Hydraulic tamping briquette device with heating device

Abstract

The present invention provides a hydraulic tamping briquette device with a heating device, comprising a coal-pressing stand and a coal-distributing trolly. The hydraulic tamping briquette device is characterized in that two pairs of wheels are installed on the coal-pressing stand; the coal-pressing stand is articulated with the coal-distributing trolly via a connection plate; hydraulic motors for driving the wheels are installed at both sides of the coal-pressing stand; a coal-pressing oil cylinder is fixed at the middle of the coal-pressing stand through a flange; guide holes are arranged at both sides of the coal-pressing stand; a guide sleeve and a guide bar are installed on each guide hole; coal-pressing plates are installed at the lower ends of the coal-pressing oil cylinder and the guide bar; the heating device is also installed at the bottom inside the coal-pressing plate; and a locking pothook for fixing the coal-pressing stand is installed at the lower part of both sides of the coal-pressing stand. The hydraulic tamping briquette device with a heating device consumes short time when pressing a piece of briquette, and has high level of mechanization and automation and low production cost; in addition, the heating plate installed at the bottom inside the coal-pressing plate ensures that the coal-pressing plate can not adhere coal dusts when the coal is pressed in winter.

Description

technical field [0001] The invention belongs to coking coal hydraulic tamping equipment, in particular to a hydraulic tamping briquette device with a heating device. Background technique [0002] The stamping coking process is a good way to expand coking resources that has been proved effective by decades of production practice. Its principle is to improve the cohesiveness of coal blending by increasing the density of coal accumulation, thereby improving the quality of coke. Anthracite is a lean coal with a low cohesive index. After blending with the main coking coal, it must be tamped to improve the compactness of the blended coal, ensure the quality of the coke, and make the coke structure dense and less cracked. At present, what tamping briquette mode adopted is the hydraulic tamping device that has coal charging coal box. The hydraulic tamping device mainly includes a coal press frame 1, a press coal cylinder 3 and a guide rod 4 on the coal press frame fixedly connected...

Problems solved by technology

However, the tamping machinery is located outdoors and works under low temperature conditions in winter. When tamping coal cakes, the temperature of the briquetting plate is lower than the outdoor air temperature because the temperature is below the freezing point, which often causes the pulverized coal to freeze in use. The coal pressing board needs to be cleaned manually, which greatly affects the production efficiency of the pressed coal cake, otherwise the pressed coal cake will have serious defects, which will directly and seriously affect the production and quality of coke
