Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a zinc powder vibrating conveyor. Background Art

[0002] As we all know, zinc dust is primarily used in coatings, such as organic and inorganic zinc-rich anti-corrosion coatings. It's also used in the dye, metallurgy, chemical, and pharmaceutical industries. However, excessive inhalation of zinc dust can pose significant health risks. Zinc dust is easily dampened in humid air and reacts with the air's moisture to form white basic carbonates, which coat the surface of the zinc powder particles. This reaction not only causes the zinc powder to agglomerate but also can affect its chemical properties and intended use. For this reason, zinc powder is often transported within factories using enclosed screw conveyors.

[0003] For example, a Chinese utility model patent discloses a zinc powder conveying device (Announcement No. CN216862705U). The device includes a feed box, a screw conveying mechanism disposed inside the feed box, a large pulley sleeved on the output shaft of the screw conveying mechanism located outside the feed box, a drive mechanism disposed outside the feed box, the drive mechanism including a reducer, a small pulley connected to the output end of the reducer, the small pulley and the large pulley being connected via a belt drive, a bracket connected to the outer end of the reducer, a base disposed at the lower end of the bracket, vertical plates disposed on the base on both sides of the bracket, each vertical plate having an adjusting bolt inserted therethrough, a first locking nut screwed onto the free end of the adjusting bolt located inside the bracket, a waist-shaped groove disposed at the bottom of the bracket, and the bracket and the base being connected via a screw extending through the waist-shaped groove. Due to the coordinated arrangement of the bracket, the base, and the adjusting bolt, the belt between the large pulley and the small pulley can be kept in a tensioned state at all times, thereby improving the operating quality of the device. The device is suitable for industrial production and has strong practicality.

[0004] However, when the inventors implemented this device, they found the following defects: zinc powder itself has good hygroscopicity, and using a closed method to transport it can reduce the amount of moisture adsorbed by the zinc powder in the air. However, the partial agglomeration of the zinc powder material before transportation will not only cause blockage of the screw conveyor, but also affect the subsequent production of coatings, etc., and has certain limitations in use.
