Description

Technical Field

[0001] The utility model relates to the technical field of spray drying furnaces, in particular to an energy-saving and environment-friendly scale collecting box for spray drying furnaces. Background Art

[0002] Spray drying oven is a heating device in the heating and drying process, or called a drying room. Different types of drying ovens have different structures and heating methods. According to their appearance and structure, they can be divided into box type (oven), chamber type (drying room), and through type (also divided into straight-through type and bridge type). Box type and chamber type are suitable for single piece or small batch production. Through type is suitable for large-scale assembly line production. The coated object is placed on a conveyor and passes through a tunnel-like drying room at a certain speed;

[0003] A Chinese patent with publication number CN218380394U was searched and disclosed a scale collecting box for an internal spray drying furnace.

[0004] The above technical solution includes a shaking box, a dirt collecting box, a bottom plate, a dirt collecting mechanism and a driving shaking mechanism. A dirt collecting box is provided on one side of the shaking box. A slide groove is provided on one side of the shaking box, and the dirt collecting mechanism is provided in the dirt collecting box. The driving shaking mechanism is provided on the dirt collecting box and the shaking box. Beneficial effect: The ash slag is collected by the provided dirt collecting mechanism to prevent it from polluting the working environment. The ash slag can be quickly cleaned by pulling the dirt collecting pull-out box with a handle. The driving shaking mechanism can be used to rotate the cam to intermittently squeeze the connecting block, so that the connecting block and the dirt collecting box move synchronously to one side. When the cam is away from the connecting block, the connecting block is reset under the action of the spring force. This reciprocating process allows the dirt collecting box to shake left and right, so that the ash slag in the dirt collecting box and the dirt collecting pull-out box can be shaken evenly, which can increase the collection amount and efficiency of the ash slag.

[0005] However, in the above scheme, the technology shakes the shaking box by rotating the cam to evenly shake the ash, but the cam structure is easily worn and has a short service life. In addition, when there is a lot of ash, the load is large and the power requirement is high. When the dirt collecting box is pulled out, the weight of the box body and the ash is heavy, which is very laborious. In addition, there are blind spots in the structure of the box body, which is inconvenient to clean.

[0006] Therefore, we propose an energy-saving and environment-friendly scale collecting box for spray drying furnace. Utility Model Content
