PLD Pull Bag Discharge Centrifuge 

Working Principle 

Scraper acts in unloading process and most materials are discharged out of machine through the discharge port at the bottom of basket under the action of scraper, while the residual materials are completed cleared by the vibration generated by the automatic pulling mechanism inside basket. 

Main Features 

Variable-frequency speed governing, and automatic control; it has the all advantages of common vertical scraper discharge centrifuge; the lowering and resetting of pulling bag is automatically operated; filter bag can move upward and downward in basket and generate vibration to completely clear residual filter cake; the large flip cover or full-flip housing can be selected according to requirements; residual filter cake clearing device is optional; the external / internal pull bag drive mechanism is optional. 

Working Principle 

Cylinder drive is adopted, which can drive lower edge of filter bag to make reciprocating motion quickly, and generate vibration effect to filter bag and completely clear the residual materials. The special material baffle mechanism is set between the bottom of pull bag hood and discharge port. It's proven by practices that it can effectively stop materials entering into reverse side of filter bag during the acting process of pull bag, and scraper will not scratch filter bag. The cylinder of pull bag rotates synchronously with main shaft pulley without any relative motion or vulnerable parts. 

Selection of pull bag drive method: 

1. Internal cylinder: the cylinder driving pull bag is set under the belt of main shaft and directly connected with pull rod. Advantage: compact structure; simple and beautiful appearance; convenient to replace belt. 

2. External cylinder: the cylinder driving pull bag is set besides the bearing block and connected with pull bag shaft through connecting rod. Advantage: the motion speed of pull bag is high.
