Production of fuel and metal briquettes with a hydraulic gear press

The device relates to the production of fuel briquettes for domestic and industrial needs and to obtain metal briquettes for use in refractory production, non-ferrous and ferrous metallurgy.

A device for the production of briquettes from peat, lignin, sawdust, wood chips and wood dust and from sludge from ferrous and non-ferrous metallurgy, from mill mill scale, from coal dust, from lime, dolomite and magnesia dust, from cast iron, aluminum and copper shavings, concentrates for the enrichment of ferrous and non-ferrous metallurgy. With a volume of 5 to 150 cm ³ , overpressure is created on the hydraulic gear press, on the edges of the teeth (curly), which will allow crushing, grinding, tearing of any materials and pressing them, as well as squeezing water and other liquids. The briquette is stronger, cheaper, because the working area is reduced several times in comparison with the roll. Mechanical ejection of briquettes is provided.

Description

The device relates to the production of fuel briquettes for domestic and industrial needs, as well as for the production of briquettes from sludge, ash and shavings for remelting.

Known devices for producing fuel briquettes, including separately mining, grinding and drying A.S. USSR No. 958467 MKI C 10 F 7/06 of 09/15/82. The known device and method is not economical enough, as well as energy-intensive due to the separate grinding and drying of the constituent briquettes.

The closest in technical essence to the claimed device is a roll press DE No. 2305626 and patent No. 2197389, but it has a number of disadvantages: dimensions, large mass, energy consumption, preliminary grinding, sieving and drying of the pressed concentrate and dosage.

The task underlying the claimed device is to create a simpler and more economical by eliminating the operation of grinding, sieving, mixing, dosing, on a large diameter hydraulic gear press.

The problem is solved as follows. Between gears with a diameter of up to 1000 mm and a width of up to 400 mm, raw lignin, sawdust, peat, wood shavings and wood chips, or any other material enters from the hopper under their weight. One of the gears is rigidly fixed in the housing to the bearings, and the other gear is hydraulically pressed against the rigidly fixed. At the ends of the gear teeth there is a conical or spherical recess. As a result of work between the teeth of the gears, briquettes will be formed from any materials, be it peat, lignin, sawdust, wood chips, pulverized and large materials from nickel, copper, aluminum, magnesium, titanium, iron, coal for use in non-ferrous and ferrous metallurgy.

Due to the fact that the rolls are replaced by gears, on the tooth faces, excessive pressure is created that will allow you to create durable briquettes from any material, while any material will be crushed, snacked and wrung out due to conical or semicircular notches on the teeth, while pressure decreases by 10 times compared with rolls.

The listed set of features allows, in comparison with the prototype, to make the inventive device simpler with reduced energy consumption and reduced cost of briquettes due to operations such as grinding, drying, sieving and dosage.

The presence of significant features distinctive from the prototype allows us to recognize the claimed device as new.

The prior art does not reveal solutions that would have features that match the distinctive features of the claimed device, so the latter meet the condition of an inventive step.

The possibility of using the claimed device in industry allows us to conclude that it meets the criterion of "industrial applicability".

The device operates as follows:

Between the gears of the press from the hopper sprinkled source material. Gears are crushed, crushed, squeezed out liquids from the material and pressed, since excess pressure is formed on the edges of the teeth, which allows you to create durable briquettes from any materials for the fuel and metallurgical industries.

Technical characteristics of the briquettes obtained by the claimed device, identified empirically. Example: gears are never used in the woodworking industry, as sawdust and shavings drive gears and break them and bearings. Briquettes are durable and second only to briquettes in plastic film No. 2001126026.

Claims (1)

A device for producing fuel and metal briquettes, including drying, grinding, sieving, dosage, characterized in that, in order to save bonding components and to further increase the strength of the briquettes, the rollers are replaced by gears, on the edges of the teeth of which excess pressure is created for the production of any sizes briquettes, depending on the gear module and the notches on the tooth crests.
