A feeding device for conveying powdery raw materials

Abstract

The invention discloses a conveying device for conveying a powdery raw material. The conveying device comprises a base and a conveying tube which is vertically and fixedly arranged on the base, wherein a conveying shaft is arranged at the middle in the conveying tube, spiral blades adaptive to the inner wall of the conveying tube are arranged on the outer wall of the conveying shaft, and the bottom end of the conveying shaft is connected with an output shaft of a drive motor which is fixedly arranged on the base; a charge port is arranged in the sidewall of the lower end of the conveying tube; and a crushing bin is connected to the top end of the conveying tube, and a pouring tube used for pouring for a reaction kettle is connected to an outlet in the bottom end of the crushing bin. The powdery raw material is spirally conveyed to a high place through the conveying tube, pouring for the reaction kettle is facilitated, and a breaking role is played on agglomerations in the powdery raw material, thus the quality of the powdery raw material is improved.

Description

technical field [0001] The invention relates to a conveying device, in particular to a feeding device for conveying powdery raw materials. Background technique [0002] In chemical production, raw materials need to be added to the reactor through the feeding port. At present, the shape of the feeding port of most of the reactors that use manual feeding is trumpet-shaped, which is convenient for workers to feed; however, for some special reactors, the feeding The height of the mouth is high, so it is necessary to adapt the corresponding lifting equipment such as a hoist to cooperate with feeding. But the weight that hoist lifts each time is limited, just must restart hoist every time when needing to add material and hoist is lifted to a certain height and then feeds, and can not add in time, and uses very inconvenient.

Problems solved by technology

[0002] In chemical production, raw materials need to be added to the reactor through the feeding port. At present, the shape of the feeding port of most of the reactors that use manual feeding is trumpet-shaped, which is convenient for workers to feed; however, for some special reactors, the feeding The height of the mouth is high, so it is necessary to adapt the corresponding lifting equipment such as a hoist to cooperate with the feeding

However, the lifting weight of the hoist is limited each time. Every time you need to add material, you must restart the hoist to raise the hoist to a certain height before adding material, but it cannot be added in time, and it is very inconvenient to use.

In addition, due to a small amount of agglomeration and other phenomena in the powdery raw materials, if they are directly added to the reactor, it is not conducive to the reaction of the powdery raw materials after entering the reactor.
