Abstract

The utility model relates to a 19-hole lattice brick which effectively solves the problems of small unit heating area and heat storage volume, low through hole rate, poor heat transfer effect and waste of refractory materials. Vertically communicated vent holes are evenly distributed in a brick body, gas gathering grooves communicated with four peripheral vent holes are respectively evenly distributed on the upper surface of the brick body, the vent holes arranged on an outer circle of the upper surface of the brick body are mutually communicated to form a hexagonal groove, projections with the sizes matched with those of the gas gathering grooves are arranged on the lower surface of the brick body, the projections and the gas gathering grooves are positioned on the same central line, and a central groove communicated with the central vent hole and seven peripheral vent holes is arranged at the center of the lower surface of the brick body and is connected with the inner sides of the projections. The 19-hole lattice brick is simple in structure and fine in heat transfer effect, the unit heating area and the heat storage volume are increased, refractory material consumption of an air heating furnace is greatly reduced, and investment of the air heating furnace is reduced.

Description

A kind of 19 hole checker brick

Technical field

The utility model relates to refractory brick, particularly a kind of 19 hole checker brick.

Background technology

19 hole checker brick are in hotblast stove, to use more a kind of heat storage at present, but because the problem that exists on the structure, unit heating-surface area and accumulation of heat volume are less than normal; It is stifled that the top layer is prone to ash, and through-hole rate is low, and heat-transfer effect is poor; Use not fully up to expectations; And waste anti-material, increased considerably the investment of hotblast stove, thus improve and innovate imperative.

Summary of the invention

To above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of 19 hole checker brick, and effectively the unit's of solution heating-surface area and accumulation of heat volume are little, and through-hole rate is low, and heat-transfer effect is poor, wastes the problem of anti-material.

The technical scheme that the utility model solves is; Comprise brick body, ventilating pit, gather qi together groove and convex body; Be evenly equipped with the ventilating pit of upper and lower connection in the brick body; Be evenly equipped with respectively above the brick body and four gather qi together grooves that ventilating pit is connected of periphery, place the ventilating pit of outer ring above the brick body formation hexagonal indentations that is interconnected, have and the gather qi together groove convex body that size matches on same medullary ray below the brick body; Below the brick body there be and center and 7 central recess that ventilating pit is connected of periphery the center, the inboard of central recess and convex body is connected.

The utility model is simple in structure, has increased unit heating-surface area and accumulation of heat volume, and heat-transfer effect is good, has reduced the anti-material use quantity of hotblast stove significantly, has reduced the hotblast stove investment.

Fig. 2 is that the A-A of the utility model Fig. 1 is to the structure sectional view.

Embodiment

Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.

Provide by Fig. 1-Fig. 2; The utility model comprises brick body, ventilating pit, gather qi together groove and convex body; Be evenly equipped with the ventilating pit 2 of upper and lower connection in the brick body 1; Be evenly equipped with respectively above the brick body and four gather qi together grooves 4 that ventilating pit is connected of periphery, place the ventilating pit of outer ring above the brick body to be interconnected to constitute hexagonal indentations 5, have and the gather qi together groove convex body 6 that size matches on same medullary ray below the brick body; Below the brick body there be and center and 7 central recess 3 that ventilating pit is connected of periphery the center, the inboard of central recess and convex body is connected.

Described ventilating pit 2 is up-small and down-big taper; Described gather qi together groove 4 is that mouthful inclined-plane that the big end is little is circular with central recess 3, and the gather qi together groove has 3, is distributed on the brick body.

When the utility model used, the convex body of top checker brick placed in the corresponding gather qi together groove of following checker brick in per two adjacent checker brick, prevents that the dislocation of brick body from moving; And the increase of hexagonal indentations, the unit's of making heating-surface area and accumulation of heat volume increase, and are interconnected between the Kong Yukong; Through-hole rate is high, and heat-transfer effect is good, avoids the accumulation and the bonding of dust; Make the heat exchange amount of hotblast stove reach mxm., be beneficial to heat absorption and heat release.
