic monitoring system and power control system on a common platform according to the process requirements, forming a module, namely the so-called skid-mounted combined unit (abbreviated as skid-mounted combined unit). "Pry body". Quantitative dosage can be put into the mixing solution box to mix and dissolve as needed. After dissolution, the dosage can be freely adjusted to meet different dosage places by metering pump to the dosing point. Mechatronics structure is adopted, which can be divided into fixed type and mobile type (trolley type) from installation. Each type of dosing device is equipped with mixing system, dosing system and automatic control system. Several fixed pry-ups can be combined into a whole. With frequency conversion control system, local control, remote automatic control, manual and automatic reciprocal dosing can be realized. The utility model has the advantages of compact structure, small volume, low noise, stable operation, simple installation and convenient operation.

Through different process design, the dosing device accurately configures the solutions of various solid and liquid chemicals, and then accurately feeds them with metering pumps to meet various design requirements. Such as scale removal, oxygen removal, coagulation, acid addition, alkali addition, etc.

The dosing process can be operated manually, and the dosing device can be automatically controlled by means of various electrical appliances such as PC, magnetic tilting plate level gauge, PH meter, stroke controller, frequency converter and so on.

The dosing quantity and pressure of the dosing device can be selected according to the needs of industrial process. The flow rate ranges from 1 L/h to 8 000 L/h, and the pressure ranges from 0.1 MPa to 25 MPa.

The metering accuracy of the metering pump can be as high as (+1%) and it can realize the simultaneous transmission of various mediums and adjust them individually.

The volume of the solution box in the dosing device can be from 0.1 M3 to 20 m3. It can be selected according to the dosing amount. According to the different medium, there are many materials to choose, such as carbon steel (carbon steel lining), stainless steel, non-metallic materials (PE, PVC, PP, PTFE), etc.
