Abstract

The utility model discloses a bottom cooling structure of a carbon can-type furnace. A ninth layer flame path is additionally arranged below an eighth layer flame path, and air path bricks of a cooling wind path are placed in the newly arranged flame path. A silica brick layer is downward extended to the plane of a brick layer of a bottom-layer air path. High-strength heat insulating bricks are additionally arranged between fire bricks at the bottom of the furnace and a plate at the bottom of the furnace. Hollow bricks of the cooling wind path of the utility model do not bearing weight, and have long service life, good cooling effect of the bottom of the furnace and good calcining quality. Therefore, the production of specially shaped bricks is reduced and the expenses for investment can be saved.

Description

Pot type burner bottom cooling structure

Technical field:

The utility model relates to the refractory material masonry construction of the plain can-type calcine furnace of charcoal bottom.

Background technology:

The plain can-type calcine furnace bottom construction of used in the past charcoal is: be in below the silica brick at the 8th layer of quirk place, generally adopt schamotte brick to build by laying bricks or stones, be furnished with the cooling air channel hollow brick in the brick layer and come at the bottom of the cool furnace.But because the cooling capacity of this structure is not enough, sealing between the flange of drop-bottom and the cooling jacket adpting flange is owing to the high temperature deformation of flange destroys, cause the calcining material in this place's batch can " to leak material and leak fire " outward, both influenced the stove ordinary production, have potential safety hazard again.In addition, the direct bearing load of cooling air channel hollow brick in this structure all has negative influence to its manufacturing, construction and life-span.

Summary of the invention:

The purpose of this utility model is: under the prerequisite that guarantees burning quality, provide a kind of and both can guarantee that the furnace bottom cooling was good, have better cooling air channel bearing mode again, simultaneously economical and practical pot type burner bottom cooling structure is to overcome the deficiencies in the prior art part.

The utility model is to constitute like this: it comprises the 8th layer of quirk (1) of the plain can-type calcine furnace of charcoal and is located at batch can (9) between the silica brick layer (5), under the 8th layer of quirk (1), set up the 9th layer of quirk (2), silica brick layer (5) extends downward bottom air channel brick layer plane, place primary air road brick (3) and auxiliary air road brick (4) at interval in the 9th layer of quirk (2), all the other spaces are filled out with the refractory brick grain; Between furnace bottom refractory brick (6) and drop-bottom (8), high-strength heat preservation brick (7) is set.

Owing to adopted technique scheme, the utility model adopts the quirk frame mode to strengthen the furnace bottom cooling effect; And owing to set up furnace bottom high-strength heat preservation brick, thereby strengthened the effect of heat insulation of furnace bottom.

The utility model compared with prior art has following advantage: 1, primary air road brick (3) and not load-bearing of auxiliary air road brick (4), and make design, the manufacturing of this brick and construct more conveniently, prolong service life; 2, owing to interlayer material silica brick layer between cooling air and the calcining material is thinner, thermal conduction resistance is littler, and air preheating temperature improves, and the furnace bottom cooling effect is better; 3, the thickening of whole bottom brick layer, prolonged stove from the 8th layer of quirk (1) space to continuous temperature landing drop-bottom, make the 8th layer of quirk (1) and above stove burning zone thereof not influenced, be equivalent to the burning zone that extended, more help burning quality because of the reinforcement of furnace bottom cooling; 4, because silica brick layer (5) moves down the so also related batch can that extended (9); Moreover new stove still adopts the existing silica brick that batch can is used of building by laying bricks or stones at these positions, avoided the preparation of the about 10 kinds of special shaped bricks of clay matter of general pot type burner, has saved investment cost.

In sum, the beneficial effects of the utility model are: the not load-bearing of cooling air channel hollow brick, and long service life, furnace bottom cooling and good heat-insulation effect, burning quality improves, and has reduced the preparation of special shaped brick, has saved investment cost.

Description of drawings:

Fig. 1 is a schematic diagram of the present utility model.

Among the figure, 1. the 8th layer of quirk, 2. the 9th layer of quirk, 3. primary air road brick, 4. auxiliary air road brick, 5. silica brick layer, 6. furnace bottom refractory brick, 7. high-strength heat preservation brick, 8. drop-bottom, 9. batch can.

The specific embodiment:

Embodiment of the present utility model: divide into the 9th layer of quirk 2 at the 8th layer of quirk 1, and silica brick layer 5 is extended downward bottom air channel brick layer plane, so also related the lengthening is located at batch can 9 between the silica brick layer 5; Place primary air road brick 3 and auxiliary air road brick 4 at interval in the 9th layer of quirk 2, all the other spaces are filled out with the refractory brick grain; Between furnace bottom refractory brick 6 and drop-bottom 8, build one deck high-strength heat preservation brick 7 by laying bricks or stones.

Claims

1. pot type burner bottom cooling structure, it comprises the 8th layer of quirk (1) of can-type calcine furnace and is located at batch can (9) between the silica brick layer (5), it is characterized in that: under the 8th layer of quirk (1), have additional the 9th layer of quirk (2), its silica brick layer (5) extends downward bottom air channel brick layer plane, is placed with primary air road brick (3) and auxiliary air road brick (4) in the 9th layer of quirk (2) at interval; Between furnace bottom refractory brick (6) and drop-bottom (8), be provided with high-strength heat preservation brick (7).
