[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] Please see Figure 1-3 In this embodiment of the invention, an energy-saving burner device for a sintering machine includes: Ignition device 1; The base plate 2 has a material loading groove 3. The material is placed inside the material loading groove 3, and the igniter 1 works to sinter the material. The processing tube 4 has a processing chamber 5 on the base plate 2. The processing chamber 5 is connected to the processing tube 4. The inlet of the processing tube 4 is set towards the igniter 1. A fan 6 is fixedly connected inside the processing chamber 5. The processing chamber 5 is connected to the material trough 3 through a connecting hole 7. A material net 8 is fixedly connected inside the connecting hole 7. The mesh of the material net 8 is small enough to prevent the material above the material net 8 from falling. When the igniter 1 is working, heat is generated nearby. The fan 6 operates to send the heat through the processing tube 4, the processing chamber 5, and the material net 8 into the bottom of the material trough 3. The heat is used to sinter the material at the bottom of the material trough 3.

[0020] A fixing plate 10 is fixedly connected to the top of the base plate 2 via a support plate 9, and the igniter 1 is fixedly connected to the fixing plate 10.

[0021] A filter screen 11 is fixedly connected to the inlet of the processing pipe 4. The material is placed inside the material loading tank 3. The igniter 1 works to sinter the material. Heat is generated near the igniter 1 when it is working. The fan 6 works to send the heat through the processing pipe 4, the processing chamber 5, and the material loading screen 8 to the bottom of the material loading tank 3. The heat is used to sinter the material at the bottom of the material loading tank 3. Since flue gas impurities will be generated during the sintering process of the igniter 1, the filter screen 11 filters the flue gas impurities to prevent them from entering the interior of the processing pipe 4.

[0022] A heat insulation cover 12 is movably connected above the base plate 2. The igniter 1 is movably connected relative to the heat insulation cover 12. The material of the heat insulation cover 12 is heat insulation material. During the sintering process of the material by the igniter 1, the heat insulation cover 12 moves downward and completely covers the sintering process of the material, thus achieving the function of heat preservation and energy saving.

[0023] A pneumatic telescopic rod 13 is fixedly connected to the fixed plate 10. A U-shaped movable rod 14 is fixedly connected to the moving end of the pneumatic telescopic rod 13. The vertical end of the U-shaped movable rod 14 passes through the fixed plate 10 and is fixedly connected to the heat insulation cover 12. The heat insulation cover 12 is made of heat insulation material. During the sintering process of the material by the igniter 1, the pneumatic telescopic rod 13 works to make the U-shaped movable rod 14 move downward. During the downward movement of the U-shaped movable rod 14, the heat insulation cover 12 moves downward. The heat insulation cover 12 completely covers the sintering process of the material, achieving the effect of heat preservation and energy saving.

[0024] A connecting rod 15 is fixedly connected to the heat insulation cover 12, and a cleaning plate 16 is fixedly connected to the connecting rod 15. The cleaning plate 16 cooperates with the filter screen 11 to place the material inside the loading tank 3. The igniter 1 operates to sinter the material. Heat is generated near the igniter 1 during operation, and the fan 6 operates to send the heat through the processing pipe 4, processing chamber 5, and loading screen 8 into the bottom of the loading tank 3. The heat sinters the material at the bottom of the loading tank 3. Since flue gas impurities will be generated during the sintering process of the igniter 1, the filter screen 11 filters the flue gas impurities. To prevent impurities in the flue gas from entering the interior of the treatment pipe 4, the impurities in the flue gas adhere to the filter screen 11. The pneumatic telescopic rod 13 works to make the U-shaped movable rod 14 move up and down in the vertical direction. During the up and down movement of the U-shaped movable rod 14, the heat insulation cover 12 moves up and down. During the up and down movement of the heat insulation cover 12, the connecting rod 15 moves upward. During the up and down movement of the connecting rod 15, the cleaning plate 16 moves up and down. When the cleaning plate 16 acts on the side wall of the filter screen 11, the flue gas impurities on the filter screen 11 are cleaned by the cleaning plate 16.

