[0038] Please refer to Figures 1-2As shown, the purpose of the embodiment is to provide a coal power unit raw coal bunker with a sub-bunker structure, which comprises a raw coal bunker body 1, a feed bunker 11 arranged on the outer wall of the raw coal bunker body 1, and a bunker chamber formed between the outer wall of the raw coal bunker body 1 and the inner wall of the feed bunker 11. A bunker cover 12 is arranged above the feed bunker 11. A storage device 2 and a feeding device 4 are arranged in the raw coal bunker body 1. A discharge pipe 13 is fixedly connected to the inside of the raw coal bunker body 1. A anti-blocking device 3 is arranged in the discharge pipe 13. When the material is stored, the feeding device 4 guides and conveys the material in the feed bunker 11 to the inside of the raw coal bunker body 1, so that the material is stored in the inside of the raw coal bunker body 1. The inside of the raw coal bunker body 1 is provided with a plurality of storage devices 2, which form six independent chambers in the inside of the raw coal bunker body 1. Two chambers form a group, and three groups are vertically arranged, so that the storage device 2 stores the material in sub-bunker. When the material is discharged, the rotating anti-blocking device 3 makes the material flow alternately, which prevents the material from being blocked in the inside of the discharge pipe 13. At the same time, the rotating anti-blocking device 3 scrapes the material attached to the inner wall of the discharge pipe 13, which prevents the raw material from being blocked due to the attachment of the raw material to the inner wall of the raw coal bunker body 1, and further reduces the risk of blockage in the inside of the discharge pipe 13.

[0039] In order to achieve the above-mentioned effects, the structure is refined as follows: Figure 6 and Figure 7 As shown, the storage device 2 comprises a partition plate 22 fixedly connected between the outer wall of the discharge pipe 13 and the inner wall of the raw coal bunker body 1. The outer wall of the discharge pipe 13 and the inner wall of the raw coal bunker body 1 are fixedly connected with a plurality of symmetrical storage plates 21. A plurality of chambers are formed between the storage plates 21 and the partition plate 22. The uppermost chamber is sequentially a first chamber and a second chamber from left to right. The middle chamber is sequentially a third chamber and a fourth chamber from left to right. The lowermost chamber is sequentially a fifth chamber and a sixth chamber from left to right. The plurality of storage plates 21 facilitate the sub-bunker storage of the material. The discharge pipe 13 is provided with a plurality of discharge ports 24 arranged symmetrically in pairs on both sides. The storage plates 21 are inclined, and the inclined end of the storage plate 21 is flush with the discharge port 24. The discharge ports 24 of each chamber are arranged symmetrically in pairs, which facilitates the discharge of the material.

[0040] Please refer to Figures 4-7As shown, the outer wall of the raw coal bin body 1 and the inner wall of the feed bin 11 are fixedly connected with two groups of symmetrically arranged flow guide plates 45. The flow guide plates 45 are inclinedly arranged, and the inclined ends are flush with the feed ports 41. The length of the lower flow guide plate 45 is greater than that of the lower flow guide plate 45. In use, the material is poured from the bin cover 12 into the inside of the feed bin 11. Due to the lower end of the flow guide plate 45 being aligned with the feed port 41, the material is accumulated on the flow guide plate 45 under the guidance of the flow guide plates 45 of different lengths, which facilitates guiding the material to each feed port 41, and ensures that the material falling into each chamber is more uniform.

[0041] Please refer to Figures 1-4 and Figure 13 As shown, the upper end of the raw coal bin body 1 is fixedly connected with a double-head motor 48. The double-head motor 48 is fixedly connected with a transmission rod 47 at both ends. The end of the transmission rod 47 away from the double-head motor 48 is sleeved with a belt 46 at one end of a plurality of cylindrical rods 42. Starting the double-head motor 48 drives the transmission rod 47 to rotate, which drives the plurality of cylindrical rods 42 to rotate through the belt 46. The feeding device 4 includes a plurality of feed ports 41 opened on both sides of the raw coal bin body 1. The feed ports 41 are symmetrically arranged in pairs and arranged above each chamber. The feed bin 11 is rotatably connected with a plurality of symmetrically arranged cylindrical rods 42 on both sides. The cylindrical rods 42 are rotatably connected between the feed ports 41 and the storage plates 21. The rod wall of the cylindrical rod 42 is fixedly connected with a crushing plate 43, and the crushing plate 43 is arranged inside the feed port 41. The rod wall of the cylindrical rod 42 is fixedly connected with a helical blade 44, and the helical blade 44 is arranged on both sides of the crushing plate 43. The cylindrical rod 42 drives the helical blade 44 and the crushing plate 43 to rotate. Since the helical blade 44 is partially arranged in the flow guide plate 45, the rotating helical blade 44 facilitates guiding the material in the flow guide plate 45 to the feed port 41. When the material passes through the feed port 41, the simultaneously rotating crushing plate 43 crushes the material. The crushed material falls into the six chambers inside the raw coal bin body 1. The six chambers facilitate the storage of the material.

