LGZ/PGZ series centrifuge is a kind of centrifugal separation machine with high-tech inclusion. It can be selected in a variety of configurations and can realize automatic program control. It has aseptic hygiene, sealed explosion-proof, multiple safety protection, multiple configuration options, etc. Features, widely used in pharmaceutical, fine chemical, food and other industries.
working principle:
The lower discharge centrifuge of the scraper is a vertical automatic filter centrifuge. The motor drives the drum to rotate at a high speed through the belt. The material to be separated enters the drum of the high-speed rotating centrifuge through the feeding system under the control of the pre-programmed program. Under the action of the centrifugal force field, the material is filtered through the filter medium (filter cloth/filter), the liquid phase is discharged out of the machine through the liquid outlet tube, and the solid phase is trapped in the drum. - The material detecting device detects the material filling position in real time, and stops feeding when the filter cake in the drum reaches the machine-specified loading amount. The filter cake is then washed and dried. After the filter cake reaches the deliquoring requirement, the centrifuge is lowered to the scraping speed, and the scraper device
The filter cake is scraped under the control of liquid (gas) and discharged through the discharge port at the lower part of the centrifuge.
The main purpose:
It is mainly used for solid-liquid separation of suspensions containing solid phase particles, and also for solid-liquid separation of fibrous materials. Especially for the separation of high viscosity, fine particle size, toxic, flammable and explosive materials. Such as antibiotics, vitamins, pharmaceutical intermediates and other pharmaceutical products, salt, monosodium glutamate, food additives, starch, sugar, chemical flavorings and other foods, ammonium sulfate, gypsum, Glauber's salt, copper sulfate, potassium chloride, borax, dyes, pigments, Chemical raw materials such as resins and pesticides, as well as solid-liquid separation in industries such as mining and environmental protection. Centrifuge automation is high, throughput
Large, remote control is possible.
work process:
Main features of LGZ/PGZ centrifuge:
◇Flat-type structure, low center of gravity, stable operation; four-point support, liquid damping, no foundation installation, improve vibration isolation and vibration damping performance
◇ Free-standing swash plate cloth device with uniform feeding and control.
The helium gas recoil and gas-assisted scraper device minimizes residual filter cake for regeneration of the filter cloth.
◇ Nitrogen protection system for explosion-proof applications.
◇ Large clamshell or full clamshell structure, a cleaning device is installed in the inner cavity of the centrifuge, and the centrifuge is cleaned on-line to avoid cross-contamination of the product.
◇Multiple safety protection devices: over vibration protection, over current protection, temperature control protection, material layer control, blade stroke protection, open cover protection machinery and electrical interlock protection, various warning and warning signs.
◇ PLC program control, touch screen, inverter control, energy consumption braking, feedback braking, device fault self-diagnosis, automatic man-machine interface control, DCS control interface.
