Description

Technical Field

[0001] This utility model relates to the field of fuel drying technology, and in particular to a biomass fuel dryer. Background Technology

[0002] Biomass fuel dryers are specialized equipment for processing biomass raw materials such as straw and sawdust. They are primarily used to remove moisture from these materials to improve their combustion efficiency and storage stability. In the biomass energy conversion industry chain, this equipment is a crucial link connecting raw material collection and fuel molding. Through standardized processing of wet materials, it provides qualified raw materials for subsequent compression molding, combustion power generation, and other processes. It is widely used in biomass energy production enterprises, agricultural waste treatment plants, and other similar locations.

[0003] Existing dryers typically consist of a machine body, a drying chamber, and a heating device. The drying chamber is a closed processing space with a storage tray inside to hold the material. The heating device is usually a hot air blower, which delivers hot air to evaporate the moisture in the material. The material to be dried enters the storage tray inside the drying chamber through a conveyor assembly. The heating device is adjusted to a set height, and the hot air blower continuously delivers hot air into the drying chamber. Under the action of the hot air, the moisture in the material gradually evaporates, and after drying is complete, the material is discharged.

[0004] The existing technology has significant drawbacks in adjusting the heating process. Existing technologies often use a single hot air blower for heating, which cannot achieve overall height adjustment of the heating device. It also cannot adjust the height locally according to the dryness or wetness of materials in different areas of the drying chamber. This results in poor uniformity of material heating, inconsistent drying efficiency, insufficient positioning accuracy of the heating device, and an inability to maintain the optimal drying distance from the material, directly affecting the stability of the drying quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a biomass fuel dryer, which aims to improve the problem of uneven heating of materials caused by the inability to achieve local height adjustment in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a biomass fuel dryer, comprising a body, a drying chamber fixedly connected to one side of the body, a base fixedly connected to the bottom of the body, a lifting assembly inside the body, and a feeding assembly on one side of the base;

[0007] The lifting assembly includes multiple base plates, each fixedly connected to one side of the machine body. Multiple motors are rotatably connected to one side of each base plate.

[0010] As a further description of the above technical solution:

[0011] Each of the multiple fixing blocks has a connecting post fixedly connected inside. A ratchet is fixedly connected to the outer wall of the connecting post, and a pawl is slidably connected to the outer wall of the connecting post. The ratchet and the pawl engage.

[0012] As a further description of the above technical solution:

[0013] A storage drawer is slidably connected to one side of the pawl, and multiple push plates are slidably connected to one side of one of the storage drawers. Fixed columns are slidably connected inside the multiple storage drawers.

[0014] As a further description of the above technical solution:
