Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide production, in particular to a scraper machine for zinc oxide production. Background Art

[0002] Zinc oxide is a commonly used chemical additive, which is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, foods, batteries, flame retardants and other products. In the production process of zinc oxide, it is usually necessary to oxidize and roast the zinc concentrate. A scraper is usually used to transport the zinc concentrate. The existing scraper cannot control the feed amount of the zinc concentrate. In the process of transporting the zinc concentrate, no matter how much zinc concentrate there is, it will fall directly on the conveyor path of the scraper, which can easily damage the scraper due to excessive load. In addition, there are often some large-volume ores when feeding the zinc concentrate. These large-volume zinc concentrates directly fall on the scraper and easily damage the scraper. The larger zinc concentrate is also easy to get stuck at the feed port of the scraper, causing the feed port to be blocked.

[0003] For this reason, we design a scraper conveyor for zinc oxide production here. Utility Model Content

The baffles 33 on the two rotating shafts 32 are symmetrical to each other. The threads on the left and right sides of the worm 35 rotate in opposite directions. The two worm wheels 34 cooperate with the two threads on the worm 35 respectively. When the worm 35 rotates, the two rotating shafts 32 can be controlled to rotate clockwise and counterclockwise at the same time, respectively, so as to control the two baffles 33 to adjust the width of the spacing between them. The larger the spacing width between the two baffles 33, the greater the feeding amount of the scraper machine body 1, and vice versa, the smaller the feeding amount of the scraper machine body 1;
