Description

Technical Field

[0001] This utility model relates to the technical field of gasifier equipment, specifically a coal feeding device for a gasifier. Background Technology

[0002] When a liquid evaporates in a confined, enclosed space, liquid molecules pass through the liquid surface and enter the space above, becoming vapor molecules. Because these vapor molecules are in turbulent thermal motion, they collide with each other, the container walls, and the liquid surface. During collisions with the liquid surface, some molecules are attracted by the liquid molecules and return to the liquid. At the beginning of evaporation, the number of molecules entering the space exceeds the number returning to the liquid. As evaporation continues, the density of vapor molecules in the space increases, thus increasing the number of molecules returning to the liquid. When the number of molecules entering the space per unit time equals the number returning to the liquid, evaporation and condensation are in dynamic equilibrium. At this point, although evaporation and condensation are still occurring, the density of vapor molecules in the space no longer increases; this state is called saturation. A liquid in a saturated state is called a saturated liquid, and its vapor is called dry saturated steam. Existing steam generation equipment relies on coal for heating, but coal feeding equipment has shortcomings, such as:

[0003] The automatic coal feeding device described in Publication No. CN202709160U includes a support frame, on which a belt conveyor mechanism is mounted. The belt conveyor mechanism has a lower horizontal conveying section, an inclined conveying section, and an upper horizontal conveying section. Multiple baffles are fixed on the surface of the belt of the belt conveyor mechanism, with gaps between adjacent baffles. A motor is mounted on the support frame, and the output shaft of the motor is connected to the drive shaft of the belt conveyor mechanism. A frequency converter is mounted on the support frame and is electrically connected to the power supply terminal of the motor. Because this device uses a belt conveyor mechanism to transport coal, if the feed position of the boiler equipment is too high during use, the conveying line must be lengthened to ensure stable material transport, resulting in an excessively large footprint. Utility Model Content

[0004] The purpose of this utility model is to provide a coal feeding device for a gasifier, in order to solve the problem mentioned in the background art that the existing equipment on the market uses a belt conveyor to transport coal. During use, if the feed position of the boiler equipment is too high, the conveyor line must be lengthened to meet the stable transport of materials, resulting in an excessively large footprint.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal feeding device for a gasifier, comprising a supporting base plate, a support column, a motor, a gearbox, and pulleys;
