Far infrared coal scuttle heater

Abstract

The invention discloses a far infrared coal scuttle heater. A plurality of outer shells are arranged on the outer wall of a bottom coal outlet of the coal scuttle side by side, a coil-shaped electricheating pipe is arranged in a heating cavity, tightly attached to the wall part of the coal outlet, of a middle clapboard of an inner cavity of each outer shell, and a temperature measuring element isarranged in the center of the electric heating pipe. The end parts of the temperature measuring element and the electric heating pipe vertically penetrate through the middle clapboard and a top plateof the outer shell, and then are connected with an explosion-proof junction box, and a heat-insulating cavity at the other side is filled with a heat-insulating material. A control circuit of a far infrared control cabinet controls the electric heating pipe to operate regularly, the bottom coal outlet of the coal scuttle is preheated to unfreeze before a production line is started, and a scuttleopening blockage is avoided to guarantee that coal flows smoothly in the coal scuttle. The far infrared coal scuttle heater is simple in structure and good in unfreezing effect, is convenient to operate, saves time and labor, is safe and reliable, can heat uniformly, and enable the production efficiency to be improved. The far infrared control cabinet can also be combined with a remote automaticcontrol system to adapt to the intelligent control requirements.

Description

technical field [0001] The invention relates to a far-infrared coal hopper heater. Background technique [0002] The coal in the coal washing plant is transported to the next process through the pipeline after being washed. A coal hopper is installed at the end of the pipeline, and the coal hopper door switch is used to control whether the coal is unloaded or not; after the coal is washed, it contains a large amount of water. The weather, especially in winter, is easy to freeze after parking, causing the mouth of the hopper to be blocked, and the coal cannot be discharged normally after the door is opened; in the traditional method, the bottom of the coal hopper is manually grilled with an open fire to defreeze, which is inconvenient to operate, takes a long time, and heats unevenly , the thawing effect is not good, and there are potential safety hazards, which affect the production efficiency. Contents of the invention [0003] The technical problem to be solved by the p...
