Description

Technical Field

[0001] This utility model relates to a tailings cleaning device for conveyor belts used in mining. Background Technology

[0002] In the process of transporting mining materials, belt conveyors, as common continuous conveying equipment, often accumulate large amounts of tail material at the tail end due to issues such as material adhesion and scattering. This not only increases the cleaning workload and affects equipment operating efficiency, but also easily causes dust pollution, endangering the on-site working environment and personnel health. Existing cleaning methods mostly rely on manual labor or simple scrapers, resulting in poor cleaning effects and failing to achieve efficient collection and reuse of tail material. There is an urgent need for a highly efficient and automated belt tail material cleaning device to improve overall operational efficiency and environmental protection. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology and provide a tailings cleaning device for mining material transport belts.

[0004] A tailings cleaning device for a mining material transport belt includes a belt conveyor. The belt conveyor includes a support frame, with a drive roller and a driven roller at each end of the support frame. The drive roller is connected to a drive motor, and the drive roller and the driven roller are connected by a conveyor belt. Several support rollers are also provided between the drive roller and the driven roller. A main cleaning mechanism and a negative pressure dust collection system are provided below the belt conveyor.

[0005] The main cleaning mechanism includes an elastic scraper assembly and a rotating wire brush roller. The elastic scraper assembly includes a scraper, one side of which is in contact with the surface of the belt, and the other side of which is rotatably connected to the base. A torsion spring for supporting the scraper is provided between the scraper and the base. The base is mounted on the support frame. The rotating wire brush roller includes a brush roller body, the upper surface of which is in contact with the surface of the belt. One side of the brush roller body is a support shaft and the other side is an input shaft. The support shaft and the input shaft are respectively connected to bearing seats on both sides of the base. The input shaft is connected to a micro motor on the base.

[0006] The negative pressure dust collection system is located below the main cleaning mechanism. The negative pressure dust collection system includes a collection tank with an inclined wire mesh on it. The wire mesh is connected to a mechanical vibrator. A centrifugal fan and a dust collection box are connected to one side of the collection tank, and a hopper is located below the slope on the other side of the collection tank.

[0007] As a further improvement, the scraper is made of polyurethane and is detachably connected to the base. When the scraper develops edge wear or deformation due to long-term use, maintenance can be completed by simply replacing the scraper, without disassembling the entire base, significantly reducing equipment maintenance costs and downtime.

[0008] As a further improvement, the rotatable connection structure between the scraper and the base is a hinge, with a torsion spring located between the two flaps of the hinge.

[0009] As a further improvement, the base includes L-shaped beams horizontally arranged on both sides of the support frame, and the L-shaped beams are connected to the support frame by vertically arranged connecting beams.

[0010] As a further improvement, the connecting beam is welded to the L-shaped beam, and the connecting beam is bolted to the support frame. The use of high-strength bolts for fixing facilitates precise adjustment of the base's horizontal position during installation and allows for quick disassembly when maintenance or component replacement is needed, thus balancing structural stability and ease of maintenance.

[0011] As a further improvement, a spring support is provided between the bearing housing and the base to provide support force for the brush roller body and to make the brush roller body fit tightly against the surface of the belt.

[0012] As a further improvement, a spring is provided between the wire mesh and the collection trough. The spring can buffer the impact force when the wire mesh shakes, reduce vibration damage to the collection trough body, and extend the overall service life of the equipment.

[0013] Beneficial effects:

[0014] 1. High cleaning efficiency: Through the combined action of the elastic scraper and the rotating wire brush roller, the adhering tail material on the belt can be thoroughly removed, avoiding accumulation;

[0015] 2. High degree of automation: The brush roller is driven by a micro motor, and the cleaning process requires no manual intervention;

[0016] 3. Waste material can be collected and reused: The negative pressure dust collection system can suck waste material and dust into the collection tank, and work with the hopper to realize material recycling;

[0017] 4. Reduce dust pollution: Combined with a wire mesh and mechanical vibrator structure, it effectively blocks and separates dust, improving the working environment;

[0018] 5. Reasonable structure and convenient installation: The device structure can be modularly assembled, and the connection method is flexible, which facilitates installation, disassembly and maintenance. Attached Figure Description

[0026] This embodiment provides a tailings cleaning device for a mining material transport belt, including a belt conveyor 1. The belt conveyor 1 is composed of a support frame with a drive roller and a driven roller, which are connected by a conveyor belt and equipped with several support rollers to support the running belt. The drive roller is connected to a drive motor to provide power.

[0027] A main cleaning mechanism 2 and a negative pressure dust collection system 3 are installed below the belt conveyor 1. The main cleaning mechanism 2 includes:

[0028] Elastic scraper assembly 21: One side of the scraper 211 is in contact with the belt surface, and the other side is rotatably connected to the base 23 via a hinge 212 structure. The hinge 212 is equipped with a torsion spring to provide elastic support force, so that the scraper 211 is always in close contact with the belt running surface. The scraper 211 is preferably made of polyurethane, which has good wear resistance and elasticity, and can be disassembled and replaced with the base 23.

[0029] Rotating wire brush roller 22: Its upper surface is in contact with the bottom surface of the belt for auxiliary cleaning. One side is a support shaft and the other side is an input shaft, which are respectively mounted on both sides of the base 23 through bearing seats 222. The input shaft is connected to a micro motor 223 to achieve active rotation cleaning.

[0030] The base 23 adopts an L-shaped beam structure, which is installed on the support frame on the left and right sides. The L-shaped beam is connected to the support frame through a vertical connecting beam. The connection method is that the connecting beam and the support frame are fixed with bolts, and the L-shaped beam and the connecting beam are welded together.

[0031] To further improve cleaning quality, a spring support 224 is provided below the bearing housing 222 to provide upward support force so that the brush roller body 221 always fits against the belt surface.

[0032] A negative pressure vacuum system 3 is installed below the main cleaning mechanism 2, including:

[0033] The collection trough 31 has an inclined wire mesh 32 on its top. The wire mesh 32 is connected to a mechanical vibrator 33 installed on the trough wall. It automatically shakes when the tail material falls to prevent dust from adhering.

[0034] Below the wire mesh 32 is a collection space, and the tailings eventually fall into the hopper 36 located below via a sloping ramp on one side;

[0035] On the other side, a centrifugal fan 34 is connected to a dust collection box 35, which uses negative pressure to adsorb and collect the cleaned dust, further purifying the environment.

[0036] To improve the stability and adaptability between the wire mesh 32 and the collection tank 31, a spring support is provided between them.

[0037] Through the synergistic effect of the above structures, the residual material at the tail end of the belt can be automatically and thoroughly cleaned, while the tail material is recycled and dust emissions are reduced.
