The cutting fluid is conveyed by the pipeline through the liquid supply pipe in the workshop to the machine tool or the automatic line, and the chips are flushed to the liquid returning system. Under the action of the pressure nozzle, the chips and the emulsion are returned to the filtering system through the overhead pipe or the underground pipe system. The emulsion in the filtration system is first coarsely filtered through the scraper sedimentation tank, and the larger chips are sent to the chip collecting box by the scraper conveyor, and then the emulsion is finely filtered by the negative pressure filter, and the net is filtered twice. The liquid is returned to the workshop by the pump set. The liquid supply pump set of the system adopts variable frequency constant pressure liquid supply technology to ensure the stability of the supply pressure and flow of the whole filtration system. When the quantity of equipment used in the workshop changes, the pressure in the pipeline also changes, and the pressure sensor will emit Signal, the pump set will automatically adjust the flow to make the pressure in the shop piping system constant. The dosing system consists of a dosing tank and a dosing pump and corresponding pipes and regulating valves, which can be automatically dispensed according to the set values. The aeration device periodically increases the oxygen in the liquid tank to inhibit the growth of the anaerobic bacteria and effectively extend the service life of the cutting fluid. The degreasing device automatically removes the surface oil slick to prevent the oil from corroding the cutting fluid. The system is equipped with a liquid level detection system that automatically detects the liquid level and outputs a signal. Automatic hydration function is provided to automatically replenish the system. The electrical control has manual/automatic/semi-automatic/holiday cycle four-mode to meet the needs of different working conditions. During the factory break and holidays, in order to prevent the cutting fluid from standing still for a long time, the system adds a recirculation pump. After the system stops running, the holiday cycle mode is selected on the control panel. The system automatically starts the recirculation pump to keep the cutting fluid flowing. Effectively inhibit the growth of bacteria, greatly extend the service life of cutting fluid, and achieve cost savings.
The concentrated liquid filtration system concentrates the liquid in the production workshop for centralized liquid supply and centralized treatment. It can concentrate the filtration, degreasing, aeration and sterilization of the coolant, and realize the control of its concentration, pH value and colony number. Ensure that the coolant does not deteriorate and prolong the service life of the coolant. The concentrated filtration and recirculation of the coolant can reduce the production cost, reduce the labor intensity of the workers, improve the working environment of the workshop, reduce the environmental pollution, and realize the centralized treatment of the waste coolant, thereby further reducing the pollution to the environment. What is important is that the coolant concentrated filtration system stabilizes the coolant quality for a long time and ensures the grinding ring needs of the bearing ring.
The concentrated supply and filtration system of grinding fluid has great promotion value. The one-time investment is not large, but the resource saving effect is obvious, the social effect is good, and the requirements for plant transformation are not high.
