Description
Technical Field
[0001] This utility model relates to the field of filter dryer technology, and in particular to a cone-type filter dryer. Background Technology
[0002] In industries such as chemical, pharmaceutical, food, and environmental protection, filtration and drying are two crucial process steps. With the advancement of technology and the increasing demands of production, traditional filtration and drying equipment can no longer meet the requirements of efficient, energy-saving, and environmentally friendly modern production. As a new type of equipment that integrates filtration, washing, drying, and unloading, the cone filter dryer has been widely used and recognized in these fields due to its unique structure and excellent performance. As a key piece of equipment, the filter dryer undertakes the dual tasks of material filtration and drying. Its performance directly affects production efficiency, product quality, and production costs. However, no equipment is perfect, and the cone filter dryer has also revealed some structural deficiencies and drawbacks during use.
[0003] In terms of the structure of existing filter dryers, due to unreasonable structural design, some filter dryers have difficulty achieving uniform heating during the drying process, resulting in uneven drying of materials, affecting product quality and subsequent processing. Secondly, the agitation system design of some cone filter dryers is unreasonable, resulting in uneven agitation, which affects the filtration and drying effect of materials. At the same time, filter dryers are prone to material accumulation during filtration and drying, leading to blockages. This not only affects the normal operation of the equipment, but may also cause material waste and a decline in product quality. Utility Model Content
