The ENDLESS BELT FILTER achieves solid - liquid separation by applying negative - pressure suction technology. The liquid to be filtered flows into the filter tank paved with special filter cloth, which is part of the endless belt system. A vacuum pump beneath the tank creates a negative - pressure environment, which enables the liquid to quickly pass through the filter cloth on the endless belt, gather at the bottom of the tank, and then be pumped to the clean liquid tank by a filter pump. Solid impurities are left on the surface of the filter cloth, forming a filter cake.
To maintain the filtration performance, the equipment is equipped with a filter cloth cleaning system. When the filter cloth on the endless belt is overly soiled, the drive motor starts to move the endless belt. Simultaneously, the brush sweeps off the filter residues, and then the reverse - flush pump extracts clean liquid from the clean liquid tank and flushes the filter cloth on the endless belt from the inside out through a special pipeline under high pressure, preventing clogging and ensuring filtration efficiency.

The dirty liquid flows into the interior of the drum of the drum - type filter. The drum rotates slowly under the drive of the motor, with a paper - tape wound around its outer surface. Under the action of gravity, the liquid passes through the paper - tape and flows downward, while the impurities are intercepted on the paper - tape to form a filter cake. When the filter cake thickens or the filtrate flow rate decreases, it indicates that the filtration performance of the paper - tape declines. At this time, the liquid - level sensor monitors that the liquid level rises to the set height due to the blockage of the filter cake, and then triggers the transportation of the new paper - tape and the discharge of the used paper - tape to maintain the filtration work. The clean liquid flows into the water tank below for subsequent use.

The liquid containing impurities flows into the filter tank, where the filter paper is laid on the stainless - steel mesh chain. Under the action of gravity, the liquid passes through the filter paper, and the impurities are retained on the filter paper, forming a filter cake. The liquid - level sensor above the filter paper monitors the liquid level. When the filter cake thickens and causes the liquid level to rise to the preset height, the sensor sends a signal to the control system. The system then activates the filter - paper transmission device, which transports new filter paper to the filtering position and winds up the used filter - paper tape, ensuring continuous and efficient filtration.

Grinding oil pre - coating filtration is a technology that coats a filter aid on the surface of a filter tube to filter out impurities in the grinding oil. By taking advantage of the porous structure of the filter aid, when the oil flows through the pre - coated element, impurities are blocked, achieving the separation of the oil and impurities.
• Efficient Filtration: The tube - type elements have a large filtration area, and the filter - aid pre - coating layer intercepts tiny impurities, resulting in high filtration efficiency.
• High Precision: By selecting the filter aid according to requirements and adjusting the thickness of the pre - coating layer, a precision of 5 - 10μm can be achieved.
• Good Stability: The element material is firm and not easy to fall off, ensuring the stability of the filtration effect.
• Easy Maintenance: The back - flushing system regularly cleans, reducing manual maintenance, and the element replacement is convenient.

In industrial production, the efficient filtration of liquids has a significant impact on product quality and production efficiency.
It achieves solid - liquid separation based on negative pressure suction. After the liquid containing impurities flows into the dirty liquid chamber, the system rapidly generates negative pressure. Under the action of negative pressure, the liquid quickly penetrates the filter paper. The filter paper precisely intercepts fine impurities, and the impurities accumulate to form a filter cake, while the clean liquid flows into the clean liquid chamber or the liquid storage tank. The intelligent control system of the device can monitor the thickness of the filter cake and the vacuum degree in real - time. When the filter cake thickens to make the vacuum degree in the negative pressure chamber reach the preset value, or the liquid level in the dirty liquid chamber rises to a high level, the filter paper replacement program is automatically activated to ensure stable filtration efficiency.

• Easy Management: Centralized treatment facilitates the unified management and maintenance of cutting fluids by enterprises, improving management efficiency.

The electrostatic oil mist machine operates based on the principle of electrostatic adsorption. The air containing oil mist and smoke enters through the air inlet and first passes through a pre - filter to remove large - sized particles. Then, the gas enters the ionization zone. Under the action of a high - voltage electric field, the oil mist particles are ionized and charged. Driven by the electric field force, the charged oil mist particles move towards the collection plates with the opposite polarity, adsorb on them, and then gather into droplets that flow down along the collection plates and into the oil collection tank at the bottom, thus completing the air purification process.
