Drum Filter Is A Type Of Filtration Machine That Occupies Less Space And Has Lower Operating Costs. Belonging To The External Filter Drum Vacuum Filter Machine, It Has The Characteristics Of External Filter Drum And Scraper Discharge, And Continuous Operation Under Vacuum.
In Grinding, With The Improvement Of Machining Accuracy, High-speed Grinding And Strong Grinding Technologies Have Developed Rapidly. In Addition To Selecting Reasonable Grinding Parameters, It Is Also Necessary To Improve The Circulation Quality Of Grinding Fluid.
Purification Devices Are Divided Into Two Types: Filtration Type And Power Type. Filter Type Filters Rely On Filter Media To Remove Impurities, Such As Filter Screen Type, Line Gap Type, Sheet Type, And Paper Tape Type Filters. Power Type Separators Rely On Certain Forces (such As Centrifugal Force, Magnetic Force, Or Gravity) To Separate Impurities, Such As Centrifugal, Vortex, And Magnetic Separators.
Processing Non Ferromagnetic Materials, Such As Stainless Steel, With Only Non Ferromagnetic Impurities In The Waste Liquid, Generally Uses A Paper Tape Filter. The Common Types Of Paper Tape Filters Are Gravity Paper Tape Filters, Drum Paper Tape Filters, And Negative Pressure Paper Tape Filters.
Drum Filter Machine Is A Universal Matching Filtering Equipment, Mainly Used For Filtering Coolant In Metal Grinding Or Other Processing, And Also Suitable For Removing Impurities From Cleaning Solutions, Industrial Water, Organic Solutions And Other Solutions In The Cleaning System Of Rough Parts. It Is A Key Equipment For Saving Resources And Preventing Public Hazards.
The Series Drum Filter Relies On The Gravity Of The Liquid Itself To Pass Through The Filter Cloth, Isolate Impurities, And Achieve The Purpose Of Purifying The Liquid. Its Advantages Are Increased Depth Of The Liquid Pool, Higher Utilization Rate Of The Filter Cloth, Less Land Occupation, And Lower Operating Costs.
It Mainly Consists Of The Following Parts: Liquid Tank, Waste Cloth Box, Filter Non-woven Fabric (commonly Known As Paper Tape), Transmission Structure, Drum, Signaling Mechanism, Reducer, And Liquid Pump. The Chains And Wire Mesh On The Transmission Mechanism Are In A Circular Arc State, And The Non-woven Fabric Laid On Them Is Also In A Circular Arc State, With A Deeper Depth Of The Liquid Pool. When The Contaminated Liquid Carrying Impurities Flows Onto The Non-woven Fabric Through The Water Flow Buffer Device During Work, The Impurities Are Separated By The Filter Cloth To Form A Filter Cake. The Filter Cake Becomes Thicker And The Liquid Level Of The Contaminated Liquid Rises. The Floating Liquid Level Controller Sends A Signal, And The Reducer Starts To Drag The Filter Cloth. The Dirt And Dirty Cloth Fall Into The Dirty Paper Box, Thus Achieving Automatic Replacement Of The Filter Cloth; After The Filter Cloth Is Updated, The Liquid Level Of The Contaminated Liquid Drops, The Reducer Stops Rotating, And The Machine Enters The Next Filtration Cycle. The Filtered Pure Liquid Is Transported To The Host By A Liquid Pump.
If The Drum Type Paper Tape Filter And Magnetic Separator Are Used In Combination To Form A Secondary Filter, The Effect Will Be Better And The Operating Cost Will Be Lower.
1. Filtering Area: The Filtering Chamber In This Area Is Connected To Chamber I On The Distribution Head, And Chamber I Is Connected To The Vacuum System. The Filtrate Enters The Filtration Chamber Through The Filter Cloth Under Vacuum And Is Discharged Outside The Machine Through The Filter Distribution Head. The Solid Phase In The Filter Slurry Is Trapped On The Surface Of The Filter Cloth, Forming A Filter Cake Layer. To Prevent Solid Settling, A Swinging Stirring Slurry Is Installed In The Filter Tank.
2. Washing And Dehydration Zone: The Washing Solution Is Evenly Sprayed Onto The Filter Cloth Through A Nozzle. Under Vacuum, The Residual Filtrate And Other Impurities Dissolved In The Washing Solution In The Filter Cake Are Squeezed Out And Carried Away, And Then Discharged Through The Distribution Head's Chamber II. To Improve The Dewatering Effect Of The Filter And Prevent A Large Amount Of Air From Flowing Into The Filter Machine, Which Can Reduce The Vacuum Degree, A Leveling Device For The Filter Cake Can Be Installed In The Area, Such As A Press Roller, Press Belt, Etc.
3. Unloading Area: Compressed Air Enters Each Filter Chamber In The Area Through Distribution Head Chamber III, Separating The Filter Cake From The Filter Cloth, And Then The Material Is Scraped Off By A Scraper.
4. Regeneration Zone: To Remove Particles Blocked In The Pores Of The Filter Cloth, Reduce Filtration Resistance, And Allow Compressed Air Or Steam To Enter Each Filter Chamber In The Zone From The Distribution Head VI Chamber, Blow Off Particles On The Filter Cloth, And Regenerate The Filter Cloth.
Simple And Reliable, Automatic Operation;