[0025] The fixed plate 10 has a storage cavity 17 inside, and the heat insulation cover 12 has a cooling cavity 18 inside. The cooling cavity 18 and the storage cavity 17 are connected by a liquid flow pipe 19, and the bottom of the liquid flow pipe 19 has a liquid outlet 24.

[0026] The top end of the flow tube 19 is fixedly connected to the fixed plate 10, and the bottom end of the flow tube 19 is fixedly connected to the push plate 20. The push plate 20 is sealed and movable inside the storage cavity 17, and the bottom of the cooling cavity 18 is fixedly connected to the heat dissipation plate 21.

[0027] The heat sink 21 and push plate 20 are made of thermally conductive material, while the insulation cover 12 is made of heat-insulating material. When the material in the loading tank 3 has completed the sintering process, the igniter 1 stops working. In order to prevent the residual high temperature near the loading tank 3 from further affecting the material, cooling treatment is required. The pneumatic telescopic rod 13 works to move the U-shaped movable rod 14 vertically. During the upward movement of the U-shaped movable rod 14, the insulation cover 12 moves upward, meaning that the insulation cover 12 does not cover the material, which facilitates the air circulation near the material in the loading tank 3. At the same time, during the upward movement of the insulation cover 12, the push plate 20 moves relatively downward inside the cooling chamber 18, meaning that the coolant inside the storage chamber 17 flows into the cooling chamber 18 through the flow pipe 19 and the outlet 24. Since the heat sink 21 and push plate 20 are made of thermally conductive material, the coolant achieves the cooling effect on the material near the loading tank 3, preventing the residual high temperature from the igniter 1 from affecting the material.

[0028] Working principle: During the sintering process of the material by the igniter 1, the pneumatic telescopic rod 13 works to make the U-shaped movable rod 14 move downward. During the downward movement of the U-shaped movable rod 14, the heat insulation cover 12 moves downward. The heat insulation cover 12 completely covers the sintering process of the material, achieving the effect of heat preservation and energy saving.

[0029] The material is placed inside the material loading tank 3. The igniter 1 operates to sinter the material. Heat is generated near the igniter 1 during operation. The fan 6 operates to send the heat through the processing pipe 4, processing chamber 5, and material loading mesh 8 to the bottom of the material loading tank 3. The heat is used to sinter the material at the bottom of the material loading tank 3, thus realizing the utilization of heat and achieving the effect of energy saving. Since flue gas impurities will be generated during the sintering process of the igniter 1, the filter mesh 11 filters the flue gas impurities to prevent them from entering the interior of the processing pipe 4.

[0030] When the material in the loading tank 3 has completed the sintering process, the igniter 1 stops working. In order to prevent the residual high temperature near the loading tank 3 from further affecting the material, cooling treatment is required. The pneumatic telescopic rod 13 works to move the U-shaped movable rod 14 vertically. During the upward movement of the U-shaped movable rod 14, the heat insulation cover 12 moves upward, meaning that the heat insulation cover 12 does not cover the material, which facilitates the air circulation near the material in the loading tank 3. At the same time, during the upward movement of the heat insulation cover 12, the push plate 20 moves downward relative to the inside of the cooling chamber 18, which means that the coolant in the storage chamber 17 flows into the inside of the cooling chamber 18 through the flow pipe 19 and the outlet 24. Since the heat dissipation plate 21 and the push plate 20 are made of thermally conductive materials, the coolant achieves the cooling effect on the material near the loading tank 3, preventing the residual high temperature from the igniter 1 from affecting the material.

