The disc filter is an indispensable device for the medium pipeline of the conveyor belt. It is usually installed on the inlet equipment of pressure reducing valves, drain valves, constant water level valves and square filters. The filter is composed of a stainless steel filter, a sewer section, a transmission device and an electrical control section. The water to be treated passes through the filter of the filter. Impurities are clogged. When cleaning is required, the detachable filter bucket can be disassembled and reassembled after processing. It is very convenient to use and maintain.

What is the principle of the backwashing stage of the disc filter?

When a specific pressure difference is reached or within a set time, The system will automatically enter the backwashing state. The control valve changes the flow direction. The unidirectional diaphragm at the bottom of the filter closes the main channel. Reverse refresh to four groups of nozzle channels. The water pressure in the piston chamber connected to the nozzle channel rises, the piston moves upward to overcome the pressure on the spring, and the piston space is released from the top of the stacked group. Meanwhile, water is washed in reverse along the stacked tangent from the nozzles above the four sets of nozzle channels. After reverse cleaning, the direction of water flow changes again, and the overlapping part is pressed in once more. The system enters the filtering state again.

Accumulation

Precise filtration

According to the water usage requirements, Different precision filter discs can be selected.." The specifications include 20 microns, 55 microns, 100 microns, 130 microns, 200 microns, 400 microns, etc. The filtration rate is greater than 85%.

Effective backwashing.

During backwashing and centrifugal spraying, the filter holes are fully open. It has achieved a cleaning effect that other filters cannot reach. The backwashing process for each filter unit can be completed in just 10 to 20 seconds.

Fully automatic operation, continuous drainage.

Backwash startup is controlled by time and pressure difference. In the filtration system... Each filter unit and workstation is backwashed in sequence. The working and backwashing states are automatically switched, which not only ensures continuous drainage but also reduces system pressure loss, avoiding the deterioration of filtration and backwashing effects due to usage time.

Modular design

Users can select the number of parallel filter units as needed, which are flexibly interchangeable. Make flexible use of the corner space on site and install it in a small area according to local conditions.

Simple to maintain.

There is almost no daily maintenance, no dedicated inspection tools, and very few detachable parts.

Laminated filter Installation precautions.

1. The equipment should be installed on a bypass. So that the equipment can be inspected and maintained continuously.

2. The equipment can be installed horizontally or vertically according to the on-site conditions. The equipment needs to be connected to the pipeline according to the direction of water inlet and outlet.." When installed vertically, the water inlet of the equipment should face upwards. When installed horizontally, the sewage outlet should face downward.

3. Valves should be installed at the water inlet, water outlet and sewage outlet of the equipment (the sewage valve should be a quick valve).
