Hospital sewage spiral dewatering equipment

Hospital sewage spiral dewatering equipment

1 Product Overview

In modern hospital operations, sewage treatment is a key link related to environmental compliance, hospital infection control, and social responsibility. Among them, sludge dewatering is the final step in the sewage treatment process, and its effectiveness directly affects the cost of sludge disposal and environmental standards.

The Zhizhen series hospital stacked screw sludge dewatering machine is an efficient, continuous, and automated solid-liquid separation equipment that we have deeply developed based on the special characteristics of the medical industry. It has become an ideal choice to replace traditional belt and plate frame filter presses with its performance, extremely low operating costs, and excellent hygiene and safety design. It is a wise choice for modern hospitals, disease control centers, laboratories, and medical park sewage stations.

Core positioning: Provide a hospital with oneIntelligent sludge dewatering equipment that is "worry free, labor-saving, land saving, and cost-effective".

II Hospital sewage spiral dewatering equipmentCore advantages of the product

1. Efficient and energy-saving, with extremely low operating costs

Low energy consumption: The main spiral shaft operates at low speed, with energy consumption only comparable to traditional equipment1/10.

Water conservation and environmental protection: Adopting static spray self-cleaning technology, the flushing water consumption is minimal, and treated reclaimed water can be used to achieve water recycling.

Drug savings: Optimized flocculation mixing system enables more complete reaction between sludge and flocculant, effectively reducing the dosage of chemicals.

2. Fully automatic continuous operation, unmanned operation

One click start stop: integrationThe PLC automatic control system can achieve the automation of the entire process from mud inlet, dosing, mixing, dewatering, and sludge discharge.

Intelligent linkage: Seamless linkage with upstream lifting pumps, dosing devices, etc., achieving true meaningUnmanned operation greatly liberates manpower.

Remote monitoring (optional): Support IoT modules, which can be accessed throughReal time monitoring of operating status and receiving fault alarms on PC or mobile app.

3. Compact design with small footprint

Modular integrated design, Compact structure, occupying less space than traditional equipmentMore than 40%, especially suitable for sewage treatment stations with limited underground space in hospitals.

Easy installation: The equipment is shipped as a whole, and only needs to be connected to water, electricity, and pipelines on site to be put into operation, greatly reducing the installation cycle.

4. Safety and hygiene, adapted to the characteristics of hospital sludge

Core anti-corrosion: Core components such as spiral shaft, dynamic ring, and static ring are adopted304/316 stainless steel or special wear-resistant materials effectively resist the corrosion of disinfectants and chemicals that may be present in hospital wastewater.

Sealed design: The dehydration body is fully sealed, effectively preventing sludge splashing and odor leakage, avoiding the spread of pathogens, and meeting the requirements of hospital infection control.

Strong self-cleaning: The small gap between the dynamic and static rings generates mutual displacement during operation, which has self-cleaning function and prevents blockage from the root.

5. Dehydration is stable, and the solid content of the sludge is high

adoptThe principle of "progressive" spiral extrusion applies stable and increasing pressure to the sludge to ensure uniform and stable consistency of the sludge.

After treatment, the moisture content of sludge can be reduced to80% -85% (adjusted according to the nature of the sludge), forming a solid and low viscosity mud cake, which is convenient for subsequent packaging, transportation, and disposal.

4 Working principle (brief description)

After the sludge and flocculant fully react in the mixing tank to form flocs, they enter the main body of the snail dewatering system. In the filtering chamber formed by the stacking of fixed rings and moving rings, the spiral shaft drives the blades to slowly rotate, pushing the sludge forward. During the pushing process, the gaps between the filter chambers gradually narrow, applying increasing squeezing pressure on the sludge from small to large, causing the water in the sludge to be gradually squeezed and discharged, ultimately forming a dried sludge cake that is discharged from the discharge outlet, while the filtrate flows back to the sewage treatment system from the ring gap.
