PLD series bag-type scraper lower discharge centrifuge is a new product independently developed by our company with complete independent intellectual property rights. On the basis of maintaining the main functions of solid-liquid separation and scraper unloading of LGZ series products, the machine has added the function of removing residual cake layer by pulling bag, and the removal rate can reach over 99%. The cross-mixing of the separation of products between different batches is avoided, and the influence of the residue filter cake layer on the filtration rate is solved. Mainly used in solid-liquid separation processes in pharmaceutical, food, MSG, chemical and other industries.
working principle:
The material to be separated is added into the rotating drum of the high-speed rotating machine through the feeding tube. Under the action of the centrifugal field, the material is filtered by the filter cloth, the liquid phase is discharged through the liquid discharging pipe, and the solid phase is trapped in the rotating drum. When the material is topped up, the feed is stopped and the filter cake is washed while the wash liquid is filtered out. The centrifuge continues to rotate and the filter cake is dried. After the filter cake reaches the separation requirement, the centrifuge is decelerated, and the filter cake is scraped off the bottom of the machine through the scraper. The centrifuge is further decelerated, and the pneumatic bag pulling device reciprocates up and down, and the residual filter cake is shaken off to completely remove the filter cake.
PLD centrifuge working procedure:
Main features of PLD centrifuge:
In addition to all the main features of the LGZ centrifuge, this machine also has the following features:
The residual filter cake is removed by a pull bag. Through the up and down reciprocating pulling of the pneumatic bag pulling device, all the filter cakes discharged from the scraper are completely removed, thereby achieving complete unloading and filter cloth regeneration.
◇ Detachable drum control board design, self-locking is reliable, filter cloth replacement is convenient and easy.
◇External cylinder + connecting rod drive design, reliable operation.
◇The fully enclosed hopper design completely separates the material from the transmission parts.
PLD centrifuge main configuration instructions:
◇Structural structure: large open cover, fully open cover and flat cover
◇ cloth method: swash plate distributor, side cloth tube, intermediate cloth tube, material level inspection
Measuring device
◇ scraper discharge: pneumatic, hydraulic, liquid sputum device
◇Motor drive: ordinary motor, variable frequency motor, explosion-proof motor

PLD pull bag replacement operation is fast:
Flip open (hydraulic action)
The filter bag retaining ring snap ring is removed, the liquid retaining plate fixing pin is removed, and the liquid intercepting plate is lifted out
The lower ring of the filter bag is removed, and the old filter bag is taken out.
New filter bag loading, filter ring under the filter ring tension
The liquid trap is loaded, the liquid retaining plate is fixed, and the filter bag is closed.
Flip closed, locked
Check the filter bag fitting status and check the bag movement check
