Problems solved by technology

[0003]Semi-coke (also known as semi-coke), the structure is required to be massive, the particle size is generally above 2cm, the color is light black, and the carbon particles are extremely porous. Large surface area, light specific gravity, poor strength, more than 2cm is extremely versatile, less than 2m is called semi-coke powder, semi-coke powder is a high-quality coal type, and the output is huge in the production area. It cannot be properly optimized and utilized, so it can only be given away or sold at a price much lower than that of ordinary anthracite, which greatly wastes high-quality resources

preparation example Construction

[0020] The preparation method steps of the adhesive are:

[0021] Grind thiourea, polypropylene, amide, and borax into subdivisions of less than 80 mesh, and put the ground subdivisions, corn starch, dextrin, borax, and 502 rubber powder into the dry powder mixer and mix evenly. The finished product of the adhesive dry powder should be packaged with moisture-proof inner and outer bags, and stored in a cool and dry place;

[0022] When in use, add 30kg of water and 70kg of binder dry powder to the stirred reactor. After stirring it into a thick and viscous slurry, add 850Kg of water to dilute the slurry into a liquid state. When it is completely liquid, slowly add it diluted with 30kg water 20kg of sodium hydroxide solution; it reacts into a brown viscous liquid during stirring, ready-made blue charcoal powder is used as a binder to replace coke in closed calcium carbide production.

[0023] Quality requirements and molding process standards of main materials and auxiliary materials:...

Embodiment 1

[0028] A type of coke used for the production of closed calcium carbide with blue charcoal as the main raw material, including the main material of blue charcoal with fixed carbon of 80%, gas fat coal or coking coal auxiliary material and the reinforcing and bonding of the blue charcoal Binder

[0029] The described type of coke using blue charcoal powder as the main raw material for closed calcium carbide production is characterized by its production method. The specific steps are as follows:

[0030] First add 65% of the main ingredients, add 35% of the auxiliary materials and mix them evenly in the mixing mixer, and then add the liquid amount of the binder to the raw and auxiliary materials being stirred according to the ratio of 150-180kg binder per ton of blue carbon powder Continue to stir until the mixed materials are caught by hands and form a mass without sticking hands, and then sent to the molding machine for molding. The molding particle size is 2-3cm in diameter. The ...

Embodiment 2

[0037] A type of coke used in the production of closed calcium carbide with blue charcoal as the main raw material, including the main material of blue charcoal with fixed carbon of 83%, gas fat coal or coking coal auxiliary material, and the reinforcing and bonding of the blue charcoal Binder

[0038] The described type of coke using blue charcoal powder as the main raw material for closed calcium carbide production is characterized by its production method. The specific steps are as follows:

Abstract

The invention discloses a binder for preparing formed coke by taking semi coke powder as a main raw material. The binder comprises the following raw materials in percentage by weight: 65-75% of corn starch, 25-15% of dextrin, 4-6% of borax, 3-1% of 502 rubber powder, 2-1% of polystyrene amide and 1-2% of thiourea, totally 100%. The raw materials are ground to obtain dried powder of the binder. According to the dried powder of the binder used, 20kg of sodium hydroxide and 910kg of water are added into every 70kg of special dried powder binder to synthesize the liquid binder. The invention provides a binder for producing formed coke for airtight calcium carbide production by taking semi coke powder as the main raw material. The binder is used for binding semi coke powder, so that the semi coke powder is greatly optimized in use, thereby improving the market benefit and value, saving the coke resource, and meanwhile, greatly lowering the calcium carbide production cost. Therefore, the binder is very remarkable in economic and social benefits.

Description

technical field [0001] The invention relates to the field of molded coke for calcium carbide production, in particular to a binder for molded coke preparation with semi-coke powder as the main raw material. Background technique [0002] Semi-coke, semi-coke is made of high-quality Jurassic clean coal abundant in Shenfu Coalfield or high-quality coal similar to Shenfu long-flame coal (such as lean coal, weakly caking coal, etc.), as a new type of carbon The material, with its characteristics of high fixed carbon, high specific resistance, high chemical resistance, low ash content, low aluminum, low sulfur and low phosphorus, is widely used in calcium carbide, ferroalloy, ferrosilicon and silicon carbide to gradually replace metallurgical coke The production of such products has become an irreplaceable carbon material. [0003] Semi-coke (also known as semi-coke), the structure is required to be massive, the particle size is generally above 2cm, the color is light black, the ...
