Heated belt scraper bar apparatus

Abstract

A heated scraper bar assembly for a conveyor belt system having a reservoir configured to retain a liquid. A heating element is configured to heat the liquid in the reservoir. A scraping system is affixed to the reservoir and in thermal communication with the liquid. The scraping system increases in temperature through the thermal communication with the heated liquid to prohibit frozen process materials from sticking to the scraping system. The scraper bar assembly is useful for removing frozen debris from an active conveyor belt system.

DETAILED DESCRIPTION

(7) As discussed above, embodiments of the present disclosure relate to a scraper and more particularly to a heated belt scraper bar as used to improve the use of conveyors.

(8) Generally, the oil heated scraper bar assembly is preferably heated by a heater probe submerged in an oil within a reservoir of the heated scraper bar assembly. The heated scraper bar assembly prevents materials from freezing around the scraper bar and causing the scraper to not function properly. When the scraper does not scrape material from the belt of a conveyor belt system it causes material to fall from the belt onto the ground, thereby making a mess. By heating the scraper bar, and the attached scraper pads, as disclosed herein, material is prevented from freezing to the scraper bar assembly and causing material to fall to the ground. Ensuring the scraper is functional reduces downtime and manual labor spent cleaning up fallen material.
