Description

Technical Field

[0001] This invention belongs to the field of ore conveying technology, and in particular relates to a conveying device used in mineral mining. Background Technology

[0002] Ore conveyor belts are mainly used in the mining, production, transfer and processing of coal and other ores. These coal mine conveyor belts are characterized by large transport capacity, strong load-bearing capacity and long transport distance. They are often used to transfer excavated coal, thereby reducing the cost of manual transportation and improving transportation efficiency.

[0003] During the transportation of ore after mining, the powder from the surface ore will be blown into the air by vibration, forming dust. When this dust floats in the air and is absorbed by the human body, it will affect human health. In addition, a large amount of ore dust entering the air increases the loss of ore. Summary of the Invention

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0028] Please see Figure 1 As shown, this invention is a conveying device used in mineral mining, including a U-shaped belt conveyor 100 for conveying ore. The two ends of the U-shaped belt conveyor 100 are respectively set at the mining point and the ore collection point. In order to prevent dust on the surface of the ore from escaping into the air during the conveying process, this invention has N atomizing water spraying humidification mechanisms 1 installed at equal intervals along the conveying direction of the U-shaped belt conveyor 100 on the upper frame. During use, the atomizing water spraying humidification mechanisms 1 spray water onto the surface of the ore conveyed on the belt to humidify it, thereby suppressing the generation of dust. At the same time, the N atomizing water spraying humidification mechanisms 1 are set to avoid the dust from being generated again after the surface moisture of the ore dries during long-distance conveying.

[0029] Specifically, the atomizing water spray humidification mechanism 1 includes a spray pipe arranged above the U-shaped belt conveyor 100, with the length direction of the spray pipe perpendicular to the conveying direction of the U-shaped belt conveyor 100; and spray holes are opened on the spray pipe.

[0030] It is understood that, in order to facilitate the adjustment of actual ambient temperature, humidity, and the humidity of the ore itself during use, and to minimize dust generation and water consumption, this invention sets several dust detectors A101 at equal intervals above the frame along the conveying direction of the U-shaped belt conveyor 100; and sets two dust detectors A101 between two adjacent atomizing water spraying humidification mechanisms 1; then, during use, when any dust detector A101 detects dust in the ore at that location, the atomizing water spraying humidification mechanism 1 closest to and in front of the dust detector A101 is controlled to start spraying water, and when the atomizing water spraying humidification mechanism 1 is originally in the spraying state, the spraying volume of the atomizing water spraying humidification mechanism 1 is controlled to increase.

[0031] Meanwhile, during long-term use of the U-shaped belt conveyor 100, ore dust easily adheres to the U-shaped belt conveyor 100 under the action of atomized water spray. At this time, during conveying, when the belt is located below the frame, the wet or even paste-like dust can easily and uncontrollably detach from the belt, causing pollution. Based on this, the present invention needs to clean the ore dust attached to the belt; that is, the present invention has M drying and dust removal mechanisms 2 installed at equal intervals on the frame below the U-shaped belt conveyor 100 along the direction away from the ore collection point, and a wet dust removal mechanism 3 installed on the frame below the U-shaped belt conveyor 100.

[0032] like Figure 3The wet cleaning mechanism 3 includes a U-shaped frame B30 with both ends installed below the frame of the U-shaped belt conveyor 100. A cleaning brush roller 31 is connected between the two opposite inner side walls of the U-shaped frame B30. A collection trough with a top opening is provided directly below the U-shaped frame B30. A crossbeam 33 is also fixed between the two opposite inner side walls of the U-shaped frame B30 located on one side of the cleaning brush roller 31. A linear module 32 is fixed on one side of the crossbeam 33. A brush roller cleaning module is connected to the slider side of the linear module 32 through at least one telescopic module C34. The brush roller cleaning module includes a rod 35. A number of comb teeth 36 are equally spaced on one side of the rod 35. A scraper plate 37 is connected between the opposite two side walls of the U-shaped frame B30. The scraper plate 37 is located at the comb teeth. Directly below tooth 36; when the telescopic module C34 is extended or retracted, the scraper 37 contacts the bottom side of the brush roller cleaning module; that is, during use, the cleaning brush roller 31 is used to clean the damp ore dust adhering to the belt, and then the comb teeth 36 are used to clean the damp ore dust adhering to the cleaning brush roller 31; in order to enhance the cleaning effect, during use, the slider of the linear module 32 is controlled to move along the length of the rod 35, thereby moving the rod 35 and changing the position of any comb tooth 36 relative to the bristles of the cleaning brush roller 31; and during use, the telescopic module C34 is used to move the rod 35 in the horizontal direction, thereby using the scraper 37 to remove the damp ore dust adhering to the comb teeth 36.

