Description

Technical Field

[0001] This utility model relates to the field of centrifugal spray dryers, specifically a centrifugal spray dryer drying chamber with heat insulation function. Background Technology

[0002] Centrifugal spray dryers utilize centrifugal force and spray technology to rapidly atomize liquid materials into tiny particles under the action of high-speed rotating centrifugal discs. The atomized material then evaporates rapidly upon contact with hot air in the drying chamber, thus achieving rapid drying of the material. They are widely used in industries such as pharmaceuticals, food, and chemicals.

[0003] The announcement number CN219922060U discloses a centrifugal spray dryer, which includes a drying barrel, a centrifugal atomizer, and a fan. A frame is fixedly installed on the drying barrel, and a feed pipe is provided at the top of the drying barrel. The centrifugal sprayer is connected to the feed pipe at a position inside the drying barrel.

[0004] The centrifugal spray dryer described above facilitates the cleaning of powder adhering to the barrel wall, reducing powder waste. However, during the drying process, heat is easily lost to the outside through the chamber, making it inconvenient to preheat and insulate the chamber. Furthermore, collisions with external objects can affect the chamber, reducing its protective and heat-insulating effects. Utility Model Content

[0007] A centrifugal spray dryer drying chamber with heat insulation function includes a chamber body. A drain pipe is installed at the bottom of the outside of the chamber body. A heat-conducting component is installed on the outside of the chamber body. A protective component is installed on the outside of the heat-conducting component. The heat-conducting component includes an isolation sleeve. The isolation sleeve is installed on the outside of the chamber body. A receiving cavity is provided between the isolation sleeve and the chamber body. Several support plates are fixedly installed inside the receiving cavity. Several through holes are opened on two sides of the support plates. A liquid inlet pipe is installed through the outside of the receiving cavity.

[0013] Preferably, a plurality of the support columns are fixed between the protective sleeve and the isolation sleeve in a ring arrangement, and the insulation board is located between the isolation sleeve and the protective sleeve to match.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) In this drying chamber, hot water is injected into the receiving cavity through the liquid inlet pipe by setting up a heat conduction component. The support plate is used to support the isolation sleeve. The receiving cavity and the support plate can preheat the chamber body. After being discharged through the drain pipe, the chamber body can be insulated to reduce heat transfer.

[0016] 2) This drying chamber, by setting up protective components, the protective cover is supported by support columns, which further reduces heat transfer. The protective cover and insulation board can provide cushioning for the protective cover, improve the protection of the chamber, and at the same time play an insulation role, reducing the impact on the interior of the chamber.
