Description

Technical Field

[0001] This utility model relates to the field of wind-powered coal preparation technology, specifically a dry coal preparation device with safety and environmental protection functions. Background Technology

[0002] With the continuous development of industry, the demand for the separation of various minerals, coal and other resources is increasing. Although traditional wet separation methods can achieve good separation results to a certain extent, they have problems such as high water consumption and the generation of a large amount of tailings wastewater. This not only increases production costs, but also puts great pressure on the environment. Dry separation equipment is often used because it does not require water or uses very little water. Dry separation equipment has gradually become the focus of research and development in the field of resource separation, aiming to achieve the goal of efficient, energy-saving and environmentally friendly resource separation.

[0003] While existing technologies can sort coal, the process often results in raw coal falling off the conveyor, affecting normal transport, poor feeding flow, safety, and the inconvenience of filtering coal dust. This leads to poor environmental performance, hinders normal production, and limits widespread adoption and practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a dry separation device with safe and environmentally friendly functions, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a dry coal preparation equipment with safe and environmentally friendly functions, including a wind-powered coal preparation component, a feeding component fixedly installed at the other end of the wind-powered coal preparation component, a vibration protection component provided on the outer surface of the wind-powered coal preparation component, a feeding component provided at the other end of the wind-powered coal preparation component away from the feeding component, a feeding machine one provided at the end of the wind-powered coal preparation component near the feeding component, the feeding component being located on top of the feeding machine one, a feeding machine two provided at the end of the wind-powered coal preparation component away from the feeding component and the feeding machine one, a discharge hopper provided on the outer surface of the feeding machine two, a conveying pipe provided on the outer surface of the wind-powered coal preparation component, a dust removal component provided at the bottom of the wind-powered coal preparation component, a connecting pipe communicating with the wind-powered coal preparation component on the outer surface of the dust removal component, and the conveying pipe communicating with the dust removal component.

[0006] Preferably, the feeding assembly includes a conveyor, the outer surface of which is provided with a feed hopper and a discharge hopper, the outer surface of which is fixedly mounted with a mounting frame and a positioning column, the outer surface of which is inserted with a insertion frame and a connecting frame, and the inner surface of which is fixedly mounted with a protective net.

[0007] The above technical solution involves pouring the coal material to be processed into the conveyor from the feed hopper, aligning the insert frame and connecting frame with the positioning posts, and inserting them to complete the installation. During the operation of the conveyor, the material is transported to the discharge hopper. The feed hopper facilitates the pouring of material into the conveyor, while the discharge hopper facilitates the flow of material out of the conveyor and into subsequent components. The mounting frame provides support points for the installation of the conveyor, making the installation more stable. The insert frame and connecting frame are installed through the positioning posts, making the installation process simple and convenient, and easy to disassemble and replace. The protective net can prevent material from splashing out during the conveying process, avoiding material waste and environmental pollution, while also ensuring the safety of operators.

[0008] Preferably, a rotating roller is fixedly installed on the inner surface of the insert frame, and a feeding roller is rotatably installed on the outer surface of the rotating roller.

[0009] Through the above technical solution, the rotation of the feeding roller can assist the material to move smoothly in the insertion frame, reduce the friction between the material and the insertion frame, and prevent the material from accumulating in the insertion frame. The rotating roller provides rotational support for the feeding roller, enabling the feeding roller to stably play an auxiliary feeding role, improving the smoothness of material conveying, and ensuring the normal operation of the feeding component.

[0010] Preferably, the wind-powered coal preparation assembly includes a coal preparation box, the outer surface of which has a feed inlet adapted to the feeding assembly, and the inner surface of which is fixedly installed with a gangue plate, a blower, a gangue weir and a coal discharge hopper, the coal discharge hopper being adapted to the unloading assembly.

[0011] Through the above technical solution, the material enters the coal preparation box through the feed inlet from the feeding component. The vibration motor is started, and the strong vibration generated by it causes the material in the coal preparation box to be in a loose and turbulent state. During this process, the coal and gangue jump and displace to different degrees due to their own gravity. The less dense coal jumps upward more easily under the vibration, while the denser gangue sinks relatively. At this time, the blower starts to generate wind power. Although the wind power is an auxiliary power, it can further blow the lighter coal particles that jump upward to a specific direction, so that they can enter the coal discharge hopper more smoothly. The heavier gangue falls onto the gangue plate. The gangue weir prevents the gangue from rolling around at will, causing the gangue to concentrate in a specific area. After sorting, the coal enters the feeding component through the coal discharge hopper.

