Abstract
The invention belongs to the technical field of briquettes, and particularly relates to industrial briquettes with a simple process and a preparation process thereof. The industrial briquettes consist of the following raw materials in part by weight: 90 to 96 parts of pulverized coal, 1 to 2 parts of setting accelerator (calcium aluminate), and 2 to 8 parts of adhesive. The preparation process comprises the steps of: (1) firstly, crushing lump coal into the pulverized coal with sizes less than 2.5mm; (2) then mixing the pulverized coal obtained through the crushing, the adhesive and the setting accelerator (calcium aluminate) according to the proportion, and then stirring the mixture uniformly; and (3) cold-pressing the mixture into a needed shape, and naturally drying or drying to obtain the industrial briquettes. The industrial briquettes and the preparation process take fire coal as a main raw material; and the industrial briquettes have the simple preparation process, so the problem of complicated process of original briquettes is greatly simplified, the production cost is greatly reduced, and various benefits can be increased. Therefore, the industrial briquettes have the remarkable characteristics of simple process, remarkable waterproof property, and high firm strength. The industrial briquettes have considerable market application prospect, and are suitable for mass popularization and application.
Description
Technical field
The invention belongs to a kind of technical field of moulded coal, relate in particular to simple industrial shaping coal of a kind of technology and preparation technology thereof.
Background technology
Employed industrial shaping coal has many types on the domestic market at present, but it is poor that great majority all exist water-repellancy, and in transfer processes such as transportation in case after being subjected to the drenching or soak of rainwater, moulded coal has promptly reduced intensity, make it in transportations such as carrying, very easily cause serial problems such as fragmentation, also brought very big difficulty therefore for the storage of moulded coal and transportation.Because these existing moulded coal water resistance aspects exist weak point, so how those skilled in the art constantly may improve the water-repellancy of moulded coal in research.But some that are provided have the moulded coal of water resistance still more or less exists complex process, starting material problem how, this makes product cost improve much virtually, therefore though can waterproof, but because the raising of its price and cost, can't introduce to the market in a large number also always, can't satisfy people now to moulded coal price and qualitative requirement.
Summary of the invention
The present invention be directed to the problem that prior art exists, simple industrial shaping coal of a kind of technology and preparation technology thereof are provided, it has the simple distinguishing feature of technology.
The present invention realizes by the following technical solutions:
A kind of industrial shaping coal, it is to be made of following raw materials by weight portion ratio:
Coal dust: 90-96,
Accelerating chemicals calcium aluminate 1-2,
Binding agent 2-8.
Described a kind of industrial shaping coal is to be made of following raw materials by weight portion ratio:
Coal dust: 90,
Accelerating chemicals calcium aluminate 2,
Binding agent 8.
Described a kind of industrial shaping coal is to be made of following raw materials by weight portion ratio:
Coal dust: 96,
Accelerating chemicals calcium aluminate 2,
Binding agent 2.
Described a kind of industrial shaping coal is to be made of following raw materials by weight portion ratio:
Coal dust: 95,
Accelerating chemicals calcium aluminate 1,
Binding agent 4.
The preparation technology of described a kind of industrial shaping coal is:
(1) at first lump coal is crushed to less than 2.5mm;
(2) again with above-mentioned coal dust after crushed with stir after binding agent and accelerating chemicals calcium aluminate mix according to the above ratio;
(3) mixture is cold-pressed into desired shape, after seasoning or the oven dry, promptly.
A kind of industrial shaping coal of the present invention and preparation technology thereof, it is to be main raw material(s) with the fire coal, owing to have simple preparation technology, has simplified the problem of original moulded coal complex process greatly, greatly reduces production cost, and can increase every income.Therefore, the present invention has the distinguishing feature that technology is simple, water resistance remarkable, the labor tenacity is high.Have considerable market application foreground, be fit to large-scale popularization and use.