[0042] Considering that each chamber is inclined downward, the materials collide with each other during discharging, which easily causes blockage in the discharge pipe 13. Please refer to Figure 2 and Figures 9-12As shown, the anti-blocking device 3 comprises a support plate 31 fixedly connected inside the discharge pipe 13, the upper end of the support plate 31 is fixedly connected with a driving motor 32, the output end of the driving motor 32 penetrates the inside of the support plate 31 and is fixedly connected with a fixed rod 33, a plurality of moving plates 34 are fixedly connected on the fixed rod 33, and the moving plates 34 are respectively arranged at the intermediate positions of the two discharge ports 24, a notch 35 is formed on each of the moving plates 34, in the initial state, the moving plates 34 shield the discharge port 24 of each chamber, so that each chamber is in a sealed space, when discharging is needed, the driving motor 32 is started to rotate to drive the fixed rod 33 to rotate, the fixed rod 33 drives the moving plates 34 to rotate, when the moving plates 34 rotate, the notch 35 coincides with the discharge port 24, the discharge port 24 away from the end of the notch 35 is shielded, since the openings of the adjacent two moving plates 34 face opposite directions, the notches 35 of the upper and lower adjacent two moving plates 34 of the moving plate 34 at the intermediate position face the same direction, so that the first chamber, the fourth chamber and the fifth chamber are in an open state, the materials between the vertically adjacent two chambers are staggered to fall, the collision between the materials when falling is reduced, the flowability of the raw materials is increased, and the phenomenon of blocking of the materials when falling is avoided, so as to affect the speed of the raw materials falling.

[0043] In order to further control the discharging speed of the raw materials and the output of the raw materials, please refer to Figure 2 and Figures 9-11 As shown, the lower end of the inner wall of the discharge pipe 13 is rotatably connected with a connecting plate 36, the upper end of the connecting plate 36 is fixedly connected with the lower end of the fixed rod 33, a second through hole 39 is formed in the inside of the connecting plate 36, the materials fall into the discharge pipe 13 from the discharge port 24, at the same time, the rotating fixed rod 33 drives the connecting plate 36 to rotate, when the connecting plate 36 rotates, the second through hole 39 coincides with one first through hole 38 on the fixed plate 37, so that the materials in the discharge pipe 13 fall from the second through hole 39 and the first through hole 38 in turn;

[0044] When the materials in the first chamber, the fourth chamber and the fifth chamber fall, please refer to Figures 10-12 As shown, then the fixed rod 33 is rotated to drive the moving plates 34 to rotate, the notches 35 on the moving plates 34 respectively coincide with the discharge ports 24 below the second chamber, the third chamber and the sixth chamber, at this time, the second chamber, the third chamber and the sixth chamber are in an open state, at the same time, the fixed rod 33 drives the connecting plate 36 to rotate, when the connecting plate 36 rotates, the fixed plate 37 on the second through hole 39 coincides with the other first through hole 38 on the fixed plate 37, so that the materials fall from the fixed plate 37.

[0045] Considering that the materials have a large viscosity, the materials will adhere to the inner wall of the discharge pipe 13 when discharging, please refer to Figure 2 and Figure 10As shown, the fixed rod 33 is provided with inclined surfaces on both sides, and the inclined surfaces are attached to the inner wall of the discharge pipe 13. When the fixed rod 33 rotates, the two sides of the fixed rod 33 are attached to the inner wall of the discharge pipe 13. The fixed rod 33 scrapes off the materials attached to the inside of the discharge pipe 13, preventing the raw materials from adhering to the inner wall of the raw coal bunker body 1, thereby further reducing the risk of blockage inside the discharge pipe 13.

[0046] The raw coal bunker with the warehouse structure of the coal power unit of the present application can pour the materials from the warehouse cover 12 into the inside of the feeding bunker 11 in specific use. The materials are accumulated on the flow guide plate 45, which is convenient for guiding the materials to each feeding port 41, and ensures that the materials falling into each chamber are more uniform. The double-head motor 48 is started to drive the plurality of cylindrical rods 42 to rotate. The rotation of the cylindrical rod 42 drives the spiral blade 44 and the crushing plate 43 to rotate. The rotating spiral blade 44 is convenient for guiding the materials in the flow guide plate 45 to the feeding port 41, and the rotating crushing plate 43 crushes the materials to prevent the blockage of the discharge port caused by the oversized raw materials.

[0047] The six chambers are convenient for storing the materials in the warehouse, and the inclination of each chamber is convenient for the raw materials to be discharged.

[0048] Considering that each chamber is inclined downward, the materials collide with each other during discharging, which is easy to cause the blockage in the inside of the discharge pipe 13. In the initial state, the moving plate 34 shields the discharge port 24 of each chamber, so that each chamber is in a sealed space. When discharging is needed, the driving motor 32 is started to rotate and drive the fixed rod 33 to rotate. The fixed rod 33 drives the moving plate 34 to rotate. When the moving plate 34 rotates, the gap 35 coincides with the discharge port 24. The discharge port 24 away from the gap 35 is shielded. Since the openings of the adjacent two moving plates 34 are opposite, the gaps 35 of the moving plate 34 in the middle position are opposite to the upper and lower adjacent two moving plates 34, so that the first chamber, the fourth chamber and the fifth chamber are in an open state, and the materials between the adjacent two chambers in the vertical direction are staggered and discharged.

[0049] When the materials in the first chamber, the fourth chamber and the fifth chamber are dropped, the moving plate 34 is rotated, so that the gaps 35 on the moving plate 34 respectively coincide with the discharge ports 24 below the second chamber, the third chamber and the sixth chamber. At this time, the second chamber, the third chamber and the sixth chamber are in an open state, and the materials can be staggered and discharged, reducing the collision between the materials during falling, increasing the fluidity of the raw materials, and avoiding the blockage phenomenon during discharging of the materials, so as to affect the speed of discharging of the raw materials.

[0050] Considering that the material has large viscosity, the material will adhere to the inner wall of the discharge pipe 13 when discharging. When the fixing rod 33 rotates, the two sides of the fixing rod 33 are in close contact with the inner wall of the discharge pipe 13. The fixing rod 33 scrapes off the material adhered inside the discharge pipe 13, prevents the raw material from adhering to the inner wall of the raw coal bin body 1 to cause the raw material blockage phenomenon, and further reduces the blockage risk inside the discharge pipe 13.

[0051] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
