Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuges and relates to a flat-plate centrifuge capable of preventing filter bag residue from accumulating. Background Art

[0002] A plate centrifuge is a platform-type centrifuge with a welded outer shell and platform. The cover and housing utilize a flanged, quick-opening mechanism, assisted by a mechanical balancer. As a common solid-liquid separation device, plate centrifuges are widely used in the chemical, pharmaceutical, and food industries. Their operating principle is to separate solid particles from liquids through the centrifugal force generated by high-speed rotation. However, in actual use, if a plate centrifuge fails to effectively prevent the accumulation of filter bag residue, a series of problems may arise.

[0003] As residue accumulates in the filter bag, the filter area gradually decreases, increasing the resistance to liquid passing through the bag and affecting the separation efficiency of the centrifuge. This may not only lead to a decline in product quality, but also increase production costs and time.

[0004] The accumulation of debris in the filter bags can lead to clogging, which in turn can cause the centrifuge to overload. Long-term overloaded operation can not only damage centrifuge components but also cause motor overheating and bearing wear. Therefore, there is an urgent need for a flat-plate centrifuge that can prevent filter bag residue accumulation to solve these problems. Utility Model Content