[0033] Specifically, such as Figure 2 The drying and dust removal mechanism 2 includes a U-shaped frame A20 installed at both ends below the frame of the U-shaped belt conveyor 100. The inner bottom side of the U-shaped frame A20 is connected to the bottom side of the box 22 via a telescopic module A21. The inner bottom side of the box 22 is connected to a cleaning scraper 25 via a telescopic module B24. Soft bristles 23 are provided at the port of the box 22. A cleaning brush 26 composed of hard bristles is provided on the top of the cleaning scraper 25. Several suction pipes 27 are provided on the inner walls of the box 22 on both sides of the cleaning scraper 25, facing the cleaning brush 26. The suction pipes 27 are connected to a dust extraction device. In use, the cleaning brush 26 is used to clean the dust adhering to the belt, and then the suction pipes 27 are used to extract the cleaned dust to avoid direct emission into the environment and pollution.

[0034] It is known that, for ease of control, a controller is also included, which is connected to a dust detector A101, a misting water spray humidification mechanism 1, a drying and dust removal mechanism 2, and a moist dust removal mechanism 3.

[0035] It is known that, in order to facilitate the control and activation of the corresponding drying and dust removal mechanism 2 during use, a drying and dust removal mechanism 2 is set between any two adjacent drying and dust removal mechanisms 2. When the drying status detection mechanism 5 detects that the area meets the requirements for dust removal by the drying and dust removal mechanism 2, the drying and dust removal mechanism 2 in front of the drying and dust removal mechanism 2 is activated for dust removal.

[0036] Specifically, such as Figure 4 Several drying state detection mechanisms 5 are installed at equal intervals above the frame of the U-shaped belt conveyor 100 along the conveying direction. The drying state detection mechanism 5 includes a U-shaped frame C50 installed below the frame of the U-shaped belt conveyor 100. A telescopic module D51 is connected to the inner bottom side of the U-shaped frame C50. The top of the telescopic module D51 is connected to a base plate 52. An infrared humidity detector and an infrared distance sensor are installed on the upper surface of the base plate 52, facing the U-shaped belt conveyor 100. The infrared humidity detector facilitates the detection of the humidity of dust adhering to the belt. The infrared distance sensor facilitates the automatic adjustment of the distance between the infrared humidity detector and the belt according to the actual situation.

[0037] To prevent dust and other particles from adhering to the infrared humidity detector and infrared distance sensor during long-term use, which could affect their detection accuracy and lifespan, such as... Figure 4-5 The present invention includes a transparent dust cover 55 on the upper surface of a substrate 52 for covering an infrared humidity detector and an infrared distance sensor; the infrared humidity detector and the infrared distance sensor are also provided with a water spray pipe 56 and an air spray pipe 57 facing the top surface of the transparent dust cover 55; the water spray pipe 56 is connected to the bottom side of a water storage tank 560, and a pipe body 561 is connected to the top of the water storage tank 560; a convex ring 562 is provided on the inner wall of the pipe body 561; a piston 564 that slides along the inner wall of the pipe body 561 is connected to the upper surface of the convex ring 562 by a spring A563; a piston rod 565 is connected to the top of the piston 564; and the water storage tank 560 is mounted on a U-shaped substrate. The inner bottom side of the frame C50; a vertical rod 58 is fixed to the inner bottom side of the U-shaped frame C50. A horizontal rod 581 located above the base plate 52 is set at the top of the vertical rod 58. An inner sleeve 591 and an outer sleeve 590 that are sealed to each other are fixed to the bottom side of the horizontal rod 581. A spring B is connected between the inner sleeve 591 and the outer sleeve 590. An air jet pipe 57 is connected to the bottom side of the inner sleeve 591. The top of the water tank 560 is provided with an opening with a diameter of 0.2cm. The opening is designed so that ambient gas can slowly enter the interior of the water tank 560 under natural conditions, keeping the interior of the water tank 560 at a similar pressure to the ambient air.

[0038] When the telescopic module D51 is in its normal state, the distance from the upper surface of the substrate 52 to the bottom of the outer sleeve 590 is L1, and the distance from the lower surface of the substrate 52 to the top surface of the piston rod 565 is L2. When the telescopic module D51 is controlled to retract to full retraction, the water stored in the water tank 560 is controlled to form a water flow and sprayed out through the spray pipe 56 to the top surface of the transparent dust cover 55, using the water flow to clean the top surface of the transparent dust cover 55. When the telescopic module D51 is controlled to extend to full extension, the gas stored in the inner sleeve 591 and the outer sleeve 590 is controlled to form an airflow and blown out through the jet pipe 57 to the top surface of the transparent dust cover 55. At this time, the blown airflow blows away the water containing water remaining on the top surface of the transparent dust cover 55, improving the cleaning effect.
