Abstract
A heating device for a hopper collecting dust and discharging the dust to the bottom is disclosed. The heating device of the hopper is installed in a structure that surrounds the outside of the plate of the hopper, and has a predetermined thickness and a predetermined portion is cut out. A fin tube device installed in the incised quartz portion; And an auxiliary insulating material that covers the fin tube device and is coupled with the heat insulating material. In this embodiment of the present invention, the inside of the hopper can be prevented from moisture or condensation, and even if a problem occurs in the heating device for preventing condensation, it is possible to easily repair the auxiliary insulating material after removing the auxiliary insulating material with the handle. And the installation cost can be reduced because the electric hot wire or the steam pipeline does not need to detect the entire hopper.
Description
BACKGROUND OF THE
Dust collectors are used to collect dust discharged from a dust generating process such as general coal or heavy oil combustion process, waste incinerator process, cement manufacturing industry, and steelmaking process, clean it with clean air, and discharge it to the outside.
The dust collector filters the polluted air to filter the dust, and discharges clean air to the outside. The upper spray nozzle injects the compressed gas into the bag filter to desorb dust collected in the bag filter, Prevents clogging of filter and improves purification efficiency.
A hopper is installed at the lower part of the bag filter to store the removed dust for a predetermined period of time and is discharged to the outside by a discharge device at the lower part thereof.
Conventionally, when humidity or condensation occurs due to the temperature difference between the inside and the outside of the hopper, low-temperature corrosion occurs in the hopper steel plate, and the dust is condensed and can not be smoothly discharged to the bottom.
Accordingly, in order to remove moisture or prevent condensation, conventionally, an electric hot wire or a hot steam pipe was wound around the hopper to keep the temperature constant, and the outside of the hopper was wrapped with a heat insulating material and kept warm.
The dust is dropped to the bottom by using the vibration of the motor or periodically applying an impact using an air knocker to prevent dust from accumulating inside the hopper.
However, in the past, such an impact causes a short circuit of the electric hot wire or breakdown of the hot steam pipe.
When such a failure occurs, it is conventionally necessary to tear off all of the heat insulating material and short-circuit the electric hot wire or to locate and repair the rupture part of the steam pipe, and it takes a lot of time and requires a lot of replacement cost.
SUMMARY OF THE INVENTION The present invention has been made in an effort to solve the problems of the prior art, and it is an object of the present invention to provide a heating apparatus for a hopper which prevents moisture from getting inside or condensation inside the hopper.

Wherein the heat insulating material is formed in such a manner that a predetermined area or less from a portion where the heating device is installed forms a predetermined space with the plate of the hopper.
The heating device may include a terminal for increasing the heat radiation effect in the form of a fin tube and capable of performing electrical connection, or an inlet through which steam is input and an outlet through which steam is output. And is conducted through the space of the second electrode.
And the contact portion of the heat insulating material, which is separated from the plate of the hopper so as to form a predetermined space, is formed in the form of a metal mesh.
