Grading screen for spiral ore

Abstract

The invention relates to a grading screen for spiral ore. A base, a barrel body, a controller, a recycling pipe, a material throwing pipe, a water injecting pipe, a feeding pipe, a collecting mechanism and a plurality of supporting feet are included; the position of the feeding pipe is provided with a scattering mechanism; a grading mechanism is arranged at the position of the barrel body; the scattering mechanism comprises a first motor, a driving shaft, a transmission assembly, a sealing plate, a sealing block and two cranked levers; the collecting mechanism comprises a collecting box, a water pump, a backflow pipe, an overflow pipe, a material discharging pipe and a collecting assembly; and the collecting assembly comprises a first collecting net, a connection rod, a second collecting net and a supporting unit. According to the grading screen for the spiral ore, accumulated ore materials are subjected to scattering treatment through the scattering mechanism, the ore materials are conveyed into the barrel body according to a certain rate, and the situation that separation is not facilitated after ore material accumulating is avoided; and besides, the collecting mechanism can be used for conveniently collecting ore materials in different specific gravities, collected water flow is conveyed into the barrel body to be subjected to grading operation through the backflow pipe dueto the water pump, the water using amount of the device is reduced, and therefore the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of mining development equipment, in particular to a spiral mining grading screen. Background technique [0002] The grading screen for random beneficiation is one of the beneficiation equipment. Its operating principle is a kind of beneficiation equipment for mechanical separation by virtue of the different solid particles, so the sedimentation speed in the liquid is different. It can filter the material powder in the mill, screw the spiral plate into the mill feed port after the person, and discharge the filtered fine material from the overflow pipe, so it is widely used in the mineral processing process of mining. . [0003] However, during the use of the existing spiral mining grading sieve, the ore powder is usually agglomerated when feeding, and at this time some ore particles with a larger specific gravity are easy to surround the ore particles with a smaller specific gravity, making the specific gravity larger...

Problems solved by technology

[0003] However, during the use of the existing spiral mining grading sieve, the ore powder is usually agglomerated when feeding, and at this time some ore particles with a larger specific gravity are easy to surround the ore particles with a smaller specific gravity, making the specific gravity larger. Small ore particles cannot float above the liquid surface, resulting in poor screening effect. Not only that, when the equipment is running, it is necessary to ensure sufficient water inside the equipment, which leads to huge water consumption of the existing spiral mining grading screen, and also Caused unnecessary waste of water resources, thereby reducing the practicability of the existing spiral mine grading screen
