Technical Field

[0001] The present application relates to the technical field of slag discharge doors, and more specifically, to a self-cleaning slag discharge door. Background Art

[0002] In the construction of construction projects, when it comes to boilers, combustion equipment, sewage treatment equipment and other fields, the slag discharge door is a key component used to handle the waste slag generated to ensure the smooth progress of the construction process. During the boiler construction process, especially for boilers burning coal, oil and other fuels, ash and smoke will be generated during the combustion process. These waste slags need to be discharged in time to ensure the normal operation of the boiler. The slag discharge door is installed at the bottom of the boiler. By opening the slag discharge door, the operator can discharge the ash from the boiler, keep the boiler combustion chamber clean, and improve combustion efficiency and safety.

[0003] During the combustion process, impurities and combustion products in the fuel will form ash. Some of the ash may clump near the slag discharge door. These agglomerated ash will block the slag discharge door, resulting in poor slag discharge or complete inability to discharge. If the moisture content in the fuel is too high, or if water vapor condenses into water droplets and adheres to the ash when the boiler is running, the viscosity of the ash will increase, making it easier to adhere to the inner wall or door of the slag discharge door, causing blockage. Therefore, some slag discharge operations require staff to assist in discharging the residue, which is time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0032] Reference Figure 1-Figure 5 , a self-cleaning slag discharge door, comprising a tank body 1 and a slag discharge door 2, wherein a cleaning component is provided inside the slag discharge door 2;

[0033] The cleaning assembly includes a connecting rod 18. A slag blocking plate 6 is provided inside the slag discharge door 2. The connecting rod 18 is rotatably connected to the slag discharge door 2 and the slag blocking plate 6. The top of the connecting rod 18 is fixedly connected to the connecting plate 7. The bottom of the connecting plate 7 is fixedly connected to the scraper 19. The scraper 19 is located at the top of the slag blocking plate 6 and is in contact with the slag blocking plate 6. The middle end of the connecting rod 18 is connected to a ventilation plate 9.

[0034] By setting up the cleaning component, the ash and slag on the surface of the slag retaining plate 6 inside the slag discharge door 2 can be automatically scraped off, reducing the occurrence of adhesion during slag discharge. Even if adhesion occurs during slag discharge, the difficulty of cleaning for the staff can be reduced, thereby improving the slag removal efficiency.

[0035] Reference Figure 1-Figure 4 The cleaning assembly also includes an air nozzle 16. A plurality of air nozzles 16 are connected to the top of the ventilation plate 9. A check valve 17 is provided inside each air nozzle 16. The connecting plate 7 corresponds to the position of the air nozzle 16. The plurality of air nozzles 16 are located at the bottom of the slag retaining plate 6.

[0036] When slag discharge is required, the slag discharge door 2 is opened to a horizontal state. At this time, the second motor 11 rotates, thereby driving the connecting rod 18 to rotate. When the connecting rod 18 rotates, it drives the scraper 19 and the air nozzle 16 on the vent plate 9 to rotate synchronously. While scraping the slag on the slag retaining plate 6, the air nozzle 16 sprays compressed air to generate airflow. The airflow will be sprayed onto the surface of the slag retaining plate 6, exerting pressure on the adhered slag, and the sprayed airflow will blow the slag on the surface of the slag retaining plate 6 away. The auxiliary scraper 19 removes the slag from the slag retaining plate 6 and pushes it to the outside of the slag discharge door 2 to achieve automatic cleaning.

[0037] In the air nozzle 16, the function of the check valve 17 is to ensure that the injected compressed air or other medium can only be injected outwards, and will not flow in the reverse direction or enter the inside of the air nozzle 16. This can ensure that the air nozzle 16 works normally during the slag discharge process.

[0038] Reference Figure 4-Figure 5 A sealing box 8 is fixedly connected to the bottom of the slag discharge door 2, and a second motor 11 is arranged inside the sealing box 8. The output end of the second motor 11 is connected to a driving gear 14 through a rotating shaft. One end of a connecting rod 18 extends through the interior of the sealing box 8 and is fixedly connected to a driven gear 15. The driving gear 14 is meshed with the driven gear 15. The bottom end of the connecting rod 18 is connected to a rotary joint 12, and the bottom end of the rotary joint 12 is connected to a docking pipe 13, which extends through the outside of the sealing box 8.

[0039] When cleaning is required, the second motor 11 drives the driving gear 14 to rotate, the driving gear 14 drives the driven gear 15 to rotate, and the driven gear 15 drives the connecting rod 18 to rotate. At this time, the pipeline of the external gas source is docked with the docking pipe 13, and the gas is transported to the inside of the ventilation plate 9 on one side of the connecting rod 18 through the rotating joint 12, and is sprayed out through the gas nozzle 16.

[0040] Reference Figure 1-Figure 3 One end of the slag baffle plate 6 is fixedly connected to a blocking block 10, one end of the tank body 1 is provided with a connecting block 4, one side of the connecting block 4 is provided with a first motor 3, the output end shaft of the first motor 3 is rotatably connected to the connecting block 4, the outer wall of the shaft is fixedly connected to a fixing block 5, the fixing block 5 is fixedly connected to the slag discharge door 2, an electric push rod 20 is provided at the end of the tank body 1 away from the first motor 3, the end of the tank body 1 away from the first motor 3 is fixedly connected to a block 23, one end of the block 23 is connected to a rotating block 21 through a rotating shaft, the output end of the electric push rod 20 is rotatably connected to the rotating block 21, and a clamping block 22 is fixedly connected to the bottom of the slag discharge door 2, and one end of the clamping block 22 is located on the inner side of the rotating block 21.

[0041] When the slag blocking plate 6 is not cleaned, the air nozzle 16 and the scraper 19 are always located at the upper and lower ends of the blocking block 10 to prevent a small amount of waste slag from entering the interior of the air nozzle 16 .

[0042] When slag discharge is required, the first motor 3 drives the fixed block 5 to rotate, and the fixed block 5 drives the slag discharge door 2 to open. At this time, the electric push rod 20 drives the rotating block 21 to rotate, so that the clamping block 22 is separated from the inner side of the rotating block 21, and the first motor 3 will drive the slag discharge door 2 to rotate to a horizontal state, which is convenient for slag discharge.

[0043] Working principle: When discharging slag, the first motor 3 is used to drive the fixed block 5 to rotate, and the fixed block 5 drives the slag discharge door 2 to open. At this time, the electric push rod 20 drives the rotating block 21 to rotate, so that the blocking block 22 is separated from the inner side of the rotating block 21, and the first motor 3 will drive the slag discharge door 2 to rotate to a horizontal state. At this time, the second motor 11 rotates, and then drives the connecting rod 18 to rotate. When the connecting rod 18 rotates, it drives the scraper 19 and the air nozzle 16 on the vent plate 9 to rotate synchronously. While scraping the slag on the slag baffle plate 6, the air nozzle 16 sprays compressed air to generate airflow, which will be sprayed onto the surface of the slag baffle plate 6 to apply pressure to the adhered slag. The sprayed airflow will blow away the slag on the surface of the slag baffle plate 6, and then assist the scraper 19 to remove the slag from the slag baffle plate 6 and push it to the outside of the slag discharge door 2 to achieve automatic cleaning.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
