Description

Technical Field

[0001] This application relates to the field of sludge drying and incineration treatment equipment, and more particularly to a municipal sludge drying and incineration treatment system. Background Technology

[0002] Existing municipal sludge drying and incineration treatment equipment typically includes a drying unit, an incineration unit, and an exhaust gas treatment unit. The drying unit includes a conveying mechanism and a hot air circulation mechanism. The sludge is conveyed on the conveying mechanism and then dried by the hot air circulation mechanism. The conveying mechanism then conveys the dried sludge to the incineration unit for incineration. However, because the sludge is already dried, it tends to adhere to the conveying mechanism during transport, making it difficult to transport to the incineration unit. Utility Model Content

[0003] To facilitate the transport of dried sludge to the incineration unit, this application provides a municipal sludge drying and incineration treatment system.

[0004] This application provides a municipal sludge drying and incineration treatment system, which adopts the following technical solution:

[0005] A municipal sludge drying and incineration treatment system includes a drying device, an incineration device, and a tail gas treatment device. The drying device is used to dry the sludge and transport it to the incineration device. The incineration device is used to treat the dried sludge. The tail gas treatment device is connected to the incineration device to treat the combustion tail gas. The drying device includes a conveying mechanism and a hot air circulation mechanism. The conveying mechanism includes a frame, conveying rollers, and a conveyor belt. Two conveying rollers are provided and distributed along the length of the frame. The axis of the conveying rollers is parallel to the width of the frame, and both ends of the conveying rollers are rotatably connected to the frame. The conveyor belt is wound around the two conveying rollers. A guide plate is provided at the discharge end of the frame, and the side of the guide plate near the feed end of the frame abuts against the upper surface of the conveyor belt.

[0006] By adopting the above technical solution, a guide plate is provided, and one end of the guide plate abuts against the conveyor belt. When the conveyor belt rotates, the sludge on the conveyor belt will be conveyed to the guide plate. Since the guide plate abuts against the upper surface of the conveyor belt, it will hang the sludge attached to the conveyor belt, reducing the residue of sludge.

[0007] Optionally, the frame is provided with mounting frames on both sides of the guide plate, the two sides of the guide plate are connected to the mounting frames, and an intermittent conveying assembly is provided between the two mounting frames. The intermittent conveying assembly can convey the sludge on the guide plate in a direction away from the conveyor belt.

[0008] By adopting the above technical solution, when too much sludge accumulates on the guide plate, it will affect the sludge transportation. Therefore, an intermittent transportation component is set up to assist in the transportation of sludge.

[0009] Optionally, the intermittent conveying assembly includes a rotating shaft, a first conveying plate, and a drive motor. The two ends of the rotating shaft are rotatably connected to two mounting brackets, and a plurality of the first conveying plates are arranged in a circular array around the axis of the rotating shaft. The drive motor drives the rotating shaft to rotate.

[0010] By adopting the above technical solution, the rotating shaft is driven by a drive motor to rotate, and the rotating shaft drives several first conveying plates to rotate. During the rotation, the first conveying plates will move the sludge on the guide plate, thereby assisting in the transportation of the sludge.

[0011] Optionally, the first conveyor plate is provided with a second conveyor plate, the second conveyor plate being located on the side of the first conveyor plate away from the rotation axis, and the second conveyor plate being slidably connected to the first conveyor plate in a direction close to the rotation axis.

[0012] By adopting the above technical solution, the second conveying plate can slide relative to the first conveying plate. During the rotation, the second conveying plate slides downward, so that the lower end of the second conveying plate abuts against the guide plate in advance. During the abutment process, the second conveying plate can slide adaptably, thereby increasing the auxiliary conveying time of the second conveying plate and improving the efficiency of the guide plate in conveying sludge.

[0013] Optionally, the first conveyor plate is provided with an elastic element that forces the second conveyor plate to slide away from the rotation axis.

[0014] By adopting the above technical solution and incorporating an elastic element, the lower end of the second conveyor plate is always in contact with the upper surface of the guide plate.

[0015] Optionally, the second conveyor plate is provided with an abutment plate at the end away from the first conveyor plate, and the abutment plate is elastically configured.

[0016] Optionally, the abutment plate includes a connecting portion and an abutment portion. The connecting portion is used to connect with the second conveyor plate, and the abutment portion is used to abut with the guide plate. The connecting portion and the abutment portion are set at an obtuse angle. One end of the abutment portion is connected to the connecting portion, and the other end of the abutment portion extends away from the conveyor belt.

[0017] By adopting the above technical solution, one end of the abutting part is connected to the connecting part, and the other end extends away from the conveyor belt, so that the second conveying plate can better convey the sludge on the guide plate towards the discharge port during the rotation process.

[0018] Optionally, the cross-section of the abutment portion is triangular.

[0019] By adopting the above technical solution, the abutment part is triangular, which allows the abutment part to better scrape the sludge on the guide plate toward the discharge port.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. A guide plate is provided, with one end of the guide plate abutting against the conveyor belt. When the conveyor belt rotates, the sludge on the conveyor belt will be conveyed to the guide plate. Since the guide plate abuts against the upper surface of the conveyor belt, it will hang the sludge attached to the conveyor belt, reducing the residue of sludge.

[0022] 2. The rotating shaft is driven by a drive motor to rotate, and the rotating shaft drives several first conveyor plates to rotate. During the rotation, the first conveyor plates will move the sludge on the guide plate, thereby assisting in the transportation of the sludge. Attached Figure Description
