Referring to fig. 1 and 2, the present embodiment provides a combined-type high-efficiency incinerator with a furnace arch and a fire grate, which comprises a fire grate 1, a furnace chamber 2 and a furnace arch 3, wherein the furnace chamber 2 is covered on the fire grate 1, a containing cavity 4 for containing the furnace arch 3 is formed between the furnace chamber 2 and the fire grate 1, the furnace arch 3 is located above the fire grate 1, the extending direction of the furnace arch 3 is the same as the extending direction of the fire grate 1, and the furnace arch 3 is a structure protruding back to the fire grate 1. According to the combined type high-efficiency incinerator with the furnace arch 3 and the fire grate 1, through the structure that the furnace arch 3 is arranged on the back of the fire grate 1 in a protruding mode, when garbage is incinerated on the fire grate 1, the heat generated by incineration is upwards diffused and can be blocked by the furnace arch 3 to be reflected back to the fire grate 1, so that the heat on the fire grate 1 is concentrated, and the garbage incineration efficiency is accelerated.

Specifically, two ends of the fire grate 1 along the extending direction are respectively provided with a feeding end 11 and a discharging end 12, and the top surface of the fire grate 1 is provided with a garbage incineration area and a garbage moving area. The garbage falls on the top surface of the fire grate 1 from the feeding end 11 of the fire grate 1 to be incinerated and gradually moves to the discharging end 12 to be discharged.

More specifically, the feeding end of the fire grate 1 is provided with a pushing mechanism 5, the discharging end 12 of the fire grate 1 is provided with a discharging hole 13, and the discharging hole 13 penetrates through the fire grate 1 along the height direction of the fire grate 1. Therefore, after the garbage falls on the feeding end 11 on the top surface of the fire grate 1, the pushing mechanism 5 pushes the garbage to move towards the discharging end 12, burns in the moving process, and then is discharged from the discharging hole 13 of the discharging end 12 to complete the garbage burning process.

The pushing mechanism 5 of the embodiment comprises a pushing block 51 and a pushing cylinder 52, wherein a telescopic rod of the pushing cylinder 52 is fixedly connected with the pushing block 51, so that the telescopic rod of the pushing cylinder 52 stretches to push the pushing block 51 to move from the feeding end 11 to the discharging end 12, and garbage is pushed to move from the feeding end 11 to the discharging end 12.

In order to facilitate the pushing of the garbage, the height of the feeding end 11 of the fire grate 1 of the present embodiment is greater than the height of the discharging end 12 of the fire grate 1, so that along with the pushing of the pushing mechanism 5, the garbage can gradually move from the feeding end 11 to the discharging end 12, so as to accelerate the discharging of the garbage after incineration, and avoid the influence of the garbage incineration efficiency caused by accumulation on the fire grate 1.

On the basis, the top surface of the fire grate 1 is of an uneven structure arranged along the extending direction. In this embodiment, the top surface of the fire grate 1 is designed into an uneven structure, so that the moving speed of the garbage from the feeding end 11 to the discharging end 12 can be slowed down to a certain extent, and the garbage can be incinerated more thoroughly.

The uneven structure of the top surface of the grate 1 of the present embodiment may be a wavy structure, a zigzag structure, or other irregular structure, etc. disposed along the extending direction thereof, so long as the uneven requirement is satisfied, and it is not listed here.

Whereas for the feeding of waste at the feeding end 11 of the grate 1, this embodiment is realized by means of waste channels. The accommodating cavity 4 of the hearth 2 is fixedly provided with a first vertical plate 21 and a second vertical plate 22, the first vertical plate 21 and the second vertical plate 22 are arranged at the feeding end 11 of the fire grate 1 at intervals in parallel perpendicular to the fire grate 1, and the first vertical plate 21 and the second vertical plate 22 are arranged at intervals with the fire grate 1 so as to form a garbage channel between the first vertical plate 21 and the second vertical plate 22. The refuse channel is located right above the feed end 11, whereby refuse can fall right through the refuse channel to the feed end 11 of the grate 1, and then be pushed by the pushing mechanism 5 to move towards the discharge end 12 and burn during the movement.

On the basis that the garbage channel is arranged right above the feeding end 11 of the fire grate 1, the furnace arch 3 is arranged right above other parts except the feeding end 11 of the fire grate 1, so that the furnace arch 3 can block the heat upwards diffused by the furnace arch 1 to the greatest extent.

Therefore, the furnace arch 3 of the embodiment forms a structure protruding back to the fire grate 1, when the waste is burned on the fire grate 1, the burned heat is upwards diffused and can be blocked by the furnace arch 3 to be reflected back to the fire grate 1, so that the heat on the fire grate 1 is concentrated, and the waste burning efficiency is accelerated.

Specifically, one end of the first arch segment 31 far away from the second arch segment 32 is the head end, one end of the second arch segment 32 far away from the first arch segment 31 is the tail end, and the tail end of the second arch segment 32 of the embodiment is located right above the discharge end 12 of the fire grate 1, so that the furnace arch 3 can be arranged above the fire grate 1 in a largest area to block the heat diffused by the reflective fire grate 1 to the greatest extent, so that the heat on the fire grate 1 is more concentrated, and the waste incineration efficiency is further improved.

Further, the accommodating cavity 4 is fixedly provided with a third vertical plate 23, the third vertical plate 23 is perpendicular to the fire grate 1 and arranged at the discharge end 12 of the fire grate 1, and the tail end of the third vertical plate 23 is arranged near the discharge end 12 of the fire grate 1 in a butt joint manner with the third vertical plate 23. The third riser 23 further blocks the heat diffused from the fire grate 1 so that the efficiency of the garbage incineration is further improved.

And, the distance from the head end of the first arch segment 31 to the fire grate 1 is greater than the distance from the tail end of the second arch segment 32 to the fire grate 1, so that the heat blocking and reflecting capacity of the furnace arch 3 is further improved, and the garbage incineration efficiency is further improved.
