Description

Technical Field

[0001] The invention relates to the technical field of grate combustion-supporting ignition, and in particular to an ignition and combustion-supporting device for a garbage thermal cracking grate and a use method thereof. Background Art

[0002] The ignition and combustion-supporting device of the garbage pyrolysis grate is the core component to ensure the safe and efficient start-up of the garbage pyrolysis process. Fuel is supplied to the burner through the fuel supply system. The burner sprays and ignites the fuel to generate a high-temperature flame, rapidly heating the garbage to the temperature required for pyrolysis, thereby maintaining stable operation. The emission treatment system is used to reduce environmental impact, ensuring that the entire pyrolysis process is both effective and environmentally friendly.

[0003] Traditional garbage thermal cracking grates ignite fuel through burners to provide high-temperature flames, and pre-treated garbage is put into the grate. The high temperature causes the garbage to be rapidly thermally cracked to produce combustible gases and residues. In this process, the temperature in the furnace is controlled by adjusting the fuel supply and air flow to ensure that the cracking reaction proceeds stably. The generated combustible gases can be further burned to recover energy, and the residues are subjected to subsequent treatment. However, it is difficult to assist combustion in the grate during the incineration process, resulting in the inability to quickly increase the temperature in the furnace, prolonging the thermal cracking start-up time and affecting the overall processing efficiency. Insufficient combustion will result in the incomplete thermal cracking of the garbage, resulting in a large amount of incompletely burned combustible gases and smoke, increasing the difficulty and cost of subsequent treatment. At the same time, the incompletely burned combustible gases and smoke contain harmful substances, which increase the difficulty of emission treatment and thus pollute the environment. Summary of the invention

The setting of the feeding roller makes the garbage feeding smoother and less likely to be blocked in the feeding hopper, so that the garbage enters the incinerator body and is incinerated through the grate body;

[0019] S2. When the garbage enters the grate body, the combustion seat and the oxygen pump cooperate with each other to make the combustion port spray flames, so as to achieve combustion in the grate body and improve the incineration efficiency of the garbage;

[0020] S3. Pull the limit block to remove the limit of the rotating disk, use the friction block to drive the rotating knob to rotate, and the rotation of the rotating knob drives the rotating disk to rotate, so that the rotating disk drives the transmission shaft to start rotating, and the rotation of the transmission shaft drives the fuel supply port to rotate in the grate body, so that the combustion-supporting angle of the fuel supply port can be adjusted, which is convenient for the combustion-supporting of garbage in different areas;

[0022] S5. When the fuel supply port rotates, the baffle plate is driven to rotate synchronously. The baffle plate rotates so that the linkage pipe can be blocked from the fuel supply port to prevent the combustion-supporting flame from damaging the linkage pipe.

[0023] S6. The electric push rod drives the moving plate to move up and down, and the movement of the moving plate drives multiple top rods to move synchronously, and the movement of multiple top rods drives the top plate to move. The movement of the top plate causes the top plate to come into contact with the garbage, and the contact with the garbage causes the garbage to burn more fully.

[0025] 1. The present invention can achieve combustion-supporting of the garbage inside the grate through the setting of the combustion-supporting mechanism, so that the temperature inside the incinerator body can be quickly increased, the time for starting the thermal cracking can be reduced, and the overall processing efficiency can be improved. It avoids the situation that insufficient combustion-supporting will lead to incomplete thermal cracking of the garbage, resulting in a large amount of incompletely burned combustible gas and smoke, which increases the difficulty and cost of subsequent processing. At the same time, it solves the problem that the incompletely burned combustible gas and smoke in the traditional device contain harmful substances, which increases the difficulty of emission processing and thus causes pollution to the environment;

[0026] 2. Through the setting of the air supply mechanism, the present invention can achieve wind blowing at the bottom of the fuel supply port, thereby improving the combustion rate of the combustion-supporting mechanism, helping to reduce the residual unburned garbage, thereby improving the overall combustion efficiency, and can more accurately control the problems in the grate body, helping to prevent the grate body from being blocked and keeping it unobstructed. The air supply volume can be automatically adjusted according to the actual situation in the furnace, further making the operation more flexible and convenient, and reducing dependence on manual intervention.

