During construction, the support cage is first assembled on the top of the clinker silo, and then the truss 1 is welded into shape, there is a certain angle between the vertical plane where the upper chord 11 is located and the vertical plane where the lower chord 12 is located, and the trusses are connected by the diagonal web 13. 1. After the truss 1 is initially assembled and installed, the truss 1 is lifted by a crane and assembled on the top of the clinker silo, so that there is a certain angle between the truss 1 and the feed silo. It is first fixed by a crane, and several linear array trusses 1 are connected on the circumference of the ceiling. Then the equipment platform 2 grid is welded and assembled. The equipment platform 2 is fixed on the top of the truss 1, and the bottom of the truss 1 is fixed on the support cage. After forming a preliminary stable prototype structure, the crane is removed, and the remaining trusses 1 are gradually assembled. The trusses 1 are welded by cross bars. After the arc surface is formed, the scaffolding 3 is welded to the equipment platform 2, and the guide rail is connected to the lower side of the lower chord 12 through the rail frame. The guide rail has an I-shaped cross section, and is arranged in a spiral shape on the lower side of the lower chord 12. After the guide rail is fixed, the connecting tube 41 is fixed on the equipment platform 2, and the bottom end of the connecting tube 41 is fixedly connected to the spherical tube 42, and the outer side of the spherical tube 42 is sleeved with a spherical sleeve 43, and the spherical sleeve 43 is connected to the unloading tube 5 through a telescopic conveying pipe 4, and the telescopic conveying pipe 4 is a two-section structure, and the two sections of the telescopic conveying pipe 4 are connected by an arc tube 44. The upper half of the telescopic conveying pipe 4 is arranged parallel to the lower chord 12, and the telescopic conveying pipe 4 of the upper half is telescopic to adapt to different unloading positions, and the lower half of the telescopic conveying pipe 4 is telescopic to adapt to different unloading heights, so that the clinker in the conveyor belt connected to the equipment platform 2 can fall into the clinker warehouse at a specific position along the inside of the telescopic conveying pipe 4 without transfer, thereby reducing energy consumption and also reducing the dust stirred up.

[0031] Example 2: Figure 1-8As shown, an energy-saving and environmentally friendly clinker silo ceiling grid structure is provided. On the basis of Example 1, the telescopic conveying pipe 4 adopts the following specific structure, including a connecting pipe fixed to the equipment platform 2, the bottom end of the connecting pipe is fixedly connected to the spherical cylinder 42, the outer side of the spherical cylinder 42 is sleeved with a spherical sleeve 43, and the spherical sleeve 43 can be rotated and connected at any angle within a certain range relative to the spherical cylinder 42. The head and tail ends of the upper half telescopic conveying pipe 4 and the lower half telescopic conveying pipe 4 are respectively connected by a retractable steel cable 46, and one end of the retractable steel cable 46 is wound around the retractable cylinder coaxially fixedly connected to the output shaft of the retractable motor 47, and the retractable motor 47 rotates to make the retractable motor 47 rotate. The retractable steel cable 46 is rolled up or released. When the retractable steel cable 46 is released, the two adjacent tubes in the telescopic conveying tube 4 slide relative to each other, causing the telescopic conveying tube 4 to extend or contract. When the upper telescopic conveying tube 4 extends, the arc tube 44 connected to the telescopic conveying tube 4 and the lower telescopic conveying tube 4 connected to it slide on the track 6 under the action of gravity. The length of the telescopic conveying tube 4 is determined by the length of the retractable steel cable 46. Therefore, it is only necessary to control the length of the retractable steel cable 46 to control the position of the suspension structure 7, thereby controlling the position of the unloading tube 5 to achieve fixed-point unloading.

[0032] As the amount of material accumulation increases during fixed-point unloading, it is necessary to raise the height of the unloading barrel 5. However, an excessively high position will cause the clinker to fall uncontrollably during its free fall, causing more dust. Therefore, a lower-half telescopic conveying pipe 4 is provided to limit the falling of the material. During the fall, the clinker pile gradually rises, and the retracting and releasing steel is controlled by the retracting and releasing motor 47 connected to the lower-half telescopic conveying pipe 4 to control the retraction or release of the steel, and adjust the position of the unloading barrel 5 to maintain a small distance between the unloading barrel 5 and the material dropping point, thereby reducing dust. The telescopic conveying pipe 4 includes a multi-section pipe with a limiting slide groove on the outside. The pipe cross-section is rectangular. The next-level pipe is sleeved on the outside of the upper-level pipe and slides in close contact. The inner wall of the next-level pipe is fixedly connected to a slider that slides in the limiting slide groove to control the maximum sliding distance between the control pipes.

