Multi-disc screw mud press is one of the most popular types of mud presses in Vietnam as well as in many countries around the world. Similar to other types of sludge presses, multi-disc screw presses are also used in the final stage of wastewater treatment. In the framework of this article, we will provide detailed information about the structure and operating principle of the multi-disc screw press.
Structure of screw presses
Different from other types of slurry presses such as conveyors and plate frames with filter cloth accessories, plate frame mud presses, machine bodies, etc., structure of multi-disc screw presses are divided into 4 regions:
Zone 1 and zone 2 have large gap sizes between stainless steel rings with the main task of separating water.
Zone 3 has a smaller gap between the stainless steel rings, which is responsible for performing the preliminary pressing process and separating the water present in the sludge.
Zone 4 has a very small gap between the stainless steel rings. This area is combined with the sludge pressing disc to reduce the moisture content of the sludge below 80% and then it is taken out.
Basic working principle of multi-disc screw slurry press
The screw slurry press is designed to operate on the principle of a torsion load shaft operating continuously inside a circular mesh cage assembled in two halves.
When there is feed material (sludge is in liquid form), the screw conveyor will lift the material forward. The screw will take care of both transporting raw materials and pressing the materials together to squeeze the water until the sludge adheres to the residue and reaches a certain dryness.
After the sludge has been glued together and reached the required dryness, the screw will push the waste material in turn through the screw slot to fall out according to the trough installed at the outlet of the machine. The water after the separation process will be collected by a conical funnel installed right under the body of the machine.
What industries are screw slurry presses used in?
Besides the application in the field of sludge treatment, garbage, microbiological sludge, chemical sludge, fish pond sludge, it is also used in the following production and processing industries:
Squeezing shrimp shells, seafood, waste products of seafood processing factories such as shrimp shells,’
Pressing oil in the preparation of vegetable oils of all kinds: peanut oil, coconut oil.
Pressing fruits in food processing such as pineapple, melon, sugarcane, etc.
Advantages and disadvantages of multi-disc screw press in operation hoạt
Quiet, smooth, gentle operation without noise – Quiet, gentle operation;
The machine works continuously, not cyclically
The body is durable because it is made from good materials
The dryness of the mud cake is quite high, but it is still lower than that of the frame mud press
The machine has an uncomplicated design that is easy to operate for users
The selling price of screw mud presses is quite high, 2.5 times higher than similar machines
Low machine productivity High initial cost (2.5 times higher than similar machines);
Slurry press accessories for this type of machine are not available, so it is difficult for maintenance and replacement of equipment of the machine.
Compared with other types of mud presses of the same type, screw mud presses also have more outstanding advantages and also have certain disadvantages.
