Holding Tank Heating System

Abstract

A portable toilet satellite station comprising an enclosure having a front wall, rear wall, side walls and a roof. The enclosure further having an inside area at least partially defined by the front wall, rear wall, side walls and the roof. The portable toilet satellite station further including a toilet having a holding tank. The portable toilet satellite station further including a heating system in communication with the holding tank. The heating system is capable of producing warmed air that can be directed through the heating pipe and into the holding tank and preferably also the inside of the enclosure to warm a user.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application Ser. No. 61 / 030,274, filed Feb. 21, 2008, entitled “Holding Tank Heating System,” the disclosure of which is hereby incorporated by reference.BACKGROUND OF THE DISCLOSURE[0002]1. Field of the Invention[0003]The present invention relates generally to heating systems for sewage holding tanks. Particularly, the present invention relates to heating systems for portable toilet satellite stations or above ground sewage holding tanks. More particularly, the present invention relates to a heating system for a portable toilet satellite station holding tank that warms the holding tank and the inside area of a portable toilet satellite station to additionally warm users.[0004]2. Description of the Related Art[0005]A portable toilet, also known as a port-a-potty, is a modern, portable, self-contained outhouse typically manufactured of molded plastic often used as a temporary toilet for construction sites,...

AI Technical Summary

Benefits of technology

[0014]The toilet includes a holding tank preferably having a vent leading outside of the enclosure to vent gases produced by sewage stored in the holding tank. To generally prevent freezing of the sewage within the holding tank and water within the water tank, the portable toilet includes a heating system, such that the holding tank can be heated. In the most preferred embodiments, the heating system further includes an interior vent that at least partially directs heated air produced by the heating element into the interior of the enclosure.

Problems solved by technology

Keeping sewage at a temperature above freezing can be particularly challenging in areas where the temperature outside is below freezing.

Using salt brine is labor intensive because of the need to store enough salt and to mix the brine in effective proportions.

Being a petroleum product, the cost of methanol is increasing daily.

If the portable toilet owner is dumping the raw sewage in a rural environment, methanol has a negative effect on environmental quality and may be considered a pollutant.

The disposing of any methanol, wherever, has a negative environmental effect, as city sewage plants cannot remove this pollutant in their refining processes.

Traditional anti-freeze is also expensive and is often cost prohibited.

In addition, this method requires extra effort to dispose of legally.

To heat the portable toilets, many employers rely on known portable space heaters; however, these are easily removed from the portable toilet and therefore, the space heaters are often missing for various reasons.

This provides for a time consuming and costly responsibility of continuing to maintain government regulatory standards.
