Introduction to supporting equipment of stacked screw sludge dehydrator

 In practical application, the stacked screw sludge dewatering machine can start work immediately without building a sludge concentration tank, integrating extraction, concentration and dehydration of sludge. The use of stacked screw sludge dewatering machine requires the addition of medicine. The function of adding medicine is to cause the mud water to achieve a flocculation effect. The medicine is commonly known as polyacrylamide (PAM) anion and cation. It is non-toxic, crystalline, odorless, and non-toxic. It is easy to cause harm to the entire wastewater system. Generally, drugs with an ionicity of 40 and a content of 12 million are used for desliming. Special sludge requires the use of specific specifications from the drug manufacturer. The stacked screw sludge dewatering machine requires the addition of polyacrylamide anionic and cationic drugs, and the usage amount is very small, which solves the problem of cost concerns of customers.

 

PAM dosing device

Dosing device for supporting facilities and equipment of stacked screw sludge dehydrator. The dosing device is an essential equipment for industrial wastewater treatment. The sludge is flocculated by adding drugs and then enters the snail stacking spindle bearing for dehydration. The drug added to the snail stacker is usually PAM, the Chinese name is polyacrylamide, and the content is 150 10,000-20 million, the concentration value is usually 8%. The organic polymer coagulant has a huge surface adsorption effect by forming larger flocs between particles, and flocculates the suspended solids in the wastewater into alum flowers. The preparation of dosing is therefore a subjective factor in the dehydration effect, so it is necessary to select a suitable dosing device for stacking snails.

The PAM dosing equipment consists of a powder doser, three dissolving tanks, a stirring device, a metering pump, a liquid level gauge, etc. The complete set of machinery and equipment adopts 3-stage mixing, so that PAM can fully contact and dissolve with water. The dosing device is very simple to use. PAM is added into the powder doser, and the medicine is dispensed by controlling the spiral tube of the powder doser. After sufficient mixing at level 3, it is accurately added to the required water quality through the metering pump. .

 
Sludge pump 

The supporting facilities and equipment of the stacked screw sludge dehydrator are sludge pumps. Sludge dehydration treatment used to be a sludge pump for the conveyor. As the conveyor equipment with high viscosity, the sludge pump should have the following characteristics:

No coil blocking issues.

The shaft and oil chamber have reliable sealing and are protected against leakage.

Easy to install and takes up little space.

Easy to use, easy to maintain, small motor rated power, noise control.

The quality and rationality of the supporting facilities and equipment of the stacked screw sludge dehydrator are closely related to the quality of the dehydration effect of the equipment. Some manufacturers may use poor quality supporting facilities in order to control costs. Although the price of the equipment is very cost-effective, the processing effect and service life are much worse! Problems with a small component in the supporting facilities and equipment will affect the normal operation of the screw stacking machine. Therefore, when choosing equipment, you must choose these old factories with reliable quality. Our company is committed to the research and development of new technologies for environmental protection and governance, sewage sludge treatment technology, Application and equipment manufacturing, welcome to consult!