[0012] Preferably, the vibration protection component includes a vibration motor, a protective box is provided on the outer surface of the vibration motor, a slot is provided on the inner surface of the protective box, and a plug plate is inserted and installed on the inner surface of the slot.

[0013] Through the above technical solution, the vibration source generated by the vibrating motor can prevent the material from accumulating in the wind-powered coal preparation component, keeping the material in a good loose and tumbling state, which greatly improves the sorting effect. In addition, the protective box can protect the vibrating motor, reduce its impact from the external environment, and extend the service life of the vibrating motor. The design of the slot and the insert plate facilitates the installation and disassembly of the protective box, making it convenient to maintain and repair the vibrating motor.

[0014] Preferably, the feeding assembly includes a protective hopper, a material distribution plate is fixedly installed on the inner surface of the protective hopper, and a protective cover that communicates with the protective hopper is fixedly installed on the top of the protective hopper.

[0015] With the above technical solution, the sorted coal enters the protective hopper from the coal outlet hopper. Inside the protective hopper, the material distribution plate evenly distributes the coal to different feeding paths. Then, the coal enters the feeder through the feeding path. The protective cover can prevent the coal from splashing out when entering the protective hopper.

[0016] Preferably, the dust removal assembly includes a dust removal box, an air outlet on the outer surface of the dust removal box, an installation frame and a filter bag body fixedly installed on the inner surface of the dust removal box, a collection box slidably connected to the inner surface of the dust removal box, a positioning hole one on the outer surface of the dust removal box, a limit frame fixedly installed on the outer surface of the collection box, a positioning bolt adapted to the positioning hole one fixedly installed on the outer surface of the limit frame, a positioning plate fixedly installed on the outer surface of the limit frame, a positioning hole two on the outer surface of the limit frame, and a temperature sensor, an electromagnetic sensor, a control switch and an alarm on the outer surface of the wind-powered coal preparation assembly.

[0017] Through the above technical solutions, the dust removal component can effectively filter coal dust generated during coal preparation, reduce coal dust emissions, and protect the environment. The design of the filter bag body and mounting frame ensures the dust removal effect. The collection box facilitates the collection of coal dust, and the installation and disassembly of the collection box are convenient through the cooperation of components such as positioning bolts and positioning holes, making it easy to clean coal dust and enabling the dust removal component to work continuously and stably. The temperature sensor monitors the temperature around the feeding component in real time. If the temperature rises abnormally, for example, if the temperature of the equipment component exceeds the preset safety value due to prolonged operation or failure, the temperature sensor will transmit a signal to the control switch. The electromagnetic sensor detects the material conveying status. When the material is blocked in the feeding component or the conveying speed is abnormal, the electromagnetic sensor senses the change in the electromagnetic properties of the material and feeds back a signal to the control switch. After receiving the abnormal signal from the temperature sensor or the electromagnetic sensor, the control switch will immediately stop the operation of the feeding component and related equipment to prevent the fault from spreading. At the same time, it will send a command to the alarm, which will issue an audible and visual alarm to remind the operator that the equipment is abnormal.

In addition, the protective net of the feeding component prevents material from splashing and ensures the safety of operators.

A connecting pipe 14 communicating with the wind-powered coal preparation component 2 is provided on the outer surface of the dust removal component 13. The conveying pipe 8 communicates with the dust removal component 13.

