Description

Technical Field

[0001] The present application belongs to the technical field of outdoor combustion fire grate equipment, and specifically relates to an environmentally friendly combustion fire grate device that automatically adjusts oxygen supply. Background Art

[0002] A combustion grate is a device used to regulate and control the oxygen supply during the combustion process. It is usually installed in the combustion area of ​​combustion equipment (such as coal-fired boilers, gas furnaces, etc.) to regulate the supply of air (including oxygen) to maintain the stability and efficiency of combustion.

[0003] For example, the patent with announcement number CN213686816U discloses an environmentally friendly combustion fire grate device with automatic oxygen supply adjustment, including a fire grate fixing frame, a plurality of rows of combustion fire grates, combustion fire distribution holes, and gas injection holes. The plurality of rows of combustion fire grates are fixed on the fire grate fixing frame, and the plurality of rows of combustion fire grates form a fire grate group. Longitudinally arranged oxygen supply spacing grooves are provided between the fire grates. The circumferential outer wall of the fire grate group is fixedly surrounded by a circle of enclosure frame, and the bottom of the enclosure frame is sealed with a bottom shell, and ventilation holes are provided on the bottom shell. An electric air volume regulating valve is fixed on the ventilation hole, and air can only enter from the ventilation hole. The electric air volume regulating valve is used to adjust the opening ratio of the ventilation hole, thereby adjusting the combustion oxygen supply ratio, so as to achieve the best gas and air mixing ratio for combustion.

[0004] However, when the environmentally friendly combustion grate device that automatically adjusts oxygen supply performs segmented combustion on the grate, it is difficult to control the oxygen supply ratio, resulting in poor combustion effect. Utility Model Content

[0005] The purpose of the present application is to provide an environmentally friendly combustion fire grate device with automatic oxygen supply adjustment to solve the problem that it is difficult to control the oxygen supply ratio when the fire grate is subjected to segmented combustion control, resulting in poor combustion effect.

[0006] The technical solution adopted in the present application is as follows: an environmentally friendly combustion fire grate device with automatic oxygen supply adjustment, comprising a combustion box, a combustion fire grate fixedly installed inside the combustion box, a trapezoidal air cavity fixedly connected to the bottom end of the combustion fire grate, a diverter pipe fixedly connected to the bottom of the left end of the trapezoidal air cavity, a baffle slidably connected to the side end of the trapezoidal air cavity and located at the upper end of the diverter pipe, a multifunctional pipe fixedly connected to the left end of the combustion box, a fan fixedly installed on the left end of the multifunctional pipe, and a trapezoidal air cavity fixedly connected to the right end of the multifunctional pipe and located above the diverter pipe.

[0007] By adopting the above technical solution, the interior of the combustion box is used to install the combustion grate to increase the combustion space. The trapezoidal air cavity connected to the bottom of the combustion grate is used to mix the input combustion gas and oxygen. The trapezoidal air cavity is wide on the left and narrow on the right. The multifunctional tube connected to the left end is used to provide oxygen airflow, and the shunt pipe connected to the bottom of the left end is used to provide combustion gas. The right end of the trapezoidal air cavity is a slope surface, and its rightmost end is at the smallest spatial distance from the lower end of the combustion grate. When the combustion gas is injected into the shunt pipe, the gas can be quickly ignited in sections through the air outlet at the left end of the combustion grate. The sectioned combustion can conveniently control the temperature and can be preheated. When it is necessary to increase the firepower, the fan can be started to inject oxygen into the inside of the multifunctional tube. The airflow entering at the multifunctional tube will push the gas in the trapezoidal air cavity to the right. The distance between the right end of the trapezoidal air cavity and the combustion grate is gradually shortened, and the remaining combustion grate can be quickly ignited, which is convenient for oxygen control of the combustion grate of sectioned combustion. After outdoor use, dust may accumulate inside the burning fire grate. The sliding baffle can be used to prevent the dust from entering the diversion pipe to avoid affecting the next gas supply and combustion. At the same time, the multi-functional tube can be used to extract the dust in the trapezoidal air cavity.

[0008] In a preferred embodiment, an exhaust pipe is fixedly connected to the side end of the combustion box and located above the combustion fire grate.

[0009] By adopting the above technical solution, the smoke from combustion can be discharged at the exhaust pipe.

[0011] By adopting the above technical solution, the connecting plate installed at the right end of the combustion box is used to fix the position of the air intake pipe, which is convenient for installation and removal. The air intake pipe is used to transport combustion gas.

[0012] In a preferred embodiment, a gas valve is fixedly installed at the bottom end of the air intake pipe, a gas pipe is fixedly connected to the side end of the air intake pipe, and a mounting flange is fixedly installed at the front end of the gas pipe.

[0013] By adopting the above technical solution, the mounting flange is used to install the gas supply device, which is connected to the gas pipe. The combustion gas enters the interior of the air intake pipe through the gas pipe. The entry of the gas can be controlled by the gas valve. The gas in the air intake pipe can be diverted through the diversion pipe and enter the interior of multiple combustion fire grates.

[0014] In a preferred embodiment, a rubber stopper is fixedly mounted on the left end of the baffle.

[0015] By adopting the above technical solution, when combustion is required, the baffle can be slid to the right end, and the right end of the trapezoidal air cavity can be blocked by the rubber plug.

[0016] In a preferred embodiment, an electric telescopic rod is fixedly mounted on the rear end of the baffle, and a controller is fixedly mounted on the surface of the combustion box and on one side close to the electric telescopic rod.

[0017] By adopting the above technical solution, when the inside of the trapezoidal air cavity needs to be cleaned, the controller can be used to control the electric telescopic rod to drive the baffle to slide leftward, thereby blocking the shunt pipe to prevent dust from entering the inside of the shunt pipe.

[0018] In a preferred embodiment, a guide pin is fixedly installed at the side end of the combustion box and located above the combustion fire row, and an igniter is fixedly installed at the side end of the guide pin and located outside the combustion box.

[0019] By adopting the above technical solution, the starting igniter can ignite the gas at the combustion fire grate through the guide needle.

[0020] In a preferred embodiment, a fixing plate is fixedly mounted on the top side of the combustion box.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In the present application, when the combustion gas is injected into the interior of the shunt pipe, the gas can be quickly ignited in sections through the air outlet at the left end of the combustion grate. The sectioned combustion can conveniently control the temperature and can be preheated. When it is necessary to increase the firepower, the fan can be started to inject oxygen into the interior of the multifunctional pipe.
