Technical Field

[0001] The utility model relates to the technical field of dust collection, in particular to a dust discharging device for a dust collection tank. Background Art

[0002] In order to reduce the pollution caused by the dust generated during the powder conveying to the environment, the powder is often conveyed to a powder device, a screening device, a storage tank, etc. through a closed pipeline. When filling the storage tank, a connecting head needs to be provided on the tank body. An exhaust head is usually provided on the connecting head, and a collection tank for receiving dust is connected below it. At present, the collection tank and the connecting head are connected by means of flange screws.

[0021] A plurality of vertical rods 21 are provided at the lower end of the active column 2. The vertical rods 21 pass through the lower end of the dust collection tank 1. An active ring 22 is provided at the lower end of the vertical rods 21. A spring 23 is sleeved on the vertical rods 21. The spring 23 is located between the dust collection tank 1 and the active ring 22. A connecting plate 24 is provided on the outer circumference of the active ring 22. A vertical plate 26 is installed on the outer circumference of the lower end of the dust collection tank 1. A vertical hole 27 is opened on the vertical plate 26.