[0031] Specifically, the feeding assembly 1 includes a conveyor 101. The outer surface of the conveyor 101 is provided with a feed hopper 102 and a discharge hopper 110. A mounting frame 103 and a positioning post 104 are fixedly installed on the outer surface of the conveyor 101. An insertion frame 105 and a connecting frame 106 are inserted into the outer surface of the positioning post 104. A protective net 107 is fixedly installed on the inner surface of the connecting frame 106. The advantage is that the coal material to be processed is poured into the conveyor 101 from the feed hopper 102, and the insertion frame 105 and connecting frame 106 are aligned with the positioning post 104 and inserted to complete the installation. During operation, materials are conveyed to the discharge hopper 110 via conveyor 101. The feed hopper 102 facilitates the pouring of materials into the conveyor, while the discharge hopper 110 facilitates the flow of materials out of the conveyor and into subsequent components. The mounting frame 103 provides support points for the installation of the conveyor, making its installation more stable. The insertion frame 105 and the connecting frame 106 are installed via positioning columns 104. The installation process is simple and convenient, and it is easy to disassemble and replace. The protective net 107 can prevent materials from splashing out during the conveying process, avoiding material waste and environmental pollution, while also ensuring the safety of operators.

[0032] Specifically, a rotating roller 108 is fixedly installed on the inner surface of the insertion frame 105, and a feeding roller 109 is rotatably installed on the outer surface of the rotating roller 108. The advantage is that the rotation of the feeding roller 109 can assist the material to move smoothly within the insertion frame 105, reduce the friction between the material and the insertion frame 105, and prevent the material from accumulating inside the insertion frame 105. The rotating roller 108 provides rotational support for the feeding roller 109, enabling the feeding roller 109 to stably play an auxiliary feeding role, improving the smoothness of material conveying, and ensuring the normal operation of the feeding assembly.

[0033] Specifically, the wind-powered coal preparation assembly 2 includes a coal preparation box 201. The outer surface of the coal preparation box 201 is provided with a feed inlet 202 that is compatible with the feeding assembly 1. The inner surface of the coal preparation box 201 is fixedly installed with a gangue plate 203, a blower 204, a gangue weir 205, and a coal discharge hopper 206. The coal discharge hopper 206 is compatible with the unloading assembly 4. The advantage is that the material enters the coal preparation box 201 from the feeding assembly 1 through the feed inlet 202. When the vibration motor 301 is started, the strong vibration it generates causes the material in the coal preparation box 201 to become loose and turbulent. During this process, the coal and gangue, due to their own gravity, will jump and shift to different degrees. The less dense coal is more likely to jump upward under the vibration, while the denser gangue will sink relatively. At this time, the blower 204 starts to generate wind. Although the wind is an auxiliary power, it can further blow the lighter coal particles that jump upward to a specific direction, so that they can enter the coal discharge hopper 206 more smoothly. The heavier gangue falls on the gangue plate 203. The gangue weir 205 prevents the gangue from rolling around at will, causing the gangue to concentrate in a specific area. After sorting, the coal enters the feeding assembly 4 through the coal discharge hopper 206.

[0034] Example 2: Figure 2-7As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the vibration protection component 3 includes a vibration motor 301, a protective box 302 on the outer surface of the vibration motor 301, a slot 304 on the inner surface of the protective box 302, and an insert plate 303 inserted into the inner surface of the slot 304. The advantage is that the vibration source generated by the vibration motor 301 can easily prevent the material from accumulating in the air-powered coal preparation component 2, keeping the material in a good loose and turbulent state, which greatly improves the sorting effect. In addition, the protective box 302 can protect the vibration motor 301, reduce its impact from the external environment, and extend the service life of the vibration motor 301. The design of the slot 304 and the insert plate 303 facilitates the installation and disassembly of the protective box 302, and makes it convenient to maintain and repair the vibration motor 301.

[0036] Specifically, the feeding assembly 4 includes a protective hopper 401, a distribution plate 402 fixedly installed on the inner surface of the protective hopper 401, and a protective cover 403 that communicates with the protective hopper 401 fixedly installed on the top of the protective hopper 401. The advantage is that the sorted coal enters the protective hopper 401 from the coal outlet hopper 206. Inside the protective hopper 401, the distribution plate 402 evenly distributes the coal to different feeding paths. Then the coal enters the feeder 5 through the feeding path. The protective cover 403 can prevent the coal from splashing out when entering the protective hopper 401.

