Description

Technical Field

[0001] This utility model relates to a coal preparation machine system, specifically a novel skid-mounted pneumatic coal preparation machine system. Background Technology

[0002] Dry coal preparation is a method that uses air instead of water as the separating medium. Air-powered coal preparation machines are a type of equipment that applies this method. Compared to water-based jigging coal washing machines, air-powered coal preparation machines offer several advantages: a simpler process flow, eliminating the need for dewatering and drying; environmental friendliness, they avoid consuming precious water resources and the water pollution caused by the discharge of coal slurry from wet coal preparation plants; and lower investment and operating costs. In recent years, with technological advancements, air-powered coal preparation machines have been widely used in the coal industry. However, air-powered coal preparation also has some drawbacks. The most significant is that it generates substantial amounts of dust and noise, posing a threat to workers' health.

[0003] In existing technologies, dust removal devices are typically installed on the wind-powered coal preparation machine to meet environmental protection and dust control requirements. Besides the dust removal device, a complete wind-powered coal preparation system includes several parts such as a sorting device, a feeding device, a discharging device, and an air supply device. These devices each include various mechanisms, conveying devices, and connecting parts. In existing technologies, during the transportation, installation, and disassembly of the wind-powered coal preparation system, all components are transported, handled, and assembled separately. Furthermore, before reaching the installation site, a foundation must be constructed based on the site conditions to secure the installed components. Therefore, the main problems with existing wind-powered coal preparation systems are: all components must be assembled on-site, resulting in time-consuming and labor-intensive installation work, sometimes taking a month or longer; disassembly also presents time-consuming and labor-intensive issues; and, in existing systems, only the dust removal section is enclosed, while the rest of the components are exposed to the elements, posing a problem of environmental pollution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model aims to provide a novel skid-mounted wind-powered coal preparation machine system, which achieves efficient installation, disassembly, and transportation, and prevents dust pollution.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel skid-mounted pneumatic coal preparation machine system includes a sorting box, an air supply box, and a dust removal box. A sorting device is fixedly installed inside the sorting box, an air supply device is fixedly installed inside the air supply box, and a dust removal device is fixedly installed inside the dust removal box.

[0025] This implementation example Figure 1 , Figure 2 As shown, a novel skid-mounted wind-powered coal preparation machine system includes a sorting box 1, an air supply box 2, and a dust removal box. Each box is a rectangular cube with the sides of the cube forming the box frame 5. Each box has a plate fixed to its side wall to seal the side of the box. Plates are also fixed to the top surface of the sorting box 1 and the dust removal box. In order to better show the structural relationship between the box and its internal devices, the plate is omitted in the figure.

[0026] The air supply box 2 is fixedly installed adjacent to the dust collection box on the working plane, and is generally directly erected on the ground. The cross-sections of the sorting box 1 and the air supply box 2 are the same, so that the sorting box 1 is stacked on the air supply box 2, and the sorting box 1 and the air supply box 2 are connected. That is, the bottom surface of the sorting box 1 and the top surface of the air supply box 2 are not covered with plates, so that the space inside the dust collection box and the space formed by the sorting box 1 and the air supply box 2 are both closed spaces. Various air ducts are connected between the sorting box 1 and the dust collection box, and between the air supply box 2 and the dust collection box.

[0027] A sorting device is fixed inside the sorting box 1. The sorting device includes a frame 6 fixed inside the sorting box 1, a sorting host 7, a feeding device 8, and a discharging device (not all shown in the figure) mounted on the frame 6. The feeding device 8 is connected to an external feeding system (not shown in the figure) through a feed port on the sorting box 1. The discharging device is connected to an external discharging system (not shown in the figure) through a discharge port on the sorting box 1. The discharging device includes a clean coal discharging device 9 and a gangue discharging device (not shown in the figure). The lower part of the sorting host 7 is connected to the air supply device inside the air supply box 2 via a flexible connecting pipe 11. The air supply device provides air power to the sorting host 7. The type and specifications of the sorting host 7 can be selected according to production needs. A closable door (not shown in the figure) is provided on the sorting box 1 for personnel to pass through. When the closable door is closed, the box is kept closed. To facilitate workers standing inside the sorting box 1, a maintenance platform (not shown in the figure) is also laid around the sorting host 7.

