Description

Iron picking device for mine mining and dressing system

Technical Field

The utility model belongs to the technical field of cleaning devices, and particularly relates to an iron picker for a mine mining and dressing system.

Background

The crusher and the belt conveyer which are commonly used in the mining and selecting system of the mine have accidents of scratching a belt or damaging the crusher due to the fact that the system passes iron to different degrees, the accidents are greatly influenced after the accidents occur, the picking and repairing time is long, the production recovery is difficult, and the economic loss is large.

At present, the iron ore system picks up the ironware in the metal mine mostly is the electromagnetism and picks up the ironware, and the electromagnetism picks up the ironware and is mostly the electromagnetic equipment of long-term work system, installs in band conveyer's upper portion, and the circular telegram produces powerful magnetic force and clears away the iron part that mixes in the material, makes the raw materials grade improve to can protect mechanical equipment such as grinding machine, breaker effectively, can also prevent because of big, long iron part scratch conveyor belt's incident emergence. However, the existing electromagnetic effect is not ideal, and the main reasons are as follows: firstly, iron ore has magnetism to pick up the iron ware interference big, and the small granule ore is picked up together with the miscellaneous iron easily. Secondly, the width of the iron ore system conveyor is large, the material layer is thick, and the miscellaneous iron is buried in the ore layer and can not be identified or picked up. Thirdly, the magnetic strength of the iron picker is not easy to control, the small iron picker has no effect, and overlarge iron and ore are adsorbed on the electromagnet to block the normal operation of the conveyor.

Disclosure of Invention

The utility model overcomes the defects in the prior art and provides the iron picking device for the mining and dressing system.

In order to solve the problems, the utility model adopts the following technical scheme:

the iron picker for the mine mining and sorting system comprises an electromagnetic iron picking mechanism and is characterized by also comprising a bracket, an iron picker body arranged at the upper part of the bracket and a roller screening mechanism,

the support is composed of four upright posts, two transverse struts and two longitudinal struts which are fixedly connected with the upper parts of the four upright posts,

the iron picking machine body comprises two vertical plates arranged on two longitudinal supports, an inclined plate arranged on a rear transverse support and connected with the end parts of the two vertical plates, three transverse support plates arranged on the upper parts of the two vertical plates, and a material layer separating baffle plate strip arranged on the lower part of the middle transverse support plate;

the roller screening mechanism is arranged at the lower part of the iron picking device body and consists of a plurality of rollers and a plurality of wear-resistant discs arranged on the rollers, and the wear-resistant discs on every two adjacent rollers are arranged in a staggered mode.

Preferably, the electromagnetic iron picking mechanism comprises an installation structure frame, a head wheel, a tail wheel and a driving motor which are arranged on the installation structure frame, an adhesive tape wound on the head wheel and the tail wheel, and an electromagnet arranged on the installation structure frame, wherein the head of the installation structure frame is fixedly arranged on the transverse supporting plate.

Preferably, the distance between the plurality of rollers is gradually increased from the feeding end to the discharging end.

The utility model has the advantages that:

because the iron picker body is provided with the roller screening mechanism and the material layer separating baffle plate strip, after iron ore raw materials of the conveyor enter the iron picker body, a part of small-granularity mineral materials are separated and fall onto the lower layer of belt, the other part of large-granularity material is paved on the roller screening mechanism, and then the iron impurity is picked up by the electromagnetic iron picking mechanism, so that the iron threatened to a conveying system and a crusher is guaranteed to be picked up before entering the conveying and crushing system, and belt scratching accidents and crusher iron passing accidents are avoided.

Detailed Description

The utility model is further illustrated by the following figures and examples.

As shown in figure 1, the iron picker for the mining and sorting system comprises an electromagnetic iron picking mechanism 4 and is characterized by further comprising a bracket 1, an iron picker body 2 and a roller screening mechanism 3 which are arranged at the upper part of the bracket 1,

the bracket 1 consists of four upright posts 11, two cross braces and two longitudinal braces 12 which are fixedly connected with the upper parts of the four upright posts 11,

the iron picking machine body 2 comprises two vertical plates 21 arranged on two longitudinal supports 12, an inclined plate 22 arranged on a rear transverse support and connected with the end parts of the two vertical plates 21, three transverse support plates 23 arranged on the upper parts of the two vertical plates 21, and a material layer separating baffle plate strip 24 arranged on the lower part of the middle transverse support plate 23;

the roller screening mechanism 3 is arranged at the lower part of the iron picking device body 2 and consists of a plurality of rollers 31 and a plurality of wear-resistant discs 32 arranged on the rollers 31, and the wear-resistant discs 32 on every two adjacent rollers 31 are arranged in a staggered mode. The arrangement of the wear-resistant discs 32 prolongs the service life of the rolling shaft 31, the gap of the rolling shaft can be changed by the size of the wear-resistant discs 32, and the adaptability to the change of the particle size of ore on site is stronger.

The distance between the plurality of rollers 31 is gradually increased from the feeding end to the discharging end. The roller arrangement is small in dense distance close to the feeding end, the distance close to the discharging end is gradually increased from 12mm to 70mm, and the purpose of preventing a long and thin iron device from falling to the upper part of a belt through a gap between the rollers to form the hidden danger of scratching the adhesive tape is achieved.

The electromagnetic iron picking mechanism comprises an installation structure frame 41, a head wheel 44, a tail wheel 42 and a driving motor which are arranged on the installation structure frame 41, an adhesive tape 43 wound on the head wheel 44 and the tail wheel 42 and an electromagnet 45 arranged on the installation structure frame 41, wherein the head of the installation structure frame 41 is fixedly arranged on a transverse support plate 23.

Wherein: fig. 3 shows a belt conveyor 5.

The working principle of the utility model is as follows:

the utility model can be arranged at the position of a conveyor tail scraper-trough conveyer, as shown in figure 2, an extended conveyor tail scraper-trough conveyer 6 is arranged at the rear part of the iron picking device, so that the ore collecting function is achieved, and the materials are prevented from scattering and falling. The materials enter from the feeding end of the iron picker body, firstly pass through the roller screening mechanism to disperse the material layer, separate partial small-granularity mineral materials and fall onto the lower layer of belt, the other part of large-granularity materials are spread on the roller screening mechanism and are leveled by the spread materials, and then the scrap iron is picked up through the electromagnetic iron picking mechanism, so that the iron picker threatening the conveying system and the crusher is guaranteed to be picked up before entering the conveying and crushing system, and belt scratching accidents and crusher iron passing accidents are avoided.
