Abstract

The utility model relates to a box carbon roasting oven which contains a bed body downside and a plurality of baking units upside. The utility model is characterized in that the baking units is composed of a fire wall and an upper open product box separated with the fire wall; the two ends of the fire wall is arranged with a burning heating chamber in which a heating fire path is arranged; the heating fire path forms an unobvious fire path via orthogonal obstructs. The heating fire path communicates with the bed body smoke canal in the bed body, and communicates with a chimney through the smoke canal outlet. The box carbon roasting oven of the utility model can save energy, reduce pollution, lower the work intensity, and improve the labor environment for the workers. The rate of the qualified products is high with much product specification.

Description

Box carbon roasting furnace

Technical field

The utility model relates to the carbon industry roaster, particularly relates to a kind of box carbon roasting furnace.

Background technology

Roasting is a very important together technical process in the plain production process of charcoal, its objective is the binding agent coking that makes in the carbon product, gets rid of fugitive constituent, improves its mechanical strength, electric conductivity and hear resistance.At present, the roaster that charcoal ink factory both domestic and external man generally adopts has two kinds: i.e. circular furnace and the stove of falling the cigarette, wherein circular furnace invest huge, the unable construction of medium-sized and small enterprises; The stove of falling the cigarette is suitable for medium-sized and small enterprises investments, but its defective is outstanding, is mainly: 1) can only roasting small dimension brick fuel, and length promptly can't be gone into the stove roasting greater than 1500mm; 2) energy consumption height, loading amount is little, and the every stove loading amount of stove is fallen at the 40-45 ton in traditional three holes, and the ton product consumes bituminous coal and is about the 1.5-2 ton; 3) bitumen flue gas of the flue gas of bituminous coal and product volatilization is directly discharged by chimney, causes environmental pollution bigger; 4) its point for measuring temperature can only detect fiery temperature, and the heating curve of technological requirement is difficult to grasp control, and the product quality qualification rate is had considerable influence, even can cause whole stove to be scrapped; 5) owing to be manually to take on stove, cause work situation abominable, workman's operation intensity height, generally when roasting high temperature, every stove needs 4-6 name operation personnel at high temperature, carries out high-intensity manual labor under the high brightness state and just can finish, and the health of operating worker is had big negative effect.Of paramount importancely be, adopt simple and crude pit furnaces such as above-mentioned circular furnace and the stove of falling the cigarette, not only yield poorly, and about causing in the stove easily, the left and right sides temperature difference big (generally at 300-500 ℃), the quality of reduction product.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, but provides a kind of roasted product qualification rate height, energy savings, minimizing to pollute, reduces labor strength, improves the box carbon roasting furnace of worker laboring environment and production plurality of specifications brick fuel.

The technical solution of the utility model is achieved through the following technical solutions:

A kind of box carbon roasting furnace, several roasting unit that comprise bottom a heatable brick bed body and top thereof, it is characterized in that: described roasting unit is formed by wall with flues and by the open product box in top that wall with flues separates, described wall with flues two ends are provided with combustion heating chamber, its inside is provided with the heating quirk, constitutes no obvious quirk by orthogonal partition in the described heating quirk; A heatable brick bed body flue in above-mentioned heating quirk and a heatable brick bed body communicates, and communicates by flue outlet and with chimney;

Described flue outlet is provided with flashboard.

The advantage of the box carbon roasting furnace of the utility model is:

1. this batch-type furnace is a semi-underground type, the two ends heating, and the no obvious fire-path type wall with flues of employing in the stove, furnace gas is evenly disperseed after entering the heating quirk, make the temperature in the product box keep consistent relatively: front and back, upper and lower temperature difference about 100 ℃, thereby guaranteed the quality and the qualification rate of product;

2. this batch-type furnace adopts the open product box in top, in process of production, the bitumen flue gas condensation that product can be overflowed is among inserts, solved that the greatest contamination project in the carbon industry---bitumen flue gas is to the pollution of atmosphere, the open product box in top can realize that overhead traveling crane takes on stove simultaneously, not only improves workman's work situation greatly, reduce working strength of workers, and safety coefficient is improved greatly;

3. adopt this batch-type furnace to produce carbon brick, its ton product consumption bituminous coal amount only is the 0.6-0.7 ton, has saved the energy greatly;

4. this batch-type furnace can be according to producing needs arbitrary combination in the 3-20 case, and box height is 5 meters, but all size product of roasting length below 3800mm.

The specific embodiment

Box carbon roasting furnace of the present utility model, its main body is to be built by laying bricks or stones by refractory material to form, outside by insulating brick, common brick, fastening ironware is formed, its main body comprises several roasting unit b on bottom a heatable brick bed body a and top thereof, each roasting unit b all forms by wall with flues 3 and by the open product box 2 in top that wall with flues 3 separates, described wall with flues 3 two ends are provided with combustion heating chamber 4, its inside is provided with heating quirk 5, constitute no obvious quirk by orthogonal partition 6 in the described heating quirk 5, cutting off 6 has choked flow and prevents the effect that wall with flues is out of shape, wall with flues 3 tops also are provided with thermal insulation layer 11 and peep hole 10, to realize operate as normal; A heatable brick bed body flue 7 in above-mentioned heating quirk 5 and a heatable brick bed body a communicates, and communicates by flue outlet 8 and with chimney 1, and described flue outlet 8 is provided with flashboard 9, in order to control flue flow, makes to keep micro-vacuum state in the wall with flues.

Claims

1. box carbon roasting furnace, several roasting unit (b) that comprise bottom a heatable brick bed body (a) and top thereof, it is characterized in that: described roasting unit (b) is formed by wall with flues (3) and by the open product box in top (2) that wall with flues (3) separates, described wall with flues (3) two ends are provided with combustion heating chamber (4), its inside is provided with heating quirk (5), constitutes no obvious quirk by orthogonal partition (6) in the described heating quirk (5); A heatable brick bed body flue (7) in above-mentioned heating quirk (5) and a heatable brick bed body (a) communicates, and communicates by flue outlet (8) and with chimney (1).