[0028] An air supply device is fixedly installed inside the air supply box 2. The air supply device includes a fan 10 fixed on a support frame inside the air supply box 2. The fan 10 provides sorting air to the sorting host 7 through a flexible connecting pipe 11. The number of fans 10 can be set according to the type of sorting host 7. In this embodiment, three fans 10 are provided. The air volume of the fans 10 is adjustable and can provide continuous or pulsed air supply. The air supply device can use existing technology. A closable door (not shown in the figure) is provided on the air supply box 2 for people to pass through.

[0029] To avoid transportation and installation difficulties due to excessive box size, the dust collection box is fixed inside the dust collection chamber. In this embodiment, the dust collection chamber is divided into a first dust collection chamber 3 and a second dust collection chamber 4, stacked vertically. The first dust collection chamber 3 and the second dust collection chamber 4 have the same cross-section and are interconnected. The dust collection device is also correspondingly divided into two parts that can be fixed inside the chamber. In the wind-powered coal preparation industry, dust collection devices can generally be bag filters, cyclone dust collectors, or a combination of both. In this embodiment, a bag filter is used. Specifically, the filter bags of the bag filter (not shown in the figure) are fixed inside the first dust collection chamber 3, and the dust collection hopper 12 and ash discharge device 13 of the bag filter are fixed inside the second dust collection chamber 4. The ash discharge device 13 uses a screw conveyor to output the solid dust from the dust collection hopper 12. The aforementioned bag filter can be achieved using existing technology. The baghouse dust collector also includes an induced draft fan 14, an exhaust duct 15, and an exhaust pipe 16, all located outside the dust collection chamber. One end of the exhaust duct 15 is connected to the baghouse dust collector, and the other end is connected to the induced draft fan 14 and the exhaust pipe 16 in sequence. Under the action of the induced draft fan 14, the exhaust duct 15 draws out the clean air from the baghouse dust collector and discharges the clean air into the atmosphere through the exhaust pipe 16. A sealable door for personnel to pass through is also provided on the dust collection chamber.

[0030] Various types of air ducts are connected between the sorting box 1 and the dust removal box, and between the air supply box 2 and the dust removal box. The air ducts pass through each box through their duct openings. The air ducts include a suction pipe 17 and a dust removal air supply pipe 19. The suction pipe 17 connects the sorting device and the dust removal device, and the dust removal air supply pipe 19 connects the air supply device and the dust removal device. Specifically, a suction hood 18 is provided above the sorting host 7. One end of the suction pipe 17 is connected to the suction hood 18, and the other end is connected to a dust-laden gas inlet on the dust removal device. In this embodiment, two suction hoods 18 are provided above the sorting host 7, and correspondingly, two suction pipes 17 and two dust-laden gas inlets are also provided. When the sorting unit 7 is working, a large amount of dust-laden gas enters the bag filter through the dust suction hood 18 and the dust suction pipe 17. Large dust particles immediately fall into the dust collection hopper 12, while smaller dust particles are carried upwards by the air rotation and enter the dust collection filter bags, where they are trapped on the surface of the filter bags. The purified air enters the dust collection filter bags and is discharged sequentially through the air outlet pipe 15 and the exhaust pipe 16 above the dust collection device. The dust collection air supply pipe 19 is specifically connected between the fan 10 and the dust collection filter bags. The fan 10 provides airflow to the dust collection hopper 12. The air in the dust collection hopper is used to periodically spray the dust accumulated on the surface of the dust collection filter bags, causing it to fall into the dust collection hopper 12.

[0031] In this embodiment, the sorting box 1, air supply box 2, first dust collection box 3, second dust collection box 4, and their internally installed devices and ducts are transported to the installation site. Each of the sorting box 1, air supply box 2, first dust collection box 3, and second dust collection box 4 is equipped with sealable doors, duct openings, inlets, and outlets according to production and site requirements. The boxes are then placed, with the sorting box 1 stacked on top of the air supply box 2, and the first dust collection box 3 stacked on top of the second dust collection box 4. The boxes are then secured to the ground and to each other. The connecting components and ducts between the devices are then installed, and the system is connected to the external feeding and discharging systems. The box is then ready for use. When disassembly is required after production, the ducts and connecting components are removed, and the boxes can be directly transported.
