[0001] This utility model relates to the field of waste incinerator technology, specifically a burner for a waste incinerator. Background Technology

[0002] Waste incinerators are important environmental protection equipment designed to effectively treat various types of waste through high-temperature incineration technology. Through the high-temperature incineration process, waste incinerators fully burn the combustible components in the waste, thereby greatly reducing the volume and weight of the waste. The burner of the waste incinerator is the core equipment used to provide a high-temperature combustion environment.

[0003] In actual use, the combustion gases in the burner need to come into contact with air to achieve complete combustion. If the amount of air in contact is too small, the air and combustion gases will not mix sufficiently, resulting in incomplete combustion of natural gas and affecting the burner's incineration effect on waste.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, a burner for a waste incinerator includes a burner body 1. An igniter 2 is fixedly connected inside the burner body 1. A nozzle 3 is fixedly connected to one side of the igniter 2. A gas pipe 4 connected to the burner body 1 is fixedly connected to the upper side of the burner body 1. Natural gas can be supplied through the gas pipe 4. The nozzle 3 is remotely powered. The burner is a combustion device that mainly uses oil fuel or natural gas. When the igniter 2 is working, it generates a high-voltage electric spark. The electric spark directly ignites the fuel sprayed from the nozzle 3 to form a stable initial flame. This is existing technology, and its specific model is not limited. A connecting block 6 connected to the burner body 1 is fixedly connected to one side of the burner body 1. A cylinder 7 is fixedly connected to one side of the connecting block 6. A piston 9 is slidably connected inside the cylinder 7. A telescopic rod 10 is fixedly connected to one side of the piston 9.

[0025] One side of the telescopic rod 10 passes through the cylinder 7 and extends to the other side of the cylinder 7. An L-shaped frame 11 is fixedly connected to one side of the telescopic rod 10. An arc-shaped through groove 12 is opened on the L-shaped frame 11. A side plate 5 is fixedly connected to one side of the burner body 1. A rotating shaft 13 is rotatably connected to the lower side of the side plate 5 through a servo motor. The servo motor is model SMBL-60P. A cam 14 is fixedly connected to the lower side of the rotating shaft 13. A toggle rod 15 is fixedly connected to the lower side of the cam 14. The design of the cam 14 allows the toggle rod 15 to slide back and forth in the arc-shaped through groove 12 on the L-shaped frame 11, ultimately driving the L-shaped frame 11 to produce regular oscillation. When the piston 9 moves into the cylinder 7, a negative pressure is formed in the cylinder 7, drawing in air from the external environment through the air inlet, accelerating the air flow, and improving the combustion effect.

[0026] The lower side of the lever 15 is slidably placed inside the arc-shaped through groove 12, and the output shaft of the servo motor is fastened to the rotating shaft 13.

[0027] A fixing plate 22 is fixedly connected inside the burner body 1. A guide rod 18 is slidably connected to the upper side of the fixing plate 22. A sealing element 20 is fixedly connected to the upper side of the guide rod 18. The sealing element 20 is located below the gas pipe 4. A first spring 21 is fixedly connected between the sealing element 20 and the fixing plate 22.

[0028] An air inlet is provided on the cylinder 7, and a one-way valve is installed inside the air inlet. The one-way valve allows external gas to enter the cylinder 7 in one direction.

[0029] The lower side of the guide rod 18 passes through the fixed plate 22 and extends to the lower side of the fixed plate 22. The lower side of the guide rod 18 is fixedly connected to the driven cone block 19. The other side of the piston 9 is fixedly connected to the connecting plate 16. The one side of the connecting plate 16 is fixedly connected to the active cone block 17 that abuts against the driven cone block 19. The connecting block 6 has a through hole, and a sealing gasket is fixedly installed in the through hole. The connecting plate 16 passes through the through hole and is slidably sealed. The connecting block 6 has an air outlet, and a one-way valve is installed in the air outlet to allow the gas in the cylinder 7 to enter the burner body 1.

[0030] A spiral water pipe 8 is fixedly connected to the outer surface of the burner body 1. A water outlet pipe 23 connected to the spiral water pipe 8 is fixedly connected to the lower side of the spiral water pipe 8. A water inlet pipe 24 connected to the spiral water pipe 8 is fixedly connected to the upper side of the spiral water pipe 8. The spiral water pipe 8 adopts a circumferential multi-layer spiral structure, which can surround the burner with the maximum contact area, thereby efficiently removing the heat generated by the burner during continuous operation.

[0031] The working principle of the burner in the waste incinerator provided by this utility model is as follows:

[0032] By manually opening the valve on the gas pipe 4, natural gas is allowed to enter the burner through the gas pipe 4. Then, the servo motor is turned on. At this time, the output shaft of the servo motor can drive the cam 14 below the rotating shaft 13 to rotate. This allows the lever 15 to slide in the arc-shaped through groove 12 of the L-shaped frame 11, so that the L-shaped frame 11 can drive the piston 9 on one side of the telescopic rod 10 to extend and retract back and forth in the cylinder 7. When the piston 9 is compressed, it can transmit the external gas to the burner body 1. According to the combustion requirements, the controller can control the servo motor to turn on intermittently, so as to intermittently accelerate the air flow and quickly inject it into the burner, increasing the oxygen supply. Then, the oxygen in the air and the natural gas can be fully mixed to achieve full combustion of natural gas, improving the burner's incineration effect and efficiency of waste.

[0033] By using a water pump, cold water can be injected into the spiral water pipe 8 through the inlet pipe 24. The spiral water pipe 8, filled with cold water, carries away the heat generated by the burner in a circular manner and is then discharged through the outlet pipe 23, thus achieving a circulating heat dissipation effect. At the same time, the hot water can be left to cool and reused. Then, when the combustion stops, the controller can control the start and stop of the servo motor, so that the toggle lever 15 below the cam 14 stops in the middle position of the arc-shaped through groove 12. At this time, the piston 9 is in a compressed state, causing the active cone block 17 to press against the driven cone block 19, causing the elastic seal 20 to move upward to seal the gas pipe 4, so as to automatically cut off the natural gas supply and provide safety for subsequent operations. After the automatic cut-off is completed, the operator can manually close the valve installed on the gas pipe 4 to ensure the complete shutdown of the gas supply system and eliminate the risk of natural gas leakage.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
