Fully automatic potassium monopersulfate dosing device

　　Fully automatic potassium monopersulfate dosing deviceIn industries such as water treatment, chemical engineering, and printing and dyeing, it is necessary to add another solution to water or other liquids in proportion. The production process is continuous, and this addition work must also be continuous. For example, in water treatment, coagulants and disinfectants are added, and in cooling towers, scale inhibitors are added. In chemical engineering and printing and dyeing, a certain amount of chemical agents such as acid and alkali are added at regular intervals. All of these require equipment that can both prepare solutions and add chemicals in a quantitative and timed manner.

The dosing device product is a new type of chemical dosing equipment newly launched by our factory. Widely used in various dosing systems for oilfield dehydration treatment, surface gathering and transportation, pipeline demulsification, polymer injection engineering, and production processes in the petroleum, chemical, and power industries, as well as in surface wastewater treatment. It is widely used in production processes such as oily wastewater treatment and water quality treatment. Adopting an integrated mechanical and electrical structure, the installation can be divided into fixed and movable (cart type) types. Each type of dosing device is equipped with a mixing system, dosing system, and automatic control system. Several fixed wave devices can be combined as a whole, coupled with a variable frequency control system, to achieve remote control of dosing. The trolley type device is particularly suitable for multi tube dosing in a workshop, which is convenient, flexible, and cost-effective.

The dosing device has the advantages of compact structure, small volume, low noise, and stable operation, making it suitable for water treatment devices of various scales. Our factory can design and manufacture equipment suitable for users based on their on-site conditions. And provide relevant technical services.

2、 Working principle

Before adding medication, first close the drain valve 14 and all valves in the pipeline. After filling the substitute tank with medication, start the mixer start button on the control cabinet 11 to mix and stir evenly in proportion. Then open valves 5, 8, 12, and 13, and start the metering pump 7 (one for use and one for backup, or both). After running for 1-2 minutes, close the vent valve 5 (to exhaust the air in the pipeline) to deliver medication to the external pipeline normally. If only one metering pump is needed, close one of the inlet and outlet valves of ball valves 12 and 13. The two pumps should be used alternately, and filter 14 should be cleaned regularly to remove impurities. Before cleaning, ball valves 8 and 13 should be closed; If the safety valve trips due to external factors during the work process, the liquid will be automatically discharged from the safety valve to the sewage ditch. If the medicine is not dispensed from the pump, the power supply needs to be cut off for inspection.

3、 Precautions for installation operation and common troubleshooting methods

1. Check if the corner platform of the dosing device is on the same horizontal line (no need to install foot screws), and if there are threaded connectors, quick connectors, and flange connectors at the pump outlet. Connect the corresponding connectors and power supply.

2. Make preparations before operation, inject an appropriate amount of SBJ-20 and SBJ-30 mechanical oil into the metering pump box and reducer box, based on the oil level line.

3. Close the drain valve, pipeline valve, and automatically or manually add medication. Press the power button, control cabinet, and power indicator light to indicate that the power is connected. Press the mixing tank button, and the mixer will start working for 3-5 minutes. Then, open the pipeline valve and flow control valve, and press the metering pump start button to start the metering pump.

4. Regularly check whether the feed inlet of the metering pump is blocked, and clean the pipelines and filters regularly to prevent blockage.

5. Regularly inspect the mixing device to see if the mixing shaft rotates flexibly, if the impeller is twisted or deformed, if the coupling sleeve is loose, if there is excessive torque on one side, and if it consumes mixing power. If it is broken, it should be replaced in a timely manner.

6. Regularly inspect safety valves, pressure gauges, and various pipeline valves to prevent leakage incidents. When using two or more pumps for dosing, they should be used alternately to avoid starting or stopping one pump for a long time.

A series of policies such as green power certificate trading, direct trading of distributed generation, and clean heating of renewable energy have all sent positive signals to the entire industry. Previously, due to resource conditions, many wind and solar power projects were built in the northwest region of China. However, due to limited local demand, a large amount of resources could not be effectively utilized. Now this situation is quietly changing. Compared to the development model of resource-based large-scale base construction during the 12th Five Year Plan period, the overall layout of wind power construction in the 13th Five Year Plan is shifting towards the central and southern regions.

Specifically speaking of the situation of new installed capacity, in regions such as Xinjiang and Gansu where wind power curtailment is severe, the construction scale of new wind power generation projects is strictly controlled to avoid increasing the operational difficulty of existing projects, and to encourage the shift of the focus of new energy development to the central, eastern, and southern regions where wind power curtailment is not prevalent. According to operational data released by the China Electricity Council, the proportion of newly installed wind power capacity in the eastern and central regions of China has reached nearly 60% in the first half of this year.

2. The dosing device adopts an electromechanical integrated structure, which can be divided into fixed and mobile (cart type) installation. Each form of dosing device is equipped with a stirring system, dosing system, and automatic control system. Several fixed pry mounts can be combined into a whole, coupled with a variable frequency control system, which can achieve local control, remote automatic control, and manual and automatic mutual conversion of dosing. It has the advantages of compact structure, small volume, low noise, smooth operation, simple installation, and easy operation and use.

3. The dosing device is designed with different processes to prepare solutions of various solid and liquid chemicals, and then accurately added using a metering pump to meet various design requirements. Such as descaling, deoxygenation, coagulation, acid addition, alkali addition, etc.

4. The dosing process can be manually operated, or various electrical appliances and instruments such as PC, magnetic flap level gauge, pH meter, stroke controller, frequency converter, etc. can be used to make the dosing device an electromechanical integrated product and achieve automatic control.
