Description

Technical Field

[0001] The utility model relates to the technical field of spray drying equipment, and more specifically, to a kaolin spray drying device. Background Art

[0002] Kaolin is a non-metallic mineral with a wide range of uses. It is also used in large quantities as a raw material for the production of heavy oil catalytic cracking catalysts. Heavy oil catalytic cracking catalysts made from kaolin are generally spray-dried during the production process to obtain small particles or dust particles. When the existing spray drying equipment is in use, the atomized slurry easily adheres to the inner wall of the heating shell. In order to ensure product quality, it is necessary to stop the machine regularly for cleaning, which will reduce production efficiency.

[0003] After searching, the Chinese patent with the announcement number CN215084902U discloses a spray drying device for kaolin production. The raw material is atomized by a centrifugal atomizer and then discharged into the shell. It is easy to use. The inner wall of the shell can be cleaned by a motor to ensure the cleanliness of the shell and reduce its impact on the product. The vibration of the shell during use can be reduced by a shock-absorbing spring to improve its stability. The hot air can be refluxed by a fan to reduce energy consumption and be more environmentally friendly. The atomized raw material can be quickly dried by a hot air blower, saving manpower.

[0004] However, when this structure is actually used, the atomized raw materials can be quickly dried through a hot air blower. The hot air is directly blown down from the top through the outside, so that the contact time between the raw materials and the hot air blown out by the hot air is short, resulting in difficulty for the hot air to evaporate the moisture in the mist-like raw materials, resulting in uneven drying of the raw materials, thus affecting the quality of the product.