[0037] Specifically, the dust removal assembly 13 includes a dust collection box 1301, an air outlet 1302 on the outer surface of the dust collection box 1301, an installation frame 1303 and a filter bag body 1304 fixedly installed on the inner surface of the dust collection box 1301, a collection box 1305 slidably connected to the inner surface of the dust collection box 1301, a positioning hole 1306 on the outer surface of the dust collection box 1301, a limiting frame 1307 fixedly installed on the outer surface of the collection box 1305, and a positioning bolt 1308 adapted to the positioning hole 1306 fixedly installed on the outer surface of the limiting frame 1307. A positioning plate 1309 is fixedly installed on the outer surface, and a positioning hole 1310 is opened on the outer surface of the limiting frame 1307. The advantages are that the dust removal component 13 can effectively filter the coal dust generated during the coal preparation process, reduce coal dust emissions, and protect the environment. The setting of the bag body 1304 and the mounting frame 1303 ensures the dust removal effect. The collection box 1305 is convenient for collecting coal dust, and the installation and disassembly of the collection box 1305 are convenient through the cooperation of components such as the positioning bolt 1308 and the positioning hole 1306, which facilitates the cleaning of coal dust and enables the dust removal component 13 to work continuously and stably.

[0038] Working principle: During use, the coal material to be prepared is poured from the feed hopper 102 into the conveyor 101 of the feeding assembly 1. The mounting frame 103 on the outer surface of the conveyor 101 provides stable support for its installation. During the conveying process, the feeding roller 109 inside the insert frame 105, supported by the rotation of the rotating roller 108, assists the material to move smoothly within the insert frame 105, reducing the friction between the material and the insert frame 105 and preventing material accumulation. The material finally flows out through the discharge hopper 110 and enters the coal preparation box 201 of the wind-powered coal preparation assembly 2. The protective net 107 on the outer surface of the feeding assembly 1 prevents material splashing, ensuring safety and avoiding waste and environmental pollution. After entering the coal preparation box 201, the vibration motor 301 is started, and the strong vibration generated by it loosens the material. In the tumbling process, due to factors such as the weight, shape, and friction with the box wall, the less dense coal is more likely to jump upwards, while the denser gangue sinks relatively. Simultaneously, the blower 204 generates airflow, further blowing the lighter coal particles upwards in a specific direction, allowing them to smoothly enter the coal hopper 206. The heavier gangue falls onto the gangue plate 203, and the gangue weir 205 prevents the gangue from rolling freely, causing it to concentrate in a specific area. The sorted coal enters the protective hopper 401 of the feeding assembly 4 from the coal hopper 206. Inside the protective hopper 401, the distribution plate 402 evenly distributes the coal to different feeding paths before entering the feeder 5. The protective cover 403 on top of the protective hopper 401 prevents coal from splashing during entry. Throughout the operation, temperature sensor 9 monitors the ambient temperature of the feeding assembly 1 in real time. If the temperature rises abnormally, for example, if the temperature of a component exceeds the preset safety value due to prolonged operation or malfunction, temperature sensor 9 will transmit a signal to control switch 11. Electromagnetic sensor 10 detects the material conveying status. When the material becomes blocked or the conveying speed is abnormal in the feeding assembly 1, electromagnetic sensor 10 senses the change in the electromagnetic properties of the material and feeds back a signal to control switch 11. Upon receiving the abnormal signal from temperature sensor 9 or electromagnetic sensor 10, control switch 11 immediately stops the operation of feeding assembly 1 and related equipment to prevent the fault from escalating; simultaneously, it sends a command to alarm 12, which then issues an audible and visual alarm. The equipment is alerted to any abnormalities. In addition, the dust removal component 13 at the bottom of the wind-powered coal preparation component 2 treats the coal dust generated during the coal preparation process. The dust-laden gas enters the dust collection box 1301 through the connecting pipe 14. Inside the dust collection box 1301, the filter bag body 1304 on the mounting frame 1303 filters the coal dust. The purified gas is discharged from the air outlet 1302, while the coal dust falls into the collection box 1305. The collection box 1305 is easy to install and disassemble through the cooperation of components such as the positioning bolt 1308 and the positioning hole 1306, which facilitates the cleaning of coal dust and ensures that the dust removal component 13 works continuously and stably, reducing coal dust emissions and protecting the environment. Finally, the material processed by the feeder 1 5 can be further discharged through the feeder 2 7 and the discharge hopper 6.
