The fully automatic dosing device is a mechanical automatic dosing system widely used in industries such as water treatment and petrochemicals. The operation process of the fully automatic dosing device is very simple, which can be operated manually or through a controller. But before the fully automatic dosing device starts working, it is necessary to do a good job of debugging to avoid unnecessary trouble. In the process of water supply and drainage treatment, various chemical agents are often added for scale inhibition, algae removal, coagulation, and flocculation to achieve the goal of purifying water. These formulations include solid particles and liquids, which should be dissolved, diluted, and administered in proportion during the administration process to achieve good results. Therefore, the fully automatic dosing device is one of the commonly used equipment in water treatment engineering.

How to debug the fully automatic dosing device

1. Check if the water source and power supply of the fully automatic dosing device are connected.

2. Check if the fully automatic dosing device is intact, set the control button of the machine to the manual position, and check if the motor rotates correctly.

3. Use your hands to move the floating balls inside the box up and down one by one, check if the fully automatic dosing device machine can work properly, and check if the machine alarm can work properly.

4. Put the dry polyacrylamide solid powder into the hopper and place it in a suitable container at the inlet.

5. Open the inlet valve and press the start button of the feeding motor to start feeding.

6. Weigh the polymer in the container and keep a record.

7. Repeat steps 5 and 6 above and predict the average weight of the powder conveyed through the feeder.

8. Repeat the above three steps and make a record. Due to the controllable and known feed rate, a feed rate curve can be drawn for future reference.

9. Stop the feeder.

10. Set the control switch in the electrical cabinet to the "automatic" position.

11. When the liquid level reaches a high level, the feeder should be able to automatically stop, stop water intake, and start the metering pump. When the liquid level reaches a low level, the feeder should be able to automatically start feeding and adding water.

12. Adjust the stroke of the metering pump to the appropriate point and then enter automatic operation mode.

Before installation at the customer's site, it is necessary to carry out various debugging work and preparations to accelerate the dosing installation work without causing more trouble.

Precautions when selecting a fully automatic dosing device

When selecting a fully automatic dosing device, the user first determines the selection specifications based on the amount of solution added to the system (including metering pump parameters, mixing tank volume, solution tank volume, and on-site debugging), and then determines the dosing based on the dosing situation.

2. Select the materials and metering pump models for each part of the fully automatic dosing device as needed.

The bubble medicine barrel is developed by scientific formula and blown. It has various colors, beautiful appearance, acid and alkali resistance, corrosion resistance, anti-leakage, no fading, no deformation, and meets the packaging indicators. It is currently the long-distance transportation of chemical product packaging materials. Ideal choice. The bubble medicine barrel has the advantages of seamless integral polyethylene (PE), impact resistance, aging resistance, light weight, no leakage, acid and alkali resistance, long service life, and compliance with sanitary standards. Its performance is far better than glass fiber reinforced plastic, Traditional containers such as plastic welding and steel-lined rubber. Bubble barrels can be lined with different materials provided by steel drum suppliers and can be stored and transported for several months in similar environmental conditions.

Application of Stacked Screw Sludge Dewatering Machine in Textile Wastewater Treatment

Application of stacked screw type sludge dewatering machine in textile wastewater treatment. The water demand of the textile industry is very large, in which the treatment of sewage discharge is also very large, textile wastewater water flow, high content of organic compounds, water complex. PH value of sewage, CODCr, BOD5, color, etc. are not the same. The treatment method covers a large total area, the project investment is large, the renovation cost is expensive, and the product cost continues to rise. And whether it is anaerobic fading method or biofilm method, the treatment method of residual sludge is indispensable, so the sludge stack screw sludge dehydrator can play a great role, better overcome the textile wastewater residue.

Advantages of applying stacked screw sludge dewatering machine to carry out dedrying

Stacked screw sludge dewatering machine has compact structure and low comprehensive price compared with other types of dewatering machine. The structure is compact, the adjustment maintenance position is less, the daily management is simple. Turn on the main power switch of the equipment and the equipment, and then check the status of the display and the display lamp to see if there is any problem. After drying, it cannot be discharged from the sewage outlet. Instead, it can be immediately sent to the mud truck according to the shaftless screw conveyor, thus creating a stacked screw sludge dehydrator and reusing it many times. When the stacked screw sludge dewatering machine is in normal operation, the melted sludge is discharged in the form of filter cake. Proposed large, medium and small industrial equipment application spiral

Automatic dosing device: improve the efficiency of sewage treatment

The automatic dosing device can improve the efficiency and quality of sewage treatment and reduce operating costs, which is a kind of sewage treatment equipment with wide application prospects.
