The Hengman Spiral Press Dewatering Machine, paired with a specially designed spiral body, boasts exquisite design and a variety of product models. It ranges from ultra-small dewatering machines with a processing capacity of 0.5kg-DS/h to ultra-large dewatering machines of 1320~1360kg-DS/h. The dimensions span from 1920mm*75mm*989mm for ultra-small dewatering machines to 5300mm*3180mm*2400mm for ultra-large dewatering machines. It can provide suitable technical solutions based on the actual processing capacity requirements of customers.
The mixed liquid flows into the filter cylinder of the screw press dewatering machine through the feed port, which is assembled by alternating fixed and movable plates. Driven by the screw shaft, the material moves towards the end of the discharge port. As the pitch between the screw shaft and the blades gradually decreases, the pressure on the sludge increases, and it begins to dewater under the action of the pressure difference. The free water flows out of the filtering gap between the movable and fixed plates.
Due to the larger diameter of the screw shaft compared to the aperture of the moving plate, the shaft rotates,带动the plate along with it. The dewatering machine achieves self-cleaning through the relative motion between the moving and fixed plates, preventing clogging of the filter gaps. After complete dehydration, the sludge cake is discharged from the discharge port under the push of the screw shaft. Since there is always relative motion between the fixed and moving plates, some small mud particles are always squeezed out with the water through the gaps.
To prevent sludge particles from settling on the filter element surface, an automatic water spray washing system is installed. The filter element surface is regularly rinsed with spray washing to maintain cleanliness. The mud cake has a moisture content of 78%-85%, a solid recovery rate of over 95%, and the screw shaft rotates at 2-3r/min with no vibration or noise. It can be directly dewatered at low temperatures.
The overflow water from the screw press dewatering machine has a certain turbidity. Since the filtered water returns to the biological treatment system, a certain degree of turbidity in the filtrate is permissible. The gap between the fixed and movable plates is fixed at the factory and cannot be adjusted arbitrarily. The water content of the filter cake can be adjusted by regulating the gap of the back pressure plate and the feed rate.
The Hengman Spiral Dewatering Machine features a small footprint, self-cleaning without clogging, low noise and energy consumption, fully automatic with no need for on-site staff, cost-saving for infrastructure, wide application range, and is particularly adept at handling low-concentration sludge. Welcome to consult with our customers!
The application of screw press sludge dewatering machines is becoming increasingly widespread, and the demand in the market is growing as well. During the initial procurement phase, selecting the appropriate model becomes the top priority. Currently in China, there is no unified standard for screw press sludge dewatering machines, and each manufacturer's equipment has its unique features. However, some manufacturers have corporate standards, while those without them offer less guaranteed quality compared to those with corporate standards.
In this case, when selecting a screw press sludge dewatering machine, the first priority is to address the issue of sludge output. Consider the cost of treating waste liquid on-site daily, as well as the cost of water content in the solid-liquid mixture or sludge concentration. Next, based on comprehensive data such as the daily or hourly sludge output of the manufacturer's equipment and the water content of the dewatered sludge cake, you can choose the appropriate model. If it's still too complex, many manufacturers now offer selection services. You can directly consult with the business representative to assist with the selection.
Due to a large population and rapid economic development, the city faces a significant amount of wastewater. In rural and town areas, with larger land areas and fewer people, the wastewater treatment capacity is limited. Therefore, the emergence of household wastewater treatment equipment is particularly welcomed. This equipment not only improves the wastewater treatment effect but also reduces the labor burden. Let's take a look at its detailed process.
。
5. Sludge Pond: All sludge from the primary and secondary sedimentation tanks is aerated into the sludge pond of the WSZ-A for aerobic digestion. The clarified liquid from the sludge pond is recycled to the heat exchange oxidation pond for further treatment. The remaining sludge after digestion is minimal, typically requiring cleaning once every 1-2 years. The cleaning method involves using a vacuum truck to extend into the bottom of the sludge pond through the inspection hole, and then suctioning and transporting it out.
6. Fan Room, Fans: The fans for the sewage treatment equipment are located above the disinfection area, with double-layer sound insulation at the intake. The intake features a muffler and fan filter. The Chengwu Spiral Sludge Press Filter ensures quiet operation. The fans are equipped with two rotating fans that can run alternately automatically. Each fan has a lifespan of approximately 30,000 hours.
7. Adjustment: Chemical wastewater has the characteristics of varying water quality and volume, which can change significantly within a day or a shift, especially when operations are abnormal or there are leaks in equipment or pipes causing material to enter the wastewater. Such changes in water quality and volume are detrimental to the proper functioning of drainage facilities and wastewater treatment equipment, particularly biological treatment equipment, as they can hinder or even damage the purification process. In such cases, a common measure is to install a regulating pond before the wastewater treatment system to adjust the water volume (equalization pond) and to homogenize the water quality (quality homogenization pond), ensuring the normal operation of wastewater treatment. Additionally, the equalization pond can also serve as a temporary storage for accidental drainage.
8. Centrifugal Separation: The treatment of wastewater through centrifugal separation utilizes the centrifugal force generated by rapid rotation to separate suspended particles in the wastewater. As the wastewater containing suspended particles undergoes rapid rotational motion, heavier solid particles are ejected to the outer periphery, while lighter ones remain in the inner circle, thereby achieving separation of the wastewater from the suspended particles, leading to purification of the wastewater.
From the process flow of the aforementioned domestic wastewater treatment equipment, we can also learn about its approximate configuration composition, as well as the functions and data requirements of each component, which is very helpful for the correct use of the equipment. In addition, we also hope that through understanding and learning various wastewater knowledge, we can better recognize the importance of environmental protection.
