Abstract
A method and apparatus including a connection element for transfer of knock- or impact-beating energy from a mechanically, hydraulically or pneumatically driven knock- or impact-beating device upon heating or cooling surfaces to be cleaned intermittently. The heating or cooling surfaces are installed in a container or vessel driven and operated on the gas side at an elevated pressure compared with respect to the atmospheric environmental pressure. The heating or cooling surfaces have external flow of hot, dust-laden gases thereagainst. The knock- or impact-beating device is fastened externally of the pressure container. In the region of the knock- or impact-beating energy transferring from the knock- or impact-beating device as far as to the heating or cooling surface to be cleaned there is applying of a counter gas pressure during energy transfer as to the higher container-gas pressure otherwise preventing or precluding the energy transfer; the container-gas pressure is countered with a gas pressure of equal magnitude which is communicating or non-communicating with respect thereto. A pressure equalizing or balancing connection element is inserted or connected between the mechanically, pneumatically or hydraulically operated and driven knock- or impact-beating device and the heating or cooling surface to be cleaned. This connection element collectively includes the housings, the energy transfer element and a shut-off or blocking element. A compensating or equalizing passage connecting both of the pressure chambers of the pressure container is provided with the energy transfer element and sealing elements are provided to separate the pressure chambers from each other and to seal against the housings.
