Abstract
The utility model provides a concave non-round hole shaped-coal which is a column body, at least one circle of convex ring is arranged on the top face of the column body, the concave center of the column body is provided with a round through hole, and non-round through holes are regularly arranged around the round through hole. After a boiler is added with the concave non-round hole shaped-coal, the concave non-round hole shaped-coal can be burnt without being opposite to the holes, and when the concave non-round hole shaped-coal is burnt, the utility model has good ventilation, intensive burning, high heat efficiency, good strength and good processing performance.
Description
The utility model relates to a kind of burning moulded coal, particularly relates to a kind of concave surface non-circular hole moulded coal.
Existing civil honeycomb briquette is cylindrical, has on it to be the some through holes that are arranged in parallel, and from flue down coal suitable for reading, and the hole of moulded coal must be aimed at up and down during use, otherwise can not trouble-free burning.This moulded coal is unsuitable for from the cooking stove of the horizontal coal in flue side, or from the make progress cooking stove of vertical coal of flue end opening.Chinese patent 86210352 has been introduced a kind of briquette, and for cylindrical, there is manhole at the center, is that a conic shaped is arranged on arc-shaped through-hole, the briquette around the central through hole, and pit height accounts for 1/8～1/5 of briquette height.This briquette has solved not to the hole combustion problem, but the pyramidal pits edge is frangible, is difficult to processing, transportation inconvenience.
The purpose of this utility model is to provide a kind of burning strong, is particularly suitable for the concave surface non-circular hole moulded coal of counter-burning type cooking stove.
The utility model concave surface non-circular hole moulded coal is a right cylinder, has a circle bulge loop on the end face at least, in its concave surface central authorities one manhole is arranged, and is arranged with non-circular through hole all around regularly, as bar hole, trapezoidal hole, scallop hole or slotted eye etc.The cross section of bulge loop is trapezoidal, and following greater than the top.This structure moulded coal can be an one-piece construction, and also vertical molectron promptly partly is made up of several symmetries.The concave surface of moulded coal end face in flue with adjacent on a moulded coal bottom surface formed internal combustion chamber and circulation air chamber, both accumulated the inflammable gas of high heat, overheavy firing is communicated with again between adjacent moulded coal not to the ventilation channel between the through hole in hole.
The advantage of the utility model concave surface non-circular hole moulded coal is that intensity is good, and not fragile in transportation and the use, coal does not need the hole, ventilate during burning, the thermo-efficiency height, good processability, be suitable for the cooking stove of horizontal coal and from the bottom to the counter-burning type cooking stove of upper coal feeding.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Embodiment 1:
The utility model concave surface non-circular hole moulded coal is a right cylinder, and a circle bulge loop 1 is arranged on the end face, and there is manhole 3 in concave surface 2 central authorities, are arranged with arc-shaped through-hole 4 on every side regularly.
Embodiment 2:
The utility model concave surface non-circular hole moulded coal is a right cylinder, and combining by 5,6,7,8 four has two circle bulge loops 1 on the end face, and there is manhole 3 in concave surface 2 central authorities, are arranged with special-shaped through hole 4 all around regularly.
Claims (3)
1, a kind of concave surface non-circular hole moulded coal is right cylinder, and through hole is arranged on the circular section, it is characterized in that having at least on the end face circle bulge loop, in its concave surface central authorities one manhole is arranged, and is arranged with non-circular through hole all around regularly.
2, concave surface non-circular hole moulded coal as claimed in claim 1, the cross section that it is characterized in that bulge loop is trapezoidal, and is following greater than the top.
