The first end is movable into and out of the housing, and the first end has an opening through a front wall of the first end. There is a heating unit housed in the housing. The heating unit has electrical energy supply conduits from the heating unit to en electrical power source in one embodiment. In addition, the material heater can have a unit for controlling the energy input to the heater.
Description
- This application is a utility application from U.S. Provisional Patent application Ser. No. 62/315,718, filed Mar. 31, 2016 from which priority is claimed.
- Keeping particulate matter warm during the winter months creates a major problem for construction workers.
- It is an age old problem because for cement and mortar to have the proper strength and workability, the temperature needs to be kept above 40° F.
- Early on, sand and other particulates that were used in construction were kept warm by using open fires or by starting fires in cement culverts and piling the particulate material on the culvert.
- There are many problems with such approaches to keeping particulate materials warm. Mostly, the amount of heat from such sources is hard to control. Sand can be scorched and made unusable. Water can easily overheated, causing cement in the mix to set too quickly.
- In addition, such activities are labor intensive because someone has to build and continuously tend the open fires which can pose safety hazards. Further, they hamper productivity by delaying work until materials are heated. Approaches such as giant electric heating pads and, a second approach heats water in a drum that then works like a hot water bottle to heat the sand and finally, a third activity heats water in a chamber and releases steam to heat the sand. There are many variations of these three approaches.
- Such approaches can be found in U.S. Pat. No. 1,631,699 to Selmer which is a sand heating apparatus that comprises a dual sand and water heating element that heats the components simultaneously.
- Mayer, in U.S. Pat. No. 571,382 deals with a sand heater which is a furnace and Mullen, U.S. Pat. No. 965,214, that issued Jul. 26, 1910 deals with a sand heater analogous to the furnace in Mayer.
- U.S. Pat. No. 1,235,802 to Londelius Jr., that issued Aug. 7, 1917 deals with a water and sand heater comprising water heated pipe arrays.
- White, in U.S. Pat. No. 3,176,630 that issued on Apr. 6, 1965, deals with a tent-like structure in which heated water comprising steam is vented through the structure to heat sand contained therein.
- Finally, Olsen, in U.S. Pat. No. 6,408,843 that issued Jun. 25, 2002 deals with a box-like device that is used for ground thawing.
- Thus, what is disclosed and claimed herein is a material heater, consisting essentially of an elongated housing, wherein the housing consists of an outer shell having at least one wall, a first end and a second end, wherein the first end is movable into and out of the housing, and the first and has an opening through a front wall of said first end.
- There is an electrical heating unit housed in the housing. The heating unit has electrical energy supply conduits from the heating unit to an electrical power source.
- In addition, the material heater can have a unit for controlling the energy input to the heater.
