Ore feeding hopper device

Abstract

The invention discloses an ore feeding hopper device which is low in cost, easy to clean and capable of achieving continuous and stable discharging. The ore feeding hopper device comprises a hopper body, wherein the lower end of the hopper body is provided with a discharging port. The ore feeding hopper device further comprises at least two barrier plate layers and at least one stripping device, wherein the barrier plate layers are arranged along the inner circumference of the hopper body by one circle and sequentially arranged in the hopper body from bottom to top in a spaced mode, and the included angle a between the upper surface of each barrier plate layer and the vertical upward direction is smaller than or equal to 90 degrees; the stripping device is installed on the outer wall of the hopper body and can vibrate and / or rap the hopper body so as to enable ore to fall off. The barrier plate layers indirectly improve abrasion resistance of the hopper device, cost is lower, and the hopper device is good in abrasion resistance, easier to manufacture and suitable for application and popularization. The stripping device can guarantee continuity and stability of discharging and meanwhile facilitates cleaning and maintaining of the interior of the hopper device.

Description

technical field [0001] The invention relates to storage and unloading equipment, in particular to an ore feeding funnel device. Background technique [0002] The ore feeding funnel is widely used in mining enterprises. It is the storage and unloading equipment in the mechanical handling system of bulk minerals. It mainly plays the role of intermediate storage, system buffer and equalization operation. The ore feeding funnel can quickly concentrate the minerals in the funnel and enter the next process. The shape of the ore funnel is mostly conical, cylindrical or prismatic. Usually, the inside of the ore funnel is a cone with a discharge port on the lower side, and the minerals are discharged from the discharge port by their own weight. Smaller feed funnels are generally made of ordinary steel plates, and larger funnel devices are generally made by casting concrete and adding steel plates on the inner wall. In the production process, due to the physical and chemical charact...

AI Technical Summary

Problems solved by technology

Although the stepped crushing funnel prolongs the service life of the funnel, after the funnel has accumulated minerals for a period of time, especially after the minerals with finer particles and higher humidity have accumulated for a period of time, the discharge port of the funnel will be broken due to the inside of the funnel. The accumulation of minerals becomes narrower and even clogged, which affects the continuity and stability of funnel discharge; in addition, the cost of using wear-resistant liners is relatively high; although the bottom corner of the funnel is a transitional rounded corner, its interior is still not easy cleaning and maintenance
