Screw Press Sludge Dewatering Machine

The motor frequency of the concentrated cross-section is mainly controlled by the filtration of sludge free water, with the motor frequency of the concentrated cross-section generally maintained between 15Hz and 20Hz. The motor frequency on the news section is primarily for adjusting the speed of the news section. The higher the frequency, the faster the filtration speed, and the thinner the sludge cake. The motor frequency of the press machine is adjusted based on the thickness of the sludge cake and the sludge around the filter belt. The frequency of the crushing section motor is typically between 25Hz and 35Hz. The frequency of the excess sludge pump is related to the high sludge concentration and the dewatering of the dewatering unit. When the sludge concentration is low, the frequency increases, and the sludge input also increases. When the sludge concentration is high, the frequency decreases, and the sludge input decreases. The frequency adjustment of the remaining pump also considers the concentration of the flocculant solution and the belt conveyor mechanical load. The dewatering machine is part of the dewatering system, while other equipment serves the dryer. Therefore, to ensure the normal operation of the dryer, it is necessary to ensure the normal operation of other equipment.

During the operation of the screw press, the following issues may arise: filter belt misalignment. The misalignment of the filter belt refers to the offset on the outside of the control rod, triggering the deviation alarm switch. Normally, the control rod for canceling the filter belt deviation and the cylinder adjust the correction direction of the filter belt deviation, not the super part; this might be due to the valve not receiving the filter belt deviation signal, the rectifying cylinder not functioning, pressure issues, checking the integrity of the rectifying elements, accessories for the screw press sludge press, the integrity of the rectifying circuit, and the气管 integrity. Rectification work on the roller. Poor filter performance. The poor performance of the filter belt may be due to insufficient backwash water pressure, nozzle blockage, poor sludge flocculation, and excessive presence of flocculants. Slurries running in the dewatering machine. The slurry running in the screw press may be due to a large amount of slurry and poor flocculation. Thin sludge cake in the dewatering machine.

Sludge cake is lower, possibly due to lower residual sludge concentration, reduced slurry input, poor flocculation effect, and faster in the crushing section. The screw press system has two control programs: automatic operation and manual operation. The manual operation procedure for the screw press is as follows: turn on the equipment to start the air compressor - prepare the flocculant solution - tension the belt of the filter press section - start the motor in partial mode - open the recycle pump - Yinan screw press sludge filter press - open the feed pump and the residual sludge pump - start the screw conveyor. For automatic operation, simply press "Automatic Run" - "Start Automatic Run". In automatic operation, the screw conveyor needs to be manually started. The operating parameters of the dryer can be adjusted based on two conditions. Always check if the pipeline valves are open before turning on the equipment.

Screw Press Sludge Dewatering Machine Operation Steps

Screw Press Sludge Dewatering Machine Operation Steps

First, fill the PE bubble material drum with water, turn on the stirrer, then add the material according to the ratio of the preliminary test, and stir for about 30 minutes before adding.

②Before operating the screw press, please check if the rotation direction of the dewatering body is consistent with the direction indicated by the manufacturer.

③ Is the gap on the mudboard set within a reasonable range? If there's a significant discrepancy, please adjust it.

After everything checks out, you can proceed to run it.

④First, start the sludge pump and simultaneously activate the flocculation mixer. We offer screw press sludge dewatering machines, main shaft motors, and pricing for screw press sludge dewatering machines. Observe the changes in floc formation and water viscosity in the flocculation mixer to adjust the dosages and sludge flow rates until maintaining the stable state (flocs clumping together, water clear and non-viscous).

⑤ Observe the sludge moisture content at the front end of the screw press, and if it's not ideal, adjust it by modifying the mud pressure plate and the main shaft motor's variable frequency inverter.

⑥Please note that the mud cake moisture content after the screw press is generally between 75-85%. Do not over-pursue the moisture content, as it may lead to negative consequences such as motor overload and increased equipment wear.

Before shutting down, turn off the main shaft motor, loosen the mud plate, then start the main shaft motor again to allow the dried mud inside to fully drain out until thin mud exits the outlet. First, turn off the sludge pump, feed pump, and flocculation mixing motor (if not to be used for a long time, open the flocculation tank drain valve before turning off the flocculation mixing motor to empty the tank of sludge and prevent condensation). Observe the outlet until no sludge is discharged, then turn off the main shaft motor. Subsequently, rinse the dewatering drum and the process is complete.

Screw Press, also known as the Screw Sludge Dewatering Machine, is a water treatment system widely used in urban sewage treatment projects, petrochemical, light industry, chemical fiber, papermaking, jade processing, leather, and other industrial sectors.

A screw press is a compact, space-saving, low-energy-consuming, low-maintenance, high-energy-saving, technologically advanced, easy-to-maintain, lightweight, and easy-to-handle equipment. It is particularly suitable for sludge in industries such as urban sewage, domestic sewage, food, beverage, chemical, and leather. Next, let's delve into the advantages of the screw press. Let's take a look!

Screw Press is suitable for sludge treatment in industries such as urban sewage, domestic wastewater, food, beverage, chemical, leather, welding materials, papermaking, dyeing and finishing, electroplating, oilfields, coal mines, winemaking, animal husbandry, kitchen wastewater, water treatment plants, power plants, and steel mills.