[0033] The suspension structure 7 includes a roller 75 that rolls on the track 6, and the roller 75 is rotatably connected to the wheel frame 74, and the wheel frame 74 is connected to the frame plate 73 of the suspension 72. The bottom of the suspension 72 is rotatably connected to the suspension rod 71, and the bottom end of the suspension rod 71 is fixed to the arc tube 44. One end of the upper telescopic tube is rotatably connected to the spherical tube 42, and the other end is rotatably connected to the suspension rod 71, so that the upper telescopic conveying pipe 4 can be in a state parallel to the lower chord rod 12 after telescoping, and the bottom end of the lower telescopic conveying pipe 4 is fixedly connected to the cylinder 45, and the inner side of the cylinder 45 is in close rotation with the rotating cylinder fixed on the top of the lower barrel 5 and is connected, so that the clinker passes through the connecting pipe, the telescopic conveying barrel of the upper half, the arc tube 44, and the telescopic conveying barrel of the lower half into the lower barrel 5, and is discharged from the bottom end of the lower barrel 5.

[0034] Example 3: Figure 1-8As shown, an energy-saving and environmentally friendly clinker warehouse ceiling grid structure is provided on the basis of Example 1, wherein an inclined guide plate 56 is arranged inside a discharge barrel 5 connected to the bottom end of the lower half telescopic conveying pipe 4, so that the falling materials are brought closer to the middle part of the discharge barrel 5, and the discharge barrel 5 is rotatably connected to the discharge wheel 55. The materials sliding down from the roof have a large gravitational potential energy. The discharge wheel 55 is used to block the materials, which can reduce the gravitational potential energy of the materials and reduce the aroused dust. At the same time, the gravitational potential energy is used to drive the suction structure connected to the discharge wheel 55 for transmission to operate, which can absorb the airflow at the bottom end of the discharge barrel 5 into the inside of the discharge barrel 5, so that the airflow forms a circulating airflow in the airflow channel 51, the discharge barrel 5 and the bottom end of the discharge barrel 5, which can suppress the dust in the circulating airflow and reduce the amount of dust.

[0035] The specific structure of the suction structure includes an air flow channel 51 fixed on the outside of the discharge barrel 5, an air suction channel 52 is provided inside the air flow channel 51, the air flow channel 51 and the air suction channel 52 are separated by a partition, the air suction structure is connected to the discharge wheel 55 through a transmission structure 54, the transmission structure 54 includes a slidable piston sheet 544 arranged in the air suction channel 52, the piston sheet 544 is fixedly connected to the piston rod 543, the piston rod 543 is rotatably connected to the connecting rod 542, the connecting rod 542 is rotatably connected to the cam 541, the cam 541 is rotatably connected to the discharge wheel 55, when the discharge wheel 55 is rotated by the gravity of the falling clinker, the cam 541 rotates to drive the connecting rod 542 to run, so that the piston rod 543 is fixed The connected piston piece 544 reciprocates in the air intake channel 52, and one-way valves 53 are respectively arranged at the top and bottom ends of the side of the air intake channel 52. A one-way air intake valve is arranged on the partition, and a one-way exhaust valve is arranged on the side wall of the discharge barrel 5. The discharge wheel 55 rotates to make the piston piece 544 run. The piston piece 544 allows the gas in the air flow channel 51 connected to the one-way air intake valve to enter the air intake channel 52, so that the air flow with dust enters the air intake channel 52, and the other side of the piston piece 544 is exhausted. When the piston piece 544 moves downward, the upper side of the piston piece 544 inhales air and the lower side exhausts air, and the air flow is continuously absorbed from the bottom of the discharge barrel 5 and sent into the interior of the discharge barrel 5, so that the dust and the falling clinker are mixed and fall again.

[0036] The one-way valve 53 adopts a valve plate 531 that is rotatably connected to the through hole and blocks the through hole. When the pressure on the side where the baffle 532 is set is greater than the pressure on the opposite side, the valve plate 531 opens under the action of pressure, allowing the airflow to enter the opposite side from the side where the baffle 532 is set. When the pressure on one side of the piston plate 544 in the pressure suction channel 52 increases, the one-way input valve closes under the action of the spring force and the airflow pressure, and the one-way output valve opens, allowing the airflow to enter the discharge barrel 5, thereby reducing the energy consumption of clinker transfer and reducing the dust generated during the clinker stacking process, which has the effect of energy saving and environmental protection.
