[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 This utility model provides an embodiment of an automatic slag-discharging burner with a water-cooled grate and furnace body, comprising a base 18, a burner body 1 fixedly connected to the upper side of the base 18, a feed inlet 14 fixedly connected to the upper side of the burner body 1, a furnace body 2 fixedly installed on the right side of the burner body 1, a shell 4 fixedly connected to the outer wall of the furnace body 2, a heat-conducting plate 3 disposed inside the shell 4, the heat-conducting plate 3 being in contact with the outer side of the burner body 1, a cold water pipe 5 fixedly connected to the right side of the heat-conducting plate 3, and a water inlet pipe 15 and a water outlet pipe 16 disposed on the right side of the shell 4, both of which are connected to the cold water pipe 5. A blower 6 is fixedly installed on the upper side of the burner body 2. The right side of the blower 6 is connected to the upper side of the furnace body 2. A filter box 7 is fixedly connected to the left side of the blower 6. A sealing plate 10 is provided on the front side of the filter box 7. An installation groove 11 is opened inside the filter box 7. A filter screen 8 and an activated carbon screen 9 are fixedly installed on the rear side of the sealing plate 10. The filter screen 8 is located on the left side of the activated carbon screen 9. The filter screen 8 and the activated carbon screen 9 are slidably connected inside the installation groove 11. A grate conveyor 12 is fixedly installed inside the burner body 1. A controller 17 is fixedly connected to the front side of the burner body 1. The controller 17 is electrically connected to the blower 6 and the grate conveyor 12.

[0028] Specifically, fuel enters the burner body 1 through the feed inlet 14 and is laid on the grate conveyor 12. As the grate conveyor 12 operates, part of the heat generated by combustion is used to heat the medium inside the furnace body 2, and the other part is conducted through the outside of the burner body 1 to the heat-conducting plate 3 attached to it. After absorbing heat, the heat-conducting plate 3 transfers it to the cold water pipe 5 on its right side. The cold water pipe 5 introduces cold water through the water inlet pipe 15. After absorbing heat while flowing in the pipe, the cold water is discharged through the water outlet pipe 16, forming a circulating cooling process. This process effectively cools and reduces the temperature of the burner body 1, preventing damage to the equipment due to high temperature. At the same time, it recovers and utilizes heat, improving energy efficiency. After the controller 17 starts the fan 6... Fan 6 draws in outside air, which first enters filter box 7. Inside filter box 7, filter screen 8 on the left side intercepts large particulate impurities in the air, while activated carbon screen 9 on the right side further adsorbs odors and fine particles, purifying the air. The purified air enters from the left side of fan 6 and is then transported to furnace body 2 from the right side, providing sufficient oxygen for fuel combustion. The flue gas produced by combustion also mixes with the air inside furnace body 2, promoting a more complete combustion reaction. Through this process, the purification and precise supply of air required for combustion are achieved, improving combustion efficiency and reducing pollutants produced by incomplete combustion.

[0029] Reference Figures 4-6A cleaning and collection assembly 13 is provided on the lower side of the grate conveyor 12. The cleaning and collection assembly 13 includes a horizontal plate 131, which is fixedly connected to the inside of the burner body 1. A spring 132 is fixedly connected to the upper side of the horizontal plate 131. A cleaning plate 133 is fixedly connected to the side of the spring 132 away from the horizontal plate 131. A collection box 135 is provided on the right side of the cleaning plate 133. A guide plate 134 is fixedly connected to the left side of the collection box 135. The cleaning plate 133 is located on the lower side of the grate conveyor 12.

[0030] Specifically, the slag produced after the fuel burns on the grate conveyor 12 gradually falls off as the grate conveyor 12 moves. The cleaning plate 133 is located under the grate conveyor 12 and is connected to the horizontal plate 131 by the spring 132, which has an elastic buffering function. When the slag falls onto the cleaning plate 133, its gravity causes the cleaning plate 133 to press down the spring 132, and under the drive of the grate conveyor 12, the slag is guided to the guide plate 134 on the right side, and finally the slag slides into the collection box 135. This process does not require manual intervention and automatically completes the cleaning and collection of slag, reducing the intensity of manual labor, keeping the inside of the equipment clean, and ensuring the continuous and stable operation of the burner.

[0031] Working principle: When using this device, fuel enters the burner body 1 through the feed port 14 and is burned on the grate conveyor 12. Part of the heat generated by combustion is used to heat the medium in the furnace body 2, and the other part is conducted to the heat conduction plate 3 through the outside of the burner body 1. The heat conduction plate 3 is in close contact with the burner body 1 and can effectively absorb heat and transfer it to the cold water pipe 5 that is close to its right side. The cold water pipe 5 introduces cold water through the water inlet pipe 15. After the cold water absorbs heat in the pipe, it is discharged as hot water through the water outlet pipe 16, thereby cooling the burner body 1 and recovering and utilizing the heat.

[0032] The controller 17 starts the fan 6, which draws in outside air. The air first passes through the filter box 7. The filter screen 8 on the left side of the filter box 7 intercepts large particulate impurities in the air, while the activated carbon screen 9 on the right side adsorbs odors and small particles. The purified air enters from the left side of the fan 6 and is then transported to the furnace body 2 from the right side, providing sufficient oxygen for combustion. The flue gas produced by combustion also mixes with the air in the furnace body 2, promoting complete combustion.

[0033] The slag after the fuel is burned on the grate conveyor 12 gradually falls off as the grate conveyor 12 moves. The cleaning plate 133 is located on the lower side of the grate conveyor 12 and is connected to the horizontal plate 131 by the spring 132. It has a certain elasticity. When the slag falls on the cleaning plate 133, the cleaning plate 133 presses down on the spring 132 under the action of the slag's gravity. As the grate conveyor 12 moves, it guides the slag to the guide plate 134 on the right side and finally slides into the collection box 135, realizing the automatic cleaning and collection of slag.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
