Unloading type centrifugal machine with filter bag conducting reciprocating vibration

Abstract

The invention discloses an unloading type centrifugal machine with a filter bag conducting reciprocating vibration. A drum of the unloading type centrifugal machine is of a column-taper-column three-sectional combined type structure, a filter cake is extruded due to the contraction action of the taper section of the drum, and unloading of the filter cake is facilitated. The column section at the tail end of the drum has the guide function for the reciprocating filter bag, has the guide function on the filter cake at the same time, and guides the filer cake to a filter cake unloading port of a chassis of the drum. The unloading type centrifugal machine achieves unloading through the reciprocating vibration of the filter bag, traditional unloading structures such as a scraper and a spiral are completely removed, no mechanical scraping action can play on the filter cake, the shape of crystal particles in the filter cake cannot be damaged, the structure of the crystal particles of the filter cake can be completely kept, and the unloading type centrifugal machine is particularly suitable for being used on occasions where the crystal perfection of the filter cake needs to be kept. In addition, by means of the reciprocating vibration of the filter bag, complete unloading can be achieved, and no filter cake will be left on the filter bag.

Description

Technical field: [0001] The invention relates to a filter bag reciprocating oscillating discharge type centrifuge. Background technique: [0002] At present, there are many kinds of centrifuges in the field of solid-liquid separation. From the automatic unloading methods, there are mainly: automatic scraper unloading, automatic piston unloading, automatic spiral unloading, etc., all of which are mechanically cut and squeezed. The filter cake is peeled off the strainer. These unloading methods will have a mechanical effect on the filter cake and destroy the shape of the crystal particles in the filter cake. In the occasions where the integrity of the crystal particles needs to be ensured, these unloading methods are not applicable. Moreover, these traditional mechanical unloading methods will leave a certain thickness of filter cake on the filter cloth, which will have a negative impact on the next filtration, increase the filtration resistance, or cause pollution to the nex...

Problems solved by technology

These unloading methods will have a mechanical effect on the filter cake and destroy the shape of the crystal particles in the filter cake. In the case where the integrity of the crystal particles needs to be ensured, these unloading methods are not applicable

Moreover, these traditional mechanical unloading methods will leave a certain thickness of filter cake on the filter cloth, which will have a negative impact on the next filtration, increase the filtration resistance, or cause pollution to the next filter cake, etc., and these unloading Both feeding methods need to consume a certain amount of power, which increases the operating cost