[0027] 3.

At the same time, pushing the garbage can prevent certain components from melting and sticking to the grate body during the incineration process, thereby avoiding the coking of garbage and affecting normal operation.

[0042] Please refer to Figure 2 , Figure 3 and Figure 4, a combustion-supporting mechanism 2 is located at the top of the grate body 5 and is used to support combustion inside the grate body 5. The combustion-supporting mechanism 2 includes a fuel supply seat 21 fixed on the top of the incinerator body 1 and an oxygen pump 22 installed on the top of the fuel supply seat 21. A fuel supply pipe 23 and a connecting pipe 24 are connected to the same side of the fuel supply seat 21 and the oxygen pump 22 respectively. The fuel supply pipe 23 is communicated with the connecting pipe 24. The connecting pipe 24 extends to the interior of the grate body 5 and is installed with a sealing box 25. A fuel supply port 28 is connected to the bottom of the sealing box 25. A rotating component for driving the fuel supply port 28 to rotate is arranged between the fuel supply port 28 and the grate body 5. Two connecting soft plates 211 are connected between the sealing box 25 and the fuel supply port 28, and interference strips 29 are fixed on both sides of the bottom of the sealing box 25. The fuel supply port 28 and the interference strips 29 are mutually connected. Correspondingly, the rotating assembly includes two rotating seats 213 fixed on the top of the combustion port 28, the two rotating seats 213 are hinged to the bottom of the sealing box 25, and the two sides of the two rotating seats 213 are respectively connected with a rotating shaft 212 and a transmission shaft, the rotating shaft 212 and the transmission shaft respectively extend to the two sides of the grate body 5 and are fixed with baffles and a rotating disk 27, a limiting assembly for limiting the rotating disk 27 is arranged between the rotating disk 27 and the grate body 5, the limiting assembly includes a fixing groove opened on the top of the grate body 5 and a limiting block 210 installed inside the fixing groove, a plurality of limiting holes for inserting the limiting block 210 are opened on one side of the rotating disk 27, a control groove is opened on the top of the limiting block 210, and protrusions are fixed on both sides of the limiting block 210, and protrusions for sliding the protrusions are opened on both sides of the fixing groove;

[0043] When garbage enters the grate body 5, the combustion supply seat 21 and the oxygen pump 22 cooperate with each other, so that the combustion port 28 sprays flames into the grate body 5, thereby achieving a combustion-supporting effect, and the control groove drives the limit block 210 to move in the fixed groove, and the movement of the limit block 210 drives the convex block to move in the convex groove, so that the limit block 210 is separated from the limit hole. After the limit block 210 is separated from the limit hole, the rotating disk 27 starts to rotate through the rotating knob 26, and the rotation of the rotating disk 27 drives the transmission shaft to start rotating, and the rotation of the transmission shaft drives the rotating seat 213 to rotate, and the rotating seat 21 The rotation of 3 drives the fuel supply port 28 to rotate synchronously.

[0045] Please refer to Figure 5 , pictures and Figure 7 The top of the grate body 5 is provided with an air supply mechanism 3 for supplying air to the combustion port 28. The air supply mechanism 3 includes an air pump 33 fixed on the top of the grate body 5.

A rotating groove for the linkage pipe 32 to rotate is provided on one side of the interior of the grate body 5. A groove cavity for inserting the baffle plate 31 is provided inside the rotating groove.

[0046] The air is delivered to the air pipe 35 through the air pump 33 using the air intake pipe 34, and then delivered to the linkage pipe 32 through the air pipe 35, and then ejected through the nozzle 36, so that the fuel supply port 28 can be supported by wind during combustion, further improving the combustion efficiency. When the fuel supply port 28 rotates, it drives the baffle plate 31 to rotate synchronously.

[0054] S5, when the fuel supply port 28 drives the blocking plate 31 to rotate synchronously during the rotation process, the linkage pipe 32 can be blocked from the fuel supply port 28 by the rotation of the blocking plate 31, so as to prevent the combustion-supporting flame from damaging the linkage pipe 32;

[0055] S6. The electric push rod 42 drives the moving plate 43 to move up and down. The movement of the moving plate 43 drives the multiple top rods 44 to move synchronously.
