Stepped sealing system for preventing exit of fluid material from mixer that is utilized for production of ready-mixed concrete, has connection elements for assembling/disassembling bolts to facilitate prestressing of sealing element

摘要

The system (Z) has connection bolts (25) for preventing compression of an interior case (2) on a front sealing element (3). A joint support (17) fixes the front sealing element on a step shape of an external case (7). A slave bolt system (11) assembles the interior case and the external case such that the system is assembled and maintained in a workshop environment. Connection elements assembles or disassembles the connection bolts to facilitate prestressing of the front sealing element and assembling/disassembling of the interior case with respect to the external case.
