Shanghai Jiucheng the internal scraper filter is a fully automatic self-cleaning filter. Due to its excellent performance, it is currently very popular in the market.

Shanghai Jiucheng internal scraper type filter structure composition: scraper type self-cleaning filter is composed of cylinder, filter screen, scraper system, pressure detection and industrial control system and automatic sewage system.

Shanghai Jiucheng the principle of internal scraper filter: the filter material enters the filter screen through the inlet flange, and the impurities larger than the gap of the filter screen are trapped on the filter surface side of the screen. After the filter screen assembly runs for a certain period of time, it is the difference between the inlet pressure and the outlet pressure. When the value reaches the preset value (the set value can be an empirical value or a debugging value), the PLC controller automatically starts the reducer to work and drives the rotating scraper to remove the dirt on the filter, and the control system can automatically calculate the degree of interception according to different materials and impurities Automatically control the working time and direction of the hob, then automatically open the drain valve to drain, and automatically control the drain time. Such reciprocating work can achieve the maximum reasonable self-cleaning filtering effect to remove impurities and minimize the wear of the filter.

Shanghai Jiucheng design features of internal scraper filter:

1) New scraper design, high-strength plastic scraper, spring compensation added to the original scraper, wear-resistant and corrosion-resistant;

2) The scraper system fits perfectly with the wedge-shaped net, and the impurities are completely removed;

3) The PLC control cabinet can display inlet and outlet pressure and differential pressure curves, as well as the working status of the equipment under various operating conditions;

4) The PLC control cabinet adopts three startup modes: differential pressure, time, and manual;

5) The USB interface can be connected with a keyboard and mouse to adjust the system parameters;

6) The scraper system is highly integrated and easy to install and replace.

Shanghai Jiucheng the scope of application of the inner scraper filter: it can be applied to the filtration of medium and high viscosity liquids, and has applications in many industries.

1) Industrial circulating water, circulating water, condensate water, and cooling water for blast furnaces, rolling mills, and continuous casting machines in the iron and steel industry;

2) Raw water filtration: seawater desalination, river water, surface water, and water pretreatment;

3) Environmental protection engineering: bag type, core type, UF, RO membrane and other pre-filtration;

4) Paper industry: raw water and white water filtration, protection nozzles;

5) Others: Cooling water and condensate water of central air-conditioning system, cleaning and filtering of petrochemical industry, automobile manufacturing, etc.
