Description

Technical Field

[0001] This utility model relates to the field of ore transportation technology, and in particular to an anti-sticking conveying device for conveying materials after fine crushing of fluorite ore. Background Technology

[0002] Fluorite, as an important mineral resource, needs to be transported to other locations for further processing after being mined and crushed. Mined fluorite ore typically has a high water content, resulting in a large number of small, sticky fragments after crushing. Current transportation methods typically use belt conveyors for long-distance transport, but the following problems remain:

[0003] A large number of small and sticky fragments adhere to the surface of the belt. At the discharge end of the conveyor, due to the belt reversal, some sticky material is not completely ejected. Usually, a rigid scraper is installed at the discharge roller. However, the rigid scraper and the belt are in hard contact. On the one hand, it is difficult to ensure complete adhesion and the cleaning of sticky material is not thorough. On the other hand, the belt surface is easily damaged due to excessive pressure or uneven wear, which shortens the service life of the belt.

[0004] Therefore, a non-sticking conveying device for conveying materials after fine crushing of fluorite ore is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where rigid scrapers are difficult to effectively clean up adhered fragments and damage the surface of the conveyor belt. Therefore, this invention proposes an anti-sticking wall conveying device for conveying materials after fine crushing of fluorite ore.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-sticking conveying device for conveying materials after fine crushing of fluorite ore includes a belt conveyor with a feed end and a discharge end at both ends.

[0008] The elastic scraper mechanism includes a fixed base fixedly connected to the lower part of the unloading end of the belt conveyor. Two guide cylinders are fixedly connected to one side of the fixed base. Guide rods are slidably inserted into the interior of each guide cylinder. The same arc-shaped scraper is fixedly connected to the top of each guide rod. Limiting rings are fixedly connected to the middle of each guide rod. Springs are sleeved on the outer circumference of each guide rod. The two ends of the springs abut against the limiting rings and guide cylinders respectively through spring seats to provide elastic pressure so that the arc-shaped scraper presses against the belt below the unloading end.

[0009] The lubrication mechanism includes an oil roller rotatably connected to the bottom of the belt conveyor. The surface of the oil roller has multiple oil drain holes for lubricating oil to seep out to the belt surface. The outer circumference of the oil roller is in contact with the belt surface at the bottom of the belt conveyor. One end of the oil roller is equipped with a liquid delivery component to replenish the oil inside the oil roller.

[0010] In one possible design, the infusion assembly includes a rotary plug fixedly connected to one end of the oil roller and communicating with the inside of the oil roller, and an oil tank fixedly connected to the inside of the belt conveyor. The other end of the rotary plug is connected to a throttle valve via a pipe. The throttle valve is fixedly connected to one side of the oil tank and communicates with the inside of the oil tank.

[0011] In one possible design, a pedestrian walkway frame for workers to walk on is fixedly connected to one side of the belt conveyor, and an inlet pipe is fixedly connected to the top of the oil tank. A tank cover is threadedly connected to the top of the inlet pipe, and the tank cover is close to the pedestrian walkway frame.

[0012] In one possible design, a feed hopper is fixedly connected to the top of the feed end of the belt conveyor.

[0013] In one possible design, the surface of the arc-shaped scraper is made of rubber, and the outer circumference of the oil roller is made of sponge.

[0014] In one possible design, the belt conveyor has multiple rollers fixedly connected inside, arranged in groups of three at equal intervals to form an inverted trapezoid. The multiple rollers are used to support the belt and form the inverted trapezoidal structure.

[0015] In this application:

[0016] Before transporting materials, the belt passes through a lubrication mechanism. The oil roller rotates passively under the friction of the belt, and the oil stored inside slowly and evenly seeps out through the oil drain holes on the surface, coating the surface of the belt return section with an extremely thin oil film. This oil film not only significantly reduces the adhesion of materials but also protects the belt surface from damage. The oil tank continuously replenishes oil to the inside of the oil roller through a rotating plug. The rotating plug ensures that the oil circuit remains connected while the oil roller rotates freely. The oil roller is made of porous absorbent materials such as sponge, which can absorb and store a large amount of oil. Through capillary action and squeezing action, it continuously and slowly supplies oil to the belt from the oil drain holes, ensuring long-term and uniform lubrication and avoiding oil waste or leakage.

[0017] Fine fluorite mineral material falls from the feed hopper at the feed end onto the belt conveyor. The weight of the ore causes the belt to bend naturally, fitting against the bottom roller to form an inverted trapezoidal transport channel, preventing the ore from rolling off the sides.

[0018] The fine fluorite mineral material is conveyed to the unloading end. Most of the fluorite mineral material is thrown out, and a small amount of the adhered material remains on the surface of the belt. It is then transferred to the area below the unloading end by the belt. Under the constant elastic pressure provided by the spring, the arc-shaped scraper always keeps close contact with the lower surface of the belt below the unloading end. The scraper completely scrapes away the residual material that has been lubricated by the oil film and whose adhesion has been reduced. The scraped material falls together with most of the fluorite mineral material, completing the conveying process.

[0019] Beneficial effects: In this utility model, the anti-sticking conveying device for conveying fluorite ore after fine crushing, through the combined use of components such as spring, arc scraper, guide rod, and limit ring, ensures that the arc scraper is always in close contact with the lower surface of the belt below the unloading end under the constant elastic pressure provided by the spring, preventing the arc scraper from not being in close contact with the belt, which would result in incomplete cleaning of ore residue on the belt surface, thus improving the cleaning capacity of the equipment;

[0020] In this utility model, the anti-sticking conveying device for conveying fluorite ore after fine crushing utilizes components such as oil rollers, belts, arc-shaped scrapers, and rotary plugs. The oil rollers are passively rotated under the friction of the belt, and the oil stored inside slowly and evenly seeps out through the oil drain holes on the surface, coating the surface of the belt return section with an extremely thin oil film. This not only significantly reduces the adhesion of the material but also protects the belt surface from damage. In addition, the surface material of the arc-shaped scraper is made of rubber to prevent scratching the belt surface and improve the service life of the belt.

[0021] In this invention, an oil film is pre-attached to the surface of the belt by an oil roller, which protects the belt and reduces the adhesion of the material. When the ore material is unloaded, the arc-shaped scraper adheres to the surface of the belt under the action of the spring force, thoroughly cleaning the ore residue on the belt surface and improving cleaning efficiency.
