RU28662U1 - Heating system for toilet tank-collection cars - Google Patents

Description

made in the form of semiconductor heat generators, the electrical terminals of which are connected to the electric heaters of the tanks-collectors.

The introduction of distinctive features in the utility model can significantly simplify the design of the system, increase its reliability and dramatically reduce operating costs.

Brief Description of the Drawings

The essence of the utility model is illustrated by the scheme shown in figure 1, where the corresponding positions denote:

1- heat source (boiler) of the car,

2- fecal collection tank,

3- electric heaters of the collection tank,

4- semiconductor heat and power generators.

Best performance

The device contains a heat source - a liquid-fuel boiler for carriage 1, to the hot surfaces of which (boiler structures or heating pipes) semiconductor heat-electric generators 4 are attached, the electrical leads of which are connected to electric heaters 3 of fecal tanks of collectors 2 of the carriage's toilet system.

Device operation

During the operation of the boiler for liquid heating of the car 1, its heat is transferred in a contact way to the junction of the semiconductor heat generators 4. As a result, a potential difference arises on its electrical terminals, which is fed by wire to the electric heaters 3 of the fecal storage tanks 2 of the car, where electric energy is converted into heat for heating the latter. Such a system is practically maintenance-free and operates automatically, since the lower the outside temperature, the higher the temperature in the boiler for liquid heating.

Industrial applicability

Technical documentation is developed, an experimental model of a utility model is manufactured.
