Description

Spray dryer

Technical Field

The utility model relates to the technical field of spray dryers, in particular to a spray dryer.

Background

The atomizer of the spray dryer disperses the material into tiny droplets like mist, the droplets enter the drying tower and contact with hot air, the hot air instantly evaporates the water dispersed into mist material quickly, the dried material enters the cyclone separator along with hot air, the cyclone separator separates the material from air, and the separated material enters the material collecting bottle downwards.

According to the publicly-disclosed spray dryer (publication number: CN 207153130U), when the mixed liquid is required to be atomized and sprayed out in the application, the mixed liquid is simultaneously atomized and sprayed out by the second spray head and the first spray head, so that the mixed liquid can uniformly spread over all the space of the dryer, the air-bearing area of the mixed liquid can be increased, quick drying is realized, when one spray head is blocked, other spray heads can continuously and normally work, the problem that the existing spray dryer cannot continuously and stably atomize mixed powder liquid due to the blocking of the spray heads is avoided, and the working time is delayed.

However, in the actual use process of the equipment, the delay of working time caused by the blockage of the spray heads is avoided through a plurality of groups of the spray heads, but the lack of cleaning function in the drying agent main body frame can cause that the inner wall of the drying agent main body frame is difficult to clean completely due to the fact that the attached material particles are difficult to clean, so that the subsequent drying effect of the drying machine main body frame is reduced; in view of this, we propose a spray dryer.
