Description

Technical Field

[0001] The invention relates to the technical field of roller kilns, and in particular to powder feeding equipment. Background Art

[0002] At present, the roller kiln is provided with a storage bin and a discharge tank, the storage bin and the discharge tank are connected, a conveying device is provided under the discharge tank, and a sagger is provided on the conveying device. After the sagger moves from one side under the discharge tank to directly under the discharge tank, the powder in the storage bin enters the sagger through the discharge tank. After the powder is loaded to a preset amount, the sagger moves from directly under the discharge tank to the other side of the discharge tank. During this process, some powder adheres to the inner side of the stainless steel tank wall of the discharge tank. After the feeding is stopped, the sagger leaves the entire bottom of the discharge tank. The powder adhered to the discharge tank will fall down due to mechanical vibration. In order to prevent the powder from falling onto the conveying device, a baffle is added in the prior art. After the feeding is completed, the sagger moves to the other side, and the baffle blocks the discharge port of the discharge tank, thereby preventing the powder from being scattered on the conveying device and the air. Although the baffle can prevent the powder from being scattered on the conveying device and the air in the prior art, when the powder collected on the baffle is sufficient, manual recovery and collection is required.
