Apa Itu Filter Drum Vakum Rotary?
Filter Drum Vakum Rotary (RDVF), juga dikenal sebagai Filter Vakum Drum Rotary, adalah mesin pemisahan padat-cair kontinu yang menghilangkan cairan dari bubur di bawah vakum. Selama rotasi drum, filtrasi, pencucian cake, dewatering, pengeringan, dan pembuangan diselesaikan dalam siklus kontinu, sehingga cocok untuk proses filtrasi industri berkapasitas tinggi.
Peralatan ini memiliki karakteristik operasi kontinu, kinerja filtrasi yang stabil, dan pembuangan cake otomatis, sehingga cocok untuk aplikasi pertambangan, pengolahan mineral, pengolahan air limbah, kimia, batu bara, dan industri lainnya. Zhongyi Mining menyediakan solusi filter vakum drum rotary yang disesuaikan sesuai dengan sifat material, kebutuhan kapasitas, dan kondisi proyek, dengan dukungan yang mencakup desain peralatan, manufaktur, instalasi, dan commissioning.
Prinsip Kerja
Filter Drum Vakum memisahkan padatan dari bubur melalui proses filtrasi vakum kontinu. Komponen utama meliputi drum berputar, kain filter, sistem vakum, katup distribusi, dan mekanisme pembuangan. Selama operasi, drum berputar sebagian terendam dalam tangki bubur, dan tekanan vakum menarik cairan melalui kain filter sementara partikel padat tetap berada di permukaan drum untuk membentuk cake filter.
Proses filtrasi meliputi pengumpanan bubur, filtrasi vakum, pembentukan cake, pencucian dan pengeringan, serta pembuangan cake filter. Sistem pembuangan yang berbeda dipilih sesuai dengan sifat material, termasuk pembuangan scraper untuk aplikasi umum, pembuangan roll untuk cake lengket, pembuangan string untuk cake tipis yang rapuh, dan pembuangan belt untuk cake basah yang memerlukan pencucian kain filter. Proses kontinu ini memberikan pemisahan padat-cair yang stabil untuk aplikasi pertambangan, kimia, air limbah, dan industri.
Komponen Utama Filter Drum Vakum
Filter Drum Vakum Rotary mencapai pemisahan padat-cair kontinu melalui operasi terkoordinasi dari drum berputar, kain filter, katup distribusi, tangki bubur, dan sistem pembuangan. Zhongyi Mining merancang dan memproduksi filter drum vakum dengan struktur komponen yang dioptimalkan untuk memastikan kinerja filtrasi yang stabil, operasi yang andal, dan solusi yang disesuaikan untuk berbagai aplikasi industri.
Drum Berputar
Unit filtrasi utama, dilapisi kain filter dan dibagi menjadi ruang filter. Berputar melalui zona filtrasi, pencucian, pengeringan, dan pembuangan.
Katup Distribusi
Mengontrol aliran vakum dan udara di setiap ruang filter untuk mempertahankan siklus filtrasi kontinu.
Kain Filter dan Sistem Pengikat
Memisahkan padatan dari cairan dengan memungkinkan cairan melewatinya sementara menahan partikel padat untuk membentuk cake filter.
Tangki Bubur
Menyimpan bubur dan menjaga suspensi material yang seragam selama filtrasi.
Sistem Pembuangan Cake
Mengeluarkan cake filter dari permukaan drum melalui metode pembuangan scraper atau tiupan udara balik.

FAQs
What is a Rotary Vacuum Drum Filter?
A Rotary Vacuum Drum Filter is a continuous solid-liquid separation machine that uses vacuum pressure to separate liquid from slurry. The rotating drum covered with filter cloth collects solid particles, forms filter cake, and completes filtration, drying, washing, and discharge during continuous operation. It is widely used in mining, metallurgy, chemical, and industrial filtration processes.
How does a Rotary Vacuum Drum Filter work?
The equipment works by rotating the drum through a slurry tank while applying vacuum pressure inside the filter chambers. Liquid passes through the filter cloth, and solid particles remain on the drum surface to form filter cake. The cake is then dried and removed through scraper, roller, string, or belt discharge systems.
What materials can be processed by a Rotary Vacuum Drum Filter?
Rotary Vacuum Drum Filters are mainly used for slurry materials requiring continuous dewatering and filtration. Typical applications include iron ore concentrate, copper concentrate, tailings, coal slurry, chemical slurry, industrial sludge, and other solid-liquid separation processes.
What factors should be considered when selecting a Rotary Vacuum Drum Filter?
Selection depends on material characteristics, processing capacity, and filtration requirements. Important factors include particle size, solid concentration, slurry viscosity, corrosiveness, required cake moisture, washing requirements, and operating conditions. Zhongyi Mining provides customized configurations based on actual project requirements.
