Laminated filters are indispensable equipment for conveyor belt media pipelines, usually installed on the inlet end equipment of pressure reducing valves, discharge valves, fixed water level valves, square filters and other equipment. The filter consists of a stainless steel filter, a sewer section, a transmission and an electrical control section. After the water to be treated passes through the filter of the filter filter, the impurities are blocked, and when it needs to be cleaned, the removable filter bucket can be removed and reloaded after treatment, so it is very convenient to use and maintain.

　　What is the principle of the backwash stage of a laminated filter?

　　Upon reaching a certain pressure difference or within a set amount of time, the system will automatically enter a backwash state. The controller controls the valve to change the flow direction. The unidirectional diaphragm at the bottom of the filter closes the main channel and reverses to 4 sets of nozzle channels. The water pressure in the piston cavity connected to the nozzle channel rises, the piston moves upward to overcome the pressure on the spring, releasing the piston space from the top of the stack group, and at the same time reverse cleaning the water from the nozzle above the 4 sets of nozzle channels along the stack tangent.

　　What are the characteristics of lamination filters?

　　filtration

　　According to the requirements of the water, you can choose 20 microns, 55 microns, 100 microns, 130 microns, 200 microns, 400 microns and other specifications, with a filtration rate of more than 85%.

　　Backwashing

　　When backwashing, the filter hole is fully opened, and the centrifugal injection action can achieve a cleaning effect that other filters cannot achieve. The cleaning process of each filtration unit can be completed in 10 to 20 seconds.

　　Fully automatic operation, continuous water discharge

　　Time and differential pressure control backwash. Within the filtration system, reverse washing is carried out sequentially between individual filtration equipment and workstations. Automatic switching between working and backwash states ensures continuous water output, reduced system pressure loss, and no deterioration in filtration and backwashing over time.

　　Modular design

　　Users can choose the number of parallels, flexibility, and interchangeability of the filter units according to their needs. It can flexibly use the corner space on site and takes up less space according to local conditions.

　　Maintenance is simple

　　Requires little routine maintenance, inspections, specialized tools, and few removable parts.

　　What are the installation considerations for lamination filters?

　　1. The equipment should be set up with a bypass for repair and maintenance without downtime.

　　2. The equipment can be installed horizontally or vertically according to the site conditions, and the equipment should be connected to the pipeline according to the direction of the entrance and exit, and the water inlet of the equipment is facing up when installed vertically, and the discharge port is facing down when installed horizontally.

　　3. Valves should be set up at the water inlet, drain port and discharge port of the equipment (the discharge valve should be a quick valve).
