Problems solved by technology

[0004] At present, there are very few briquettes that are truly converted into productivity and can create wealth for enterprises, mainly due to the disadvantages of unsatisfactory combustion effects.
The entire briquette industry, including national-level briquette research institutions and professional manufacturers of briquette equipment, does not have a strict standard for the particle size of raw coal, which is pulverized with a hammer mill, and the pulverized particle size is relatively large. The ratio of briquettes to 40 meshes is relatively large. Because of the fear of coal briquettes being scattered during the combustion process, some coal slime and inorganic impurities with high heat resistance strength have to be added to the briquettes to maintain the heat strength. The excessive pursuit of heat strength by enterprises hinders the briquettes. burning effect

Embodiment 1

[0018] 100 kg of natural pulverized coal is pulverized into 100 mesh by ultra-fine pulverizer, mixed with 20 kg of glutinous rice noodles, and the pressure of the forming machine is 300 kg / cm2. Bake for 20 minutes, then raise the temperature to 300°C and bake for 40 minutes to get the finished product. The cold strength of the finished product is 80 kg / single ball.

Embodiment 2

[0020] 100 kg of lump coal leftovers are pulverized into 150 mesh by ultra-fine pulverizer, mixed with 23 kg of millet noodles, and the molding machine pressure is 300 kg / cm2. Bake at 100°C for 20 minutes, then raise the temperature to 300°C and bake for 40 minutes to get the finished product. The cold strength of the finished product is 85 kg / single ball.

Embodiment 3

[0022] 100 kg of natural pulverized coal is pulverized into 270 mesh by ultra-fine pulverizer, mixed with 25 kg of glutinous rice noodles, and the pressure of the forming machine is 300 kg / cm2. Bake for 20 minutes, then raise the temperature to 300°C and bake for 40 minutes to get the finished product. The cold strength of the finished product is 90 kg / single ball.

Abstract

The present invention is one kind of briquette and its making process. The briquette is made with coal powder and adhesive in the weight ratio of 100 to 20-25, and features the coal powder of grain size 100-270 mesh and the adhesive is powder of glutinous rice or millet. The making process of the briquette includes superfine crushing coal, mixing the coal powder with adhesive through stirring, rolling into flat circular or square form, and drying. The briquette has the advantages of no pollution to air, capacity of replacing lump coal, high cold strength, high burning effect, etc.

Description

(1) Technical field [0001] The invention relates to a kind of coal, in particular to a kind of molded coal and its preparation method. (2) Background technology [0002] With the rapid development of social economy, the amount of lump coal is increasing, and the proportion of fine coal mined with modern equipment has increased accordingly, resulting in a shortage of lump coal, the contradiction between supply and demand has become increasingly prominent, and the price of lump coal has been rising all the way. However, fine coal and natural pulverized coal have large resources and a small range of use, resulting in a slow rise in prices. The current price of lump coal is about twice as high as that of fine coal. There are only two ways to solve this contradiction. The first is to open source, and the second is to make cheap fine coal into high-quality briquette to replace lump coal. Lump coal resources are inherently scarce, and open source is impossible, so producing high-q...
