    As an important part of the sludge dehydration equipment used in sludge treatment plants. This innovative machine plays a vital role in the sludge thickening process, helping to effectively remove moisture from the sludge to produce a drier, more manageable end product.


    The structural principle of the Screw Press sludge dehydrator is based on a series of key operating steps. Materials enter the machine through the feed port and are then transported by the screw conveyor within the equipment. This is the first step in the liquid separation and dehydration process.

    Once inside the dehydrator machine, the material is subjected to the action of a rapidly rotating propeller. The propeller creates centrifugal force, causing moisture and solid particles within the material to separate. Smaller solid particles are pushed toward the drain, while moisture is expelled through the filter. This separation process is critical to the overall efficiency of the dehydrator.


    Finally, the solid particles are discharged from the sludge concentrating equipment through the discharge port, leaving behind drier and more concentrated sludge. On the other hand, moisture drains away through the drain. To sum up, the spiral sludge dehydrator can effectively separate the moisture and solid particles in the material through the rotation of the propeller and the action of centrifugal force. This mechanism ultimately achieves the intended purpose of dehydration and sludge concentration.

    In summary, the structural principles of the screw press sludge dehydrator highlight its importance as a basic component of the sludge treatment plant. By effectively removing water from the sludge, this innovative sludge treatment machine helps improve the overall efficiency of the sludge treatment process, helping to produce a more manageable and environmentally friendly end product.


    1.The main body of the screw dewatering machine is composed of a fixed ring and a swimming ring superimposed on each other, and the filter device formed by the screw shaft runs through it. The front section is the concentration part, and the back section is the dehydration part.
    2. The filter seam formed between the fixed ring and the swimming ring and the pitch of the screw shaft gradually become smaller from the concentration part to the dehydration part.
    3. The rotation of the screw shaft promotes the transportation of sludge from the concentration part to the dehydration part, and also constantly drives the swimming ring to clean the filter seam to prevent blockage.
    4, sludge in the concentration part after gravity concentration, is transported to the dehydration part, in the process of progress with the filter and pitch gradually smaller, as well as the blocking effect of the back pressure plate, produce great internal pressure, volume continues to shrink, to achieve the purpose of full dehydration.

    Project Introduction

    Working principle of screw dewatering machine:

    The integrated screw type sludge dewatering system can be directly moved to the sludge tank for sludge dewatering treatment according to customer needs.

    The integrated dosing device in the sludge treatment system is responsible for the dissolution and ripening of the agent, and the screw sludge dewatering machine completes the dewatering treatment of the sludge, and then the mud cake is transported to the designated place by the shaftless screw conveyor. The system contains sludge pump, dosing pump, only external power supply and washing water source can independently complete the work of sludge dewatering machine room.

    The stacking screw type sludge dewatering machine is a new solid-liquid separation equipment that uses the principle of screw extrusion, through the strong extrusion pressure generated by the change of screw diameter and pitch, as well as the small gap between the swimming ring and the fixed ring, to achieve the extrusion and dehydration of sludge.


    1. The main body of the stacked sludge dewatering machine is a filter device formed by the superposition of fixed ring and swimming ring, and the spiral shaft through it.

    2. The small movable filter formed between the fixed ring and the swimming ring filters the filtrate. The inner cavity formed by the spiral shaft and the ring is full of floculating particles, which are transported to the end of the back pressure plate during the rotation and the formation of mud cake.

    3, the spiral shaft rotation push, constantly drive the movement of the swimming ring up and down the left and right to clean the filter seam, to prevent blockage.


    Screw type sludge dewatering machine is a kind of equipment that can effectively separate sludge from water. Its main functions include the following aspects. First of all, the screw type sludge dewatering machine can effectively treat sewage. Sewage is often mixed with various impurities, the most common of which is sludge. Through the screw type sludge dewatering machine, the sludge can be separated to achieve the purpose of purifying sewage. Secondly, the screw type sludge dewatering machine can dehydrate the sludge. This is because the sludge contains a lot of water, after dehydration can greatly reduce its volume, convenient for subsequent treatment. The screw type sludge dewatering machine can remove the water from the sludge, so that the sludge becomes drier. In addition, the screw type sludge dewatering machine has an important function, that is, it can transport the dehydrated sludge. For some sludge treatment plants, it is necessary to transport the collected sludge to a specific location for further treatment. The screw type sludge dewatering machine can not only dehydrate the sludge, but also transport the sludge to the corresponding place. In short, the main function of the screw type sludge dewatering machine is to treat sewage, dehydrate sludge, and transport dedehydrated sludge. This equipment has a wide range of applications in urban sewage treatment, chemical enterprises and other industries. By using the screw type sludge dewatering machine, it can not only purify the sewage, but also facilitate the subsequent treatment and improve the treatment efficiency.


    The Advantages of Screw Sludge Dewatering Machine

    As an innovative sludge dewatering equipment that has many advantages compared with traditional sludge treatment methods.

    One of the main advantages of spiral sludge dehydrators is their wide range of applications. They are used in a variety of industries, including municipal wastewater treatment plants, petrochemical, textile, paper and food processing industries. This versatility makes them a valuable asset to any sludge treatment plant.
    Another major advantage of spiral sludge dehydrators is their ability to prevent clogging. The moving and fixed filter gap structure of these machines reduces the likelihood of clogging, eliminating the need for extensive cleaning. This not only saves time but also ensures continuous and efficient operation.


    In addition to preventing clogging, the spiral sludge dehydrator also has the advantage of continuous automatic operation. The machines are equipped with automatic control systems that handle everything from pumping out the sludge to injecting chemicals and discharging the sludge cake. This level of automation reduces the need for humans to operate the equipment, resulting in significant savings in labor costs.

    In addition, the overall design of the spiral sludge dehydrator is compact and efficient, thus reducing operating costs. The low-speed screw extrusion technology used in these machines also helps reduce power consumption. In addition, the self-cleaning function of laminate minimizes water consumption and eliminates secondary contamination of water.

    The lightweight yet durable construction of the spiral sludge dehydrator is another significant advantage. Their mechanical squeeze dewatering method does not require large drums, making them more compact and easier to maintain. Additionally, its stainless steel construction and minimal replacement parts ensure long life and durability.


    By processing aerobic sludge directly in the aeration tank, the spiral sludge dehydrator can also reduce project investment costs. This eliminates the need for separate sludge thickening and storage units, saving overall space and construction costs for wastewater treatment facilities.

    Finally, screw sludge dewaterers provide environmental benefits through enhanced phosphorus removal capabilities. The dehydration process takes place under aerobic conditions to prevent the release of phosphorus from the sludge. This helps minimize the environmental impact of the sludge treatment process.

    In summary, the advantages of the spiral sludge dehydrator make it an important part of modern sludge treatment facilities. From their wide range of applications to their cost-saving and environmentally friendly features, these machines are a valuable investment for any organization looking to streamline their sludge treatment processes.
