[0002] Coal gangue is solid waste discharged during coal mining and coal washing. It is a kind of black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. After proper processing and treatment, it can be used as a raw material for water treatment filter media. In the process of processing coal gangue, in order to meet the production needs of different stages, intermittent air-blast feeding mechanisms are often used to transport materials.

[0010] Furthermore, a return arc is provided on the inner side of the air collecting tube to prevent the air flow inside the extension part from being lost.

[0011] Furthermore, a retaining slope is provided on the inner side of one end of the material pipe to prevent the gangue material from overflowing into the blast part.

[0012] Furthermore, the interior of the material pipe is provided with a sluice net in sections, which is located on the inner side of the outer ring frame to prevent the coal gangue material from overflowing outward.

[0013] Furthermore, an air supply pipe body mechanism docking with the outer ring frame is provided on one side of the air guide pipe.

[0027] See also Figure 1-4 As shown, the utility model is an intermittent air blast feeding device for coal gangue, comprising: a material pipe 1 and a discharge part 2 and a barrel 3 at its upper end, wherein the protruding tube body at one end of the discharge part 2 is used to connect with an external device for storing coal gangue materials;

[0028] A blasting part 4 is provided at one end of the material pipe 1, a ventilation groove 5 is provided at the upper end of the blasting part 4, an outer ring frame 6 is provided in sections on the outer side of the material pipe 1, and an air guide duct 7 is also provided on the outer side of the material pipe 1 to transport wind power to the inside of the material pipe 1 in sections through the outer ring frame 6 to enhance the feeding effect;

[0029] A guide plate 18 is provided on the inner side of the outer ring frame 6, and a spray head 19 is provided at the bottom of the guide plate 18 to gather the airflow to form a pressurized jet airflow, and a wind guide slope 16 is provided on the inner side of the material pipe 1 to guide the jet airflow to the material and the pipe wall;

[0030] The present embodiment provides a segmented air blowing feeding mechanism for coal gangue, which uses the air guide pipe 7 to transport the diverted airflow to the inside of the outer ring frame 6, and then transfers it to the inside of the material pipe 1 to form a segmented feeding effect, thereby avoiding the situation where the material lacks the force to form a blockage after being sent for a certain distance, and is suitable for long-distance stable feeding operations.

[0031] Among them, an outer ring pipe 8 connected to the air guide pipe 7 is arranged on the outside of the blowing part 4, a fan 9 is arranged inside the blowing part 4, and an air collecting tube 10 for gathering the wind generated by the fan 9 is also arranged inside the blowing part 4. The air collecting tube 10 is used to prevent the wind from dispersing outwards and affecting the feeding performance.

[0032] Among them, an induced draft tube 11 for diverting wind is arranged on the inner side of the wind collecting tube 10, and an extension part 12 for gathering the diverted airflow is also arranged on the inner side of the wind collecting tube 10. A connecting pipe 13 is arranged on the outer side of the extension part 12 to connect with the outer ring pipe 8, so that the diverted airflow can be directly transmitted to the inside of the outer ring pipe 8 for segmented transportation.

[0033] The inner side of the air collecting tube 10 is also provided with a return arc 14 to prevent the air flow inside the extension part 12 from being lost. The return arc 14 has an arc-shaped structure and is distributed in an annular manner on one side of the inner wall of the extension part 12 .

[0034] Among them, a retaining slope 15 is arranged on the inner side of one end of the material pipe 1 to prevent the coal gangue material from overflowing into the blast part 4, and the air flow can also be directed to the inner wall of the material pipe 1 to prevent the accumulation and residue of coal gangue material in the area adjacent to the blast part 4.

[0035] The interior of the material pipe 1 is provided with a segmented asphalt mesh 17, which is located on the inner side of the outer ring frame 6 and is used to prevent the coal gangue material from overflowing outward and ensure the stable feeding of the coal gangue.

[0037] It can be understood that the utility model can effectively prevent the lack of back force during long-distance air blowing and feeding. While implementing segmented air supply to enhance the feeding effect, the segmented wind force will also blow the residual material on the inner wall of the drop tube 1, automatically forming a clean surface that is conducive to subsequent feeding operations.

[0038] A specific application of the operating process of this embodiment is: when in use, the wind force generated by the fan 9 is gathered by the wind collecting tube 10 and diverted to the interior of the extension part 12 through the inner induced draft tube 11 thereof, and then transmitted to the interior of the outer ring tube 8 through the connecting frame tube 13 and transported to the interior of the outer ring frame 6 in sections by the air guide pipe 7. At this time, the wind force is gathered inward by the guide plate 18 and then ejected outward through the injection head 19. The ejected airflow is guided by the air guide slope 16 and then blown obliquely toward the material and the inner wall of the material pipe 1. While strengthening the feeding force to prevent accumulation and blockage, the material on the inner wall surface of the material pipe 1 can also be blown off to avoid the formation of dirt due to long-term residue, so as to ensure the subsequent feeding effect.
