Abstract

The utility model relates to long round hole rectangular moulded coal, which comprises a rectangular moulded coal main body. The utility model is characterized in that a plurality of long round breather holes and a plurality of peripheral breather holes are longitudinally arranged on the moulded coal main body. A plurality of transverse breather holes are respectively arranged at the top part and the bottom part of the moulded coal main body. The moulded coal adopting the structure has the advantages that the oxygen supply capability is stronger, and the coal-burning combustion is more sufficient.

Description

Slotted hole rectangle moulded coal

Technical field

The utility model relates to the moulded coal structure, is meant a kind of rectangle type coal shape and structure especially.

Background technology

The present moulded coal that uses of enterprise all adopts the round vent supply moulded coal needed oxygen that burns.In actual use, make the oxygen supply deficiency owing to ventilation opening gets clogged, influence the moulded coal efficiency of combustion, make moulded coal can not obtain abundant burning, cause the wasting of resources through regular meeting; And prolonged combustion time of moulded coal, reduced the working efficiency of coal stove.

In order to improve moulded coal oxygen supply ability, can adopt the method that enlarges the ventilating pit diameter, still, this method must reduce the structural strength of moulded coal, moulded coal is ruptured because of external force in handling process easily, and perhaps the internal stress that produces owing to burning is split.In addition, because existing moulded coal has adopted round vent, caused between the ventilating pit of moulded coal inevitably and the rib uneven thickness between ventilating pit and the moulded coal sidewall, cause the innermost fire coal of moulded coal wall thickness to be difficult to be fully used, the method that enlarges the ventilating pit diameter can not address the above problem.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: a kind of slotted hole rectangle moulded coal is provided, under the prerequisite that guarantees the moulded coal structural strength, improves ventilation, the oxygen delivery capacity of moulded coal.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of slotted hole rectangle moulded coal comprises orthogonal moulded coal body, is arranged with several ventilating pits longitudinally on the described moulded coal body, and it is characterized in that: the cross section of described ventilating pit is Long Circle.

Wherein: described moulded coal body is provided with several peripheral vents longitudinally.

Wherein: the top of described moulded coal body and bottom are equipped with several horizontal communication holes.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

1. the utility model is bigger than existing circular hole moulded coal ventilating pit sectional area, coal when burning the ventilating pit oxygen delivery capacity strong, be difficult for blockedly, and coal can fully be burnt.

2, the utility model has increased periphery and transversal ventilation hole than existing moulded coal, makes ventilation more even, and complete, on fire fast, the grate that burns connects.

3, the utility model has increased the contact area of air and coal than existing moulded coal, makes the coal can rapid combustion, reduces combustion time, and unit time self-energy output rating is big.

4, the utility model reduces the molded coal boiler volume, saves cost, and furnace volume is reduced, and reduces the manufacturing cost of boiler and the floor space of boiler.

5, the utlity model has colleges and universities, environmental protection, energy-conservation characteristics.Making boiler enter atmospheric pollution reduces.The boiler environmental-protecting performance improves.

Description of reference numerals: 10-moulded coal body; The oblong ventilating pit of 11-; The 12-peripheral vent; 13-horizontal communication hole.

Embodiment

As Fig. 1～shown in Figure 3, be vertical view, front view and the left view of a preferred embodiment of the utility model, because in the present embodiment, the upward view of moulded coal and vertical view symmetry, rear view and front view symmetry, so right side view and left view figure symmetry is clear shape and the structure of having represented present embodiment of Fig. 1～Fig. 3, in order to represent structure of the present utility model more intuitively, can be referring to the sectional view of three different visual angles directions of Fig. 4～Fig. 6.

Can be clear that from Fig. 1, Fig. 5 the utility model slotted hole rectangle moulded coal comprises an orthogonal moulded coal body 10, be arranged with several oblong longitudinally ventilating pits 11 and several peripheral vent 12 longitudinally on the moulded coal body 10.Two adjacent row's ventilating

pits

11,12 can adopt mode side by side to arrange, and also can adopt staggered mode to arrange.Adopt said structure, oblong ventilating pit 11 is big than the round vent draught area of same diameter.And several moulded coals stack when burning, and described peripheral vent 12 can be assisted the draught capacity that improves moulded coal, and the structural strength of moulded coal 10 also is guaranteed.Said structure makes that more the rib thickness between the ventilating

pit

11,12 is even, and the coal-fired all burnt simultaneously in the moulded coal 10 is saved combustion time, improves efficiency of combustion.

Can be clear that from Fig. 2, Fig. 4 moulded coal body 10 tops and bottom are provided with several semicircular horizontal communication holes 13.When the oblong longitudinally ventilating pit 11 of moulded coal took place to block, horizontal communication hole 13 can provide the inside of oxygen to moulded coal, guarantees the abundant burning of moulded coal.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence (for example changing the arrangement mode of oval ventilating pit), but but all will fall within the claim restricted portion of the present utility model.
