Metallurgical furnace feeding device based on energy storage and material scraping operation

Abstract

The invention discloses a metallurgical furnace feeding device based on energy storage and material scraping operation. The metallurgical furnace feeding device based on the energy storage and material scraping operation structurally comprises an upper hanging plate, a carrying box, a supporting frame, a discharging pipe, a fixing nut, a threaded sleeve, a surface shell, a high-pressure material scraping device, a high-pressure ignition mechanism, a trapezoidal base, a wheel and rod structure, a material containing plate, gas pressure jacking structures and a double-way gas transmission structure. By means of the high-pressure material scraping device, a large quantity of high-temperature gases are absorbed, then are pressurized and transmitted to a small extent and serve as the power of lifting a feeding plate, and therefore energy is further saved, the height of the feeding plate which can be lifted can be larger, and most of raw materials are discharged into a metallurgical furnace;the raw materials on the feeding plate can be subjected to the scraping motion by two scrapers after the feeding plate is lifted, the raw materials can be scraped and completely slide into the metallurgical furnace, and therefore the feeding quantities of the metallurgical cycles are basically equal, and the metallurgical quality is improved; and by the adoption of a ignition high-pressure deviceand a high kinetic energy output mechanism which imitates a spring located inside a pistol, the force of instantaneous popup of the scrapers can be large, the raw materials are more completely scraped advantageously, and the scraping force is larger.

Description

technical field [0001] The invention relates to a metallurgical furnace feeding device based on energy storage and scraping, which belongs to the metallurgical industry and the field of feeding. Background technique [0002] Metallurgical furnaces will generate a large amount of high-temperature gas during operation. In the existing technology, these high-pressure gases are directly used as ordinary gases, and the bottom is less inclined when unloading and feeding, which is easy to cause raw materials to remain on the bottom plate. Not only will the amount of feed material be insufficient, but it will also cause accumulation inside the equipment, so an auxiliary device for complete feeding is urgently needed. [0003] The current technology public equipment has the following disadvantages: [0004] 1. The large amount of hot gas generated during metallurgy is not well used, causing waste of resources, resulting in insufficient power when the feed plate is lifted, and the in...

Problems solved by technology

[0007] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a metallurgical furnace feeding device based on energy storage and scraping materials, so as to solve the problem that a large amount of hot gas generated during metallurgy is not well used, which causes waste of resources and leads to When the plate is lifted, the power is insufficient, and the inclination is not enough to unload all the raw materials into the metallurgical furnace. When the feed plate is feeding, the remaining raw materials will be on the feed plate. When the temperature of the raw material cools down, it will stick to the feed plate. As a result, the amount of material fed next time is affected, and the amount of material entering the metallurgical furnace is not fixed each time, which affects the quality of metallurgy. The scraping device produced on the market is insufficient in power, and the force driven by the motor alone is not enough to solidify The final alloy raw material is scraped off, and the scraping effect is not ideal