[0031] Therefore, impurities in the flue gas adhere to the filter screen 11. The pneumatic telescopic rod 13 works to make the U-shaped movable rod 14 move up and down in the vertical direction. During the up and down movement of the U-shaped movable rod 14, the heat insulation cover 12 moves up and down. During the up and down movement of the heat insulation cover 12, the connecting rod 15 moves upward. During the up and down movement of the connecting rod 15, the cleaning plate 16 moves up and down. When the cleaning plate 16 acts on the side wall of the filter screen 11, the flue gas impurities on the filter screen 11 are cleaned by the cleaning plate 16. Example 2

[0032] The following technical features are added based on Embodiment 1; An energy-saving burner device for a sintering machine has a gas pipe 22 fixedly connected through a storage chamber 17. The gas pipe 22 is connected to a processing pipe 4. A control valve 23 is installed on the gas pipe 22. When the operator opens the control valve 23, the fan 6 operates, allowing air to enter the material tank 3 through the gas pipe 22, the processing pipe 4, the processing chamber 5, and the connecting hole 7. This achieves heat dissipation treatment for the material at the bottom of the material tank 3. At the same time, since a part of the gas pipe 22 is located inside the storage chamber 17 and the material of the gas pipe 22 is a thermally conductive material, the temperature of the coolant inside the storage chamber 17 is also reduced.

[0033] Working principle: During the sintering process of the material by the igniter 1, the pneumatic telescopic rod 13 works to make the U-shaped movable rod 14 move downward. During the downward movement of the U-shaped movable rod 14, the heat insulation cover 12 moves downward. The heat insulation cover 12 completely covers the sintering process of the material, achieving the effect of heat preservation and energy saving.

[0034] The material is placed inside the material loading tank 3. The igniter 1 operates to sinter the material. Heat is generated near the igniter 1 during operation. The fan 6 operates to send the heat through the processing pipe 4, processing chamber 5, and material loading mesh 8 to the bottom of the material loading tank 3. The heat is used to sinter the material at the bottom of the material loading tank 3, thus realizing the utilization of heat and achieving the effect of energy saving. Since flue gas impurities will be generated during the sintering process of the igniter 1, the filter mesh 11 filters the flue gas impurities to prevent them from entering the interior of the processing pipe 4.

[0035] When the material in the loading tank 3 has completed the sintering process, the igniter 1 stops working. In order to prevent the residual high temperature near the loading tank 3 from further affecting the material, cooling treatment is required. The pneumatic telescopic rod 13 works to move the U-shaped movable rod 14 vertically. During the upward movement of the U-shaped movable rod 14, the heat insulation cover 12 moves upward, meaning that the heat insulation cover 12 does not cover the material, which facilitates the air circulation near the material in the loading tank 3. At the same time, during the upward movement of the heat insulation cover 12, the push plate 20 moves downward relative to the inside of the cooling chamber 18, which means that the coolant in the storage chamber 17 flows into the inside of the cooling chamber 18 through the flow pipe 19 and the outlet 24. Since the heat dissipation plate 21 and the push plate 20 are made of thermally conductive materials, the coolant achieves the cooling effect on the material near the loading tank 3, preventing the residual high temperature from the igniter 1 from affecting the material.

[0036] When the staff opens the control valve 23, the fan 6 starts working, allowing air to enter the material tank 3 through the air pipe 22, the processing pipe 4, the processing chamber 5, and the connecting hole 7, thus achieving heat dissipation treatment for the material at the bottom of the material tank 3. At the same time, since part of the air pipe 22 is located inside the storage chamber 17, and the material of the air pipe 22 is a heat-conducting material, the temperature of the coolant inside the storage chamber 17 is also reduced.

[0037] Therefore, impurities in the flue gas adhere to the filter screen 11. The pneumatic telescopic rod 13 works to make the U-shaped movable rod 14 move up and down in the vertical direction. During the up and down movement of the U-shaped movable rod 14, the heat insulation cover 12 moves up and down. During the up and down movement of the heat insulation cover 12, the connecting rod 15 moves upward. During the up and down movement of the connecting rod 15, the cleaning plate 16 moves up and down. When the cleaning plate 16 acts on the side wall of the filter screen 11, the flue gas impurities on the filter screen 11 are cleaned by the cleaning plate 16.

[0038] In this invention, "fixed connection" means that two interconnected parts are fixed together, generally by means of welding, screws or adhesive; "rotational connection" means that two parts are connected together and can move relative to each other.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0040] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
