3.1.1 Manual centrifugal filter
The manual centrifugal filter only relies on the pressure of the oil pump to provide the rotational driving force, and the centrifugal force generated is more than 1,800 times the gravity, which can directly drive the solid pollutants such as aluminum powder, impurities, particles and the like from the drawing emulsion.
The whole machine adopts adjustable working pressure, which is composed of centrifuge, oil pump, electrical, instrument and other parts.
The solid frame structure forms an integrated machine, and the universal four-wheel brake can ensure the safe operation of the equipment within the range of 0.5m2.
The working noise of this equipment can be as low as 80dB and the filtering accuracy can reach 10μm. According to the aluminum powder content concentration of the customer's drawing emulsion pool, the amount of aluminum powder separated per hour ranges from 0.5kg to 8kg, the degree of drying varies from 90% to 98%, and the emulsion content is less than 0.5%.
The whole machine has the function of overpressure, overload shutdown protection. When the operating pressure of the equipment is too high, it will automatically depressurize and shutdown. The operation only needs to click the switch, which makes it more convenient to use.
3.1.2 Main features:
Double spray structure, floating rotor body, self-lubricating structure, no abrasion and wearing parts；
Large dirty hold ability, small footprint, space saving, flexible movement and convenient maintenance；
Only the pressure generated by the oil pump is required to provide driving force, low energy consumption, maintenance-free, no need to replace any parts, rapid processing, etc.
3.2.1 Full-automatic centrifugal filter
The full-automatic centrifuge is a top-end equipment for aluminum powder processing of aluminum wire drawing machine. It has stronger centrifugal force to separate aluminum powder from the drawing emulsion.
The emulsion to be processed is sprayed into the rotary tank of the centrifugal filter from the bottom of the rotary body through an auxiliary pump. Under the high-speed rotation of the emulsion in the cylinder, the aluminum powder is separated from the emulsion and adsorbed on the rotor barrel wall. The separated emulsion overflows from the top of the rotating body, flows back to the drawing emulsion through the direction of the preset separation tank pool.
After the rotor cylinder has condensed certain aluminum powder and impurities, the equipment automatically reduces the rotor speed, automatically shuts off the emulsion and waits until the rotating body is completely stopped. The automatic slag removal function is activated to open the slag discharge opening, and the built-in scraper of the drive motor is activated to clean the aluminum powder. The scraper will rotate in order, rotating the coulter repeatedly and scraping out the aluminum powder cake. Under the action of gravity, aluminum powder falls from the slag discharge port into a collecting barrel below the equipment.
This machine adopts intermittent working mode. When the aluminum powder is separated, the emulsion pump works and the cleaning stops. During the cleaning operation, the aluminum powder and the emulsion pump stop working.
3.2.2 Main features:
The whole series adopts Siemens and Schneider CPU, frequency converter, touch screen, motor and other main components, and the whole machine runs stably, reliably and efficiently;
Solid one-piece frame welding and assembly process, more solid durability, ensure the whole machine working life longer;
The design is novel, the added structure is reasonable, the system runs stably and reliably, high intelligence, the automatic slag removing and oil discharging is realized, the manpower and material resources are greatly saved;
The automatic operation only needs to click the start and stop buttons to complete the operation. The system is equipped with manual / automatic switch, which can be set at any time in 24 hours, and 100% humanized operation;
No consumables, no maintenance, meet strict environmental requirements.
