Negative pressure paper tape filter machine

Negative pressure paper tape filter machineIt is a precision filtration equipment based on the combination of gravity settling and filter media adsorption, widely used in industries such as metal processing, automobile manufacturing, engineering machinery, refrigeration equipment, etc. for the purification treatment of cooling and cleaning fluids. The core working principle is to transport the contaminated liquid containing impurities to the filtration area through a circulating pump, and use specialized filter paper strips such as non-woven fabric or filter paper to intercept impurities. The purified liquid flows back to the storage tank for recycling, achieving efficient separation of pollutants and working fluid, with dual value of environmental protection and energy saving and improving processing quality.

Negative pressure paper tape filter machineCharacteristics:

1. The filtering accuracy is controllable and the range is wide. Different mesh sizes of filter paper strips can be selected according to processing requirements to achieve precise filtering of 5-100 microns. This not only meets the coarse filtering needs of ordinary turning processing, but also adapts to processes with high sensitivity to impurities such as precision grinding, effectively reducing surface scratches on workpieces and improving processing accuracy. For example, in bearing grinding, using a 5-micron precision filter can increase the surface roughness of the workpiece by 2 levels.

2. High degree of automation and easy operation and maintenance. Equipped with fully automatic paper feeding, paper breakage alarm, liquid level self-control and other systems, when the impurities intercepted by the paper tape reach the set thickness, the equipment can automatically switch to a new paper tape without the need for manual real-time monitoring; At the same time, there is a convenient paper tape storage box that only needs to be cleaned 1-2 times a week, greatly reducing the cost of operation and maintenance personnel.

3. The working fluid has a high recycling rate. Adopting a dual filtration structure of deep interception and gravity settling, the filtration efficiency can reach over 95%, extending the replacement cycle of the working fluid from 1-2 months in traditional equipment to 6-8 months, reducing waste liquid emissions by more than 80%. This not only reduces the cost of new liquid procurement, but also meets environmental protection and emission reduction requirements. After using it, a certain automotive parts factory saved over 150000 yuan in coolant costs annually.

4. Stable operation and strong adaptability. Adopting a stainless steel body and anti-corrosion pump body design, it can withstand corrosion from various working fluids such as emulsion and cutting oil, with a service life of 8-10 years; The equipment can be flexibly designed as horizontal, vertical and other structures according to the workshop layout, with a single processing flow rate covering 50-500L/min, suitable for single machine tools or multiple production lines for centralized filtration.

5. It has both impurity drying and environmental protection functions. Some models are equipped with hot air drying devices, which can reduce the moisture content of the intercepted waste residue to below 15% and decrease the volume of hazardous waste treatment; The fully enclosed filter chamber design effectively suppresses oil mist evaporation, improves the working environment of the workshop, and meets occupational health and safety standards.
