　　Complete set of equipment for sludge treatment in sewage plants, including sludge centrifugal concentration and dewatering machine, horizontal centrifugal dewatering machine

　　Overview: The complete set of equipment for sludge treatment consists of a centrifugal concentration and dewatering machine, a PLC electronic control system, a fully automatic dosing device, a pump, a screw conveyor, a sludge cutting machine, etc.

　　Workflow of complete equipment for sludge treatment in sewage treatment plants:

　　The sludge to be processed is connected to the input end of the sludge feeding system through a pipeline, and is cut into impurities and long fibers by a sludge cutting machine. It is then fed by a sludge feeding pump with variable frequency flow rate. After being measured by a flow meter, it is input into the sludge dewatering host to achieve the feeding amount.

　　After the flocculant (powder) is prepared in proportion and fully dissolved and stirred in the dispensing tank, it enters the storage tank. The dosing pump determines the flow rate according to the dehydration process requirements and enters the dehydration host to mix with the sludge to be treated, flocculation into alum flowers. After the sludge is dehydrated by the dehydration host, the clarified sewage is discharged through the clarified liquid pipeline. The differential speed is automatically feedback adjusted according to the load and sludge concentration changes, and the pushing power is automatically compensated to ensure the constant dryness of the dehydrated sludge and obtain drier sludge cake. The mud cake is continuously discharged from the main machine's slag discharge outlet, and the sludge to be treated is continuously input. The continuous discharge and transportation of clarified liquid and dehydrated sludge is a fully automatic processing process. The dosing, feeding, sludge transportation, and operation status of the entire device are detected and controlled by the PLC electrical control box, making the device a fully automatic and intelligent complete operation unit.

　　The dehydrated sludge is pumped into the sludge bin by a screw pump. The stored sludge is regularly loaded onto trucks and transported out according to the height of the material bin.

　　The complete set of equipment for sludge treatment in sewage plants, including sludge centrifugal concentration and dewatering integrated machine and horizontal centrifugal dewatering machine, has the following overall advantages:

　　1、 Small footprint and simple process pipeline

　　The footprint of the sludge centrifugal concentration and dewatering integrated machine is only 1/5 of that of filtration equipment with the same processing capacity. The process pipeline is simple and does not require high-pressure air pipelines or high-pressure flushing water pipelines;

　　2、 High degree of automation

　　The series of processes including startup, feeding, separation, unloading, and shutdown cleaning are all implemented through the electrical control system, and users can start them with one click through the touch screen.

　　3、 High safety protection measures

　　The rotating components of the sludge centrifugal concentration and dewatering integrated machine are equipped with safety protection covers that meet national safety standards. The electrical control system is equipped with vibration and temperature detectors, and has alarm and interlock protection functions.

　　4、 Good on-site operating environment

　　The entire feeding, separation, slag discharge, and liquid discharge of the sludge centrifugal concentration and dewatering integrated machine are completed under fully enclosed conditions, without the need for flushing water during operation, ensuring the environmental hygiene of the production site. It is particularly suitable for industries such as flammable and explosive media, corrosive and odorous substances, and food and medicine.

　　5、 Strong adaptability of materials

　　The electrical control system of the sludge centrifugal concentration and dewatering integrated machine adopts constant torque control technology to monitor the pushing torque of the screw conveyor in real time, compare it with the set torque, and adjust the slag discharge speed (i.e. differential speed) of the screw conveyor in a timely manner to adapt to the changes in material characteristics caused by process changes.
