The disclosure relates to the technical field of crop treatment, in particular to a combustion mechanism.
A large amount of accumulated ash is generated in a combustion machine using the crops as combustion fuel, manual periodic shutdown is needed for cleaning, and the use efficiency is affected.
The disclosure aims to solve at least one of the technical problems in the prior art, and provides a combustion mechanism capable of automatically cleaning accumulated ash in equipment.
According to an aspect of the disclosure, a combustion mechanism is provided including:
a combustion chamber;
an inner container arranged in the combustion chamber, the inner container being provided with:
a feeding pipe extending into the inner container for feeding materials into the inner container;
a nozzle in the inner container for blowing air to cause accumulated ash into the ash discharge pipe, and a first suction fan being arranged in the ash discharge pipe;
a gas driving mechanism connected with the nozzle for outputting jet gas to the nozzle; and
an air supply mechanism outside the combustion chamber for supplying air to the inner container and the gas driving mechanism.
Advantageous effects: the air is driven into the inner container by the gas driving mechanism, so that the ash accumulated on the inner wall of the inner container falls off and is discharged out of the combustion chamber along the ash discharge pipe under the suction of the first suction fan.
In some embodiments, the air supply mechanism includes a second suction fan, and an air duct with one end communicated with the second suction fan and the other end extending into the inner container. The second suction fan draws air from the outside of the combustion chamber and provides oxygen for a second igniter of the inner container, and meanwhile. Furthermore, a portion of the air enters the gas driving mechanism to supply raw materials to the gas driving mechanism.
In some embodiments, the air supply mechanism includes several air ducts respectively with a solenoid valve. The amount of oxygen entering the inner container is controlled by opening or closing the solenoid valve so as to control the combustion fire intensity.
In some embodiments, the gas driving mechanism includes an air intake pipe, an acetylene intake pipe, a gas mixer, a second igniter and a pulse generator, the nozzle is mounted to the pulse generator, the air intake pipe and the acetylene intake pipe are respectively communicated with the gas mixer, the gas mixer is communicated with the second igniter, the second igniter is communicated with the pulse generator, and at least one of the air ducts is communicated with the air intake pipe. The acetylene and air are mixed by the gas mixer to form combustible gas, which enters the pulse generator after being ignited to form a strong-wave jet gas flow, and ash accumulated on the inner wall of the inner container is strongly vibrated and falls off.
In some embodiments, several pulse generators and several nozzles are provided. Several nozzles simultaneously jet gas flow to the ash on the inner container, so that the impact force is improved, and the ash sufficiently falls off.
In some embodiments, a heated net surface which abuts against the inner container is arranged in the combustion chamber, the inner container is provided with an ash discharge opening, an inclined guide groove is arranged below the heated net surface, the inclined guide groove is arranged below the ash discharge opening, an ash collection area with an opening and closing gate is arranged below the ash discharge opening. The remaining ash falls into the ash collection area along the guide rail, and the ash discharge opening is opened for treatment after production is finished.

Referring to
a combustion chamber 10; it should be mentioned that the combustion chamber 10 is capable of isolating the outside from the inside, preventing accidents from occurring;
an inner container 20 arranged in the combustion chamber 10, the inner container 20 is internally provided with a first igniter 21, the inner container 20 is provided with a fire outlet pipe 22 extending from the inner cavity of the inner container 20 to the outside of the combustion chamber 10, the inner container 20 is provided with an ash discharge pipe 23 arranged above the inner container 20 and extending to the outside of the combustion chamber 10;
a feeding pipe 30 extending into the inner container 20 and feeding materials into the inner container 20;
a nozzle 60 arranged in the inner container 20 and blowing air to cause accumulated ash into the ash discharge pipe 23, a first suction fan 231 is arranged in the ash discharge pipe 23;
a gas driving mechanism 40 connected with the nozzle 60 and outputting jet gas to the nozzle 60;
an air supply mechanism 50 arranged outside the combustion chamber 10 for supplying air to the inner container 20 and the gas driving mechanism 40.
In use, air is jetted into the inner container 20 via the nozzle 60 by the gas driving mechanism 40, so that ash accumulated on the inner wall of the inner container 20 falls off, and the ash is discharged out of the combustion chamber 10 along the ash discharge pipe 23 under the suction of the first suction fan 231.
In some embodiments, the air supply mechanism 50 includes a second suction fan 51 and an air duct 52, one end of the air duct 52 is communicated with the second suction fan 51, and the other end of the air duct 52 extends into the inner container 20. The second suction fan 51 draws air from outside of the combustion chamber 10 and provides oxygen for a second igniter 44 of the inner container 20. Furthermore, a portion of the air enters the gas driving mechanism 40 to supply raw materials to the gas driving mechanism 40.
In some embodiments, there are several air ducts 52 each with a solenoid valve 521. The amount of oxygen entering the inner container 20 is controlled by opening or closing the solenoid valve 521 so as to control the combustion fire intensity.
In some embodiments, referring to
