Description

Technical Field

[0001] This utility model relates to the field of conveyor system technology, and specifically to a belt conveyor system with a sealing structure. Background Technology

[0002] Incineration of municipal solid waste has become a widely used method, requiring a waste incinerator. The incinerator burns municipal solid waste in its furnace, producing exhaust gases that enter a secondary combustion chamber for complete combustion under forced combustion. The exhaust gases then enter a flue gas purification system for acid removal and dust removal, before being released into the atmosphere through a chimney. As a highly efficient waste treatment method, waste incineration converts waste into ash, flue gas, and heat energy through high-temperature combustion, achieving the goals of waste reduction, harmlessness, and resource recovery.

[0003] However, the current ash removal systems in waste incineration plants, especially the ash conveying system at the boiler's zero-meter level, are characterized by multiple ash removal machines and two long ash conveying belts (approximately 110 meters each). Since both the ash removal machine outlets and the conveying belts are open, this area is constantly plagued by dust and moisture, severely impacting environmental sanitation and causing corrosion to surrounding equipment. Therefore, to effectively control these dust and moisture emissions, waste incinerators need to be equipped with a closed ash removal system. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a belt conveyor system with a sealed structure. This belt conveyor system with a sealed structure significantly reduces the corrosivity of the ash and slag conveying system area and surrounding equipment, greatly improves the cleanliness of the equipment, and significantly improves the working environment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The sealed structure is provided with a lighting system and a spray system. The lighting system is located on both sides of the upper part of the sealed structure, and the spray system is located in the upper middle part of the sealed structure. The inner top of the sealed structure is provided with a main air duct that communicates with an external dust removal and exhaust system.

[0007] Furthermore, in this invention, the belt conveyor system is provided with a sealing wall around its perimeter, and a sealing plate is provided on the sealing wall; a sealing plate is provided on the top of the belt conveyor system.

[0024] Example

[0025] Please see Figures 1 to 3 A belt conveyor system with a sealed structure includes a belt conveyor system with sealing walls 1 and sealing plates 2 on all four sides and top. The sealing walls 1 and sealing plates 2 form a sealed structure to completely seal the belt conveyor system. Specifically, it completely seals two long belt conveyors, eight reversible belt conveyors 15 mounted on the two long belt conveyors, and the slag outlet of the slag remover 3. The sealed structure is 8 meters high, 120 meters long, and 8 meters wide, with an area of ​​2048 square meters. Figure 2 and Figure 3 ,in Figure 2This is a structural diagram of a segment inside the sealed structure (because the entire belt conveyor system is too long and the internal structures are all the same, only a partial enlarged view of a segment is shown in the figure). Figure 3 The diagram shows a top-view internal structure of a section connected to the dust extraction system (the internal structure diagrams of other sections are the same as those shown in this diagram). The sealed structure contains a lighting system and a spray system. The lighting system is located on both sides of the upper part of the sealed structure, while the spray system is located in the upper middle part of the sealed structure, i.e., below the lighting system, to prevent the lighting system from being wetted by the spray system and affecting its illumination. The top of the sealed structure has a main duct 6 that connects to the external dust extraction system. The main duct 6 has a diameter of 800 mm and a length of approximately 128 meters.

[0026] As a further specific technical solution, the sealing structure of the belt conveyor system consists of a combination of a sealing wall 1 and a sealing plate 2. Specifically, the sealing wall 1 is formed using a brick-concrete structure (reinforced concrete and lightweight bricks) for heights below 3 meters, with its bottom fixed by a concrete ground beam. Above 3 meters, the sealing plate 2 is formed using a lightweight steel structure (aluminum keel and aluminum sandwich panels). Therefore, the height of the sealing wall 1 is 3 meters, and the height of the sealing plate 2 on the sealing wall 1 is 5 meters. The top of the belt conveyor system is covered by the sealing plate 2 on the surrounding sealing structure. Furthermore, the sealing plate 2 is coated with an anti-corrosion layer. This design improves the sealing effect of the sealing structure, facilitates construction, and extends its service life.

[0027] As a further specific technical solution, in order to facilitate on-demand maintenance of the belt conveyor system and its internal lighting system, sprinkler system, etc., and to observe the situation inside the sealed structure as needed, the sealed wall 1 is provided with multiple maintenance doors 4 and observation windows 5 that are spaced apart and easy to open or close.

[0028] As a further specific technical solution, the spraying system includes a main spray pipe 9 and multiple spray branch pipes 10 respectively connected to the main spray pipe 9. The main spray pipe 9 is arranged in the middle of the top of the sealed structure and extends outward to connect with an external water source and a drive device. The multiple spray branch pipes 10 extend downward and are arranged in the upper middle part of the sealed structure. The ends of the spray branch pipes 10 are equipped with nozzles 11 to spray the inside of the sealed structure to reduce dust and cool down, which achieves a good effect of avoiding dust.

[0029] As a further specific technical solution, the lighting system includes lighting rows installed on the upper left and right sides of the sealed structure. The lighting rows on the left and right sides are symmetrically arranged, and each lighting row includes multiple lighting lamps (12 lamps in total, 14 lamps on the left and 14 lamps on the right, for a total of 28 lamps). This ensures sufficient lighting inside the sealed structure, facilitating observation of the operation of the belt conveyor system within the sealed structure. The lighting rows on the left and right sides are connected in parallel and can be turned on or off as needed to achieve energy-saving effects.

[0030] As a further specific technical solution, the dust removal and exhaust system includes a cyclone dust collector 13 and a dust removal exhaust fan 14 connected together, and the main air duct 6 is connected to the cyclone dust collector 13. Multiple exhaust branch pipes 7 are connected to the main air duct 6, and the exhaust branch pipes 7 are connected to the suction port of the slag remover 3. The diameter of the exhaust branch pipes 7 is 350mm, and the main air duct 6 and the exhaust branch pipes 7 are also equipped with regulating dampers 8.

[0031] In addition, to improve the service life of the ducts, considering strength and corrosion resistance, the main duct 6 and the exhaust branch duct 7 are made of galvanized ducts or fiberglass ducts. In this embodiment, fiberglass ducts are preferred.

[0032] This invention, by setting a sealing structure outside the belt conveyor system used for slag conveying, completely eliminates dust and moisture in the boiler's 0-meter layer area, especially in the first section of the slag conveying system. Simultaneously, the control of dust and moisture significantly reduces corrosion in the slag conveying system area and surrounding equipment, greatly improves equipment cleanliness, and significantly enhances the working environment, resulting in a substantial improvement in the plant's appearance. Furthermore, by incorporating a spray system, lighting system, and a main air duct 6 connected to the cyclone dust removal system within the sealed structure, not only is the belt conveyor system able to operate normally, but the large amount of dust and easy corrosion and aging of equipment within the sealed structure are also avoided, and observation and maintenance are facilitated.
