Rotary mechanical screen is a specialized equipment used for water treatment, and its detailed introduction is as follows:

working principle

Driven by a motor reducer and equipped with unique rake teeth, the floating scum on the water surface is salvaged. When the rake chain is moved to the upper part of the equipment, due to the guidance of the groove wheel and curved rail, each set of rake teeth produces relative self-cleaning motion. The vast majority of solid materials fall down by gravity, while the other part is cleaned by the reverse movement of the cleaner to remove debris stuck to the rake teeth.

Characteristics of rotary mechanical screen machine equipment

Equipment features

High degree of automation: The equipment operation interval can be adjusted according to user needs to achieve periodic operation; It can automatically control the start and stop of the equipment based on the liquid level difference before and after the screen, and also has manual control function, which is convenient for maintenance.

High separation efficiency: It can continuously and automatically intercept and remove various shapes of debris in the fluid, effectively intercepting solid particles, floating objects, etc. in sewage, ensuring the smooth progress of subsequent treatment processes.

Low power consumption: The equipment operates with low energy consumption, saving energy costs.

No noise: The noise generated during operation is minimal and will not cause noise pollution to the surrounding environment.

Good corrosion resistance: The equipment is made of corrosion-resistant materials or treated with anti-corrosion measures, and can operate stably for a long time in harsh sewage environments.

Strong self-cleaning ability: The structural design is reasonable, and it is not easy to cause blockage during operation, reducing daily maintenance workload.

Construction composition

It mainly consists of a frame, power unit, rake chain, cleaning mechanism, and electrical control box.

application area

Widely used in urban sewage treatment, water supply industry, power plant inlet, and can also be used as a front-end screening equipment in wastewater treatment processes for industries such as textile, food processing, papermaking, leather, etc.

Equipment specifications

The equipment specifications are divided according to the machine width size, commonly including GSLY300-3600 type, etc. When the machine width exceeds 1800mm, it is made into parallel units. There are various specifications for the rake teeth gap, including 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, 30mm, 40mm, 50mm, etc. The selection should be based on the amount of water, lifting height, total solid-liquid separation, and the shape and particle size of the separated material. Different materials can also be selected according to the needs.

Installation and maintenance

Installation: Usually, the whole machine is lifted, and no other supports are needed on both sides of the water collection well. Steel plates are pre embedded on the ground, and the supporting steel plates on both sides of the frame are welded together during installation.

Maintenance: Daily inspection of equipment appearance, operating status, and debris cleaning; Regularly inspect transmission components screen、 Overhaul the rake teeth, motor, and electrical system; When blockages, transmission component failures, motor and electrical system failures occur, they should be promptly investigated and dealt with. During maintenance, attention should be paid to stopping the machine, cutting off power, wearing protective equipment, following operating procedures, and preventing sewage splashing and other safety precautions.
