Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a petrochemical solid material drying device. Background Art

[0002] In the field of petrochemicals, the drying of solid materials is a key process step. Traditionally, solid materials are dried mainly by hot air drying, rotary drying and other methods. Although these traditional drying methods are easy to operate, they have problems such as high energy consumption, low drying efficiency and poor drying uniformity. In addition, they may also cause thermal decomposition of materials or changes in chemical properties, which have an adverse effect on material quality and limit their application in the drying of certain high value-added materials.

[0003] The Chinese patent with publication number CN216080869U discloses a petrochemical solid material drying device, which includes a strip shell, a first support leg, a second support leg, a first gate valve, a discharge square pipe, a second gate valve, a feed hopper, an observation transparent plate, a hollow air outlet plate, a hot air blower, a connecting pipe, an air inlet hollow pipe, an air return pipe, an exhaust vertical pipe, a driving wheel, a driven wheel, a conveyor belt, a scraper, a reinforcing rib plate and a motor. The benefit of this patent is that the space formed between the strip shell and the scraper belt conveyor inside the strip shell provides a placement space for the material. The drive of the scraper belt conveyor allows the material to circulate in the strip shell, and the hot air blower generates dry hot air, which is blown onto the material through the hollow air outlet plate, so that the material can be dried cyclically and the drying effect is guaranteed.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing device can circulate the material in the strip shell by driving the scraper belt conveyor, and generate dry hot air through the hot air blower, which is blown onto the material through the hollow air outlet plate, so that the material can be circulated and dried, thereby ensuring the drying effect. However, the material is spread flat on the conveyor belt, and the hot air from the hot air blower can only be blown on the upper surface of the material, which will make it difficult to dry the side of the material in contact with the conveyor belt, thereby affecting the drying effect.
